Description

Optical sensor for iron casting detection

Technical Field

The utility model relates to the technical field of iron casting production equipment, in particular to an optical sensor for iron casting detection.

Background

Three-dimensional scanning is a common means of performing dimensional checks during the development of iron castings. The working principle of three-dimensional scanning is that a C-Track camera simultaneously collects positioning target points, the position of a probe and the environment of the probe are determined by a triangulation method through software to construct a reference coordinate system, patterns of the positioning target points observable by the C-Track camera are the same as those of a handheld three-dimensional laser scanner, the surface data collection of the iron casting is completed by identifying laser lines projected to the surface of the iron casting, the three-dimensional graph construction is carried out according to dynamically identified data, the three-dimensional graph is matched and compared with a three-dimensional drawing, and the size analysis is carried out.

The positioning of the target point is the key to the success or failure of the three-dimensional scanning detection. The C-Track camera needs to establish a reference coordinate system according to the collected positioning target point information. The positioning target point is a highly reflective optical sensitive original piece, and is required to be fixed on the scanning surface of the iron casting when in use, and the highly reflective surface of the positioning target point needs to be over against the C-Track camera, so that the C-Track camera can be clearly identified; in order to ensure the reliability of the detection result, at least 4 target positioning points should be fixed on the iron casting to be detected, and the more the number of the positioning target points is, the better the positioning target points are, but the maximum limit cannot be exceeded, and the positioning target points are distributed irregularly; when overturning, the target positioning point should be fixed and cannot move.

The existing positioning target point is a magnetic protection positioning target point, a high-reflection optical sensitive piece is cast on a magnet to form a whole, and the high-reflection optical sensitive piece is adsorbed on the surface of the iron casting through the magnet to be fixed when the high-reflection optical sensitive piece is used. Due to the optical sensitivity of the positioning target point, the surface of the target point is required to be clean and intact when the positioning target point is used, and in the actual use process, the high-reflection part of the positioning target point is often damaged due to collision and cannot be used continuously; or the magnet adsorbs steel shots and iron filings to cause unstable fixation, infirm adhesion and the like, and a new positioning target point needs to be replaced; sometimes, the iron filings adsorbed by the magnet can scratch the high-reflection part, so that the magnet cannot be used continuously. Therefore, the technical problem to be solved by the utility model is how to design an optical sensing element for iron casting detection, which has long service life and is convenient for cleaning impurities.
