Electromechanical Co-simulation And Experimental Verification For Swing Arm Of High-Speed LED Chip Sorting Machine

In order to improve the efficiency of chip sorting, the paper studies on swing arm rotation system of high-speed LED sorting machine and focus on the optimization design and structure simulation of the swing arm, the analysis and modeling of servo drive system, electromechanical co-modeling of multi-rigid-body and rigid-flexible coupled body, the design of command inputs, co-simulation, the realization of swing arm rotation experiment platform, experimental verification. The main contents are:First, through the introduction of the whole structure,function and chip sorting process, the role of rotating system and the influence factors of chip sorting efficiency were pointed out. The implementation of swing arm rotating system and three new plans were analyzed. The servo drive system of direct driving scheme was introduced for servo drive modeling.And, based on the model and servo parameters of swing arm rotation system, the paper established its servo drive model on MATLAB/SIMULINK and adjusted servo parameters by simulation. According to actual load, a virtual load model is created for verifying the accuracy of servo drive model by load calibration.Then, the dynamic models of multi-rigid-body and rigid-flexible coupled body were built by ADAMS, ANSYS and Pro/E. The dynamic model and servo drive model are connected to realize co-simulation model which is used for debugging servo parameters. The design of co-simulation command inputs based on the pulse speed curve of EMAC and chip sorting cycle was introduced to co-simulation using MATLAB/SIMIN.At last, the swing arm experiment platform was built by designing, purchasing and assembling mechanical components, integrating electromechanical system and debugging control parameters. By preparing arm back to zero and rotation procedures and doing swing arm experiments of movement and location, control parameters were optimized and the new swing arm structure and co-simulation were verified. The results of experiment stated that experiment platform for direct drive improved the efficiency of the first generation sorting machine, but did not completely meet the demands of swing arm, the reasons for that were pointed out.
