1. SMT Mounter frame
In the structure of SMT placement machine, the frame is the foundation of the machine, and all the transmission, positioning and transmission mechanisms are firmly fixed on it. At present, all kinds of frame can be divided into integral casting type and steel plate welding type. Since most types of mounter and its various feeders are also installed on it, the rack needs to have sufficient mechanical strength and rigidity.
2. Paste the title
The chip head is the key part of SMT placement machine. After picking up the components, it can automatically correct the position under the control of the calibration system, and accurately paste the components to the designated position.
3. X, Y positioning system
X, Y positioning system is the key mechanism of the placement machine, and also the main index to evaluate the accuracy of the placement machine, including X, y transmission structure and X, y servo system.
4. SMT feeder
In SMT placement machine, the feeder occupies a large number and position, and its function is to provide SMC / SMD chip components to the chip head according to the law and order, so as to pick up accurately and conveniently.
5. Sensors
At present, various sensors are installed in SMT Mounter, which can check the electrical performance of components, such as the eyes of SMT Mounter, and monitor the normal operation of the machine at all times. Generally speaking, the more sensors are used, the higher the intelligent level of SMT is.
6. Optical alignment system
The alignment of the mounter is to ensure that the suction nozzle is sucked in the center of the component, so that the center of the component is consistent with the center line of the spindle of the chip head.
7. SMT Mounter transmission mechanism and support platform
The transmission mechanism refers to the ultra-thin belt conveyor system placed on the track. Its main function is to send the PCB to the predetermined position, and then send SMA to the next process after the placement.
