Description

(5) ФОТОЭЛЕКТРИЧЕСКОЕ УСТРОЙСТВО ДЛЯ ОПРЕДЕЛЕНИЯ ПОЛОЖЕНИЯ ГРАНИЦЫ ОБЪЕКТА(5) PHOTOELECTRIC DEVICE FOR DETERMINING THE POSITION OF THE OBJECT LIMIT

1one

I .Изобретение относитс  к фотоэлектрическим измерени м в машиностроении и предназначено дл  автоматической регистрации заданного положени  ли- НИИ раздела поверхностей или зон с различной освещенностью, -например, штриховых отметок шкал, кромок режу ,щего инструмента и т.п.I. The invention relates to photoelectric measurements in mechanical engineering and is intended to automatically register a predetermined position of the line section of surfaces or areas with different illumination, for example, dashed scale marks, cutting edges, cutting tools, etc.

Известно фотоэлектрическое устройство дл  определени  положени  грани или кра  объекта, образуемого линией раздела поверхностей, содержащее отклон ющую пластину, разделительную призму и два фотоэлемента дл  регистрации световых потоков tl. Недостатком известного устройства  вл етс  то,что обнаружение штриховой отметки и регистраци  ее положени  осуществл ютс  раздельно за счет использовани  различных элементов устройства, причем, дл  обнаружени  штриха требуетс  механическое переме щение отклон ющей пластины,A photoelectric device is known for determining the position of a face or edge of an object formed by a surface dividing line, comprising a deflecting plate, a separating prism, and two photocells for detecting light fluxes tl. A disadvantage of the known device is that the detection of the bar mark and the registration of its position are carried out separately by using various elements of the device, and, to detect the bar, mechanical deflection of the deflection plate is required,

Наиболее .близким по технической сущности к изобретению  вл етс  фотоэлектрическое устройство дл  определени  положени  границы объекта, содержащее оптическую систему с м  фотоприемниками, например фотодиодами , три нуль-органа, элемент ИЛИ и делитель напр жени , образующие электронный блок . 1.The closest in technical essence to the invention is a photoelectric device for determining the position of an object boundary containing an optical system with m photodetectors, such as photodiodes, three zero-bodies, an OR element, and a voltage divider, forming an electronic unit. one.

К недостаткам устройства следует The disadvantages of the device should

10 отнести необходимость ручного переключени  электронного блока дл  изменени  режима работы, а вход щее в состав электронного блока дифференцирующее звено, примен емое 10 to attribute the need for manual switching of the electronic unit to change the mode of operation, and the differentiating element included in the electronic unit used

ts дл  ослаблени  вли ни  вариаций абсолютных значений, регистрируемых фотоприемником световых потоков, ухудшает отношение сигнал-шум в измерительном канале, что снижает точность ts for weakening the effect of variations in the absolute values recorded by the photoreceiver of the light fluxes degrades the signal-to-noise ratio in the measuring channel, which reduces the accuracy
