Description
Technical Field
[0001] The invention relates to the technical field of lens processing, in particular to a fully automatic double-grinding-wheel horizontal CNC 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 X-axis, Y-axis and Z-axis, and the flipping of the lens needs to be performed by setting up a flipping mechanism. Therefore, during transportation, the lens is transported from the lens placement table to the flipping mechanism by the transport robot. After flipping by the flipping mechanism, the transport robot transports the lens from the flipping mechanism to the clamping mechanism. After polishing, the flipping mechanism is also required to flip it. Therefore, the overall loading and unloading efficiency is low. At the same time, when clamping the lens, it is necessary to ensure that the center of the circular lens corresponds to the axis of the lens shaft. Otherwise, when the lens shaft drives the lens to rotate and polish, the degree of polishing of different parts is different, which leads to irregularity of the polished lens. At the same time, defects such as edge collapse and white spots are easily generated during polishing, and the efficiency is low, the speed is slow, and there is slight vibration. Summary of the invention
[0004] The problem solved by the present invention is to provide a fully automatic double-grinding wheel horizontal CNC core-taking machine, which solves the problem that when the existing device is transporting the lens, the transport robot is used to move the lens on the X-axis, Y-axis and Z-axis, and the flipping of the lens needs to be performed by setting a flipping mechanism. Therefore, during transportation, the lens is transported from the lens placement table to the flipping mechanism by the transport robot. After flipping by the flipping mechanism, the transport robot transports the lens from the flipping mechanism to the clamping mechanism. After grinding, the flipping mechanism is also required to flip it. Therefore, the overall loading and unloading efficiency is low. At the same time, when clamping the lens, it is necessary to ensure that the center of the circular lens corresponds to the axis of the lens shaft. Otherwise, when the lens shaft drives the lens to rotate and grind, the degree of grinding of different parts is different, which leads to irregularity of the lens after grinding.
