The middle of the front of the inner side of the rotating frame 2 is rotatably connected to the upper end of the outer surface of the mounting column 1. It also includes a microcontroller 7. The microcontroller 7 is located on the right side of the front end of the upper surface of the base 1.

The mounting plate 31 is rotatably connected to the lower end of the outer surface of the rotating frame 2. The mounting grooves 32 are evenly distributed on the upper end of the mounting plate 31, and each mounting groove 32 has a silicone ring on its inner wall to provide a buffering effect for the optical lens. The limiting bolts 33 are threadedly connected to the lower end of the interior of the rotating frame 2, and the upper end of the limiting bolts 33 is in contact with the lower end of the mounting plate 31. Different sizes of mounting plates 31 can be replaced by removing and installing the limiting bolts 33 to facilitate the placement of the optical lens. The adjusting components 34 are located in the middle of the rear side of the interior of the rotating frame 2. The adjusting components 34 include a lead screw 341, a pressure plate 342, and a knob 343. The lead screw 341 is rotatably connected to the interior of the rotating frame 2. At the rear center of the base 1, pressure plate 342 is slidably connected to the inner rear center of the rotating frame 2. Pressure plate 342 is vertically adjacent to mounting plate 31. Knob 343 is located at the upper end of lead screw 341 to facilitate applying pressure to the optical lens. Polishing assembly 35 is located at the upper rear side of the base 1. Polishing assembly 35 includes polishing disc 351, gear 352, and pulley 353. Polishing disc 351 is rotatably connected to the upper center of the base 1. Mounting post 2 is located at the upper center of the base 1. The inner center of polishing disc 351 is rotatably connected to the upper surface of the outer surface of mounting post 2. Felt layer is provided at the upper end of polishing disc 351 and the lower end of pressure plate 342. The protrusions on the surface of the optical lens are removed by cutting the felt layer and plastic deformation of the optical lens surface to achieve a smooth surface effect. Gear 352 is rotatably connected to the middle of the rear side of the base 1. The outer edge of the mounting plate 31 has evenly distributed teeth. Gear 352 and the teeth form an integral meshing connection. Pulleys 353 are fixedly fitted onto the lower ends of the outer surfaces of both the polishing disc 351 and the gear 352. The diameter of the front pulley 353 is larger than that of the rear pulley 353. The two pulleys 353 are connected by a belt drive, providing a foundation and stable transmission for the polishing of the optical lens. The polishing assembly 35 also includes a motor 354, which is located in the middle of the lower rear side of the base 1. The input end of the motor 354 is electrically connected to the output end of the microcontroller 7. The upper end of the output shaft of the motor 354 is fixedly connected to the lower end of the gear 352, providing stable drive for the polishing of the optical lens. The system includes a limiting knob 4 and a handle 5. The limiting knob 4 is threadedly connected to the middle of the front end of the rotating frame 2. The inner end of the limiting knob 4 is fitted to the upper end of the outer surface of the base 1. A limiting hole is opened on the front side of the middle of the outer surface of the mounting column 1. The outer surface of the inner end of the limiting knob 4 is threadedly connected to the inner wall of the limiting hole. The handle 5 is located in the middle of the front end of the rotating frame 2 to facilitate the deflection of the mounting plate 31. The system also includes a feeding groove 6, which is located on the upper right side of the base 1. The feeding groove 6 is fitted to the mounting plate 31. The bottom wall of the feeding groove 6 is lower than the lower end of the mounting plate 31 to facilitate the feeding of optical lenses. A polishing mechanism 3 is provided, which can polish multiple optical lenses simultaneously. During polishing, the optical lenses and the polishing disc 351 always move in opposite directions.This improves the utilization rate of polishing powder and polishing disc 351, thereby increasing the polishing efficiency of optical lenses.

[0024] The working principle of the polishing device for optical lens processing provided by this utility model is as follows: When polishing optical lenses, polishing powder is first sprinkled on the surface of the polishing disc 351. Then, the optical lenses are placed into the mounting groove 32 in sequence, with the lower end of the optical lens contacting the surface of the polishing disc 351. Then, the knob 343 is rotated to drive the lead screw 341 to rotate, and the pressure plate 342 also moves down until the lower end of the pressure plate 342 contacts the upper end of the optical lens and applies appropriate pressure to the optical lens. The microcontroller 7 controls the motor 354 to operate, and the output shaft of the motor 354 drives the gear 352 to rotate. The mounting plate 31 also reverses due to the meshing action. At the same time, the rear pulley 353 also rotates with the rotation of the gear 352. Because the diameter of the front pulley 353 is larger than the diameter of the rear pulley 353, the two pulleys 353 can form a transmission effect. Two pulleys 353 are connected by belt drive, so the front pulley 353 also rotates, driving the polishing disc 351 to rotate. At this time, the mounting plate 31 reverses, and the optical lens moves with the rotation of the mounting plate 31. The polishing disc 351 rotates forward, and the optical lens and the polishing disc 351 always move in opposite directions, avoiding the optical lens from always being polished in the same position. This maximizes the utilization rate of polishing powder and the polishing disc 351 itself, thereby improving the polishing efficiency of the optical lens. After the polishing work is completed, the limit knob 4 is reversed so that the inner end of the limit knob 4 is completely removed from the limit hole. Then, the handle 5 is pulled to the right, and the rotating frame 2 deflects to the left. The mounting plate 31 also deflects to the left until the mounting plate 31 moves above the feeding groove 6. The optical lens inside the mounting groove 32 falls onto the surface of the feeding groove 6 under the action of gravity, completing the polishing work.

[0025] It is worth noting that the microcontroller 7 disclosed in the above embodiments is an S7-200 microcontroller, and the motor 354 is a YL100L-4 motor. The microcontroller 7 controls the operation of the motor 354 using methods commonly used in the prior art.
