Double Layer Detection of Sheet Metal and Body Parts by Laser Distance Sensors Triangulation
In the automotive industry, sheet metal parts are taken from a stock by a robot gripper and fed to the welding robot. Several sheets can stick together due to adherent oil, wedging of the sheets or magnetic charge. To ensure that only one sheet is gripped per assembly process, two laser distance sensors triangulation are mounted at opposite positions. The sensors measure the distance to the sheet and then calculate the sheet thickness via a difference calculation. If this result is greater than that of an individual sheet, a signal is output.

Presence Check of Seals with Laser Distance Sensors Triangulation
When assembling drive systems in the automotive industry, seals are inserted before a cover is mounted on the drive. The laser distance sensors triangulation with integrated intensity evaluation record both the distance and the received intensity between the sensor and seal. The measured distance is used to check whether only a single seal is present. The thin white seal on the glossy cap is detected by the drive system based on the intensity. The measuring function guarantees reliable part control.

Double Layer Control of Coffee Capsules Before Filling by Laser Distance Sensors Triangulation
When producing capsules for coffee machines, it must be ensured that only one capsule at a time is inserted into the trays of the multi-lane conveyor belt during filling. For this purpose, one precise laser distance sensor triangulation is used per track, which recognizes whether one or more capsules are positioned on top of each other. Eight sensors simultaneously check the eight tracks of the conveyor belt. Due to their material independence, CMOS sensors reliably switch to capsules of a wide range of colors – even on metallic, shiny capsules.
