Semiconductor laser alignment-based reflection type verticality detection system and method

Abstract

The invention relates to a semiconductor laser alignment-based reflection type verticality detection system and method. The system comprises a perforator which has an axially hollow structure shaped like an inverted T, an end part of the perforator corresponds to a surface of an arc object, a semiconductor laser device and a semitransparent mirror are arranged in an extension part perpendicular tothe end part, a side wall of the extension part is provided with a via hole, a circle center of the via hole and a center of the semitransparent mirror are positioned on the same horizontal line, a laser beam emitted via the semiconductor laser is split into first transmitted light and first reflected light after being transmitted to the semitransparent mirror, the first transmitted light is reflected to the semitransparent mirror after vertically irradiating onto the surface of the arc object after going through a transparent medium, the first transmitted light is again split into second transmitted light and second reflected light via the semitransparent mirror, the second reflected light irradiates on a mirror surface holophote positioned outside the perforator after running through avia hole, the mirror surface holophote corresponds to the via hole in terms of position, and the second reflected light is reflected to a CCD via the mirror surface holophote. The detection system andmethod disclosed in the invention can be used for verticality detection and positioning of the arc object.

Description

technical field [0001] The invention relates to a verticality detection system and method, in particular to a reflective verticality detection system and method based on semiconductor laser collimation applied in the industrial field. Background technique [0002] At this stage, the verticality detection of objects with arc surfaces is basically based on the experience of workers or the use of image processing to detect the verticality of arc objects with diffuse reflection and punch holes at fixed points. The former requires a lot of clinical practice experience for workers, and has high requirements for workers’ experience and physical condition at that time; while the latter involves a series of expensive components such as image processing (high-definition CCD cameras, conductive optical fibers, PCs, positioning devices, etc.), the cost Higher and more inconvenient to operate. Contents of the invention [0003] In view of the above problems, the purpose of the present...
