Description

Technical Field

[0001] This invention relates to the field of film application technology, and in particular to a film application device and a cleaning device. Background Technology

[0002] During the production process of optical display panels, it is unavoidable that dust and other foreign objects will adhere to the surface of the optical display panels. In the existing technology, dust and other foreign objects on the surface of optical display panels are usually cleaned by cleaning equipment.

[0003] Cleaning equipment typically includes a film-applying device and a film-removing device. The film-applying device attaches a thin film to the surface of the optical display panel, adhering dust and other foreign matter to it. The film-removing device then peels the film off the panel, thus removing the dust and other contaminants. However, existing film-applying devices, due to their flawed design, require manual replacement when the film accumulates a significant amount of dust and other foreign matter, resulting in high labor costs. Summary of the Invention

[0004] The main objective of this invention is to provide a film-applying device that avoids the need for manual film replacement and reduces labor costs.

[0005] To achieve the above objectives, the present invention provides a film application device comprising:

[0006] Supporting institutions;

[0007] A feeding mechanism is located at one end of the support mechanism. The feeding mechanism includes a feeding roller for winding the film.

[0008] The system includes a film application mechanism and a recycling mechanism. The recycling mechanism is located at the end of the support mechanism away from the feeding mechanism, and the film application mechanism is located between the feeding mechanism and the recycling mechanism. The recycling mechanism includes a film take-up roller, and the film extends from the feeding roller to the film take-up roller. The film application mechanism is slidable along the length of the support mechanism and includes an application attachment for supporting the film so that the application attachment can press the film onto the surface of the material to be applied during sliding.

[0009] The recycling mechanism further includes a first drive assembly, which is drivenly connected to the take-up roller so that the take-up roller can rotate under the drive of the first drive assembly, thereby allowing the film to be wound from the feed roller onto the take-up roller via the attachment.

[0010] Optionally, the feeding mechanism further includes a first mounting base, which is mounted on one end of the support mechanism. A first support roller is mounted on the first mounting base. In the height direction of the film applicator, the height of the first support roller is higher than the height of the feeding roller and is comparable to the height of the applicator attachment. The first support roller is used to support the film so that the film passes sequentially from the feeding roller to the first support roller and the applicator attachment.

[0016] Optionally, the film application mechanism further includes a first base and a second base. The first base can slide along the length direction of the support mechanism, and the second base can move along the height direction of the first base. The film application attachment is mounted on the second base so as to slide along with the sliding of the second base.

[0017] Optionally, a third drive motor and a first lead screw are mounted on the first base, the first lead screw extending along the height direction of the first base, the third drive motor being driven by the first lead screw to move the first lead screw along the height direction of the first base, and the second base being connected to the first lead screw to move following the movement of the first lead screw; and / or,

[0018] The second base is also equipped with a support assembly, which is located below the attachment and supports the attachment.

[0019] Optionally, the film application mechanism further includes a second mounting base, which slides along the length of the support mechanism;

[0020] The film-applying mechanism further includes a pressure roller, which and the film-applying attachment are mounted on the second mounting base. The pressure roller is located on the side of the film-applying attachment facing the feeding mechanism. In the height direction of the film-applying device, the height of the pressure roller is higher than the height of the feeding roller and lower than the height of the film-applying attachment. The bottom of the pressure roller is used to press against the film. And / or,

[0021] The film application mechanism also includes an electrostatic eliminator, which and the film application attachment are mounted on the second mounting base. The electrostatic eliminator is located on the side of the film application attachment facing the feeding mechanism and is positioned close to the film to remove static electricity from the film.

[0022] Optionally, the support mechanism includes a support rail, and a third drive assembly is mounted on the side wall of the support rail; the recycling mechanism further includes a third mounting base, the first drive assembly and the film take-up roller are mounted on the third mounting base, the support rail is movably supported on the third mounting base by a second movable member, and the third mounting base is drivenly connected to the third drive assembly so that the third mounting base can reciprocate along the length direction of the support rail under the drive of the third drive assembly, thereby causing the film take-up roller to move closer to or further away from the feeding roller.

[0023] Optionally, the recycling mechanism further includes a third mounting base mounted on the support mechanism. A second support roller is mounted on the third mounting base. In the height direction of the film-applying device, the height of the second support roller is higher than the height of the take-up roller and approximately equal to the height of the applicator attachment. The second support roller supports the film so that after passing the applicator attachment, the film is wound onto the take-up roller via the second support roller; and / or,

[0024] The recycling facility also includes:

[0025] A third mounting base is mounted on the support mechanism, and a first pressure roller is mounted on the third mounting base;

[0026] The second pressing roller is disposed opposite to the first pressing roller to form a second pressing gap with the first pressing roller, the second pressing gap being used for the film to pass through;

[0027] The fourth drive assembly is connected to the second pressure roller drive and drives the second pressure roller to move closer to or away from the first pressure roller, so as to make the second pressure gap smaller or larger.

[0028] The present invention also proposes a cleaning device, which includes a film-peeling device and the aforementioned film-applying device, wherein the film-peeling device is used to separate the film from the surface of the material to be applied.

[0029] The technical solution of this invention, by setting up a feeding mechanism and a recycling mechanism, simultaneously extends the film from the feeding roller of the feeding mechanism to the take-up roller of the recycling mechanism, and then sets the film-applying mechanism between the feeding mechanism and the recycling mechanism, and the film-applying mechanism can slide along the length direction of the support mechanism, so that the film-applying attachment of the film-applying mechanism can squeeze the film onto the surface of the material to be applied during the sliding process, thereby realizing the film application work. When there is a lot of dust or other foreign matter adhering to the film and it needs to be replaced, the first driving component can be controlled to operate, so that the take-up roller rotates. During the rotation of the take-up roller, the used part of the film is gradually rolled up onto the take-up roller, while the unused part is pulled from the feeding roller to the film-applying attachment for use, thus completing the film replacement. In this way, the automatic replacement of the film can be achieved by controlling the operation of the first driving component, avoiding the need for manual operation to replace the film, reducing labor costs. Moreover, the automatic replacement method is simple and convenient, with high operating efficiency, improving the utilization efficiency of the film-applying device. Attached Figure Description

[0046] The following section will mainly describe the specific structure of the film application device.

[0047] Reference Figures 1 to 11 In this embodiment of the invention, the film application device includes:

[0048] Support structure 400;

[0049] The feeding mechanism 300 is located at one end of the support mechanism 400. The feeding mechanism 300 includes a feeding roller 310 for winding the film 100.

[0050] The support mechanism 400 comprises a film application mechanism 500 and a recycling mechanism 600. The recycling mechanism 600 is located at the end of the support mechanism 400 away from the feeding mechanism 300, and the film application mechanism 500 is located between the feeding mechanism 300 and the recycling mechanism 600. The recycling mechanism 600 includes a film take-up roller 610, and the film 100 extends from the feeding roller 310 to the film take-up roller 610. The film application mechanism 500 is slidable along the length of the support mechanism 400. The film application mechanism 500 includes an application attachment 510, which supports the film 100 so that the application attachment 510 can press the film 100 onto the surface of the material to be applied during sliding.

[0051] The recycling mechanism 600 further includes a first drive assembly, which is drivenly connected to the film-collecting roller 610 so that the film-collecting roller 610 can rotate under the drive of the first drive assembly.

[0052] This allows the film 100 to be wound from the feed roller 310 onto the take-up roller 610 via the attachment 510.

[0053] In this embodiment, the film-applying mechanism 500 slides along the length of the support mechanism 400.

[0054] There are many ways to do this. For example, in some embodiments, the support mechanism 400 includes a support rail 410, and a rack is installed on the side wall of the support rail 410, the rack extending along the length of the support rail 410; the film application mechanism 500 also includes a second mounting base 530, the support rail 410 is movably supported on the second mounting base 530 by a first movable member 421, the film application attachment 510 is installed on the second mounting base 530, and the second mounting base 530 is provided with a gear 520, the gear 520 meshing with the rack.

[0055] The gear 520 is engaged so that the second mounting base 530 can slide along the length 5 of the support rail 410. The first movable member 421 can be a first sliding block, which can slide along...

[0056] The support rail 410 slides along its length, and the first sliding block is supported by the second mounting base 530, allowing the second mounting base 530 to slide along the length of the support rail 410. In this embodiment, the gear 520 meshes with the rack, enabling the gear 520 to move stably and reliably along the length of the rack.

[0057] This causes the second mounting base 530 to move along the length of the support rail 410. The drive gear 5200 can move in several ways, such as manually, or by mounting a second drive motor 580 on the second mounting base 530. The shaft of the second drive motor 580 is connected to the gear 520, so that by controlling the rotation direction of the second drive motor 580, the gear 520 can drive the second mounting base 530 to perform linear reciprocating motion along the length of the support mechanism 400.

[0058] There are many possible configurations for the first drive assembly. For example, in some embodiments, the first drive assembly includes a first drive motor 611, a first transmission wheel 612, a synchronous belt 613, and a second transmission wheel 614.

[0059] The first drive motor 611 is connected to the first transmission wheel 612. A synchronous belt 613 connects the first transmission wheel 612 to the second transmission wheel 614. The second transmission wheel 614 is connected to the take-up roller 610, either directly or indirectly. During operation, the first drive motor 611 drives the first transmission wheel 612 to rotate, and the second transmission wheel 614 rotates under the influence of the synchronous belt 613, thereby driving the take-up roller 610 to rotate.

[0060] When applying a film to a material, such as an optical display panel 200, the device first places the optical display panel 200 on the application attachment 510 and the film 100. The optical display panel 200 is fixed to the application attachment 510 and the film 100 by gravity or other fixing mechanisms. The application attachment 510 can be a rubber roller. Then, the second drive motor 580 is controlled to work, causing the application attachment 510 to slide. During the sliding process, the application attachment 510 presses the film 100 onto the surface of the optical display panel 200, thereby adhering dust and other foreign objects on the surface of the optical display panel 200 to the film 100. After the film is peeled off, the dust and other foreign objects on the surface of the optical display panel 200 are removed. When the film 100 has accumulated a lot of dust and other foreign matter and needs to be replaced, the first drive component is controlled to work, causing the take-up roller 610 to rotate. During the rotation, the take-up roller 610 gradually winds up the used part of the film 100 onto the take-up roller 610, while simultaneously pulling the unused part from the feed roller 310 to the attachment 510 for use. In this way, the replacement of the film 100 is completed.

[0061] The technical solution of this invention, by setting up a feeding mechanism 300 and a recycling mechanism 600, extends the film 100 from the feeding roller 310 of the feeding mechanism 300 to the take-up roller 610 of the recycling mechanism 600. A film-applying mechanism 500 is then positioned between the feeding mechanism 300 and the recycling mechanism 600, and the film-applying mechanism 500 can slide along the length of the support mechanism 400. This allows the film-applying attachment 510 of the film-applying mechanism 500 to press the film 100 onto the surface of the material to be applied during the sliding process, thus achieving the film 100 application. When the film 100 has accumulated a large amount of dust or other foreign matter and needs to be replaced, the first drive component can be controlled to rotate the take-up roller 610. During rotation, the take-up roller 610 gradually winds up the used portion of the film 100 onto the take-up roller 610, while simultaneously moving the unused portion from the feeding roller 310 to the attaching attachment 510 for later use, thus completing the replacement of the film 100. In this way, the film 100 can be automatically replaced by controlling the operation of the first drive component, avoiding the need for manual replacement and reducing labor costs. Furthermore, the automatic replacement method is simple, convenient, and highly efficient, improving the overall efficiency of the film application device.

[0062] Regarding the feeding mechanism 300, in some embodiments, the feeding mechanism 300 further includes a first mounting base 320, which is mounted on one end of the support mechanism 400. A first support roller 321 is mounted on the first mounting base 320. In the height direction of the film applicator, the height of the first support roller 321 is higher than the height of the feeding roller 310 and approximately equal to the height of the applicator attachment 510. The first support roller 321 supports the film 100 so that the film 100 passes sequentially from the feeding roller 310 through the first support roller 321 and the applicator attachment 510. The arrangement of the first support roller 321 ensures that the film 100 has sufficient tension to reach the applicator attachment 510. To further improve the tension of the film 100, the feeding mechanism 300 may also include a first adhesive roller 322, which is located between the feeding roller 310 and the first support roller 321. The film 100 passes sequentially from the feeding roller 310 through the first adhesive roller 322 and the first support roller 321 to reach the applicator attachment 510.

[0063] In some embodiments, the feeding mechanism 300 further includes: a first mounting base 320, which is mounted on one end of the support mechanism 400, and a first pressing plate 323 is disposed on the first mounting base 320; a second pressing plate 324, which is disposed opposite to the first pressing plate 323 to form a first pressing gap 325 between the two plates, the first pressing gap 325 being used for the film 100 to pass through; and a second driving assembly 326, which is drivenly connected to the second pressing plate 324 to drive the second pressing plate 324 closer to or away from the first pressing plate 323, so that the first pressing gap 325 becomes smaller or larger. The second driving assembly 326 may include a first cylinder, which may be directly or indirectly connected to the second pressing plate 324. No specific limitation is made here, as long as the first cylinder can drive the second pressing plate 324 closer to or away from the first pressing plate 323. Before installing the film 100, the first clamping gap 325 between the second clamping plate 324 and the first clamping plate 323 can be relatively large. When installing the film 100, the film 100 is first wound onto the feeding roller 310, then one end of the film 100 is passed through the first clamping gap 325 and pulled up above the attachment 510, and finally wound onto the take-up roller 610 of the recycling mechanism 600. Then, by controlling the second drive assembly 326 to work, the second clamping plate 324 is brought closer to the first clamping plate 323, thereby pressing the film 100 between the first clamping plate 323 and the second clamping plate 324, and allowing the film 100 to move within the first clamping gap 325, so that the film 100 can be attached and replaced. This configuration increases the tension of the film 100, facilitating feeding by the feeding roller 310 and improving the flatness of the film 100. This allows the film 100 to adhere smoothly to the material to be bonded, effectively removing dust and other foreign matter from the surface of the material. Furthermore, the first cylinder can be connected to a first regulating valve 327, which controls the clamping force of the first cylinder to ensure that the pressure exerted on the film 100 by the first and second clamping plates 323 and 324 is moderate. This ensures that the film 100 has sufficient tension while allowing for normal bonding and replacement operations.

[0064] Regarding the film application mechanism 500, in some embodiments, the film application mechanism 500 further includes a first seat 531 and a second seat 532. The first seat 531 is slidable along the length direction of the support mechanism 400, and the second seat 532 is movable along the height direction of the first seat 531. The film application attachment 510 is mounted on the second seat 532 to slide along with the sliding of the second seat 532. There are many ways in which the second seat 532 can move along the height direction of the first seat 531. For example, the first seat 531 may be equipped with a third drive motor 541 and a first lead screw 542. The first lead screw 542 extends along the height direction of the first seat 531, and the third drive motor 541 is drivenly connected to the first lead screw 542 to drive the first lead screw 542 to move along the height direction of the first seat 531. The second seat 532 is connected to the first lead screw 542 to move along with the movement of the first lead screw 542. In this embodiment, the height of the five attached pieces 510 is adjusted by controlling the operation of the third drive motor 541, so as to adjust the tension of the film 100.

[0065] To prevent deformation of the attachment 510, in some embodiments, a support assembly is also installed on the second base 532. The support assembly is located below the attachment 510 and supports the attachment 510. The support assembly may include a support roller 551 and a reinforcing roller 552. The support roller 551 supports the reinforcing roller 552, and the reinforcing roller 552 supports the attachment 510.

[0066] In some embodiments, the film-applying mechanism 500 further includes a second mounting base 530, which slides along the length of the support mechanism 400; the film-applying mechanism 500 also includes a pressure roller 560, which and the film-applying attachment 510 are mounted on the second mounting base 530, and the pressure roller 560 is located on the side of the film-applying attachment 510 facing the feeding mechanism 300;

[0067] In the height direction of the film applicator, the height of the pressure roller 560 is higher than the height of the feeding roller 310 and lower than the height of the applicator 510. The bottom of the pressure roller 560 is used to press against the film 100.

[0068] The setting of the pressure roller 560 can apply downward pressure to the film 100, which on the one hand helps to improve the tension of the film 100, and on the other hand helps to improve the flatness of the film 100, thereby facilitating the flat adhesion of the film 100 to the material to be adhered, so as to effectively remove dust and other foreign objects from the surface of the material to be adhered.

[0069] In some embodiments, the film-applying mechanism 500 further includes an electrostatic eliminator 570, which, along with the film-applying attachment 510, is mounted on the second mounting base 530. The electrostatic eliminator 570 is located on the side of the film-applying attachment 510 facing the feeding mechanism 300, and is positioned close to the film 100 to remove static electricity from the film 100. That is, the film 100 undergoes electrostatic treatment before application to eliminate any static electricity carried by the film 100.

[0070] 5. Regarding the recycling mechanism 600, in some embodiments, the recycling mechanism 600 further includes a third mounting base 620, which is mounted on the support mechanism 400. A second support roller 630 is mounted on the third mounting base 620. In the height direction of the film-applying device, the height of the second support roller 630 is higher than the height of the film-receiving roller 610 and approximately equal to the height of the film-applying attachment 510.

[0071] The second support roller 630 supports the film 100 so that after the attachment 510 passes through it, the film 100 is wound onto the take-up roller 610 via the second support roller 630. The second support roller 630 provides sufficient tension for the film 100 to be pulled onto the take-up roller 610, facilitating the take-up roller 610's winding of the film 100. To further improve the tension of the film 100, the recovery mechanism 600 may also include a second adhesive roller 640, located between the take-up roller 610 and the second support roller 630. The film 100 passes sequentially through the second support roller 630 and the second adhesive roller 640 before being wound onto the take-up roller 610. In embodiments combining with the first support roller 321, the heights of the second support roller 630 and the first support roller 321 can be comparable or even the same, while the height of the attachment 510 is slightly higher than the heights of the second support roller 630 and the first support roller 321 to facilitate the attachment of the film 100.

[0072] Furthermore, to facilitate control of the tension of the film 100, the height of the second support roller 630 is adjustable. The adjustment method can be as follows: The third mounting base 620 includes a third base 621 and a fourth base 622. The third base 621 can slide along the length direction of the support mechanism 400. A fourth drive motor 651 and a second lead screw 652 are mounted on the third base 621. The second lead screw 652 extends along the height direction of the third base 621. The fourth drive motor 651 is driven by the third lead screw to drive it to move along the height direction of the third base 621. The fourth base 622 is connected to the second lead screw 652 to follow its movement. The second support roller 630 is mounted on the fourth base 622. Thus, by controlling the operation of the fourth drive motor 651, the height of the second support roller 630 can be adjusted to facilitate the adjustment of the tension of the film 100.

[0073] In some embodiments, the recycling mechanism 600 further includes: a third mounting base 620, which is mounted on the support mechanism 400, and a first pressing roller 661 is mounted on the third mounting base 620; a second pressing roller 662, which is disposed opposite to the first pressing roller 661 to form a second pressing gap 663 between them, the second pressing gap 663 being for the film 100 to pass through; and a fourth driving assembly 664, which is drivenly connected to the second pressing roller 662 and drives the second pressing roller 662 to move closer to or away from the first pressing roller 661, so that the second pressing gap 663 becomes smaller or larger. The fourth driving assembly 664 may include a second cylinder, which is connected or indirectly connected to the second pressing roller 662. No specific limitation is made here, as long as the second cylinder can drive the second pressing roller 662 to move closer to or away from the first pressing roller 661. Before installing the film 100, the second clamping gap 663 between the second clamping roller 662 and the first clamping roller 661 can be relatively large. When installing the film 100, the film 100 is first wound onto the feeding roller 310, and then the free end of the film 100 passes through the attachment 510 and through the second clamping gap 663 before being wound onto the take-up roller 610. Then, by controlling the fourth drive assembly 664, the second clamping roller 662 is brought closer to the first clamping roller 661, thereby pressing the film 100 between the second clamping roller 662 and the first clamping roller 661, and allowing the film 100 to move within the second clamping gap 663, ensuring that the film 100 can be applied and replaced. This setting can improve the tension of the film 100 and its flatness, which is conducive to the flat application of the film 100 to the material to be applied, effectively removing dust and other foreign objects from the surface of the material to be applied, and also facilitating the replacement of the film 100.

[0074] In some embodiments, the support mechanism 400 includes a support rail 410, and a third drive assembly 430 is mounted on the side wall of the support rail 410; the recycling mechanism 600 further includes a third mounting base 620, on which the first drive assembly and the film take-up roller 610 are mounted. The support rail 410 is movably supported on the third mounting base 620 via a second movable member 422. The third mounting base 620 is drivenly connected to the third drive assembly 430, so that the third mounting base 620 can reciprocate along the length direction of the support rail 410 under the drive of the third drive assembly 430, thereby causing the film take-up roller 610 to move closer to or further away from the feed roller 310. The second movable member 422 can be a second sliding block, which can slide along the length direction of the support rail 410 and is supported on the third mounting base 620, allowing the third mounting base 620 to slide along the length direction of the support rail 410. The third drive assembly 430 may include a fifth drive motor. By controlling the rotation direction of the fifth drive motor, the third mounting base 620 can reciprocate linearly along the length of the support rail 410, thereby making the distance between the film take-up roller 610 and the feed roller 310 adjustable, so as to adjust the tension of the film 100 and facilitate the application and recycling of the film 100.
