Description

[Detailed Description of the Invention] This invention relates to a component positioning device for sequentially transporting and positioning circuit components such as integrated circuits (ICs) to each processing station.

An IC, which is generally known as an integrated circuit component, has an IC main body 1, as shown in the top view at ``A'' in Figure 1.
and a plurality of connection leads 2 protruding from both sides thereof.

However, in order for an IC configured in this way to become a final completed component, the tips of the connection leads must be made thinner to make it easier to attach to a printed circuit board (not shown), or You have to go through various processing steps, such as straightening the bends in the lead.

Therefore, it is necessary to sequentially transport and position the ICs to each processing station where such processing is to be performed, but it has been difficult to manufacture such a positioning device in the past.

Even if the front edge 3 of the IC main body 1 is selected as the positioning reference, if the dimension S from the edge 3 to the first connection lead is different from the number of connection leads attached to the IC,
As shown in FIG. Dimensions vary not only for ICs with different numbers of leads, but also for ICs with the same number of leads, so correct positioning cannot be expected by simply grasping the connection leads and transporting them. It was due to circumstances.

In other words, there is no suitable reference for positioning, and as a result, an automatic positioning device cannot be realized, and as a result, the processing of IC connection leads is carried out manually, step by step, which is inefficient. there were.

This invention was made based on the conventional technical background as described above, and therefore, the purpose of this invention is to correctly position a component that has multiple connection leads on each side. The purpose of the present invention is to provide a positioning and conveying device that can perform the following tasks.

The main point of the configuration of this invention is that a component equipped with connection leads on both sides is made to straddle the transfer path by means of the leads, and can be moved toward or away from each other while facing each other from both sides. Another feature of the present invention is that the component is positioned by a positioning member consisting of two retaining members each having a tapered pawl that engages between the leads of the component and separates from the lock when the component is moved away.

Next, this invention will be explained in detail with reference to the drawings.

FIG. 2 is an explanatory diagram of the operating principle necessary to explain the operating principle of this invention, and FIG. 3 A is a line A--A in FIG.
It is a sectional view along line A', and the opening in FIG. 3 is a sectional view taken along line A-A' in the opening in FIG.

Please refer to FIGS. 2 and 3.

In FIG. 2A and FIG. 3A, the IC main body 1 straddles the transfer path 4 by its connection lead 2.

There are two engaging members 5a, 5b facing each other on both sides of the IC body 1, and each retaining member has a tapered claw 6a, 6b, respectively.

The retaining members 5a and 5b can move toward each other from both sides of the IC body 1 so that the tapered claws 6a and 6b engage between the leads 2 and 2, or can move away to release the retaining. be.

The openings in FIG. 2 and FIG. 3 show a state in which the engaging members 5 a and 5 b approach each other and the tapered claws 6 a and 6 b are engaged between the leads 2 and 2 of the IC body 1, respectively.

If the engaging members 5a and 5b are simultaneously moved, for example, in the direction of the arrow in this secured state, the IC body 1 can be transported while straddling the transport path 4.

After conveying to the predetermined position, the engaging members 5 a and 5 b
The tapered claws 6a, 6b and the lead 2 are separated from each other.
After disengaging the retaining members 5a and 5b, the retaining members 5a and 5b are moved in the opposite direction and returned to their original positions.

In this way, the IC main body 1 is transported and positioned.

Note that the stopper 7 is
This is a stopper that descends from above and presses the IC body 1 against the transfer path 4 to prevent the IC body 1 from moving inadvertently until the subsequent processing is completed, but it is not shown in FIG.

FIG. 4 is an enlarged view of the state in which the tapered claw 6 of the retaining member is engaged between the leads 2.

Referring to the figure, even if there is a variation in the distance between the leads 2 and 2, the tapered claw 6 moves in the direction of the arrow to absorb the variation, and the apex of the tapered claw 6 becomes the lead. It will be appreciated that they are properly positioned and engaged in the center position of 2 and 2.

Further, the side edge 8 of the engaging member can suppress and prevent the IC body from shaking during transportation.

In other words, even if the IC body swings during transportation, the ends of the leads 2 come into contact with the side edges 8 and are held down.

FIG. 5 is a top view showing an embodiment of this invention, in which the retaining member is in an open state and the mouth is in a closed state.

Refer to Figure 5A. IC body 1 is its connection lead 2
The retaining member 5 is sandwiched between the transfer path 4 which is spanned by the
a and 5b are located.

Since each retaining member has four tapered claws 6a and 6b, it is possible to position four ICs at the same time.

The opening/closing member 9a integrally formed with the retaining member 5a and the opening/closing member 9b integrally constituted with the retaining member 5b move toward each other along the two shafts 10 (this is called a closing operation). It is engaged with the shaft 10 in an appropriate manner so that it can be moved away (this is called an opening operation).

Further, there is a cylinder 11 and a piston 12 that reciprocates within the cylinder 11. The opening/closing member 9b is fixed to one end of the piston 12, and the opening/closing member 9a is fixed to one end of the cylinder 11.

Therefore, when the piston 12 reciprocates within the cylinder 11, the opening/closing member 9b (and the engaging member 5b) fixed to the piston 12 and the opening/closing member 9a (and the retaining member 5a) fixed to the cylinder 11 side are moved. It is designed to open and close, and when opened, the IC body 1 is placed across the transfer path 4, and then the tapered claws 6a and 6b are engaged between the connecting doors 2 and 2. (In addition, the closed state is the fifth
(However, in this figure, the IC main body 1 is not straddled over the transfer path 4, so the taper claws are not engaged between the leads.)

Now, the cylinder 11 is fixed to a movable member 13 via a plate member 17, and the movable member 13 is configured to be movable left and right along a shaft 14.

Also, a piston 16 reciprocating within the second cylinder 15
A moving member 13 is coupled to one end of the movable member 13 via a coupling member 18 .

Therefore, when the piston 16 reciprocates within the cylinder 15,
The moving member 13 coupled to the piston 16 is connected to the shaft 14
It will move left and right along.

It goes without saying that any appropriate well-known technique may be used to drive and control the relative motion between the cylinder and the piston fitted therein.

Since the configuration is as described above, the operation will be explained next.

Since the engaging members 5a and 5b are open in the state shown in FIG. 5A, the IC body 1 is caused to straddle the transfer path 4 at this time.

Next, the first cylinder 11 and the piston 12 fitted therein are moved relative to each other, for example, back and forth, so that the opening/closing member 9a (and the engaging member 5a) coupled to the cylinder 11 and the piston The opening/closing member 9b (and the engaging member 5b) coupled to the shaft 12 is closed along the two shafts 10.

As a result, the tapered claws 6a on the engaging members 5a, 5b
, 6b engage between the connecting leads 2 and 2 from both sides of the IC body 1.

Next, when the second cylinder 15 and the piston 16 move relative to each other, for example, the piston 16 moves forward, the moving member 13 connected to the piston 16 via the connecting member 18
cylinder 11. which moves forward along the shaft 14 and is therefore connected to the moving member 13 via the plate member 17. Piston 12, opening/closing members 9a, 9b, two shafts 10
, the engaging members 5a, 5b, and the IC body 1 with the connecting leads 2 engaged with the tapered claws 6a, 6b all move forward along the transfer path 4, and as a result, the IC body 1 is transported. It is carried out.

Next, when the relative movement of the cylinder 11 and piston 12 is controlled and moved forward, the opening/closing members 9a and 9b are opened, and the retaining members 5a and 5b are also opened, so that the taper claws 6a, 6b and I
C is also disengaged from the connection lead 2.

Therefore, when the relative movement of the cylinder 15 and the piston 16 is controlled and the cylinder 15 and the piston 16 are moved back, all other members except the shaft 14, the transfer path 4, and the IC body 1 that straddles the transfer path 4 move back to their original positions. Return to position.

In this way, one positioning and transporting operation of the IC body 1 is completed.

As explained above, according to this invention, a component equipped with a plurality of connection leads on each side,
It has the advantage that it can be automatically conveyed, and even if there is some variation in lead spacing, it can be absorbed and correctly positioned, and it also has the effect that processing steps for connection leads such as ICs can be carried out more efficiently.
