Abstract: In traditional multi-wire saw have function of manual winding only and the limitations of LED base material uneven force , the rocking mechanism is proposed to substitute for the original fixed structure, automatic winding function is increased, the quality and efficiency of slice and utilization rate of the diamond wire are improved. The mechanical structure and working principle are analysed after machine structure is improved. Two difficult problems which are automatic winding and multi-motor high-speed synchronization are mainly studied. Combining the advantages of fuzzy control and iterative learning control, a fuzzy iterative learning control strategy of Multi-wire saw with rocking mechanism is given.This strategy overcomes the steady-state error of single fuzzy control and get better control effect. The automatic winding error control scheme is designed, when diamond wire do not embed into the slot and around the slot wall, the control scheme can act quickly to make the diamond wire into the slot. Experimental results show that the system automatic winding performs fast speed, high precision and synchronous control performance is good.
