A particles capturing system includes a venturi filter device, a cyclone filter device, a plurality of first nozzles and air to flow through the system. The venturi filter device has an air intake portion, a neck portion and an air outlet portion. The cyclone filter device, disposed in the air outlet portion, has an entrance and an exit. The plurality of first nozzles, disposed inside the venturi filter device, have a height greater than that of the the neck portion. When the air flows, the air enters the venturi filter device via an air inlet of the air intake portion, then orderly passes through the neck portion and the plurality of first nozzles, then enters the cyclone filter device via the entrance, and finally leaves the cyclone filter device via the exit, such that particles in the flowing air can be captured.

A robotic vacuum cleaner is disclosed in the present invention, which comprises a controller, at least a driving wheel module, and a dust-collecting module. The controller is disposed on a housing plate. The driving wheel module, electrically connecting to the controller, further includes: a driver; a wheel connecting to the output shaft of the driver; a linkage rod, having two ends pivotally fixed on the housing plate and the driver respectively; and a resilience element, having two ends pivotally connected to the housing plate and the driver respectively. The dust-collecting module, disposed on the housing plate, is capable of vacuuming for filtering and collecting dust.

A cleaning device with sweeping and vacuuming functions includes a body accommodating a sweep module and a vacuum module. A main brush and an auxiliary brush driven by a power unit are pivoted in the sweep module. The main brush partially extends outside an opening at a bottom of the sweep module and contacts a ground surface. The sweep module has an outlet adjacent to a top of the auxiliary brush, and is pivoted in the body to freely and pivotally swing under weight. A first chamber of a dust collector of the vacuum module has an inlet corresponding to the outlet, and trash removed by the sweep module is collected into the first chamber. An air inlet communicating with an air intake component is formed above a second chamber of the dust collector. A suction port is formed below the second chamber to draw dust into the second chamber.

A brittle material breaking apparatus using a lifting mechanism to lift/lower a carrier wherein the lifting mechanism is controlled to lift the carrier for holding the brittle material for breaking, and then to lower the carrier from the brittle material to a distance for enabling the brittle material to be shifted to a next scribe line for further breaking, preventing the occurrence of friction between the brittle material and the carrier and the production of static electricity and micro particles and, improving the breaking quality. The brittle material breaking apparatus further includes a stroke fine adjustment mechanism adapted to adjust the stroke of the breaking-cutter relative to the brittle material.

Brittle material breaking apparatus

A cutting device for breaking fragile materials is constructed to include a lifting mechanism adapted to move the cutter vertically, a rotary table adapted to control the cutting angle of the cutter on the workpiece, a feed mechanism adapted to control the federate of the cutter, and a rotary mechanism adapted to rotate the cutter for enabling the cutter to cut the workpiece with one of multiple cutting points thereof selectively.

A precise and rapid positioning mechanism for stencil printing comprising a stencil, a carrier, a plurality of pins, and a plurality of positioning pins. There are a plurality of same sized pin eyes formed on both the stencil and the carrier respectively at positions facing against each other for interposing the pins therebetween to set the stencil and the carrier. Next, raising the positioning pins by air cylinder supplied from the carrier so as to fit setting holes on the substrate into the corresponding positioning pins thereby firmly securing the substrate. Then afterwards, by imbibing the substrate with vacuum evacuation force from the carrier so as to put down the positioning pins thereby attaching the stencil together with the substrate and trans-printing a desired pattern on the substrate.

A solder-ball supplying apparatus for a ball-grid array (BGA) IC packaging process is provided, which can supply solder balls of diameters from 0.5 mm to 1.0 mm at a preset amount to a solder-ball implanting machine. The solder-ball supplying apparatus is fully automated, in which vacuum means is used to suck out a preset amount of solder balls from a storage tank that are to be supplied. Rotary pneumatic cylinder means in conjunction with valve means are used to control the conveyance of the solder balls to the container. This solder-ball supplying apparatus can supply solder balls fast and in a non-contact manner that can prevent damage to the solder balls being supplied. It is fully automated so that manual labor is reduced and the quality of the solder balls being supplied can be assured.

Solder-ball supplying apparatus

An automatic ball placing device can automatically attach the solder ball to the pad of BGA's (Ball Grid Array) substrate. It comprises mainly a BGA substrate fixing device, a stencil fixing seat at least, a horizontal driving device, a vertical driving device and a swinging device. The BGA substrate possesses multiple stencil. The horizontal driving device and the vertical driving device can drive the said BGA substrate fixing device to perform horizontal and vertical movement respectively so as to move the BGA substrate to the position below the stencil fixing seat and thereby, make the solder balls drop into the mesh of the stencil which facilitates the solder balls to attach to the pad of BGA's substrate.
