Description

Technical Field

[0001] This utility model relates to a fixture for optical lenses, specifically an auxiliary positioning fixture for applying ink to optical lenses. Background Technology

[0002] An optical lens ink coating positioning fixture refers to a tool or device used to assist in positioning and fixing optical lenses during the ink coating process. Its main purpose is to ensure that the optical lens remains stable during ink coating, avoiding positional shifts or rotations, thereby improving the accuracy and efficiency of ink coating.

[0003] When using existing optical lens ink coating positioning fixtures, the optical lenses are usually fixed by direct contact between a rigid structure and the optical lens. In order to ensure the stability of the optical lens during ink coating, it is necessary to fix it in both the vertical and horizontal directions. This causes sliding friction between the optical lens and the rigid structure on the fixture, which can scratch the optical lens. Utility Model Content

[0004] The purpose of this utility model is to provide an auxiliary positioning fixture for ink coating of optical lenses. By setting an airbag and a pad to contact the optical lens, the optical lens is fixed in both the vertical and horizontal directions at the same time. This allows the optical lens to remain fixed during the ink coating process and avoids friction and scratches from hard structures such as the fixture plate.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary positioning fixture for coating optical lenses, comprising a support assembly, a negative pressure assembly, and multiple positioning assemblies disposed on the support assembly. The support assembly includes a fixture plate, an air chamber disposed inside the fixture plate, and multiple fixture slots arranged in a straight line on the upper surface of the fixture plate. Multiple positioning assemblies are respectively disposed within the multiple fixture slots, and each fixture slot is provided with an air extraction hole and a receiving groove. The negative pressure assembly includes a negative pressure device and an air extraction pipe fixedly connected to the negative pressure device. The end of the air extraction pipe away from the negative pressure device is fixedly connected to the fixture plate. The positioning assemblies include... The system includes an airbag, an air supply tube fixedly connected to the airbag, and a gasket positioned above the air supply tube. The airbag is a hollow cavity structure with openings at both ends. The air supply tube extends into the receiving groove and fits snugly against the inner wall of the receiving groove, preventing any gaps between the receiving groove and the air supply tube that could lead to gas leakage. This ensures that air in the receiving groove does not escape into the fixture groove. The gasket is equipped with sealing rubber and an inner sliding plate. A spring is fixedly connected to each inner sliding plate, with the end of the spring away from the inner sliding plate connected to the fixture plate. This allows the spring to pull the sealing rubber, the inner sliding plate, and the gasket within a certain range of motion, preventing the gasket from detaching from the receiving groove.

[0006] Preferably, an air outlet is provided below the air chamber, and the air chamber is connected to the air extraction pipe through the air outlet.

[0007] Preferably, each fixture slot is provided with multiple air extraction holes, and the fixture slot is connected to the air chamber through the air extraction holes therein.

[0008] Preferably, each fixture slot is provided with two receiving slots and two gaskets, with the two gaskets respectively located in the two receiving slots and symmetrical to the two sides of the airbag.

[0009] Preferably, the negative pressure assembly also includes a bracket, the negative pressure device is fixed on the bracket, and the bracket is fixedly connected to the lower end face of the fixture plate.

[0010] Preferably, the deformation rate of the airbag is linearly related to the negative pressure value of the air chamber.

[0011] Preferably, the two ends of the inner slide are connected to a sealing rubber and a gasket, respectively, and the sealing rubber is in contact with the inner wall of the receiving groove.

[0012] Preferably, the positioning component further includes a base plate, which is fixed in the fixture groove, and the airbag is fixed to the upper end face of the base plate.

[0013] Preferably, the gasket is C-shaped and positioned above the airbag.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model, by setting a negative pressure device under the fixture plate, draws air from the air chamber to form a negative pressure environment, and performs negative pressure adsorption on the optical lenses in multiple fixture slots. After negative pressure adsorption, the optical lenses do not directly contact each other, but are pressed on the airbag. When the airbag is subjected to pressure, it contracts, causing the pads on both sides to move into the fixture slot and automatically adhere to the sides of the optical lenses, fixing the bottom and sides of the optical lenses simultaneously (fixing the optical lenses in both vertical and horizontal directions). This allows the optical lenses to remain fixed during the ink coating process and avoids friction and scratches from hard structures such as the fixture plate, thereby improving the yield rate of optical lenses.

[0023] Please see Figure 1 One embodiment of this utility model is an auxiliary positioning fixture for applying ink to optical lenses, comprising a support component 1, a negative pressure component 2 and multiple positioning components 3 disposed on the support component 1.

[0024] Please see Figure 2 The support component 1 includes a fixture plate 11, with an air chamber 12 inside the fixture plate 11 and an air outlet 13 below the air chamber 12. The upper surface of the fixture plate 11 has multiple fixture slots 14 arranged in a straight line, and multiple positioning components 3 are respectively disposed in the multiple fixture slots 14. The negative pressure component 2 includes a negative pressure device 21 and a suction pipe 22 fixedly connected to the negative pressure device 21. The end of the suction pipe 22 away from the negative pressure device 21 is fixedly connected to the fixture plate 11. The air chamber 12 communicates with the suction pipe 22 through the air outlet 13. In this embodiment, the negative pressure device 21 is a negative pressure vacuum suction device, which evacuates the air chamber 12 through the suction pipe 22 to form a negative pressure environment. The negative pressure component 2 also includes a bracket 23. The negative pressure device 21 is fixed on the bracket 23, and the bracket 23 is fixedly connected to the lower surface of the fixture plate 11.

[0025] Please see Figure 3 Each fixture slot 14 is provided with multiple air extraction holes 15 and two receiving slots 16, and the fixture slot 14 communicates with the air receiving chamber 12 through the air extraction holes 15 therein. The multiple air extraction holes 15 in the fixture slot 14 are distributed in the circumferential direction of the airbag 31. The positioning component 3 includes the airbag 31, the air supply pipe 32 fixedly connected to the airbag 31, and the gasket 36 disposed above the air supply pipe 32. The airbag 31 is a cavity structure with openings at both ends and a hollow interior. The shape of the airbag 31 is... The rate of change is linearly related to the negative pressure value of the gas chamber 12, satisfying ΔV=K×P (where K=0.25±0.03mm / kpa). The gas supply pipe 32 extends into the receiving groove 16, and the gas supply pipe 32 is in close contact with the inner wall of the receiving groove 16. There will be no gap between the receiving groove 16 and the gas supply pipe 32, which would cause gas leakage, so that the air in the receiving groove 16 will not escape into the fixture groove 14. A sealing rubber 33 and an inner sliding plate 34 are provided on the gasket 36. In each inner sliding plate... Two springs 35 are fixedly connected to each of the inner slide plate 34. The ends of the two springs 35 away from the inner slide plate 34 are connected to the fixture plate 11, so that the springs 35 can pull the sealing rubber 33, the inner slide plate 34 and the gasket 36 within a certain range of motion, so that the gasket 36 will not detach from the receiving groove 16. Two gaskets 36 are provided in each fixture groove 14, and the two gaskets 36 are respectively provided in the two receiving grooves 16. The two ends of the inner slide plate 34 are respectively connected to the sealing rubber 33 and the gasket 36. The sealing rubber 33 fits against the inner wall of the receiving groove 16, so that there is no gap between the receiving groove 16 and the sealing rubber 33, which would cause gas leakage. The two gaskets 36 are symmetrical on both sides of the airbag 31. Therefore, there are two air supply pipes 32, sealing rubber 33, inner slide plate 34 and springs 35 in each fixture groove 14. The positioning component 3 also includes a base plate 37, which is fixed in the fixture groove 14, and the airbag 31 is fixed to the upper end face of the base plate 37.

[0026] Please see Figure 4 In this embodiment, the gasket 36 is C-shaped and is used to attach and fix the optical lens. The gasket 36 is made of rubber or silicone.

[0027] Please refer to the following: Figures 1 to 4 In the operation of this invention, the optical lens is placed on the airbag 31, and the negative pressure device 21 is driven to run. The air extraction pipe 22 is used to extract air from the air chamber 12, creating a negative pressure environment inside the air chamber 12. As a result, outside air enters the fixture slot 14 from above the fixture plate 11 and passes through the air extraction hole 15, causing the optical lens to also tend to press downward. The optical lens will directly press on the airbag 31 and apply pressure to the airbag 31, causing the air inside the airbag 31 to enter the two receiving slots 16 through the air supply pipes 32 at both ends, and push the two sealing rubbers 33 to move. This causes the two inner sliding plates 34 to drive the two pads 36 into the fixture slot 14, so that the two pads 36 contact the sides of the optical lens and fix it. In this way, the optical lens can be positioned without using a rigid structure, avoiding scratches.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
