Description

Technical Field

[0001] The utility model relates to the field of film coating equipment, in particular to a surface film coating device for an intelligent display screen. Background Art

[0002] With the development of liquid crystal technology, liquid crystal panels have quickly become the protagonist of the display market with their many advantages. Mobile phones, portable game consoles, and manual operation platforms of industrial equipment use liquid crystal panels as display screens in many fields. In the production process of display screens, liquid crystal panels can complete the manufacturing process on the production line. The entire display screen manufacturing process involves multiple different processing steps and the flow of operations between different processes. After the display screen is produced, in order to prevent its surface from being accidentally scratched, a protective film needs to be applied to its surface. The film application methods on the market are mostly done manually, which is very inefficient and the quality of the film application is difficult to guarantee.

[0003] The prior art (announcement number: CN108819210A, announcement date: 2018.11.16) discloses an automatic film laminating machine, which can greatly improve the efficiency of laminating protective films for display screens of digital products, reduce scratches on the product surface caused by manual laminating, and improve product quality.

[0004] However, in the above scheme, a single-sided self-adhesive film is conveyed by a feed roll, which is cut by a film cutting cylinder before the film is pasted. Since the single-sided self-adhesive film on the market generally has a layer of release paper pasted on its adhesive surface, and this scheme does not have a material roller for recovering the release paper, it is only applicable to single-sided self-adhesive film without release paper. This type of film is similar to an adhesive tape. After a section of the film is pulled out, dust is easily adhered to the adhesive surface, causing dust to easily enter between the film and the display screen, seriously affecting the film pasting effect.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] like Figure 1-4 As shown, a surface coating device of an intelligent display screen of the utility model comprises a frame 1, on which a workbench 2 is fixedly mounted;

[0031] A film conveying mechanism 3 and a laminating mold 4 are fixedly installed on the workbench 2. The film conveying mechanism 3 includes a feeding roller 31, a peeling roller 32, a receiving roller 33 and a waste roller 34. The feeding roller 31, the peeling roller 32, the receiving roller 33 and the waste roller 34 are all rotatably mounted on the workbench 2.

[0032] A film roll 5 is placed at the unwinding roller 31, and a release layer 6 is pasted on the adhesive surface of the film roll 5. The unwinding roller 31 is provided with a release layer 6 by a stripping roller 32, and the stripped release layer 6 is recovered by a receiving roller 33;

[0033] The laminating mold 4 is installed between the stripping roller 32 and the waste roller 34. The film roll 5 is input into the laminating mold 4. When the laminating mold 4 is closed, a film of a suitable size is cut on the film roll 5 and a laminating operation is performed. The cutting waste generated by the laminating mold 4 is recovered through the waste roller 34.

[0034] The principle is: when in use, a film roll 5 is placed at the unwinding roller 31, and the film roll 5 is pulled out to pass through the laminating mold 4 and then recycled through the waste roller 34. It should be noted that before the film roll 5 is input into the laminating mold 4, it is necessary to manually peel off the release layer 6 and let the release layer 6 pass through the peeling roller 32 on the bottom side, and then put the display screen into the laminating mold 4. When the equipment starts working, the film roll 5 can automatically peel off the release layer 6 and then be transported to the laminating mold 4 for cutting and laminating operations, which can effectively prevent dust from sticking to the adhesive layer of the film roll 5, thereby ensuring its laminating effect on the display screen.

[0035] Further: the laminating mold 4 includes a mold frame 41, an upper mold 42 and a lower mold 43, the lower mold 43 is fixedly installed on the bottom side of the mold frame 41, the upper mold 42 is lifted and slidably installed in the mold frame 41, and the upper mold 42 is located above the lower mold 43;

[0036] A display screen placement groove 7 is formed on the upper side of the lower mold 43, and a knife groove 8 is provided at the outer edge of the display screen placement groove 7, and the knife groove 8 is integrally formed on the lower mold 43;

[0037] A pressing plate 9 is fixedly installed on the bottom side of the upper mold 42, and the pressing plate 9 is installed in the display screen placement groove 7 with a clearance fit. A film cutting knife 10 is arranged on the outer side of the pressing plate 9, and the film cutting knife 10 is fixedly installed on the bottom side of the upper mold 42, and the bottom side edge of the film cutting knife 10 is inserted into the knife groove 8 with a clearance fit.

[0038] When the mold is closed, the film cutting knife 10 can be just inserted into the knife groove 8 to complete the cutting of the film material roll 5, so that the film is cut into a suitable size and covered on the display screen, realizing the automatic cutting and film sticking action.

[0039] Furthermore: a vacuum cavity 11 is formed in the upper mold 42, and a vacuum adsorption groove 12 is formed at the bottom edge of the upper mold 42. The vacuum cavity 11 and the vacuum adsorption groove 12 are interconnected, and the vacuum adsorption groove 12 is located between the pressing plate 9 and the film cutting knife 10; excess air can be extracted from the gap between the film and the display screen by vacuuming, thereby ensuring the effect of film sticking and no bubbles are generated.

[0040] Furthermore, a vacuum hole 13 is fixedly installed on the side of the upper mold 42 , and the vacuum hole 13 is connected to the vacuum chamber 11 , so that the operation of vacuuming the vacuum chamber 11 can be facilitated.

[0041] Furthermore: a plurality of roller frames 14 are fixedly installed on the workbench 2, and the plurality of roller frames 14 are arranged in an array at equal distances from each other. A transmission roller 15 and an abutment roller 16 are rotatably installed in the roller frame 14, and the abutment roller 16 is abutted against the bottom side of the transmission roller 15. The transmission roller 15 and the abutment roller 16 rotate in opposite directions, and the film roll 5 is input between the transmission roller 15 and the abutment roller 16; this can ensure the stable transportation of the film roll 5 with high transportation accuracy, thereby ensuring the quality of film lamination.

[0042] Furthermore: several roller frames 14 are arranged on the left side of the laminating mold 4, and the abutment roller 16 in the rightmost roller frame 14 is used as a peeling roller 32. The peeled release layer 6 is transported to the receiving roller 33 through the abutment rollers 16 in the several roller frames 14; the abutment roller 16 can be used as a peeling roller 32 to push away the release layer 6 and then input it into the laminating mold 4, which can effectively reduce the influence of dust on the film.

[0043] This embodiment does not impose any formal restrictions on the shape, material, structure, etc. of the utility model. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the utility model are within the protection scope of the technical solution of the utility model.
