Description

立体打印机
技术领域
本发明是有关于一种打印装置，且特别是有关于一种立体打印机。
背景技术
3D打印(3D printing)为快速成形技术的一种，其运用粉末状金属或塑料等可粘合材料，通过逐层堆栈累积的方式来构造物体，即「积层制造」。目前，玩具组件、机械零件或人体骨件，皆可使用3D打印快速制成，使3D打印逐渐成为大众普及的技术。
然而，立体打印机(3D printer)的Z轴通常需要承载整个平台的重量，所以会选用螺杆，但是螺杆与马达的同心度往往难以对齐。如果马达轴心与螺杆轴心没有对齐，将会造成螺杆摇晃，进而导致3D打印成品产生明显锯齿形横纹。
有鉴于此，本发明人遂针对上述现有技术，特潜心研究并配合学理的运用，尽力解决上述的问题点，即成为本发明人开发的目标。
发明内容
本发明提供一种立体打印机，其利用线性滑轨件限制可移动构件的前后位移，限位件限制可移动构件的左右位移，使可移动构件稳定不偏摆地朝直向螺杆的轴向进行升降，以达到升降机构具有稳定直线平移的优点。
于本发明实施例中，本发明提供一种立体打印机，包括：一平台，具有一料槽；一升降机构，固定于该平台，该升降机构包括：一直向螺杆；一线性滑轨件，与该直向螺杆呈平行配置；一可移动构件，一端设有一内螺孔，另一端具有一导引部，该内螺孔与该直向螺杆相互啮合，该导引部纵向滑接于该线性滑轨件，而令该可移动构件能够与该直向螺杆相互螺接传动；一支架，设置在该可移动构件的横向两侧；以及一对限位件，分别被夹掣在该可移动构件的两侧与该支架之间，每一该限位件一端固接于该可移动构件，另一端具有一滑移部，各该滑移部抵接于该支架；以及一承载座，固接于该可移动构件，该承载座能够跟随该可移动构件朝接近或远离该料槽方向移动。

有关本发明之详细说明及技术内容，将配合图式说明如下，然而所附图式仅作为说明用途，并非用于局限本发明。
请参考图1至图3所示，本发明提供一种立体打印机，此立体打印机100主要包括一平台20、一升降机构10及一承载座30。
如图1至图3所示，平台20具有一料槽201，此升降机构10主要包括一直向螺杆1、一线性滑轨件2、一可移动构件3、一支架4及一对限位件5，升降机构10固定于平台20，承载座30固接于可移动构件3，承载座30能够跟随可移动构件3朝接近或远离料槽201方向移动。
线性滑轨件2与直向螺杆1呈平行配置，且线性滑轨件2为一直向凸条21，即直向凸条21与直向螺杆1呈平行配置。
可移动构件3一端设有一内螺孔31，另一端具有一导引部32，内螺孔31与直向螺杆1相互啮合，导引部32纵向滑接于线性滑轨件2，而令可移动构件3能够与直向螺杆1相互螺接传动，即直向螺杆1之旋转运动能驱动可移动构件3朝直向螺杆1的轴向移动。
详细说明如下，可移动构件3的两侧分别设有一螺固孔33，可移动构件3包含一承接架35、一滑块36及一螺帽37，承接架35与滑块36相互固接，导引部32包含自滑块36开设的一滑槽361，滑槽361与直向凸条21相互嵌合及滑移，螺帽37固接于承接架35上，内螺孔31形成在螺帽37的内部，螺固孔33自承接架35的两侧开设。
支架4设置在可移动构件3的横向两侧，支架4具有一底板41及自底板41两侧延伸有二侧板42，且直向凸条21固定于底板41。
各限位件5分别被夹掣在可移动构件3的两侧与支架4之间，每一限位件5一端固接于可移动构件3，另一端具有一滑移部51，各滑移部51抵接于支架4的各侧板42。
进一步说明如下，本发明第一实施例的每一限位件5为一滑接柱52，每一滑移部51为自滑接柱52朝接近支架4方向延伸的一弧形凸块521，每一滑接柱52的外周缘设有一外螺纹522，各外螺纹522与各螺固孔33相互螺合，使各滑接柱52固接于可移动构件3的两侧。
如图2所示，本发明升降机构10更包括一马达7，马达7安装于支架4，直向螺杆1一端连接于马达7且跟随马达7旋转，另一端与内螺孔31相互啮合。
如图1至图3所示，本发明立体打印机100的组合，其利用平台20具有料槽201；升降机构10固定于平台20，线性滑轨件2与直向螺杆1呈平行配置；可移动构件3一端设有内螺孔31，另一端具有一导引部32，内螺孔31与直向螺杆1相互啮合，导引部32纵向滑接于线性滑轨件2，而令可移动构件3能够与直向螺杆1相互螺接传动；支架4设置在可移动构件3的横向两侧；对限位件5分别被夹掣在可移动构件3的两侧与支架4之间，每一限位件5一端固接于可移动构件3，另一端具有滑移部51，各滑移部51抵接于支架4；承载座30固接于可移动构件3，承载座30能够跟随可移动构件3朝接近或远离料槽201方向移动。藉此，线性滑轨件2限制可移动构件3的前后位移，限位件5限制可移动构件3的左右位移，使可移动构件3稳定不偏摆地朝直向螺杆1的轴向进行升降，以达到升降机构10具有稳定直线平移的优点。
如图1至图3所示，本发明立体打印机100的使用状态，其利用马达7驱动直向螺杆1的旋转，直向螺杆1的旋转运动驱动可移动构件3朝直向螺杆1的轴向移动，且因线性滑轨件2限制可移动构件3的前后位移，限位件5限制可移动构件3的左右位移，使可移动构件3能稳定不偏摆地朝直向螺杆1的轴向进行升降，以达到升降机构10具有稳定直线平移的优点，让承载座30跟随可移动构件3朝接近或远离料槽201方向移动时，承载座30也能稳定不偏摆，避免承载座30上成型的3D打印成品产生锯齿形横纹。
请参考图4所示，为本发明升降机构10的第二实施例，第二实施例与第一实施例大致相同，但第二实施例与第一实施例不同之处在于限位件5的结构不同。
详细说明如下，每一限位件5为一滚珠件53，每一滚珠件53包含一套体531，每一套体531一端固接于可移动构件3，另一端设有一凹槽532，每一滑移部51为容置于凹槽532且部分外露于套体531的一滚珠533。藉此，以达到相同于第一实施例的功能及功效。
另外，可移动构件3的两侧分别设有一螺固孔33’，每一套体531的外周缘设有一外螺纹5311，各外螺纹5311与各螺固孔33’相互螺合，使各套体531固接于可移动构件3的两侧。
每一滚珠件53更包含一弹簧534，凹槽532具有一底面5321，每一弹簧534被夹置在底面5321与滚珠533之间，使弹簧534能推抵滚珠533确实地抵接于支架4，让滚珠件53能配合可移动构件3与支架4之间的间距作调整，避免可移动构件3与支架4之间的间距有落差，造成滑移部51没有抵接到支架4，进而导致可移动构件3有空间摇晃或偏摆，以加强升降机构10稳定直线平移的能力。
请参考图5所示，为本发明升降机构10的第三实施例，第三实施例与第一实施例大致相同，但第三实施例与第一实施例不同之处在于限位件5的结构不同。
进一步说明如下，每一限位件5为一滑轮件54，每一滑轮件54包含一承载座541，每一承载座541固接于可移动构件3，每一滑移部51为安装于承载座541末端的一滚轮542。藉此，以达到相同于第一实施例的功能及功效。
另外，本发明升降机构10更包括多个锁固件6，可移动构件3的两侧分别设有多个第一螺固孔34，每一承载座541设有多个第二螺固孔5411，各锁固件6分别穿固于各第一螺固孔34与各第二螺固孔5411，使各套体531固接于可移动构件3的两侧。
请参考图6所示，为本发明升降机构10的第四实施例，第四实施例与第一实施例大致相同，但第四实施例与第一实施例不同之处在于限位件5抵接于支架4的位置不同。
详细说明如下，每一侧板42末端延伸有一L型卡块421，各滑移部51抵接于各L型卡块421的内侧，使L型卡块421限制滑移部51的横向位移，让滑移部51无法摇晃或偏摆，进而可移动构件3也无法摇晃或偏摆，以增加升降机构10稳定直线平移的能力。
综上所述，本发明的立体打印机，亦未曾见于同类产品及公开使用，并具有产业利用性、新颖性与进步性，完全符合新型专利申请要件，依专利法提出申请。
