Description

Technical Field

[0001] This utility model relates to the technical field of lens testing devices, specifically a portable rapid testing device for the abrasion resistance of lenses. Background Technology

[0002] Eyeglass lenses are transparent or semi-transparent optical elements embedded within eyeglass frames, used to correct vision, protect the eyes, or achieve specific optical functions. Their core function is to improve visual clarity by refracting light and focusing it precisely onto the retina. Eyeglass lenses are an important component of the optical system, designed based on the principles of geometric optics, precisely controlling the refraction, reflection, or scattering of light.

[0003] However, existing technologies for testing lens abrasion resistance rely on manual grinding, which increases the workload for workers and requires a significant amount of time and physical effort. To address this issue, a portable rapid lens abrasion resistance testing device has been developed. Utility Model Content

[0004] The purpose of this utility model is to provide a portable rapid testing device for the abrasion resistance of lenses, in order to solve the problems mentioned in the background art. To achieve the above objective, this utility model provides the following technical solution: a portable rapid testing device for the abrasion resistance of lenses, including a base, a fixing frame at the top of the base, a support at the top of the inner cavity of the fixing frame, a second motor at the right end of the support, the output end of the second motor extending into the inner cavity of the support, a rotating column rotatably connected to the left side of the inner cavity of the support via a bearing, the other end of the rotating column being fixedly connected to the output end of the second motor, a roller fixedly sleeved on the outer wall of the rotating column, a groove circumferentially formed on the outer wall of the roller, the groove being spiral-shaped and connected end to end, two guide rods in the inner cavity of the support, a sliding plate slidably sleeved on the outer wall of the two guide rods, a slider at the top of the sliding plate, the other end of the slider slidably embedded in the inner cavity of the groove, and a polishing brush at the bottom of the sliding plate.

[0005] Preferably, the polishing brush is a nanobrush.

[0006] Preferably, a frame is provided at the top of the base, a first motor is provided at the left end of the frame, the output end of the first motor extends into the inner cavity of the frame, a lead screw is rotatably connected to the right side of the inner cavity of the frame via a bearing, the other end of the lead screw is fixedly connected to the output end of the first motor, movable blocks are screwed to the left and right sides of the outer wall of the lead screw, a cylinder is provided at the top of each of the two movable blocks, a movable plate is provided at the output end of each of the two cylinders, and a fixing groove is provided on the side of each of the two movable plates that are close to each other.

[0007] Preferably, the inner cavity of the fixing groove is adapted to fit the outer wall of the lens.

[0008] Preferably, the threads on the left and right sides of the outer wall of the lead screw are arranged opposite to each other.

[0009] Preferably, a limiting groove is provided at the bottom of the inner cavity of the frame, and two limiting blocks are slidably embedded in the inner cavity of the limiting groove, and the two limiting blocks are respectively fixedly connected to two moving blocks.

[0010] Preferably, the inner cavity of the limiting groove and the outer wall of the limiting block are adapted to each other and are both in the shape of a "T".

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] The first motor drives the lead screw to rotate, which in turn generates a relative thread rotation force on the opposite threads on the left and right sides of the lead screw's outer wall. This causes the two moving blocks to slide simultaneously towards the top center of the base under the limiting action of the limiting groove and the limiting block. This, in turn, causes the two cylinders to drive the two moving plates and the two fixing grooves to slide simultaneously towards the top center of the base. The two fixing grooves clamp and fix the lens, preventing the lens from moving during the polishing process and improving the stability of the device during use. The cylinders allow the moving plates to slide the lens upwards and make close contact with the bristles of the polishing brush.

[0013] The second motor drives the rotating column, roller, and slide to rotate. Since the slide is spiral and connected end to end, when the slide rotates, the slider can drive the slide plate to slide back and forth horizontally under the limiting action of the two guide rods. This causes the slide plate to drive the polishing brush to slide back and forth to polish the lens, thereby realizing the detection of the lens's abrasion resistance. This solves the problem that the existing technology uses manual polishing to test the lens's abrasion resistance, which increases the workload of workers and requires a lot of time and physical strength.

[0020] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1 to 5 This utility model provides a technical solution: a portable lens abrasion resistance rapid testing device, including a base 1, a fixing frame 2 at the top of the base 1, a support 3 at the top of the inner cavity of the fixing frame 2, a second motor 14 at the right end of the support 3, the output end of the second motor 14 extending into the inner cavity of the support 3, a rotating column 15 rotatably connected to the left side of the inner cavity of the support 3 via a bearing, the other end of the rotating column 15 being fixedly connected to the output end of the second motor 14, a roller 16 fixedly sleeved on the outer wall of the rotating column 15, a groove 17 spirally connected to the outer circumference of the roller 16, two guide rods 18 in the inner cavity of the support 3, a sliding plate 19 slidably sleeved on the outer wall of the two guide rods 18, and a top of the sliding plate 19 being provided with... The slider 20 has its other end slidably embedded in the inner cavity of the slide groove 17. The bottom end of the slide plate 19 is equipped with a polishing brush 4. The second motor 14 drives the rotating column 15, the roller 16, and the slide groove 17 to rotate. Since the slide groove 17 is spiral and connected end to end, when the slide groove 17 rotates, the slider 20 can drive the slide plate 19 to slide back and forth horizontally under the limiting action of the two guide rods 18. This causes the slide plate 19 to drive the polishing brush 4 to slide back and forth horizontally to polish the lens, thereby realizing the detection of the lens's abrasion resistance. This solves the problem that the existing technology uses manual polishing to test the lens's abrasion resistance, which increases the workload of workers and requires a lot of time and physical strength.

[0022] In this embodiment, the polishing brush 4 is a nano brush, which has a long service life and low cost.

[0023] In this embodiment, a frame 5 is provided at the top of the base 1, and a first motor 9 is provided at the left end of the frame 5. The output end of the first motor 9 extends into the inner cavity of the frame 5. A lead screw 10 is rotatably connected to the right side of the inner cavity of the frame 5 through a bearing. The other end of the lead screw 10 is fixedly connected to the output end of the first motor 9. Moving blocks 11 are screwed to the left and right sides of the outer wall of the lead screw 10, respectively. A cylinder 6 is provided at the top of each of the two moving blocks 11, and a moving plate 7 is provided at the output end of each of the two cylinders 6. A fixing groove 8 is provided on the side of the two moving plates 7 that are close to each other.

[0024] In this embodiment, the inner cavity of the fixing groove 8 is adapted to the outer wall of the lens, which makes the lens fixing effect more stable.

[0025] In this embodiment, the threads on the left and right sides of the outer wall of the lead screw 10 are arranged opposite to each other, so that when the lead screw 10 rotates, the left and right sides of its outer wall generate relative thread rotational forces, causing the two moving blocks 11 to slide relative to each other at the same time.

[0026] In this embodiment, a limiting groove 12 is provided at the bottom of the inner cavity of the frame 5. Two limiting blocks 13 are slidably embedded in the inner cavity of the limiting groove 12. The two limiting blocks 13 are fixedly connected to two moving blocks 11 respectively. Under the combined action of the limiting groove 12 and the limiting blocks 13, the moving blocks 11 can be prevented from rotating with the lead screw 10 when the lead screw 10 rotates.

[0027] In this embodiment, the inner cavity of the limiting groove 12 and the outer wall of the limiting block 13 are adapted to each other and are both in the shape of a "T". This ensures that one end of the limiting block 13 is always embedded in the inner cavity of the limiting groove 12, thereby improving the stability during use.

[0028] The first motor 9 drives the lead screw 10 to rotate, thereby generating a relative thread rotation force on the opposite threads on the left and right sides of the outer wall of the lead screw 10. Under the limiting action of the limiting groove 12 and the limiting block 13, the two moving blocks 11 slide simultaneously towards the top center of the base 1. This causes the two cylinders 6 to drive the two moving plates 7 and the two fixing grooves 8 to slide simultaneously towards the top center of the base 1. The two fixing grooves 8 clamp and fix the lens, preventing the lens from moving during the polishing process and improving the stability of the device during use. Through the setting of the cylinders 6, the moving plates 7 can drive the lens to slide upward and make close contact with the bristles of the polishing brush 4.

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.
