具体实施方式
为了使本发明的目的、技术方案及优点更加清楚明白，下面结合附图及实施例对本发明作进一步详细说明。应当理解，此处所描述的具体实施例仅用以解释本发明，并不用于限定本发明。
一种用于皮革绘图的自动换笔机构，如图1-6所示，包括连接壳体1、致动器2、上盖体3、转动本体4和弹性机构5，连接壳体1与机械臂连接，通过控制机械臂，以控制换笔机构在皮革上绘图。连接壳体1内设置安装腔，转动本体4转动设置在安装腔内，并且转动本体的下端突出于连接壳体1，转动本体4绕其旋转中心等间距设置若干个用于安装绘画笔的安装孔41，安装孔41内设置弹性机构5，利用弹性机构5推动绘画笔向上移动使笔尖隐没于安装孔41内且上端突出于安装孔41，上盖体3与连接壳体1可拆卸连接，上盖体3的下表面向下凸起设置顶块31，且位置与安装孔41对应，顶块31两侧设置与上盖体3连接的引导部32，致动器2设置在上盖体3上，并且与转动本体4可拆卸连接，利用致动器2驱动转动本体4转动。假设安装孔41设置6个，即相邻两个安装孔41之间的间隔的角度为60°，通过顶块31将绘图笔9向下推，使得绘图笔9的笔尖突出与弹性机构5的下端；当需要换笔时，致动器2驱动转动本体4转动60°，当下的绘图笔9受到弹性机构5的回复力顺着引导部32向上移动，相邻绘图笔9受到引导部32的引导向下移动，同时受到弹性机构5使其始终紧贴于顶块31上。通过上述步骤以实现自动换笔。
在一实施例中，如图1-6所示，连接壳体1的侧壁上等间距设置至少三个光孔11，对应的，在上盖体3的侧壁上设置螺孔33，固定螺丝12穿过 光孔11与螺孔33螺纹配合。优选的，光孔11和螺孔33均设置四个，对应的，固定螺丝12也设置四个，通过四根固定螺丝，实现上盖体3与连接壳体1的可拆卸连接，只需要将上盖体3打开，即可对安装孔31内进行绘图笔9更换。同时保证上盖体3安装后与连接壳体1相对位置不变。
在一实施例中，如图1-6所示，弹性机构5包括调节壳体51、调节环52和调节弹簧53，调节弹簧53和调节环52设置在调节壳体51内，使得调节环52能够在调节壳体51内轴向移动，调节壳体51的一端设置容许绘图笔9的前端通过的通孔，调节环52设置用于安装绘图笔9的通孔；现有的绘图笔9通常具有阶梯结构，绘图笔9卡在调节环52上；将绘图笔9按下，调节弹簧53压缩，绘图笔9的前端从调节壳体51的通过突出。
在一实施例中，如图1-6所示，安装孔41的下端的内壁设置内螺纹，调节壳体51的外壁设置外螺纹，调节壳体51与安装孔41螺纹配合。通过上述结构，实现弹性机构5快速拆装。
在一实施例中，如图1-6所示，转动本体4的旋转中心设置方形凹孔42，致动器2的连接轴设置与凹孔42配合的凸块21。通过凹孔42和凸块21能够实现致动器2与转动本体4快速拆装，进而方便对绘图笔9进行更换。
在一实施例中，如图1-6所示，致动器2为伺服电机。
本发明在使用时，如图1-6所示，以6个安装孔41为例，将绘图笔9插入安装孔41内，并且卡于调节环52上，利用安装孔41作为绘图笔9的引导孔。而后盖上上盖体3，并且将致动器2与转动本体4连接，上盖体3通过固定螺丝与连接壳体1固定，完成绘图笔9的安装；当绘图笔9到达更换标准后，致动器2驱动转动本体4旋转60°后，实现绘图笔9的更换，并且保证绘图笔9位置不变。
以上仅为本发明的较佳实施例，并非用来限定本发明的实施范围；如果不脱离本发明的精神和范围，对本发明进行修改或者等同替换，均应涵盖在本发明权利要求的保护范围当中。
