Description

Technical Field

[0001] This application relates to the technical field of spectacle lens processing, and in particular to a spectacle lens polishing apparatus. Background Technology

[0002] Eyeglasses are one of the most common items in people's daily lives. From functional glasses such as nearsighted glasses, reading glasses, and sunglasses to ordinary glasses used only for decoration, various styles of glasses are appearing more and more in our lives. During the lens polishing process, white edges often appear on the edges of the lenses, especially the white edges of high myopia lenses. When eyeglass wearers choose small-rimmed or even rimless eyeglass frames, the presence of white edges greatly affects the aesthetics.

[0003] When polishing the white edges of eyeglass lenses, it is usually done manually by holding the lens close to the polishing machine. However, holding the lens requires constantly rotating it to change the polishing position. When the lens is held manually and needs to be rotated constantly, the worker is prone to fatigue, and the range of rotation is difficult to control, which can affect the final polishing effect.

[0004] Therefore, those skilled in the art have provided a spectacle lens polishing apparatus to solve the problems mentioned in the background art. Utility Model Content

[0005] To address the problems mentioned in the background art, this application provides a spectacle lens polishing apparatus.

[0006] The spectacle lens polishing device provided in this application adopts the following technical solution:

[0007] A spectacle lens polishing device includes a worktable, a polishing disc rotatably mounted on the top of the worktable, side supports mounted on both sides of the polishing disc on the worktable, and a clamping assembly mounted between the two side supports.

[0008] The clamping assembly includes two horizontally symmetrically arranged sleeves. A clamping rod is slidably fitted in the sleeves. A rubber clip for clamping the spectacle lens is installed at the end of the clamping rod. A collar is also rotatably fitted on the clamping rod. A V-shaped elastic clamp is installed between the two collars. A rotating component that pushes the clamping rod to rotate is also installed on the elastic clamp.

[0009] Preferably, the rotating assembly includes a motor mount mounted on the side of the elastic clamp, a micro motor mounted in the motor mount, an active bevel gear mounted on the output shaft of the micro motor, and a passive bevel gear meshing with the active bevel gear fitted on the clamping rod near the micro motor.

[0010] Preferably, a stopper is rotatably mounted on the end of the clamping rod extending into the sleeve, and a retraction spring is installed between the stopper and the inner wall of the sleeve.

[0011] Preferably, a fixed shaft is horizontally mounted on the side bracket, and bearing rings are fitted on both the fixed shaft and the end of the sleeve. A connecting plate is installed between the two bearing rings on the same side.

[0012] Preferably, a drive motor is also installed on the worktable. The output shaft of the drive motor and the end of the central shaft of the polishing disc extending into the worktable are both fitted with pulleys, and the same synchronous belt is installed on the two pulleys for transmission.

[0013] A water tank is installed on the top surface of the workbench, and a faucet extending to the top of the polishing disc is installed on the side of the water tank. A knob switch for adjusting the water flow is installed on the faucet.

[0014] In summary, this application includes the following beneficial technical effects:

[0015] 1. In this application, the clamping rod is slidably fitted into the sleeve, and elastic clips are connected to the two collars. When the operator manually squeezes the elastic clips, the two clamping rods can be pushed to clamp and fix the lens. The elastic clips are also equipped with a rotating component that can push the clamping rods to rotate, which can evenly push the lens to rotate during the polishing process with the polishing disc, thereby effectively ensuring the polishing effect of the lens.

[0016] 2. In this application, bearing rings are fitted on both the fixing rod and the sleeve, and a connecting plate is installed between the two bearing rings. After the operator squeezes the elastic clamp to hold the lens, he presses it down, and the sleeve can rotate downward around the fixing axis until the lens contacts the polishing disc for grinding and polishing.

[0023] 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.

[0024] Example 1

[0025] like Figure 1-5As shown, this application discloses a spectacle lens polishing device, including a worktable 1. A polishing disc 2 is rotatably mounted on the top of the worktable 1. Side supports 3 are also mounted on the worktable 1 at positions on both sides of the polishing disc 2. A clamping assembly is installed between the two side supports 3. The clamping assembly includes two horizontally symmetrically arranged sleeves 301. A clamping rod 302 is slidably fitted in the sleeves 301. A rubber clamping plate 303 for clamping spectacle lenses is installed on the end of the clamping rod 302. A collar 304 is also rotatably fitted on the clamping rod 302. A V-shaped elastic clamp 305 is installed between the two collars 304. A fixed shaft 306 is horizontally mounted on the side supports 3. A bearing ring 307 is fitted on the end of both the fixed shaft 306 and the sleeve 301. A connecting plate 308 is installed between the two bearing rings 307 on the same side. In use, pressing the elastic clamp 305 will push the elastic clamp 305. The two clamping rods 302 slide closer together, thereby pushing the rubber clamping plate 303 to clamp the two sides of the lens and keep it fixed. During this process, since the motor base 309 and the micro motor 310 are fixedly installed on the side of the elastic clamp 305, the active bevel gear 311 moves synchronously with the elastic clamp 305, while the passive bevel gear 312 is fitted on the clamping rod 302 and moves synchronously with the clamping rod 302. Therefore, the active bevel gear 311 and the passive bevel gear 312 keep moving synchronously, and the meshing relationship between them remains unchanged and is not affected by the pressing action of the elastic clamp. Furthermore, since the fixed shaft 306 is connected to the bearing ring 307 on the sleeve 301 through the connecting plate 308, when the elastic clamp 305 is pressed down, the sleeve 301 can rotate downward around the fixed shaft 306. When the lens contacts the polishing disc 2, it can be polished.

[0026] like Figure 1 , 2 As shown in Figure 5, the elastic clamp 305 is also equipped with a rotating assembly that drives the clamping rod 302 to rotate. The rotating assembly includes a motor base 309 mounted on the side of the elastic clamp 305, a micro motor 310 mounted in the motor base 309, an active bevel gear 311 mounted on the output shaft of the micro motor 310, and a passive bevel gear 312 meshing with the active bevel gear 311 is also fitted on the clamping rod 302 near the micro motor 310. In order to ensure the free rotation of the clamping rod 302, a stopper is rotatably mounted on the end of the clamping rod 302 that extends into the sleeve 301. A retraction spring 3022 is installed between the stopper 3021 and the inner wall of the sleeve 301. Due to the connection and cooperation of the stopper 3021 and the retraction spring 3022, after the work is completed, the stopper 3021 can pull the clamping rod 302 to retract into the sleeve 301, thereby releasing the lens for easy removal. The clamping rod 302 and the stopper 3021 are rotatably connected. With the cooperation of the active bevel gear 311 and the passive bevel gear 312, the clamping rod 302 can be easily pushed to rotate, thereby facilitating the rotation of the lens during the polishing process and ensuring uniform polishing.

[0027] like Figures 1 to 3 As shown, a drive motor 201 is also installed on the worktable 1. The output shaft of the drive motor 201 and the end of the central shaft of the polishing disc 2 extending into the worktable 1 are both fitted with pulleys 202. The same synchronous belt 203 is installed on the two pulleys 202. When the drive motor 201 is working, it can drive the corresponding pulley 202 to rotate. The two pulleys 202 keep rotating synchronously under the action of the synchronous belt 203, which can drive the polishing disc 2 to rotate, making it convenient to polish the eyeglass lens.

[0028] Example 2

[0029] like Figure 1 As shown, a water tank 101 is further provided on the top surface of the workbench 1. A faucet 102 extending above the polishing disc 2 is installed on the side of the water tank 101. A knob switch 103 for adjusting the water flow is installed on the faucet 102. The faucet 102 extending above the polishing disc 2 can release water droplets onto the lens during the polishing process, washing away the powder and reducing the temperature of the polishing area, thereby ensuring the polishing effect.

[0030] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0031] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0032] The implementation principle of the spectacle lens polishing device in this application embodiment is as follows:

[0033] In use, first start the drive motor 201. With the cooperation of the synchronous belt 203, the two pulleys 202 can rotate synchronously, which in turn drives the polishing disc 2 to rotate. Then, the eyeglass lens can be placed between the two clamping rods 302. Press the elastic clamp 305. The elastic clamp 305 can push the two clamping rods 302 closer and slide, thereby pushing the rubber clamp 303 to clamp the two sides of the eyeglass lens and keep it fixed. Since the fixed shaft 306 is connected to the bearing ring 307 on the sleeve 301 through the connecting plate 308, when the elastic clamp 305 is pressed down, the sleeve 301 can rotate downward around the fixed shaft 306. When the eyeglass lens contacts the polishing disc 2, it can be polished.

[0034] Furthermore, the clamping rod 302 and the cassette 3021 are rotatably connected. With the cooperation of the active bevel gear 311 and the passive bevel gear 312, when the micro motor 310 is started, it can easily push the clamping rod 302 to rotate, thereby facilitating the rotation of the lens during the polishing process and ensuring uniform polishing. The cassette 3021, due to the connection and cooperation of the compression spring 3022, can pull the clamping rod 302 to retract into the sleeve 301 after the work is completed, thereby releasing the lens for easy removal.

[0035] Furthermore, the faucet 102 extending above the polishing disc 2 can release water droplets onto the lens during the polishing process, washing away powder while reducing the temperature of the polishing area, thus ensuring the polishing effect.

[0036] 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.
