Description

Technical Field

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

[0002] An optical glass lens thickness measuring device is an instrument used to measure the thickness of lenses. It can quickly acquire thickness data at multiple points, such as the center and edges of the lens, to verify whether the thickness meets requirements. This device is widely used in optical manufacturing, spectacle lens processing, and scientific research, and can significantly improve the efficiency of quality control for optical glass lens products.

[0003] An optical glass lens thickness detection device disclosed in Chinese Patent Publication No. CN 220454462 U can detect the thickness of glass lenses by using a positioning sleeve, a movable rod, a base plate, a push block, and a scale. By setting up a rotary motor, a rotating shaft, and a turntable, the position of the glass lens can be adjusted, which is convenient for multi-point detection of the glass lens. However, the detection device has certain limitations. Since the optical glass lens is arc-shaped and the thickness may vary at different locations, the curvature of the optical glass lens can cause deviations in the measurement results during the detection process, thus affecting the overall accuracy of the detection device and the subsequent processing quality of the optical glass lens.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-5 This utility model provides an optical glass lens thickness detection device, including a detection platform 1 and a fixed frame 4. A support rod 101 is fixedly connected to the center of the upper surface of the detection platform 1. A fixed arm 2 is fixedly connected to the left side of the upper surface of the detection platform 1. A detection rod 7 is slidably connected to the center of the inner surface of the fixed arm 2. A scale mark 701 is provided at the front end of the detection rod 7. A pressing mechanism 8 is provided at the center of the outer surface of the detection rod 7. A handle 402 is fixedly connected to the center of the right side of the fixed frame 4. A limit mechanism 5 is provided inside the fixed frame 4. A lens body 6 is provided inside the fixed frame 4. An adjustment mechanism 3 is also included. The adjustment mechanism 3 is used to adjust the position of the fixed frame 4 on the right side of the fixed arm 2. The support rod 101 can cooperate with the detection rod 7 to perform optical glass lens thickness detection.

[0021] Both the contact surfaces of the support rod 101 and the detection rod 7 are equipped with ball bearings, which are used to reduce the friction generated when the support rod 101 and the detection rod 7 come into contact with the lens body 6.

[0022] The adjustment mechanism 3 includes a movable groove 201 located at the center of the left side inside the fixed arm 2. A first spring 202 is fixedly connected to the bottom end of the movable groove 201, and a movable block 203 is fixedly connected to the top end of the first spring 202. A telescopic rod 301 is fixedly connected to the right side of the movable block 203, and a limit slider 302 is fixedly connected to the right side of the telescopic rod 301. A slide rod 401 is fixedly connected to the inside of the left side of the fixed frame 4, and the limit slider 302 is slidably connected to the outside of the slide rod 401. When the support rod 101 contacts the lower surface of the lens body 6 at different positions, the movable block 203 can be driven to slide in the movable groove 201 through the fixed frame 4 and the telescopic rod 301, and the first spring 202 can be squeezed or stretched to ensure that the support rod 101 is in contact with the lower surface of the lens body 6. At the same time, the telescopic rod 301 can cause the handle 402 to drive the fixed frame 4 to move laterally, and the limit slider 302 on one side of the telescopic rod 301 slides in the slide rod 401 on the fixed frame 4, thereby allowing the fixed frame 4 to move longitudinally as a whole.

[0023] The limiting mechanism 5 includes a support ring 403 fixed to the bottom of the fixed frame 4. The support ring 403 is used to support the lens body 6. An inflation port 501 is fixed to the left side of the upper surface of the fixed frame 4. An air supply pipe 502 is provided at the bottom of the inflation port 501. An airbag 503 is fixed to the center of the fixed frame 4. The center of the right side of the airbag 503 is connected to the air supply pipe 502. An external inflator can inflate the airbag 503 through the inflation port 501. When the airbag 503 is inflated, it can work with the support ring 403 to stably clamp and limit the lens body 6.

[0024] The pressing mechanism 8 includes a connecting plate 801 fixedly attached to the outer center of the detection rod 7. The connecting plate 801 slides inside the fixed arm 2. The left and right sides of the upper surface of the connecting plate 801 are fixedly attached to the second springs 802. When the lower surface of the detection rod 7 contacts the lens body 6, the second springs 802 can be squeezed by the connecting plate 801. Due to the reaction force of the second springs 802 being squeezed, the detection rod 7 can be pushed to adhere to the upper surface of the lens body 6 by the connecting plate 801.

[0025] The elastic force of the second spring 802 is greater than that of the first spring 202. In addition, all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0026] In this embodiment, the lens body 6 is placed on the support ring 403 inside the fixed frame 4. The air inlet 501 is then opened, allowing an external inflator to inflate the airbag 503. The inflated airbag 503, in conjunction with the support ring 403, stably limits the position of the lens body 6. The support rod 101 stably supports the lower surface of the lens body 6. The detection rod 7 contacts the upper surface of the lens body 6, and the connecting plate 801 compresses the second spring 802. Due to the reaction force of the compressed second spring 802, the connecting plate 801 pushes the detection rod 7 to adhere to the upper surface of the lens body 6. By observing the thickness of the scale markings 701 on the detection rod 7, the thickness of the lens body 6 can be measured. The fixed frame 4 is moved by pulling the handle 402, allowing the fixed frame 4 to adjust the contact position of the lens body 6 with the support rod 101 and the detection rod 7, thereby measuring the thickness of the lens body 6 at various locations.

[0027] The foregoing has shown and described 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 preferred examples and are not intended to limit the 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 claimed utility model.
