[0002] PCB board is an indispensable part of circuit components. During the production and processing of PCB board, chip mounting machine is needed to mount chip. The chip mounting machine is a device that transports the PCB board to the specified position and then accurately places the surface mount components on the PCB board by moving the mounting head. The mounting position of components is an important factor affecting the quality of PCB circuit board. When the chip mounting machine mounts chips on the PCB board, it will use the feeder to load the materials. The feeder is an important loading equipment on the chip mounting machine. However, when the PCB board is proofed or the amount of PCB boards processed is small, the feeder feeder has a high degree of wear and tear, so it is easy to affect the yield of the PCB board.
