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 and equipment. The equipment includes a pole piece unwinding assembly, a pole piece winding assembly, and a horizontal electronic cam assembly. The horizontal electronic cam assembly includes a servo motor, a coupling, a screw nut, Lead screw, connecting block, guide rod, guide rod holder, horizontal pole piece roller and pole piece feeding assembly, the output end of the servo motor is connected with the lead screw through a coupling, and the pole piece feeding assembly is used to gather the first pole The first pole piece unrolled by the sheet unwinding assembly and the second pole piece unrolled by the second pole piece The motor is used to drive the horizontal pole piece roller to move in the horizontal direction, and the horizontal pole piece roller is used to apply a horizontal compensation speed to the surface of the pole piece located between the pole piece unwinding assembly and the pole piece winding assembly.

Description

【Technical field】 [0001] The invention relates to a pole piece winding method and equipment. 【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 and equipment, so as to increase the speed of winding the electric core on the basis of ensuring the quality of the wound electric core. [0004] A pole piece winding device, including a pole piece unwinding assembly and a pole piece winding assembly, and also includes a ho...
