Lithium battery winding and pasting mechanism

Abstract

The invention relates to a lithium battery winding and gluing mechanism, which is applied to lithium-ion battery cell production equipment. The winding and gluing mechanism includes a frame; The unwinding cylinder and the unwinding roller that control the unwinding of the tape reel on the tape roller are installed on the frame; multiple rollers for conveying the tape are installed on the frame; a glue preparation component is installed in the middle of the frame; The end of the frame is installed with a rubber pressing assembly that pulls the rubber preparation assembly over and crimps the tape to prevent the tape from turning and disjointing; the frame on the rear side of the rubber preparation assembly is provided with a glue cutting assembly that cuts the tape after the traction and crimping; The back side of the glue cutting component is pulled over and the frame on the upper side of the tape is also installed on the frame that absorbs the tape and turns the cut tape 90°; The final adhesive tape is sent to the gluing device of the gluing and pressing station of the battery cells to be glued.

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 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 l...

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
