Abstract
The invention relates to a scattering linear light detection device, which comprises a condensing unit group, wherein the condensing unit group comprises a first condensing unit group and a detection camera which is matched with the condensing unit group to use. The first condensing unit group is characterized in that the condensing unit group comprises a light source, a scattering diaphragm and a condensing lens. The scattering linear light detection device changes the injection direction of light rays by adding the scattering diaphragm, and can excellently show defects in various directions in a plane.
Description
Technical field
The present invention relates to the linear light source detection device of a kind of scattering.
Background technology
Current line scan camera important light source used is line source, because the shooting angle of line source is more fixing.As shown in Figure 1, First Line light source 1 comprises, light source 11 and light focusing unit 12, and light is vertically injected light focusing unit 12 by light source 11, makes existing line source have certain limitation.As shown in Figure 2, for the device utilizing existing line source to detect screen, comprise First Line light source 1, and the detection camera 7 for detecting, First Line light source 1 forms the first light belt 4 in screen surface 3 to be detected, simultaneously detection camera 7 forms sweep trace 6, if cut or foreign matter parallel with sweep trace 6, scanning camera 7 can not detect foreign matter.If add one with the second line source 2 of First Line light source 1 vertical incidence, but the areas imaging of line scan camera cannot all throw light on by this second line source 2, so cannot use in reality.
Because above-mentioned defect, the design people, actively in addition research and innovation, the linear light source detection device of the scattering to founding a kind of new structure, makes it have more value in industry.
Summary of the invention
For solving the problems of the technologies described above, the object of this invention is to provide the linear light source detection device of a kind of scattering.
Technical scheme of the present invention is as follows:
The linear light source detection device of a kind of scattering, comprise light focusing unit group, described light focusing unit group comprises the first light focusing unit group, and with described light focusing unit group with the use of a detection camera, described first optically focused is characterized in that: described light focusing unit group is made up of light source, scattering diaphragm, shell and optically focused Lens.
