Embodiment Construction

[0014] The preferred embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings of this specification.

[0015] see Figure 1 to Figure 31 , the present invention takes the winding of the first diaphragm G1, the first pole piece J1, the second diaphragm G2 and the second pole piece J2 of a lithium battery cell as an example, and proposes a winding device 100, which generally includes: a rotating large plate 18, three rolling needles 19 evenly distributed on the rotating large disk 18, and the auxiliary mechanism matched with the rotating large disk 18 and the winding needle 19 thereof. Wherein, the coiling needle 19 on the upper left corresponds to the winding station; the coiling needle 19 on the lower left corresponds to the remnant coiling station; the coiling needle 19 on the right corresponds to the unloading station. There are three fixed rollers 185 evenly distributed on the central portion of the rotati...

Abstract

A winding device for winding a lithium battery cell comprises a rotating large disk, a plurality of winding needles uniformly distributed on the rotating large disk, and an auxiliary mechanism cooperating with the rotating large disk and the winding needles. The auxiliary mechanism includes a cutting diaphragm unit located at the lower portion of a winding needle at a winding station and a pressure diaphragm unit located at the lower portion of the cutting diaphragm unit, wherein the cutting diaphragm unit comprises a cutter for cutting a diaphragm to be wound and a motor use for driving traverse movement of the cutter, and the pressure diaphragm unit includes a pressure roller for pressing the diaphragm to be wound and a motor for driving the pressure roller to move laterally. The precision is high, the stability is good, and the processing efficiency is greatly improved.

Description

technical field [0001] The invention relates to a winding device, in particular to an auxiliary mechanism of the winding device. Background technique [0002] Existing winding equipment usually includes a rotating large disk, three winding needles evenly arranged on three stations on the rotating large disk, and several auxiliary mechanisms. Among them, the three stations correspond to the winding station, the residual coil station and the unloading station. The auxiliary mechanism is used to cooperate with the rotating large plate and the winding needle to realize the corresponding functions, such as: positioning and cutting the diaphragm, and correcting the deviation of the pole piece. The existing auxiliary mechanism is generally based on the air circuit system, and the cylinder is used as the power element to realize the driving of the pressure roller, the cutter and the correction roller. There are some defects in the use of cylinder drive: the precision is not high e...
