Slip occurs when adsorbed.

Description

Open microporous airflow carrier

The present invention relates to an air flow carrier having an open microporous which is applied to a nozzle and provides a balanced adsorption force.

In an automated production facility, in order to enable a thin plate or the like to be moved quickly, the existing automated production equipment mostly uses a nozzle connected to the drive mechanism to perform an object removal operation by vacuum suction.

The nozzle structure currently known, as shown in FIG. 7 and FIG. 8 , has a nozzle body 40 of a soft material, and a cavity opening downward is formed in the nozzle body 40, and the top of the nozzle body 40 is used. The connecting duct 41 is connected, and the driving mechanism and the air suction system are connected through the duct 41.

The existing nozzles can be used with the pumping system to provide quick access to thin plates and other objects. However, as shown in FIG. 8, when the thin plate 50 is sucked by the suction nozzle body 40 directly by the vacuum suction means by the existing nozzle, the thin plate 50 is easily concentrated due to vacuum adsorption and the force is too large, and the thin plate 50 is The adsorption site of the nozzle produces a problem of adsorption traces.

In order to improve the suction nozzle body of the conventional nozzle described above, when the thin flat plate is directly sucked, the portion where the thin flat plate is sucked by the suction nozzle may cause a problem of adsorption marks. Further, a porous foam gasket (not shown) is further disposed on the nozzle body, so as to reduce the adsorption pressure through the majority of the pores of the foam gasket, thereby reducing the problem of adsorption traces on the thin plate being adsorbed by the nozzle. . However, most of the pores in the foam gasket are non-open porous structures, and only a part of the pores are connected to each other. Therefore, the suction nozzle is thin in suction suction. The process of the type of flat plate and the like is easily blocked by the foam gasket due to the pumping action, and the vacuum pressure is obviously decreased, which affects the overall adsorption capacity of the suction nozzle to suck the thin flat plate and the like.

In addition, a person also has a porous member having an open hole in the nozzle body, and the bottom surface of the porous member and the other outer surface are smooth surfaces, whereby the suction nozzle adsorbing the object with the porous member is adsorbed. No dents or signs of adsorption can be produced on the surface of the object.

However, the above-mentioned porous element having an open pore is applied to the object of the nozzle to adsorb the object, and the function of the object to be adsorbed does not cause dents or adsorption marks when the object is adsorbed, however, the contact is in the outer surface of the porous member. The bottom surface of the object is a smooth plane. When the porous element contacts the top surface of the object, the frictional resistance between the smooth bottom surface of the porous element and the object is insufficient, and the relative slip phenomenon is likely to occur during the suction of the suction cup, which is not suitable for the adsorption movement. The precise alignment of the object to the destination is necessary for further improvement.

The purpose of the present invention is to provide an air carrier with an open microporous shape, which can solve the problem that the existing nozzle absorbs the thin plate and easily generates adsorption traces. When the foam gasket is added inside the nozzle, the non-open pore structure in the foam gasket is caused. However, when the vacuum pressure is lowered when the thin plate is adsorbed, and the porous member is added inside the nozzle, the bottom surface of the element contacting the object to be adsorbed is a smooth plane, and slippage occurs during the adsorption process.

In order to achieve the foregoing, the present invention provides an open microporous air flow carrier system including A plurality of pyramids or cylinders in which a plurality of plastic micro-particles are cross-linked to each other, and a bottom surface of the air carrier forms a rough surface. The gas carrier forms an open microporous structure between a plurality of the microparticles cross-linked with each other, and the open microporous structure comprises a plurality of dispersed and interconnected fine pores to form a stereo network. And extending from a top surface of the air carrier to a bottom surface of the air carrier and a peripheral surface of the air carrier.

In order to achieve the foregoing object, another open microporous gas flow carrier provided by the present invention comprises a plurality of micro-particles of general-purpose plastic material which are cross-linked and formed, and the gas flow carrier comprises a carrier upper portion and the carrier. a lower portion of the carrier below the upper portion, the upper portion of the carrier is formed by a cone having a decreasing size from top to bottom, and the lower portion of the carrier is formed by a cone having an increasing size from top to bottom, and an outer peripheral surface of the middle portion of the air carrier is formed. a concave ring-shaped recess, the bottom surface of the air flow carrier forming a rough surface; the air flow carrier forms an open microporous structure between the plurality of micro-particles cross-linked, the open micro-porous structure comprising a majority dispersion And the microscopic channels communicating with each other form a three-dimensional network, and extend from the top surface of the air carrier to the bottom surface of the air carrier and the peripheral surface of the air carrier.

By preliminarily exposing an open microporous air flow carrier, it is installed in the nozzle body of the nozzle, and when the air suction system sucks the thin flat plate through the suction nozzle, the air flow carrier provided in the nozzle body borrows The open microporous structure makes the vacuum pressure through the nozzle not significantly decrease, and on the basis of maintaining its proper vacuum adsorption capacity, further through the gas carrier, the majority of the dispersed fine pores communicate with each other to form a three-dimensional network. The open microporous structure disperses the adsorption force of the suction nozzle on the thin flat plate to the entire bottom surface of the air flow carrier, balances the adsorption force, and avoids the phenomenon that the adsorption force is excessively concentrated, so that the thin plate is not adsorbed by the suction nozzle. .

Secondly, it is disclosed that a plurality of microparticles of the gas carrier are crosslinked to form an open microporous structure comprising a plurality of fine pores, and the bottom surface of the gas carrier is crosslinked by a plurality of microparticles to form a non-smooth rough surface. Therefore, when the nozzle having the air flow carrier is in the process of adsorbing the thin flat plate, the bottom surface of the thin flat plate is contacted by the air flow carrier as a rough surface, and has appropriate The frictional resistance prevents the slippery phenomenon from being absorbed by the suction nozzle of the airflow carrier, and ensures that the object to be moved and moved can be accurately aligned when it is moved to the destination by the suction nozzle.
