Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a device for supplying humidified compressed air, and more particularly, to a chip-shaped circuit component supply device (bulk feeder) for extracting and supplying chip-shaped circuit components stored in a bulk in a component container in a row. It relates to a device suitable for supplying compressed air for carrying circuit components.

[0002]

[Prior art]

 The conventional chip-shaped circuit component supply device is a so-called sliding hopper type in which a hopper-shaped component container slides up and down. That is, a sloped surface with a funnel-shaped slope is formed on the bottom surface of the parts container, and the upper end of the parts discharge pipe whose tip is opened obliquely is opened from the through hole opened in the lowest central part of this sloped surface. It has been inserted. In this state, the parts container reciprocates up and down, whereby the parts container slides up and down with respect to the parts discharge pipe, and the upper end of the parts discharge pipe relatively reciprocates up and down in the parts container. As a result, the chip-shaped circuit components in the component container are pushed down and enter the component discharge pipes one by one. In this way, the chip-shaped circuit components a that have entered the component discharge pipes are lined up in a line and sequentially fed downward.

However, in such a conventional chip-shaped circuit component supply device, a power for reciprocating the component container up and down with respect to the component discharge pipe and a mechanism for transmitting the power to the component container are required, The configuration of the device becomes complicated as a whole. Further, the control system of the device is complicated and the operation is troublesome, so that there is a drawback that the device is expensive to manufacture and the operation is complicated.

Therefore, in order to solve this drawback, an air-type chip-shaped circuit component supply device has been developed in which chip-shaped circuit components are aligned and delivered by blowing air into the component container. This air-type chip-shaped circuit component supply device injects compressed air to the lower side of the component container, and while stirring the chip-shaped circuit components with this compressed air, the chip-shaped circuit components are arranged vertically in a line in the component discharge path. It is something to send. The chip-shaped circuit components sent to the component discharge path are escaped one by one to the pipe-shaped component transport path by the escapement, and are transported to a predetermined location through the component transport path.

As the compressed air to be sent to such a chip-shaped circuit component supply device, conventionally used is one used in a factory. The air pressure of the compressed air used in this factory is relatively high at ³ to 8 Kgf / cm ² .

[0006]

[Problems that the device is trying to solve]

The pressure of the compressed air sent to the chip-shaped circuit component supply device is about 0.7 Kgf / cm ^2, which is a relatively low pressure. For this reason, the compressed air with a high atmospheric pressure used in the factory cannot be used as it is, and the atmospheric pressure was lowered through a regulator etc. before being sent to the chip-shaped circuit component supply device.

However, when the atmospheric pressure of the high-pressure compressed air is reduced and sent to the chip-shaped circuit component supply device, the humidity of the air, which is sprayed into the component container of the chip-shaped circuit component supply device and whose pressure is lowered, becomes extremely low. For this reason, the humidity of the entire component container becomes low, and the chip-shaped circuit components are attracted to each other due to static electricity in the component container. For this reason, the chip-shaped circuit components are hardened without being separated from each other, and the chip-shaped circuit components cannot be smoothly discharged from the component container. Moreover, when static electricity is discharged from the chip-shaped circuit component, electricity may flow to the internal electrodes through the external electrodes, which may cause dielectric breakdown between the internal electrodes.

In view of the above-mentioned conventional problems, it is an object of the present invention to provide a compressed air supply device that does not cause static electricity damage due to dry air.

[0009]

[Means for Solving the Problems] That is, in order to achieve the above object, the present invention provides a compressor 16 for pressurizing air and an air compressor of the compressor 16 in a compressed air supply device for pressurizing and sending air. An air conditioning room 12 formed around an inlet 24, an air intake 13 for introducing air into the air conditioning room 12, and a humidifier 14 for humidifying the air in the air conditioning room 12. A compressed air supply device is provided. In addition to the humidifier 14 that humidifies the air in the air conditioning room 12, a dehumidifier 15 that gradually dehumidifies the air in the air conditioning room 12 may be provided.

[0010]

[Action]

In the compressed air supply device, the compressor 16 that pressurizes the air takes in the air from the air conditioning chamber 12, and the air in the air conditioning chamber 12 is humidified by the humidifier 14 in advance. Therefore, when the compressor 16 pressurizes the air from the atmospheric pressure to a relatively low pressure of about 1 Kgf / cm ² , the humidity does not drop extremely. Therefore, when this is sent to the component container or the like of the chip-shaped circuit component supply device, the inside of the component container does not have an extremely low humidity, and the charge of the chip-shaped circuit component or the like can be prevented in advance. In addition to the humidifier 14 for humidifying the air in the air-conditioning room 12, when the dehumidifier 15 for gradually humidifying the air in the air-conditioning room 12 is provided, when dew condensation occurs due to excessive humidification, etc. Moreover, it is possible to quickly dehumidify excess humidity in the air conditioning room 12 and maintain the air conditioning room 12 at normal humidity.

【Example】

Next, an embodiment of the present invention will be specifically described with reference to FIG. FIG. 1 is a schematic view of a compressed air supply device according to an embodiment of the present invention. As shown in the figure, the housing 11 is divided into three sections, and a compressor 16 that pressurizes air from atmospheric pressure to a relatively low pressure of about 1 Kgf / cm ² is installed in one section. The compressed air pressurized by the compressor 16 is sent through the compressed air supply pipe 21 to, for example, a component container of a chip-shaped circuit component supply device described later.

The other compartment of the housing 11 is an air conditioning room 12, which is provided with an air intake 13 for taking in air from the outside of the housing 11, and the compressor 16 The air inlet 24 is inserted. Therefore, the air enters the air conditioning chamber 12 from the outside of the housing 11 through the air intake 13 as shown by the arrow to the right in FIG. 1, is introduced into the compressor 16 from the air conditioning chamber 12, is pressurized, and is compressed air. It is sent to a predetermined position through the supply pipe 21. A sensor head 17 of a humidity sensor 18 is introduced into the air conditioning room 12 so that the humidity inside the room 12 can be measured.

A humidifier 14 and a dehumidifier 15 are installed in another section of the housing. The humidifier 14 vaporizes the water sent from the water supply unit 22 side through the valve 23, sends the water to the air conditioning room 12, and humidifies the air conditioning room 12. The dehumidifier 15 removes moisture from the air in the air-conditioning room 15 and dehumidifies it to dry the air. The operations of the humidifier 14 and the dehumidifier 15 are controlled by the controller 19. In the controller 19, the value of the humidity (relative humidity) in the air-conditioned room 12 measured by the humidity sensor 18 is measured. Feedback control is performed. That is, when the humidity value measured by the humidity sensor 18 is lower than a predetermined set value, the humidifier 14 operates to humidify the air in the air conditioning room 12. On the other hand, when the humidity value measured by the humidity sensor 18 is higher than a predetermined set value, the dehumidifier 15 operates to dehumidify the air in the air conditioning room 12. As a result, the humidity of the air in the air-conditioning room 12 is maintained at a value substantially equal to the set value.

Further, the humidity of the air-conditioned room 12 measured by the humidity sensor 18 is also input to the drive controller 20 of the compressor 16 to operate the compressor 16 during a trouble such as an abnormal decrease or abnormal increase in humidity. To stop. As described above, in the compressor 16, the air is introduced from the air conditioning chamber 12, and the air is pressurized and sent to the predetermined position through the compressed air supply pipe 21, so that the air conditioning chamber 12 is maintained at an appropriate humidity. By doing so, compressed air having an appropriate humidity can be sent from the compressor 16. In the above embodiment, the compressor 16, the air conditioning chamber 12, the humidifier 14, and the dehumidifier 15 are integrated by the housing 11, but such a layout can be changed as appropriate.

FIGS. 2 and 3 show a chip-shaped circuit component supply device for sending compressed air from the compressed air supply device according to the above embodiment. In this chip-shaped circuit component supply device, a partition 42 is provided in the component container 1, a component discharge chamber 6 is formed below the partition 42, and the chip-shaped circuit components a, a ... Are accommodated thereon. Then, the chip-shaped circuit components a, a ... Enter the component discharge chamber 6 from the part of the partition 42 which is opened. Compressed air is injected into the component discharge chamber 6 through the air supply pipe 4 connected to the compressed air supply pipe 21 of the compressor 16 via a regulator or the like. Then, due to the pressure of this air, the pressure inside the component discharge chamber 6 becomes higher than the other parts of the component container 1. Therefore, the chip-shaped circuit component a outside the partition 42 is prevented from being pushed by this atmospheric pressure and entering the component discharge chamber 6 from the component discharge port 7 at a time. Further, since the injected air circulates in the component discharge chamber 6, the chip-shaped circuit components a, a ... Inside the component discharge chamber 6 are carried by this air and disturbed in the component discharge chamber 6. It circulates. In this way, while the chip-shaped circuit component a circulates in the component discharge chamber 6, a part thereof reaches the upper end of the component discharge path 48. The air sent from the air supply pipe 4 to the component container 1 is mainly discharged through the component discharge passage 48 from the component discharge chamber 6, so that the chip-shaped circuit component a enters the component discharge passage 48 by this air flow. It goes in, and from there it is sent vertically in one line.

The chip-shaped circuit part a that has entered the part discharge path 48 enters the part-accommodating hole 64 of the slider 54, which can accommodate only one chip-shaped circuit part a, and the slider 54 moves left and right in FIG. Due to the movement, the two pipe-shaped component transfer paths 10, 10 are alternately released one by one. Then, it is conveyed to a predetermined place through the component conveying path 10. Since the compressed air whose humidity has been adjusted is sent from the compressed air supply device to the component container 1 of this chip-shaped circuit component supply device, the chip-shaped circuit components a, a ... Hard to be charged.

[0017]

[Effect of device]

 As described above, according to the present invention, the air in the air conditioning chamber 12 that has been humidified in advance by the humidifier 14 is pressurized by the compressor 16 and supplied, so that it is possible to prevent an extreme decrease in humidity on the supply destination side. . Therefore, when this is sent to a component container or the like of the chip-shaped circuit component supply device, the inside of the component container does not have an extremely low humidity, and the charge of the chip-shaped circuit component or the like can be prevented in advance. Further, when the dehumidifier 15 that dehumidifies the air in the air-conditioning room 12 is provided, when the humidity in the air-conditioning room 12 becomes particularly high, the excessive humidity is quickly dehumidified to obtain the normal humidity. Moreover, it is possible to maintain the air conditioning room 12. For this reason, it is possible to quickly respond to changes in humidity due to disturbances and the like, and it is possible to reliably maintain appropriate humidity.
