[0031] The following will clearly and completely describe the concept, specific structure and technical effects of the present invention in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the fact that a better connection structure can be formed by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the invention can be combined interactively without conflicting with each other.

[0032] Please refer to Figures 1 to 3 An embodiment of the present invention provides a multifunctional glue preparation and application mechanism, which includes a mounting platform 1, two glue preparation and application modules, and a glue pulling drive module 90.

[0033] The front end of the mounting platform 1 is arranged on the rear side of the large plate 2 of the frame.

[0034] Two adhesive preparation and application modules are installed on the mounting platform 1 and the large plate 2, and are symmetrically distributed. The two adhesive preparation and application modules are used to apply adhesive tape to both sides of the connection point between the new and old electrode pieces, both sides of the electrode piece cutting point, both sides of the electrode piece corners, and both sides of the electrode piece tabs. It can be understood that the number of adhesive preparation and application modules can be set according to actual conditions.

[0035] Specifically, the glue preparation and gluing module includes a material discharge rubber disc module 10, a glue laminating module 30, a glue pulling module 40, a tape cutting module 50, a support module 60, a glue transferring and patting module 70 and a glue shuttle transferring module 80. Therefore, the material discharge rubber disc module 10, the glue laminating module 30, the glue pulling module 40, the tape cutting module 50, the support module 60, the glue transferring and patting module 70 and the glue shuttle transferring module 80 of the present invention are two respectively, and the two material discharge rubber disc modules 10, the two glue laminating modules 30, the two glue pulling modules 40, the two tape cutting modules 50, the two support modules 60, the two glue transferring and patting modules 70 and the two glue shuttle transferring modules 80 are respectively distributed symmetrically on the left and right.

[0036] The unloading rubber disc module 10 is used to supply the adhesive tape 200. Figure 4 and Figure 5 As shown, the unloading rubber disc module 10 includes a unloading rubber disc substrate 11, a material disc assembly 12, a tape buffer assembly 13, a tape pressing assembly 14, a tape redirecting assembly and a sensor assembly.

[0037] The unloading rubber tray substrate 11 is L-shaped, the horizontal portion of the unloading rubber tray substrate 11 is vertically arranged on the back of the mounting platform 1 and corresponds to the rear end of the mounting platform 1, and the vertical portion of the unloading rubber tray substrate 11 is located behind the mounting platform 1.

[0038] The tray assembly 12 is used to mount the adhesive tape 200. Specifically, the tray assembly 12 includes a hanging shaft 121 and a tray 122 for mounting the adhesive tape 200. A through-hole is provided in the transverse portion of the unloading adhesive tape base plate 11. The hanging shaft 121 extends through the through-hole. A bearing is positioned within the through-hole and is sleeved around the outer periphery of the hanging shaft 121. The bearing allows the hanging shaft 121 to rotate relative to the unloading adhesive tape base plate 11. The tray 122 sleeves around the outer periphery of the hanging shaft 121.

[0039] In this embodiment, the material tray 122 has an installation groove for installing the adhesive tape 200. The hanging shaft 121 is a hanging shaft with self-damping, so that it can provide tension to the unwound adhesive tape 200.

[0040] The tape buffer assembly 13 is located behind the material tray assembly 12. The tape buffer assembly 13 is used to buffer the tape 200 on the material tray assembly 12. The tape buffer assembly 13 includes a buffer driver 131, a first buffer roller 132, a second buffer roller 133, a third buffer roller 136, a buffer slide 134, and a buffer slide 135. The buffer driver 131 is arranged on the outside of the vertical portion of the unloading rubber tray substrate 11 (the outside is the side of the vertical portion of the unloading rubber tray substrate 11 away from the center of the mounting platform 1). The buffer driver 131 is a cylinder. One end of the first buffer roller 132 and one end of the second buffer roller 133 are arranged on the outside of the vertical portion of the unloading rubber tray substrate 11. The buffer slide 134 is arranged on the outside of the vertical portion of the unloading rubber tray substrate 11. The length direction of the buffer slide 134 is the same as the height direction of the unloading rubber tray substrate 11. The first cache roller 132 and the second cache roller 133 are respectively located on both sides of the cache slide 134 and correspond to the top of the cache slide 134. The first cache roller 132 and the second cache roller 133 are arranged in parallel front and back. The cache slide 135 is slidably matched with the cache slide 134, and the front end of the cache slide 135 is connected to the output end of the cache driver 131 through a cache connector (not shown in the figure). One end of the third cache roller 136 is arranged on the side of the cache slide 135 away from the cache slide 134. The cache driver 131 is used to drive the cache slide 135 to slide up and down along the cache slide 134, thereby driving the third cache roller 136 to move up and down. In actual use, the adhesive tape 200 on the material tray 122 passes over the first buffer roller 132, under the third buffer roller 136, and in front of the second buffer roller 133. The third buffer roller 136 is driven downward by the buffer driver 131. During the downward movement of the third buffer roller 136, the third buffer roller 136 can pull the adhesive tape 200. Driven by the pulling force of the adhesive tape 200, the material tray 122 and the hanging shaft 121 can be rotated. The rotation of the material tray 122 can thereby realize the unwinding of the adhesive tape 200 on the material tray 122. In this way, the adhesive tape 200 can be pulled out to a predetermined length by the third buffer roller 136, thereby realizing the caching of the adhesive tape 200. The length of the cached adhesive tape 200 is the same as the length of the adhesive tape 200 pulled out by the adhesive drawing module 40. The adhesive tape 200 is installed by the tray assembly 12 and the adhesive tape 200 on the tray assembly 12 is cached by the tape cache assembly 13, thereby realizing the supply of the adhesive tape 200.

[0041] A support roller 17 is provided between the material tray 122 and the first buffer roller 132 to support the adhesive tape 200. One end of the support roller 17 is positioned outside the vertical portion of the unloading rubber tray base 11. In actual use, the adhesive tape 200 on the material tray 122 first passes under the support roller 17 and then passes over the first buffer roller 132.

[0042] The tape compression assembly 14 is located above and behind the tape buffer assembly 13. The tape compression assembly 14 is used to compress the tape 200 after the tape cutting module 50 cuts the tape 200. The tape compression assembly 14 includes a compression driver 142, a pressure block 143, and a compression roller 141. One end of the compression roller 141 is located outside the vertical portion of the unloading rubber disc substrate 11. The compression driver 142 is a cylinder, which is located outside the vertical portion of the unloading rubber disc substrate 11 through a cylinder seat and behind the compression roller 141. The pressure block 143 is located at one end of the compression driver 142 near the pressure roller 141 and opposite to the pressure roller 141. The compression driver 142 is used to drive the pressure block 143 to move toward or away from the pressure roller 141. In actual application, the tape 200 passes over the second cache roller 133 and then passes behind the pressing roller 141. After the tape cutting module 50 cuts the tape 200, the pressing block 143 is driven by the pressing drive 142 to move toward the pressing roller 141, so that the tape 200 can be pressed on the pressing roller 141, thereby achieving the compression of the tape 200.

[0043] In this embodiment, the support roller 17, the first buffer roller 132, the second buffer roller 133, the third buffer roller 136, and the pressure roller 141 each include a roller shaft and a roller sleeve rotatably mounted on the outer periphery of the roller shaft. One end of the roller shaft is positioned outside the vertical portion of the unloading rubber disc base plate 11. Rotary bearings are located at each end of the roller sleeve, which is mounted on the outer periphery of the roller shaft, thereby rotatably mounting the roller sleeve on the outer periphery of the roller shaft. In actual use, the adhesive tape 200 on the material disc 122 first passes under the roller sleeve of the support roller 17, then passes over the roller sleeve of the first buffer roller 132, under the roller sleeve of the third buffer roller 136, in front of the roller sleeve of the second buffer roller 133, and behind the roller sleeve of the pressure roller 141.

[0044] The tape redirection assembly is located above the tray assembly 12 and is used to change the direction of the tape 200 from vertical to horizontal. The tape redirection assembly includes a spring roller 151, which is located above the tray assembly 12 and in front of the vertical portion of the unloading rubber tray base plate 11. The spring roller 151 corresponds to the pressure roller 141. In actual use, the tape 200 passes behind the pressure roller 141 and then below the spring roller 151. This allows the spring roller 151 to change the direction of the tape 200 from vertical to horizontal, facilitating the clamping module 30 to clamp the tape head of the tape 200.

[0045] In this embodiment, the spring roller 151 includes a roller main shaft 1512, a roller sleeve 1511 rotatably mounted on the outer periphery of the roller main shaft 1512, a spring 1513, and a roller connecting shaft 1514. Roller bearings are provided at each end of the roller sleeve 1511. The roller bearings are mounted on the outer periphery of the roller main shaft 1512, thereby rotatably mounting the roller sleeve on the outer periphery of the roller main shaft 1512. The roller sleeve is located above the material tray 122 and corresponds to the pressing roller 141. A limit member 15111 is detachably mounted on the first end of the roller main shaft 1512. The limit member 15111 has a mounting hole, in which a fastener, such as a screw, is mounted. The end of the fastener abuts against the outer periphery of the roller main shaft 1512. The second end of the roller main shaft 1512 is connected to one end of the roller connecting shaft 1514. The other end of the roller connecting shaft 1514 extends through the first roller mounting seat 153. The rear side of the first roller mounting seat 153 is connected to the roller mounting shaft 152. The roller mounting shaft 152 is mounted on the inner side of the vertical portion of the unloading rubber disc base plate 11 (the inner side is the side of the vertical portion of the unloading rubber disc base plate 11 closer to the center of the mounting platform 1) through the second roller mounting seat (not shown). The spring 1513 is sleeved around the outer periphery of the roller main shaft 1512 and is located between the roller sleeve 1511 and the roller connecting shaft 1514. In actual use, the tape head of the adhesive tape 200 passes under the roller sleeve. By adjusting the position of the roller sleeve 1511 in the left and right directions, the position of the tape 200 in the left and right directions can be adjusted. For example, when the tape 200 needs to be moved to the right, the fastener can be removed from the limit piece 15111 first, and then the limit piece 15111 can be removed from the roller main shaft 1512. Then the roller sleeve 1511 and the roller bearing can be moved toward the direction close to the spring 1513, that is, moved to the right. At this time, the spring 1513 is compressed, and then the limit piece 15111 is installed on the roller main shaft 1512. Then the fastener is installed in the mounting hole and the end of the fastener is abutted against the outer periphery of the roller main shaft 1512. In this way, the tape 200 can be moved to the right.

[0046] The number of mounting holes and fasteners can be set according to actual conditions.

[0047] The sensor assembly is used to detect the presence of tape 200 on the material tray assembly 12. The sensor assembly includes a sensor mounting plate 161, two sensor mounting blocks 162, and a set of through-beam photoelectric sensors. The sensor mounting plate 161 is positioned on the outer side of the transverse portion of the unloading rubber tray base plate 11 (i.e., the side of the transverse portion away from the center of the mounting platform 1). The two sensor mounting blocks 162 are positioned on the side of the sensor mounting plate 161 away from the unloading rubber tray base plate 11. The material tray 122 is positioned between the two sensor mounting blocks 162. The through-beam photoelectric sensors include a light emitting sensor 163a and a light receiving sensor 163b. These sensors are positioned at the tops of the two sensor mounting blocks 162, facing each other front to back. The wiring connecting the light emitting sensor 163a and the light receiving sensor 163b passes through the mounting slot of the material tray 122. Light-emitting sensor 163a is configured to emit infrared light toward light-receiving sensor 163b, and light-receiving sensor 163b is configured to receive the infrared light emitted by light-emitting sensor 163a. In actual use, when light-emitting sensor 163a emits infrared light toward light-receiving sensor 163b, if light-receiving sensor 163b fails to receive the infrared light emitted by light-emitting sensor 163a, it indicates that adhesive tape 200 is present on tray 122. If light-receiving sensor 163b receives the infrared light emitted by light-emitting sensor 163a, it indicates that adhesive tape 200 is not present on tray 122. At this point, the control system can issue an alarm, light, or other reminder to the operator.

[0048] Combine Figure 6 As shown, the laminating module 30 is used to clamp the tape head of the tape 200. The laminating module 30 is arranged on the front of the mounting platform 1 and is located in front of the unloading rubber disc module 10. The laminating module 30 includes a laminating claw cylinder 31, a laminating soft claw 32a and a laminating hard claw 32b. The two laminating claw cylinders 31 of the two glue preparation and laminating modules are both arranged on the side of the laminating mounting plate close to the unloading rubber disc module 10. The laminating mounting plate is arranged on the front of the mounting platform 1. The laminating soft claw 32a and the laminating hard claw 32b are arranged opposite to each other on the left and right and are both arranged at the top of the laminating claw cylinder 31. The laminating claw cylinder 31 is used to drive the laminating soft claw 32a and the laminating hard claw 32b to open or close to loosen the tape head or clamp the tape head.

[0049] The material of the soft clamping jaw 32a is, for example, silicone, rubber, etc., and the material of the hard clamping jaw 32b is, for example, stainless steel, etc. A plurality of protrusions 321 are provided on the side of the hard clamping jaw 32b close to the soft clamping jaw 32a. In actual use, the adhesive surface of the tape 200 is close to the hard clamping jaw 32b, and the non-adhesive surface of the tape 200 is close to the soft clamping jaw 32a. The plurality of protrusions 321 can play an anti-sticking role, thereby preventing the hard clamping jaw 32b and the tape head from sticking together. The number of protrusions 321 can be set according to actual conditions. Furthermore, the side of the hard clamping jaw 32b close to the soft clamping jaw 32a is an anti-sticking treatment surface, such as an EPC treatment surface, which can further play an anti-sticking role.

[0050] The front of the mounting platform 1 is provided with a plurality of guide rollers 20 between the unloading rubber disc module 10 and the laminating module 30, for example, four guide rollers 20. Figure 1 and Figure 3 As shown, the tape 200 passing under the roller sleeve 1511 of the spring roller 151 first passes over the four guide rollers 20. After being guided by the four guide rollers 20, it enters between the soft and hard clamping jaws 32a and 32b. The clamping jaw cylinder 31 drives the soft and hard clamping jaws 32a and 32b to close, thereby clamping the tape head. After the soft and hard clamping jaws 32a and 32b clamp the tape head, the tape head is located in front of the soft and hard clamping jaws 32a and 32b, making it easier for the glue pulling module 40 to clamp the tape head.

[0051] The structure of the guide roller 20 is the same as that of the spring roller 151, and will not be repeated here.

[0052] Combine Figure 7 and Figure 8 As shown, the glue pulling module 40 is located in front of the glue clamping module 30 and is used to clamp the tape head on the glue clamping module 30 and drive the tape head forward to pull the tape 200 to a predetermined length. The glue pulling module 40 includes a glue pulling mounting seat 41, a glue pulling claw cylinder 42 arranged at the top of the glue pulling mounting seat 41, a glue pulling soft claw 43a and a glue pulling hard claw 43b. The glue pulling mounting seat 41 is arranged on the front of the mounting platform 1 through a glue pulling slide rail assembly, and the glue pulling mounting seat 41 can move back and forth relative to the mounting platform 1. The glue pulling soft claw 43a and the glue pulling hard claw 43b are arranged opposite to each other on the left and right and are both arranged at the end of the glue pulling claw cylinder 42 close to the glue clamping module 30. The glue pulling soft claw 43a corresponds to the glue clamping soft claw 32a, and the glue pulling hard claw 43b corresponds to the glue clamping hard claw 32b. The adhesive clamping cylinder 42 is used to drive the adhesive soft clamping jaw 43a and the adhesive hard clamping jaw 43b to open or close. The forward and backward movement of the adhesive mounting base 41 can drive the adhesive clamping cylinder 42, the adhesive soft clamping jaw 43a and the adhesive hard clamping jaw 43b to move forward and backward.

[0053] The adhesive slide rail assembly includes an adhesive slide rail 412 and an adhesive slider 413, which are positioned on the front of the mounting platform 1. The length of the adhesive slide rail 412 is aligned with the length of the mounting platform 1. The adhesive slider 413 slidably engages with the adhesive slide rail 412, allowing it to slide back and forth along the adhesive slide rail 412. The adhesive slider 413 is positioned at the bottom end of the adhesive mounting base 41. The provision of the adhesive slide rail assembly improves the smoothness of the back and forth movement of the adhesive mounting base 41.

[0054] The soft adhesive clamping jaw 43a is made of, for example, silicone or rubber, while the hard adhesive clamping jaw 43b is made of, for example, stainless steel. Several teeth 431 are provided on the side of the hard adhesive clamping jaw 43b proximal to the soft adhesive clamping jaw 43a. In actual use, the adhesive surface of the tape 200 is adjacent to the hard adhesive clamping jaw 43b, while the non-adhesive surface of the tape 200 faces the soft adhesive clamping jaw 43a. The provision of these teeth 431 provides an anti-adhesion function, preventing the hard adhesive clamping jaw 43b and the tape 200 from adhering to each other. The number of teeth 431 can be adjusted based on actual conditions. Furthermore, the side of the hard adhesive clamping jaw 43b proximal to the soft adhesive clamping jaw 43a is treated with an anti-adhesion treatment, such as an EPC treatment, to further enhance the anti-adhesion function.

[0055] The glue-pulling drive module 90 is used to drive the glue-pulling mounting bases 41 of the two glue-pulling modules 40 to move forward and backward. Specifically, the glue-pulling drive module 90 includes a glue-pulling drive motor 91, a glue-pulling screw 92, and a glue-pulling nut 94. The glue-pulling drive motor 91 is disposed on the back of the mounting platform 1. The two ends of the glue-pulling screw 92 are rotatably disposed on the back of the mounting platform 1 via two bearing seats 921. The length direction of the glue-pulling screw 92 is the same as the length direction of the mounting platform 1. One end of the glue-pulling screw 92 is connected to the output end of the glue-pulling drive motor 91 via a coupling 93. The glue-pulling screw 92 is located below the two glue-pulling modules 40. The glue-pulling nut 94 is threadedly engaged with the glue-pulling screw 92. The glue-pulling nut 94 is disposed on the top of a glue-pulling mounting plate 941. The two ends of the glue-pulling mounting plate 941 are connected to the glue-pulling mounting bases 41 of the two glue-pulling modules 40 via two glue-pulling connecting plates 411. The two rubber connecting plates 411 respectively pass through the two through slots 1a of the installation platform 1 (see Figure 1 and Figure 3The glue pulling drive motor 91 is used to drive the glue pulling screw 92 to rotate, thereby driving the glue pulling nut 94 to move forward and backward, thereby driving the glue pulling mounting base 41 of the two glue pulling modules 40 to move forward and backward through the two glue pulling connecting plates 411, and further driving the corresponding glue pulling claw cylinder 42, glue pulling soft claw 43a and glue pulling hard claw 43b to move forward and backward. In actual application, after the tape head is clamped by the soft clamping jaw 32a and the hard clamping jaw 32b, the rubber pulling drive motor 91 drives the rubber pulling screw 92 to rotate, thereby driving the rubber pulling nut 94 to move backward, and then driving the rubber pulling mounting seat 41, the rubber pulling jaw cylinder 42, the soft rubber pulling jaw 43a and the hard rubber pulling jaw 43b to move backward until the part of the tape head located in front of the soft rubber clamping jaw 32a and the hard rubber clamping jaw 32b is located between the soft rubber pulling jaw 43a and the hard rubber pulling jaw 43b. At this time, the soft rubber pulling jaw 43 is driven by the rubber pulling jaw cylinder 42. a and the glue-pulling hard clamping jaw 43b are closed to clamp the tape head, and at the same time, the glue-pulling clamping jaw cylinder 31 drives the glue-pulling soft clamping jaw 32a and the glue-pulling hard clamping jaw 32b to open to release the tape head, and then the glue-pulling drive motor 91 drives the glue-pulling screw rod 92 to rotate, thereby driving the glue-pulling nut 94 to move forward, and then driving the glue-pulling mounting seat 41, the glue-pulling clamping jaw cylinder 42, the glue-pulling soft clamping jaw 43a, the glue-pulling hard clamping jaw 43b and the tape head clamped by the glue-pulling soft clamping jaw 43a and the glue-pulling hard clamping jaw 43b to move forward, so that the tape 200 can be pulled out to a predetermined length. The two glue-pulling modules 40 of the present invention share one glue-pulling drive module 90, which can save costs and reduce the overall volume of the mechanism, thereby reducing the overall size of the winding machine.

[0056] Combine Figure 9 As described, the tape cutting module 50 is located on one side of the adhesive drawing module 40, and the adhesive disc unloading module 10 is located behind the tape cutting module 50. The tape cutting module 50 is used to cut the adhesive tape 200 drawn by the adhesive drawing module 40. In this embodiment, the two adhesive drawing modules 40 are located between the two tape cutting modules 50.

[0057] The tape cutting module 50 includes a cutting mounting base 51, a cutting drive 52, and a cutter 54. The cutting drive 52 is a pneumatic cylinder and is disposed on the side of the cutting mounting base 51 close to the adhesive transfer and tapping module 70, that is, on the side of the cutting mounting base 51 away from the adhesive tray module 10. The cutter 54 is disposed on the end of the cutting drive 52 close to the adhesive drawing module 40 via a cutter seat 53. The cutting drive 52 is used to drive the cutter 54 to move toward or away from the adhesive drawing module 40. In actual application, after the adhesive drawing module 40 has drawn the tape 200 to a predetermined length, the cutting drive 52 drives the cutter 54 to move toward the adhesive drawing module 40, so that the drawn tape 200 can be cut by the cutter 54.

[0058] The support module 60 is used to provide support for the pulled-out adhesive tape 200. The support module 60 includes a support block 61 and a support driver 62. The support block 61 is located between the laminating module 30 and the glue pulling module 40, and the support block 61 is close to the laminating module 30. The cutter 54 is opposite to the end of the support block 61 close to the laminating module 30. A plurality of teeth 611 are provided on the side of the support block 61 close to the cutter 54. The support driver 62 is a cylinder, and the support driver 62 is arranged on the front of the mounting platform 1 through a cylinder seat. The support driver 62 is located below the cutting driver 52. The output end of the support driver 62 is located between the laminating module 30 and the glue pulling module 40 and is provided with the support block 61. The support driver 62 is used to drive the support block 61 to move toward or away from the cutter 54. In actual use, after the adhesive tape 200 is pulled out by the adhesive drawing module 40, the adhesive surface of the adhesive tape 200 contacts the teeth 611 of the support block 61. The support block 61 thus provides support for the adhesive tape 200, facilitating the severing of the pulled adhesive tape 200 by the cutter 54. The teeth 611 prevent the adhesive tape 200 from adhering to the support block 61. The support drive 62 drives the support block 61 toward or away from the cutter 54, allowing the position of the support block 61 to be adjusted in the left-right direction, thereby accommodating adhesive tapes 200 of varying thicknesses.

[0059] Combine Figure 10 and Figure 11 As shown, the glue transferring and slapping module 70 is used to absorb the adhesive tape 200 before the adhesive tape cutting module 50 cuts the pulled adhesive tape 200, and is used to apply the adhesive tape 200 after the adhesive tape cutting module 50 cuts the pulled adhesive tape 200. The glue transferring and slapping module 70 is located on one side of the adhesive pulling module 40 and in front of the adhesive tape cutting module 50. The glue transferring and slapping module 70 includes a glue transferring and slapping mounting seat 71, a glue transferring and slapping mounting plate 72, a short glue slapping block 74, a long glue slapping block 76, a first glue transferring and slapping driving member 73, and a second glue transferring and slapping driving member 75.

[0060] The glue transfer and rubber mounting plate 72 is slidably arranged on the side of the glue transfer and rubber mounting seat 71 close to the tape cutting module 50 through the glue transfer and rubber sliding rail assembly. Specifically, the glue transfer and rubber sliding rail assembly includes a glue transfer and rubber sliding rail 712 and a glue transfer and rubber sliding block 713. The glue transfer and rubber sliding rail 712 is arranged on the side of the glue transfer and rubber mounting seat 71 close to the tape cutting module 50. The glue transfer and rubber sliding block 713 slides with the glue transfer and rubber sliding rail 712, and the glue transfer and rubber sliding block 713 can slide along the glue transfer and rubber sliding rail 712 in the direction close to or away from the glue pulling module 40. The glue transfer and rubber sliding block 713 is arranged on the side of the glue transfer and rubber mounting plate 72 close to the glue transfer and rubber mounting seat 71.

[0061] The long adhesive sucking and slapping block 76 is located in front of the short adhesive sucking and slapping block 74, and the two are arranged side by side. The adhesive transfer and slapping mounting plate 72 is L-shaped. The end of the adhesive transfer and slapping mounting plate 72 near the adhesive drawing module 40 is provided with an adhesive transfer and slapping support plate 721. The long adhesive sucking and slapping block 76 is located at the end of the adhesive transfer and slapping support plate 721 near the adhesive drawing module 40. The end of the short adhesive sucking and slapping block 74 near the adhesive drawing module 40 is provided with a plurality of evenly distributed first suction holes 741 for sucking the pulled adhesive tape 200. The end of the long adhesive sucking and slapping block 76 near the adhesive drawing module 40 is provided with a plurality of evenly distributed second suction holes 761 for sucking the pulled adhesive tape 200. The number of first suction holes 741 and second suction holes 761 can be set according to actual conditions. The top of the short-suction glue-slapping block 74 is provided with a first connector 742. A first air channel is provided inside the short-suction glue-slapping block 742. The first air channel connects the plurality of first suction holes 741 to the first connector 742. The first connector 742 is used to connect to a first vacuum device. The top of the long-suction glue-slapping block 76 is provided with a second connector 762. A second air channel is provided inside the long-suction glue-slapping block 76. The second air channel connects the plurality of second suction holes 761 to the second connector 762. The second connector 762 is used to connect to a second vacuum device. In actual use, the first vacuum device evacuates the first air channel through the first connector 742, thereby evacuating the plurality of first suction holes 741. In this way, the pulled-out adhesive tape 200 can be adsorbed through the plurality of first suction holes 741. The first vacuum device stops evacuating the first air channel through the first connector 742, thereby stopping evacuating the plurality of first suction holes 741. In this way, the adhesive tape can be released through the plurality of first suction holes 741. The second vacuum device vacuums the second air channel through the second connector 762, thereby vacuuming the plurality of second adsorption holes 761, so that the pulled-out tape 200 can be adsorbed through the plurality of second adsorption holes 761. The second vacuum stops vacuuming the second air channel through the second connector 762, thereby stopping vacuuming the plurality of second adsorption holes 761, so that the tape 200 can be released through the plurality of second adsorption holes 761.

[0062] The first adhesive transfer driver 73 is a pneumatic cylinder. The short adhesive suction block 74 is disposed at one end of the first adhesive transfer driver 73 near the adhesive drawing module 40. The first adhesive transfer driver 73 is used to drive the short adhesive suction block 74 to move toward or away from the adhesive drawing module 40 to move closer to or away from the drawn adhesive tape 200. The second adhesive transfer driver 75 includes an adhesive transfer motor 751, an adhesive transfer screw 753, and an adhesive transfer nut 755. The adhesive transfer motor 751 is disposed on a side of the adhesive transfer mounting base 71 away from the adhesive tape cutting module 50. One end of the adhesive transfer screw 753 is connected to the output end of the adhesive transfer motor 751, and the other end is adjacent to the adhesive drawing module 40 and located above the long adhesive suction block 76. The adhesive transfer nut 755 is threadedly engaged with the adhesive transfer screw 753. The adhesive transfer nut 755 is connected to the adhesive transfer mounting plate 72 via the adhesive transfer connector 754. The adhesive transfer connector 754 is located between the adhesive transfer mounting base 71 and the adhesive drawing module 40. The adhesive transfer motor 751 is used to drive the adhesive transfer screw 753 to rotate, thereby driving the adhesive transfer nut 755 to move toward or away from the adhesive drawing module 40, thereby driving the adhesive transfer mounting plate 72 to move toward or away from the adhesive drawing module 40, and further driving the adhesive transfer support plate 721, the first adhesive transfer driver 73, and the long adhesive suction block 76 to move toward or away from the adhesive drawing module 40 to move closer to or away from the drawn adhesive tape 200. When the first adhesive transfer driver 73 moves toward or away from the adhesive drawing module 40, it can drive the short adhesive suction block 74 to move synchronously.

[0063] One end of the glue transfer and patting glue support plate 721 near the glue pulling module 40 is provided with an L-shaped glue suction and patting glue pad 77, which is located in front of the long glue suction and patting glue block 76 and the two are arranged side by side. The glue suction and patting glue pad 77 can move synchronously with the glue transfer and patting glue support plate 721. In actual application, after the adhesive tape 200 is pulled out by the long glue suction and patting glue block 76 and the short glue suction and patting glue block 74, the adhesive tape head clamped by the soft glue pulling jaw 32a and the hard glue pulling jaw 32b will contact the glue suction and patting glue pad 77. When the adhesive tape is applied, the short glue suction and patting glue block 74 can be used to fit the adhesive tape head to the position where the adhesive tape 200 needs to be applied, thereby avoiding the situation where the adhesive tape head does not fit to the position where the adhesive tape 200 needs to be applied.

[0064] A protective cover 752 is provided at one end of the glue transferring and slapping motor 751 close to the glue pulling module 40, the glue transferring and slapping screw rod 753 is located in the protective cover 752, and the glue transferring and slapping nut 755 is partially located in the protective cover 752. The protective cover 752 protects the glue transferring and slapping screw rod 753.

[0065] The shuttle glue transfer module 80 includes a shuttle glue transfer linear module 81. Two support plates 3 are respectively provided on the back and front sides of the large plate 2. The shuttle glue transfer linear module 81 is arranged at the top of the two support plates 3 and passes through the through hole 2a of the large plate 2. The glue transfer and rubber mounting seat 71 is arranged at the top of the shuttle glue transfer linear module 81. The shuttle glue transfer linear module 81 is used to drive the glue transfer and rubber mounting seat 71 to move back and forth, thereby driving the glue transfer and rubber mounting plate 72, the glue transfer and rubber supporting plate 721, the first glue transfer and rubber driving member 73, the second glue transfer and rubber driving member 75, the short glue transfer and rubber block 74, the long glue transfer and rubber block 76, the glue suction and rubber pad 77, etc. to move back and forth.

[0066] Through the above structure, the present invention can implement the application of adhesive tape 200 on both sides of the joint position of the new and old pole pieces, on both sides of the pole piece cutting position, on both sides of the pole piece corner position, and on both sides of the pole piece's ear. Since the length of the adhesive tape 200 applied on both sides of the pole piece's ear is shorter than the length of the adhesive tape 200 applied on both sides of the joint position of the new and old pole pieces, on both sides of the pole piece cutting position, and on both sides of the pole piece corner position, a short adhesive suction and patting block 74 is used to absorb the adhesive tape 200 and apply the adhesive tape 200. The lengths of the adhesive tape 200 applied on both sides of the joint position of the new and old pole pieces, on both sides of the pole piece cutting position, and on both sides of the pole piece corner position are the same. The long adhesive suction and patting block 76 and the short adhesive suction and patting block 74 are used to jointly absorb the adhesive tape 200 and apply the adhesive tape 200. The working principle of the present invention is as follows:

[0067] Apply tape 200 to both sides of the pole piece's tabs, taking the adhesive preparation and adhesive application module on the left as an example:

[0068] S1. First install the tape 200 on the material tray 122, then pass the tape head of the tape 200 from under the supporting roller 17, over the first cache roller 132, under the third cache roller 136, in front of the second cache roller 133, then pass from behind the clamping roller 141, and then pass from under the spring roller 151 to change the running direction of the tape 200 from vertical to horizontal, and then pass through the four guide rollers 20 and enter between the soft clamping jaw 32a and the hard clamping jaw 32b so that the tape head part is located in front of the soft clamping jaw 32a and the hard clamping jaw 32b.

[0069] S2. Then, the clamping jaw cylinder 31 drives the soft clamping jaw 32a and the hard clamping jaw 32b to close to clamp the tape head.

[0070] S3. Then, the third buffer roller 136 is driven downward by the buffer driving member 131 to buffer the adhesive tape 200 to a predetermined length, which is the same as the length of the adhesive tape 200 required by the tab.

[0071] S4. Then, the glue pulling module 40 is driven to move backward by the glue pulling driving module 90 until the portion of the tape head located in front of the soft glue clamping jaw 32a and the hard glue clamping jaw 32b is located between the soft glue pulling jaw 43a and the hard glue pulling jaw 43b.

[0072] S5. Then, the adhesive pulling jaw cylinder 42 drives the adhesive pulling soft jaw 43a and the adhesive pulling hard jaw 43b to close to clamp the tape head.

[0073] S6. Then, the soft clamping jaw 32a and the hard clamping jaw 32b are driven to open by the clamping jaw cylinder 31 to release the tape head. At the same time, the third cache roller 136 is driven to move upward by the cache drive member 131, and the glue pulling module 40 is driven to move forward to a predetermined position by the glue pulling drive module 90, thereby driving the tape head to move forward. In this way, the glue pulling module 40 will pull the tape 200 to a predetermined length. At this time, the tape 200 contacts the several teeth 611 of the support block 61, so that the support block 61 can support the tape 200.

[0074] S7, then the shuttle glue transfer linear module 81 drives the glue transfer and patting glue module 70 to move backward to the glue preparation station, such as Figure 1 and Figure 3 Position shown.

[0075] S8. Then, the first glue moving and smacking driving member 73 drives the short glue sucking and smacking block 74 to move toward the glue pulling module 40 until the end of the short glue sucking and smacking block 74 close to the glue pulling module 40 contacts the pulled adhesive tape 200.

[0076] S9 , the plurality of first adsorption holes 741 are then vacuumed by a first vacuum device, so that the plurality of first adsorption holes 741 can adsorb the pulled-out adhesive tape 200 .

[0077] S10, then the cutter 54 is driven by the cutting drive member 52 to move toward the glue drawing module 40 until the cutter 54 abuts against the support block 61, so that the pulled tape 200 can be cut by the cutter 54, wherein the tape 200 located between the cutter 54 and the glue drawing module 40 is the cut tape 200, the tape head clamped by the soft glue drawing jaw 43a and the hard glue drawing jaw 43b is the old tape head, and the part of the tape located between the soft glue clamping jaw 32a and the hard glue clamping jaw 32b is the new tape head.

[0078] S11. Then, the pressing block 143 is driven by the pressing driving member 142 to move toward the pressing roller 141 to press the tape 200. At the same time, the soft clamping jaw 32a and the hard clamping jaw 32b are driven to close by the clamping jaw cylinder 31 to clamp the new tape head, and the soft clamping jaw 43a and the hard clamping jaw 43b are driven to open by the pulling jaw cylinder 42 to release the old tape head.

[0079] S12, then the short glue sucking and slapping block 74 is driven back to the initial position by the first glue moving and slapping driving member 73, and at this time the cut adhesive tape 200 is adsorbed on the short glue sucking and slapping block 74.

[0080] S13, then the glue transfer and glue tapping module 70 is driven by the shuttle glue transfer linear module 81 to move forward to the glue sticking station of the pole ear of the pole piece.

[0081] S14. Then, the first glue moving and patting driving component 73 drives the short glue sucking and patting block 74 to move toward the direction close to the tab, so that the cut tape 200 is attached to one side of the tab through the short glue sucking and patting block 74, and then the first vacuum equipment stops vacuuming the first adsorption holes 741. In this way, the cut tape 200 is attached to one side of the tab.

[0082] S15. After completion, the first glue transfer and glue patting driving component 73 drives the short glue suction and glue patting block 74 to move away from the tab to return to the initial position, and then the shuttle glue transfer linear module 81 drives the glue transfer and glue patting module 70 to move backward to the glue preparation station.

[0083] The gluing action of the glue preparation and gluing module on the right is consistent with that of the glue preparation and gluing module on the left and is carried out simultaneously. Since the glue preparation and gluing module on the right and the glue preparation and gluing module on the left are symmetrically distributed on the left and right, the glue preparation and gluing module on the right and the glue preparation and gluing module on the left can be used to apply tape to both sides of the pole piece's ear.

[0084] Afterwards, if you want to apply tape to both sides of the cutting position of the electrode, still take the glue preparation and application module located on the left as an example, and repeat the actions of steps S3-S15. Among them, in step S3, the length of the cached tape 200 is the same as the length of the tape 200 required for the cutting position of the electrode. In step S8, the second glue transfer and patting driving member 75 drives the glue transfer and patting mounting plate 72 to move toward the direction close to the glue pulling module 40, thereby driving the short glue suction and patting block 74, the long glue suction and patting block 76 and the glue suction and patting pad block 77 to move toward the direction close to the glue pulling module 40, until the end of the short glue suction and patting block 74, the long glue suction and patting block 76 and the glue suction and patting pad block 77 close to the glue pulling module 40 contacts the pulled tape 200. In step S9, the first vacuum equipment and the second vacuum equipment are used to simultaneously evacuate the plurality of first adsorption holes 741 and the plurality of second adsorption holes 761, so that the adhesive tape 200 pulled out can be adsorbed by the plurality of first adsorption holes 741 and the plurality of second adsorption holes 761. In step S12, the second adhesive transfer and patting adhesive driving member 75 drives the adhesive transfer and patting adhesive mounting plate 72 to move in a direction away from the adhesive pulling module 40, thereby driving the short adhesive suction and patting adhesive block 74, the long adhesive suction and patting adhesive block 76 and the adhesive suction and patting adhesive pad 77 to return to the initial position. At this time, the cut adhesive tape 200 is adsorbed on the short adhesive suction and patting adhesive block 74 and the long adhesive suction and patting adhesive block 76, and the old adhesive tape head of the cut adhesive tape 200 is in contact with the adhesive suction and patting adhesive pad 77. In step S13, the adhesive transfer and patting adhesive module 70 is driven by the shuttle adhesive transfer linear module 81 to move forward to the glue sticking station at the cutting position of the electrode. In step S14, the second glue transfer and patting glue driving component 75 drives the glue transfer and patting glue mounting plate 72 to move toward the cutting position close to the pole piece, thereby driving the short glue suction and patting glue block 74, the long glue suction and patting glue block 76 and the glue suction and patting glue pad block 77 to move toward the cutting position close to the pole piece, so that the short glue suction and patting glue block 74, the long glue suction and patting glue block 76 and the glue suction and patting glue pad block 77 can jointly stick the cut tape 200 to one side of the cutting position of the pole piece, and then stop vacuuming the several first adsorption holes 741 and the several second adsorption holes 761 through the first vacuum equipment and the second vacuum equipment, so that the cut tape 200 is stuck on one side of the cutting position of the pole piece. In step S15, the second glue transfer and patting glue driving component 75 drives the glue transfer and patting glue mounting plate 72 to move in the direction away from the cutting position of the pole piece, thereby driving the short glue suction and patting glue block 74, the long glue suction and patting glue block 76 and the glue suction and patting glue pad block 77 to move in the direction away from the cutting position of the pole piece to return to the initial position, and then drives the glue transfer and patting glue module 70 to move backward to the glue preparation station through the shuttle glue transfer linear module 81.The gluing action of the glue preparation and gluing module on the right is consistent with that of the glue preparation and gluing module on the left and is carried out simultaneously. Since the glue preparation and gluing module on the right and the glue preparation and gluing module on the left are symmetrically distributed on the left and right, the glue preparation and gluing module on the right and the glue preparation and gluing module on the left can be used to stick tape on both sides of the cutting position of the electrode.

[0085] The action of applying tape to both sides of the connection position of the new and old electrodes and both sides of the corner position of the electrode is the same as the action of applying tape to both sides of the cutting position of the electrode, with the only difference being step S13, step S14 and step S15.

[0086] Specifically, tape is applied to both sides of the joint position of the new and old pole pieces. In step S13, the glue transfer and patting glue module 70 is driven by the shuttle glue transfer linear module 81 to move forward to the glue application station of the joint position of the new and old pole pieces. In step S14, the glue transfer and patting glue mounting plate 72 is driven by the second glue transfer and patting glue driving member 75 to move toward the direction of the joint position of the new and old pole pieces, thereby driving the short glue suction and patting glue block 74, the long glue suction and patting glue block 76 and the glue suction and patting glue pad block 77 to move toward the direction of the joint position of the new and old pole pieces, thereby The adhesive block 74, the long adhesive sucking and patting adhesive block 76 and the adhesive sucking and patting adhesive pad 77 can attach the cut adhesive tape 200 to one side of the joint position of the new and old electrodes, and then stop vacuuming the first adsorption holes 741 and the second adsorption holes 761 through the first vacuum equipment and the second vacuum equipment. In this way, the cut adhesive tape 200 is attached to one side of the joint position of the new and old electrodes. In step S15, the second adhesive transfer and patting adhesive driving member 75 drives the adhesive transfer and patting adhesive mounting plate 72 to move away from the joint position of the new and old electrodes to return to the initial position.
