Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a hot water isostatic pressurizing device, and more specifically, it is capable of pressurizing a pressurized object into a reaction vessel without being hindered by steam rising from hot water. This invention relates to a hot water isostatic pressurizing device that can be loaded or unloaded and has good workability.

[Prior Art and its Problems] Conventionally, there is an isostatic pressurizing device as a device for manufacturing a multilayer circuit board formed by laminating a plurality of circuit boards, for example.

This isostatic pressurization device is placed in a tank containing hot water.

A pressure vessel is immersed so that the opening is located above the surface of the hot water, and the opening of the pressure vessel is hermetically sealed and a pressurized object is placed on the surface thereof. A plurality of circuit boards housed in a pressure vessel immersed in hot water in a tank are pressurized on one side by pressurizing pure water into the pressure vessel. This is now being integrated.

However, the conventional isostatic pressurizing device has a structure in which the lid moves directly relative to the opening, thereby attaching the lid to the opening and removing the lid from the opening. Therefore, when placing a pressurized object on the rack attached to the bottom of the lid, not only is the steam from the hot water inside the pressure vessel coming into contact with the worker's hands, which is dangerous, but also the rising steam may impair work efficiency. There are problems with bad things.

In addition, when molding a pressurized object by increasing the temperature of hot water,
The adverse effect of this steam on workability is still significant.

This invention was made based on 1t1/19.

That is, an object of the present invention is to provide a hot water isostatic pressure pressurizing device that can prevent a decrease in work efficiency due to steam generated by hot water in one reaction vessel.

[Means for solving the above-mentioned problems] The IF of this invention for solving the above-mentioned problems is as follows:
As shown in the figure, the pressure vessel 5 is immersed in hot water 3 in a tank 4 so that the opening 2 through which the pressurized object 1 is taken in and taken out is located above the liquid level of the hot water 3. The pressurized object 1 is stored in the rack 7 attached to the lower surface of the 46 that is airtightly stacked against the opening 2, and the pressurized object 1 is stored in the reaction vessel 5 and hot water is pressurized. , in a hot water isostatic pressurizing device for press-molding this pressurized object l.

J! This hot water isostatic pressurizing device is characterized in that: is provided with a four-swivel device 9 for rotating the lid 6 to a position above the opening 2 and to other positions.

The elevating device 8 may be, for example, an elevating cylinder that is connected to the lid 6 via a support member and has a piston that can be reciprocated using air pressure. However, the driving of the piston in the lifting cylinder is not limited to pneumatic pressure, but may also be hydraulic. Furthermore, as long as the lid can be raised and lowered in any way, other configurations using electric motors may be used. Also good.

The lid rotating device 9 can rotate the lid 6 raised above the opening 2 by the lid lifting device 2+18 between the upper direction of the opening 2 and a position other than that position. For example, it may be configured with a rotary actuator that can rotate the lid 6, which has been raised to the top dead center by the lid lifting device 8, using air pressure, for example. A rotary actuator may be used instead of a rotary actuator.

When the lid lifting device 8 and the lid rotating device 7!9 are provided,
When loading the pressurized object 1 into the pressure vessel 5 containing hot water 3, if 46 is positioned at a position other than the I- side of the opening 2, steam flowing from the opening 2 can be The pressurized object 1 can be placed on the rack 7 without being hindered. Rack 7
After placing the pressurized object 1 on the holder, the four-turning device 9 is driven to rotate the lid 6 to one side of the opening 2, and then the lid lifting device 8 is driven to lower the lid 6. As a result, the rack 7 is placed inside the pressure vessel 5 and the rack 6 is attached to the opening 8112. In this way, the operator can place the pressurized object 1 on the rack 7 without being hindered by the steam of the hot water in the pressure vessel 5, and without encountering danger from the steam. It can be housed in the pressure vessel 5. After the pressurized object 1 is press-molded, the press-molded product can be taken out by the reverse procedure to the above.

In addition, in order to simplify the work when attaching 46 airtightly to the opening 2 of the pressure vessel 5, JI: In order to eliminate the difficulty of work caused by the evaporation caused by the hot water 3 in the tank 4, A first through hole 10 that penetrates in the diametrical direction is provided on the circumferential surface of the pressure vessel 5 near the opening 11 2, and the axis coincides with the first through hole 10 when the cover 6 is attached to the opening 2. A second shell through hole it is provided along the diameter direction on the circumferential side of the bottle 6, and the bottle 12, which is connected to an appropriate driving means 13, for example, a cylinder driven by pneumatic pressure, can be moved in a reciprocating manner to the side of the bottle 6. It is preferable to insert it into the eleventh through hole IO and the second through hole 11.

In addition, in order to prevent even the slightest reduction in work efficiency caused by steam flowing from the hot water 3 in the tank 4, it is necessary to improve the liquid level of the hot water 3 near the inner peripheral surface of the tank 4. It is preferable to provide cooling means, such as a flexible pipe 13, for circulating a refrigerant.

If this hot water isostatic pressurizing device is used to integrally laminate multilayer circuit boards, the hot water 3 is as follows:
Preferably it is pure water.

When the lower end of the overlapping support member 31 is connected to the piston rod of the lifting cylinder 32, one end of the support member 31 is connected to the rotary actuator 33.

The rotary actuator 33 switches the first switching valve 34 and rotates the straight support member 31 with the supplied air pressure under, for example, the AI valve state, thereby opening the lid 27 and opening the [-] portion 25. iJ! The opening 251 is rotated from the avoided position to one position, and the first

The lifting cylinder 32 is connected to a second switching valve 36 via two air supply/exhaust pipes 35 that supply and exhaust air to two air chambers separated by a piston plate in the cylinder. /J When the switching valve 36 is in the A2 type FE, the piston is in the 1st position, so that the position 27 is in the 1st position and the 2nd position is in the 1st position.
When the 9-way switching valve 36 is in the 82 state, the movement of the piston is stopped, and when the second switching valve 36 is in the C2 state, the piston descends and 427 is installed in the open 11 section 25. . +iii It goes without saying that the F dead center of the piston is adjusted to the position where the lid 27 is attached to the opening 25.

Also, on the circumferential surface of the L portion of this pressure vessel 23, r is provided in the diametrical direction.
A closure pin 38 passes through the first through hole 37.

A second through hole 39 is formed on the circumferential side of the drawer 27 so as to correspond to the first page through hole 37 when the :427 is attached to the opening 25.

The closure pin 38 is coupled to -4 of the piston rod of the water moiety moving cylinder 40, which is a reciprocating mechanism,
The other end of the piston rod is a cylinder 40 for moving wood.
Connects to the piston inside.

This piston divides the inside of the horizontally moving cylinder 40 into two chambers, and air is supplied and exhausted to each chamber via a supply and exhaust pipe 41. This air supply and exhaust is performed by the third switching valve 42. For example, when the third switching valve 42 is in the A3 state, the closure bin 386 moves in the direction in which it is removed from the first through hole 37, and the third switching valve When 42 is in the state of 83, the horizontal movement of the closure bin 38 is stopped, and when the third switching valve 42 is in the state of 03, the closure bin 38 moves forward in the direction to be inserted into the first through hole 37. .

In addition, in FIG. 2, 43 indicates the first switching valve 34, the second switching valve 36, and the third switching valve 42.
44 is a biasing member such as a spring, 45 is an air supply pipe, and 46 is a solenoid that drives the
The symbol shown is the intake pipe.

In addition, near the inner circumferential surface of this tank 22 and above the liquid level of the hot water 21, a coiled flexible pipe 47 is arranged.

Further, an introduction pipe 51 having an opening at one end near the bottom surface of the pressure vessel 23 is attached to the pressure vessel 23, and this introduction pipe 51 is branched in the middle, and the opening of one branch pipe is connected to the booster pump. 50 and the opening of the other branch pipe is connected to the circulation pump 49 via a solenoid-driven valve 52 in the middle. Furthermore, the introduction pipe 51 between the circulation pump 49 and the valve 52 is branched into a supply pipe 54 which opens at one end into the tank 22 via a solenoid-driven on-off valve 53. are combined.

Note that 55 is a drain valve for removing water pressure within the pressure vessel 23.

Is this hot water isostatic pressure pressurization device configured as follows? The action of 0 will be explained according to the procedure of pressure molding and cutting of a pressurized object.

Put a predetermined amount of wood, especially pure water, into the tank 22, and turn on the heater 24.
This water is heated to a predetermined temperature of 1f80° C. as hot water 21.

As an initial state, the first switching valve 34 is set to the state 81, the tom 27 is set to a position retracted from above the opening 25, and the closure bin 38 is also set to a position retracted from the opening 25.

Next, the solenoid is driven to open the valve 52 and the circulation pump 49 is driven to open the discharge pipe 48 and the inlet pipe 5.
Hot water 21 in M922 is introduced into pressure vessel 23 via 1. When the circulation pump 49 continues to be driven, the hot water 21 is supplied into the pressure vessel 23, and eventually overflows from the first through hole 37, and the overflowing hot water 21 returns to the tank 22. In other words, WU ring pump 49, discharge pipe 48
The hot water 21 is circulated between the tank 22 and the pressure vessel 23 by the circulation mechanism including the introduction pipe 51. By continuing to circulate the hot water 21, the pressure vessel 23 is heated from inside and outside the pressure vessel 23, and reaches a predetermined temperature, for example, 80°C.

When the pressure vessel 23 reaches a predetermined temperature, the circulation pump 49 is stopped and the valve 52 is closed.

Then, a plurality of circuit boards, for example 30 circuit boards, are placed in a bag and placed on the rack 26. Since this loading operation is performed in a position where the lid 27 and the rack 26 are evacuated from the opening 25, it can be carried out smoothly without being affected by the steam rising from the opening 25.

First! By switching the /J switching valve 34 to the AI state and sending air pressure to the rotary actuator 33 via the supply/exhaust pipe 35, the vertical support member 31 is rotated, thereby horizontally rotating 427, and the lid 27 is rotated. is opening 2
When reaching the upper position of 5, the first switching valve 34 is set to the BL state and the rotary actuator 33 is stopped, thereby stopping the water movement of the lid 27. At this time, the water f@ of the lid 27 and The rack 27 is located on one side of the opening 25. Next, set the 21A switching valve 36 to the state of C2!
E, and drive the Z lowering cylinder 32 downward to bring the ink 27 to the opening i''825.

When the opening 25 reaches 427, the second switching valve 36 is set to the position 82, and the upward movement of the lid 27 is stopped.
- Set the third switching valve 42 to the C3 state and drive the water moth moving cylinder 40 to move the closure bin 38 horizontally, thereby causing the closure pin 38 to pass through the first through hole 37 and the second through hole 39. Then, the lid 27 is airtightly and securely attached to the opening 25. At this time, the rack 26 is housed within the pressure vessel 23.

The previous work of attaching the 427 to the opening 25 and loading the pressurized object into the pressure vessel is all done automatically, so the operator can avoid being burned by the steam rising from the opening 25. There is no risk of injury, and the work can be extremely safe.

Thereafter, the boost pump 50 is driven to force the hot water 21 in the tank 22 into the pressure vessel 23 via the discharge pipe 48 and the introduction pipe 51. Hot water 21 is pressurized into the pressure vessel 23 until the pressure reaches a predetermined pressure.

By press-fitting the hot water 21, the plurality of circuit boards arranged on the rack 26 are isotropically pressurized at a predetermined temperature and molded into an integrated circuit board.

After the pressure inside the pressure vessel 23 reaches a predetermined pressure, the boost pump 5
0 and open the on-off valve 53.
By driving the circulation pump 49, the hot water 21 in the tank 22 is circulated into the tank 22 via the supply pipe 54. As a result, the hot water 21 in the tank 22 maintains a uniform temperature distribution without staying in the tank 22 and causing a temperature gradient.

While the boost pump 50 is stopped, the pressure vessel 23 is
After maintaining the pressure inside the pressure vessel 23 at a predetermined pressure for a certain period of time, the drain valve 52 is opened to release the water pressure inside the pressure vessel 23.

Third! /J switching valve 42 is set to the A3 state, and the water movement cylinder 40 is driven to move the closure bin 38 backward and remove it from the second through hole 39.

When the third switching valve 42 is set to the shape 71 of B3 and the closure pin 38 is brought to the initial state, the second switching valve 36
1. Drive the descending cylinder 32 to remove 7i27. 427 reaches the 1-dead center, the second switching valve 36 is set to the state 82, and
The first switching valve 34 is set to 01, the lid 27 is rotated in the opposite direction from the previous time, and the first switching valve 34 is set to Bl, so that '427 is retracted from the opening 25 to l.

A 30-layer integrated circuit board is taken out from the rack 26 and obtained.

Note that steam rises from the hot water 21 in the tank.

On the inner surface of the tank 22, above the liquid level of the hot water 21, there is a flexible pipe 47 through which a refrigerant circulates, so that the air above the liquid level is cooled by the flexible pipe 47. The rising steam is cooled by this cooled air or by the flexible pipe 47. The steam condenses and returns to hot water 21. Therefore, the steam rising from the hot water 21 does not flow out of the tank 22, and the steam rising from the hot water 21 does not flow out of the tank 22, and the steam rises from the rotary rotary actuator 33 to the third switching valve 34, 36.
42, etc. and other parts and equipment will be adversely affected by qi! j
Also, the liquid level 1- of the hot water 21 in the tank 22
Even if there is a problem with the water, the amount of damage is small, so it is necessary to accurately observe the hot water 21 or the various members and parts in the tank 22 from above the tank 22 without being obstructed by steam. I can do it.

Step 1-2 below is step 1 for molding the multilayer circuit S board.

According to the apparatus of the embodiment, it is possible to perform isostatic pressure molding of a pressurized object, such as a multilayer circuit board, under high-temperature island pressure with good workability without being hindered by steam from hot water.
