Gas-liquid separation device for vacuum chuck

Abstract

The utility model provides a gas-liquid separation device for a vacuum chuck, which comprises a gas inlet pipe, a vacuum generator, a connecting pipe, a closed separation barrel and a negative pressure pipe, the gas inlet pipe is connected with a positive pressure port of the vacuum generator, one end of the connecting pipe is connected with a negative pressure port of the vacuum generator, and the other end of the connecting pipe is connected with the closed separation barrel. When high-speed jet compressed air enters the vacuum generator from the air inlet pipe, negative pressure is formed in a negative pressure opening of the vacuum generator, so that air in the negative pressure pipe enters the closed separation barrel and enters the vacuum generator from the connecting pipe, and the air in the closed separation barrel is separated from the vacuum generator. When negative-pressure gas enters the closed separation barrel, due to the fact that the density of the gas is smaller than that of liquid, the liquid naturally drips and is accumulated at the bottom of the closed separation barrel, the separated negative-pressure gas enters the vacuum generator through the connecting pipe, and the phenomenon that the negative-pressure gas with water enters the vacuum generator is avoided; and the vacuum generator cannot be damaged.

Description

Technical Field

[0001] The utility model relates to the technical field of gas-liquid separation devices, in particular to a gas-liquid separation device for a vacuum suction cup. Background Art

[0002] During the production process of silicon parts, the silicon parts need to be fixed on the workbench of the machine tool. However, the use of fixtures can easily damage the surface of the silicon parts. Therefore, during the production process, vacuum suction cups are usually used to adsorb the silicon parts so that they are fixed on the machine tool for processing and production.

[0003] The working principle of the vacuum suction cup is mainly based on the principle of air pressure difference in physics. The working principle of the vacuum generator is to use a nozzle to spray compressed air at high speed, forming a jet at the nozzle outlet to generate entrainment flow. Under the action of entrainment, the air around the nozzle outlet is continuously sucked away, causing the pressure in the adsorption chamber to drop below atmospheric pressure, forming a vacuum environment.

[0004] In order to reduce the heat generated by cutting or grinding the workpiece, the common vacuum suction cup will spray coolant on the surface of the workpiece during processing. This will easily cause the coolant to adhere to the vacuum suction cup. When the high-speed compressed air is sprayed to form a negative pressure at the nozzle outlet, the moisture in the negative pressure gas cannot be separated, causing the negative pressure air to carry the moisture into the vacuum generator, causing damage to the vacuum generator. Utility Model Content

[0005] The utility model aims to provide a gas-liquid separation device for a vacuum suction cup in view of the defects and shortcomings of the prior art.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a gas-liquid separation device for a vacuum suction cup, comprising an air inlet pipe, a vacuum generator, a connecting pipe, a closed separation barrel, and a negative pressure pipe, wherein the air inlet pipe is connected to the positive pressure port of the vacuum generator, one end of the connecting pipe is connected to the negative pressure port of the vacuum generator, the other end of the connecting pipe is connected to the upper end of the closed separation barrel, one end of the negative pressure pipe is connected to the side end of the closed separation barrel, and the other end of the negative pressure pipe is connected to an external vacuum suction cup.

[0007] A further improvement is that the enclosed separation barrel is arranged longitudinally.

[0008] A further improvement is that a stabilizing plate is provided at the lower end of the closed separation barrel for improving the placement stability of the closed separation barrel when the closed separation barrel is placed on the ground.

[0009] A further improvement is that a universal sliding wheel set is arranged at the lower end of the stabilizing plate.

[0010] A further improvement is that: the air inlet pipe is also provided with a solenoid valve, and the solenoid valve is arranged on the upper end surface of the closed separation barrel.

[0011] A further improvement is that a liquid drain piece is provided at the lower end of the sealed separation barrel.

[0012] A further improvement is that the drainage member includes a drainage hole opened at the lower end of the closed separation barrel, and an automatic drainage valve arranged on the lower end surface of the closed separation barrel and located in the drainage hole.

[0013] After adopting the above technical scheme, the beneficial effect of the utility model is as follows: when high-speed jet compressed air enters the vacuum generator from the air inlet pipe, the negative pressure port of the vacuum generator forms a negative pressure, so that the gas in the negative pressure pipe enters the closed separation barrel and enters the vacuum generator from the connecting pipe. When the negative pressure gas enters the closed separation barrel, since the density of the gas is less than that of the liquid, the liquid naturally drips and accumulates at the bottom of the closed separation barrel, and the separated negative pressure gas enters the vacuum generator through the connecting pipe, which will not cause the negative pressure air to enter the vacuum generator with moisture, and will not cause damage to the vacuum generator.

[0021] See also Figures 1 to 4As shown, the technical solution adopted in this specific embodiment is: a gas-liquid separation device for a vacuum suction cup, comprising an air inlet pipe 1, a vacuum generator 2, a connecting pipe 3, a closed separation barrel 4, and a negative pressure pipe 5, wherein the air inlet pipe 1 is connected to the positive pressure port of the vacuum generator 2, one end of the connecting pipe 3 is connected to the negative pressure port of the vacuum generator 2, the other end of the connecting pipe 3 is connected to the upper end of the closed separation barrel 4, one end of the negative pressure pipe 5 is connected to the upper end of the closed separation barrel 4, and the other end of the negative pressure pipe 5 is connected to an external vacuum suction cup.

[0022] The sealed separation barrel 4 is arranged longitudinally. The sealed separation barrel 4 can also be arranged transversely. When the sealed separation barrel 4 is arranged transversely, the connecting pipe 3 and the negative pressure pipe 5 are both arranged on the upper end surface of the sealed separation barrel.

[0023] A stabilizing plate 6 is provided at the lower end of the closed separation barrel 4 for improving the placement stability of the closed separation barrel 4 when the closed separation barrel 4 is placed on the ground.
