Problems solved by technology

[0002] When the square winding needle of the existing pole piece winding equipment is winding the pole piece, the linear speed of the pole piece tends to fluctuate greatly, which leads to problems such as powder drop in the quality of the wound battery core
Although there are currently some devices that compensate the linear velocity of the pole pieces, the compensation effect is not very good, which leads to some problems in the manufactured cells.

Abstract

The invention discloses a pole piece winding method. A needle winding servo motor is used to control the square winding needle according to the winding needle electronic cam curve; the winding needle electronic cam curve is obtained by the following algorithm: if i≤N, then If i>N, then.

Description

【Technical field】 [0001] The invention relates to a pole piece winding method. 【Background technique】 [0002] When the square needle of the existing pole piece winding equipment is winding the pole piece, the linear speed of the pole piece is prone to large fluctuations, which leads to problems such as powder drop in the quality of the wound battery core. Although there are currently some devices that compensate the linear velocity of the pole piece, the compensation effect is not very good, resulting in certain problems in the manufactured cells. 【Content of invention】 [0003] In order to overcome the problems in the prior art, the present invention provides a pole piece winding method to increase the speed of winding the battery core on the basis of ensuring the quality of the battery core obtained by winding. [0004] A pole piece winding method, using a winding needle servo motor to control the square winding needle according to the winding needle electronic cam cur...
