In addition, the stopper block 27 is fixed to the first plate 18 so that only the first plate 18 moves in the initial state, and has a predetermined distance t from the second plate 23. ) Is provided with a drive cylinder 29 for moving the first and second plates 18 and 23.

On the other hand, the socket 3 in which the terminal pin 2 is fixed to four sides is provided in the position on the horizontal line of the PLCC 1 by which the transfer control was controlled by the stopper pin 11, and the lead 1b of the PLCC was connected. The guider 30 having a cutout portion 30a formed at a corner portion of the socket to pass through the connection portion 8c formed on the movable track 8 is fixed with a screw 31 to surround the terminal pin 2. At the inlet side of the guider 30, an inclined surface 30b is formed to prevent the positioning role and deformation of the terminal pins when the PLCC is inserted.

Referring to the operation, effects of the present invention configured as described above are as follows.

First, the initial state as shown in (a) of FIG. 4, that is, one PLCC that has been tested is sent out along the delivery track and the state immediately before one PLCC is supplied along the supply track is fixed to the mounting plate 28. The rod of the drive cylinder 29 is retracted so that the fixed track 6 and the movable track 8 are connected, and the rod 13 of the cylinder 15 fixed to the base 5 is advanced to stop the stopper pin 11. The spring 12 is exposed to the inside of the fixed track 6 and the movable track 8 by the elastic force of the spring 12 to close the feed path of the PLCC 1.

In this state, if one PLCC (1) is supplied along the supply track and caught on the stopper pin (11) that closed the transfer path of the PLCC, and the transfer is stopped, a separate sensor (not shown) detects this and installs the plate. Since the driving cylinder 29 fixed to the 28 is driven, the rod of the driving cylinder 29 and the fixed first plate 18 start to move to the right in the drawing while compressing the spring 25.

Accordingly, since the first shaft 19 and the push plate 17 fixed to the fixed track 6 are moved, the support block 16 moves the PLCC 1 to the movable track 8 as shown in FIG. Close support.

At this time, the second plate 23 is fitted to the stopper block 27 and does not move when the first plate moves by the distance t from the second plate 23.

If the drive cylinder 29 continues to operate in the state in which the support block 16 supports the PLCC 1 on the movable track 8 in the above-described operation, the stopper block 27 is connected to the second plate 23. Since it moves together with the first plate 18 in a connected state, the push plate 17 and the movable track conveying plate 21 fixed to the first shaft 19 and the second shaft 22 also move toward the socket 3 side. Is moved.

Accordingly, the PLCC 1 supported by the movable track 8 by the support block 16 gradually moves the movable track 8 connected to the movable track transfer plate 21 to the connecting piece 20 toward the socket 3 side. As it moves together, the long hole 8a formed in the movable track 8 is inserted into the guider 30 and the connecting portion 8c is inserted into the cutout 30a, so that the movable track 8 and the guider 30 are It does not cause mutual interference.

In this way, when the movable track transfer plate 21 moves to the right in the drawing according to the operation of the driving cylinder 29, the stopper pin 11 coupled to the fixed block 9 is also moved, so that the stopper pin 11 is moved to the guider ( It is moved to the position close to 30), and it becomes a state like (c) of FIG.

At this time, the engaging piece 10 fixed to the stopper pin 11 is in a state of being connected to the connecting piece 14 fixed to the rod 13.

In this state, if the stopper pin 11 continues to move to the socket 3 side, the stopper pin 11 collides with the socket 3, so that the cylinder 15 installed in the base 5 is operated by a separate sensor. do.

As a result, the connecting piece 14 fixed to the rod 13 is connected to the locking piece 10 to pull the stopper pin 11 to the opposite side of the socket 3, so that the stopper pin 11 stops the spring 12. Since the movable track 8 is moved to the socket 3 side due to the continuous operation of the drive cylinder 29 while being retracted while compressing, the PLCC 1 supported by the movable track 8 by the support rack 16 is the fourth. As shown in FIGS. 3D and 3, the lead 1b is connected to the terminal pin 2 by being fully inserted into the socket 3.

In this way, the PLCC 1 is inserted into the socket 3 while being supported by the connecting surface 8b of the movable track 8 by the support block 16 so that the lead 1b is connected to the terminal pin 2. Accordingly, the tester (not shown) connected to the socket 3 and the lead wire checks the performance of the PLCC 1 and informs the CPU (central processing unit) of the result.

When the performance test is completed by the operation as described above and the driving cylinder 29 operates to pull the rod, only the first plate 18 connected to the rod is to be moved to the opposite side of the socket 3 (left side in the drawing). The second plate 23 is also moved together with the first plate by the restoring force of the spring 26 provided between the second plate 23 and the sleeve 24.

Accordingly, the movable track 8 is moved to the opposite side of the socket 3 while the support block 16 fixed to the push plate 17 supports the PLCC 1 on the movable track 8. The PLCC 1 in close contact with the connection surface 8b of () is separated from the terminal pin 2 of the socket 3.

In this way, after the PLCC 1 is released from the socket 3, the movable cylinder 8 is moved to the fixed track 6 side, and the driving cylinder 29 continues to operate in the state of being connected to the fixed track, so that the first plate 18 ), The movable track 8 is connected to the stationary track 6 so that the transfer of the second plate 23 is stopped, and only the first plate 18 is moved to the left in the drawing so that the push plate 17 It is also reduced to the initial state so that the support block 16 releases the support state of the PLCC 1.

As a result, the PLCC 1 having completed the performance inspection is sent out to the delivery track side by its own weight, and is classified according to the inspection result by the classification unit.

After that, the cylinder 15, which is installed on the base 5 and retracts the stopper pin 11, operates to advance the rod 13, so that the pulling force of the engaging piece 10 pulled by the connecting piece 14 is reduced. The stopper pin 11 is released to the socket 3 by the restoring force of the spring 12 and is exposed to the inside of the fixed track 6 and the movable track 8 as in the initial state, so that the stopper pin 11 is supplied for the performance test. It is to control the transfer of the new PLCC (1).

What has been described so far is that one PLCC (1), which has been transferred to the hydration part, is supported between the movable track (8) and the support block (16), and then moved to the socket (3) side to perform a performance test. By explaining one cycle for transferring (1) to the delivery track side, the operation as described above is continuously and repeatedly performed as long as the PLCC 1 is supplied through the supply section.

As described above, the device of the present invention forms the cutout portion 30a in the guider 30 fixed to the socket 3 and the connection surface 8b and the connection portion 8c in the movable track 8 to perform the performance test. The lid 1b is connected to and disconnected from the terminal pin 2 by pushing it into the guider 30 with the support block 16 supported by the support block 16 on the connection surface 8b of the movable track 8. It is possible to realize the automation of the PLCC performance test, thereby greatly improving the productivity of the performance test.
