Description

[0001] This application is a divisional application of application number CN202520283492.3, filed on February 21, 2025, entitled "A waste material removal mechanism, a roll changing device and a winding device". Technical Field

[0002] This application relates to the field of battery manufacturing equipment technology, specifically a waste material removal mechanism, a winding device, and a winding equipment. Background Technology

[0003] In the battery manufacturing process, it is often necessary to continuously unwind and output the material strip on the roll downstream. For example, in the cell winding process, electrode sheets need to be continuously unwound and output to the winding device. When the working material strip on the working roll is unwound, it needs to be cut and then connected to the spare material strip of the spare roll, so that the material strip can continue to be unwound and output downstream, thus completing the roll change.

[0004] In the existing technology, in order to align the end of the spare material strip with the end of the working material strip, the starting end of the spare material strip needs to be cut off before each connection. The cut starting end of the spare material strip is waste material, which needs to be manually removed, greatly reducing production efficiency. Utility Model Content

[0005] Therefore, it is necessary to provide a waste collection mechanism, a roll changing device, and a winding device that can automatically collect waste materials, improve production efficiency and automation, and address the above-mentioned problems.

[0006] A waste removal mechanism is used to remove waste rolls wound on take-up rollers, the waste removal mechanism comprising: The waste removal assembly includes a moving seat, a first clamping block and a second clamping block. The first clamping block and the second clamping block are disposed on the moving seat. A receiving space is formed between the first clamping block and the second clamping block for the receiving roller to enter. The first clamping block and the second clamping block can be controlled to move closer to or further away from each other. Pushing parts are provided on the sides of the first clamping block and the second clamping block that face each other. The motion seat can be controlled to move along the axial direction of the take-up roller, so as to drive each of the pusher parts to push the waste roll on the take-up roller to detach from the take-up roller axially and enter the receiving space.

[0007] In some embodiments, the first clamping block and the second clamping block are each provided with a support portion on their sides facing each other, and each of the support portions is used to support the waste roll that has detached from the take-up roller.

[0008] In some embodiments, the waste removal mechanism further includes a drive assembly, the motion seat is mounted on the drive end of the drive assembly, and the drive assembly is used to drive the motion seat to move to the waste removal position and the waste release position.

[0009] In some embodiments, the waste collection assembly further includes a mounting base and a second drive member. The mounting base is mounted on the drive end of the drive assembly, and the motion seat is movably connected to the mounting base along a third direction that is aligned with the axial direction of the receiving roller. The second drive member is mounted on the mounting base, and the drive end of the second drive member is connected to the motion seat.

[0010] In some embodiments, the drive component is used to drive the mounting base to move along a first direction and / or a second direction, and the second drive member is used to drive the motion seat to move along the third direction; wherein the first direction, the second direction, and the third direction intersect each other.

[0011] In some embodiments, the drive assembly includes a translation drive, a third drive, a first transfer seat, a fourth drive, and a second transfer seat; The third driving member is installed on the driving end of the translation driving member, the first transfer seat is installed on the driving end of the third driving member, the fourth driving member is installed on the first transfer seat, the second transfer seat is movably connected to the first transfer seat and connected to the driving end of the fourth driving member, and the mounting seat is installed on the second transfer seat.

[0012] In some embodiments, the translational drive is used to drive the third drive to move along a first direction, the third drive is used to drive the first transfer seat to move along the third direction, and the fourth drive is used to drive the second transfer seat to move along a second direction.

[0013] In some embodiments, each of the pusher portions includes an elastic element and a pusher post. The first clamping block and the second clamping block each have mounting holes on their sides facing each other. A portion of the pusher post passes through the mounting hole. The elastic element is disposed in the mounting hole and abuts against the portion of the pusher post located in the mounting hole to provide a preload force that causes the pusher post to have a tendency to move out of the mounting hole.

[0014] In some embodiments, the pusher is a spring plunger.

[0015] In some embodiments, the first clamping block is provided with a plurality of the support portions, and the plurality of the support portions on the first clamping block are arranged at intervals along the axial direction of the receiving roller.

[0016] In some embodiments, the second clamping block is provided with a plurality of the support portions, and the plurality of the support portions located on the second clamping block are arranged at intervals along the axial direction of the take-up roller; In the arrangement direction of the first clamping block and the second clamping block, the respective support portions on the first clamping block and the respective support portions on the second clamping block are arranged in a staggered manner.

[0017] In some embodiments, the waste removal assembly further includes a gripper cylinder mounted on the motion seat, with the first gripper block and the second gripper block respectively mounted on the two drive ends of the gripper cylinder, and the gripper cylinder used to drive the first gripper block and the second gripper block closer to or further away from each other.

[0018] A roll changing device includes a waste material removal mechanism as described in any of the above embodiments.

[0019] A winding apparatus includes a winding device as described in any of the above embodiments.

[0020] When the aforementioned waste material removal mechanism, roll changing device, and winding equipment need to remove the waste roll from the take-up roller, firstly, the waste material removal assembly moves to the waste material removal position, aligning the take-up roller with the receiving space between the first clamp and the second clamp. Then, the waste material removal assembly drives the first and second clamps closer to the take-up roller, causing the take-up roller and its waste roll to enter the receiving space between the first and second clamps until the pusher on the first and / or second clamps reaches the far end of the waste roll. Next, the first drive member drives the first and second clamps closer together until the pusher on the first and / or second clamps abuts against the far end face of the waste roll. Then, the first and second clamps move away from the take-up roller, thereby driving the pusher to push the waste roll on the take-up roller axially until the waste roll detaches from the take-up roller and enters the receiving space. Then, the first and second clamping blocks continue to move closer to each other to clamp the waste roll, thus preventing it from loosening and facilitating its transfer. This allows for the automatic removal of waste rolls from the take-up rollers, eliminating the need for manual waste removal, significantly improving production efficiency and automation, and reducing labor costs.

[0028] Please see Figure 1 and Figure 2 This application provides a roll changing device, including a glue preparation mechanism 10, a material preparation mechanism 20, an unwinding mechanism 31, a tape splicing mechanism 30, a glue taking mechanism 42, a material taking mechanism 43, and a waste material taking mechanism.

[0029] The adhesive preparation mechanism 10 provides adhesive tape, and the material preparation mechanism 20 provides spare rolls A1. The waste removal mechanism includes a drive assembly 41, with adhesive removal mechanism 42 and material removal mechanism 43 both mounted on the drive end of the drive assembly 41. The drive assembly 41 drives the adhesive removal mechanism 42 and material removal mechanism 43 to move, allowing the adhesive removal mechanism 42 to move to the adhesive preparation mechanism 10 and the tape receiving mechanism 30, and the material removal mechanism 43 to move to the material preparation mechanism 20 and the unwinding mechanism 31. When the adhesive removal mechanism 42 moves to the adhesive preparation mechanism 10, it can pick up the adhesive tape provided by the adhesive preparation mechanism 10; when the adhesive removal mechanism 42 moves to the tape receiving mechanism 30, it can release the picked-up adhesive tape to the tape receiving mechanism 30. That is, the adhesive removal mechanism 42 can transfer the adhesive tape provided by the adhesive preparation mechanism 10 to the tape receiving mechanism 30. When the picking mechanism 43 moves to the preparation mechanism 20, it can pick up the spare material roll A1 provided by the preparation mechanism 20. When the picking mechanism 43 moves to the unwinding mechanism 31, it can release the picked-up spare material roll A1 to the unwinding mechanism 31. That is, the picking mechanism 43 can transfer the spare material roll A1 provided by the preparation mechanism 20 to the unwinding mechanism 31.

[0030] The unwinding mechanism 31 is used to load the working material roll and the spare material roll A1, and drives the working material roll to rotate, thereby unwinding and outputting the working material tape downstream. The tape splicing mechanism 30 is arranged downstream of the unwinding mechanism 31 to receive the tape transferred by the adhesive dispensing mechanism 42, and cuts the working material tape when the working material roll on the unwinding mechanism 31 is unwound, and then attaches the tape between the downstream cut end of the working material tape and the spare material tape A2 of the spare material roll A1, thereby realizing the connection between the working material tape and the spare material tape A2, that is, realizing tape splicing.

[0031] In the actual roll changing operation, the drive assembly 41 drives the material handling mechanism 43 to transfer the spare roll A1 provided by the material preparation mechanism 20 to the unwinding mechanism 31. The drive assembly 41 also drives the adhesive handling mechanism 42 to transfer the adhesive tape provided by the adhesive preparation mechanism 10 to the tape receiving mechanism 30. When the working roll on the unwinding mechanism 31 is used up, the tape receiving mechanism 30 cuts the working tape and uses adhesive tape to bond the downstream cut end of the working tape to the spare roll A2 on the spare roll A1, thus connecting the spare roll A2 to the working tape. At this time, the spare roll A1 on the tape receiving mechanism 30 is switched to a working roll and continues to unwind and output the working tape downstream.

[0032] Thus, the roll changing device of this application can automatically complete the processes of transferring the tape, transferring the spare roll A1, and bonding the downstream cut end of the working tape with the spare roll A2, thereby realizing automatic roll changing without the need for manual processing of the tape and spare roll A1. This is beneficial to improving the automation level of the roll changing equipment, increasing the roll changing efficiency, eliminating the need for personnel on duty, and reducing labor costs.

[0033] In the embodiments of this application, the tape-joining mechanism 30 includes a tape-joining assembly 32 and a waste material collection assembly 33, both arranged downstream of the unwinding mechanism 31. The waste material collection assembly 33 has a take-up roller 331. The unwinding mechanism 31 is used to unwind the working tape to the tape-joining assembly 32 and receive the spare tape roll A1 transferred by the take-up mechanism 43. The adhesive take-up mechanism 42 is also used to use adhesive tape to pick up the starting end A3 of the spare tape roll A1 on the unwinding mechanism 31 and pull the starting end A3 of the tape to pass sequentially through the tape-joining assembly 32 and the waste material collection assembly 33, so that the take-up roller 331 of the waste material collection assembly 33 can fix the spare tape A2, preparing for subsequent roll changing. The tape-joining assembly 32 is used to cut the working tape and the spare tape A2 that are passing through, and uses adhesive tape to bond the downstream cut end of the working tape and the upstream cut end of the spare tape A2, thereby realizing the interconnection between the downstream cut end of the working tape and the upstream cut end of the spare tape A2, that is, realizing tape joining.

[0034] Thus, in actual use, firstly, the drive assembly 41 drives the glue-taking mechanism 42 to move to the glue preparation mechanism 10, so that the glue-taking mechanism 42 picks up the tape provided by the glue preparation mechanism 10 at the glue preparation mechanism 10. Then, the drive assembly 41 drives the glue-taking mechanism 42 to move to the unwinding mechanism 31, so that the glue-taking mechanism 42 uses the tape to pick up the starting end A3 of the spare roll A1 on the unwinding mechanism 31. Then, the drive assembly 41 drives the glue-taking mechanism 42 to pass through the tape-connecting assembly 32 and the waste-collecting assembly 33 in sequence, thereby pulling out the spare material tape A2 on the spare material roll A1. The pulled-out spare material tape A2 passes through the tape-connecting assembly 32 and the waste-collecting assembly 33 in sequence and is fixed on the take-up roller 331 of the waste-collecting assembly 33. On the one hand, this allows the tape-connecting assembly 32 to cut the working material tape and the spare material tape A2 at the same time when changing rolls. On the other hand, after the spare material tape A2 is cut, the part between the tape-connecting assembly 32 and the waste-collecting assembly 33 becomes waste. The take-up roller 331 of the waste-collecting assembly 33 can rewind the waste and form a waste roll A4, avoiding interference from the tape-connecting action of the tape-connecting assembly 32.

[0035] It is understandable that the unwinding mechanism 31, the tape receiving assembly 32, and the waste collection assembly 33 cooperate to cut the working tape and the spare tape A2, and use adhesive tape to bond the downstream cut end of the working tape and the upstream cut end of the spare tape A2. This is a relatively mature existing technology, so it will not be described in detail here.

[0036] It is important to emphasize that after the working conveyor belt is cut, two cut ends are formed at the break point. The one located upstream is the upstream cut end, and the one located downstream is the downstream cut end. Similarly, after the spare conveyor belt A2 is cut, two cut ends are formed at the break point. The one located upstream is the upstream cut end, and the one located downstream is the downstream cut end. In this article, upstream and downstream refer to the conveyor belt's path. The location where the conveyor belt arrives first is upstream, and the location where the conveyor belt arrives later is downstream.

[0037] It should be noted that after the splicing assembly 32 cuts the working material strip, the part of the working material strip between the splicing assembly 32 and the unwinding mechanism 31 is also waste material. The unwinding mechanism 31 can be used to rewind this part of waste material to avoid this part of waste material interfering with the splicing operation of the splicing assembly 32.

[0038] Please see Figure 1 , Figures 3 to 5In embodiments of this application, the waste removal mechanism further includes a waste box 50 and a waste removal component 44 mounted on the drive end of the drive assembly 41. The drive assembly 41 is also used to drive the waste removal component 44 to move to the receiving roller 331 of the waste receiving assembly 33 and the waste box 50. When the drive assembly 41 drives the waste removal component 44 to move to the receiving roller 331 of the waste receiving assembly 33, the waste removal component 44 can remove the waste roll A4 from the receiving roller 331 of the waste receiving assembly 33. When the drive assembly 41 drives the waste removal component 44 to move to the waste box 50, the waste removal component 44 can release the waste roll A4 into the waste box 50.

[0039] Specifically, in this embodiment, the waste removal assembly 44 includes a first drive member 4451, a first clamping block 4453, and a second clamping block 4455. A receiving space j is formed between the first clamping block 4453 and the second clamping block 4455 to allow the take-up roller 331 to enter. The first clamping block 4453 and the second clamping block 4455 are mounted on the moving end of the first drive member 4451, enabling the first drive member 4451 to drive the first clamping block 4453 and the second clamping block 4455 to move closer or further apart to clamp or release the waste roll A4. Pushing portions 4457 are provided on the sides of the first clamping block 4453 and the second clamping block 4455 facing each other. The drive assembly 41 is also used to drive the entire waste removal assembly 44 to move axially along the take-up roller 331, thereby causing the pushing portions 4457 to push the waste roll A4 on the take-up roller 331 axially and disengage from the take-up roller 331, thus entering the receiving space j.

[0040] Furthermore, support portions 4459 are provided on the sides of the first clamping block 4453 and the second clamping block 4455 facing each other. Each support portion 4459 is capable of supporting the waste roll A4 that has detached from the take-up roller 331 and is located in the receiving space j.

[0041] Thus, when it is necessary to remove the waste roll A4 from the take-up roller 331, firstly, the drive assembly 41 drives the waste removal assembly 44 to move to the waste removal position, so that the receiving space j between the take-up roller 331 of the waste removal assembly 33 and the first clamping block 4453 and the second clamping block 4455 is opposite in the third direction X3, which is aligned with the axial direction of the take-up roller 331. Then, the drive assembly 41 drives the waste removal assembly 44 to move closer to the take-up roller 331 along the third direction X3, thereby driving the first clamping block 4453 and the second clamping block 4455 to move closer to the take-up roller 331 along the third direction X3, so that the take-up roller 331 and the waste roll A4 on it enter the receiving space j between the first clamping block 4453 and the second clamping block 4455, until the pushing part 4457 on the first clamping block 4453 and the pushing part 4457 on the second clamping block 4455 reach the far end A41 of the waste roll A4 (see Figure 5Then, the first drive member 4451 drives the first clamping block 4453 and the second clamping block 4455 to move closer to each other until the pushing part 4457 on the first clamping block 4453 and the pushing part 4457 on the second clamping block 4455 can abut against the end face of the far end A41 of the waste roll A4. Next, the drive assembly 41 drives the waste-taking assembly 44 to move away from the take-up roller 331 along a third direction X3, thereby causing the pushing part 4457 to push the waste roll A4 on the take-up roller 331 axially until the waste roll A4 disengages from the take-up roller 331 and is supported by the various support parts 4459 between the first clamping block 4453 and the second clamping block 4455. Then, the first drive member 4451 drives the first clamping block 4453 and the second clamping block 4455 to continue moving closer to each other to clamp the waste roll A4, thereby preventing the waste roll A4 from loosening. Next, the drive assembly 41 drives the waste retrieval assembly 44 to move to the waste placement position, so that the first clamping block 4453 and the second clamping block 4455 are positioned above the waste box 50. Finally, the first drive member 4451 drives the first clamping block 4453 and the second clamping block 4455 away from each other until the waste roll A4 between the first clamping block 4453 and the second clamping block 4455 falls into the waste box 50.

[0042] Furthermore, the first clamping block 4453 is provided with a plurality of support portions 4459, which are spaced apart along the axial direction of the take-up roller 331. The second clamping block 4455 is provided with a plurality of support portions 4459, which are spaced apart along the axial direction of the take-up roller 331. In this way, the plurality of support portions 4459 on the first clamping block 4453 and the plurality of support portions 4459 on the second clamping block 4455 work together to support the waste roll A4 entering the receiving space j, preventing the waste roll A4 from falling off.

[0043] Furthermore, in the arrangement direction of the first clamping block 4453 and the second clamping block 4455, the support portions 4459 on the first clamping block 4453 and the support portions 4459 on the second clamping block 4455 are staggered, so that when the first clamping block 4453 and the second clamping block 4455 are close to each other to clamp the waste roll A4, the support portions 4459 on the first clamping block 4453 and the support portions 4459 on the second clamping block 4455 are avoided from colliding.

[0044] It should be noted that the support portion 4459 on the first clamping block 4453 and the second clamping block 4455 is not essential. In some embodiments, the support portion 4459 may not be provided on the first clamping block 4453 and the second clamping block 4455. The waste roll A4, which has detached from the take-up roller 331 and entered the receiving space j, is directly clamped and fixed by the first clamping block 4453 and the second clamping block 4455. In still other embodiments, the support portion 4459 is not provided on the first clamping block 4453 and the second clamping block 4455 either. The first clamping block 4453 and the second clamping block 4455 are arranged vertically such that the waste roll A4, which has detached from the take-up roller 331 and entered the receiving space j, is supported on the lower one of the first clamping block 4453 and the second clamping block 4455. For ease of understanding, this article uses an embodiment in which both the first clamping block 4453 and the second clamping block 4455 are provided as an example for explanation.

[0045] Furthermore, the first driving component can be a gripper cylinder. The first gripper block 4453 and the second gripper block 4455 are respectively mounted on the two driving ends of the gripper cylinder. The gripper cylinder is used to drive the first gripper block 4453 and the second gripper block 4455 to move closer to or further away from each other.

[0046] Furthermore, each pusher portion 4457 includes an elastic element (not shown) and a pusher post (not indicated). Mounting holes are provided on the sides of the first clamping block 4453 and the second clamping block 4455 facing each other. A portion of the pusher post passes through the corresponding mounting hole, while another portion is located in the space between the first clamping block 4453 and the second clamping block 4455, and the pusher post is axially movable along the mounting hole. The elastic element is disposed within the corresponding mounting hole and abuts against the portion of the pusher post located within the mounting hole, providing a preload force that causes the pusher post to tend to move outward from the mounting hole. Thus, when the first clamping block 4453 and the second clamping block 4455 approach each other and clamp the waste roll A4, even if the pusher post on the first clamping block 4453 and the pusher post on the second clamping block 4455 abut against each other, the elastic element provides elasticity, preventing damage and interference with the clamping action of the first clamping block 4453 and the second clamping block 4455. Similarly, when the first clamping block 4453 and the second clamping block 4455 approach each other and clamp the waste roll A4, even if the pusher on the first clamping block 4453 abuts against the second clamping block 4455, or even if the pusher on the second clamping block 4455 abuts against the first clamping block 4453, the elastic element will not cause damage, nor will it interfere with the clamping action of the first clamping block 4453 and the second clamping block 4455. Optionally, the pusher part 4457 can be a spring plunger. The spring plunger is a standard part, which helps to reduce equipment costs.

[0047] Specifically, in this embodiment, the waste collection assembly 44 further includes a mounting base 441 and a second driving member 442. The mounting base 441 is mounted on the driving end of the driving assembly 44, enabling the driving assembly 44 to drive the mounting base 441 to move along a first direction X1 and / or a second direction X2. A moving seat 443 is movably connected to the mounting base 441 along a third direction X3. The second driving member 442 is mounted on the mounting base 441, and the driving end of the second driving member 442 is connected to the moving seat 443, enabling the second driving member 442 to drive the moving seat 443 to move relative to the mounting base 441 along a third direction X3. The third direction X3 is aligned with the axial direction of the receiving roller 331.

[0048] Specifically, in the embodiments, the driving component 41 includes a translational driving element 411 (see...). Figure 1 The system comprises a third driving member 412, a first transfer seat 413, a fourth driving member 414, and a second transfer seat 415. The third driving member 412 is mounted on the driving end of the translation driving member 411, enabling the translation driving member 411 to drive the third driving member 412 to move along a first direction X1. The first transfer seat 413 is mounted on the driving end of the third driving member 412, enabling the third driving member 412 to drive the first transfer seat 413 to move along a third direction X3. The fourth driving member 414 is mounted on the first transfer seat 413, enabling the fourth driving member 414 to move together with the first transfer seat 413. The second transfer seat 415 is movably connected to the first transfer seat 413 along a second direction X2 and is connected to the driving end of the fourth driving member 414, enabling the fourth driving member 414 to drive the second transfer seat 415 to move relative to the first transfer seat 413 along the second direction X2. The aforementioned mounting base 441 is mounted on the second transfer base 415 of the drive assembly 41, enabling the mounting base 441 to move along the first direction X1, the second direction X2, and the third direction X3 together with the second transfer base 415. It should be noted that the translation drive unit 411, the third drive unit 412, and the fourth drive unit 414 can be linear drive modules such as cylinders, electric cylinders, or synchronous belt drive mechanisms, as long as they can achieve accurate movement of the waste material removal assembly 44; no limitation is imposed here.

[0049] Thus, the second transfer seat 415 drives the mounting seat 441 to move along the first direction X1, the second direction X2, and / or the third direction X3, thereby moving the first clamping block 4453 and the second clamping block 4455 to the receiving roller 331 or the waste box 50. When the first clamping block 4453 and the second clamping block 4455 move to the receiving roller 331, the second driving member 442 drives the moving seat 443 to move along the third direction X3, so that the receiving roller 331 first enters and then exits between the first clamping block 4453 and the second clamping block 4455, thereby causing the waste roll A4 on the receiving roller 331 to separate from the receiving roller 331 under the pushing action of the pushing part 4457.

[0050] Furthermore, a second slide rail is provided on the first transfer seat 413, which extends longitudinally along the second direction X2. The second transfer seat 415 is slidably disposed on the second slide rail, thereby guiding the movement of the second transfer seat 415 relative to the first transfer seat 413 along the second direction X2.

[0051] Based on the aforementioned rewinding device, this application also provides a winding apparatus, which includes a winding device and a rewinding device as described in any of the above embodiments. The rewinding device is used to unwind the working strip output from the winding device, and the winding device is used to wind the working strip output from the rewinding device to form a battery cell. It should be noted that the working strip can be a positive electrode sheet or a negative electrode sheet, and of course, it can also be other types of strips, which are not limited here.

[0052] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0053] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
