Изобретение касаетс  способов визуального контрол  правильности расположенИЯ отверстий в детал х, например в печатных платах , и может найти лрименение в .производстве электрорадиоаопаратуры, а также в других отрасл х техники.The invention relates to methods for visually controlling the location of holes in parts, for example, in printed circuit boards, and can find application in the manufacture of radio electronic equipment, as well as in other areas of technology.

Известен способ визуального .контрол  .правильности расположеНИ  отверстий в детал х, например в печатных платах, заключающийс  в том, что эталоииую и контролируемую платы совмещают, между ними по:мещают слой светомассы, одновремеиио воздействуют на него ультрафн.олетовым излучением сквозь отверсти  одной из плат н просвечивают его монохроматическим светом сквозь отверсти  другой платы и определ ют правильность расположени  отверстий по цвету свечеин  их.There is a known method of visual control of the location of the holes in the parts, for example in printed circuit boards, which means that the reference and controllable boards are combined, between them: the layer of the light beam is influenced by UV light through the holes of one of the boards at the same time they shine with a monochromatic light through the holes of the other board and determine the correct position of the holes according to the color of the candles.

Однако при реализации этого способа необходимо применение источников ультрафиолетового и монохроматического света, а также светомассы. Источники ультрафиолетового и монохроматического света дорогосто щи и сложны, а светомасса иромыщленностью не вы.пускаетс .However, when implementing this method, it is necessary to use sources of ultraviolet and monochromatic light, as well as phosphor. Sources of ultraviolet and monochromatic light are expensive and complex, and the luminosity and intensity are not released.

Целью предлагаемого способа  вл етс  упрощение и удещевленне контрол .The aim of the proposed method is to simplify and reduce control.

Дл  этого поочере.дно пропускают через отверсти  деталей (Пульсирующий свет с частотон пульсации iiiiiKe или, будучи удвоеи)юй, BbiHie порога видимости пульсации света и Oinредел ют иравильность расположени  отверстий |Ио отсутствию иульсации света в Них.For this purpose, one passes through the holes of the parts (pulsating light with a ripple frequency iiiiiKe or, being doubled), BbiHie, the light pulsation visibility threshold and O determine the equilibrium position of the holes | Io without the pulsation of light in Them.

На чертеже изображена ириницилиальна  схема устройства дл  осуи:,ествлеап1  предлагаемого способа.The drawing shows an irinicial scheme of the device for the axle: most of the proposed method.

The direction of the display is shown by the arrow drawing.

Эталонную 7 и контролируемую 8 детали оитичеоки совмещают посредством иолупроз:рачиого зеркала, затем просвечивают их попеременио пульсирующпми источниками света 2 и 3, иолучающ1гми пптаиие от генератора неременного напр жени  4 через диоды 5 и 6.

The frequency of the geyrator is chosen so that it is received from the generator 4 through diodes 5 and 6. The frequency of the geyrator is chosen so that it is received from the generator 4 and diodes 5 and 6. The frequency of the geyrator is chosen so that it is received from the generator 4 and the diodes 5 and 6. The frequency of the geyrator is chosen so that it is received from the generator 4 and through diodes 5 and 6. The frequency of the geyrator is chosen so that it is received from the generator 4 and the diodes 5 and 6. , being, doubled} the 1st, viiie threshold of visibility of the pulsus eye (melkaiy) of light sources.
