摘要： A miniaturized vacuum generator is powered by pressurized air, such as is commonly available in shop air lines. The generator includes a transducer coupled to the pressurized air line and utilizing the venturi principle to develope a vacuum at a vacuum port to which a vacuum hose may be coupled. This may be used in cleaning circuit boards and small electronic assemblies to pick off bits of solder, filings and other debris and contaiminants which more conventional vacuum cleaners do not effectively remove. The apparatus includes an in-line filter for collecting such debris and contaiminants and preventing them from being blown about by the exhaust. The apparatus may also be used as a pickup device for microchips and other miniature complements on an electronic assembly at a production line. Other uses of the device may be in the jewelry repair field where the debris to be picked up often contains dust and filings of precious metal and, occasionally, lost gemstones. The inline filter admits of ready disassembly for recovery of such materials. The device works without moving parts and is fabricated to a considerable extent from static dissipative materials to prevent the buildup of electrostatic charge which might damage charge-sensitive microchips and other components being handled or worked upon.
摘要翻译：小型真空发生器由加压空气供电，例如商店空气管线中通常可用的。发电机包括耦合到加压空气管线的换能器并利用文丘里管原理来在真空管可以耦合的真空端口处开发真空。这可以用于清洁电路板和小型电子组件，以拾取比较常规的真空吸尘器不能有效去除的焊料，填料和其他碎屑和污染物。该装置包括用于收集这些碎屑和污染物并且防止它们被排气吹过的在线过滤器。该设备还可以用作在生产线上的电子组件上的微芯片和其他微型补充物的拾取装置。该设备的其他用途可能在首饰修理领域，其中拾取的碎片通常含有贵重金属的灰尘和文件，并且偶尔会丢失宝石。在线过滤器允许准备拆卸以回收这些材料。该设备在没有移动部件的情况下工作，并且在很大程度上由静电消散材料制造，以防止静电电荷的积累，这可能会损坏对敏感的微芯片和其他被处理或加工的部件。
