Description

Technical Field

[0001] This invention relates to the field of battery production equipment technology, and more specifically, to an automatic winding device and a winding machine. Background Technology

[0002] In related technologies, the winding machine is equipped with two rolls: a working roll and a spare roll. When the strip on the working roll is almost used up, it needs to be cut and the tail of the working strip needs to be connected to the head of the spare roll. However, in these technologies, roll changing mainly relies on manual operation or semi-automatic equipment. Typically, the operator needs to pause the winding machine and manually splice the tail of the used working roll and the head of the spare roll together with tape before restarting the winding machine. This method requires stopping the machine every time a roll is changed, interrupting production continuity and severely impacting the utilization rate and production efficiency of the winding machine. Furthermore, the strength and alignment accuracy of manual splicing are difficult to guarantee, easily leading to problems such as strip breakage, wrinkles, and misalignment during subsequent high-speed traction, resulting in material waste and defective products. Moreover, manual operation near high-speed running equipment poses certain safety risks. Summary of the Invention

[0003] The present invention aims to provide an automatic roll changing device and a winding machine. The automatic roll changing device has a high degree of automation, stable splicing quality of the strip, and low safety risk during use.

[0004] To address the above problems, the first aspect of the present invention provides an automatic roll changing device, comprising:

[0005] An unwinding mechanism, comprising a lifting component, which is movable between two spaced-apart feeding mechanisms, one of which is used to unwind a working strip and the other is used to unwind a spare strip, the lifting component being used to pick up the head of the spare strip;

[0006] A waste collection mechanism is provided near the unwinding mechanism. The waste collection mechanism is used to receive the head of the spare material strip and pull the spare material strip. The waste collection mechanism is also used to remove the waste spare material strip.

[0007] A tape-connecting mechanism is used to cut the spare tape to be connected and the working tape to be connected, and to join and fix the cut end of the spare tape and the cut end of the working tape.

[0008] Furthermore, the unwinding mechanism includes a first moving module, a second moving module, and a lifting assembly;

[0009] The lifting component is mounted on the first moving module, and the first moving module is used to drive the lifting component to move along the second direction, so that the lifting component can move toward the waste collection mechanism.

[0010] The first moving module is mounted on the second moving module, which drives the lifting component to move along a first direction, so that the lifting component moves between the two feeding mechanisms to pick up the head of the spare material strip.

[0011] Furthermore, the lifting assembly includes two sets of clamping members arranged along a first direction. Each clamping member includes a lifting suction cup and a lifting clamping plate. The suction surface of the lifting suction cup faces the lifting clamping plate. The lifting suction cup is used to suction the head of the spare material strip. The lifting clamping plate can move toward the lifting suction cup so that the lifting clamping plate and the lifting suction cup together clamp the head of the spare material strip.

[0012] Furthermore, the waste collection mechanism includes a strip winding assembly, a third moving module, and a fourth moving module;

[0013] The strip take-up assembly is mounted on the third moving module. The third moving module is used to drive the strip take-up assembly to move along the first direction, so that the strip take-up assembly moves between the two unwinding mechanisms to get closer to the spare strip in the two unwinding mechanisms.

[0014] The fourth moving module is used to drive the third moving module to move in a third direction, so that the strip winding assembly can move toward the spare strip to wind up the head of the spare strip and pull the spare strip.

[0015] Furthermore, the strip winding assembly includes a waste collection shaft and a waste collection drive. The waste collection shaft has a gap through which the spare strip can be inserted, and the waste collection drive is used to drive the waste collection shaft to rotate, so that the waste collection shaft winds up the spare strip.

[0016] Furthermore, the waste collection mechanism also includes a waste collection assembly, which includes a waste scraper and a waste collection box. The waste collection scraper is disposed on one side of the waste collection shaft and is used to remove the waste spare material strip on the waste collection shaft. The waste collection box is disposed below the waste collection shaft and is used to collect the waste spare material strip.

[0017] Furthermore, the tape-connecting mechanism includes a glue-preparing mechanism and a cutting mechanism. The cutting mechanism is used to cut the spare tape and the working tape. The two glue-preparing mechanisms are arranged opposite to each other, and the working tape and the spare tape are arranged between the two glue-preparing mechanisms. The two glue-preparing mechanisms can move relative to each other in a first direction to adsorb the spare tape and the working tape to be connected, and to join and fix the spare tape and the working tape to be connected.

[0018] Furthermore, the adhesive preparation mechanism includes an adhesive receiving tray, an adhesive preparation suction cup, a first exchange belt suction cup, and a second exchange belt suction cup;

[0019] The splicing tape is placed and rolled on the splicing tape reel;

[0020] The adhesive suction cup is used to absorb the prepared adhesive tape.

[0021] The first and second exchange belt suction cups are arranged side by side. Both the first and second exchange belt suction cups are used to adsorb working material belts or spare material belts. There is a gap between the first and second exchange belt suction cups. The first exchange belt suction cup is located above the second exchange belt suction cup. The glue preparation suction cup is located on the side of the first exchange belt suction cup, and the included angle between the glue preparation suction cup and the first exchange belt suction cup is 90°.

[0022] Furthermore, it also includes a diameter detector and a positioning sensor;

[0023] The diameter detection sensor is located close to the feeding mechanism. The diameter detection sensor is used to detect the diameter of the spare material strip. The diameter detection sensor is electrically connected to the second moving module. The second moving module moves to a predetermined position according to the diameter signal detected by the diameter detection sensor.

[0024] The positioning sensor is used to detect the head of the spare material strip. The feeding mechanism is electrically connected to the positioning sensor. The feeding mechanism rotates according to the head signal detected by the positioning sensor, so that the head of the spare material strip rotates to be close to the lifting assembly.

[0025] A second aspect of the present invention provides a winding machine including an automatic winding device as described in the first aspect.

[0026] The automatic roll-changing device and winding machine of this invention, by setting a lifting component between two unloading mechanisms, can automatically unwind the head of the spare material strip. The waste collection mechanism receives the head of the spare material strip and pulls it, enabling the splicing mechanism to cut the spare material strip into spare material strips to be spliced ​​and working material strips to be spliced. The splicing mechanism joins and fixes the cut ends of the spare material strip and the working material strip. The spliced ​​new material strip is automatically unwound for cell production, while the waste spare material strip is removed by the waste collection mechanism. This achieves automatic roll-changing of material strips, reduces manual operation, and does not require machine downtime during roll-changing, enabling continuous cell production and improving production efficiency. In addition, the automatic unwinding of the head of the spare material strip is stable and highly consistent, reducing the risk of damage to the electrode sheets. The automatic splicing improves the splicing stability and consistency of the working and spare material strips, reducing or avoiding quality defects such as strip breakage and wrinkles caused by poor splicing, which is beneficial to improving the quality of the cell. The automatic roll changing device of the present invention can provide high-precision and high-reliability automatic roll changing, which can adapt to the requirements of high-speed and wide-width modern production lines. At the same time, it can also reduce the intensity of manual operation and safety hazards, realize unmanned operation in the roll changing area, and meet the requirements of intelligent manufacturing.

[0038] Combination Figure 1 As shown, a first aspect of this embodiment provides an automatic roll changing device, including: an unwinding mechanism, a waste collection mechanism 30, and a tape receiving mechanism, wherein:

[0039] The unwinding mechanism includes a lifting component 21, which can move between two spaced-apart feeding mechanisms 10. One of the two feeding mechanisms 10 is used to unwind the working material strip 1, and the other is used to unwind the spare material strip 2. The lifting component 21 is used to pick up the head of the spare material strip 2.

[0040] The waste collection mechanism 30 is located near the unwinding mechanism. The waste collection mechanism 30 is used to receive the head of the spare material belt 2 and pull the spare material belt 2. The waste collection mechanism 30 is also used to remove the waste spare material belt 2.

[0041] The tape splicing mechanism is used to cut the spare tape 2 and the working tape 1 that need to be spliced, and to join and fix the cut ends of the spare tape 2 and the working tape 1.

[0042] The automatic roll-changing device provided in this embodiment, by setting a lifting component between two unloading mechanisms, can automatically unwind the head of the spare material strip. The waste collection mechanism receives the head of the spare material strip and pulls it, enabling the splicing mechanism to cut the spare material strip into spare material strips to be spliced ​​and working material strips to be spliced. The splicing mechanism joins and fixes the cut ends of the spare material strip and the working material strip. The new material strip after splicing is automatically unwound for cell production, while the waste spare material strip is removed by the waste collection mechanism. This achieves automatic roll-changing of material strips, reduces manual operation, and does not require machine downtime during roll-changing, enabling continuous cell production and improving production efficiency. In addition, the automatic unwinding of the head of the spare material strip is stable and highly consistent, reducing the risk of damage to the electrode sheets. The automatic splicing improves the splicing stability and consistency of the working and spare material strips, reducing or avoiding quality defects such as strip breakage and wrinkles caused by poor splicing, which is beneficial to improving the quality of the cell. The automatic roll changing device of the present invention can provide high-precision and high-reliability automatic roll changing, which can adapt to the requirements of high-speed and wide-width modern production lines. At the same time, it can also reduce the intensity of manual operation and safety hazards, realize unmanned operation in the roll changing area, and meet the requirements of intelligent manufacturing.

[0043] In this embodiment, two unwinding mechanisms 10 are arranged side by side, with a certain distance between them. The unwinding of the working material strip 1 and the spare material strip 2 by these two unwinding mechanisms 10 is relative. That is, when one unwinding mechanism 10 is used to place the working material strip 1 and unwind the working material strip 1, the other unwinding mechanism is used to place the spare material strip 2 and unwind the spare material strip 2.

[0044] Based on the above embodiments, as an optional implementation, the unwinding mechanism further includes a first moving module 22 and a second moving module 23; wherein, the lifting component 21 is disposed on the first moving module 22, and the first moving module 22 is used to drive the lifting component 21 along the longitudinal direction (i.e., the second direction). Figure 1 The first moving module 22 is mounted on the second moving module 23, which is used to move the lifting assembly 21 toward the waste collection mechanism 30 so that the waste collection mechanism 30 can receive the spare material strip 2 picked up by the lifting assembly 21; the first moving module 22 is mounted on the second moving module 23, and the second moving module 23 is used to drive the first moving module 22 along the lateral direction (i.e., the first direction). Figure 1The lifting assembly 21 moves between the two feeding mechanisms 10 to pick up the head of the spare material strip 2. Thus, by setting the second moving module 23, the lifting assembly 21 can move between the two feeding mechanisms 10 to unwind the spare material strip 2 on the two feeding mechanisms 10. By setting the first moving module 22, the lifting assembly 21 can move between the feeding mechanism 10 and the waste collection mechanism 30, so that the waste collection mechanism 30 receives the head of the spare material strip 2 and pulls the spare material strip 2, facilitating its subsequent connection to the working material strip 1.

[0045] Based on the above embodiments, as an optional implementation, the first moving module 22 and the second moving module 23 can be driven by a motor or a cylinder, and can be coupled with transmission components such as lead screws or guide rails.

[0046] Based on the above embodiments, as an optional implementation method, combined with Figures 2 to 4 As shown, the lifting assembly 21 includes two sets of clamping members arranged in the transverse direction. Each set of clamping members includes a lifting suction cup 211 and a lifting clamping plate 212. The suction surface of the lifting suction cup 211 faces the lifting clamping plate 212. The lifting suction cup 211 is used to suction the head of the spare material strip 2. The lifting clamping plate 212 can move toward the lifting suction cup 211, so that the lifting clamping plate 212 and the lifting suction cup 211 jointly clamp the head of the spare material strip 2. Thus, by setting the lifting suction cup 211 and the lifting clamping plate 212, after the lifting suction cup 211 suctions the head of the spare material strip 2, the lifting clamping plate 212 moves toward the lifting suction cup 211, so that the lifting clamping plate 212 and the lifting suction cup 211 jointly clamp the head of the spare material strip 2 to unwind the spare material strip 2. The cooperation of the lifting suction cup 211 and the lifting clamping plate 212 can improve the stability of clamping the head of the spare material strip 2. By setting two sets of clamping components, the two sets of clamping components can unwind the two unwinding mechanisms 10 respectively, which can meet the unwinding requirements on both the left and right sides.

[0047] Specifically, the lifting assembly 21 also includes a lifting clamping gripper 213 and a lifting drive component 214. The lifting clamping gripper 213 is connected to the lifting clamping plate 212 and is used to drive the lifting clamping plate 212 to move laterally, bringing the lifting clamping plate 212 closer to the lifting suction cup 211, so that the lifting clamping plate 212 cooperates with the lifting suction cup 211 to clamp the head of the spare material strip 2, or to move the lifting clamping plate 212 away from the lifting suction cup 211, so that the lifting clamping plate 212 releases the head of the spare material strip 2. The lifting drive component 214 is connected to the lifting clamping gripper 213 and is used to drive the lifting clamping gripper 213 to move longitudinally, so that the lifting clamping plate 212 is positioned opposite to the lifting suction cup 211. Therefore, by connecting the lifting drive 214 to the lifting clamping gripper 213, when the lifting drive 214 drives the lifting clamping gripper 213 to move in the longitudinal direction, it can drive the lifting clamping plate 212 to move in the longitudinal direction, so that the lifting clamping plate 212 is positioned opposite to the lifting suction cup 211. Then, the lifting clamping gripper 213 drives the lifting clamping plate 212 to move in the transverse direction, so that the lifting clamping plate 212 and the lifting suction cup 211 cooperate to clamp the head of the material roll. The lifting drive component 214 can adjust the height of the lifting clamp 212 in the longitudinal direction. Before the lifting suction cup 211 adsorbs the head of the spare material strip 2, the lifting drive component 214 can adjust the lifting clamp 212 to be higher than the lifting suction cup 211 to avoid the lifting suction cup 211 adsorbing the head of the spare material strip 2. After the lifting suction cup 211 adsorbs the head of the spare material strip 2, the lifting drive component 214 can adjust the lifting clamp 212 to the same height as the lifting suction cup 211, so that the lifting drive component 214 and the lifting clamp 212 can cooperate to clamp the head of the spare material strip 2. As an optional embodiment, the lifting drive component 24 is a cylinder, and the cylinder rod is connected to the lifting clamp gripper 23.

[0048] The lifting assembly 21 also includes a vacuum box 215, which is connected to the lifting drive 214 and the lifting suction cup 211. The vacuum box 215 provides a vacuum to the lifting suction cup 211, allowing it to adsorb the head of the spare material strip 2. The vacuum box 215 can be connected to the cylinder body of a cylinder, and its position remains unchanged when the lifting drive 214 drives the lifting clamp 213 to move longitudinally. Therefore, by providing a vacuum to the lifting suction cup 211 through the vacuum box 215, the reliability and stability of the lifting suction cup 211 in adsorbing the head of the material roll can be improved. The vacuum box 215 can also be connected to an external vacuum generator, which generates a vacuum and provides it to the lifting suction cup 211 through the vacuum box 215.

[0049] Based on the above embodiments, as an optional implementation method, combined with Figures 5 to 8As shown, the waste collection mechanism 30 includes a strip winding assembly 31, a third moving module 32, and a fourth moving module 33. The strip winding assembly 31 is mounted on the third moving module 32, which drives the strip winding assembly 31 to move laterally, allowing it to move between the two unwinding mechanisms 10 to approach the spare strip 2 within each unwinding mechanism 10. The fourth moving module 33 drives the third moving module 32 in the inward / outward direction (i.e., the third direction). Figure 2 The material take-up assembly 31 moves towards the spare material strip 2 (in the y-axis direction, i.e., perpendicular to the screen) to move along the y-axis direction, so as to take up the head of the spare material strip 2 and pull the spare material strip 2. Thus, by setting the third moving module 32, the material take-up assembly 31 can move between the two unloading mechanisms 10 to cooperate with the lifting assembly 21 to receive the spare material strip 2 on the corresponding unloading mechanism 10. By setting the fourth moving module 33, the material take-up assembly 31 can extend to take up the spare material strip 2.

[0050] Based on the above embodiments, as an optional implementation, the third moving module 32 can be driven by a cylinder and cooperated with transmission components such as a lead screw or guide rail. The third moving module 32 is mounted on the fourth moving module 33 via a slider. The fourth moving module 33 is powered by a motor, which rotates a belt to drive the belt to rotate. The belt is connected to the slider, causing the slider to move in the inward and outward directions, thereby driving the third moving module 32 and the strip winding assembly 31 mounted thereon to move in the inward and outward directions.

[0051] Based on the above embodiments, as an optional implementation, the strip winding assembly 31 includes a waste collection shaft 311 and a waste collection drive 312. The waste collection shaft 311 has a gap 3111 through which the spare strip 2 can be inserted. The waste collection drive 312 is used to drive the waste collection shaft 311 to rotate, so that the waste collection shaft 311 winds up the spare strip 2. Thus, by providing the gap 3111 on the waste collection shaft 311, the spare strip 2 can be inserted into the gap 3111 of the waste collection shaft 311. During the process of the waste collection drive 312 driving the waste collection shaft 311 to rotate, the waste collection shaft 311 can wind up the spare strip 2 and pull the head of the spare strip 2.

[0052] Based on the above embodiments, as an optional implementation, the strip winding assembly 31 further includes a waste collection roller 313. The waste collection roller 313 and the waste collection shaft 311 are arranged opposite to each other, and the waste collection roller 313 can move close to the waste collection shaft 311 or move away from the waste collection shaft 311. So when the waste collection roller 313 moves close to the waste collection shaft 311, the waste collection roller 313 can press against the waste collection shaft 311 to prevent the waste collection shaft 311 from continuing to wind the spare strip 2 and avoid wasting too much spare strip 2.

[0053] Based on the above embodiments, as an optional implementation, the waste collection mechanism 30 further includes a waste collection assembly, which includes a waste scraper 34 and a waste collection box 35. The waste scraper 34 is disposed on one side of the waste collection shaft 311 and is used to remove the waste spare material strip 2 on the waste collection shaft 311. The waste collection box 35 is disposed below the waste collection shaft 311 and is used to collect the waste spare material strip 2. Thus, after the spare material strip 2 and the working material strip 1 are rewound, the waste scraper 34 moves toward the waste collection shaft 311 and makes tangential contact with the waste collection shaft 311, scraping off the excess spare material strip 2 wound on the waste collection shaft 311. The scraped-off waste spare material strip 2 falls into the waste collection box 35 to collect the waste spare material strip 2.

[0054] Based on the above embodiments, as an optional implementation, the tape-connecting mechanism includes a glue preparation mechanism 41 and a cutting mechanism (not shown in the figure). The cutting mechanism is used to cut the spare material tape 2 and the working material tape 1. The two glue preparation mechanisms 41 are arranged opposite to each other, and the working material tape 1 and the spare material tape 2 are arranged between the two glue preparation mechanisms 41. The two glue preparation mechanisms 41 can move relative to each other in the lateral direction to adsorb the spare material tape 2 and the working material tape 1 that need to be connected, and to join and fix the spare material tape 2 and the working material tape 1 that need to be connected.

[0055] Specifically, in combination Figure 9As shown, the adhesive preparation mechanism 41 includes a tape receiving tray 411, an adhesive preparation suction cup 412, a first exchange tape suction cup 413, and a second exchange tape suction cup 414. The tape receiving tray 411 holds and holds a roll of tape receiving adhesive paper, which is then fed onto the adhesive preparation suction cup 412 via a winding roller, with the adhesive side facing upwards. The adhesive preparation suction cup 412 is used to absorb the prepared tape receiving adhesive paper. The first exchange tape suction cup 413 and the second exchange tape suction cup 414 are arranged side-by-side with a gap between them. The first exchange tape suction cup 413 is positioned above the second exchange tape suction cup 414. Both the first and second exchange tape suction cups 413 and 414 are used to absorb the working tape 1 or the spare tape 2. The adhesive preparation suction cup 412 is positioned to the side of the first exchange tape suction cup 413, and the angle between the adhesive preparation suction cup 412 and the first exchange tape suction cup 413 is 90°. In this embodiment, the adhesive preparation suction cup 412 uses vacuum adsorption to attach the adhesive tape, and the first exchange tape suction cup 413 and the second exchange tape suction cup 414 both use vacuum adsorption to attach the working tape 1 or the spare tape 2. The adhesive preparation mechanism 41 also includes a tape-attaching lateral movement drive 415 and a suction cup flipping drive 416. The tape-attaching lateral movement drive 415 is used to drive the adhesive preparation suction cup 412, the first exchange tape suction cup 413, and the second exchange tape suction cup 414 to move laterally, so that the first exchange tape suction cup 413 or the second exchange tape suction cup 414 adsorbs the spare tape 2 or the working tape 1 that needs to be attached. The suction cup flipping drive 416 is used to drive the adhesive preparation suction cup 412 to flip 90°, so that the adhesive surface of the adhesive tape adsorbed on the adhesive preparation suction cup 412 faces the spare tape 2 or the working tape 1 that needs to be attached, so that the subsequent tape attaching will join and fix the spare tape 2 and the working tape 1 that need to be attached. As an alternative implementation, the transverse drive 415 can be a cylinder, and the suction cup flip drive 416 can be a flip cylinder.

[0056] Therefore, by arranging the first exchange tape suction cup 413 and the second exchange tape suction cup 414 side by side with a gap between them, one of the two exchange tape suction cups can adsorb the required tape (including working tape 1 or spare tape 2), and the other can adsorb the discarded tape (including discarded working tape 1 or discarded spare tape 2), so that the splicing adhesive tape can be used to join and fix the required tape. By placing the adhesive preparation suction cup 412 on the side of the first exchange tape suction cup 413, and by allowing the adhesive preparation suction cup 412 to be flipped so that the splicing adhesive tape can join the working tape 1 to be joined and the spare tape 2 to be joined, the overall structure of the adhesive preparation mechanism 41 becomes more compact.

[0057] Based on the above embodiments, as an optional implementation, the automatic roll changing device further includes a diameter detection sensor 50. The diameter detection sensor 50 is disposed near the unloading mechanism 10 and is used to detect the diameter of the spare material strip 2. The diameter detection sensor 50 is electrically connected to the second moving module 23. The second moving module 23 moves to a predetermined position according to the diameter signal detected by the diameter detection sensor 50, so that the lifting assembly 21 can pick up the head of the spare material strip 2 on the unloading mechanism 10.

[0058] Based on the above embodiments, as an optional implementation, the automatic roll changing device further includes a positioning sensor 60, which is used to detect the head of the spare material strip 2. The feeding mechanism 10 is electrically connected to the positioning sensor 60. The feeding mechanism 10 rotates according to the head signal detected by the positioning sensor 60, so that the head of the spare material strip 2 rotates to be close to the lifting assembly 21, so that the lifting assembly 21 can pick up the head of the spare material strip 2 on the feeding mechanism 10.

[0059] Based on the above embodiments, as an optional implementation, the automatic roll changing device also includes a tail mark detector (not shown in the figure). The tail mark detector is located near the unloading mechanism 10. The tail mark detector is used to detect whether the working material belt 1 has been unwound, so that the two glue preparation mechanisms 41 can connect and fix the spare material belt 2 that needs to be connected and the working material belt 1 that needs to be connected, so that the spare material belt 2 is connected to the tail of the working material belt 1.

[0060] Based on the above embodiments, as an optional implementation, the automatic roll changing device further includes a pressing mechanism 70. The pressing mechanism 70 is located near the waste collection mechanism 30 and is used to press down the working tape 1. This presses down the working tape 1 when the spare tape 2 to be joined and fixed with the working tape 1, preventing any impact on the strength and alignment accuracy of the splicing process between the working tape 1 and the spare tape 2. This embodiment does not further limit the specific structure of the pressing mechanism 70; those skilled in the art can select a commonly used pressing mechanism 70 according to the actual situation.

[0061] The second aspect of this embodiment provides a winding machine that includes the automatic roll changing device described in the first aspect. This winding machine provides high-precision, high-reliability automatic roll changing, adapting to the requirements of high-speed, wide-width modern production lines. It also reduces manual labor intensity and safety hazards, enabling unmanned operation in the roll changing area and meeting the requirements of intelligent manufacturing.

[0062] The following combination Figures 1 to 9 The working principle of the automatic winding device and winding machine provided by the present invention will be explained as follows:

[0063] like Figure 1The unwinding mechanism 10 on the left is used to unwind the spare material strip 2, and the unwinding mechanism 10 on the right is used to unwind the working material strip 1. The working material strip 1 is unwound normally during production. When the working material strip 1 is almost used up, the diameter detection sensor 50 detects the diameter of the spare material strip 2. At the same time, after the positioning sensor 60 detects the head of the spare material strip 2, the unwinding mechanism 10 rotates the head of the spare material strip 2 to be close to the unwinding mechanism. Then, the lifting assembly 21 is moved to be close to the head of the spare material strip 2 through the first moving module 22 and the second moving module 23. The lifting clamp 212 and the lifting suction cup 211 on the lifting assembly 21 jointly clamp the head of the spare material strip 2 and unwind the spare material strip 2. After the spare material strip 2 is unwound, the lifting assembly 21 is moved to the waste collection mechanism 30 by the first moving module 22 and the second moving module 23. During the movement, the lifting assembly 21 pulls the spare material strip 2 to the waste collection mechanism 30. Then, the third moving module 32 drives the material strip winding assembly 31 to move in the lateral direction, so that the material strip winding assembly 31 is close to the unwinding mechanism 10 on the left. The fourth moving module 33 drives the material strip winding assembly 31 to move outward, so that the waste collection shaft 311 moves outward. At the same time, the direction of the gap 3111 on the waste collection shaft 311 is adjusted to be parallel to the spare material strip 2, so that the gap 3111 of the waste collection shaft 311 is inserted into the head of the spare material strip 2, and the waste collection shaft 311 is driven to wind the spare material strip 2 and pull the head of the spare material strip 2.

[0064] Subsequently, the adhesive tape on the left and right glue preparation mechanisms 41 is fed onto the glue preparation suction cup 412 via the winding roller, so that the adhesive side of the adhesive tape faces upwards, and the two glue preparation mechanisms 41 move relative to each other in the lateral direction. Specifically, the first exchange tape suction cup 413 and the second exchange tape suction cup 414 on the left glue preparation mechanism 41 vacuum-adsorb the spare material tape 2, and the first exchange tape suction cup 413 and the second exchange tape suction cup 414 on the right glue preparation mechanism 41 vacuum-adsorb the working material tape 1. After the working material tape 1 on the right unwinding mechanism 10 is unwound, the pressing mechanism 70 presses the working material tape 1... The tape is pressed, and the cutting mechanism cuts the spare tape 2 and the working tape 1, resulting in two parts: a discarded spare tape 2 and a spare tape 2 to be joined. The first exchange tape suction cup 413 on the left-side glue preparation mechanism 41 picks up the discarded spare tape 2, and the second exchange tape suction cup 414 picks up the spare tape 2 to be joined. This also results in two parts: a working tape 1 to be joined and a discarded working tape 2. Similarly, the first exchange tape suction cup 413 on the right-side glue preparation mechanism 41 picks up the working tape 1 to be joined, and the second exchange tape suction cup 414 picks up the working tape 1 to be joined. Subsequently, the discarded spare tape 2 and the discarded working tape 1 are de-adsorbed; that is, only the second exchange tape suction cup 414 on the left-side glue preparation mechanism 41 picks up the spare tape 2 to be joined, and only the first exchange tape suction cup 413 on the right-side glue preparation mechanism 41 picks up the working tape 1 to be joined. Subsequently, the glue preparation suction cups 412 on the left and right glue preparation mechanisms 41 are rotated 90°, so that the adhesive surface of the adhesive tape adsorbed on the two glue preparation suction cups 412 faces the spare material belt 2 or the working material belt 1 that needs to be connected. Then, the two glue preparation mechanisms 41 move relative to each other in the lateral direction, and the spare material belt 2 and the working material belt 1 that need to be connected are joined and fixed by the adhesive tape, so that the spare material belt 2 is connected to the end of the working material belt 1.

[0065] After the spare material strip 2 and the working material strip 1 are connected, there will be an excess spare material strip 2 on the waste collection shaft 311. The waste collection pressure roller 313 moves close to the waste collection shaft 311, and the waste collection shaft 311 rotates to collect the remaining length of spare material strip 2. Subsequently, the fourth moving module 33 drives the material strip winding assembly 31 to move inward, causing the waste collection shaft 311 to move inward. During the movement of the waste collection shaft 311, the waste scraper 34 moves toward the waste collection shaft 311, so that the waste scraper 34 makes tangential contact with the waste collection shaft 311. The waste collection pressure roller 313 moves away from the waste collection shaft 311, releasing the waste collection shaft 311. As the waste collection shaft 311 continues to move inward, the waste scraper 34 scrapes off the excess spare material strip 2 wound on the waste collection shaft 311. The scraped-off waste spare material strip 2 falls into the waste collection box 35 to collect the waste spare material strip 2. After the excess spare material belt 2 on the waste collection shaft 311 is cleaned up, the waste collection shaft 311 is reset.
