Problems solved by technology

[0003] Most of the existing winding machines adopt the disk-type transposition winding method. The winding mechanism is arranged along the edge of the disk, and the position of the winding mechanism is switched by rotation. However, this method will cause many problems, for example, wear Auxiliary actions such as diaphragm and diaphragm cutting need to wait until the disc rotates to complete the station switch, resulting in a long auxiliary time, and the efficiency cannot be further improved. Moreover, frequent acceleration and deceleration or start and stop, the diaphragm is prone to large Tension fluctuations make the diaphragm easy to deviate, affecting the overall quality and winding efficiency of the winding core

[0071] see image 3 , image 3 It is a schematic flow chart of the cell winding method provided by the second embodiment of the present invention.

[0072] The battery winding method is applied to the battery winding device 10. The basic principle and technical effects of the battery winding device 10 are the same as those of the above-mentioned embodiments. For a brief description, the parts not mentioned in this embodiment are as follows: Reference may be made to the corresponding content in the foregoing embodiments.

[0073] The cell winding method includes:

[0074] Step S101: the winding mechanism 151 moves to the winding station 125 when the previous winding mechanism 151 leaves the winding station 125, cuts off the diaphragm 910 at the end of the winding core 900 on the previous winding mechanism 151, and receives and The membrane 910 is wound.

[0075] In this way, after the previous winding mechanism 151 winds to form the winding core 900 and leaves the winding s...

Abstract

The invention discloses a battery cell winding device and method, and relates to the technical field of battery cell winding. The battery cell winding device comprises a mounting platform, a conveyingassembly and a plurality of winding mechanisms, wherein an annular winding path is arranged on the mounting platform; the winding path is provided with a transposition section which is arranged alonga straight line and provided with a winding station at one end; the conveying assembly is mounted on the mounting platform; a diaphragm conveying device is used for conveying diaphragms and pole pieces to a winding station; the conveying direction of the conveying assembly and the extending direction of the end, away from the winding station, of a transposition section are the same in direction and collinear. Multiple winding mechanisms are movably connected to the mounting platform and can move along the winding path, and the winding mechanisms can enter the winding station when the previouswinding mechanism leaves the winding station along the transposition section, the diaphragm is cut at the tail end of the winding core, the diaphragm is received and wound, and the formed winding core leaves the winding station along the transposition section when the winding core is formed. The battery cell winding device and the battery cell winding method have the characteristics that the diaphragm can be continuously conveyed, and the winding efficiency and the winding quality are higher.

Description

technical field [0001] The present invention relates to the technical field of battery winding, in particular to a battery winding device and method. Background technique [0002] In the production process of lithium battery winding machine, the completion of a winding core includes normal winding actions and auxiliary actions. The auxiliary actions generally include actions such as diaphragm penetration, diaphragm cutting, and glue cutting. The auxiliary actions before and after normal winding are The main component of the entire winding process of the battery core, the length of the auxiliary time corresponding to the auxiliary action directly affects the efficiency of the entire equipment. [0003] Most of the existing winding machines adopt the disk-type transposition winding method. The winding mechanism is arranged along the edge of the disk, and the position of the winding mechanism is switched by rotation. However, this method will cause many problems, such as wear a...
