LED Chip Sorting System Design Based on ACS Motion Control

为了提高LED晶片分选机的分选速度和精度,设计了基于IPC+ACS运动控制的LED晶片分选系统;分析了晶片分选过程直线电机定位、直驱电机旋转以及音圈电机拾取三部分的时序,并结合电机性能分别规划了3类电机的定位时间;以直驱电机为例分析了在SPiiPlus MMI软件环境中调试电机电流环、速度环和位置环以及频域稳定性的过程,并最终给出3类电机的定位时间和定位误差;设计了吸嘴和顶针接触式剥离拾取晶片的方案,利用ACSPL+语言编写拾取动作的程序,并在速度环和位置环曲线中加以验证;在ZKMY-P10型号的分选机分选平台进行了连续分选测试,实验结果表明,分选机的X/Y轴定位精度为±0.5 mil,晶片分选的平均速度为125 ms/片。

In order to improve the sorting speed and accuracy of the LED chip sorting machine,an LED chip sorting system based on IPC+ACS motion control is designed.The positioning of the linear motor,the rotation of the direct drive motor and the voice coil motor picks up the timing of the three parts,and combines the motor performance to plan the positioning time of the three types of motors.Taking the direct drive motor as an example,the debugging of the motor current loop,speed loop,position loop and frequency in the SPiiPlus MMI software environment is given.The process of domain stability verification,and finally the debugging results of the three types of motors are given.A plan for picking up the chip by contact peeling of the suction nozzle and thimble is designed,and the picking action program is written in ACSPL+language and verified on the speed and position curve.The continuous sorting test was carried out on the sorting platform of the ZKMY-P10 type sorter.The experimental results show that the X/Y axis positioning accuracy of the sorter is±0.5 mil,and the average speed of chip sorting is 125ms/piece.
