In this embodiment, the lower grinding seat 23 is cylindrical; an installation groove 231 is formed in the top wall of the lower grinding seat 23, and the lower grinding disc 24 is installed in the installation groove 231.

[0033] See Figure 1 and Figure 2 , the drive motor 26 is installed on the outer bottom wall of the bottom shell 22, and the output shaft of the drive motor 26 is coaxially fixed to the drive shaft 25. Start the drive motor 26 to drive the drive shaft 25 to drive the lower grinding seat 23 to rotate, so that the lower grinding disc 24 can grind the optical lens.

[0034] See Figure 1 and Figure 2 , the upper grinding assembly 3 includes: an upper grinding seat 31, an upper grinding disc 32 and a hydraulic cylinder 33. The hydraulic cylinder 33 is installed on the bracket 21. The hydraulic cylinder 33 is located above the upper grinding disc 32, and the output end of the hydraulic cylinder 33 is fixedly connected to the upper grinding seat 31. The upper grinding disc 32 is installed on the bottom wall of the upper grinding seat 31. During grinding, start the hydraulic cylinder 33 to control the lower grinding seat 23 to descend until the upper grinding disc 32 contacts the optical lens, so as to jointly grind the optical lens with the lower grinding disc 24. In this embodiment, a grinding liquid and a coolant are provided on the upper grinding seat 31, and the specific conveying method can adopt a pump body (not shown in the specific structure diagram, and all adopt existing technologies) so that the grinding liquid and the coolant can be sprayed during grinding.

Lifting grooves 221 are formed in the top walls of the sleeve plate 27 and the bottom shell 22, and the actual dimensions are determined according to the dimensions of the sleeve plate 27 and the bottom shell 22; and the lifting plate 201 is arranged in the lifting groove 221, and the lifting plate 201 can move up and down in the vertical direction; the lifting spring 202 is fixed between the bottom wall of the lifting plate 201 and the bottom of the lifting groove 221, and the lifting spring 202 is used to support the lifting plate 201.

[0036] See Figure 4 and Figure 5, the internal tooth column 28 is fixed to the top wall of the lifting plate 201 corresponding to the sleeve plate 27. In this embodiment, there are multiple internal tooth columns 28, which are evenly distributed along the circumferential direction of the lifting plate 201; the external gear is fixed to the top wall of the lifting plate 201 corresponding to the bottom case 22. In this embodiment, there are multiple external tooth columns 29, which are evenly distributed along the circumferential direction of the lifting plate 201, and the diameters of the internal tooth column 28 and the external tooth column 29 are equal.

When the upper grinding disc 32 descends, the upper grinding disc 32 will contact the mold 1 and press down on the mold 1; during this process, the lifting spring 202 is compressed, that is, the lifting plate 201 descends until the optical lens contacts the lower grinding disc 24; then, the driving motor 26 is started to drive the lower grinding seat 23 to drive the lower grinding disc 24 to rotate, so as to grind the optical lens; at the same time, the driving shaft 25 can drive the sleeve plate 27 to rotate, so that the mold 1 can rotate self - sufficiently to further improve the grinding effect; During the grinding process, if the thickness of the optical lens needs to be thinner, then the lower grinding disc 24 can be further lowered so that the optical lens can always be in contact with the lower grinding disc 24, thereby improving the applicability.

[0037] See Figure 3 , the cleaning mechanism includes: a cleaning component 4, a first limiting component 5, a transmission component 6 and a second limiting component 7.

[0038] See Figure 3 、 Figure 4 and Figure 6 , the cleaning component 4 includes: a rotating ring 41, a rotating plate 42, a connecting rod 43, a telescopic cylinder 44, a telescopic rod 45, a telescopic spring 46, a support rod 47 and a cleaning brush 48. The rotating ring 41 is rotatably sleeved on the lower grinding seat 23. In the embodiment of the present application, the rotational connection can all adopt bearings; the rotating plate 42 is sleeved on the lower grinding seat 23, and the rotating ring 41 is located below the rotating plate 42. The telescopic cylinder 44 is fixed to the top wall of the rotating ring 41; one end of the telescopic rod 45 is arranged in the telescopic cylinder 44 and the other end is fixed to the top wall of the rotating plate 42; the telescopic spring 46 is sleeved on the telescopic rod 44 and one end is fixed to the rotating plate 42 and the other end is fixed to the telescopic cylinder 44. The telescopic spring 46 is used to support the rotating plate 42.

[0039] The top wall of the lower grinding platen 24 is radially penetrated with a relief groove, and the top wall of the bottom shell 22 is provided with a through groove 232. The relief groove and the through groove 232 are mainly used to make way for the rod part of the cleaning brush 48, so that the cleaning brush 48 can move up and down. The cleaning brush 48 is fixed to one side of the rotating plate 42 close to the lower grinding platen 24 and is horizontally arranged. When the upper grinding platen 32 is not in contact with the optical lens, the top end of the cleaning brush 48 is lower than the bottom end of the mold 1 (considering the thickness of the optical lens, further speaking, after the optical lens is installed on the mold 1, the top end of the cleaning brush 48 is lower than the bottom end of the optical lens).

[0040] A sliding groove 222 is vertically penetrated on one side of the lifting groove 221 close to the lower grinding base 23. One end of the connecting rod 43 is fixed to the outer side wall of the rotating plate 42, and the other end passes through the sliding groove 222 and is fixed to the lifting plate 201. That is, through the setting of the connecting rod 43, the rotating plate 42 can be lifted and lowered together with the lifting plate 201. One end of the support rod 47 is fixed to the rotating ring 41, and the other end is slidably arranged on the inner side wall of the bottom shell 22. The support rod 47 is used to better support the lower grinding base 23. After grinding for a period of time, the upper grinding platen 32 is lifted to be separated from the optical lens. During this process, the lifting plate 201 will drive the rotating plate 42 to rise, so that the cleaning brush 48 will pass through the relief groove and the through groove 232 and rise above the lower grinding platen 24. Then, control the driving motor 26 to drive the driving shaft 25 to rotate in the reverse direction, so that the rotating ring 41 can drive the rotating plate 42 to rotate, so that the cleaning brush 48 can clean the top wall of the lower grinding platen 24, so as not to easily affect the grinding effect of the lower grinding platen 24 on the optical lens (since the upper grinding platen 32 will spray coolant or grinding fluid, the dust and debris on the upper grinding platen 32 are easily dropped onto the lower grinding platen 24), thereby improving the accuracy and surface quality of the optical lens. And every time it rotates one week, the cleaned dust and debris can fall from the relief groove into the installation groove 231. In the embodiment of the present application, a collection tank body can be embedded on the lower grinding base 23, and a falling hole communicating with the collection tank body is opened in the installation groove 231. Then, a flip door (not shown in the figure) is installed on the bottom shell 22, so that the dust and debris can fall into the collection tank body and be taken out regularly.

[0041] See Figure 7, the first limiting component 5 includes: a coaxial rod 51, a first limiting rod 52 and a first limiting spring 53.

One end of the coaxial rod 51 is fixedly connected to the first shaft 251, and the other end is arranged in the coaxial hole 2521. A receiving hole 511 is formed in the side wall of the coaxial rod 51. One end of the first limiting rod 52 is arranged in the first limiting hole 2522, and the other end is arranged in the receiving hole 511. The first limiting spring 53 is fixed between the first limiting rod 52 and the bottom of the receiving hole 511. The first limiting spring 53 is used to push the first limiting rod 52 to insert into the first limiting hole 2522.

[0042] See Figure 7 , an inclined first guiding surface 521 is arranged at one end of the first limiting rod 52 away from the first limiting spring 53, and one end of the first guiding surface 521 close to the first limiting spring 53 extends out of the first limiting hole 2522. When cleaning is required, the first shaft 251 is controlled to rotate reversely. During this process, through the arrangement of the first guiding surface 521, the first limiting rod 52 can be pressed back into the receiving hole 511, so as to release the limit on the second shaft 252, so as not to drive the second shaft 252 to rotate, and then it is convenient to drive the rotating ring 41 to rotate, so as to drive the cleaning brush 48 to clean.

[0043] See Figure 3 , the transmission component 6 includes: a wrapping shell 61, a first transmission rod 62, a second transmission rod 63, a first transmission belt 64 and a second transmission belt 65.

When the first shaft 251 rotates reversely, the first shaft 251 can drive the rotation of the first transmission belt 64, the first transmission rod 62, the second transmission rod 63 and the second transmission belt 65 in sequence, so that the second transmission belt 65 can drive the rotating ring 41 to rotate.

[0045] See Figure 8The second limiting assembly 7 includes: an insertion rod 71, a second limiting rod 72 and a second limiting spring 73. The bottom wall of the second transmission rod 63 is provided with an insertion hole 631, and the inner side wall of the insertion hole 631 is provided with a second limiting hole 632.

A placement hole 711 is provided on the side wall of the insertion rod 71. One end of the second limiting rod 72 is arranged in the placement hole 711, and the other end is arranged in the second limiting hole 632. The second limiting spring 73 is fixed between the second limiting rod 72 and the bottom of the placement hole 711, and the second limiting spring 73 is used to push the second limiting rod 72 to be inserted into the second limiting hole 632.

[0046] See also Figure 8 The second limiting rod 72 is provided with an inclined second guide surface 721 at one end away from the second limiting spring 73, and the second guide surface 721 extends out of the second limiting hole 632 at one end close to the second limiting spring 73. When the shaft 251 rotates in the opposite direction, the second limiting rod 72 can limit the second transmission rod 63, so that the first transmission rod 62 can drive the second transmission rod 63; during the grinding process, through the setting of the second guide surface 721, the second limiting rod 72 can be pressed back into the placement hole 711, thereby releasing the limitation on the second transmission rod 63 so as not to affect the grinding of the optical lens.

[0047] See also Figure 3 Furthermore, the cleaning mechanism also includes: a pressure assembly 8, the pressure assembly 8 includes: a pressure plate 81, a rubber pad 82 and a fixing rod 83, the lifting groove 221 is close to one side of the lower grinding seat 23 and is provided with a through groove 223 in the vertical direction, one end of the fixing rod 83 is fixed to the pressure plate 81, and the other end is penetrated by the through groove 223 and fixedly connected to the lifting plate 201; the pressure plate 81 is located below the lower grinding seat 23.

[0048] See also Figure 3 The rubber pad 82 is fixed on the top wall of the pressure plate 81, and the rubber pad 82 abuts against the bottom wall of the lower grinding seat 23. The rubber pad 82 is used to increase the friction between the pressure plate 81 and the lower grinding seat 23. After the lifting plate 201 rises, the pressure plate 81 abuts against the lower grinding seat 23, so that the lower grinding seat 23 is not easy to rotate during the cleaning process, thereby ensuring that after cleaning, the cleaning brush 48 can still be lowered through the make way groove and the penetration groove 232.
