Vertical rubberizing device for full-automatic winder

Abstract

The invention provides a vertical rubberizing device for a full-automatic winder. The vertical rubberizing device comprises a bracket and a rubberizing wheel mechanism, wherein a rubber belt material winding frame, a rubber pass wheel set, a rubber conveying displacement mechanism, a rubber cutting mechanism and a rubber pressing mechanism are arranged in sequence on the bracket. The vertical rubberizing device has the beneficial effects that: a structure for directly applying rubber onto a rubber sticking wheel by conveying and pressing in a rubber belt loading way is adopted, so that the influence of rubber belt carrying error in an original device structure is eliminated, and the structure is simpler and reliable. Moreover, a rubber pressing wheel of the rubber pressing mechanism performs rubber dragging movement on a certain width by adhering to the side face of the rubber sticking wheel, so that the rubber pressing wheel is separated from a rubber belt in a flexible rolling way without carrying rubber, and rubber preparation is more stable and reliable. A cutter of the rubber cutting mechanism can be adjusted in a small length range under the action of a horizontal / vertical guide pair of the cutter for completing rubber cutting, so that influence on the width of the rubber sticking wheel is eliminated, and the trouble of the need of different rubber cutting belt lengths in different processes is eliminated.

Description

technical field [0001] The invention relates to a lithium-ion battery production equipment, in particular to a vertical gluing device for a fully automatic winding machine. Background technique [0002] Winding is an essential process in the production process of lithium-ion batteries, and it is also a key process that directly affects various performances such as battery safety, capacity, and consistency. [0003] The so-called winding is to continuously assemble the prepared positive and negative electrode sheets and separator materials on a winding needle of a certain specification to complete the process of forming the main body of the battery, and roll the positive and negative electrode sheets and separator film The winding accuracy is controlled within the tolerance range required by the process. The gluing device is one of the main components of the automatic winding machine, and it is a device for pasting and covering the ending part of the battery core. [0004] ...

AI Technical Summary

Problems solved by technology

There are disadvantages in the above structures. For the method of sticking the adhesive tape with the adhesive block, the sticking position of the tape is relatively unique, and the position of the sticking glue cannot be changed according to the position of the end; while the glue sticking method of the rubber roller has the advantage of being easy to change the sticking position , but this way of glue preparation is easy to cause the tape to fall off during the handling process or the tape adsorption position deviates, resulting in tape position shift or tape folding or material roll loosening
