Autonomous optical angle measurement for press brakes

Autonomous Optical Angle Measurement for Press Brakes

The OEM Laser Profilers for checking the angular accuracy in sheet metal bending press brakes . The VCnano3D-Z 3D line sensors reach measuring rates up to 400 Hz and a typical accuracy of <±0.1°. They can be directly connected to the machine's PLC for real-time control of the contact pressure, in order to boost productivity and efficiency of press brakes. Delem, a leading manufacturer of controls for sheet metal machines, has already completed the integration of the laser profilers in its controllers.

Angle measurement in sheet metal bending: Measurement of the bending angle and real time process adjustment

The 3D laser triangulation systems operate autonomously, without an external computer. This provides customers with an extremely robust, low-maintenance, and cost-effective solution. Featuring a compact IP67 housing and a large field of view, VCnano3D-Z sensors are easy to integrate and can be used with different dies without any conversion or adjustment. The blue high-performance laser and Vision Components' proprietary ambient light suppression technology ensure reliable detection on shiny and reflective surfaces, for example when bending stainless steel, copper, brass, and foiled materials. The embedded vision system's 3D analysis is also designed to correctly detect perforated metal, checkered plate metal, and brushed aluminum.

Few profile points are sufficient for precise angle measurement even with short sheet metal pieces. The embedded vision pioneer Vision Components, which celebrates its 25th anniversary in 2021, ensures the long-term availability of its products and supports machine builders and manufacturers of inspection systems in their application integration.
