Description

Male connector holding unit of chemical automatic supply apparatus

This document relates to the male connector holder of the automatic chemical feeder, and in particular, it relates to the male connector holder of the automatic chemical feeder that aligns the male connector and mounts it with the female connector accurately and precisely.

In general, various types of chemicals are used in companies that manufacture semiconductors, semiconductor devices, LCDs, OLEDs, pharmaceutical companies, paint companies, etc. .

These chemicals are transferred from the chemical tank of the tank lorry stopped outside the building to the chemical storage tank installed inside the building, and then transferred from the chemical storage tank to the chamber where the unit process is performed. is made of Conversely, there are cases where chemicals are transferred from a chemical tank to a tank lorry.

Currently, an automatic chemical feeder called ACQC unit (Automatic Clean Quick Coupler Unit) has been released and used. Here, the chemical storage tank is usually provided inside the building, and the ACQC unit serves as a relay supply between the chemical tank of the tank lorry outside the building and the chemical storage tank inside the building. Specifically, the ACQC unit is configured to include a chemical male connector holder and a chemical female connector, and automatically moves the chemical male connector holder to the chemical female connector by a transfer means. The connector can be inserted and fastened to the female connector. Due to this, the chemical can be safely supplied without the worker being exposed to the chemical.

1 is a view for explaining an aspect of a general ACQC unit. 1 illustrates Korean Patent Publication (Registration Publication No.: 10-1779493, automatic chemical supplying device). As shown, the chemical automatic supply device (1000, ACQC unit) includes a mounting unit 100 ′, a housing body 200 , a housing for transport 300 , a transport unit 400 , and a female connector 500 . can be included.

One end of the transfer unit 400 may be inserted into the opening 601 formed in the wall 600 . The wall 600 refers to a wall constituting the building, and the opening 601 is formed in a shape that is perforated so that the outside and the inside of the building communicate with each other.

When the operator seats and fixes the male connector 20 to which the chemical hose 700 is connected to the mounting unit 100 ′, the mounting unit 100 moves forward by driving the transfer unit 400 . Thus, the male connector 20 is inserted into the female connector 500 . The transfer unit 400 is composed of one or more stages and a driver, so that the mounting unit can slide forward and backward on the stage.

In general, the nitrogen hose 800 is also connected to the chemical automatic supply device 1000 together with the chemical hose 700, and by supplying nitrogen (N2) to the tank lorry, the supply of the chemical can be accelerated by pressurization.

2 is a view for explaining a cross section of a male connector and peripheral parts. As shown, the male connector 20 is divided into a head region 20-1 of the male connector inserted into the female connector and a neck region 20-2 of the male connector fastened by a buffer flange. can The buffer flange 30 is fastened with the hose flange 40 by a plurality of bolts and nuts, so that the chemical is discharged to the outside of the male connector through the nozzle of the hose (not shown) and the male connector connected to the hose flange 40 has been

However, due to the problem of the male connector itself or the connection problem between the buffer flange and the hose flange, the central axis of the male connector (A, solid line) and the central axis of the hose flange (B, dotted line) may not coincide. However, due to this, the central axis of the male connector and the central axis of the female connector do not coincide with each other, so that the male connector cannot be accurately inserted into the female connector, so that a smooth chemical supply may not be achieved, and a collision between the male connector and the female connector It can cause damage and this can lead to major accidents. If there is a problem in fastening by a plurality of bolts/nuts, the separation distance (d, d') between the buffer flange and the hose flange will be different (d ≠ d').

3 is a view for explaining a state in which the central axis of the male connector and the central axis of the hose flange do not coincide. Fig. 3 (a) is a view in which the male connector is lowered, and Fig. 3 (b) is a view in which the male connector is raised upward. As shown in Fig. 3 (a), the male connector goes down (sags) so that the central axis (A, solid line) of the male connector is located below the central axis (B, dotted line) of the hose flange, The central axis (A) of the male connector and the central axis (B) of the hose flange form an angle equal to θ.

Meanwhile, a first key code block 31 may be provided at a lower portion of the buffer flange 30 in order to prevent chemical misinjection. The first keycode block 31 may have a protruding shape or a concave shape as shown. The first key code block 31 may include a first key code (not shown).

In addition, as shown in (b) of FIG. 3, the male connector moves upward so that the central axis (A, solid line) of the male connector is positioned above the central axis (B, dotted line) of the hose flange. The central axis (A) of the connector and the central axis (B) of the hose flange form an angle as much as ф.

The reason why the central axis of the male connector and the central axis of the hose flange do not match is that the male connector is usually made of Teflon, which is easily deformable. However, a part of the head area of the male connector is covered with a Sus material, which has relatively high strength, but the neck area is exposed to the outside with a Teflon material, so bending occurs frequently in the neck area.

In addition, since the neck area is thinner than the head area, there may be cases in which shape deformation occurs in the neck area due to a load due to prolonged use. Also, in some cases, the male connector itself is deformed by dropping the male connector or by external impact. When the buffer flange is connected to the hose flange, the bolt/nut tightening is poor, so the distance between the hose flange and the buffer flange is horizontal. Failure to do so may cause these problems. In addition, when one side of the buffer flange and the hose flange are fastened, if either side is tightened with too much force, one side of the Teflon surface is pressed and a deformation may occur in which the corresponding neck area is stretched. Therefore, it is necessary to introduce a separate structure to solve these problems.

An object of the present invention is to align the male connector so that the central axis of the male connector and the central axis of the hose flange are aligned to ultimately accurately connect the male connector and the female connector.

In order to supply chemicals from one side to the other by connecting between the chemical tank and the chemical storage tank, the male connector is transferred back and forth by the transfer unit in a state where the male connector coupled with the buffer flange is seated, and the male connector stores the chemical The male connector holder of the chemical automatic supply device to be connected to the female connector on the tank side,
