Description

3D打印笔及其使用方法 技术领域
本发明涉及3D打印技术领域,特别涉及一种3D打印笔及其使用方法。
背景技术
随着科技的发展,3D打印技术越来越普遍地应用于各个领域,与此同时,3D打印技术也以更多种类型产品的形式出现在人们的生活中,如3D打印笔就是其中一种。与3D打印机通过机械臂带动打印喷头的移动实现3D打印不同的是:3D打印笔由人手操控,3D打印笔可以根据人的意愿来实现立体作画,也就是说,用户仅仅需要通过传统的画笔操作就能够在三维环境下绘制立体图案。目前,3D打印笔采用热熔沉积技术,其内的笔墨采用热熔材料,例如PLA(聚乳酸)材料或ABS(丙烯腈-丁二烯-苯乙烯共聚物)材料,通常也称为耗材。在使用过程中,3D打印笔内的热熔材料经过加热后从笔头挤出,然后热熔材料冷却形成3D绘制的图案。
现有的3D打印笔,使用过程中,可在壳体内同时插入多种不同颜色的耗材,但是不同耗材之间无法实现同时热熔混色,色彩较单一,无法实现多种颜色混合使用。
另外,现有的3D打印笔通常仅采用单色耗材,在绘制过程中,使用者在换色时需向打印笔中加入不同颜色的耗材实现色彩的切换,如此,存在以下缺点:一方面,色彩较单一,使用过程较乏味,另一方面,需经常更换不同颜色的耗材,存在使用较不便的缺点。
另外,一种现有的彩色3D打印笔,包括打印笔主体,打印笔主体内腔顶部设有第一步进电机,第一步进电机底部固定设有支架,支架底部设有第二步进电机,第二步进电机底端连接有L棒,第二步进电机底部设有压力气泵,压力气泵底部设有笔芯组,笔芯组之间设有搅拌导杆,搅拌导杆贯穿压力气泵与第二步进电机连接,笔芯组顶部一侧均设有压力阀门开关,压力阀门开关与L棒末端卡接。使用过程中,主要通过第一步进电机控制进料,通过第二步进电机控制搅拌过程。因此,在使用过程中需双驱动作为驱动力,一方面,存在较耗能较大的问题,另一方面,在打印笔主体内设置两个驱动源,存在整体体积较大的缺点,不利于用户握持。
一种现有的3D打印笔,采用驱动齿轮带动打印耗材输送,驱动齿轮与滚轮配合保持打印耗材的输送的稳定,其中的驱动齿轮在带动耗材进料的过程中,耗材难免会发生转动,但由于位于3D打印笔内的耗材是与外部剩余的耗材卷一体的,3D打印笔内的耗材转动也会带动外部的耗材一起转动,进而容易导致外部的耗材缠绕,这便会对进料以及使用者的操作都产生影响。
另外,一种现有的自动着色的3D打印墨盒,包括墨盒本体,沿墨盒本体的轴向开设有贯穿的耗材孔,墨盒本体上设有基色区和调色区,基色区内设有三个用于放置染料粉末的调色盒,朝向耗材孔一侧的基色盒和调色盒上均开设有与耗材孔连通的着色孔,墨盒本体的外 侧壁上开设有多个分别与基色盒、调色盒连通的进风孔,墨盒本体的周向设有绕墨盒本体旋转的驱动筒,驱动筒内侧设有可向进风孔充入空气的喷嘴,喷嘴随驱动筒绕墨盒本体旋转,进风孔处铰接有能被喷嘴抵开且能自动复位的单向门。该发明的设置无需中端打印工作来增加或更换相应颜色的线型耗材,使用方便的同时保证打印工作的连续性。
上述现有的3D打印笔的结构复杂,需要向墨盒内吹气才能使墨盒内的染料粉末喷出到线型耗材上,染料粉末在喷出的过程中容易在设备的其他结构上沾染,破坏设备的整洁。同时,现有的3D打印笔在染色时,仅能染上与墨水颜色一致的色彩,而无法控制上色浓度,打印出的产品颜色单一操作性差。

具体实施方式
下面结合附图对本发明作进一步的说明。
实施例1
一种3D打印笔,如图1、图2和图8所示,包括有外形呈笔状的笔主体1,笔主体1的头部端设置有喷嘴11,笔主体1的尾端设置有电源插座12以及可拆卸插接于笔主体1内的墨盒13,墨盒13上设置有若干染色件134。笔主体1内开设有供耗材穿过的通道10,笔主体1还设置有染色机构2、进丝机构3以及搅拌机构4,染色机构2包括有多个驱动机构,驱动机构推动染色件134对耗材进行染色,进丝机构3用于将耗材向喷嘴11传输,搅拌机构4包括有用于对耗材加热熔融的加热部件41,加热部件41可设置为加热丝,搅拌机构4用于对熔融的耗材进行搅拌。
实施例2
如图2、图3和图4所示,墨盒13内分隔形成有若干个墨腔131,墨腔131内填充有储墨单元132,所述储墨单元132为储墨海绵,(在其他实施例中,也可采用高分子聚氨酯代替储墨海绵)以及彩色染料,每个墨腔131对应设置有一个出墨口133,染色件134一一对应插接于出墨口133上,彩色染料可渗透至染色件134上,染色件134具有一定弹性,染色件134可采用棒料,墨盒13的中心沿长度方向贯穿开设有供耗材通过的线材孔135,三个墨腔131呈圆周分布于墨盒13,且线材孔135位于墨盒13的中心,三个染色件134分布于 线材孔135的四周。墨盒13的端部开设有透气孔136,透气孔136与墨腔131一一对应连通,透气孔136用于保持墨腔131内外大气压强一致,防止出墨时,墨腔131内部形成负压,导致墨水无法从出墨口133流出,此外,还可防止在气压较低的环境中使用时,墨水喷出。
实施例3
如图4、图6和图7所示,驱动机构包括有滑块22、换色电机21、设于换色电机21输出轴的偏心轮盘23,偏心轮盘23包括有偏心柱231,滑块22开设有条形槽224,条形槽224的开设方向与滑块22滑移方向相垂直,偏心柱231与条形槽224滑移配合;笔主体1内设置有支架14,支架14端部开设有供滑块22滑移的三个滑槽141,换色电机21固定安装于支架14上,换色电机21驱使滑块22向靠近染色件134运动,使得染色件134贴近耗材,当滑块22远离染色件134运动时,使得染色件134远离耗材,滑块22靠近染色件134的端面开设有弧形凹槽225,弧形凹槽225与染色件134相适配,当滑块22推动染色件134靠近耗材时,染色件134对应嵌入于弧形凹槽225内,弧形凹槽225的设置,当滑块22推动染色件134时在一定程度上可对染色件134起到较好的限位作用,防止染色件134脱离滑块22。使用状态下,墨盒13插接于笔主体1内,耗材8贯穿于线材孔135,染色件134位于耗材的四周。换色电机21包括第一换色电机211、第二换色电机212和第三换色电机213,滑块22包括对应于第一换色电机211的第一滑块221、对应于第二换色电机212的第二滑块222和对应于第三换色电机213的第三滑块223,染色件134包括对应于第一滑块221的第一染色件1341、对应于第二滑块222的第二染色件1342和对应于第三滑块223的第三染色件1343。
当耗材染色时,换色电机21启动,带动偏心轮盘23转动,偏心轮盘23转动时,在偏心柱231与条形槽224的配合作用下,使得滑块22沿滑槽141向靠近染色件134的方向运动,直至染色件134与耗材侧壁相贴;当染色完成后,换色电机21驱使滑块22复位,由于染色件134不再受到滑块22的推力,即可在其自身弹力下远离耗材。
实施例4
如图4、图6和图7所示,滑块22上设置有磁性件226,笔主体1内设置有压板15、分线路板17和压块16,压板15和压块16配合将分线路板17压紧固定,压板15上还设置有感应元件151,在本实施例中感应元件151设置为霍尔传感器,霍尔传感器与磁性件226感应配合,用于检测滑块22位移后的位置,当滑块22带动磁性件226移动时,利用霍尔传感器与磁性件226之间磁场变化导致霍尔传感器产生电位差的原理,霍尔传感器可实时感应滑块22的位置进行反馈,从而在一定程度上可使染色浓度受控。压板15的中心还设置有限位插孔152,当墨盒13插入至笔主体1内时,染色件134对应插入于限位插孔152内,如此可起到快速对准、限位的作用。
如图6所示,支架14的中心开设有供耗材通过的通孔142,滑槽141分布于通孔142四周,且滑槽141与通孔142相连通,两者连通处供染色件134运动,通孔142内壁设置有三条等距分布的防抖筋143。当耗材8送入通孔142内时,防抖筋143抵于耗材的侧壁,在一定程度上可防止耗材在进料、染色过程中发生抖动,防止已经被染色的耗材经过通道时墨 水残留管壁,使得染色较均匀、染色效果更好。
如图4所示,笔主体1内设有总线路板18,电源插座12电性连接于总线路板18,总线路板18上设置有指示灯181,笔主体1的侧壁还设置有电性连接于总线路板18的换色转盘182、进丝按钮183,换色转盘182与染色机构2的换色电机21控制配合,换色转盘182用于控制不同换色电机21的切换。换色转盘182上设置有若干位置标识,位置标识包括有数字1、2、3、4、5、6、7、和8,笔主体1上设置有定位标识19,转动换色转盘182,其中一个位置标识与定位标识19相对应。当耗材被染的颜色进行更换时,转动换色转盘182,当不同的位置标识对应于定位标识19时,即可使得控制不同颜色染色件134运动的换色电机22启动,方便用户直观地进行选择和切换实现染色的换色过程。用户可根据自己的喜好,自行选择不同的颜色对耗材进行染色,如此,无需更换耗材,即可在同一根耗材上实现多色转换,无需购买不同颜色的耗材,成本也较低。
实施例5
如图8和图9所示,笔主体1内设置有安装架5及安装于安装架5上的驱动部件,驱动部件设置为驱动电机51,驱动电机51与进丝机构3间设有第一传动组件6,驱动电机51与搅拌机构4间设有第二传动组件7,驱动电机51同步作用于进丝机构3和搅拌机构4。第一传动组件6包括第一换向齿轮61;第二传动组件7包括搅拌传动齿轮71,第一换向齿轮61和搅拌传动齿轮71均同轴设于驱动电机51的输出端。当驱动电机51启动时,输出端同时带动第一换向齿轮61和搅拌传动齿轮71转动,如此即可采用同一驱动部件通过第一传动组件6和第二传动组件7同时实现双输出。
如图8和图9所示,进丝机构3包括送丝齿轮组,送丝齿轮组包括送丝主齿轮31和送丝从动轮32,送丝主齿轮31与送丝从动轮32间形成送丝通道33,送丝主齿轮31的侧壁开设有环形嵌槽311,送丝主齿轮31设有转轴312,环形嵌槽311的设置使得耗材8侧壁对应嵌入于环形嵌槽311内,耗材在周向被限位,仅能直线进丝而无法侧壁旋转,在一定程度上可防止送入的耗材由于受到前端搅拌机构4的搅拌作用而扭转、缠绕;第一传动组件6还包括同轴设于转轴312的第二换向齿轮62,第二换向齿轮62与第一换向齿轮61相啮合。耗材送入送丝通道33内,送丝主齿轮31和送丝从动轮32分别位于耗材两侧,并对耗材侧壁产生一定的夹紧力,当第一换向齿轮61转动时,带动第二换向齿轮62转动,第二换向齿轮62通过转轴312带动送丝主齿轮31转动,由于耗材侧壁贴于送丝主齿轮31的侧壁,当送丝主齿轮31转动时,即可与送丝从动轮32配合对耗材实现进丝的传送过程。送丝主齿轮31周侧开设环形嵌槽311后,形成有两道上下对称的防转筋314,送料过程中由这两道防转筋314与耗材表面发生接触,从而限制送料过程中耗材的转动。
在驱动轮的周侧开设有环形嵌槽311,从而在驱动轮的周侧设有两道上下对称的防转筋314,实现对耗材在送料过程中转动的限制,进而防止位于打印机本体外的耗材发生缠绕,同时可以避免耗材旋转导致墨盒的染色件之间互相串色的情况。
第一传动组件6驱动进丝机构3运动,进丝机构3将耗材向喷嘴11内传送,另外还通过第二传动组件7驱动搅拌机构4同步运动,搅拌机构4即可对熔融的耗材进行搅拌混匀, 如此,使得进丝和搅拌过程同步进行,实现边搅拌边出料,不易出现断料现象。此外,一方面,采用单驱动双输出的方式,具有节能减耗的效果,另一方面,在整体结构布局上具有结构更紧凑的效果,便于用户握持。
实施例6
如图4、图5、图8和图9所示,搅拌机构4包括有供耗材送入的搅拌管42,搅拌管42转动设于笔主体1内,喷嘴11内形成供搅拌管42伸入的搅拌腔111,且搅拌管42与搅拌腔111相连通,喷嘴11内壁与搅拌管42外壁相贴合形成叠置部,加热部件41设置于叠置部外,喷嘴11侧壁整体受热较均匀,使得耗材整体的熔融效果较好,有利于充分搅拌;驱动电机51通过第二传动组件7驱动搅拌管42转动,第二传动组件7还包括有连接套72、同轴设于连接套72的搅拌管齿轮721,连接套72设置为导热性较差的塑料材质,搅拌管齿轮721与搅拌传动齿轮71相啮合,当搅拌传动齿轮71转动时,即可带动搅拌管齿轮721随之转动,从而带动搅拌管42旋转实现搅拌过程,连接套72同轴套接于搅拌管42后端,搅拌管42设置为金属搅拌管42,连接套72的后端部设有扩口状的导向斜面722,当把耗材插入至连接套72内时,导向斜面722的设置可便于将耗材引导至连接套72内,实现快速、准确的插入。
由于加热部件41对搅拌腔111内进行加热,采用金属搅拌管42具有较好的导热性,能够使得搅拌腔111内的耗材迅速熔融,而采用塑料制成的连接套72连接于搅拌管42的后端的方式,由于塑料的导热性相对金属较差,且将连接套与搅拌管42分开设置为两个部件,在一定程度上可防止耗材在进入至搅拌腔111内前,因受到金属搅拌管42的热传导而发生提前熔融、软化的现象,采用塑料连接套72进行一定隔热后,可便于推入耗材。
将侧壁经多色染色的耗材送入至搅拌管42内,使得耗材前端伸入至搅拌腔111中,加热部件41发热,将搅拌腔111内的彩色耗材热熔,驱动电机51启动后,带动搅拌管42转动,如此,搅拌管42即可对搅拌腔111中熔融的彩色耗材进行搅拌混合,使得不同颜色的耗材搅拌均匀,在搅拌的同时还可推动彩色耗材向喷嘴11运动,推动过程中即可将搅拌腔111内搅拌均匀的彩色耗材从喷嘴11挤出,如此,在使用过程中可实现多色混合,经搅拌后混色较均匀、色彩质感较好。
实施例7
如图4,图5,图6,图21,和图22所示,染色单元包括有驱动机构和染色组件2,驱动机构推动染色组件2对耗材8进行染色。染色组件2包括有墨盒13和设置在墨盒13上的染色件134,墨盒13内分隔设置有若干墨腔131,墨腔131内填充有储墨单元132,该储墨单元132可为高密度聚氨酯海绵材料,在其他实施例中,也可为任何能够吸水或者吸油的材料,储墨单元132上吸附有墨水,该墨水为油性墨水。每个墨腔131对应设置有一个出墨口,染色件134一一对应插接于出墨口133上,染色棒为纤维笔头,可吸附墨腔131内的墨水对自身进行浸色。染色件134具有一定弹性,墨盒13的中心沿长度方向贯穿开设有供耗材8通过的耗材孔135,墨腔131呈圆周分布于墨盒13,且耗材孔135位于墨盒13的中心,染色件134均匀分布与耗材孔135的周围并且 与耗材孔135之间存在一定间隙。墨盒13的端部开设有透气孔136,透气孔136与墨腔131一一对应连通,透气孔136用于保持墨腔131内外大气压强一致,防止出墨时,墨腔131内部形成负压,导致墨水无法从出墨口133流出,此外,还可防止在气压较低的环境中使用时墨水喷出。
墨盒13的下端设有插接部138,打印笔主体1上与墨盒13连接的位置设有插接位,当墨盒13插接到打印笔主体1内时,插接部138与插接位精准配合插接。当墨盒13不使用时,可将保护盖137盖上,方便墨盒13的收纳,避免墨水干燥。

通过调节换色转盘182可控制不同组别的染色机构2之间实现换色过程,用户可根据自己的喜好,自行选择不同的颜色对耗材进行染色,如此,无需更换耗材,即可在同一根耗材上实现多色转换,具有色彩丰富、趣味性强的效果,使用更灵活、多样,且无需购买不同颜色的耗材,成本也较低。
在此,需要说明的是,换色电机21的顺序和染色件134顺序的排布并不局限于本实施例所述的顺序,通过程序和染色机构数量的改变,均可进行适应性调整,在其他实施例中,可采用两组染色机构、四组染色机构或其他数量的多组染色机构的方式,还可采用一个驱动机构通过联动结构分别驱动多个染色件运动的方式。此外,需要特别说明的是,使用过程中, S1-S3相关步骤还可采用先载入耗材,再上电、加热的方式。

另外,送丝主齿轮1331沿其圆周还设有环形嵌槽1335,以在其两侧形成两防转筋1336,其能够与耗材1000的表面接触,从而防止耗材1000在向前输送时发生不必要的转动。
控制组件1160用来控制3D打印笔的运行,其可以用来控制驱动电机1131和换色电机1231的转动。例如本发明这个实施例中,控制组件1160包括主线路板1161和分线路板1162,分线路板11662可以用来控制换色电机1231的操作,主线路板1161用来实现其他控制,主线路板1161和分线路板1162可以互相独立或电性连接。当然,也可以通过同一个线路板实现所有电气控制。
另外控制组件1160还包括电源模块1163、指示灯1164、换色转盘1165、进丝按钮1166和定位标识1167。电源模块1163可以是电源插座,以用来连接于外部电源。可以理解的是,电源模块1163也可以包括可充电电池。指示灯1164可以用来指示3D打印笔的运行状态,如指示电源接通状态、加热机构1400加热到达预设温度等。换色转盘1165电性连接于主线路板1161或分线路板1162,用于控制不同换色电机1231的切换。换色转盘1165上设置有多个位置标识,其被转动时,一个位置标识与设置在笔主体1110的定位标识相对应,从而示意所选择的染色颜色。
值得一提的是,供耗材1000穿过的通道1120可以通过单独的管道形成,也可以通过墨盒1210、支架1140等部件形成。例如在这个实施例中,墨盒1220设有线材孔1216,支架1140形成有通孔1145,以供耗材1000穿过。通道1120内可以设置有多条等距分布的防抖筋1121,例如可以设置在支架1140的通孔1145中,以防止耗材在向前输送和染色过程中发生抖动。
加热机构1400包括加热部件1410,加热部件1410可以是加热电阻丝、发热薄膜、金属陶瓷发热体(MCH)、PTC发热体等。在实施例中,其是加热电阻丝并电连接于控制组件1160的主线路板1161,并通过电加热的方式加热耗材1000。

实施例10
如图30所示是上述实施例的染色机构1200的变形实施方式,在这个实施例中,染色机构1200包括多个墨盒1210,每个墨盒1210安装有一个染色件1220,各个染色件1220的至少一部分能够被对应的驱动元件1233所推动。这个实施例中这些墨盒1210不需要形成线材孔1216。3D打印笔的笔主体1110还包括输送管道1170,以用来向前输送耗材1000。可以理解的是,笔主体1110的用来输送耗材的通道1120的至少一部分由输送管道1170形成,并且通道1120在对应染色机构1200的染色位置和进丝机构1300的位置使耗材1000露出以方便染色和向前进丝的驱动操作。
实施例11
如图31所示是上述实施例的3D打印笔的另一变形实施方式。在这个实施例中,3D打印笔包括染色机构1200、进丝机构1300和加热机构1400。染色机构1200包括墨盒1210、染色件1220和驱动机构1230,染色件1220位于加热机构1400的加热部件1410和进丝机构1300的送丝元件1330之间,以使耗材1000的染色位置位于进丝机构1300的送丝元件1330和加热机构1400的加热部件1410之间。
也就是说,上述实施例中,送丝元件1330将经染色后的耗材1000向加热机构1400输送。而在这个实施例中,耗材1000被进丝机构1300向前输送至位于进丝机构1300的前方的染色件1220的位置才进行染色,从而进丝机构1300的送丝元件1330如送丝齿轮、送丝螺纹或其他送丝驱动装置不会被染色,从而避免进丝机构1300的送丝元件1330上被涂上彩色染料而导致后续切换不同染色件1220对耗材1000染色时产生串色。
可以理解的是,在这个实施例中,墨盒1210位于加热机构1400和进丝机构1300之间。墨盒1210还具有多个充墨阀1217,以分别用于向对应的各个墨腔1212中充入彩色染料,这样在3D打印笔需要增添墨水时,墨盒1210不用从笔主体1100中取出。
实施例12

当染色过程开始时,驱动电机1231转动,带动第一驱动杆12381枢转,第二驱动杆12382 也被驱动转动,从而带动实施为滑块的驱动元件1233移动以与染色件1220的至少一部分相接触并推动染色件1220,使染色件1220与耗材1000相接触,从而对耗材1000进行染色操作。
当需要更换另一染色件1220对耗材1000进行染色时,驱动电机1231反转,带动第一驱动杆12381反向枢转,第二驱动杆12382也被驱动反向转动,从而带动驱动元件1233复位以与对应的染色件1220相远离。然后启动另一驱动电机1231,以驱动另一驱动元件1233与对应的另一颜色的染色件1220相接触,从而实现换色染色操作。

当需要更换另一染色件1220对耗材1000进行染色时,驱动电机1231反转,带动驱动元件1233反转以复位并与对应的染色件1220相远离。然后启动另一驱动电机1231,以驱动另一驱动元件1233与对应的另一颜色的染色件1220相接触,从而实现换色染色操作。
可以理解的是,在另外的变形实施方式中,染色件1220可以进一步地被附接于驱动元件1233,这样染色件1220可以与驱动元件1233形成一体结构,从而驱动元件1233移动时带动染色件1220移动,以使染色件1220接触和远离耗材1000。
实施例14
如图36和图37所示是本发明的3D打印笔的另外变形实施方式,其中3D打印笔包括染色机构2200,染色机构2200包括墨盒2210、染色件2220和驱动机构2230,并且染色件2220和驱动机构2230的工作方式与上述实施例有区别。更具体地,驱动机构2230包括驱动开关2231,传动部件2232和驱动元件2233。其中使用者可以手动地操作设于上述笔主体1100的驱动开关2231,以用于驱动传动部件2232移动,从而进一步地带动驱动元件2233产生位移,驱动元件2233作为一个推动元件推动染色件2220的至少一部分,如推动染色件2220的接触端部2222。
更具体地,以图36和图37中示意的结构为例,当使用者向后推动驱动开关2231时,传动部件2232向后移动,从而驱动元件2233同时也向后移动,以推动染色件2220的接触端部2222,使染色件2220的接触端部2222与耗材1000相接触,从而对耗材1000进行染色。可以理解的是,驱动元件2233可以具有推动面2234,其可以是斜面或曲面,以方便于作用于染色件2220的接触端部2222。当不需要使用这个染色件2220进行染色时,向前推动驱动开关2231,传动部件2232向前移动,从而驱动元件2233同时也向前移动,以使驱动元件2233与染色件2220的接触端部2222相远离,使染色件2220的接触端部2222与耗 材1000相分离,从而可以驱动另一驱动元件2233,以作用于另一个染色件2220从而对耗材1000进行另一种颜色的染色操作。

在这个实施例中,推动面2234在圆周方向延伸并且是曲面或斜面,其具有凸出的峰面22341和谷面22342,当驱动开关2231被转动以使传动部件2232带动驱动元件2233转动以使其峰面22341作用于染色件2220的中间部分2223时,染色件2220的中间部分2223被推动而带动其端部2222接触耗材1000,从而对耗材1000进行染色操作。当驱动开关2231被反转以使传动部件2232带动驱动元件2233反转以使其谷面22342作用于染色件2220的中间部分2223时,染色件2220的中间部分2223远离耗材1000,从而停止利用当前的染色件2220对耗材1000进行染色操作。
实施例16

可以理解的是,当利用多个驱动元件3233对多个染色件3220周期性地推动作用时,可以同时使染色件3220接触耗材1000,也可以使多个染色件3220错开时间地与耗材1000接 触。

当不需要当前工作的染色件4220对耗材1000染色时,驱动控制件4231使驱动元件4233放气,放气后的驱动元件4233不再推动染色件4220,染色件4220自动复位以与耗材1000相分离。
