[0027] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application is further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application and do not limit the present application.

[0028] Ensuring the yield of optical lens grinding can ensure the quality of optical lens, and specific advantages include eliminating defects such as scratches and pitting, making the lens surface smooth and flawless.

[0029] In the prior art, the optical lens is generally placed on the frame body for grinding, and in order to generally ensure the accuracy of grinding, the frame body is generally made of hard material. Therefore, during polishing, the optical lens may be worn between the optical lens and the frame body, thereby reducing the yield of the optical lens.

[0030] For this purpose, please refer to Figure 1 The optical lens grinding jig provided by the embodiments of the present application can reduce the wear between the optical lens and the frame body by placing the optical lens on the support seat 20 with smaller hardness, thereby improving the yield of the optical lens.

[0031] Specifically, the optical lens grinding jig comprises a base 10 and a support seat 20. The base 10 is formed with a water flow hole 10a, and the support seat 20 is arranged at the upper end of the base 10 along the first direction XX. In the embodiments of the present application, the first direction XX can be the thickness direction of the support seat 20 and the base 10. The support seat 20 is formed with a placing groove 20a for placing the optical lens to be ground. The groove bottom of the placing groove 20a is surrounded by an opening 20b, and the opening 20b is in communication with the water flow hole 10a along the first direction XX. The hardness of the support seat 20 is smaller than the hardness of the base 10. Therefore, during grinding, the wear between the support seat 20 and the optical lens is relatively small due to the smaller hardness of the support seat 20 than the hardness of the base 10, thereby improving the yield of the optical lens after grinding. The hardness of the base 10 is relatively large, which can also increase the strength of the jig and prevent the jig from deforming.

[0032] In order to maintain the stability of the optical lens during the grinding process, the side edge of the optical lens is in close contact with the side wall of the placing groove 20a, thereby reducing the grinding error caused by the shaking or deflection of the lens, and improving the grinding precision and product quality. The support seat 20 is designed during the processing and manufacturing of the support seat 20.

[0033] And it can be understood that the area ratio A of the opening 20b to the optical lens satisfies 0.8≤A≤1, and specifically can be 0.8, 0.85, 0.9, 1 or a range between any two of the above values, so that the area of the opening 20b is sufficient, thereby reducing the contact area between the support seat 20 and the optical lens, thereby reducing the risk of scratching.

[0034] When the optical lens is polished, the polishing mechanism is generally driven by a mechanical arm to polish the optical lens. In order to improve the polishing effect, a water solution (also known as "polishing liquid") is used to spray the polishing position, so as to form a lubricating film between the polishing mechanism and the optical lens, reduce friction, reduce wear, and make the optical lens more easily achieve a smooth surface during polishing. In addition, the polishing liquid can quickly take away the heat generated during polishing, thereby reducing the temperature of the polishing mechanism and the optical lens, and preventing thermal stress and deformation caused by overheating.

[0035] The water solution can flow out through the contact between the optical lens and the side wall of the placing groove 20a, and then be discharged through the opening 20b and the water outlet hole 10a at the lower end or be collected and treated. Further explanation is not given here.

[0036] Specifically, the material of the base 10 includes at least one of aluminum alloy and stainless steel; the material of the support seat 20 includes at least one of polytetrafluoroethylene and polyether ether ketone. The above-mentioned materials are easy to obtain and have low cost. In addition, polytetrafluoroethylene and polyether ether ketone have sufficient flexibility, so that the friction between the optical lens and the support seat 20 is small, thereby improving the yield of the polished glass.

[0037] Please refer to Figures 1-2 The support seat 20 is formed with at least one material taking port 20c. The material taking port 20c penetrates the support seat 20 along the first direction XX, and the material taking port 20c is in communication with the placing groove 20a. The material taking port 20c is arranged so that the optical lens can be quickly and conveniently taken out from the support seat 20 after polishing. Without the need to disassemble the entire support seat 20 or jig from the equipment, the material taking time and labor cost are greatly saved. Especially for the automatic or semi-automatic polishing production line, the material taking port 20c can be used in cooperation with the mechanical arm or other automatic material taking device to realize efficient automatic material taking operation.

[0038] On the other hand, by directly taking out the lens through the material taking port 20c, the lens surface can be avoided from being directly contacted by tools or hands, thereby reducing the risk of lens scratching or pollution caused by improper operation.

[0039] Further, please refer to Figures 1-2Two material taking openings 20c are formed on the support base 20 and are arranged on both sides of the placement groove 20a along the second direction YY. The two material taking openings 20c allow the optical lens to be taken out from both sides of the placement groove 20a simultaneously or separately after the grinding is completed, thereby increasing the flexibility and convenience of material taking.

[0040] In addition, the two material taking openings 20c allow the optical lens to be taken out from both sides of the placement groove 20a simultaneously or separately after the grinding is completed, thereby increasing the flexibility and convenience of material taking.

[0041] Please refer to Figure 3 The base 10 is formed with at least one auxiliary material taking groove 10b corresponding to the material taking opening 20c. In this way, when the optical lens is taken out through the material taking opening 20c, there is a deeper avoiding area to facilitate the taking out of the optical lens.

[0042] Further, the base 10 is formed with a groove 10c, and the water flow hole 10a penetrates the groove bottom of the groove 10c along the first direction XX. The groove 10c allows the aqueous solution to enter the groove 10c first during the grinding process and then be discharged through the water flow hole 10a, thereby reducing the retention and diffusion of waste liquid in the equipment and reducing the pollution risk to the environment and the lens.

[0043] By timely removing the aqueous solution and debris generated during the grinding process, the design of the groove 10c and the water flow hole 10a helps to reduce the erosion and wear of the base 10 and the support base 20 by these substances, thereby prolonging the service life of the equipment.

[0044] Specifically, please refer to Figure 3 The water flow hole 10a includes a first water flow hole 101a and a second water flow hole 102a along the first direction XX. The first water flow hole 101a is closer to the support base 20 than the second water flow hole 102a. From far away from the second water flow hole 102a to close to the second water flow hole 102a, the cross-sectional area of the first water flow hole 101a gradually decreases.

[0045] In this way, the first water flow hole 101a with a larger cross-sectional area can quickly discharge the waste liquid, reduce the accumulation and retention of the aqueous solution in the grinding area, and further improve the accuracy and stability of the grinding.

[0046] Please refer back to Figure 2 The base 10 is formed with a first mounting hole 10d, and the support base 20 is formed with a second mounting hole 20d. The optical lens grinding jig further includes a fastener (not shown in the figure). The fastener passes through the first mounting hole 10d and the second mounting hole 20d to relatively fix the base 10 and the support base 20. Along the first direction XX, the fastener does not exceed the side of the support base 20 away from the base 10.

[0047] The fastener can be a screw, a bolt, etc. without limitation, as long as it can fix the base 10 and the support seat 20 relatively, and the fastener does not occupy extra space on the surface of the support seat 20, which provides a larger working area for optical lenses of different specifications and sizes. Therefore, this design makes the jig more flexible to adapt to the grinding needs of lenses of different specifications.

[0048] The fastener does not protrude onto the working surface of the support seat 20, thereby avoiding the risk of collision or friction with the lens or other components during grinding, and being able to give the robot more operating space, avoiding affecting the operation of the robot.

[0049] In addition, the fastener does not protrude onto the working surface of the support seat 20, which can also effectively reduce the occurrence of the "cut hand" phenomenon.

[0050] The above are preferred embodiments of the present application, which do not limit the protection scope of the present application, so: any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
