A laser welding calibration device based on optical sensors

Abstract

The utility model provides a kind of laser welding calibration device based on optical sensor, it is related to welding equipment technical field, including workbench, welding controller, laser welding torch and calibration camera;Workbench is equipped with horizontal moving sliding table and horizontal moving assembly, and welding table and longitudinal moving assembly are slidably equipped on horizontal moving sliding table, and welding workpiece is clamped on welding table, and welding torch is installed above welding table by fixing frame.The beneficial effects of the utility model are as follows: the laser welding calibration device can control welding workpiece on welding table to move in horizontal plane according to predetermined trajectory relative to welding torch when welding, so that welding torch welds workpiece according to predetermined trajectory, and automatic welding of workpiece is realized.And calibration camera can real-time shoot actual weld, compare error between actual weld and predetermined weld by image analysis module, and feedback error information to welding controller, so that welding controller calibrates welding error, and welding precision is improved.
