[0038] An ejection mechanism 5 is disposed at the bottom of the operating table 1 and is used to remove the optical components after the polishing process is completed;

[0039] The flushing mechanism 4 is provided with two groups, and the two groups of flushing components are symmetrically distributed on the left and right sides of the top of the operating table 1, and are used for flushing the optical parts when the optical parts are replaced with different precision grinding heads 305.

[0040] In a further embodiment, referring to Figure 3-Figure 4The polishing assembly includes a frame 306, which is fixedly connected to the top of the operating table 1. An arc plate 304 is arranged on the inner side of the frame 306. Three arc-shaped stepper motors 303 are arranged on the top of the arc plate 304. The three stepper motors 303 are fixedly connected to polishing heads 305 with different degrees of roughness through output shafts. The stepper motors 303 can drive the corresponding polishing heads 305 to rotate through the output shaft to polish the outer side of the optical component. The frame 306 is fixedly connected with a useful The cylinder 301 is used to push the arc plate 304 to move. The outside of the stepper motor 303 is fixedly connected to a motor frame 302. The motor frame 302 is fixedly connected to the top of the arc plate 304. The rear side of the arc plate 304 extends into the inside of the frame 306. The arc plate 304 is fixedly connected to the telescopic end of the cylinder 301. The cylinder 301 is used to push the arc plate 304 to move downward, so that the optical components can be polished by the polishing head 305. The height of the arc plate 304 can be adjusted according to the polishing requirements.

[0041] Specifically, the roughness of the three grinding heads 305 increases from left to right. The leftmost grinding head 305 is set as a fine grinding head 305 , the middle grinding head 305 is set as a medium grinding head 305 , and the rightmost grinding head 305 is a coarse grinding head 305 .

[0042] In addition, a slider is fixedly connected to the outer side of the arc plate 304, a sliding groove is provided on the inner side of the frame 306, and the slider is slidably connected to the inner side of the sliding groove.

[0043] In this embodiment, the cylinder 301 pushes the arc plate 304 to move downward, so that the optical components thereunder are polished with different coarseness and precision by three polishing heads 305 of different coarseness and precision, thereby improving the polishing efficiency and the polishing precision by polishing with different coarseness and precision.

[0044] In a further embodiment, referring to Figure 1-Figure 3 and Figure 7 The feeding assembly includes a storage plate 310, which is arranged on the top of the operating table 1. An arc-shaped placement groove 309 is opened on the top of the storage plate 310. A servo motor 308 is fixedly connected to the bottom of the operating table 1. The servo motor 308 is fixedly connected to a rotating shaft through an output shaft. The top of the rotating shaft passes through the operating table 1 and is movably connected to the operating table 1 through a bearing. The rotating shaft is installed at the bottom of the storage plate 310. An arc pad 307 is fixedly connected to the top of the operating table 1. The arc pad 307 can support the optical components from the bottom of the storage plate 310 when they are polished to ensure stability during polishing. The arc pad 307 is arranged below the arc plate 304.

[0045] Specifically, the shape of the placement groove 309 can be adjusted according to the shape of the optical component, and optical components of different shapes can be polished by replacing different placement plates 310 .

[0046] In this embodiment, the servo motor 308 can drive the placement plate 310 on which the optical components are placed to rotate, thereby rotating the optical components that need to be polished to the bottom of different polishing heads 305, and performing polishing from coarse to fine in sequence, thereby improving the polishing accuracy and effect. While the optical components are being polished, the polished optical components are unloaded and new optical components that need to be polished are loaded.

[0047] In a further embodiment, referring to Figure 2 The flushing mechanism 4 includes a mounting rod 402, two mounting rods 402 are symmetrically fixedly connected to the top of the operating table 1, a cleaning nozzle 403 is arranged on the top of the mounting plate, and an arc groove 401 for guiding cleaning water is opened on the top of the operating table 1.

[0048] Specifically, a U-shaped block is fixedly connected to the top of the mounting rod 402, the cleaning nozzle 403 is movably connected to the inner side of the U-shaped block, and the rear side of the cleaning nozzle 403 is fixedly connected to a water inlet pipe for water to enter.

[0049] In this embodiment, the cleaning nozzle 403 is located between two adjacent grinding heads 305. When the grinding head 305 of an optical component is replaced, the newly polished optical component is rinsed, and impurities generated by grinding are removed while cooling, making it convenient to change the grinding accuracy of different grinding heads 305.

[0050] In a further embodiment, referring to Figure 2-Figure 3 and Figure 6 The ejection mechanism 5 includes a driving motor 502, which is arranged at the bottom of the operating table 1. The driving motor 502 is fixedly connected to the cam 503 through the output shaft. The top of the operating table 1 is fixedly connected to a tension spring, and the bottom of the tension spring is fixedly connected to a connecting strip 506. The top of the connecting strip 506 is fixedly connected to a push rod 504. An ejection hole 508 is opened at the bottom of the placement groove 309. The top of the push rod 504 passes through the operating table 1 and is slidably connected to the operating table 1. The top of the push rod 504 is fixedly connected to a rubber pad 507. The rubber pad 507 is used to protect the optical component when the push rod 504 ejects it to avoid damage. A fixing plate 501 is fixedly connected to the outside of the driving motor 502, and the fixing plate 501 is fixedly connected to the bottom of the operating table 1.

[0051] Specifically, the push rod 504 is curved in shape. When the second optical component is being polished under the fine polishing head 305 , the first placement groove 309 is located above the push rod 504 . The push rod 504 moves upward to push the optical component out of the placement groove 309 through the rubber block.

[0052] In this embodiment, after the first optical component is polished by the fine polishing head 305 and moved out from under the fine polishing head 305, the driving motor 502 drives the push rod 504 to move upward through the cam 503, and pushes the polished optical component out of the placement groove 309 to facilitate unloading.

[0053] The working principle of the present invention is as follows:

[0054] When polishing an optical component, the optical component to be polished is placed in the placement slot 309. After the optical component is placed, the servo motor 308 is started. The servo motor 308 drives the placement plate 310 to rotate through the output shaft and the rotating rod until the optical component on the far right moves to below the polishing head 305 on the far right and stops.

[0055] The cylinder 301 is started to push the arc plate 304 downward, and the arc plate 304 moves downward to mobilize the grinding head 305 and the stepper motor 303 to move downward until the bottom of the grinding head 305 contacts the outer side of the optical component and stops. At this time, the stepper motor 303 is started, and the outer side of the optical component is preliminarily ground by the rough grinding head 305;

[0056] After the rough grinding head 305 finishes grinding the first optical component, the servo motor 308 is started, and the servo motor 308 drives the storage plate 310 to rotate again until the first optical component is located below the middle grinding head 305. At this time, the middle grinding head 305 further grinds the first optical component, and the rough grinding head 305 performs rough grinding on the second optical component.

[0057] When the optical component is replaced with a grinding head 305 of different coarseness, the cleaning nozzle 403 rinses the surface of the optical component, and the rinsed water carries impurities and is discharged from the arc groove 401 to the operating table 1;

[0058] Referring to the above-mentioned polishing method, after the first optical component passes through the fine polishing head 305, the optical component can be removed from the placement slot 309 and a new optical component to be polished can be placed therein to polish the next batch of optical components.

[0059] When the first optical component is taken out from the placement groove 309, the driving motor 502 drives the cam 503 to rotate, and the cam 503 pushes the connecting strip 506 and the push rod to move upward, and the optical component in the placement groove 309 is ejected to achieve the purpose of unloading and complete the polishing of the optical component.

[0060] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
