Screen Printing Mesh Frame Height Detection with Laser Displacement Sensor

Industry pain points and demands

In screen printing machines used for photovoltaic applications, accurately detecting the height of the mesh frame is essential to maintain optimal squeegee pressure during the printing process. If the frame’s depth is insufficient, it may result in poor print quality or adhesion issues. Conversely, excessive depth can damage the mesh frame due to collisions.

The SD22-35 Point Laser Displacement Sensor by SinceVision provides precise height measurements, offering real-time feedback for process optimization. With a 20–50mm measurement range, 0.1% F.S. linearity, and a maximum sampling frequency of 3kHz, the sensor ensures consistent and reliable measurements. These capabilities help improve print accuracy and extend equipment lifespan.
