Abstract

PURPOSE:To improve the efficiency of a conductive pin inserting work and to contrive prevention of damage and deformation of the conductive pin by a method wherein an intermittent air stream, to be used for automatic insertion of the conductive pin into the pin inserting hole of each pallet, is formed positively and forcedly using a depressing device and a high pressure gas supplying device. CONSTITUTION:Each pallet 60 is conveyed succesively while vibrations are being given. As each Pin-inserting hole 63 is positioned at the lower part of an internal conveying path 20 and it is brought into the state wherein it is communicated to the air tight box 10 maintained in a depressed state, air is allowed to flow on the lower side of the internal conveying path 20 through the inserting hole 63, each conductive pin 70 is sucked into the inserting hole 63 following said air stream, and the pin is automatically inserted one by one. At this point, by the intermittent feeding of high pressure gas by a high pressure gas supplying device, the conductive pin 70 only, which has not been inserted in the normal state, jumps out from the pallet 60 by the vibration of a vibrator 13, and the next normal inserting operation is performed.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a pin insertion device used when manufacturing a board for mounting electronic components called a so-called pin grid array having a large number of conductor bins. In particular, the present invention relates to a pin insertion device for dynamically inserting conductor pins into pin insertion holes formed in a pallet while sequentially and continuously conveying a pallet corresponding to an electronic component mounting board.

(Prior Art) In an electronic component mounting board called a pin grid array having a large number of conductor pins, a conductive circuit formed on the board side and a board on which the electronic component mounting board is mounted (usually In order to ensure continuity with the motherboard, multiple conductor pins are attached to this type of electronic component board by inserting or fixing them, and these conductor pins connect the electronic component mounting board to the motherboard. This is to establish electrical continuity with the (Refer to Figure 8) In recent years, the electronic components mounted on such boards are becoming smaller and smaller, and there is a strong desire to reduce the overall size after mounting. For this reason, the shape of the conductor pins themselves used in boards for mounting electronic components has become smaller and smaller in recent years. Moreover, even if the conductor bottle is small, it needs to be securely attached to the electronic component mounting board, so its shape is as shown in Figures 6 and 7.
S! It's becoming an erotic thing. The actual size of the conductor bin shown in these figures is 0.5 mm in diameter at its base.
The degree and length are e! It is made of about 5 m of Ir and has a complicated shape with a flange for reliable positioning and support to the substrate. For example, about 20 to 50 conductor bottles of such a small and complicated shape must be attached to a 20 mm square board.

In order to attach about 20 to 50 such small and complex-shaped conductor bottles to a small board, these conductor bottles must be tightened and arranged in a predetermined state using a special barre-soto, etc. In the past, most of this preparation was done manually. However, manually preparing a large number of small conductor bins in a predetermined arrangement is not only very inefficient, but also causes the conductor bins arranged in a predetermined state to accidentally fly out of the pallet during moving operations. Since there are cases where the parts are bent or bent, various studies have been conducted on whether this can be done automatically using a mechanical T-stage.

As a means of automatically arranging such conductor bins,
For example, there is an automatic pin insertion method as disclosed in Japanese Patent Publication No. 53-9714. That is, the method includes the steps of "introducing an elongate object onto a carrier having a plurality of apertures, and vibrating the phase body to disturb the object and facilitate its introduction into the apertures in the support. -h
A pressure difference is created between the 4th part and the lower part of the recording hole, and gas is introduced into the upper part of the opening to cause the object to be sucked into the opening. and periodically reducing the pressure difference to reduce the flow of gas to the top of the bipedal apertures and cooperate with the vibration of the carrier to release the cluttered objects. Although this method can achieve a certain degree of inserting the conductor bottle into the desired location, ■the properties of the gas have not been sufficiently studied; In the equipment to which this method is applied, the speed (efficiency) of inserting conductor bins, the removal of conductor bins that do not fit into the pallet in the required state, and the compactness of cracked bodies have not been perfected.

■The shape and properties of the above-mentioned objects (hereinafter referred to as conductor pins) are not taken into consideration, and it is thought that the conductor bins cannot be handled optimally.

1 like that? ! I still have one problem.

In other words, since gas is a fluid, it takes a certain amount of time to reach a steady state of constant pressure unless some other force is applied. If we apply this to a device that adopts the insertion method described in -12 above, we can see that it takes a considerable amount of time to recover from a depressurized state using atmospheric pressure, so this decompression time can be reduced. If you try to do so, you will have to use a fairly powerful decompression device. Also, even when creating a predetermined decompression state using a fairly powerful decompression device,
It takes time for the pressure to reach a steady state. Moreover, if it is attempted to repeatedly create the above-mentioned reduced pressure state and atmosphere open state in a short period of time, it is natural that certain limits will arise depending on the properties of the gas used. That is,
There are limits to the insertion and effectiveness of the conductor pins.

Further, as described above, the conductor pin is very small and has a complicated shape, so it is easily deformed. Therefore, handling of such conductor pins requires considerable care so as not to deform the conductor pins. Deformed conductor pins are placed on a carrier (pallet)
Not only will it not be possible to insert it into the hole, but even if it can be fixed to the board, the position will not match and the board itself will be considered a defective product.

Examining how the above-mentioned conventional technology handles conductor pins having such properties, it is found that in the 23rd line of the right column on page 5 of the above-mentioned Japanese Patent Publication No. 53-9714, [
The excess object removal device (190) is energized so that excess objects (conductor pins) are pushed toward the chute (99) as the frame (192) moves toward the right in FIG. The object removal frame (192) is held at the rightmost position where it does not interfere with the descent of the mask (202). ” There is a statement to that effect. What can be understood from this description is that in order to use the excess conductor pins again, the object removal frame (192) pushes the excess conductor pins to a predetermined position and collects them again. When the conductor pin is pushed away by (192), the force applied at that time deforms the conductor pin and makes it more likely to be damaged. moreover,
Conductor pins used for electronic component mounting boards usually have 1.
If the conductor pin has been subjected to surface treatment (for example, solder plating) and is subjected to long vibrations from a vibrating device, etc.,
Although it is easily scratched and oxidized when exposed to air, the automatic pin insertion method shown in the above-mentioned Japanese Patent Publication No. 53-9714 has specific features from this point of view. There are no tricks at all.

The inventors of the present invention have conducted extensive research to solve the problems of the above-mentioned conventional technologies, and as a result, the inventors of the present invention have more actively created the pressure difference for inserting the conductor pin into the pallet. In order to prevent conductor pins from being damaged, supplying conductor pins should be consumed in the order in which they were supplied, rather than collecting and reusing excess conductor pins. The present invention was completed based on the new findings that it is advisable to do the following.

(Problems to be Solved by the Invention) The invention has been made due to the above-mentioned circumstances, and the problem to be solved is the poor efficiency of the conductor pin insertion work in the conventional pin insertion device. This is due to damage or deformation of the conductor pin itself.

Not only can the pin insertion work be performed automatically, but also the pressure change for inserting the conductor pin can be actively created to perform the conductor pin insertion work. ■By achieving this, the entire device can be configured compactly.@For continuous and faster pallet feeding, it is possible to continuously insert conductor pins into the pallet. (1) To provide a pin insertion device capable of consuming conductor pins in the order in which they are supplied so as not to damage or deform the conductor pins.

That is, this bottle insertion bag Eff (100) is designed to sequentially transport a plurality of pallets (60) through the internal transport path (20)-H, which is vibrated together with the airtight box (10) by the vibrating bag 71 (+3). Then, the conductor bottles (70) are automatically inserted into the bottle insertion holes (63) formed in this pallet (60).

Furthermore, by providing the supply position of the conductor bin (70), that is, the installation position of the conductor bin supply device (5Q) on the front end side of the internal conveyance path (20), the moving direction of the conductor bin (70) can be adjusted to each pallet (60). The conductor pins (70) are inserted into the bin insertion holes (63) of each pallet (60) in the order in which they are supplied so that the conductor pins (70) are opposite to the conveyance direction with respect to the internal conveyance path (20).
It is configured to be inserted and consumed sequentially within the .

In addition, the internal conveyance path (20
) The inside of the airtight box (10) located on the side of the airtight box (10) is maintained in a reduced pressure state by a suction device (40) connected to this airtight box (10).

Furthermore, in this pin insertion device (100), high pressure gas is supplied to the airtight box (10) at a location located below the internal conveyance path (20) provided in the airtight box (10). High-pressure gas supply device that supplies intermittently (2

Accordingly, the reduced pressure IE by the suction device (40) in the airtight box (10) is actively and intermittently released. That is, the release of this reduced pressure state is performed by the high pressure gas supply device (2110) in step 111! This is done by intermittent forced supply of gas; for example, by opening a part that is under reduced pressure to the atmosphere, the reduced pressure fE
The cancellation can be completed in an extremely short time compared to the method of canceling E. This is done not by the natural physical flow properties of the gas, but by the forced supply of gas by the high pressure gas supply device (200).

Under these conditions, each pallet (60) is sequentially conveyed while being vibrated, and each pin insertion hole (63) formed in the pallet (60) is inserted into an airtight box located below the internal conveyance path (20). (10), air flows to the lower side of the internal conveyance path (20) through each of these pin insertion holes (6). According to this air flow, each conductor pin (70) is attracted into the pin insertion hole (63), and thereby one conductor bottle (70) is automatically inserted into each pin insertion hole (63). It is.

Here, by intermittently supplying high pressure gas by the high pressure gas supply device m (200), only the conductor bottle (70) that was not inserted in the normal state is vibrated by the vibration device (13) and the pallet (60) is ) made to jump out 1

As a result, in each of the pellets (60) that moved forward and reached the pallet transport path (80B), one conductor bottle (70) was inserted into each pin insertion hole (63). The state yE is such that no surplus conductor bin (70) is located on the pallet (60).

200) and a conductor bin supply bag +i! that supplies a large number of conductor pins (70) onto the pallet (60) conveyed through the internal conveyance path (20)-L! ? (50). Note that in the pin insertion device (10(1)) in this embodiment, there is a brush (31) placed above the airtight box (10) and moved by the brush swinging device (30).
It is equipped with

As shown in Fig. 1, the airtight box (lO) is supported in a vibrating manner by a base frame (II) J: arranged at its lower part, and the airtight box (lO) is Vibration is applied by a vibrating device (13) provided in the. In addition, a plurality of suction ports (12) are formed at the bottom of this airtight box (10) as shown in FIG. 1, and each of these suction ports (12) is connected to a decompression device (40). It is.

Furthermore, a conductor pin supply device (50) for supplying a large number of conductor pins (70) onto the airtight box (10) is arranged on the L side of the airtight box (10).

Further, before and after this airtight box (10), a pallet transport path (80B) and (80 8) are located respectively. In this airtight box (10), an internal conveyance path (20) is formed so as to be continuous with the pallet conveyance paths (8013) and (8[IA) located in the front and rear. That is, for this internal conveyance path (20), there is a rear pallet conveyance path (80).
The conductor pin (70) or the pallet (60) that has not been inserted yet is sent from A), and the conductor pin (70) is sent from A).
) inserted pallet (60) or internal conveyance path (20)
The pallet is transported onto the pallet transport path (80B) from the front.

The upper surface of the internal conveyance path (20) is formed to be smooth so that each pallet (60) to be described later can slide thereon, and a plurality of openings are provided at the 'i' portion of the internal conveyance path (20). (21)
is formed. As a result, this internal conveyance path (20)
When a large number of pallets (60) are transported on top of
Inside the space below this internal conveyance path (20) are openings (21).
Through this, it communicates with the two. Also, an airtight box (10) supporting this internal conveyance path (20)
A plurality of rollers (23) are provided on the upper side, and a belt (22) is hooked to each of these rollers (23).

Each of these belts (22) is arranged so as to come into contact with the lower surface thereof or the upper surface of the side part of a pallet (60), which will be described later. Each pallet (60) is sequentially and intermittently fed by an air cylinder (8) shown in FIG. 3), and the belt (22) is driven in a driven manner. The belt (22) thus configured presses each pallet (60) against the internal conveyance path (20) and the airtight box (0), thereby making the vibration of the vibration device (13) more efficient. It is communicated well.

Further, the internal conveyance path (20) in this embodiment is inclined in the - direction toward the rear end side in the conveyance direction of the pallet (60). By providing such a so-called reverse inclination and appropriately setting the strength and direction of the vibration of the vibrating device (13), each conductor pin (70) does not rise on the upper surface of each pallet (60) but moves toward the rear end. It is possible to move to That is, the pin insertion device (1

The surface of the internal conveyance path (20) is descending like two legs in the direction of conveyance (in the direction of the arrow in FIG. 1). The reason why the upper surface of the internal conveyance path (20) is lowered toward the conveyance direction is because the conductor pin (7
0) has its center at a certain part of its flange, and is positioned relative to each pallet (60) in the state shown in FIG. 9. That is, each conductor pin (70) is directionally moved by vibration, and the pallet (60)
In order to facilitate insertion into the pin insertion hole (63) of the pin insertion hole (63), the following structure was adopted.

Furthermore, in the pin insertion device (100) in this embodiment, the conductor pin supply bag 2Il (50) or the internal conveyance path (
20) on the front end side (the side where the pallet (60) is being carried out). As a result, each conductor pin (70) supplied onto the internal conveyance path (20) is controlled by appropriately setting the strength and direction of vibration of the vibrating device (13), and by moving the internal conveyance path (20) onto the pallet [60 ] is formed so as to be inclined in the direction f toward the front end in the transport direction, and the surplus gradually moves toward the rear end of the internal transport path (20).

The suction bag 21 (4G) has a suction port (I2) formed in the airtight box (10) located below the internal conveyance path (20).

Furthermore, the high pressure gas supply device (200) has an internal conveyance path (
20) Airtight box located below Cl0)ffWI
This high-pressure gas supply device (200) is connected to the internal conveyance path (20), contrary to the suction device (40) in L.
) High pressure gas is intermittently supplied to the tight box Cl0)H located below the box Cl0)H. That is, this high-pressure gas supply wave H (zoo) forcibly and intermittently supplies high-pressure gas to the airtight box (10) located below the internal conveyance path (20) that is maintained in a predetermined reduced pressure state. By doing so, the reduced pressure state in the airtight box (1G) is temporarily and forcibly released.

In addition, in the case of this embodiment, the high-pressure gas supply bag m (
This is done by setting the activation and stop intervals of ZOO) to 0.2 seconds each. As described above, since this high-pressure gas supply device (200) repeatedly operates and stops within a short period of time, it is necessary to insert the conductor pin (70) into each pallet (60) (high-pressure gas supply wave 71 (200) )
(when the high-pressure gas supply wave 7i (200) is activated) and conductor pins (70) that are not inserted into each pallet (60) in the normal state (when the high-pressure gas supply wave 7i (200) is activated) must be carried out repeatedly and within a short time. Gataki.

This allows each conductor pin (70) to be inserted into the pallet (60) with high efficiency. In this way, if the insertion efficiency of the conductor pin (70) is increased by the high-pressure gas supply wave; i (200), the airtight box (I0
) Even if conveyance is carried out over a short distance within pallets (50
As a result, the length of the airtight box (10) and the internal conveyance path (20), as well as the length of the pin insertion device (
+00) The overall thigh length can be shortened.

In other words, this high pressure gas supply wave m (200) is.

The depressurized state in the airtight box (10) is not released by the natural flow of gas as in the conventional open-to-atmosphere type, but is actively and forcibly released, and the present invention The automatic manufacturing apparatus shown in FIG. 3 in which the bottle insertion device (100) and the pin insertion device 21 (100) are installed can be configured compactly.

Of course, this high-pressure gas supply device (200) is preferably set in a direction that does not cause energy loss of the discharged high-pressure gas (for example, a direction parallel to the direction of the suction port (12) as shown in FIG. 1). The connection point is not limited to this, but the internal conveyance path (20)
If it is the part of the airtight box (10) located below, the setting or rotation is appropriate.

) can be provided with a simple configuration, which allows the bottle insertion device fi (100) to be inserted reliably and automatically within a short period of time.

That is, in this pin insertion device 7!1 (100), an intermittent gas flow is provided to automatically slide and insert the conductor pin (70) into the bottle insertion hole (63) of each pallet (60). The pressure reducing device (40) and the high pressure gas supply bag 21 (200
), so that they were actively and forcibly made.
Due to the vibration given by the vibration device (13), the conductor pins (70) inserted into each bottle insertion hole (63) in an irregular manner are popped out of each pallet (60) within a short time, and a new one is inserted. This means that the conductor pin (70) can be inserted. In addition, as described above, the conductor pin (70) can be inserted and
Since the removal operation can be performed within a short time, each pallet (50) can be fed continuously and at high speed.

As a result, the conductor pin (70) can be inserted into the pin insertion hole (53) within a short section.
It is also possible to make the pin insertion device (100) compact and small.

Furthermore, the conductor pins (7
0) is usually subjected to a surface treatment (e.g. solder, ν-ki), and the conductor pin (70) is easily scratched when exposed to long vibrations from a vibrating device, etc., and is also exposed to the air. However, according to the bottle insertion device (ioo) of the present invention, the conductor pins (70) are configured to be consumed within a short time in the order in which they are supplied, as described above. Therefore, while being careful not to cause any scratches or oxidation problems on this conductor pin (70), insert it into the pin insertion hole (63) of the pallet (50).
It can be inserted reliably and automatically within a short period of time.

In addition, in this bottle insertion device m (100), since the decompression device (40) is always operated in a constant state, the depressurization state is determined by which opening (21) of the internal conveyance path (20).
The same goes for . Therefore, inside F! 6 conveyance paths (20
) itself is long and the regent's palette (60) is lined up,
Alternatively, even if the conveyance speed of each pallet (60) is increased, the required vacuum width at each opening (21) of the internal conveyance path (20) will not change at all, and the four-body pin (70) relative to the pallet (60) will not change at all. It is possible to provide a pin insertion device 100) with a simple configuration that allows efficient insertion and is effective even when it is desired to speed up the insertion operation.

In addition, in this bottle insertion device (+00), the internal conveyance path (20) is divided by brushes (31), and the conductor pin (70) is prevented from moving into other divisions in this divided portion. In addition, if necessary, remove the brush (
31) is opened, the conductor pins (70) supplied to the front end of the internal conveyance path (20) are not consumed little by little in each section, but move sequentially toward the rear end. As a result, on the pallet (60) located on the rear end side, the conductor pins (70) that have been fed on the pallets (50) on the front end side are supplied to the respective pin insertion holes ( 63).

In other words, the conductor pin (70) once supplied into the bottle insertion device 21 (100) by the conductor pin supply device 22 (50) is completely consumed in the end, and the conductor pin (
70) is not exposed to a condition that could cause damage or deformation. Therefore, as described above, this bottle insertion device (100)
If configured, each conductor pin (70) can be inserted into each pallet (60) in a good quality state, and the pallet (60) can be inserted reliably without damaging or deforming the conductor pin (70). ).
