Abstract

The invention provides an adjustable vacuum sucker device for assembling and adjusting a lens of a photoetching machine and relates to the technical field of the manufacturing, assembly and adjustment of projection objective lens of deep ultraviolet photoetching machines. By the adjustable vacuum sucker device, the problem that lenses, lens barrels and lens frames of different dimensions cannot be reliably absorbed and transported in the process of processing and assembling photoetching projection objective lenses is solved. The adjustable vacuum sucker device comprises an adaptive joint, an upper cover, a shell, a worm wheel, a worm screw, an adjusting handle, shift pins, a connecting rod and rubber suction nozzles. The three shift pins which are circumferentially and uniformly distributed are driven to rotate through the meshing driving of the worm wheel and the worm screw; and the shift pins shift the connecting rod to make the centrosymmetrical three rubber suction nozzles synchronously moved from the center to the periphery. The sucker device has a simple structure, steplessly adjustable suction ranges, large adjustment ranges and capability of self locking, and the rubber suction nozzles do not damage the surfaces of sucked workpieces. The sucker device can be used for sucking optics lenses and the suction of parts such as the lens frames and the like with annular end faces, has a simple structure, can be used for nondestructive clamping, is continuously adjustable, and can simultaneously suck the lenses and the lens frames.

Description

technical field [0001] The invention relates to the technical field of manufacturing and assembling the projection objective lens of a deep ultraviolet lithography machine, in particular to an adjustable vacuum chuck device that can be used for transporting lenses, lens barrels and frames of different sizes during the process of processing and assembling a projection objective lens for lithography. Background technique [0002] The manufacturing and assembly of lithography projection objective lens is a very precise and complex process, whether it is the fine grinding, polishing and testing of the lens, or the precision machining and testing of the frame, as well as the clamping of the lens and the frame during the assembly process, all need Frequently transport lenses and frames back and forth between different processing equipment and testing equipment. In this process, it must be strictly guaranteed that no damage will be caused to the optical surface of the lens and the ...
