As shown in fig. 1 and 4, the rubberizing mechanism 500 in the present embodiment includes a tape splicing assembly 501 and a standby assembly 502. The tape receiving assembly 501 comprises a rubberizing element 525, wherein the rubberizing element 525 comprises a first adsorption element 527 and a second adsorption element 526, the first adsorption element 527 is used for adsorbing adhesive tape, and the second adsorption element 526 is used for adsorbing material tape; the backup assembly 502 is configured to place a length of tape onto the first absorbent component 527.

More specifically, the first absorbent element 527 attracts the tape, and the second absorbent element 526 attracts the tape (e.g., pole piece, membrane). The adhesive preparation assembly 502 may place a length of adhesive tape on the first suction attachment 527, and the adhesive preparation may be performed in the manner shown in fig. 1-3, or may be performed in any other suitable manner, for example, by pulling a length of adhesive tape with a pair of clamping jaws, placing it on the first suction attachment 527, and cutting it off. Because the adhesive preparation assembly can place a section of adhesive tape on the first absorption part 527, manual adhesive preparation is not needed in the tape splicing process, the adhesive tape adhesion part 525 has the functions of absorbing adhesive tapes and absorbing material tapes, the automation degree and the tape splicing efficiency are improved, and the space required in the tape splicing process is smaller.

As shown in fig. 1, 2 and 3, the present embodiment provides a specific structure of the rubberizing mechanism 500.

The glue preparation assembly 502 includes: a mounting plate 503, the mounting plate 503 is provided with a rotatable tape discharging member 504, a tape end holding member 505 and a first driving member 506. The tape discharging member 504 is used for loading a roll of tape, the tape end holding member 505 is used for holding an end of the tape, and the first driving member 506 is used for driving the first moving plate 507 to move in the first direction to approach or separate from the tape end holding member 505. The first moving plate 507 is provided with a second driving member 509, the second driving member 509 is connected with a second moving plate 510, the second moving plate 510 is provided with a rotatable rubber pulling roller 511, the rubber pulling roller 511 is used for winding adhesive tape, and the second driving member 509 is used for driving the rubber pulling roller 511 to move along a second direction to abut against or be away from the adhesive tape end part holding member 505; the first direction intersects the second direction.

More specifically, the tape dispenser 504 is mounted to the mounting plate 503 and is free to rotate or is driven to rotate by a drive mechanism to unwind the roll of tape and deliver the tape to the tape end holder 505. The tape end holder 505 may hold the tape end of the tape by suction or the like. For example, when the suction type structure is adopted, the tape end holder 505 can suck the tape end of the tape. The first driving member 506 is configured to drive the first moving plate 507 to move in a first direction to approach or separate from the adhesive tape end portion holding member 505, and the second driving member 509 is mounted on the first moving plate 507 and is capable of driving the second moving plate 510 to move in a second direction, for example, the second driving member 509 employs an air cylinder, a piston rod of the air cylinder is connected to the first moving plate 507, a cylinder body is connected to the second moving plate 510, or a piston rod of the air cylinder is connected to the second moving plate 510, and a cylinder body is connected to the first moving plate 507, so that the second moving plate 510 can move in the second direction by telescoping of the piston rod. The glue pulling roller 511 is mounted on the second moving plate 510, and can freely rotate or be driven to rotate by a driving member. The first direction intersects the second direction. Thus, the first driving member 506 can drive the pull roll 511 to move in a first direction to approach or move away from the tape end holder 505, and the second driving member 509 can drive the pull roll 511 to move in a second direction to abut or move away from the tape end holder 505.

When the preparation of the adhesive is required, the first driving member 506 drives the first moving plate 507 to move along the first direction so that the adhesive pulling roller 511 approaches the adhesive tape end holder 505, where "approach" means that the distance between the first moving plate 507 and the adhesive tape end holder 505 becomes smaller in the first direction. After the glue pulling roller 511 reaches above the tape end holder 505, the second driving member 509 drives the second moving plate 510 to move along the second direction so that the glue pulling roller 511 abuts against the tape end on the tape end holder 505 (which can be regarded as the glue pulling roller 511 abutting against the tape end holder 505 at this time), and therefore the glue pulling roller 511 abuts against the tape end. Then, the first driving member 506 continues to drive the first moving plate 507 to move along the first direction (the original moving direction is still kept moving at this time), the glue pulling roller 511 rotates, and the adhesive tape is adhered to the roller surface of the glue pulling roller 511, so that the glue pulling roller 511 winds a section of adhesive tape. Then, the tape end holder 505 no longer holds the tape end, and the second driving member 509 drives the second moving plate 510 away from the tape end holder 505 in the second direction, so that the pull roller 511 is also away from the tape end holder 505. Then, the first driving member 506 drives the first moving plate 507 in the first direction away from the tape end holding member 505, the tape discharging member 504 rotates, and the tape is pulled out by a certain length. After the first moving plate 507 reaches the predetermined position, the second driving member 509 drives the second moving plate 510 to approach the tape end holder 505 in the second direction, where "approaching" means that the distance between the pull roller 511 and the tape end holder 505 in the second direction becomes smaller. The tape end holder 505 and the first suction member 527 operate to hold a length of tape, and the tape pulling roller 511 unwinds the wound length of tape. After the first cutter 513 cuts the tape, a length of tape is placed on the first absorbent element 527. The tape splicing component 501 can utilize the second adsorption piece 526 to adsorb the material tape, and utilizes the first adsorption piece 527 to rubberize, so that automatic tape splicing preparation is realized, manual operation is not needed, the tape splicing efficiency is improved, and the structure is compact.

Finally, the second drive member 509 drives the second moving plate 510 away from the tape end holder 505 in the second direction, and enters the next standby cycle.

As shown in fig. 1, the mounting plate 503 is further mounted with a third driving member 512, and the third driving member 512 is used to drive the first cutter 513 to move to cut the adhesive tape. A first cutter 513 is located between the tape end holder 505 and the taping member 525.

More specifically, a gap can exist between the tape end holder 505 and the taping member 525, and the third driving member 512 drives the first cutter 513 to cut the tape between the tape end holder 505 and the taping member 525, so that a length of the tape can be placed on the first suction member 527, and a new tape end of the cut tape is held by the tape end holder 505. The whole structure layout is compact, and the space utilization rate is high. The third drive member 512 and the first cutter 513 can also be mounted in other suitable locations.

As shown in fig. 1 and 3, the second moving plate 510 is further provided with a fourth driving member 514, and the fourth driving member 514 is used for driving the pressing block 515 to clamp the glue pulling roll 511 or to unclamp the glue pulling roll 511.

More specifically, in the process of preparing the adhesive, after the adhesive tape is adhered to the roller surface of the adhesive pulling roller 511 and wound around the adhesive pulling roller 511, the fourth driving member 514 drives the pressing block 515 to clamp the adhesive pulling roller 511, so that the adhesive tape cannot fall off from the adhesive pulling roller 511 in the subsequent process of moving away from the adhesive tape end holding member 505 along the first direction. When the adhesive pulling roll 511 needs to place the adhesive tape on the first suction member 527 to flatten the wound adhesive tape, the fourth driving member 514 drives the pressing block 515 to loosen the adhesive pulling roll 511, and the adhesive pulling roll 511 can freely rotate, so that the adhesive tape stuck and wound on the roll surface of the adhesive pulling roll 511 can flatten, and the flatness when the adhesive tape is stuck to a material tape later is ensured.

As shown in fig. 1, the adhesive tape is conveyed from the adhesive tape discharging member 504 toward the adhesive tape end holding member 505, and a clamping block 516 is further provided between the adhesive tape discharging member 504 and the adhesive tape end holding member 505 on the conveying path of the adhesive tape, and the clamping block 516 is driven by a fifth driving member 517 to clamp or unclamp the adhesive tape.

More specifically, the fifth driver 517 may be a jaw cylinder and the clamp block 516 may be a pair of jaws of the jaw cylinder. Alternatively, the fifth driving member 517 may be another power source, and the clamping blocks 516 may be a pair of sliding blocks, which are driven by the fifth driving member 517 to move toward or away from each other. Before the first cutter 513 cuts off the adhesive tape, the fifth driving member can drive the clamping block 516 to clamp the adhesive tape, so that the adhesive tape can be ensured not to be pulled out of a new section by the first cutter 513 when being cut off, the adhesive tape is always kept flat, and the adhesive tape is prevented from being overlong when the adhesive tape is adhered subsequently.

As shown in fig. 1, on the conveying path of the adhesive tape, a tensioning roller 518 is further disposed between the adhesive tape discharging member 504 and the clamping block 516, the tensioning roller 518 is mounted on a third moving plate 519, the third moving plate 519 is slidably matched with the mounting plate 503, and a first elastic member 520 is disposed between the third moving plate 519 and the mounting plate 503 to provide a tensioning force.

More specifically, on the conveying path of the adhesive tape, the tensioning roller 518 needs to be bypassed, and the tensioning roller 518 is dependent on the tensioning force of the first elastic member 520 to always keep the adhesive tape in a tensioning state, so that the adhesive tape is smooth and can not be wrinkled, and the quality of the subsequent adhesive tape is improved.

As shown in fig. 1, on the conveying path of the adhesive tape, a first passing roller 521 and a second passing roller 522 are provided upstream and downstream of the tension roller 518, respectively. The two pass rollers serve to change the direction of tape transport, ensuring that the tape is as flat as possible between the tape end holder 505 and the pull roller 511.

As shown in fig. 1, this embodiment shows a suction type tape end holder 505. The tape end holder 505 is provided with a first suction hole 523, and the first suction hole 523 is used for sucking the tape, thereby holding the tape end on the tape end holder 505.

More specifically, the first suction hole 523 may be connected to a negative pressure mechanism, so that the adhesive tape is sucked on the adhesive tape end holder 505 by forming a negative pressure in the vicinity of the first suction hole 523.

As shown in fig. 5, the tape splicing assembly 501 of this embodiment includes a sixth driving element 524, where the sixth driving element 524 can drive the rubberizing element 525 to turn over, so that the first absorbing element 527 is in a glue state or in a tape splicing state.

More specifically, the sixth driving member 524 may be configured to drive the rubberizing member 525 to turn by hinging a piston rod of the cylinder to the rubberizing member 525, and may be configured to drive the rubberizing member 525 to turn by connecting an output shaft of the motor to the rubberizing member 525. In fig. 1 and 5, the first suction attachment member 527 is in a glue ready state in which the glue ready assembly 502 is capable of placing a length of tape onto the first suction attachment member 527, while the second suction attachment member 526 is capable of sucking on a working and/or a standby tape. After the sixth driving member 524 drives the rubberizing member 525 to turn over, the first absorbing member 527 is in a tape receiving state, in this state, the first absorbing member 527 faces the third direction, at this time, the second absorbing member 526 of the opposite other rubberizing mechanism 500 absorbs the tail end of the working tape and the head end of the standby tape, the first absorbing member 527 of one rubberizing mechanism 500 is close to the second absorbing member 526 of the other rubberizing mechanism 500, so that the adhesive tape is adhered to the tail end of the working tape and the head end of the standby tape, and the working tape and the standby tape are adhered together.

From the above description, the glue preparation, material absorption and adhesive material adhesion mechanisms in this embodiment do not need to be manually participated, and have high automation degree and high tape connection efficiency, and can realize glue preparation and glue adhesion by means of overturning the glue adhesion member 525, so that the occupied space is small.

As shown in fig. 1, in the gel-prepared state of the first suction member 527, the suction surface of the first suction member 527 is flush with the suction surface of the tape end holder 505 of the gel-prepared assembly 502. In this context, the level may mean that the suction surface of the first suction member 527 is in the same plane as the suction surface of the tape end holder 505, or that the suction surface of the first suction member 527 is slightly higher or lower than the suction surface of the tape end holder 505, for example, the suction surface of the first suction member 527 is 1mm, 3mm higher or 1mm, 3mm lower than the suction surface of the tape end holder 505, and the difference in height falls within the allowable error range, and may be regarded as the level of both suction surfaces. The two adsorption surfaces are flush, so that the adhesive tape can be ensured to be smoother, and the intercepting length is more accurate.

As shown in fig. 1, the first adsorption member 527 is provided with a second adsorption hole 528, the second adsorption hole 528 is used for adsorbing the adhesive tape, the second adsorption member 526 is provided with a third adsorption hole 508, and the third adsorption hole 508 is used for adsorbing the material tape. The second adsorption hole 528 and the third adsorption hole 508 have the same operation principle as the first adsorption hole 523, and thus will not be described in detail.

As shown in fig. 1, the second adsorbing element 526 includes a first adsorbing block 5261 and a second adsorbing block 5262 spaced apart from each other, the first adsorbing block 5261 is connected to a first vacuumizing device (not shown), the second adsorbing block 5262 is connected to a second vacuumizing device (not shown), and the first vacuumizing device and the second vacuumizing device can independently operate.

More specifically, the first adsorption mass 5261 and the second adsorption mass 5262 are provided with adsorption holes, the first adsorption mass 5261 is connected with a first vacuumizing device (not shown), the second adsorption mass is connected with a second vacuumizing device (not shown), and the first vacuumizing device and the second vacuumizing device can work independently, that is, the first vacuumizing device or the second vacuumizing device can work independently, and can work simultaneously, so that the first adsorption mass 5261 and the second adsorption mass 5262 can generate adsorption force respectively, or generate adsorption force simultaneously.

The whole process of preparing glue from the glue preparation component 502 to the tape connecting component 501 is as follows:

The tape end of the tape is sucked by the first suction hole 523 of the tape end holder 505, and the first suction member 527 of the tape applying member 525 is flush with the tape end holder 505 in a standby state. The first driving member 506 drives the first moving plate 507 to move in the first direction so that the adhesive pulling roller 511 approaches the adhesive tape end holder 505. After the glue roller 511 reaches above the tape end holder 505, the second driving member 509 drives the second moving plate 510 to move in the second direction so that the glue roller 511 abuts against the tape end on the tape end holder 505. Then, the first driving member 506 continues to drive the first moving plate 507 to move along the first direction, and the first moving plate is closer to the clamping block 516, the adhesive pulling roller 511 rotates, the adhesive tape is adhered to the roller surface of the adhesive pulling roller 511, and the adhesive pulling roller 511 winds a section of adhesive tape. The press block 515 then clamps the pull roll 511 against rotation. Then, the tape end holder 505 no longer attracts the tape end, and the second driving member 509 drives the second moving plate 510 away from the tape end holder in the second direction, so that the pull roller 511 is also away from the tape end holder 505. Then, the first driving member 506 drives the first moving plate 507 in the first direction away from the tape end holding member 505, the tape discharging member 504 rotates, and the tape is pulled out by a length. After the first moving plate 507 reaches the predetermined position, the second driving member 509 drives the second moving plate 510 to approach the tape end holder 505 in the second direction, and the first suction member 527 of the tape applying member 525 and the tape end holder 505 work to suck the tape. The fourth driving member 514 drives the pressing block 515 to release the glue pulling roller 511, the glue pulling roller 511 can rotate, and the adhesive tape stuck on the roller surface is flattened onto the first suction member 527. Then, the clamping block 516 clamps the tape, and the third driving member 512 drives the first cutter 513 to cut the tape between the tape end holder 505 and the taping member 525, so that a length of the tape can be placed on the first suction member 527 while a new tape end is sucked onto the tape end holder 505. Finally, the second drive member 509 drives the second moving plate 510 away from the tape end holder 505 in the second direction, and enters the next standby cycle.

As shown in fig. 4 and 5, the automatic reel changer 100 in the present embodiment includes: the rubberizing mechanism 500 as previously described. After the automatic coil replacing device 100 adopts the rubberizing mechanism 500 to paste the adhesive tape, the tape connecting efficiency can be improved, so that the coil replacing efficiency is improved, the production efficiency of the battery cell is improved, and the occupied factory space is small.

The automatic reel changer 100 further includes a first reel spool 101 and a second reel spool 102. Wherein the first unwind spool 101 and the second unwind spool 102 are used for loading reels. When one of the unwind shafts is used to load a work roll 201, the other unwind shaft is used to load a backup roll 202. Two rubberizing mechanisms 500 are oppositely disposed, one of which is labeled as a first rubberizing mechanism 529 and the other labeled as a second rubberizing mechanism 530 for clarity of description.

The tape receiving assembly 501 of the second rubberizing mechanism 530 is further provided with a second cutter 531, and the tape receiving assembly 501 of the first rubberizing mechanism 529 and the tape receiving assembly 501 of the second rubberizing mechanism 530 can be close to each other, so that the working tape absorbed by the second absorbing member 526 is cut by the second cutter 531, or the second cutter 531 can also cut the spare tape. The adhesive tape absorbed by the first absorbing member 527 of the second rubberizing mechanism 530 adheres the tail end of the work material tape and the head end of the spare material tape together in a state that the second absorbing member 526 of the first rubberizing mechanism 529 absorbs the tail end of the work material tape and the head end of the spare material tape.

More specifically, the first rubberizing mechanism 529 is disposed opposite to the second rubberizing mechanism 530, which means that when the rubberizing members 525 of the first rubberizing mechanism 529 are in a rubberized state, the rubberizing members 525 of the second rubberizing mechanism 530 are also in a rubberized state, the two second adsorbing members 526 are opposite in the third direction.

More specifically, after the backup assembly 502 places the tape on the first suction attachment 527 of the tape splicing assembly 501, the tape splicing assemblies 501 of the first and second rubberizing mechanisms 529 and 530 can be driven individually or together to approach or separate from each other, enabling the second cutter 531 to sever the tape and cause the tape to bond the tail end of the work tape and the leading end of the backup tape together, converting the backup roll 202 into a work roll for further unwinding.

As shown in fig. 1 to 6, the automatic reel changer 100 performs the following reel change process: the glue preparation assembly 502 of the first glue mechanism 529 places the tape on the first suction attachment 527 of the first glue mechanism 529, completing the glue preparation. The tape connecting assembly 501 of the first rubberizing mechanism 529 and the tape connecting assembly 501 of the second rubberizing mechanism 530 are close to each other, the rubberizing piece 525 of the first rubberizing mechanism 529 and the rubberizing piece 525 of the second rubberizing mechanism are mutually propped, under the effect of propping pressure, the rubberizing piece 525 of the second rubberizing mechanism 530 is retracted along the third direction to expose the second cutter 531, the working material tape unreeled by the first unreeled shaft 101 is cut off by the second cutter 531, and the tail end of the working material tape is adsorbed by the first adsorption block 5261 of the second rubberizing mechanism 530. Then, the tape connecting component 501 of the first rubberizing mechanism 529 and the tape connecting component 501 of the second rubberizing mechanism 530 are far away from each other, and the rubberizing piece 525 of the second rubberizing mechanism 530 is extended by the second elastic piece 532 to shield the second cutter 531. The first material taking member of the starting mechanism 300 tears the seal gum of the standby roll 202 and pulls the starting end of the standby tape to the transfer station, and the second material taking member of the tape transfer mechanism 400 transfers the starting end of the standby tape from the transfer station to the tape receiving station, specifically, between the first adsorption block 5261 of the first rubberizing mechanism 529 and the first adsorption block 5261 of the second rubberizing mechanism 530. The tape receiving assembly 501 of the first rubberizing mechanism 529 and the tape receiving assembly 501 of the second rubberizing mechanism 530 are close to each other again, and the first suction block 5261 and the second suction block 5262 of the first rubberizing mechanism 529 suck the standby tape. The standby tape is cut off by the second cutter 531, and then the second adsorption block 5262 of the first rubberizing mechanism 529 stops adsorbing, and the second adsorption block 5262 of the second rubberizing mechanism 530 starts adsorbing the starting end of the standby tape. At this time, the working material belt and the standby material belt are both absorbed by the second absorbing part 526 of the second rubberizing mechanism 530, and since the cutting position of the second cutter 531 to the standby material belt is fixed, the distance between the tail end of the working material belt and the starting end of the standby material belt is also fixed, the distance between the tail end and the starting end can be regarded as equal to the thickness of the second cutter 531, the subsequent tape splicing can be more accurate, and the product consistency is good. Then, the tape splicing component 501 of the first rubberizing mechanism 529 and the tape splicing component 501 of the second rubberizing mechanism 530 are far away from each other, the rubberizing piece 525 of the first rubberizing mechanism 529 is turned over, the first adsorbing piece 527 of the first rubberizing mechanism 529 faces the second adsorbing piece 526 of the second rubberizing mechanism 530, the first adsorbing piece 5261 of the first rubberizing mechanism 529 stops adsorbing, and a cut section of the standby tape falls. Then, the tape splicing assembly 501 of the first rubberizing mechanism 529 and the tape splicing assembly 501 of the second rubberizing mechanism 530 are close to each other, and the adhesive tape on the first suction member 527 of the first rubberizing mechanism 529 adheres the tail end of the working material tape on the second suction member 526 of the second rubberizing mechanism 530 and the head end of the spare material tape together. Next, the tape splicing component 501 of the first rubberizing mechanism 529 and the tape splicing component 501 of the second rubberizing mechanism are far away from each other, the rubberizing component 525 of the first rubberizing mechanism 529 is turned over to restore to a glue preparation state, and at this time, the first adhesive attachment 527 can be prepared again. Then, the tape splicing assembly 501 of the first rubberizing mechanism 529 and the tape splicing assembly 501 of the second rubberizing mechanism are close to each other, the second suction member 526 of the first rubberizing mechanism 529 is vacuumized, the second suction member 526 of the second rubberizing mechanism 530 stops vacuuming, and the tape is sucked to the first rubberizing mechanism 529. Then, the tape splicing component 501 of the first rubberizing mechanism 529 and the tape splicing component 501 of the second rubberizing mechanism 530 are far away from each other, the rubberizing piece 525 of the second rubberizing mechanism 530 is turned over, and then the two tape splicing components 501 are close again, so that the adhesive tape absorbed by the first absorbing component 527 of the second rubberizing mechanism 530 is adhered to the other sides of the working material tape and the standby material tape, and the tail end of the working material tape and the head end of the standby material tape are adhered together. Finally, the first rubberizing mechanism 529 and the second rubberizing mechanism 530 do not adsorb the material belt any more, and both sides of the material belt are adhered by the adhesive tape, so that the reel replacement is completed.
