The invention relates to an embroidery machine tabouret position closed-loop control device for embroidery machine control box position embroidery, embroidery machine comprises a fixed frame of the embroidery fabric, embroidery frame drive unit X axis and Y axis drive unit, a drive control unit, conveying signal to X axis displacement embroidery frame drive unit and the drive shaft Y the unit, which is characterized in that the grating displacement sensor optical head is fixed on the frame should be X / Y axis two axis direction, move together with the frame, grating displacement sensor position signal is converted into digital signal, through the cable is transmitted to the DSP data sampling interface, through the software compensation algorithm, and then corrected shift the frame displacement, and the driving control unit will be modified X / Y signal axis displacement shift frame transmission to X axis embroidery frame drive unit and a Y axis drive unit. The invention achieves closed-loop software frame shift control, to make up for the current lack of open loop control in frame shift, the actual effect is to ensure that the frame shift accuracy, improve the quality of embroidery, overcomes the deviation on mechanical assembly.
【技术实现步骤摘要】
【技术保护点】
刺绣机绣框位置闭环控制装置，用于刺绣机控制刺绣框位置，刺绣机包括：将织物固定的刺绣框，刺绣框的Ｘ轴驱动单元和Ｙ轴驱动单元，驱动控制单元，将刺绣框位移的信号输送给Ｘ轴驱动单元和Ｙ轴驱动单元，其特征在于：光栅线位移传感器的光感应头固定在绣框的Ｘ轴／Ｙ轴两个方向上，随着绣框一起移动，光栅线位移传感器将位置信号转换成数字信号后，通过电缆线传送到ＤＳＰ的数据采样接口，通过软件的补偿算法，再修正移框位移，并通过驱动控制单元将修正移框位移的Ｘ轴／Ｙ信号输送到刺绣框的Ｘ轴驱动单元和Ｙ轴驱动单元。
