Description

[0002] In the battery manufacturing process, it is often necessary to continuously unwind the tape on the material roll to the downstream. For example, in the winding process of the battery cell, the electrode sheet needs to be continuously unwound and output to the winding device. When the working tape on the working material roll is unwound, it is necessary to cut the working tape and then connect the working tape with the spare tape of the spare material roll, so as to continue to unwind and output the tape downstream, that is, to complete the roll change.

[0003] In the prior art, in order to achieve a smooth connection between the working material tape and the spare material tape, it is necessary to manually pull the starting end of the material tape on the spare material roll to a specified state, and to cut, affix double-sided tape, and other processing to the starting end of the material tape.

[0068] See also Figure 1 The present application provides a roll changing device, including a glue preparation mechanism 10, a roll unwinding mechanism 31, a tape connection mechanism 30 and a transfer mechanism 40.

[0069] The adhesive preparation mechanism 10 is used to provide adhesive tape e (see Figure 2 ). The unwinding mechanism 31 is used to load the working material roll and the spare material roll A1 (see Figure 6), and drives the working material roll thereon to unwind and output the working material tape downstream. The transfer mechanism 40 includes a driving component 41 and a glue taking component 42 installed on the driving end of the driving component 41. The driving component 41 is used to drive the glue taking component 42 to move, so that the glue taking component 42 can move to the glue preparation mechanism 10, the tape connection mechanism 30 and the unwinding mechanism 31. When the glue taking component 42 moves to the glue preparation mechanism 10, it can pick up the adhesive tape e provided by the glue preparation mechanism 10, and when the glue taking component 42 moves to the tape connection mechanism 30, it can release the picked-up adhesive tape e to the tape connection mechanism 30, that is, the glue taking component 42 can realize the transfer of the adhesive tape e provided by the glue preparation mechanism 10 to the tape connection mechanism 30. When the adhesive taking component 42 moves to the unwinding mechanism 31, it can use the adhesive tape e to stick the starting end A3 of the spare material roll A1 on the unwinding mechanism 31, and pull the starting end A3 of the material roll through the tape splicing mechanism 30, so that the tape splicing mechanism 30 can fix the spare material roll A2, and prepare for the subsequent roll change. The tape splicing mechanism 30 is arranged downstream of the unwinding mechanism 31, and is used to cut off the passing working material roll and the spare material roll A2 when the working material roll is unwound, and use the adhesive tape e to stick the downstream cut end of the working material roll and the upstream cut end of the spare material roll A2, so as to realize the mutual connection of the downstream cut end of the working material roll and the upstream cut end of the spare material roll A2, that is, to realize the tape splicing.

[0070] In the above-mentioned roll changing device, during the actual roll changing operation, the driving component 41 drives the glue taking component 42 to transfer the adhesive tape e provided by the adhesive preparation mechanism 10 to the tape splicing mechanism 30, and also drives the glue taking component 42 to use the adhesive tape e to stick the tape starting end A3 of the spare material roll A1 on the unwinding mechanism 31, and pull the tape starting end A3 through the tape splicing mechanism 30. When the working material roll on the unwinding mechanism 31 is used up, the tape splicing mechanism 30 cuts off the working material tape and the spare material tape A1, and uses the adhesive tape e to stick the downstream cut end of the working material tape to the upstream cut end of the spare material tape A2, thereby realizing the connection between the spare material tape A2 and the working material tape. At this time, the spare material roll A1 on the unwinding mechanism 31 is switched to the working material roll, and the working material tape is continuously unwound and output to the downstream.

[0071] In this way, the roll changing device of the present application can automatically complete the transfer of tape e, the starting processing and threading of the spare material tape A2, the bonding of the working material tape and the spare material tape A2, and other actions, thereby realizing automatic roll changing. There is no need for manual processing of the tape e and the spare material roll A1, etc., which is beneficial to improving the degree of automation of the roll changing equipment, improving the roll changing efficiency, eliminating the need for personnel on duty, and reducing labor costs.

[0072] In the embodiment of the present application, the tape splicing mechanism 30 includes a tape splicing assembly 32 and a waste material receiving assembly 33. The unwinding mechanism 31 is used to unwind the working tape to the tape splicing assembly 32 and receive the spare material roll A1 transferred by the material taking assembly 43. The tape splicing assembly 32 is arranged downstream of the unwinding mechanism 31, and the waste material receiving assembly 33 is arranged downstream of the tape splicing assembly 32. Under the driving action of the driving assembly 41, the adhesive taking assembly 42 can pull the starting end A3 of the tape on the spare material roll A1 to pass through the tape splicing assembly 32 and the waste material receiving assembly 33 in sequence, so that the waste material receiving assembly 33 fixes and rewinds the spare material tape A2 passing through. The tape splicing assembly 32 is used to cut the working tape and spare material tape A2 passing through, and use the adhesive tape e to bond the downstream cut end of the working tape and the upstream cut end of the spare material tape A2, so as to realize the mutual connection between the downstream cut end of the working tape and the upstream cut end of the spare material tape A2, that is, to realize the tape splicing.

[0073] Thus, in actual use, first, the driving component 41 drives the glue taking component 42 to move to the glue preparation mechanism 10, so that the glue taking component 42 picks up the adhesive tape e provided by the glue preparation mechanism 10 at the glue preparation mechanism 10. Then, the driving component 41 drives the glue taking component 42 to move to the unwinding mechanism 31, so that the glue taking component 42 uses the adhesive tape e to stick to the starting end A3 of the spare material roll A1 on the unwinding mechanism 31. Then, the driving component 41 drives the glue taking component 42 to pass through the splicing component 32 and the waste collecting component 33 in sequence, thereby pulling out the spare material tape A2 on the spare material roll A1, so that the pulled spare material tape A2 passes through the splicing component 32 and the waste collecting component 33 in sequence, and is fixed on the waste collecting component 33. On the one hand, the splicing component 32 can simultaneously cut off the working material tape and the spare material tape A2 when changing the rolls. On the other hand, after the spare material tape A2 is cut off, the part between the splicing component 32 and the waste collecting component 33 becomes waste. The waste collecting component 33 can reel up the waste and form a waste roll A4, thereby preventing the waste from interfering with the splicing action of the splicing component 32.

[0074] It can be understood that the unwinding mechanism 31, the tape connecting assembly 32 and the waste material collecting assembly 33 cooperate with each other to cut the working material tape and the spare material tape A2, and use the tape e to bond the downstream cut end of the working material tape and the upstream cut end of the spare material tape A2. This is a relatively mature existing technology, so it will not be elaborated here.

[0075] It should be emphasized that after the working material belt is cut, two cut ends are formed at the fracture, of which the one located upstream is the upstream cut end, and the one located downstream is the downstream cut end. Similarly, after the spare material belt A2 is cut, two cut ends are formed at the fracture, of which the one located upstream is the upstream cut end, and the one located downstream is the downstream cut end. The upstream and downstream in this article are relative to the conveying path of the material belt. The position where the material belt arrives first is the upstream, and the position where the material belt arrives later is the downstream.

[0076] It should be noted that after the splicing assembly 32 cuts the working material tape, the portion of the working material tape between the splicing assembly 32 and the unwinding mechanism 31 is also waste material. The unwinding mechanism 31 can be used to reel up this portion of waste material to prevent this portion of waste material from interfering with the splicing work of the splicing assembly 32.

[0077] See also Figures 1 to 3 As shown, in the embodiment, the glue taking component 42 has a glue sucking roller 421 that can rotate around its own axis. The glue taking component 42 can fix the starting end of the adhesive tape e by using the glue sucking roller 421 at the adhesive preparation mechanism 10 and wind the adhesive tape e. The adhesive preparation mechanism 10 is used to cut the adhesive tape e, so that a certain length of the adhesive tape e is wound on the adhesive sucking roller 421.

[0078] It should be noted that in the prior art, a certain length of adhesive tape e is pulled out by a glue pulling mechanism onto an adhesive suction board, and the pulled out adhesive tape e is cut off, and then the adhesive tape e on the adhesive suction board is transferred to a designated position. Compared with the prior art, in this embodiment, the adhesive suction roller 421 is used to fix the starting end of the adhesive tape e, and a certain length of adhesive tape e is wound and then cut off, thereby realizing the picking up and transfer of the adhesive tape e, and there is no need for a glue pulling mechanism to pull adhesive and an adhesive suction board to suck adhesive, which greatly saves the space required, and the structure is more compact, so that the roll changing device is more suitable for working conditions with limited space.

[0079] See also Figure 4 , further, the tape splicing component 32 has a glue absorbing surface f for absorbing the adhesive tape e. The adhesive taking component 42 can move to the tape splicing component 32 under the driving action of the driving component 41, and make the adhesive absorbing roller 421 abut against the adhesive absorbing surface f, so that the adhesive absorbing surface f absorbs the adhesive tape e on the adhesive absorbing roller 421. The adhesive taking component 42 can also drive the adhesive absorbing roller 421 to roll along the adhesive absorbing surface f under the driving action of the driving component 41, so that the adhesive tape e is flattened and laid on the adhesive absorbing surface f, until the adhesive tape e is completely separated from the adhesive absorbing roller 421, that is, the adhesive tape e is transferred to the adhesive absorbing surface f of the tape splicing component 32.

[0080] See also Figure 5 Furthermore, the adhesive taking component 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 tape e on the adhesive suction roller 421 is bonded to the material tape starting end A3 on the spare material roll A1, and the spare material tape A2 is wound by rotating itself. Under the driving action of the driving component 41, the adhesive taking component 42 can also use the adhesive suction roller 421 to pull the material tape starting end A3 through the tape splicing component 32 and the waste material collecting component 33 in sequence, so that the spare material tape A2 of the spare material roll A1 passes through the tape splicing component 32 and is fixed on the waste material collecting component 33.

[0081] It should be noted that the two sides of the adhesive tape e are respectively the adhesive surface and the non-adhesive surface. Therefore, the direction of the adhesive surface of the adhesive tape e wound on the adhesive tape roller 421 can be controlled by adjusting the rotation direction of the adhesive tape roller 421. In other words, when the adhesive tape roller 421 is controlled to rotate in the first direction (i.e. Figure 2 When the adhesive roller 421 rotates in the counterclockwise direction (in the embodiment shown), the adhesive surface of the adhesive tape e wound on the adhesive suction roller 421 is located on the outside and does not contact the adhesive suction roller 421, and the non-adhesive surface is located on the inside and contacts the roller surface of the adhesive suction roller 421. When the adhesive suction roller 421 is controlled to rotate along the second rotation direction (the second rotation direction is opposite to the first rotation direction), the adhesive surface of the adhesive tape e wound on the adhesive suction roller 421 is located on the inside and contacts the roller surface of the adhesive suction roller 421, and the non-adhesive surface is located on the outside and does not contact the adhesive suction roller 421.

[0082] When it is necessary to stick the starting end A3 of the tape on the standby material roll A1, the driving assembly 41 drives the glue taking assembly 42 to move to the glue preparation mechanism 10, so that the glue suction roller 421 fixes the starting end of the adhesive tape e. The glue suction roller 421 is controlled to rotate along the first rotation direction until a certain length of the adhesive tape e is driven to be wound onto the glue suction roller 421. Then, the glue preparation mechanism 10 is controlled to cut the adhesive tape e. Then, the driving assembly 41 drives the glue taking assembly 42 to move to the unwinding mechanism 31, so that the glue suction roller 421 is pressed against the starting end A3 of the tape on the standby material roll A1. At this time, since the adhesive surface of the adhesive tape e on the glue suction roller 421 is located on the outside, the adhesive tape e and the starting end A3 of the tape on the standby material roll A1 are bonded and fixed to each other. Then, the glue suction roller 421 rotates around its own axis, thereby driving the standby material tape A2 on the standby material roll A1 to be wound onto the glue suction roller 421. Then, under the driving action of the driving component 41, the adhesive suction roller 421 pulls the spare material tape A2 on the spare material roll A1 to pass through the tape connection component 32 and the waste material collection component 33 in sequence, and the waste material collection component 33 fixes the spare material tape A2 passing through. Finally, the adhesive suction roller 421 is controlled to rotate along the second rotation direction until the material tape starting end A3 of the spare material tape A2 and the adhesive tape e are completely separated from the adhesive suction roller 421.

[0083] When it is necessary to transfer the adhesive tape e to the adhesive suction surface f of the tape splicing component 32, the driving component 41 drives the adhesive taking component 42 to move to the adhesive preparation mechanism 10, so that the adhesive suction roller 421 fixes the starting end of the adhesive tape e. The adhesive suction roller 421 is controlled to rotate along the second rotation direction until a certain length of the adhesive tape e is driven to be wound onto the adhesive suction roller 421. At this time, the adhesive surface of the adhesive tape e on the adhesive suction roller 421 is located on the inner side. Then, the adhesive preparation mechanism 10 is controlled to cut the adhesive tape e. Then, the driving component 41 drives the adhesive taking component 42 to move to the tape splicing component 32, so that the adhesive suction roller 421 is pressed against the adhesive suction surface f. Then, under the driving action of the driving component 41, the adhesive suction roller 421 rolls along the adhesive suction surface f, and the rotation direction of the adhesive suction roller 421 is the first rotation direction, until the adhesive tape e is completely flattened and laid on the adhesive suction surface f and is completely separated from the adhesive suction roller 421. At this time, the adhesive surface of the tape e is away from the adhesive absorbing surface f, and the non-adhesive surface of the tape e is facing the adhesive absorbing surface f, and is adsorbed and fixed by the adhesive absorbing surface f, so that the tape e can be subsequently pasted between the downstream cut end of the working material tape and the upstream cut end of the spare material tape A2.

[0084] See also Figures 11 to 14 Specifically, in the embodiment, the waste collecting assembly 33 includes a first moving seat 334, a second rotating driving member 336 and a collecting roller 331. The second rotating driving member 336 is mounted on the first moving seat 334 to move with the first moving seat 334. The collecting roller 331 is mounted on the first moving seat 334 and connected to the driving end of the second rotating driving member 336, so that the second rotating driving member 336 can drive the collecting roller 331 to rotate around its own axis.

[0085] The receiving roller 331 has an insertion slot k, and the first moving seat 334 can controllably drive the receiving roller 331 to move along its own axis, so that the spare material tape A2 that follows the adhesive suction roller 421 to the waste material receiving assembly 33 enters the insertion slot k. After the spare material tape A2 enters the insertion slot k of the receiving roller 331, the second rotating driving member 336 drives the receiving roller 331 to rotate, thereby driving the spare material tape A2 to be wound around the receiving roller 331. Optionally, the second rotating driving member 336 can be a motor.

[0086] Thus, in actual use, first, the first moving seat 334 drives the receiving roller 331 to move along its own axis (ie, Figure 1 ) to the avoidance position, so as to avoid the material collection roller 331 from interfering with the rubber suction roller 421 when the rubber suction roller 421 pulls the material starting end A3 of the spare material tape A2 to move. Then, the rubber suction roller 421 pulls the material starting end A3 of the spare material tape A2 on the spare material roll A1 to pass through the tape connection assembly 32 and the waste material collection assembly 33 in sequence. Then, the first moving seat 334 drives the material collection roller 331 to move along its own axis (i.e., as shown in FIG. 1 ). Figure 1) to the winding position, so that the spare tape A2 passing through the waste material collection component 33 enters the insertion slot k of the receiving roller 331. Then, the glue suction roller 421 is controlled to rotate and unwind the starting end A3 of the spare tape A2 and the adhesive tape e, until the glue suction roller 421 is separated from the starting end A3 of the spare tape A2 and the adhesive tape e. At the same time, the second rotating drive member 336 drives the receiving roller 331 to rotate and rewind the spare tape A2 on the receiving roller 331, until the starting end A3 of the spare tape A2 and the adhesive tape e are both rewound on the receiving roller 331. It should be noted that the spare tape A2 and the adhesive tape e rewound on the receiving roller 331 are the waste material roll A4.

[0087] Furthermore, the waste material receiving assembly 33 further includes a material 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 described below, and is arranged at intervals from the receiving roller 331, and the pressing block 3322 is movably connected to the side of the connecting seat 3321 facing the receiving 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 material roll A4 wound on the receiving roller 331 under the elastic force provided by the first elastic member 3323. In this way, the spare material belt A2 (i.e., the waste material roll A4) wound on the receiving roller 331 is pressed against the receiving roller 331 by the pressing block 3322, so as to prevent the waste material roll A4 on the receiving roller 331 from loosening or even falling off. Optionally, the first elastic member 3323 may be a compression spring.

[0088] Furthermore, the waste material collecting assembly 33 further includes a guide rod 3324, a matching plate 3326 and a stop block 3325. A guide hole is provided on the connecting seat 3321, and the guide rod 3324 is inserted into the guide hole. One end of the guide rod 3324 facing the collecting roller 331 is fixedly connected to the pressing block 3322, and one end of the guide rod 3324 facing away from the collecting roller 331 is fixedly connected to the matching plate 3326. The stop block 3325 is installed on the connecting seat 3321, and the matching plate 3326 has a movement tendency to press against the stop block 3325 under the elastic force provided by the first elastic member 3323. In this way, when the waste roll A4 is not wound on the receiving roller 331, the matching plate 3326 abuts against the limit block 3325 under the elastic force provided by the first elastic member 3323, so that the limit block 3325 is used to limit the pressing block 3322, so as to prevent the pressing block 3322 from directly pressing against the receiving roller 331, thereby preventing the receiving roller 331 from bending and deforming due to long-term stress. When the waste roll A4 is wound on the receiving roller 331, the pressing block 3322 presses against the waste roll A4 on the receiving roller 331. As the diameter of the waste roll A4 gradually increases, the pressing block 3322 gradually overcomes the elastic force of the first elastic member 3323 and moves toward the connecting seat 3321, thereby driving the matching plate 3326 to gradually move away from the limit block 3325.

[0089] Furthermore, the position of the limit block 3325 on the connecting seat 3321 is adjustable, so that the gap between the pressure block 3322 and the receiving roller 331 can be adjusted by adjusting the position of the limit block 3325, ensuring that there is a certain gap between the pressure block 3322 and the receiving roller 331 when there is no waste roll A4 being wound on the receiving roller 331, and the pressure block 3322 is pressed against the waste roll A4 when there is waste roll A4 being wound on the receiving roller 331.

[0090] Optionally, a waist-shaped hole 3327 is provided on the limit block 3325, and the waste collecting assembly 33 further includes a locking bolt (not shown). The locking bolt passes through the waist-shaped hole 3327 on the limit block 3325 and is threadedly connected to the connecting seat 3321, thereby locking and fixing the limit block 3325 on the connecting seat 3321. In this way, the position of the limit block 3325 can be adjusted by the cooperation of the locking bolt and the waist-shaped hole 3327.

[0091] Specifically in the embodiment, the roll changing device further includes a mounting plate 70, and the receiving roller 331 is rotatable around its own axis and movably connected to the mounting plate 70 along its own axial direction. The waste receiving assembly 33 further includes a moving driving member 335, which is installed between the first moving seat 334 and the mounting plate 70, and is used to drive the first moving seat 334 to move along the axial direction of the receiving roller 331 relative to the mounting plate 70, thereby driving the receiving roller 331 to move between the avoidance position and the winding position. Optionally, the moving driving member 335 can be a cylinder.

[0092] Furthermore, the waste material collecting assembly 33 further includes a guide member 337 and a sleeve 338, and the sleeve 338 is mounted on the mounting plate 70 through the guide member 337, so that the sleeve 338 can move along its own axial direction relative to the mounting plate 70. The receiving roller 331 is sleeved inside the sleeve 338 and can rotate relative to the sleeve 338 around its own axis. One end of the receiving roller 331 is connected to the drive of the second rotating driving member 336, and the other end of the receiving roller 331 passes through the sleeve 338 and is used to reel in the spare material strip A2 passing through. The insertion groove k is located at the portion of the receiving roller 331 passing through the sleeve 338. Optionally, the guide member 337 can be a linear bearing.

[0093] Please also see Figure 6 It should be noted that the unwinding mechanism 31 includes two unwinding units, and the tape splicing assembly 32 includes two tape splicing units. A tape splicing channel g is formed between the two tape splicing units. The two unwinding units are located on the same side of the two tape splicing units. Both unwinding units can load material rolls (i.e., working material rolls or spare material rolls A1) and unwind and output material tapes (i.e., working material tapes or spare material tapes A2) to the tape splicing channel g. When the material roll loaded on one of the unwinding units is a working material roll, the material tape unwinded and output by the unwinding unit to the tape splicing channel g is a working material tape, and the working material tape continues to be transported downstream after passing through the tape splicing channel g, wherein the material roll loaded on the other unwinding unit is a spare material roll A1, and the material tape starting end A3 of the spare material roll A1 passes through the tape splicing channel g and the material receiving roller 331 of the waste material receiving assembly 33 under the traction of the rubber suction roller 421, and is then fixed on the material receiving roller 331.

[0094] One unwinding unit and one tape splicing unit on the same side form a group, namely the first unwinding unit 31a and the first tape splicing unit 32a. Another unwinding unit and another tape splicing unit on the same side form another group, namely the second unwinding unit 31b and the second tape splicing unit 32b.

[0095] It should be noted that the working material roll in this article refers to the material roll that is being unwound and output to the downstream as the working material roll, and the material tape that the working material roll unwound and output to the downstream is the working material tape. The standby material roll in this article refers to the material roll that has not yet been unwound and output to the downstream, and the tape on the standby material roll is the standby material tape. For example, when the material roll on the first unwinding unit 31a is the working material tape, the first unwinding unit 31a drives the working material roll on it to rotate, thereby conveying the working material tape downstream. The working material tape continues to be conveyed downstream after passing through the tape connection channel g. At this time, the material roll on the second unwinding unit 32a is the standby material roll.

[0096] When the working material roll on the first unwinding unit 31a is unwound, it is necessary to change the roll. After the roll change is completed, the spare roll on the second unwinding unit 31a is switched to the working material roll, and the working material tape is continuously unwound and outputted downstream. At this time, the material taking component 43 transfers the spare roll to the first unwinding unit 31a and prepares for the next roll change.

[0097] In order to save space, the distance between the first unwinding unit 31a and the second unwinding unit 31b is small, and the distance between the first tape unit 32a and the second tape unit 32b is also small. Therefore, when the adhesive suction roller 421 pulls the starting end A3 of the material tape of the spare material roll A1 on the first unwinding unit 31a through the tape splicing channel g and reaches the downstream of the material receiving roller 331, the second unwinding unit 31b and the second tape splicing unit 32b are likely to interfere with the adhesive suction roller 421. Similarly, when the adhesive suction roller 421 pulls the starting end A3 of the material tape of the spare material roll A1 on the second unwinding unit 31b through the tape splicing channel g and reaches the downstream of the material receiving roller 331, the first unwinding unit 31a and the first tape splicing unit 32a are also likely to interfere with the adhesive suction roller 421.

[0098] In order to solve the problem of interference with the glue suction roller 421, in some embodiments, the first unwinding unit 31a is constructed to be controllably movable along the axial direction of the receiving roller 331. The first tape unit 32a can be controllably connected to or separated from the first unwinding unit 31a. When the first tape unit 32a is connected to the first unwinding unit 31a, the first tape unit 32a can move along the axial direction of the receiving roller 331 along with the first unwinding unit 31a. The second unwinding unit 31a is also constructed to be controllably movable along the axial direction of the receiving roller 331. The second tape unit 32b can be controllably connected to or separated from the second unwinding unit 31b. When the second tape unit 32b is connected to the second unwinding unit 31b, the second tape unit 32b can move along the axial direction of the receiving roller 331 along with the second unwinding unit 31b. It should be noted that a linear drive component such as an electric cylinder or a screw module may be used to drive the first unwinding unit 31a to move along the axial direction of the receiving roller 331, which is not limited here. A linear drive component such as an electric cylinder or a screw module may be used to drive the second unwinding unit 31b to move along the axial direction of the receiving roller 331, which is not limited here.

[0099] Further, the first belt unit 32a and the second belt unit 32b can be selectively connected to the first moving seat 334. When the first belt unit 32a is connected to the first moving seat 334, the second belt unit 32b is separated from the first moving seat 334, so that the receiving roller 331 and the first belt unit 32a can be synchronously moved along the axial direction of the receiving roller 331. When the second belt unit 32b is connected to the first moving seat 334, the first belt unit 32a is separated from the first moving seat 334, so that the receiving roller 331 and the second belt unit 32b can be synchronously moved along the axial direction of the receiving roller 331.

[0100] Thus, when the material roll on the first unwinding unit 31a is the spare material roll A1, the first tape connection unit 32a is controlled to connect with the first unwinding unit 31a. At this time, the first unwinding unit 31a is controlled to move along the axial direction of the receiving roller 331 (i.e., along the Figure 1 The first moving seat 334 moves along the axial direction of the take-up roller 331, thereby also driving the first tape connection unit 32a to move along the axial direction of the take-up roller 331, so that the first unwinding unit 31a and the second unwinding unit 31b are misaligned in the axial direction of the take-up roller 331, and the first tape connection unit 32a and the second tape connection unit 32b are also misaligned in the axial direction of the take-up shaft 331, ensuring that the glue suction roller 421 will not interfere with the second unwinding unit 31b, the second tape connection unit 32b and the take-up roller 331 during the process of pulling the starting end A3 of the spare tape A2 on the first unwinding unit 31a through the tape connection channel g and reaching the downstream of 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 along the axial direction of the take-up roller 331 (i.e., along the Figure 1 The first unwinding unit 31a, the first tape connecting unit 32a and the receiving roller 331 move outward in a direction perpendicular to the paper surface, thereby driving the receiving roller 331 to move to the rewinding position, so that the receiving roller 331 fixes and rewinds the spare tape A2. Finally, the first moving seat 334 is controlled to be connected with the first tape connecting unit 32a, so that the first unwinding unit 31a, the first tape connecting unit 32a and the receiving roller 331 move together along the axial direction of the receiving roller 331 and reset (i.e., along the Figure 1 The two unwinding units, the two tape splicing units and the waste material receiving assembly cooperate with each other to complete the tape splicing.

[0101] When the material roll on the second unwinding unit 31b is the spare material roll A1, the second tape connection unit 32b is controlled to connect with the second unwinding unit 31b. At this time, the second unwinding unit 31b is controlled to move along the axial direction of the receiving roller 331 (i.e., along the Figure 1The second unwinding unit 31b is moved outward in a direction perpendicular to the paper surface to the threading position, and at the same time, the second tape connecting unit 32b is driven to move along the axial direction of the material receiving roller 331, so that the second unwinding unit 31b is misaligned with the first unwinding unit 31a in the axial direction of the material receiving roller 331, and the second tape connecting unit 32b is also misaligned with the first tape connecting unit 32a in the axial direction of the material receiving shaft 331, thereby ensuring that when the glue suction roller 421 pulls the starting end A3 of the spare material tape A2 on the second unwinding unit 31b through the tape connecting channel g and reaches the downstream of the material receiving roller 331, it will not interfere with the first unwinding unit 31a, the first tape connecting unit 32a and the material receiving roller 331. After the rubber suction roller 421 pulls the starting end A3 of the spare material tape A2 to the downstream of the receiving roller 331, the first moving seat 334 moves along the axial direction of the receiving roller 331, thereby driving the receiving roller 331 to move to the reeling position, so that the receiving roller 331 can fix and reel the spare material tape A2. Finally, the first moving seat 334 is controlled to connect with the second tape connection unit 32b, so that the second unwinding unit 31b, the second tape connection unit 32b and the receiving roller 331 move together along the axial direction of the receiving roller 331 and reset (i.e., along the receiving roller 331). Figure 1 The two unwinding units, the two tape splicing units and the waste material receiving assembly 33 cooperate with each other to complete the tape splicing.

[0102] Specifically, the belt connecting mechanism 30 further includes a first clutch assembly 34, which includes a clutch slide 342 and a clutch drive 341. The clutch slide 342 is movably connected to the first moving seat 334. The clutch drive 341 is installed on the first moving seat 334, and the driving end of the clutch drive 341 is connected to the clutch slide 342. The clutch drive 341 can drive the clutch slide 342 to move relative to the first moving 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.

[0103] It should be noted that, in some embodiments, a matching groove or hole is provided on the clutch slide 342. When the clutch slide 342 moves to the first position, part of the first belt connecting unit 32a is inserted into the matching groove or hole, thereby realizing the connection between the first belt connecting unit 32a and the clutch slide 342, so that the first moving seat 334 can drive the first belt connecting unit 32a to move along the axial direction of the receiving roller 331. When the clutch slide 342 moves to the second position, part of the second belt connecting unit 32b is inserted into the matching groove or hole, thereby realizing the connection between the second belt connecting unit 32b and the clutch slide 342, so that the first moving seat 334 can drive the second belt connecting unit 32b to move along the axial direction of the receiving roller 331. Of course, in other embodiments, the clutch slide 342 and the first belt connecting unit 32a or the second belt connecting unit 32b can also be connected in other ways, such as clamping, which is not limited here.

[0104] Specifically, the tape splicing 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 splicing unit 32a, and the first unwinding unit 31a is connected or separated from the first tape splicing unit 32a by the second clutch assembly. The third clutch assembly 36 is disposed between the second unwinding unit 31b and the second tape splicing unit 32b, and the second unwinding unit 31b is connected or separated from the second tape splicing unit 32b by the third clutch assembly 36.

[0105] Further, the second clutch assembly includes a first clamping portion and a first connecting portion, one of which is mounted on the first unwinding unit 31a, and the other of which is mounted on the first tape connecting 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 connecting 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 synchronously move along the axial direction of the receiving roller 331. When the first clamping portion releases the first connecting portion, the first tape connecting unit 32a is separated from the first unwinding unit 31a and cannot move together along the axial direction of the receiving roller 331. It should be noted that the first clamping portion can adopt a clamping claw structure, as long as it can clamp or release the first connecting portion, and is not limited here.

[0106] Further, the third clutch assembly 36 includes a second clamping portion 361 and a second connecting portion 362, one of which is mounted on the second unwinding unit 31b, and the other of which is mounted on the second tape connecting 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 connecting 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 synchronously move along the axial direction of the receiving roller 331. When the second clamping portion 361 releases the second connecting portion 362, the second tape connecting unit 32b is separated from the second unwinding unit 31b and cannot move together along the axial direction of the receiving roller 331. It should be noted that the second clamping portion 361 can adopt a clamping claw structure, as long as it can clamp or release the second connecting portion 362, and is not limited here.

[0107] It should be noted that the first unwinding unit 31a is not limited to driving the first splicing unit 32a to move the first splicing unit 32a along the axial direction of the receiving roller 331. In other embodiments, a driving component may be provided to drive the first splicing unit 32a to move along the axial direction of the receiving roller 331.

[0108] Similarly, the second unwinding unit 31a is not limited to driving the second splicing unit 32b to move the second splicing unit 32b axially along the receiving roller 331. In other embodiments, a driving component may be provided to drive the second splicing unit 32b to move axially along the receiving roller 331.

[0109] It should also be noted that, since the spare material roll A1 may be on the first unwinding unit 31a or on the second unwinding unit 31b, in order to avoid the spare material tape A2 interfering with the conveying of the working material tape downstream, in some embodiments, the waste material collecting assembly 33 is provided with two receiving rollers 331, the two receiving rollers 331 are respectively the first receiving roller and the second receiving roller, the first receiving roller is located on the same side as the first unwinding unit 31a and the first tape connecting unit 32a, and the second receiving roller is located on the same side as the second unwinding unit 31b and the second tape connecting unit 32b. In this way, when the spare material roll A1 is located on the first unwinding unit 31a, the spare material tape 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 connecting unit 32a in sequence, and is wound onto the first receiving roller. When the standby material roll A1 is located on the second unwinding unit 31b, the standby material tape A2 of the standby material roll A1 pulled out by the glue suction roller 421 passes through the second unwinding unit 31b and the second tape connection unit 32b in sequence, and is wound onto the second material winding roller.

[0110] It should be noted that, in some embodiments, the two receiving rollers 331 can be driven by two second rotating driving members 336 respectively, so that the two receiving rollers 331 can rotate around their respective axes. Of course, in some other embodiments, the two receiving rollers 331 can also be driven to rotate synchronously by one second rotating driving member 336. Specifically, the waste collecting assembly 33 also includes a driving wheel L1, a driven wheel L2 and a transmission belt L3, the driving wheel L1 and the driven wheel L2 are respectively installed on the two receiving rollers 331, the transmission belt L3 is sleeved between the driving wheel L1 and the driven wheel L2, and the driving end of the second rotating driving member 336 is connected to one of the receiving rollers 331, so that when one of the receiving rollers 331 rotates under the driving action of the second rotating driving member 336, the other receiving roller 331 can be driven to rotate synchronously through the driving wheel L1, the transmission belt L3 and the driven wheel L2. In this way, the two receiving rollers 331 share one second rotating driving member 336, which is conducive to reducing the cost of the device.

[0111] See also Figures 6 to 8In some embodiments, the glue taking component 42 includes a first mounting seat 418, a first rotating driving member 422 and a first rotating seat 423. The first mounting seat 418 is mounted on the driving end of the driving component 41, so that the driving component 41 can drive the first mounting seat 418 to move. The first rotating driving member 422 is mounted on the first mounting seat 418, and the first rotating seat 423 is mounted on the driving end of the first rotating driving member 422, so that the first rotating driving member 422 can drive the first rotating seat 423 to rotate. The above-mentioned glue suction roller 421 is mounted on the first rotating seat 423, so that the glue suction roller 421 can rotate with the first rotating seat 423.

[0112] The driving assembly 41 is used to drive the first mounting seat 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, and the first rotating driving member 422 is used to drive the first rotating seat 423 to rotate around the axis of the glue suction roller 421. The first direction X1, the second direction X2 and the third direction X3 intersect each other, and the third direction X3 is consistent with the axial direction of the glue suction roller 421. In this way, the first mounting seat 418 is driven by the driving assembly 41 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, so that the first mounting seat 418 can accurately drive the glue suction roller 421 to pick up the adhesive tape e at the glue preparation mechanism 10, release the adhesive tape e to the adhesive suction surface f at the tape splicing assembly 32, pick up the starting end A3 of the material tape on the spare material roll A1 at the unwinding mechanism 31, and pull the spare material tape A2 to pass through the tape splicing assembly 32 and the waste material collection assembly 33 in sequence. The first rotary driving member 422 drives the adhesive suction roller 421 to rotate around its own axis (ie, the adhesive suction roller 421 rotates along the first rotation direction or the second rotation direction), thereby winding or releasing the adhesive tape e or the spare material tape A2.

[0113] Specific to 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, and the third direction X3 is consistent with the axial direction of the glue suction roller 421. It should be noted that the third direction X3 is consistent with the axial direction of the glue suction roller 421 means that the third direction X3 is substantially parallel to the axial direction of the glue suction roller 421.

[0114] Specifically, the glue picking assembly 42 also includes a first slide 424 and a second slide 425 both disposed on the first rotating seat 423. The glue suction 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 that are opposite to each other are combined 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 away from each other to clamp or release the starting end of the adhesive tape e. In this way, when it is necessary to pick up the adhesive tape e provided by the adhesive preparation mechanism 10, first, the first slide 424 and the second slide 425 drive the first adsorption half roller 4211 and the second adsorption half roller 4213 to move away from each other. The driving component 41 drives the glue taking component 42 to move to the glue preparation mechanism 10, so that the starting end of the adhesive tape e is inserted between the first adsorption half roller 4211 and the second adsorption half roller 4213. Then, the first slide 424 and the second slide 425 drive the first adsorption half roller 4211 and the second adsorption half roller 4213 to approach each other until the starting end of the adhesive tape e between the two is clamped. Then, the first rotating driving member 422 drives the first adsorption half roller 4211 and the second adsorption half roller 4213 to rotate along the first rotation direction or the second rotation direction until a certain length of the adhesive 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 adhesive tape e, so that the adhesive suction roller 421 picks up a certain length of the adhesive 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 one of the first slide 424 and the second slide 425 may be movable while the other one is not movable, as long as the first adsorption half roller 4211 and the second adsorption half roller 4213 can be driven to clamp or release the starting end of the adhesive tape e. This is not limited here. For ease of understanding, this article takes the example that both the first slide 424 and the second slide 425 are movable for explanation.

[0115] Furthermore, the surfaces of the first adsorption half roller 4211 and the second adsorption half roller 4213 facing away from each other are both adsorption surfaces h, and the adsorption surface h is used to adsorb the adhesive tape e wound on the adsorption surface h, so as to prevent the adhesive tape e wound on the first adsorption half roller 4211 and the second adsorption half roller 4213 from loosening or even falling. Optionally, the adsorption surface h can be adsorbed and fixed to the adhesive tape e by vacuum adsorption. Specifically, a plurality of adsorption holes are provided on the adsorption surface h, and each adsorption hole is connected to an external negative pressure source, so that the external negative pressure source can form negative pressure at each adsorption hole, and then use the negative pressure to adsorb and fix the adhesive tape e on the adsorption surface h.

[0116] Furthermore, the glue taking assembly 42 further includes a first clamping driving member 426 and a second clamping driving member 427 both mounted on the first rotating seat 423. The driving end of the first clamping driving member 426 is connected to the first sliding seat 424, so that the first clamping driving member 426 can drive the first sliding seat 424 to approach or move away from the second sliding seat 425, thereby causing the first sliding seat 424 to drive the first adsorption half roller 4211 to approach or move away from the second adsorption half roller 4213. The driving end of the second clamping driving member 427 is connected to the second sliding seat 425, so that the second clamping driving member 427 can drive the second sliding seat 425 to approach or move away from the first sliding seat 424, thereby causing the second sliding seat 425 to drive the second adsorption half roller 4213 to approach or move away from the first adsorption half roller 4211. Optionally, both the first clamping driving member 426 and the second clamping driving member 427 can be cylinders.

[0117] In this way, when the glue suction roller 421 needs to clamp the tape e at the glue preparation mechanism 10, the first clamping drive component 426 drives the first adsorption half roller 4211 to move close to the second adsorption half roller 4213, and at the same time the second clamping drive component 427 also drives the second adsorption half roller 4213 to move close 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 the two.

[0118] When the first adsorption half roller 4211 of the adhesive absorbing roller 421 abuts against the adhesive absorbing surface f of the tape connecting assembly 32, and the adhesive tape e needs to be loosened, the second clamping driving member 427 drives the second adsorption half roller 4213 away from the first adsorption half roller 4211, thereby loosening the adhesive tape e. At this time, the first clamping driving member 426 does not drive the first adsorption half roller 4211 to move, thereby preventing the first adsorption half roller 4211 from pressing against the adhesive absorbing surface f too much and damaging the adhesive tape e.

[0119] When the second adsorption half roller 4213 of the adhesive absorbing roller 421 abuts against the adhesive absorbing surface f of the tape connecting assembly 32, and the adhesive tape e needs to be loosened, the first clamping driving member 426 drives the first adsorption half roller 4211 away from the second adsorption half roller 4213, thereby loosening the adhesive tape e. At this time, the second clamping driving member 427 does not drive the second adsorption half roller 4213 to move, thereby preventing the second adsorption half roller 4213 from pressing against the adhesive absorbing surface f too much and damaging the adhesive tape e.

[0120] Furthermore, a first slide rail is provided on the first rotating seat 423, and the first slide 424 and the second slide 425 are both provided on the first slide rail, so that the first slide 424 can move along the first slide rail under the driving action of the first clamping driving member 426, and the second slide 425 can also move along the first slide rail under the driving action of the second clamping driving member 427, thereby respectively driving the first adsorption half roller 4211 and the second adsorption half roller 4213 to move closer to or away from each other. In this way, the first slide rail is used to guide the movement of the first slide 424 and the second slide 425, 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.

[0121] In some embodiments, the driving assembly 41 includes a driving unit 410, a third transfer seat 416, and an elastic buffer 419. The third transfer seat 416 is installed at the driving end of the driving unit 410, and the first mounting seat 418 is movably connected to the third transfer seat 416, so that the driving unit 410 can drive the first mounting seat 418 to move through the third transfer seat 416, and then the first mounting seat 418 drives the glue 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 glue suction roller 421. In this way, when the first mounting seat 418 drives the glue suction roller 421 to press against the glue suction surface f of the tape connecting assembly 32, the first mounting seat 418 can float relative to the third transfer seat 416 under the action of the pressing force and further compress the elastic buffer 419, thereby buffering the impact force between the glue suction roller 421 and the glue suction surface f, avoiding hard impact between the glue suction roller 421 and the glue suction surface f and damaging the tape e.

[0122] Similarly, when the first mounting seat 418 drives the glue suction roller 421 to press against the spare material roll A1, under the action of the pressing force, the first mounting seat 418 can float relative to the third transfer seat 416 and further compress the elastic buffer 419, thereby buffering the impact force between the glue suction roller 421 and the spare material roll A1, avoiding hard impact between the glue suction roller 421 and the spare material roll A1 and crushing the tape e or the spare material roll A1.

[0123] It should be noted that the elastic buffer 419 can be an elastic device capable of generating a buffer force, such as a cylinder or a spring. In the embodiment where the elastic buffer 419 is an air cylinder, since the buffer force output by the air cylinder can be kept constant and does not increase with the increase of the compression amount, it is possible to ensure that the contact force between the adhesive suction roller 421 and the adhesive suction surface f or the spare material roll A1 remains constant, thereby preventing the contact force from being too large or too small.

[0124] Specifically in the embodiment, the driving unit 410 includes a translation driving member 411 (see Figure 1), 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 installed at the driving end of the translation driving member 411, so that the translation driving member 411 can drive the first driving member 412 to move along the first direction X1. The first transfer seat 413 is installed at the driving end of the first driving member 412, so that the first driving member 412 can drive the first transfer seat 413 to move along the third direction X3. The second driving member 414 is installed on the first transfer seat 413, so that the second driving member 414 can move with the first transfer seat 413. The second transfer seat 415 is movably connected to the first transfer seat 413 along the second direction X2, and is connected to the driving end of the second driving member 414, so that the second driving member 414 can drive the second transfer seat 415 to move relative to the first transfer seat 413 along the second direction X2. The third driving member 417 is mounted on the second transfer seat 415, so that the third driving member 417 can move with the second transfer seat 415. The third transfer seat 416 is movably connected to the second transfer seat 415 along the third direction X3, and is connected to the driving end of the third driving member 417, so that the third driving member 417 can drive the third transfer seat 416 to move relative to the second transfer seat 415 along the third direction X3. The first mounting seat 418 is movably connected to the third transfer seat 416 along the second direction X2, so that the first mounting seat 418 can move with the third transfer seat 416, thereby driving the glue suction roller 421 to move with the third transfer seat 416.

[0125] In this way, the glue suction roller 421 is driven to move along the first direction X1 by the translation drive 411, the glue suction roller 421 is driven to move along the third direction X3 by the first drive 412, the glue suction roller 421 is driven to move along the second direction X2 by the second drive 414, the glue suction roller 421 is driven to move along the third direction X3 by the third drive 417, and the glue suction roller 421 is driven to rotate around its own axis by the first rotation drive 422, so that the glue suction roller 421 can accurately complete the transfer of the adhesive tape e, use the adhesive tape e to stick the starting end A3 of the material tape on the spare material roll A1, and pull the spare material tape A2 through the tape splicing component 32 and the waste material collecting component 33 in sequence. It should be noted that the translation drive 411, the first drive 412, the second drive 414 and the third drive 417 can adopt linear drive modules such as cylinders, electric cylinders, and synchronous belt drive mechanisms, as long as the accurate movement of the glue suction roller 421 can be achieved, and no limitation is made here.

[0126] Furthermore, the first transfer seat 413 is provided with a second slide rail extending longitudinally along the second direction X2. The second transfer seat 415 is slidably provided on the second slide rail, so that the second slide rail is used to guide the movement of the second transfer seat 415 relative to the first transfer seat 413 along the second direction X2.

[0127] Furthermore, the second transfer seat 415 is provided with a third slide rail, which extends longitudinally along the third direction X3. The third transfer seat 416 is slidably provided on the third slide rail, so that the third slide rail is used to guide the movement of the third transfer seat 416 relative to the second transfer seat 415 along the third direction X3.

[0128] Furthermore, a fourth slide rail is disposed on the third transfer seat 416 and extends longitudinally along the second direction X2. The first mounting seat 418 is slidably disposed on the fourth slide rail, so that the fourth slide rail is used to guide the movement of the first mounting seat 418 relative to the third transfer seat 416 along the second direction X2.

[0129] Please see again Figure 2 and Figure 3 In an embodiment of the present application, the glue preparation mechanism 10 includes a mounting substrate 16 and a tape unwinding assembly 11 and a cutting assembly 12 both mounted on the mounting substrate 16. The tape unwinding assembly 11 is used to unwind and output the tape e to the cutting assembly 12. The driving assembly 41 can drive the glue taking assembly 42 to move to the downstream of the cutting assembly 12, so that the glue suction roller 421 of the glue taking assembly 42 clamps and fixes the starting end of the tape e. After the glue suction roller 421 clamps and fixes the starting end of the tape e, the glue suction roller 421 rotates around its own axis, thereby winding the tape e onto the glue suction roller 421. After a certain length of the tape e is wound on the glue suction roller 421, the cutting assembly 12 cuts off the tape e passing by, thereby enabling the glue suction roller 421 to pick up a certain length of the tape e.

[0130] Specifically in the embodiment, the glue preparation mechanism 10 also includes a first clamping assembly 13 and a second clamping assembly 14, both of which are mounted on the mounting substrate 16. The first clamping assembly 13 is located on the upstream side of the cutting assembly 12, and is used to clamp or loosen the adhesive tape e passing through. The second clamping assembly 14 is located on the downstream side of the cutting assembly 12, and is used to clamp or loosen the adhesive tape e passing through. In this way, during the process of the adhesive suction roller 421 clamping the starting end of the fixed adhesive tape e and winding the adhesive tape e, the first clamping assembly 13 and the second clamping assembly 14 both maintain the state of loosening the adhesive tape e, so that the adhesive tape e can be transported downstream and wound on the adhesive suction roller 421 under the traction of the adhesive suction roller 421. After the adhesive suction roller 421 winds a certain length of the 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 adhesive tape e passing through. Then, the cutting assembly 12 cuts off the adhesive tape e passing through, so that the adhesive suction roller 421 can carry the adhesive tape e wound thereon and move toward the tape splicing assembly 32 or the spare material roll A1 on the unwinding mechanism 31 .

[0131] 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 16, and the cutter is mounted on the driving end of the cutting drive, so that the cutting drive can drive the cutter to perform a cutting action, thereby cutting off the passing tape e through the cutter. Optionally, the cutting drive can be a cylinder.

[0132] Specifically, the first clamping assembly 13 includes a first clamping driver (not shown) and two first clamping blocks (not shown). The first clamping driver is mounted on the mounting substrate 16, and the two first clamping blocks are respectively mounted on the two driving ends of the first clamping driver, and the two first clamping blocks are spaced to form a first clamping channel for the tape e to pass through. The first clamping driver is used to drive the two first clamping blocks to clamp or release the tape e therebetween. Optionally, the first clamping driver can be a clamping claw cylinder.

[0133] Specifically, the second clamping assembly 14 includes a second clamping driver (not shown) and two second clamping blocks (not shown). The second clamping driver is mounted on the mounting substrate 16, and the two second clamping blocks are respectively mounted on the two driving ends of the second clamping driver, and the two second clamping blocks are spaced to form a second clamping channel for the tape e to pass through. The second clamping driver is used to drive the two second clamping blocks to clamp or release the tape e therebetween. Optionally, the second clamping driver can be a clamping claw cylinder.

[0134] Furthermore, the glue preparation mechanism 10 also includes a cache component 15 installed on the mounting substrate 16. The cache component 15 is located between the cutting component 12 and the tape unwinding component 11, and is used to cache the passing tape e. In this way, the cache component 15 is used to cache the tape e, so that in the process of the glue suction roller 421 winding the tape e, the cache component 15 releases the tape e (that is, the amount of the cached tape e is reduced), and the tape e released by the cache component 15 is finally wound onto the glue suction roller 421, thereby preventing the glue suction roller 421 from directly pulling the tape e from the tape unwinding component 11 when winding the tape e, thereby preventing the tape e from being broken due to excessive tension.

[0135] Specifically, the buffer assembly 15 includes a fixed roller 151 and a movable roller 152 disposed on the mounting substrate 16. The position of the fixed roller 151 relative to the mounting substrate 16 is fixed and unchanged, and the movable roller 152 can be moved closer to or away from the fixed roller 151 under the action of an external force. In this way, when the adhesive suction roller 421 winds the adhesive tape e, the adhesive tape e drives the movable roller 152 to move closer to the fixed roller 151, so that the length of the adhesive tape e cached between the movable roller 152 and the fixed roller 151 is reduced. When the adhesive suction roller 421 stops winding the adhesive tape e, the movable roller 152 moves away from the fixed roller 151 and resets, so that the length of the adhesive tape e cached between the movable roller 152 and the fixed roller 151 is increased.

[0136] Furthermore, the cache assembly 15 also includes a movable block 153 and a cache driver 154. The movable block 153 is movably connected to the mounting substrate 16, and the movable roller 152 is mounted on the movable block 153, so that the movable roller 152 can move relative to the mounting substrate 16 with the movable block 153, thereby approaching or moving away from the fixed roller 151. The cache driver 154 is mounted on the mounting substrate 16, and the cache driver 154 is used to provide a driving force that enables the movable block 152 to drive the movable roller 152 to move away from the fixed roller 151. In this way, when the adhesive suction roller 421 winds the adhesive tape e, the adhesive tape e drives the movable block 153 and the movable roller 152 to approach the fixed roller 151, so that the length of the adhesive tape e cached between the movable roller 152 and the fixed roller 151 is reduced. When the adhesive suction roller 421 stops winding the adhesive tape e, the movable block 153 drives the movable roller 152 to move away from the fixed roller 151 and reset under the driving action of the buffer drive 154, so that the length of the adhesive tape e buffered between the movable roller 152 and the fixed roller 151 increases. Optionally, the buffer drive 154 can be a cylinder.

[0137] Furthermore, a fifth slide rail (not shown) is provided on the mounting substrate 16 , and the movable block 153 is slidably disposed on the fifth slide rail, so that the fifth slide rail is used to guide the movement of the movable block 153 relative to the mounting substrate 16 .

[0138] See also Figure 1 In the embodiment of the present application, the roll changing device further comprises a material preparation mechanism 20, and the transfer mechanism 40 further comprises a material taking component 43 installed on the driving end of the driving component 41. The material preparation mechanism 20 is used to provide a spare material roll A1 (see Figure 6), the driving component 41 is also used to drive the material picking component 43 to move between the material preparation mechanism 20 and the unwinding mechanism 31. When the driving component 41 drives the material picking component 43 to move to the material preparation mechanism 20, the material picking component 43 can pick up the spare material roll A1 provided by the material preparation mechanism 20. When the driving component 41 drives the material picking component 43 to move to the unwinding mechanism 31, the material picking component 43 can release the picked-up spare material roll A1 to the unwinding mechanism 31, that is, the material picking component 43 can realize the transfer of the spare material roll A1 provided by the material preparation mechanism 20 to the unwinding mechanism 31. In this way, compared with the manual loading method in the prior art, the material picking component 43 is used in this embodiment to realize automatic loading, which is conducive to improving the degree of automation, reducing labor costs, and improving production efficiency.

[0139] It should be noted that, in the present embodiment, the driving assembly 41 is used to drive the glue taking assembly 42 and the material taking assembly 43 to move, that is, the glue taking assembly 42 and the material taking assembly 43 share the same driving assembly 41, which is conducive to simplifying the structure and reducing the equipment cost. Of course, in other embodiments, the material taking assembly 43 may not be installed on the driving end of the driving assembly 41, but a driving component is separately configured for the material taking assembly 43, and the driving component is used to drive the material taking assembly 43 to move, as long as the material taking assembly 43 can be driven to complete the transfer of the spare material roll A1 between the material preparation mechanism 20 and the unwinding mechanism 31, and no limitation is made here. For ease of understanding, this article takes the implementation method of using the driving assembly 41 to drive the glue taking assembly 42 and the material taking assembly 43 to move as an example for explanation.

[0140] See also Figures 15 to 17 and Fig. 20 The material preparation mechanism 20 includes a support seat 21, a material storage shaft 22 and a material pushing assembly 23. The two axial ends of the material storage shaft 22 are respectively a mounting end a1 and a material inlet and outlet end a2. The mounting end a1 of the material storage shaft 22 is mounted on the support seat 21, and the material storage shaft 22 is used to mount at least one spare material roll A1 along the axial direction. The material taking assembly 43 has a material taking shaft 431 (see Fig.18), the driving assembly 41 can drive the material taking assembly 43 to move to the material preparation mechanism 20, so that the material taking shaft 431 of the material taking assembly 43 is axially docked with the feed-in and discharge end a2 of the material storage shaft 22 of the material preparation mechanism 20. The pushing assembly 23 is installed on the support seat 21, and is used to push the spare material roll A1 on the material storage shaft 22 to move to the material taking shaft 431 through the feed-in and discharge end a2 of the material storage shaft 22. In this way, in actual use, first, the driving assembly 41 drives the material taking assembly 43 to move to the material preparation mechanism 20, so that the material taking shaft 431 of the material taking assembly 43 is axially docked with the feed-in and discharge end a2 of the material storage shaft 22 of the material preparation mechanism 20. Then, the pushing assembly 23 pushes each spare material roll A1 on the material storage shaft 22 to move toward the feed-in and discharge end a2 of the material storage shaft 22, until a spare material roll A1 closest to the feed-in and discharge end a2 of the material storage shaft 22 passes through the feed-in and discharge end a2 and moves to the material taking shaft 431. Then, the driving assembly 41 drives the material taking assembly 43 to move toward the unwinding mechanism 31 , so as to transfer the spare material roll A1 on the material taking shaft 431 to the unwinding mechanism 31 .

[0141] In some embodiments, the push assembly 23 includes a push drive 231, a telescopic unit 233 and a push block 232. The push drive 231 is mounted on the support seat 21, and the push block 232 is disposed on the storage shaft 22. The telescopic unit 233 is connected between the push drive 231 and the push block 232. The push drive 231 is used to drive the telescopic unit 233 to telescope, so as to drive the push block 232 to move along the storage shaft 22, thereby pushing each spare roll A1 on the storage shaft 22 to move toward the inlet and outlet end a2 of the storage shaft 22.

[0142] Further, the telescopic unit 233 includes a first mobile seat 2331, a connecting rod telescopic frame 2336, a second mobile seat 2333 and a second mounting seat 2335. The first mobile seat 2331 is installed at the driving end of the push drive member 231, and the push drive member 231 is used to drive the first mobile seat 2331 to move along the first direction X1. The second mobile seat 2333 is movably connected to the second mounting seat 2335, and the push block 232 is installed on the second mobile seat 2333. The connecting rod telescopic frame 2336 is hingedly connected between the first mobile seat 2331 and the second mobile seat 2333, and is used to convert the movement of the first mobile seat 2331 along the first direction X1 into the movement of the push block 232 along the third direction X3. The third direction X3 is consistent with the axial direction of the storage shaft 22. In this way, when pushing material is needed, the pushing drive 231 drives the first movable seat 2331 to move along the first direction X1, so as to drive 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 to the feed and discharge end a2 of the storage shaft 22.

[0143] It should be noted that the use of the connecting rod telescopic frame 2336 for transmission is beneficial to converting the smaller stroke output by the push drive 231 into a larger stroke of the push block 232. On the one hand, it is beneficial to reduce the specifications of the push drive 231 and reduce equipment costs; on the other hand, it makes the structure more compact and reduces the required space, especially reduces the axial space occupied by the storage shaft 22, thereby improving space utilization.

[0144] Specifically, the connecting rod telescopic frame 2336 includes a plurality of first connecting rods b1 arranged in parallel and at intervals, and a plurality of second connecting rods b2 arranged in parallel and at intervals. Each first connecting rod b1 is cross-arranged in one-to-one correspondence with each second connecting rod b2. Each first connecting rod b1 is hinged with a corresponding second connecting rod b2 at the intersection, and the end of each first connecting rod b1 is hinged with the end of the adjacent second connecting rod b2.

[0145] 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 one end of the connecting rod telescopic frame 2336 close to the first movable seat 2331: one of the end of the first connecting rod b1 and the end of 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 one end of the connecting rod telescopic frame 2336 close to the second movable seat 2333: one of the end of the first connecting rod b1 and the end of the second connecting rod b2 is hinged to the second movable seat 2333, and the other is hinged to the second fixed seat 2334.

[0146] In this way, when the push drive member 231 drives the first movable seat 2331 to move close to the first fixed seat 2332, the crossing angle θ of each set of the first connecting rods b1 and the second connecting rods b2 can be driven to gradually decrease, so that the connecting rod telescopic frame 2336 is extended along the axial direction of the material storage shaft 22, thereby driving the second mounting seat 2335 and the pusher block 232 to move toward the material inlet and outlet end a2 along the axial direction of the material storage shaft 22. The connecting rod telescopic frame 2336 drives the second movable seat 2333 to gradually move close to the second fixed seat 2334 during the extension process.

[0147] When the push drive 231 drives the first movable seat 2331 to move away from the first fixed seat 2332, the crossing angle θ of each set of the first connecting rods b1 and the second connecting rods b2 can be gradually increased, so that the connecting rod telescopic frame 2336 shrinks along the axial direction of the material storage shaft 22, thereby driving the second mounting seat 2335 and the pusher block 232 to move toward the mounting end a1 along the axial direction of the material storage shaft 22. The connecting rod telescopic frame 2336 drives the second movable seat 2333 to gradually move away from the second fixed seat 2334 during the shrinking process.

[0148] Specifically in the embodiment, the pusher assembly 23 also includes a first support roller 234 that is rollably connected to the pusher block 232. The pusher block 232 is supported on the storage shaft 22 through the first support roller 234, so that when the connecting rod telescopic frame 2336 drives the pusher block 232 to move along the axial direction of the storage shaft 22, the first support roller 234 rolls on the storage shaft 22, which is conducive to reducing the thrust required to push each spare material roll A1 along the axial direction of the storage shaft 22, thereby reducing the difficulty of pushing.

[0149] It should be noted that the number of the first support rollers 234 can be one, two or more. When there is one first support roller 234, the pusher block 232 is supported on the storage shaft 22 by the one first support roller 234. When there are multiple first support rollers 234, the pusher block 232 is supported on the storage shaft 22 by each of the first support rollers 234. The number of the first support rollers 234 can be set according to the size of the storage shaft 22, as long as the friction force generated by the pusher block 232 moving along the axial direction of the storage shaft 22 can be reduced, and is not limited here.

[0150] Specifically in the embodiment, the material preparation mechanism 20 further includes a plurality of second support rollers (not shown) that are rollably connected to the material storage shaft 22. The plurality of second support rollers are arranged at intervals along the axial direction of the material storage shaft 22, and the spare material roll A1 is supported on the material storage shaft 22 by the corresponding second support rollers. In this way, when the pushing block 232 pushes each spare material roll A1, each spare material roll A1 moves along the axial direction of the material storage shaft 22 under the rolling action of the corresponding second support roller, which greatly reduces the thrust required to push each spare material roll A1 along the axial direction of the material storage shaft 22, and further reduces the difficulty of pushing the material.

[0151] See also Fig.18 , Fig.19 and Fig.21In the embodiment of the present application, the unwinding mechanism 31 has an unwinding shaft 311 for loading the spare material roll A1. The material picking assembly 43 includes the above-mentioned material picking shaft 431, a bearing seat 432 and a feeding unit 435. The bearing seat 432 is installed at the driving end of the translation drive member 411, so that the translation drive member 411 can drive the bearing seat 432 to move along the first direction X1. The material picking shaft 431 and the feeding unit 435 are both installed on the bearing seat 432, so that the material picking shaft 431 and the feeding unit 435 can move together with the bearing seat 432. Under the driving action of the translation drive member 411, the bearing seat 432 can drive the material picking shaft 431 to move along the first direction X1 to axially dock with the storage shaft 22, so that the pushing assembly 23 pushes the spare material roll A1 on the storage shaft 22 to the material picking shaft 431. Under the driving action of the translation drive member 411, the bearing seat 432 can also drive the material taking shaft 431 to move to axially dock with the unwinding shaft 311. At this time, the feeding unit 435 can controllably push the spare material roll A1 on the material taking shaft 431 axially to the unwinding shaft 311, thereby realizing the transfer of the spare material roll A1 from the material storage shaft 22 to the unwinding shaft 311.

[0152] Specifically in the embodiment, the material taking assembly 43 also includes a third mounting seat 433 and a fourth driving member 434. The third mounting seat 433 is movably connected to the bearing seat 432 along the third direction X3. The fourth driving member 434 is installed on the bearing seat 432, and the driving end of the fourth driving member 434 is connected to the third mounting seat 433, so that the fourth driving member 434 can drive the third mounting seat 433 to move relative to the bearing seat 432 along the third direction X3. The material taking shaft 431 is installed on the third mounting seat 433, so that the material taking shaft 431 can move with the third mounting seat 433. The axial direction of the material taking shaft 431 is consistent with the third direction X3.

[0153] The translation drive member 411 of the driving assembly 41 is used to drive the bearing seat 432 to move along the first direction X1, thereby driving the material picking shaft 431 to move along the first direction X1, so that the material picking shaft 431 moves along the first direction X1 to be opposite to the material storage shaft 22 or the unwinding shaft 311 in the third direction X3. The fourth driving member 434 is used to drive the third mounting seat 433 to move along the third direction X3, thereby driving the material picking shaft 431 to move along the third direction X3, so that the material picking shaft 431 moves along the third direction X3 to axially dock or separate from the material storage shaft 22 or the unwinding shaft 311.

[0154] It should be noted that the material roll (i.e., the working material roll or the spare material roll A1) includes a barrel A5 and a material tape wound on the barrel 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 unwinds the working material tape downstream. When the working material roll on the unwinding shaft 311 is unwound, the tape connecting assembly 32 cuts off the passing working material tape and the spare material tape A2. The unwinding shaft 311 of the unwinding mechanism 31 drives the barrel A5 thereon to rotate in the opposite direction until the upstream cut end of the working material tape is wound onto the barrel A5. At this time, the barrel A5 on the unwinding shaft 311 needs to be removed from the unwinding shaft 311 and transferred to a designated position.

[0155] In order to unload the barrel A5 on the unwinding shaft 311, in some embodiments, the translation drive member 411 of the drive assembly 41 can drive the bearing seat 432 to move along the first direction X1 to the unwinding shaft 311, so that the material picking shaft 431 and the unwinding shaft 311 are opposite to each other in the third direction X3. The fourth drive member 434 can drive the third mounting seat 433 to move along the third direction X3, thereby driving the material picking shaft 431 to axially dock with the unwinding shaft 311. The feeding unit 435 can controllably clamp the barrel A5 on the unwinding shaft 311, and drive the barrel A5 to move to the material picking shaft 431 along the axial direction, thereby realizing the transfer of the barrel A5 from the unwinding shaft 311 to the material picking shaft 431.

[0156] It should be noted that in this embodiment, the feeding unit 435 is used to push the spare material roll A1 on the material taking shaft 431 to the unwinding shaft 311 along the third direction X3, and the feeding unit 435 is used to clamp the barrel A5 on the unwinding shaft 311, and drive the barrel A5 to move along the third direction X3 to the material taking shaft 431. Compared with the solution of pushing the barrel A5 on the unwinding shaft 311 to transfer to the material taking shaft 431, the method of clamping the barrel A5 by the feeding unit 435 in this embodiment can reduce the stroke of the feeding unit 435, which is conducive to saving space, especially saving space in the third direction X3.

[0157] It should be noted that the barrel A5 on the unwinding shaft 311 is not limited to being transferred to the material taking shaft 431 by the feeding unit 435. In other embodiments, the barrel A5 on the unwinding shaft 311 may be clamped by the feeding unit 435 and driven axially to separate the barrel A5 from the unwinding shaft 311. The barrel A5 is not sleeved on the material taking shaft 431, but is clamped and fixed by the feeding unit 435. For ease of understanding, this article takes the embodiment in which the feeding unit 435 transfers the barrel A5 on the unwinding shaft 311 to the material taking shaft 431 as an example for description.

[0158] Specifically in the embodiment, the feeding unit 435 includes a fifth driving member 4351, a fourth mounting seat 4352 and a clamping portion 4353. The fifth driving member 4351 is mounted on the bearing seat 432, so that the fifth driving member 4351 can move with the bearing seat 432. The fourth mounting seat 4352 is mounted on the driving end of the fifth driving member 4351, and the fifth driving member 4351 is used to drive the fourth mounting seat 4352 to move along the third direction X3. The clamping portion 4353 is mounted on the fourth mounting seat 4352, so that the clamping portion 4353 can move with the fourth mounting seat 4352. It should be noted that the fifth driving member 4351 can adopt a linear drive module such as an electric cylinder or a pneumatic cylinder, which is not limited here.

[0159] In this way, when it is necessary to push the spare material roll A1 on the material picking shaft 431 onto the unwinding shaft 311, the clamping portion 4353 is located at the end of the spare material roll A1 away from the unwinding shaft 311, and the fifth driving member 4351 drives the fourth mounting seat 4352 to move along the third direction X3, thereby driving the clamping portion 4353 to push the spare material roll A1 on the material picking shaft 431 along the third direction X3 to move toward the unwinding shaft 311 until the spare material roll A1 is pushed onto the unwinding shaft 311.

[0160] When it is necessary to push the barrel A5 on the unwinding shaft 311 onto the material taking shaft 431, the fifth driving member 4351 drives the fourth mounting seat 4352 to move along the third direction X3 close to the unwinding shaft 311, thereby driving the clamping portion 4353 to move along the third direction X3 to the barrel A5 on the unwinding shaft 311. Then, the clamping portion 4353 clamps the barrel A5 on the unwinding shaft 311. Then, the fifth driving member 4351 drives the fourth mounting seat 4352 to move along the third direction X3 close to the material taking shaft 431, thereby driving the clamping portion 4353 to move along the third direction X3 to the material taking shaft 431. Since the clamping portion 4353 clamps the barrel A5, the barrel A5 also follows the clamping portion 4353 to move from the unwinding shaft 311 to the material taking shaft 431.

[0161] Specifically, the clamping part 4353 includes a clamping claw driving member c1 and two clamping claws c2. The clamping claw driving member c1 is installed on the fourth mounting seat 4352, so that the clamping claw driving member c1 can move with the fourth mounting seat 4352. The two clamping claws c2 are respectively installed at the two driving ends of the clamping claw driving member c1, and the two clamping claws c2 are spaced to form a clamping space for the material taking shaft 431 or the unwinding shaft 311 to pass through. The clamping claw driving member c1 is used to drive the two clamping claws c2 to clamp or release the barrel A5 on the unwinding shaft 311. Optionally, the clamping claw driving member c1 can adopt a clamping claw cylinder.

[0162] In this way, when the spare roll A1 on the material-taking shaft 431 needs to be pushed onto the unwinding shaft 311, the two clamping claws c2 are located at one end of the spare roll A1 away from the unwinding shaft 311, and the clamping claw driving member c1 drives the two clamping claws c2 to approach each other, so that the two clamping claws c2 can abut against the end of the spare roll A1. Then, the fifth driving member 4351 drives the fourth mounting seat 4352 to move along the third direction X3 close to the unwinding shaft 311, thereby driving the two clamping claws c2 to push the spare roll A1 on the material-taking shaft 431 toward the unwinding shaft 311 along the third direction X3 until the spare roll A1 is pushed onto the unwinding shaft 311.

[0163] When it is necessary to push the barrel A5 on the unwinding shaft 311 onto the material taking shaft 431, the clamping jaw driving member c1 drives the two clamping jaws c2 to move away from each other, so that the clamping space between the two clamping jaws c2 is wide enough for the barrel A5 on the unwinding shaft 311 to enter. Then, the fifth driving member 4351 drives the fourth mounting seat 4352 to move along the third direction X3 close to the unwinding shaft 311, thereby driving the two clamping jaws c2 to move along the third direction X3 to the barrel A5 on the unwinding shaft 311. At this time, the barrel A5 on the unwinding shaft 311 is located between the two clamping jaws c2. Then, the clamping jaw driving member c1 controls the two clamping jaws c2 to move closer to each other until the barrel A5 on the unwinding shaft 311 is clamped. Then, the fifth driving member 4351 drives the fourth mounting seat 4352 to move along the third direction X3 close to the material picking shaft 431, thereby driving the two clamping jaws c2 to move along the third direction X3 to the material picking shaft 431. Since the two clamping jaws c2 clamp the material barrel A5, the material barrel A5 also follows the two clamping jaws c2 to move from the unwinding shaft 311 to the material picking shaft 431.

[0164] See also Figure 1 , Fig.23 and Fig.24In an embodiment of the present application, the roll changing device further includes a discharge mechanism 60, which includes a guide 61 and a storage member 62. The longitudinal ends of the guide 61 are a feed end d1 and a connection end d2, respectively. The guide 61 is docked with the storage member 62 through the connection end d2. Under the driving action of the translation drive member 411 of the drive assembly 41, the bearing seat 432 can drive the material collection shaft 431 to move to the feed end d1. The feeding unit 435 can controllably push the barrel A5 on the material collection shaft 431 away from the material collection shaft 431 in the axial direction and drop it into the feed end d1 of the guide 61. The guide 61 is constructed to guide the barrel A5 at the feed end d1 to roll toward the connection end d2 and reach the storage member 62. Thus, after the barrel A5 is transferred from the unwinding shaft 311 to the material taking shaft 431, first, the translation driving member 411 drives the bearing seat 432 to move toward the guide member 61 along the first direction X1 until the material taking shaft 431 reaches above the feeding end d1 of the guide member 61. Then, the fifth driving member 4351 drives the fourth mounting seat 4352 to move along the third direction X3, thereby driving the two clamping claws c2 to push the barrel A5 away from the material taking shaft 431 along the third direction X3, so that the barrel A5 falls into the feeding end d1 of the guide member 61. The barrel A5 that falls into the feeding end d1 of the guide member 61 rolls along the guide member 61 toward the connecting end d2 until the barrel A5 reaches the storage member 62 for storage.

[0165] Specifically in the embodiment, the guide member 61 has a guide groove 612 extending longitudinally from the feeding end d1 to the connecting end d2. The guide groove 612 is used to receive the barrel A5 and guide the barrel A5 to roll from the feeding end d1 to the connecting end d2. In this way, the guide groove 612 is used to receive the barrel A5 and guide it into the storage member 62, effectively reducing the risk of the barrel A5 falling from the guide member 61.

[0166] Further, the storage member 62 has a storage trough 622 for accommodating the barrel A5. The unloading mechanism 60 also includes a seventh driving member 641 and a push block 642. The push block 642 is installed at the driving end of the seventh driving member 641 and is located at one end of the storage member 62 close to the guide member 61. Under the driving action of the seventh driving member 641, the push block 642 can push the barrel A5 in the storage trough 622 to move toward the end away from the guide member 61. In this way, when the barrel A5 rolls from the guide groove 612 on the guide member 61 to the storage trough 622 of the storage member 62, the seventh driving member 641 drives the push block 642 to move along the storage trough 622, thereby pushing the barrel A5 in the storage trough 622 toward the end of the storage trough 622 away from the guide member 61. When the barrel A5 in the storage trough 622 is full, the barrel A5 in the storage trough 622 can be transferred manually or by handling equipment. Optionally, the seventh driving member 641 may be a cylinder.

[0167] It should be noted that in order to shorten the stroke of the material picking component 43, in some embodiments, the unloading mechanism 60 is arranged as close to the material preparation mechanism 20 as possible, so that the position where the material picking shaft 431 of the material picking component 43 unloads the barrel A5 at the unloading mechanism 60 is close to or the same position as the position where the material picking shaft 431 of the material picking component 43 transfers the spare material roll A1 at the material preparation mechanism 20, which greatly shortens the stroke of the material picking component 43, makes the roll changing device structure more compact, and improves space utilization.

[0168] Since the unloading mechanism 60 is close to the material preparation mechanism 20, when the material taking assembly 43 moves to the material preparation mechanism 20 to transfer the spare material belt A2, the feed end d1 of the guide 61 is easy to interfere with the material taking assembly 43. In order to avoid the interference between the feed end d1 of the guide 61 and the material taking assembly 43, in some embodiments, the guide 61 is constructed to be able to rotate around its own connection end d2 to the material receiving position and the avoidance position. When the guide 61 rotates to the material receiving position, the feed end d1 can receive the barrel A5 pushed away from the material taking shaft 431 by the feeding unit 435. When the guide 61 rotates to the avoidance position, the feed end d1 allows the material taking shaft 431 of the material taking assembly 43 to axially dock with the storage shaft 22, thereby avoiding the interference between the guide 61 and the material taking shaft 431 of the material taking assembly 43.

[0169] Further, the unloading mechanism 60 also includes a fifth mounting seat 65 and a sixth driving member 63. The material storage member 62 is fixedly connected to the fifth mounting seat 65. The connecting end d2 of the guide member 61 is rotatably connected to the fifth mounting seat 65. The sixth driving member 63 includes a driving member body 631 and a telescopic end 632 that can be extended or retracted relative to the driving member body 631 in a controlled manner. The driving member body 631 is hingedly mounted on the fifth mounting seat 65, and the telescopic end 632 is hingedly connected to the guide member 61, so that the guide member 61 is driven to rotate between the material receiving position and the avoidance position by the telescopic end 632 being telescopic relative to the driving member body 631. Optionally, the sixth driving member 63 can be a cylinder.

[0170] Optionally, when the telescopic end 632 is extended relative to the driving member body 631, it can drive the guide member 61 to rotate to the avoidance position, so that the material collection shaft 431 of the material collection component 43 can smoothly transfer the spare material roll A1 at the material preparation mechanism 20. When the telescopic end 632 is retracted relative to the driving member body 631, it can drive the guide member 61 to rotate to the material receiving position, so that the barrel A5 on the material collection shaft 431 of the material collection component 43 can smoothly fall into the feeding end d1 of the guide member 61.

[0171] See also Figure 1 , Figure 7 , Fig. 9 and Fig.10 In the embodiment of the present application, the roll changing device also includes a device for receiving waste roll A4 (see Fig.10) of the waste box 50 (see Figure 1 ). The transfer mechanism 40 also includes a waste material taking component 44 installed at the driving end of the driving component 41. The driving component 41 is also used to drive the waste material taking component 44 to move to the receiving roller 331 of the waste material receiving component 33 and the waste box 50. When the driving component 41 drives the waste material taking component 44 to move to the receiving roller 331 of the waste material receiving component 33, the waste material taking component 44 can take away the waste material roll A4 on the receiving roller 331 of the waste material receiving component 33. When the driving component 41 drives the waste material taking component 44 to move to the waste box 50, the waste material taking component 44 can release the waste material roll A4 into the waste box 50. It should be noted that it is not limited to using the driving component 41 to drive the waste material taking component 44 to move. In other embodiments, a driving component can also be separately configured for the waste material taking component 44, and the driving component can be used to drive the waste material taking component 44 to move, as long as the waste material roll A4 can be transferred, which is not limited here.

[0172] Specifically, the waste collecting component 44 is installed on the second transfer seat 415 of the driving component 41, so that the waste collecting component 44 can move along the first direction X1 and the second direction X2 with the second transfer seat 415, ensuring that the waste collecting component 44 can accurately move to the waste receiving roller 331 of the waste receiving component 33 or the waste box 50.

[0173] Specifically in the embodiment, the waste material taking 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 the second transfer seat 415 to move with the second transfer seat 415. The first clamping block 4453 and the second clamping block 4455 are arranged on the second moving seat 443 to move with the second moving seat 443. The first clamping block 4453 and the second clamping block 4455 are spaced to form a receiving space j for the receiving roller 331 to enter. The first clamping block 4453 and the second clamping block 4455 are constructed to be controllably close to or away from each other to clamp or release the waste material roll A4. The sides of the first clamping block 4453 and the second clamping block 4455 facing each other are both provided with a supporting portion 4459 and a pushing portion 4457. The second moving seat 443 is configured to be controllably movable along the axial direction of the receiving roller 331, so as to drive each pushing portion 4457 to push the waste roll A4 on the receiving roller 331 to move along the axial direction and detach from the receiving roller 331, and then enter the receiving space j. Each supporting portion 4459 is used to support the waste roll A4 detached from the receiving roller 331 and located in the receiving space j.

[0174] Thus, when it is necessary to take away the waste roll A4 on the receiving roller 331, first, the third transfer seat 416 drives the second moving seat 443 to move to the waste taking position along the first direction X1 and / or the second direction X2, so that the receiving roller 331 of the waste receiving assembly 33 and the receiving space j between the first clamp block 4453 and the second clamp block 4455 are opposite in the third direction X3. Then, the second moving seat 443 drives the first clamp block 4453 and the second clamp block 4455 to move close to the receiving roller 331 along the third direction X3, so that the receiving roller 331 and the waste roll A4 thereon enter into the receiving space j between the first clamp block 4453 and the second clamp block 4455, until the pushing portion 4457 on the first clamp block 4453 and the pushing portion 4457 on the second clamp block 4455 reach the end of the waste roll A4 away from the second moving seat 443. Then, the first clamp 4453 and the second clamp 4455 are controlled to approach each other until the pusher 4457 on the first clamp 4453 and the pusher 4457 on the second clamp 4455 can abut against the end surface of the waste roll A4 away from the second moving seat 443. Then, the second moving seat 443 moves away from the receiving roller 331 along the third direction X3, thereby driving the pusher 4457 to push the waste roll A4 on the receiving roller 331 to move axially until the waste roll A4 is separated from the receiving roller 331 and is supported by each support part 4459 between the first clamp 4453 and the second clamp 4455. Then, the first clamp 4453 and the second clamp 4455 continue to approach each other to clamp the waste roll A4, thereby preventing the waste roll A4 from loosening. Then, the third transfer seat 416 drives the second moving seat 443 to move to the waste placement position along the first direction X1 and / or the second direction X2, so that the first clamping block 4453 and the second clamping block 4455 are located 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.

[0175] Furthermore, the first clamping block 4453 is provided with a plurality of supporting portions 4459, and the plurality of supporting portions 4459 on the first clamping block 4453 are arranged at intervals along the axial direction of the receiving roller 331. The second clamping block 4455 is provided with a plurality of supporting portions 4459, and the plurality of supporting portions 4459 on the second clamping block 4455 are arranged at intervals along the axial direction of the receiving roller 331. In this way, the plurality of supporting portions 4459 on the first clamping block 4453 and the plurality of supporting portions 4459 on the second clamping block 4455 are used to support the waste roll A4 entering the receiving space j, so as to prevent the waste roll A4 from falling.

[0176] Furthermore, in the arrangement direction of the first clamp 4453 and the second clamp 4455, the various support portions 4459 on the first clamp 4453 and the various support portions 4459 on the second clamp 4455 are staggered, so that when the first clamp 4453 and the second clamp 4455 are close to each other to clamp the waste roll A4, collision between the support portions 4459 on the first clamp 4453 and the support portions 4459 on the second clamp 4455 is avoided.

[0177] It should be noted that the support portion 4459 on the first clamp block 4453 and the second clamp block 4455 is not necessary. In other embodiments, the support portion 4459 may not be provided on the first clamp block 4453 and the second clamp block 4455. The waste roll A4 that has separated from the receiving roller 331 and entered the receiving space j is directly clamped and fixed by the first clamp block 4453 and the second clamp block 4455. In other embodiments, the support portion 4459 is not provided on the first clamp block 4453 and the second clamp block 4455 either. The first clamp block 4453 and the second clamp block 4455 are arranged in the vertical direction, so that the waste roll A4 that has separated from the receiving roller 331 and entered the receiving space j is supported on the lower one of the first clamp block 4453 and the second clamp block 4455. For ease of understanding, this article takes the embodiment in which the support portion 4459 is provided on both the first clamp block 4453 and the second clamp block 4455 as an example for description.

[0178] Further, each pusher portion 4457 includes a second elastic member (not shown) and a pusher column (not marked), and mounting holes are provided on the sides facing each other of the first clamp block 4453 and the second clamp block 4455. Part of the pusher column is inserted into the corresponding mounting hole, and the other part is located in the space between the first clamp block 4453 and the second clamp block 4455, and the pusher column is movable along the axial direction of the mounting hole. The second elastic member is arranged in the corresponding mounting hole and abuts against the part of the pusher column located in the mounting hole to provide a preload force that makes the pusher column have a movement tendency to move out of the mounting hole. In this way, when the first clamp block 4453 and the second clamp block 4455 approach each other and clamp the waste roll A4, even if the pusher column on the first clamp block 4453 and the pusher column on the second clamp block 4455 abut against each other, since the second elastic member is elastic, it will not cause damage, and will not interfere with the clamping action of the first clamp block 4453 and the second clamp block 4455. Similarly, when the first clamping block 4453 and the second clamping block 4455 are close to each other and clamp the waste roll A4, even if the material pushing post on the first clamping block 4453 abuts against the second clamping block 4455, or even if the material pushing post on the second clamping block 4455 abuts against the first clamping block 4453, since the second elastic member is elastic, it will not cause damage, and will not interfere with the clamping action of the first clamping block 4453 and the second clamping block 4455. Optionally, the material pushing portion 4457 can use a spring plunger, which is a standard part, which is conducive to reducing equipment costs.

[0179] Specifically in the embodiment, the waste material taking assembly 44 also includes a sixth mounting seat 441 and an eighth driving member 442. The sixth mounting seat 441 is mounted on the driving end of the driving assembly 41 so that the driving assembly 41 can drive the sixth mounting seat 441 to move along the first direction X1 and / or the second direction X2. The second moving seat 443 is movably connected to the sixth mounting seat 441 along the third direction X3. The eighth driving member 442 is mounted on the sixth mounting seat 441, and the driving end of the eighth driving member 442 is connected to the second moving seat 443, so that the eighth driving member 442 can drive the second moving seat 443 to move relative to the sixth mounting seat 441 along the third direction X3. Among them, the third direction X3 is consistent with the axial direction of the receiving roller 331.
