[0043] Working principle of the utility model: before the process of press-fitting and welding the lower connecting plate, the lower connecting plate is first placed on the top of the workbench 1 in turn, and the lower connecting plate is driven by the conveying mechanism 20 to be conveyed at a uniform speed. When the lower connecting plate passes through the bottom of the bracket 2, the first visual detection camera 3 observes the left and right angles of the lower connecting plate. When the lower connecting plate does not remain vertically vertical on the top of the workbench 1, the first motor 5 inside the two fixing rings 4 drives the top block 6 and the sweeping piece 7 to rotate, and the two sweeping pieces 7 move the lower connecting plate to the left and right angles so that the lower connecting plate can remain vertical in the vertical direction.

The two balancing push blocks 16 drive the motor 17 and the clamping plate 18 at the bottom to clamp the passing lower connecting plate. Then the two telescopic rods 10 drive the cross beam 12 to rise upward, and then the two motors 17 drive the clamping plate 18 to flip the front and back of the lower connecting plate, so that the current lower connecting plate maintains the opposite direction of the previous lower connecting plate. The adjusted lower connecting plate slides stably onto the bottom pressure plate 24 inside the connecting frame 22 through the inclined base 21. After the two lower connecting plates enter the opening of the connecting frame 22, the first hydraulic rod 23 drives the bottom pressure plate 24 to rise upward, and the second hydraulic rod 25 drives the top pressure plate 26 to press downward, press the two lower connecting plates together, and finally perform subsequent welding.
