DETAILED DESCRIPTION OF THE INVENTION A TCP handler of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic configuration diagram of a reject punch unit (punch device) which is a characteristic part of the TCP handler of the present invention. Here, FIG.
The reject punch unit is installed in the reject punch unit 30 described in the TCP handler 100 (TCP measurement system S) shown in FIG. 3, and is the same as the component shown in FIG. 1 in the following description. Or, the description of the equivalent components will be simplified or omitted.

In FIG. 1, a reject punch section (punch device) 30 is provided in the traveling path of the TCP handler 100, and has a punch drive (punch device) 31 capable of punching TCP from the upper surface of the TCP tape 1. The unit (punch device, moving device) 40 is provided on the side opposite to the punch 31 with the TCP tape 1 interposed therebetween so as to be movable in the contacting and separating direction with respect to the lower surface of the TCP tape 1.
And a die (supporting device) 32 capable of supporting the lower surface of the. Here, the TCP tape 1 has a punch 31 and a die 3.
It runs between 2 and the front side of the paper (+ X direction).

The punch driving unit 40 includes a base 41, a cylinder body 42 fixed to an upper portion of the base 41, a rod 43 arranged below the base 41 and capable of moving in and out of the cylinder body 42 at a predetermined stroke. The punch 31 is provided below the base 41. An air cylinder is configured by the cylinder body 42 and the rod 43, and the rod 43 moves in the axial direction (vertical direction in the drawing) with respect to the cylinder body 42. Punch drive unit 4
The base 41 of No. 0 has a through hole 41a, and through the through hole 41a, the base 41 can be slid vertically by a slide guide 50 provided in the base B extending vertically. It is supported. At this time, since the cylinder body 42 is fixed to the base 41 with its axial direction being the vertical direction, the cylinder body 42 fixed to the base 41 is
It is supported by the slide guide portion 50 so as to be movable in the axial direction. Further, the punch 31 attached to the base 41 is movable in the vertical direction with the movement of the base 41 in the vertical direction, that is, it is movable in the contacting / separating direction with respect to the upper surface of the TCP tape 1.

The die 32 is integrally fixed to the punch guide portion 45 via a connecting member 44. The punch guide portion 45 has a guide hole portion 45a that guides the punch 31, and the punch 31 is vertically movable while being guided inside the guide hole portion 45a as the base 41 moves. Further, the connecting member 44 has a through hole portion 44a, and through this through hole portion 44a, it can be slid vertically with respect to a slide guide portion 50 provided in the base portion B extending in the vertical direction. It is supported. And the dice 32
Since the connecting member 44 and the punch guide portion 45 are integrally fixed, the die 32, the connecting member 44, and the punch guide portion 45 integrally slide in the vertical direction with respect to the slide guide portion 50, and 32 moves toward and away from the lower surface of the TCP tape 1.

The upper surface of the punch guide portion 45 is fixed to the rod 43. Therefore, the movement of the rod 43 causes the punch guide portion 45 to move in the vertical direction. And
Since the punch guide portion 45 and the die 32 are integrally fixed via the connecting member 44, the die 32 also moves vertically while being guided by the slide guide portion 50 by the movement of the rod 43.

A stopper member 5 for restricting upward movement of the punch guide portion 45 is provided in the middle of the slide guide portion 50.
1 is provided. Since the punch guide portion 45 is fixed to the rod 43, the stopper member 51 restricts the upward movement of the punch guide portion 45, so that the lot 43 moves in the insertion direction from the most protruded position with respect to the cylinder body 42. Is restricted at a predetermined height position.

Further, between the base 41 fixed to the cylinder body 42 and the stopper member 51, the base 41 is provided.
A spring (urging member) 52 having an urging force in a direction in which the stopper member 51 and the stopper member 51 are separated from each other is provided. The urging force of the spring 52 prevents the base 41 from dropping downward.

Next, the operation of punching out a TCP judged to be defective by the test apparatus 200 by the reject punch section 30 of the TCP handler 100 having the above-mentioned configuration will be described with reference to FIG. TCP handler 1
The TCP tape 1 is intermittently fed by 00, and the test apparatus 200 tests the TCP in a stopped state. The test result is output to the control device CONT.

TCP tested by the test apparatus 200
Are transferred to the reject punch unit 30. At this time (when the TCP tape 1 is running and before the punching operation), FIG.
As shown in (a), the rod 43 of the air cylinder is in the most extended state (the downwardly extended state) from the cylinder body 42 and is connected to the rod 43 via the punch guide portion 45 and the connecting member 44. The die 32 is also in a state of being moved downward. Therefore, die 32 and T
It is separated from the lower surface of the CP tape 1.

When the TCP judged to be defective by the test apparatus 200 is transferred to the reject punch section 30, TC
The P handler 100 stops the running of the TCP tape 1 under the control of the control device CONT. Then, the reject punch unit 30 starts the punching operation under the control of the control device CONT. First, as shown in FIG. 2B, the rod 43 of the air cylinder moves up. When the rod 43 moves upward by a predetermined distance L1, the die 32 moves to T
The lower surface of the CP tape 1 is contacted and supported, and the punch guide portion 45 and the stopper member 51 contact. At this time, the predetermined distance L1 is smaller than the stroke L of the rod 43. The die member 32 is set at a predetermined position in the height direction by hitting the stopper member 51 and the punch guide portion 45. Here, the die 32 is set to be close to the lower surface of the TCP tape 1. That is, the stopper member 5
1 regulates the movement of the rod 43 from the most extended position with respect to the cylinder body 42 in the insertion direction (upward in the drawing) at a predetermined position (position where the die 32 is close to the lower surface of the TCP tape 1).

Next, when the upward movement of the rod 43, that is, the upward movement of the die 32 is restricted by the stopper member 51, as shown in FIG. While the movement of the rod 43 is restricted by the member 51, only the remaining stroke L2 (= L-L1) after the rod body 43 is supported by the slide guide portion 50, the cylinder body 42 overcomes the urging force of the spring 52 and moves downward. . Then, the base 41 and the punch 31 connected to the cylinder body 42 also move downward. The lowered punch 31 approaches the upper surface of the TCP tape 1 and punches out the TCP.

As described above, by the cylinder body 42 and the rod 43, the slide guide portion 50, the base 41, the punch guide portion 45, the connecting member 44, and the stopper member 51,
The die (supporting device) 32 is separated from the lower surface of the TCP tape 1 while the TCP tape 1 is running, and the die 32 is supported close to the lower surface of the TCP tape 1 during the punching operation by the punch 31. Moving device 300 that moves
Is configured.

When the punching operation is completed, the rod 43 descends, the die 32 descends accordingly, and the punch 31 ascends to return to the original standby position.

As described above, when the TCP device is punched out, by supporting the lower surface with the die 32,
The TCP tape 1 does not warp as the punch 31 descends. Therefore, the force due to the warp of the TCP tape 1 does not act on other TCPs adjacent to the TCP to be punched. Therefore, it is possible to prevent the force for punching out the bad TCP from adversely affecting the good TCP. Also, while the TCP tape 1 is running, the die 32 is TCP
Since it is separated from the tape 1, the TCP mounted on the TCP tape 1 does not interfere with the die 32,
Stable running can be realized.

TCP tape 1 for die 32 and punch 31
Since the moving operation in the contacting / separating direction and the punching operation of the punch 31 are controlled based on the test result of the test apparatus 200, the defective TCP can be reliably rejected based on the test result.

TCP tape 1 for die 32 and punch 31
Since the TCP handler 100 stops the running of the TCP tape 1 in the moving operation in the contacting / separating direction with respect to and the punching operation of the punch 31, the non-defective TCP mounted on the TCP tape 1 does not receive an impact from the die 32. Also, a bad TCP is punched after being stably supported.

Dice 3 from below with respect to TCP tape 1
After the two are brought into contact with each other, the punch 31 approaches the TCP tape 1 from above, so that the TCP tape 1 can be reliably supported by the die 32 during the punching operation of the punch 31. Therefore, the punching operation is stable.

Further, in the present embodiment, one cylinder serves both the approaching operation of the die 32 and the approaching operation of the punch 31 with respect to the TCP tape 1, so that the apparatus structure can be made simple and compact.

Base 41 fixed to cylinder body 42
By providing the spring 52 between the stopper member 51 and the stopper member 51, the base 41 does not drop during the non-punching operation,
During the punching operation, the die 32 can be brought closer to the TCP tape 1 and then the punch 31 can be brought closer to the TCP tape 1 by one cylinder.

[0043]

When the TCP device is punched out, the TCP
Since one side of the tape is supported by the supporting device, the TCP tape does not warp due to the operation of the punching device. Therefore, the force due to the warp of the TCP tape does not act on other TCPs adjacent to the TCP to be punched, and the force when punching a predetermined TCP is different from that of other TCs.
It is possible to prevent P from being adversely affected. Further, since the supporting device is separated from the TCP tape during the traveling of the TCP tape, the TCP mounted on the TCP tape and the supporting device do not interfere with each other, and stable traveling can be realized.
