Louis@lithmachine.comLaboratory Prismatic Cell Laser Welding Machine For Top Case Welder
1、 Equipment Overview
This equipment is used for sealing welding and liquid injection hole welding of the top cover of square aluminum shell batteries, and is a semi-automatic equipment. The incoming top cover has been manually buckled into the aluminum shell. With the battery sealing surface as the upper benchmark, it is positioned from the top of the cell bottom plate. After laser welding, it is manually detected and judged. This device can quickly replace fixtures and is suitable for welding multiple models of products.

Appearance and welding quality |
After welding, the weld seam is free of defects such as pits, broken welds, misalignment, and bursting points, and the weld seam is smooth and flat, without causing serious deformation of the shell. After welding, there is no welding slag inside the shell, and the laser does not burn the internal diaphragm and high-temperature tape of the shell |
4、 Main component configuration
Equipment composition:
1. Top cover welding battery fixture part
|
No |
Description |
Parameter |
|
1 |
Manually load the material, using the sealing surface of the battery cell as the benchmark, and lift it up from the bottom of the battery cell to ensure consistency in the upper benchmark; The long side cylinder is locked, the short side cylinder is locked, and the upper reference cylinder is unlocked. The lower end of the fixture adopts a spring positioning mechanism, with elastic deformation of the spring to ensure that the battery cell shell is not scratched during precise positioning; |
|
|
2 |
Pre weld the cover plate and shell first, fix the position, and then fully weld. |
|
|
3 |
The clamping part is not in overall contact with the battery cell, and the middle is hollowed out to prevent excessive squeezing pressure on the battery cell; Manual cutting, the battery moves to the cutting position, the battery cylinder unlocks, the battery cell pops up, and the material is manually picked up. The short side is clamped by a rotating cylinder, and the battery cell is placed from the side for easy operation. |
|
2. Three axis welding platform part
|
No |
Description |
Parameter |
|
1 |
The laser output head is driven by a three-axis high-precision mechanical module to ensure hardware accuracy, and comes with its own; Adopting high-precision algorithms and controllers, precise laser excitation power and path; Before welding, press the installation mechanism and tighten the top cover before full welding to ensure the product qualification rate; The exhaust duct and filter are made of flame-retardant materials, and the connecting parts are connected with steel rings. |
|
3. Rack cover and human-machine interface part
|
No |
Description |
Parameter |
|
1 |
The upper cover of the equipment is composed of sheet metal and tawny acrylic panels, and Light curtain is installed to ensure the safety of operators. The man-machine interface of the equipment is designed according to the existing structure of the company, and the welding parameters are visible and traceable. |

CMK Equipment Capability Index The CMK index only considers short-term dispersion and emphasizes the impact of equipment factors on product quality. Test requirements: The extracted data is continuous; Assuming that the operator, measuring tools, and raw materials are not affected; Only consider the influence of a single device factor. (i.e., the operator must be proficient and competent; the measuring tools must meet the requirements and have been calibrated; the same batch of materials; and the inspection personnel must meet the requirements.) Generally, 10 sets of 100 samples are sampled for measurement within approximately one hour after the stable production of the machine.
