At present, for manufacturing and the defect situation of confirming printed circuit board (PCB), generally need to use camera and display unit to check, the printed circuit board (PCB) zone that will check with camera, and be shown enlarged on the display unit, check to find the bad position (as: failure welding, film come off etc.) on the printed circuit board (PCB).But common available light can not reach the requirement of brightness far away, and is especially when carrying out high-speed image sampling, high to the time for exposure requirement, so light source need be set in testing fixture.If but with the light direct irradiation of ordinary light source on printed circuit board (PCB), take with camera then, then can be because of factors such as circuit board surface situations, make its surperficial light inhomogeneous, produce some and do not wish the dazzle that exists, cause the circuit board image that collects untrue, thereby influence is further analyzed to the defective of printed circuit board (PCB).
For the problem of light, under the situation that color is determined, as long as consideration is light intensity and quality problems.Light intensity is that luminosity and the quantity by light source decides.And the quality of light mainly is meant direct light and scattered light.Adopt direct light than the solid shape that is easier to show the person taken picture, make take the photograph image have gray scale and contrast preferably.Adopt scattered light can not form tangible sensitive surface and shadow surface, do not have tangible projection, light effects is more flat soft, improves the details expressive ability of picture, prevents scanning leakage.Industrial light supply apparatus on the market and fail to cooperate effectively and utilize direct light and scattered light now to collect real circuit board image.
Chinese invention patent specification (publication number CN1804547A, open day on July 19th, 2006) a kind of automatic optical detection device is disclosed, this device is by installing the light guide member between luminous component and PCB, be used to assemble from PCB and take that the district departs from and the light that will lose and this converging light guiding PCB taken the district, light loss when detecting the PCB pattern with inhibition obtains uniform brightness.But the structure relative complex of this device has increased production cost.
The utility model content
For overcoming the problem of the deficiencies in the prior art and existence, it is a kind of simple in structure that the utility model provides, and is easy to mounting or dismounting, and the optically focused lamp body that can control separately and astigmatic lamp body are to avoid the industrial light supply apparatus of problems such as over-exposed or contrast deficiency.
The utility model is achieved through the following technical solutions: a kind of industrial light supply apparatus, and comprise lampshade and be arranged at the interior lamp body of lampshade, described lampshade is toroidal, and described lamp body comprises the astigmatic lamp body and the optically focused lamp body of separate setting; Along being provided with the annular installation position that is used to install astigmatic lamp body, also being provided with a stairstepping on this lampshade inwall and circularizing platform and be used to install the optically focused lamp body in the opening of described lampshade.Described astigmatic lamp body comprises independently pcb board, is installed on astigmatic LED bulb and power line on the pcb board; Described optically focused lamp body comprises independently pcb board, is installed on optically focused LED bulb and power line on the pcb board.Described lampshade is provided with screwed hole and is used to install astigmatic lamp body and optically focused lamp body, and this lampshade and optically focused lamp body are for removably connecting.
Further, described optically focused LED bulb is formed slopely 0～15 ° angle towards the axle center of optically focused lamp body.
Further, described lampshade is provided with watch window and is used to observe the projection situation of light and the plate face situation of visualization sample to be tested.Described lampshade is provided with the power line outlet of cable hole as astigmatic lamp body.Described lampshade is provided with installing hole and is used to install and fix this light supply apparatus.
Compared with the prior art, the utility model is simple in structure, is easy to mounting or dismounting, has the optically focused lamp body and the astigmatic lamp body of independent control.When the utility model is applied to the PCB outward appearance and detects, can help suppressing the supersaturation of metallic region by singly opening astigmatic lamp body, the zone of high antiradar reflectivity can be reflected in simultaneously take the photograph image on, avoid over-exposed cause unintelligible; The optically focused lamp body then can be used for observing dark blind hole and concavo-convex scar, prevents the problem that the contrast deficiency causes; By regulating the brightness of scattered light and direct light, both are used, and the dazzle that produces in the time of can effectively eliminating imaging obtains real PCB image.
