[0002] With the wide use of new energy batteries, the demand for battery electrodes is also increasing continuously. Among them, for the convenience of placement, people usually wind the electrodes on a paper tube. However, due to the use of manual labor in the traditional winding process, the production efficiency is low. Therefore, some manufacturers have made further research and development.

[0003] For example, Chinese Patent Document CN205099042U discloses a pole piece winding device, which includes a rotating shaft mechanism and a rotating power mechanism.

[0004] However, the above-mentioned pole piece winding device has the following problems:

[0005] Although the above-mentioned pole piece winding device can fix the paper tube sleeved on the sleeve through the expansion block, so that the rotating power mechanism drives the paper tube to rotate at a high speed synchronously to wind the pole piece, but due to the fast winding speed of the pole piece on the paper tube, it is also necessary to frequently disassemble and replace the paper tube. And after the end of the paper tube is fixed by the above-mentioned pole piece winding device, it is very difficult for the operator to disassemble and assemble the paper tube from the outside, which ultimately slows down the production efficiency.

[0033] To better understand the technical solutions and beneficial effects of the present disclosure, the present disclosure will be further described in detail below with specific embodiments:

[0034] AsFigure 1 As shown, the reel snap mechanism 100 of an embodiment includes a guiding slide rail 110, a plugging slide arm 120, and a telescopic stopper 130. The guiding slide rail 110 and the telescopic stopper 130 are respectively used for fixedly installing on one side of the frame. The plugging slide arm 120 is arranged on the guiding slide rail 110. Reel hanging buckle grooves 1210 and first positioning bayonets 1220 are respectively formed at two ends of the plugging slide arm 120. The reel hanging buckle grooves 1210 are used for being oppositely arranged with respect to the reel embedding positions on the other side of the frame to jointly support the pole reel. The telescopic stopper 130 is arranged on one side of the plugging slide arm 120. The clamping part of the telescopic stopper 130 is telescopically inserted and pulled out of the first positioning bayonet 1220. The plugging slide arm 120 is slidably connected to the guiding slide rail 110 so that the reel hanging buckle grooves 1210 approach to lift or slide away from the pole reel.

[0035] It can be understood that compared with the pole piece winding device of the prior art, in the above-mentioned reel snap mechanism 100, since the plugging slide arm 120 is slidably connected to the guiding slide rail 110, the plugging slide arm 120 can be pushed to move, so that the position of the reel hanging buckle grooves 1210 of the plugging slide arm 120 can be opposite to the position of the reel embedding positions on the other side of the frame. By inserting the clamping part of the telescopic stopper 130 into the first positioning bayonet 1220 of the plugging slide arm 120, the position of the plugging slide arm 120 is fixed. When the pole piece needs to be wound, the other end of the pole reel can be embedded in the reel hanging buckle grooves 1210, and one end of the pole reel is arranged at the reel embedding position to realize the stable installation of the pole reel. When the pole reel needs to be disassembled and replaced, the clamping part of the telescopic stopper 130 can be pulled out of the first positioning bayonet 1220 of the plugging slide arm 120, and the plugging slide arm 120 is pushed to slide, so that the reel hanging buckle grooves 1210 of the plugging slide arm 120 are separated from one end of the pole reel. In this way, the operator can conveniently pull one end of the pole reel from the outside, so that the other end of the pole reel can be quickly pulled out of the reel embedding position, and finally the disassembly and assembly speed of the pole reel can be accelerated and the production efficiency can be improved.

[0036] Combined with Figure 1As shown, in one embodiment, the telescopic stopper 130 includes a push-pull drive 1310 and a limit post 1320; the push-pull drive 1310 is used for fixed installation on the frame and is located on one side of the insertion and extraction sliding arm 120; the limit post 1320 is arranged on the push rod of the push-pull drive 1310, and the limit post 1320 is inserted into or disengaged from the first positioning bayonet 1220 under drive. It can be understood that by fixedly installing the push-pull drive 1310 on the frame, since the push-pull drive 1310 is located on one side of the insertion and extraction sliding arm 120 and the limit post 1320 is arranged on the push rod of the push-pull drive 1310, when the reel hanging buckle groove 1210 lifts the extremely large reel, the push-pull drive 1310 can be used to push the limit post 1320 to be quickly inserted into the first positioning bayonet 1220; and when the reel hanging buckle groove 1210 disengages from the extremely large reel, the push-pull drive 1310 can be used to pull the limit post 1320 to be quickly pulled out from the first positioning bayonet 1220, so as to realize the quick locking and unlocking of the telescopic stopper 130 to the insertion and extraction sliding arm 120, and further improve the disassembly and assembly speed of the extremely large reel.

[0037] Combined with Figure 2 As shown, in this embodiment, the limit post 1320 includes a support 1321 and a caster 1322; the support 1321 is fixed on the push rod of the push-pull drive 1310, the support 1321 protrudes a triangular piece 132a towards the insertion and extraction sliding arm 120, and the caster 1322 is rotatably arranged on the triangular piece 132a; the caster 1322 cooperates with the first positioning bayonet 1220. It can be understood that since the support 1321 is fixed on the push rod of the push-pull drive 1310 and the caster 1322 is rotatably arranged on the triangular piece 132a of the support 1321, the caster 1322 can be stably installed under the support of the triangular piece 132a. At the same time, the caster 1322 can also enter or disengage from the first positioning bayonet 1220 under the drive of the push-pull drive 1310. At this time, the caster 1322 can roll on the inner wall of the first positioning bayonet 1220, so that the process of the caster 1322 entering and exiting the first positioning bayonet 1220 is smoother and more convenient to use.

[0038] Combined with Figure 3 And Figure 4As shown, in one embodiment, a tongue 1230 is telescopically arranged on the insertion and extraction sliding arm 120; the tongue 1230 is located at the notch position of the reel hanging buckle groove 1210 and forms a blocking space 123a with the inner wall of the reel hanging buckle groove 1210, and the blocking space 123a is used to accommodate the extremely large reel. It can be understood that by arranging the tongue 1230 at the notch position of the reel hanging buckle groove 1210, the tongue 1230 can form the blocking space 123a with the inner wall of the reel hanging buckle groove 1210, and the extremely large reel can be constrained inside the reel hanging buckle groove 1210 through the blocking space 123a, so as to prevent the extremely large reel from coming out during the process of winding the pole piece. At the same time, since the tongue 1230 is telescopically arranged on the insertion and extraction sliding arm 120, when it is necessary to disassemble and replace the extremely large reel, the tongue 1230 can be contracted into the hole of the insertion and extraction sliding arm 120. In this way, due to the lack of the constraint of the tongue 1230, the extremely large reel can also be normally removed from the notch position of the reel hanging buckle groove 1210.

[0039] Combined with Figure 4 As shown, in this embodiment, a telescopic driver 1240 is also fixedly arranged on the insertion and extraction sliding arm 120, and the telescopic rod of the telescopic driver 1240 is connected to the tongue 1230. It can be understood that since the tongue 1230 is connected to the telescopic rod of the telescopic driver 1240, the tongue 1230 can be quickly pushed and pulled to expand and contract through the telescopic driver 1240, thereby reducing the amount of manual operation and being more convenient to use. Specifically, a guide sliding hole is formed on the insertion and extraction sliding arm 120, and the tongue 1230 is slidably arranged in the guide sliding hole. Under the guiding action of the guide sliding hole, the telescopic driver 1240 can drive the tongue 1230 to contract and slide more smoothly.

[0040] Combined with Figure 3 And Figure 4 As shown, in one embodiment, the end of the tongue 1230 is inclined from the inner side of the reel hanging buckle groove 1210 to the outer side of the reel hanging buckle groove 1210 to form a slipping surface 1231. Specifically, the slipping surface 1231 is arranged opposite to the opening of the reel hanging buckle groove 1210, and in the direction away from the telescopic driver 1240, the distance between the slipping surface 1231 and the insertion and extraction sliding arm 120 gradually increases. It can be understood that since the slipping surface 1231 at the end of the tongue 1230 is inclined from the inner side of the reel hanging buckle groove 1210 to the outer side of the reel hanging buckle groove 1210, when the reel hanging buckle groove is pulled away from the extremely large reel, the extremely large reel can slide along the slipping surface 1231 and thus press on the end of the tongue 1230, causing the tongue 1230 to contract. In this way, the extremely large reel can also be normally removed from the notch position of the reel hanging buckle groove 1210.

[0041] Combined with Figure 1As shown, in one embodiment, a push-pull handle 1250 is provided on the insertion and extraction sliding arm 120. It can be understood that by providing the push-pull handle 1250 on the insertion and extraction sliding arm 120, the operator can quickly push the insertion and extraction sliding arm 120 close to lift or slide away from the pole roll paper tube through the push-pull handle 1250, thereby further improving the replacement efficiency of the pole roll paper tube and making it more convenient to use.

[0042] Combined with Figure 3 As shown, in one embodiment, a second positioning bayonet 1260 is further provided on the insertion and extraction sliding arm 120 near the reel hanging buckle groove 1210. The second positioning bayonet 1260 is used to cooperate with the clamping portion of the telescopic limiter 130 when the reel hanging buckle groove 1210 slides away from the pole roll paper tube. It can be understood that since the insertion and extraction sliding arm 120 on the insertion and extraction sliding arm 120 is arranged close to the reel hanging buckle groove 1210, when the reel hanging buckle groove 1210 disengages from the pole roll paper tube, it can push the insertion and extraction sliding arm 120 to slide towards the position close to the telescopic limiter 130, so that the second positioning bayonet 1260 cooperates with the clamping portion of the telescopic limiter 130. After the clamping portion of the telescopic limiter 130 cooperates with the second positioning bayonet 1260, it can position the insertion and extraction sliding arm 120 and prevent the insertion and extraction sliding arm 120 from shaking during the replacement of the pole roll paper tube and affecting the disassembly and assembly of the pole roll paper tube.

[0043] Combined with Figure 2 As shown, in one embodiment, a guiding sliding slope 1221 is provided at the entrance position of the first positioning bayonet 1220 on the insertion and extraction sliding arm 120. The guiding sliding slope 1221 inclines from the outside of the first positioning bayonet 1220 to the inside of the first positioning bayonet 1220. It can be understood that since the guiding sliding slope 1221 inclines from the outside of the first positioning bayonet 1220 to the inside of the first positioning bayonet 1220, when it is necessary to wind the pole piece through the pole roll paper tube, the clamping portion of the telescopic limiter 130 can slide along the guiding sliding slope 1221 towards the inside of the first positioning bayonet 1220, so as to be assembled with the first positioning bayonet 1220 more quickly, and then the insertion and extraction sliding arm 120 can be quickly positioned at the position opposite to the reel embedding position, making it more convenient to use.

[0044] Combined with Figure 4As shown, in one of the embodiments, the insertion and extraction sliding arm 120 is provided with a guiding inclined surface 1261 at the entrance position of the second positioning bayonet 1260. The guiding inclined surface 1261 inclines from the outside of the second positioning bayonet 1260 towards the inside of the second positioning bayonet 1260. It can be understood that since the guiding inclined surface 1261 inclines from the outside of the second positioning bayonet 1260 towards the inside of the second positioning bayonet 1260, when it is necessary to replace the pole roll paper tube, the clamping part of the telescopic stopper 130 can slide along the guiding inclined surface 1261 towards the inside of the second positioning bayonet 1260, so as to be assembled with the second positioning bayonet 1260 more quickly, and then the insertion and extraction sliding arm 120 can be quickly positioned at a position separated from the pole roll paper tube, making the use more convenient.

[0045] Combined with Figure 1 And Figure 5 As shown, the present disclosure also provides a pole piece winding device 10, which includes a frame 200 and the reel sliding buckle mechanism 100 of any one of the above embodiments; a guiding slide rail 110 and a telescopic stopper 130 are respectively fixedly installed on one side of the frame 200, and a reel embedding position 210 is provided on the other side of the frame 200; the reel hanging buckle groove 1210 is arranged opposite to the reel embedding position 210 on the other side of the frame 200 to jointly support the pole roll paper tube. It can be understood that by applying the reel sliding buckle mechanism 100 of the present disclosure to the pole piece winding device 10, since the insertion and extraction sliding arm 120 is slidably connected to the guiding slide rail 110, the insertion and extraction sliding arm 120 can be pushed to move, so that the position of the reel hanging buckle groove 1210 of the insertion and extraction sliding arm 120 can be opposite to the position of the reel embedding position 210 on the other side of the frame 200, and by inserting the clamping part of the telescopic stopper 130 into the first positioning bayonet 1220 of the insertion and extraction sliding arm 120, the position of the insertion and extraction sliding arm 120 is fixed. When it is necessary to wind the pole piece, the other end of the pole roll paper tube can be embedded in the reel hanging buckle groove 1210, and one end of the pole roll paper tube is arranged at the reel embedding position 210 to realize the stable installation of the pole roll paper tube. When it is necessary to disassemble and replace the pole roll paper tube, the clamping part of the telescopic stopper 130 can be pulled out from the first positioning bayonet 1220 of the insertion and extraction sliding arm 120, and the insertion and extraction sliding arm 120 can be pushed to slide, so that the reel hanging buckle groove 1210 of the insertion and extraction sliding arm 120 is separated from one end of the pole roll paper tube. In this way, the operator can conveniently pull one end of the pole roll paper tube from the outside, so that the other end of the pole roll paper tube can be quickly pulled out from the reel embedding position 210, and finally the disassembly and assembly speed of the pole roll paper tube can be accelerated and the production efficiency can be improved.

[0046] Compared with the prior art, the present disclosure has at least the following advantages:

[0047] The above-mentioned drum slip-locking mechanism 100 can push the insertion and extraction slide arm 120 to move because the insertion and extraction slide arm 120 is slidably connected to the guide rail 110, so that the position of the drum hanging slot 1210 of the insertion and extraction slide arm 120 can be opposite to the position of the drum installation position on the other side of the frame. By inserting the clamping part of the telescopic stopper 130 into the first positioning bayonet 1220 of the insertion and extraction slide arm 120, the position of the insertion and extraction slide arm 120 is fixed. When the pole piece needs to be wound, the other end of the pole winding paper tube can be inserted into the drum hanging slot 1210, and one end of the pole winding paper tube can be arranged at the drum installation position to realize the stable installation of the pole winding paper tube. When the pole winding paper tube needs to be disassembled and replaced, the clamping part of the telescopic stopper 130 can be pulled out from the first positioning bayonet 1220 of the insertion and extraction slide arm 120, and the insertion and extraction slide arm 120 can be pushed to slide, so that the drum hanging slot 1210 of the insertion and extraction slide arm 120 is separated from one end of the pole winding paper tube. In this way, the operator can easily pull one end of the pole winding paper tube from the outside, so that the other end of the pole winding paper tube can be quickly pulled out from the drum installation position, and finally the disassembly and assembly speed of the pole winding paper tube can be accelerated and the production efficiency can be improved.

[0048] The above embodiments only represent several implementation manners of the present disclosure, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present disclosure, several modifications and improvements can still be made, and these all belong to the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure patent shall be subject to the appended claims.
