Abstract

PURPOSE:To improve workability and efficiency by lifting up a magazine holding member and inclining a magazine so that an IC send-in part side is low, in an IC feeding mechanism from an IC magazine to a large handler. CONSTITUTION:A magazine 5 is held by a holding arm 2 and is lifted up to a position at which the longitudinal direction of the magazine 5 is opposite to an IC send-in part 4. At this time, the send-in end part side of the holding arm 2 is brought into contact with a stopper 8 and locked. Accordingly, as the holding arm 2 is further lifted up by a defined amount, only the opposite side to the send-in end part of the holding arm 2 is lifted up, to incline the magazine 5 with the send-in end part side low. Thereby, the IC in the magazine 5 falls naturally being moved to the guide rail 4a. By this structure, workability and efficiency can be improved.

Description

[Detailed Description of the Invention] [Field of Application in Industry-1-] The present invention relates to an IC magazine supply mechanism, and in particular, to a large IC handler, it is possible to supply built-in ICs arranged inside an IC magazine (hereinafter simply referred to as a magazine) to a large IC handler. This invention relates to an improvement in an IC magazine supply mechanism suitable for continuous supply.

[Prior Art] Generally, in the workplace of an IC manufacturer, an IC chip is sealed in a package, and after the window outline is arranged, the IC is stored and handled in a magazine. and through the magazine I
The IC is handed over to a C handler, IC inspection device, etc.

In addition, if the connecting bins are on both sides, I) IPI ~ ri, if the ICs are arranged and stored across the straddle-shaped runway in the magazine in such handling, automatic inspection of ■C, etc. It becomes very easy to supply the IC to the controller and take it out from the IC handler.

Conventionally, magazines for this kind of handling have been supplied by taking out the magazines one by one from the bottom of a stacker in which a large number of magazines are stacked vertically, and placing the magazines in the IC.
The information is supplied to a handler or the like. In this case, the stacker is provided with means at its lower part for taking out and lowering the magazines one by one.

By the way, as the degree of integration of ICs themselves improves and they become multifunctional, the IC package itself becomes larger, and along with the increase in its usage, the number of product inspections also increases, making it difficult to efficiently test a wide variety of products. It has become necessary to do so. As a result, the IC handler itself tends to become larger.

A large IC handler is generally tall, and its IC feeding section (IC receiving section "1") must be located at a high position.

[Problems to be solved] When the IC feeding section is placed at a high position, the position of the stacker, etc. must be raised accordingly. In this case, the workability of setting the magazine in the stacker becomes poor, and a situation that conflicts with efficient inspection processing occurs.

It is also conceivable to supply with a single lever, but this has the drawback of complicating the mechanism.

[Purpose of the Invention] This invention has been made in view of the above-mentioned problems, and in addition to solving the above-mentioned problems, it has good workability and efficiently supplies the magazine to the IC feeding section. An object of the present invention is to provide an IC magazine supply mechanism that can provide an IC magazine.

[Means for Solving the Problems] The means in the present invention for achieving the above object include a movement preventing means provided corresponding to the IC feeding section of the IC handler, and a movement preventing means for moving the IC magazine from a horizontal position. It is equipped with a magazine gripping mechanism that grips the magazine so as to be rotatable in the t direction, and a moving mechanism that moves this gripping mechanism up and down.
Move the IC magazine to the feeding section, position it in a plane where the longitudinal direction of the IC magazine is almost perpendicular to the IC feeding section, and engage the end of the IC magazine or the gripping mechanism with the movement blocking means to remove the IC.
The end of the magazine located on the IC feeding section side is prevented from moving upward, and the IC magazine is raised a predetermined distance to tilt the IC magazine, and the inserted IC is fed into the IC. The project will be sent to the department.

[Function] With this configuration, the IC feeding section of the IC handler and the position of the stacker can be separated at the height position, and the height of the stacker can be freely set. Moreover, since the movement limiter is provided, the magazine can be supplied to the IC handler side with one stroke of upward movement, allowing efficient inspection processing. As a result, even if the IC feeding section of a large IC handler is located at a high position, the stacker does not need to be placed high, and the height of the stacker is not limited, resulting in improved workability. It can be placed in any position.

[Example 1] Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a front view of an IC magazine supplying device according to an embodiment of the present invention, and FIG.
FIG. 3 is a side view seen from the feeding section side, and FIG. 4 is an explanatory diagram of the moving mechanism that moves the gripping arm up and down.
bL (c) is an explanatory diagram of the operation of supplying magazines from the stacker, and FIG. 5 is an explanatory diagram of another vertical movement mechanism corresponding to FIG. 3.

1 is a base (fixed part) on the side of the IC magazine feeder 10, and 2 is a gripping arm. This gripping arm 2 moves downward using the support 3 installed on the base 1''2 as a guide, and rotates from the horizontal position toward the - direction at the position of the IC feeding section 4 of the IC handler. . The vertical movement mechanism is not shown in FIG. 1, but as shown in FIG. 3(b), it is performed here by a belt movement mechanism.

Reference numeral 6 denotes an IC protrusion prevention plate fixed to the base 1, which faces the open end of the magazine 5.
The built-in IC while grasping and moving upward
β11 stops it from popping out.

The tip side thereof is located below the feeding side tip of the preheat chute 4a provided in the IC feeding section 4 on the IC handler side.

In addition, the sensor bracket 7 (see Fig. 2, #4) is attached to the IC protrusion prevention plate 6 with a screw 7a (see Fig. 2).
The sensor bracket 7 is provided with an opening 7b at its upper portion for receiving the leading end of the magazine 5. Then, the IC feeding section 4 is inserted into this opening 7b.
It is positioned in Note that the sensor bracket 7 is provided with an optical sensor (its light emitting section 7c and light receiving section 7d) for detecting the IC being sent out.

On the other hand, in the IC feeding section 4 of the IC handler, the feeding side tip of the preheat shoe 4a is located. And I.C.
The gripping arm 2 of the magazine supply mechanism 10 rises and is positioned at a predetermined distance 1ill on the extension line of the tip of the feeding portion of the preheat shoe 4a.

This preheat chute 4a is fixed inside the IC handler at a predetermined angle by a support member (not shown), and the pop-out prevention plate 6 is located at the tip of the inlet side of the preheat chute 4a, thereby creating an IC magazine supply mechanism. IO is positioned so as to face the IC feeding section 4.

In such a configuration, the magazine 5 is moved to the IC feeding section of the IC handler so that the longitudinal direction of the IC magazine is aligned with the IC.
Position it in a plane that is approximately perpendicular to the feeding section.

Now, the magazine 5 is sent out from the stacker 11 (see Fig. 4), one end of which is located on the IC feeding section 4 side is held by the gripping arm 2, and the magazine 5 is lifted up -L using the support 3 as a guide. , one end of the gripping arm 2 on the feeding end side is I
The IC is locked by a stopper 8 provided near the C feeding section 4 (or the IC is locked at the feeding end position of the guide rail 4a).
One end of the magazine 5 on the feeding section 4 side is directly locked by the stopper 8), and its upward movement is stopped. Then, the gripping arm 2 further rises by a certain amount. As a result, the gripping arm 2 is raised and rotated, and the end of the magazine 5 far from the IC feeding section 4 is rotated and tilted to an angle corresponding to the guide rail 4a.

As a result of the above, the magazine 5 is coupled to the guide rail 4a, and the inserted IC is allowed to fall naturally from the magazine 5 to the guide rail 4a and is supplied. Note that the magazine 5 and the guide rail 4a are such that the straddle-shaped runway in the magazine 5 and the guide rail 4a are linearly arranged and coupled.

By the way, as shown in FIG. 3, the gripping arm 2 is moved up and down by driving the vertical movement mechanism 9.
When moving toward the position of the C feeding section 4 and lowering it, as shown in Fig. 4(b)
The receiver stops at the position where the magazine 5 is taken as shown in the figure. Here, the gripping arm 2 is supported so as to be rotatable upward from a horizontal position relative to a sleeve 2a that fits into the support column 3.

Note that 9a is a drive pulley coupled to the drive motor of the vertical movement mechanism 9, and 9b is a driven pulley located on the opposite side. A stopper 8 positioned at a position corresponding to the IC feeding section 4 is fixed to the upper part of the frame 90 of the upper moving mechanism 9 with a screw.

This stopper 8 locks one end of the gripping arm 2 on the feeding end side (or the end of the magazine 5 on the ICC feeding side side), and locks the gripping arm when it is raised to the IC feeding portion 4 of the IC handler. 2 (or one end of the ICC feeding section side end of the magazine 5 is moved to -), and the gripping arm 2 is further raised by -L, thereby rotating the gripping arm 2.

As a result, the magazine 5 is 5 a v5 as seen in FIG.
b, 5c, and 5d, and joins the guide rail 4a at its straddle-shaped runway.

Now, here, the magazine 5 consists of one stacker 11a, llb arranged in parallel as shown in FIG. 4(a).
, llc, and these stackers lla, llb, 11c have a plurality of magazines 5.
are piled up. Then, by the action of a claw (not shown) provided at the bottom thereof, the magazines 5 fall one by one into the groove of the lateral movement mechanism 12, starting from the stacker lla at the back, as shown in FIG. 4(a).

Next, as shown in FIG. 4(b), the magazine 5 that has fallen into the groove is moved laterally by the lateral movement mechanism 12, and the magazine 5 held in the notch groove 12a on the distal end side is moved laterally by the lateral movement mechanism 12. It is gripped by the gripping arm 2.

Next, when the lateral movement mechanism 12 descends downward, the two rear magazines 5 are moved to the stacker 11a.

This is left in the groove of the guide plate 13 arranged below the guide plates 11b and llc.

On the other hand, the gripping arm 2 receives the magazine 5 on the distal end side from the lateral movement mechanism 12 and holds it. Then, by driving the -L upward moving mechanism 9, it rises toward the position of the IC feeding section 4.

Next, as shown in FIG. 4(d), the lateral movement mechanism 12
It retreats from the position shown in FIG. 4(C) and then rises to reach the initial state shown in FIG. 4(a).

On the other hand, the gripping arm 2 that has risen to the IC feeding section 4 of the IC handler is locked at one end by the stopper 8 (
or the end of the magazine 5 on the ICC feeding section side is locked)
, the gripping arm 2 is rotated by further rising to -,
The magazine 5 is rotated and joined to the guide rail 4a.

Now, with this configuration, the position of the lateral movement mechanism 12 can be lower than the position of the IC feeding section 4 of the IC handler. Therefore, stacker 11al 1 lb+
The height of l lc can be selected to be the same as the conventional one or even lower regardless of the position of the feeding section even if it is at a high position, and can be set to a position with good workability.

FIG. 5 shows another vertical movement mechanism 91,
In this vertical movement mechanism 91, instead of the stopper 8, the gripping arm 20 is cam-engaged with the groove to prevent one end of the magazine 5 on the IC feeding section 4 side from rising.

In the figure, the gripping arm 20 is driven by a belt-type vertical movement mechanism shown in FIG. 3 using a support column 30 installed in the base 1 as a guide, and moves up and down.
It has a protruding end portion 21 that protrudes toward the IC feeding section 4 side.

A roller 22 (indicated by a broken line) is pivotally attached to the tip of this protruding end 21 .

- On the other hand, the frame 31 is further attached to the support column 30 on the base 1.
A grooved guide plate 32 is attached to the frame 31, and the groove 3 is attached to the frame 31.
3 is parallel to the pillar 30 and is connected to the ICC of the IC handler.
A horizontal elongated groove 33a is closed at a position corresponding to the upper part of the feeding section 4.

The roller 22 is fitted into this groove 33, and when the gripping arm 20 is raised, the end of the gripping arm 20 on the ICC feeding section side is When locked, the gripping arm 20 is positioned so as to be inclined at a predetermined corresponding angle and joined to the guide rail 4a as shown by the broken line at the position of the IC feeding section 4.

In this way, the IC magazine is tilted by preventing the upward movement of the gripping arms 2, 20 or the end of the magazine 5 located on the side of the IC feeding section 4 and moving the magazine 5 upward by a predetermined distance. However, the mechanism for rotating the gripping arms 2, 20 can be configured with various rotation mechanisms including a combination of a cam mechanism, an actuator, and the like. Various methods can be considered for blocking one end of the gripping arm or the magazine, and the method is not limited to the stopper or groove described above.

By the way, as in this embodiment, if the magazine is rotated upward from the horizontal position by gripping one end on the IC feeding section side, the rotation stroke can be shortened, and the entire mechanism can be simplified and miniaturized. . Furthermore, by gripping the IC feeder at the end, even magazines of different lengths can be used in common, eliminating the need for adjustment of the device.

Furthermore, by locking one end of the gripping arm or the magazine, it is possible to move in one direction and tilt it in one stroke, which has the advantage of shortening the time required to supply ICs.

As described above, in the embodiment, the gripping arm grips and rotatably holds the end of the magazine 5 on the IC feeding section side, and is tilted to correspond to the guide rail of the IC handler. However, this requires grasping the rear end of the magazine and
It is also possible to raise the IC feed section of the C handler higher than the IC feeding section, rotate it, and tilt it.Also, hold the magazine at two or more points and rotate it so that the magazine tilts. You can also do this.

[Effects of the Invention] As can be understood from the above description, in the present invention, the movement preventing means provided corresponding to the IC feeding section of the IC handler and the movement preventing means that rotate the IC magazine upward from the horizontal position The IC magazine is equipped with a magazine gripping mechanism that can grip the magazine, and a moving mechanism that moves the gripping mechanism up and down. The IC is placed in a plane whose longitudinal direction is substantially perpendicular to the IC feeding section, and the end of the IC magazine or gripping mechanism is engaged with the movement limiter.
The end of the magazine located on the IC feeding section side is prevented from moving upward, and the IC magazine is raised a predetermined distance to tilt the IC magazine, and the inserted IC is fed into the IC. Since the IC feeding section of the IC handler and the position of the stacker can be separated from each other, the height of the stacker can be freely set.

Furthermore, since a movement blocking means is provided, the magazine can be supplied to the IC handler side with one stroke, allowing efficient inspection.

As a result, even if the IC feeding section of a large IC handler is located at a high position, the stacker does not need to be placed high, and the height of the stacker is not restricted, allowing for easy workability. can be placed in
