[0002] Shelf beams (including rear rails, support beams, etc.) are all welded manually or by a combination of automatic and manual welding. Automatic welding can only weld certain types of column clips, and products with hanging ears and U-shaped bent plates require manual welding. Manual welding has the problems of high cost, low efficiency, and unsightly weld appearance. Automatic welding has a truss structure, and the welding gun has low degrees of freedom and cannot swing, resulting in problems such as burn-through and insufficient weld coverage.

The main problem is: the existing equipment adopts a horizontal rotation design, and the long rods are long, and it is difficult to have such space for rotation in production practice. In addition, the load-bearing of the existing equipment generally adopts the middle turntable to bear the load, which may cause instability for the long rods, and the reliability and accuracy of the transmission method are also difficult to guarantee. According to specific needs, the double-station automatic welding equipment is optimized and improved to realize the automatic welding of shelf beams. Utility Model Content
