The gluing assembly 452 includes a connecting gluing driving member 4521 and a gluing portion 4522.

When the glue-taking wheel 4542 is located at the glue-taking position, the axial direction of the glue-taking wheel 4542 is parallel to the glue feeding direction, and the glue-taking wheel 4542 can absorb the cut tape. When the glue wheel 4542 is located at the glue sticking position, the glue wheel 4542 corresponds to the glue sticking station, and the axis of the glue wheel 4542 is parallel to the axis of the cell, and the glue wheel 4542 can remove the tape along the axis of the cell. Paste it on the cell of the glue station.

In the above glue sticking device, after the glue feeding driver 4511 drives the glue clamping part 4512 to pull out the adhesive tape along the glue feeding direction, the glue pressing driver 4521 drives the glue pressing part 4522 to press the adhesive tape onto the glue taking wheel 4542 . Then, the glue cutting driver 4531 drives the glue cutting knife 4532 to cut the adhesive tape, and the cut adhesive tape is adsorbed on the glue taking wheel 4542 . Since the axial direction of the glue taking wheel 4542 is parallel to the glue feeding direction and the axial direction of the cell, when the cut tape is adsorbed on the glue taking wheel 4542, the length direction of the tape is parallel to the axial direction of the glue taking wheel 4542, so that the When the tape can be attached to the cell along the axial direction of the cell, the amount of tape can be saved. Moreover, the way of sticking the tape on the battery core along the axial direction of the battery core will not affect the tightness of the winding of the battery core, which can prevent the battery core from becoming tight after being glued and pulling the core during unloading, thereby improving the use of the above-mentioned stickers. The production quality of the winding equipment of the glue mechanism 45. In addition, since the tape is cut and then attached to the cell, the length and flatness of each tape remain consistent, thereby ensuring the consistency of cell production.

Specifically, referring mainly to FIG. 8 , the gluing driver 4521 includes a first gluing driver 45211 and a second gluing driver 45212 .

That is, there is no relative displacement between the glue cutting mechanism and the glue feeding assembly 451 in the glue feeding direction. It can be understood that, in other embodiments, the glue cutting driver 4531 can also be directly connected to the rack 10 . At this time, in order to prevent the glue cutting mechanism from touching the glue cutting mechanism when the glue clamping portion 4512 moves along the glue feeding direction, the glue cutting mechanism needs to be arranged on the side of the glue clamping portion 4512 away from the glue taking wheel 4542 . At this time, the distance between the glue cutting mechanism and the tape becomes larger, and the glue cutter 4532 needs to move a larger distance when cutting the tape, which is not conducive to improving the working efficiency of the glue sticking device.

Referring mainly to FIG. 8 , the glue feeding assembly 451 further includes an auxiliary driving member 4513 , the auxiliary driving member 4513 is connected with the glue feeding driving member 4511 , and the glue clamping portion 4512 is connected with the auxiliary driving member 4513 .

The glue removal driver 4541 includes a first glue removal driver 45411 and a second glue removal driver 45412. The first glue removal driver 45411 is connected to the frame 10, the second glue removal driver 45412 is connected to the mounting member 4543, and the first glue removal driver 45412 is connected to the mounting member 4543. Both the glue-taking driving member 45411 and the second glue-taking driving member 45412 can drive the mounting member 4543 to rotate, so that the glue-taking wheel 4542 swings between the glue-taking position and the glue-applying position.

Specifically, the first glue-taking driving member 45411 and the second glue-taking driving member 45412 are both air cylinders, and the stroke and thrust of the first glue-taking driving member 45411 are larger than those of the second glue-taking driving member 45412 .

The synergistic effect of the two can make the glue wheel 4542 move quickly and accurately.

It should be noted that, in this embodiment, the glue-taking driving member 4541 drives the glue-taking wheel 4542 to swing relative to the frame 10, so that the glue-taking wheel 4542 reciprocates between the glue-taking position and the glue-applying position. Of course, in other embodiments, the glue-taking driver 4541 can also drive the glue-taking wheel 4542 to slide relative to the frame 10 .

Further, referring mainly to FIG. 7 , the outer peripheral surface of the glue wheel 4542 has an arcuate portion 45421 and a flat portion 45422 , and the flat portion 45422 is provided with a vacuum hole 45423 . In this way, the tape can be adsorbed on the flat portion 45422, making the tape more flat.

It can be understood that, in this embodiment, the glue sticking mechanism 45 further includes a vacuum generator (not shown in the figure) and a controller (not shown in the figure), and the vacuum generator is connected with the glue taking wheel 4542 to make the vacuum The hole 45423 can be switched between a vacuum state and a non-vacuum state.

In this way, when the glue-taking wheel 4542 moves to the glue-taking position, the self-rotation driving member 4544 can drive the glue-taking wheel 4542 to rotate to the position where its vacuum hole 45423 faces the tape, so as to suck the tape. When the glue-taking driving member 4541 drives the glue-taking wheel 4542 to move to the glue sticking position, the self-rotation driving member 4544 can also drive the glue-taking wheel 4542 to rotate, so that the tape on the glue-taking wheel 4542 is facing the battery core, so that the tape is attached to the on the battery. Moreover, when the glue roller 4542 rotates, it can also smooth the tape, so that the tape attached to the battery core is more flat and firm.

It should be noted that in other embodiments, the rotational drive 4544 may also be eliminated.
