参照图1，示出了本公开的一种预制体的结构示意图，如图1所示，预制体100包括回转面11，与回转面11垂直的顶面13以及连接回转面11和顶面13的圆弧面12，预制体100由多层炭纤维布料编织而成，在编织过程中需要将碳纤布料逐层包裹在预制体100上，每包裹一层碳纤布料需要对预制体100的回转面11、顶面13和圆弧面12进行一遍针刺，以使预制体100密实。
参照图2，示出了本公开的一种针刺装置工作状态的结构示意图一，如图2所示，本公开实施例中的针刺装置具体可以包括：针刺组件200，支架300、基座400以及承载框架500；其中，基座400可以设置于承载框架500内，基座400可以用于承载预制体100；支架300可以连接于承载框架500，且与基座400及预制体100相对；针刺组件200可以滑动连接于支架300，且可以沿导轨31滑动，对预制体100进行针刺作业。
本公开实施例中，针刺组件200滑动连接于支架300，可以调整针刺组件200在支架300上的位置，基座400设置在承载框架500内，基座400又用于承载预制体100，可以调整预制体100与针刺组件200相对的位置，进而调整针刺组件200对预制体100进行针刺作业的作业区域，使得针刺组件200可以对预制体100的圆弧面12进行较为全面的针刺作业，且针刺的深度和密度较为均匀，可以避免预制体100在沉积过程中出现变形和分层的现象，提高预制体100的加工质量，再者，针刺组件200可以自动进行针刺作业，速度较快，加工效率较高。
可选地，支架300上可以设置有导轨31，导轨31可以包括至少一个圆弧段，在实际应用中，导轨31的至少一个圆弧段可以与预制体100的圆弧面12对应设置，使得针刺组件200在导轨31的圆弧段处滑动的过程中，针刺组件200距离预制体100的圆弧面12的距离可以保持不变，这样，在针刺组件200对预制体100的圆弧面12进行针刺作业的情况下，可以提高针刺组件200对预制体100的圆弧面12针刺的均匀度。
具体地，导轨31还可以与预制体100的顶面13的形状适配，使得针刺组件200对预制体100的顶面13针刺的深度和密度较为均匀。
在实际应用中，可以手动调整针刺组件200在导轨31上位置，也可以在所述针刺装置上设置按钮，通过点击按钮实现自动调整针刺组件200在导轨31上位置。

具体的，针刺组件200用于对预制体100进行针刺作业的情况下，第一驱动机构21可以驱动针刺头24运动，使得刺针25可以匀速对预制体100进行针刺作业，使得刺针25刺入预制体100的深度和密度较为均匀，这样，可以避免预制体100在沉积过程中由于针刺密度不均匀出现变形和分层的现 象。
在实际应用中，第一驱动机构21可以包括第一电机211和往复机构212，往复件212又可以包括凸轮和连杆，具体的，第一电机211可以与所述凸轮连接，第一电机211可以用于驱动所述凸轮运动，所述凸轮可以与所述连杆连接，所述凸轮用于带动所述连杆往复运动，所述连杆与针刺头24连接，使得针刺头24可以对预制体100进行针刺加工。
可选地，针刺头24上可以设有弹性件，刺针25可以通过所述弹性件连接于针刺头24上，由于所述弹性件可以用于调节刺针25的力度，使得刺针25对预制体100针刺的深度较为统一。具体地，所述弹性件可以为可调弹簧。
可选地，驱动组件2还可以包括第二驱动机构22，第二驱动机构22可以滑动连接于支架300上的导轨31；第二驱动机构22可以用于带动针刺头24沿导轨31滑动。在实际应用中，第二驱动机构22可以驱动针刺头24沿导轨31滑动，这样，在针刺组件200对预制体100的圆弧面12进行针刺的情况下，可以调节针刺头24与预制体100的圆弧面12对齐的位置，使得刺针25可以较为全面的对圆弧面12进行针刺作业。

可选地，针刺头24上还可以设有夹紧机构23；夹紧机构23可以包括至少一组相对设置的夹紧轮231，每组夹紧轮231夹持于导轨31，且可沿导轨31滑动。本公开实施例中，至少一组相对设置的夹紧轮231可以夹持于导轨31，这样，在针刺头24沿导轨31滑动的过程中，针刺头24贴合导轨31滑动，可以避免针刺头24从导轨31上脱落，影响针刺头24对预制体100针刺的质量。
结合图2和图3所示，齿轮222可以作为夹紧轮231使用，具体地，如图2和图3所示，夹紧机构23可以设置为两组夹紧轮231，每组夹紧轮231 可以包括两个夹紧轮231和两个齿轮222组成，且夹紧轮231与齿轮222相对设置，在针刺头24沿导轨31滑动的过程中，夹紧轮231可以与齿轮222配合，夹紧导轨31，提供针刺头24在导轨31上的附着力，避免针刺头24从导轨31上脱落，影响针刺头24对预制体100针刺的质量，同时夹紧轮231与齿轮222的啮合还可以带动针刺组件300在导轨31上运动。本公开给出了一种如图2和3所示的夹紧机构23的结构，具体可参考图2和图3设置，本公开不做具体限定。

在实际应用中，在针刺组件200对预制体100的圆弧面12进行针刺作业的情况下，针刺组件200做往复运动对预制体100进行针刺作业，旋转机构42可以带动安装柱41旋转，从而带动预制体100围绕预制体100的轴线旋转，使得针刺组件200可以对圆弧面12的各个区域进行针刺加工，对圆弧面12针刺的更全面。
具体地，旋转机构42可以包括旋转件422和第三电机421，第三电机421可以与旋转件422连接，用于驱动旋转件422旋转；旋转件422可以与安装柱41连接，用于带动安装柱41旋转。

在实际应用中，基座400上设有升降机构43和移动机构44，在预制体100安装至基座400上的情况下，可以通过升降机构43调整预制体100与针刺组件200在垂直方向上的距离，可以通过移动机构44调整预制体100与针刺组件200在水平方向上的距离，通过升降机构43和移动机构44的配合使用实现对预制体100与针刺组件200之间距离的调整，使得针刺组件200 可以对不同尺寸的预制体100进行针刺加工，提高针刺组件200的实用性。
具体地，升降机构43可以包括升降组件432和第四电机431，第四电机431可以与升降组件432连接，用于驱动升降组件432沿竖直方向运动；升降组件432可以与安装柱41连接，用于带动安装柱41沿竖直方向运动，从而带动预制体100沿竖直方向运动。升降组件432还可以由4组同型号的涡轮、蜗杆组成，且4组涡轮、蜗杆同步运行，以带动预制体100平稳地升降，升降组件432还可以由其他结构组成，本公开不做具体限定。

而且，由于可以调整针刺组件200与预制体100的对应位置，在拆卸预制体100的情况下，可以将支架300滑动至承载框架500上远离预制体100的位置，避免支架300与预制体100冲突。
具体地，如图2所示，支架300可以沿承载框架500滑动，将支架300沿着承载框架500滑动的方向作为X轴方向，从而可以调整针刺组件200与预制体100在X轴方向上的距离；移动机构44可以带动预制体100沿水平方向在Y轴方向上运动，从而可以调整针刺组件200与预制体100在Y轴方向上的距离；升降机构43可以带动预制体100沿竖直方向在Z轴方向上运动，从而可以调整针刺组件200与预制体100在Z轴方向上的距离，由 于X轴、Y轴、Z轴互相垂直，从而可以灵活调整针刺组件200与预制体100之间的距离。
