Presence Check for Screws and Nuts via Laser Distance Sensors Triangulation
In the automotive industry, metal or plastic components are often fixed to larger body parts with screws and nuts. To check whether nuts and screws are present and in the correct position after the robot-controlled screwing process, a laser distance sensor triangulation is installed above the component. With its fine light spot, it checks whether the small nuts and screws have been correctly positioned and screwed in. Its high accuracy means that even the smallest, darkest and most reflective objects can be reliably detected against any background.

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.

Copy Counting for Printed Products via Jump Detection with Triangulation Laser Distance Sensors
In the printing industry, newspapers and magazines are conveyed on conveyor belts in what is known as a shingle stream, i.e. overlapping. The copies must be counted so that the downstream packaging unit can process the exact quantity. Since they lie on top of each other and vary in thickness, detection must take place independently of the absolute distance to the sensor. A triangulation laser sensor mounted above the conveyor belt reliably detects the units thanks to the integrated jump detection function. In this operating mode, the sensor reacts to measured value jumps on the folds.

Detection of Thin Wafer Slices Laser Distance Sensors Triangulation in Production Systems
During the production of multi-layer cookies, individual wafer slices are transported on conveyor belts before they are coated with cream and processed into a stacked cookie. Laser distance sensor triangulation precisely detects the position of the wafer slices and thus controls the material flow of the system. Thanks to the integrated jump detection, the wafer-thin slices, just one millimeter high, can also be reliably detected on the slightly fluctuating conveyor belt. Even if the sensor is misaligned, it does not need to be re-taught in, as it reacts to the jump.

Presence Check of HDF Boards for Positioning on a Conveyor Belt by Laser Distance Sensor Triangulation
High-density fibreboards (HDF boards) with a thickness of just a few millimeters are used in furniture production. These are transported on conveyor belts and fed to the various processing steps. A laser distance sensor triangulation is mounted above the conveyor line to detect the thin boards precisely and position them. Thanks to the integrated jump detection, the sensors reliably detect the boards even if the conveyor belt is uneven. This ensures that the boards are precisely positioned and can be fed to the next processing step.
