Problems solved by technology

The guide plate body of the electrode sheet guide plate structure of the lithium battery core winding machine in the prior art is made of metal, and the electrode sheet rubs against the guide plate body during the conveying process, resulting in the metal chips being scraped off the guide plate body, and these metal chips are scraped off by the electrode sheet. And get involved in the lithium battery winding core, causing the self-discharge phenomenon of the lithium battery to increase, the battery to heat up or even an internal short circuit

Abstract

The present invention provides an electrode plate guide structure of a lithium battery rolling core winder, including an elongated guide plate body (10) which cross section shows character ''concave'' and an adjusting mechanism (20) connected to the winder frame, the center of the guide plate body is a channel for transferring the electrode plate, two sides of the guide plate are side jambs (12), characterized in that the whole guide plate body is made of non-conductor hard material, or the channel (11) surface or internal surfaces of two side jambs are attached or inlayed with a non-conductor hard material layer (18). Compared with the prior art, the electrode plate guide structure of the lithium battery rolling core winder effectively avoids the metal particles winded in the battery roll core of the prior art, reducing the battery heating, improving the self discharge resistance performance.

Description

technical field [0001] The invention relates to equipment accessories for manufacturing secondary batteries, in particular to an electrode piece guide plate structure of a lithium-ion battery core winding machine. Background technique [0002] The electrode sheet guide plate structure of the lithium battery core winding machine includes a guide plate body and an adjustment mechanism connected to the winding frame. The guide plate body is provided with guide grooves for conveying electrode sheets. The guide plate body of the electrode sheet guide plate structure of the lithium battery core winding machine in the prior art is made of metal, and the electrode sheet rubs against the guide plate body during the conveying process, resulting in the metal chips being scraped off the guide plate body, and these metal chips are scraped off by the electrode sheet. And get involved in the lithium battery core, causing the self-discharge phenomenon of the lithium battery to increase, the...
