Abstract

The utility model discloses an optical detection structure for preventing optical interference, which comprises a shell, wherein the shell is sealed, a black shading paint layer is arranged in the inner wall of the shell, and a detection camera is arranged at the center of the upper end of the shell; a spherical reflector is further arranged on the inner wall of one side of the middle upper part of the shell, light source lamps are further arranged on two sides of the detection camera, ground glass is further arranged on the middle upper part of the shell, and a notch is formed in the position, corresponding to the detection camera, of the ground glass; still be equipped with the detection anchor clamps of taking the door plant on the well lower part of casing, the utility model has the advantages that the rate is unanimous, the utility model has the advantages that: the black shading paint layer is arranged inside the shell, so that external light interference is effectively prevented, measuring errors are reduced, meanwhile, the combination of the spherical reflector and the ground glass is adopted at the light source, the light source is uniformly distributed on the ground glass after the spherical reflector reflects away with different reflectivity, the ground glass disperses the light source again, and the measuring precision of an object to be measured is higher.

Description

Light detection structure for preventing light interference
Technical Field
The utility model relates to a part detection area, a part light detection device specifically says so.
Background
Automobile door plant or interior trim part need carry out the camera before dispatching from the factory and shoot and detect, among the prior art, the environment of shooing in workshop inside can receive external factors to interfere, for example, in sunny day or rainy day, can produce certain illumination influence to the environment of shooing, consequently, can influence the authenticity that the detection camera was shot, and such result of shooing can certainly influence the measuring result who detects the object, and among the prior art, the light source lamp is only the lantern formula and shines, such light source still can make the local overexposure of object to be measured under external light source's influence, the measuring result of object to be measured has been influenced more.
SUMMERY OF THE UTILITY MODEL
In order to solve the above problem, the utility model discloses a have anti external factors to disturb to and the even optical detection device of light source.
The specific technical scheme is as follows:
a light detection structure for preventing light interference comprises a shell, wherein the shell is arranged in a sealing manner, a black shading paint layer is arranged in the inner wall of the shell, and a detection camera is arranged at the center of the upper end of the shell; a spherical reflector is further arranged on the inner wall of one side of the middle upper part of the shell, light source lamps are further arranged on two sides of the detection camera, output light of the light source lamps irradiates on the spherical reflector, ground glass is further arranged on the middle upper part of the shell, and notches are formed in positions, corresponding to the detection camera, of the ground glass; and a detection clamp with a door plate is also arranged on the middle lower part of the shell.
The center of the inspection fixture is facing the inspection camera.
The spherical reflectors are uniformly distributed on four inner wall surfaces of the shell, and the number of the light source lamps corresponds to the number of the spherical reflectors.
The curvatures of the four spherical reflectors are consistent.
The utility model has the advantages that: the black shading paint layer is arranged inside the shell, so that external light interference is effectively prevented, measuring errors are reduced, meanwhile, the combination of the spherical reflector and the ground glass is adopted at the light source, the light source is uniformly distributed on the ground glass after the spherical reflector reflects away with different reflectivity, the ground glass disperses the light source again, and the measuring precision of an object to be measured is higher.
Drawings
FIG. 1 is a schematic structural view of the present invention;
FIG. 2 is a top view of FIG. 1;
FIG. 3 is a schematic structural diagram of a second embodiment;
fig. 4 is a top view of fig. 3.
Detailed Description
The utility model is described in detail with reference to the drawings, as shown in the figures, the light detection structure for preventing light interference comprises a shell 1, the shell is arranged in a sealing way, a black shading paint layer 2 is arranged in the inner wall of the shell, and a detection camera 3 is arranged at the center of the upper end of the shell; a spherical reflector 4 is further arranged on the inner wall of one side of the middle upper part of the shell, light source lamps 5 are further arranged on two sides of the detection camera, output light L of the light source lamps irradiates on the spherical reflector 4, ground glass 6 is further arranged on the middle upper part of the shell, and notches 601 are formed in positions, corresponding to the detection camera, of the ground glass; a detection clamp 7 with a door plate is also arranged on the middle lower part of the shell.
The center of the inspection jig 7 is facing the inspection camera 3.
The spherical reflectors 4 are uniformly distributed on four inner wall surfaces of the shell 1, and the number of the light source lamps 5 corresponds to the number of the spherical reflectors 4.
The curvatures of the four spherical reflectors are consistent.
The utility model discloses a theory of operation is: when beginning to detect, the light that the light source lamp jetted out shines on the spherical reflector with different angles, as shown by the route of L in the picture, the light that the spherical reflector will shine into with different reflectivity simultaneously reflects away again to shine on ground glass, compare in current fluorescent tube and shine, the light radiation area through the spherical reflector reflection is wider, and the light of shining on the article that awaits measuring simultaneously is more even.
The second embodiment is as follows:
the utility model discloses further disclose a light detection structure with convex lens, lie in with the difference of embodiment one: the outer side of the light source lamp is further provided with a convex lens, the convex lens is fixed in the shell through a hanging rod, light irradiated out of the light source lamp can be irradiated on the spherical reflector in a relatively parallel mode through the structure with the convex lens, meanwhile, the light irradiated on the spherical reflector is relatively concentrated, meanwhile, the light range reflected out through the spherical reflector is small, and finally, the light passing through the ground glass is smaller than the structure range without the convex lens, but because the structural size of the door plate does not need a wide irradiation area, the beneficial effect brought by the smaller range is that the irradiated brightness is higher, and the object to be measured can be distinguished under the completely black environment in the shell more conveniently.
