[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] Please refer to Figure 1-3 The lens edger shown in the figure includes a fixed plate 1, and both sides of the upper end of the fixed plate 1 are fixedly connected to the support plate 2, and a first screw 3 is rotatably connected between the two support plates 2. A first motor is arranged on one side of the support plate 2, and the first motor drives the first screw 3 to rotate, so that the first slider 4 can move vertically on the upper side of the fixed plate 1, and the first screw 3 is threadedly connected to the first slider 4, and the second screw 5 is rotatably connected in the first slider 4. A second motor is arranged on one side of the second screw 5, and the second motor drives the second screw 5 to rotate, so that the second slider 6 can move laterally on the bottom side of the first slider 4, and the second screw 5 is threadedly connected to the second slider 6. An empty slot is provided in the second slider 6 and a driving motor is arranged in the empty slot, and the driving motor drives the grinding rod 7 to rotate, so as to grind the edge of the lens, and the grinding rod 7 is rotatably connected to the bottom end of the second slider 6, and the fixed plate 1 is rotatably connected to the driving wheel 8. A driving motor (not shown in the figure) is arranged on the bottom side of the fixed plate 1. The driving motor drives the driving wheel 8 to rotate, which can drive the gear ring 9 to rotate, thereby changing the The position of the push plate 12 is changed, a gear ring 9 is engaged on one side of the driving wheel 8, and the gear ring 9 is rotatably connected to the fixed plate 1. The three outer sides of the gear ring 9 are engaged with an auxiliary gear 10, and the four inner sides of the gear ring 9 are fixedly connected to the first push rod 11. The first push rod 11 and the second push rod 14 are both electric push rods. The output end of the first push rod 11 is fixedly connected to the push plate 12, and a circular groove is provided on the fixed plate 1. The fixed plate 1 is fixedly connected to a bracket 13 at the bottom side of the circular groove. The upper end of the bracket 13 is fixedly connected to the second push rod 14. The second push rod 14 The output end is fixedly connected to a connecting plate 15, and a vacuum suction cup 16 is fixedly connected to the upper end of the connecting plate 15. A vacuum pump is arranged on the bottom side of the connecting plate 15, and cooperates with a vacuum generator to enable the vacuum suction cup 16 to adsorb the lens. The first screw 3 is located at the center of the two support plates 2 and is threadedly connected to a third slider 17. A center locator 18 is fixedly connected to the center of the bottom end of the third slider 17. The center locator 18 is positioned by precise optical or mechanical methods, and more precise lens center point positioning is achieved through laser technology and sensors.

[0018] The support rods 19 are fixedly connected to the four sides of the upper end of the connecting plate 15. The support rods 19 are in a telescopic structure. The support rods 19 can provide auxiliary support on the bottom side of the lens.

[0019] The lens contacts the ball 20, and the ball 20 is rotatably embedded in the movable end of the support rod 19. The arrangement of the ball 20 reduces the friction between the support rod 19 and the lens when in contact.

[0020] Among them, an auxiliary rod 21 is movably connected to the bracket 13, and the auxiliary rod 21 is connected to the four sides of the bottom end of the connecting plate 15. By setting the auxiliary rod 21, the stability of the connecting plate 15 can be increased, thereby making the vacuum suction cup 16 more stable during adsorption processing.

[0021] The lens corresponds to the sliding ball 22 , and the sliding ball 22 is rotatably embedded in the push plate 12 . By setting the sliding ball 22 to contact the side of the lens, the friction between the push plate 12 and the lens is reduced.

[0022] Working principle: Place the lens on the vacuum suction cup 16, while the other positions of the lens are in contact with the support rod 19, then the first screw 3 is rotated so that the third slider 17 is at the center point of the upper end of the fixed plate 1, and then the center point of the lens is located using the center locator 18, and then the first push rod 11 and the push plate 12 are extended and contracted to adjust the center point of the lens to correspond to the center point of the center locator 18, and then the push plate 12 continues to extend and contact the lens, and then prompts the second push rod 14 to extend. At this time, the lens is limited by the sliding ball 22, and then the vacuum pump is used to generate adsorption force and make the vacuum suction cup 16 adsorb the lens, and then start the first motor and the second motor, and prompt the first screw 3 and the second screw 5 to rotate. At this time, the driving motor and the polishing rod 7 can move at the edge of the lens, which can achieve the effect of polishing the edge of the lens and avoid the influence of the fixture on the lens polishing.
