Description

超声增材制造装置及方法 技术领域
本发明涉及增材制造技术领域，尤其涉及超声增材制造装置及方法。
背景技术
增材制造技术，又称3D打印，是快速成型技术的一种，融合了计算机辅助设计、材料加工与成型技术、以数字模型文件为基础，通过软件与数控系统将专用的金属材料、非金属材料以及医用生物材料，按照挤压、烧结、熔融、光固化、喷射等方式逐层堆积，制造出实体物品。因其成型速度快、成型工艺简单和节约原材料等特点，增材制造技术在各领域被广泛研究及应用。
目前用于树脂材料的增材制造技术包括：SLA、SLS、PolyJet、DLP、FDM等，这些技术存在一些问题：
(1)SLA、SLS、PolyJet等精度较高的设备成本高，需要使用激光器等价格高昂的配件，或者对于喷头的加工要求高，而且设备的存放和使用环境要求高；
(2)FDM的精度低，加热源外露，容易造成安全隐患。
在增材制造中，常使用超声波作为辅助手段来检测或调整产品的内在结构，其主要的固化手段还是光固化和热固化，可看作是在常规的3D打印设备上添加产生超声波的设备。而目前存在着可通过超声波固化的材料，如专利号为CN200580014019.0的专利文件《超声固化牙齿填充材料》中提及通过采用超声或者通过化学引发物来引发填料成分的马丁转变，申请号为CN90105864.5的专利申请一种超声波固化牙体修复树脂也是通过超声波来固化树脂，在期刊《石油工程建设》中曾刊登《超声波加速环氧树脂固化》一文，从上述材料可见将超声波应用于增材制造的固化手段是可行的，但是目前的增材制造技术和相应的设备并不适合超声增材制造(即超声打印)。
为解决上述问题，本发明提出一种成本低、安全环保、高效精准的超声增材制造装置及方法。
发明内容
为了解决目前增材制造领域内存在的加工要求高、成本高的技术问题，本发明提供了这样一种超声增材制造设备，包括：
支架，是给整个设备提供支撑，承载各部分零件；
材料缸，固定在支架上，所述材料缸内部设置有竖向上下运动的打印基板；
超声打印头，位于材料缸上方，且水平面上做横向及纵向的二维运动，所述超声打印头包括自上而下设置的固定部、换能器和超声波导向装置，所述超声波导向装置的底端为圆锥形，中心设有一通孔，即超声波传导孔，通孔底部倒圆角，可控制超声波前进方向与范围，换能器控制超声波的声速锥面直径，该声速锥面直径为超声打印可执行的单道线宽，在打印开始前根据单道线宽来选择适合的换能器；

进一步地，二维运动模组安装于支架的顶层，所述二维运动模组包括横向运动模组和纵向运动模组，所述纵向运动模组可采用丝杆传动结构或传动带传动结构，所述横向运动模组可采用丝杆传动结构或齿轮传动结构。
进一步地，竖向运动模组固定在支架的底座和顶层之间，所述纵向运动模组采用传动带传动结构，包括左电机、右电机、传动杆和传动带，左电机和右电机分别设置在支架两侧棱上，传动杆上方的两端与支架顶层的棱的导轨滑动连接，传动杆下方的两端均设置有第一导轮，在支架另外两侧棱上分别设置有第二导轮，传动带将左电机、第一导轮、第二导轮和右电机连接为一个整体，左电机和右电机做相反转向的运动，通过传动带驱使传动杆在支架的顶层做纵向运动，当左电机输出端逆时针转动，右电机顺时针转动，此时位于外侧的传动带均朝向左电机和右电机运动，内侧的传动带均远离左电机和右电机运动，由于传动带总长度不变，因此在第一导轮和第二导轮的作用下，传动杆沿着支架顶层的棱的导轨滑动远离左电机和右电机，同理，左电机输出端顺时针转动，右电机逆时针转动，传动杆沿着支架顶层的棱的导轨滑动靠近左电机和右电机。
横向运动模组采用丝杆传动的结构，包括基座、横轴电机和与横轴电机连接的滚珠丝杆，所述基座与超声打印头的固定部连接，传动杆上方设置导轨，横轴电机的输出端与丝杆的螺杆连接,丝杆的传动杆通过螺母与基座连接，横轴电机输出端的转动转换为超声打印头沿着传动杆做横向线性运动，横向运动模组和纵向运动模组共同作用下，超声打印头可运动至横向(X轴)和纵向(Y轴)的任一位置。
进一步地，所述竖向运动模块包括竖轴电机、滚珠丝杆、辅助杆和滑块，竖轴电机安装于支架顶层的一条棱上，滚珠丝杆的一端与竖轴电机的输出端连接，另一端与支架底座的连接，辅助杆位于支架的顶层和支架底座之间位于滚珠丝杆的螺杆的两侧，滚珠丝杆的螺杆由竖轴电机驱动，滑块与滚珠丝杆的螺母连接，打印基板的一端与滑块连接且套入辅助 杆，螺杆的旋转运动转化为滑块的线性运动从而带动打印基板线性运动，因此竖轴电机运行时驱使打印基板在竖向做上下运动。
进一步地，打印基板为阶梯式结构，打印基板上端为连接部且与竖向运动模块连接，打印基板下方为工作平台，连接部和工作平台通过连接杆连接，所述工作平台内设置有多个通孔，在工作平台浸入材料缸内时，在超声打印过程中，液体打印材料可持续从通孔流入工作平台内，使得工作平台内的液体打印材料始终均匀分布。
进一步地，所述材料缸通过抽液泵与外部的储液缸连通，所述材料缸的缸口边缘设置有红外探测器，所述红外探测器通过控制模块与抽液泵电连接，红外探测器的朝向与液面垂直，当材料缸内的液面下降时，红外探测器将液面下降的信息反馈抽液泵，抽液泵启动并将储液缸内的材料液体抽送至材料缸内。
一种超声增材制造方法，在所述的超声增材制造装置中进行超声打印，包括以下步骤：
a.分析目标模型参数并分层，确定目标模型每层打印的参数；
