Description

Technical Field

[0001] This utility model relates to the field of lens processing technology, and in particular to an optical lens testing fixture. Background Technology

[0002] Existing blue light blocking lenses require blue light protection testing before leaving the factory. For example, Chinese Patent Publication No. CN217878281U discloses an optical lens testing fixture, including a base plate, a support frame on the base plate, a circular frame plate on the support frame, a circular guide groove on the upper surface of the circular frame plate, several sliding blocks sliding within the circular guide groove, a strip track on the sliding blocks, a support assembly for placing optical lenses sliding on the strip track, a telescopic frame that can extend and retract vertically on the base, a horizontal plate at the moving end of the telescopic frame, and a blue light irradiation lamp on the horizontal plate above the circular frame plate. The position of the support assembly can be adjusted according to the different sizes and specifications of the optical lenses, allowing for the fixing of optical lenses of different sizes. In addition, the optical lenses can be tested by irradiation with the blue light lamp, making the testing process extremely convenient and meeting people's needs.

[0003] However, the above-mentioned patent structure can only detect different positions of the same horizontal plane of the optical lens. When the user needs to detect different angles of the optical lens, it is not convenient to clamp the rotated optical lens. The detection area is not complete and there are blind spots in the detection. Utility Model Content

[0019] The following detailed description provides various embodiments or examples for implementing this utility model. Of course, these are merely embodiments or examples and are not intended to be limiting. Additionally, repeated reference numerals, such as repeated numbers and / or letters, may be used in different embodiments. These repetitions are for the purpose of simple and clear description of this utility model and do not represent a specific relationship between the different embodiments and / or structures discussed.

[0020] like Figures 1-5 An optical lens testing fixture is shown, comprising a fixed bottom ring 1, a rotating ring 2 rotatably disposed on the fixed bottom ring 1, and a fixed clamping assembly and a movable clamping assembly for clamping an optical lens 10 disposed on opposite sides of the rotating ring 2. The fixed clamping assembly includes an L-shaped frame 3 fixedly disposed on the rotating ring 2, and a first elastic clamp 4 rotatably mounted on the other end of the L-shaped frame 3. The movable clamping assembly includes a support base 5, a sliding seat 6 slidably disposed laterally on the support base 5, and a second elastic clamp 7 rotatably mounted on the sliding seat 6.

[0021] When inspecting the optical lens 10, the optical lens 10 can be clamped by the first elastic clamp 4 and the second elastic clamp 7 on the fixed clamping assembly and the movable clamping assembly. The first elastic clamp 4 and the second elastic clamp 7 can rotate, thereby adjusting the angle of the optical lens 10. At the same time, the rotating ring 2 can rotate horizontally relative to the fixed bottom ring 1, which makes it convenient for the user to inspect the optical lens 10 at different angles. In addition, the second elastic clamp 7 can slide with the sliding seat 6, thereby clamping optical lenses of different specifications, which is quite practical.

[0022] See Figure 1 , Figure 3 , Figure 5As shown, a rack 21 is provided on the lower side of the sliding seat 6, and a first rotating shaft 22 is provided in the support seat 5. A gear 23 and a worm gear 24 are respectively provided on the first rotating shaft 22. The gear 23 meshes with the rack 21. A worm gear 25 that meshes with the worm gear 24 is also provided in the support seat 5. One end of the worm gear 25 extends out of the support seat 5 and is provided with a knob 26.

[0023] During operation, the worm gear 25 is rotated by rotating the knob 26 to cooperate with the turbine 24. The turbine 24 drives the gear 23 to rotate through the first rotating shaft 22. The gear 23 meshes with the rack 23, thereby driving the sliding seat 6 to move through the rack 23. The movement of the sliding seat 6 drives the second elastic chuck 7 to move, thereby enabling the clamping of optical lenses of different sizes through the first elastic chuck 4 and the second elastic chuck 7.

[0024] See Figure 3 , Figure 4 As shown, an extension plate 31 connected to a second elastic clamp 7 is provided at the upper end of the sliding seat 6. The second elastic clamp 7 includes a fixed shaft 32 and a rotating sleeve 33 rotatably sleeved on the fixed shaft 32. The other end of the fixed shaft 32 is fixedly connected to the extension plate 31. A clamp 34 is provided at the other end of the rotating sleeve 33. A clamping groove 35 is provided on one side of the clamp 34. An elastic clamping member is provided in the clamping groove 35.

[0025] It should be noted that the second elastic clamp 7 has the same structure as the first elastic clamp 4, and the fixing shaft 32 of the second elastic clamp 7 is located on the L-shaped frame 3; in addition, the fixing shaft 32 of the second elastic clamp 7 and the first elastic clamp 4 are on the same axis.

[0026] See Figure 3 As shown, the elastic clamping member includes a movable rod 41 that passes vertically through the clamping slot 35. A clamping plate 42 is provided at the lower end of the movable rod 41 and inside the clamping slot 35. A first spring 43 is connected between the clamping plate 42 and the upper wall of the clamping slot 35. The first spring 43 is sleeved on the movable rod 41. Under the action of the first spring 43, the optical lens 10 is clamped by the cooperation of the clamping plate 42 and the clamping slot 35. The structure is simple and the operation is convenient.

[0027] See Figure 4As shown, an extension post 51 is provided on the upper side of the rotating sleeve 33, and a circular groove 52 communicating with the rotating sleeve 33 is provided at the inner end of the extension post 51. A second spring 53 and a positioning steel ball 54 are provided in the circular groove 52. Multiple positioning grooves 55 that cooperate with the positioning steel ball 54 are provided along the circumference on the outer wall of the fixed shaft 32. Thus, when the rotating sleeve 33 drives the chuck 34 to rotate, under the action of the second spring 53, the positioning steel ball 54 abuts against the positioning groove 55, thereby achieving the positioning of the rotating sleeve 33 and improving the stability during optical lens testing.

[0028] In this utility model, a mounting plate 71 is provided on the outer side of the fixed bottom ring 1, and a mounting through hole 72 is provided on the mounting plate 71. When testing optical lenses of the same batch, the fixed bottom ring 1 can be fixed, that is, it can be connected to the testing equipment by passing a bolt through the mounting through hole 72. Of course, in order to facilitate the movement of the fixed bottom ring 1, it can also be left unfixed.

[0029] Based on the accompanying drawings and the foregoing display and description of the basic principles, main features, and advantages of this utility model, those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
