Abstract
The invention discloses an application method of ultraviolet light in a circuit board overhauling station. An operator places a to-be-checked object on a platen of a microscopic system of the overhauling station and adjusts the brightness of white light and ultraviolet light to be in optimum states respectively according to the definition of images, videoscan clearly display images of a copper surface and a base material simultaneously, and a circuit board can be checked. If the circuit board is likely to be overhauled later, the operator can click for storage. Current optimum values of the white light and the ultraviolet light as well as data of the circuit board can be stored simultaneously. All that is required for checking of the same type of circuit boards is to call the data of the circuit board, the white light and the ultraviolet light are kept in the optimum states automatically and simultaneously, and any adjustment is not required.
Description
Technical field
The present invention relates to a kind of transformation and method for designing of optical device, it is specifically related to the application process of a kind of ultraviolet light in wiring board maintenance station.
Background technology
At present, the light-source system of present maintenance station all only has white light, the copper face of wiring board to white light reflection compared with strong and the light absorption of base material dialogue is not strong compared with multiple reflection, reason is that copper face is that metal and base material are that the material behavior of glass fibre determines, when if the brightness of white light is strong not, the copper face image of video image can be more clear and base material image can be darker, defect on base material is just not easy to differentiate like this, will increase so the undetected probability also attenuating greatly of overhaul efficiency simultaneously of defect on base material; Otherwise, when if the brightness of white light is enough strong, the base material image of video image can be more clear and copper face image will luminance saturation, defect on copper face is just not easy to differentiate like this, can increase equally the undetected probability also attenuating greatly of overhaul efficiency simultaneously of defect on copper face, so be badly in need of now addressing the above problem.
Accompanying drawing explanation
Fig. 1 is the white light of the application process of a kind of ultraviolet light of the present invention in wiring board maintenance station and the arrangement architecture schematic diagram of digital LED ultraviolet lamp.
Summary of the invention
In order to address the above problem, the object of this invention is to provide the application process of a kind of ultraviolet light in wiring board maintenance station, in solution wiring board maintenance station, copper face and glass fibre require to differ to make the darker or saturated undetected problem of wiring board defect that causes of detected image to light intensity.
For achieving the above object, the present invention takes following scheme:
Its concrete operations of application process in wiring board maintenance station of a kind of ultraviolet light of the present invention are as follows:
1) first at camera periphery, one circular lamp inner ring white light and a circular lamp outer ring purple light are tiltedly set, and coordinate the surrounding of circular lamp inner ring white light and circular lamp outer ring purple light to be provided with a plurality of low side lamps and a plurality of high side lamp.
2) open separately white light, the white light of wiring board copper face reflection enters camera lens by focusing lens, then imaging in video, wiring board copper face image effect in video is by adjusting white light intensity to best, the base material image effect of wiring board is general, be applicable to the requirement of copper face image inspection high, and the wiring board inspection not high to base material requires; Or
Open separately ultraviolet light, the fluorescence of base material reflection enters camera lens by focusing lens, then imaging in video, base material image effect in video is by adjusting purple light intensity to best, the copper face image effect of wiring board is general, be applicable to the requirement of base material image inspection high, and to the less demanding wiring board inspection requirements of copper face; Or
White light and ultraviolet light are opened simultaneously, the fluorescence of the white light of wiring board copper face reflection and base material reflection enters the camera imaging that can simultaneously receive white light and ultraviolet light by focusing lens simultaneously, the image that finally obtains copper face and base material optimum efficiency on video be applicable to most of to copper face and base material requires all high wiring board detect.
Described white light and/or ultraviolet light detect the light intensity optimum value of a wiring board and can be recorded by wiring board maintenance station, detect identical circuit board next time and continue to use.
Described a plurality of low side lamp and a plurality of high side lamp are white light.
The present invention is owing to taking above technical scheme, and it has following beneficial effect:
The application process of a kind of ultraviolet light of the present invention in wiring board maintenance station increases digital LED ultraviolet source on white light source basis, characteristic and the white light of ultraviolet light are contrary, ultraviolet lighting substantially all can be absorbed by copper face when copper face, so can not exert an influence to the image of copper face while increasing ultraviolet light, and ultraviolet lighting is on base material time, because substrate material is glass fibre, so can produce fluorescence, like this base material obtain brightness of image also can be very high, white light and ultraviolet light are arranged in pairs or groups while using simultaneously, all brightness is enough and unsaturated simultaneously can to make copper face and base material, so can obtain copper face and base material image clearly simultaneously.
