Description

Изобретение относится к технологическому оборудованию для производства изделий микроэлектроники и предназначено для использования на различном технологическом оборудовании, связанном с загрузочно-разгрузочными операциями и транспортированием изделий, преимущественно микросхем в плоских корпусах с планарными выводами.The invention relates to technological equipment for the production of microelectronics products and is intended for use on various technological equipment associated with loading and unloading operations and transportation of products, mainly microcircuits in flat cases with planar leads.

Известна кассета для микросхем, содержащая основания, снабженные жестко соединяющим их перекрытием, с поперечными пазами для размещения изделий. Для предотвращения выпадения изделий при перевертывании кассеты, она снабжена съемной крышкой-фиксатором в виде гибкой пластида, устанавливаемой концами в окна перекрытия. Перед загрузкой изделий в кассету необходимо раскрыть ее, т.е. высвободить любой конец крынки-фиксатора и вытащить ее из кассеты. После этого производят загрузку изделий и устанавливают крышку-фиксатрр обратно[1].Known cassette for microcircuits, containing the base, equipped with a rigidly connecting their overlap, with transverse grooves for placement of products. To prevent the product from falling out when the cassette is turned over, it is equipped with a removable lid-lock in the form of a flexible plastid, which is installed by the ends in the overlap windows. Before loading products into the cartridge, it is necessary to open it, i.e. Release either end of the locking tab and pull it out of the cassette. After that, the product is loaded and the lid-fixator is installed back [1].

Недостатком этой кассеты является неудобство при ее использовании, обусловленное наличием съемной крышки-фиксатора, которую надо снимать, а затем вставлять. Кроме того, чтобы крышки-фиксаторы не терялись, требу2 ется специальное место для их хранения. Другим недостатком этой кассеты является ограниченность ее функцио, нальдах возможностей, обусловленная тем, что загрузку и выгрузку изделий можно производить лишь с одной стороны, и тем, что невозможно перегрузить изделия из одной кассеты в другую без потерн первоначальной ориентации перегружаемыми изделиями.The disadvantage of this cartridge is the inconvenience of its use, due to the presence of a removable lid-retainer, which must be removed and then inserted. In addition, so that the retainer caps are not lost, a special place for their storage is required. Another drawback of this cartridge is its limited functionality and potential, due to the fact that loading and unloading of products can only be done on one side, and because it is impossible to reload products from one cartridge to another without losing the initial orientation of the loaded products.

Цель изобретения - расширение функциональных возможностей и повышение удобства использования.The purpose of the invention is the expansion of functionality and increase usability.

Указанная цель достигается тем, что в кассете для микросхем, содержащей два связанных между собой соединительными элементами П-образных основания, обращенных одно к другому своими средними стенками, в ко20 торых выполнены поперечные_;пазы для размещения микросхем, и снабженной ’ фиксаторами микросхем, соединительные элементы выполнены в виде плоских пружин замкнутой формы, закреп25 ленных на средних стенках П-образных оснований с образованием упругого шарнира, а фиксаторы выполнены в виде выступов, расположенных вдоль краев средней части П-образных осно30 ваний между их поперечными пазами.This goal is achieved by the fact that in the cassette for microcircuits containing two interconnected connecting elements of the U-shaped base, facing one another with their middle walls, in which transverse are made _; grooves for accommodating microcircuits, and equipped with microcircuit latches, the connecting elements are made in the form of flat springs of closed shape fixed on the middle walls of the U-shaped bases with the formation of an elastic hinge, and the latches are made in the form of protrusions located along the edges of the middle part of the U-shaped bases between their transverse grooves.

На фиг, 1 изображена кассета, общий вид) на фиг. 2 - кассета в закрытой состоянии с микросхемами; на фиг. 3 и 4 - кассета в раскрытом состоянии с одной и другой сторон.In FIG. 1, a cassette is shown, general view) in FIG. 2 - cassette in the closed state with microcircuits; in FIG. 3 and 4 - cassette in the opened state from one and the other side.

Кассета содержит два П-образных _ основания 1, обращенных друг к дру- ⁵гу средними стенками 2, с поперечными пазами 3 для размещения микросхем 4, фиксаторы 5, выполненные в виде продольных треугольных выступов на крадх средних стенок 2 оснований 1 10 и соединительные элементы оснований 1 в виде плоских пружин 6 замкнутой фор мл, образующих упругие шарниры.The cassette contains two U-shaped _ bases 1 facing each other with ⁵ middle walls 2, with transverse grooves 3 to accommodate chips 4, clips 5 made in the form of longitudinal triangular protrusions on the cradle of the middle walls 2 of bases 1 10 and connecting elements bases 1 in the form of flat springs 6 closed form ml forming elastic hinges.

Работа с кассетой происходит следующим образом. 15Work with the cartridge is as follows. fifteen

В исходном положении (фиг. 2) средние стенки 2 оснований 1 параллельны друг другу и фиксаторы 5 надежно удерживают микросхемы 4, размещенные в Паза 3., от выпадения из кассеты 20 в любом ее расположении в пространстве.In the initial position (Fig. 2), the middle walls 2 of the bases 1 are parallel to each other and the latches 5 reliably hold the microcircuits 4, located in the groove 3., from falling out of the cartridge 20 in any location in space.

Для разгрузки (или загрузки^изделий из кассеты необходимо развести основания 1 в противоположные стороны с любой из двух сторон кассеты. Это осуществляется-за счет наличия соединительных элементов в виде упругих шарниров, образованных пружинами 6.For unloading (or loading ^ products from the cartridge, it is necessary to spread the bases 1 in opposite directions from either of the two sides of the cartridge. This is due to the presence of connecting elements in the form of elastic joints formed by springs 6.

• При разведении оснований 1 расстоя-30 ние между фиксаторами 5 становится больше размера корпуса микросхемы 4 и они свободно проскальзывают между фиксаторами 5.• When breeding bases 1, the distance between the latches 5 becomes larger than the size of the housing of the microcircuit 4 and they freely slip between the latches 5.

Разведение оснований 1 с одной 35 из двух сторон выполняется вручную, или автоматически при установке кассеты в технологическое оборудование.Dilution of the bases 1 with one of 35 of the two sides is carried out manually, or automatically when installing the cartridge in the processing equipment.

Благодаря наличию упругих шарниров основания 1 разводятся только с нужной стороны кассеты (с которой производится загрузка или разгрузка), при этом другая сторона остается закрытой. При съеме кассеты с технологического оборудования основания 1 с обеих сторон кассеты занимают исходное положение, при котором кассета закрыта с двух сторон, фиксаторы 5 надежно удерживают микросхемы 4 в кассете и ни при каких пространственных перемещениях кассеты изделия не могут из нее выпасть.Due to the presence of elastic hinges, the bases 1 are bred only from the desired side of the cassette (from which loading or unloading is performed), while the other side remains closed. When removing the cartridge from the processing equipment, the bases 1 on both sides of the cartridge occupy the initial position, in which the cartridge is closed on both sides, the clips 5 securely hold the microcircuits 4 in the cartridge and under any spatial movements of the cartridge, the products cannot fall out of it.

To prevent items from falling out when the cassette is turned over. it is equipped with a removable fixative cover in the form of a flexible plastid installed by KOHuaNOi in the windows of the ceiling. Before loading products into the cassette, it is necessary to open it, i.e. Release any end of the lock-clip and pull it out of the cassette. After this, the products are loaded and the fixing cover is put back. The disadvantage of this cassette is the inconvenience of using it, due to the presence of a removable lid that needs to be removed and then inserted. In addition, in order to prevent the legal fixers from being lost, a special place is required for their storage. Another disadvantage of this cassette is its limited functionality due to the fact that loading and unloading of products can be done only on one side, and the fact that it is impossible to reload products from one cassette to another without losing the original orientation of the overloaded products. The purpose of the invention is to enhance the functionality and increase the usability. This goal is achieved by the fact that in a microcircuit cassette containing two interconnected connecting elements of U-shaped bases, facing one another by their middle walls, in which transverse J-slots are made to accommodate the microcircuits, and provided with fixers of microcircuits, the connecting elements are made flat springs of the closed form, fixed on the middle walls of the U-shaped bases with the formation of an elastic hinge, and (the xators are made in the form of protrusions located along the edges of the middle part of -shaped bases between their transverse grooves.
