Abstract

PURPOSE:To make IC sticks automatically align and feedable, by installing a device checking an abnormal attitude of each IC stick as well as installing a chuck device which corrects the IC stick to the normal attitude according to a judgment of this check device. CONSTITUTION:After IC sticks 2 inside a hopper 3 drop down on a feed conveyor 4, they further drop down on a moving carrier 9 via a conveying shooter 6, and conveyed up to a check position Pc. At this time, first a stick keeper 12 is made to go down, checking thickness d of each IC stick 2, and that whether any of these IC sticks falls down or not is discriminated. And, when some one falls down, the IC stick 2 is rotated as far as 90 deg. with symmetrical chucks, making it stand upright. Next, a detection pin 15 is pushed up by a solenoid 18 and thereby whether the erected IC stick is normal or upside down or not is checked. And, when the detection pin 15 comes into contact with the IC stick 2, the IC stick 2 is rotated by 180 deg. with upper and lower chucks.

Description

DETAILED DESCRIPTION OF THE INVENTION TECHNICAL FIELD The present invention relates to an automatic IC stick feeding device for an IC autoinserter.

BACKGROUND OF THE INVENTION In general, manufactured ICs are stored in IC sticks to protect the products. When an IC is mounted on a board in the printer 1, high-speed processing is performed using an IC auto-inserter (automatic IC insertion machine). Here, 1-IC sticks have different shapes and lengths depending on the manufacturer, while some IC auto inserters require the use of dedicated IC sticks.

Therefore, ICs are being refilled from stored IC sticks to dedicated IC sticks.

As this IC refilling/supplying means, a specialist refills the IC manually, aligns and stores the dedicated IC sticks with refilled ICs in a magazine while observing their direction, and sets this magazine in an IC auto-inserter. There is a method. There is also a method of refilling using an IC refilling device, but in this case as well, the dedicated IC stick with the IC refilled is processed separately, so the direction of the dedicated IC stick must be checked by a specialist. This allows them to be stored in a magazine in an aligned manner. In any case, the supply means to the I'C auto-inserter involves manual alignment work, resulting in slow processing speed and inefficiency.

the purpose The present invention was made in view of these points.

=2- It is an object of the present invention to provide an automatic IC stick supply device that can automatically align IC sticks input in bulk and supply them in a normal state, thereby improving processing capacity.

composition An embodiment of the present invention will be described based on the drawings.

First, FIGS. 1 and 2 show the shape of an IC stick 2 to be refilled with ICI, and a recess 2a is formed on the bottom surface. The dimensions of each part are a.

b, c, and a#b≠C. Refilling the IC stick 2 with the IC C1 is performed by a refilling device,
It shall be discharged in bulk.

Therefore, the IC for the IC auto-inserter is shown in Figure 3.
The structure of the stick automatic feeding device is schematically shown. first,
A hopper 3 for storing IC sticks 2 in bulk is provided on a conveyor 4. This hover 3 is box-shaped with inclined plates 5 arranged alternately inside, and a vibrator is attached to the side surface to have the function of dropping the IC sticks 2 onto the conveyor 4 one by one. Moreover, the conveyor 3-conveyor 4 is based on a belt with a caterpillar structure, and the I
It has a function of dropping the C sticks 2 one by one into the transport chute 6 (natural fall). A reflective stick passage sensor 7 is provided at the entrance of the transport chute 6. Further, the lower end of the shooter 6 is located above the chip 8 for the IC auto-inserter, and is provided with a movable carrier 9 for receiving the IC stick 2 dropped from the shooter 6. This moving carrier 9 is driven by an air cylinder 10 and moves to the original position WP.

・It reciprocates between check positions Pc.

Here, a check means 11 is provided at the check position Pc, the structure of which is shown in FIG.

First, a stick presser 12 is provided which presses the IC stick 2 carried by the moving carrier 9 to the check position P'e from above and reads and outputs the thickness with a digital gauge. Further, a hole 13 is formed in the table 8 at the check position Pc, and a pin 14 that is guided by the hole 13 and can move up and down is provided. A detection pin 15 that can fit into the recess 3 of the IC stick 2 is provided at one end of the tip 4 of the pin 14 . The lower end of this pin 14 is connected to a solenoid 18 via a lever 16.17. Here, 19 is a fixed fulcrum, and levers 16 and 17
A torsion spring 20 is provided between them. Further, a transmission type sensor 21 is provided for the pin 14 to check its movement. Furthermore, a chuck 22 is provided that can grip the IC stick 2 located at the check position Pc from the left and right or from the top and bottom (hereinafter referred to as the left and right chuck or the top and bottom chuck, but they are the same thing).

In such a configuration, the operation will be explained with reference to the flowchart in FIG. First, by pressing the start button, the conveyor 4 and the vibrator of the hopper 3 start driving, and the ICs loaded in bulk into the hopper 3 are activated.
One stick 2 falls onto the conveyor 4. Then, when the IC stick 2 is detected by the stick passage sensor 7, the conveyor 4 and the vibrator are stopped 5-, and the IC stick 2 falls onto the moving carrier 9 via the conveyor chute 6. When this fall onto the carrier 9 is detected by the sensor, the air cylinder 10
The carrier 9 is driven forward and the IC stick 2 is carried to the check position Pc. So, stick hold down 1
2 is first lowered to check the thickness d.

Here, when looking at the state of the IC stick 2 on the carrier 9, it is in one of the states shown in FIGS. 5(,) to (d). In this embodiment, the state shown in FIG. 3C is the normal posture. Therefore, the abnormal posture shown in FIG. Therefore, the thickness check using the stick holder 12 is performed in the dimensions shown in FIG.
) is used to determine whether the IC stick 2 is fallen down or not. thickness d
If = a, then the state shown in FIG. 5(C) or (d) is reached.

If the IC stick 2 is now lying down as shown in Fig. 5(,) or (b), the left and right chucks 22 move forward relative to the IC stick 2 as shown in Fig. 6(a), and the left and right chucks 22 move forward as shown in Fig. 6(b). The robot is chucked as shown in the figure, rotated 90 degrees as shown in FIG. 3(c), and then released and retreated. With this process, the IC
The stick 2 is in the state shown in FIG. 5(c) or (d).

Then, it is checked whether the IC stick 2 is normal or turned over. Here, since b>a, the stick presser 12 is lowered for the second time and the IC stick 2 is held down, and the detection pin 15 is pushed up by driving the solenoid 18. Now, assuming that the IC stick 2 is in a normal posture, the detection pin 15 can rise due to the recess 2a as shown in FIG. . Then, the detection pin 15 returns, and the upper and lower chucks 2 move forward from both ends of the IC stick 2 in the elongated direction to chuck it. On the other hand, if the IC stick 2 is upside down as shown in FIG. 7(b), the solenoid 18
Although the suction operation is performed, the sensor 21 checks that the detection pin 15 collides with the IC stick 2 and does not rise because it escapes at the torsion spring 20 portion. As a result, it is determined that the detection pin 15 is turned over, and after the detection pin 15 returns, the upper and lower chucks 2
2 moves forward and the IC stick 2 moves forward as shown in the same figure (b).
is chucked and rotated 180° as shown in the figure (c) to bring it into a normal state.

After that, while holding the IC stick 2 with the chuck 22, hold it for 20 mm, move the moving carrier 9 backward, and
Return stick 2. As a result, the IC stick 2 is placed on the table 6 in a normal state. Then, the moving key carrier 9 is reciprocated once to send the IC stick 2 on the table 6 forward, one cycle of processing is completed, and the next IC stick 2 is waited for to fall.

In this embodiment, the state shown in FIG. 5(c) is assumed to be the normal state of the IC stick 2, but depending on the usability, the state shown in FIG.
) may be considered the normal state.

8- Effects As described above, the present invention uses a checking means to check for abnormal postures such as falling or turning over the IC stick, and if the IC stick is in an abnormal posture, it is gripped by a chuck means according to the judgment so that it can be returned to a normal posture. Since the rotation is corrected, the IC sticks inserted in bulk can be automatically corrected to their normal posture, aligned, and fed to the IC auto-inserter, thereby eliminating the need for dedicated personnel and improving processing capacity. It is something that can be done.
