[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: an optical lens high-efficiency polishing machine, comprising a rectangular frame, support feet are provided at the four corners of the lower surface of the rectangular frame, a support plate is provided on the back of the rectangular frame, a clamping mechanism is provided inside the rectangular frame, a collection mechanism is provided on the upper surface of the rectangular frame, and polishing assemblies are provided on the upper and lower sides of the front of the support plate;

The left and right arc-shaped clamping blocks can be used to clamp and fix the left and right sides of the outer side of the optical lens, thereby improving the stability of polishing. Since the fixing port is opened on the lower surface of the rectangular frame, the debris generated during the polishing of the optical lens will not fall into the inside of the rectangular frame, thereby improving the stability of the normal operation of the clamping structure.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] See also Figure 1 In this embodiment, an efficient polishing machine for optical lenses includes a rectangular frame 1, and supporting feet 2 are provided at the four corners of the lower surface of the rectangular frame 1. A supporting plate 3 is provided on the back of the rectangular frame 1. A clamping mechanism 4 is provided inside the rectangular frame 1. The clamping mechanism 4 improves the stability of the normal operation of the clamping structure. A collecting mechanism 5 is provided on the upper surface of the rectangular frame 1. The collecting mechanism 5 can collect dust and debris generated during polishing. Polishing components are provided on the upper and lower sides of the front of the support plate 3.

[0033] In this embodiment, the polishing assembly includes a fixing plate 6 fixed on the upper and lower sides of the front of the support plate 3, and the opposite sides of the upper and lower fixing plates 6 are equipped with electric push rods 7. The outer sides of the output shafts of the upper and lower electric push rods 7 slide through the upper and lower fixing plates 6 and extend to the opposite side. The outer sides of the output shafts of the electric push rods 7 are fixed with connecting plates 8, and the opposite sides of the upper and lower connecting plates 8 are equipped with first motors 9. The opposite sides of the upper and lower connecting plates 8 are rotatably connected to rotating rods 10 through bearings, and the opposite sides of the upper and lower rotating rods 10 are provided with polishing blocks 11. The outer sides of the output shafts of the upper and lower first motors 9 rotate through the upper and lower connecting plates 8 and are fixedly connected to the opposite sides of the upper and lower rotating rods 10.

[0034] It should be noted that after the optical lens is fixed on the clamping rail, the upper and lower electric push rods 7 can be started synchronously to drive the upper and lower connecting plates 8 to move in relative directions. At this time, the opposite sides of the upper and lower polishing blocks 11 are in contact with the upper and lower surfaces of the optical lens. Then the upper and lower first motors 9 are started at the same time, and the outer sides of the output shafts of the upper and lower first motors 9 drive the upper and lower rotating rods 10 to rotate, and then the upper and lower polishing blocks 11 rotate. The upper and lower rotating polishing blocks 11 can polish the upper and lower surfaces of the optical lens at the same time, which can improve the polishing efficiency of the optical lens.

[0035] See also Figures 2 to 3 In order to improve the stability of the normal operation of the clamping structure, in this embodiment, the clamping mechanism 4 includes a first threaded rod 41, two moving blocks 42, a fixing port 43, four connecting frames 44, a second motor 45, two connecting blocks 46 and two arc-shaped clamping blocks 47. The first threaded rod 41 is rotatably connected to the inside of the rectangular frame 1 through a bearing, and the two moving blocks 42 are both threadedly connected to the outside of the first threaded rod 41. The moving blocks 42 are slidably connected to the inside of the rectangular frame 1. The fixing port 43 is opened on the lower surface of the rectangular frame 1. The four connecting frames 44 are fixed to the front and rear sides of the lower surface of the left and right moving blocks 42. The second motor 45 is assembled on the left side of the rectangular frame 1. The outer side of the first threaded rod 41 is engraved with threads in opposite directions. When the first threaded rod 41 rotates, the left and right moving blocks 42 can be synchronously moved in relative directions or synchronously moved in opposite directions on the outside of the first threaded rod 41.

[0036] In this embodiment, the second motor 45 can be started to drive the first threaded rod 41 inside the rectangular frame 1 to rotate, and the two moving blocks 42 threadedly connected to the outside of the first threaded rod 41 move synchronously in relative directions, driving the left and right side connecting frames 44 and the left and right side connecting blocks 46 to move in relative directions, and then the left and right side arc-shaped clamping blocks 47 move synchronously in relative directions.

[0037] The outer side of the output shaft of the second motor 45 rotates through the rectangular frame 1 and is fixedly connected to the left side of the first threaded rod 41. The two connecting blocks 46 are fixed on the opposite sides of the left and right connecting frames 44, and the two arc-shaped clamping blocks 47 are fixed on the opposite sides of the left and right connecting blocks 46.

[0038] In this embodiment, the moving block 42 matches the gap of the rectangular frame 1 , and the moving block 42 moves linearly left and right inside the rectangular frame 1 . The fixing opening 43 is located on the longitudinal center axis of the rectangular frame 1 .

[0039] It should be noted that the left and right sides of the outer side of the optical lens can be clamped and fixed by the arc-shaped clamping blocks 47 on the left and right sides, thereby improving the stability of polishing. Since the fixing port 43 is opened on the lower surface of the rectangular frame 1, the debris generated during the polishing of the optical lens will not fall into the inside of the rectangular frame 1, thereby improving the stability of the normal operation of the clamping structure.

[0040] See also Figure 4 In order to collect the dust and debris generated during polishing, in this embodiment, the collection mechanism 5 includes a collection frame 51, two limit plates 52, two second threaded rods 53, two handles 54 and two slots 55. The collection frame 51 is placed on the upper surface of the rectangular frame 1, and the two limit plates 52 are fixed on the left and right sides of the upper surface of the rectangular frame 1. The opposite sides of the left and right limit plates 52 are both in contact with the left and right sides of the collection frame 51, and the second threaded rod 53 is threadedly connected to the inside of the limit plate 52. The two handles 54 are fixed on the opposite sides of the left and right second threaded rods 53. The two side slots 55 are both opened on the left and right sides of the collection frame 51, and the opposite sides of the left and right second threaded rods 53 are slidably inserted into the inside of the left and right side slots 55.

[0041] In this embodiment, an anti-slip sleeve is fixed to the outside of the handle 54, and the anti-slip sleeve is a rubber sleeve. The second threaded rod 53 is matched with the gap of the slot 55, and the second threaded rod 53 moves linearly left and right inside the slot 55. The left and right side limit plates 52 are symmetrically distributed on the left and right sides of the longitudinal center axis of the rectangular frame 1.

[0042] It should be noted that the dust and debris generated during the polishing of the optical lens can fall into the interior of the collection frame 51 for collection. By twisting the left and right handles 54, the left and right second threaded rods 53 are driven to rotate inside the left and right limit plates 52 and move in opposite directions. The left and right second threaded rods 53 are moved out of the left and right slots 55 on the outside of the opposite side, and then the collection frame 51 can be disassembled from the upper surface of the rectangular frame 1 to facilitate cleaning of the dust and debris collected inside the collection frame 51.

[0043] The working principle of the above embodiment is:

[0044] (1) The second motor 45 can be started to drive the first threaded rod 41 inside the rectangular frame 1 to rotate, and the two moving blocks 42 threadedly connected to the outside of the first threaded rod 41 can move in synchronous relative directions, driving the left and right side connecting frames 44 and the left and right side connecting blocks 46 to move in relative directions, and then the left and right side arc-shaped clamping blocks 47 can move in synchronous relative directions. The left and right sides of the outer side of the optical lens can be clamped and fixed by the left and right side arc-shaped clamping blocks 47 to improve the stability of polishing. Since the fixing port 43 is opened on the lower surface of the rectangular frame 1, the debris generated during the polishing of the optical lens will not fall into the inside of the rectangular frame 1, thereby improving the stability of the normal operation of the clamping structure.

[0045] (2) After the optical lens is fixed on the clamping rail, the upper and lower electric push rods 7 can be started synchronously to drive the upper and lower connecting plates 8 to move in relative directions. At this time, the opposite sides of the upper and lower polishing blocks 11 are in contact with the upper and lower surfaces of the optical lens. Then the upper and lower first motors 9 are started simultaneously. The outer sides of the output shafts of the upper and lower first motors 9 drive the upper and lower rotating rods 10 to rotate, and then the upper and lower polishing blocks 11 rotate. The upper and lower rotating polishing blocks 11 can polish the upper and lower surfaces of the optical lens at the same time, which can improve the polishing efficiency of the optical lens. The dust and debris generated during the polishing of the optical lens can fall into the collection frame 51 for collection. By twisting the left and right handles 54, the left and right second threaded rods 53 are driven to rotate inside the left and right limit plates 52 and move in opposite directions. The outer sides of the opposite sides of the left and right second threaded rods 53 are moved out of the left and right slots 55. Then the collection frame 51 can be disassembled from the upper surface of the rectangular frame 1 to facilitate cleaning of the dust and debris collected inside the collection frame 51.
