Benefits of technology

[0022]According to the lens-processing device of the present invention, lens processing can be performed using lens-processing modes in which the lens surface is processed such that the lens is always maintained in a horizontal state. In these lens-processing modes, the pressing stress of the lens on the circular-arc-shaped processing surface of the lens-processing tool is uniform on all the portions of the lens surface. When the pressing force on the lens holder shaft is removed, and the lens that is held by suction on the lens holder that is supported on the end thereof is released, the lens does not fall and break along the circular-arc-shaped processing surface of the lens-pro

Embodiment Construction

[0027]Embodiments of a lens-processing device in which the present invention is applied will be described below with reference to the drawings.

[0028]As described in FIGS. 1 and 2, a lens-processing device 1 according to the present embodiment has an upper axial unit 10, a lower axial unit 30 that is positioned directly below the upper axial unit 10, a conveyor unit 50 that is positioned at a height between the upper axial unit 10 and the lower axial unit 30, and a drive control unit 70 that governs drive control of the various parts.

[0029]The upper axial unit 10 holds a lens holder 12 in a downward-oriented state, where the purpose of the lens holder is to hold a lens 11 to be processed. The lower axial unit 30 holds a lens-processing tool 31 in an upward-oriented state, where the lens-processing tool is used for processing the lens surface. The conveyor unit 50 supplies the lens 11 to be processed to the lens holder 12 and retrieves the lens 11 from the lens holder 12 after the com...

Abstract

A lens processing device (1) is adapted such that a lens (11) is sucked and held by a lens holder (12) rotatably and rockably supported on the front end of a lens holder shaft (13) through a pivot bearing mechanism (14) and then such that a lens surface (11a) is processed by moving the lens (11) and a lens processing tool (31) relative to each other with the lens processing tool (31) pressed to the lens (11). The lens (11) can be moved along a desired trajectory on a vertical plane containing a Z-axis and an X-axis, which are perpendicular to each other, by controlling feeding of the lens holder (12) in the Z-axis and X-axis directions by means of a Z-axis movement mechanism (19) and an X-axis movement mechanism (15). Thus, the lens surface (11a) can be processed with the lens (11) horizontally pressed to a circular arc-shaped processing surface (31a) of the lens processing tool (31).

Description

TECHNICAL FIELD[0001]The present invention relates to a highly versatile lens-processing device that can polish, cut, or otherwise process a lens surface using a variety of processing methods.BACKGROUND ART[0002]Well-known conventional methods for processing lens surfaces include Oscar-type, inclined-axis-type, spherical-oscillation-type, and planetary-oscillation-type methods. The optimal processing method is chosen from among these processing methods according to the shape, material, and other properties of the lens; and the lens surface is processed using a lens-processing device that is specialized for processing using the selected processing method. Conventionally, lens-processing devices of various formats must therefore be separately prepared, and problems are accordingly presented in that equipment costs and installation space increase, which presents economic drawbacks.[0003]In Patent Document 1 (Japanese Patent No. 3981326), the present applicants proposed a lens-processin...
