Lithium battery winding and sticking mechanism

Abstract

The invention relates to a lithium battery winding and sticking mechanism which is applied to lithium ion battery cell manufacturing equipment. The winding and sticking mechanism comprises a machine frame; an adhesive tape roller capable of rotatablely releasing an adhesive tape is mounted at the initial end of the machine frame; an adhesive tap starting cylinder and an adhesive tap roller, which are used for controlling the unwinding of an adhesive tape spool on the adhesive tape roller, are mounted near the adhesive tap roller on the machine frame; a plurality of rollers for transporting adhesive tapes is mounted on the machine frame; an adhesive tap preparing component is mounted at the middle part of the machine frame; an adhesive tap holding component which is used for withholding the adhesive tape drew by the adhesive tap preparing component to prevent the adhesive tape from turning and being detached is mounted at the tail end of the machine frame; an adhesive tape cutting component for cutting the adhesive tape drew and withheld is mounted behind the adhesive tap preparing component on the machine frame; an absorbing and overturning component for turning over the cut adhesive tape is mounted above the adhesive tape drew from the rear part of the adhesive tape cutting component, on the machine frame; and a sticking device for delivering the cut adhesive tape to a battery cell to be sticked is mounted on one side of the absorbing and overturning component and on the machine frame.

Description

【Technical field】 [0001] The invention relates to manufacturing equipment of lithium ion battery cells, in particular to a lithium battery winding and sticking mechanism. 【Background technique】 [0002] Existing lithium battery cells are usually composed of overlapping positive and negative electrode sheets, separated from each other by a separator, and a termination tape is pasted on the end of the cell to realize bundling of the cell. Such as figure 1 with figure 2 As shown, a tape application device of a battery winding machine is disclosed. The delivery of the rubber application wheel device 1 on the device (through the application of the rubber wheel on it) cuts the direction of application of the adhesive tape and the conveyance of the adhesive tape on the tape roller 2. The direction is perpendicular to each other, and the conveyed tape is cut vertically, which makes the operation complicated during the cutting process, and it is inconvenient to adjust the cutting ...

AI Technical Summary

Problems solved by technology

like figure 1 and figure 2 As shown, a tape application device of a battery winding machine is disclosed. The delivery of the rubber application wheel device 1 on the device (through the application of the rubber wheel on it) cuts the direction of application of the adhesive tape and the conveyance of the adhesive tape on the tape roller 2. The direction is perpendicular to each other, and the conveyed tape is cut vertically, which makes the operation complicated during the cutting process, and it is inconvenient to adjust the cutting length of the tape, which is easy to cause plastic deformation of the tape, and the glue feeding position is not easy to adjust
