Description

3D笔
技术领域
本发明涉及可容易选择多种颜色的料丝来使用的新的结构的3D笔。
背景技术
最近,开发用户可自由制造三维物体的3D笔,并广泛使用。
上述3D笔将呈长长的棒状的热固性合成树脂材质的料丝进行加热来排出,如图1及图2所示,包括:外壳10,向前后方向延伸,在前后侧形成有使料丝1贯通的供给孔11和排出孔12;供给单元20,设置于上述外壳10的内部,向排出孔12侧供给向上述供给孔11供给的料丝1;以及加热机构30,加热向上述排出孔12排出的料丝1。
此时,在上述外壳10的外侧面设有用于由用户操作来控制加热机构30和供给单元20的工作的输入机构41、42、43。
上述输入机构41、42、43利用可由用户用手按压来输入信号的开关,包括:电源开关41,用于接通(ON)上述加热机构30;前进开关42,用于使上述料丝1向排出孔12的前方突出;及后退开关43,用于使料丝1后退。
因此,在用户通过上述供给孔11向上述供给单元20被供给的料丝1的状态下,操作上述输入机构41、42、43使加热机构30接通,当操作输入机构41、42、43使供给单元20驱动时,通过供给单元20向排出孔12侧供给料丝1,被上述加热机构30加热之后,通过上述排出孔12向外壳10的外侧排出,当用户调节3D笔的前端部的位置时,向排出孔12排出的料丝1被冷却并变硬,制造用户所需的形态的物体。
另一方面,利用这种3D笔制成的物体的颜色根据料丝1的颜色而确定。
因此,若想制造具有多种颜色的物体,需要根据将制造的物体的颜色由用户更换料丝1,因而存在使用非常麻烦的问题。
因此,需要可解决这种问题的新的方法。

具体为,上述导块21由相互层叠的下部板21d和上部板21e构成,上述供给通道21a由三个构成,形成于上述下部板21d和上部板21e之间,以便于相互侧向隔开。
此时,上述导块21形成有连接通道21b,上述连接通道21b以位于上述供给通道21a的前方的方式向前后方向延伸,上述连接通道21b的前端部与上述排出孔12相连接,上述供给通道21a的前端部与上述连接通道21b的后端部相连接。
并且,上述供给孔11由三个构成,通过连接管15分别与上述供给通道21a的后端部相连接。
因此,当通过上述供给孔11将三种不同颜色的料丝1插入于供给通道21a之后,向前方推动一种料丝1时,料丝1通过上述连接通道21b向排出孔12的前方排出。
并且,在上述导块21的内部形成有以可旋转的方式结合上述移送辊22和支撑辊23的空间部21c。
上述空间部21c的一侧与上述供给通道21a相连通。
上述移送辊22以可利用向上下方向延伸的旋转轴22a转动的方式与上述导块21的空间部21c内部相结合,在周边面形成有齿轮齿,坚固地紧贴于插入于上述供给通道21a的料丝1的一侧面。
上述旋转轴22a的上端向上述导块21的上侧延伸。
此时,上述移送辊22分别连接有从动齿轮22b。
上述从动齿轮22b利用以位于上述导块21的上侧的方式与上述旋转轴22a的上端固定结合的锥齿轮,当使从动齿轮22b旋转时,上述旋转轴22a和移送辊22旋转。
上述支撑辊23以可利用向上下方向延伸的旋转轴23a旋转的方式与上述空间部21c的内部相结合,通过支撑在上述料丝1的周边面中与上述移送辊22的周边面紧贴的面相反的一侧的面,使上述移送辊22坚固地紧贴于料丝1的周边面。
上述驱动马达24以可侧向转动的方式与上述导块21的上部面相结合,向后方延伸的驱动轴设有选择性地与上述从动齿轮22b相结合的驱动齿轮24a。
上述驱动齿轮24a利用与上述从动齿轮22b相对应的锥齿轮。
因此,如图13所示,当使上述驱动马达24侧向转动时,上述驱动齿轮24a选择性地与上述从动齿轮22b中的一个相结合,驱动马达24和上述移送辊22中的一个选择性地连接,可使驱动马达24驱动来使上述移送辊22正反向旋转。
此时,在上述外壳10的上部面形成有与设置于上述驱动马达24的转动轴24b相对应的贯通孔13。
上述调节杆25呈直径大的圆板形态,在下侧面中央部设有通过上述贯通孔13插入于外壳10的内部而与上述转动轴24b的上端相结合的延伸管25a。
此时,如图5及图8所示,在上述转动轴24b的上端形成有四角棒形态的延伸部24c,上述延伸管25a形成有使上述延伸部24c插入的四角形的结合孔25b,上述延伸管25a以可向转动轴24b的长度方向滑动且不侧向转动的方式与上述延伸部24c的外侧相结合。
上述转动部件26从上述延伸管25a的一侧侧向延伸。
此时,在上述外壳10的内侧面形成有以上述贯通孔13为中心的多个凹槽14,在上述转动部件26形成有选择性地插入结合于上述凹槽14的突出部26a。
如图8所示,上述凹槽14形成为三个,以与上述移送辊22相对应,且以上述贯通孔13为中心侧向隔开,以便于与以上述转动轴24b为中心的移送辊22的角度相对应。
上述弹性部件27使用压缩螺旋弹簧,上述压缩螺旋弹簧以向上下方向延伸的方式与上述转动轴24b的外侧相结合,上述压缩螺旋弹簧的下端被上述驱动马达24的上部面支撑,上述压缩螺旋弹簧的上端被上述延伸管25a的下侧面支撑,向上侧加压调节杆25和转动部件26。
因此,平时,利用上述弹性部件27向上侧加压上述调节杆25和转动部件26,以使上述突出部26a插入于凹槽14,固定调节杆25和驱动马达24防止这些侧向旋转。
并且,如图11所示,当用户向下侧加压上述调节杆25时,调节杆25和转动部件26下降,解除上述突出部26a和凹槽14的结合,由此,用户可使调节杆25旋转来使上述驱动马达24侧向转动。
并且,当在用户使驱动马达24转动,驱动马达24的驱动齿轮24a与设置于其他移送辊22的从动齿轮22b相结合的状态下释放上述调节杆25时,调节杆25和转动部件26被弹性部件27上升,上述突出部26a插入于其他凹槽14而结合,从而以防止驱动马达24转动的方式固定。
上述加压检测机构28以位于上述调节杆25的下侧的方式设置于上述外壳10的上部面,利用当上述调节杆25下降时,检测这一情况来输出信号的限位开关。
上述固定机构29以朝向上述延伸管25a的方式设置于上述外壳10,根据上述控制机构50的控制信号工作,以防止上述调节杆25转动的方式固定。
为此,如图5及图8所示,在上述延伸管25a的周边面形成有与上述凹槽14的角度对等地隔开的三个固定槽25c,上述固定机构29设有选择性地插入固定于上述固定槽25c的固定条29a。
因此,当上述固定条29a插入于上述固定槽25c时,上述调节杆25以防止旋转的方式固定,当利用控制机构50驱动固定机构29时,上述固定条29a后退并从固定槽25c脱离,可使调节杆25旋转。
此时,上述固定槽25c向上下方向长长地延伸,在上述固定条29a的前端部与固定槽25c相结合的状态下,可使上述调节杆25和延伸管25a升降。
上述控制机构50接收上述输入机构41、42、43和加压检测机构28的信号,控制上述加热机构30和供给单元20的工作。
详细说明这种3D笔的作用如下。
首先,用户将颜色不同的三个料丝1插入于上述供给孔11,如图3所示,以使料丝1的前端部相比于上述供给单元20的移送辊22更向前方突出,当在操作上述电源开关41来使上述加热机构30接通的状态下操作上述前进开关42时,上述控制机构50使上述驱动马达24驱动来使上述移送辊22旋转,如图10所示,向前方推动三个料丝1中的一种,从而在料丝1被加热机构30加热之后,通过上述排出孔12向外壳的前方排出。
并且,当用户使用不同颜色的料丝1制造物体时,如图11所示,向下侧按压上述调节杆25来解除上述突出部26a和凹槽14的结合。
此时,上述控制机构50接收上述加压检测机构28的信号,确认这一情况,如图12所示,使上述驱动马达24反向驱动规定时间来使插入于上述排出孔12的料丝1向上述供给通道21a后退。
与此同时,上述调节杆25维持上述固定条29a与上述固定槽25c相结合的状态,以利用上述固定机构29防止转动。
并且,当上述料丝1向供给通道21a后退时,上述控制机构50控制上述固定机构29来使固定条29a后退,可使调节杆25转动。
并且,当用户使上述调节杆25向一侧转动,如图13所示,使上述驱动齿轮24a连接于与其他移送辊22相连接的从动齿轮22b之后,放开按压调节杆25的手时,上述调节杆25和转动部件26利用上述弹性部件27上升,由此,上述突出部26a与上述凹槽14相结合。
此时,上述控制机构50接收上述加压检测机构28的信号,确认这一情况,控制上述固定机构29来使固定条29a前端部与上述固定槽25c插入结合。
并且,当用户操作上述前进开关42时,上述控制机构50使上述驱动马达24驱动以向前方移送不同颜色的料丝1,被上述加热机构30加热之后,通过上述排出孔12向前排出。
对于如此构成的3D笔而言,用户使调节杆25侧向转动来使驱动马达24与不同的移送辊22相连接,从而可选择性地向前方移送不同的多个料丝1来排出。
因此,具有结构非常简单且可容易选择多种颜色的料丝1来制造多种颜色的物体的优点。
在本实施例中,例示上述导块21由相互层叠的下部板21d和上部板21e构成,上述供给通道21a由三个构成,形成于上述下部板21d和上部板21e之间,以便于相互侧向隔开,但上述导块21的形态可多样地变更。
图14及图15表示本发明的其他实施例,上述从动齿轮22b利用与上述旋转轴22a相结合的平齿轮。
并且,在驱动马达24的外侧结合有转动本体24d,上述转动轴24b设置于上述转动本体24d。
并且,上述驱动齿轮24a以可旋转的方式与上述转动本体24d相结合,利用通过锥齿轮24e与上述驱动马达24的驱动轴相连接的平齿轮。
并且,上述转动本体24d设有通过形成于上述外壳10的上部面的导孔16向上侧延伸的杆24f。
上述导孔16呈以上述旋转轴24b为中心的弧形状,当用户抓住上述杆24f侧向推动时,上述转动本体24d和驱动马达24侧向转动,以使上述驱动齿轮24a选择性地与多个驱动齿轮22b中的一个相结合。
并且,在上述杆24f的上端设有被弹性部件24h向上侧加压的按钮24g,上述加压检测机构28设置于上述杆24f的上端,当用户向下侧加压按钮24g时,上述控制机构50可检测这一情况。
并且,在上述转动轴24b的周边面形成有三个固定槽24i,上述固定机构29设置于上述外壳10,当上述驱动马达24侧向转动,上述驱动齿轮24a与多个从动齿轮22b中的一个相结合时,设置于上述固定机构29的固定条29a选择性地与上述固定槽24i相结合,以防止上述转动轴24b和驱动马达24侧向转动的方式固定。
因此,当用户向下侧按压上述按钮24g时,上述控制机构50使上述驱动马达24反向驱动来使上述料丝1后退之后,解除上述固定机构29的固定,从而可调节成用户侧向推动上述杆24f来使驱动马达24的驱动齿轮24a与其他从动齿轮22b相结合。
用于实施发明的形态在上述的用于实施发明的最佳形态中一同记述。
