Description

Hoist module for gas auto supply apparatus of gas cylinder

The present invention relates to a hoist module for an automatic gas supply device of a gas cylinder in which a hoist module for up/down semi-automatically up/down wires on which the automatic gas supply module is suspended is installed on the ceiling of a cabinet.

In general, in a semiconductor device manufacturing process, a highly flammable or toxic gas is used according to process characteristics, and this gas is usually contained in a gas cylinder at a high pressure and replaced according to the remaining amount of gas.

That is, when the connector is fastened to the outlet port of the gas cylinder and the pipe disposed inside the connector and the outlet port are in contact with each other, the valve is opened and the gas of the gas cylinder is supplied to the semiconductor device manufacturing process through the outlet port and the pipe. .

As a conventional gas cabinet-mounted module, what is known in Patent Document 1 (Korean Publication No. 10-2019-0014463) is disclosed.

In Patent Document 1, in the spherical type gas cylinder automatic opening and closing device having a cabinet of 800 × 590 (mm) in width × length, it is impossible to install a lift that automatically raises the gas cylinder 60 due to the narrow space, so the second alignment means (130) is designed to apply.

Since the gas cylinder automatic opening/closing device is installed on the left and right sides of the cabinet, one is supplying gas and the other is being replaced and waiting for continuous gas supply.

As shown in FIG. 44, the second aligning means 30 includes an aligner 31 fixed to the bottom surface of the main plate 11 and having two or more aligning pins 31a, and a valve ( The alignment block 32 is detachably fixed to 63 and provided with a positioning hole 32a into which the alignment pin 131a is fitted, and the alignment block 32 is connected to the valve 63 by a fastening member (not shown). It is composed of a fastening plate 33 to be fixed with a).

Therefore, when the main plate 11 descends in a state where the gas cylinder 60 is positioned inside the cabinet, the operator can visually identify the position of the alignment pin 31a and finely adjust the position of the gas cylinder 60 to align By allowing the pin 31a to be inserted into the positioning hole 32a of the alignment block 132, the position of the gas cylinder 60 is aligned.

As shown in FIG. 43, the main plate 11 uses a cylinder, a lifting block, and a pulley disposed on the left and right sides of the main plate 11. When the piston of the cylinder goes up, the main plate 11 goes down and when the piston goes down It is an ascending structure.

Since the elevating structure of the main plate 11 is installed on the outside of one side of the male plate 11, it more protrudes to the side for a certain size of the male plate 11, and in particular, the cabinet is mounted as a pair. It is difficult to fit the horizontal length (800mm) of

In addition, as shown in FIG. 43 , since the main plate 11 ascends and descends on the guide block, movement other than up and down is limited, and the position of the gas cylinder 60 needs to be finely adjusted for alignment.

In addition, there are very many parts for elevating the main plate, such as cylinders, pulleys, and guide blocks.

On the other hand, the gas cabinet-mounted module of Patent Document 2 (Korean Patent No. 10-2112765) is known in the arrangement as shown in FIG.

As shown in FIG. 45, in the gas cabinet-mounted module of Patent Document 2, the end cap part 60 and the connector part 70 are disposed on the rear side, and the gasket parts 81 and 82 are disposed on one side. .

The gasket parts 81 and 82 are composed of a gasket supply part 81 and a gasket delivery part 80 .

The gasket supply part 80 is disposed next to the connector part 70 , and the gasket delivery part 82 is disposed in front with respect to the gasket supply part 81 .

Since the gasket supply unit 81 is disposed on one side of the rear side, it is difficult for the operator to check the supply amount of the gasket with the naked eye (if the gasket is not filled immediately, the operation speed will be slow and it is fatal to the semiconductor process) It is undesirable in terms of maintenance, such as having to manually put your hand into the narrow space at the rear.

On the other hand, since there is no connector plug to block the connector part in the state in which the gas cylinder is not inserted, it is impossible to prevent contamination of the connector part pipe and the gas residue of the gas supply pipe from spreading to the outside.

On the other hand, since the end cap part 60 and the connector part 70 are fixed side by side, they not only occupy a larger space, but also have to move at the same time during rotation or forward/backward transfer, resulting in unnecessary power loss.

Since the outlet port of these prior art is a connector adapted to a hollow male screw, as in the present embodiment, in the case of a solid male screw, it is impossible to fasten with a conventional connector.

That is, as a configuration for separating/fastening the end cap 8 with the end cap tool part 400a receiving rotational power about the x-axis of the connector member 500a, the end cap tool 410a of the end cap tool part 400a is When positioned side by side in series in front of the connector 510a of the connector member 500a, it is the end cap separation/fastening operation position (see FIG. 37), and when positioned in parallel with the left and right sides of the connector member 500a, the connector 510a is the connecting operation position ( 35) is characterized in that it is moved to be disposed.

In addition, due to the nature of the operation of the connector member (500a), the degree of freedom of the ground nut (513a) and the portion of the gland (514a), which should normally protrude forward, are connected to the outlet port (5)/connector plug (610) when the gland (514a) is connected. The grand guide part 515a for giving autonomy so that the nut 513a can enter the inside is implemented.

As shown in FIGS. 28 and 29, the connector member 500a is supported on the upper surface side of the frame 310 by a support plate 501a.

The connector member 500a includes a connector 510a connected to the outlet port 5, a first actuator 530a for transmitting rotational power to the connector 510a, and the connector 510a in line with the outlet port 5.

Substantially, the forward and backward (y) and left and right (x) transfers of the connector member 500a are performed by the first actuator 530a including the connector 510a.

In addition, the connector 510a disposed side by side with the outlet port 5 is a position facing the connector plug member 600/gasket input/discharge member 700 .

The connector 510a has some differences depending on the shape of the outlet port 5/connector plug 610, but in this embodiment, the outlet port 5/connector plug 610 has a male thread formed on the outer circumferential surface of the shaft. Since it is a normal male threaded rod shape, the pipe 511a is linearly slid so that the pipe 511a is pushed in when fastened, and the gasket G is also a donut disc shape hanging on the front surface of the connector 510a.

Of course, in the center of the outlet port 5, an outlet hole through which the gas of the gas cylinder 1 is discharged is formed to be substantially equal to or smaller than the pipe 511a.

As shown in FIGS. 30 and 31, the connector 510a passes through the inside of the reducer 533a and both ends protrude to the outside, and a polygonal hollow part that receives the rotational force of the reducer 533a. (512a), and a grand nut (513a) inserted therein to be rotated along with the polygonal hollow part (512a), and the outlet port (5) or connector plug (610) while being fixed to the outer peripheral surface of one end of the pipe (511a) and a gland 514a disposed inside the gland nut 513a screw-fastened to the gland 514a, and a gland guide part 515a for guiding the gland 514a to be slidable in a straight line with respect to the gland nut 513a.

That is, as shown in Figure 31a, the rear outer circumferential surface of the grand nut 513a is a polygon 513a' coupled to the polygonal hollow part 512a, and is caught by the hooking (512a') of the inner circumferential surface of the polygonal hollow part 512a. It is prevented from further deviating forward.

The grand nut 513a is pushed in from the rear to the front of the polygonal hollow part 512a until it is caught by the locking jaw 512a.

At this time, a separation prevention ring (512a'') is installed at the rear of the polygonal hollow part (512a).

In addition, a nut correction spring 525a is further installed between the separation prevention ring 512'' and the ground nut 512a.

The nut correction spring (525a) serves to correct the eccentricity with the outlet port (5) when fastening/disconnecting.

The grand guide portion 515a includes a ball bush 516a fitted to the other side of the pipe 511a, a ball bush housing 517a fitted to the outer circumferential surface of the ball bush 516a, and the rear surface of the reduction gear 533a body and the ball bush. The connection piece 518a fixed to the housing 517a, the flange 519a installed on the outer peripheral surface of the pipe 511a between the ball bushing housing 517a and the gland 514a, and the ball bushing housing 517a and the flange 519a ) includes a ground return spring (520a) installed between, and a stopper (521a) installed at the other end of the pipe (511a) is caught on the connecting piece (518a).

The stepped portion 517b serves as a seat to which both ends of the grand return spring 520a together with the flange 519a come into contact with each other.

The connecting piece 518a has a hole, a U-shape, or an inverted U-shaped penetrating portion so as not to interfere with the sliding of the pipe 511a.

The flange 519a serves not only as a seat of the grand return spring 520a but also as a shaft that substantially guides the through hole in the reduction gear 533a body.

That is, when the gland nut 513a is forwardly fastened with the cover plug 610 or the outlet port 5, the gland 514a together with the pipe 511a is pushed inward, and the grand return spring 520a is compressed and fastened. When this is released, the gland 514a together with the pipe 511a returns to its original position.

In addition, the tip 511b of the pipe 511a is a fitting protrusion protruding forward from the gland 514a, and a donut-shaped gasket is inserted thereinto.

The gasket seals between the front surface of the gland 514a and the front surface of the outlet port 5 .

In addition, the stopper 521a is to prevent the pipe 511a from being pulled forward by the grand return spring 520a from being separated, and is fixed to the pipe 511a by grabbing both ends of the U-shape.

A sensor 522a for detecting a gasket placed on the tip 511b of the pipe 511a is further installed in the hollow reducer 533a.

In order to guide the grand 514a that requires precision, autonomy and freedom by the configuration of the grand guide unit 515a, there was an LM guide outside the reducer in the past, but space restrictions occur. It can be configured to maximize space utilization, and it is configured to be a guide in all directions by using a ball bush so that there is no need for a separate setting.

The first actuator 530a includes an air motor 531a and a speed reducer 533a for transmitting the rotational power of the air motor 531a to the polygonal hollow part 512a as in the first embodiment.

The reduction gear 533a has an L-shape by removing the power transmission portion of the end cap member 400 of the first embodiment.

The air motor 531a is disposed on one side of the reduction gear 533a as shown in FIG. 29 .

The rotational force of the first actuator 530a rotates the polygonal hollow part 512a and the grand nut 513a.

In addition, when the grand nut 513a is fastened to the outlet port 5, the gland 514a is pushed back to compress the grand return spring 520a.

The third actuator 570a includes a third guide rail 571a installed on the bottom surface of the support plate 501a, and a third guide rail groove block 572a coupled to the third guide rail 571a. It includes a plate 573a and a third air cylinder portion 575a for moving the third movable plate 573a with respect to the support plate 501a.

The third guide rail 571a and the third guide rail groove block 572a are the 3 LM guides, and it is irrelevant even if their positions are changed.

The third air cylinder part 575a includes a third air cylinder 576a installed on the support plate 501a and a third piston 577a for moving the third movable plate 573a.

The second actuator 550a includes a second guide rail 551a installed on the bottom surface of the third movable plate 573a, a second guide rail groove block 552a coupled to the second guide rail 551a, and a reducer ( The second bracket 554a connecting 533a and the second guide rail groove block 552a include a second air cylinder part 555a moving along the second guide rail 551a.

The second air cylinder part 555a includes a second air cylinder 556a installed on the third movable plate 573a and a second piston 557a for moving the speed reducer 533a through the second bracket 554a. include

The second actuator 550a can be made compact as a whole by arranging it in a space in which the reducer portion corresponding to the end cap member 400 of the first embodiment is deleted.

Such a connector member (500a) may be applied instead of the connector member (500) of the first embodiment.

On the other hand, the end cap tool 410a slides along with the advancement (approach) of the connector member 500a by the amount that the end cap 8 is fastened to the outlet port 5 while receiving the rotational power of the connector 510a. , by the amount of the end cap 8 separated from the outlet port 5 by the return force of the end cap tool 410a to slide backward (retreat) together with the connector member 500a.

As shown in FIGS. 28, 29, and 40, the end cap tool part 400a applies the rotational power of the end cap tool 410a arranged in parallel with the connector 510a and the connector 510a to the end cap tool 410a. ), an actuator 450a for the end cap tool that transports the end cap tool 410a back and forth so as to be arranged in parallel/series with the connector 510a, and the connector 510a. and a return actuator 470a for returning the end cap tool 410a.

The end cap tool 410a has a hollow shape as shown in FIGS. 32 and 33, and an end cap tool 1410a fitted to the end cap 8, and a connector tool that receives rotational power of the connector 510a ( 2410a).

On the inner peripheral surface of the end cap tool 1410a, protrusions 1411a protruding inward are provided at predetermined intervals.

That is, as shown in Figure 34 (a), the edge (8a) of the end cap (8) is disposed between the projection (1411a) and the projection (1411a), the side (8b) of the end cap (8) when holding and turning Since the edge 8a of the end cap 8 cannot penetrate by touching the side surface of the protrusion 1411a, the phenomenon that the end cap 8 and the tool 1410a for the end cap are tightly pinched is prevented.

If, as shown in Fig. 34(b), if the inner peripheral surface of the end cap tool 1410a is formed in a hexagonal shape like the end cap 8, the edge 8a of the end cap 8 is on the inner peripheral surface when holding and turning. When the end cap tool 1410a rotates with a strong force when touched, the edge 8a of the end cap 8 digs into the inner circumferential surface and fits tightly. Then, when the end cap tool part 400a is restored (reversed) after fastening again, an error may occur due to resistance.

In addition, an inclined surface 1413a is formed on the protrusion 1411a , and serves as a guide surface to easily enter the end cap 8 .

In addition, the end cap holding part 1415a for holding the separated end cap 8 as shown in FIG. 33 is installed in the end cap tool 1410a.

A magnet or a mechanical method can be implemented as the end cap holding part 1415a, but in this embodiment, it is implemented as a ball 1416a that applies pressure to the side of the end cap 8.

The ball 1416a is disposed immediately behind the protrusion 1411a in the radial direction along the circumference of the end cap tool 1410a, and is pressed by the compression spring 1417a.

After the end cap tool 410a is rotatably fitted to the end cap tool support bracket 2450a, particularly the end cap tool bracket 2453a, a C-ring 1440a is assembled on the outer peripheral surface of the end cap tool 1410a to prevent separation. .

Therefore, the end cap tool bracket 2453a is disposed between the connector tool 2410a and the C-ring 1440a and is not separated even if it rotates.

The connector tool 2410a is a flange type, and is larger than the outer diameter of the end cap tool 1410a.

Such an end cap tool 410a can be replaced when separating/fastening the end cap 8 of a different shape depending on the type of the gas cylinder 1, so it is very excellent in terms of maintenance.

The rotational power transmission unit 430a includes a pin 1430a installed to protrude forward from the front surface of the polygonal hollow portion 512a, and an insertion hole 2430a formed in the connector tool 2410a so that the pin 1430a is inserted. do.

At this time, it is preferable that the insertion hole 2430a is formed as a long hole type insertion hole 2430a which is a tangential direction of rotation as shown in FIG. 29 .

Accordingly, the insertion hit ratio of the pin 1430a into the long hole type insertion hole 2430a is increased, and separation from each other is also facilitated.

The pins 1430a and the long hole-type insertion hole 2430a are disposed along the perimeter at a predetermined interval (eg, at least 120 degrees apart).

The actuator 450a for the end cap tool includes an air cylinder part 1450a for the end cap tool installed on a support plate 350a installed on the frame 310 and an air cylinder part 1450a for the end cap tool while supporting the end cap tool 410a. ) and a first end cap tool LM guide 3450a installed between the upper surface of the support plate 350a and the lower surface of the end cap tool bracket 2450a.

The LM guide 3450a for the first end cap tool is formed by combining the first guide rail 3451a installed on the support plate 350a and the first guide rail groove block 3453a installed on the bracket 2450a for the end cap tool. .

The air cylinder part 1450a for the end cap tool includes an air cylinder 1451a for the end cap tool installed on the upper surface of the support plate 3450a, and a piston 1453a installed to the bracket 2450a for the end cap tool.

The support bracket 2450a for the end cap tool has an L-shape as a whole, and is disposed and installed in front of the plate-shaped end cap tool block 2451a in which the return actuator 470a is installed, and the end cap tool block 2451a. It includes a bracket (2453a) for the L-shaped end cap tool.

According to this configuration, since the end cap tool 410a is always positioned in front of the connector 510a, there is a risk of interference when the gas cylinder is inserted or the connector 510a is repaired.

Therefore, when the end cap tool 410a is parallel to the connector 510a, the cam follower 490a is further included so as not to protrude forward than the connector 510a as shown in FIGS. 27 and 35A .

As shown in FIGS. 36 and 38, the cam follower portion 490a includes a cam follower 1490a protruding downward from the block 2451a for the end cap tool, and a rail 2490a for the cam follower formed on the support plate 350a. ) and an LM guide 3490a for a second end cap tool for guiding forward and backward between the first guide rail groove block 3453a and the block 2451a for the end cap tool, wherein the piston 1453a has the first guide rail groove installed in block 3453a.

The rail 2490a for the cam follower is composed of a curved rail 2491a almost L-shaped and a straight rail 2493a.

The straight rail 2493a is formed in front in parallel with the first guide rail 3451a.

The curved rail 2491a is formed as an outwardly convex arc between at least the first guide rail 3451a and the straight rail 2493a, the starting point being on the same line as the first guide rail 3451a, and the end point being the straight rail It is preferable to connect with the time point of (2493a).

The LM guide 3490a for the second end cap tool has a second guide rail block 3491a installed in the first guide rail groove block 3453a and a second guide rail groove installed on the lower surface of the block 2451a for the end cap tool. Block 3493a is made to be coupled.

Accordingly, when the first guide rail groove block 3453a is pulled toward the rear, when the cam follower 1490a passes along the curved rail 2491a, the second guide rail groove block 3493a with respect to the second guide rail block 3491a. As it moves forward, it naturally crosses the straight rail 2493a and is arranged in series in front of it as shown in FIG. 37 .

The return actuator 470a is a free back cylinder for reversing the end cap tool 410a according to the amount to be separated when the end cap 8 is separated.

That is, the return actuator (470a) is that air is injected only in the backward direction, and is in a no-load state when moving forward.

Accordingly, when the connector member 500a and the end cap tool 410a advance to the outlet port 5, the connector member 500a is in a loaded state and the end cap tool 410a is in a no-load state, and the connector member 500a is moved to the end cap tool. (410a) is pushed.

In particular, the return actuator 470a also functions to reduce the force applied by the connector member 500a to the end cap tool part 400a by half, so that excessive force is not applied to the coupling with the end cap 8 .

Conversely, when the connector member 500a and the end cap tool 410a move backward from the outlet port 5, the connector member 500a is in a no-load state, the end cap tool 410a is in a loaded state, and the end cap tool 410a is connected to the connector. The member 500a is pulled.

When the end cap tool 410a comes to a position where the reversing is completed, the connector member 500a retracts under the load so that the pin 1430a comes out completely from the long hole type insertion hole 2430a.

As shown in FIG. 40, the return actuator 470a includes a back cylinder 1470a installed on the upper surface of the end cap tool block 2451a and a back piston 2470a installed on the end cap tool bracket 2453a. include

The back piston 2470a is installed on the back piston block 2471a coupled to the upper surface of the back cylinder 1470a by the LM guide, and the back piston block 2471 is installed on the end cap tool bracket 2453a.

In addition, a guide bar 3470a for guiding the sliding of the end cap tool bracket 2453a with respect to the end cap tool block 2451a is installed before and after the return actuator 470a.

One end of the guide bar 3740a is guided while being fixed to the bracket 2453a for the end cap tool while being inserted into the guide hole 3742a of the block 2451a for the end cap tool.

The forward and backward movement of the end cap tool 410a is stably guided by the configuration of the return actuator 470a and the guide bar 3740a.

Hereinafter, a method of separating the end cap 8 from the outlet port 5 by combining the connector member 500a and the end cap tool part 400a will be described with reference to FIGS. 35 to 42 .

35 is an initial working state in which the connector 510a of the connector member 500a which faces the end cap 8 in a straight line and the end cap tool 410a of the end cap tool part 400a are parallel to each other.

As shown in FIG. 35A , the end cap tool 410a is disposed slightly behind the connector 510a when viewed from the front, but may be disposed on the same line.

In the initial state of operation, when the piston 1453a of the air cylinder part 1450a for the end cap tool is pulled in the y direction approaching the connector 510a as shown in FIGS. 37 and 38, the second end cap tool LM guide 3490a As a result, the cam follower 1490 rides the curved rail 2491a and crosses the straight rail 2493a in the x-direction, and the end cap tool 410a is placed in series on the connector 510a.

37, when the end cap tool 410a is placed in front of the connector 510a, the third air cylinder part 575a is operated to advance the connector member 500a (x direction), and the pin 1430a is inserted into the long hole type insertion hole. The end cap tool 410a is also advanced (x-direction) while being inserted into the 2430a so that the end cap tool 1410a is fitted to the end cap 8 as shown in FIG. 39 .

Then, the third air cylinder part 575a is switched to a no-load state (intermediate exhaust state), and the polygonal hollow part 512a is rotated around the x-axis through the hollow reducer 533a of the first actuator 530a. The end cap 8 is released from the outlet port 5 as the end cap tool 410a is rotated through the power transmission unit 430a.

At this time, the end cap tool 410a and the connector member 500a are returned together by the return actuator 470a according to the amount of the end cap 8 released.

When the return of the end cap tool 410a is completed, the connector member 500a switches to the load state to return the third air cylinder part 575a to its original position so that the pin 1430a is completely removed from the long hole insertion hole 2430a. out (see FIG. 41).

When the separation of the end cap 8 is completed as shown in FIG. 41, when the piston 1453a of the air cylinder part 1450a for the end cap tool is pushed in the y direction away from the connector 510a, the LM guide 3490a for the second end cap tool ), the cam follower 1490 rides the straight rail 2493a and goes to the curved rail 2491a, and as shown in FIG. 42, the end cap tool 410a holding the end cap 8 is parallel to the connector 510a. It will return to the job completion position.
