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.

Embodiment Construction

[0044] Hereinafter, embodiments of the present invention will be described with reference to the drawings. figure 1 is from the front left side ( figure 2 Arrow A direction) to see the overall perspective view of the machine of the embodiment device, figure 2 It is a schematic top view of the whole machine, image 3 is the side view of the processing unit, Figure 4 It is the top view of two groups of processing units.

[0045] exist figure 1 , figure 2 Among them, 7 is a work table, 8 is a pallet mounted on the work table 7, and the lenses 5 before and after processing are held on receiving tables provided in matrix on each pallet. 57 is the arm of the loader, which is used by the workpiece table 7 figure 2 The guide beam 56 in the up and down direction (Y direction) guides and runs directly above the workpiece table 7 . On the loader arm 57 there is an edge figure 2 The conveying head 44 that travels in the left and right direction (X direction). On the trans...

Abstract

Two pairs of processing units 10a, 10b which are supported by a support frame 13 formed on a machine frame and independently acting with each other are provided at the centering and edging machine having one work rest 7 and a loader 9 on the machine frame. The two pairs of processing units 10a, 10b sharing the machine frame, the work rest 7, and the loader 9 are provided on one machine, which realizes the centering and edging machine on which two lenses are simultaneously processed in a roughly equal installation area to the conventional centering and edging machine having only one processing unit.

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...
