Description

Technical Field

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

[0002] In the battery manufacturing process, it is often necessary to continuously unwind and output the material strip on the roll downstream. For example, in the cell winding process, electrode sheets need to be continuously unwound and output to the winding device. When the working material strip on the working roll is unwound, it needs to be cut and then connected to the spare material strip of the spare roll (i.e., splicing), so that the material strip can continue to be unwound and output downstream, thus completing the roll change.

[0003] In the existing technology, in order to achieve a smooth connection between the working material strip and the spare material strip, it is necessary to manually pull the starting end of the material strip on the spare material roll to the designated state, and to cut and apply double-sided tape to the starting end of the material strip. This results in a low degree of automation of the roll changing equipment, requires personnel to be on duty, increases labor costs, and reduces production efficiency. Utility Model Content

[0004] Therefore, it is necessary to provide a starting mechanism, a connecting device, and battery manufacturing equipment that can be highly automated and improve production efficiency to address the above problems.

The oscillating drive is mounted on the drive end of the drive assembly, the mounting frame is mounted on the drive end of the oscillating drive, and the oscillating roller is mounted on the mounting frame.

[0009] In some embodiments, the oscillating drive is used to drive the oscillating roller to oscillate around the gripping assembly.

[0010] In some embodiments, the drive assembly is used to drive the pressing assembly and the clamping assembly to move closer to or away from the roll, the clamping assembly is used to clamp the starting end of the strip on the roll, and the oscillating roller can press the strip between the clamping assembly and the roll against the adhesive roller when it oscillates.

[0015] In some embodiments, the drive assembly includes a translation drive and a motion seat mounted on the drive end of the translation drive, the oscillating drive is mounted on the motion seat, and the mounting bracket is rotatably connected to the motion seat and connected to the drive end of the oscillating drive.

[0016] A tape-attaching device includes a starting mechanism as described in any of the above embodiments.

[0017] A battery manufacturing apparatus includes the splicing device as described in any of the above embodiments.

[0018] The aforementioned starting mechanism, tape-attaching device, and battery manufacturing equipment utilize the oscillating motion of the oscillating roller to press the spare material tape against the corresponding adhesive roller, thereby enabling the adhesive roller to use the adhesive tape on it to pick up the spare material tape. This achieves automatic picking up of the spare material tape from the spare material roll, further improving the automation level of the equipment.

[0040] This application provides a battery manufacturing apparatus, which can be a winding device, or other equipment that requires unwinding the output strip; no limitation is made here. For ease of understanding, this document uses a winding device as an example for illustration.

[0041] Please see Figures 1 to 5 The battery manufacturing equipment includes a tape splicing device and a winding device. The tape splicing device is used to load the working material roll A1 and the spare material roll A2, and to drive the working material roll A1 to unwind and output the working material tape a1 to the winding device. The winding device is used to wind the working material tape a1 to form a core. The tape splicing device is also used to cut the spare material tape a2, and to cut the working material tape a1 when the working material roll A1 is almost used up, and to use tape B to bond the downstream cut end a11 of the working material tape a1 and the upstream cut end a21 of the spare material tape a2, thus realizing tape splicing.

[0042] The tape feeding device includes an unwinding mechanism 10, a cutting mechanism 20, an adhesive applicator 30, and a starting mechanism 40. The unwinding mechanism 10, cutting mechanism 20, and adhesive applicator 30 are arranged sequentially from upstream to downstream. The unwinding mechanism 10 includes two unwinding assemblies 11, each capable of loading a roll of material (i.e., a working roll A1 or a spare roll A2). When one unwinding assembly 11 is loaded with a working roll A1, the other unwinding assembly 11 is loaded with a spare roll A2. The unwinding assembly 11 drives the working roll A1 on it to unwind downstream, outputting a working tape a1. This working tape a1 passes sequentially through the cutting mechanism 20 and the adhesive applicator 30, and is then conveyed downstream to the winding device. The starting mechanism 40 is used to pick up the starting end a23 of the tape on the spare roll A2 (see...). Figure 16The adhesive applicator 30 uses adhesive tape B to pick up the spare material tape a2, and the starting mechanism 40 is also used to cut the starting end a23 of the spare material tape a2, so that the upstream cut end a21 of the spare material tape a2 is pasted on the adhesive tape B of the adhesive applicator 30. The adhesive applicator 30 uses adhesive tape B to pick up the passing working material tape a1, and the cutting mechanism 20 is used to cut the passing working material tape a1, so that the downstream cut end a11 of the working material tape a1 is pasted on the adhesive tape B of the adhesive applicator 30, thereby realizing the bonding of the upstream cut end a21 of the spare material tape a2 and the downstream cut end a11 of the working material tape a1 using adhesive tape B, that is, realizing the tape splicing.

[0043] Please see also Figures 6 to 9 In the embodiments of this application, the adhesive applicator 30 includes two adhesive applicator components 30a. Each adhesive applicator component 30a includes a first drive member 32, a first transfer seat 33, a rotation drive member 34, and an adhesive applicator roller 31. The first transfer seat 33 is mounted on the drive end of the first drive member 32, enabling the first drive member 32 to drive the first transfer seat 33 to move. The rotation drive member 34 is mounted on the first transfer seat 33, and the adhesive applicator roller 31 is disposed on the first transfer seat 33 and connected to the drive end of the rotation drive member 34, enabling the first drive member 32 to drive the first transfer seat 33 to move, thereby causing the first transfer seat 33 to drive the adhesive applicator roller 31 thereon to move together. The adhesive applicator rollers 31 of the two adhesive applicator components 30a are arranged opposite to each other, and an adhesive applicator channel for the work material strip a1 to pass through is formed between them. Under the driving action of the first drive member 32 of the two adhesive applicator components 30a, the two adhesive applicator rollers 31 can move closer or further away from each other, thereby clamping or releasing the work material strip a1 between them. Each adhesive roller 31 has multiple holes a3 on its peripheral surface. Each hole a3 on the adhesive roller 31 is connected to an external negative pressure source through a pipe, so that the external negative pressure source can generate negative pressure at each hole a3, thereby adsorbing the adhesive tape B onto the peripheral surface of the adhesive roller 31.

[0044] In actual use, please refer to Figures 1 to 5 One unwinding assembly 11 is loaded with a working material roll A1, which rotates to unwind and output the working material strip a1 downstream. The working material strip a1 passes sequentially between the cutting mechanism 20 and the two adhesive rollers 31, and then reaches the winding device, which winds the working material strip a1. The other unwinding assembly 11 is loaded with a spare material roll A2, which is used to replace the working material roll A1 after the working material roll A1 is unwound and continue to unwind and output the working material strip a1 downstream. Adhesive tape B is adsorbed and fixed on the peripheral surface of both adhesive rollers 31.

[0045] First, the starting mechanism 40 picks up the starting end a23 of the material strip on the spare material roll A2 and pulls out a certain length of spare material strip a2, so that the spare material strip a2 between the starting mechanism 40 and the spare material roll A2 is attached to the tape B of the corresponding adhesive roller 31. Then, the starting mechanism 40 cuts the starting end a23 of the spare material strip a2, and at this time, the upstream cut end a21 of the spare material strip a2 is attached to the tape B of the adhesive roller 31. When the working material roll A1 is almost unwound, the two first drive members 32 drive the two adhesive rollers 31 to move closer to each other until the working material strip a1 between them is clamped. Then, the cutting mechanism 20 cuts the working material strip a1 from the upstream side of the two adhesive rollers 31, and the two rotation drive members 34 drive the two adhesive rollers 31 to rotate in opposite directions, thereby causing the downstream cut end a11 of the working material strip a1 and the upstream cut end a21 of the spare material strip a2 to pass between the two adhesive rollers 31 in sequence. When the downstream cut end a11 of the working material belt a1 and the upstream cut end a21 of the spare material belt a2 pass between the two adhesive rollers 31, the adhesive tape B on the two adhesive rollers 31 adheres between the downstream cut end a11 of the working material belt a1 and the upstream cut end a21 of the spare material belt a2, and moves downstream together with the working material belt a1 and the spare material belt a2, separating from the adhesive rollers 31, thus achieving tape splicing. After the adhesive tape B is completely separated from the adhesive rollers 31, the two first drive units 32 drive the two adhesive rollers 31 away from each other, releasing the spare material belt a2. At this time, the spare material roll A2 is switched to the working material roll A1, and the working material belt a1 continues to be unwound and output downstream.

[0046] Thus, the adhesive applicator 30 of this application automatically completes the process of adhering to the downstream cut end a11 of the working material strip a1 and the upstream cut end a21 of the spare material strip a2 by moving and rotating the two adhesive rollers 31. The downstream cut end a11 of the working material strip a1 and the upstream cut end a21 of the spare material strip a2 are then bonded together by the adhesive tape B, thereby achieving automatic tape splicing. No manual processing of the adhesive tape B and the material strip is required, which helps to improve the automation level of the equipment, improve the tape splicing efficiency, eliminate the need for personnel on duty, and reduce labor costs.

[0047] It should also be noted that during the conveyor belt connection process, the working belt can be continuously conveyed downstream or the conveyor belt can be paused only when the working belt is cut. The equipment does not need to stop operating or only needs to stop operating for a short time, which greatly improves production efficiency.

[0048] It is important to emphasize that after the working conveyor belt a1 is cut, two cut ends are formed at the break point. The one located upstream is the upstream cut end, and the one located downstream is the downstream cut end. Similarly, after the spare conveyor belt a2 is cut, two cut ends are formed at the break point. The one located upstream is the upstream cut end, and the one located downstream is the downstream cut end. In this article, upstream and downstream refer to the conveyor belt's path. The position where the conveyor belt arrives first is upstream, and the position where the conveyor belt arrives later is downstream.

[0049] It should also be noted that the first driving member 32 can be a linear drive module, such as an electric cylinder or a pneumatic cylinder, as long as it can drive the first transfer seat 33 to move the adhesive roller 31 on it closer to or away from the other adhesive roller 31. This is not a limitation. Of course, in other embodiments, the first driving member 32 can also drive the first transfer seat 33 to perform a swinging motion, as long as it can cause the first transfer seat 33 to move the adhesive roller 31 on it closer to or away from the other adhesive roller 31. This is not a limitation. For ease of understanding, this article uses the example of the first driving member 32 driving the first transfer seat 33 to move the adhesive roller 31 on it along a straight line closer to or away from the other adhesive roller 31 as an example.

[0050] The rotation drive component 34 can be a rotating drive component such as a motor, as long as it can drive the adhesive roller 31 to rotate, and there is no limitation here.

[0051] Please continue reading Figures 6 to 9 In the embodiments of this application, the adhesive roller 31 includes an inner shaft 311 and a bushing 313. The inner shaft 311 is fixedly connected to the first transfer seat 33, and the bushing 313 is sleeved on the outside of the inner shaft 311 and is rotatable relative to the inner shaft 311. The bushing 313 is connected to the driving end of the rotation drive member 34, so that the rotation drive member 34 can drive the bushing 313 to rotate relative to the inner shaft 311. The bushing 313 has a plurality of holes a3 as described above, and one side surface area of ​​the inner shaft 311 is recessed to form a cavity a4, that is, one side surface of the inner shaft 311 has a cavity a4, and the other side surface of the inner shaft 311 does not have a cavity a4. The cavity a4 is used to communicate with an external negative pressure source, so that the external negative pressure source can form negative pressure in the cavity a4. During the rotation of the drive component 34, the bushing 313 rotates relative to the inner shaft 311. Each hole a4 on the bushing 313 passes through the side of the inner shaft 311 with cavity a4 and communicates with the cavity a4. Thus, the holes a3 that pass through the side of the inner shaft 311 with cavity a4 can generate an adsorption force on the tape B, while the holes a3 that do not pass through the side of the inner shaft 311 with cavity a4 will not generate an adsorption force.

[0052] Thus, tape B is adsorbed and fixed onto the circumferential surface of bushing 313 by a portion of the hole a3 on one side of the inner shaft 311 with cavity a4. When adhesive application is required, the two rotating drive members 34 drive the bushings 313 of the two adhesive application rollers 31 to rotate in opposite directions, so that tape B on the two bushings 313 gradually enters between the two adhesive application rollers 31, and gradually adheres tape B to the area between the downstream cut end a11 of the working material belt a1 and the upstream cut end a21 of the spare material belt a2. Since the hole a3 on the bushing 313 leaves the side of the inner shaft 311 with cavity a4 after passing between the two adhesive rollers 31 (i.e., it is not connected to cavity a4), the adsorption of tape B stops. This allows the part of tape B that has not yet passed between the two adhesive rollers 31 to continue to be adsorbed and fixed on the bushing 313. The part of tape B that has passed between the two adhesive rollers 31 separates from the bushing 313 and is pasted on the working material belt a1 and the spare material belt a2. This achieves the transfer of tape B from the bushing 313 of the adhesive roller 31 to the working material belt a1 and the spare material belt a2.

[0053] It should be noted that, relative to the strip passing between the two adhesive rollers 31, the downstream side of the inner shaft 311 of the two adhesive rollers 31 (i.e. Figure 8 The upper side of the inner shaft 311 of the two adhesive rollers 31 does not have the aforementioned cavity a4, and the upstream side of the inner shaft 311 of the two adhesive rollers 31 (i.e. Figure 8 The inner shafts 311 of the two adhesive rollers 31 have cavities a4, which allows the adhesive tape B on the two bushings 313 to be adsorbed and fixed on the bushings 313 by the corresponding holes a3 before entering between the two adhesive rollers 31. After the adhesive tape B on the two bushings 313 passes between the two adhesive rollers 31, the part that has passed through will not be adsorbed on the bushings 313, but will be stuck between the downstream cut end a11 of the working material belt a1 and the upstream cut end a21 of the spare material belt a2, and will move downstream together with the working material belt a1 and the spare material belt a2. This ensures that the adhesive tape B on the bushings 313 of the two adhesive rollers 31 is gradually transferred to the area between the downstream cut end a11 of the working material belt a1 and the upstream cut end a21 of the spare material belt a2, ensuring that the adhesive application process is stable and reliable, greatly improving the quality of adhesive application, and helping to improve the yield.

[0054] Furthermore, the plane containing the central axes of the two adhesive rollers 31 is a dummy plane, meaning the central axes of the two adhesive rollers 31 lie within this dummy plane. The cavities a4 on the two inner shafts 311 are located on the same side of this dummy plane, i.e., both are located upstream of the inner shafts 311, ensuring that the tape B can be adsorbed and fixed onto the bushing 313 upstream of the inner shafts 311, while no adsorption force can be generated on the tape B downstream of the inner shafts 311. Specifically... Figure 8 In the embodiment shown, the cavities a4 on the inner shafts 311 of the two adhesive rollers 31 are both located on the lower side of the inner shafts 311.

[0055] Furthermore, the inner shaft 311 has an airflow channel inside, one end of which is connected to the cavity a4, and the other end of which is connected to an external negative pressure source through a pipe. Thus, when it is necessary to adsorb the tape B, the external negative pressure source evacuates the cavity a4 through the airflow channel, thereby generating negative pressure in the cavity a4. The negative pressure in the cavity a4 is transmitted to the connected holes a3, thereby adsorbing and fixing the tape B onto the bushing 313.

[0056] In embodiments of this application, the adhesive application assembly 30a further includes a tape unwinding member 35, a first pressing drive member 361, a first pressure roller 36, a first cutting drive member 371, and a first cutter 37. The tape unwinding member 35, the first pressing drive member 361, and the first cutting drive member 371 are all disposed on a first transfer seat 33 to move together with the first transfer seat 33. The first pressure roller 36 is mounted on the driving end of the first pressing drive member 361 and is located downstream of the tape unwinding member 35, and is arranged opposite to the adhesive application roller 31. Further, the adhesive application assembly 30a also includes a second pressing drive member 381 and a second pressure roller 38. The second pressing drive member 381 is disposed on the first transfer seat 33, and the second pressure roller 38 is mounted on the driving end of the second pressing drive member 381 and is located downstream of the first cutter 37, and is arranged opposite to the adhesive application roller 31. Optionally, both the first pressing drive 361 and the second pressing drive 381 can be cylinders, and the first cutting drive 371 can also be a cylinder.

[0057] The tape unwinding unit 35 is used to unwind and output tape to the first pressure roller 36. This tape passes between the first pressure roller 36, the second pressure roller 38, and the corresponding applicator roller 31. The first pressing drive unit 361 and the second pressing drive unit 381 can respectively drive the first pressure roller 36 and the second pressure roller 38 towards the corresponding applicator roller 31 until the first pressure roller 36 and the second pressure roller 38 press the tape tightly onto the applicator roller 31, causing the applicator roller 31 to adhere and fix the tape. The first cutting drive unit 371 is used to drive the first cutter 37 to cut the tape between the first pressure roller 36 and the second pressure roller 38. The cut portion of the tape is the aforementioned tape B. Thus, by utilizing the tape unwinding unit 35, the first pressure roller 36, the second pressure roller 38, and the first cutter 37, tape B is automatically supplied to the applicator roller 31, preparing for the next splicing, further improving the automation level of the equipment, increasing splicing efficiency, and reducing labor costs. Since the first pressing drive 361 and the first pressure roller 36 can move together with the first transfer seat 33, the first pressure roller 36 can always keep pressing the tape against the adhesive roller 31. This allows the tape to be wound around the adhesive roller 31 while the adhesive roller 31 is applying adhesive between the downstream cut end of the working tape a1 and the upstream cut end of the spare tape a2, thus providing tape B to the adhesive roller 31. Therefore, the time spent waiting to prepare adhesive for the adhesive roller 31 is saved during the production process, which helps to improve production efficiency.

[0058] It should be noted that in other embodiments, the tape unwinding member 35 and the second pressing drive member 381 may not be installed on the first transfer seat 33. That is, the tape unwinding member 35, the second pressing drive member 381 and the second pressure roller 38 may not move together with the first transfer seat 33. As long as the tape B can be provided to the adhesive roller 31, it is not limited here.

[0059] It should also be noted that the second pressing drive 381 is not essential. In other embodiments, the second pressing drive 381 may be omitted, and instead, the second pressure roller 38 may be mounted on the drive end of the first cutting drive 371. That is, the second pressure roller 38 and the first cutter 37 share a single drive unit. Specifically, while the first cutting drive 371 drives the second pressure roller 38 to press the adhesive tape onto the adhesive roller 31, it also drives the first cutter 37 to cut the adhesive tape between the first pressure roller 36 and the second pressure roller 38.

[0060] In a specific embodiment, each adhesive roller 31 has a cutting groove a7 on its peripheral surface for the first cutter 37 to enter and exit. Specifically, the cutting groove a7 is formed on the bushing 313 of the adhesive roller 31 and extends longitudinally along the axial direction of the bushing 313. In this way, the cutting groove a7 avoids the first cutter 37, preventing the first cutter 37 from directly contacting and damaging the adhesive roller 31 when cutting the adhesive tape.

[0061] Optionally, the bushing 313 has cutting grooves a7 on both sides of its radial direction, so that either cutting groove a7 can be used to avoid cutting the tape when the first cutter 37 cuts the tape.

[0062] It should be noted that the portion of the bushing 313 located on the side of the inner shaft 311 with cavity a4 is the adsorption area a5, and the portion of the bushing 313 located on the side of the inner shaft 311 without cavity a4 is the non-adsorption area a6. The first pressure roller 36 presses against the non-adsorption area a6 of the bushing 313, and the second pressure roller 38 presses against the adsorption area a5 of the bushing 313, thereby ensuring that the tape B formed by the first cutter 37 cutting the tape material between the first pressure roller 36 and the second pressure roller 38 is adsorbed and fixed on the adsorption area a5 of the bushing 313.

[0063] Please see Figures 10 to 12 In the embodiments of this application, the starting mechanism 40 includes a driving assembly 41, a clamping assembly 43, and a pressing assembly 45. Both the clamping assembly 43 and the pressing assembly 45 are mounted on the driving end of the driving assembly 41, enabling the driving assembly 41 to drive the clamping assembly 43 and the pressing assembly 45 to move together. The clamping assembly 43 has a clamping member 431 for clamping the starting end a23 of the material strip on the spare material roll A2. The pressing assembly 45 is used to feed the spare material strip a2 between the clamping assembly 43 and the spare material roll A2 to the corresponding adhesive roller 31, so that the adhesive strip B on the adhesive roller 31 adheres to the spare material strip a2. Further, the pressing assembly 45 has a swinging drive member 451 and a swinging roller 452. The swinging roller 452 is oscillatingly arranged around the clamping member 431 and connected to the driving end of the swinging drive member 451, thereby enabling the swinging drive member 451 to drive the swinging roller 452 to swing around the clamping member 431.

[0064] Therefore, when a connection is required, please refer to [the relevant documentation / reference]. Figures 16 to 18 As shown, firstly, the drive assembly 41 drives the clamping member 431 of the clamping assembly 43 to move closer to the spare material roll A2, so that the clamping member 431 clamps the starting end a23 of the material strip on the spare material roll A2; then, the drive assembly 41 drives the clamping member 431 of the clamping assembly 43 to move away from the spare material roll A2, thereby pulling out a certain length of spare material strip a2; then, the swing drive assembly 451 drives the swing roller 452 to swing around the clamping member 431, so that the swing roller 452 presses the spare material strip a2 between the spare material roll A2 and the clamping member 431 against the corresponding adhesive roller 31; then, the drive assembly 41 drives the clamping assembly 43 and the pressing assembly 45 to move toward the corresponding adhesive roller 31 until the swing roller 452 abuts against the corresponding adhesive roller 31, so that the spare material strip a2 wrapped on the swing roller 452 is pasted onto the adhesive strip B on the corresponding adhesive roller 31, thereby realizing that the adhesive roller 31 uses the adhesive strip B on it to stick the spare material strip a2.

[0065] It should be noted that the clamping member 431 clamps the starting end a23 of the material strip on the spare material roll A2 and pulls out a certain length of spare material strip a2. Then, the swinging roller 452 swings to press the spare material strip a2 against the corresponding adhesive roller 31, so that the adhesive roller 31 uses the adhesive strip B on it to stick the spare material strip a2. That is, the spare material strip a2 on the spare material roll A2 is automatically stuck, which further improves the automation level of the equipment. Moreover, the sticking of the spare material strip a2 on the spare material roll A2 is stable and reliable, which further improves the production efficiency.

[0066] In a specific embodiment, the pressing assembly 45 further includes a mounting frame 47. A swing drive 451 is mounted on the drive end of the drive assembly 41, and the mounting frame 47 is mounted on the drive end of the swing drive 451. The aforementioned clamping member 431 and swing roller 452 are both disposed on the mounting frame 47, so that when the drive assembly 41 drives the mounting frame 47 to move, the mounting frame 47 can drive the clamping member 431 and swing roller 452 to move together; when the swing drive 451 drives the mounting frame 47 to rotate, it can drive the clamping member 431 and swing roller 452 to rotate together. Further, the central axis of the clamping member 431 is approximately collinear with the rotation axis of the mounting frame 47, and the axis of the swing roller 452 is parallel to but not collinear with the rotation axis of the mounting frame 47. This allows the mounting frame 47 to rotate when it rotates, driving the clamping member 431 to rotate around its own central axis, while simultaneously driving the swing roller 452 to swing around the clamping member 431 (i.e., the rotation axis of the mounting frame 47).

[0067] In a specific embodiment, two oscillating rollers 452 are configured, both mounted on the mounting frame 47 and spaced apart along the rotation direction of the mounting frame 47. Each of the two oscillating rollers 452 corresponds to one of the two adhesive rollers 31, ensuring that the spare roll A2 can be spliced ​​on either unwinding assembly 11. Figure 17 and Figure 18 In the embodiment shown, the spare material roll A2 is on the left unwinding assembly 11. When the tape is picked up, the mounting frame 47 drives the two swing rollers 452 to swing clockwise, so that the corresponding swing roller 452 abuts against the left adhesive roller 31, that is, the spare material tape a2 is pressed against the tape B on the left adhesive roller 31.

[0068] If the spare roll A2 is on the right unwinding assembly 11, when the tape is spliced, the mounting bracket 47 drives the two swing rollers 452 to swing counterclockwise, so that the other swing roller 452 abuts against the right adhesive roller 31, that is, the spare tape a2 is pressed against the tape B on the right adhesive roller 31.

[0069] In a specific embodiment, the pressing assembly 45 further includes a second cutting drive 456 and a second cutter 455. The second cutting drive 456 is mounted on the mounting bracket 47, and the second cutter 455 is mounted on the driving end of the second cutting drive 456 and located between the two oscillating rollers 452. Thus, after the oscillating rollers 452 press the spare material strip a2 against the adhesive strip B on the adhesive roller 31, the second cutting drive 456 drives the second cutter 455 to move, causing the second cutter 455 to cut the spare material strip a2 at a position between the two oscillating rollers 452. At this time, the upstream cut end a21 of the spare material strip a2 is adhered to the adhesive strip B on the adhesive roller 31. Optionally, the second cutting drive 456 can be a cylinder.

[0070] In a specific embodiment, the pressing assembly 45 further includes a second elastic element 453 and a second transfer seat 454. The second transfer seat 454 is movably connected to the mounting frame 47. The second elastic element 453 connects the second transfer seat 454 and the mounting frame 47, allowing the second transfer seat 454 to float to a certain extent in the direction of approaching or moving away from the clamping member 431. A swing roller 452 is mounted on the second transfer seat 454, allowing the swing roller 452 to float together with the second transfer seat 454 in the direction of approaching or moving away from the clamping member 431. Optionally, the second elastic element 453 can be a spring or a cylinder.

[0071] Thus, under the driving action of the drive assembly 41, after the clamping member 431 pulls out a certain length of spare material strip a2, under the driving action of the swing drive member 451, the swing roller 452 swings around the clamping member 431, so that the swing roller 452 presses the spare material strip a2 between the clamping member 431 and the spare material roll A2 against the corresponding adhesive roller 31; then, under the driving action of the drive assembly 41, the mounting bracket 47 moves toward the corresponding adhesive roller 31 until the swing roller 452 abuts against the corresponding adhesive roller 31 (at this time, the compression of the second elastic member 453 increases). Then, the second cutting drive member 456 drives the second cutter 455 to cut the spare material strip a2, at which time the upstream cutting end a21 of the spare material strip a2 is in a suspended state. Then, the drive assembly 41 continues to drive the mounting bracket 47 to move, thereby causing the oscillating roller 452 to roll along the adhesive roller 31 it abuts, so as to roll the upstream cut end a21 of the spare material strip a2 onto the adhesive strip B on the adhesive roller 31. Then, under the driving action of the oscillating drive 451, the oscillating roller 452 swings away from the adhesive roller 31 around the clamping member 431, preparing for the next pressing action.

[0072] In embodiments of this application, the clamping assembly 43 further includes an air blowing element 432. Both the clamping element 431 and the air blowing element 432 are mounted on the mounting bracket 47, and the air blowing element 432 is located on one side of the clamping element 431. Further, the air outlet c1 of the air blowing element 432 (see...) Figure 13The air blower 432 is positioned approximately towards the clamping member 431, allowing it to blow the starting end a23 of the strip on the spare roll A2 into the clamping member 431, so that the clamping member 431 can hold and fix the starting end a23 of the strip. Thus, when it is necessary to clamp the starting end a23 of the strip on the spare roll A2, firstly, the drive assembly 41 drives the mounting bracket 47 to move closer to the spare roll A2, causing the mounting bracket 47 to move the air blower 432 and the clamping member 431 closer to the spare roll A2; then, the air blower 432 blows air towards the clamping member 431, causing the starting end a23 of the strip on the spare roll A2 to be blown into the clamping member 431 and clamped and fixed by the clamping member 431 (see...). Figure 16 Then, the drive assembly 41 drives the mounting bracket 47 to move away from the spare material roll A2, thereby driving the clamping member 431 to pull out a certain length of spare material strip a2, thus realizing the starting process of the spare material roll A2.

[0073] Furthermore, two air-blowing components 432 are provided, and the two air-blowing components 432 are respectively arranged on opposite sides of the clamping component 431. Specifically... Figure 16 , Figure 17 and Figure 18 In the embodiment shown, the spare material strip a2 on the spare material roll A2 is wound clockwise. When the starting end a23 of the material strip on the spare material roll A2 is clamped, the starting end a23 of the material strip is blown into the clamping member 431 by the air blowing member 432 above and clamped and fixed by the clamping member 431.

[0074] Specifically Figure 19 and Figure 20 In the embodiment shown, the spare material strip a2 on the spare material roll A2 is wound counterclockwise. When the starting end a23 of the material strip on the spare material roll A2 is clamped, the starting end a23 of the material strip is blown into the clamping member 431 by the air blowing member 432 below and clamped and fixed by the clamping member 431.

[0075] In a specific embodiment, the clamping assembly 43 further includes two first guide rollers 433, both mounted on the mounting frame 47. The clamping member 431 is located between two air blowing members 432, and the two air blowing members 432 are located between the two first guide rollers 433. Thus, after the clamping member 431 clamps the starting end a23 of the material strip, the spare material strip a2 will pass around the first guide rollers 433 during the rotation of the mounting frame 47, preventing the spare material strip a2 from contacting and being damaged by components such as the air blowing members 432.

[0076] Please see Figures 13 to 15Specifically, in this embodiment, the clamping assembly 43 further includes a pressure roller 434 mounted on the air blowing member 432. This pressure roller 434 abuts against the spare material roll A2, thereby positioning the clamping assembly 43. Thus, when it is necessary to clamp the starting end a23 of the material strip from the spare material roll A2, firstly, the drive assembly 41 drives the mounting frame 47 to move towards the spare material roll A2. This causes the mounting frame 47 to move the clamping member 431 and the air blowing member 432 closer to the spare material roll A2 until the pressure roller 434 on the air blowing member 432 abuts against the spare material roll A2, ensuring that the air blowing member 432 and the clamping member 431 are in position. Then, the air blowing member 432 blows the starting end a23 of the material strip from the spare material roll A2 into the clamping member 431, which clamps and fixes the starting end a23. Then, the drive assembly 41 drives the mounting bracket 47 to move away from the spare roll A2, causing the pressure roller 434 to separate from the spare roll A2, and causing the clamping member 431 to pull out a certain length of spare strip a2.

[0077] It should be noted that the number of pressure rollers 434 on the air blowing component 432 is not limited to one. In other embodiments, two or more pressure rollers 434 can be installed on the air blowing component 432. By using these two or more pressure rollers 434 to abut against the spare material roll A2, the positioning of the air blowing component 432 and the clamping component 431 is more accurate and reliable. When there are multiple pressure rollers 434 on the air blowing component 432, these multiple pressure rollers 434 are arranged at intervals along the axial direction of the spare material roll A2.

[0078] Specifically, in this embodiment, the air-blowing component 432 has a first end b1 and a second end b2 as its two opposite ends. The air-blowing component 432 is rotatably connected to the mounting bracket 47, and the first end b1 and the second end b2 of the air-blowing component 432 are respectively located on both sides of the rotation axis of the air-blowing component 432. The pressure roller 434 is mounted on the second end b2 of the air-blowing component 432, and the air outlet c1 of the air-blowing component 432 is also located on the second end b2. The clamping assembly 43 also includes a first elastic member 436, the two ends of which abut against the mounting bracket 47 and the first end b1 of the air-blowing component 432, respectively. Thus, during the process of the drive assembly 41 driving the pressure roller 434 to abut against the spare material roll A2, the first elastic member 436 plays a buffering role, avoiding hard impact between the pressure roller 434 and the spare material roll A2 and causing damage to the spare material roll A2. It should be noted that the first elastic member 436 can be a compression spring.

[0079] Furthermore, two abutment blocks 435 are fixedly connected to the mounting bracket 47, and the first end b1 of the air blowing element 432 is located between the two abutment blocks 435. There are two first elastic elements 436, one of which abuts between one abutment block 435 and the first end b1 of the air blowing element 432, and the other abuts between another abutment block 435 and one end of the air blowing element 432, so that after the pressure roller 434 is separated from the spare material roll A2, the air blowing element 432 can quickly rotate and reset under the combined action of the two first elastic elements 436.

[0080] Please see again Figure 11 Specifically, in this embodiment, the clamping member 431 includes a clamping drive member 4312 and two grippers 4311. The clamping drive member 4312 is mounted on the mounting bracket 47 and is drivenly connected to one of the grippers 4311. Thus, after the air blowing member 432 blows the starting end a23 of the material strip on the spare material roll A2 between the two grippers 4311, the clamping drive member 4312 drives one of the connected grippers 4311 to move closer to the other gripper 4311 until the two grippers 4311 together clamp the starting end a23 of the material strip.

[0081] Furthermore, the clamping member 431 also includes a fixed base 4313 and a movable base 4314, both of which are mounted on the mounting bracket 47. The movable base 4314 is movably connected to the mounting bracket 47 and connected to the drive end of the clamping drive member 4312, enabling the clamping drive member 4312 to drive the movable base 4314 to move relative to the mounting bracket 47 closer to or away from the fixed base 4313. One gripper 4311 is mounted on the fixed base 4313, and the other gripper 4311 is mounted on the movable base 4314. Thus, after the air blowing component 432 blows the starting end a23 of the strip on the spare material roll A2 between the two grippers 4311, the clamping drive component 4312 drives the movable seat 4314 to move closer to the fixed seat 4313. This causes the movable seat 4314 to move its grippers 4311 closer to the grippers 4311 on the fixed seat 4313, until both grippers 4311 clamp the starting end a23 of the strip together. Optionally, the clamping drive component 4312 can be a cylinder.

[0082] It should be noted that the two grippers 4311 of the clamping member 431 are not limited to one being movable and the other fixed. In other embodiments, both grippers 4311 can also be movable to move closer to or further away from each other. Specifically, the clamping member 431 also includes two movable seats 4314, and two clamping drive members 4312 are also provided, both of which are mounted on the mounting bracket 47. Both movable seats 4314 are movably connected to the mounting bracket 47 and are arranged opposite to each other, so that the two movable seats 4314 can move closer to or further away from each other. The two movable seats 4314 are respectively connected to the drive ends of the two clamping drive members 4312, so that the clamping drive members 4312 can drive the two movable seats 4314 to move closer to or further away from each other relative to the mounting bracket 47. The two grippers 4311 are respectively mounted on the two movable seats 4314. Thus, after the air blowing component 432 blows the starting end a23 of the material strip on the spare material roll A2 into the space between the two grippers 4311, the two clamping drive components 4312 respectively drive the two movable seats 4314 to move closer to each other, thereby the two movable seats 4314 respectively drive the grippers 4311 on them to move closer to each other until the two grippers 4311 together clamp the starting end a23 of the material strip.

[0083] Please see again Figure 10 Specifically, in this embodiment, the drive assembly 41 includes a translation drive 411 and a motion seat 413 mounted on the drive end of the translation drive 411. A swing drive 451 is mounted on the motion seat 413. A mounting frame 47 is rotatably connected to the motion seat 413 and connected to the drive end of the swing drive 451, enabling the swing drive 451 to drive the mounting frame 47 to rotate, thereby causing the swing roller 452 on the mounting frame 47 to swing. The translation drive 411 drives the motion seat 413 to move, thereby causing the clamping assembly 43 and the pressing assembly 45 on the mounting frame 47 to move between the two unwinding assemblies 11.

[0084] It should be noted that the translation drive 411 can be a linear drive module, such as a cylinder or a pole, as long as it can drive the clamping component 43 and the pressing component 45 on the mounting frame 47 to move between the two unwinding components 11. No limitation is made here.

[0085] Please see Figure 1 and Figure 21In the embodiments of this application, the cutting mechanism 20 includes two cutting components 21 arranged opposite to each other, forming a cutting channel between the two cutting components 21 for the work material strip a1 to pass through. Both cutting components 21 are capable of cutting the work material strip a1 passing through the cutting channel. Thus, after the two adhesive rollers 31 clamp the work material strip a1 between them, the corresponding cutting component 21 cuts the passing work material strip a1, so that when the two adhesive rollers 31 rotate in opposite directions, the adhesive tape B on the two adhesive rollers 31 can be adhered to the downstream cut end a11 of the work material strip a1.

[0086] Specifically Figure 1 In the illustrated embodiment, two cutting components 21 are arranged side to side, namely, a left cutting component 21 and a right cutting component 21. The left cutting component 21 is used for the work material strip a1 unwound from the work material roll A1 on the left unwinding component 11 to be wound around, and is used to cut the work material strip a1 in the path when splicing. The right cutting component 21 is used for the work material strip a1 unwound from the work material roll A1 on the right unwinding component 11 to be wound around, and is used to cut the work material strip a1 in the path when splicing.

[0087] Furthermore, the cutting assembly 21 includes a third moving drive 211, a third transfer seat 212, a second guide roller 214, a third cutting drive 213, and a third cutter 215. The third transfer seat 212 is mounted on the drive end of the third moving drive 211, enabling the third moving drive 211 to drive the third transfer seat 212 to move. The second guide roller 214 and the third cutting drive 213 are both mounted on the third transfer seat 212, enabling the second guide roller 214 and the third cutting drive 213 to move together with the third transfer seat 212. The third cutter 215 is mounted on the drive end of the third cutting drive 213, enabling the third cutting drive 213 to drive the third cutter 215 to cut the work material strip a1 that has passed around the second guide roller 214. Thus, the third moving drive 211 drives the third transfer seat 212 to move, thereby moving the second guide roller 214, causing the working material belt a1 to pass around the second guide roller 214. In other words, the second guide roller 214 guides the conveying path of the working material belt a1, ensuring that the working material belt a1 passes between the two adhesive rollers 31. The third cutting drive 213 drives the third cutter 215 to cut the working material belt a1 that has passed around the second guide roller 214. Optionally, the third moving drive 211 can be a cylinder. The third cutting drive 213 can also be a cylinder.

[0088] Furthermore, the third cutter 215 is located downstream of the second roller 214, that is, the third cutter 215 is located on the side of the second roller 214 facing the adhesive roller 31, thereby ensuring that the downstream cut end a11 of the working material strip a1 formed by the third cutter 215 cutting the working material strip a1 is close enough to the adhesive roller 31, thereby ensuring that when the two adhesive rollers 31 rotate in opposite directions, the adhesive strip B on the two adhesive rollers 31 can be adhered to the downstream cut end a11 of the working material strip a1 and the upstream cut end a21 of the spare material strip a2, that is, ensuring that the strip is spliced.

[0089] 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.

[0090] 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.
