[0002] During the lens processing, the horizontal CNC core removal machine is used to automatically load and unload the lenses and grind their edges.
[0003] When the existing device is used to transport the lens, the transport robot is used to move the lens on the second module of the XI axis, the first module of the YI axis and the third module of the ZI axis, and the flipping of the lens needs to be performed by setting a flipping mechanism. Therefore, when transporting, the lens is transported from the lens table to the flipping mechanism by the transport robot. After flipping through the flipping mechanism, the transport robot transports the lens from the flipping mechanism to the clamping mechanism, and then transports the lens to the center of the DD motor of the centering mechanism for full-automatic centering. After the centering is completed, the transport arm YI axis first module and ZI axis third module transport the lens to the left lens axis for the second center check. After the center check is OK, the lens is clamped and then enters the grinding stage. Coarse, medium and fine grinding can be performed, or the first grinding wheel and the second grinding wheel can be ground at the same time, the third grinding wheel can be finely ground, and the fourth grinding wheel can be polished. After completion, the second suction nozzle of the material pick-up sucks the ground lens to the alignment cylinder, flips it, and then the first suction nozzle picks up the material and places it at the lens placement position.
