1, the base - used to install and support all parts of the SMT mounter, currently tend to use cast iron parts. Cast iron has a large mass, small vibration characteristics, is conducive to ensuring the placement accuracy.
2, feeder - feeder used to place a variety of packaging forms of components, bulk, braided tape, tube and tray four types. When mounting the various types of feeders are installed to the corresponding feeder rack.
3, printed circuit board transfer device - most of the current SMT mounter directly using the rail transmission, there are some SMT mounter using the table transmission, that is, the PCB is fixed on the table, the table in the transmission track running.
4, SMT mounting head - mounting head is the most complex, the most critical components on the SMT mounter, it is equivalent to the robot, used to pick up and put components.
5, the mounting head of the x, y positioning transmission device - there are mechanical screw transmission (generally used DC servo motor drive); magnetic scale and grating transmission. Theoretically, the magnetic scale and grating transmission accuracy is higher than the screw transmission; but in terms of maintenance and repair, the screw transmission is easier.
6, mounting tools (suction nozzle) - different shapes and sizes of components to be used in different suction nozzle pick and place, the general components using a vacuum suction nozzle, for shaped components (such as connectors without sucking the plane, etc.) are also used in the mechanical claw structure.
7, centering system - mechanical centering, laser centering, laser plus visual centering, and full visual centering system.
8, computer control system - computer control system is the command center of all operations of the mounting machine, most of the current SMT mounter computer control system using Windows interface.
