[0002] In the production process of SMT patch, it is usually necessary to use flying dart, which can feed the strip-shaped material. In the production process of flexible circuit board, it is necessary to use a mounting machine to mount SUS, PI, PSA and label. The mounting machine includes a material feeder (automatic feeding flying dart), an FPC conveying and positioning device, a mounting head and an X-Y axis platform. The mounting head sucks the material from the feeder (automatic feeding flying dart) and mounts it on the FPC board of the FPC conveying and positioning device.

[0003] In the conventional flying dart, the material tray needs to be replaced manually. During the manual replacement process, the two ends of the material connecting belt wound on the outer wall of the material tray need to be connected. That is, the operator needs to remove the material connecting belt wound on the previous material tray and connect it with the end of the next material tray. Usually, the operator will connect the material connecting belt when there is still some remaining on the previous material tray. After the connection is completed, the operator needs to re-wind the remaining material connecting belt on the new material tray and then reinstall the material tray at the material tray position. In this process, the operator not only needs to connect the material connecting belts, but also needs to wind the material connecting belt on the new material tray, which takes a lot of time and slows down the replacement speed of the material trays. Therefore, we propose a kind of SMT patch feeding mechanism. SUMMARY
