In this embodiment, a dual in-line type semiconductor device (E
An autohandler that performs measurement classification of FROM) will be explained.

This dual inline type electronic component (semiconductor device) 1
As shown in FIG. 5, the magazine has a structure in which a plurality of arms 3 are bent downward from both sides of the package 2, and a plurality of doors 3 protrude from both sides of the package 2, as shown in FIGS. Stick magazines) 4 are housed and managed in a row. The electronic component 1 is configured such that the lower surface of the pan cage 2 rests on a pedestal part 5 at the center inside the magazine 4, and both side glue portions 3 are accommodated in a lead accommodation space 6 extending on both sides of the pedestal part. In addition, the electronic component (semiconductor device) 1 basically rides on the pedestal and slides down the package surface due to its own weight in each mechanism described later, although it may not be particularly illustrated or explained. It is supposed to be done.

The autohandler that performs such characteristic classification of the electronic components 1 has a transport section 8 on the front side (front surface) of the autohandler main body 7, as shown in the schematic diagrams illustrating the outline of the autohandler in FIGS. 1 and 2. have. The conveying section 8 is composed of five sets of unit conveying sections 9, and the unit conveying section 9 has three units.
It consists of a book transport path 10. The transport paths IO both extend in parallel and in the vertical direction. electronic parts l
is supplied from the magazine 4 into the conveyance path 10 by the loader (distributor) 11, and slides down within the conveyance path 10 due to its own weight, as shown by the two-dot chain line frame in FIGS. 1 and 2. , the upper part of the special equipment section 12. before measurement. After being classified by the measuring section 132, it passes through the special equipment section 14, and then is housed in the magazine 4 by two unloaders 15 and transported to a desired section.

Next, each part of the autohandler will be explained with reference to each figure.

An example of the main body 7 (on the right side) is a magazine conveyance lift a16.
is installed. Although not particularly limited, this magazine conveyance elevator 16 consists of a chain conveyor 17, and lifts the elongated magazine 4 containing 13 electronic components 1 by horizontally supporting it by an attachment 18 attached to a chain (not shown). It is supposed to be done. A magazine 4 containing electronic components 1 is supplied and mounted on the upper rising side of the magazine conveying elevator 16.

On the supply and mounting side of the magazine 4, for example, 80 magazines 4 can be mounted, although this is not particularly limited. Further, the magazines 4 filled with electronic components 1 are clamped one by one by the distributor 11 and transported onto the transport path 10 of the unit transport section 9. Although the distributor 11 is not particularly limited in the unit transport section 9, it supplies five electronic components 1 to each of the transport paths 10 on both sides, and also transports empty magazines 19 to the top of the magazine transport elevator 16. Return it to the attachment 18 on the descending side.

The empty magazine 19 returned to the magazine transport elevator 16 is
The magazine is lowered by the intermittent drive of the magazine transport elevator 16, and is clamped again by the unloader 15 below. Empty magazine 19 held by unloader 15
are moved below each conveyance path 10 of the conveyance section 8, and receive the electronic component 1 sent out from the conveyance path 10 into an empty magazine 19.

Incidentally, when the distributor 11 and the unloader 15 clamp the magazine 4 or the empty magazine 19, the magazine 4 and the empty magazine 19 are clamped by the pushers 20 and 21, respectively.
The magazine 4 and the empty magazine 19 are moved horizontally by the forward movement of the magazine 19 so that the ends of the magazine 4 and the empty magazine 19 on the clamp side reach the clamp area of the distributor 11 and the unloader 15. Further, the rear end of the magazine 4 is closed with a stopper 22, as shown in FIGS. 1, 2, and 15, to prevent the stored electronic components 1 from falling out.

Furthermore, as shown in FIG. 2, the direction in which the distributor 11 clamps the magazine 4 and rotates it 180 degrees and the direction in which the unloader 15 clamps the empty magazine 19 and rotates it 180 degrees are opposite to each other. Become. For this reason, in order to make the magazine 4 and the empty magazine 19 appear on the same side in front of the handler body 7, the magazine transport elevator 16
A rotation correction mechanism 23 is provided in the middle. In this rotation correction mechanism 23, as shown in FIG. 16, a rotatable pushing plate 24 moves forward with respect to an empty magazine 19 that has been carried to an attitude correction position by a magazine conveying elevator 16. The empty magazine 19 is moved horizontally in the width direction of the chain conveyor 17. Due to this advancement, the empty magazine 19 is moved forward by the motor 25.
It enters a guide section 27 consisting of a tapered hole of a rotating body 26 that is controlled to rotate 80 degrees. The empty magazine 19 is inserted into the pushing plate 24.
toward the center of the guide portion 27 by the pushing movement.

As a result, the empty magazine 19 is lifted off the attachment 18 attached to a chino (not shown). The rotation correction mechanism 23 rotates the rotating body 26 by 180 degrees by the rotation of the motor 25, and changes the empty magazine 19, which was in the forward rotation state shown in FIG. 17, to the state shown in FIG. 18. Correct to reverse condition. The empty magazine 19 in the reversed state is moved back to the attachment 1 of the magazine conveying elevator 16 by the rotation of the rotating body 26 being stopped and the pushing plate 24 being retracted.
8 and is transported to a position where it is provided to the unloader 15 by the intermittent drive of the magazine transport elevator 16.

Further, the distributor 11 is configured to move along a pair of guide shafts 28 extending horizontally above the front surface of the handler main body 7 from the entire width area of the conveying section 8 to the installation area of the magazine conveying elevator 16. It has become. The distributor 11 has a main body 29
The upper part of the guide shaft 28 is fitted into the guide shaft 28 so that it can slide, and as shown in FIG. 2, it can reciprocate 90 degrees around the upper guide shaft 28.

Furthermore, as shown in FIG. 3, a guide hole 30 through which the electronic component 1 can pass is provided vertically in the main body 29 of the distributor 11. For convenience of explanation, this state is called the upright posture. Further, when the distributor 11 is in an upright state, the lower guide shaft 28 comes into contact with the inside of the distributor 11, so that the upright position of the distributor 11 is maintained. In contrast, the attitude when the distributor 11 grabs the magazine 4 from the magazine conveyance elevator 16 will be referred to as a horizontal attitude.

On the other hand, a pair of claws 31 for clamping the magazine 4 are provided at the intake port on the upper end side of the guide hole 30. One end of a sliding shaft 34 and a movable shaft 36 are fixed to the pair of claws 31. The sliding shaft 34 is slidably attached to a support block 32 fixed to the main body 29 via a linear bearing 33. Further, the movable shaft 36 passes through the support block 32, and one end is connected to the shaft of the air cylinder 35. Further, a compression coil spring 37 is attached to the movable shaft 36,
A pair of claws 31 always clamp the tip of the magazine 4 that is abutted against the periphery of the intake port of the main body 29. In this state, the electronic component 1 in the magazine 4 can be moved to the guide hole 30 without hitting the green of the guide hole 30 at the seam. Further, below the main body 29, as shown in FIGS. 3 and 4, a guide hole 30 is provided.
Stopper 38 for stopping the electronic component 1 housed therein
A pair of photosensors consisting of a light emitter 39 and a light receiver 40 are arranged at the lower end of the guide hole 30 to detect whether or not the electronic component 1 is present. The stopper 38
passes through a support arm 41 fixed to the outer wall of the main body 29 and the main body 29, and is connected to a rod of an air cylinder 42 attached to the support arm 41, and is connected to the guide hole by the "ON" operation of the air cylinder 42. It is designed to fall outside of 30. The stopper 3
A compression coil spring 43 is attached to 8, and the tip of the stopper 38 always protrudes into the guide hole 30.
The electronic component 1 accommodated within the guide hole 30 is pressed against the side wall surface of the guide hole 30, and the electronic component 1 accommodated within the guide hole 30 is stopped within the guide hole 30. On the other hand,
As shown in FIG. 4, a pair of stoppers consisting of a counting stopper 44 and a complete stopper 45 are arranged at the upper part of the conveyance path 10 on both sides of the unit conveyance section 9 that the distributor 11 faces. There is. The counting stopper 44 is located above, and when it protrudes into the transport path 1O, four electronic components 1 are placed in the transport path 10 above it, and the lower part of the fifth electronic component 1 is placed on top of it. It is placed in such a position that it can be barely entered. The complete delivery stopper 45 is located below the counting stopper 44, and the counting stopper 44 is located below the counting stopper 44.
When the electronic component 1 is turned OFF and comes off the conveyance path 10, it is designed to support the electronic component 1 that has fallen, and the electronic component 1 is
Five electronic components 1 are supported and housed inside.

Here, the operation of distributing and supplying the five electronic components l into the transport path lO will be explained. First, as shown in FIG. 4, the counting stopper 44 and the complete delivery stopper 45
In the state in which the distributing device 11 protrudes into the conveyance path 10, the stopper 38 of the distributor 11 is turned “ON”. Then, distributor 1
The electronic components 1 housed in the electronic components 1 enter the transport path 10 in a minus row, and are stopped when the lowest electronic component 1 hits the counting stopper 44 and comes to rest. Thereafter, the stopper 38 is in the "OFF" state,
The stopper 38 projects into the conveyance path 10 again. At this time, in the initial distributed supply state, as shown in Figure 3,
Since 13 electronic components 1 are accommodated, the transport path 10
Four electronic components 1 are completely inserted into the interior, and a fifth electronic component 1 is positioned between the conveyance path 10 and the distributor 11. Further, the stopper 38 presses the sixth electronic component 1 from the bottom against the inner wall of the guide hole 30 to stop the sixth electronic component 1 in the guide hole 30.

On the other hand, in this state, the light 46 emitted from the light emitter 39
hits the fifth electronic component 1 from the bottom and does not reach the light receiver 40. As a result, five electronic components 1 that can fall under their own weight are placed on the counting stopper 44, so the counting stopper 44 is turned "OFF" based on the output signal of the light receiver 40 and the counting stopper 44 is turned off. The stopper 44 is now removed from the conveyance path 10. Counting stopper 44
The electronic component 1 supported by the counting stopper 44
As the support is lost due to the retracting action, it falls under its own weight and moves onto the fully loaded stopper 45 below. After supplying this electronic component 1, the distributor 11 moves onto the next conveyance path 10.

In addition, at the time of the third supply, as shown in Fig. 4,
Only three electronic components 1 are supplied in the magazine 4.

As a result, the light 46 emitted from the emitter 39 is transmitted to the receiver 4.
0 and an insufficient supply condition is detected, the distributor] 1 runs towards the magazine transport elevator 16, places the empty magazine 19 on the attachment 18 on the lowering side of the magazine transport elevator 16, and moves the empty magazine 19 onto the attachment 18 on the lower side of the magazine transport elevator Magazine 4 fully filled with electronic components 1 on attachment 18 of
to clamp. During this time, the counting stopper 44 maintains a state of protruding into the transport path 10 and supports the three electronic components 1. Thereafter, the distributor 11 that has returned to the predetermined conveyance path 10 operates the stopper 38 "ON" again to distribute and supply the electronic component 1 in the guide hole 30 into the conveyance path 10.

Through this distributed supply, five electronic components 1 are supplied into the conveyance path 10 in the same manner as described above. In this way, five electronic components 1 are sequentially supplied into the transport paths 10 on both sides of the unit transport section 9.

On the other hand, as shown in FIG. 6, the complete delivery stopper 45 moves along the guide shaft 47 while supporting the electronic component 1, and carries the electronic component 1 to the special equipment section 12 before measurement. Thereafter, the complete delivery stopper 45 is removed from the transport path 10, and the five electronic components 1 are sent one by one to the measuring section 13 by an individual feeding mechanism (not shown). Measuring section 13
As shown in Figure 7, there are 5 wires (3 wires in the figure).
A stopper 48 is provided. That is, five classification pieces 49 are arranged along the conveyance direction in corresponding portions of the measuring section 13 in the middle of the conveyance section 8, and each of the classification pieces 49 is provided with a stopper 48, respectively. As shown in FIGS. 8 and 9, the classification piece 49 is provided with three passage holes 52 between a main body 50 and a guide 51 facing the main body 50. These passage holes 52 correspond to the three conveyance paths lO of the unit conveyance section 9, and the electronic component 1 can pass through these passage holes 52. Further, each classification piece 49 is supported by a pair of sliding shafts 53 extending in a direction perpendicular to the conveyance path 10. These sliding shafts 53 are attached to the support block 54 via linear bearings 55 so as to be slidable in the axial direction. Although not shown, the pair of sliding shafts 53 are controlled by a switching mechanism to freely switch between the conveying paths at a pitch that makes the interval between the conveying paths 10 one pitch. Further, the stopper 48 is disposed below the passage hole 52 on the sliding shaft 53 side.

By the way, the measuring section 13, to put it more directly,
The measurement sockets are arranged side by side at positions facing the central conveyance path 10 in the unit conveyance section 9 . Furthermore, the measuring section 13 is supported by a support plate 56 and is pushed by a pressing block 57 so as to come into contact with the leads 3 of the electronic component 1 . After the measuring section 13 contacts the lead 3, a writing/reading test is performed on the electronic component 1, for example, 120 seconds later. Then, the electronic components 1 are classified based on the measurement results. Classification is performed, for example, into three classifications: A classification, 8 classification, and C classification.A classification is considered to be a non-defective product, 8 classification is a re-inspected product, and C classification is a defective product. Sorting into these A, W, 8 classifications, and C classification is carried out by the unit transport section 9.
Three transport paths 10 are used. That is, by switching the three transport paths 10 of the sorting frame 49 and releasing the stopper 48 by turning the stopper 48 "OFF", the electronic component 1 in the sorting frame 49 is transported to a predetermined one of the three transport paths 10. Send it into Route 10.

Next, with reference to FIGS. 1O to 14, the electronic components 1 are supplied to the sorting frame 49, and the electronic components 1 are measured and classified into two categories.

I will explain about the removal. Note that A and B in FIGS. 1 and 2 and FIGS. 10 to 14.

C indicates A classification, 8 classification, and C classification, respectively.

When electronic components 1 are supplied to each unit transport section 9, the group of classification pieces 49 is arranged as shown in FIG. That is, the five classification pieces 49 at the top are located on the C category on the right side, with the passage hole 52 portion provided with the stopper 48, and the five classification pieces 49 at the bottom are placed on the B category on the left side. The portion of the passage hole 52 where the stopper 48 is disposed will be located. Note that the X-marked locations shown in FIGS. 10 to 14 indicate that the electronic component 1 is accommodated.

Next, after the electronic components 1 discharged one after another from the special equipment section 12 of the unit transport section 9 before measurement are stored in a predetermined section of each classification piece 49, as shown in FIG. Each classification frame 49 has a transport path 1 for classification A in which the electronic component 1 is in the center.
Can be switched one pitch above 0. And in this state 5
Measurement of 0 electronic components 1 is performed simultaneously. In addition, when measuring the electronic components 1, the electronic components 1 are sequentially supplied into the empty special equipment section 12 by the distributor 11, and if there are electronic components 1 in the special equipment section 14 after classification, the unloader It is unloaded by 15.

When the measurement of the electronic component 1 is completed, the classification frames 49 are switched and classified based on the information.

That is, as shown in FIG. 12, the classification piece 49 holding the electronic component 1 determined to be good is not switched and allows the electronic component 1 to face the transport path 10 of the A classification,
Only the classification piece 49 that accommodates the electronic component 1 determined to be a defective product or a re-inspected product moves one pitch. and,
In this state, the good electronic component 1 is "OF" of the stopper 48.
It is released by the "F" motion and moves into the transport path 10 of the A category in the center as shown by the arrow.

Next, in the classification frame 49 that had switched to the right side,
As shown in FIG. 13, the classification piece 49 that holds the re-inspected items is switched two pitches to the left, so that the electronic components 1 of the re-inspected items are placed on the conveyance path 10 of the three categories on the left, and the subsequent By turning off the stopper 48 in the sorting frame 49, the electronic components 1 are sent into the transport paths 10 of the three categories.

Next, as shown in Fig. 14, all the classified frames 4
9 moves to the right, and the electronic component 1 facing the conveyance path 10 of C classification on the right side is moved to the classification frame 49 that holds the electronic component 1.
When the stopper 48 is turned OFF, the paper is fed into the C-class transport path 10.

In this way, classification and selection are performed sequentially. In addition, in each classification sorting, the passage hole 52 serves as a guide for the electronic component 1.

On the other hand, the electronic components 1 that have been classified and sorted are transported to the unit transport section 9.
and into the special equipment section 14 after classification. The electronic components 1 transferred from the sorting frame 49 to the transport path 10 are transferred to the special equipment section 14 by a transfer mechanism as shown in FIG. 6, and then transferred by two unloaders 15 as shown in FIG. It is housed in an empty magazine 19 that is clamped to an unloader 15. 2 unloaders 15
basically has substantially the same structure as the distributor 11 described above. That is, one unloader 15 holds one empty magazine 19 and stores good electronic components 1 therein, and then transfers the magazine 4 to the good product storage box 58 . In addition, the other unloader 15 has five empty magazines 19.
electronic components 1 and 5 which are defective and re-inspected.
The book is stored in a predetermined empty magazine 19 among empty book magazines 19. Incidentally, the good product storage box 58 is controlled to move up and down by a lift cylinder 59, so that the magazine 4 is properly accommodated. Furthermore, since the frequency of occurrence of defective products and re-inspected products is extremely low, this handler can withstand long-term operation with only the empty magazine 19 held in the unloader 15. In addition, in the autohandler of the present invention, a magazine 4 containing defective products and re-inspected products is also provided.
There is no problem in arranging storage boxes in which the magazines 4 are placed and transporting the magazines 4 to these storage boxes (although longer operation is possible).

Next, the structure of such an unloader 15 will be briefly explained. Here, the unloader 15, which operates while holding one empty magazine 19, will be described. In addition, if the structural parts of the unloader 15 are exactly the same as the above-mentioned distributor 11, the part names used in the above-mentioned distributor 11 will be used,
We will also use the symbols as they are. Also, I will intentionally omit explanations of parts that can be understood without explanation.

The unloader 15 moves along a pair of guide shafts 60 that extend horizontally below the front surface of the handler main body 7, from an area where the good product storage box 58 is installed on one side of the transport section 8 to an area where the magazine transport elevator 16 is installed on the other side. It is designed to move over a period of time.

The upper part of the main body 29 of the unloader 15 is fitted onto the guide shaft 60 so that it can slide, and as shown in FIG. There is. Further, in the main body 29 of the unloader 15, as shown in FIG. 15, a guide hole 30 through which the electronic component 1 can pass is provided vertically. In this state, it is in an upright position similar to the distributor 11, but its direction is completely opposite. That is, like the distributor 11, the unloader 15 is provided with a pair of claws 31 for clamping the magazine 4 provided at the intake port at the upper end of the guide hole 30, but in the upright position, the distributor 11 It will be located at a lower position.

Further, if the distributor 11 rotates at 0@~906'', the unloader 15 rotates at 2706~360''.Therefore, correspondingly, the lower guide shaft 6
0 is the front side of the main body 29 at the front of the handler main body 7, and positions the unloader 15 in an upright position.

On the other hand, in the unloader 15, the position of the photo sensor consisting of the stopper 38 and the light receiver 40 is different, and
The position of the counting stopper 44 operated by the photo sensor differs. Note that the stopper 38 and the complete delivery stopper 45 that were present in the distributor 11 are replaced by the unloader 15.
is not provided. The stopper 38 and the light receiver 4
As shown in FIG. 15, the photo sensor consisting of 0 is provided at the upper end of the main body 29 when the unloader 15 is in an upright position, and is adapted to detect the presence or absence of the electronic component 1. There is. The counting stopper 44 is attached to a support arm 61 extending from the end surface of the main body 29 on the claw 31 side, and is adapted to protrude into the empty magazine 19 as necessary. Empty magazine 19 has 13
electronic components 1 are accommodated. The counting stopper 4
4, when this counting stopper 44 protrudes into the conveyance path 10, 12 electronic components 1 are placed on the area inside the empty magazine 19 on the counting stopper 44, and the lower part of the 13th electronic component 1 is placed on top of them. It is placed in such a position that it can be barely entered. The presence or absence of this 13th electronic component 1 is detected by a photo sensor consisting of the light emitter 39 and the light receiver 40. Since a maximum of 10 electronic components 1 are housed in the special equipment section 14 after the classification,
Even if the electronic component 1 is supplied from the classified special equipment section 14 to the empty magazine 19 by the "ON" operation of the stopper 62 disposed in the special equipment section 14 after classification, in this one feeding operation, Empty magazine 19 is not full.

Therefore, in this state, the light receiver 40 is connected to the light emitter 39.
The underfilling state is detected by receiving the light 46 emitted from the battery. While this underfilling state is detected, the counting stopper 44 protrudes into the empty magazine 19. Then, the unloader 15 moves and moves to another conveyance path 10.
Receives a new supply of electronic components 1 from. After the supply of new electronic components 1 is repeated, when the light 46 no longer reaches the light receiver 40, it means that the empty magazine 19 is filled with electronic components 1, and therefore the stopper 62 stops being transported. The fourteenth electronic component 1, counted from the bottom of the group of electronic components protruding into the path 10 and placed on the counting stopper 44, is stopped in the transport path 10.

After the stopping operation of the 14th electronic component 1, the counting stopper 44 is turned OFF and the tip of the counting stopper 44 is turned OFF.
9, that is, the electronic component 1 is removed from the fully filled magazine 4. As a result, the thirteen electronic components 1 that have been supported by the counting stopper 44 fall under their own weight and are placed on the bottom of the magazine 4, that is, on the stopper 22. Note that the stopper 62 may have the same structure as the stopper 38. In addition, the other unloader 15 that clamped five empty magazines 19 also clamped five empty magazines 19.
An unloader 15 that runs while ramping up one empty magazine 19, except for having a grip for final clamping.
is structurally the same.

Since sorting can be performed at high speed, equipment costs are low, and labor can be saved, etc., a synergistic effect can be obtained in that the cost of characteristic classification can be reduced.

Although the invention made by the present inventor has been specifically explained above based on Examples, it goes without saying that the present invention is not limited to the above Examples and can be modified in various ways without departing from the gist thereof. Nor. For example, as shown in FIG. 20, even if the passage holes 52 provided in the classification piece 49 are provided so that the electronic components 1 overlap, the same effect as in the above embodiment can be obtained. This embodiment shows an example in which two passage holes 52 are provided, and it is possible to classify the electronic components 1 into good and defective products. Further, in this embodiment, a stopper 48 for stopping the electronic component 1 is not shown, but may be provided on the side.

Further, in the embodiment, an example in which 50 semiconductor devices 1 are measured simultaneously has been described, but it is also possible to measure even more semiconductor devices, such as 100 or 200.
