[0054] Before flipping the spherical lens 5, the first rotating drive assembly 12 does not work, the vacuum nozzle 22 is connected to the vacuum tube, the vacuum nozzle 22 sucks the first surface 51 of the spherical lens 5, and then the spherical lens 5 is placed between the first lens clamp 112 and the second lens clamp 113. The telescopic end of the first telescopic drive assembly 15 extends to the right, pushing the first connecting rod 17 to move horizontally to the right, and the first connecting rod 17 drives the first straight gear 13 and the first sliding rod 110 to move horizontally to the right, so that the first lens clamp 112 moves toward the spherical lens 5. The second spur gear 14 is closer to the spherical lens 5, and the thickness of the second spur gear 14 is greater than that of the first spur gear 13. The telescopic end of the second telescopic drive assembly 16 extends to the left, pushing the second connecting rod 18 to move horizontally to the left. The second connecting rod 18 drives the second sliding rod 111 to move horizontally to the left, so that the second lens clamp 113 moves closer to the spherical lens 5, so that the first lens clamp 112 and the second lens clamp 113 clamp the spherical lens 5 together. The vacuum nozzle 22 is separated from the spherical lens 5, and the first surface 51 of the spherical lens 5 is facing upward and the second surface 52 is facing downward.

[0055] Start flipping the spherical lens 5; the first lens clamp 112 and the second lens clamp 113 remain in a clamped state, the rotating end of the first rotating drive assembly 12 drives the second spur gear 14, and the second spur gear 14 causes the first spur gear 13 to rotate, and the first spur gear 13 drives the first connecting rod 17, the first sliding rod 110, the first lens clamp 112, the flip fixture support 19, the second lens clamp 113, the second sliding rod 111 and the second connecting rod 18 to rotate, thereby flipping the spherical lens 5 180°.

The telescopic end of the first telescopic drive assembly 15 retracts, and the telescopic end of the second telescopic drive assembly 16 retracts, so that the first lens clamp 112 and the second lens clamp 113 release the spherical lens 5.

[0056] The spherical lens 5 is chamfered; the vacuum suction nozzle 22 places the spherical lens 5 on the grinding cup 31, and the edge of the first surface 51 or the edge of the second surface 52 of the spherical lens 5 contacts the grinding cup 31. The vacuum suction nozzle 22 maintains suction, and then starts the second rotating drive assembly 33.

The beneficial effect of this technical solution is that the spring pin 24 is added to effectively provide a certain downward pressure to the spherical lens 5, and due to the elastic deformation of the spring pin 24, a buffering effect is provided, thereby reducing the hard-to-hard pressure between the spherical lens 5 and the grinding cup 31, and preventing the spherical lens 5 from cracking. Adding a vertical guide rod 25 between the spring pins 24 can avoid uneven force on the spring pins 24 on both sides, which will cause the plane of the vacuum nozzle 22 below to have an inclination angle, thereby affecting the flatness of the spherical lens; it helps to make the milling degree of each spherical lens 5 consistent.

The second compression spring 115 is sleeved on the second slide bar 111 and is also located between the right baffle plate 192 and the second lens clamp 113. The beneficial effect of this technical solution is that when the first compression spring 114 and the second compression spring 115 are both in the reset state, it helps the first lens clamp 112 and the second lens clamp 113 to stably clamp the spherical lens 5, and prevents the first lens clamp 112 and the second lens clamp 113 from loosening due to external vibration of the telescopic ends of the first telescopic driving assembly 15 and the second telescopic driving assembly 16.

[0061] The lens flipping mechanism 1 further comprises a first sleeve 116 and a second sleeve 117, wherein the left end of the first sleeve 116 is fixedly connected to the first telescopic drive assembly 15, the first connecting rod 17 can enter and exit the right end of the first sleeve 116, the right end of the second sleeve 117 is fixedly connected to the second telescopic drive assembly 16, and the second connecting rod 18 can enter and exit the left end of the second sleeve 117.

then the spherical lens moves upward and is transported to the flipping fixture support platform of the lens flipping mechanism, the first telescopic driving assembly and the second telescopic driving assembly respectively clamp the spherical lens with the first lens clamping block and the second lens clamping block, and at the same time, sliding occurs between the first spur gear and the second spur gear; then Afterwards, the first rotating drive assembly drives the second spur gear to rotate, and the first spur gear rotates with the second spur gear, so that the flipping fixture support, the first lens clamp, the second lens clamp, and the spherical lens are flipped at the same time, so that the second side of the spherical lens faces upward; the vacuum suction nozzle of the lens suction mechanism moves to the position of the flipping fixture support, sucks the second side of the spherical lens, the first telescopic driving assembly and the second telescopic driving assembly respectively release the spherical lens from the first lens clamp and the second lens clamp, and the vacuum suction nozzle transports the spherical lens to the grinding cup position again, the periphery of the first side of the spherical lens contacts the grinding cup in a rotating state, and is milled and cut by the grinding cup to form a chamfer on the first side, and finally the lens suction mechanism puts the chamfered spherical lens back into the lens placement box.
