Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of battery manufacturing equipment, in particular to a glue preparation mechanism, a roll changing device and a winding device. BACKGROUND

[0002] In the process of battery manufacturing, the material belt on the material roll often needs to be continuously unwound and output to the downstream, for example, in the winding process of the battery cell, the pole piece needs to be continuously unwound and output to the winding device. When the working material belt on the working material roll is unwound, the working material belt needs to be cut off, and then the working material belt is connected with the standby material belt of the standby material roll, so as to continue to unwind and output the material belt to the downstream, that is, the roll changing is completed.

[0003] Since the working material belt and the standby material belt need to be bonded by using the adhesive tape, the glue preparation mechanism for providing the adhesive tape needs to be configured. In the prior art, the glue preparation mechanism includes a glue pulling mechanism and a glue suction plate. The glue pulling mechanism pulls the adhesive tape of a certain length to the glue suction plate. The glue suction plate adsorbs and fixes the adhesive tape thereon. Then, the pulled adhesive tape is cut off. Then, the adhesive tape on the glue suction plate is transferred to the specified position.

In the following description, a large number of specific details are set forth in order to fully understand the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application, and therefore the present application is not limited to the specific embodiments disclosed below.

[0053] ​​In the description of the present application, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate the orientation or positional relationship shown in the drawings, which are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation of the present application.

[0054] In addition, the terms "first", "second" are only for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined with "first", "second" can explicitly or implicitly include at least one of the features.

In contrast, when an element is referred to as being "directly on" or "directly connected to" another element, there are no intervening elements present. It will be understood that, although the terms "first", "second", etc. can be used herein to describe various elements, these elements should not be limited by these terms since such elements are commonly known by other terms.

[0058] Referring to Figures 1 to 4 The present application provides a roll changing device, which comprises a glue tape providing mechanism, a material roll providing mechanism 20, a roll out mechanism 31, a tape connecting mechanism 30 and a material roll taking mechanism 43.

[0059] The glue tape providing mechanism is used to provide glue tape e (see Figure 2 ) and transfer the glue tape e to the tape connecting mechanism 30, and the material roll providing mechanism 20 is used to provide a standby material roll A1 (see Figure 6 ). The material roll taking mechanism 43 is configured to be controllably moved to the material roll providing mechanism 20 and the roll out mechanism 31. When the material roll taking mechanism 43 is moved to the material roll providing mechanism 20, the standby material roll A1 provided by the material roll providing mechanism 20 can be picked up, and when the material roll taking mechanism 43 is moved to the roll out mechanism 31, the picked-up standby material roll A1 can be released to the roll out mechanism 31, that is, the material roll taking mechanism 43 can realize the transfer of the standby material roll A1 provided by the material roll providing mechanism 20 to the roll out mechanism 31.

[0060] The roll out mechanism 31 is used to load a working material roll and the standby material roll A1, and drive the working material roll thereon to output working material tape downstream. The tape connecting mechanism 30 is arranged downstream of the roll out mechanism 31, and is used to receive the glue tape e provided and transferred by the glue tape providing mechanism. The tape connecting mechanism 30 is also used to cut the working material tape when the working material roll on the roll out mechanism 31 is rolled out, and bond the downstream cut end of the working material tape with the standby material tape A2 of the standby material roll A1 by using the glue tape e, so as to realize the connection of the working material tape and the standby material tape A2, that is, realize the tape connection.

[0061] The above roll changing device, in the actual roll changing operation process, the material roll taking mechanism 43 transfers the standby material roll A1 provided by the material roll providing mechanism 20 to the roll out mechanism 31, the glue tape providing mechanism provides glue tape e and transfers the glue tape e to the tape connecting mechanism 30. When the working material roll on the roll out mechanism 31 is used up, the tape connecting mechanism 30 cuts the working material tape, and bonds the downstream cut end of the working material tape with the standby material tape A2 on the standby material roll A1 by using the glue tape e, so as to realize the connection of the standby material tape A2 and the working material tape. At this time, the standby material roll A1 on the roll out mechanism 31 is switched to the working material roll, and continues to output the working material tape downstream.

[0062] Therefore, the roll changing device can automatically complete the transfer of the adhesive tape e, the transfer of the standby roll A1, the adhesion of the downstream cut end of the working tape to the standby tape A2, and the like, thereby realizing automatic roll changing, without manual processing of the adhesive tape e and the standby roll A1, improving the automation degree of the roll changing device, improving the roll changing efficiency, and reducing the labor cost.

[0063] In the embodiment, the adhesive tape supply mechanism includes an adhesive tape unwinding assembly 11, a cutting assembly 12, and an adhesive tape taking assembly 42. The adhesive tape receiving mechanism 30 has an adhesive tape suction surface f for suctioning the adhesive tape e. The adhesive tape unwinding assembly 11 is configured to unwind and output the adhesive tape e. The cutting assembly 12 is arranged downstream of the adhesive tape unwinding assembly 11 and configured to cut the passing adhesive tape e. The adhesive tape taking assembly 42 has an adhesive tape suction roller 421 rotatable about an axis thereof. The adhesive tape taking assembly 42 is controllably movable to a position downstream of the cutting assembly 12 to fix the starting end of the adhesive tape e and wind the adhesive tape e. The adhesive tape taking assembly 42 is also controllably movable to abut against the adhesive tape suction surface f of the adhesive tape receiving mechanism 30 and roll along the adhesive tape suction surface f to flatten the adhesive tape e wound on the adhesive tape suction roller 421 on the adhesive tape suction surface f, thereby transferring the adhesive tape e to the adhesive tape suction surface f of the adhesive tape receiving mechanism 30.

[0064] It should be noted that in the prior art, a certain length of adhesive tape e is pulled out to the adhesive tape suction plate by the adhesive tape pulling mechanism, the pulled adhesive tape e is cut, and then the adhesive tape e on the adhesive tape suction plate is transferred to a designated position. Compared with the prior art, in the embodiment, the starting end of the adhesive tape e is fixed by the adhesive tape suction roller 421, and a certain length of the adhesive tape e is wound and then cut, thereby realizing the picking and transferring of the adhesive tape e, without the need for the adhesive tape pulling mechanism to pull the adhesive tape and the adhesive tape suction plate to suction the adhesive tape, greatly saving the required space, and making the structure more compact, so that the roll changing device is more suitable for space-limited working conditions.

[0065] Further, the adhesive tape supply mechanism further includes a driving assembly 41, a driving end of the driving assembly 41 being connected with the adhesive tape taking assembly 42, so that the driving assembly 41 can drive the adhesive tape taking assembly 42 to move to a position downstream of the cutting assembly 12 and to the adhesive tape receiving mechanism 30. When the driving assembly 41 drives the adhesive tape taking assembly 42 to move to the position downstream of the cutting assembly 12, the adhesive tape suction roller 421 can fix the starting end of the adhesive tape e and wind the adhesive tape e. When the driving assembly 41 drives the adhesive tape taking assembly 42 to move to the adhesive tape receiving mechanism 30, the adhesive tape suction roller 421 can abut against the adhesive tape suction surface f of the adhesive tape receiving mechanism 30 and roll along the adhesive tape suction surface f under the driving of the driving assembly 41, so that the adhesive tape e on the adhesive tape suction roller 421 is gradually flattened on the adhesive tape suction surface f, until the adhesive tape e is completely separated from the adhesive tape suction roller 421, i.e., the adhesive tape e is transferred to the adhesive tape suction surface f of the adhesive tape receiving mechanism 30.

[0066] Further, the taking mechanism 43 can also be installed at the driving end of the driving assembly 41, so that the driving assembly 41 can drive the taking mechanism 43 to move to the standby mechanism 20 and the unwinding mechanism 31. When the driving assembly 41 drives the taking mechanism 43 to move to the standby mechanism 20, the taking mechanism 43 can pick up the standby roll A1 provided by the standby mechanism 20; when the driving assembly 41 drives the taking mechanism 43 to move to the unwinding mechanism 31, the taking mechanism 43 can release the picked-up standby roll A1 to the unwinding mechanism 31, so as to realize the transfer of the standby roll A1. In this way, the taking mechanism 43 and the taking glue assembly 42 share the same driving assembly 41, compared with the scheme of respectively arranging driving components, the structure of the roll changing device is greatly simplified, and the device cost is reduced.

[0067] In some embodiments, the tape receiving mechanism 30 includes a tape receiving assembly 32 and a waste collecting assembly 33. The unwinding mechanism 31 is used to unwind and output the working tape to the tape receiving assembly 32, and receive the standby roll A1 transferred by the taking mechanism 43. The taking glue assembly 42 is also used to stick the tape starting end A3 of the standby roll A1 on the unwinding mechanism 31 by the adhesive tape e on the taking glue roller 421, and pull the tape starting end A3 through the tape receiving assembly 32 and the waste collecting assembly 33 in turn, so that the waste collecting assembly 33 can fix the standby tape A2, and prepare for subsequent roll changing. The tape receiving assembly 32 has the above-mentioned adhesive surface f for adsorbing the adhesive tape e. The tape receiving assembly 32 is used to cut the working tape and the standby tape A2 in the passing, and stick the downstream cut end of the working tape and the upstream cut end of the standby tape A2 by the adhesive tape e, so as to realize the mutual connection of the downstream cut end of the working tape and the upstream cut end of the standby tape A2, that is, realize the tape connection.

[0068] In actual use, first, the driving assembly 41 drives the glue taking assembly 42 to move to the downstream of the cutting assembly 12, so that the glue taking roller 421 of the glue taking assembly 42 winds the adhesive tape e at the downstream of the cutting assembly 12. The cutting assembly 12 cuts the adhesive tape e after the glue taking roller 421 of the glue taking assembly 42 winds a certain length. Then, the driving assembly 41 drives the glue taking assembly 42 to move to the unwinding mechanism 31, so that the glue taking assembly 42 sticks the starting end A3 of the standby tape A2 of the standby roll A1 on the unwinding mechanism 31 by the adhesive tape e on the glue taking roller 421. Then, the driving assembly 41 drives the glue taking assembly 42 to pass through the tape connecting assembly 32 and the waste collecting assembly 33 in turn, so as to pull out the standby tape A2 on the standby roll A1, so that the pulled-out standby tape A2 passes through the tape connecting assembly 32 and the waste collecting assembly 33 in turn and is fixed on the waste collecting assembly 33, on the one hand, the tape connecting assembly 32 can cut the working tape and the standby tape A2 at the same time when changing the roll, on the other hand, the part of the standby tape A2 between the tape connecting assembly 32 and the waste collecting assembly 33 after being cut becomes waste, and the waste collecting assembly 33 can wind the waste to form a waste roll A4, avoiding the interference of the waste to the tape connecting action of the tape connecting assembly 32.

[0069] It can be understood that the unwinding mechanism 31, the tape connecting assembly 32 and the waste collecting assembly 33 cooperate with each other to cut the working tape and the standby tape A2, and use the adhesive tape e to bond the downstream cut end of the working tape and the upstream cut end of the standby tape A2, which is a relatively mature prior art, and thus will not be described here.

[0070] It should be emphasized that the working tape is cut to form two cut ends at the break, of which the upstream cut end is located upstream and the downstream cut end is located downstream. Similarly, the standby tape is cut to form two cut ends at the break, of which the upstream cut end is located upstream and the downstream cut end is located downstream. The upstream and downstream in this article are relative to the conveying path of the tape, and the position where the tape arrives first is the upstream and the position where the tape arrives later is the downstream.

[0071] It should be noted that the part of the working tape between the tape connecting assembly 32 and the unwinding mechanism 31 after being cut by the tape connecting assembly 32 is also waste, which can be wound by the unwinding mechanism 31 to avoid the interference of the part of the waste to the tape connecting work of the tape connecting assembly 32.

[0072] Please refer to Figure 5, further, the glue taking assembly 42 can also abut against the spare roll A1 on the unwinding mechanism 31 by means of the glue suction roller 421, so that the adhesive tape e on the glue suction roller 421 is bonded with the starting end A3 of the spare roll A1, and the spare roll A2 on the spare roll A1 is wound by the glue suction roller 421. The glue taking assembly 42 can also pull the starting end A3 of the spare roll A2 through the tape connecting assembly 32 and the waste collecting assembly 33 by means of the glue suction roller 421, so that the spare roll A2 on the spare roll A1 passes through the tape connecting assembly 32 and is fixed on the waste collecting assembly 33.

[0073] It should be noted that the two sides of the adhesive tape e are the adhesive side and the non-adhesive side. Therefore, the direction of the adhesive side of the adhesive tape e wound on the glue suction roller 421 can be controlled by adjusting the rotating direction of the glue suction roller 421. That is to say, when the glue suction roller 421 is controlled to rotate in the first rotating direction (i.e. the counterclockwise direction in the embodiment shown), the adhesive side of the adhesive tape e wound on the glue suction roller 421 is located at the outer side and does not contact the glue suction roller 421, and the non-adhesive side is located at the inner side and contacts the roller surface of the glue suction roller 421. When the glue suction roller 421 is controlled to rotate in the second rotating direction (which is opposite to the first rotating direction), the adhesive side of the adhesive tape e wound on the glue suction roller 421 is located at the inner side and contacts the roller surface of the glue suction roller 421, and the non-adhesive side is located at the outer side and does not contact the glue suction roller 421. Figure 2 It should be noted that the two sides of the adhesive tape e are the adhesive side and the non-adhesive side. Therefore, the direction of the adhesive side of the adhesive tape e wound on the glue suction roller 421 can be controlled by adjusting the rotating direction of the glue suction roller 421. That is to say, when the glue suction roller 421 is controlled to rotate in the first rotating direction (i.e. the counterclockwise direction in the embodiment shown), the adhesive side of the adhesive tape e wound on the glue suction roller 421 is located at the outer side and does not contact the glue suction roller 421, and the non-adhesive side is located at the inner side and contacts the roller surface of the glue suction roller 421. When the glue suction roller 421 is controlled to rotate in the second rotating direction (which is opposite to the first rotating direction), the adhesive side of the adhesive tape e wound on the glue suction roller 421 is located at the inner side and contacts the roller surface of the glue suction roller 421, and the non-adhesive side is located at the outer side and does not contact the glue suction roller 421.

[0074] When the starting end A3 of the spare roll A1 needs to be bonded, the driving assembly 41 drives the glue taking assembly 42 to move to the downstream of the cutting assembly 12, 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 in the first rotating direction, until a certain length of the adhesive tape e is wound on the glue suction roller 421. Then, the cutting assembly 12 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 abuts against the starting end A3 of the spare roll A1. At this time, since the adhesive side of the adhesive tape e on the glue suction roller 421 is located at the outer side, the adhesive tape e and the starting end A3 of the spare roll A1 are bonded with each other. Then, the glue suction roller 421 is controlled to rotate around its axis, so as to wind the spare roll A2 on the spare roll A1 on the glue suction roller 421. Then, under the driving action of the driving assembly 41, the glue suction roller 421 pulls the spare roll A2 on the spare roll A1 through the tape connecting assembly 32 and the waste collecting assembly 33, and the waste collecting assembly 33 fixes the passing spare roll A2. Finally, the glue suction roller 421 is controlled to rotate in the second rotating direction, until the starting end A3 of the spare roll A2 and the adhesive tape e are completely separated from the glue suction roller 421.

[0075] When it is needed to transfer the adhesive tape e to the adhesive surface f of the tape receiving assembly 32, the driving assembly 41 drives the tape taking assembly 42 to move to the downstream of the cutting assembly 12, so that the suction roller 421 fixes the starting end of the adhesive tape e. The suction roller 421 is controlled to rotate along the second rotation direction until a certain length of the adhesive tape e is wound on the suction roller 421. At this time, the adhesive surface of the adhesive tape e on the suction roller 421 faces the inside. Then, the cutting assembly 12 is controlled to cut the adhesive tape e. Then, the driving assembly 41 drives the tape taking assembly 42 to move to the tape receiving assembly 32, so that the suction roller 421 abuts against the adhesive surface f. Then, under the driving action of the driving assembly 41, the suction roller 421 rolls along the adhesive surface f, and the rotation direction of the suction roller 421 is the first rotation direction, until the adhesive tape e is laid flat on the adhesive surface f and completely separated from the suction roller 421. At this time, the adhesive surface of the adhesive tape e faces away from the adhesive surface f, and the non-adhesive surface of the adhesive tape e faces the adhesive surface f and is adsorbed and fixed by the adhesive surface f, so as to facilitate subsequent pasting of the adhesive tape e between the downstream cut end of the work tape and the upstream cut end of the standby tape A2.

[0076] Please refer to Figures 11 to 14 In specific embodiments, the waste collecting assembly 33 comprises a first moving seat 334, a second rotation driving member 336 and a collecting roller 331. The second rotation driving member 336 is installed on the first moving seat 334 to move together with the first moving seat 334. The collecting roller 331 is installed on the first moving seat 334 and connected with the driving end of the second rotation driving member 336, so that the second rotation driving member 336 can drive the collecting roller 331 to rotate around its own axis.

[0077] The collecting roller 331 has an insertion slot k, and the first moving seat 334 can drive the collecting roller 331 to move along its own axis to make the standby tape A2 reaching the waste collecting assembly 33 together with the suction roller 421 enter the insertion slot k. After the standby tape A2 enters the insertion slot k of the collecting roller 331, the second rotation driving member 336 drives the collecting roller 331 to rotate, thereby driving the standby tape A2 to be arranged on the collecting roller 331. Optionally, the second rotation driving member 336 can be an electric motor.

[0078] Therefore, in actual use, first, the first moving seat 334 drives the collecting roller 331 to move along its own axis (i.e. to move inward along the paper surface direction as shown in Figure 1 ), so as to avoid interference of the collecting roller 331 to the suction roller 421 when the suction roller 421 pulls the tape starting end A3 of the standby tape A2 to move. Then, the tape starting end A3 of the standby tape A2 on the standby tape roll A1 passes through the tape receiving assembly 32 and the waste collecting assembly 33 in turn. Then, the first moving seat 334 drives the collecting roller 331 to move along its own axis (i.e. to move outward along the paper surface direction as shown in Figure 1When the waste material is collected on the waste material collecting assembly 33, the waste material collecting assembly 33 is moved to the waste material collecting position (i.e. moved outwardly along the paper surface direction as shown in the drawings) so that the standby material tape A2 passing through the waste material collecting assembly 33 enters the insertion slot k of the material collecting roller 331. Then, the suction roller 421 is controlled to rotate to unwind the material tape starting end A3 and the adhesive tape e of the standby material tape A2 until the suction roller 421 is separated from the material tape starting end A3 and the adhesive tape e of the standby material tape A2. At the same time, the second rotary driving member 336 drives the material collecting roller 331 to rotate to wind the material tape starting end A3 and the adhesive tape e of the standby material tape A2 on the material collecting roller 331 until the material tape starting end A3 and the adhesive tape e of the standby material tape A2 are both wound on the material collecting roller 331. It should be noted that the standby material tape A2 and the adhesive tape e wound on the material collecting roller 331 are the waste material roll A4.

[0079] Further, the waste material collecting assembly 33 further comprises a material pressing unit 332, which comprises 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 337 and is arranged apart from the material collecting roller 331, and the pressing block 3322 is movably connected to one side of the connecting seat 3321 facing the material collecting roller 331. The first elastic member 3323 is abutted between the connecting seat 3321 and the pressing block 3322, so that the pressing block 3322 is pressed against the waste material roll A4 wound on the material collecting roller 331 under the elastic force provided by the first elastic member 3323. In this way, the standby material tape A2 (i.e. the waste material roll A4) wound on the material collecting roller 331 is pressed tightly on the material collecting roller 331 by the pressing block 3322, so as to avoid the waste material roll A4 on the material collecting roller 331 from loosening or even falling off. Optionally, the first elastic member 3323 can be a compression spring.

[0080] Further, the waste collecting assembly 33 further comprises a guide rod 3324, a matching plate 3326 and a limiting block 3325. The connecting seat 3321 is provided with a guide hole, and the guide rod 3324 is arranged in the guide hole. One end of the guide rod 3324, which is close to the collecting roller 331, is fixedly connected with the pressing block 3322, and the other end of the guide rod 3324, which is away from the collecting roller 331, is fixedly connected with the matching plate 3326. The limiting block 3325 is installed on the connecting seat 3321, and the matching plate 3326 has a movement tendency of abutting against the limiting 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 collecting roller 331, the matching plate 3326 abuts against the limiting block 3325 under the elastic force provided by the first elastic member 3323, so as to limit the pressing block 3322 by the limiting block 3325, thereby avoiding that the pressing block 3322 directly abuts against the collecting roller 331, and further avoiding that the collecting roller 331 is bent and deformed due to long-term stress. When the waste roll A4 is wound on the collecting roller 331, the pressing block 3322 abuts against the waste roll A4 on the collecting roller 331, and as the diameter of the waste roll A4 gradually increases, the pressing block 3322 gradually moves to the connecting seat 3321 against the elastic force of the first elastic member 3323, thereby driving the matching plate 3326 to gradually move away from the limiting block 3325.

[0081] Further, the position of the limiting block 3325 on the connecting seat 3321 is adjustable, so as to adjust the gap between the pressing block 3322 and the collecting roller 331 by adjusting the position of the limiting block 3325, thereby ensuring that when the waste roll A4 is not wound on the collecting roller 331, there is a certain gap between the pressing block 3322 and the collecting roller 331, and when the waste roll A4 is wound on the collecting roller 331, the pressing block 3322 abuts against the waste roll A4.

[0082] Optionally, the limiting block 3325 is provided with a waist-shaped hole 3327, and the waste collecting assembly 33 further comprises a locking bolt (not shown in the figure). The locking bolt is arranged in the waist-shaped hole 3327 of the limiting block 3325 and is threadedly connected with the connecting seat 3321, so as to lock and fix the limiting block 3325 on the connecting seat 3321. In this way, the position of the limiting block 3325 is adjustable by cooperation of the locking bolt and the waist-shaped hole 3327.

[0083] Specifically in the embodiment, the roll changing device further comprises a mounting plate 70, and the collecting roller 331 is rotatably and movably connected to the mounting plate 70 along the axis of the collecting roller 331. The waste collecting assembly 33 further comprises 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 relative to the mounting plate 70 along the axis of the collecting roller 331, thereby driving the collecting roller 331 to move between the avoiding position and the winding position. Optionally, the moving driving member 335 can adopt a pneumatic cylinder.

[0084] Further, the scrap material collecting assembly 33 further comprises a guide 337 and a shaft sleeve 338, the shaft sleeve 338 is mounted on the mounting plate 70 through the guide 337, so that the shaft sleeve 338 can move along its own axis relative to the mounting plate 70. The material collecting roller 331 is sleeved inside the shaft sleeve 338 and can rotate relative to the shaft sleeve 338 around its own axis. One end of the material collecting roller 331 is drivingly connected with the second rotary driving member 336, and the other end of the material collecting roller 331 penetrates out of the shaft sleeve 338 and is used for winding the standby material belt A2 passing through. The insertion slot k is located at the part of the material collecting roller 331 penetrating out of the shaft sleeve 338. Optionally, the guide 337 can adopt a linear bearing.

[0085] Please refer to Figure 6 It should be noted that the unwinding mechanism 31 comprises two unwinding units, and the belt receiving assembly 32 comprises two belt receiving units. The two belt receiving units are spaced apart to form a belt receiving passage g. The two unwinding units are located on the same side of the two belt receiving units. Both of the two unwinding units can load a material roll (i.e. a working material roll or a standby material roll A1) and output a material belt (i.e. a working material belt or a standby material belt A2) to the belt receiving passage g. When the material roll loaded on one of the two unwinding units is a working material roll, the material belt output by the unwinding unit to the belt receiving passage g is a working material belt, and the working material belt continues to be conveyed downstream after passing through the belt receiving passage g. The material roll loaded on the other of the two unwinding units is a standby material roll A1, and the material belt of the standby material roll A1 passes through the belt receiving passage g and the material collecting roller 331 of the scrap material collecting assembly 33 under the traction of the suction roller 421, and then is fixed on the material collecting roller 331.

[0086] One of the two unwinding units and one of the two belt receiving units located on the same side form a group, which are respectively a first unwinding unit 31a and a first belt receiving unit 32a. The other of the two unwinding units and the other of the two belt receiving units located on the same side form another group, which are respectively a second unwinding unit 31b and a second belt receiving unit 32b.

[0087] It should be noted that the working material roll in this document refers to the material roll that is outputting a material belt to the downstream as a working material roll, and the material belt output by the working material roll to the downstream is a working material belt. The standby material roll in this document refers to the material roll that is not outputting a material belt to the downstream, and the material belt on the standby material roll is a standby material belt. For example, when the material roll on the first unwinding unit 31a is a working material belt, the first unwinding unit 31a drives the working material roll thereon to rotate, thereby conveying the working material belt to the downstream. The working material belt continues to be conveyed to the downstream after passing through the belt receiving passage g. At this time, the material roll on the second unwinding unit 32a is a standby material roll.

[0088] When the working material roll on the first unwinding unit 31a is unwound, a roll change is needed. After the roll change is completed, the standby material roll on the second unwinding unit 31a is switched to the working material roll, and the working material belt continues to be unwound and output to the downstream. At this time, the material taking mechanism 43 transfers the standby material roll A1 to the first unwinding unit 31a, and prepares for the next roll change.

[0089] 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 belt connecting unit 32a and the second belt connecting unit 32b is also small. Therefore, when the glue suction roller 421 pulls the starting end A3 of the material belt of the standby material roll A1 on the first unwinding unit 31a to pass through the belt connecting channel g and reach the downstream of the material collecting roller 331, the second unwinding unit 31b and the second belt connecting unit 32b are likely to interfere with the glue suction roller 421. Similarly, when the glue suction roller 421 pulls the starting end A3 of the material belt of the standby material roll A1 on the second unwinding unit 31b to pass through the belt connecting channel g and reach the downstream of the material collecting roller 331, the first unwinding unit 31a and the first belt connecting unit 32a are also likely to interfere with the glue suction roller 421.

[0090] In order to solve the problem of interference with the glue suction roller 421, in some embodiments, the first unwinding unit 31a is configured to be controllably movable along the axial direction of the material collecting roller 331. The first belt connecting unit 32a is controllably connected or separated from the first unwinding unit 31a. When the first belt connecting unit 32a is connected to the first unwinding unit 31a, the first belt connecting unit 32a can move along the axial direction of the material collecting roller 331 together with the first unwinding unit 31a. The second unwinding unit 31a is also configured to be controllably movable along the axial direction of the material collecting roller 331. The second belt connecting unit 32b is controllably connected or separated from the second unwinding unit 31b. When the second belt connecting unit 32b is connected to the second unwinding unit 31b, the second belt connecting unit 32b can move along the axial direction of the material collecting roller 331 together with the second unwinding unit 31b. It should be noted that a linear driving component such as an electric cylinder or a lead screw module can be used to drive the first unwinding unit 31a to move along the axial direction of the material collecting roller 331, which is not limited herein. A linear driving component such as an electric cylinder or a lead screw module can be used to drive the second unwinding unit 31b to move along the axial direction of the material collecting roller 331, which is not limited herein.

[0091] Furthermore, the first tape-attaching unit 32a and the second tape-attaching unit 32b can be selectively connected to the first moving seat 334. When the first tape-attaching unit 32a is connected to the first moving seat 334, the second tape-attaching unit 32b is separated from the first moving seat 334, thereby enabling the take-up roller 331 and the first tape-attaching unit 32a to move synchronously along the axial direction of the take-up roller 331. When the second tape-attaching unit 32b is connected to the first moving seat 334, the first tape-attaching unit 32a is separated from the first moving seat 334, thereby enabling the take-up roller 331 and the second tape-attaching unit 32b to move synchronously along the axial direction of the take-up roller 331.

[0092] Thus, when the roll on the first unwinding unit 31a is the spare roll A1, the first tape-connecting unit 32a is connected to the first unwinding unit 31a. At this time, the first unwinding unit 31a is moved axially along the take-up roller 331 (i.e., along...). Figure 1 The first unwinding unit 31a moves outward perpendicular to the paper surface, thereby also causing the first tape-joining unit 32a to move axially along the take-up roller 331. This causes the first unwinding unit 31a and the second unwinding unit 31b to be misaligned axially along the take-up roller 331, and the first tape-joining unit 32a and the second tape-joining unit 32b to also be misaligned axially along the take-up roller 331. This ensures that during the process of the glue suction roller 421 pulling the starting end A3 of the spare tape A2 on the first unwinding unit 31a through the tape-joining channel g and reaching the downstream of the take-up roller 331, there will be no interference with the second unwinding unit 31b, the second tape-joining unit 32b, and the take-up roller 331. After the glue suction roller 421 pulls the starting end A3 of the spare tape A2 to the downstream of the take-up roller 331, the first moving seat 334 moves axially along the take-up roller 331 (i.e., along the direction perpendicular to the paper surface). Figure 1 The unwinding unit 31a, the first tape receiving unit 32a, and the take-up roller 331 move together along the axial direction of the take-up roller 331 to the winding position, so that the take-up roller 331 can fix and wind up the spare tape A2. Finally, the first motion seat 334 is connected to the first tape receiving unit 32a, so that the first unwinding unit 31a, the first tape receiving unit 32a and the take-up roller 331 move together along the axial direction of the take-up roller 331 to reset (i.e., along the axial direction of the take-up roller 331). Figure 1 (Move inwards in a direction perpendicular to the paper surface) so that the two unwinding units, two splicing units, and waste collection assembly can work together to complete the splicing.

[0093] When the roll on the second unwinding unit 31b is the spare roll A1, the second tape-connecting unit 32b is connected to the second unwinding unit 31b. At this time, the second unwinding unit 31b is moved axially along the take-up roller 331 (i.e., along...). Figure 1The first spooling unit 31a and the first splicing unit 32a are moved to the splicing position along the axial direction of the take-up roller 331, and the second spooling unit 31b and the second splicing unit 32b are moved to the splicing position along the axial direction of the take-up roller 331 at the same time, so that the spare tape A2 on the second spooling unit 31b is spliced to the tape A1 on the first spooling unit 31a by the suction roller 421. After the spare tape A2 is spliced to the tape A1, the first moving seat 334 is moved to the take-up position along the axial direction of the take-up roller 331, so that the take-up roller 331 is moved to the take-up position along the axial direction of the take-up roller 331, and the tape A1 is fixed and wound on the take-up roller 331. Finally, the first moving seat 334 is connected with the second splicing unit 32b, so that the second spooling unit 31b, the second splicing unit 32b and the take-up roller 331 are moved to the original position (i.e. moved to the original position along the axial direction of the take-up roller 331) along the axial direction of the take-up roller 331, so that the tape A1 on the first spooling unit 31a is ready for the next splicing operation. Figure 1 The first spooling unit 31a and the first splicing unit 32a are moved to the splicing position along the axial direction of the take-up roller 331, and the second spooling unit 31b and the second splicing unit 32b are moved to the splicing position along the axial direction of the take-up roller 331 at the same time, so that the spare tape A2 on the second spooling unit 31b is spliced to the tape A1 on the first spooling unit 31a by the suction roller 421. After the spare tape A2 is spliced to the tape A1, the first moving seat 334 is moved to the take-up position along the axial direction of the take-up roller 331, so that the take-up roller 331 is moved to the take-up position along the axial direction of the take-up roller 331, and the tape A1 is fixed and wound on the take-up roller 331. Finally, the first moving seat 334 is connected with the second splicing unit 32b, so that the second spooling unit 31b, the second splicing unit 32b and the take-up roller 331 are moved to the original position (i.e. moved to the original position along the axial direction of the take-up roller 331) along the axial direction of the take-up roller 331, so that the tape A1 on the first spooling unit 31a is ready for the next splicing operation.

[0094] Specifically, the splicing mechanism 30 further comprises a first clutch assembly 34, which comprises a clutch sliding seat 342 and a clutch driving member 341. The clutch sliding seat 342 is movably connected to the first moving seat 334. The clutch driving member 341 is installed on the first moving seat 334, and the driving end of the clutch driving member 341 is connected to the clutch sliding seat 342. The clutch driving member 341 can drive the clutch sliding seat 342 to move to a first position connected with the first splicing unit 32a and a second position connected with the second splicing unit 32b relative to the first moving seat 334.

[0095] It should be noted that in some embodiments, the clutch sliding seat 342 is provided with a matching groove or hole. When the clutch sliding seat 342 moves to the first position, part of the first splicing unit 32a is inserted into the matching groove or hole, so as to realize the connection between the first splicing unit 32a and the clutch sliding seat 342, so that the first moving seat 334 can drive the first splicing unit 32a to move along the axial direction of the take-up roller 331. When the clutch sliding seat 342 moves to the second position, part of the second splicing unit 32b is inserted into the matching groove or hole, so as to realize the connection between the second splicing unit 32b and the clutch sliding seat 342, so that the first moving seat 334 can drive the second splicing unit 32b to move along the axial direction of the take-up roller 331. Of course, in other embodiments, the clutch sliding seat 342 and the first splicing unit 32a or the second splicing unit 32b can also be connected in other ways, such as clamping, which is not limited herein.

[0096] Specifically, the tape receiving mechanism 30 further comprises a second clutch assembly (not shown) and a third clutch assembly 36. The second clutch assembly is arranged between the first unwinding unit 31a and the first tape receiving unit 32a, and is used to control the connection or disconnection between the first unwinding unit 31a and the first tape receiving unit 32a. The third clutch assembly 36 is arranged between the second unwinding unit 31b and the second tape receiving unit 32b, and is used to control the connection or disconnection between the second unwinding unit 31b and the second tape receiving unit 32b.

[0097] Further, the second clutch assembly comprises a first clamping part and a first connecting part, one of which is mounted on the first unwinding unit 31a, and the other of which is mounted on the first tape receiving unit 32a. The first clamping part can be controlled to clamp or release the first connecting part. When the first clamping part clamps the first connecting part, the first tape receiving unit 32a and the first unwinding unit 31a are connected as a whole through the first clamping part and the first connecting part, and can move synchronously along the axial direction of the material collecting roller 331. When the first clamping part releases the first connecting part, the first tape receiving unit 32a and the first unwinding unit 31a are disconnected, and cannot move together along the axial direction of the material collecting roller 331. It should be noted that the first clamping part can adopt a jaw structure, as long as it can clamp or release the first connecting part, which is not limited herein.

[0098] Further, the third clutch assembly 36 comprises a second clamping part 361 and a second connecting part 362, one of which is mounted on the second unwinding unit 31b, and the other of which is mounted on the second tape receiving unit 32b. The second clamping part 361 can be controlled to clamp or release the second connecting part 362. When the second clamping part 361 clamps the second connecting part 362, the second tape receiving unit 32b and the second unwinding unit 31b are connected as a whole through the second clamping part 361 and the second connecting part 362, and can move synchronously along the axial direction of the material collecting roller 331. When the second clamping part 361 releases the second connecting part 362, the second tape receiving unit 32b and the second unwinding unit 31b are disconnected, and cannot move together along the axial direction of the material collecting roller 331. It should be noted that the second clamping part 361 can adopt a jaw structure, as long as it can clamp or release the second connecting part 362, which is not limited herein.

[0099] It should be noted that the movement of the first tape receiving unit 32a along the axial direction of the material collecting roller 331 is not limited to the mode of driving the first tape receiving unit 32a by the first unwinding unit 31a. In other embodiments, a driving component can be arranged to drive the first tape receiving unit 32a to move along the axial direction of the material collecting roller 331.

[0100] Similarly, the second tape receiving unit 32b is not limited to be moved along the axis of the material receiving roller 331 by the second unwinding unit 31a. In other embodiments, a driving component can be provided to drive the second tape receiving unit 32b to move along the axis of the material receiving roller 331.

[0101] It should be further noted that the standby material roll A1 can be located on the first unwinding unit 31a or the second unwinding unit 31b. In order to avoid the standby material tape A2 interfering with the working material tape to be conveyed downstream, in some embodiments, the material receiving assembly 33 is provided with two material receiving rollers 331, which are a first material receiving roller and a second material receiving roller. The first material receiving roller is located on the same side as the first unwinding unit 31a and the first tape receiving unit 32a, and the second material receiving roller is located on the same side as the second unwinding unit 31b and the second tape receiving unit 32b. In this way, when the standby material roll A1 is located on the first unwinding unit 31a, the standby material tape A2 of the standby material roll A1 pulled out by the suction roller 421 passes through the first unwinding unit 31a and the first tape receiving unit 32a in sequence and is wound onto the first material 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 suction roller 421 passes through the second unwinding unit 31b and the second tape receiving unit 32b in sequence and is wound onto the second material receiving roller.

[0102] It should be noted that in some embodiments, the two material receiving rollers 331 can be driven by two second rotary driving members 336 respectively, so as to rotate around their respective axes. Of course, in other embodiments, one second rotary driving member 336 can be used to synchronously drive the two material receiving rollers 331 to rotate. Specifically, the material receiving assembly 33 further comprises a driving wheel L1, a driven wheel L2 and a transmission belt L3. The driving wheel L1 and the driven wheel L2 are respectively mounted on the two material receiving rollers 331, and the transmission belt L3 is sleeved between the driving wheel L1 and the driven wheel L2. The driving end of the second rotary driving member 336 is connected with one of the material receiving rollers 331, so that when the one of the material receiving rollers 331 rotates under the driving action of the second rotary driving member 336, the other material receiving roller 331 can be synchronously rotated by the driving wheel L1, the transmission belt L3 and the driven wheel L2. In this way, the two material receiving rollers 331 share one second rotary driving member 336, which is conducive to reducing the cost of the device.

[0103] Please refer to Figures 6 to 8In some embodiments, the glue taking assembly 42 comprises a first mounting base 418, a first rotary driving member 422 and a first rotary base 423. The first mounting base 418 is mounted on the driving end of the driving assembly 41, so that the driving assembly 41 can drive the first mounting base 418 to move. The first rotary driving member 422 is mounted on the first mounting base 418, and the first rotary base 423 is mounted on the driving end of the first rotary driving member 422, so that the first rotary driving member 422 can drive the first rotary base 423 to rotate. The above-mentioned glue suction roller 421 is mounted on the first rotary base 423, so that the glue suction roller 421 can rotate with the first rotary base 423.

[0104] The driving assembly 41 is used to drive the first mounting base 418 to move along the first direction X1 and the second direction X2, or along the first direction X1, the second direction X2 and the third direction X3, and the first rotary driving member 422 is used to drive the first rotary base 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 are perpendicular to each other. In this way, by driving the first mounting base 418 to move along the first direction X1 and the second direction X2, or along the first direction X1, the second direction X2 and the third direction X3 by the driving assembly 41, the first mounting base 418 can accurately drive the glue suction roller 421 to pick up the adhesive tape e downstream of the cutting assembly 12, release the adhesive tape e onto the glue suction surface f at the tape connecting assembly 32, stick the starting end A3 of the adhesive tape A1 on the standby roll A1 at the unwinding mechanism 31, and pull the standby adhesive tape A2 through the tape connecting assembly 32 and the waste collecting assembly 33 in turn. By driving the glue suction roller 421 to rotate around its own axis by the first rotary driving member 422 (i.e. the glue suction roller 421 rotates in the first direction or the second direction), the adhesive tape e or the standby adhesive tape A2 can be wound or released.

[0105] Preferably, the first direction X1, the second direction X2 and the third direction X3 are perpendicular to each other. Specifically Figure 1 In the embodiment shown, 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, which 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, which means that the third direction X3 is substantially parallel to the axial direction of the glue suction roller 421.

[0106] Specifically, the tape taking assembly 42 further comprises a first sliding seat 424 and a second sliding seat 425, both of which are arranged on the first rotating seat 423. The tape suction roller 421 comprises a first suction half roller 4211 mounted on the first sliding seat 424 and a second suction half roller 4213 mounted on the second sliding seat 425. The surfaces of the first suction half roller 4211 and the second suction half roller 4213, which are away from each other, jointly form a roller surface for winding the tape e. The first sliding seat 424 and the second sliding seat 425 can drive the first suction half roller 4211 and the second suction half roller 4213 to move close to or away from each other, so as to clamp or release the starting end of the tape e. In this way, when it is needed to pick up the tape e downstream of the cutting assembly 12, first, the first sliding seat 424 and the second sliding seat 425 drive the first suction half roller 4211 and the second suction half roller 4213 to move away from each other. The driving assembly 41 drives the tape taking assembly 42 to move to the downstream of the cutting assembly 12, so that the starting end of the tape e is inserted between the first suction half roller 4211 and the second suction half roller 4213. Then, the first sliding seat 424 and the second sliding seat 425 drive the first suction half roller 4211 and the second suction half roller 4213 to move close to each other until the starting end of the tape e between them is clamped. Then, the first rotating drive 422 drives the first suction half roller 4211 and the second suction half roller 4213 to rotate in the first rotation direction or the second rotation direction until a certain length of the tape e is wound on the first suction half roller 4211 and the second suction half roller 4213. Finally, the cutting assembly 12 is controlled to cut the tape e, so as to realize that the tape suction roller 421 picks up a certain length of the tape e. It should be noted that in the embodiment, the first sliding seat 424 and the second sliding seat 425 are both movable, and in other embodiments, only one of the first sliding seat 424 and the second sliding seat 425 is movable, as long as it can clamp or release the starting end of the tape e, which is not limited herein. For the convenience of understanding, the first sliding seat 424 and the second sliding seat 425 are both movable in the description herein.

[0107] Further, the surfaces of the first suction half roller 4211 and the second suction half roller 4213, which are away from each other, are both suction surfaces h for adsorbing the tape e wound thereon, so as to avoid that the tape e wound on the first suction half roller 4211 and the second suction half roller 4213 is loose or even falls off. Optionally, the suction surfaces h can adsorb and fix the tape e in a vacuum adsorption manner. Specifically, a plurality of suction holes are arranged on the suction surface h, and each suction hole is in communication with an external negative pressure source, so that the external negative pressure source can form a negative pressure at each suction hole, and then the negative pressure can adsorb and fix the tape e on the suction surface h.

[0108] Further, the glue taking assembly 42 further comprises a first clamping driving member 426 and a second clamping driving member 427, which are both mounted on the first rotating base 423. The driving end of the first clamping driving member 426 is connected with the first sliding base 424, so that the first clamping driving member 426 can drive the first sliding base 424 to move close to or away from the second sliding base 425, thereby driving the first adsorption half roller 4211 to move close to or away from the second adsorption half roller 4213. The driving end of the second clamping driving member 427 is connected with the second sliding base 425, so that the second clamping driving member 427 can drive the second sliding base 425 to move close to or away from the first sliding base 424, thereby driving the second adsorption half roller 4213 to move close to or away from the first adsorption half roller 4211. Optionally, the first clamping driving member 426 and the second clamping driving member 427 can both be air cylinders.

[0109] Thus, when the glue taking roller 421 needs to clamp the glue tape e downstream of the cutting assembly 12, the first clamping driving member 426 drives the first adsorption half roller 4211 to move close to the second adsorption half roller 4213, while the second clamping driving member 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 glue tape e therebetween.

[0110] When the first adsorption half roller 4211 of the glue taking roller 421 abuts against the glue taking surface f of the glue receiving assembly 32, the glue tape e needs to be released, the second clamping driving member 427 drives the second adsorption half roller 4213 to move away from the first adsorption half roller 4211, thereby releasing the glue tape e. At this time, the first clamping driving member 426 does not drive the first adsorption half roller 4211 to move, thereby avoiding that the pressing force of the first adsorption half roller 4211 against the glue taking surface f is too large to crush the glue tape e.

[0111] When the second adsorption half roller 4213 of the glue taking roller 421 abuts against the glue taking surface f of the glue receiving assembly 32, the glue tape e needs to be released, the first clamping driving member 426 drives the first adsorption half roller 4211 to move away from the second adsorption half roller 4213, thereby releasing the glue tape e. At this time, the second clamping driving member 427 does not drive the second adsorption half roller 4213 to move, thereby avoiding that the pressing force of the second adsorption half roller 4213 against the glue taking surface f is too large to crush the glue tape e.

[0112] Further, the first rotating seat 423 is provided with a first sliding rail, the first sliding seat 424 and the second sliding seat 425 are arranged on the first sliding rail, so that the first sliding seat 424 can move along the first sliding rail under the driving action of the first clamping driving member 426, and the second sliding seat 425 can also move along the first sliding rail under the driving action of the second clamping driving member 427, so as to respectively drive the first adsorption half roller 4211 and the second adsorption half roller 4213 to move close to or away from each other. In this way, the movement of the first sliding seat 424 and the second sliding seat 425 is guided by the first sliding rail, which ensures that the clamping and loosening actions of the first adsorption half roller 4211 and the second adsorption half roller 4213 are more accurate and reliable.

[0113] In some embodiments, the driving assembly 41 comprises a driving unit 410, a third moving seat 416 and an elastic buffer 419. The third moving seat 416 is installed on the driving end of the driving unit 410, and the first mounting seat 418 is movably connected to the third moving seat 416, so that the driving unit 410 can drive the first mounting seat 418 to move through the third moving seat 416, and then drive the glue absorbing roller 421 to move together. The two ends of the elastic buffer 419 are connected with the first mounting seat 418 and the third moving seat 416 respectively, so that the elastic buffer 419 can buffer the impact borne by the glue absorbing roller 421. In this way, when the first mounting seat 418 drives the glue absorbing roller 421 to press against the glue absorbing surface f of the tape receiving assembly 32, the first mounting seat 418 can float relative to the third moving seat 416 under the pressing force to further compress the elastic buffer 419, so as to buffer the impact force between the glue absorbing roller 421 and the glue absorbing surface f, and avoid hard impact between the glue absorbing roller 421 and the glue absorbing surface f to crush the adhesive tape e.

[0114] Similarly, when the first mounting seat 418 drives the glue absorbing roller 421 to press against the standby roll A1, the first mounting seat 418 can float relative to the third moving seat 416 under the pressing force to further compress the elastic buffer 419, so as to buffer the impact force between the glue absorbing roller 421 and the standby roll A1, and avoid hard impact between the glue absorbing roller 421 and the standby roll A1 to crush the adhesive tape e or the standby roll A1.

[0115] It should be noted that the elastic buffer 419 can adopt a gas cylinder or a spring or other elastic device capable of generating a buffering force. In the embodiment in which the elastic buffer 419 adopts a gas cylinder, since the buffering force output by the gas cylinder can remain constant and does not increase with the increase of the compression amount, it can ensure that the pressing force between the glue absorbing roller 421 and the glue absorbing surface f or the standby roll A1 remains constant, thereby avoiding excessive or insufficient pressing force.

[0116] In specific embodiments, the driving unit 410 comprises 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 along with the first transfer seat 413. The second transfer seat 415 is movably connected on the first transfer seat 413 along the second direction X2, and is connected with 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 along the second direction X2 relative to the first transfer seat 413. The third driving member 417 is installed on the second transfer seat 415, so that the third driving member 417 can move along with the second transfer seat 415. The third transfer seat 416 is movably connected on the second transfer seat 415 along the third direction X3, and is connected with 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 along the third direction X3 relative to the second transfer seat 415. The above-mentioned first mounting seat 418 is movably connected on the third transfer seat 416 along the second direction X2, so that the first mounting seat 418 can move along with the third transfer seat 416, thereby driving the glue roller 421 to move along with the third transfer seat 416.

[0117] Thus, by driving the glue roller 421 to move along the first direction X1 by the translation driving member 411, driving the glue roller 421 to move along the third direction X3 by the first driving member 412, driving the glue roller 421 to move along the second direction X2 by the second driving member 414, driving the glue roller 421 to move along the third direction X3 by the third driving member 417, and driving the glue roller 421 to rotate around its own axis by the first rotary driving member 422, the glue roller 421 can accurately complete the actions of transferring the adhesive tape e, sticking the starting end A3 of the adhesive tape on the standby roll A1 by the adhesive tape e, and pulling the standby adhesive tape A2 through the tape connecting assembly 32 and the waste collecting assembly 33 in sequence. It should be noted that the translation driving member 411, the first driving member 412, the second driving member 414 and the third driving member 417 can adopt a linear driving module such as a pneumatic cylinder, an electric cylinder or a synchronous belt driving mechanism, as long as it can accurately move the glue roller 421, which is not limited here.

[0118] Further, the first transfer seat 413 is provided with a second sliding rail which longitudinally extends along the second direction X2. The second transfer seat 415 is slidingly arranged on the second sliding rail, so that the second sliding rail guides the movement of the second transfer seat 415 along the second direction X2 relative to the first transfer seat 413.

[0119] Furthermore, a third slide rail is provided on the second transfer seat 415, which extends longitudinally along the third direction X3. The third transfer seat 416 is slidably disposed on the third slide rail, thereby guiding the movement of the third transfer seat 416 relative to the second transfer seat 415 along the third direction X3.

[0120] Furthermore, a fourth slide rail is provided on the third transfer seat 416, which extends longitudinally along the second direction X2. The first mounting seat 418 is slidably mounted on the fourth slide rail, thereby guiding the movement of the first mounting seat 418 relative to the third transfer seat 416 along the second direction X2 using the fourth slide rail.

[0121] Please see again Figure 2 and Figure 3 In the embodiments of this application, the adhesive preparation mechanism further includes a mounting base 16 and a first clamping assembly 13 and a second clamping assembly 14, both mounted on the mounting base 16. The tape unwinding assembly 11 and the cutting assembly 12 are both mounted on the mounting base 16. The first clamping assembly 13 is located upstream of the cutting assembly 12 and is used to clamp or release the passing tape e. The second clamping assembly 14 is located downstream of the cutting assembly 12 and is used to clamp or release the passing tape e. Thus, during the process of the suction roller 421 clamping and fixing the starting end of the tape e and winding the tape e, both the first clamping assembly 13 and the second clamping assembly 14 remain in a state of releasing the tape e, allowing the tape e to be conveyed downstream and wound onto the suction roller 421 under its traction. After the suction roller 421 has wound a certain length of tape e, the suction roller 421 stops rotating, and the first clamping assembly 13 and the second clamping assembly 14 each clamp the passing tape e. Then, the cutting component 12 cuts the passing tape e, so that the suction roller 421 can carry the tape e wound on it together to the suction surface f of the tape receiving component 32 or the spare roll A1 on the unwinding mechanism 31.

[0122] Specifically, the cutting assembly 12 includes a cutting drive (not shown) and a cutter (not shown). The cutting drive is mounted on the mounting base plate 16, and the cutter is mounted on the drive end of the cutting drive, enabling the cutting drive to drive the cutter to perform a cutting action, thereby cutting the passing tape e. Optionally, the cutting drive can be a cylinder.

[0123] Specifically, the first clamping assembly 13 comprises a first clamping driving member (not labeled in the figure) and two first clamping blocks (not labeled in the figure). The first clamping driving member is installed on the installation base plate 16, and the two first clamping blocks are respectively installed on two driving ends of the first clamping driving member, and a first clamping channel for the adhesive tape e to pass through is formed between the two first clamping blocks. The first clamping driving member is used to drive the two first clamping blocks to clamp or release the adhesive tape e therebetween. Optionally, the first clamping driving member can adopt a clamping jaw air cylinder.

[0124] Specifically, the second clamping assembly 14 comprises a second clamping driving member (not labeled in the figure) and two second clamping blocks (not labeled in the figure). The second clamping driving member is installed on the installation base plate 16, and the two second clamping blocks are respectively installed on two driving ends of the second clamping driving member, and a second clamping channel for the adhesive tape e to pass through is formed between the two second clamping blocks. The second clamping driving member is used to drive the two second clamping blocks to clamp or release the adhesive tape e therebetween. Optionally, the second clamping driving member can adopt a clamping jaw air cylinder.

[0125] Further, the adhesive preparation mechanism further comprises a buffer assembly 15 installed on the installation base plate 16. The buffer assembly 15 is located between the cutting assembly 12 and the adhesive tape unwinding assembly 11, and is used to buffer the passing adhesive tape e. In this way, the adhesive tape e is buffered by the buffer assembly 15, so that in the process of winding the adhesive tape e by the suction roller 421, the buffer assembly 15 releases the adhesive tape e (i.e. the amount of buffered adhesive tape e decreases), and the adhesive tape e released by the buffer assembly 15 is finally wound onto the suction roller 421, thereby avoiding the suction roller 421 directly pulling out the adhesive tape e from the adhesive tape unwinding assembly 11 when winding the adhesive tape e, and further avoiding the adhesive tape e being pulled off due to excessive tension.

[0126] Specifically, the buffer assembly 15 comprises a fixed over roller 151 and a movable over roller 152 arranged on the installation base plate 16. The fixed over roller 151 is fixed relative to the position of the installation base plate 16, and the movable over roller 152 can move close to or away from the fixed over roller 151 under the action of an external force. In this way, when the suction roller 421 winds the adhesive tape e, the adhesive tape e drives the movable over roller 152 to move close to the fixed over roller 151, so that the length of the adhesive tape e buffered between the movable over roller 152 and the fixed over roller 151 decreases. When the suction roller 421 stops winding the adhesive tape e, the movable over roller 152 moves away from the fixed over roller 151 to reset, so that the length of the adhesive tape e buffered between the movable over roller 152 and the fixed over roller 151 increases.

[0127] Further, the buffer assembly 15 further comprises a movable block 153 and a buffer driving member 154. The movable block 153 is movably connected to the mounting base 16, and the movable roller 152 is mounted on the movable block 153, so that the movable roller 152 can move together with the movable block 153 relative to the mounting base 16, thereby approaching or moving away from the fixed roller 151. The buffer driving member 154 is mounted on the mounting base 16, and the buffer driving member 154 is configured to provide a driving force for moving the movable block 152 and the movable roller 152 away from the fixed roller 151. In this way, when the adhesive 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 buffered between the movable roller 152 and the fixed roller 151 is reduced. When the adhesive 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 under the driving action of the buffer driving member 154, thereby increasing the length of the adhesive tape e buffered between the movable roller 152 and the fixed roller 151. Alternatively, the buffer driving member 154 can be a pneumatic cylinder.

[0128] Further, the mounting base 16 is provided with a fifth slide rail (not labeled in the figure), and the movable block 153 is slidably arranged on the fifth slide rail, so that the fifth slide rail guides the movement of the movable block 153 relative to the mounting base 16.

[0129] Please refer to Figures 15 to 17 and Figure 20 In the embodiment of the present application, the material preparation mechanism 20 comprises a support seat 21, a storage shaft 22 and a material pushing assembly 23. The storage shaft 22 has an installation end a1 and an in-out material end a2 at both axial ends. The installation end a1 of the storage shaft 22 is mounted on the support seat 21, and the storage shaft 22 is configured to axially install at least one standby roll A1. The material taking mechanism 43 has a material taking shaft 431 (see Figure 18The drive assembly 41 drives the picking mechanism 43 to move to the preparation mechanism 20, so that the picking shaft 431 of the picking mechanism 43 is axially aligned with the inlet / outlet end a2 of the storage shaft 22 of the preparation mechanism 20. The push assembly 23 is mounted on the support base 21 and is used to push the spare material rolls A1 on the storage shaft 22 to move past the inlet / outlet end a2 of the storage shaft 22 to the picking shaft 431. Thus, in actual use, firstly, the drive assembly 41 drives the picking mechanism 43 to move to the preparation mechanism 20, so that the picking shaft 431 of the picking mechanism 43 is axially aligned with the inlet / outlet end a2 of the storage shaft 22 of the preparation mechanism 20. Then, the push assembly 23 pushes each spare material roll A1 on the storage shaft 22 toward the inlet / outlet end a2 of the storage shaft 22 until the spare material roll A1 closest to the inlet / outlet end a2 of the storage shaft 22 passes the inlet / outlet end a2 and moves to the picking shaft 431. Then, the drive assembly 41 drives the take-up mechanism 43 to move toward the unwinding mechanism 31 to transfer the spare roll A1 on the take-up shaft 431 to the unwinding mechanism 31.

[0130] In some embodiments, the feeding assembly 23 includes a feeding drive 231, a telescopic unit 233, and a feeding block 232. The feeding drive 231 is mounted on the support base 21, and the feeding block 232 is disposed on the storage shaft 22. The telescopic unit 233 is connected between the feeding drive 231 and the feeding block 232. The feeding drive 231 is used to drive the telescopic unit 233 to extend and retract, thereby causing the feeding block 232 to move along the storage shaft 22, thereby pushing each spare material roll A1 on the storage shaft 22 toward the inlet / outlet end a2 of the storage shaft 22.

[0131] Further, the telescopic unit 233 includes a first movable seat 2331, a connecting rod telescopic frame 2336, a second movable seat 2333, and a second mounting seat 2335. The first movable seat 2331 is mounted on the drive end of the pusher drive member 231, which drives the first movable seat 2331 to move along a first direction X1. The second movable seat 2333 is movably connected to the second mounting seat 2335, and the pusher block 232 is mounted on the second movable seat 2333. The connecting rod telescopic frame 2336 is hinged between the first movable seat 2331 and the second movable seat 2333, and is used to convert the movement of the first movable seat 2331 along the first direction X1 into the movement of the pusher block 232 along a third direction X3. This third direction X3 is aligned with the axial direction of the storage shaft 22. Thus, when material needs to be pushed, the pushing drive 231 drives the first moving seat 2331 to move along the first direction X1, thereby causing the connecting rod telescopic frame 2336 to extend along the axial direction of the storage shaft 22, thereby driving the second mounting seat 2335 and the pushing block 232 to move along the axial direction of the storage shaft 22, thereby realizing the movement of each spare material roll A1 on the storage shaft 22 towards the inlet / outlet end a2 of the storage shaft 22.

[0132] It should be noted that using the telescopic linkage 2336 for transmission is beneficial to convert the smaller stroke output by the pusher drive 231 into the larger stroke of the pusher block 232. On the one hand, it helps to reduce the size of the pusher drive 231 and reduce equipment costs; on the other hand, it makes the structure more compact, reduces the space required, especially the space occupied in the axial direction of the storage shaft 22, and improves space utilization.

[0133] Specifically, the linkage telescopic frame 2336 includes a plurality of first links b1 arranged parallel to each other and spaced apart, and a plurality of second links b2 arranged parallel to each other and spaced apart. Each first link b1 and each second link b2 are arranged in a one-to-one correspondence. Each first link b1 and its corresponding second link b2 are hinged at the intersection, and the end of each first link b1 is hinged to the end of the adjacent second link b2.

[0134] The telescopic unit 233 also includes a first fixed seat 2332 and a second fixed seat 2334. The first fixed seat 2332 is mounted on the support seat 21 and is spaced apart from the first movable seat 2331 along the first direction X1. The second fixed seat 2334 is mounted on the second mounting seat 2335 and is spaced apart from the second movable seat 2333 along the first direction X1. At the end of the linkage telescopic frame 2336 near the first movable seat 2331: one of the ends of the first connecting rod b1 and the second connecting rod b2 is hinged to the first movable seat 2331, and the other is hinged to the first fixed seat 2332. At the end of the linkage telescopic frame 2336 near the second movable seat 2333: one of the ends of the first connecting rod b1 and the second connecting rod b2 is hinged to the second movable seat 2333, and the other is hinged to the second fixed seat 2334.

[0135] Thus, when the pusher drive 231 drives the first movable seat 2331 to move closer to the first fixed seat 2332, it can gradually reduce the intersection angle θ of each set of intersecting first connecting rods b1 and second connecting rods b2, causing the connecting rod telescopic frame 2336 to extend axially along the storage shaft 22, thereby driving the second mounting seat 2335 and the pusher block 232 to move axially along the storage shaft 22 toward the inlet / outlet end a2. During the extension process, the connecting rod telescopic frame 2336 drives the second movable seat 2333 to gradually move closer to the second fixed seat 2334.

[0136] When the pusher drive 231 drives the first movable seat 2331 to move away from the first fixed seat 2332, it can gradually increase the intersection angle θ of each set of intersecting first connecting rods b1 and second connecting rods b2, causing the connecting rod telescopic frame 2336 to retract axially along the storage shaft 22, thereby driving the second mounting seat 2335 and the pusher block 232 to move axially along the storage shaft 22 towards the mounting end a1. During the retraction process, the connecting rod telescopic frame 2336 drives the second movable seat 2333 to gradually move away from the second fixed seat 2334.

[0137] In a specific embodiment, the pushing assembly 23 further includes a first support roller 234 rotatably connected to the pushing block 232. The pushing block 232 is supported on the storage shaft 22 by the first support roller 234, so that when the connecting rod telescopic frame 2336 drives the pushing block 232 to move axially along the storage shaft 22, the first support roller 234 rolls on the storage shaft 22, which helps to reduce the thrust required to push each spare material roll A1 to move axially along the storage shaft 22 and reduces the difficulty of pushing.

[0138] It should be noted that the number of first support rollers 234 can be one, two, or more. When there is only one first support roller 234, the pusher block 232 is supported on the storage shaft 22 by that single first support roller 234. When there are multiple first support rollers 234, the pusher block 232 is supported on the storage shaft 22 by all the first support rollers 234. The number of first support rollers 234 can be set according to the size of the storage shaft 22, as long as it can reduce the frictional force generated by the axial movement of the pusher block 232 along the storage shaft 22, and is not limited here.

[0139] Specifically, in this embodiment, the material preparation mechanism 20 further includes a plurality of second support rollers (not shown) that are rotatably connected to the storage shaft 22. These second support rollers are spaced apart along the axial direction of the storage shaft 22, and the spare material rolls A1 are supported on the storage shaft 22 by their corresponding second support rollers. Thus, when the pusher block 232 pushes each spare material roll A1, each spare material roll A1 moves axially along the storage shaft 22 under the rolling action of its corresponding second support roller, greatly reducing the thrust required to move each spare material roll A1 axially along the storage shaft 22, and further reducing the difficulty of pushing the material.

[0140] Please see Figure 18 , Figure 19 and Figure 21In the embodiments of this application, the unwinding mechanism 31 has an unwinding shaft 311 for loading a spare roll A1. The picking mechanism 43 includes the aforementioned picking shaft 431, a support 432, and a feeding unit 435. The support 432 is mounted on the driving end of the translation drive 411, enabling the translation drive 411 to drive the support 432 to move along the first direction X1. The picking shaft 431 and the feeding unit 435 are both mounted on the support 432, allowing the picking shaft 431 and the feeding unit 435 to move together with the support 432. Under the driving action of the translation drive 411, the support 432 can drive the picking shaft 431 to move along the first direction X1 to axially align with the storage shaft 22, so that the pushing assembly 23 can push the spare roll A1 on the storage shaft 22 onto the picking shaft 431. Driven by the translation drive 411, the support 432 can also move the take-up shaft 431 to axially align with the unwinding shaft 311. At this time, the feeding unit 435 can controllably push the spare roll A1 on the take-up shaft 431 axially onto the unwinding shaft 311, thereby realizing the transfer of the spare roll A1 from the storage shaft 22 to the unwinding shaft 311.

[0141] In a specific embodiment, the material handling mechanism 43 further includes a third mounting base 433 and a fourth driving member 434. The third mounting base 433 is movably connected to the support base 432 along a third direction X3. The fourth driving member 434 is mounted on the support base 432, and the driving end of the fourth driving member 434 is connected to the third mounting base 433, enabling the fourth driving member 434 to drive the third mounting base 433 to move relative to the support base 432 along a third direction X3. A material handling shaft 431 is mounted on the third mounting base 433, enabling the material handling shaft 431 to move together with the third mounting base 433. The axial direction of the material handling shaft 431 is aligned with the third direction X3.

[0142] The translation drive 411 of the drive assembly 41 drives the carrier 432 to move along the first direction X1, thereby causing the take-up shaft 431 to move along the first direction X1, so that the take-up shaft 431 moves along the first direction X1 to be opposite to the storage shaft 22 or the unwinding shaft 311 in the third direction X3. The fourth drive 434 drives the third mounting base 433 to move along the third direction X3, thereby causing the take-up shaft 431 to move along the third direction X3, so that the take-up shaft 431 moves along the third direction X3 to be axially connected to or separated from the storage shaft 22 or the unwinding shaft 311.

[0143] It should be noted that the material roll (i.e., the working material roll or the spare material roll A1) includes a drum A5 and the strip wound on the drum A5. After the spare material roll A1 on the unwinding shaft 311 of the unwinding mechanism 31 is switched to the working material roll, the unwinding shaft 311 of the unwinding mechanism 31 drives the working material roll to rotate and unwind the working strip downstream. When the working material roll on the unwinding shaft 311 is unwound, the tape receiving assembly 32 cuts off the passing working strip and spare strip A2. The unwinding shaft 311 of the unwinding mechanism 31 drives the drum A5 on it to rotate in the opposite direction until the upstream cut end of the working strip is wound onto the drum A5. At this time, the drum A5 on the unwinding shaft 311 needs to be unloaded from the unwinding shaft 311 and transferred to a designated position.

[0144] To unload the drum A5 from the unwinding shaft 311, in some embodiments, the translation drive 411 of the drive assembly 41 can drive the carrier 432 to move along a first direction X1 to the unwinding shaft 311, so that the take-up shaft 431 and the unwinding shaft 311 are opposite each other in a third direction X3. The fourth drive 434 can drive the third mounting base 433 to move along a third direction X3, thereby causing the take-up shaft 431 to axially engage with the unwinding shaft 311. The feeding unit 435 can controllably clamp the drum A5 on the unwinding shaft 311 and move the drum A5 axially to the take-up shaft 431, thereby realizing the transfer of the drum A5 from the unwinding shaft 311 to the take-up shaft 431.

[0145] It should be noted that in this embodiment, the feeding unit 435 pushes the spare material roll A1 on the take-up shaft 431 along the third direction X3 to the unwind shaft 311. The feeding unit 435 clamps the material cylinder A5 on the unwind shaft 311 and moves the material cylinder A5 along the third direction X3 to the take-up shaft 431. Compared with the scheme of pushing the material cylinder A5 on the unwind shaft 311 to the take-up shaft 431, the method of using the feeding unit 435 to clamp the material cylinder A5 in this embodiment can reduce the stroke of the feeding unit 435, thereby saving space, especially the space in the third direction X3.

[0146] It should be noted that the material cylinder A5 on the unwinding shaft 311 is not limited to being transferred to the take-up shaft 431 by the feeding unit 435. In other embodiments, after the feeding unit 435 clamps the material cylinder A5 on the unwinding shaft 311 and drives the material cylinder A5 axially away from the unwinding shaft 311, the material cylinder A5 is not sleeved on the take-up shaft 431, but is clamped and fixed by the feeding unit 435. For ease of understanding, this article uses the implementation method of transferring the material cylinder A5 on the unwinding shaft 311 to the take-up shaft 431 by the feeding unit 435 as an example for explanation.

[0147] Specifically, in this embodiment, the feeding unit 435 includes a fifth driving member 4351, a fourth mounting base 4352, and a clamping part 4353. The fifth driving member 4351 is mounted on the support base 432, allowing the fifth driving member 4351 to move together with the support base 432. The fourth mounting base 4352 is mounted on the driving end of the fifth driving member 4351, and the fifth driving member 4351 drives the fourth mounting base 4352 to move along a third direction X3. The clamping part 4353 is mounted on the fourth mounting base 4352, allowing the clamping part 4353 to move together with the fourth mounting base 4352. It should be noted that the fifth driving member 4351 can be a linear drive module such as an electric cylinder or a pneumatic cylinder, and is not limited here.

[0148] Thus, when it is necessary to push the spare roll A1 on the take-up shaft 431 onto the unwinding shaft 311, the clamping part 4353 is located at the end of the spare roll A1 away from the unwinding shaft 311. The fifth drive member 4351 drives the fourth mounting base 4352 to move along the third direction X3, thereby driving the clamping part 4353 to push the spare roll A1 on the take-up shaft 431 toward the unwinding shaft 311 along the third direction X3 until the spare roll A1 is pushed onto the unwinding shaft 311.

[0149] When it is necessary to push the drum A5 on the unwinding shaft 311 onto the take-up shaft 431, the fifth drive member 4351 drives the fourth mounting base 4352 to move towards the unwinding shaft 311 along the third direction X3, thereby causing the clamping part 4353 to move along the third direction X3 to the drum A5 on the unwinding shaft 311. Then, the clamping part 4353 clamps the drum A5 on the unwinding shaft 311. Then, the fifth drive member 4351 drives the fourth mounting base 4352 to move towards the take-up shaft 431 along the third direction X3, thereby causing the clamping part 4353 to move along the third direction X3 to the take-up shaft 431. Since the clamping part 4353 clamps the drum A5, the drum A5 also moves from the unwinding shaft 311 onto the take-up shaft 431 along with the clamping part 4353.

[0150] Specifically, the clamping part 4353 includes a gripper drive c1 and two grippers c2. The gripper drive c1 is mounted on the fourth mounting base 4352, allowing it to move along with the fourth mounting base 4352. The two grippers c2 are respectively mounted on the two driving ends of the gripper drive c1, and a clamping space is formed between the two grippers c2 for the material take-up shaft 431 or the unwinding shaft 311 to pass through. The gripper drive c1 is used to drive the two grippers c2 to clamp or release the material cylinder A5 on the unwinding shaft 311. Optionally, the gripper drive c1 can be a gripper cylinder.

[0151] Thus, when it is necessary to push the spare roll A1 on the take-up shaft 431 onto the unwinding shaft 311, the two grippers c2 are located at the end of the spare roll A1 away from the unwinding shaft 311, and the gripper drive member c1 drives the two grippers c2 to move closer to each other, so that the two grippers c2 can abut against the end of the spare roll A1. Then, the fifth drive member 4351 drives the fourth mounting base 4352 to move closer to the unwinding shaft 311 along the third direction X3, thereby driving the two grippers c2 to push the spare roll A1 on the take-up shaft 431 toward the unwinding shaft 311 along the third direction X3 until the spare roll A1 is pushed onto the unwinding shaft 311.

[0152] When the drum A5 on the unwinding shaft 311 needs to be pushed onto the take-up shaft 431, the gripper drive c1 drives the two grippers c2 to move away from each other, making the clamping space between the two grippers c2 wide enough for the drum A5 on the unwinding shaft 311 to enter. Then, the fifth drive 4351 drives the fourth mounting base 4352 to move closer to the unwinding shaft 311 along the third direction X3, thereby moving the two grippers c2 along the third direction X3 to the drum A5 on the unwinding shaft 311. At this time, the drum A5 on the unwinding shaft 311 is located between the two grippers c2. Then, the gripper drive c1 controls the two grippers c2 to move closer to each other until the drum A5 on the unwinding shaft 311 is clamped. Then, the fifth drive unit 4351 drives the fourth mounting base 4352 to move along the third direction X3 towards the take-up shaft 431, thereby driving the two grippers c2 to move along the third direction X3 to the take-up shaft 431. Since the two grippers c2 clamp the material cylinder A5, the material cylinder A5 also moves from the unwinding shaft 311 to the take-up shaft 431 along with the two grippers c2.

[0153] Please see Figure 1 , Figure 23 and Figure 24In an embodiment of this application, the roll changing device further includes an unloading mechanism 60, which includes a guide 61 and a storage container 62. The two longitudinal ends of the guide 61 are a feed end d1 and a connecting end d2, respectively. The guide 61 is connected to the storage container 62 through the connecting end d2. Under the driving action of the translation drive 411 of the drive assembly 41, the support 432 can drive the take-up shaft 431 to move to the feed end d1. The feeding unit 435 can controllably push the cylinder A5 on the take-up shaft 431 axially away from the take-up shaft 431 and fall into the feed end d1 of the guide 61. The guide 61 is configured to guide the cylinder A5 at the feed end d1 to roll toward the connecting end d2 and reach the storage container 62. Thus, after the material cylinder A5 is transferred from the unwinding shaft 311 to the take-up shaft 431, firstly, the translation drive 411 drives the carrier 432 to move along the first direction X1 towards the guide 61 until the take-up shaft 431 reaches above the feed end d1 of the guide 61. Then, the fifth drive 4351 drives the fourth mounting base 4352 to move along the third direction X3, thereby causing the two grippers c2 to push the material cylinder A5 away from the take-up shaft 431 along the third direction X3, so that the material cylinder A5 falls into the feed end d1 of the guide 61. The material cylinder A5, which has fallen into the feed end d1 of the guide 61, rolls along the guide 61 towards the connecting end d2 until the material cylinder A5 reaches the storage unit 62 for storage.

[0154] Specifically, in this embodiment, the guide member 61 has a guide groove 612 extending longitudinally from the feed end d1 to the connecting end d2. This guide groove 612 is used to receive the material cylinder A5 and guide it to roll from the feed end d1 to the connecting end d2. Thus, by using the guide groove 612 to receive and guide the material cylinder A5 into the storage member 62, the risk of the material cylinder A5 falling off the guide member 61 is effectively reduced.

[0155] Furthermore, the storage unit 62 has a storage trough 622 for receiving the material cylinder A5. The unloading mechanism 60 also includes a seventh drive member 641 and a pusher block 642. The pusher block 642 is mounted on the drive end of the seventh drive member 641 and is located at the end of the storage unit 62 near the guide member 61. Under the driving action of the seventh drive member 641, the pusher block 642 can push the material cylinder A5 in the storage trough 622 to the end away from the guide member 61. Thus, when the material cylinder A5 rolls from the guide groove 612 on the guide member 61 into the storage trough 622 of the storage unit 62, the seventh drive member 641 drives the pusher block 642 to move along the storage trough 622, thereby pushing the material cylinder A5 in the storage trough 622 to the end of the storage trough 622 away from the guide member 61. When the material cylinder A5 in the storage trough 622 is full, the material cylinder A5 in the storage trough 622 can be transferred manually or by handling equipment. Alternatively, the seventh drive unit 641 may be a cylinder.

[0156] It should be noted that, in order to shorten the stroke of the picking mechanism 43, in some embodiments, the unloading mechanism 60 is set as close as possible to the preparation mechanism 20, so that the position where the picking shaft 431 of the picking mechanism 43 unloads the material cylinder A5 at the unloading mechanism 60 is close to or the same position where the picking shaft 431 of the picking mechanism 43 transfers the spare material roll A1 at the preparation mechanism 20. This greatly shortens the stroke of the picking mechanism 43, makes the roll changing device structure more compact, and improves space utilization.

[0157] Because the unloading mechanism 60 and the preparation mechanism 20 are close together, when the picking mechanism 43 moves to the preparation mechanism 20 to transfer the spare material belt A2, the feeding end d1 of the guide 61 is prone to interference with the picking mechanism 43. To avoid interference between the feeding end d1 of the guide 61 and the picking mechanism 43, in some embodiments, the guide 61 is configured to rotate around its connecting end d2 to a receiving position and a clearance position. When the guide 61 rotates to the receiving position, the feeding end d1 can receive the material cylinder A5 pushed away from the picking shaft 431 by the feeding unit 435. When the guide 61 rotates to the clearance position, the feeding end d1 allows the picking shaft 431 of the picking mechanism 43 to axially align with the storage shaft 22, thereby avoiding interference between the guide 61 and the picking shaft 431 of the picking mechanism 43.

[0158] Furthermore, the unloading mechanism 60 also includes a fifth mounting base 65 and a sixth drive member 63. The storage member 62 is fixedly connected to the fifth mounting base 65. The connecting end d2 of the guide member 61 is rotatably connected to the fifth mounting base 65. The sixth drive member 63 includes a drive member body 631 and a telescopic end 632 that can be controllably extended or retracted relative to the drive member body 631. The drive member body 631 is hinged to the fifth mounting base 65, and the telescopic end 632 is hinged to the guide member 61, thereby driving the guide member 61 to rotate between a receiving position and a clearance position by extending and retracting the telescopic end 632 relative to the drive member body 631. Optionally, the sixth drive member 63 can be a cylinder.

[0159] Optionally, when the telescopic end 632 extends relative to the drive body 631, it can drive the guide 61 to rotate to a clearance position, so that the picking shaft 431 of the picking mechanism 43 can smoothly transfer the spare material roll A1 at the material preparation mechanism 20. When the telescopic end 632 retracts relative to the drive body 631, it can drive the guide 61 to rotate to a receiving position, so that the material cylinder A5 on the picking shaft 431 of the picking mechanism 43 can smoothly fall into the feeding end d1 of the guide 61.

[0160] Please see Figure 1 , Figure 7 , Figure 9 and Figure 10 In embodiments of this application, the rewinding device further includes a device for receiving waste roll A4 (see...). Figure 10) waste bin 50 (see Figure 1 The drive assembly 41 also includes a waste removal assembly 44 mounted on the drive end of the drive assembly 41. The drive assembly 41 further drives the waste removal assembly 44 to move to the receiving roller 331 of the waste receiving assembly 33 and to the waste container 50. When the drive assembly 41 drives the waste removal assembly 44 to the receiving roller 331 of the waste receiving assembly 33, the waste removal assembly 44 can remove the waste roll A4 from the receiving roller 331 of the waste receiving assembly 33. When the drive assembly 41 drives the waste removal assembly 44 to the waste container 50, the waste removal assembly 44 can release the waste roll A4 into the waste container 50. It should be noted that the movement of the waste removal assembly 44 is not limited to using the drive assembly 41 to drive it. In other embodiments, a separate drive component can be configured for the waste removal assembly 44, and this drive component can be used to drive the waste removal assembly 44 to move, as long as the transfer of the waste roll A4 can be achieved. This is not limited here.

[0161] Specifically, the waste removal component 44 is mounted on the second transfer seat 415 of the drive component 41, so that the waste removal component 44 can move together with the second transfer seat 415 along the first direction X1 and the second direction X2, ensuring that the waste removal component 44 can accurately move to the receiving roller 331 of the waste receiving component 33 or the waste box 50.

[0162] Specifically, in this embodiment, the waste removal assembly 44 includes a second moving seat 443, a first clamping block 4453, and a second clamping block 4455. The second moving seat 443 is mounted on a second transfer seat 415 to move together with the second transfer seat 415. The first clamping block 4453 and the second clamping block 4455 are disposed on the second moving seat 443 to move together with the second moving seat 443. A receiving space j is formed between the first clamping block 4453 and the second clamping block 4455 for the receiving roller 331 to enter. The first clamping block 4453 and the second clamping block 4455 are configured to controllably move closer to or further away from each other to clamp or release the waste roll A4. A support portion 4459 and a pushing portion 4457 are provided on the sides of the first clamping block 4453 and the second clamping block 4455 facing each other. The second moving seat 443 is configured to move controllably along the axial direction of the take-up roller 331, thereby driving each pusher part 4457 to push the waste roll A4 on the take-up roller 331 axially and detach it from the take-up roller 331, and then enter the receiving space j. Each support part 4459 is used to support the waste roll A4 that has detached from the take-up roller 331 and is located in the receiving space j.

[0163] Thus, when it is necessary to remove the waste roll A4 from the take-up roller 331, firstly, the third transfer seat 416 drives the second moving seat 443 to move along the first direction X1 and / or the second direction X2 to the waste removal position, so that the receiving space j between the take-up roller 331 of the waste collection assembly 33 and the first clamping block 4453 and the second clamping block 4455 is opposite in the third direction X3. Then, the second moving seat 443 drives the first clamping block 4453 and the second clamping block 4455 to move closer to the take-up roller 331 along the third direction X3, so that the take-up roller 331 and the waste roll A4 on it enter the receiving space j between the first clamping block 4453 and the second clamping block 4455, until the pushing part 4457 on the first clamping block 4453 and the pushing part 4457 on the second clamping block 4455 reach the end of the waste roll A4 away from the second moving seat 443. Then, the first clamping block 4453 and the second clamping block 4455 are brought closer together until the pushing part 4457 on the first clamping block 4453 and the pushing part 4457 on the second clamping block 4455 can abut against the end face of the waste roll A4 away from the second moving seat 443. Next, the second moving seat 443 moves away from the take-up roller 331 along a third direction X3, thereby driving the pushing part 4457 to push the waste roll A4 on the take-up roller 331 axially until the waste roll A4 is disengaged from the take-up roller 331 and supported by the various support parts 4459 between the first clamping block 4453 and the second clamping block 4455. Then, the first clamping block 4453 and the second clamping block 4455 continue to move closer together to clamp the waste roll A4, thereby preventing the waste roll A4 from loosening. Next, the third transfer seat 416 moves the second moving seat 443 along the first direction X1 and / or the second direction X2 to the waste disposal position, so that the first clamping block 4453 and the second clamping block 4455 are positioned above the waste box 50. Finally, the first clamping block 4453 and the second clamping block 4455 move away from each other until the waste roll A4 between the first clamping block 4453 and the second clamping block 4455 falls into the waste box 50.

[0164] Furthermore, the first clamping block 4453 is provided with multiple support portions 4459, which are spaced apart along the axial direction of the take-up roller 331. The second clamping block 4455 is provided with multiple support portions 4459, which are spaced apart along the axial direction of the take-up roller 331. In this way, the support portions 4459 on the first clamping block 4453 and the multiple support portions 4459 on the second clamping block 4455 work together to support the waste roll A4 entering the receiving space j, preventing the waste roll A4 from falling off.

[0165] Furthermore, in the arrangement direction of the first clamping block 4453 and the second clamping block 4455, the support portions 4459 on the first clamping block 4453 and the support portions 4459 on the second clamping block 4455 are staggered, so that when the first clamping block 4453 and the second clamping block 4455 are close to each other to clamp the waste roll A4, the support portions 4459 on the first clamping block 4453 and the support portions 4459 on the second clamping block 4455 are avoided from colliding.

[0166] It should be noted that the support portion 4459 on the first clamping block 4453 and the second clamping block 4455 is not essential. In some embodiments, the support portion 4459 may not be provided on the first clamping block 4453 and the second clamping block 4455. The waste roll A4, which has detached from the take-up roller 331 and entered the receiving space j, is directly clamped and fixed by the first clamping block 4453 and the second clamping block 4455. In still other embodiments, the support portion 4459 is not provided on the first clamping block 4453 and the second clamping block 4455 either. The first clamping block 4453 and the second clamping block 4455 are arranged vertically such that the waste roll A4, which has detached from the take-up roller 331 and entered the receiving space j, is supported on the lower one of the first clamping block 4453 and the second clamping block 4455. For ease of understanding, this article uses an embodiment in which both the first clamping block 4453 and the second clamping block 4455 are provided as an example for explanation.

[0167] Furthermore, each pusher portion 4457 includes a second elastic element (not shown) and a pusher post (not indicated). Mounting holes are provided on the sides of the first clamping block 4453 and the second clamping block 4455 facing each other. A portion of the pusher post passes through the corresponding mounting hole, while another portion is located in the space between the first clamping block 4453 and the second clamping block 4455, and the pusher post is axially movable along the mounting hole. The second elastic element is disposed within the corresponding mounting hole and abuts against the portion of the pusher post located within the mounting hole, providing a preload force that causes the pusher post to tend to move outward from the mounting hole. Thus, when the first clamping block 4453 and the second clamping block 4455 approach each other and clamp the waste roll A4, even if the pusher post on the first clamping block 4453 and the pusher post on the second clamping block 4455 abut against each other, the elasticity of the second elastic element prevents damage and does not interfere with the clamping action of the first clamping block 4453 and the second clamping block 4455. Similarly, when the first clamping block 4453 and the second clamping block 4455 approach each other and clamp the waste roll A4, even if the pusher on the first clamping block 4453 abuts against the second clamping block 4455, or even if the pusher on the second clamping block 4455 abuts against the first clamping block 4453, the second elastic element is elastic, so it will not cause damage or interfere with the clamping action of the first clamping block 4453 and the second clamping block 4455. Optionally, the pusher part 4457 can be a spring plunger. The spring plunger is a standard part, which helps to reduce equipment costs.

[0168] Specifically, in this embodiment, the waste removal assembly 44 further includes a sixth mounting base 441 and an eighth driving member 442. The sixth mounting base 441 is mounted on the driving end of the driving assembly 41, enabling the driving assembly 41 to drive the sixth mounting base 441 to move along a first direction X1 and / or a second direction X2. A second moving seat 443 is movably connected to the sixth mounting base 441 along a third direction X3. The eighth driving member 442 is mounted on the sixth mounting base 441, and its driving end is connected to the second moving seat 443, enabling the eighth driving member 442 to drive the second moving seat 443 to move relative to the sixth mounting base 441 along a third direction X3. The third direction X3 is aligned with the axial direction of the receiving roller 331.

[0169] Specifically, the sixth mounting base 441 is mounted on the second transfer base 415 of the drive assembly 41, so that the sixth mounting base 441 can move together with the second transfer base 415 along the first direction X1, the second direction X2 and the third direction X3.

[0170] Thus, the second transfer seat 415 drives the sixth mounting seat 441 to move along the first direction X1, the second direction X2, and / or the third direction X3, thereby moving the first clamping block 4453 and the second clamping block 4455 to the receiving roller 331 or the waste box 50. When the first clamping block 4453 and the second clamping block 4455 move to the receiving roller 331, the eighth driving member 442 drives the second moving seat 443 to move along the third direction X3, so that the receiving roller 331 first enters and then exits between the first clamping block 4453 and the second clamping block 4455, thereby causing the waste roll A4 on the receiving roller 331 to separate from the receiving roller 331 under the pushing action of the pushing part 4457.

[0171] Based on the aforementioned rewinding device, this application also provides a winding apparatus, which includes a winding device and a rewinding device as described in any of the above embodiments. The rewinding device is used to unwind the working strip output from the winding device, and the winding device is used to wind the working strip output from the rewinding device to form a battery cell. It should be noted that the working strip can be a positive electrode sheet or a negative electrode sheet, and of course, it can also be other types of strips, which are not limited here.

[0172] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0173] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application.
