Abstract
The invention provides a directional light source for visual inspection. The directional light source comprises a housing, at least one group of light source units arranged in the housing, and a sinking part formed in the upper surface of the housing and used for accommodating a workpiece to be inspected, wherein light-transmitting plates connected with the housing are arranged at two end parts and two side edges of the sinking part; the light source units are arranged at end parts or the side part of the sinking part; and each light source unit comprises a circuit board, LED lamp beads arranged on the circuit board and a condensing lens arranged on the circuit board and in front of the LED lamp beads. The LED lamp beads in the light source units at the periphery of the sinking part which accommodates the workpiece to be inspected give out light toward the inner side, and a high-brightness light source forms orientation within a certain range after being condensed by the condensing lenses in front of the LED lamp beads and is uniformly projected onto the inspected workpiece, so that various defects and dust on the surface of the workpiece can be clearly shot, and the purpose of efficiently and accurately detecting optical components is achieved.
Description
Technical field
The present invention relates to a kind of directivity vision-based detection light source being used for LED technology detecting printing opacity workpiece.
Background technology
Application along with automatization and intellectual technology and equipment, vision-based detection is increasingly becoming the important composition part of automatic intelligent machine and equipment, be equivalent to load onto eyes to the machine of automatization, more effectively implement and complete work, but automatically detecting optics, such as liquid crystal display module, during the light transparent member such as mobile phone optical glass cover plate, existing light source often can not meet requirement, surface and number of drawbacks are often difficult to be taken pictures discovery by industrial camera, and vision software is also just difficult to analyze and identify.
Summary of the invention
In order to solve the deficiencies in the prior art part, it is an object of the invention to provide a kind of directivity vision-based detection light source being arranged around light source cell at workpiece to be checked；The light that LED lamp bead produces, after light-collecting lens, obtains the light source that the rectilinearity of high brightness is good, and makes light source form certain sensing, be conducive to the image that detection industrial camera photographs complete display to carry out processing and analyzing.
For achieving the above object, the technical solution used in the present invention is: a kind of directivity vision-based detection light source, including shell, least one set is located at the light source cell in shell, being located in upper surface of outer cover for placing the sinking portion of workpiece to be checked, two ends in sinking portion and dual-side are equipped with the light-passing board being connected with shell；Described light source cell is positioned at end or the side in sinking portion；Wherein light source cell includes circuit board, is located at the LED lamp bead on circuit board, is located on circuit board and is positioned at the light-collecting lens in LED lamp bead front.
Described light source cell is positioned at the space that shell encloses with light-passing board.
Described light source unit is four groups, lays respectively at two sides and the both ends in sinking portion, exposes in sinking portion after the light therethrough light-passing board that light source cell is launched.
Light-collecting lens on light source cell is positioned at the rear of light-passing board.
The Advantageous Effects of the present invention: the LED lamp bead being installed in the light source cell of the sinking portion surrounding placing workpiece to be checked is luminous to the inside, a range of sensing is formed by the higher source luminance after being installed in the light-collecting lens optically focused in LED lamp bead front, uniformly it is incident upon above checked workpiece, various defects and the dust of surface of the work can be clearly photographed, reach efficiently and accurately to detect the purpose of optics.
