The main function of the Yamaha SMT machine 8MM feeder is to install SMD patch components on the feeder, and the feeder provides components for the SMT machine for patching1. The feeder identifies the type, size, pin direction and other information of the component through internal sensors or cameras and other devices, and transmits this information to the control system of the SMT machine. The control system calculates the precise position of the component based on this information to ensure that the pin direction and position of the component are accurate.
The specific workflow of the feeder in the SMT machine includes the following steps:
Component loading: Load the electronic components into the feeder in a certain arrangement, usually by fixing the components on the tape, and the tape is then installed on the shaft of the feeder.
Equipment connection: The feeder is connected to the SMT machine to ensure the synchronization of signal transmission and mechanical movement.
Component identification and positioning: The feeder identifies the type, size, pin direction and other information of the component through sensors or cameras, and transmits this information to the control system of the SMT machine.
Component picking: The SMT head moves to the specified position of the feeder according to the instructions of the control system to pick up the component. Component placement: The placement head places the component on the pad of the PCB and ensures that the pins of the component are aligned with the pad. Reset and cycle: After completing a component placement, the feeder automatically resets to the initial state and prepares for the next component pickup. The whole process is cycled under the command of the control system. Feeders include electric drive, pneumatic drive and mechanical drive. Among them, electric drive has small vibration, low noise and high control accuracy, so it is more common in high-end placement machines.
