[0026] During the conveying operation, the conveying motor 104 is powered on to drive one of the sprockets to rotate, and one of the sprockets drives the other sprockets to rotate through the chain, thereby driving multiple conveying rollers 103 to rotate. The conveying rollers 103 can convey the energy storage battery products that need to be pre-welded to the other side.

[0027] The guide assembly 2 is mounted on a support column 203 on the conveyor frame 101. A guide screw 201 is provided on the upper portion of the support column 203.

Since the output end of the electric push rod 306 is fixedly connected to the lifting plate frame 303, when the output end of the electric push rod 306 is extended, the electric push rod 306 drives the control plate 305 to move outward, thereby driving the control rod 308 to move, and the control rod 308 drives the positioning slide 301 to move outward. Conversely, the positioning slide 301 can be controlled to move inward.

Since the output end of the electric push rod 306 is fixedly connected to the lifting plate frame 303, when the output end of the electric push rod 306 is extended, the electric push rod 306 drives the control plate 305 to move outward, thereby driving the control rod 308 to move, and the control rod 308 drives the positioning slide 301 to move outward. Conversely, the positioning slide 301 can be controlled to move inward; the moving positioning slide 301 can drive the sliding welding seat 401 to slide synchronously on the slide rail 102 to ensure that the positions of the welding head 403 and the welding channel correspond to each other, thereby improving the welding accuracy. Then the welding push rod 404 is energized and works to drive the welding movable plate 405, and the welding movable plate 405 drives the welding head 403 to pass through the welding channel of the positioning slide 301 to pre-weld the connection between the upper cover and the aluminum shell of the energy storage battery product, thereby facilitating subsequent continuous welding operations.
