During light polishing, the motor 122 is used to rotate the limiting housing 123 longitudinally to change the contact angle between the inner wall of the arc-shaped polishing disk 129 and the surface of the optical mirror, and then the edges of the optical mirror are polished. The rectangular housing 132 is rotated laterally by the docking rod 131 to rotate the optical mirror to the other side in an angle and direction, and the angle between the arc-shaped polishing disk 129 and the optical mirror is changed. When the angle is changed laterally and longitudinally for polishing, the corners of the optical mirror are effectively polished. When one side of the optical mirror is polished, the docking rod 131 is used to rotate the rectangular housing 132, and the rectangular housing 132 is turned up to expose the unpolished side of the optical mirror, and then the other side of the optical mirror is polished by the arc-shaped polishing disk 129.

[0049] When the rectangular shell 132, closing cover 136 and snap-on protrusion 137 provided by the present invention are in use, when the closing cover 136 is snapped onto the top surface of the rectangular shell 132, the snap-on protrusion 137 is snapped onto the inner wall surface of the snap-on groove 135, and then the rectangular shell 132 and the snap-on protrusion 137 are used to wrap and fix the optical mirror, so that the optical mirror will not fall off from the inside of the rectangular shell 132 when the rectangular shell 132 rotates.

[0050] Furthermore, if Figure 2 - Figure 3 and Figure 7 - Fig. 9 As shown, a support rod 121 is fixedly connected to one side surface of the swing arm 12 and located on both side edge positions of the motor 2 122, a pad 1210 is fixedly connected to the other end of the support rod 121, the number of motors 122 is arranged in two groups, the position of another group of motors 122 is arranged at the center position of one side of the pad 1210, and the output end of another motor 122 is fixedly connected to the surface of the limiting sleeve 123, a polishing liquid tank 126 is fixedly installed on the top surface of the support arm plate 125 and located in the middle position, four groups of liquid guide tubes 127 are fixedly connected to the output end of the polishing liquid tank 126, a polishing liquid penetration circle 124 movably overlapped on the top edge position of the arc-shaped polishing disk 129 is fixedly connected to the inner wall surface of the limiting sleeve 123, and the other ends of the four groups of liquid guide tubes 127 are fixedly connected to the top surface of the polishing liquid penetration circle 124.

[0052] Furthermore, if Figure 2 - Figure 5 As shown, a water tank 111 is provided at the inner bottom of the polishing table 11, a fine filter cloth 113 is fixedly connected to the inner middle position of the polishing table 11, a lap strip 114 is provided at the top edge position of one side of the polishing table 11, and circulating air ducts 112 are symmetrically fixedly installed on the two side surfaces of the polishing table 11, and the two ends of the circulating air duct 112 extend to the inside of the water tank 111 and the top inner wall of the polishing table 11 respectively, a limiting ring 115 is symmetrically and movably sleeved on the inner wall surface of one side of the polishing table 11 and the docking rod 131, and a motor 116 is provided on the other side surface of the polishing table 11 and at the edge position of the docking rod 131.

[0053] The optical mirror provided by the present invention absorbs gas on the top surface of the fine filter cloth 113 while polishing and grinding, and the gas on the top position of the polishing table 11 is quickly absorbed, and a low-pressure environment is formed on the top of the polishing table 11. The gas around the low pressure will flow toward the input end of the circulating air duct 112, thereby driving the flow of air. When the air flows, it will absorb and flow the dust polished around the optical mirror, and guide it into the inside of the circulating air duct 112, and then infuse it into the inside of the water tank 111. As the air flows, the dust When the gas is continuously infused into the water tank 111, the air pressure inside the water tank 111 will increase greatly, and the discharged gas will mix with the water source inside the water tank 111, and then mix the dust in the air and degrade it, and the excess gas will gradually spread upward. When the gas passes through the fine filter cloth 113, the fine filter cloth 113 will filter out the dust remaining in the gas, and the gas passing through the fine filter cloth 113 will form an upward airflow, and the upward airflow will push some uncleaned dust that has fallen into the low-pressure environment on the top of the polishing table 11 to absorb and clean the dust. Example 2

[0054] like Figure 1 - Figure 7 As shown, the present invention also provides a double-sided polishing process, comprising the following steps:

[0055] S1, positioning and clamping the surface of the lens;

[0056] S2. When polishing the lens, swing it longitudinally and transversely to adjust the polishing angle of the lens;

[0057] S3, applying polishing liquid to the polished lens surface to increase the polishing degree of the lens;

[0058] S4. When polishing the lens, use a dust suction device to absorb the dust debris on the surface of the lens, and then absorb and purify the dust with clean water.

[0059] The working principle of the auxiliary loading and unloading device is described in detail below. The optical mirror is clamped onto the inner wall of the rectangular shell 132, and the upper closing cover 136 is closed. The triangular elastic soft block 134 on the inner wall of the rectangular shell 132 and the closing cover 136 is used to squeeze the edge position of the optical mirror to limit its position. The conical overlapping groove 133 on the inner wall of the closing cover 136 is used to raise and support the optical mirror while reducing the contact area and range with the corner position of the optical mirror, leaving a space for grinding and polishing at the corner position of the optical mirror. The swing arm 12 is twisted to make one end of the arc-shaped polishing disk 129 pass through the surface of the closing cover 136, and the arc-shaped polishing disk 129 is rotated by the motor 3 128, so that the arc-shaped polishing disk 129 polishes the optical mirror on the inner wall of the closing cover 136. , and at the same time cooperate with the motor 2 122 to rotate the limit housing 123 longitudinally to change the contact angle between the inner wall surface of the arc-shaped polishing disk 129 and the surface of the optical mirror, and then polish and grind the edges of the optical mirror, and then rotate the rectangular housing 132 horizontally through the docking rod 131 to rotate the optical mirror to the other side angle and direction, change the angle between the arc-shaped polishing disk 129 and the optical mirror, and when the angle is changed horizontally and vertically for polishing, the four peripheral corners of the optical mirror are effectively polished. When one side of the optical mirror is polished, the docking rod 131 is used to rotate the rectangular housing 132, and the rectangular housing 132 is turned up to expose the unpolished side of the optical mirror, and then the arc-shaped polishing disk 129 is used to polish and grind the other side of the optical mirror;

[0060] While the optical mirror is being polished, the circulating air duct 112 absorbs gas from the top surface of the fine filter cloth 113. The gas on the top of the polishing table 11 is quickly absorbed, forming a low-pressure environment on the top of the polishing table 11. The gas around the low pressure will flow toward the input end of the circulating air duct 112, thereby driving the flow of air. When the air flows, it will absorb and flow the dust polished around the optical mirror, guide it into the inside of the circulating air duct 112, and then infuse it into the inside of the water tank 111. As the air is continuously infused, When entering the water tank 111, the air pressure inside the water tank 111 will increase greatly, and the discharged gas will mix with the water source inside the water tank 111, and then mix the dust in the air and degrade it, and the excess gas will gradually spread upwards. When the gas passes through the fine filter cloth 113, the fine filter cloth 113 will filter out the dust remaining in the gas, and the gas passing through the fine filter cloth 113 will form an upward airflow. The rising airflow will push some uncleaned dust that has fallen into the low-pressure environment on the top of the polishing table 11 to absorb and clean the dust.

[0061] Obviously, the above embodiments are merely examples for clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the protection scope of the invention.
