Optical device for detecting appearance of magnetic circuit materials

Abstract

The invention discloses an optical device for detecting the appearance of magnetic circuit materials. The optical device comprises an image processor. The image processor is connected with a camera, an optical imaging mechanism is arranged at the front of a lens of the camera and comprises reflective mirrors, a backlight plate and a beam splitter, the reflective mirrors are arranged on the periphery of a to-be-detected object, the backlight plate is used for providing light sources to the reflective mirrors, the beam splitter is used for refracting light reflected by the reflective mirrors tothe lens of the camera, and light beams emitted by the beam splitter are coaxial light rays parallel to the optical axis of the camera; a hollow-square-shaped element for changing light ray refractiveindexes is further arranged between the beam splitter and the reflective mirrors. The optical device has the advantages that the reflective mirrors and the beam splitter are used, and accordingly five portions of the to-be-detected object can be simultaneously photographed by the single camera; complement regions of the innermost 'squares' and peripheral 'squares' of 'hollow-square shapes' can have different refractive indexes by the aid of the hollow-square-shaped element, field depth gaps can be computed by the aid of the difference between the refractive indexes, and accordingly the problem of inconsistency of field depths of existing to-be-detected objects can be solved.

Description

technical field [0001] The invention relates to the field of detection equipment, in particular to an optical device for detecting the appearance of magnetic circuit materials. Background technique [0002] In the prior art, for the detection of the magnetic circuit material (object to be tested), it is necessary to set up 5 cameras around the magnetic circuit and the magnetic circuit material to take pictures of the 5 surfaces of the magnetic circuit material respectively, and transmit the captured pictures through IO to the image processor for corresponding processing. The above-mentioned processing process cannot solve the problem of inconsistency in the depth of field of the object to be measured, and at the same time, multiple cameras also increase the cost. Contents of the invention [0003] In order to overcome the above-mentioned shortcomings, the object of the present invention is to provide an optical detection device for photographing five surfaces of the objec...
