Coin Cell automatically produce Lithium battery assembly line

Introduction Coin Cell automatically produce

1.1 design concept and function description

Coin cell assembly line mainly realizes the automatic mass production of negative cover + negative sheet + diaphragm + Electrolyte liquid injection + positive sheet + positive shell + sealing complete set of process equipment, which improves the production efficiency of products while reducing labor costs, and the automation of equipment can ensure the consistency of product production and the improvement of qualified rate.

2. equipment performance parameters

Technical parameters of 2.1 equipment

• Production tempo: 35-40ppm/min (factors that cannot keep up with the tempo of manual pole pieces are not included in the acceptance items)
• Qualification rate of equipment: ≥99% (except for incoming materials)
• Equipment movement rate: ≥98%
• Bearing≤1t/m²;
• The shell cover shall not be reversed or jammed, and shall not cause scratches, abrasions, pits, bumps and other defects during the operation of the shell cover, and the diaphragm after punching shall not have burrs, gaps and other defects;
• The pole piece and diaphragm shall not be damaged during the operation of the equipment;
• The pole piece is located in the center of the shell cover, the initial concentricity is ≤0.2mm, and the shell cover shall not be "jumped" during operation;
• The diaphragm is bowl-shaped to avoid short circuit caused by pole piece deflection; (The incoming material method of the diaphragm is coil material, with a maximum outer diameter of 250mm and a width of 14mm-20mm)
• The liquid injection volume is 0 ~ 20uL, the liquid injection accuracy is ± 1uL, and the electrolyte shall not drip to the place outside the diaphragm;
• The sealing edge is 1.56±0.05mm high, the total height is 1.93±0.05mm, and the outer diameter is ≤9.47mm (the equipment is not customized, and the station mold is customized according to the size provided by the customer);
• After sealing, the product shall not leak liquid, except for the bad factors of spare parts (the leakage rate shall not be higher than that of our existing sealing products).
