Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a connector closing device for an automatic clean-

The present invention relates to an automatic clean-connection apparatus for temporarily connecting a transfer line from a transfer tank to a storage tank to use a liquid toxic chemical (hereinafter, referred to as a chemical) in a manufacturing process, When the chemical connector is connected to the male connector formed on the feeding pipe and the female connector of the automatic clean connector, the female connector is securely fastened. When the chemical transfer is completed, the chemical connector is closed and sealed To a connector closing device of an automatic clean connector.

As is well known, semiconductor and LCD manufacturing plants use many types of liquid chemicals. These chemicals are mainly carried in tank lorries and transferred to specific storage facilities (tanks) of factories.

The above-mentioned chemicals are required to have an extremely high level of leakage prevention measures in all aspects of transportation, transportation and use, and there is a problem in that a chemical which is a poisonous substance in a leakage accident causes a lot of social cost loss in life- Toxic chemical leakage has already become a social issue, and such a chemical spill has a problem of causing high cost of disaster prevention treatment and damaging the corporate image.

Especially, when liquid chemical, which is a poisonous substance or a dangerous substance, leaks out of the factory, it is spread to environmental pollution and secondary damage, so its handling should be very sophisticated and strictly done.

In order to safely transport the chemicals, such as the above-mentioned dangerous substances, a cargo handling device equipped with an automatic clean quick coupler device (hereinafter referred to as ACQC) is suitable for mass transfer from the conveying tank to the storage tank of the factory. And the ACQC is installed in the outer wall of the factory by a distance of 1 to 2 m (blocked by a partition wall) to perform the transportation operation.

This can be regarded as a countermeasure to prevent the leakage of the factory outside by holding the effluent chemical in the factory in case of a leak accident. However, the problem of leakage can not be solved only by such a barrier facility, and at the same time, the operator directly connects the transfer hose of the tank to the ACQC There is a problem in that it is difficult to prevent the risk of harming the safety of the worker due to the manual operation of fixing and disassembling and recovering and there is a problem that it is difficult to operate due to heavy weight of the male connector combined with the chemical hose and hose end, There is a problem that much care is required to prevent the number of erroneous insertion.

A description will be given of a conventional technique in which the problem of manual operation is partially improved.

A specialized ACQC device has been developed and known for safe and convenient transfer of the chemical.

According to Korean Patent Registration No. 1572537 "Automated fastening system between chemical tank and ACQC unit ", a first male connector provided at the end of a chemical hose for supplying a chemical from the tank to the ACQC unit can be mounted 1 movable unit; A first male connector cap removing means capable of removing the cap of the first male connector with the first male connector held in the first movable unit; A first female connector cap removing means capable of removing a cap of a first female connector provided at a chemical injection port of the ACQC unit; The first movable connector is linearly fed to the ACQC unit in a state where the cap of the first male connector and the cap of the first female connector are removed to fasten the first male connector to the first female connector of the ACQC unit Conveying means; A second movable unit capable of mounting a second male connector at the end of a nitrogen hose for supplying nitrogen for chemical extrusion from the ACQC unit to the tank in a state where the cap is engaged; A second male connector cap removing means capable of removing the cap of the second male connector in a state in which the second male connector is mounted on the second movable unit; A second female connector cap removing means capable of removing a cap of a second female connector provided at a nitrogen outlet of the ACQC unit; A second feed mechanism for linearly feeding the second movable unit to the ACQC in a state in which the cap of the second male connector and the cap of the second female connector are removed to fasten the second male connector to the second female connector of the ACQC unit Way; A first female connector and a second female connector of the ACQC are wrapped around the first female connector and the second female connector so as to prevent the chemical from being scattered and to prevent external contamination when the chemical leaks at the first female connector and the first female connector of the ACQC unit A clean booth provided with a shutter that is opened only when the first movable unit and the second movable unit enter or return to the ACQC unit; And a second male connector cap removing means, a first female connector cap removing means, a second female connector cap removing means, and a second female connector cap removing means. 2 conveying means and a clean booth inside the ACQC unit so that the ACQC unit can be disposed in front of the ACQC unit.

According to this prior art, a plurality of fastening units for transferring two kinds of chemicals are formed, a male connector is mounted and fixed to the movable unit, the movable unit is linearly moved, inserted and fixed in the ACQC female connector at the opposite position, And the male connector provided at the end of the tank hose is linearly moved toward the ACQC female connector at the opposed position while being mounted on the cradle, so that the male connector is forcibly inserted into the female connector.

The cradle for mounting and fixing the male connector is difficult to grip the male connector to be inserted into the female connector so that external force such as tension is applied to the female connector.

In other words, the female coupling tolerance is formed extremely close to 0.25 mm to 0.4 mm or less in consideration of the chemical leakage, and it is possible to prevent the unevenness in the horizontal transfer process, The male and female connectors spaced apart from each other can not be inserted exactly within the clearance.

If unequal insertion is unstable, ACQC durability may be shortened due to eccentric sealing damage, uneven wear, etc., which may shorten the life span and increase the risk of leakage.

In addition, in the conventional open / close structure of the female connector hole, the cylinder holding the sealing cap and the cylinder for pulling out the sealing cap in the gripped state are respectively formed, the cap is removed and the removed cap is transferred to the correct position and inserted into the cylinder drive And the cylinder for gripping the cap is driven in the home position, which is structurally complicated and has a disadvantage that the frequency of the sealing cap is high.

11. The gripping of the male connector 4 by the gripping device 2 is performed by setting the intervals between the grippers 241 and 231 to grip the flange 41 provided on the male connector and two surfaces of the ring 43, Considerable load is taken into account when considering the weight of the male connector and the transferring chemical, and the male and female connector insertion tolerances are very small, so that the male connector gripped for the insertion of the correct male connector functions to firmly grip the male connector.

13 to 17 In operation, the present invention provides the first to third insertion of the male connector.

In the first pulled-in state, the two grippers 231 and 241 are spaced apart at regular intervals and a part of the suspending ring 43 of the male connector 4 is partly inserted into the hole of the female connector 5, The gripper 231 can not be inserted by the gripper 231 when the gripping cylinder 231 of the gripping unit 23a contacts the surface of the ACQC 230. Therefore, The compression spring 279 is compressed by the backward distance of the joint rod, so that the gripper 231 is maintained in the gripped state and the second drawing is performed.

In the first and second pull-in operations, the portion of the male ring 43 of the male connector is relatively small in comparison with the diameter of the opening of the female connector 5, so that the insertion clearance is large.

However, in the process of releasing the gripper 231 after the second pull-in and finally making the third pull-in, the tolerance of the female and male connectors becomes extremely small (tolerance of 0.2 to 0.5 mm, The self-aligning block 26 releases the state of restraint of the male connector to form a clearance, so that a degree of freedom is relatively given between the male connector and the female connector.

In order to impart the degree of freedom, a clearance is formed between the flow cylinder 262 and the caulking block 264 in the automatic caulking block 26, and a groove is formed in a part of the caulking block 264, Therefore, when the flow cylinder expands, the clearance through the steel ball is constrained to come into close contact with the coarse block, and in the opposite case, clearance is generated between the coarse block and the free block.

When the gripping unit 24 having the degree of freedom is further pushed and inserted, the gripping cylinder 230 is pushed to the position where the gripping cylinder 230 can not retreat to the side of the joint block 272, thereby achieving complete arm / thread engagement.

If it is determined that the insertion is impossible due to the chemical key system inconsistency of the female and male connectors in the operation step 16, mechanical resistance is generated, and by detecting the increase in the rotational torque of the motor of the front and rear drive unit 25, System stop due to inconsistency, return to the home position, and alarm fermentation.

When the front and rear drive unit is formed of a pneumatic cylinder, it can be detected by an increase of the forward force by a load cell (not shown) for detecting a resistance force, and measures such as system stop are taken.

The subsequent action is clear and inverse to the process described above.

The construction and operation of the present invention have been described with reference to the chemical transport structure of the 50A standard in which a plurality of grippers are formed. Considering this description, as shown in FIGS. 1 and 2, The structure and operation of the nitrogen transfer structure are also the same, so that the explanation thereof is omitted.

As described above, the present invention solves various problems required in the solution means of the above-mentioned problems and achieves the object.

Finally, according to the present invention, the male connector holding unit considering the slight tolerance in the male and female connector inserting process is imparted with the degree of freedom and, in the case of the male connector of 50A standard, And it is very important that the degree of freedom by the caulking block and the gripper gripping position of the flange and the suspending portion are very important and the structure specified by the claims is only an example It will be understood that various modifications may be made by those skilled in the art, and such modifications fall within the technical scope of the present invention.
