Description
Technical Field
The utility model relates to a sudden strain of a muscle survey appearance, especially a sudden strain of a muscle survey appearance is with measuring light source.
Background
In order to accurately measure the local size of a workpiece, the current flash measuring instrument needs to arrange illumination light sources at the top and bottom of the workpiece, and the workpiece clearly shows fine local features and complete contour lines by using illumination. However, for a part of the workpiece with steps in the height direction, the bottom light source cannot completely irradiate the edge position of the workpiece because part of the contour line of the workpiece is shielded by the large-size step surface; and the lens is only under the irradiation of the top light source then confuses the contour line of the upper end of the workpiece with the lower end plane easily, so that the flash detector cannot distinguish and complete the detection, and the detection effect on the workpiece is reduced. Therefore, the existing flash detector has the problems of low applicability and poor detection accuracy.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a dodge measuring light source for appearance. The method can effectively improve the applicability and the detection accuracy of the flash detector.
The technical scheme of the utility model: flash the survey light source for the appearance, include along the direction of height first light source and the second light source of illumination that arranges side by side, first light source's illumination is the slope light, second light source's illumination is the parallel light.
Among the aforesaid measurement light source for flash detector, still include the casing, first illumination light source and second illumination light source all are annular and distribute at the shells inner wall.
In the measurement light source for the flash measuring instrument, the housing is provided with a cover plate located outside the second illumination light source, the edge of the cover plate extends to the end of the second illumination light source, and the first illumination light source is located inside the cover plate in the horizontal direction.
In the measurement light source for the flash measuring instrument, the first illumination light source is composed of a plurality of first illumination subareas, and each first illumination subarea is provided with an interface connected with the control module.
In the measurement light source for the flash measuring instrument, the second illumination light source is composed of a plurality of second illumination subareas, and each second illumination subarea is provided with an interface connected with the control module.
In the measurement light source for the flash tester, the first illumination light source comprises a plurality of LED light sources, and a light homogenizing plate is arranged outside the LED light sources.
In the measurement light source for the flash detector, the second illumination light source is formed by arranging a plurality of light emitting diodes side by side.
Compared with the prior art, the utility model can illuminate the workpiece from the top through the oblique light formed by the first illuminating light source, thereby improving the definition of the surface of the workpiece; when the edge profile of the workpiece is shielded by the bottom, the second lighting source can be lifted and moved to the position flush with the profile surface of the workpiece, so that the profile surface and the bottom surface of the workpiece are distinguished by scattering of parallel light on the profile surface of the workpiece, a clear profile line can be formed on the vertical profile surface in the visual field of a lens, the measurement of the edge size of the workpiece by the flash measuring instrument is facilitated, and the applicability and the detection accuracy of the flash measuring instrument are improved; through being divided into a plurality of different illumination subareas with first illumination source and second illumination source for control module can carry out the independent control illumination to each illumination subarea through the interface, thereby makes the utility model discloses when carrying out size measurement to partial different shape work piece, can reduce the hindrance that shows the lines through closing partial illumination subarea, and then make the work piece profile that acquires that the flash measurement appearance can be accurate need be measured, further improved the suitability and the detection accuracy degree of flash measurement appearance. Therefore, the utility model discloses can effectively improve the suitability and the detection accuracy degree of sudden strain of a muscle survey appearance.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
The labels in the figures are: 1-first illumination source, 2-second illumination source, 3-housing, 301-cover plate.
Detailed Description
The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.
Examples are given. The measurement light source for the flash meter is configured as shown in fig. 1, and comprises a first illumination light source 1 and a second illumination light source 2 which are arranged side by side along the height direction, wherein the irradiation light of the first illumination light source 1 is oblique light, and the irradiation light of the second illumination light source 2 is parallel irradiation light with an angle of 0.
Still include casing 3, first illumination source 1 and second illumination source 2 all are the annular and distribute at 3 inner walls of casing, and the middle part of casing 3 is equipped with the opening with camera lens complex.
The housing 3 is provided with a cover plate 301 positioned outside the second illumination light source 2, the edge of the cover plate 301 extends to the end part of the second illumination light source 2, and the first illumination light source 1 is positioned inside the cover plate 301 in the horizontal direction.
The first illumination light source 1 is composed of a plurality of first illumination subareas, and each first illumination subarea is provided with an interface connected with a control module.
The second lighting source 2 is composed of a plurality of second lighting subareas, and each second lighting subarea is provided with an interface connected with the control module.
The first lighting source 1 comprises a plurality of LED light sources, and light homogenizing plates are arranged on the outer sides of the LED light sources.
The second illumination light source 2 is formed by arranging a plurality of light emitting diodes side by side.
The utility model discloses a theory of operation: the utility model discloses install on sudden strain of a muscle tester through elevating system when using. In a normal state, the surface of the workpiece is illuminated by the first illumination light source 1 through oblique light; when the work piece need throw light on at the edge, earlier remove measuring light source to the vertical face parallel and level each other of second lighting source 2 and work piece through elevating system, then send parallel light by second lighting source 2 and will shine the vertical face of work piece, make the work piece in the end angle department at edge forms the scattering and jets into measuring lens for can form a clear visible contour line in the camera lens field of vision, thereby improve the size measurement accuracy who dodges the measuring instrument. When the contour line of the lens detection of the workpiece is too disordered and cannot be clearly obtained due to the special-shaped structure, a user can close other lighting partitions according to the position of the required contour line, so that the interference of the lens during detection can be reduced, and the detection accuracy of the flash detector is further improved; meanwhile, segregation synthesis can be performed on software by using different photos of partitioned illumination, and details of the workpiece in the height direction of the workpiece are highlighted.
