Abstract

The invention provides a winding needle assembly and a winding device. The winding needle assembly comprises two clamping pins, a driving unit and a winding unit. The driving unit is connected with the winding unit and the two clamping pins. The driving unit can move the winding unit in order to deform the winding unit into a cylinder. The driving unit can also move the winding unit in order to deform the winding unit into an elliptical cylinder. The winding unit is configured to wind a material strip. When the winding unit is deformed into the elliptical cylinder, the two clamping pins get away from each other to release the material strip. When the winding unit is deformed into the cylinder, the two clamping pins get close to each other to clamp the material strip. Thus, the winding needle assembly provided by the invention can not only produce a high-quality battery cell for a square battery, but also can be prevented from rotating by complex programming, thereby greatly reducing development time and cost. The winding device includes the winding needle assembly, and thus has all technical features and beneficial effects of the winding needle assembly.

Description

technical field [0001] The invention belongs to the technical field of battery production, and more specifically relates to a winding needle assembly and a winding device. Background technique [0002] In the battery manufacturing process, materials such as separators and pole pieces (that is, strips) need to be wound into batteries, and then the batteries are put into the battery case to form a battery. In the process of winding the material tape into a battery cell, the equipment used is the winding device. The winding device includes a winding needle. The winding needle is a component used to fix the material tape and facilitate the winding of the material tape. [0003] At present, for square batteries, the coiling needles used are all flat or elliptical, so that the rolled tape can naturally be used as the battery cell of the square battery, but the programming control is very high in order to roll the product, because the tape The direction of needle entry is fixed. I...
