Возвратно-поступательное дви- j жение каретки 34 обеспечивается ры- чагом 42, кинематически связанным с приводом 2 тягой 43 и кулачком 44, а вращение - приводом 45 через однооборотную муфту 46. Измерительные головки 9 снабжены неподвижными 47 и подвижными 48 контактами, расположенными по обе стороны подвижной диэлектрической перегородки 49, которая связана с подпружиненными рычагами 50, находящимися на оси 51. Рычаги 50 обеспечивают поджатие выводов радиодеталей 10 подвижными 48 , и неподвижными 47 контактами. Контакты 47 электрически связаны с ламелями 52, с которыми контактируют щетки 12 и 13, ис ламелями 53 и 54, с которыми контактируют щетки 30. Перемещение измерительных головок 9 параллельно оси вращения ротора вдоль его образующей для подключения радиодеталей к измерительным приборам осуществляется приводом 55 через муфту 56 в момент выстоя ротора. Ротор и механизмы выгрузки и загрузки размещены на основании 57.The cassette 31, from which the radio components 10 are transferred to the measuring head, 9, is located so that their conclusions, mounted on the cassette, are located under the knife 33, and the cases of the radio components are in the longitudinal grooves of the carriage 34 of the loading mechanism,. moreover, the conclusions of the radio components are fixed by slots in the L-shaped covers 36 pivotally mounted on the axes 35.

The rotor and unloading and loading mechanisms are located on the base 57.

Устройство для контроля электрических параметров радиодеталей работает следующим образом.A device for monitoring the electrical parameters of radio components works as follows.

Ротор 1 вращается прерывисто в направлении стрелки от привода 2 с помощью зубчатых колес 3-6 с определенным циклом. С этим же циклом из магазина 32 на позицию перекладки подаются кассеты 31. Рычагом 42 каретка 34, находящаяся на ползуне 37, 5 подводится в направлении кассеты 31 с поднятой крышкой 36 с тем, чтобы корпусы радиодеталей 10 зашли в лотки. После этого крышка 36 закрывается. Прорези в крышке жестко фиксиру- ю ют выводы радиодеталей 10, а нож 33 отделяет радиодетали от кассеты 31. Подается команда на включение однооборотной муфты 46 и с помощью привода 45 каретка 34 поворачивается 15 в направлении стрелки на 180 . Ползун 37 под действием пружин 39 отводится в направлении ротора 1. К этому моменту подвижные контакты 48 измерительных головок 9 и диэлектричес-20 кие перегородки 49 отделены от неподвижных контактов 47 рычагами 50. Выводы радиодеталей 10 заводятся между контактами 47 и 48 по обе стороны диэлектрической перегородки 49, 25 после чего контакты 48 поджимают выводы радиодеталей к неподвижным контактам 47, крышка 36 поднимается и каретка 34 отводится для загрузки нового ряда радиодеталей, а ротор 1 поворачивается на один шаг. По мере вращения ротора 1 в определенной технологической последовательности в течение определенного времени (на нескольких позициях одновременно) на радиодетали, находящиеся в измери-^⁵тельных головках 9, с помощью щеток 12 и 13 подается электрическое напряжение, а затем на следующей позиции радиодетали подключаются к измерительному прибору. При использовании ⁴⁰одноканального измерительного прибора без электронного коммутатора подключение к этому прибору осуществляется в момент выстоя ротора путем перемещения измерительной головки 9 параллельно оси вращения ротора вдоль его образующей от привода 55 через муфту 56. Результаты контроля фиксируются в запоминающем устройстве, которое на позициях выгрузки при сортировке радиодеталей на группы ’’Годные и Брак включает необходимые механизмы загрузки, состоящие из электромагнитов 15 и толкателей 16. ⁵⁵ The rotor 1 rotates intermittently in the direction of the arrow from the drive 2 with the help of gears 3-6 with a certain cycle. With the same cycle, cassettes 31 are fed from the magazine 32 to the transfer position. With the lever 42, the carriage 34 located on the slider 37, 5 is fed in the direction of the cartridge 31 with the cover 36 raised so that the cases of the radio components 10 go into the trays. After that, the cover 36 closes. The slots in the cover firmly fix the terminals of the radio components 10, and the knife 33 separates the radio components from the cartridge 31. A command is given to turn on the single-turn clutch 46 and, using the drive 45, the carriage 34 rotates 15 in the direction of the arrow by 180. Under the action of the springs 39, the slider 37 is diverted in the direction of the rotor 1. At this point, the movable contacts 48 of the measuring heads 9 and the dielectric partitions 49 are separated from the fixed contacts 47 by levers 50. The terminals of the radio components 10 are inserted between contacts 47 and 48 on both sides of the dielectric partition 49, 25 after which the contacts 48 press the terminals of the radio components to the stationary contacts 47, the cover 36 rises and the carriage 34 is retracted to load a new series of radio components, and the rotor 1 rotates one step. As the rotor 1 in a particular processing sequence for a predetermined time (in several positions simultaneously) on radio located in the measuring heads-negative ^ ⁵ 9 via brushes 12 and 13 is applied an electric voltage, then at the next position they are connected to the radio measuring device. When using a ⁴⁰ single-channel measuring device without an electronic switch, the connection to this device is carried out at the moment of rotor standby by moving the measuring head 9 parallel to the axis of rotation of the rotor along its generatrix from the actuator 55 through the coupling 56. The monitoring results are recorded in the storage device, which is at the unloading positions when sorting radio parts into the groups '' Good and Marriage includes the necessary loading mechanisms, consisting of electromagnets 15 and pushers 16. ⁵⁵

С целью сокращения числа этих механизмов, а значит и упрощения кон струкции, сброс радиодеталей из измерительной головки осуществляется в момент выстоя ротора в каждом цикле за несколько шаговых поперечных перемещений измерительных головок 9 от приводов 55.In order to reduce the number of these mechanisms, and thus simplify the design, the radio components are reset from the measuring head at the moment the rotor is in each cycle for several stepwise transverse transverse movements of the measuring heads 9 from the drives 55.

Перед каждым поперечным перемещением измерительных головок 9, находящихся на позициях выгрузки, кулачком 18 через тягу 17 отводится кронштейн 14 так, чтобы установленные на нем толкатели 16 выходили изпод рычагов 50 измерительных головок. Затем по команде запоминающего устройства включаются соответствующие электромагниты 15 и опущенными под их действием толкателями 16 при обратном качании кронштейна отводится новая группа рычагов 50 измерительных головок 9. Контакты 47 и 48 раскрываются с одновременным отводом диэлектрической перегородки 49. Отвод последней устраняет зависание на ней сбрасываемых радиодеталей 10, которые под действием силы тяжести падают в расположенный под ротором бункер 20.Before each transverse movement of the measuring heads 9 located at the unloading positions, the cam 14 retracts the bracket 14 through the rod 17 so that the pushers 16 mounted on it exit from the levers 50 of the measuring heads. Then, at the command of the storage device, the corresponding electromagnets 15 are turned on and the pushers 16 lowered under their action when the arm is swinging back, a new group of levers 50 of the measuring heads 9 is withdrawn. Contacts 47 and 48 are opened with the simultaneous removal of the dielectric partition 49. The removal of the latter eliminates the hang of the reset radio components 10 on it which, under the action of gravity, fall into the hopper 20 located under the rotor.

На последней позиции выгрузки к радиодеталям, расположенным в измерительной головке 9, подводится в момент выстоя ротора лоток 21 так, чтобы корпусы радиодеталей 10 разместились в лотке, затем заслонка 27, управляемая электромагнитом 28, запирает радиодетали в лотке 21. Лоток 21, находясь на шарнирном рыча)ге, поворачивается и занимает положение, соосное с накопителем 29, после чего заслонка открывается и радиодетали поступают в накопитель 29. Такое принудительное удаление радиодеталей повышает надежность работы устройства и позволяет вщцавать необходимый номинал радиодеталей в ориентированном виде для дальнейших технологических операций (например, маркировка или упаковка).At the last unloading position, a tray 21 is brought to the radio components located in the measuring head 9 at the moment the rotor is stationary, so that the cases of the radio components 10 are placed in the tray, then the shutter 27, controlled by the electromagnet 28, locks the radio components in the tray 21. The tray 21, being on the hinge growling), it turns and occupies a position coaxial with drive 29, after which the damper opens and the radio components enter drive 29. Such forced removal of radio components increases the reliability of the device and allows it to the required nominal of radio components in an oriented form for further technological operations (for example, marking or packaging).
