1, SMT placement machine frame:

　　In the structure of the SMT placement machine, the frame is the foundation of the machine, and all the transmission, positioning, and transmission organizations are firmly fixed on it. At present, various types of racks can be divided into integral casting type and steel plate welding type. However, because most types of placement machines and various feeders are also placed on them, the racks should be satisfactory. Mechanical strength and rigidity.

2. SMT placement machine transfer organization and support platform: the transfer organization refers to the ultra-thin belt conveyor system placed on the track. The primary function is to send the PCB that needs to be patched to the predetermined position. After the patch is completed Send the SMA to the next process.

　　3. X, Y positioning system: The X, Y positioning system is not only the key organization of the placement machine, but also the primary goal of evaluating the accuracy of the placement machine. It includes the X, Y transmission structure and the X, Y servo system.

　　4. Optical centering system: The centering of the placement machine means that the placement machine must ensure that the suction nozzle is sucked in the center of the component when picking up the component, so that the center of the component is consistent with the center line of the spindle of the placement head.

　　5. Mounting head: The mounting head is the key component of the SMT placement machine. After it picks up the components, it can automatically calibrate the position under the control of the proofreading system, and accurately place the components in the specified position.

　　6. ​​SMT feeder: In the SMT placement machine, the feeder occupies a large number and orientation, and the function is to provide the chip components SMC/SMD to the placement head in accordance with a predetermined rule and order for accurate and convenient picking.

　　7. Sensors: Now, SMT placement machines are equipped with a variety of sensors, they can check the components and electrical functions, they are like the eyes of the placement machine, time monitors the normal operation of the machine. The most common ones are pressure sensors, negative pressure sensors and orientation sensors. Generally speaking, the more sensors are used, the higher the level of intelligence of the placement machine.
