An Aluminum Coil End Face Welding System Based on Point Line Laser

Abstract

The present invention proposes an aluminum coil end face welding system based on a point-line laser. The welding system includes a welding robot including a central control module, a transport control module and a robot arm; the robot arm drives the welding assembly for welding; the welding assembly includes a welding torch head, Laser control module, camera component and image processing module; the laser control module includes a point laser component and a line laser component; when welding the end face of the aluminum coil, the welding robot moves to the welding station, and the robot arm first uses the point laser component to weld the aluminum coil Scanning and positioning, and then scanning the two sides of the end surface of the aluminum coil and the two sides of the core with the line laser component to form a line laser feedback signal, and taking pictures of the end surface of the aluminum coil with the camera component, and the image processing module recognizes the line laser feedback signal and the photo of the camera component , using the identified available welding positions as welding points for welding; the available welding positions include the staggered layer of the end face of the aluminum coil and the connection position of the smooth layer; the invention can quickly and conveniently weld the end face of the aluminum coil.

Description

technical field [0001] The invention relates to the technical field of aluminum material processing, in particular to a point-line laser-based aluminum coil end face welding system. Background technique [0002] After heat treatment, the aluminum coil needs aging treatment. The aging treatment needs to weld the head and tail of the aluminum coil. If necessary, some other positions need to be welded to fix the shape of the aluminum coil. In the prior art, the search for solder joints is either done manually or through traditional visual recognition schemes. However, manually relying on experience to find solder joints, its accuracy cannot be controlled, and it does not meet the needs of automated factories. Traditional visual recognition solutions often use one-time imaging technology to identify the outline of aluminum coils and the image details are obviously insufficient, which is difficult to meet production needs.
