摘要:为了保证喷码检品机直线电机的定子与动子之间需要的0.7mm的缝隙,提高喷码定位装置的喷墨精确性,保证喷码位置误差在0.1mm以内,利用SolidWorks建立喷码检品机的三维模型后导入ANSYS软件对喷码检品机设备的定子固定板进行机械结构的静力学仿真,因为定子固定板变形量较大,拟定了三种不同的加强筋板布置方式来增大该板的强度,通过有限元分析的数据发现采用横向和纵向相结合的加强筋布置方式可以使定子固定板的形变量达到最低,形变量为0.089mm。

Abstract: In order to ensure the required 0.7mm gap between the stator and the Mover of the linear motor of the code-spraying inspection machine, improve the inkjet accuracy of the code-spraying positioning device and ensure that the error of the code-spraying position is within 0.1mm, a three-dimensional model of the code-spraying inspection machine is established by SolidWorks, and the static simulation of the mechanical structure of the stator fixing plate of the code-spraying inspection machine is carried out by ANSYS software, because the deformation of the stator fixing plate is large. Three different reinforcement plate arrangements are proposed to increase the strength of the plate. Through the data of finite element analysis, it is found that the transverse and longitudinal reinforcement arrangement can minimize the deformation of the stator fixed plate, which is 0.089 mm.

我国经济迅速发展,生活中商品也逐渐多样化,产品的包装也各式各样,一些不良商家为了盲目的追求利益最大化,对价格较高的商品进行仿制,这就导致市场上存在大量假冒伪劣商品的现象,尤其是在生活用品方面居多。为了避免假冒伪劣商品的出现损坏公司的声誉、侵害消费者的权益,烟酒包装等厂家对二维码喷码精度提出了更高的要求,要求喷码位置误差在0.1mm以内,然而由于振动、定位精度、喷码装置受力变形等因素的影响,现在的喷码装置精度只能达到0.3mm左右,达不到厂家要求的高精度[1-4]。市场上迫切需要一套高精度的喷码定位装置,此外喷码装置的高精度研究不仅可以提高喷码、上光等印刷设备的喷印精度,也会给其他行业高精度定位的研究提供思路[5-7]。
