Example Embodiment

[0027] Example

[0028] In order to solve the problem of blanking after the round needle is wound and to solve the problem of wrinkling and sagging of the inner ring of the elliptical needle, please refer to Figures 1~4 , this embodiment provides a circular rolling needle blanking clamp press block auxiliary blanking mechanism for circular rolling needle auxiliary blanking, which includes a clamping jaw drive device 1, an upper clamping jaw 2 and a lower clamping jaw 3. The clamping jaws One side of the driving device 1 is provided with a vertical guide rail, and the upper jaw 2 and the lower jaw 3 are arranged to move up and down on the vertical guide rail, and are driven to move up and down by the jaw driving device 1. The clamping device is driven by the clamping jaw driving device 1 and the lower clamping jaw 3 to clamp both sides of the battery cell 20, so that the round needle 10 can be pulled out from the battery core 20.

[0029] In this embodiment, the clamping jaw ...

Abstract

The invention discloses a round winding needle blanking clamping and pressing block auxiliary blanking mechanism which is used for round winding needle auxiliary blanking and comprises a clamping jaw driving device, an upper clamping jaw and a lower clamping jaw, a vertical guide rail is arranged on one side of the clamping jaw driving device, and the upper clamping jaw and the lower clamping jaw are arranged on the vertical guide rail in an up-down moving mode and driven by the clamping jaw driving device to move up and down. A clamping and pressing device facing the lower clamping jaw is arranged in the upper clamping jaw, and the clamping and pressing device and the lower clamping jaw are driven by the clamping jaw driving device to clamp the two sides of the battery cell, so that the round winding needle is conveniently pulled out from the interior of the battery cell. In order to solve the problems of blanking after winding of a round winding needle and wrinkling and edge collapse of an inner ring diaphragm of an elliptical winding needle, the invention provides the auxiliary blanking mechanism for the blanking clamping and pressing block of the round winding needle, which is used for auxiliary blanking of the round winding needle, can meet mode efficient blanking of a round winding needle structure, and is compact in structure, stable in operation and high in efficiency. And the situation that the subsequent treatment of the battery cell is affected due to unbalanced stress of the battery cell after needle extraction or rolling of the battery cell in the moving process can be avoided.

Description

technical field [0001] The invention relates to the field of battery cell winding, in particular to an auxiliary blanking mechanism of a round needle blanking clamp and pressing block. Background technique [0002] With the continuous development of the economy and the continuous progress of the society, various material consumer goods are provided for people's production and life, and electronic products are one of the various material consumer goods. [0003] Among them, electronic products, such as mobile phones, computers, tablets, digital cameras and smart watches, are inseparable from the use of lithium batteries, thus creating a good development platform for the development of the lithium battery industry. [0004] At present, the winding machine in the lithium battery industry usually uses an elliptical winding needle when winding the battery cell, because the elliptical winding needle is convenient for pre-compression forming. However, during the winding process of...
