Abstract

The invention provides a device and method for detecting a filet weld welding trace based on laser ranging. The device for detecting the filet weld welding trace based on laser ranging adopts laser ranging and conducts autonomous locating and automatic welding on a weld joint of a filet weld piece. The device is characterized in that the device comprises a robot, a welding gun, a laser ranging sensor, a Beckhoff module, a main control computer and a robot controller, wherein the robot is provided with a robot body and a mechanical arm, the welding gun is arranged on the mechanical arm and used for welding the weld joint, and the laser ranging sensor is fixed to the end portion of the mechanical arm through a support and used for scanning the weld joint, and feature points of the weld joint on the spatial position are obtained; and the Beckhoff module is connected with the laser ranging sensor and used for collecting the feature points, and the positional information of the weld joint is obtained; and the main control computer is connected with the robot through the Ethernet network, and used for generating the welding sequence of the robot according to the positional information, and the robot controller is used for controlling the robot to conduct motion according to the welding sequence, so that welding is conducted on the weld joint.

Description

technical field [0001] The invention belongs to the field of welding, and in particular relates to a fillet weld welding track detection device and method based on laser ranging. Background technique [0002] The development of the manufacturing industry has made welding technology more and more important. Advanced welding technology can provide better efficiency and quality assurance for the manufacturing industry. However, manual welding can no longer meet the needs of modern production due to reasons such as long cycle, high labor intensity and harsh working environment. Welding robots are gradually replacing it and become the development trend in the welding field. [0003] In welded structures, fillet welds are one of the most common welds, especially in shipbuilding, where 80% of welds are fillet welds. At present, for the robot welding of fillet welds, most of them still adopt the traditional semi-automatic method of "teaching and reproduction". Some enterprises have...
