Adhesive mounting mechanism, full-automatic pole piece manufacturing machine and battery core winding equipment

Abstract

The invention discloses an adhesive mounting mechanism, which comprises a first adhesive mounting mechanism for mounting an adhesive from one side of a pole piece, wherein the first adhesive mounting mechanism comprises a first adhesive clamping component, a first adhesive pulling component, a first adhesive connecting component, a first adhesive cutting component and a first adhesive pressing block; the first adhesive clamping component and the first adhesive connecting component are arranged at two sides of the first adhesive pressing block; the first adhesive connecting component comprises a first adhesive rolling wheel and a first adhesive taking mechanism; the first adhesive pulling component is used for pulling out an adhesive tape clamped by the first adhesive clamping component and conveying the adhesive tape next to the first adhesive pressing block; the first adhesive connecting component crosses the first adhesive pressing block from the other side and connects the adhesive tape conveyed from the first adhesive clamping component in a supporting manner through the first adhesive rolling wheel; the first adhesive cutting component cuts off the adhesive tape with a set length; and then the first adhesive taking mechanism assists the cut adhesive tape in being accurately absorbed on the first adhesive pressing block. According to the adhesive mounting mechanism disclosed by the invention, high-precision adhesive mounting can be achieved.

Description

technical field [0001] The invention relates to the technical field of battery manufacturing equipment, in particular to a gluing mechanism with high gluing precision and high production efficiency, a fully automatic pole piece making machine and battery winding equipment. Background technique [0002] Lithium battery is a device that stores charge and is widely used in various electrical equipment. [0003] The pole ear is a raw material of lithium-ion polymer battery products. It is a metal conductor that leads the positive and negative poles out of the battery cell. It is the ear of the positive and negative poles of the battery and the contact point during charging and discharging. This contact is a connection inside the battery. The tabs are divided into three materials. The positive electrode of the battery uses aluminum (Al) material (the outermost end of the aluminum material needs to be welded with a part of nickel strip), the negative electrode uses nickel (Ni) ma...

AI Technical Summary

Problems solved by technology

However, in order to ensure the working space of the pressing block, the existing glue feeding mechanism usually cuts the tape at a far position by the glue feeding mechanism, and cannot send the tape forward to the processing position of the pressing block. Generally, it is stretched by a separate mechanical clamp Go out and pinch the cut tape and pull the tape

At the same time, when the mechanical clamp stretches out to clamp the belt, it must keep a certain gap with the working rubber block to avoid damaging the working parts. Therefore, in order to ensure sufficient working space for each other, the existing rubber block is usually made into a 7-shaped shape. As a result, the process of taking glue cannot be accurately controlled. Moreover, when the mechanical gripper picks up the tape, the adhesive tape is often unstable, or the tape cannot be pulled to feed because of insufficient adhesion.

[0006] In addition, the traditional rubber block is usually designed as a small size rubber block in order to make small-sized batteries. At the same time, in order to absorb the tape, the processing surface of the rubber block will be designed with multiple suction holes to absorb the tape. If the rubber block mechanism is too designed There will be a small problem of not being able to absorb the tape

Moreover, the pressure of the small-sized pressing block is not enough when applying the glue, the glue is not stable, and the effect of the glue is poor.
