First, most of the structure of functional placement machine adopts arch frame structure, which has the characteristics of high precision and good flexibility.
Second, in the X and Y positioning system most use fully closed-loop servo motor drive, with linear scale encoder for direct position feedback, to avoid errors due to the twisted deformation of the filament rod. Some in the y-axis using double motor and double screw in both sides of the platform drive, and use double linear scale for feedback, can effectively reduce the waiting caused by the static of the mounting head, reduce the error caused by the deformation of the beam asynchronous. There are more advanced use of linear magnetic levitation motor, in addition to the technical characteristics of each double drive, but also has a direct drive, mechanical structure less wear and tear, fast feedback, quiet, easy maintenance and high precision characteristics.
Fourth, it can accept all kinds of material packing methods, such as tape packing, tube packing, box packing and tray packing. In addition, when the tray is loaded with more materials, it can be equipped with multi-layer special tray feeder.
Fifth, in addition to the traditional vacuum nozzle can be used in the material suction, and for shaped more difficult to absorb the components can be used special nozzle, in addition, for the vacuum nozzle can not absorb the components can use pneumatic jaws.
Sixth, the components in the correction of the general use of upward-looking camera, with front light, side light, backlight and online light and other functions, can identify a variety of different components. If the component's size is too big, exceeds the camera's one view image (FOV), the upper view camera can also be analyzed and corrected through multiple view images after taking pictures comprehensively. Some multi-functional mounter's mount head is also equipped with mount head moving camera, can identify the smaller various components.
