Appearance and welding quality

After welding, the weld shall be free of defects such as pits, broken welds, misalignment, and explosion points, and the weld shall be smooth and flat, which will not cause serious deformation of the shell. There is no welding slag in the shell after welding, and the laser does not burn the diaphragm and high-temperature tape inside the shell

Description

Remark

1. 

Manual feeding, taking the sealing surface of the electric core as the benchmark, lift up from the bottom of the electric core to ensure the consistency of the upper benchmark; The long side cylinder is locked, the short side cylinder is locked, the upper reference cylinder is unlocked, and the lower end of the fixture adopts a spring positioning mechanism. The spring is elastically deformed to ensure that the cell shell is not scratched during precise positioning;

2. 

Pre weld the cover plate and shell first, and then fully weld after fixing the position.

3. 

The clamping part is not in overall contact with the cell, and the middle is hollowed out to prevent excessive extrusion pressure on the cell; Manual blanking: when the battery moves to blanking, the battery cylinder unlocks, the battery cell pops up, and the material is taken manually. The short side is clamped by a rotating cylinder, and the electric core is placed and taken from the side, which is convenient to operate.

Remark

1.

The laser output head is driven by a three-axis high-precision mechanical module to ensure the accuracy of the hardware; Using high-precision algorithm and controller, accurate laser excitation power and path; Press the assembly mechanism up before welding, and then fully weld the top cover to ensure the product qualification rate; The exhaust pipe and filter shall be made of fire-retardant materials, and the connecting parts shall be connected with steel rings.

Description

Remark

The upper cover of the equipment is composed of sheet metal and Tan acrylic panels, and safety gratings are installed to ensure the safety of operators. The human-machine interface of the equipment is designed according to the existing structure of the company, and the welding parameters are visual and traceable.
