Description

Technical Field

[0001] This invention relates to the field of film applicator technology, and more particularly to an automatic film applicator. Background Technology

[0002] Automatic film applicators automatically assemble small backlight modules on a fixture tray according to production process requirements. After the small backlight modules are placed on the tray, manual cleaning is required to ensure film application quality. However, manual cleaning is not only inefficient but also not thorough, resulting in a high failure rate for film application of small backlight modules.

[0003] The existing technology patent (patent number: 202122626608.3, patent name: an automatic film applicator with rapid dust removal function) extracts dust by setting up a fan, a dust suction pipe and a dust suction hood, and then discharges the dust to the outside through a dust discharge pipe.

[0004] However, the above-mentioned technology patent has the following problems: dust is discharged into the external environment through the dust exhaust pipe, which not only pollutes the external environment, but also affects the health of the staff when the dust is inhaled. Therefore, an automatic film applicator is proposed to solve the above problems. Summary of the Invention

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0030] Reference Figure 1 and Figure 6 An automatic film applicator includes a worktable 1, with a base 2 fixedly connected to the top of the worktable 1 for placing a backlight module. A storage slot 101 is provided on one side of the worktable 1, and a guide plate 7 is slidably connected within the storage slot 101. The guide plate 7 guides the rolling of a connecting cylinder 8. A second connecting plate 12 is fixedly connected to one end of the guide plate 7, and first connecting plates 6 are fixedly connected to both ends of the second connecting plate 12. A transverse rack 9 is fixedly connected to one side of the first connecting plate 6, and a connecting cylinder 8 is rotatably connected between the transverse racks 9. A dust-collecting mechanism is provided inside the connecting cylinder 8, which generates suction to remove the backlight module. The dust on the surface is sucked away, realizing the function of cleaning dust on the surface of the backlight component. Several rubber strips 18 are fixedly connected between the connecting cylinders 8. The rubber strips 18 are distributed in a circle. Several rubber rings 19 are fixedly connected to the inner side of the rubber strips 18. A support frame 5 is set on one side of the workbench 1. A hydraulic cylinder 4 is installed at the top of the support frame 5. A hydraulic shaft is fixedly connected to the output end of the hydraulic cylinder 4. The hydraulic cylinder 4 can provide power for pressing down the pressure plate 3. The pressure plate 3 is fixedly connected to the bottom end of the hydraulic shaft. Linkage components are set on both sides of the workbench 1. The linkage components enable the pressing action of the lower pressure plate 3 and the rolling action of the connecting cylinder 8 to be carried out simultaneously, improving the working efficiency of the device.

[0031] Please see Figure 3 The top of the guide plate 7 is provided with a placement groove 701. The bottom inner side of the placement groove 701 is provided with an anti-slip layer. The placement groove 701 can temporarily store the backlight module after the film is applied. The anti-slip layer can prevent the backlight module from sliding during the movement of the guide plate 7.

[0032] Please see Figure 4 and 5 The linkage assembly includes fixed blocks 14 fixedly connected to both sides of the worktable 1, a linkage gear 10 rotatably connected to one side of the fixed blocks 14, a connecting rod 13 fixedly connected to both sides of the pressure plate 3, and a longitudinal rack 11 fixedly connected to one end of the connecting rod 13. The longitudinal rack 11 meshes with the linkage gear 10, and the linkage gear 10 meshes with the transverse rack 9. The linkage assembly enables the pressing action of the lower pressure plate 3 and the rolling action of the connecting cylinder 8 to be performed simultaneously, thereby improving the working efficiency of the device.

[0033] Please see Figure 6 Several spiral lines 20 are fixedly connected to the inner side of the rubber strip 18. The spiral lines 20 are made of shape memory alloy (this type of shape memory alloy becomes straight when exposed to hot water and returns to a spiral shape after cooling). The cluster structure formed by the spiral lines 20 can filter dust. A friction rod 15 is fixedly connected to the center of one side of the connecting cylinder 8. The friction rod 15 is in contact with the spiral lines 20 and is made of rubber. The spiral lines 20 made of shape memory alloy will change from a spiral shape to a straight shape when exposed to hot water, reducing the obstruction function of the spiral lines 20 for dust and facilitating the quick removal of dust from the spiral lines 20. The friction between the spiral lines 20 and the friction rod 15 can make the spiral lines 20 generate static electricity. Electricity can adsorb dust on the surface of the backlight module, improving the cleaning efficiency of dust on the backlight module surface. One side of the connecting cylinder 8 is provided with an exhaust port 801, and the four sides of the connecting cylinder 8 are provided with air inlets 802. The connecting cylinder 8 can also provide installation protection for the dust collection mechanism. The dust collection mechanism includes a small air pump 16 installed inside the connecting cylinder 8 and an air collection cover 17 fixedly connected to the inner side of the connecting cylinder 8. The dust collection mechanism can generate suction to suck away the dust on the surface of the backlight assembly, realizing the dust cleaning function. The suction end of the connecting cylinder 8 is fixedly connected to an air suction pipe, which is fixedly connected to the air collection cover 17. The air collection cover 17 can realize the air collection function and enhance the dust collection power of the dust collection mechanism.

[0034] Please see Figure 3 and Figure 5 The top of the workbench 1 is located below the connecting cylinder 8 and a sewage tank 102 is provided. The outer wall of the workbench 1 is provided with a drain outlet, which is connected to the sewage tank 102. A sealing plug is provided in the drain outlet. The sewage tank 102 can temporarily store the sewage generated by the cleaning of the spiral line 20.

[0035] The small air pump 16 is existing technology, model VCH1028, which can realize the air suction function, and will not be described in detail here.

[0036] In use, the small backlight module is placed on the base 2, and then the hydraulic cylinder 4 is activated. The hydraulic cylinder 4 drives the pressure plate 3 to move downward through the hydraulic shaft. During the downward movement of the pressure plate 3, the longitudinal rack 11 is driven to move downward through the connecting rod 13. The downward movement of the longitudinal rack 11 drives the linkage gear 10 to rotate. The linkage gear 10 drives the transverse rack 9 to move. The transverse rack 9 drives the connecting cylinder 8 to move. The connecting cylinder 8 drives the rubber strip 18 and rubber ring 19 to move. When the rubber strip 18 and rubber ring 19 contact the backlight module, the friction between the rubber strip 18 and the backlight component causes the connecting cylinder 8 to drive the rubber strip 18 and rubber ring 19 to roll. At the same time, the small air pump 16 is activated, generating suction. Under the action of the air collection cover 17, the suction of the small air pump 16 can be further enhanced, thereby sucking away the dust on the surface of the backlight component and realizing the dust cleaning function of the backlight component surface.

[0037] The sucked-up dust is filtered out by the clusters formed by the spiral 20, leaving the dust residue in the spiral 20. When the connecting cylinder 8 drives the rubber strip 18 and rubber ring 19 to roll over the surface of the backlight assembly, the automatic cleaning function of the surface dust can be realized. At this time, the pressure plate 3 just contacts the backlight module. Then, the hydraulic cylinder 4 is controlled to drive the pressure plate 3 to move upward through the hydraulic rod, so that the pressure plate 3 is reset. Then, the lower diffuser, the brightness enhancement film, the brightness enhancement film and the light shield are placed on the backlight assembly in sequence. Then, the hydraulic cylinder 4 is controlled to drive the pressure plate 3 to move downward again through the hydraulic rod to realize the pressing function of the backlight assembly and the lower diffuser, the brightness enhancement film, the brightness enhancement film and the light shield.

[0038] After the pressing is completed, the hydraulic cylinder 4 is controlled to reset the pressure plate 3, and the backlight assembly with the film applied is placed in the placement slot 701 for temporary storage.

[0039] When the spiral 20 needs to be cleaned, the small air pump 16 can be turned off, causing the connecting cylinder 8 to move the spiral 20 above the sewage tank 102. Then, hot water is poured onto the spiral 20. At this time, the spiral 20 becomes straight, thereby reducing the obstruction function of the spiral 20 against dust. At the same time, the clusters formed by the spiral 20 will disintegrate, further reducing the filtration function against dust. This makes it easier for dust to detach from the spiral 20 and flow into the sewage tank 102 with the hot water, thus achieving the cleaning function of the spiral 20.

[0040] The above description is only a preferred embodiment 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.
