Referring to fig. 2, in operation, an operator pulls the connecting block 7, and the connecting block 7 drives the pressing plate 4 through the connecting rod 6, so that the pressing plate 4 is far away from the grinding disc 2. Then, the operator places the lens on the grinding disc 2 and puts down the pressing plate 4 until the pressing plate 4 is abutted against the side of the lens departing from the grinding disc 2 by the dead weight. Then, the motor 3 drives the grinding disc 2 to rotate, the lens is kept fixed at the abutting position of the pressing plate 4, and the rough surface 27 of the grinding disc 2 grinds the lens by means of friction force.

The water tank 20 is fixedly connected with a water pump 21, a water inlet port of the water pump 21 is communicated with a cavity 29 in the water tank 20, a water outlet port of the water pump 21 is welded with a drain pipe 25, and one end, far away from the water pump 21, of the drain pipe 25 extends to the position above the grinding disc 2. The worktable 1 is provided with a water tank 26, the cross section of the water tank 26 is annular and is coaxial with the grinding disc 2, and the grinding disc 2 is provided with a conical surface 15 along the periphery. A receiving pipe 18 is fixedly connected to the bottom of the working platform 1, one end of the receiving pipe 18 is communicated with the water tank 26, and the other end is communicated with another cavity 29 in the water tank 20.
Referring to fig. 5 and 6, at the end of the grinding, the operator needs to polish the lens. During polishing, the exhaust fan 11 stops running, the water pump 21 pumps polishing liquid in the water tank 20 into the water drainage pipe 25, the polishing liquid flows onto the grinding disc 2 through the water drainage pipe 25 and soaks the grinding disc 2 and the surface of the lens, and the grinding disc 2 polishes the lens. The polishing liquid carries the debris to flow towards the edge of the grinding disc 2 under the action of centrifugal force, and the conical surface 15 at the edge of the grinding disc 2 can accelerate the flow speed of the polishing liquid. The slurry leaves the conical surface 15 and flows into the water tank 26 and into the water tank 20 through the receiving pipe 18. The polishing solution flowing into the water tank 20 is pumped by the water pump 21 and re-enters the drain pipe 25, so that the polishing solution can be recycled. The debris carried in the polishing liquid is blocked by the filter sheet 22 and falls onto the collection box 23. When the collection box 23 is filled with the debris, the operator takes out the collection box 23 and the filter plate 22 along the notch 24 and cleans them, so that the collection box 23 continuously collects the debris in the polishing liquid.
The implementation principle of the optical lens grinding device in the embodiment of the application is as follows: during operation, an operator places the lens on the grinding disc 2 and moves the pressing plate 4, so that the pressing plate 4 fixes the position of the lens through the rubber pad 9 of the baffle ring 10. Then, the motor 3 drives the grinding disc 2 to rotate, and the grinding disc 2 grinds the lens. The exhaust fan 11 extracts the debris generated in the grinding process through the annular dust suction pipe 12, and the arc-shaped rubber plate 17 collects the debris. The provision of the annular suction pipe 12 reduces the possibility that debris remote from the suction fan 11 of the suction fan 11 is difficult to recover because the direction of extraction by the suction fan 11 is fixed. In the later stage of grinding, when the grinding disc 2 polishes the lens, the exhaust fan 11 stops running, and the water pump 21 conveys the polishing liquid in the water tank 20 to the grinding disc 2. After the polishing fluid soaks the disk 2 and the lens, it flows through the tapered surface 15 into the water trough 26 and then back into the water tank 20 through the receiving tube 18, carrying the debris. The filter plate 22 blocks debris carried in the slurry, and the debris is deposited in the collection box 23 after being blocked. When the collection box 23 is full of debris, the operator takes out the collection box 23 to clean the debris.
