Method for controlling moving slide block on curved surface

Abstract

The invention relates to a method for controlling a moving slide block on a curved surface, relating to a slide block motion mechanism. The method provided by the invention is low in cost, is simple to operate and can be used for realizing accurate moving and positioning. The method comprises the following steps: firstly, setting an electromagnet array and a drive control circuit of the electromagnet array; then programming a control program, turning on a power supply to cause a singlechip to operate, and issuing a control instruction to all the electromagnets by the singlechip; and sequentially switching on / off all the electromagnets according to the set program, and sequentially sucking all the electromagnets with the moving slide block according to the switching sequence to cause the moving slide block to accurately move, stop and reset, thus realizing accurate control on the curved surface track of the moving slide block. Complex three-dimensional spatial curve motion control is changed into two-dimensional planar curve switching control; the traditional mode of motion of the slide block driven by a motor is broken through, and invisible motion of magnetic poles is utilized to control visible motion of the slide block; and the characteristic that the magnetic poles with same polarities repel each other but magnetic poles with opposite polarities attract each other can be utilized to realize accurate control on the static position of the slide block.
