为解决目前马赛克自动铺贴上料过程中采用的旧式分队机构的缺点,提出一种电磁铁驱动的新型机构.首先利用ANSYS Maxwell软件仿真分析了一对电磁铁之间的作用力,发现排斥力很小,于是在优化电磁铁结构后设计出仅利用吸引力实现滑台之间分开或合拢的结构,并分析了滑台运动时的受力情况.然后分析了运动流程,并仿真分析了不同作用间隙时电磁力的大小,结果显示能够满足驱动需求.最后通过实验简单测试了实际驱动力以及响应速度,结果显示其能够满足快速运动的需求,而且发热量低,实用性很好.%The shortcomings of an old line-separate mechanism used in the process of mosaic automatic loading were analyzed, and a novel mechanism driven by electromagnets is proposed to solve this problem. Firstly, the preliminary structure of electromagnets was designed then the magnetic field simulated by using ANSYS Maxwell. It is found that the repulsive effect between the electromagnets is not obvious. Then the mechanism was design, using a special type of electromagnet as driven unit which only applies attraction effect to achieve gather and separate motion of the slider group. Then the process of movement and the electromagnetic force have been analyzed, in the case of low DC voltage, the driven force is enough to achieve quick response requirement. Finally, the experiment results indicate that this slider group can actually be used for industrial application.
