[0018] 1.

The cover placement guide rail assembly is used for fitting and fixing, and the cover placement guide rail assembly applies pressure to the welding contact surface of the cover and the shell, so that the cover is stably fitted to the welding end of the shell, rather than rigidly clamping the entire workpiece. This contact surface positioning mode can avoid the stress influence on the overall workpiece when using the unified clamping structure, ensure the relative position of the cover and the shell is stable during welding, and reduce the deformation problem caused by uneven clamping force from the root.

Compared with the existing technology, this new energy battery shell welding tool realizes the full process automation of welding shell from positioning, welding to cutting through the linkage of electric push rod, support baffle and snap mechanism, reduces manual operation errors and improves production efficiency. The design of two sets of welding stations can better support assembly line operation, further shorten the cycle time, and use double electric support baffles and side baffles to form a multi-point support structure, which forms a rigid constraint on the welded shell during the welding process and can effectively suppress the influence of welding thermal deformation on the shell. At the same time, the sliding plate and slide rail cooperate with each other to ensure the linear motion accuracy of the welded shell when adjusting the position, reduce welding defects caused by positioning deviation, and use the snap-on reset mechanism to ensure the consistency of the sliding plate returning to the initial position each time, providing a stable reference for the positioning of subsequent workpieces.

[0020] 3. Compared with the existing technology, this new energy battery shell welding tool uses an electric push rod to directly drive the sliding plate to carry the welding shell to move, and the pushing path is connected to the conveyor belt, which reduces the operator's normal handling and welding repetition time. The snap-on reset design uses the push rod to reset and synchronously drives the sliding plate to return, shortening the idle time and shortening the cycle of a single workpiece. In addition, the layout of the two groups of welding stations can support parallel operations of loading, welding and unloading, which can optimize equipment utilization.
