Problems solved by technology

[0002] Body welding is an indispensable connection method in the automobile manufacturing process. During the welding process, due to the deviation of the workpiece group, electrode wear and other factors, poor solder joints may be caused, such as virtual welding, burrs, deep indentation, air holes, spatter, etc. There are as many as 4,000 solder joints and weld seams on the body-in-white of a vehicle. In related technologies, manual inspection of solder joints or weld seams is mostly used, which is labor-intensive, low-efficiency, and high-cost. There is room for improvement.

Abstract

The invention discloses a welding quality detection device. The welding quality detection device comprises a control unit, a positioning unit, a detection unit and a moving unit, wherein the positioning unit is connected with the control unit, and is used for transmitting positional information of a welding part to the control unit; the detection unit is used for detecting the welding information of the welding part; the positioning unit and the detection unit are arranged on the moving unit, and the moving unit is connected with the control unit so as to enable the detection unit to move to a detection position of the welding part according to the positional information, wherein the control unit is set to judge the welding quality of the welding part according to the positional information and the welding information. According to the welding quality detection device disclosed by the invention, automation and intellectualization of welding quality detection can be realized, the labor intensity is reduced, the detection efficiency is high, the influence of human factors is reduced, the stability and precision of detection are greatly promoted, and the detection cost is low.

Description

technical field [0001] The invention belongs to the technical field of vehicle manufacturing, and in particular relates to a welding quality detection device. Background technique [0002] Body welding is an indispensable connection method in the automobile manufacturing process. During the welding process, due to the deviation of the workpiece group, electrode wear and other factors, poor solder joints may be caused, such as virtual welding, burrs, deep indentation, air holes, spatter, etc. There are as many as 4,000 solder joints and welds on the body-in-white of a vehicle. In related technologies, manual inspection of solder joints or welds is mostly used, which is labor-intensive, low-efficiency, and high-cost, and there is room for improvement. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. Therefore, an object of the present invention is to provide an efficient wel...
