Abstract

The invention discloses a motion control method and device based on an electronic cam curve, which can determine the motion position of a driving shaft and determine the target motion position of a corresponding driven shaft based on an electronic cam position corresponding curve, and the electronic cam position corresponding curve comprises an asynchronous stage curve. The asynchronous stage curve at least comprises a first part of sub-stage curve and/or a second part of sub-stage curve, and the first part of sub-stage curve can be formed by sequentially connecting a first variable deceleration sub-stage curve, a constant deceleration sub-stage curve and a first variable acceleration sub-stage curve; the second part sub-stage curve is formed by sequentially connecting a second variable acceleration sub-stage curve, a constant acceleration sub-stage curve and a second variable deceleration sub-stage curve, and the driven shaft is controlled to move to the target movement position. The electronic cam position corresponding curve provided by the invention can effectively enrich electronic cam curve styles, so that motion control functions required by more motion control scenes can be effectively realized.

Description

technical field [0001] The invention relates to the technical field of motion control, in particular to a motion control method and device based on an electronic cam curve. Background technique [0002] With the development of science and technology, motion control technology continues to improve. [0003] A mechanical cam is a physical mechanism that enables the driving shaft and the driven shaft to meet a specific positional relationship during motion. It can be widely used in motion control fields such as chasing shears, flying shears, and labeling. Due to the difficulty in design and manufacture of mechanical cams, the difficulty of manufacturing precision to meet the requirements of motion control, and the ease of wear during motion, mechanical cams are gradually replaced by electronic cams. [0004] The electronic cam is a control system that can achieve a specific positional relationship between the driving shaft and the driven shaft by generating an electronic cam c...
