Problems solved by technology

In the manual winding machine or semi-automatic winding machine of the prior art, the feeding of the two electrode sheets is manually operated, and the winding process of the battery core is shown in Figure 1. They have a common disadvantage: due to the two poles The sheet feeding mechanism and the two diaphragm feeding mechanisms are located on the same side of the winding machine. When the worker feeds the positive and negative electrode sheets, the two electrode sheet feeding mechanisms are located on the same side of his body, and he will inevitably use the same hand to handle them. Positive and negative electrode sheets, which can easily lead to the problem of positive and negative cross-infection of the battery, thus affecting the quality and service life of lithium batteries

Abstract

The invention relates to a Li-ion battery coiling core up-coiler, comprising two pole-piece feeding mechanisms (33, 34), two diaphragm feeding mechanisms (35, 36), a coiling switchover center (80) and a diaphragm cutting knife (60) and as well as two press blocks (30, 31). The coiling switchover center (80) comprises a coiling motor (81), two coiling pins (40, 41), a coiling switchover body (82) and a switchover drive mechanism (83); the first diaphragm feeding mechanism (35) is arranged at the upper end of the up-coiler, and two pole-piece feeding mechanisms (35, 36) are arranged along the first diaphragm (10) on the left side and the right side of the coiling switchover center (80); the two coiling pins (40, 41) are vertically arranged in parallel from left to right before the pins are put through; the diaphragm cutting knife (60) is driven by the drive mechanism to move horizontally; the two press blocks (30, 31) are arranged on the right and left side by side, and the two press blocks are driven by the respective drive mechanisms to make horizontal movement. When coiling a battery coiling core, cross contamination of the anode and cathode can be avoided effectively, and the quality and service life of the battery can be improved.

Description

technical field [0001] The invention relates to equipment for manufacturing secondary batteries, in particular to a winding machine for winding lithium ion battery cores. Background technique [0002] The quality of lithium-ion battery winding core directly affects the safety, consistency and service life of lithium-ion batteries, so lithium-ion battery winding machines play a very important role in ensuring battery quality. Battery core winding machines include: manual winding machines, semi-automatic winding machines and fully automatic winding machines. The winding process of the automatic winding machine, such as the upper diaphragm, the upper pole piece and the termination tape, are all continuously rolled and fed. This equipment has high efficiency, but the cost is also high, and the requirements for the pole piece are also very high. In order to save costs, domestic lithium-ion battery manufacturers generally use manual winding machines or semi-automatic winding mach...
