Lens centering machine

Abstract

PURPOSE: A lens chamfering machine is provided to decrease the installation area of the machine by restricting the dead space on the work table, and to increase the productivity and reduce working hours and energy consumption by continuously performing the first process and the second process in the same machine. CONSTITUTION: A lens chamfering machine comprises a work table(7) for storing and placing a work piece to be processed or the finished work piece, a loader(9) transferring the work piece from the work table to the processing position, a supporting frame(13) placed near the work table, two sets of processing units(10a,10b) supported in the supporting frame with the work table and operated independently, two couples of operating shafts arranged in parallel at both sides or in the upper and lower parts of the supporting frame, two wheel spindle stocks(14) guided in parallel with the operating shafts or perpendicularly to the operating shafts, and grinding wheels(6) axially supported in the wheel spindle stocks and placed on the work table.

Description

technical field [0001] The present invention relates to a lens centering machine for processing the outer periphery of a lens based on the optical axis, and to a device for grinding the outer periphery of a lens clamped by cup-shaped fixtures at the opposite ends of a set of workpiece axes that are installed on the same axis and rotate synchronously . Background technique [0002] Lens aligning machine with general structure, such as Figure 11 As shown, the spherical surface of the lens 5 is held by cup-shaped lens holders 3 and 4, and the holders 3 and 4 of the cup-shaped lens are installed on the opposite ends of the moving-side workpiece shaft 1a and the fixed-side workpiece shaft 1b arranged on the same axis, synchronously The workpiece shafts 1a, 1b are rotated, and the grinding stone 6 adjacent to the workpiece shafts is servo-controlled in the parallel direction (Z direction) and the direction (X direction) of the workpiece shafts to process the outer periphery of th...

Problems solved by technology

[0016] In addition, the hand 40 of the conveying head for conveying the lens needs to increase its length in order to avoid interference with various components installed near the processing position 41, but in this case, the movable area of ​​the hand tip on the workpiece table 7 is limited to the workpiece. Near side of processing position 41 of table 7

That is, on the side away from the processing position 41 of the workpiece table 7, since the front end of the hand 40 cannot move, a dead zone where the workpiece 5 cannot be placed is generated, and the installation space of the device including the workpiece table 7 becomes large.
