Abstract
The utility model provides online light source unit equipment for the exterior appearance quality detection in the electronic production and SMT (surface mounting technology) fields. A red LED luminous unit, a green LED luminous unit and a blue LED luminous unit are arranged from high to low in a shade body, the luminous surfaces of all the LED luminous units are continuous and even luminous surfaces which are in a cone side shape, the luminous direction is toward the inside of the shade body, and the angles of the cone side shapes of all the LED luminous assembly increase from top to down. The utility model provides a reliable and stable online light source unit equipment for the exterior appearance quality detection of tiny products in the electronic production and SMT (surface mounting technology) fields and illuminates the surface of objects to be detected at different heights and from different angles to ensure that a vidicon obtains richer information of the change of surface of objects to be detected; the illumination range is wider and the brightness is even, which provides wider shooting range for the vidicon; the utility model is radiationless and maintenance free and has low power consumption, long service life and environmental protection.
Description
Technical field
The utility model relates to a kind of online combination of light sources device, especially relates to the online combination of light sources device that a kind of exterior quality that is used for electronics production, SMT surface mount field detects.
Background technology
Current, in the whole process of production in fields such as electronics production, SMT surface mount, all need the electronic component that relates to, paster etc. are carried out the Quality Detection and the quality management and control of outward appearance, check by the irradiation of light source whether element, paster surface have defectives such as foreign matter or cut, get rid of sub-standard element, paster in advance, avoid the waste that the later stage does over again.The light source that uses is common light source at present, as common light sources such as fluorescent lamp, incandescent lamp, Halogen lamp LEDs, is radiated at surfaces such as element, paster, observes by video camera again.There are various shortcomings in these ordinary light sources, as brightness irregularities, produce high heat, and high power consumption etc. influence the effect when detecting, and become the production capacity bottleneck of whole process of production.
The utility model content
Technical problem to be solved in the utility model is: for the small product appearance Quality Detection in field such as electronics production, SMT surface mount provide a kind of reliable and stable online combination of light sources device.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of online combination of light sources device, the exterior quality that is used for electronics production, SMT surface mount field detects, in cover body, be disposed with luminous group of red LED, luminous group of green LED, luminous group of blue led from high to low, the light-emitting area that each LED is luminous group is the continuous homogeneous light emitting area that is the frustum cone side shape, and light emission direction is towards the cover body inboard, and the angle of truncated cone-shaped side that luminous group of each LED is increases from high to low successively.
Wherein, described cover body is made up of lid, mounting cup, installing ring and end cover; Mounting cup is upper and lower opening " protruding " font ducted body, luminous group of red LED be arranged at the installation on mounting cup top poor in, lid is arranged at the mounting cup top; Luminous group of green LED is set in the mounting groove of mounting cup bottom; Installing ring is the annular of hollow, is arranged at the mounting cup bottom; In end cover mounting groove luminous group of blue led is set, end cover is connected fixing with installing ring.
Wherein, the circuit by computer software control stroboscopic function is connected for luminous group with each LED.
The utility model utilizes optical reflection law and diffuse reflection principle, use multi-group light-emitting LED diode: three kinds of colors of red, green, blue, illuminate the detected object surface by different height and angle, utilize optics light diffuse reflection principle, make video camera obtain abundanter detected object surface change information.Be tending towards plane branch for the detected object surface, light is by the reflection of body surface, and most of light is gathered by video camera, is converted to natural image; Be tending towards chamfered portion for the detected object surface, reflect a large amount of blue rays and gathered by video camera, the surface that is tending towards the inclined-plane is revealed as blueness.
The beneficial effects of the utility model are: use multi-group light-emitting LED diode to illuminate the detected object surface by different height and angle, make video camera obtain abundanter detected object surface change information; Illumination range is bigger, and brightness is even, provides bigger coverage to camera; Computer software control realizes the light source stroboscopic, has low in energy consumption, long service life, radiationless, the non-maintaining characteristics of environmental protection.

The specific embodiment
As shown in Figures 1 and 2, Fig. 1 is the stereogram of the online combination of light sources device of the utility model preferred embodiment, and Fig. 2 is its cutaway view, and this preferred embodiment is applied to the online detection of SMT surface mount exterior quality.Described online combination of light sources device comprises a cover body, and described cover body is made up of lid 1, mounting cup 3, installing ring 5 and end cover 7, in the installation that red LED is arranged at mounting cup 3 tops for luminous group 2 is pickled with grains or in wine; Lid 1 is arranged at mounting cup 3 tops; Luminous group 4 of green LED is set in the mounting groove of mounting cup bottom; Installing ring 5 is arranged at mounting cup 3 bottoms; Cover the end of at luminous group 6 of blue led is set in 7 mounting grooves, end cover 7 is connected with installing ring 5 fixes.
As shown in Figure 3, it is a schematic diagram of the present utility model.Be tending towards the part on plane for the detected object surface, the light that light supply apparatus sent that comprises Red Green Blue is the minute surface reflection by the reflection on surface, and most of light is gathered by video camera, is converted to natural image; Be tending towards chamfered portion for the detected object surface, what taken place is reflected into diffuse reflection, distributing position and distribution angle by three kinds of colors of red, green, blue are determined, the big more position of (convex-concave) degree that tilts, the side-irradiation that blue led is luminous group is many more, chamfered portion reflects a large amount of blue rays and is gathered by video camera, and the surface that therefore is tending towards the inclined-plane shows as blueness.
