Fixedly connected with support 5 on the workstation 1, one side fixedly connected with connecting rod 6 of mill 2 is kept away from to clamp plate 4, and one side fixedly connected with connecting block 7 of clamp plate 4 is kept away from to connecting rod 6, and connecting block 7 sets up along clamp plate 4's radial. Two sliding grooves 8 are formed in the support 5 in the vertical direction, and two ends of the connecting block 7 are in sliding fit with the two sliding grooves 8 respectively.

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.

Referring to fig. 2 and 3, a rubber pad 9 is fixedly connected to one side of the pressing plate 4 facing the grinding disc 2, and a baffle ring 10 is fixedly connected to one side of the pressing plate 4 facing the grinding disc 2 along the edge of the rubber pad 9. In operation, an operator places the lens on the inner side of the baffle ring 10, and the side of the lens, which is far away from the grinding disc 2, is abutted against the rubber pad 9.

After entering the annular dust suction pipe 12, the debris is blocked by the arc-shaped rubber plate 17 and adheres to the arc-shaped rubber plate 17. After the arc-shaped rubber plate 17 is adhered with the chips, the operator pulls the baffle plate 19 to take the arc-shaped rubber plate 17 out of the arc-shaped slot 16 and replace the arc-shaped rubber plate 17 with a new one, so that the chips can be continuously collected. The baffle 19 limits the arc-shaped rubber plate 17, so that the position of the arc-shaped rubber plate 17 is kept fixed. Debris that bypasses the curved rubber plate 17 is collected at the air inlet 28 of the suction fan 11 under the suction of the suction fan 11, and the filter screen 13 blocks the debris, thereby reducing the possibility that the debris enters the suction fan 11 and affects the normal operation of the suction fan 11.

Referring to fig. 5 and 6, a filter plate 22 is provided in the water tank 20, the filter plate 22 is perpendicular to the bottom wall of the water tank 20, the height of the filter plate 22 is the same as the height of the inner wall of the water tank 20, and the filter plate 22 separates the interior of the water tank 20 into two chambers 29. A collecting box 23 is arranged in a cavity 29 of the filter plate 22, a notch 24 is arranged on the top wall of the water tank 20, and the notch 24 corresponds to the collecting box 23 up and down in position and is in insertion fit. 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.
