[0040] Reference Figure 5 , 6As shown, the swing drive assembly 32 includes a swing drive motor 321, a swing drive driving wheel 322, a gear belt 323 and a swing drive driven wheel 324. The swing drive motor 321 is fixedly mounted on the grinding machine table 1, and the swing drive motor 321 is provided with a swing drive driving wheel 322. The swing drive driving wheel 322 is connected to the swing drive driven wheel 324 through the gear belt 323. The swing drive driven wheel 324 is mounted on one end of the swing drive shaft 33 away from the connecting plate 34. The swing drive motor 321 rotates to drive the swing drive active wheel 322 to rotate, and drives the swing drive driven wheel 324 to rotate through the gear belt 1 323, so that the swing drive shaft 33 rotates on the shaft support seat 31. When grinding the lens, the swing drive motor 321 needs to continuously switch between forward and reverse rotations, and drives the swing drive shaft 33 to switch between forward and reverse rotations through the transmission of the swing drive active wheel 322, the gear belt 1 323 and the swing drive driven wheel 324, so that the connecting plate 34 switches between forward and reverse rotations. The forward and reverse switching of the connecting plate 34 formed in this way is a small-angle rotation. Therefore, during the forward and reverse switching of the connecting plate 34, the upper swing head 312 swings back and forth, so that the lens to be ground in the upper swing head 312 is ground by the grinding head on the lower grinding device 2.
[0041] The swing drive assembly 32 can drive the upper swing head 312 to stop the vertical position when the upper swing head 312 stops, so as to facilitate automatic loading.
[0042] The working principle of the upper swing device 3 is as follows:
[0043] When the upper swing head 312 is lifted, the three-axis moving platform 5 and the lens loading assembly 6 will send the lens to be polished to the bottom of the upper swing head 312. The upper swing head 312 starts the negative pressure to absorb the lens to be polished. The swing head lifting cylinder 37 is lowered, so that the lens to be polished is close to the polishing head of the lower polishing device 2 below. There is a certain small distance between the lens to be polished and the polishing head of the lower polishing device 2. At this time, the floating cylinder 311 is ejected, pushing the lower ejector rod 303 to move downward so that the ejector pin 307 pushes the upper swing head 312 out of the circular groove 309 of the lower swing head mounting sleeve 306, and the upper swing head 312 is ejected from the lower swing head mounting sleeve 306. The upper swing head 312 is separated from the lower swing head mounting sleeve 306. At this time, the lens to be polished is restricted between the upper swing head 312 and the polishing head of the lower polishing device 2. The upper swing head 312 loses vacuum, and the swing drive motor 321 drives the upper swing head 312 to move downward. The transmission of the driving wheel 322, the gear belt 323 and the swing drive driven wheel 324 drives the swing drive shaft 33 to switch and rotate in the forward and reverse directions, thereby driving the connecting plate 34, the horizontal support plate 35, the vertical support plate 36, the swing head lifting cylinder 37, the upper pressing cylinder 38, the lifting and moving plate 39, the upper mounting plate 310, the floating cylinder 311 and the upper swing head 312 to swing back and forth. The back and forth swing of the upper swing head 312 drives the lens to be polished to swing. At this time, the grinding head of the lower grinding device 2 rotates at high speed to grind the lens. At this time, the state is that the lens to be polished will be suspended on the lower grinding head of the upper swing machine. After grinding, the floating cylinder 311 moves downward to clamp the upper swing head 312 back into the groove inside the lower swing head mounting sleeve 306. The lifting cylinder 37 rises and adsorbs the polished lens inside the upper swing head 312 and lifts it upward to separate from the grinding head.
[0044] Reference Figure 3 , 4As shown, the lower grinding device 2 includes a grinding drive motor 21, a grinding drive active wheel 22, a second gear belt, a grinding drive driven wheel 23, a grinding drive rotating shaft 24 and a lower grinding head 25.

The lower grinding head 25 is set to be hemispherical, and the grinding drive motor 21 can drive the grinding drive shaft 24 to rotate at high speed through the transmission of the grinding drive active wheel 22, the gear belt 2 and the grinding drive driven wheel 23, so that the lower grinding head 25 rotates at high speed. During the high-speed rotation of the lower grinding head 25, the swing of the swinging upper swing head 312 can be coordinated to grind the lens to be polished to form an arc-shaped inner concave surface.
[0045] The working principle of the lower grinding device 2 is:
[0046] The grinding drive motor 21 drives the lower grinding head 25 to rotate quickly, thereby grinding the lens to be ground in the upper swing head 312 .
[0047] Reference Figure 3 As shown, the grinding drive shaft 24 is connected to a cover plate 241, the cross section of the cover plate 241 is circular, and the cover plate 241 is connected to a cover cylinder 242, and the cover cylinder 242 covers the grinding drive shaft 24. The diameter of the cover cylinder 242 is smaller than the diameter of the cover plate 241. The lower end surface of the cover cylinder 242 is close to the working table of the grinding machine 1, so that during the lens grinding process, the isolation space formed by the cover plate 241 and the cover cylinder 242 can isolate the part of the grinding drive shaft 24 that leaks out of the grinding machine 1, so as to prevent dust from flying into the grinding drive shaft 24 and causing rotation jam.

[0049] Reference Fig.14 As shown, a stopper 432 is provided at the end of the feeding channel 43 away from the feeding vibration plate 42, and the stopper 432 is used to block the lens to be polished in the feeding channel 43. The cross section of the stopper 432 is T-shaped, and the small end of the stopper 432 is higher than the lens to be polished in the feeding channel 43, so that when the lens in the feeding channel 43 contacts the stopper 432, the lens to be polished is loaded in place, and the upper computer control system notifies the piston rod of the material taking driving cylinder 47 to extend and drive the material taking suction nozzle 48 to descend to absorb the lens to be polished in the feeding channel 43.
[0050] The working principle of the lens feeding device 4 is as follows:

The rectangular waterproof housing 1 511 is provided with a rectangular opening 1 512 along the moving direction of the slider of the X-axis linear module 51. The rectangular opening 1 512 is used to pass the connecting plate between the X-axis linear module 51 and the Y-axis linear module 52. The rectangular opening 1 512 is opened on the side facing away from the downward polishing device 2. Since the lower polishing device 2 needs to spray liquid when polishing the lens, the rectangular opening 1 512 is opened on the side facing away from the downward polishing device 2 to prevent liquid from entering the X-axis linear module 51. The lower end surface of the rectangular waterproof housing 2 521 is provided with a rectangular opening 2 522 along the moving direction of the slider. Since the rectangular opening 2 522 is set on the lower side, the liquid sprayed by the lower polishing device 2 when polishing the lens will not enter the rectangular waterproof housing 2 521, thereby avoiding damage to the Y-axis linear module 52. A rectangular opening three 532 is provided on one side of the rectangular waterproof shell three 531 which is away from the lower grinding device 2 in the vertical direction. Since the rectangular opening three 532 is away from the lower grinding device 2, the liquid sprayed by the lower grinding device 2 when grinding the lens will not enter the rectangular waterproof shell three 531, thereby avoiding damage to the Z-axis linear module 53. The rectangular waterproof shell one 511, the rectangular waterproof shell two 521 and the rectangular waterproof shell three 531 can form waterproof protection for the three-axis mobile platform 5.
[0053] Since a large amount of water will enter the module track during the use of the existing lens grinder, it will affect the service life and function of the module. Therefore, in view of the above existing working conditions, a new waterproof automatic feeding servo module is developed. The waterproof module prevents water from entering through a fully enclosed design on the water side of the module, thereby improving the service life and use function of the module.
[0054] Reference Fig.10As shown, the lens loading assembly 6 includes an adapter plate 61, a rotary cylinder 62, a connecting rod 63, a nozzle mounting plate 64 and two second loading nozzles 65. The adapter plate 61 is connected to the slider of the Z-axis linear module 53. The rotary cylinder 62 is mounted on the adapter plate 61. One end of the connecting rod 63 is connected to the rotary cylinder 62, and the other end of the connecting rod 63 is connected to the nozzle mounting plate 64. The two second loading nozzles 65 are arranged on the nozzle mounting plate 64. One of the two second loading nozzles 65 is used to absorb the polished lens in the upper swing head 312, and the other of the two second loading nozzles 65 is used to put the lens to be polished sucked from the lens loading device 4 into the upper swing head 312. The lens loading assembly 6 cooperates with the three-axis mobile platform 5 to realize automatic loading and unloading of lenses.
[0055] The working principle of the three-axis mobile platform 5 and the lens loading assembly 6 is:
[0056] The X-axis linear module 51, the Y-axis linear module 52 and the Z-axis linear module 53 can drive the two loading nozzles 65 to move automatically in three-dimensional space. The three-axis mobile platform 5 drives the loading nozzle 65 to come under the suction loading channel 43. One of the two loading nozzles 65 absorbs the lens to be polished adsorbed on the loading channel 43. Then the three-axis mobile platform 5 drives the loading nozzle 65 to come under the upper swing head 312. The remaining loading nozzle 65 of the two loading nozzles 65 absorbs the polished lens on the upper swing head 312. The loading nozzle 65 that has absorbed the lens to be polished puts the lens to be polished into the upper swing head 312, and the upper swing head 312 absorbs the lens to be polished and polishes it again.
[0057] 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.
