Abstract
The utility model relates to a light source device applicable to appearance machine verification of a printed circuit board and is characterized in that: the light source device comprises an aluminum base plate with light-emitting diodes (LEDs) which are uniformly distributed. A strip-shaped CCD (Charge Coupled Device) capturing window is arranged on the aluminum base plate; and a diffusion plate for filtering an LED light source is mounted at the side of the distribution face of the LED light-emitting diodes of the aluminum base plate. Compared with the existing light source of the fluorescent lamp, the light source device multiplies the light intensity of the light source for several times but the softness of the light source is unchanged, therefore, the detection speed can be improved for several times and the capacity is improved. Meanwhile, the service life of the light source is greatly prolonged, and the service life of the light source is improved from one month to more than 4-5 years. Furthermore, the LED light source consists of a plurality of small particular LED lamps, so that the angle and the shape of the light source device can be randomly designed and the plasticity is very strong.
Description
Technical field
The utility model relates to light supply apparatus, especially a kind of light supply apparatus that is applicable to the machine examination of printed substrate outward appearance.
Background technology
As everyone knows, all electric equipments or control system all want the application of printed wiring board, and for guaranteeing wiring board stability and the life-span in use, printed substrate all need carry out outward appearance and detect before dispatching from the factory, and underproof wiring board is selected scrapped or repair.At present, the printed substrate outward appearance detects normally seized printed substrate placed carries out under the fluorescent tube light source, mainly adopts dual mode, and a kind of is to adopt visual inspection, and another kind is the machine examination of adopting the automatic shape inspection machine to carry out.But these two kinds of modes all have the part defective:
One, for visual inspection, its defective is bigger to people's dependence, and speed is slow, and quality is unstable.In addition, long eyesight and cervical vertebra to the people exerts an influence the working time.
Two, for machine examination; For the authenticity of image color, normally seized printed substrate is placed and carry out under the fluorescent tube light source, the brightness of fluorescent tube light source is lower usually; And brightness can directly influence the quality of machine examination image information acquisition, and then influence detects effect.
The utility model content
The utility model technical problem to be solved is the deficiency that remedies above-mentioned prior art, and a kind of light supply apparatus that is applicable to the machine examination of printed substrate outward appearance is provided.
The utility model solves through following technical scheme.
This characteristics of the light supply apparatus of printed substrate outward appearance machine examination that are applicable to are:
Comprise and arrange the aluminium base that is evenly equipped with the LED luminous tube, be axially arranged with bar shaped CCD picked-up window on the aluminium base;
The said aluminium base back side is spaced and is connected with fin;
The LED luminous tube of said aluminium base divides the cloth cover side to be covered with the diffuser plate that can filter led light source.
The technical problem of the utility model solves through following further technical scheme.
Said aluminium base is a semicircular arc structure aluminium base.
Said aluminium base is surrounded by some aluminium base stripe board.
The utility model beneficial effect compared with prior art is:
This light supply apparatus of printed substrate outward appearance machine examination that is applicable to is compared with existing fluorescent tube light source, make light-source brightness increase several times, and the soften of light source does not become.Like this, can significantly improve detection speed, improve production capacity.Simultaneously, light source life extends greatly, brings up to more than 4～5 years by original one month.In addition, because the light source of this wiring board appearance inspection machine light supply apparatus is made up of a lot of granule LED lamps, so can design the angle and the shape of light source arbitrarily, plasticity is very strong.
The utility model is applicable to that the concrete structure of the light supply apparatus of printed substrate outward appearance machine examination is provided by following accompanying drawing and embodiment in detail.
Description of drawings
Accompanying drawing is the light supply apparatus structural representation that is applicable to the machine examination of printed substrate outward appearance.
The specific embodiment
Can be clear that from accompanying drawing this is a kind of light supply apparatus that is applicable to the machine examination of printed substrate outward appearance with semicircular arc plane of illumination; The semicircular arc structure aluminium base 2 that surrounds by some bar shaped aluminium bases 1; Semicircular arc structure aluminium base 2 intrados are arranged and are evenly equipped with LED luminous tube 3, and semicircular arc structure aluminium base 2 is provided with bar shaped CCD picked-up window 4.Semicircular arc structure aluminium base 2 extrados are spaced and are connected with fin 5; 3 fens cloth cover sides of the LED luminous tube of semicircular arc structure aluminium base 2 are equipped with the diffuser plate 6 that can filter led light source.
Be distributed in the LED luminous tube 3 of semicircular arc structure aluminium base 2 intrados; Can enlarge surface of light source and light-source brightness; The heat sink 5 that is connected semicircular arc structure aluminium base 2 extrados can satisfy the heat radiation requirement of LED luminous tube 3 operations; The diffuser plate 6 that covers on semicircular arc structure aluminium base 2 intrados can detect the information pickup requirement to satisfy CCD to the printed substrate outward appearance with becoming evenly soft after the filtration of LED luminous tube 3 light sources.
Above content is the further explain that combines concrete preferred implementation that the utility model is done, and can not assert that the practical implementation of the utility model is confined to these explanations.Those of ordinary skill for technical field under the utility model; Under the prerequisite that does not break away from the utility model design, make some alternative or obvious modification that are equal to; And performance or purposes are identical, all should be regarded as belonging to the scope of patent protection that the utility model is confirmed by claims of being submitted to.
