Laser Displacement Sensor in Automated Guided Vehicle
APPLICATION: As there are more demands to build SMART factories in Singapore, there is a company working with semi-conductors industries to provide AGV(Automated Guided Vehicle) within the production floor to pick up the wafer rack and transport within the factory.
SOLUTION: ILD1420-500 provide high accuracy of 0.2% for 500mm measuring range, and sampling speed of 4kHz. Comes with a compact size, the ILD1420-500 not only provide high performance, but also provides digital signal to bring data into the computer. |
Accuracy Displacement Monitoring in Packaging Machine
APPLICATION: Packaging machine which are used for sealing the products into packets often faced challenges to determine if package is OK/NOK.
SOLUTION: Our proposed solution, eddyNCDT 3100 with S2 sensor, has high repeatibilities of less than 2um which enable the system to pick up the good and bad seals, but also the nature of this technology to work with high temperature up to 100?C. |
Varying Material Characteristics
APPLICATION: When the process parameters and conditions are different, normally it will lead to varying material characteristics, such as deformation.
SOLUTION: By using 3D scanner, the sample parts are scanned and all the point clouds are sent to compare with the master part point clouds. When two point clouds are combined to one 3D model, analysis and qualification are done on sample point clouds. |
High Mix and Low Volume
APPLICATION: For the maintenance, repair, and overhaul company, the job scope is high mix and low volume application.
SOLUTION: 3D scanner is used to scan through the worn parts and then the point clouds are sent to software and controller for analysis. The robot arm will then carry out the repairing job (grinding, welding etc) based on the analysis from the controller. |
Inspection and Maintenance of Pipelines
For the maintenance of pipelines, the inspection of the outer weld seam is a decisive and important criterion. For this purpose, the profiles of the weld seams are inspected in a test station. In order to automate the inspection process, the test facility is positioned precisely over the seam. The profile scanner detects the position of the weld seam and outputs the point clouds to the control system, the alarm will be triggered if the weld dimension is over the tolerance. Using high dynamic range mode of profile scanner, it can automatically adapts the exposure time to surface changes (e.g. moisture, dirt or corrosion). |
Laser Caddling
Laser profile scanners from Micro-Epsilon are used to detect the contour and shape of parts during laser cladding. These scanners detect the exact contour of the part before the weld is deposited, and then point clouds are sent to controller. 3D data is formed from the point clouds and it is used for the guidance of the weld head. |
3D Shape Measurement of Wafers
APPLICATION: Wafer flatness checking is very important to ensure the functionality of semiconductor chips. Due to the mirror like surface property of wafer, typical lasers are unable to give an accurate measurement value for flatness checking.
SOLUTION: reflectCONTROL deflectometry systems are used to detect the flatness or planarity of 150 mm wafers. These measure the flatness with only one image. For this purpose, the sensors project a striped pattern onto the wafer, which is recorded by the integrated cameras. Geometrical deviations on the wafer cause a distortion of the striped pattern, which is evaluated by the software. The sensor provides a highly accurate 3D representation of the reflective surface based on which the topology can be determined to micrometer accuracy. |
Positioning the Wafer Stage Using Capacitive Sensors
APPLICATION: The position of wafer stage is very important for alignment during the photolithography process. Misalignment will cause the flaw of circuit printed on the wafer surface.
SOLUTION: Capacitive displacement sensors are used for fine positioning tasks in the wafer stage. These sensors measure the position of the stage at various points, which is particularly useful for fine alignment. Thanks to their triaxial design, the sensors are insensitive to electromagnetic fields and achieve a resolution in the nanometer range. Furthermore, the sensors offer extremely high long-term stability. The non-contact sensors are designed for the vacuum range and can also be used in the UHV range. |
Laser Optical Level Measurement in Silos
The company Brückner Maschinenbau GmbH & Co. KG is the world's leading supplier of production equipment for manufacturing high-quality monoaxially and biaxially stretched films. These are used as packaging material or in high-tech applications, for example for electromobility, energy generation and storage or media technology.
For years, Brückner Maschinenbau has been using Micro Epsilon laser distance sensors to monitor the fill level in silos. Plastic granulate is stored in the silos, which is used for the production of films. In order to avoid production downtimes due to a lack of material, the fill levels in the storage silos must therefore be reliably and automatically recorded.
An optoNCDT ILR2250-100 specially adapted for Brückner Maschinenbau is used for this purpose. The sensor is equipped with an air pressure flushing system to counteract the high dust formation. The sensors are mounted on the silo roof and measure the bulk material or granulate. From there, they measure the filling and emptying of the silos in real time and guarantee a smooth flow of production and logistics processes.
Thanks to the use of the sensors, production stoppages due to missing material are avoided and costs are significantly reduced. Retrofitting the laser runtime sensors to existing silos is easily possible at any time.
We would like to thank Brückner Maschinenbau GmbH & Co. KG for the many years of cooperation.

Fibre Breakage Detection and Constant Diameter Measurement
When manufacturing fibres of any kind, it must be ensured that there are no faulty productions or breakages. This applies to glass fibres, synthetic fibres, threads as well as thinner wires. In the event of a breakage, this must be recognised immediately and the machine stopped. Consistent measurement of the diameter is crucial in order to identify quality defects and reject defective areas. Machine intervention is often required to prevent breakage, which would require re-threading.
The ODC1200 optical micrometer from Micro-Epsilon enables continuous diameter measurement and checks fibres and wires for breaks and constant diameter. Thanks to its high-quality glass optics and a robust, compact design, the optoCONTROL even fits into limited installation spaces. It is characterised by extremely fast measurements with a high cut-off frequency and offers a small and compact design.
