Product Details

Laser Welding Machine for Prismatic Battery Top Cover Plate Welding

1、Equipment Overview

This equipment is used for sealing welding and liquid injection hole welding of prismatic battery top cover. It is a semi-automatic equipment. The top cover of the incoming material has been manually buckled into the aluminum shell. Taking the sealing surface of the battery as the upper benchmark, it is positioned from the top of the bottom plate of the cell. After laser welding, it is manually inspected and judged. This equipment can quickly change the fixture and is suitable for welding of various models of products.

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

5、Configuration of main components

Equipment composition:

1. Top cover welding battery clamp part

SN	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.

2.Three axis welding platform

SN	Description	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.
