Description

Technical Field

[0001] This utility model relates to the field of optical lens manufacturing technology, specifically to an optical lens thickness detection device. Background Technology

[0002] When optical lenses are manufactured, it is often necessary to measure the thickness of the optical lenses after production. The mechanical structure of the optical lens thickness detection device usually includes a base, which is usually made of high-precision marble or cast iron. It has good stability and rigidity, and can provide stable support for the entire detection device, reducing the impact of external vibration and deformation on the detection results.

[0003] Existing optical lens thickness detection devices still have the following problems when in use: their lens clamping mechanisms have certain compatibility issues, that is, they are limited to the lenses to be detected. Existing detection devices may only be applicable to optical lenses of specific shapes. For some special lenses, such as irregularly shaped lenses or lenses with complex external structures, they cannot be properly fixed and clamped, and thus cannot cooperate with the measuring mechanism to accurately obtain their thickness information.

[0023] Please see Figures 1-5In this embodiment of the present invention, a thickness detection device for an optical lens includes a fixing mechanism 1, which includes a fixing chamber 11. The fixing chamber 11 is equipped with a measuring mechanism 2 and a lens clamping mechanism 3. The bottom wall of the fixing chamber 11 has four sliding grooves 14 at equal angles. The lens clamping mechanism 3 includes a slide block 31 slidably connected to the sliding groove 14. A clamping block 36 is fixedly connected to the top of the slide block 31. The four clamping blocks 36 are all arranged in the fixing chamber 11 at equal angles. The fixing chamber 11 is equipped with a set of clamping block 36 structures, which includes four clamping blocks 36 arranged at equal angles. The bottom of the four clamping blocks 36 is equipped with a synchronous drive mechanism, which can drive the four clamping blocks 36 to move synchronously towards each other or away from each other, so as to clamp or release the lens in the fixing chamber 11. It can be adapted to fix irregularly shaped lenses or lenses with complex external structures, ensuring that the measuring head, i.e., the scale rod 24, can accurately measure along the contour of the lens, thus improving the versatility of the device.

[0024] A connecting column 32 is fixedly connected to the center of the bottom of the slide block 31. A bolt 33 is fixedly connected to the center of the outer bottom wall of the fixed chamber 11. A rotating sleeve 34 is rotatably installed on the outside of the bolt 33. Four elastic metal strips 35 are fixedly connected to the annular outer wall of the rotating sleeve 34 at equal angles. The end of the elastic metal strip 35 away from the rotating sleeve 34 is fixedly connected to the connecting column 32 on its corresponding side. An optical lens to be thickness-tested is placed on the inner bottom wall of the fixed chamber 11. The rotating sleeve 34 can be rotated to pull the connecting column 32 through the four elastic metal strips 35, thereby driving the slide blocks 31 in the four slide grooves 14 to move synchronously in opposite directions. That is, the four clamping blocks 36 can clamp the optical lens in the fixed chamber 11 in opposite directions. At this time, the nut of the bolt 33 can be turned to press the rotating sleeve 34 to complete the clamping and fixing of the optical lens.

[0025] The bottom perimeter of the fixed chamber 11 is fixedly connected with four fixed frames 12 at equal angles. Each of the four fixed frames 12 is fixedly connected to a mounting base 13 at one end. Mounting holes are provided between the upper and lower side walls of the mounting base 13. The thickness detection device of the overall optical lens can be fixedly installed at the corresponding installation position through the mounting holes on the four mounting bases 13 in conjunction with the mounting components.

[0026] The measuring mechanism 2 includes a rotating seat 21 rotatably mounted at the upper opening of the fixed chamber 11. A cross groove 22 is formed between the upper and lower side walls at the center of the rotating seat 21. A handle 26 is fixedly connected to each side of the top of the rotating seat 21. A positioning reference sleeve 23 is slidably connected in the cross groove 22. A scale rod 24 is slidably connected in the positioning reference sleeve 23. Graduation grooves are formed at both the front and rear ends of the outer side wall of the scale rod 24. A grip block 25 is fixedly connected to the top of the scale rod 24. The measuring mechanism 2 adopts a multi-directional adjustable structure design, and the scale rod 24 The positioning reference sleeve 23 is slidably connected to the positioning reference sleeve 23, and can be positioned and raised. The bottom end of its scale rod 24 contacts the lens. At this time, the thickness of the lens can be measured by the scale of the scale rod 24 in conjunction with the positioning reference sleeve 23. Since the positioning reference sleeve 23 is slidably connected to the cross groove 22, and the cross groove 22 is opened on the rotating seat 21, and the rotating seat 21 is rotatably assembled on the top of the fixed chamber 11, the positioning reference sleeve 23 can be adjusted in multiple directions, thereby driving the scale rod 24 to be adjusted in multiple directions, which allows for convenient thickness measurement of the lens at different positions.

[0027] The working principle of this utility model is as follows: An optical lens to be measured can be placed on the bottom wall of the fixed chamber 11. The rotating sleeve 34 can be rotated to pull the connecting column 32 via four elastic metal strips 35, thereby driving the slide blocks 31 in the four slide grooves 14 to move synchronously in opposite directions. That is, the four clamping blocks 36 can clamp the optical lens in the fixed chamber 11 in opposite directions. At this time, the nut of the bolt 33 can be turned to press the rotating sleeve 34, thus completing the clamping and fixing of the optical lens. Its measuring mechanism 2 adopts a multi-directional adjustable structure design, and its scale rod 24 is slidably connected. Within the positioning reference sleeve 23, positioning and lifting can be performed. The bottom end of its scale rod 24 contacts the lens. At this time, the thickness of the lens can be measured by the scale of the scale rod 24 in conjunction with the positioning reference sleeve 23. Since the positioning reference sleeve 23 is slidably connected in the cross groove 22, and the cross groove 22 is opened on the rotating seat 21, and the rotating seat 21 is rotatably mounted on the top of the fixed chamber 11, the positioning reference sleeve 23 can be adjusted in multiple directions, thereby driving the scale rod 24 to be adjusted in multiple directions, enabling convenient thickness measurement of the lens at different positions.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
