From the aspects of system structure, control unit and upper software design, a complete set of highly intelligent high-speed mounter control system was designed and implemented, including 16 axis Z-axis linear motor based on 32-bit ARM processor plus 2 axis R-axis rotary servo motor mounter control unit, X、 Y gantry real-time interpolation motion control unit, IO control unit and PCB control unit. Combined with the real-time scheduling optimization algorithm of computer, a high-speed SMT mounting system with two arms and two mounting heads was designed and implemented. FDCAN communication mode, SMT head control unit based on linear motor and X、Y axis position control minimalist interpolation method were proposed to solve the key problems of SMT control system, such as rapid information interaction, accurate and fast positioning, high speed and high efficiency;the algorithm of solving position and angle deviation through visual processing, the algorithm of real-time path optimization through shortest path traversal, and the modular human-computer interface were discussed. The proposed system design method has been tested in practice and proved to be feasible and effective in the manufacturing, production and market application of the mounter.
