[Abstract]:PCB milling cutter is one of the important consumables in PCB process. With the rapid development of PCB industry, the demand for PCB milling cutter increases, and the automatic slotting equipment has a good market prospect. And occupies the domestic main market, but its price is high, the technology is confidential, therefore research and development PCB milling cutter automatic slotting equipment with independent intellectual property has the urgent application demand. The key technologies of motion control system, including zero back algorithm, velocity planning, interpolation algorithm and reverse gap compensation algorithm, are discussed in detail. Firstly, the mathematical model of spiral groove of PCB milling cutter is discussed, and the equation of cylindrical spiral groove of PCB milling cutter is obtained. At the same time, on the basis of requirement analysis, the paper puts forward the related requirements for the design of automatic slotting equipment system, and plans the hardware and software design scheme of the system, including the mechanical part and the motion control part. Secondly, the paper focuses on the research of motion control system of automatic slotted equipment, introduces the commonly used motion control algorithm, velocity planning algorithm and interpolation algorithm, aiming at the specific mechanical structure and control requirements of the equipment. The corresponding motion control algorithm suitable for the equipment is proposed. The experimental results show that the repetitive precision of the proposed control algorithm is 1.3 渭 m, which can meet the processing requirements. In addition, considering the semi-closed loop control structure of the equipment, The reverse gap compensation algorithm based on acceleration and deceleration control is studied and simulated in vs. The results show that the algorithm can realize the design intention. Thirdly, according to the demand of PCB milling cutter automatic slotted equipment, the PLC program is written to realize the automatic running logic of the equipment, and the UI interface design of the system is completed under the Visual Studio2008 platform. Finally, after the equipment assembly is finished, the whole equipment is debugged, the communication experiment is carried out, and the machining precision and efficiency of the equipment are measured. The experimental results show that the relevant methods and implementation techniques are effective and feasible. It has important application value for improving the machining quality and efficiency of PCB milling cutter.
