Background

Companies that manufacture semiconductors, semiconductor devices, LCDs, and OLEDs, and all companies that use harmful chemicals, such as pharmaceutical companies and paint companies, use a variety of chemicals, and the way to safely supply such chemicals is also varied.

Such chemicals are generally delivered from a chemical tank of a tank truck (tank) stopped outside a building to a chemical storage tank (chemical storage tank) installed inside the building, and then delivered from the chemical storage tank to a unit project process chamber.

The conventional method of delivering chemicals from the above-described tank truck to the chemical storage tank uses a method in which an operator manually connects a hose and a joint for supplying chemicals, which will be described in detail below.

The tank car is connected with a chemical supply hose and a nitrogen supply hose, the end parts of the chemical supply hose and the nitrogen supply hose are respectively connected with a Male joint (Male Connector) for chemicals and a Male joint for nitrogen, and the Male joints are respectively provided with a closed end part of a cover (Cap).

The chemical tank is provided with a chemical Female Connector (Female Connector) and a nitrogen Female Connector, and a chemical male Connector and a nitrogen male Connector are inserted into the chemical Female Connector and the nitrogen Female Connector, respectively. The chemical female connector and the nitrogen female connector are also provided with caps (Cap) respectively for closing the ends.

The operator pulls out the chemical hose and the nitrogen hose from the tank car, and separates the chemical male joint cover and the nitrogen male joint cover from the chemical female joint cover and the nitrogen female joint cover. Thereafter, the chemical male connector is connected to the chemical female connector, and the nitrogen male connector is connected to the nitrogen female connector.

As described above, in a state where the male connector and the female connector are connected, nitrogen gas of a constant pressure is supplied from the nitrogen gas storage tank located in the building to the tank car through the nitrogen gas hose, and the chemical in the tank car is transferred to the chemical storage tank through the chemical hose due to the pressure of the nitrogen gas.

However, according to this conventional method, when an operator manually connects and separates the chemical and nitrogen gas joints and supplies nitrogen gas at a constant pressure, the chemical may leak out, and the operator may be exposed to the chemical.

As a prior art of the chemical supplying apparatus, Korean Utility model laid-open No. 20-2016-.

In the above prior art, a chemical intermediary means called ACQC Unit (Automatic Clean Quick Coupler Unit) is provided between the tank truck and the chemical storage tank. Here, the chemical storage tanks are typically located within the building, and the ACQC units mediate between the chemical tanks of the tanker trucks and the chemical storage tanks within the building.

According to the conventional ACQC unit, in a state where the chemical male and female connectors are connected and the nitrogen male and female connectors are connected, nitrogen gas of a constant pressure is supplied to the chemical tank of the tank car through the ACQC unit, and chemicals are discharged by using the pressure of the supplied nitrogen gas and stored in the chemical storage tank through the chemical hose.

At this time, the chemical hose and the nitrogen hose are required to be placed on the shelf. When the placing part supports the male joint combined with the end part of the chemical hose and the nitrogen hose, when the body is directly contacted, the body of the male joint can be damaged or polluted by the contacted placing part, and when the polluted male joint is combined with the female joint, the problem of chemical pollution or deterioration can be caused.

Further, in order to prevent the wrong input of different chemicals, a Key Code (Key Code) is required, and when the Key Code is directly provided on the male connector outer body, the male connector body is damaged, and a member for forming the Key Code is additionally provided.

The lower end of the handle portion 156 and the upper end of the handle case 156b may be formed with a concavity and a convexity formed by a valley and a peak along the circumference of the contact surface. When the peak of the handle portion 156 and the peak of the handle case 156b contact each other, the handle portion 156 and the handle case 156b are isolated from each other. When the above-mentioned peaks/valleys of the handle portion 156 meet the valleys/peaks of the handle case 156b, respectively, the handle portion 156 and the handle case 156b approach each other due to the pulling force of the elastic member. Thus, the operator may rotate the handle portion 156 to cause the peak to peak or peak to valley to meet.

When the fixing pin 154 is moved backward, as shown in fig. 13, the lower end of the sensing pin 156a contacts the upper surface of the supporting plate 157. At this time, the grip portion 156 and the fixing pin 154 are in a state of moving upward relative to the grip case 156b, and the elastic member is in a stretched state.

In the state of fig. 13, when the operator grips the handle portion 156 and pushes it forward, the fixing pin 154 moves forward integrally with the moving member 153 and the sensing pin 156a, and when the fixing pin 154 is inserted into the fixing pin insertion portion 535, the sensing pin 156a is positioned above the through hole 157 a.

In this state, when the operator rotates the handle portion 156, the valley and the peak of the handle portion 156 and the handle case 156b meet each other, the sensing pin 156a and the handle portion 156 are pulled downward by the elastic member, and as shown in fig. 14, the sensing pin 156a moves downward by the elastic member, passes through the through hole 157a, and is positioned above the lock sensor 158.

The locking sensor 158 senses the sensing pin 156a, whereby the operator can know that the chemical hose 500 and the nitrogen hose 600 are fixed to the shelf portion 150 for the next operation. If the lock sensor 158 does not sense the sensing pin 156a, the automatic chemical supplying apparatus 100 is not operated.

The operation of the chemical automatic apparatus 100 of the present invention having the above-described configuration will be described.

The operator rotates and opens the upper door 132 of the shield door 130 upward. At this time, the shelf 150 is located inside the frame 120, adjacent to the shield door 130.

A chemical male joint 510 and a nitrogen male joint are connected to the ends of the chemical hose 500 and the nitrogen hose 600, respectively, and the open distal ends of the chemical male joint 510 and the nitrogen male joint are plugged by a chemical male joint cap (not shown) and a nitrogen male joint cap (not shown), respectively. The operator pulls the chemical hose 500 and the nitrogen hose 600 in this state out of the tank car, removes the above-mentioned male connector cap manually, and then rests on the resting member 151 of the resting portion 150 inside the frame 120, as in the state of fig. 10 and 12. Of course, it may be arranged to automatically remove the male cap by a male cap removing unit (not shown).

As described above, when the chemical hose 500 and the nitrogen hose 600 are rested on the resting member 151 of the resting portion 150 to become the state of fig. 13, the resting sensor 159 senses the normal resting thereof. In this state, the operator grasps the handle portion 156 and pushes forward, the fixing pin 154 is inserted into the fixing pin insertion portion 535, and the chemical hose 500 and the nitrogen hose 600 are fixed to the placement portion 150. If the lock is properly secured, the lock sensor 158 can sense the lock.

At this time, the chemical female joint cap (not shown) covering the end of the chemical female joint 210 and the nitrogen gas female joint cap (not shown) covering the end of the nitrogen gas female joint are automatically removed from the chemical female joint 210 and the nitrogen gas female joint by the female joint cap removing unit (not shown).

In this state, the moving unit 160 is driven, the chemical hose 500 and the nitrogen gas hose 600 linearly move forward, and the chemical male joint 510 and the nitrogen gas male joint are coupled to the chemical female joint 210 and the nitrogen gas female joint, respectively, so that the chemicals can be transferred.

As described above, although the preferred embodiments of the present invention have been described in detail, the present invention is not limited to the embodiments described above, and various modifications are possible within the scope of the patent claims, the detailed description of the invention, and the drawings, and the present invention also belongs to the present invention.
