Coaxial revolving photomasking device for laser processing

Abstract

The invention relates to a coaxial revolving photomasking device for laser processing. The device comprises a marble platform and a photomasking device revolving table which is arranged below the marble platform, and is characterized in that: the revolving table comprises a rotating shaft, a photomasking device mounting base and a photomasking plate; the lower surface of the marble platform is provided with a rotating motor; a power output end of the rotating motor is connected with the rotating shaft; the lower end of the rotating shaft is provided with a rotating work table; the photomasking device mounting base is arranged on the rotating shaft through a rolling shaft, and is provided with a three-dimensional adjusting sliding table; the photomasking plate is fixed on the three-dimensional adjusting sliding table; the inner ring of a rolling bearing is connected with the rotating shaft, and the outer ring of the rolling bearing is connected with the photomasking device mounting base through a bearing connecting frame; and both the photomasking device revolving table and the work table can rotate around the rotating shaft. The device has a simple structure, is accurate in repeated positioning and easy to adjust and maintain, and is widely applicable to the field of laser processing.

Description

technical field [0001] The invention relates to a masking device for controlling the scanning processing range of a laser beam, in particular to a coaxially rotating laser masking device, which belongs to the technical field of laser processing. Background technique [0002] During the laser beam scanning process, it is usually necessary to control the scanning range of the laser beam and protect other non-working area components on the equipment from laser damage. In engineering, more mechanical methods are usually used to realize this function through light shading, which involves the aforementioned light shading device for laser processing. Since the masking device is often close to the workpiece, the workpiece debris and smoke generated during laser processing are easily attached to the masking device. The masking device itself will be damaged due to long-term exposure to the laser beam, which will affect the processing of the workpiece. Quality, so the shading device o...

AI Technical Summary

Problems solved by technology

This design better solves the problem of difficult cleaning and maintenance of the previous light masking device, but since the rotary axis of the light masking device and the rotating shaft of the worktable are not on the same axis, it requires high assembly accuracy and machining accuracy of parts. Moreover, the offset that needs to be adjusted when the shading device is in the internal working state of the equipment cannot be intuitively reflected after it is unscrewed, and the positioning is difficult during adjustment, which requires high experience for the adjustment personnel
