1. Qianjiang qjr6-3 robot is used in this project. The robot has a load of 6kg, repetitive positioning accuracy of ± 0.05mm, arm span of 2001mm, and large working space. It is suitable for welding of large and large products. It can be used with Panasonic, fornix, Lincoln, kenby, Altai, meggite and other main stream welding machines, which can realize the welding of carbon steel, stainless steel, aluminum alloy and other materials;

2. The dual axis U-shaped positioner and gun cleaning station used in the project are controlled by the robot control cabinet. During the welding process, the robot and positioner can move coordinately without the need for the positioner to be driven by the control cabinet, which saves space;

3. The displacement function of positioner can make the position of welding seam that robot can’t reach or is not conducive to welding. In the welding process, it can make the workpiece to be welded obtain the ideal welding position. The welding gun can weld with the best welding posture, which expands the welding range of robot and ensures the welding quality and appearance requirements;

4. After the welding of each product, the torch cleaning station can automatically clean the welding slag of the welding gun, so as to protect the nozzle and conductive nozzle of the welding gun, prolong the service life of the welding gun, save the cost of consumables, maintain good welding quality and improve the welding efficiency.
