In the packaging process of the carrier tape, the encapsulated carrier tape is generally fixed on the carrier tape tray through the winding mechanism. The carrier tape tray is a winding disc for fixing the carrier tape rising in the 1990s. It has a disc shaft and a positive disc surface and a reverse disc surface arranged at both ends of the disc shaft.

At the same time, the circumferential direction of the disc shaft is provided with a pin groove for fixing the carrier tape. During the use of the tape tray, the tape tray is usually clamped by the mechanical claw, then the tape on the carrier tape tray is manually pulled out, and finally the tape is installed on the machine. The tape tray is used. However, during the use, the tape remover cannot confirm the positioning position of the carrier tape tray, because the final position of the tape winding on the tape tray is certain, Therefore, the starting position of the tape on the tape tray cannot be determined.
