Description

Technical Field

[0001] This invention belongs to the technical field of protective film application devices, and particularly relates to a protective film application device for power bank production. Background Technology

[0002] A power bank is a portable energy storage device that is widely used in the daily charging of electronic products such as mobile phones and tablets. The casing of a power bank is usually made of metal or plastic. Before the power bank leaves the factory, a protective film needs to be attached to the surface of the power bank to prevent scratches and wear during transportation and use, and to ensure the appearance quality of the product.

[0003] However, existing film application devices only have one application roller. When there are raised text markings or decorative patterns on the surface of the power bank, the single application roller cannot fully adapt to the surface undulations during the rolling process. As a result, air bubbles in the raised areas cannot be effectively expelled, the protective film is not firmly adhered, and wrinkles easily form at the edges, which seriously affects the film application quality and product appearance. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that the single bonding roller cannot fully adapt to surface undulations during the rolling process, resulting in air bubbles in the raised areas not being effectively discharged, the protective film not adhering firmly, and wrinkles easily forming at the edges, which seriously affects the quality of the film and the appearance of the product. Therefore, a protective film application device for power bank production is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a protective film applicator for power bank production, comprising a driving device, an installation box, and a clamping mechanism:

Both ends of one side of the lifting plate are connected to second rotating seats. Both sides of the bottom of the lifting plate are connected to first connecting seats. The movement of the second rotating seats drives the lifting plate to slide in the mounting box, thereby driving the two first connecting seats on the lifting plate to move.

The clamping mechanism includes two clamping plates and a second connecting seat. Each clamping plate has a second movable cavity on one side, and a fitting mechanism is disposed in the second movable cavity.

One end of each of the two first rotating rods is rotatably connected to one side of the first rotating seat at the corresponding position, and the other end of each first rotating rod is rotatably connected to one side of the second rotating seat at the corresponding position.

[0008] Preferably, the lifting mechanism further includes a control lever: One end of the control rod is connected to one end of the first linear module. The inner cavity of the mounting box has a rotating hole. The outer side of the control rod is rotatably connected to the rotating hole in the inner cavity of the mounting box. The other end of the control rod has a control groove.

[0009] Preferably, the lifting mechanism further includes a telescopic rod: Multiple telescopic rods are connected at one end to a corresponding position on one side of the lifting plate, and at the other end to a corresponding position inside the mounting box. A return spring is sleeved on the outside of each telescopic rod, with one end of the return spring connected to a corresponding position on one side of the lifting plate and the other end connected to a corresponding position inside the mounting box.

[0010] Preferably, the clamping mechanism includes a second linear module, a second connecting plate, and a second rotating rod. The second linear module is connected to the first movable cavity at the corresponding position on one side. The second linear module is equipped with a second movable seat at both ends on one side, and a first connecting plate is connected to one side of the second movable seat. Two second connecting plates are connected at one end to one side of the first connecting plate at the corresponding position, and a clamping plate is connected to one side of the second connecting plate; One end of the second rotating rod is rotatably connected to the inner side of the first connecting seat. A through hole is provided on one side of the inner cavity of the first movable cavity. The other end of the second rotating rod extends into the first movable cavity through the through hole provided in the inner cavity of the first movable cavity at the corresponding position. One end of the second rotating rod is rotatably connected to the corresponding position in the inner cavity of the first movable cavity. A through hole is provided on one side of the second connecting seat. The outer side of the second rotating rod is connected to the through hole provided in the second connecting seat.

[0011] Preferably, the clamping mechanism further includes a drive rod: One end of the drive rod is connected to one end of the second linear module. The inner cavity of the first movable cavity has a rotating hole. The outer side of the drive rod is rotatably connected to the rotating hole in the inner cavity of the first movable cavity at the corresponding position. The other end of the drive rod has a drive groove.

[0012] Preferably, the clamping mechanism further includes a first limiting block: Two first limiting blocks are connected at one end to one side of the second movable seat at the corresponding position. The first movable cavity has first limiting grooves at both ends on one side of the cavity. The outer side of the first limiting block is slidably connected to the first limiting groove at the corresponding position.

[0013] Preferably, a first fitting wheel is connected to one side of the second connecting seat, and a second fitting wheel is connected to the bottom of the mounting box.

[0014] Preferably, the bonding mechanism includes a bonding block: The second movable cavity has multiple through slots, and multiple bonding blocks are slidably connected to the through slots in the second movable cavity at corresponding positions. One side of each bonding block is connected to a spring piece, and the other side of the spring piece is connected to the second movable cavity at the corresponding position.

[0015] Preferably, the bonding mechanism further includes a second limiting block: Multiple second limiting blocks are connected at one end to the two ends of the corresponding position fitting block. Multiple second limiting grooves are opened in the inner cavity of the second movable cavity. The outer side of the second limiting block is slidably connected to the corresponding position second limiting groove.

[0016] 1. In this invention, by setting up a lifting mechanism, a tool is used to rotate the control rod through the control slot. The first linear module drives the two first moving seats to move relative to each other. Through the linkage between the first rotating rod and the second rotating seat, the lifting plate is pushed to slide in the mounting box, so that the first connecting seat and the first bonding wheel have a height difference relative to the second bonding wheel. This makes the first bonding wheel and the second bonding wheel form a front-to-back height difference during the film application process. When there are raised structures on the surface of the power bank, the bonding wheel can better fit the raised area on the surface of the power bank, ensuring the film adhesion of the raised area and the effect of air bubble removal.

[0017] 2. In this invention, by setting a clamping mechanism, a tool is used to rotate the drive rod through the drive groove. The second linear module drives the two second moving seats to move relative to each other. The movement of the first connecting plate and the second connecting plate drives the clamping plate to clamp and fix the second rotating rod. The first bonding wheel is connected to the outside of the second rotating rod through the second connecting seat. When the second rotating rod rotates, it drives the first bonding wheel to deflect adaptively. The bonding angle is automatically adjusted according to the chamfer angle of the edge of the power bank, so that the first bonding wheel can tightly fit the chamfer surface when it is attached to the edge area of ​​the power bank. This avoids the protective film from lifting or wrinkling due to mismatched angles, and improves the film application quality in the edge area.

[0018] 3. In this invention, by setting up a bonding mechanism, the bonding block is always bonded to the outside of the second rotating rod under the elastic force of the spring sheet. When the clamping mechanism clamps the second rotating rod, the bonding block applies a continuous auxiliary friction force to the second rotating rod, which enhances the clamping effect of the clamping mechanism on the second rotating rod, keeps the bonding wheel stable during rolling, avoids uneven rolling or pressure caused by fluctuations in clamping force, ensures the smoothness of the bonding wheel rolling and the consistency of pressure during the film application process, and further improves the film application quality.

[0022] Please see Figures 1-4 It is understood that the present invention provides a technical solution: a protective film applicator for power bank production, comprising a driving device 1, an mounting box 2, and a clamping mechanism 5. One end of the mounting box 2 is installed on one side of the drive device 1. The inner cavity of the mounting box 2 is provided with a lifting mechanism 3. The lifting mechanism 3 includes a lifting plate 308. The outer side of the lifting plate 308 is slidably connected to the inner cavity of the mounting box 2. Both ends of one side of the lifting plate 308 are connected to a second rotating seat 307. Both sides of the bottom of the lifting plate 308 are connected to a first connecting seat 4. The second rotating seat 307 moves to drive the lifting plate 308 to slide in the mounting box 2, thereby driving the two first connecting seats 4 on the lifting plate 308 to move. Each of the two first connecting seats 4 has a first movable cavity 9 on one side, and two clamping mechanisms 5 are disposed in the corresponding first movable cavity 9. The clamping mechanism 5 includes two clamping plates 507 and a second connecting seat 511. A second movable cavity 10 is opened on one side of the clamping plate 507, and a fitting mechanism 6 is disposed in the second movable cavity 10. The lifting mechanism 3 also includes a first linear module 303 and a first rotating rod 306: The first linear module 303 is connected to one side of the inner cavity of the mounting box 2. Both ends of one side of the first linear module 303 are connected to the first movable seat 304. The first movable seat 304 is connected to the first rotating seat 305 on one side. One end of each of the two first rotating rods 306 is rotatably connected to one side of the first rotating seat 305 at the corresponding position, and the other end of each first rotating rod 306 is rotatably connected to one side of the second rotating seat 307 at the corresponding position.

The lifting mechanism 3 also includes a telescopic rod 309: Multiple telescopic rods 309 are connected at one end to a corresponding position on one side of the lifting plate 308, and at the other end to a corresponding position inside the mounting box 2. A return spring 310 is sleeved on the outside of the telescopic rod 309. One end of the return spring 310 is connected to a corresponding position on one side of the lifting plate 308, and at the other end to a corresponding position inside the mounting box 2.

[0023] Specifically, when it is necessary to adapt to the raised structure on the surface of the power bank, the operator uses a hex wrench to insert into the control slot 302 and rotates the control rod 301. The control rod 301 drives the lead screw inside the first linear module 303 to rotate. The lead screw drives the two first moving seats 304 to move relative to each other along the guide rail through the threaded engagement. The first rotating seat 305 drives the first rotating rod 306 to deflect. The first rotating rod 306 pushes the lifting plate 308 to slide in the mounting box 2 through the second rotating seat 307, so that the first contact wheel 7 on the first connecting seat 4 creates a height difference with the second contact wheel 8.

[0024] Please see Figures 5-6 It can be seen that the clamping mechanism 5 includes a second linear module 503, a second connecting plate 506, and a second rotating rod 510: The second linear module 503 is connected to the first movable cavity 9 at the corresponding position on one side. The second movable base 504 is installed at both ends of one side of the second linear module 503. The first connecting plate 505 is connected to one side of the second movable base 504. Two second connecting plates 506 are connected at one end to one side of the first connecting plate 505 at the corresponding position, and a clamping plate 507 is connected to one side of the second connecting plate 506. One end of the second rotating rod 510 is rotatably connected to the inner side of the first connecting seat 4. A through hole is provided on one side of the inner cavity of the first movable cavity 9. The other end of the second rotating rod 510 extends into the first movable cavity 9 through the through hole provided in the inner cavity of the first movable cavity 9 at the corresponding position. One end of the second rotating rod 510 is rotatably connected to the corresponding position in the inner cavity of the first movable cavity 9. A through hole is provided on one side of the second connecting seat 511. The outer side of the second rotating rod 510 is connected to the through hole provided in the second connecting seat 511. The clamping mechanism 5 also includes a drive rod 501: One end of the drive rod 501 is connected to one end of the second linear module 503. A rotating hole is provided in the inner cavity of the first movable cavity 9. The outer side of the drive rod 501 is rotatably connected to the rotating hole provided in the inner cavity of the first movable cavity 9 at the corresponding position. A drive groove 502 is provided at the other end of the drive rod 501. The clamping mechanism 5 also includes a first limiting block 508: Two first limiting blocks 508 are connected at one end to one side of the second movable seat 504 at the corresponding position. The first movable cavity 9 has first limiting grooves 509 at both ends on one side of the cavity. The outer side of the first limiting block 508 is slidably connected to the first limiting groove 509 at the corresponding position. The first bonding wheel 7 is connected to one side of the second connecting seat 511, and the second bonding wheel 8 is connected to the bottom of the mounting box 2.

[0025] Specifically, when it is necessary to adjust the deflection angle of the first bonding wheel 7 to adapt to the chamfer of the power bank edge, the operator uses a hex wrench to insert into the drive slot 502 and rotates the drive rod 501. The drive rod 501 drives the lead screw inside the second linear module 503 to rotate. The lead screw drives the two second moving seats 504 to move away from each other along the guide rail direction through the threaded engagement. The clamping plate 507 moves away from each other through the first connecting plate 505 and the second connecting plate 506, releasing the clamping of the second rotating rod 510. At this time, the second rotating rod 510 can rotate freely, causing the first bonding wheel 7 to automatically adjust the bonding angle according to the chamfer angle of the power bank edge. After the angle is adjusted to the correct position, the drive rod 501 is rotated in the opposite direction, and the two second moving seats 504 move closer to each other. The clamping plate 507 re-clamps the second rotating rod 510, locking the first bonding wheel 7 at the current angle. This design allows the first bonding wheel 7 to fit tightly against the chamfered surface when it is attached to the edge area of ​​the power bank, preventing the protective film from lifting or wrinkling.

[0026] Please see Figures 7-8 It can be seen that the bonding mechanism 6 includes a bonding block 601: The inner cavity of the second movable cavity 10 is provided with multiple through slots, and the outer sides of multiple fitting blocks 601 are slidably connected to the through slots provided in the inner cavity of the second movable cavity 10 at the corresponding positions. One side of the fitting block 601 is connected to a spring piece 604, and the other side of the spring piece 604 is connected to the second movable cavity 10 at the corresponding position. The bonding mechanism 6 also includes a second limiting block 602: Multiple second limiting blocks 602 are connected at one end to the two ends of the corresponding position fitting block 601. Multiple second limiting grooves 603 are opened in the inner cavity of the second movable cavity 10. The outer side of the second limiting block 602 is slidably connected to the corresponding position second limiting groove 603.

[0027] Specifically, when the clamping mechanism 5 clamps the second rotating rod 510, the bonding block 601 is always attached to the outside of the second rotating rod 510 under the elastic force of the spring piece 604, applying a continuous auxiliary friction force to the second rotating rod 510, which enhances the clamping effect of the clamping mechanism 5 on the second rotating rod 510, keeps the first bonding wheel 7 stable during rolling, avoids uneven rolling or pressure caused by fluctuations in clamping force, and ensures the smoothness of the bonding wheel rolling and the consistency of pressure during the film application process.

[0028] Working principle: When it is necessary to adapt to the raised structure on the surface of the power bank, the operator uses a hex wrench to insert into the control slot 302 and rotates the control rod 301. The control rod 301 drives the lead screw inside the first linear module 303 to rotate. The lead screw drives the two first moving seats 304 to move relative to each other along the guide rail through the threaded engagement. The first rotating seat 305 drives the first rotating rod 306 to deflect. The first rotating rod 306 pushes the lifting plate 308 to slide in the mounting box 2 through the second rotating seat 307, so that the first contact wheel 7 on the first connecting seat 4 creates a height difference with the second contact wheel 8. When it is necessary to adjust the deflection angle of the first contact wheel 7 to adapt to the chamfer of the power bank edge, the operator uses a hex wrench to insert into the drive slot 502 and rotates the drive rod 501. The drive rod 501 drives the lead screw inside the second linear module 503 to rotate. The lead screw drives the two second moving seats 304 to rotate through the threaded engagement. 04. Move relatively away along the guide rail direction. The clamping plate 507 moves relatively away through the first connecting plate 505 and the second connecting plate 506, releasing the clamping of the second rotating rod 510. At this time, the second rotating rod 510 can rotate freely, causing the first bonding wheel 7 to automatically adjust the bonding angle according to the chamfer angle of the edge of the power bank. After the angle is adjusted to the correct position, the drive rod 501 is rotated in the opposite direction, and the two second moving seats 504 move relatively closer. The clamping plate 507 clamps the second rotating rod 510 again, locking the first bonding wheel 7 at the current angle. When the clamping mechanism 5 clamps the second rotating rod 510, the bonding block 601 is always attached to the outside of the second rotating rod 510 under the elastic force of the spring piece 604, applying a continuous auxiliary friction force to the second rotating rod 510, enhancing the clamping effect of the clamping mechanism 5 on the second rotating rod 510, and keeping the first bonding wheel 7 stable during the rolling process.

[0029] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
