SMT machine is a kind of equipment used to achieve high precision, high speed, automatic components on the PCB circuit board, is the most critical and intelligent equipment in the entire SMT production line. The quality of a SMT machine is determined by the quality of the accessories and the intelligence and optimization of the software. So in the purchase of SMT machine, need to pay attention to what accessories?
1. SMT Feeder
The patch will pick up the components on the SMT Feeder at the designated location and then mount them. As one of the most important parts of the mount machine, Feeder has a significant impact on the production efficiency and precision of the mount machine. There are many ways to classify Feeder, belt type, pallet type, bulk material box type, tube type; Can also be divided into electric Feeder and pneumatic Feeder. The price of electric Feeder is higher than that of pneumatic Feeder, but it has higher stability and durability, and can be mounted 0201.
2. SMT suction nozzle
SMT nozzle is also one of the important parts of the Mounting machine, used to absorb and place components. Use vacuum adsorption to absorb, and then use high air pressure to mount the components. Different components require different suction nozzles. The suction nozzles come in different materials, sizes and shapes. During production, the deformation or damage of the suction nozzle will lead to the failure of the mounting head. Need good maintenance.
3. Lead screw, Guide rail, Driving motor
Lead screw, guide rail and drive motor are important accessories of the XY-axis movement mechanism of mounting machine. At present, the quality of domestic accessories is not as high as the quality of imported products. Imported parts with high efficiency, high precision, high rigidity, high durability, low noise characteristics. Lead screw and guide rail also need regular maintenance.
4. Visual system
The vision system of the mount machine determines the accuracy and stability in the mount process. The vision system of the mount machine generally consists of two types of cameras. The Mark camera is used to capture the system coordinates of the PCB board. Detect the deviation between the center of the camera’s shooting element and the center of the nozzle. The vision system of the mount machine ensures and corrects the mount accuracy through the precision camera, light source, image acquisition card and processing system. Therefore, high quality, high pixel cameras are necessary.
5. Industrial computer, vacuum generator, photoelectric sensor, cylinder, conveyor belt, etc.
Mounting machine also contains many other important accessories, such as the focus on adapting to different environments of high-performance industrial computers; Vacuum generator and solenoid valve with stable and reliable suction. In the purchase of the SMT machine, have a certain reference value.
