[0030] Working principle: When in use, the first motor 21 drives the first lead screw 22 to rotate, causing the two sliding brackets 23 to move closer or further apart, thereby adjusting the distance between the first fixing components 4 and fixing rear panels of different sizes. Rotating the first threaded rod 42 causes the first fixing plate 43 to press and fix the rear panel, placing the rear panel bracket inside the U-shaped frame 10. Rotating the second threaded rod 112 causes the second fixing plate 113 to press and fix the rear panel bracket. The electric telescopic rod 91 drives the slider 93 to extend through the mounting frame 92. The U-shaped rod 94 on the side of the U-shaped frame 10 slides inside the slider 93. By changing the extension distance of the electric telescopic rod 91, the angle of the U-shaped frame 10 is changed, making it suitable for welding rear panel brackets at different angles. The second motor 71 drives the second lead screw 72 to rotate, causing the lifting frame 73 to lower the fixed rear panel bracket to fit against the rear panel. Two welding robots 5 then weld the rear panel and the rear panel bracket. This utility model has the advantages of being easy to use and having good performance.
