Description

Technical Field

[0001] The utility model relates to the technical field of lens production, in particular to a positioning fixture for producing anti-fog lenses. Background Art

[0002] The working principle of anti-fog glasses is mainly achieved through anti-fog coating, which is usually made of polymer materials and is hydrophilic, which can absorb moisture from the air. When the coating comes into contact with moisture, it will evenly distribute the moisture on the surface of the lens, forming a transparent film instead of forming fog. In this way, the lens can remain clear even in humid or temperature-different environments.

[0003] During the production process of the existing anti-fog lenses, the lenses need to be inspected, so a positioning fixture is needed to position and clamp the lenses. However, the existing positioning fixture is cumbersome to operate when clamping circular lenses of different sizes, which is not conducive to improving the inspection efficiency.

[0027] See also Figure 1-Figure 4 The utility model provides a positioning fixture for producing anti-fog lenses, comprising

[0028] A housing 1 and a positioning mechanism, wherein the positioning mechanism is installed in the housing 1;

[0029] The positioning mechanism is used to fix the anti-fog lens;

[0030] The positioning mechanism includes a rotating ring 3, an extrusion block 4 and a movable rod 5, and a clamping member 6 for fixing the anti-fog lens. The extrusion block 4 is fixedly connected to the inner wall of the rotating ring 3, and the extrusion block 4 can contact the movable rod 5. One end of the movable rod 5 passes through the side of the shell 1, and the movable rod 5 can slide. The rotating ring 3 can be rotatably installed in the shell 1, and the side of the rotating ring 3 is fixedly connected with a toggle rod 7.

[0031] It should be noted that the clamping member 6 is configured as a round rod;

[0032] The housing 1 is configured as an annular shell.

[0033] By adopting the above scheme, the anti-fog lens is placed in the annular hole of the housing 1 through the use of the positioning mechanism, and the toggle rod 7 is pushed to drive the rotating ring 3 to rotate, so that the squeezing block 4 squeezes the movable rod 5, and the movable rod 5 extends outward, driving the clamping member 6 to move outward, thereby clamping and fixing the anti-fog lens located in the annular hole of the housing 1;

[0034] When the anti-fog lens needs to be released from the position, the toggle rod 7 is pushed in the reverse direction to reset it, so that the movable rod can be retracted into the housing 1, and the clamping member 6 is separated from the anti-fog lens, thereby releasing the anti-fog lens from the position.

[0035] In this embodiment, a bearing 8 is fixedly installed in the housing 1 , the inner ring of the bearing 8 is rotatable, and the rotating ring 3 is fixedly connected to the inner ring of the bearing 8 .

[0036] It should be noted that the bearing 8 is configured as a damping bearing.

[0037] By adopting the above scheme, through the use of the bearing 8, when the toggle rod 7 is pushed to fix the anti-fog lens, the resistance is small, which facilitates the rotation of the rotating ring 3. When the anti-fog lens is in a fixed position, the reverse rotation resistance of the bearing 8 is large, which can maintain the stability of the anti-fog lens when it is positioned and will not loosen and fall spontaneously.

[0038] In this embodiment, a spring 9 is fixedly connected to the inner wall of the housing 1 , and one end of the spring 9 is fixedly connected to the movable rod 5 .

[0039] By adopting the above scheme, through the use of spring 9, when the squeezing block 4 squeezes the movable rod 5, the spring 9 is also compressed, and the spring 9 generates a reaction force. When the anti-fog lens is released, the reaction force of the spring 9 pushes the movable rod 5 to retract into the shell 1, so that the movable rod 5 is automatically reset, so that the squeezing block 4 can contact the movable rod 5 when the anti-fog lens is positioned next time, which is convenient for users to use.

[0040] In this embodiment, a support rod 10 is installed at the bottom of the housing 1;

[0041] In this embodiment, a damping shaft 11 is fixedly mounted on the bottom of the housing 1, and a sleeve 12 that is rotatably matched with the damping shaft 11 is fixedly connected to the upper end of the support rod 10;

[0042] The upper end of the support rod 10 is fixedly connected to a limit plate 13, and the limit plate 13 is used to limit the rotation range of the housing 1;

[0043] A support plate 14 is fixedly connected to the side of the support rod 10 , and a support platform 15 for placing an anti-fog lens is disposed on the support plate 14 .

[0044] It should be noted that the support rod 10 is fixedly mounted on a table or a plane;

[0045] The support platform 15 and the support plate 14 are configured as an integral structure.

[0046] By adopting the above scheme, through the use of the damping shaft 11, the position of the shell 1 after rotation can be self-locked, which can effectively prevent the shell 1 from rotating spontaneously. Through the coordinated use of the support plate 14 and the support platform 15, the shell 1 can be flipped over and fit with the support plate 14, so that the support platform 15 is located in the annular hole of the shell 1, and then the toggle lever 7 is operated to make the clamping member 6 position and clamp the anti-fog lens on the support platform 15, and then the shell 1 is flipped over and fits with the limit plate 13, so that the anti-fog lens can be tested, which can effectively reduce the risk of the anti-fog lens falling off when the user holds the anti-fog lens and cooperates with the clamping member 6 to position and clamp the anti-fog lens.

[0047] Specifically, the working principle of the positioning fixture for producing anti-fog lenses is as follows: when in use, the anti-fog lens is placed on the support table 15, the housing 1 is turned over and fits with the support plate 14, and the toggle rod 7 is pushed to drive the rotating ring 3 to rotate, so that the squeezing block 4 squeezes the movable rod 5, and the movable rod 5 extends outward, driving the clamping member 6 to move outward, thereby clamping and fixing the anti-fog lens;

[0048] When the anti-fog lens needs to be released from its position, the toggle rod 7 is pushed in the reverse direction to reset it, so that the movable rod can be retracted into the housing 1, the clamping member 6 is separated from the anti-fog lens, and the anti-fog lens is placed on the support platform 15, thereby releasing the anti-fog lens from its position and effectively preventing the anti-fog lens from falling when the positioning clamp is released.

[0049] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
