DETAILED DESCRIPTION OF THE EMBODIMENTS
[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts belong to the protection scope of the present utility model.
[0024] Please refer to Figure 1 、 Figure 2 and Figure 3 , the embodiment of the present utility model provides a mounting fixture, which includes a first suction cup 2 and a second suction cup 8 arranged oppositely. Both the first suction cup 2 and the second suction cup 8 have adsorption surfaces. The first suction cup 2 is driven to flip by a flipping mechanism, and the second suction cup 8 is driven to approach or move away from the first suction cup 2 by a lifting mechanism. Positioning mechanisms are provided on both the first suction cup 2 and the second suction cup 8. In this embodiment, a fixture is used to complete the mounting of the reflector and the Mini LED lamp board, making the process of pasting the optical reflective film material efficient and without polluting or damaging the film material. It is required that the pasting positions have good consistency, and there are no air bubbles, wrinkles or bulges between the optical film material and the lamp board 7 after pasting. Specifically, the first suction cup 2 and the second suction cup 8 are used to adsorb the reflector and the lamp board 7 respectively. The adsorption method can adopt vacuum adsorption, which is a conventional means and will not be elaborated here. Since there are many adsorption holes on the adsorption plate, when the optical reflective film material (reflector) covers the surface of the suction cup, the negative pressure on the surface of each small hole of the suction cup will suck the optical reflective film material. As long as the flatness of the holes is designed to be consistent, when tearing off the back glue protective film a on the surface of the sucked optical reflective film material, the film material will not move and contact the contaminated object, thus affecting the adhesive force of the back glue; the film tearing process will not cause the back glue to wrinkle or deform. Then, the first suction cup 2 is flipped by the flipping mechanism until the adsorption surface faces the adsorption surface of the second suction cup 8, and then the reflector and the lamp board 7 are fitted through the lifting mechanism. The positioning mechanism can ensure the position of the reflector on the first suction cup 2, and similarly, it can also ensure the position of the lamp board 7 on the second suction cup 8. A first air valve 3 is provided on the first suction cup 2 for supplying air. Similarly, a second air valve 9 is provided on the second suction cup 8 for supplying air. As Figure 4 shown, there is a layer of back glue protective film a on the reflector, which needs to be torn off before use. As Figure 5 and Figure 6 shown, it is a schematic diagram of the lamp board 7. It can be seen that there are several lamp beads b on the lamp board 7, and other devices c are provided on the back. The lamp board 7 and the reflector are both existing products.
[0025] Please refer to Figure 1 、 Figure 2 and Figure 3, the flipping mechanism includes a flipping shaft 18 passing through the first suction cup 2 and a rotary motor 5 for driving the flipping shaft 18 to rotate. In this embodiment, the flipping mechanism uses the rotary motor 5 to drive the flipping shaft 18 to rotate, thereby completing the flipping. The flipping mechanism can also be provided with a flipping limit block 4, a flipping bearing 16, etc. to achieve a stable flipping action. Preferably, the flipping bearing 16 and the flipping limit block 4 can be installed on the frame 17.
[0026] Please refer to Figure 1 , Figure 2 and Figure 3 , the positioning mechanism includes positioning pins provided on the first suction cup 2 and the second suction cup 8. In this embodiment, the positioning method uses positioning pins. Specifically, the positioning pins can be provided at the edge positions of the first suction cup 2 and the second suction cup 8, and multiple positioning pins are designed to achieve the positioning of the material. Preferably, the positioning pins are driven by a driving mechanism to extend and retract in the first suction cup 2 and the second suction cup 8. Here, the driving mechanism uses, for example, a cylinder 21. The cylinder 21 can control the extension and retraction of the positioning pins. Correspondingly, holes can be designed on the first suction cup 2 and the second suction cup 8 for the positioning pins to be placed. In addition to this positioning method, positioning lines can also be drawn on the first suction cup 2 and the second suction cup 8. By placing the square lamp panel 7 and the square reflector in the square formed by the positioning lines, when the edge of the material coincides with or is flush with the square, the positioning is completed to ensure accurate subsequent mounting. For the convenience of distinction, the positioning pin on the first suction cup 2 is defined as the first positioning pin 19, and the positioning pin on the second suction cup 8 is defined as the second positioning pin 20.
[0027] Please refer to Figure 1 , Figure 2 and Figure 3 , it further includes a frame 17. The first suction cup 2 and the second suction cup 8 are both installed on the frame 17, and the first suction cup 2 is located above the second suction cup 8. In this embodiment, setting the frame 17 allows the first suction cup 2 and the second suction cup 8 to be arranged as needed. For example, as shown in this embodiment, they are arranged vertically. Of course, since the adsorption method is used, even if they are not arranged vertically, it does not affect the mounting of the two materials. Designing the frame 17 can also be set through components such as a micrometer 6, a lifting slide plate 14, a guide post 15, a flipping bearing 16, a flipping limit plate, a bottom plate 12, an electric cylinder 11, etc.
[0028] Please refer to Figure 1 , Figure 2 and Figure 3, the lifting mechanism includes an electric cylinder 11 and a lifting slide plate 14 for supporting the second suction cup 8, and the driving end of the electric cylinder 11 is arranged on the lifting slide plate 14. In this embodiment, the lifting method adopts the cooperation of the electric cylinder 11 and the lifting slide plate 14. The electric cylinder 11 drives the lifting slide plate 14 to lift and lower, and the lifting slide plate 14 supports the second suction cup 8 so that it can approach or move away from the first suction cup 2. Of course, in addition to using the electric cylinder 11, existing linear driving methods can be used, such as screw drive, electric push rod, air cylinder, oil cylinder, etc., and this embodiment does not limit this.
[0029] Please refer to Figure 1 , Figure 2 and Figure 3 , a displacement table 10 is arranged between the lifting slide plate 14 and the second suction cup 8. In this embodiment, the design of the displacement table 10 can adjust the position of the second suction cup 8 as needed, so as to complete the fine adjustment in the XY direction. Preferably, the displacement table 10 can be manual or electric, and the displacement table 10 is also an existing component, and this embodiment does not limit this.
[0030] Please refer to Figure 1 , Figure 2 and Figure 3 , a hole for the guide post 15 to pass through is arranged on the lifting slide plate 14, and the lifting slide plate 14 slides along the extending direction of the guide post 15. In this embodiment, the lifting slide plate 14 can be guided by the guide post 15 to improve the lifting stability. A fixed seat 13 is arranged at the bottom of the guide post 15, and the fixed seat 13 is placed on the bottom plate 12.
[0031] Please refer to Figure 1 , Figure 2 and Figure 3 , flexible contact surfaces are arranged on both the first suction cup 2 and the second suction cup 8. In this embodiment, the design of the flexible contact surface can produce slight deformation at local slightly uneven positions, so that all points on the plane of the optical reflection film material can contact and be stressed against the lamp board 7, so that there are no bubbles or bulges between the optical reflection film material and the lamp board 7, and the adhesion and peeling force of each plane after the optical reflection film material is pasted are highly consistent. The flexible contact surface here is, for example, made of rubber material, and other existing flexible materials can be used, and this embodiment does not limit this.
[0032] Please refer to Figure 1 , Figure 2 and Figure 3, this fixture further includes a micrometer 6 for measuring parallelism. In this embodiment, the micrometer 6 can be used to measure parallelism and is provided on the frame 17 for convenient use by people. When manually using a dial indicator to measure the parallelism between the surface of the suction cup of the reflector 1 and the surface of the suction cup of the lamp board 7 when the suction cup of the reflector 1 is flipped 180°, the flipping limit mechanism is adjusted according to the parallelism value to ensure the parallelism of the two suction cup surfaces; at the same time, a dimensional measuring device is used manually to measure the actual offset of the center of the round hole of the just-pasted lamp board 7 and the reflector 1 relative to the center of the chip of the lamp board 7; the displacement stage 10 is adjusted in the XY direction according to the offset to ensure that the two center distances meet the positional tolerance requirements.
