It includes the whole process from theory to practice, such as automatic control theory, control system design, system simulation, on-site debugging, and reliable operation. And because of the wide application of microcomputers, SMT mounter machine automation control technology is more integrated with computer control technology, and it has become a very important core technology in mechatronics.
Take the SMT mounter machine as an example, because the mounting speed of components is affected by the size of the PCB, the types of components and feeders used, and so on. When selecting the control technology, various factors should be considered comprehensively, and the movement sequence and path of the placement head should be optimized to make the total travel time of the entire circuit board the shortest in order to achieve the most efficient purpose.
Due to the strict time requirements of SMT mounter machines and the miniaturization of IC pin spacing, the positioning of ICs on the PCB is under high-speed motion conditions (such as linear speed up to 100km/h, acceleration up to 5-6g), the positioning accuracy needs to be kept within 0.1mm, and at the same time, the placement force of the components also needs to be strictly controlled.
Therefore, in order to meet the index requirements of speed, acceleration, vibration, shock, and placement strength, SMT mounter machines need to establish a motion control model and develop an intelligent control strategy with the goal of achieving high precision, efficient shock absorption and high speed.
