Description

technical field [0001] The invention relates to the technical field of polymer lithium battery manufacturing equipment, in particular to a polymer lithium battery formation, composition, and capacity integrated machine. Background technique [0002] Traditional liquid lithium-ion polymer batteries adopt a step-by-step process of formation and volume separation. The disadvantage is that it needs to be clamped down after formation, and clamped again before volume separation. The entire lower clamp and upper clamp are manually operated. This kind of process and operation method has the following disadvantages: 1. It needs a lot of labor-intensive labor, and the labor cost is high; 2. The labor intensity of manual clamping and clamping is high; 3. The efficiency of manual operation is low; 4. Manual operation, its upper clamping and clamping The clamping process depends on the operator's operating experience and proficiency, the quality is not stable, and it is easy to produce a...

[0002] The traditional liquid lithium-ion polymer battery adopts the process of formation and capacity separation step by step. The disadvantage is that it needs to be clamped down after formation, and clamped again before capacity separation. The entire lower clamp and upper clamp are manually operated.

This kind of process and operation method has the following disadvantages: 1. It needs a lot of labor-intensive labor, and the labor cost is high; 2. The labor intensity of manual clamping and clamping is high; 3. The efficiency of manual operation is low; 4. Manual operation, its upper clamping and clamping The clamping process depends on the operator's operating experience and proficiency, the quality is stable and poor, and it is easy to produce a large number of defective products

[0003] The existing chemical formation and volume separation equipment can only process a single process, which is a stand-alone production mode, that is, chemical formation requires chemical formation equipment, and volume separation requires volume separation equipment

During the production of this stand-alone production mode, the formation and volumetric equipment occupy a large area, and the semi-finished products produced by each equipment need to be piled up on site to wait for turnover, resulting in the occupation of valuable space in the workshop and greatly affecting the production environment; On the other hand, the semi-finished products produced by each equipment need to be manually transferred to another equipment. The labor cost is high, and the efficiency is low, and defective products are prone to occur. At the same time, there are inevitable human factors losses.
