Traditional welding processes usually use manual operation or semi-automated equipment, which has problems such as low efficiency, poor consistency, and many safety hazards. In particular, the welding of the bottom plate and the body of the thermos cup has high requirements for welding precision, temperature control, and workpiece positioning. Traditional methods are difficult to meet the needs of large-scale, high-quality production. In addition, the existing production lines often lack effective coordination in the workpiece conveying, positioning, welding, and unloading processes, resulting in low production efficiency and more manual intervention, which increases production costs and operational risks.

The safety guardrail 2 is provided with openings that pass through both ends, and the conveyor line 1 is provided through the openings, with both ends extending to the safety area to form a loading end and a unloading end.

[0037] Both the loading and unloading ends are staffed by designated personnel.

[0038] Furthermore, the energy storage welding machine 3 is located on the side of the conveyor line 1 and is used to weld the workpiece;

[0039] The energy storage welding machine 3 includes:

[0040] The frame 31 has an extension frame 3101 at one end, and a turntable 3102 driven by a fifth motor 3103 is rotatably mounted on the extension frame 3101.
