Problems solved by technology

[0003] The pole piece is the key component of the lithium-ion battery. The manufacturing process of the pole piece is as follows: first, use a coating machine to coat the electrode slurry on the surface of the current collector, dry the coated electrode slurry to solidify on the surface of the current collector, and then use The pole piece is rolled by a roller press to obtain a pole piece with a compact structure. After the pole piece is processed, it needs to be wound up. The pole piece winding device in the prior art often has the following problems during use: the pole piece is When being wound up, its winding diameter changes fro

Abstract

The invention discloses pole piece winding equipment. The pole piece winding equipment comprises a support. The top of the support is provided with a first rack and a second rack located on the rightside of the first rack. The first rack is provided with pull rolls. The second rack is provided with a guide wheel, a first driving wheel, a second driving wheel, a tension detector and a cutting device from left to right in sequence. The top of the support is further provided with a winding device located on the right side of the cutting device. The winding device comprises an angle adjustable supporting rod arranged on the top of the support, a winding drum arranged at the top end of the supporting rod and a winding motor arranged on one side of the winding drum and connected with the winding drum. The winding drum is internally provided with a frequency converter. Thus, the pole piece winding equipment provided by the invention brings convenience to people for use.

Description

technical field [0001] The invention relates to the technical field of lithium ion battery manufacturing, in particular to a pole piece winding device. Background technique [0002] Lithium-ion battery is a new type of chemical power source. Due to its long cycle life, low self-discharge rate, no memory effect and low environmental pollution, it is widely used in communication equipment, mobile electronic equipment, power tools, electric toys and aircraft models. Be rapidly applied and popularized. [0003] The pole piece is the key component of the lithium-ion battery. The manufacturing process of the pole piece is as follows: first, use a coating machine to coat the electrode slurry on the surface of the current collector, dry the coated electrode slurry to solidify on the surface of the current collector, and then use The pole piece is rolled by a roller press to obtain a pole piece with a compact structure. After the pole piece is processed, it needs to be wound up. The...
