On the other hand, as shown in Figure 2 is attached to the four pieces of tape of short length. Accordingly, as shown in FIG. 10A, the tape grip part 132 is used to grasp the end of the tape T, and then as shown in FIG. 10B, the tape is moved horizontally by the required length to release the tape. Then, as shown in Figure 10c, using the lifting roller 142 and the pressing support bar 144 to keep the tape taut. At this time, the pressing support bar 144 is composed of 4 pieces unlike the short side work. Then, as shown in FIG. 10D, the tape is quartered using four cutting units 146. When the cutting of the tape is completed, as shown in FIG. 10E, the pressing support bar 146 is moved, and then the tape attaching robot 150 is moved to the taping stage to proceed with the attaching operation.

According to the present invention, not only can the tape attaching process manually proceeded automatically, but also the continuous process can be performed while moving the chassis at a constant speed on the conveyor, thereby reducing the processing time and ensuring the accuracy of the work. There is an effect that can increase the efficiency.
