Description
Technical field
The utility model relates to the checkout equipment of circuit board, says exactly the light supply apparatus of using for circuit board detecting.
Background technology
As everyone knows, all electric equipments or control system are all wanted the application of printed wiring board, and for guaranteeing wiring board stability and the life-span in use, printed-wiring board (PWB) 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-wiring board (PWB) outward appearance detects the main dual mode that adopts, and a kind of is to adopt visual inspection, and another kind is to adopt machine examination, namely adopts the automatic shape inspection machine to detect.
But these two kinds of modes all have the part defective: one, for visual inspection, its defective is larger 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, the appearance machine that uses on the market is to generally all no problem on processing, but it is coarse to wipe flower, little depression, protruding copper, golden face before the gold for part, on image acquisition, just there is very large problem, the image that collects is owing to angle, and the image that collects can not embody the image of defective strictly according to the facts, even this defective does not just show on image at all, thereby affect the analysis of software, produce the test leakage problem.And our this light source design is exactly to address this problem specially.
Summary of the invention
Find that after deliberation a key factor that affects the automatic shape inspection machine is light source, adopts rational light source, the erroneous judgement that can as far as possible avoid light to bring improves checking efficiency.
Based on this, technical problem to be solved in the utility model is to remedy above-mentioned automatic shape inspection machine the deficiencies in the prior art, proposes a kind of novel light supply apparatus, is applicable to printed-wiring board (PWB) to golden plate External Observation electricity testing device.
Another purpose of the present utility model is to provide a kind of detection gold plate light supply apparatus of automatic shape inspection machine, and this apparatus structure is simple, realizes easily, can improve checking efficiency, shortens the supervision time, reduces check cost.
In order to achieve the above object, the utility model is achieved through the following technical solutions.
A kind of detection gold plate light supply apparatus of automatic shape inspection machine, it is characterized in that this device includes: heat sink, aluminium base, LED lamp, astigmatism plate form; Wherein there are a plurality of LED lamps to be fixed on the inside surface of aluminium base, the outside surface of aluminium base is fixed with heat sink, the aluminium base below is provided with astigmatism plate, astigmatism plate is obliquely installed, the light that this device is sent shines from the side of wiring board, can guarantee accuracy and the reliability of institute's pickup image.The setting of aluminium base and heat sink is convenient to derive the amount of heat that the LED lamp produces; Astigmatism plate is put under the LED lamp, this light supply apparatus is arranged at wiring board one side, linear CCD (Charge-coupled Device, charge coupled cell, be also referred to as imageing sensor) absorb vertically downward the circuit board drawing picture by the inspection machine top from the light source next door, like this, by the irradiation of monolateral light source, depression and protruding copper point that golden face is tiny are reflective in CCD, to realize Accurate Analysis.
Described astigmatism plate is arranged at 25-35mm place under the LED lamp, make light source shine by astigmatism plate on the wiring board of below softer evenly.
Described LED lamp is high-powered LED lamp.
Described aluminium base has at least two kinks at an angle, and heat radiator is fixed on the outside surface of described kink, with can quick heat radiating; The LED lamp is installed in the inside surface of kink, by astigmatism plate wiring board is shone.
Described LED lamp, the LED lamp of each kink are cumulative from level to level circle or square arrangement, so that produce evenly soft light.
Described astigmatism plate and wiring board are 35-50 ° of angle, so that shine.Reasonable mode is to be slightly less than 45 °, can effectively avoid the refraction of light.
Described device also includes the reflector of mirror face stainless steel, and described reflector is arranged between astigmatism plate and the aluminium base, and an end is connected in the outer rim of astigmatism plate, and an end connects aluminium base.
The utility model beneficial effect compared with prior art is that the characteristics of this Novel light source are: light source adopts aluminium base that great power LED is connected heat radiation with heat sink, simultaneously, after filtering, the light source that LED uses the below astigmatism plate that LED is produced becomes evenly soft, and shine from the side of wiring board, can accurately absorb the image of wiring board, be convenient to the judgement of wiring board defective, improved inspection speed and checking efficiency.Adopt new light-source angle to compare with old light source, the image color of breaking forth and homogeneity are better truer, can accurately catch golden face tiny on the wiring board is concavo-convex, are very beneficial for follow-up computer software to crawl and the processing of this defect problem.
