Description

Technical Field

[0001] The invention relates to the technical field of lens processing, in particular to a fully automatic core-fixing three-grinding-wheel numerically controlled horizontal core-taking machine. Background Art

[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 transporting the lens, the transport robot is used to move the lens on the XI axis, YI axis and 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 and ZI axis 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, and the third grinding wheel can be finely ground and polished. After completion, the second suction nozzle for taking the material sucks the ground lens to the alignment cylinder, flips it, and then the first suction nozzle takes the material and places it at the lens placement position. Summary of the invention

[0004] The problem solved by the present invention is to provide a fully automatic centering three-wheel numerically controlled horizontal core extracting machine, which solves the problem that the existing device cannot automatically center when grinding lenses, and the existing core extracting machine can only perform a core-swinging action, which will cause tiny scratches on the lens.
