Description

Technical Field

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

[0002] In the lithium battery manufacturing process, cathode sheets, separators, and anode sheets need to be wound together to form a battery cell. Generally, separators are supplied to the winding equipment via unwinding from a separator roll. When a separator roll is used up, a new separator roll needs to be replaced. The roll currently supplying separators to the winding equipment is the working roll, and the separator supplied by the working roll is called the working strip. The separator roll ready to replace the working roll is the spare roll, and the separator on the spare roll is called the spare strip.

[0003] Traditionally, a roll-changing device is needed to switch between the spare roll and the working roll. This involves replacing the working roll with the spare roll and connecting the start end of the spare strip to the end of the working strip, thus making the spare roll the new working roll and continuing to supply working strip to the winding machine. However, to achieve a smooth connection between the working and spare strips, manual labor is required to pull the start end of the strip on the spare roll to the designated position. This results in low automation of the roll-changing device, necessitates personnel on-site, increases labor costs, and reduces production efficiency. Utility Model Content

[0004] Therefore, it is necessary to provide a highly automated starting mechanism, winding device, and winding machine that can improve production efficiency and reduce labor costs to address the above problems.

[0023] In some embodiments, the initiator assembly is movably connected to the drive end of the drive assembly along the arrangement direction of the two adsorption surfaces.

[0024] The starting processing mechanism also includes a buffer elastic element, which is connected to the drive end of the drive assembly and the starting assembly.

[0025] In some embodiments, the cushioning elastic element is a cylinder or a spring.

[0026] A roll changing device includes a glue supply mechanism, an unwinding mechanism, a tape splicing mechanism, and a starting processing mechanism as described in any of the above embodiments, wherein the unwinding mechanism is arranged upstream of the tape splicing mechanism.

[0027] In some embodiments, the adhesive supply mechanism includes an adhesive tape unwinding assembly, an adhesive clamping assembly, an adhesive cutting assembly, and an adhesive pulling assembly;

[0028] The adhesive clamping assembly is arranged downstream of the tape unwinding assembly, the adhesive pulling assembly is arranged at intervals with the adhesive clamping assembly, and the adhesive cutting assembly is arranged on the side of the adhesive clamping assembly facing the adhesive clamping assembly.

[0037] In actual use, the aforementioned starting mechanism, roll changing device, and winding machine are operated by a drive assembly that moves the starting assembly to the glue supply mechanism, allowing the tape supplied by the glue supply mechanism to enter between the first and second clamping members. Driven by the clamping drive assembly, the first and second clamping members clamp the tape, with both ends of the tape hanging down onto two adsorption surfaces, where they are then adsorbed and fixed. When the tape on the working roll is almost unwound, the unwinding assembly containing the working roll stops unwinding, and the tape receiving mechanism cuts the passing working tape and adsorbs and fixes the downstream cut end of the working tape. Then, the drive assembly moves the starting assembly to the unwinding assembly containing the spare roll, causing one adsorption surface of the second clamping member to abut against the starting end of the tape on the spare roll, thus bonding the tape on that adsorption surface to the starting end of the tape on the spare roll. Then, the drive assembly moves the starting assembly to the tape-joining mechanism, causing another adsorption surface of the second clamping member to abut against the downstream cut end of the working tape fixed on the tape-joining mechanism, thus bonding the tape on this adsorption surface to the downstream cut end of the working tape. At this time, the starting end of the spare tape and the downstream cut end of the working tape are bonded together by the same tape, thus achieving tape joining between the spare tape and the working tape. Under the driving action of the clamping drive assembly, the first and second clamping members release the tape and move away from the tape-joining mechanism under the driving action of the drive assembly. At this time, the spare roll is switched to the working roll, and the working tape continues to be unwound and output downstream, thus achieving automatic roll changing.

[0038] In this way, the aforementioned roll changing device automatically picks up and lifts the starting end of the material strip on the spare roll through the starting component, and then the auxiliary tape connecting mechanism completes the tape connecting action between the working material strip and the spare material strip. This helps to simplify the equipment structure, improve the automation level of the equipment, reduce labor costs, and improve production efficiency. Attached Figure Description

[0054] Please see Figures 1 to 3 One embodiment of this application provides a roll changing device, including a starting processing mechanism 10, an adhesive supply mechanism 20, an unwinding mechanism (not shown in the figure), and a tape splicing mechanism 40. The adhesive supply mechanism 20 is used to supply adhesive tape to the starting processing mechanism 10. The unwinding mechanism has two unwinding assemblies 31. The rolls loaded on the two unwinding assemblies 31 can be alternately used as working roll A1 and spare roll A2, respectively. That is, when one unwinding assembly 31 is loaded with working roll A1, the other unwinding assembly 31 is loaded with spare roll A2. The unwinding assembly 31 loaded with working roll A1 drives the working roll A1 to the downstream tape splicing mechanism 40 to unwind working tape A3. The tape splicing mechanism 40 is used to cut the passing working tape A3 and to adsorb and fix the downstream cut end A31 of the working tape A3. The starting processing mechanism 10 is used to pick up the tape provided by the adhesive supply mechanism 20 and can move to abut against the spare roll A2 on the unwinding assembly 31, so that the starting processing mechanism 10 picks up the starting end A41 of the tape on the spare roll A2 through the tape. After the starting end A41 of the tape on the spare roll A2 is bonded to the tape, the starting processing mechanism 10 then pulls the starting end A41 of the tape to the tape joining mechanism 40, so that the downstream cut end A31 of the working tape A3 adsorbed by the tape joining mechanism 40 is also bonded to the tape, thereby realizing the bonding of the starting end A41 of the spare tape A4 and the downstream cut end A31 of the working tape A3 through the tape, that is, the tape joining is realized.

[0055] In this embodiment, the starting processing mechanism 10 includes a drive assembly 13 and a starting assembly 11 mounted on the drive end of the drive assembly 13. The drive assembly 13 drives the starting assembly 11 to move between the glue supply mechanism 20, the unwinding assembly 31, and the tape splicing mechanism 40. The starting assembly 11 includes a clamping drive member 111, a first clamping member 112, and a second clamping member 113. The first clamping member 112 and the second clamping member 113 are arranged opposite to each other, forming a clamping space between them for clamping the tape. At least one of the first clamping member 112 and the second clamping member 113 is connected to the drive end of the clamping drive member 111, so that the clamping drive member 111 can drive the first clamping member 112 and the second clamping member 113 to clamp or release the tape between them. The second clamping member 113 has adsorption surfaces B on both sides. When the tape is clamped between the first clamping member 112 and the second clamping member 113, the two ends of the tape hang down onto the two adsorption surfaces B of the second clamping member 113, so that the two adsorption surfaces B of the second clamping member 113 adsorb and fix the two ends of the tape respectively.

[0056] In actual use, the aforementioned roll-changing device involves the drive assembly 13 driving the starting assembly 11 to move to the glue supply mechanism 20, allowing the tape supplied by the glue supply mechanism 20 to enter between the first clamping member 112 and the second clamping member 113. Under the driving action of the clamping drive assembly 111, the first clamping member 112 and the second clamping member 113 clamp the tape, with both ends of the tape hanging down onto the two adsorption surfaces B, whereby they are adsorbed and fixed. When the tape on the working roll A1 is almost unwound, the unwinding assembly 31 containing the working roll A1 stops unwinding, and the tape receiving mechanism 40 cuts the passing working tape A3 and adsorbs and fixes the downstream cut end A31 of the working tape A3. Then, the drive assembly 13 drives the starting assembly 11 to move to the unwinding assembly 31, which contains the spare roll A2, so that one adsorption surface B of the second clamping member 113 abuts against the starting end A41 of the strip on the spare roll A2, thereby bonding the tape on the adsorption surface B to the starting end A41 of the strip on the spare roll A2. Next, the drive assembly 13 drives the starting assembly 11 to move to the tape-joining mechanism 40, so that the other adsorption surface B of the second clamping member 113 abuts against the downstream cut end A31 of the working strip A3, which is adsorbed and fixed on the tape-joining mechanism 40, thereby bonding the tape on the adsorption surface B to the downstream cut end A31 of the working strip A3. At this point, the starting end A41 of the spare strip A4 and the downstream cut end A31 of the working strip A3 are bonded together by the same tape, thus achieving the joining of the spare strip A4 and the working strip A3. Under the driving action of the clamping drive 111, the first clamping member 112 and the second clamping member 113 release the tape and move away from the tape receiving mechanism 40 under the driving action of the drive assembly 13. At this time, the spare material roll A2 is switched to the working material roll A1, and the working material tape A3 continues to be unwound and output downstream, thus realizing automatic roll changing.

[0057] Thus, the aforementioned roll changing device automatically picks up and lifts the starting end A41 of the material strip on the spare roll A2 through the starting component 11, and then the auxiliary tape connecting mechanism 40 completes the tape connecting action between the working material strip A3 and the spare material strip A4. This helps to simplify the equipment structure, improve the automation level of the equipment, reduce labor costs, and improve production efficiency.

[0058] It should be noted that the two adsorption surfaces B of the second clamping member 113 can adsorb and fix the tape using negative pressure adsorption. Specifically, multiple holes are formed on the adsorption surface B, and each hole is connected to an external negative pressure source through a pipe. When the tape needs to be adsorbed, the external negative pressure source evacuates air, thereby creating negative pressure in each hole, which in turn adsorbs the tape onto the adsorption surface B. When the tape is no longer needed, the external negative pressure source stops evacuating the vacuum, causing the vacuum in each hole to break, thereby releasing the adsorption of the tape. The number and arrangement of the holes on the adsorption surface B are not limited here, as long as they can achieve the adsorption and fixation of the tape.

[0059] It should be noted that the adhesive tape provided by the adhesive supply mechanism 20 can be divided into a first segment and two second segments, with the two second segments respectively connected to both ends of the first segment. When the starting assembly 11 picks up the adhesive, the first segment of the adhesive tape is clamped and fixed by the first clamping member 112 and the second clamping member 113, and the two adsorption surfaces B on the second clamping member 113 respectively adsorb and fix the two second segments of the adhesive tape.

[0060] In the embodiments of this application, the adhesive supply mechanism 20 includes an unwinding assembly 21, a clamping assembly 22, a cutting assembly 23, and a pulling assembly 24. The unwinding assembly 21 unwinds adhesive tape into the clamping assembly 22, which clamps or releases the passing adhesive tape. The pulling assembly 24 is spaced apart from the clamping assembly 22 along a first direction X. The pulling assembly 24 clamps the adhesive tape at the clamping assembly 22 and pulls out a certain length of adhesive tape along the first direction X. The cutting assembly 23 is arranged on the side of the clamping assembly 22 facing it and cuts the passing adhesive tape. The portion of the adhesive tape that is cut and located between the pulling assembly 24 and the cutting assembly 23 is the aforementioned adhesive tape. Thus, when adhesive needs to be taken, the pulling assembly 24 moves closer to the clamping assembly 22 until it clamps the starting end of the adhesive tape. Then, the clamping assembly 22 releases the passing tape, and the pulling assembly 24 moves away from the clamping assembly 22 until a certain length of tape is pulled out. At this time, the clamping assembly 22 clamps the passing tape again. The driving assembly 13 drives the starting assembly 11 to move to the position between the cutting assembly 23 and the pulling assembly 24, so that the tape between the cutting assembly 23 and the pulling assembly 24 enters between the first clamping member 112 and the second clamping member 113. Then, the clamping drive 111 drives the first clamping member 112 and the second clamping member 113 to clamp the tape between them. Then, the cutting assembly 23 cuts the passing tape, and the pulling assembly 24 releases the tape. At this time, the cut tape is clamped and fixed between the first clamping member 112 and the second clamping member 113, thus realizing the removal of the tape.

[0061] Please see Figure 1 , Figures 4 to 6Specifically, in this embodiment, the starting processing mechanism 10 further includes a smoothing component 15, which includes a mounting base 151 and a first smoothing member 152 and a second smoothing member 153, both mounted on the mounting base 151. A smoothing channel is formed between the first smoothing member 152 and the second smoothing member 153. Under the driving action of the driving component 13, the first clamping member 112 and the second clamping member 113 of the starting component 11 pass sequentially through the smoothing channel between the first smoothing member 152 and the second smoothing member 153. During the process of the second clamping member 113 passing through the smoothing channel, the first smoothing member 152 and the second smoothing member 153 respectively abut against the two adsorption surfaces B on the second clamping member 113, thereby flattening the two second segments of the tape onto the two adsorption surfaces B, ensuring that the two adsorption surfaces B respectively adsorb and fix the two second segments of the tape.

[0062] Specifically, in the embodiment, the smoothing component 15 is arranged above the space between the tape cutting component 23 and the tape pulling component 24, so that after the starting component 11 uses the first clamping member 112 and the second clamping member 113 to clamp the tape, during the process of the driving component 13 driving the starting component 11 to move upward, the first clamping member 112 and the second clamping member 113 can pass through the smoothing channel between the first smoothing member 152 and the second smoothing member 153 in sequence, ensuring that the two second segments of the tape are flattened onto the two adsorption surfaces B under the action of the first smoothing member 152 and the second smoothing member 153, thereby ensuring that the two adsorption surfaces B of the second clamping member 113 adsorb and fix the two second segments of the tape respectively.

[0063] In some embodiments, the first smoothing member 152 and the second smoothing member 153 can be flattening plates. When the second clamping member 113 passes through the smoothing channel, the flattening plate is used to flatten the second section of the tape onto the adsorption surface B. In this way, the second section of the tape is smoothed using a flattening plate, which has a simple structure and low cost.

[0064] Of course, in other embodiments, the first smoothing member 152 and the second smoothing member 153 may also be smoothing rollers. When the second clamping member 113 passes through the smoothing channel, the smoothing rollers are used to roll the second section of the tape onto the adsorption surface B. As long as the second section of the tape can be smoothed onto the adsorption surface B, it is not limited here. In some other embodiments, one of the first smoothing member 152 and the second smoothing member 153 may be a smoothing plate and the other may be a smoothing roller. As long as the two second sections of the tape can be smoothed onto the two adsorption surfaces B respectively, it is not limited here.

[0065] In a specific embodiment, the smoothing component 15 further includes a first motion seat 154, a second motion seat 155, and a first elastic member 156. Both the first motion seat 154 and the second motion seat 155 are mounted on the mounting base 151. The first smoothing member 152 is mounted on the first motion seat 154, and the second smoothing member 153 is mounted on the second motion seat 155. The first motion seat 154 and the second motion seat 155 can move closer to or further away from each other, thereby causing the first smoothing member 152 and the second smoothing member 153 to move closer to or further away from each other. The two ends of the first elastic member 156 are respectively connected to the first motion seat 154 and the second motion seat 155, giving the first motion seat 154 and the second motion seat 155 an elastic force that tends to move closer to each other. Thus, when the first clamping member 112 and the second clamping member 113 pass through the smoothing channel, the first clamping member 112 and the second clamping member 113 use their respective strength to separate the first smoothing member 152 and the second smoothing member 153. This means that the first moving seat 154 and the second moving seat 155 overcome the elastic force provided by the first elastic member 156 and move away from each other (at this time, the stretching amount of the first elastic member 156 increases). When the first clamping member 112 and the second clamping member 113 leave the smoothing channel, under the elastic force provided by the first elastic member 156, the first moving seat 154 and the second moving seat 155 drive the first smoothing member 152 and the second smoothing member 153 to move closer together and reset. In other words, when the first clamping member 112 or the second clamping member 113 has not entered the smoothing channel, the distance between the first smoothing member 152 and the second smoothing member 153 is less than the width of the first clamping member 112 and the second clamping member 113, thereby ensuring that the first smoothing member 152 and the second smoothing member 153 respectively press against the two adsorption surfaces B of the second clamping member 113 during the process of the second clamping member 113 passing through the smoothing channel. Optionally, the first elastic member 156 can be a spring.

[0066] Furthermore, the smoothing component 15 also includes a limiting block 157 mounted on the mounting base 151. The limiting block 157 is located between the first moving base 154 and the second moving base 155, thereby limiting the minimum distance between the first moving base 154 and the second moving base 155, that is, limiting the minimum distance between the first smoothing component 152 and the second smoothing component 153, thereby preventing the first clamping component 112 from being unable to enter between the first smoothing component 152 and the second smoothing component 153 due to the distance between the first smoothing component 152 and the second smoothing component 153 being too small.

[0067] It should be noted that it is not limited to the first moving seat 154 and the second moving seat 155 both being able to move relative to the mounting seat 151. In other embodiments, one of the first moving seat 154 and the second moving seat 155 may be able to move relative to the mounting seat 151, while the other is fixed relative to the mounting seat 151. As long as it can be achieved that the first smoothing member 152 and the second smoothing member 153 press against the two adsorption surfaces B respectively when the second clamping member 113 passes through the smoothing channel, it is not limited here.

[0068] It should also be noted that the two ends of the first elastic member 156 are not limited to being connected to the first moving seat 154 and the second moving seat 155 respectively. In some other embodiments, the two ends of the first elastic member 156 may also be connected to the first smoothing member 152 and the second smoothing member 153 respectively, which is not limited here.

[0069] Specifically, in this embodiment, the first clamping member 112 has a first guide surface a1 and a second guide surface a2 on the side opposite to the second clamping member 113, and the arrangement direction of the first guide surface a1 and the second guide surface a2 is consistent with the arrangement direction of the two adsorption surfaces B. Figure 6 In the embodiment shown, the first clamping member 112 and the second clamping member 113 are arranged at intervals along the third direction Z. The two adsorption surfaces B are located on both sides of the second clamping member 113 in the first direction X. The length direction of the first clamping member 112 and the second clamping member 113 is the second direction Y. The first guide surface a1 and the second guide surface a2 are arranged along the first direction X. The two adsorption surfaces B are also arranged along the first direction X. The first smoothing member 152 and the second smoothing member 153 are also arranged along the first direction X. That is to say, the arrangement directions of the first guide surface a1 and the second guide surface a2, the arrangement directions of the two adsorption surfaces B, and the arrangement directions of the first smoothing member 152 and the second smoothing member 153 are all consistent.

[0070] In the direction from the first clamping member 112 to the second clamping member 113, the distance between the first guide surface a1 and the second guide surface a2 gradually increases. Thus, as the driving assembly 13 drives the starting assembly 11 into the smoothing channel along the third direction Z, the first smoothing member 152 and the second smoothing member 153 abut against the first guide surface a1 and the second guide surface a2, respectively. As the first clamping member 112 continues to enter the smoothing channel, the first smoothing member 152 and the second smoothing member 153 slide along the first guide surface a1 and the second guide surface a2, respectively. Because the distance between the first guide surface a1 and the second guide surface a2 gradually increases, the first smoothing member 152 and the second smoothing member 153 are gradually spread apart (i.e., the distance between them gradually increases), ensuring that when the second clamping member 113 enters the smoothing channel, the first smoothing member 152 and the second smoothing member 153 remain in contact with the two adsorption surfaces B, respectively. It should be noted that the first guide surface a1 and the second guide surface a2 can be either planes or curved surfaces, as long as they can achieve the guiding function, and no limitation is made here.

[0071] Please continue reading Figure 1 , Figure 3 and Figure 5 In some embodiments, the glue clamping assembly 22, glue pulling assembly 24 and glue cutting assembly 23 of the glue supply mechanism 20 are all mounted on the mounting base 151 of the smoothing assembly 15 to facilitate the assembly and disassembly of the glue supply mechanism 20 and the smoothing assembly 15.

[0072] Specifically, the adhesive clamping assembly 22 includes a first adhesive clamping drive and two first adhesive clamping blocks. The first adhesive clamping drive is mounted on the mounting base 151. The two first adhesive clamping blocks are respectively mounted on the two drive ends of the first adhesive clamping drive, which is used to drive the two first adhesive clamping blocks to clamp or release the passing adhesive tape. Optionally, the first adhesive clamping drive can be a gripper cylinder.

[0073] Specifically, the adhesive stretching assembly 24 includes an adhesive stretching drive 241, a movable base 242, a second adhesive clamping drive 243, and two second adhesive clamping blocks 244. The adhesive stretching drive 241 is mounted on the mounting base 151. The movable base 242 is movably connected to the mounting base 151 along a first direction X and is connected to the drive end of the adhesive stretching drive 241. The adhesive stretching drive 241 drives the movable base 242 to move relative to the mounting base 151 along the first direction X, thereby causing the movable base 242 to move closer to or away from the adhesive clamping assembly 22. The second adhesive clamping drive 243 is mounted on the movable base 242, and the two second adhesive clamping blocks 244 are respectively mounted on the two drive ends of the second adhesive clamping drive 243, thereby enabling the second adhesive clamping drive 243 to drive the two second adhesive clamping blocks 244 to clamp or release the starting end of the adhesive tape. It should be noted that in other embodiments, one of the two second clamping blocks 244 may be installed on the driving end of the second clamping drive 243, so that the second clamping drive 243 drives the second clamping block 244 to approach or move away from the other second clamping block 244, as long as it can clamp or release the passing tape material, and there is no limitation here.

[0074] Optionally, the glue-pulling drive component 241 can be a cylinder, and the second glue-clamping drive component 243 can be a gripper cylinder.

[0075] It should be noted that the movable seat 242 can be mounted on the mounting base 151 by means of guide rods or other guide components, thereby guiding the movement of the movable seat 242 relative to the mounting base 151.

[0076] Specifically, the tape cutting assembly 23 includes a tape cutting drive and a first cutter. The tape cutting drive is mounted on the mounting base 151, and the first cutter is mounted on the drive end of the tape cutting drive, enabling the tape cutting drive to drive the first cutter to move, thereby cutting the tape material in its path. Optionally, the tape cutting drive can be a cylinder.

[0077] In embodiments of this application, the starting assembly 11 further includes a rotary drive 114, and a clamping drive 111 is mounted on the drive end of the rotary drive 114. A first clamping member 112 and a second clamping member 113 are respectively mounted on the two drive ends of the clamping drive 111. The rotary drive 114 can drive the clamping drive 111 to rotate, thereby causing the first clamping member 112 and the second clamping member 113 to rotate as a whole. The clamping drive 111 can drive the first clamping member 112 and the second clamping member 113 to clamp or release the tape. Optionally, the rotary drive 114 can be a rotary cylinder, and the clamping drive 111 can be a gripper cylinder.

[0078] Thus, before adhering to the starting end A41 of the material strip on the spare roll A2, the first clamping member 112 and the second clamping member 113 can be rotated as a whole by the rotary drive 114, so that when the starting assembly 11 moves to the spare material strip A4, a certain adsorption surface B on the second clamping member 113 faces the starting end A41 of the material strip on the spare roll A2, and then the adhesive on the adsorption surface B is used to adhere to the starting end A41 of the material strip on the spare roll A2. Before adhering to the downstream cut end A31 of the working material strip A3, the first clamping member 112 and the second clamping member 113 can be rotated as a whole by the rotary drive 114, so that when the starting assembly 11 moves to the tape receiving mechanism 40, another adsorption surface B on the second clamping member 113 faces the downstream cut end A31 of the working material strip A3, and then the adhesive on the adsorption surface B is used to adhere to the downstream cut end A31 of the working material strip A3.

[0079] It should be noted that the first clamping member 112 and the second clamping member 113 are not limited to being installed on the two driving ends of the same clamping drive member 111. In other embodiments, two clamping drive members 111 may also be provided, both of which are installed on the driving ends of the rotary drive member 114, so that the rotary drive member 114 can drive the two clamping drive members 111 to rotate as a whole. The first clamping member 112 and the second clamping member 113 are respectively installed on the driving ends of the two clamping drive members 111. The two clamping drive members 111 respectively drive the first clamping member 112 and the second clamping member 113 to move closer or further away from each other, so that the first clamping member 112 and the second clamping member 113 together tighten or loosen the tape. Optionally, the two clamping drive members 111 can be cylinders.

[0080] Please see Figures 1 to 3In the embodiments of this application, the driving assembly 13 includes a first driving member 131, a first transfer seat 132, a second driving member 133, a second transfer seat 134, a third driving member 135, and a third transfer seat 136. The first transfer seat 132 is mounted on the driving end of the first driving member 131, enabling the first driving member 131 to drive the first transfer seat 132 to move. The second driving member 133 is mounted on the first transfer seat 132, enabling the second driving member 133 to move along with the first transfer seat 132. The second transfer seat 134 is mounted on the driving end of the second driving member 133, enabling the second driving member 133 to drive the second transfer seat 134 to move relative to the first transfer seat 132. The third driving member 135 is mounted on the second transfer seat 134, enabling the third driving member 135 to move along with the second transfer seat 134. The third transfer seat 136 is mounted on the drive end of the third drive member 135, enabling the third drive member 135 to drive the third transfer seat 136 to move relative to the second transfer seat 134. The aforementioned starting assembly 11 is mounted on the third transfer seat 136, thereby enabling the starting assembly 11 to move together with the third transfer seat 136. Thus, the starting assembly 11 is driven by the first drive member 131, the second drive member 133, and the third drive member 135 to move between the spare material roll A2 on the glue supply mechanism 20, the smoothing assembly 15, the unwinding assembly 31, and the tape splicing mechanism 40, so as to achieve the clamping of tape, smoothing of tape, adhesion of the starting end A41 of the material roll on the spare material roll A2, and adhesion of the downstream cut end A31 of the working material roll A3.

[0081] Optionally, the first driving member 131 drives the first transfer seat 132 to move along the first direction X, the second driving member 133 drives the second transfer seat 134 to move along the second direction Y, and the third driving member 135 drives the third transfer seat 136 to move along the third direction Z. Thus, under the driving action of the first driving member 131, the second driving member 133, and the third driving member 135, the third transfer seat 136 can drive the starting assembly 11 to move along the first direction X, the second direction Y, and the third direction Z. The first direction X, the second direction Y, and the third direction Z intersect each other. Preferably, the first direction X, the second direction Y, and the third direction Z are perpendicular to each other.

[0082] It should be noted that the first driving component 131 can be a linear module, and the second driving component 133 can be a cylinder.

[0083] Optionally, the drive assembly 13 further includes a linear guide 1321 that extends longitudinally along a first direction X. The first transfer seat 132 is slidably connected to the linear guide 1321, thereby guiding the movement of the first transfer seat 132 along the first direction X using the linear guide 1321.

[0084] Optionally, the drive assembly 13 further includes a guide rod 1324 and a limiting plate 1326. A guide hole is formed on the first transfer seat 132, extending through the first transfer seat 132 along the second direction Y. The guide rod 1324 passes through the guide hole and is movable along the axial direction of the guide hole. The limiting plate 1326 is fixedly connected to one end of the guide rod 1324, and the second transfer seat 134 is fixedly connected to the other end of the guide rod 1324, thereby guiding the movement of the second transfer seat 134 relative to the first transfer seat 132 along the second direction Y using the guide rod 1324. The limiting plate 1326 limits the movement of the guide rod 1324 along the guide hole, preventing the guide rod 1324 from dislodging from the guide hole. It should be noted that the number of guide rods 1324 can be two or more, as long as the guiding function is achieved; no limitation is made here.

[0085] Optionally, the second transfer seat 134 is provided with a first slide rail 1344 extending longitudinally in the third direction Z, and the third transfer seat 136 is provided with a first slider 1361. The first slider 1361 is slidably connected to the first slide rail 1344, thereby using the first slide rail 1344 to guide the movement of the third transfer seat 136 relative to the second transfer seat 134 in the third direction Z.

[0086] Optionally, the drive assembly 13 further includes a transmission unit connected between the third drive member 135 and the third transfer seat 136, for converting the rotational motion output by the third drive member 135 into linear motion of the third transfer seat 136 along the third direction Z. Optionally, the third drive member 135 may be a motor.

[0087] Optionally, the transmission unit includes a driving wheel 1341, a driven wheel 1342, and a transmission belt 1343. The driving wheel 1341 is mounted on the output shaft of the third drive member 135, thereby enabling the third drive member 135 to drive the driving wheel 1341 to rotate. The driven wheel 1342 is rotatably connected to the second transfer seat 134 and is spaced apart from the driving wheel 1341 along the third direction Z. The transmission belt 1343 is sleeved between the driving wheel 1341 and the driven wheel 1342, so that when the driving wheel 1341 rotates, it can drive the transmission belt 1343 to move sequentially forward between the driving wheel 1341 and the driven wheel 1342. The third transfer seat 136 is connected to the transmission belt 1343, so that the transmission belt 1343 can drive the third transfer seat 136 to move relative to the second transfer seat 134 along the third direction Z. Thus, in actual use, the third driving component 135 drives the drive wheel 1341 to rotate, thereby driving the transmission belt 1343 to move, so that the transmission belt 1343 drives the third transfer seat 136 to move relative to the second transfer seat 134 along the third direction Z.

[0088] It should be noted that the transmission unit is not limited to a belt drive structure. In other embodiments, a chain drive structure or a gear and rack drive structure can also be used, as long as it can drive the third transfer seat 136 to move relative to the second transfer seat 134 in the third direction Z. This is not limited here.

[0089] In the embodiments of this application, the starting assembly 11 is movably connected to the driving end of the driving assembly 13 along the first direction X. The starting processing mechanism 10 also includes a buffer elastic element 117, which is connected to the third transfer seat 136 and the starting assembly 11, so that the starting assembly 11 can float in the first direction X under the action of an external force. Thus, when the adsorption surface B on the second clamping member 113 of the starting assembly 11 abuts against the spare material roll A2 under the driving action of the driving assembly 13, the starting assembly 11 overcomes the elastic force provided by the buffer elastic element 117 under the action of the pressing force provided by the spare material roll A2, and floats along the first direction X, avoiding a hard impact between the second clamping member 113 and the spare material roll A2 and crushing the spare material roll A2. That is, the buffer elastic element 117 plays a role in buffering the impact between the second clamping member 113 and the spare material roll A2.

[0090] In a specific embodiment, the starting assembly 11 further includes a sliding seat 115, which is movably connected to the third transfer seat 136 along the first direction X. A rotary drive 114 is mounted on the sliding seat 115, allowing the rotary drive 114 to move together with the sliding seat 115. The buffer elastic member 117 can be a buffer cylinder, which is mounted on the third transfer seat 136, with its telescopic end connected to the sliding seat 115. Thus, in actual use, the telescopic end of the buffer cylinder is in the extended state. When the adsorption surface B of the second clamping member 113 abuts against the spare material roll A2, the sliding seat 115 floats along the first direction X, and the buffer cylinder provides a buffering effect.

[0091] It should be noted that the buffer elastic element 117 is not limited to a buffer cylinder. In other embodiments, a buffer spring can also be used, as long as it can play a buffering role. There is no limitation here.

[0092] Furthermore, a second slide rail extending longitudinally along the first direction X is installed on the third transfer seat 136, and a second slider is provided on the sliding seat 115. The second slider is slidably connected to the second slide rail, thereby using the second slide rail to guide the movement of the sliding seat 115 relative to the third transfer seat 136 along the first direction X.

[0093] In the embodiments of this application, the roll changing device further includes multiple guide rollers 50. A guide roller 50 is arranged between the tape receiving mechanism 40 and one of the unwinding components 31, and a guide roller 50 is also arranged between the tape receiving mechanism 40 and another of the unwinding components 31. A guide roller 50 is also arranged on the downstream side of the tape receiving mechanism 40. Each guide roller 50 is used for the passing tape (working tape A3 or spare tape A4) to be wound around.

[0094] When the tape on one adsorption surface B of the second clamping member 113 (i.e., a second section of the tape) is bonded to the starting end A41 of the spare tape A4, and the tape on the other adsorption surface B (i.e., another second section of the tape) is bonded to the downstream cut end A31 of the working tape A3, the adhesive surface of the first section of the tape is exposed. In the subsequent conveying process, this exposed part is prone to sticking to other components, thereby affecting the conveying of the tape. To overcome the above-mentioned defects, in this embodiment, after the downstream cut end A31 of the working material belt and the starting end A41 of the spare material belt are connected (at this time, a section of the working material belt's uncut end is left unattached by the adhesive tape), the unwinding assembly 31 installed on the spare material roll A2 alternately performs unwinding and rewinding actions, so that the connection between the working material belt A3 and the spare material belt A4 passes through the upstream and / or downstream rollers 50 of the connecting mechanism 40, thereby smoothing out the section of the working material belt A3's downstream cut end A31 and attaching it to the first section of the adhesive tape by the rollers 50, thus preventing the first section of the adhesive tape from being exposed, and making the connection between the working material belt A3 and the spare material belt A4 more stable.

[0095] Please see Figure 1 , Figure 7 and Figure 8 As shown, the tape-connecting mechanism 40 includes a first tape-connecting assembly 41, a cutting assembly 45, and a second tape-connecting assembly 43. The first tape-connecting assembly 41 includes a first tape-connecting drive member 411 and a first suction plate 413, the first suction plate 413 being connected to the drive end of the first tape-connecting drive member 41. The second tape-connecting assembly 43 includes a second tape-connecting drive member 431 and a second suction plate 433, the second suction plate 433 being connected to the drive end of the second tape-connecting drive member 431. The first suction plate 413 and the second suction plate 433 are spaced apart along a first direction X, forming a tape-passing channel 47 between them for the working tape A1 to pass through. The cutting assembly 45 is used to cut the working tape A1 passing through the tape-passing channel 47. Optionally, the first tape-connecting drive member 411 and the second tape-connecting drive member 431 can be cylinders.

[0096] Thus, when the workpiece A1 on the unwinding assembly 31 is unwound, firstly, the first tape-connecting drive member 411 and the second tape-connecting drive member 431 respectively drive the first adsorption plate 413 and the second adsorption plate 433 to move closer to each other until the workpiece A1 is clamped between them. Then, the cutting assembly 45 cuts the workpiece A1, so that the downstream cut end of the workpiece A1 is clamped and fixed by the first adsorption plate 413 and the second adsorption plate 433. Then, the first adsorption plate 413 or the second adsorption plate 433 adsorbs and fixes the downstream cut end of the workpiece A1, and the first tape-connecting drive member 411 and the second tape-connecting drive member 431 respectively drive the first adsorption plate 413 and the second adsorption plate 433 away from each other.

[0097] In a specific embodiment, the first tape-connecting assembly 41 further includes a movable seat 415 mounted on the drive end of the first tape-connecting drive member 411. A first suction plate 413 is mounted on the movable seat 415, allowing the first suction plate 413 to move along with the movable seat 415. The cutting assembly 45 includes a cutting drive member 451 and a second cutter 453. The cutting drive member 451 is mounted on the movable seat 415, allowing the cutting drive member 451 to also move along with the movable seat 415. The second cutter 453 is mounted on the drive end of the cutting drive member 451, enabling the cutting drive member 451 to drive the second cutter 453 to cut the passing work tape A1. Optionally, the cutting drive member 451 can be a cylinder.

[0098] Furthermore, the first adsorption plate 413 has a first clearance through hole 4131, which penetrates the first adsorption plate 413 along the first direction X. That is, the first clearance through hole 4131 penetrates the side surface of the first adsorption plate 413 facing the second adsorption plate 433 and also penetrates the side surface of the first adsorption plate 413 away from the second adsorption plate 433. The second cutter 453 is disposed in the first clearance through hole 4131, so that the cutting drive member 451 can drive the second cutter 453 through the first clearance through hole 4131 to the side of the first adsorption plate 413 facing the second adsorption plate 433, thereby cutting the working material strip A1 between the first adsorption plate 413 and the second adsorption plate 433.

[0099] Furthermore, the second adsorption plate 433 has a second clearance through hole 4331, which is opposite to the first clearance through hole 4131, so that when the second cutter 453 cuts the working material strip A1, the second cutter 453 enters the second clearance through hole 4331, avoiding the second cutter 453 from contacting the second adsorption plate 433 and being damaged.

[0100] In a specific embodiment, the first adsorption plate 413 has a plurality of first holes on one side of its surface facing the second adsorption plate 433. These plurality of first holes are connected to an external negative pressure source through a pipeline, so that the external negative pressure source can generate negative pressure at each of the first holes to adsorb the working material belt A1.

[0101] The second adsorption plate 433 has a plurality of second holes 4332 on the side surface facing the first adsorption plate 413. The plurality of second holes 4332 are connected to an external negative pressure source through a pipeline, so that the external negative pressure source can generate negative pressure at each of the second holes 4332 to adsorb the working material belt A1.

[0102] The following is combined with Figures 7 to 14 The roll changing process is explained below:

[0103] The unwinding assembly 31 on the left is loaded with a working roll A1. The unwinding assembly 31 drives the working roll A1 to rotate and unwind it to output a working strip A3. The working strip A3 continues to be conveyed downstream after passing through the tape receiving mechanism 40. The unwinding assembly 31 on the right is loaded with a spare strip A4.

[0104] Adhesive preparation process: First, the drive assembly 13 drives the starting assembly 11 to move along the first direction X to the position between the cutting assembly 23 and the pulling assembly 24, so that the adhesive tape between the pulling assembly 24 and the cutting assembly 23 is aligned with the gap between the first clamping member 112 and the second clamping member 113. Then, the drive assembly 13 drives the starting assembly 11 to move along the second direction Y, so that the adhesive tape enters between the first clamping member 112 and the second clamping member 113. The clamping drive assembly 111 drives the first clamping member 112 and the second clamping member 113 to move closer to each other until the adhesive tape between them is clamped. Then, the pulling assembly 24 releases the adhesive tape, and the cutting assembly 23 cuts the adhesive tape. At this time, the first segment of the adhesive tape C is clamped and fixed between the first clamping member 112 and the second clamping member 113, and the two second segments of the adhesive tape C hang down onto the two adsorption surfaces B of the second clamping member 113, respectively. Then, the drive assembly 13 drives the starting assembly 11 to move towards the smoothing assembly 15 along the third direction Z, so that the first clamping member 112 and the second clamping member 113 pass sequentially through the smoothing channel between the first smoothing member 152 and the second smoothing member 153. When the second clamping member 113 passes through the smoothing channel, the first smoothing member 152 and the second smoothing member 153 respectively press the two second segments of the tape C against the two adsorption surfaces B, so that the two second segments of the tape C are flattened and attached to the two adsorption surfaces B of the second clamping member 113, and are then adsorbed and fixed by the two adsorption surfaces B.

[0105] Changing process: When the strip on the working material roll A1 is almost unwound and a changing process is needed, the tape splicing mechanism 40 clamps the passing working material strip A3 and cuts it. At this time, the unwinding assembly 31 on the left drives the working material roll A1 to rewind until the upstream cut end of the working material strip A3 is wound onto the working material roll A1. The downstream cut end A31 of the working material roll A1 is attracted and fixed by the tape splicing mechanism 40.

[0106] Then, the drive assembly 13 drives the starting assembly 11 to move toward the spare roll A2 on the unwinding assembly 31 on the right, until one of the adsorption surfaces B of the second clamping member 113 abuts against the spare roll A2, so that the tape C on the adsorption surface B adheres to the starting end A41 of the tape on the spare roll A2. Next, the drive assembly 13 drives the starting assembly 11 to move away from the spare roll A2, thereby pulling out the spare tape A4 from the spare roll A2. Then, the drive assembly 13 drives the starting assembly 11 to move to the tape splicing mechanism 40, and uses the tape C on the other adsorption surface B of the second clamping member 113 to pick up the downstream cut end A31 of the working tape A3. At this time, the downstream cut end A31 of the working tape A3 and the starting end A41 of the spare tape A4 are both adhered to the tape C (a certain length of the downstream cut end A31 of the working tape A3 is left unattached to the tape C), thus achieving tape splicing. Next, the clamping drive 111 drives the first clamping member 112 and the second clamping member 113 to move away from each other and release the tape C, while the drive assembly 13 drives the starting assembly 11 to move along the second direction Y, so that the first clamping member 112 and the second clamping member 113 do not interfere with the movement of the tape. Then, the unwinding assembly 31 on the right side alternately performs unwinding and rewinding actions, causing the spare tape A4 to move upstream or downstream, thereby driving the downstream cut end A31 of the working tape A3 to pass through the roller 50, and under the smoothing action of the roller 50, the reserved portion of the downstream cut end A31 of the working tape A3 is smoothed and pasted onto the first section of the tape C. At this time, the spare roll A2 on the unwinding assembly 31 on the left side is switched to the working roll A1, and the working tape A3 continues to be unwound and output downstream. A new roll can be reloaded on the unwinding assembly 31, which serves as the spare roll A2, in preparation for the next roll change.

[0107] It should be noted that the order of the steps in the roll changing process described above is only one implementation method. Other execution orders can also be used, and it is not limited to this one, as long as the switching between working roll A1 and spare roll A2 can be achieved. No limitation is made here.

[0108] Based on the aforementioned rewinding equipment, this application also provides a winding machine. The winding machine includes a winding device and a rewinding device as described in any of the above embodiments. The winding device is arranged downstream of the tape receiving mechanism 40 and is used to wind the passing work tape A3.

[0109] 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.

[0110] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
