Embodiment 1

[0053] This embodiment is a numerically controlled optical lens edge cutting machine. The edge cutting machine includes a 5-axis numerical control and motion system, a lens edge profile measurement system, an in-situ optical center and astigmatism axis positioning system, at least one workpiece axis, tool axis 2 and Vacuum adsorption lens loading system;

[0054] 5-axis CNC and motion system includes XYZBC axis, X axis is the horizontal axis, Y axis is the vertical axis, Z axis is the vertical axis, the B axis rotates around the Y axis, and the C axis rotates around the Z axis;

[0055] The tool shaft 2 is installed on the X-axis, and the camera 1 and the tool shaft 2 can move along the X-axis and Z-axis; the tool shaft 2 is provided with a handle 7 and a tool 8;

[0056] For the convenience of installation, it is preferable to use two linked double workpiece axes, but the workpiece axes are not limited to two, and can be extended to three, four, five, etc., and the double workp...

Embodiment 2

[0076] The difference between this embodiment and Embodiment 1 lies in the setting of the position of the workpiece axes. In this embodiment, dual workpiece axes are still selected, but the workpiece axes are arranged back-to-back symmetrically with respect to the rotation axis, as shown in Figure 4 As shown, but the workpiece axes are not limited to two, and can be extended to four, six, eight, etc., and the other structures are the same as in the first embodiment.

Embodiment 3

[0078] The difference between this embodiment and Embodiment 1 lies in the setting of the position of the workpiece axis. In this embodiment, four workpiece axes are selected, and the workpiece axes are installed on a rotating drum 14, and the rotation of the rotating drum 14 sequentially switches the lens to the working position for processing. ,Such as figure 2 Shown, but not limited to four, enlarge the size of the drum 14, more workpiece shafts can be installed on the drum 14, and other structures are the same as the first embodiment. This design is suitable for cutting aphotic lenses, such as sunglasses and frame spacers.

Abstract

The invention provides a novel numerical control optical lens edge cutting machine which can automatically locate the optical center, the astigmatic axis position and an edge contour of a lens, perform diamond edge cutting and perform operation on multiple lens. The novel numerical control optical lens edge cutting machine comprises a 5-axis numerical control and movement system, a lens edge contour measuring system, an in-position optical center and astigmatic axis position locating system, at least one workpiece shaft, a tool shaft and a vacuum lens suction loading system. The novel numerical control optical lens edge cutting machine is suitable for edge cutting for various kinds of lens for glasses.

Description

technical field [0001] The invention relates to an optical lens edge cutting machine, in particular to a numerically controlled optical lens edge cutting machine capable of automatically positioning or measuring the optical center, astigmatism axis, and edge contour of a lens, and capable of operating multiple lenses. Background technique [0002] Nowadays, more and more people wear glasses. There are people with myopia caused by eye fatigue, and middle-aged and elderly people with aging eye function degeneration. The demand for spectacle lenses for eye protection is rising. It is impossible to leave glasses, or myopia, or aging in a person's life. It is precisely because everyone cannot do without glasses, so the base of glasses is very large. From the spectacle lenses that come out of the factory to the wearable glasses, there is an important process in the middle, which is to cut and assemble according to the shape of the frame and the parameters of the optometry sheet....
