When the needle winding assembly 411 rotates to the winding station, the needle discharging assembly 413 drives the needle sheath 4111 to move axially along the rotary table 4123 relative to the rotary table 4123 to drive the first winding needle 4113, the second winding needle 4115 and the material clamping needle 4116 to extend, so that the septum is located between the material clamping needle 4116 and the second winding needle 4115.

After the diaphragm between the winding station and the rubberizing station is cut off, the winding needle assembly 411 of the winding station starts to wind the next battery cell again, and the winding needle assembly 411 of the rubberizing station continues to rotate so as to wind the cut-off tailings.
Further, the diaphragm severing mechanism 44 also includes an adjustment assembly 443, with the adjustment assembly 443 including an adjustment drive 4431 and an adjustment wheel 4432. The adjusting driving piece 4431 is connected with the material pressing driving piece 4421 and can drive the adjusting wheel 4432 to be close to the battery cell of the rubberizing station so as to limit the unwounded diaphragm and pole piece on the rubberizing station from falling.
Referring mainly to fig. 7 to 9, the winding device 40 further includes a glue applying mechanism 45, and the glue applying mechanism 45 includes a glue feeding assembly 451, a glue pressing assembly 452, a glue cutting assembly 453, and a glue taking assembly 454. The glue feeding assembly 451 comprises a glue feeding driving element 4511 and a glue clamping portion 4512 which are connected, wherein the glue feeding driving element 4511 is connected with the frame 10 and can drive the glue clamping portion 4512 to reciprocate along the glue feeding direction so as to pull out the adhesive tape on the glue disc 4546. The glue pressing component 452 comprises a glue pressing driving part 4521 and a glue pressing part 4522 which are connected, the glue pressing driving part 4521 is connected with the rack 10, and the glue pressing part 4522 can be driven to press the adhesive tape. The glue cutting assembly 453 comprises a glue cutting driving member 4531 and a glue cutting knife 4532 which are connected, wherein the glue cutting driving member 4531 is connected with the rack 10 and can drive the glue cutting knife 4532 to move so as to cut off the adhesive tape. The glue taking assembly 454 comprises a glue taking driving part 4541 and a glue taking wheel 4542 which are connected, wherein the glue taking driving part 4541 is connected with the rack 10 and can drive the glue taking wheel 4542 to reciprocate between a glue taking position and a glue applying position.
When the rubber taking wheel 4542 is located at the rubber taking position, the axial direction of the rubber taking wheel 4542 is parallel to the rubber feeding direction, and the rubber taking wheel 4542 can suck the cut rubber belt. When the rubber taking wheel 4542 is located at the rubberizing position, the rubber taking wheel 4542 corresponds to the rubberizing station, the axial direction of the rubber taking wheel 4542 is parallel to the axial direction of the battery cell, and the rubber taking wheel 4542 can paste the adhesive tape onto the battery cell at the rubberizing station along the axial direction of the battery cell.
In the above tape pasting apparatus, the tape feeding driving element 4511 drives the tape clamping portion 4512 to pull out the tape along the tape feeding direction, and the tape pressing driving element 4521 drives the tape pressing portion 4522 to press the tape onto the tape taking wheel 4542. Then, the tape cutting driving member 4531 drives the tape cutting knife 4532 to cut the tape, and the cut tape is adsorbed to the tape taking wheel 4542. Because the axial direction of the rubber taking wheel 4542 is parallel to the rubber feeding direction and the axial direction of the battery cell, when the cut adhesive tape is adsorbed on the rubber taking wheel 4542, the length direction of the adhesive tape is parallel to the axial direction of the rubber taking wheel 4542, so that the adhesive tape can be pasted on the battery cell along the axial direction of the battery cell, and the using amount of the adhesive tape is saved. Moreover, the mode of pasting the adhesive tape on the battery core along the axial direction of the battery core does not influence the tightness degree of the winding of the battery core, and the phenomenon that the battery core becomes tight after being pasted with the adhesive tape and loosens the core during discharging can be avoided, so that the production quality of the winding equipment adopting the adhesive tape pasting mechanism 45 is improved. In addition, because the adhesive tape is cut off and then attached to the battery cell, the length and the flatness of each adhesive tape are kept consistent, and the production consistency of the battery cell can be ensured.
Specifically, referring primarily to fig. 8, the glue driver 4521 includes a first glue driver 45211 and a second glue driver 45212. The first caulking driving piece 45211 is connected with the frame 10, and the second caulking driving piece 45212 is connected with the caulking part 4522. The first glue pressing driving member 45211 can drive the glue pressing part 4522 to move along the glue feeding direction through the second glue pressing driving member 45212, and the second glue pressing driving member 45212 can drive the glue pressing part 4522 to press the adhesive tape to the glue taking wheel 4542.
Before the second glue pressing driving member 45212 drives the glue pressing part 4522 to press the adhesive tape onto the glue taking wheel 4542, the first glue pressing driving member 45211 drives the glue pressing part 4522 to approach the glue clamping part 4512 in the glue feeding direction through the second glue pressing driving member 45212. After the second glue pressing driving member 45212 drives the glue pressing part 4522 to press the adhesive tape onto the glue taking wheel 4542, the first glue pressing driving member 45211 drives the glue pressing part 4522 to reset through the second glue pressing driving member 45212. In the process of resetting of the rubber pressing portion 4522, the rubber pressing portion 4522 can smooth the adhesive tape on the rubber taking wheel 4542, so that the adhesive tape is smoother. Finally, the second glue pressing driving member 45212 drives the glue pressing portion 4522 to reset.
Further, the glue cutting driving member 4531 is connected to the glue feeding driving member 4511, and the glue feeding driving member 4511 can drive the glue clamping portion 4512 and the glue cutting assembly 453 to reciprocate in the glue feeding direction together. That is, the glue cutting assembly and the glue feeding assembly 451 do not have relative displacement in the glue feeding direction. It is understood that in other embodiments, the glue cutting drive 4531 may be directly connected to the frame 10. At this time, in order to avoid that the glue clamping portion 4512 does not touch the glue cutting assembly when moving in the glue feeding direction, the glue cutting assembly needs to be arranged on the side of the glue clamping portion 4512 away from the glue taking wheel 4542. At this moment, the distance between the rubber cutting assembly and the rubber belt becomes large, and the rubber cutting knife 4532 needs to move a larger distance when cutting off the rubber belt, which is not beneficial to improving the working efficiency of the rubber coating device.
Referring primarily to fig. 8, the glue feeding assembly 451 further includes an auxiliary drive 4513, the auxiliary drive 4513 is connected to the glue feeding drive 4511, and the glue clamping portion 4512 is connected to the auxiliary drive 4513. Send gluey driving piece 4511 can pass through auxiliary driving piece 4513 drive doubling portion 4512 and move along sending gluey direction, and auxiliary driving piece 4513 can drive doubling portion 4512 and move along being close to the direction of getting gluey wheel 4542 to make the sticky tape be close to and get gluey wheel 4542, make things convenient for glue pressing portion 4522 to compress tightly the sticky tape to getting gluey wheel 4542 on.
