This can cause, for example, problems where the semiconductor chip is sealed with, for example, lead frame or circuit Board, chip or peel due to insufficient quantity of applied adhesive, or a short circuit due to the electrically conductive adhesive is applied in excessive amounts.

Taking into account the m above problems, the applicant has proposed a device for release containing a reducing pressure valve for decompression of compressed gas originating from a compressed gas source, a solenoid valve equipped with a timer to control the number decompressional gas passing through it, and wydanie nozzle for the quantitative distribution or delivery of liquid material, which is stored in vitachem nozzle, with gas supplied through the solenoid valve, a device for the release of producing a fixed amount of liquid material through the provision of direct pressure on the surface of the liquid material, which is stored in vitachem nozzle by means of compressed gas, and a buffer tank that stores compressed gas and having a larger internal volume than wydanie a nozzle placed in the middle of the line that extends from reducing the pressure valve to solenoid valve (patent document 1).

In addition, the proposed applicator for applying the material used in the syringe of the PCB through the exhaust nozzle of the compressed air under a predetermined pressure from a regulator which communicates with a source of compressed air in the syringe within a specified time by switching the exhaust valve, and this device includes a pressure chamber with a built-in regulator, kept the Yu received compressed air and feeding the compressed air toward the exhaust valve (patent document 2).

In any of the above devices buffer tank (pressure vessel) is to increase the pressure inside the syringe immediately after opening the valve to release. With this action, the buffer capacity can be obtained a high pressure for a shorter production time than the time of the release device, not including the buffer capacity. Accordingly, the pressure required to ensure the required performance can be obtained in a shorter time, and the release operation can be performed at higher quantum.

An embodiment of the invention

As illustrated in figure 1, by way of example, the device of the present invention includes, as main components, a reservoir 8, which stores the liquid and is connected with an outlet opening through which produced fluid, reducing the pressure valve 11 for decompression of the compressed gas supplied from the compressed gas source 1, buffer tank 21 that stores compressed gas and having a greater internal volume than the reservoir 8, the exhaust valve 9 for custom installation or breach of messages between reducing the pressure valve 11 and the reservoir 8 through the buffer tank 21 and the timer 10 for opening and closing the exhaust valve 9 and the control passing what kolichestvo decompressional gas.

When the device of the present invention is inoperative, the space 24 through which pressure is applied to the liquid 20 stored in the tank 8, opens in the atmospheric environment and the resulting liquid is released. On the other hand, when the device is in operation (output) condition, the liquid 20 is discharged from the nozzle 13 by actuation of the exhaust valve 9 for the message buffer tank 21 with the tank 8, slicing the space 24 from the atmospheric environment and then feeding air into the tank 8 from the buffer tank 21 so as to increase the pressure in the space 24. In this case, when air is supplied from the buffer tank 21 into the space 24, the pressure in the pipe 4 is temporarily reduced, thus causing a ripple. This problem becomes more significant when the release liquid 20 is repeated and the amount of space 24 is increased.

In this regard, the device of the present invention, the reduced pressure in the flow path (flow path located on the lower stream side), indicating the buffer tank 21 and the tank 8, is prevented not only by providing a buffer tank 21 having a relatively larger volume than the reservoir 8 in the known device, but also to increase the flow resistance of the flow path, telling buffer tank 21 and the reservoir . Specifically, in the device of the present invention disclosed here is formed a flow path located downstream from, for example, a buffer tank 21 so that its inner diameter is partially less than the minimum inner diameter of the flow path located upstream from the buffer tank 21. In more detail, throttle (for example, a narrower area or hole) is located in the pipe 4, the exhaust valve 9 and the pipe 7, which constitute the flow path between the buffer tank 21 and the tank 8, to thereby provide an area having a smaller diameter than the internal diameter of the pipeline 3, reducing the pressure valve 11 and pipe 2, which constitute the flow path between the buffer tank 21 and the compressed gas source 1. It is important that the flow resistance of the flow path located downstream from the buffer tank 21, significantly more than the flow resistance of the flow path located upstream from the tank 21. This feature can also be implemented, for example, by setting the equivalent hydraulic diameter and/or inner diameter of the flow path, on the side downstream, fully a smaller internal diameter(s) of the flow path, on the side above the stream.

With the above structure during the period before reducing the providing of the valve 11 and the compressed gas, reducing the pressure inside the buffer tank 21 can be reduced, while the pressure can be stably applied to the space 24. In other words, in the device of the present invention as a flow resistance on the supply side of the buffer capacity is large enough, the speed of the air supplied to the buffer capacity, relatively higher air speed obtained from the buffer capacity. As a result, the decrease of pressure in the flow path located downstream from the buffer tank 21 can be minimized.

The flow resistance of the flow path located downstream from the buffer tank 21, is adjusted to the optimum when considering the relationship between the rate at which compressed gas can be fed into the tank 8, and a decrease of pressure in the flow path, through which the compressed gas is fed into the reservoir for the liquid.

Additionally, the length of the pipe 3 is preferably set shorter than the total length of pipelines 4 and 7 (for example, not more than 2/3 or 1/2). Due to the installation of gas under controlled pressure can be more smoothly filed, when the exhaust valve 9 opens.

Figure 2 is a graph showing the time variation of the gas pressure in the pipe 4 connecting the exhaust valve 9 and the buffer tank 21. Curve C represents the change giving the value of gas in the known device. As can be seen from curve C, the time TC passes before the gas pressure in the pipe 4 is returned to the initial state by using the exhaust valve 9. Curve b represents the change of gas pressure in the device including the buffer capacity. Although some improvement is obtained in such a device, a pressure change to the return gas pressure in the pipe 4 in the initial state depicted a relatively steep curve. Curve a represents the change of gas pressure in the pipe 4 of the device of the present invention. Curve and confirmed that the reduction of pressure in the pipe 4 is minimal.

Figure 3 is a graph showing the time variation of the gas pressure inside the buffer tank 21. Figure 3 curve (C) represents a change in the gas pressure in the known device, the curve (b) represents a change of gas pressure in the device including the buffer capacity and the curve (a) represents a change of gas pressure in the device of the present invention. Thus, it is confirmed that there is a definite correlation between the change in gas pressure in the buffer tank 21 and the change in the gas pressure in the pipe 4.

As shown in figure 2 and 3, so as to reduce pressure in the flow path for the compressed air in the tank 8 can be minimized to eliminate the defenders of the present invention, distribution or issuance of the liquid material can be adjusted with higher accuracy than in known devices.

According to the present invention having the above construction, the internal volume of buffer capacity can be set in the range from 1.5 times to less than 10 times the volume of the tank. Note that when the device size is not the problem, the ratio of the volume of the buffer tank and the tank can be set in the range from 10 to 100 times. Additionally, the buffer capacity and/or reducing the pressure valve may(may) be posted(s) in the set.

The details of the present invention will be described below in connection with the execution, but the present invention is in no way limited to, the following variants of execution.

Option run 1

Outlet options for performing 1 is made, as illustrated in figure 1, it includes, as main components, a reservoir (syringe) 8 that stores the liquid and is connected with an outlet opening through which fluid is produced, reducing the pressure valve (regulator) 11 for decompression of the compressed gas supplied from the compressed gas source 1, buffer tank 21 that stores compressed gas and having a greater internal volume than the reservoir 8, the exhaust valve 9 for custom installation is or cropping messages between reducing the pressure valve 11 and the reservoir 8 through the buffer tank 21, and the timer 10 for opening or closing the exhaust valve 9 and passing control number decompressional gas. Pipelines 2-4 and 7, connecting these components have the same diameter selected from a range of 1-10 mm, the length of the pipeline 3 is set shorter than the total length of pipelines 4 and 7. Practically, in the example described here, the length of the pipeline 3 is set to several tens of centimeters, while the total length of the pipes 4 and 7 to 1 m or longer, however, depending on the schema of the pipelines, etc.

Tank 8 in this embodiment is 1-500 cm3and the volume of the buffer tank 21 is in the range from 1.5 times to less than 10 times the volume of the tank 8. Wydanie nozzle, comprising a reservoir 8 and the nozzle13, is set to, for example, XYZ-robot.

In the device of this option is run, for example, a gas pressure of 3 kg/cm2is supplied from the compressed gas source 1, while the gas pressure is regulated to reduce the pressure valve 11 and is reduced to a pressure selected from a range from 0.3 to 1.0 kg/cm2.

The device in this embodiment is made so that the diameter of the pipe on the supply side of the buffer tank 21 is smaller than the diameter of the pipeline on its side of the feeder. More specifically, the narrowed area, is within the pipe diameter of 1 μm-5 mm, provided in the exhaust valve 9, which is located on the supply side of the buffer tank 21.

In the device of this option is run with the above structure, the liquid material produced by the implementation stages of the exhaust valve 9 and reducing the pressure valve 11 in a consistent manner. Liquid material distribute or issue, for example, by performing the following steps:

i) the stage at which open the exhaust valve 9, resulting in a buffer tank 21 appears in the air and the pressure in the buffer tank 21 decreases

ii) the stage at which force reducing the pressure valve 11 to detect a decrease in pressure in the buffer tank 21 and run the pressure in the buffer tank 21, and

iii) the stage at which increasing the reduced pressure in the buffer tank by triggering reducing pressure valve.

On the above stages may occur a difference of time before reducing the pressure valve 11 begins to operate, i.e. the time delay between steps i) and ii). To minimize this time delay effectively increase the flow resistance at the lower stream side buffer tank 21. Also, it is preferable to set the length of the flow path, telling buffer tank 21 and reducing the pressure valve 11 with each other, as short as possible

Option run 2

Outlet options run 2 is performed, as illustrated in figure 4, it includes a second buffer tank 22, and the second reducing pressure valve 12 and the pipes 5 and 6 in addition to the exhaust device scenarios 1.

Using design scenarios 2, in which the buffer capacity is provided in multiple, pressure changes caused by mechanical operations control pressure reducing pressure valves 11 and 12 can be prevented from exposure to the liquid material inside the tank 8, and therefore, may be filed more stable pressure. This point will be described in detail below.

In General, reducing the pressure valve operates to control the primary pressure, which is introduced into the reducing pressure valve, reducing the pressure inside the valve to transfer the desired secondary pressure. In order to create a stable secondary pressure with high precision, however, stable primary pressure preferably is introduced into the reducing pressure valve. The reason is that if the primary pressure is introduced into the reducing pressure valve is changed, the secondary pressure also changes, thereby causing a change in pressure applied to the fluid in the tank. So the m way stabilization of the primary pressure is an important factor from the viewpoint of stabilization of pressure, which acts on the liquid in the tank. In other words, the primary pressure can be stabilized by providing the serial reducing the pressure valves.

In the case, including serial reducing the pressure valve when changing the pressure supplied from upstream, gas (air) is first fed to the primary side of the reducing pressure valve on the side upstream, and then reduced the pressure comes from the secondary side to reduce the pressure valve on the side of the lower stream. At this time, the pressure coming from the secondary side to reduce the pressure valve on the side of the lower stream is adjusted to vary within a range smaller than the range of variation of the pressure supplied to the primary side. Thus, reduced and regulated pressure is supplied to the primary side of the reducing pressure valve on the side of the lower stream. The air supplied to the primary side of the reducing pressure valve on the side downstream, are further reduced to reduce the pressure valve on the side of the lower thread and then emerges from its secondary side. At this time, the pressure coming out of the secondary side, reducing the th pressure valve on the side downstream, is adjusted to vary within a range smaller than the range of pressure changes emerging from reducing the pressure valve on the side upstream. Thus, the design incorporating serial reducing pressure valves, provides a more stable output pressure as compared with the case of using a single reducing the pressure valve.

For the same reason, the effect of stabilization of certain pressure can be obtained only by adding a reducing pressure valve without providing the second buffer capacity. However, due to the supply of the second buffer tank 22 of the air, which is the object of stabilizing the pressure, through the second reducing pressure valve, the pressure in the flow path located downstream from the buffer tank 22 can be further stabilized.

Using device Options run 2 having the above construction, the size of the device is increased in comparison with the size of the device Option, run 1, but the liquid material may be distributed or issued with higher accuracy.

The separate two-phase gas streams are then merged and the nano- or microparticles are deposited on polymer particles owing to electrostatic interaction between the oppositely charged nano- or microparticles and polymer particles. The nano- or microparticles are fixed on the polymer material owing to the effect of the electromagnetic field on the polymer particles together with particles deposited on their surface. Articles are produced from the modified polymer materials using a standard technique using an extrusion machine and then moulding the articles.

EFFECT: possibility of obtaining the best conditions for charging and dispersing nano- or microparticles, conditions for charging polymer particles, as well as high efficiency of the process of fixing nano- or microparticlees on the surface of polymer particles.
