Description

Technical Field

[0001] This utility model relates to the field of coating equipment technology, specifically to a multi-width arc-shaped adhesive applicator. Background Technology

[0002] In the lithium battery coating process, empty rolls are a crucial material, serving the function of winding foil and electrode sheets. Before the coating equipment automatically changes the roll, manual labor is required to apply double-sided adhesive along the axial direction of the empty roll on its outer circumference to ensure successful bonding of the foil or electrode sheet to the empty roll. However, manual adhesive application suffers from several problems, including slow speed and difficulty in ensuring the straightness of the double-sided adhesive tape, thus reducing production efficiency. While existing automatic adhesive application equipment can replace manual labor, it is only suitable for one type of wide double-sided adhesive, limiting its applicability. Utility Model Content

[0027] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0028] Please refer to Figures 1 to 5This utility model provides a multi-width curved surface adhesive application mechanism, including a support frame 10 and an adhesive application component 20 and a pressing component 30 located below the support frame 10. The pressing component 30 and the adhesive application component 20 are arranged side by side along the length of the support frame 10.

[0029] The support frame 10 has a through hole 11 in the middle for the release paper 101 of the double-sided adhesive 100 to pass through. The support frame 10 has a mounting plate 12 on one side of the top end. The mounting plate 12 is used to install on the power mechanism. In actual application, the power mechanism can drive the support frame 10 to move up and down and to move horizontally back and forth along the axis of the empty drum via the mounting plate 12.

[0030] The adhesive application assembly 20 includes an adhesive application support 21, an adhesive application roller 22, and a guide roller 23. The adhesive application support 21 is U-shaped with its opening facing downwards. The adhesive application support 21 is connected to the support frame 10. Both the adhesive application roller 22 and the guide roller 23 are mounted on the adhesive application support 21. The guide roller 23 is located on the side of the adhesive application roller 22 away from the adhesive application assembly 30, and the guide roller 23 and the adhesive application roller 22 are staggered vertically. The adhesive application roller 22 is used to adhere the double-sided adhesive 100 to the outer circumferential surface of the empty roll. The guide roller 23 is used to support the double-sided adhesive 100. In practical applications, when the support frame 10 moves up and down, the support frame 10 can drive the adhesive application support 21, the adhesive application roller 22, and the guide roller 23 to move up and down. When the support frame 10 moves horizontally back and forth along the axial direction of the empty drum, the support frame 10 can drive the adhesive application support 21, the adhesive application roller 22, and the guide roller 23 to move horizontally back and forth along the axial direction of the empty drum.

The adhesive-applying fastener 213 can move up and down relative to the support frame 10. The head of the adhesive-applying fastener 213 forms an annular adhesive-applying limiting part 2131, which abuts against the top of the support frame 10 to limit the downward movement of the adhesive-applying fastener 213. The adhesive-applying fastener 213 is partially installed in the adhesive-applying mounting hole, and an adhesive-applying elastic element (not shown in the figure) is sleeved on the adhesive-applying fastener 213. One end of the adhesive-applying elastic element is close to the adhesive-applying floating block 212 and connected to the adhesive-applying fastener 213, and the other end of the adhesive-applying elastic element is connected to the bottom end of the support frame 10. The adhesive-applying fastener 213 is preferably a shouldered pin, and the adhesive-applying elastic element is preferably a spring. During the process of applying double-sided adhesive tape 100 to the outer circumferential surface of the empty roll using the applying roller 22, the adhesive roller 22 acts as a buffer and reset element when it comes into contact with the empty roll, allowing the applying roller 22 to move up and down and preventing damage to the empty roll. In this embodiment, there are two adhesive application through holes, two adhesive application mounting holes, two adhesive application fasteners 213, and two adhesive application elastic elements. It can be understood that the number of adhesive application through holes, adhesive application mounting holes, adhesive application fasteners 213, and adhesive application elastic elements can be set according to actual conditions.

[0032] The adhesive applicator 22 includes an adhesive applicator shaft 221 and an adhesive applicator sleeve 222 rotatably fitted onto the adhesive applicator shaft 221. Both ends of the adhesive applicator shaft 221 are respectively located on the inner walls of both ends of the adhesive applicator support 21. In this embodiment, the inner walls of both ends of the adhesive applicator support 21 are respectively provided with two first mounting holes, and both ends of the adhesive applicator shaft 221 are respectively located in the two first mounting holes. The adhesive applicator sleeve 222 partially protrudes from the bottom end of the adhesive applicator support 21.

[0033] In this embodiment, an adhesive application bearing 223 is provided inside the adhesive application roller sleeve 222. The adhesive application bearing 223 is sleeved on the adhesive application roller shaft 221 to provide rotational support for the adhesive application roller sleeve 222. There are two adhesive application bearings 223, which are respectively close to both ends of the adhesive application roller sleeve 222. It can be understood that the number of adhesive application bearings 223 can be set according to the actual situation.

[0034] The guide roller 23 includes a guide roller shaft 231 and a guide roller sleeve 232 rotatably fitted on the guide roller shaft 231. Both ends of the guide roller shaft 231 are respectively disposed on the inner walls of both ends of the adhesive application support 21. In this embodiment, the bottom end of the adhesive application support 21 has a notch 211, located on the side of the adhesive application roller 22 away from the adhesive pressing assembly 30. The inner walls of both ends of the adhesive application support 21 each have two second mounting holes, located above the notch 211. Both ends of the guide roller shaft 231 are respectively disposed in the two second mounting holes. The guide roller sleeve 232 partially protrudes from the bottom of the notch 211.

[0035] In this embodiment, a roller bearing 233 is provided inside the roller sleeve 232. The roller bearing 233 is sleeved on the roller shaft 231 to provide rotational support for the roller sleeve 232. There are two roller bearings 233, which are respectively close to both ends of the roller sleeve 232. Understandably, the number of roller bearings 233 can be set according to the actual situation.

[0036] The adhesive pressing assembly 30 includes an adhesive pressing support 31 and three adhesive pressing rollers. Understandably, the number of adhesive pressing rollers can also be other, such as four or five, depending on the actual situation. The adhesive pressing support 31 is U-shaped with its opening facing downwards. The adhesive pressing support 31 is connected to the support frame 10. The three adhesive pressing rollers are a curved intermediate roller 32, a curved middle pressure roller 33, and a curved outer roller 34. The curved intermediate roller 32, the curved middle pressure roller 33, and the curved outer roller 34 are arranged sequentially at intervals along the direction away from the adhesive application assembly 20 and are respectively mounted on the adhesive pressing support 31. The curved intermediate roller 32, the curved middle pressure roller 33, and the curved outer roller 34 are used to press the double-sided adhesive 100 tape onto the outer circumferential surface of the empty roll. In practical applications, when the support frame 10 moves up and down, it can drive the pressure support 31, the arc-shaped intermediate roller 32, the arc-shaped intermediate pressure roller 33, and the arc-shaped outer roller 34 to move up and down. When the support frame 10 moves horizontally back and forth along the axial direction of the empty drum, it can drive the pressure support 31, the arc-shaped intermediate roller 32, the arc-shaped intermediate pressure roller 33, and the arc-shaped outer roller 34 to move horizontally back and forth along the axial direction of the empty drum.

[0037] In this embodiment, the top of the pressure-adhesive support 31 is provided with a pressure-adhesive floating block 311, the support frame 10 is provided with a pressure-adhesive through hole, the pressure-adhesive floating block 311 is provided with a pressure-adhesive mounting hole, and a pressure-adhesive fastener 312 passes through the pressure-adhesive through hole. The pressure-adhesive fastener 312 can move up and down relative to the support frame 10. The head of the pressure-adhesive fastener 312 forms an annular pressure-adhesive limiting part 3121, which abuts against the top of the support frame 10 to limit the downward movement of the pressure-adhesive fastener 312. The pressure-adhesive fastener 312 is partially installed in the pressure-adhesive mounting hole, and a pressure-adhesive elastic element 313 is sleeved on the pressure-adhesive fastener 312. One end of the pressure-adhesive elastic element 313 is close to the pressure-adhesive floating block 311 and connected to the pressure-adhesive fastener 312, and the other end of the pressure-adhesive elastic element 313 is connected to the bottom end of the support frame 10. The pressure-adhesive fastener 313 is preferably a shouldered pin, and the pressure-adhesive elastic element 313 is preferably a spring. During the process of tightly pressing the double-sided adhesive tape onto the outer circumference of the empty roll using the curved intermediate roller 32, the curved intermediate pressure roller 33, and the curved outer roller 34, the pressure elastic element 313 acts as a buffer and reset mechanism when the curved intermediate roller 32, the curved intermediate pressure roller 33, and the curved outer roller 34 come into contact with the empty roll. This allows the curved intermediate roller 32, the curved intermediate pressure roller 33, and the curved outer roller 34 to move up and down, preventing damage to the empty roll. In this embodiment, there are two pressure through holes, two pressure mounting holes, two pressure fasteners 312, and two pressure elastic elements 313. It can be understood that the number of pressure through holes, pressure mounting holes, pressure fasteners 312, and pressure elastic elements 313 can be set according to actual conditions.

[0038] The arc-shaped intermediate roller 32 includes an intermediate roller shaft 321 and an intermediate roller sleeve 322 rotatably fitted onto the intermediate roller shaft 321. Both ends of the intermediate roller shaft 321 are respectively disposed on the inner walls of both ends of the pressure support 31. In this embodiment, two first holes are respectively provided on the inner walls of both ends of the pressure support 31, and the two ends of the intermediate roller shaft 321 are respectively disposed in the two first holes. The intermediate roller sleeve 322 partially protrudes from the bottom end of the pressure support 31. An intermediate rubber sleeve 323 is fitted onto the intermediate roller sleeve 322. The length of the intermediate rubber sleeve 323 is equal to the length of the intermediate roller sleeve 322. Along the direction from both ends to the middle of the intermediate roller sleeve 323, the diameter of the intermediate rubber sleeve 323 gradually decreases to form an arc-shaped surface adapted to the outer circumferential surface of the empty roll. In practical applications, the arc-shaped surface of the intermediate rubber sleeve 323 can fit well with the outer circumference of the empty roll, so as to tightly adhere the double-sided tape 100 to the outer circumference of the empty roll, thereby avoiding air bubbles between the tape and the empty roll and avoiding wrinkling due to uneven tape tension.

[0039] In this embodiment, an intermediate bearing 324 is provided inside the intermediate roller sleeve 322. The intermediate bearing 324 is sleeved on the intermediate roller shaft 321 to provide rotational support for the intermediate roller sleeve 322 and the intermediate rubber sleeve 323. There are two intermediate bearings 324, which are respectively close to both ends of the intermediate roller sleeve 322. It can be understood that the number of intermediate bearings 324 can be set according to the actual situation.

[0040] The arc-shaped intermediate pressure roller 33 includes an intermediate pressure roller shaft 331 and an intermediate pressure roller sleeve 332 rotatably fitted on the intermediate pressure roller shaft 331. Both ends of the intermediate pressure roller shaft 331 are respectively disposed on the inner walls of both ends of the pressure support 31. In this embodiment, the inner walls of both ends of the pressure support 31 are respectively provided with two second holes, and both ends of the intermediate pressure roller shaft 331 are respectively disposed in the two second holes. The intermediate pressure roller sleeve 332 partially protrudes from the bottom end of the pressure support 31. Two intermediate pressure rubber sleeves 333 are respectively fitted on both ends of the intermediate pressure roller sleeve 332. The length of the intermediate rubber sleeve 323 is equal to the distance between the two intermediate pressure rubber sleeves 333. The diameter of the intermediate pressure rubber sleeve 333 gradually decreases along the direction near the middle of the intermediate pressure roller sleeve 323 to form an arc-shaped surface adapted to the outer circumferential surface of the empty drum. In practical applications, the arc-shaped surfaces of the two medium-pressure rubber sleeves 333 can fit well with the outer circumference of the empty roll, so as to achieve a tight fit of the tape to the outer circumference of the empty roll, thereby avoiding air bubbles between the tape and the empty roll and avoiding wrinkling due to uneven tape tension.

[0041] In this embodiment, an intermediate pressure bearing 334 is provided inside the intermediate pressure roller sleeve 332. The intermediate pressure bearing 334 is sleeved on the intermediate pressure roller shaft 331 to provide rotational support for the intermediate pressure roller sleeve 332 and the two intermediate pressure rubber sleeves 333. There are two intermediate pressure bearings 334, which are respectively close to both ends of the intermediate pressure roller sleeve 332. It can be understood that the number of intermediate pressure bearings 334 can be set according to the actual situation.

[0042] The arc-shaped outer roller 34 includes an outer roller shaft 341 and an outer roller sleeve 342 rotatably fitted onto the outer roller shaft 341. The two ends of the outer roller shaft 341 are respectively disposed on the inner walls of the two ends of the pressure support 31. In this embodiment, the inner walls of the two ends of the pressure support 31 are respectively provided with two third holes, and the two ends of the outer roller shaft 341 are respectively disposed in the two third holes. The outer roller sleeve 342 partially protrudes from the bottom end of the pressure support 31. Two outer rubber sleeves 343 are respectively fitted onto the two ends of the outer roller sleeve 342. The distance between the two outer rubber sleeves 343 is equal to the distance between the far ends of the two intermediate pressure rubber sleeves 333. The diameter of the outer rubber sleeve 343 gradually decreases along the direction near the middle of the outer roller sleeve 342 to form an arc-shaped surface adapted to the outer circumferential surface of the empty roll. In practical applications, the arc-shaped surfaces of the two outer rubber sleeves 343 can fit well with the outer circumferential surface of the empty roll, so as to achieve a tight fit of the tape to the outer circumferential surface of the empty roll, thereby avoiding air bubbles between the tape and the empty roll and avoiding wrinkling due to uneven tape tension.

[0043] In this embodiment, an outer bearing 344 is provided inside the outer roller sleeve 342. The outer bearing 344 is sleeved on the outer roller shaft 341 to provide rotational support for the outer roller sleeve 342 and the two outer rubber sleeves 343. There are two outer bearings 344, which are respectively close to both ends of the outer roller sleeve 342. Understandably, the number of outer bearings 344 can be set according to the actual situation.

[0044] The middle rubber sleeve 323, the medium pressure rubber sleeve 333, and the outer rubber sleeve 343 are all flexible anti-stick rubber sleeves, which can prevent damage to the tape and empty roll, and can prevent them from sticking together with the tape.

[0045] With the above structure, in practical application, the empty roll is located below the arc-shaped adhesive applicator, and the adhesive applicator roller 22 corresponds to one end of the empty roll. For example, when the width of the double-sided adhesive 100 is equal to the distance between the ends of the two outer adhesive sleeves 343, the double-sided adhesive 100 is first unwound by the unwinding mechanism. The unwound double-sided adhesive 100 passes over the roller sleeve 232 of the roller 23 and the adhesive sleeve 222 of the adhesive applicator roller 22. The support frame 10, adhesive applicator assembly 20, and adhesive pressing assembly 30 are driven downward by the power mechanism, so that the double-sided adhesive 100 can be moved downward by the adhesive sleeve 222 to stick the head of the double-sided adhesive 100 to the outer circumferential surface of the empty roll. Then, the support frame 10, adhesive applicator assembly 20, and adhesive pressing assembly 30 are driven horizontally along the axial direction of the empty roll towards the other end of the empty roll by the power mechanism. The unwinding mechanism continues to unwind the double-sided tape 100 and the rewinding mechanism rewinds the release paper 101 of the double-sided tape 100. During the horizontal movement of the support frame 10, the adhesive application assembly 20, and the adhesive pressing assembly 30 along the axial direction of the empty roll towards the other end of the empty roll, the adhesive application roller 21 can adhere the tape of the double-sided tape 100 to the outer circumferential surface of the empty roll. The tape and the empty roll are in point-to-surface contact. At the same time, the arc-shaped middle roller 32 of the adhesive pressing assembly 30 can first press the middle part of the tape (i.e., the middle part of the tape in the width direction) onto the outer circumferential surface of the empty roll. Then, the arc-shaped middle pressure roller 33 of the adhesive pressing assembly 30 can press the portion between the middle part of the tape and the two sides of the tape (i.e., the two sides of the tape in the width direction) onto the outer circumferential surface of the empty roll respectively. Finally, the arc-shaped outer roller 34 of the adhesive pressing assembly 30 can press the two sides of the tape onto the outer circumferential surface of the empty roll respectively. When the tape is applied to the other end of the empty roll, the double-sided tape 100 is cut by the cutting mechanism. At the same time, the power mechanism continues to drive the support frame 10, the tape application assembly 20 and the tape pressing assembly 30 to move horizontally towards the other end of the empty roll until the outer curved roller 34 moves out of the empty roll. In this way, the double-sided tape 100 is adhered to the outer circumferential surface of the empty roll.

[0046] When the width of the double-sided tape 100 is small, for example, when the width of the double-sided tape 100 is equal to the length of the intermediate adhesive sleeve 323, during the process of applying the tape of the double-sided tape 100 to the outer circumferential surface of the empty roll, only the arc-shaped intermediate roller 32 of the pressing assembly 30 performs the pressing work. When the width of the double-sided tape 100 is equal to the distance between the ends of the two intermediate pressure sleeves 333 that are far apart, during the process of applying the tape of the double-sided tape to the outer circumferential surface of the empty roll, only the arc-shaped intermediate roller 32 and the arc-shaped intermediate pressure roller 33 of the pressing assembly 30 perform the pressing work.

[0047] The above only lists three widths of double-sided tape 100. It can be understood that the width of double-sided tape 100 can also be other widths. This utility model can adapt to double-sided tape 100 with a width less than or equal to the distance between the far ends of the two outer adhesive sleeves 343.

[0048] This invention, through the provision of a support frame 10, an adhesive application component 20, and a pressing component 30, enables automatic application of double-sided tape 100 to the outer circumferential surface of an empty roll. This improves the application speed and ensures the straightness of the double-sided tape 100, thereby increasing production efficiency. The pressing component 30 includes at least three pressing rollers, accommodating double-sided tape 100 of varying widths, thus offering a wide range of applications. The three pressing rollers are a curved middle roller 32, a curved middle pressure roller 33, and a curved outer roller 34. These rollers effectively cooperate with the outer circumferential surface of the empty roll, ensuring a tight fit between the double-sided tape 100 and the outer circumferential surface when pressing the tape. This prevents air bubbles between the tape and the roll and avoids wrinkling due to uneven tape tension, ensuring the quality of the application.
