Product Description

Laser Welding Machine for Prismatic Cell Manufacturing

 
    

1,Equipment Overview
1. Equipment introduction:
This equipment is used for soft connection welding of prismatic battery top cover, which is a semi-automatic equipment. Manually release and take the cover plate and core of the electric core, clamp the fixture cylinder on the welding surface, and the welding form is laser swing weld. After laser welding, manually detect and judge. This equipment can quickly change the fixture and is suitable for welding of various models of products.

1. Product accuracy

SN	Item	Standard
	Welding flanging width	<0.3mm
	Weld penetration and width	Effective penetration:0.5~1.4mm,Effective melting width:0.8~1.5mm
	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

 

5,Configuration of main components
  1. Soft connection fixture part

 

SN	Description	Spec
1.	Manually load the material, place the products in the positioning fixture in turn, install the anti welding slag shield outside the electric core to prevent the welding slag from splashing onto the surface of the battery, and press it back and forth with the cylinder to prevent scratching the battery
2.	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 battery 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; Anti flame retardant materials are used for the exhaust pipe and filter, and steel rings are used for the connection parts.

 

3.Frame cover and man-machine interface

SN	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.

5,Equipment capacity requirements

SN	Item	Index	Remark
	Time efficiency = Actual operation time: load time - planned downtime (failure, material switching) Load time: production hours - planned downtime Production hours: normal working hours Planned downtime: morning and evening, rest, spot check, cleaning, etc	≥99.00%
2.	Performance improvement=  Theoretical tempo: theoretical production time of a single product	100%
	Product qualification rate=  Fixed loss: tape splicing, coil changing, etc	≥99.50%
4	CMK Equipment capacity index CMK index only considers short-term dispersion and emphasizes the influence of equipment factors on product quality. Test requirements: the extracted data is continuous; It is assumed that the operator, measuring tools and raw materials are not affected; Only consider the influence of a single factor of the equipment. (that is, the operator must be skilled and competent; the measuring tools must meet the requirements and have been calibrated; the same batch of materials; and the inspectors meet the requirements.) Generally, 10 groups of 100 samples are sampled for measurement within about one hour after the production of the machine is stable.	≥1.67
