Embodiment

[0084] Such as figure 1 As shown, a laser sensor-based welding seam automatic tracking test device includes: a welding robot module, a laser sensor module, a welding module and a feature detection module.

[0085] Such as figure 2 As shown, the laser sensor module: MTI 2d stripe laser sensor, sensor mounting bracket, light baffle, and mounting plate together constitute the entire sensor module, which is connected to the end flange of the robot through the sensor mounting bracket.

[0086] Welding module: LORCH welding machine, wire feeding structure and welding torch form the whole welding module, which controls the arc starting and feeding of welding wire.

[0087] Feature detection module: Industrial computer and welding control software together constitute the control module of the whole system. The weld feature point detection algorithm of the control software uses wavelet transform and least square method to process data, extract the feature points of the weld and obt...

Abstract

The invention discloses a laser sensor-based welding seam automatic tracking test device and a test method thereof. The device includes a welding robot module, a laser sensor module, a welding module and a feature detection module; an RB08 welding robot produced by the Guangzhou numerical control company is adopted as the welding robot module; the laser sensor module is composed of an MTI 2D laser sensor, a light barrier and an installation support, wherein the MTI 2D laser sensor is connected with a tail end flange of a robot body through the installation support; the welding module includes a welding machine, a wire feeding structure and a welding gun; the feature detection module includes a controller and a detection unit; the laser sensor module can detect two-dimensional data of a weld groove; the detection unit selects the type of a welding seam and calls a feature recognition algorithm corresponding to the type of the welding seam, and returns a welding seam center to a robot controller cabinet; and the robot body drives the welding gun to align with the welding seam center in real time. With the laser sensor-based welding seam automatic tracking test device and the test method thereof of the invention adopted, automatic tracking of welding seams can be realized, and welding quality can be ensured.

Description

technical field [0001] The invention belongs to the field of welding technology, and in particular relates to a laser sensor-based welding seam automatic tracking test device and a testing method thereof. The invention is suitable for application fields requiring welding robots and laser technology for automatic welding seam tracking. Background technique [0002] The welding environment is very harsh, usually accompanied by smoke, high temperature, spatter and arc light interference, which greatly reduces the effect and work efficiency of manual welding. At present, robot welding has been widely used in many fields such as automobiles, construction machinery, and container production at home and abroad. However, the current welding robots are all typical "teaching and reproduction" modes. "Teaching programming" refers to completing the programming of the program in the following way: by manually guiding the robot end effector (such as: welding gun) to make the robot complet...
