[0017] The present invention is described in detail with reference to the accompanying drawings in the embodiments of the present invention.

[0018] See also Figure 1-5 ,

[0019] An optical lens processing device includes a collecting tube 101, in which a processing table 102 with an internal hollow structure is rotatably connected via a bearing. The processing table 102 is conical, and a suction cup 103 is fixedly connected to the upper end of the processing table 102 via bolts. The suction cup 103 is connected to the inside of the processing table 102. A filter cover 104 is sleeved on the processing table 102, and a plurality of arc-shaped ridges 105 are integrally formed in the filter cover 104. A grinding mechanism is provided at the upper end of the collecting tube 101.

[0020] When using the processing device, the staff first places the lens to be polished on the suction cup 103, controls the negative pressure inside the processing table 102 to make the suction cup 103 adsorb and fix the lens, and at the same time controls the processing table 102 to rotate, and uses the polishing mechanism to polish the edge of the lens.

[0021] Since dust is generated when the lens is polished, the staff puts the filter cover 104 on the processing table 102 so that the filter cover 104 can rotate with the processing table 102. By controlling the negative pressure inside the collecting tube 101, the airflow enters the collecting tube 101 from above the collecting tube 101 and through the filter cover 104, so that the dust generated by polishing can move downward with the airflow and finally fall on the filter cover 104. The filter cover 104 plays a role in collecting dust.

[0022] Since the air permeability of the filter cover 104 will be affected when the surface is covered with dust, the surface of the multiple arc-shaped ridges 105 in the filter cover 104 is arc-shaped, and the dust will slide down and accumulate after accumulation, thereby ensuring the air permeability of the filter cover 104 and eliminating the need to frequently clean the filter cover 104.

[0023] See also Figure 3 ,

[0024] The grinding mechanism includes a hydraulic rod 501 , the movable end of the hydraulic rod 501 is fixedly connected to a telescopic frame 502 by bolts, a first motor 504 is fixedly connected to the telescopic frame 502 by bolts, and a grinding head 503 is fixedly connected to the output shaft of the first motor 504 .

[0025] The movable end of the hydraulic rod 501 is controlled to extend to drive the grinding head 503 to approach the lens, and the first motor 504 drives the grinding head 503 to rotate to grind the lens.

[0026] See also Figure 4 ,

[0027] The second motor 201 is fixedly connected to the inner wall of the collecting barrel 101 by bolts, and the output shaft of the second motor 201 and the processing table 102 are fixedly connected with a gear 202, and the two gears 202 are meshed for transmission.

[0028] The second motor 201 drives the two gears 202 to mesh and transmit, thereby driving the processing table 102 to rotate, thereby achieving the function of fully polishing the circular lens.

[0029] See also Figure 5-6 ,

[0030] The lower end of the collecting tube 101 is fixedly connected to a shell 301, an impeller 305 is rotatably connected inside the shell 301, a connecting pipe 303 is fixedly connected to the upper end of the shell 301, the connecting pipe 303 is rotatably connected to the processing table 102, an exhaust port 304 is opened on the shell 301, and a plurality of air inlet grooves 302 are opened on the upper part of the shell 301.

[0031] By controlling the rotation of the impeller 305, the air inside the shell 301 is extracted through the exhaust port 304, so that negative pressure is generated in the shell 301. At this time, the air enters the shell 301 through the connecting pipe 303 and the multiple air inlet grooves 302 at the same time, thereby being able to simultaneously achieve the functions of sucking the lens and collecting dust, without the need to control the two separately, reducing the operation links and improving the continuity of the processing process.

[0032] See also Figure 7 ,

[0033] The upper end of the collecting cylinder 101 is fixedly connected to a liquid storage cylinder 405 by bolts, a sliding plug 404 is slidably connected inside the liquid storage cylinder 405, a nozzle 407 and a liquid inlet pipe 406 are welded to the liquid storage cylinder 405, and a one-way valve is installed in the nozzle 407 and the liquid inlet pipe 406.

[0034] The liquid storage cylinder 405 is used to hold water. When the sliding plug 404 slides into the liquid storage cylinder 405, the one-way valve on the nozzle 407 opens, and the one-way valve in the liquid inlet pipe 406 closes. At this time, water is sprayed out through the nozzle 407 in the form of water mist, thereby playing a role in dust reduction. When the sliding plug 404 slides outward, the one-way valve on the nozzle 407 closes, the one-way valve in the liquid inlet pipe 406 opens, and the liquid inlet pipe 406 is connected to a container filled with water, thereby realizing the function of automatic water replenishment.

[0037] By controlling the rotation of the eccentric wheel 401, the connecting rod 402 and the push rod 403 cooperate to drive the sliding plug 404 to slide back and forth, thereby realizing the function of spraying water to reduce dust.

[0038] See also Figure 2 ,

[0039] The housing 301 is fixedly connected with a third motor 601 by means of bolts. The output shaft of the third motor 601 and the eccentric wheel 401 are both fixedly connected with pulleys 602 . The two pulleys 602 are connected by means of a synchronous belt.

[0040] When the impeller 305 rotates to absorb dust, the two pulleys 602 cooperate with the synchronous belt to drive the eccentric wheel 401 to rotate, thereby achieving the function of spraying water to reduce dust, thereby making the overall process more consistent.
