High-precision optical axis and multi-optical axis parallelism adjustment method

Abstract

The invention discloses a high-precision optical axis and multi-optical axis parallelism adjustment method, which comprises the following steps of: S1, moving a fixed plate to an adjustment position at one end of an optical axis; s2, pulling a cross rod to drive an adjusting cylinder to adjust the position at the other end of the optical axis; s3, light rays emitted by a light source are compared with the center position of one optical axis, it is guaranteed that reflected light rays return and coincide, and a reference position is formed through calibration; s4, rotating the direction of the adjusting cylinder, aligning the light source to another optical axis, and repeatedly calibrating to form a calibration position; s5, irradiating the light onto a first reflective mirror through an optical axis to form reference light; s6, forming an adjustment light ray; s7, receiving the adjustment light for observation and recording; s8, the position of the other optical axis is adjusted, the light is correspondingly adjusted, coincidence is guaranteed, and surface calibration light is formed; and S9, parallelism adjustment can be completed after two times of calibration, so that the convenience and the stability of use can be greatly improved, and the accuracy and the high efficiency of adjustment are ensured.

Description

technical field [0001] The invention relates to the technical field of parallelism of optical axes, in particular to a method for adjusting the parallelism of high-precision optical axes and multiple optical axes. Background technique [0002] The parallelism of the optical axis is an important parameter of precision laser processing equipment with a dual optical axis optical system. In a laser processing system with a video monitoring system and a laser ranging module, the visual axis of the video monitoring system and the light The parallelism between the main laser beam and the laser emitting optical axis is the key to ensure that the main laser beam accurately acts on the processing target along the tracking measurement axis, and must be guaranteed first in design, processing, assembly and use. [0003] In the parallelism adjustment of the optical axis and multiple optical axes, most of the operations are performed using a relatively complex principle structure, which is...

Problems solved by technology

[0003] In the parallelism adjustment of the optical axis and multiple optical axes, most of the operations are performed using a relatively complex principle structure, which is not conducive to continuous calibration on the optical axis, and the operation is difficult, and the accumulation of errors is large, which affects Adjustment accuracy, and the existing adjustment method can only perform alignment calibration at a fixed position, and cannot be reversed, which affects the convenience and accuracy of operation, and needs to be improved
