Description

[Detailed Description of the Invention] [Industrial field of application] The present invention is an IC handler for mounting an IC device on a tester and testing the electrical characteristics of the IC device. The present invention relates to a separation device for an IC device magazine for separating each of them.

[Prior Art] An IC handler stores a large number of IC devices to be tested arranged in a magazine, stores the IC devices one by one, and performs a test measurement by taking out the IC devices one by one. I am sending it to. For this reason, the IC handler has a loader section for supplying the IC device, and a magazine accommodating the IC device is installed in the loader section, and the IC accommodated inside the magazine is inclined by tilting the magazine. The device slides down by its own weight and is transported toward the test section. Here, in order to reduce the frequency of the work of mounting the magazine on the loader section, the loader section is provided with a pair of guide posts each having a guide groove for guiding both ends of the magazine, and a magazine is provided between both guide posts. The magazines are mounted in a stacked state, and the magazines are taken out one by one from the lower part of the guide post.

Therefore, the so-called DI
When a P-type device is used, the magazine 1 shown in FIG. 5 is conventionally used. The magazine 1 is formed with a device storage portion 3 for storing a large number of DIP type IC devices 2 having a plurality of lead portions 2b extending downward on both sides of the substrate portion 2a side by side. Here, the device storage unit 3
In order to store the IC device 2 in a stable state, the bottom surface of the magazine 1 is formed with a convex device mounting portion 4, and the IC device 2 has a substrate portion thereof.
The lower surface of 2a is brought into contact with the upper surface 4a of the guide portion 4, and the left and right lead portions 2b, 2b are housed along the rising walls 4b, 4b. Therefore, the groove portion 5 is formed on the lower surface of the magazine 1.

As shown in FIG. 6, the magazine 1 is stacked by inserting both ends of the magazine 1 into the guide grooves 6a, 6a provided so as to face the left and right magazine posts 6,6. Thus, the IC devices 2 are separated and taken out one by one from below, and the IC device 2 is sent to a position where the IC device 2 is dispensed.

For this purpose, a magazine separating mechanism is provided. As the magazine separating mechanism, a magazine holding means provided with a separating claw 7 composed of a reciprocating rod, a rotating hook and the like provided at the bottom of both magazine posts 6 and a cylinder. It is composed of a magazine transfer means composed of 8a and 8b and a magazine carrier means composed of a carrier base 9. The separation claw 7 is provided at a position at least slightly higher than the height dimension of one magazine 1 of the transport base 9 and is inserted into the groove portion 5 of the lowermost magazine 1 so as to enter the magazine mounting portion. By engaging with the lower surface of 4, it can be held.

The cylinders 8a and 8b are used to transfer the magazine 1 to the transport base 9, and the cylinder 8a is provided at a position where it abuts on the lowermost magazine 1 held by the separation claw 7 and the transport base 9.
It can be reciprocally displaced to a lower position. In addition, the cylinder 8b is 1
It can be reciprocated between a position below the height of the book magazine 1 and a position below the transport surface of the transport base 9.

Further, the transport base 9 can be reciprocated between the position below the magazine post 6 and the position where the means for tilting the magazine 1 is arranged.

Therefore, while the lowermost magazine 1 is held by the separating claw 7, the cylinders 8a and 8b are displaced to the raised position to separate the separating claw 7 from the lowermost magazine 1, so that the magazine 1 is moved to the cylinder 8a. Abut. After that,
By lowering the cylinder 8a and bringing the lowermost magazine 1 into contact with the cylinder 8b, the entire stacked magazines are lowered by one height. Therefore, when the separating claw 7 is operated, the separating claw 7 is engaged with the magazine 1 at the second stage from the bottom stage. Then, when the cylinder 8b is lowered, the lowermost magazine 1 located on the cylinder 8b is separated from the others and placed on the transport base 9.
Therefore, by moving the transport base 9 from the position of the magazine post 6, one magazine 1 can be separated and taken out.

[Problems to be Solved by the Invention] Here, when the magazine 1 is supplied to the IC handler, one side of the device storage unit 3 is opened so that the IC device 2 can be taken out. However, the other side is closed to prevent the IC device 2 from falling off. As described above, a plug is provided in the device storage unit 3 in order to close one end of the device storage unit 3, but the magazine 1 is provided in the guide groove 6a of the magazine post 6. Since the insertion claws are inserted and stacked, and the separation claw 7 is engaged with the magazine 1, the stopper cannot be protruded from the magazine to the outside, and the stopper is inserted in the magazine. It is supposed to be installed.

However, as described above, when the stopper is mounted so as to be embedded in the device housing portion 3 of the magazine, it becomes impossible to attach or detach the stopper.
The direction of the IC device entrance is determined, and the IC device must always be inserted and removed from one side.
Therefore, the IC devices in the magazine must always be used with their directions aligned, and it is necessary to invert and store the IC devices due to the relationship between the pre-process and post-process of this test / inspection process, and after the removal. There is a disadvantage that it causes inconvenience such as the necessity of reversing.

The present invention has been made in view of the above points, and an object of the present invention is to separate a magazine for an IC device from a magazine device without giving direction to the IC device entrance in the magazine. It is to ensure that they can be separated.

[Means for Solving the Problems] In order to achieve the above-mentioned object, the present invention provides a main body in which a rubber plug for closing one side of a magazine enters a device accommodating portion of the magazine and frictionally engages with an inner wall thereof. Part and a rectangular plate-shaped tongue piece that contacts the end face of the magazine and covers the groove of this magazine are connected in series, and a pair of magazine posts with guide grooves for guiding both ends of the magazine are provided. , At a position higher than the height dimension of at least one magazine from the transport surface on the transport base, one guide post is provided with a detachable separation claw on the lower surface of the device mounting portion of the magazine, and The guide post on the side is provided with a pressing pad that can be brought into contact with and separated from the outer surface of the tongue portion of the rubber plug.

[Operation] The rubber plug that closes one side of the magazine has its main body inserted into the device accommodating portion of the magazine, and the tongue piece is continuously connected to this main body. Since it has a flat rectangular plate shape that contacts the end of the magazine, the pressing pad as a mechanism for separating the magazine does not directly contact the magazine, but a wide surface on the tongue part of the rubber stopper. Therefore, the magazine is not brought into contact with the magazine elastically so that the magazine is not removed or deformed. Therefore, the tongue portion of the rubber plug can be extended downward, and thus the extension of the rubber plug can be easily attached and detached. In this way, by attaching and detaching the rubber stoppers, it is possible to insert and remove the IC device from both sides of the magazine, leave the rubber stoppers on both sides, and attach it to the IC handler. If one of the rubber plugs is pulled out when the rack is mounted, the trouble of reversing and storing the IC device in the pre-process and post-process of this test / inspection process is eliminated.

[Embodiment] An embodiment of the present invention will be described below in detail with reference to the drawings.

First, FIG. 1 shows a cross section of the magazine 10. As is clear from the figure, the shape of the magazine itself and the IC device 11 housed in this magazine 10 have the same configurations as those shown in the prior art. Also, one side of the device storage section 12 of this magazine 10 is opened and the other side is closed by a plug. As this plug, as shown in FIG. A rubber plug 13 is used in which a rectangular plate-shaped tongue piece 13b is connected to a main body portion 13a that is inserted inside and has an uneven outer surface. When the rubber stopper 13 is attached to the magazine 10, its main body 13
a enters into the device accommodating portion 12, the protruding portion thereof comes into frictional engagement with the inner wall of the magazine 10, and the tongue piece 13b abuts on the end face of the magazine 10 and the device mounting of the magazine 10 is carried out. It is in a state of protruding toward the groove 10b formed in the lower portion of the placing portion 10a, and therefore, if the tongue piece 13b is pulled by hand, it can be easily detached from the magazine 10.

As shown in FIG. 3, the magazine 10 in which the IC device 11 is housed in the device housing 12 in this way has guide grooves 20a and 21a formed on the magazine posts 20 and 21 at both ends thereof, respectively.
It can be placed in a laminated state by being inserted into the. Although three rows of guide grooves are provided in the figure, the number of rows of the guide grooves is not limited to this, and one row or a desired number of rows can be provided.

A separating mechanism is provided to separate and take out the magazines 10 one by one in each row from below the guide grooves 20a, 21a of the magazine posts 20, 21. The magazine holding means in this separating mechanism is composed of a separating rod 22 provided on the magazine post 20 on one side and a pressing pad 23 provided on the magazine post 21 on the other side. Separation rod
The cylinder 22 can be moved back and forth by a cylinder 24. Further, the pressing pad 23 has a rod 23b connected to a pad portion 23a which can be brought into contact with and separated from the tongue piece 13b of the rubber stopper 13 mounted on the magazine 10 at the tip, and the rod 23b is connected to the cylinder 25
It is designed so that it can be moved back and forth. The pad portion 23a is normally urged by the spring 25a in the protruding direction.

Therefore, when the separating rod 22 and the pressing pad 23 are in the projecting state, the separating rod 22 is placed in the device storage portion of the magazine 10.
The pressing pad 23 abuts on the lower surface of the guide portion 12a of the magazine 12, and the pressing pad 23 abuts on the rubber plug 13 mounted on the magazine 10. It will be held in a state of being pressed against the guide groove 20a. Here, since the rubber plug 13 is a member having a large frictional force and elasticity, when the pressing pad 23 is pressed against the tongue piece 13b, the rubber plug 13 comes into very good elastic contact, causing a slip or the like. Since the magazine 10 can be held in a stable state without being damaged, even with a comparatively weak force, the magazine 10 is not removed and the magazine 10 is not deformed.

Also, a magazine 10 stacked between magazine posts 20 and 21.
At the lower position of the
6 and 27 are provided, and a transportation base 28 as a transportation means of the magazine 10 is also provided. Each of these cylinders 26,2
7 includes receiving plates 26a and 27a that come into contact with the lower surface of the magazine 10,
One of the cylinders 26 has a receiving plate 26a between a position below the conveying surface of the conveying base 28 and a position where the receiving plate 26a abuts the lower surface of the magazine 10 at the holding position engaged with the separating rod 22 and the pressing pad 23. It can be displaced back and forth. The other cylinder 27 has its receiving plate 27a at a position below the carrying surface of the carrying base 28 and below the height of one magazine of the magazine 10 at the holding position described above. It can be moved back and forth between them.

This embodiment is constructed as described above, and its operation will be described below with reference to FIG.

First, as shown in FIG. 4 (a), the magazine 10 is stacked between a large number of magazine posts 20 and 21,
By making the separating rod 22 and the pressing pad 23 project, the lowermost magazine 10 is engaged and held.

Therefore, as shown in FIG. 4 (b), the cylinders 26, 27 are
This causes the receiving plates 26a and 27a to be displaced to the raised positions. As a result, the receiving plate 26a contacts the lower surface of the magazine 10. After that, the cylinders 24 and 25 are operated to displace the separating rod 22 and the pressing pad 23 in the direction shown by the arrow in the figure, thereby separating them from the magazine 10.

Next, as shown in FIG. 4 (c), when the cylinder 26 is contracted, the receiving plate 26a descends to stack the magazines 1
The entire 0 moves down to the position where the lowermost magazine 10 contacts the receiving plate 27a of the cylinder 27 and stops. In this state, operate the cylinders 24 and 25 to
And the pressing pad 23 is projected in the direction shown by the arrow in the figure. As a result, the magazine 10 of the next stage is separated by the separation rod 22.
And the pressing pad 23 holds the clamped state.

Further, when the cylinder 27 is lowered, only the lowermost magazine 10 is separated from the others and mounted on the transport base 28 as shown in FIG. 4 (d). Therefore, by moving the transport base 28 to a predetermined position, one magazine 10 can be taken out separately from the others.

By repeating the above operation, magazine posts 20,2
The magazines 10 stacked between the guide grooves 20a and 21a of 1 can be sequentially separated and taken out one by one.

Thus, as the one-side magazine holding means, the one-side member engages with the separating rod 22 that engages with the convex portion on the lower surface of the magazine 10.
However, since the member on the other side is brought into contact with the rubber stopper 13, it is possible to provide the rubber stopper 13 with a tongue piece 13b that covers the convex portion of the lower surface of the magazine 10. , Put your finger in the groove 10b, and pinch the front and back of this tongue piece 13b with your fingers,
Both ends of the magazine 10 can be opened by a simple operation such as pulling out.

As a result, it is not necessary to give directionality to the insertion / removal of the IC device 11 in / from the magazine 10, and for example, after completion of the work in the step prior to the step of mounting this IC handler, the magazine 10 is stored from either direction, The same shape rubber stopper 13 is attached and stored in a closed state, and when mounted on an IC handler, the rubber attached to the front side in the traveling direction of the IC device 11 housed in the magazine 10 is stored. It suffices to remove the plug 13, and no work such as replacement of the IC device 11 is required.

[Advantage of the Invention] As described above, according to the present invention, as the magazine holding means, the guide post on one side is provided with the detachable claw on the lower surface of the device mounting portion of the magazine and the guide post on the other side. Since a pressing pad is provided on the tongue, and the pressing pad is brought into contact with the tongue portion of the rubber stopper located outside the magazine, the magazine can be held securely even with a relatively weak pressing force, and slippage can be prevented. It can be prevented from being deformed due to strong pressing force acting on the magazine, and the plug that closes one side of the magazine can be attached and removed very easily. It is possible to eliminate the directionality when inserting and removing IC devices in, and to refill or invert the IC devices in relation to the IC device flow direction in the pre-process and post-process. It has various effects such as the necessity of performing it.
