Abstract
The utility model relates to a bidirectional scratch detection structure, which comprises a camera component and a light source, wherein an included angle is formed between the light source and a horizontal extension surface of the surface of a product; the light source have a casing, the casing in be provided with a plurality of luminous bodies, the luminous body use the central axis of casing as the even symmetric distribution of symmetry axis in the casing bottom, the luminous body inwards shines from the both sides of the central axis of casing downwards, has the contained angle between the central axis of the direction of shining of luminous body and casing. The utility model discloses a product is shone to the light source of a plurality of directions, can present the ascending mar of a plurality of directions, has improved the suitability that uses the quality control machine product, satisfies the ascending mar detection of single light source solution both directions.
Description
Technical Field
The utility model belongs to the technical field of the image detection technique and specifically relates to a two-way mar detects structure.
Background
The conventional scratch imaging mode and structure can only present scratches in one direction, and the scratches in the working direction and the scratches perpendicular to the working direction cannot be presented at the same time. The scratch is strip-shaped, light is irradiated on the scratch from one direction in parallel to present diffuse reflection in one direction, and diffuse reflection light rays which cannot be formed by the scratch enter a camera due to no light in the other direction; the scratch can be divided into a longitudinal scratch and a transverse scratch, and the light source irradiated in a single direction only can present the scratch in a single direction, so that light rays which should be reflected to the camera originally are reflected to other places due to the fact that the light path direction is changed, and imaging on the camera is not uniform.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: a bidirectional scratch detection structure is provided, which solves the detection of thin and shallow scratches in multiple directions in a visible light image.
The utility model provides a technical scheme that its technical problem adopted is: a bidirectional scratch detection structure comprises a camera component and a light source, wherein an included angle is formed between the light source and a horizontal extension surface of the surface of a product; the light source have a casing, the casing in be provided with a plurality of luminous bodies, the luminous body use the central axis of casing as the even symmetric distribution of symmetry axis in the casing bottom, the luminous body inwards shines from the both sides of the central axis of casing downwards, has the contained angle between the central axis of the direction of shining of luminous body and casing.
Further, the product place on the transmission belt, the central axis of light source is 15 with the contained angle of belt.
Furthermore, the luminous body of the utility model is a LED light bead.
Still further say, the direction of illumination of LED light pearl be 45 jiaos of symmetry and set up the both sides at the central axis of casing.
The utility model discloses a parallel light of working direction is not only jeted into to the object to the structure, also jeted into perpendicular to working direction's parallel light to the object simultaneously, and the mar on object surface obtains coming from two ascending parallel lights in direction, can send diffuse light to two directions, and these light can be gathered to the camera.
The beneficial effects of the utility model are that, solved the defect that exists among the background art, the light source through a plurality of directions shines the product, can present the ascending mar of a plurality of directions, has improved the suitability that uses the quality control machine product, satisfies the single light source and solves the ascending mar detection of both directions.
Drawings
Fig. 1 is a schematic structural diagram of the present invention;
fig. 2 is a schematic structural diagram of the light source of the present invention;
in the figure: 1. a camera; 2. a light source; 3. a belt; 4. a housing; 5. a light bead; 6. a central axis.
Detailed Description
The invention will now be described in further detail with reference to the drawings and preferred embodiments. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.
As shown in fig. 1, a bi-directional scratch detection structure includes a camera 1 assembly and a light source 2, wherein an included angle is formed between the light source 2 and a horizontal extension plane of a product surface; the product is placed on the conveying belt 3, and the included angle between the central axis 6 of the light source and the belt 3 is 15 degrees.
The light source 2 is provided with a shell 4, a plurality of luminophors are arranged in the shell 4, the luminophors are large-particle LED light beads 5, and the light beads shown in figure 2 are cylindrical. The luminous bodies are uniformly and symmetrically distributed at the bottom of the shell by taking the central axis of the shell as a symmetry axis, the irradiation directions of the LED light beads are symmetrically arranged at two sides of the central axis of the shell at an angle of 45 degrees, and the luminous bodies irradiate inwards and downwards from two sides of the central axis of the shell.
Because the mar has the directionality, the light source that the individual direction shines can only present the unilateral mar, this detection structure has analyzed the characteristics of mar, has designed a set of oblique direction lamp pearl and has shone, uses the imaging structure that the low angle shines in the machinery, has solved the thin shallow mar of a plurality of directions in the visible light image, and the mar of individual direction can only be imaged to general imaging structure.
While the foregoing is directed to embodiments of the present invention, other and further embodiments of the invention may be devised without departing from the basic scope thereof, and the scope thereof is determined by the claims that follow.
