Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention is directed to a TAB test device, and more specifically, to a TAB test device that prevents the TAB test device from stopping due to a malfunction of a detection sensor of a tension mechanism caused by loose winding of the TAB on a reel. Regarding

[0002]

[Prior art]

 The TAB is, for example, as described in Japanese Patent Application No. 63-155847, in which a semiconductor chip is formed on a tape-shaped film. The configuration of a TAB test device for testing such a TAB will be described with reference to FIG. In FIG. 3, 21A, 21B, 22A and 22B are rollers, 1A and 1B are reels, 24A and 24B are sprockets, 25 is TAB, and 26 is a measuring unit.

The test apparatus shown in FIG. 3 is bilaterally symmetric, and the TAB 25 can be transported in the right direction or the left direction. For example, the TAB 25 before the test is wound around the reel 1A, and the TAB 25 whose measurement is completed by the measuring unit 26 is wound around the reel 1B. The sprockets 24A and 24B carry the TAB 25 from the reel 1A to the reel 1B.

Next, the configuration of the roller 21A portion of FIG. 3 will be described with reference to FIG. When the TAB 25 is transported and positioned, a certain amount of tension is applied to the TAB 25 in order to prevent the TAB 25 from bending and waviness.

In FIG. 4, 27A is a roller guide, 28A is a pulley, 29A is a rope, and 30A is a weight. With this configuration, the roller 21A is constantly given a tension of 30A for the weight.

The configuration of the TAB test apparatus using this tension mechanism will be described with reference to FIG. In FIG. 5, 31A and 32A are sensors, 33A is a tape break detection sensor, and 34A is a detection plate attached to the roller 21A.

When the reel 1A is fixed and the TAB 25 is transported to the right by the sprocket of 24A, the roller 21A also follows and moves to the right, and the detection plate 34A is detected by the sensor 31A. At this time, the reel 1A starts rotating in the feeding direction of the TAB 25 at a speed higher than the carrying speed of the TAB 25.

FIG. 6 is a state diagram in which the roller 21A is moved leftward from FIG. As shown in FIG. 5, when the reel 1A rotates, the roller 21A moves leftward regardless of the feeding of the TAB 25.

FIG. 7 is a state diagram in which the roller 21A is moved further leftward from FIG. As shown in FIG. 7, when the detection plate 34A is detected by the sensor 32A, the reel 1A stops regardless of the feeding of the TAB 25. By transporting the TAB 25 from FIG. 7, the roller 21A moves to the right until the state of FIG. 5 is reached. The above contents described with reference to FIGS. 3 to 7 are described in the specification of Japanese Patent Application No. 2-41356 filed earlier by the applicant of this application.

[0010]

[Problems to be solved by the device]

 In the prior art shown in FIG. 7, the reel 1A is always stopped by the detection plate 34A being detected by the sensor 32A, but when the TAB 25 is broken, the roller 21A moves further to the left. The detection plate 34A is detected by 33A and the test apparatus itself is stopped.

However, in the conventional technique, even though the reel 1A is stopped, the roller 21A moves leftward in addition to the TAB 25 being cut, and the tape break sensor 33 detects the detection plate 34A. Sometimes. This state is referred to as "erroneous tape break detection" in this specification, and will be described in detail below.

FIG. 8 is a cross-sectional view of the reel rotating unit, in which 1 is a reel, 2 is a reel shutter, 3 is a key to enter a key groove, 4 is a stopper for fixing the reel, 5 is a collar for adjusting the reel width, 6 is a plate, 7 is a rotating shaft, 8 is a guide shaft, and 9 is a spring.

The plate 6 guides the four guide shafts 8 to constantly push the reel 1 toward the stopper 4 by the spring 9. The collar 5 serves as an adjusting spacer when the width of the reel 1 is changed, and the collar 5 and the plate 6 sandwich the reel 1.

The reel shaft 2 is further connected to a rotating shaft 7 which is connected to a motor (not shown). The key 3 guides the key groove 13 of the reel 1, and the reel shaft 2 is rotated to rotate the reel 1.

Next, returning to FIG. 7, an explanation will be given on the occurrence status of the false tape breakage detection. When the reel 1A rotates and the detection plate 34A is detected by the sensor 32A, the reel 1A stops, so that the roller 21A also tries to stop. When TAB25 is loosely wound around the reel 1A in this state, the reaction force of the force for stopping the roller 3A (the force for the roller 3A to move to the left) causes the TAB 25 to maintain the current state. Outperform the force (the force to hold the loosely wound state). Therefore, the TAB 25 is dragged out from the reel 1A, and the roller 3A does not stop and moves further to the left.

Here, when the TAB 25 is pulled out by 20 mm, the roller 21A further moves to the left by about 10 mm from the sensor 32A. If the distance between the sensor 32A and the tape breakage detection sensor 33A is within 10 mm, the detection plate 34A is detected by the tape breakage detection sensor 33A, and the tape breaks, and the test apparatus stops.

In order to avoid such “erroneous tape break detection”, for example, it is conceivable to extend the distance between the sensor 32A and the tape break detection sensor 33A, but the device itself becomes large accordingly. Further, since the degree to which the TAB 25 is loosely wound around the reel 1A cannot be grasped, there is a drawback that the dimension between the sensors cannot be specified. Therefore, it is not possible to solve the drawbacks of the prior art by simply extending the distance between the sensor 32A and the tape breakage detection sensor 33A.

The present invention solves the above-mentioned drawbacks of the prior art, and provides a TAB test device with an erroneous tape break detection prevention mechanism that can prevent “erroneous detection of tape break” without increasing the size of the device itself. The purpose is to provide.

[0019]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention is directed to a TAB test apparatus that winds a TAB 25 around a reel 1 after measuring the TAB 25. The roller 21 that removes the bending and waviness of the TAB 25 by pulling it in a predetermined direction, and the sensor 33 that detects that the film-shaped tape on which the TAB 25 is formed is broken by detecting the moving direction of the roller 21. Have and. When the sensor 33 detects the roller 21, the TAB test device stops the sprocket 24 and rotates the reel 1 in the reverse direction. As a result, when the roller 21 is no longer detected by the sensor 33, the normal operation is performed. Return to.

[0020]

[Action]

 According to this invention, when the detection plate 34A is detected by the tape breakage detection sensor 33A, the device itself is not immediately stopped and the restoration operation is once performed. Stop the device. Further, when the tape is recovered by the recovery operation, since the tape break has not actually occurred, the tape break detection sensor 33A returns to the normal operation as an erroneous detection.

[0021]

Embodiment An embodiment of the TAB test apparatus according to the present invention will be described in detail with reference to the accompanying drawings. The configurations described with reference to FIGS. 3 to 8 are the same in this embodiment, and a duplicate description will be omitted here.

FIG. 1 is an explanatory view showing an embodiment of a TAB test device with a tape breakage erroneous detection prevention mechanism according to the present invention. In FIG. 1, reference numeral 40 denotes a drive system for rotating / stopping the sprocket 24 and for rotating / reversely rotating / stopping the reel 1. Reference numeral 42 is a control system for inputting detection signals from the sensors 31 and 32 and the tape breakage detection sensor 33, and controlling the drive system 40 accordingly.

The control system 42 is also connected to an alarm circuit 44, and when a tape break of the TAB 25 is detected, an alarm output control such as an audible signal sound or an alarm lamp is performed. In FIG. 1, the reference numerals "A" or "B" of the sprocket 24 and the sensors 31, 32, 33 are omitted because both the left half and the right half can be applied.

FIG. 2 is a flow chart showing the operation of this embodiment shown in FIG. The operation of this embodiment will be described with reference to FIGS. 1, 2 and 3. Note that this flowchart is the left half of FIG. 3 when the TAB 25 is conveyed from left to right as in FIGS. 4 to 7. In this operation example, FIG. 1 is also described as the left half, but the right half is also described. The same processing can be performed.

First, as a normal operation, while the reel 1A is stopped, the drive system 40 rotates the sprockets 24A and 24B counterclockwise to convey the TAB 25 to the right. At this time, the roller 21A also moves to the right until the detection plate 34A attached to the roller 21A is detected by the sensor 31A (S200).

Next, when the detection plate 34A is detected by the sensor 31A, the detection information is notified to the control system 42 at that time (S202). When the detection information is input from the sensor 31A, the control system 42 controls the drive system 40 to send the TAB 25, rotates the reel 1A clockwise, and sends the TAB 25. At this time, the roller 21A moves to the left until the detection plate 34A is detected by the sensor 32A (S204).

Next, when the detection plate 34A is detected by the sensor 32A, this detection information is notified to the control system 42 (S206). When the control system 42 receives the detection information from the sensor 32A, it instructs the drive system 40 to stop the reel 1A. As a result, the reel 1A stops and the roller 21A also tries to stop (S208).

At this time, the roller 21A may move to the left of the sensor 32 without stopping even if the tape is not broken. Therefore, next, it is confirmed whether or not the tape breakage detection sensor 33A detects the detection plate 34A in this state. Then, when the detection information of the tape breakage detection sensor 33A is not notified to the control system 42, the control system 42 continues the normal operation (S210). When the detection information of the sensor 33A is notified to the control system 42 (S210), the control system 42 controls the drive system 40 to stop the sprockets 4A and 4B (S212), and then the reel 1A. Is reversely rotated in the counterclockwise direction in which TAB5 is wound (S214).

Here, when the TAB 25 is actually cut, the roller 21A does not move from that position even when the TAB 25 is wound around the reel 1A, so the tape break detection sensor 33A remains in the state of detecting the detection plate 34A. (S216). The control system 42 stops the device for the first time, and issues an alarm output to the alarm circuit 44 to generate an alarm (S218).

On the contrary, when the tape break detection sensor 33A detects the detection plate 34A because the TAB 25 is loosely wound around the reel 1A, the roller 21A moves to the right when the TAB 25 is wound and the detection is performed. The plate 34A moves to the right of the tape breakage detection sensor 33A and is no longer detected by this sensor 33A. When the detection plate 34A is no longer detected by the sensor 33A, the reel 1A is reversely rotated until the detection plate 34A is detected by the sensor 32A as a tape breakage false detection. Then, the control system 42 returns to the normal operation when detected.

[0031]

[Effect of device]

 According to this invention, the device itself recognizes whether the tape break detection sensor is mistakenly detected by loosely winding the TAB on the reel or the tape is actually broken, and the erroneous detection is detected. In this case, it will be possible to automatically recover and prevent the device from being stopped unnecessarily. Further, it is also effective in preventing erroneous detection of the tape breakage detection sensor due to looseness of the reel shaft and the reel hob that rotate the reel 1.
