Measurement and automation technology

Automatically running processes must also be controlled whether the required target movement has actually been achieved. Their monitoring is often more complex the faster and more precisely the production runs. Measurement technology is a crucial factor for the safety and quality of the products. Sensors for all measurement principles are used for this in numerous applications. They range from the simple OEM standard sensor to the completely new type of measuring systems for in-line inspection.

Sheet edge measurement prior to laser welding

The company „Paul von der Bank“ in Hilden (Germany) develops and manufactures modular-designed robotic welding cells and fully automatic production and processing lines. To ensure high production quality of longitudinally welded pipes, the following factors must be considered: Besides sheet edge length, the exact edge position must be known, it must be guaranteed that sheet edges are aligned perfectly to each other.

Bore hole depth

It is essential to measure in bore holes for some applications. In doing so, the depth or the wall structure of a bore hole can usually be measured. Only confocal axial or radial miniature sensors with 4 mm external diameter are suitable for this. Triangulation sensors would not provide any measurement results due to the shadowing of the laser in bore holes. The target material is not important for confocal sensors.

Thickness measurement of mineral cotton

Mineral cotton is often used for heating insulation of buildings.  However,  as  well  as  the  homogenous  material structure, thickness is also a critical factor in ensuring the right insulation characteristics. In the production two  optoNCDT  1700  laser  sensors  with  an  integrated controller and air purge system for protecting the optics are therefore required for quality control.

Processing measurement data for thickness measurements

One method of measuring thickness is to calculate values from two opposing distance sensors. With up to six inputs, the CSP2008 universal controller allows synchronous recording of measured values from optical sensors: A pair of sensors is connected directly to the controller, another pair is connected via the EtherCAT fieldbus coupler and an integrated extension terminal. Two analog sensors measure the width of the material. These sensors are connected via a dual-channel analog input terminal. After the sensors have recorded their values, the CSP2008 calculates material thickness and width. Three switching inputs are used to set masters as per a calibration standard.

Digital 3D measurement of complex parts and shapes

Mabotic devepols and manufactures various designs of digital scanning units. scanCONTROL laser scanner are often used for digitization of parts. The scanner projects a laser line onto the object being measured and records the profile of the line. When the scanner is mounted on a linear axis and the scanner traverses over the measurement target, a 3D image of the target can be generated.

Dimension inspection of cylindrical objects

The CD Express measuring instrument developed by a British company measures circumference, diameter and ovality of cylindrically shaped objects. The measuring objects are inserted in the measuring device and the measurement starts automatically. An optical micrometer from the optoCONTROL 2500 series operates in the measuring device.

Color measurement of liquid paint

Measuring the color of liquid paint is extremely complex. To date, paints have been typically applied on a test area first and then measured only after the drying process in order to achieve reliable measurement results. If the measurement results reveal that the paints are faulty, the paint con­tainers must be mixed again or even disposed of which partly involves long waiting times until a new measurement process can be started. In order to accelerate this process, Micro­Epsilon has developed a sys­tem that enables the measurement of liquid paint during the production process.

This application therefore includes the colorCONTROL ACS7000 color spectrometer for color measurements and the optoNCDT 1420­50 laser triangulation sensor for distance measurements. The latter is ideally sui­ted to this application due to its compact size and excellent performance. A linear unit offers automatic readjustments.

Color measurement of LED panels (RGB)

When RGB LED panels are produced, the challenge is to create a uniform, completely homogenous surface. Therefore, a diffuser layer is used, which enables a regular scattering of the otherwise point-shaped LED light. In order to avoid defects in the material and during production, the inline colorCONTROL ACS7000 color measurement system is used with the ACS3-TR receiver unit. Errors can therefore be recognized during the production process itself rather than the previous method of manual final inspection, which is no longer necessary.

Yarn thickness

A consistent yarn thickness is a prerequisite in the textile industry for high quality products. Therefore, the naturally occurring yarn thickness fluctuations must be eliminated. The yarn is drawn to a constant thickness using a stretching tool. The measured data for controlling the stretching tool are provided by an eddy current sensor which indirectly measures the thickness. The thickness is transmitted to the eddy current sensor using sensing rollers. After the stretching, the result of the processing operation is also checked by an eddy current sensor.

Overhead conveyor distance

Overhead conveyors which move automatically through the production process on a rail are used for the transportation of many components. A certain minimum distance is required so that components do not collide with each other during the transport. The optoNCDT ILR sensors have the task of maintaining this minimum distance. Attached to each overhead conveyor, they measure the distance to the next one. These sensors measure using the “Time-of-Flight” principle which is ideal for such types of application.

Measurement system for the flat setting on carding machines

The setting of the distance between the drum and the flat is crucial for carding quality of fiber, e.g. wool. Investigations have shown that manual gap settings with the gage to the left and right on the carding machine are not equal and that with the machine at standstill slight deviations from the operating conditions arise. The remedy is provided by a measuring flat rod (FCT) with two or three capacitive sensors which is exchanged for a flat rod. The sensors measure the distance to the drum via the drum width. The other distance signals are passed to the PC. The fully automatic measurement sequence eliminates erroneous settings and shortens the setup time. The inspection and documentation of the results facilitates practical quality assurance.

Active compensation for movements in the measurement process

Harsh industrial environments place high demands on optical displacement sensors – precise measurements must still take place despite dust and high processing speeds. The optoNCDT 1700 and optoNCDT 2300 series of laser sensors have been mastering these challenges for many years. However, if motion disturbances (e.g. belt movements, radial movements of pulleys, and base body vibrations) occur that are greater than the object being measured, the measurement process may be impeded or made impossible. Examples include folds in a belt.

Bearing shell surface

Sliding bearings are used in combustion engines for the crankshaft and camshaft. The bearing shells are often composed of three layers whereby the inner layer is only metalized or sputtered. If there are residues on the bearing shell, the inner layer has too little purchase and flakes off. The system from Micro-Epsilon checks all bearing shells at the end of the production for a faultless condition of the surface. A BV camera records an image of each shell which is evaluated afterwards completely automatically. If necessary, the system also takes over the selection afterwards depending on the measurement result.

Thickness measurement using displacement sensors

Thickness measurement using displacement sensors is a wide application area. Basically there are distinctions between non-destructive/destructive, non-contact/with contact and one-side/two-sided thickness measurement. The Micro-Epsilon measuring techniques for thickness measurement are all emission-free whereby no emissions regulations of any kind have to be complied with. Thickness measurements must be performed both with contacting as well as with non-contact sensors whereby non-contact measuring techniques show advantages as regards accuracy and measuring speed. There is also a distinction between one-sided and two-sided thickness measurement. Two-sided thickness measurements are carried out with at least one pair of sensors which are installed together on one axis. This pair of sensors measures the target synchronously. The difference between the measurement results (C-A-B) produces the thickness of the measuring object. One-sided thickness measurements must only be performed with non-contact sensors. In doing so, the target is only measured with one sensor and either only a part of the target thickness (e.g. layer thickness) or the complete measuring object thickness is measured. Thickness measurements are mainly used in process control and quality assurance, e.g. for the control of extrusion systems or 100% checking of tube diameters.

Measuring of the haptic contact temperature

Contact or touch temperature is an important parameter in the tactile quality of a surface. The feeling of the temperature that a material causes can be determined by using a measuring system. If this parameter is known, an objective feeling of quality can be made. The measurement results are shown on a sensotact-scale – a tactile reference system. A physical basis for these values is created by measuring the temperature of the surface shim. Afterwards a step-less measuring analog of the reference scale is possible. In the measuring system, temperature sensors of the thermoMETER CSmicro series are used.

Dimensional accuracy of sectional doors

With sectional doors for parquet or laminate flooring, key and slot joints for individual sections are applied. However, these sections are opened and closed frequently. To enable a robust but permanent flexible key and slot joint, specified  dimensions  are  critical  and  must  be  adhered to. This is particularly important in the case of significant temperature differences or inaccurate dimensions, where the door could be locked or positioned incorrectly. The measurement of the key and slot joint is therefore critical in ensuring the correct manufacturing dimensions.

Release of satellites into space

In order to be able to launch a satellite from the Areane rocket unobstructed into space, the nose cone section, together with the side shield, have to be separated from the main rocket immediately before the release of the satellite. Simultaneous and controlled activation of a series of preloaded springs, provide the propulsion force for the separation of the nose cone and side shield. It is of vital importance that the section separates itself in an absloute linear motion from the main rocket, with-out any non-linear tumbling movement that could cause damage to the satellite. The separation movement is controlled by 3 Draw-wire sensors mounted on the booster rocket.

Release of satellites into space

If satellites are put into the Earth’s orbit, it is necessary to separate the cone of the rocket from the satellites of the rocket itself. After unlatching the retainer for the nosecones, spring assemblies provide the necessary thrust to put the satellite carriers at the necessary distance. As this movement must be completely linear, the separation maneuvere is monitored by draw-wire sensors from Micro-Epsilon. Several sensors are attached to the rocket. The tip of the wire is connected to the cone of the rocket. A predetermined breaking point in the wire separates both flying objects from each other when the measuring range has been exhausted. The remaining wire is retracted by the spring effect of the winch drum so that it cannot get entangled anywhere. The sensors based on the WDS-500-MP were specially modified for this application.

Application consulting for sensors and systems

Dimensions, tolerances, sorting, part recognition

Dimensions usually designate the significant linear dimensions of an object. Dimensions can be measured in different ways. Under certain circumstances, one sensor can measure the complete dimensions for small objects. Image processing systems, laser profile sensors and ThruBeam micrometers are particularly capable of detecting complete dimensions. For larger measuring objects, the measurement can be performed using sensors which move along one edge of the target and thus measure the object dimensions. One alternative to this is that the dimension is measured with a static sensor and moving measuring objects as is typically the case for assembly lines.

Compressor/turbine gap, revolutions

When parts are rotating, their speed can always be measured. Speed sensors which are directly attached to the shaft are usually suitable for this. If this is not possible, other measuring principles must be used where, e.g. the rotating part is measured on the front side. In order to reliably measure the speed in this arrangement, defined points per revolution must be measured. Eddy current sensors, capacitive and laser sensors are used for this.

__________________________________________________________________________________________________________

Deflection, deformation, waviness

If objects are loaded with a weight or moved free-standing over a certain distance, a smaller or larger warping of the object always occurs. Measuring this deflection can be accomplished for larger objects using all possible distance sensors. On the other hand, if the deflection of a small slab should be measured, high precision measuring systems like those developed by Micro-Epsilon are necessary for this. Deflections from the metre range down to trillionths of a metre can be measured at Micro-Epsilon.

__________________________________________________________________________________________________________

Eccentricity, diameter, concentricity

The diameter of an object can be established in different ways. If the center of the object is known, a single sensor is sufficient for the measurement whose result is evaluated with the position of the center point or the axis. If the position of the center point is not known, the diameter is measured directly using two sensors. The distance information here is also evaluated together. In particular cases, if the opaqueness of the object allows this, the determination of the diameter can also be made directly using a confocal sensor.

__________________________________________________________________________________________________________

Detection of color

Every visible body emits light, which is why color can be used to evaluate objects in automation technology. Sensors sort products by color, inspect incoming goods, detect color and print marks, control LED intensity and color, and much more.

Filling level

Filling levels can be measured directly or indirectly in many ways using displacement sensors. The confocal principle is usually applied for liquids in doing so. The filling level measurement for solids is comparable with a distance measurement. Micro-Epsilon makes many different options possible due to the extensive range of different sensors.

__________________________________________________________________________________________________________

Lifting height, lifting

Lifting height is a factor which must be measured very frequently. A lifting height measurement is necessary everywhere where automatic lifting processes should make the daily work easier. 
The measurement system can be installed subsequently or already considered and integrated during the planning of the system.

__________________________________________________________________________________________________________

Centering, positioning, tilt, alignment

Different parts must often be positioned or products put in a specified place in production systems or for automatic movements. Thereby, sensors can only transmit the distance information to the controller or perform the complete system regulation with its signals. Welding robots with automatic weld seam guidance are an example of automatic regulation. Different sensors are used depending on which material the part to be positioned is made of.

__________________________________________________________________________________________________________

Profile, Contour, Surface

The surface or the surface profile is frequently a decisive factor in quality inspection. Laser scanners from Micro-Epsilon are frequently used for this. If traversing laser point sensors are used, these also measure a profile of the surface. The profile measurement is often used on robots or inspection systems for controlling further processes.

__________________________________________________________________________________________________________

Width

The width of an object is often an important aspect for dimension control. The width can in some circumstances be interpreted as thickness and can therefore be resolved using thickness measurement. Different measuring principles come into consideration for the width measurement depending on the size of the object. For large objects such as strip material or packages, the measurement data from two sensors are usually calculated together. Optical methods such as Thru-Beam laser micrometers, laser sensors or eddy current and capacitive sensors are suitable for this. One sensor which measures the object width with one measurement is often sufficient for smaller objects such as individually packaged goods. scanCONTROL split beam sensors or vision4A image processing systems are suitable for this.

__________________________________________________________________________________________________________

Gap, roller gap, roller convexity

If two object edges are joined together, a gap always remains. If the gap has to satisfy technical or visual requirements, the course with respect to the size must be checked. If the gap should be measured completely, laser scanners in the scanCONTROL series are ideally suitable for this. Point laser sensors in the optoNCDT group are also used for precise gap measurement over a track.

__________________________________________________________________________________________________________

Temperature measurement, surface temperature, intelligent pyrometer

Temperature is a critical factor in many processes and must often be measured. Non-contact infrared measurement is often the better alternative for this as compared with tactile methods. Temperature measurement without this method can no longer be imagined for machine maintenance, process control and quality control. Intelligent handheld units are used for mobile usage. Stationary IR sensors are suitable if the temperature has to be permanently measured at one position.

__________________________________________________________________________________________________________

Distance

Measuring distance, often also called displacement describes measuring the distance between 2 points. This distance is defined in the measuring technique by the distance of the sensor from the target. Thus, the distance measurement can also be designated as displacement, distance or position measurement. Displacement measurements in geometric measuring technology can be found in almost all application areas. Different criteria are included for the selection of the appropriate sensor for displacement measurements. The frequency of the distance change can be quasi static or high frequency and determines the measuring speed of the sensor. Contacting / non-contact Measurement range (displacement change in mm µm) Accuracy of the respective displacement position.
