Description

Technical Field

[0001] The present invention relates to the technical field of 3D glass cover plate processing, and particularly relates to a 3D glass cover plate fitting jig. Background Art

[0002] In order to enable the glass cover plate to achieve functions such as light shielding and explosion prevention, and for the consideration of appearance beautification, a film is attached to the 3D glass cover plate. In the prior art, generally, the glass cover plate and the carrier film are respectively placed in the jigs of the male die and the female die and pressed to make them fit together. Generally, a deformable elastic silica gel is also placed between the female die and the carrier film to make the carrier film better receive force and be pressed and attached to the surface of the glass cover plate. The fitting process is generally that the midline position of the glass cover plate in the length direction first contacts the carrier film and gradually spreads to both sides and fits on the carrier film. During the fitting process, since the short side of the carrier film contacts the glass cover plate product before the middle part of the carrier film, it causes fitting defects such as glue overflow, glue scraping, bright lines, and bubbles. Summary of the Invention

[0003] To solve the technical problems in the background art, the present invention proposes a 3D glass cover plate fitting jig.

[0004] The 3D glass cover plate fitting jig includes: a male die and a female die. The convex bottom surface contour of the male die is a profiling contour that can fit the concave contour of the glass cover plate, and first bosses extending downward are respectively provided on both short sides adjacent to the profiling contour. The male die is also provided with vacuum suction holes penetrating the bottom surface and the top surface of the male die. A first groove for accommodating an elastic body is provided on the top surface of the female die, and the top surface of the elastic body can support the carrier film. When the male die adsorbing the glass cover plate moves downward close to the carrier film through the vacuum suction holes, the first bosses will touch the carrier film prior to the short sides of the glass cover plate.

[0005] Preferably, the height difference between the bottom surface of the first boss and the short side of the glass cover plate placed on the profiling contour of the male die is 1 mm.

[0006] Preferably, a plurality of horizontal first ventilation holes communicating the short sides of the glass cover plate with the atmosphere are provided on the first boss.

[0007] Preferably, second bosses are provided on both long sides of the carrier film of the female die, and the second bosses can perform horizontal limiting on the carrier film.

[0008] Preferably, a plurality of horizontal second ventilation holes communicating the long sides of the glass cover plate with the atmosphere are provided on the second boss.

[0009] Preferably, a plurality of guide hole grooves symmetrical to the first groove are provided on the top surface of the female die, and a plurality of guide posts extending downward and adapted to the guide grooves are provided on the male die.

[0010] Preferably, a plurality of air suction grooves communicating with the vacuum suction holes are further formed on the profiling contour of the bottom surface of the glass cover plate.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0012] By providing the first boss on the punch, the first boss contacts the carrier film prior to the short side of the glass cover plate, so that air bubbles, overflow glue, etc. generated during the fitting process of the carrier film and the glass cover plate will not be enclosed between them, but can be discharged from the short side, preventing poor fitting such as overflow glue, scraping glue, bright lines, and air bubbles, and improving the fitting yield.

[0013] In order to make the gas between the carrier film and the glass cover plate more easily discharged during the fitting process, a plurality of horizontal first vent holes communicating the short side of the glass cover plate with the atmosphere are formed on the first boss. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 1 FIG. is a schematic diagram of the overall structure of a 3D glass cover plate fitting jig proposed by the present invention.

[0015] Figure 2 FIG. is a schematic diagram of the structure of the punch and the glass cover plate of a 3D glass cover plate fitting jig proposed by the present invention.

[0016] Figure 3 FIG. is a schematic diagram of the structure of the punch of a 3D glass cover plate fitting jig proposed by the present invention. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The following will describe in detail the specific embodiments of the present invention with reference to the drawings.

[0018] Referring to Figures 1 to 3 , a 3D glass cover plate fitting jig includes: a punch 1 and a die 2. The protruding bottom surface contour of the punch 1 is a profiling contour 11 that can fit with the concave contour of the glass cover plate 3. First bosses 12 extending downward are respectively provided on both short sides adjacent to the profiling contour 11. Vacuum suction holes 13 penetrating the bottom surface and the top surface of the punch 1 are also formed on the punch 1. In practical applications, the vacuum suction holes 13 are communicated with one end of a vacuum tube, and the other end of the vacuum tube is communicated with a vacuum pump. A first groove 21 for accommodating an elastic body is formed on the top surface of the die 2. The top surface of the elastic body can support the carrier film. When the punch 1 adsorbing the glass cover plate 3 moves downward close to the carrier film through the vacuum suction holes 13, the first bosses 12 will touch the carrier film prior to the short side of the glass cover plate 3.

[0019] The working principle of the 3D glass cover laminating fixture is as follows: First, the glass cover is positioned and adsorbed on the bottom surface of the punch 1 with a profiling contour, and an elastomer such as silica gel that can be deformed under pressure is placed in the first groove 21 of the die 2. In practical applications, the silica gel should protrude from the first groove 21, and the top surface of the silica gel should be horizontal. Subsequently, the carrier film is placed on the top surface of the silica gel, and the punch 1 is moved downward through mechanisms such as a cylinder, so that the bottom surface of the punch 1 adsorbed with the glass cover 3 presses the carrier film and the silica gel elastomer. The midline position of the glass cover 3 in the length direction first contacts the carrier film and gradually spreads to both sides and adheres to the carrier film. Since during the lamination process, the first boss 12 contacts the carrier film prior to the short side of the glass cover 3, air bubbles, overflow glue, etc. generated during the lamination process between the carrier film and the glass cover 3 will not be trapped between them, but can be discharged from the short side, preventing lamination defects such as overflow glue, scraping glue, bright lines, and air bubbles, and improving the lamination yield rate.

[0020] In order to enable the first boss 12 to effectively prevent the short side of the glass cover 3 from prematurely contacting the short side of the carrier film and prevent the first boss 12 from being too high and damaging the carrier film, the height difference between the bottom surface of the first boss 12 and the short side of the glass cover 3 placed on the profiling contour 11 of the punch is 1 mm.

[0021] In order to enable the gas generated during the lamination process to be better discharged from the short side of the glass cover 3, a plurality of horizontal first vent holes 12a communicating the short side of the glass cover 3 with the atmosphere are provided on the first boss 12.

[0022] The die 2 is provided with second bosses 22 at the two long sides of the carrier film. The second bosses 22 can limit the carrier film in the horizontal direction. The second bosses 22 can not only enable the carrier film to be better positioned on the elastomer, but also prevent the carrier film from shifting during the extrusion lamination process.

[0023] In order to enable the gas generated during the lamination process to be better discharged from the long side of the glass cover 3, a plurality of horizontal second vent holes 22a communicating the long side of the glass cover 3 with the atmosphere are provided on the second bosses 22.

[0024] The die 2 is provided with a plurality of guide hole grooves 23 symmetric about the first groove 12 on the top surface, and the punch 1 is provided with a plurality of guide posts 14 extending downward and adapted to the guide grooves, so as to better align the glass cover on the punch 1 and the carrier film on the die 2 and ensure the lamination effect.

[0025] Refer to Figure 3 , in order to enable the glass cover 3 to be more reliably adsorbed on the punch 1, a plurality of air suction grooves 15 communicating with the vacuum suction holes 13 are further provided on the profiling contour 11 of the bottom surface of the glass cover 3.

[0026] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes should be covered within the protection scope of the present invention.
