Description

Technical Field

[0001] This application relates to the field of battery manufacturing equipment technology, specifically a transfer mechanism, a winding device, and a winding equipment. Background Technology

[0002] 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.

[0003] In the existing technology, in order to connect the working material strip and the spare material strip, manual handling of the material rolls and loading and unloading of the rolls are required. This results in a low degree of automation of the roll changing device, requires personnel to be on duty, increases labor costs, and reduces production efficiency. Utility Model Content

[0060] Please see Figure 1 This application provides a roll changing device, including a glue preparation mechanism 10, a tape receiving mechanism 30, a transfer mechanism 40, a glue taking mechanism 42, and an unwinding mechanism 31.

[0061] The adhesive preparation mechanism 10 is used to provide adhesive tape e (see...) Figure 2 The adhesive dispensing mechanism 42 is used to transfer the adhesive tape e provided by the adhesive preparation mechanism 10 to the tape receiving mechanism 30. The transfer mechanism 40 is used to transfer the spare material roll A1 to the unwinding mechanism 31. The unwinding mechanism 31 is used to load the working material roll and the spare material roll A1, and drive the working material roll downstream to unwind and output the working material tape. The tape receiving mechanism 30 is arranged downstream of the unwinding mechanism 31 and is used to receive the adhesive tape e transferred by the adhesive dispensing mechanism 42. The tape receiving mechanism 30 is also used to cut the working material tape when the working material roll on the unwinding mechanism 31 is unwound, and use the adhesive tape e to bond the downstream cut end of the working material tape to 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 receiving.

[0062] Furthermore, the transfer mechanism 40 includes a material preparation component 20, a material taking component 43, and a drive component 41. The material preparation component 20 is used to provide spare material rolls A1. The material taking component 43 is mounted on the drive end of the drive component 41, and the drive component 41 is used to drive the material taking component 43 to move between the material preparation component 20 and the unwinding mechanism 31. When the drive component 41 drives the material taking component 43 to the material preparation component 20, the material taking component 43 can receive the spare material roll A1 provided by the material preparation component 20. When the drive component 41 drives the material taking component 43 to the unwinding mechanism 31, the material taking component 43 can transfer the spare material roll A1 onto the unwinding mechanism 31.

[0063] Furthermore, the adhesive dispensing mechanism 42 is also installed at the drive end of the drive assembly 41. The drive assembly 41 is also used to drive the adhesive dispensing mechanism 42 to move to the adhesive preparation mechanism 10 and the tape receiving mechanism 30. When the drive assembly 41 drives the adhesive dispensing mechanism 42 to the adhesive preparation mechanism 10, the adhesive dispensing mechanism 42 can pick up the tape e provided by the adhesive preparation mechanism 10. When the drive assembly 41 drives the adhesive dispensing mechanism 42 to the tape receiving mechanism 30, the adhesive dispensing mechanism 42 can transfer the picked-up tape e to the tape receiving mechanism 30. Thus, the adhesive dispensing mechanism 42 and the material picking assembly 43 share the same drive assembly 41, which is beneficial for reducing device costs compared to a scheme where each has its own drive component. Of course, in other embodiments, the adhesive dispensing mechanism 42 may not be installed at the drive end of the drive assembly 41. Instead, a drive component may be configured for the adhesive dispensing mechanism 42, and this drive component can be used to drive the adhesive dispensing mechanism 42 to move, as long as the transfer of tape e can be completed. This is not a limitation. For ease of understanding, this article will use the embodiment in which the glue dispensing mechanism 42 is installed on the drive end of the drive assembly 41 as an example for explanation.

[0064] In the actual roll changing operation, the drive assembly 41 drives the material taking assembly 43 to transfer the spare roll A1 provided by the material preparation assembly 20 to the unwinding mechanism 31. The drive assembly 41 also drives the adhesive taking mechanism 42 to transfer the adhesive tape e 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 the adhesive tape e to bond the downstream cut end of the working tape to the spare roll A2 on the spare roll A1, thereby connecting the spare roll A2 with the working tape. At this time, the spare roll A1 on the unwinding mechanism 31 is switched to a working roll, and the working tape continues to be unwound and output downstream.

[0065] Thus, the roll changing device of this application can automatically complete the transfer of tape e, the transfer of spare roll A1, and the bonding of the downstream cut end of the working tape with the spare roll A2, thereby realizing automatic roll changing. There is no need for manual processing of tape e and spare roll A1, which helps to improve the automation level of the roll changing equipment, improve the roll changing efficiency, and reduce labor costs by eliminating the need for personnel to be on duty.

[0066] In the embodiments of this application, the tape splicing mechanism 30 includes a tape splicing assembly 32 and a waste material collection assembly 33, both arranged downstream of the unwinding mechanism 31. The unwinding mechanism 31 is used to unwind the working tape to the tape splicing assembly 32 and receive the spare tape roll A1 transferred by the material collection assembly 43. The adhesive collection mechanism 42 is also used to use adhesive tape e to pick up the starting end A3 of the spare tape roll A1 on the unwinding mechanism 31, and to pull the starting end A3 of the tape roll A1 through the tape splicing assembly 32 and the waste material collection assembly 33 in sequence, so that the waste material collection assembly 33 can fix the spare tape roll A2, preparing for subsequent roll changing. The tape splicing assembly 32 is used to cut the working tape and the spare tape roll A2, and to use adhesive tape e to bond the downstream cut end of the working tape and the upstream cut end of the spare tape roll A2, thereby realizing the interconnection between the downstream cut end of the working tape and the upstream cut end of the spare tape roll A2, that is, realizing tape splicing.

[0067] 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 e provided by 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 e 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 tape A2 on the spare tape roll A1. The pulled-out spare tape A2 passes through the tape-connecting assembly 32 and the waste-collecting assembly 33 in sequence and is fixed on the waste-collecting assembly 33. On the one hand, this allows the tape-connecting assembly 32 to cut the working tape and the spare tape A2 at the same time when changing rolls. On the other hand, after the spare tape A2 is cut, the part between the tape-connecting assembly 32 and the waste-collecting assembly 33 becomes waste. 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.

[0068] 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 tape e 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.

[0069] 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.

[0070] 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.

[0071] Please see Figures 1 to 3 As shown, in a specific embodiment, the glue-taking mechanism 42 has a glue-absorbing roller 421 that can rotate around its own axis. The glue-taking mechanism 42 can use the glue-absorbing roller 421 to fix the starting end of the tape e at the glue preparation mechanism 10 and wind the tape e. The glue preparation mechanism 10 is used to cut the tape e, so that a certain length of tape e is wound on the glue-absorbing roller 421.

[0072] It should be noted that in the prior art, a certain length of tape e is pulled out onto the suction plate using a tape-pulling mechanism, and then the pulled-out tape e is cut off. The tape e on the suction plate is then transferred to a designated position. Compared with the prior art, this embodiment uses a suction roller 421 to fix the starting end of the tape e, and then winds a certain length of tape e before cutting it, thereby achieving the pickup and transfer of the tape e. This eliminates the need for a tape-pulling mechanism to pull the tape and for the suction plate to absorb the tape, greatly saving space and resulting in a more compact structure. This makes the roll-changing device more adaptable to space-constrained working conditions.

[0073] Please see Figure 4 Furthermore, the tape-attaching assembly 32 has an adhesive-absorbing surface f for adsorbing the tape e. The adhesive-taking mechanism 42 can move to the tape-attaching assembly 32 under the driving action of the driving assembly 41, causing the adhesive-absorbing roller 421 to abut against the adhesive-absorbing surface f, thereby causing the adhesive-absorbing surface f to adsorb the tape e on the adhesive-absorbing roller 421. The adhesive-taking mechanism 42 can also drive the adhesive-absorbing roller 421 to roll along the adhesive-absorbing surface f under the driving action of the driving assembly 41, thereby causing the tape e to be flattened and laid on the adhesive-absorbing surface f until the tape e is completely separated from the adhesive-absorbing roller 421, thus achieving the transfer of the tape e to the adhesive-absorbing surface f of the tape-attaching assembly 32.

[0074] Please see Figure 5Furthermore, the adhesive-taking mechanism 42 can also use the adhesive suction roller 421 to abut against the spare material roll A1 on the unwinding mechanism 31, so that the adhesive strip e on the adhesive suction roller 421 is bonded to the starting end A3 of the material strip on the spare material roll A1, and the spare material strip A2 is wound around it by its own rotation. The adhesive-taking mechanism 42 can also use the adhesive suction roller 421 to pull the starting end A3 of the material strip through the tape receiving assembly 32 and the waste material collection assembly 33 in sequence, so that the spare material strip A2 of the spare material roll A1 passes through the tape receiving assembly 32 and is fixed on the waste material collection assembly 33.

[0075] It should be noted that the two sides of the tape e are the adhesive side and the non-adhesive side, respectively. Therefore, the orientation of the adhesive side of the tape e wound on the suction roller 421 can be controlled by adjusting the rotation direction of the suction roller 421. That is, when the suction roller 421 is controlled to rotate in the first direction (i.e., Figure 2 When rotating counterclockwise in the illustrated embodiment, the adhesive side of the tape e wound on the suction roller 421 is located on the outer side and does not contact the suction roller 421, while the non-adhesive side is located on the inner side and contacts the roller surface of the suction roller 421. When the suction roller 421 is controlled to rotate in a second direction (opposite to the first direction), the adhesive side of the tape e wound on the suction roller 421 is located on the inner side and contacts the roller surface of the suction roller 421, while the non-adhesive side is located on the outer side and does not contact the suction roller 421.

[0076] When it is necessary to pick up the starting end A3 of the tape on the spare roll A1, the drive assembly 41 drives the glue-picking mechanism 42 to move to the glue preparation mechanism 10, so that the glue-absorbing roller 421 fixes the starting end of the tape e. The glue-absorbing roller 421 is controlled to rotate in the first direction of rotation until a certain length of tape e is wound onto the glue-absorbing roller 421. Then, the glue preparation mechanism 10 is controlled to cut the tape e. Then, the drive assembly 41 drives the glue-picking mechanism 42 to move to the unwinding mechanism 31, so that the glue-absorbing roller 421 presses against the starting end A3 of the tape on the spare roll A1. At this time, since the adhesive surface of the tape e on the glue-absorbing roller 421 is on the outside, the tape e and the starting end A3 of the tape on the spare roll A1 are bonded and fixed to each other. Then, the glue-absorbing roller 421 rotates around its own axis, thereby driving the spare tape A2 on the spare roll A1 to be wound onto the glue-absorbing roller 421. Then, driven by the drive assembly 41, the suction roller 421 pulls the spare material strip A2 on the spare material roll A1 through the tape receiving assembly 32 and the waste material collection assembly 33 in sequence, and the waste material collection assembly 33 fixes the passing spare material strip A2. Finally, the suction roller 421 is controlled to rotate in the second direction until the starting end A3 of the spare material strip A2 and the tape e are completely separated from the suction roller 421.

[0077] When it is necessary to transfer tape e to the adhesive-absorbing surface f of the tape-connecting assembly 32, the drive assembly 41 drives the adhesive-taking mechanism 42 to move to the adhesive preparation mechanism 10, so that the adhesive-absorbing roller 421 fixes the starting end of tape e. The adhesive-absorbing roller 421 is controlled to rotate in the second direction of rotation until a certain length of tape e is wound onto the adhesive-absorbing roller 421. At this time, the adhesive-containing surface of tape e on the adhesive-absorbing roller 421 is located on the inner side. Then, the adhesive preparation mechanism 10 is controlled to cut tape e. Then, the drive assembly 41 drives the adhesive-taking mechanism 42 to move to the tape-connecting assembly 32, so that the adhesive-absorbing roller 421 presses against the adhesive-absorbing surface f. Then, under the driving action of the drive assembly 41, the adhesive-absorbing roller 421 rolls along the adhesive-absorbing surface f, and the rotation direction of the adhesive-absorbing roller 421 is the first direction of rotation, until the tape e is completely flattened and laid on the adhesive-absorbing surface f and completely separated from the adhesive-absorbing roller 421. At this time, the adhesive side of tape e is away from the adhesive absorption surface f, and the non-adhesive side of tape e faces the adhesive absorption surface f and is adsorbed and fixed by the adhesive absorption surface f, so that the tape e can be pasted between the downstream cut end of the working material tape and the upstream cut end of the spare material tape A2 in the future.

[0078] Please see Figures 11 to 14 Specifically, in this embodiment, the waste collection assembly 33 includes a first moving base 334, a second rotary drive 336, and a collection roller 331. The second rotary drive 336 is mounted on the first moving base 334 to move together with it. The collection roller 331 is mounted on the first moving base 334 and connected to the drive end of the second rotary drive 336, enabling the second rotary drive 336 to drive the collection roller 331 to rotate around its own axis.

[0079] The take-up roller 331 has an insertion slot k. The first moving seat 334 can controllably drive the take-up roller 331 to move along its own axis so that the spare material strip A2, which follows the suction roller 421 to the waste collection assembly 33, enters the insertion slot k. After the spare material strip A2 enters the insertion slot k of the take-up roller 331, the second rotary drive 336 drives the take-up roller 331 to rotate, thereby causing the spare material strip A2 to be wound around the take-up roller 331. Optionally, the second rotary drive 336 can be a motor.

[0080] Thus, in actual use, firstly, the first moving seat 334 drives the receiving roller 331 to move along its own axis (i.e., as shown in the image). Figure 1 (As shown, moving inward along the paper surface direction) to the avoidance position, thereby preventing the take-up roller 331 from interfering with the suction roller 421 when the suction roller 421 pulls the starting end A3 of the spare material strip A2. Then, the suction roller 421 pulls the starting end A3 of the spare material strip A2 on the spare material roll A1 through the tape receiving assembly 32 and the waste material collection assembly 33 in sequence. Then, the first motion seat 334 drives the take-up roller 331 to move along its own axis (i.e., as shown). Figure 1(As shown, it moves outward along the paper surface) to the winding position, so that the spare material strip A2 passing through the waste collection assembly 33 enters the insertion slot k of the take-up roller 331. Then, the glue suction roller 421 is controlled to rotate to unwind the starting end A3 of the spare material strip A2 and the adhesive tape e, until the glue suction roller 421 separates from the starting end A3 of the spare material strip A2 and the adhesive tape e. At the same time, the second rotary drive 336 drives the take-up roller 331 to rotate and wind the spare material strip A2 onto the take-up roller 331, until both the starting end A3 of the spare material strip A2 and the adhesive tape e are wound onto the take-up roller 331. It should be noted that the spare material strip A2 and the adhesive tape e wound on the take-up roller 331 are the waste roll A4.

[0081] Furthermore, the waste collection assembly 33 also includes a pressing unit 332, which includes a connecting seat 3321, a pressing block 3322, and a first elastic member 3323. The connecting seat 3321 is mounted on the mounting plate 70 or the guide member 337 and is spaced apart from the take-up roller 331. The pressing block 3322 is movably connected to the side of the connecting seat 3321 facing the take-up roller 331. The first elastic member 3323 abuts between the connecting seat 3321 and the pressing block 3322, so that the pressing block 3322 presses the waste roll A4 wound on the take-up roller 331 under the elastic force provided by the first elastic member 3323. In this way, the spare material strip A2 (i.e., waste roll A4) wound on the take-up roller 331 is pressed tightly by the pressing block 3322 onto the take-up roller 331, preventing the waste roll A4 on the take-up roller 331 from loosening or even falling off. Alternatively, the first elastic element 3323 may be a compression spring.

[0082] Furthermore, the waste collection assembly 33 also includes a guide rod 3324, a mating plate 3326, and a limiting block 3325. A guide hole is provided on the connecting seat 3321, and the guide rod 3324 passes through the guide hole. The end of the guide rod 3324 facing the receiving roller 331 is fixedly connected to the pressure block 3322, and the end of the guide rod 3324 away from the receiving roller 331 is fixedly connected to the mating plate 3326. The limiting block 3325 is mounted on the connecting seat 3321, and under the elastic force provided by the first elastic element 3323, the mating plate 3326 tends to press against the limiting block 3325. Thus, when there is no waste roll A4 wound on the take-up roller 331, the mating plate 3326 abuts against the limiting block 3325 under the elastic force provided by the first elastic element 3323. This limiting block 3325 then limits the pressure block 3322, preventing it from directly pressing against the take-up roller 331 and thus avoiding bending deformation of the take-up roller 331 due to long-term stress. When there is waste roll A4 wound on the take-up roller 331, the pressure block 3322 presses against the waste roll A4 on the take-up roller 331. As the diameter of the waste roll A4 gradually increases, the pressure block 3322 gradually overcomes the elastic force of the first elastic element 3323 and moves towards the connecting seat 3321, thereby causing the mating plate 3326 to gradually move away from the limiting block 3325.

[0083] Furthermore, the position of the limiting block 3325 on the connecting seat 3321 is adjustable, thereby adjusting the gap between the pressure block 3322 and the take-up roller 331 by adjusting the position of the limiting block 3325, ensuring that there is a certain gap between the pressure block 3322 and the take-up roller 331 when there is no waste roll A4 being wound on the take-up roller 331, and pressing the pressure block 3322 against the waste roll A4 when there is waste roll A4 being wound on the take-up roller 331.

[0084] Optionally, the limiting block 3325 has a slotted hole 3327, and the waste collection assembly 33 also includes a locking bolt (not shown). This locking bolt passes through the slotted hole 3327 on the limiting block 3325 and is threadedly connected to the connecting seat 3321, thereby locking the limiting block 3325 onto the connecting seat 3321. Thus, the position of the limiting block 3325 is adjustable through the cooperation of the locking bolt and the slotted hole 3327.

[0085] In a specific embodiment, the roll changing device further includes a mounting plate 70, on which the take-up roller 331 is rotatably connected about its own axis and movably connected along its own axial direction. The waste collection assembly 33 also includes a moving drive 335, which is mounted between the first moving seat 334 and the mounting plate 70, for driving the first moving seat 334 to move relative to the mounting plate 70 along the axial direction of the take-up roller 331, thereby driving the take-up roller 331 to move between a stop position and a take-up position. Optionally, the moving drive 335 can be a cylinder.

[0086] Furthermore, the waste collection assembly 33 also includes a guide 337 and a bushing 338. The bushing 338 is mounted on the mounting plate 70 via the guide 337, allowing the bushing 338 to move axially relative to the mounting plate 70. A take-up roller 331 is fitted inside the bushing 338 and can rotate relative to the bushing 338 about its own axis. One end of the take-up roller 331 is driven by the second rotary drive 336, and the other end of the take-up roller 331 extends out of the bushing 338 and is used to wind up the spare strip A2 along its path. The insertion slot k is located at the portion of the take-up roller 331 that extends out of the bushing 338. Optionally, the guide 337 may be a linear bearing.

[0087] Please see also Figure 6 It should be noted that the unwinding mechanism 31 includes two unwinding units, and the tape receiving assembly 32 includes two tape receiving units. A tape receiving channel g is formed between the two tape receiving units. The two unwinding units are located on the same side of the two tape receiving units. Both unwinding units can load material rolls (i.e., working material rolls or spare material rolls A1) and unwind and output material tape (i.e., working material tape or spare material tape A2) to the tape receiving channel g. When the material roll loaded on one of the unwinding units is a working material roll, the material tape unwound and output by the unwinding unit to the tape receiving channel g is the working material tape. After passing through the tape receiving channel g, the working material tape continues to be conveyed downstream. The material roll loaded on the other unwinding unit is the spare material roll A1. The starting end A3 of the spare material roll A1 passes through the tape receiving channel g and the take-up roller 331 of the waste material receiving assembly 33 under the traction of the suction roller 421, and is then fixed on the take-up roller 331.

[0088] One unwinding unit and one tape-connecting unit located on the same side form one group, namely the first unwinding unit 31a and the first tape-connecting unit 32a. Another unwinding unit and another tape-connecting unit located on the same side form another group, namely the second unwinding unit 31b and the second tape-connecting unit 32b.

[0089] It should be noted that, in this article, "working roll" refers to the roll that is currently being unwound and outputs tape downstream, and the tape output from the working roll is the working tape. "Spare roll" refers to the roll that is not yet being unwound and output tape downstream; the tape on this spare roll is the spare tape. For example, when the roll on the first unwinding unit 31a is the working tape, the first unwinding unit 31a drives the working roll on it to rotate, thereby conveying the working tape downstream. After passing through the tape receiving channel g, the working tape continues to be conveyed downstream. At this time, the roll on the second unwinding unit 32a is the spare roll.

[0090] When the working roll on the first unwinding unit 31a is unwound, a roll change is required. After the roll change is completed, the spare roll on the second unwinding unit 31a is switched to the working roll and continues to unwind and output the working strip downstream. At this time, the material taking component 43 transfers the spare roll back to the first unwinding unit 31a and prepares for the next roll change.

[0091] To save space, the distance between the first unwinding unit 31a and the second unwinding unit 31b is small, as is the distance between the first tape-joining unit 32a and the second tape-joining unit 32b. Therefore, during the process of the suction roller 421 pulling the starting end A3 of the spare roll A1 on the first unwinding unit 31a through the tape-joining channel g and reaching the downstream of the take-up roller 331, the second unwinding unit 31b and the second tape-joining unit 32b are prone to interfering with the suction roller 421. Similarly, during the process of the suction roller 421 pulling the starting end A3 of the spare roll A1 on the second unwinding unit 31b through the tape-joining channel g and reaching the downstream of the take-up roller 331, the first unwinding unit 31a and the first tape-joining unit 32a are also prone to interfering with the suction roller 421.

[0092] To address the interference issue with the suction roller 421, in some embodiments, the first unwinding unit 31a is configured to be controllably movable along the axial direction of the take-up roller 331. A first attaching unit 32a is controllably connected to or disconnected from the first unwinding unit 31a. When the first attaching unit 32a is connected to the first unwinding unit 31a, it can move along the axial direction of the take-up roller 331 along with the first unwinding unit 31a. The second unwinding unit 31a is also configured to be controllably movable along the axial direction of the take-up roller 331. A second attaching unit 32b is controllably connected to or disconnected from the second unwinding unit 31b. When the second attaching unit 32b is connected to the second unwinding unit 31b, it can move along the axial direction of the take-up roller 331 along with the second unwinding unit 31b. It should be noted that the first unwinding unit 31a can be driven to move axially along the take-up roller 331 using linear drive components such as electric cylinders or lead screw modules, and this is not limited here. The second unwinding unit 31b can be driven to move axially along the take-up roller 331 using linear drive components such as electric cylinders or lead screw modules, and this is not limited here.

[0093] Furthermore, the first tape-attaching unit 32a and the second tape-attaching unit 32b can be selectively connected to the first moving seat 334. When the first tape-attaching unit 32a is connected to the first moving seat 334, the second tape-attaching unit 32b is separated from the first moving seat 334, thereby enabling the take-up roller 331 and the first tape-attaching unit 32a to move synchronously along the axial direction of the take-up roller 331. When the second tape-attaching unit 32b is connected to the first moving seat 334, the first tape-attaching unit 32a is separated from the first moving seat 334, thereby enabling the take-up roller 331 and the second tape-attaching unit 32b to move synchronously along the axial direction of the take-up roller 331.

[0094] Thus, when the roll on the first unwinding unit 31a is the spare roll A1, the first tape-connecting unit 32a is connected to the first unwinding unit 31a. At this time, the first unwinding unit 31a is moved axially along the take-up roller 331 (i.e., along...). Figure 1 The first unwinding unit 31a moves outward perpendicular to the paper surface, thereby also causing the first tape-joining unit 32a to move axially along the take-up roller 331. This causes the first unwinding unit 31a and the second unwinding unit 31b to be misaligned axially along the take-up roller 331, and the first tape-joining unit 32a and the second tape-joining unit 32b to also be misaligned axially along the take-up roller 331. This ensures that during the process of the glue suction roller 421 pulling the starting end A3 of the spare tape A2 on the first unwinding unit 31a through the tape-joining channel g and reaching the downstream of the take-up roller 331, there will be no interference with the second unwinding unit 31b, the second tape-joining unit 32b, and the take-up roller 331. After the glue suction roller 421 pulls the starting end A3 of the spare tape A2 to the downstream of the take-up roller 331, the first moving seat 334 moves axially along the take-up roller 331 (i.e., along the direction perpendicular to the paper surface). Figure 1 The unwinding unit 31a, the first tape receiving unit 32a, and the take-up roller 331 move together along the axial direction of the take-up roller 331 to the winding position, so that the take-up roller 331 can fix and wind up the spare tape A2. Finally, the first motion seat 334 is connected to the first tape receiving unit 32a, so that the first unwinding unit 31a, the first tape receiving unit 32a and the take-up roller 331 move together along the axial direction of the take-up roller 331 to reset (i.e., along the axial direction of the take-up roller 331). Figure 1 (Move inwards in a direction perpendicular to the paper surface) so that the two unwinding units, two splicing units, and waste collection assembly can work together to complete the splicing.

[0095] When the roll on the second unwinding unit 31b is the spare roll A1, the second tape-connecting unit 32b is connected to the second unwinding unit 31b. At this time, the second unwinding unit 31b is moved axially along the take-up roller 331 (i.e., along...). Figure 1The first unwinding unit 31b moves outward in a direction perpendicular to the paper surface to the feeding position, while simultaneously driving the second tape-connecting unit 32b to move along the axial direction of the take-up roller 331. This causes the second unwinding unit 31b and the first unwinding unit 31a to be misaligned in the axial direction of the take-up roller 331, and the second tape-connecting unit 32b and the first tape-connecting unit 32a to also be misaligned in the axial direction of the take-up roller 331. This ensures that during the process of the glue suction roller 421 pulling the starting end A3 of the spare tape A2 on the second unwinding unit 31b through the tape-connecting channel g and reaching the downstream of the take-up roller 331, there will be no interference with the first unwinding unit 31a, the first tape-connecting unit 32a, and the take-up roller 331. After the suction roller 421 pulls the starting end A3 of the spare material strip A2 downstream of the take-up roller 331, the first moving seat 334 moves axially along the take-up roller 331, thereby moving the take-up roller 331 to the winding position so that the take-up roller 331 can fix and wind up the spare material strip A2. Finally, the first moving seat 334 is connected to the second tape receiving unit 32b, so that the second unwinding unit 31b, the second tape receiving unit 32b and the take-up roller 331 move together axially along the take-up roller 331 to reset (i.e., along the axial direction of the take-up roller 331). Figure 1 (Move inwards in a direction perpendicular to the paper surface) so that the two unwinding units, the two splicing units, and the waste collection assembly 33 can cooperate with each other to complete the splicing.

[0096] Specifically, the belt-connecting mechanism 30 further includes a first clutch assembly 34, which includes a clutch slide 342 and a clutch drive member 341. The clutch slide 342 is movably connected to a first motion seat 334. The clutch drive member 341 is mounted on the first motion seat 334, and its drive end is connected to the clutch slide 342. The clutch drive member 341 can drive the clutch slide 342 relative to the first motion seat 334 to a first position connected to the first belt-connecting unit 32a and a second position connected to the second belt-connecting unit 32b.

[0097] It should be noted that in some embodiments, the clutch slide 342 is provided with a mating groove or hole. When the clutch slide 342 moves to the first position, a portion of the first receiving unit 32a is inserted into the mating groove or hole, thereby connecting the first receiving unit 32a with the clutch slide 342, so that the first moving seat 334 can drive the first receiving unit 32a to move together along the axial direction of the take-up roller 331. When the clutch slide 342 moves to the second position, a portion of the second receiving unit 32b is inserted into the mating groove or hole, thereby connecting the second receiving unit 32b with the clutch slide 342, so that the first moving seat 334 can drive the second receiving unit 32b to move together along the axial direction of the take-up roller 331. Of course, in other embodiments, the clutch slide 342 and the first receiving unit 32a or the second receiving unit 32b can also be connected in other ways, such as clamping, which is not limited here.

[0098] Specifically, the tape-connecting mechanism 30 further includes a second clutch assembly (not shown) and a third clutch assembly 36. The second clutch assembly is disposed between the first unwinding unit 31a and the first tape-connecting unit 32a, and controls the connection or separation of the first unwinding unit 31a and the first tape-connecting unit 32a. The third clutch assembly 36 is disposed between the second unwinding unit 31b and the second tape-connecting unit 32b, and controls the connection or separation of the second unwinding unit 31b and the second tape-connecting unit 32b.

[0099] Furthermore, the second clutch assembly includes a first clamping portion and a first connecting portion. One of the first clamping portion and the first connecting portion is mounted on the first unwinding unit 31a, and the other is mounted on the first tape-attaching unit 32a. The first clamping portion can controllably clamp or release the first connecting portion. When the first clamping portion clamps the first connecting portion, the first tape-attaching unit 32a and the first unwinding unit 31a are connected as a whole through the first clamping portion and the first connecting portion, and can move synchronously along the axial direction of the take-up roller 331. When the first clamping portion releases the first connecting portion, the first tape-attaching unit 32a separates from the first unwinding unit 31a and cannot move together along the axial direction of the take-up roller 331. It should be noted that the first clamping portion can adopt a claw structure, as long as it can clamp or release the first connecting portion, and is not limited here.

[0100] Furthermore, the third clutch assembly 36 includes a second clamping portion 361 and a second connecting portion 362. One of the second clamping portion 361 and the second connecting portion 362 is mounted on the second unwinding unit 31b, and the other is mounted on the second tape-attaching unit 32b. The second clamping portion 361 can controllably clamp or release the second connecting portion 362. When the second clamping portion 361 clamps the second connecting portion 362, the second tape-attaching unit 32b and the second unwinding unit 31b are connected as a whole through the second clamping portion 361 and the second connecting portion 362, and can move synchronously along the axial direction of the take-up roller 331. When the second clamping portion 361 releases the second connecting portion 362, the second tape-attaching unit 32b separates from the second unwinding unit 31b and cannot move together along the axial direction of the take-up roller 331. It should be noted that the second clamping portion 361 can adopt a claw structure, as long as it can clamp or release the second connecting portion 362, and is not limited here.

[0101] It should be noted that the method of using the first unwinding unit 31a to drive the first tape-joining unit 32a to move the first tape-joining unit 32a along the axial direction of the take-up roller 331 is not limited to this. In other embodiments, a driving component may also be provided to drive the first tape-joining unit 32a to move along the axial direction of the take-up roller 331.

[0102] Similarly, the second tape-connecting unit 32b is not limited to being driven by the second unwinding unit 31a to move along the axial direction of the take-up roller 331. In other embodiments, a driving component may also be provided to drive the second tape-connecting unit 32b to move along the axial direction of the take-up roller 331.

[0103] It should also be noted that, since the spare material roll A1 may be on the first unwinding unit 31a or the second unwinding unit 31b, in order to avoid the spare material strip A2 interfering with the downstream conveying of the working material strip, in some embodiments, the waste material collection assembly 33 has two take-up rollers 331, namely the first take-up roller and the second take-up roller. The first take-up roller is located on the same side as the first unwinding unit 31a and the first tape-joining unit 32a, and the second take-up roller is located on the same side as the second unwinding unit 31b and the second tape-joining unit 32b. Thus, when the spare material roll A1 is located on the first unwinding unit 31a, the spare material strip A2 of the spare material roll A1 pulled out by the glue suction roller 421 passes through the first unwinding unit 31a and the first tape-joining unit 32a in sequence, and is wound onto the first take-up roller. When the spare roll A1 is located on the second unwinding unit 31b, the spare strip A2 of the spare roll A1 pulled out by the glue suction roller 421 passes through the second unwinding unit 31b and the second strip receiving unit 32b in sequence, and is wound onto the second take-up roller.

[0104] It should be noted that in some embodiments, the two receiving rollers 331 can be driven by two separate second rotary drive members 336, thereby enabling the two receiving rollers 331 to rotate around their respective axes. Of course, in other embodiments, a single second rotary drive member 336 can be used to synchronously drive the two receiving rollers 331. Specifically, the waste collection assembly 33 also includes a drive wheel L1, a driven wheel L2, and a transmission belt L3. The drive wheel L1 and driven wheel L2 are respectively mounted on the two receiving rollers 331, and the transmission belt L3 is sleeved between the drive wheel L1 and the driven wheel L2. The drive end of the second rotary drive member 336 is connected to one of the receiving rollers 331, so that when one of the receiving rollers 331 rotates under the drive of the second rotary drive member 336, it can drive the other receiving roller 331 to rotate synchronously via the drive wheel L1, the transmission belt L3, and the driven wheel L2. Thus, the two receiving rollers 331 share a single second rotary drive member 336, which helps reduce the cost of the device.

[0105] Please see Figures 6 to 8In some embodiments, the adhesive dispensing mechanism 42 includes a first mounting base 418, a first rotary drive member 422, and a first rotating seat 423. The first mounting base 418 is mounted on the drive end of the drive assembly 41, enabling the drive assembly 41 to drive the first mounting base 418 to move. The first rotary drive member 422 is mounted on the first mounting base 418, and the first rotating seat 423 is mounted on the drive end of the first rotary drive member 422, enabling the first rotary drive member 422 to drive the first rotating seat 423 to rotate. The adhesive suction roller 421 is mounted on the first rotating seat 423, thereby enabling the adhesive suction roller 421 to rotate together with the first rotating seat 423.

[0106] The aforementioned drive assembly 41 is used to drive the first mounting base 418 to move along the first direction X1 and the second direction X2, or along the first direction X1, the second direction X2 and the third direction X3. The first rotary drive member 422 is used to drive the first rotary seat 423 to rotate around the axis of the suction roller 421. The first direction X1, the second direction X2 and the third direction X3 intersect each other. Thus, by driving the first mounting base 418 to move along the first direction X1 and the second direction X2, or along the first direction X1, the second direction X2 and the third direction X3, the first mounting base 418 can accurately drive the suction roller 421 to pick up the tape e at the glue preparation mechanism 10, release the tape e onto the suction surface f at the tape receiving assembly 32, adhere the starting end A3 of the spare material roll A1 at the unwinding mechanism 31, and pull the spare material roll A2 sequentially through the tape receiving assembly 32 and the waste collection assembly 33. The first rotary drive 422 drives the suction roller 421 to rotate around its own axis (i.e., the suction roller 421 rotates along the first or second direction of rotation), thereby realizing the winding or releasing of tape e or spare tape A2.

[0107] Specifically Figure 1 In the illustrated embodiment, the first direction X1 is the left-right direction, the second direction X2 is the up-down direction, and the third direction X3 is the direction perpendicular to the paper surface. This third direction X3 is aligned with the axial direction of the glue suction roller 421. It should be noted that the alignment of the third direction X3 with the axial direction of the glue suction roller 421 means that the third direction X3 is approximately parallel to the axial direction of the glue suction roller 421.

[0108] Specifically, the adhesive-taking mechanism 42 further includes a first slide 424 and a second slide 425, both mounted on the first rotating seat 423. The adhesive-absorbing roller 421 includes a first adsorption half-roller 4211 mounted on the first slide 424 and a second adsorption half-roller 4213 mounted on the second slide 425. The surfaces of the first adsorption half-roller 4211 and the second adsorption half-roller 4213, which are facing away from each other, combine to form a roller surface for winding the adhesive tape e. The first slide 424 and the second slide 425 can controllably drive the first adsorption half-roller 4211 and the second adsorption half-roller 4213 to move closer to or further away from each other to clamp or release the starting end of the adhesive tape e. Thus, when it is necessary to pick up the adhesive tape e provided by the adhesive preparation mechanism 10, firstly, the first slide 424 and the second slide 425 drive the first adsorption half-roller 4211 and the second adsorption half-roller 4213 away from each other. The drive assembly 41 drives the adhesive-picking mechanism 42 to move to the adhesive preparation mechanism 10, so that the starting end of the tape e is inserted between the first adsorption half-roller 4211 and the second adsorption half-roller 4213. Then, the first slide block 424 and the second slide block 425 drive the first adsorption half-roller 4211 and the second adsorption half-roller 4213 to move closer to each other until the starting end of the tape e between them is clamped. Then, the first rotary drive member 422 drives the first adsorption half-roller 4211 and the second adsorption half-roller 4213 to rotate in the first rotation direction or the second rotation direction until a certain length of tape e is wound onto the first adsorption half-roller 4211 and the second adsorption half-roller 4213. Finally, the adhesive preparation mechanism 10 is controlled to cut the tape e, thereby realizing that the adhesive suction roller 421 picks up a certain length of tape e. It should be noted that in this embodiment, both the first slide 424 and the second slide 425 are movable. In other embodiments, either the first slide 424 or the second slide 425 may be movable while the other remains stationary, as long as it enables the first adsorption half-roller 4211 and the second adsorption half-roller 4213 to clamp or release the starting end of the tape e. No limitation is made here. For ease of understanding, this article uses the example of both the first slide 424 and the second slide 425 being movable for illustration.

[0109] Furthermore, the surfaces of the first adsorption half-roller 4211 and the second adsorption half-roller 4213 that are opposite to each other are both adsorption surfaces h. These adsorption surfaces h are used to adsorb the tape e wound on them, preventing the tape e wound on the first adsorption half-roller 4211 and the second adsorption half-roller 4213 from becoming loose or even falling off. Optionally, the adsorption surface h can be used to adsorb and fix the tape e using vacuum adsorption. Specifically, the adsorption surface h has multiple adsorption holes, each of which is connected to an external negative pressure source. This allows the external negative pressure source to create negative pressure at each adsorption hole, thereby using this negative pressure to adsorb and fix the tape e onto the adsorption surface h.

[0110] Furthermore, the adhesive-taking mechanism 42 also includes a first clamping drive 426 and a second clamping drive 427, both mounted on the first rotating seat 423. The driving end of the first clamping drive 426 is connected to the first slide 424, enabling the first clamping drive 426 to drive the first slide 424 closer to or away from the second slide 425, thereby causing the first slide 424 to move the first adsorption half-roller 4211 closer to or away from the second adsorption half-roller 4213. The driving end of the second clamping drive 427 is connected to the second slide 425, enabling the second clamping drive 427 to drive the second slide 425 closer to or away from the first slide 424, thereby causing the second slide 425 to move the second adsorption half-roller 4213 closer to or away from the first adsorption half-roller 4211. Optionally, both the first clamping drive 426 and the second clamping drive 427 can be cylinders.

[0111] Thus, when the adhesive roller 421 needs to clamp the tape e at the adhesive preparation mechanism 10, the first clamping drive member 426 drives the first adsorption half roller 4211 to move closer to the second adsorption half roller 4213. At the same time, the second clamping drive member 427 also drives the second adsorption half roller 4213 to move closer to the first adsorption half roller 4211, until the first adsorption half roller 4211 and the second adsorption half roller 4213 jointly clamp the tape e between them.

[0112] When the first adsorption half-roller 4211 of the adhesive suction roller 421 abuts against the adhesive suction surface f of the tape receiving assembly 32, and it is necessary to release the tape e, the second clamping drive member 427 drives the second adsorption half-roller 4213 away from the first adsorption half-roller 4211, thereby releasing the tape e. At this time, the first clamping drive member 426 does not drive the first adsorption half-roller 4211 to move, thereby avoiding excessive pressure between the first adsorption half-roller 4211 and the adhesive suction surface f, which could damage the tape e.

[0113] When the second adsorption half-roller 4213 of the adhesive suction roller 421 abuts against the adhesive suction surface f of the tape receiving assembly 32, and it is necessary to release the tape e, the first clamping drive member 426 drives the first adsorption half-roller 4211 away from the second adsorption half-roller 4213, thereby releasing the tape e. At this time, the second clamping drive member 427 does not drive the second adsorption half-roller 4213 to move, thereby avoiding excessive pressure between the second adsorption half-roller 4213 and the adhesive suction surface f, which could damage the tape e.

[0114] Furthermore, a first slide rail is provided on the first rotating seat 423, and both the first slide block 424 and the second slide block 425 are disposed on the first slide rail. This allows the first slide block 424 to move along the first slide rail under the driving action of the first clamping drive member 426, while the second slide block 425 can also move along the first slide rail under the driving action of the second clamping drive member 427, thereby causing the first adsorption half-roller 4211 and the second adsorption half-roller 4213 to move closer to or further away from each other, respectively. In this way, the movement of the first slide block 424 and the second slide block 425 is guided by the first slide rail, ensuring that the clamping and releasing actions of the first adsorption half-roller 4211 and the second adsorption half-roller 4213 are more accurate and reliable.

[0115] In some embodiments, the drive assembly 41 includes a drive unit 410, a third transfer seat 416, and an elastic buffer 419. The third transfer seat 416 is mounted on the drive end of the drive unit 410, and a first mounting seat 418 is movably connected to the third transfer seat 416, thereby enabling the drive unit 410 to drive the first mounting seat 418 to move via the third transfer seat 416, which in turn causes the first mounting seat 418 to drive the suction roller 421 to move together. The two ends of the elastic buffer 419 are respectively connected to the first mounting seat 418 and the third transfer seat 416, so that the elastic buffer 419 can buffer the impact on the suction roller 421. Thus, when the first mounting base 418 drives the suction roller 421 to press against the suction surface f of the tape receiving assembly 32, the first mounting base 418 can float relative to the third transfer base 416 under the action of the pressure, thereby further compressing the elastic buffer 419, thereby buffering the impact force between the suction roller 421 and the suction surface f, and avoiding hard impact between the suction roller 421 and the suction surface f that would damage the tape e.

[0116] Similarly, when the first mounting base 418 drives the suction roller 421 to press against the spare material roll A1, under the action of the pressure, the first mounting base 418 can float relative to the third transfer base 416 and further compress the elastic buffer 419, thereby buffering the impact force between the suction roller 421 and the spare material roll A1, and avoiding hard impact between the suction roller 421 and the spare material roll A1 that could damage the tape e or the spare material roll A1.

[0117] It should be noted that the elastic buffer 419 can be an elastic device that can generate buffering force, such as a cylinder or a spring. In the embodiment where the elastic buffer 419 uses a cylinder, since the buffering force output by the cylinder can remain constant and does not increase with the increase of compression, it can ensure that the pressure between the glue suction roller 421 and the glue suction surface f or the spare material roll A1 remains constant, thereby avoiding excessive or insufficient pressure.

[0118] Specifically, in the embodiments, the driving unit 410 includes a translation driving member 411 (see...). Figure 1The system comprises a first driving member 412, a first transfer seat 413, a second driving member 414, a second transfer seat 415, and a third driving member 417. The first driving member 412 is mounted on the driving end of the translation driving member 411, enabling the translation driving member 411 to drive the first driving member 412 to move along a first direction X1. The first transfer seat 413 is mounted on the driving end of the first driving member 412, enabling the first driving member 412 to drive the first transfer seat 413 to move along a third direction X3. The second driving member 414 is mounted on the first transfer seat 413, enabling the second 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 second driving member 414, enabling the second 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 third drive member 417 is mounted on the second transfer seat 415, enabling the third drive member 417 to move together with the second transfer seat 415. The third transfer seat 416 is movably connected to the second transfer seat 415 along a third direction X3 and is connected to the drive end of the third drive member 417, enabling the third drive member 417 to drive the third transfer seat 416 to move relative to the second transfer seat 415 along the third direction X3. The aforementioned first mounting seat 418 is movably connected to the third transfer seat 416 along a second direction X2, enabling the first mounting seat 418 to move together with the third transfer seat 416, thereby driving the adhesive suction roller 421 to move together with the third transfer seat 416.

[0119] Thus, the translational drive 411 drives the suction roller 421 to move along the first direction X1, the first drive 412 drives the suction roller 421 to move along the third direction X3, the second drive 414 drives the suction roller 421 to move along the second direction X2, the third drive 417 drives the suction roller 421 to move along the third direction X3, and the first rotational drive 422 drives the suction roller 421 to rotate around its own axis. This allows the suction roller 421 to accurately complete the transfer of tape e, the use of tape e to pick up the starting end A3 of the spare material roll A1, and the traction of the spare material roll A2 through the tape receiving assembly 32 and the waste collection assembly 33. It should be noted that the translational drive 411, the first drive 412, the second drive 414, and the third drive 417 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 suction roller 421; no limitation is made here.

[0120] 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.

[0121] Furthermore, a third slide rail is provided on the second transfer seat 415, which extends longitudinally along the third direction X3. The third transfer seat 416 is slidably disposed on the third slide rail, thereby guiding the movement of the third transfer seat 416 relative to the second transfer seat 415 along the third direction X3.

[0122] Furthermore, a fourth slide rail is provided on the third transfer seat 416, which extends longitudinally along the second direction X2. The first mounting seat 418 is slidably mounted on the fourth slide rail, thereby guiding the movement of the first mounting seat 418 relative to the third transfer seat 416 along the second direction X2 using the fourth slide rail.

[0123] Please see again Figure 2 and Figure 3 In the embodiments of this application, the adhesive preparation mechanism 10 includes a mounting base 16 and a tape unwinding assembly 11 and a cutting assembly 12, both mounted on the mounting base 16. The tape unwinding assembly 11 is used to unwind and output tape e to the cutting assembly 12. The driving assembly 41 can drive the adhesive picking mechanism 42 to move downstream of the cutting assembly 12, so that the adhesive picking mechanism 42's suction roller 421 clamps and fixes the starting end of the tape e. After the suction roller 421 clamps and fixes the starting end of the tape e, the suction roller 421 rotates around its own axis, thereby winding the tape e onto the suction roller 421. After a certain length of tape e is wound onto the suction roller 421, the cutting assembly 12 cuts the passing tape e, thereby enabling the suction roller 421 to pick up a certain length of tape e.

[0124] Specifically, in this embodiment, the adhesive preparation mechanism 10 further includes a first clamping assembly 13 and a second clamping assembly 14, both mounted on the mounting base plate 16. The first clamping assembly 13 is located upstream of the cutting assembly 12 and is used to clamp or release the passing adhesive tape e. The second clamping assembly 14 is located downstream of the cutting assembly 12 and is used to clamp or release the passing adhesive tape e. Thus, during the process of the adhesive suction roller 421 clamping and fixing the starting end of the adhesive tape e and winding the adhesive tape e, both the first clamping assembly 13 and the second clamping assembly 14 remain in a state of releasing the adhesive tape e, so that the adhesive tape e can be conveyed downstream and wound onto the adhesive suction roller 421 under the traction of the adhesive suction roller 421. After the adhesive suction roller 421 has wound a certain length of adhesive tape e, the adhesive suction roller 421 stops rotating, and the first clamping assembly 13 and the second clamping assembly 14 each clamp the passing adhesive tape e. Then, the cutting component 12 cuts the passing tape e, so that the suction roller 421 can carry the tape e wound on it together to the tape receiving component 32 or the unwinding mechanism 31 to move the spare roll A1.

[0125] Specifically, the cutting assembly 12 includes a cutting drive (not shown) and a cutter (not shown). The cutting drive is mounted on the mounting base plate 16, and the cutter is mounted on the drive end of the cutting drive, enabling the cutting drive to drive the cutter to perform a cutting action, thereby cutting the passing tape e. Optionally, the cutting drive can be a cylinder.

[0126] Specifically, the first clamping assembly 13 includes a first adhesive clamping drive (not shown) and two first adhesive clamping blocks (not shown). The first adhesive clamping drive is mounted on the mounting base plate 16, and the two first adhesive clamping blocks are respectively mounted on the two drive ends of the first adhesive clamping drive, with a first adhesive clamping channel formed between the two first adhesive clamping blocks for the tape e to pass through. The first adhesive clamping drive is used to drive the two first adhesive clamping blocks to clamp or release the tape e between them. Optionally, the first adhesive clamping drive can be a gripper cylinder.

[0127] Specifically, the second clamping assembly 14 includes a second adhesive clamping drive (not shown) and two second adhesive clamping blocks (not shown). The second adhesive clamping drive is mounted on the mounting base plate 16, and the two second adhesive clamping blocks are respectively mounted on the two drive ends of the second adhesive clamping drive, with a second adhesive clamping channel formed between the two second adhesive clamping blocks for the tape e to pass through. The second adhesive clamping drive is used to drive the two second adhesive clamping blocks to clamp or release the tape e between them. Optionally, the second adhesive clamping drive can be a gripper cylinder.

[0128] Furthermore, the adhesive preparation mechanism 10 also includes a buffer assembly 15 mounted on the mounting base plate 16. This buffer assembly 15 is located between the cutting assembly 12 and the tape unwinding assembly 11, and is used to buffer the passing tape e. Thus, by buffering the tape e with the buffer assembly 15, during the process of the suction roller 421 winding the tape e, the buffer assembly 15 releases the tape e (i.e., the amount of buffered tape e decreases). The tape e released by the buffer assembly 15 is ultimately wound onto the suction roller 421, thereby preventing the suction roller 421 from directly pulling the tape e from the tape unwinding assembly 11 when winding the tape e, and thus preventing the tape e from being torn due to excessive tension.

[0129] Specifically, the buffer assembly 15 includes a fixed guide roller 151 and a movable guide roller 152 disposed on the mounting substrate 16. The fixed guide roller 151 is fixed in position relative to the mounting substrate 16, while the movable guide roller 152 can move closer to or away from the fixed guide roller 151 under the action of an external force. Thus, when the suction roller 421 winds the tape e, the tape e drives the movable guide roller 152 to move closer to the fixed guide roller 151, thereby reducing the length of the tape e buffered between the movable guide roller 152 and the fixed guide roller 151. When the suction roller 421 stops winding the tape e, the movable guide roller 152 moves away from the fixed guide roller 151 and resets, thereby increasing the length of the tape e buffered between the movable guide roller 152 and the fixed guide roller 151.

[0130] Furthermore, the buffer assembly 15 also includes a movable block 153 and a buffer drive 154. The movable block 153 is movably connected to the mounting base 16, and the movable roller 152 is mounted on the movable block 153, allowing the movable roller 152 to move relative to the mounting base 16 along with the movable block 153, thereby moving closer to or away from the fixed roller 151. The buffer drive 154 is mounted on the mounting base 16 and provides a driving force that causes the movable block 152 to move the movable roller 152 away from the fixed roller 151. Thus, when the suction roller 421 winds the tape e, the tape e drives the movable block 153 and the movable roller 152 closer to the fixed roller 151, thereby reducing the length of the tape e buffered between the movable roller 152 and the fixed roller 151. When the suction roller 421 stops winding the tape e, the movable block 153, driven by the buffer drive 154, moves the movable guide roller 152 away from the fixed guide roller 151 and resets, thereby increasing the length of the tape e buffered between the movable guide roller 152 and the fixed guide roller 151. Optionally, the buffer drive 154 can be a cylinder.

[0131] Furthermore, a fifth slide rail (not shown) is provided on the mounting base plate 16, and the movable block 153 is slidably disposed on the fifth slide rail, thereby using the fifth slide rail to guide the movement of the movable block 153 relative to the mounting base plate 16.

[0132] Please see Figures 15 to 17 and Figure 20 In the embodiments of this application, the material preparation assembly 20 includes a support base 21, a material storage shaft 22, and a material pushing assembly 23. The axial ends of the material storage shaft 22 are a mounting end a1 and an inlet / outlet end a2, respectively. The mounting end a1 of the material storage shaft 22 is mounted on the support base 21, and the material storage shaft 22 is used to mount at least one spare material roll A1 axially. The material taking assembly 43 has a material taking shaft 431 (see...) Figure 18The drive assembly 41 drives the picking assembly 43 to move to the preparation assembly 20, so that the picking shaft 431 of the picking assembly 43 is axially aligned with the inlet / outlet end a2 of the storage shaft 22 of the preparation assembly 20. The push assembly 23 is mounted on the support base 21 and is used to push the spare material rolls A1 on the storage shaft 22 to move past the inlet / outlet end a2 of the storage shaft 22 to the picking shaft 431. Thus, in actual use, firstly, the drive assembly 41 drives the picking assembly 43 to move to the preparation assembly 20, so that the picking shaft 431 of the picking assembly 43 is axially aligned with the inlet / outlet end a2 of the storage shaft 22 of the preparation assembly 20. Then, the push assembly 23 pushes each spare material roll A1 on the storage shaft 22 toward the inlet / outlet end a2 of the storage shaft 22 until the spare material roll A1 closest to the inlet / outlet end a2 of the storage shaft 22 passes the inlet / outlet end a2 and moves to the picking shaft 431. Then, the drive assembly 41 drives the take-up assembly 43 to move toward the unwinding mechanism 31 to transfer the spare roll A1 on the take-up shaft 431 to the unwinding mechanism 31.

[0133] In some embodiments, the feeding assembly 23 includes a feeding drive 231, a telescopic unit 233, and a feeding block 232. The feeding drive 231 is mounted on the support base 21, and the feeding block 232 is disposed on the storage shaft 22. The telescopic unit 233 is connected between the feeding drive 231 and the feeding block 232. The feeding drive 231 is used to drive the telescopic unit 233 to extend and retract, thereby causing the feeding block 232 to move along the storage shaft 22, thereby pushing each spare material roll A1 on the storage shaft 22 toward the inlet / outlet end a2 of the storage shaft 22.

[0134] Further, the telescopic unit 233 includes a first movable seat 2331, a connecting rod telescopic frame 2336, a second movable seat 2333, and a second mounting seat 2335. The first movable seat 2331 is mounted on the drive end of the pusher drive member 231, which drives the first movable seat 2331 to move along a first direction X1. The second movable seat 2333 is movably connected to the second mounting seat 2335, and the pusher block 232 is mounted on the second movable seat 2333. The connecting rod telescopic frame 2336 is hinged between the first movable seat 2331 and the second movable seat 2333, and is used to convert the movement of the first movable seat 2331 along the first direction X1 into the movement of the pusher block 232 along a third direction X3. This third direction X3 is aligned with the axial direction of the storage shaft 22. Thus, when material needs to be pushed, the pushing drive 231 drives the first moving seat 2331 to move along the first direction X1, thereby causing the connecting rod telescopic frame 2336 to extend along the axial direction of the storage shaft 22, thereby driving the second mounting seat 2335 and the pushing block 232 to move along the axial direction of the storage shaft 22, thereby realizing the movement of each spare material roll A1 on the storage shaft 22 towards the inlet / outlet end a2 of the storage shaft 22.

[0135] It should be noted that using the telescopic linkage 2336 for transmission is beneficial to convert the smaller stroke output by the pusher drive 231 into the larger stroke of the pusher block 232. On the one hand, it helps to reduce the size of the pusher drive 231 and reduce equipment costs; on the other hand, it makes the structure more compact, reduces the space required, especially the space occupied in the axial direction of the storage shaft 22, and improves space utilization.

[0136] Specifically, the linkage telescopic frame 2336 includes a plurality of first links b1 arranged parallel to each other and spaced apart, and a plurality of second links b2 arranged parallel to each other and spaced apart. Each first link b1 and each second link b2 are arranged in a one-to-one correspondence. Each first link b1 and its corresponding second link b2 are hinged at the intersection, and the end of each first link b1 is hinged to the end of the adjacent second link b2.

[0137] The telescopic unit 233 also includes a first fixed seat 2332 and a second fixed seat 2334. The first fixed seat 2332 is mounted on the support seat 21 and is spaced apart from the first movable seat 2331 along the first direction X1. The second fixed seat 2334 is mounted on the second mounting seat 2335 and is spaced apart from the second movable seat 2333 along the first direction X1. At the end of the linkage telescopic frame 2336 near the first movable seat 2331: one of the ends of the first connecting rod b1 and the second connecting rod b2 is hinged to the first movable seat 2331, and the other is hinged to the first fixed seat 2332. At the end of the linkage telescopic frame 2336 near the second movable seat 2333: one of the ends of the first connecting rod b1 and the second connecting rod b2 is hinged to the second movable seat 2333, and the other is hinged to the second fixed seat 2334.

[0138] Thus, when the pusher drive 231 drives the first movable seat 2331 to move closer to the first fixed seat 2332, it can gradually reduce the intersection angle θ of each set of intersecting first connecting rods b1 and second connecting rods b2, causing the connecting rod telescopic frame 2336 to extend axially along the storage shaft 22, thereby driving the second mounting seat 2335 and the pusher block 232 to move axially along the storage shaft 22 toward the inlet / outlet end a2. During the extension process, the connecting rod telescopic frame 2336 drives the second movable seat 2333 to gradually move closer to the second fixed seat 2334.

[0139] When the pusher drive 231 drives the first movable seat 2331 to move away from the first fixed seat 2332, it can gradually increase the intersection angle θ of each set of intersecting first connecting rods b1 and second connecting rods b2, causing the connecting rod telescopic frame 2336 to retract axially along the storage shaft 22, thereby driving the second mounting seat 2335 and the pusher block 232 to move axially along the storage shaft 22 towards the mounting end a1. During the retraction process, the connecting rod telescopic frame 2336 drives the second movable seat 2333 to gradually move away from the second fixed seat 2334.

[0140] In a specific embodiment, the pushing assembly 23 further includes a first support roller 234 rotatably connected to the pushing block 232. The pushing block 232 is supported on the storage shaft 22 by the first support roller 234, so that when the connecting rod telescopic frame 2336 drives the pushing block 232 to move axially along the storage shaft 22, the first support roller 234 rolls on the storage shaft 22, which helps to reduce the thrust required to push each spare material roll A1 to move axially along the storage shaft 22 and reduces the difficulty of pushing.

[0141] It should be noted that the number of first support rollers 234 can be one, two, or more. When there is only one first support roller 234, the pusher block 232 is supported on the storage shaft 22 by that single first support roller 234. When there are multiple first support rollers 234, the pusher block 232 is supported on the storage shaft 22 by all the first support rollers 234. The number of first support rollers 234 can be set according to the size of the storage shaft 22, as long as it can reduce the frictional force generated by the axial movement of the pusher block 232 along the storage shaft 22, and is not limited here.

[0142] Specifically, in this embodiment, the material preparation assembly 20 further includes a plurality of second support rollers (not shown) that are rotatably connected to the storage shaft 22. These second support rollers are spaced apart along the axial direction of the storage shaft 22, and the spare material rolls A1 are supported on the storage shaft 22 by their corresponding second support rollers. Thus, when the pusher block 232 pushes each spare material roll A1, each spare material roll A1 moves axially along the storage shaft 22 under the rolling action of its corresponding second support roller, greatly reducing the thrust required to move each spare material roll A1 axially along the storage shaft 22, and further reducing the difficulty of pushing the material.

[0143] Please see Figure 18 , Figure 19 and Figure 21In the embodiments of this application, the unwinding mechanism 31 has an unwinding shaft 311 for loading a spare roll A1. The material taking assembly 43 includes the aforementioned material taking shaft 431, a support 432, and a feeding unit 435. The support 432 is mounted on the driving end of the translation drive 411, enabling the translation drive 411 to drive the support 432 to move along the first direction X1. The material taking shaft 431 and the feeding unit 435 are both mounted on the support 432, enabling the material taking shaft 431 and the feeding unit 435 to move together with the support 432. Under the driving action of the translation drive 411, the support 432 can drive the material taking shaft 431 to move along the first direction X1 to axially align with the storage shaft 22, so that the pushing assembly 23 can push the spare roll A1 on the storage shaft 22 onto the material taking shaft 431. Driven by the translation drive 411, the support 432 can also move the take-up shaft 431 to axially align with the unwinding shaft 311. At this time, the feeding unit 435 can controllably push the spare roll A1 on the take-up shaft 431 axially onto the unwinding shaft 311, thereby realizing the transfer of the spare roll A1 from the storage shaft 22 to the unwinding shaft 311.

[0144] In a specific embodiment, the material handling assembly 43 further includes a third mounting base 433 and a fourth driving member 434. The third mounting base 433 is movably connected to the support base 432 along a third direction X3. The fourth driving member 434 is mounted on the support base 432, and the driving end of the fourth driving member 434 is connected to the third mounting base 433, enabling the fourth driving member 434 to drive the third mounting base 433 to move relative to the support base 432 along a third direction X3. A material handling shaft 431 is mounted on the third mounting base 433, enabling the material handling shaft 431 to move together with the third mounting base 433. The axial direction of the material handling shaft 431 is aligned with the third direction X3.

[0145] The translation drive 411 of the drive assembly 41 drives the carrier 432 to move along the first direction X1, thereby causing the take-up shaft 431 to move along the first direction X1, so that the take-up shaft 431 moves along the first direction X1 to be opposite to the storage shaft 22 or the unwinding shaft 311 in the third direction X3. The fourth drive 434 drives the third mounting base 433 to move along the third direction X3, thereby causing the take-up shaft 431 to move along the third direction X3, so that the take-up shaft 431 moves along the third direction X3 to be axially connected to or separated from the storage shaft 22 or the unwinding shaft 311.

[0146] It should be noted that the material roll (i.e., the working material roll or the spare material roll A1) includes a drum A5 and the strip wound on the drum A5. After the spare material roll A1 on the unwinding shaft 311 of the unwinding mechanism 31 is switched to the working material roll, the unwinding shaft 311 of the unwinding mechanism 31 drives the working material roll to rotate and unwind the working strip downstream. When the working material roll on the unwinding shaft 311 is unwound, the tape receiving assembly 32 cuts off the passing working strip and spare strip A2. The unwinding shaft 311 of the unwinding mechanism 31 drives the drum A5 on it to rotate in the opposite direction until the upstream cut end of the working strip is wound onto the drum A5. At this time, the drum A5 on the unwinding shaft 311 needs to be unloaded from the unwinding shaft 311 and transferred to a designated position.

[0147] To unload the drum A5 from the unwinding shaft 311, in some embodiments, the translation drive 411 of the drive assembly 41 can drive the carrier 432 to move along a first direction X1 to the unwinding shaft 311, so that the take-up shaft 431 and the unwinding shaft 311 are opposite each other in a third direction X3. The fourth drive 434 can drive the third mounting base 433 to move along a third direction X3, thereby causing the take-up shaft 431 to axially engage with the unwinding shaft 311. The feeding unit 435 can controllably clamp the drum A5 on the unwinding shaft 311 and move the drum A5 axially to the take-up shaft 431, thereby realizing the transfer of the drum A5 from the unwinding shaft 311 to the take-up shaft 431.

[0148] It should be noted that in this embodiment, the feeding unit 435 pushes the spare material roll A1 on the take-up shaft 431 along the third direction X3 to the unwind shaft 311. The feeding unit 435 clamps the material cylinder A5 on the unwind shaft 311 and moves the material cylinder A5 along the third direction X3 to the take-up shaft 431. Compared with the scheme of pushing the material cylinder A5 on the unwind shaft 311 to the take-up shaft 431, the method of using the feeding unit 435 to clamp the material cylinder A5 in this embodiment can reduce the stroke of the feeding unit 435, thereby saving space, especially the space in the third direction X3.

[0149] It should be noted that the material cylinder A5 on the unwinding shaft 311 is not limited to being transferred to the take-up shaft 431 by the feeding unit 435. In other embodiments, after the feeding unit 435 clamps the material cylinder A5 on the unwinding shaft 311 and drives the material cylinder A5 axially away from the unwinding shaft 311, the material cylinder A5 is not sleeved on the take-up shaft 431, but is clamped and fixed by the feeding unit 435. For ease of understanding, this article uses the implementation method of transferring the material cylinder A5 on the unwinding shaft 311 to the take-up shaft 431 by the feeding unit 435 as an example for explanation.

[0150] Specifically, in this embodiment, the feeding unit 435 includes a fifth driving member 4351, a fourth mounting base 4352, and a clamping part 4353. The fifth driving member 4351 is mounted on the support base 432, allowing the fifth driving member 4351 to move together with the support base 432. The fourth mounting base 4352 is mounted on the driving end of the fifth driving member 4351, and the fifth driving member 4351 drives the fourth mounting base 4352 to move along a third direction X3. The clamping part 4353 is mounted on the fourth mounting base 4352, allowing the clamping part 4353 to move together with the fourth mounting base 4352. It should be noted that the fifth driving member 4351 can be a linear drive module such as an electric cylinder or a pneumatic cylinder, and is not limited here.

[0151] Thus, when it is necessary to push the spare roll A1 on the take-up shaft 431 onto the unwinding shaft 311, the clamping part 4353 is located at the end of the spare roll A1 away from the unwinding shaft 311. The fifth drive member 4351 drives the fourth mounting base 4352 to move along the third direction X3, thereby driving the clamping part 4353 to push the spare roll A1 on the take-up shaft 431 toward the unwinding shaft 311 along the third direction X3 until the spare roll A1 is pushed onto the unwinding shaft 311.

[0152] When it is necessary to push the drum A5 on the unwinding shaft 311 onto the take-up shaft 431, the fifth drive member 4351 drives the fourth mounting base 4352 to move towards the unwinding shaft 311 along the third direction X3, thereby causing the clamping part 4353 to move along the third direction X3 to the drum A5 on the unwinding shaft 311. Then, the clamping part 4353 clamps the drum A5 on the unwinding shaft 311. Then, the fifth drive member 4351 drives the fourth mounting base 4352 to move towards the take-up shaft 431 along the third direction X3, thereby causing the clamping part 4353 to move along the third direction X3 to the take-up shaft 431. Since the clamping part 4353 clamps the drum A5, the drum A5 also moves from the unwinding shaft 311 onto the take-up shaft 431 along with the clamping part 4353.

[0153] Specifically, the clamping part 4353 includes a gripper drive c1 and two grippers c2. The gripper drive c1 is mounted on the fourth mounting base 4352, allowing it to move along with the fourth mounting base 4352. The two grippers c2 are respectively mounted on the two driving ends of the gripper drive c1, and a clamping space is formed between the two grippers c2 for the material take-up shaft 431 or the unwinding shaft 311 to pass through. The gripper drive c1 is used to drive the two grippers c2 to clamp or release the material cylinder A5 on the unwinding shaft 311. Optionally, the gripper drive c1 can be a gripper cylinder.

[0154] Thus, when it is necessary to push the spare roll A1 on the take-up shaft 431 onto the unwinding shaft 311, the two grippers c2 are located at the end of the spare roll A1 away from the unwinding shaft 311, and the gripper drive member c1 drives the two grippers c2 to move closer to each other, so that the two grippers c2 can abut against the end of the spare roll A1. Then, the fifth drive member 4351 drives the fourth mounting base 4352 to move closer to the unwinding shaft 311 along the third direction X3, thereby driving the two grippers c2 to push the spare roll A1 on the take-up shaft 431 toward the unwinding shaft 311 along the third direction X3 until the spare roll A1 is pushed onto the unwinding shaft 311.

[0155] When the drum A5 on the unwinding shaft 311 needs to be pushed onto the take-up shaft 431, the gripper drive c1 drives the two grippers c2 to move away from each other, making the clamping space between the two grippers c2 wide enough for the drum A5 on the unwinding shaft 311 to enter. Then, the fifth drive 4351 drives the fourth mounting base 4352 to move closer to the unwinding shaft 311 along the third direction X3, thereby moving the two grippers c2 along the third direction X3 to the drum A5 on the unwinding shaft 311. At this time, the drum A5 on the unwinding shaft 311 is located between the two grippers c2. Then, the gripper drive c1 controls the two grippers c2 to move closer to each other until the drum A5 on the unwinding shaft 311 is clamped. Then, the fifth drive unit 4351 drives the fourth mounting base 4352 to move along the third direction X3 towards the take-up shaft 431, thereby driving the two grippers c2 to move along the third direction X3 to the take-up shaft 431. Since the two grippers c2 clamp the material cylinder A5, the material cylinder A5 also moves from the unwinding shaft 311 to the take-up shaft 431 along with the two grippers c2.

[0156] Please see Figure 1 , Figure 23 and Figure 24In an embodiment of this application, the transfer mechanism 40 further includes an unloading assembly 60, which includes a guide 61 and a storage container 62. The two longitudinal ends of the guide 61 are a feeding end d1 and a connecting end d2, respectively. The guide 61 is connected to the storage container 62 through the connecting end d2. Under the driving action of the translation drive 411 of the drive assembly 41, the support seat 432 can drive the picking shaft 431 to move to the feeding end d1. The feeding unit 435 can controllably push the cylinder A5 on the picking shaft 431 axially away from the picking shaft 431 and fall into the feeding end d1 of the guide 61. The guide 61 is configured to guide the cylinder A5 at the feeding end d1 to roll toward the connecting end d2 and reach the storage container 62. Thus, after the material cylinder A5 is transferred from the unwinding shaft 311 to the take-up shaft 431, firstly, the translation drive 411 drives the carrier 432 to move along the first direction X1 towards the guide 61 until the take-up shaft 431 reaches above the feed end d1 of the guide 61. Then, the fifth drive 4351 drives the fourth mounting base 4352 to move along the third direction X3, thereby causing the two grippers c2 to push the material cylinder A5 away from the take-up shaft 431 along the third direction X3, so that the material cylinder A5 falls into the feed end d1 of the guide 61. The material cylinder A5, which has fallen into the feed end d1 of the guide 61, rolls along the guide 61 towards the connecting end d2 until the material cylinder A5 reaches the storage unit 62 for storage.

[0157] Specifically, in this embodiment, the guide member 61 has a guide groove 612 extending longitudinally from the feed end d1 to the connecting end d2. This guide groove 612 is used to receive the material cylinder A5 and guide it to roll from the feed end d1 to the connecting end d2. Thus, by using the guide groove 612 to receive and guide the material cylinder A5 into the storage member 62, the risk of the material cylinder A5 falling off the guide member 61 is effectively reduced.

[0158] Furthermore, the storage component 62 has a storage trough 622 for receiving the material cylinder A5. The unloading assembly 60 also includes a seventh drive member 641 and a pusher block 642. The pusher block 642 is mounted on the drive end of the seventh drive member 641 and is located at the end of the storage component 62 near the guide member 61. Under the driving action of the seventh drive member 641, the pusher block 642 can push the material cylinder A5 in the storage trough 622 to the end away from the guide member 61. Thus, when the material cylinder A5 rolls from the guide groove 612 on the guide member 61 into the storage trough 622 of the storage component 62, the seventh drive member 641 drives the pusher block 642 to move along the storage trough 622, thereby pushing the material cylinder A5 in the storage trough 622 to the end of the storage trough 622 away from the guide member 61. When the material cylinder A5 in the storage trough 622 is full, the material cylinder A5 in the storage trough 622 can be transferred manually or by handling equipment. Alternatively, the seventh drive unit 641 may be a cylinder.

[0159] It should be noted that, in order to shorten the stroke of the material taking component 43, in some embodiments, the unloading component 60 is set as close as possible to the material preparation component 20, so that the position where the material taking shaft 431 of the material taking component 43 unloads the material cylinder A5 at the unloading component 60 is close to or the same position where the material taking shaft 431 of the material taking component 43 transfers the spare material roll A1 at the material preparation component 20. This greatly shortens the stroke of the material taking component 43, makes the roll changing device structure more compact, and improves space utilization.

[0160] Because the unloading assembly 60 and the preparation assembly 20 are close together, when the picking assembly 43 moves to the preparation assembly 20 to transfer the spare material belt A2, the feed end d1 of the guide 61 and the picking assembly 43 are prone to interference. To avoid interference between the feed end d1 of the guide 61 and the picking assembly 43, in some embodiments, the guide 61 is configured to rotate around its connecting end d2 to a receiving position and a clearance position. When the guide 61 rotates to the receiving position, the feed end d1 can receive the material cylinder A5 pushed away from the picking shaft 431 by the feeding unit 435. When the guide 61 rotates to the clearance position, the feed end d1 allows the picking shaft 431 of the picking assembly 43 to axially align with the storage shaft 22, thereby avoiding interference between the guide 61 and the picking shaft 431 of the picking assembly 43.

[0161] Furthermore, the unloading assembly 60 also includes a fifth mounting base 65 and a sixth drive member 63. The storage member 62 is fixedly connected to the fifth mounting base 65. The connecting end d2 of the guide member 61 is rotatably connected to the fifth mounting base 65. The sixth drive member 63 includes a drive member body 631 and a telescopic end 632 that can be controllably extended or retracted relative to the drive member body 631. The drive member body 631 is hinged to the fifth mounting base 65, and the telescopic end 632 is hinged to the guide member 61, thereby driving the guide member 61 to rotate between a receiving position and a clearance position by extending and retracting the telescopic end 632 relative to the drive member body 631. Optionally, the sixth drive member 63 can be a cylinder.

[0162] Optionally, when the telescopic end 632 extends relative to the drive body 631, it can drive the guide 61 to rotate to a clearance position, so that the picking shaft 431 of the picking assembly 43 can smoothly transfer the spare material roll A1 at the material preparation assembly 20. When the telescopic end 632 retracts relative to the drive body 631, it can drive the guide 61 to rotate to a receiving position, so that the material cylinder A5 on the picking shaft 431 of the picking assembly 43 can smoothly fall into the feeding end d1 of the guide 61.

[0163] Please see Figure 1 , Figure 7 , Figure 9 and Figure 10 In embodiments of this application, the rewinding device further includes a device for receiving waste roll A4 (see...) Figure 10) waste bin 50 (see Figure 1 The transfer mechanism 40 also includes a waste-retrieving component 44 mounted on the drive end of the drive assembly 41. The drive assembly 41 is also used to drive the waste-retrieving component 44 to move to the receiving roller 331 of the waste receiving assembly 33 and to the waste container 50. When the drive assembly 41 drives the waste-retrieving component 44 to move to the receiving roller 331 of the waste receiving assembly 33, the waste-retrieving 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-retrieving component 44 to move to the waste container 50, the waste-retrieving component 44 can release the waste roll A4 into the waste container 50. It should be noted that the movement of the waste-retrieving component 44 is not limited to using the drive assembly 41 to drive it. In some embodiments, a separate drive component can be configured for the waste-retrieving component 44, and this drive component can be used to drive the waste-retrieving component 44 to move, as long as the transfer of the waste roll A4 can be achieved. This is not limited here.

[0164] Specifically, the waste removal component 44 is mounted on the second transfer seat 415 of the drive component 41, so that the waste removal component 44 can move together with the second transfer seat 415 along the first direction X1 and the second direction X2, ensuring that the waste removal component 44 can accurately move to the receiving roller 331 of the waste receiving component 33 or the waste box 50.

[0165] Specifically, in this embodiment, the waste removal assembly 44 includes a second moving seat 443, a first clamping block 4453, and a second clamping block 4455. The second moving seat 443 is mounted on a second transfer seat 415 to move together with the second transfer seat 415. The first clamping block 4453 and the second clamping block 4455 are disposed on the second moving seat 443 to move together with the second moving seat 443. A receiving space j is formed between the first clamping block 4453 and the second clamping block 4455 for the receiving roller 331 to enter. The first clamping block 4453 and the second clamping block 4455 are configured to controllably move closer to or further away from each other to clamp or release the waste roll A4. A support portion 4459 and a pushing portion 4457 are provided on the sides of the first clamping block 4453 and the second clamping block 4455 facing each other. The second moving seat 443 is configured to move controllably along the axial direction of the take-up roller 331, thereby driving each pusher part 4457 to push the waste roll A4 on the take-up roller 331 axially and detach it from the take-up roller 331, and then enter the receiving space j. Each support part 4459 is used to support the waste roll A4 that has detached from the take-up roller 331 and is located in the receiving space j.

[0166] Thus, when it is necessary to remove the waste roll A4 from the take-up roller 331, firstly, the third transfer seat 416 drives the second moving seat 443 to move along the first direction X1 and / or the second direction X2 to the waste removal position, so that the receiving space j between the take-up roller 331 of the waste collection assembly 33 and the first clamping block 4453 and the second clamping block 4455 is opposite in the third direction X3. Then, the second moving seat 443 drives 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 end of the waste roll A4 away from the second moving seat 443. Then, the first clamping block 4453 and the second clamping block 4455 are brought closer together 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 waste roll A4 away from the second moving seat 443. Next, the second moving seat 443 moves away from the take-up roller 331 along a third direction X3, thereby driving the pushing part 4457 to push the waste roll A4 on the take-up roller 331 axially until the waste roll A4 is disengaged from the take-up roller 331 and supported by the various support parts 4459 between the first clamping block 4453 and the second clamping block 4455. Then, the first clamping block 4453 and the second clamping block 4455 continue to move closer together to clamp the waste roll A4, thereby preventing the waste roll A4 from loosening. Next, the third transfer seat 416 moves the second moving seat 443 along the first direction X1 and / or the second direction X2 to the waste disposal position, so that the first clamping block 4453 and the second clamping block 4455 are positioned above the waste box 50. Finally, the first clamping block 4453 and the second clamping block 4455 move 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.

[0167] Furthermore, the first clamping block 4453 is provided with multiple 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 multiple support portions 4459, which are spaced apart along the axial direction of the take-up roller 331. In this way, the support portions 4459 on the first clamping block 4453 and the multiple 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.

[0168] 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.

[0169] 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.

[0170] Furthermore, each pusher portion 4457 includes a second 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 second 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 elasticity of the second elastic element prevents damage and does not interfere 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 second elastic element is elastic, so it will not cause damage or 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.

[0171] Specifically, in this embodiment, the waste removal assembly 44 further includes a sixth mounting base 441 and an eighth driving member 442. The sixth mounting base 441 is mounted on the driving end of the driving assembly 41, enabling the driving assembly 41 to drive the sixth mounting base 441 to move along a first direction X1 and / or a second direction X2. A second moving seat 443 is movably connected to the sixth mounting base 441 along a third direction X3. The eighth driving member 442 is mounted on the sixth mounting base 441, and its driving end is connected to the second moving seat 443, enabling the eighth driving member 442 to drive the second moving seat 443 to move relative to the sixth mounting base 441 along a third direction X3. The third direction X3 is aligned with the axial direction of the receiving roller 331.

[0172] Specifically, the sixth mounting base 441 is mounted on the second transfer base 415 of the drive assembly 41, so that the sixth mounting base 441 can move together with the second transfer base 415 along the first direction X1, the second direction X2 and the third direction X3.

[0173] Thus, the second transfer seat 415 drives the sixth 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 eighth driving member 442 drives the second 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.

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.

[0175] 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.
