本申请的一个或多个实施例的细节在下面的附图和描述中提出。
参阅图1和图2，图1为本申请一实施例提供的自动铲模装置的示意图；图2为图1中A处的放大图。本申请一实施例提供了的自动铲模装置，用于铲切成型平台500上的模型，包括机架100、铲切组件300及驱动组件400；机架100设有避让口111，机架100用于连接成型平台500，以使成型平台500上粘附的模型从避让口111处伸出；铲切组件300滑动连接于机架100，铲切组件300包括刀片310，刀片310相对成型平台500的成型面呈夹角设置；驱动组件400连接于机架100，驱动组件400用于驱动刀片310沿第一方向移动，以使刀片310铲切成型平台500上的模型，实现模型与成型平台500分离，其中第一方向与成型面平行。
具体地，本申请中通过成型平台500连接于机架100，且使成型平台500上粘附的模型从避让口111处伸出，而刀片310相对成型平台500的成型面呈夹角设置，则当驱动组件400驱动刀片310朝向模型移动时，刀片310能够切下模型，实现模型与成型平台500分离，从而省时省力，降低了脱模难度，提高了脱模效率。其中，第一方向与成型面平行，从而使得模型被切端面具有平齐的端面，便于后期加工处理，从而提高了脱模的精度。优选地，立柱120的数量为四个，分别连接于中板110的四角处。
进一步地，第一方向为成型平台500的宽度方向，从而能够缩短刀片310的移动路径，进而缩短刀片310移动时间，提高了脱模效率。
参阅图1，在其中一个实施例中，机架100包括中板110和立柱120；立柱120的一端连接于中板110，立柱120用于支撑中板110；避让口111贯穿设置于中板110上，成型平台500置于中板110的一侧，成型平台500上粘附的模型从中板110的一侧穿过避让口111朝向中板110的另一侧伸出。
具体地，刀片310置于中板110的另一侧，当驱动组件400带动刀片310沿第一方向移动时，由于刀片310与成型平台500的成型面呈夹角设置，刀片310的刀刃处能够先切 入模型边缘与成型面之间，在刀片310随着驱动组件400继续沿第一方向移动的过程中，刀刃能够铲切模型，以使模型与成型面连接区域逐渐减小，直至刀片310移动至模型的外侧，从而实现模型与成型平台500分离。
参阅图1，在其中一个实施例中，成型平台500位于中板110的上方，成型平台500上粘附的模型从避让口111处朝下伸出，刀片310位于中板110的下方。当刀片310在铲切模型的过程中，模型与成型面连接区域逐渐减小，而模型与成型面之间朝向刀片310一侧的切口会在模型重力的作用下逐渐增大，从而能够减小刀片310与模型之间的接触面积，减小刀片310与模型之间的摩擦力，使得刀片310能够沿第一方向移动的更加顺畅，提高了脱模效率。当模型与成型面在刀片310的作用下完全分离时，模型会在重力作用下脱离成型面，实现脱模。
在其他实施例中，成型平台500位于中板110的下方，成型平台500上粘附的模型从避让口111处朝上伸出，刀片310位于中板110的上方。当刀片310从模型的一侧移动至模型的另一侧时，实现模型了与成型平台500分离，此时通过机械手或者手动操作可以取下模型，从而避免模型受到损伤。
需要说明的是，本实施例以成型平台500位于中板110的上方为例进行说明。
参阅图1，在其中一个实施例中，避让口111在第一方向上的尺寸大于成型平台500的尺寸，刀片310位于避让口111的下方，刀片310的刀刃用于与成型面相切。
具体地，成型平台500沿第二方向的两端被中板110支撑，避让口111能够避让刀片310的刀刃，避免刀刃与中板110接触而对中板110造成损伤。当驱动组件400带动刀片310沿第一方向移动至成型平台500的下方时，刀片310的刀刃与成型面相切，从而使得刀片310能够切下完整的模型，从而提高了脱模精度。需要说明的是，刀片310在切模过程中，刀片310与其移动方向呈钝角，从而保证刀刃先与模型接触。其中第二方向为成型平台500的长度方向。
参阅图1，在其中一个实施例中，自动铲模装置还包括收纳槽140，机架100还包括底板130，立柱120背离中板110的一端连接于底板130，收纳槽140置于底板130上，且收纳槽140的槽口朝向避让口111，收纳槽140用于收纳与成型平台500脱离的模型。
具体地，收纳槽140位于避让口111的下方，当模型与成型平台500脱离后，模型会 在重力的作用下掉落至收纳槽140内，从而便于模型的回收。
进一步地，收纳槽140槽壁的一侧设有把手141，收纳槽140能够相对于底板130移动，从而便于操作者通过把手141推拉收纳槽140，进而便于将模型从收纳槽140中取出。
参阅图1和图2，在其中一个实施例中，自动铲模装置还包括紧固件200，紧固件200设置于中板110上，并位于避让口111的至少一侧，紧固件200用于将成型平台500压紧于中板110上。
具体地，紧固件200位于避让口111第二方向的至少一侧，紧固件200能够将成型平台500压紧于中板110上，限制成型承台相对中板110移动，从而使得刀片310能够稳定的切割模型，提高了脱模的精度。优选地，紧固件200位于避让孔沿第二方向的两侧。
进一步地，通过紧固件200可以将不同尺寸的成型平台500压紧于中板110上，从而使得刀片310能够切割不同尺寸的模型，提高了自动铲模装置的适应性。优选地，紧固件200为快速夹钳。
参阅图1和图2，在其中一个实施例中，中板110上设有固定槽112，固定槽112自中板110的一侧的表面向另一侧凹陷，固定槽112与避让口111连通；固定槽112的槽底壁用于支撑成型平台500，固定槽112的槽侧壁用于限制成型平台500相对紧固件200移动。
具体地，成型平台500沿第二方向的两端置于固定槽112的槽底壁上，当位于成型平台500沿第二方向一侧的快速夹钳将成型平台500压紧于固定槽112的槽底壁时，快速夹钳会施加给成型平台500沿第二方向的作用力，而固定槽112的设置，使得固定槽112的槽侧壁能够抵接于成型平台500沿第二方向的两侧，从而能够限制成型平台500沿第二方向移动，进而提高了成型平台500的稳定性，提高了刀片310铲切模型时的准确性。
参阅图1、图2和图3，图3为本申请一实施例提供的自动铲模装置中铲切组件与驱动组件连接的示意图。在其中一个实施例中，铲切组件300还包括固定件320、支撑件330及连接件，支撑件330连接于驱动组件400的动力输出端，固定件320上设有连接通孔321，刀片310设置于固定件320上，连接件穿过连接通孔321，并用于将固定件320连接在支撑件330上；连接通孔321的孔壁和连接件之间在竖直方向具有活动间隙，以用于调节固定件320相对支撑件330在竖直方向上的位置。
具体地，驱动组件400用于驱动支撑件330沿第一方向移动，从而带动固定件320和刀片310沿第一方向移动。由于固定件320与支撑件330之间通过连接件连接，而连接通孔321的孔壁和连接件之间在竖直方向具有活动间隙，从而通过调节连接件与连接通孔321的孔壁在竖直方向上的相对位置，调节固定件320相对支撑件330在竖直方向上的位置，进而调节刀片310的刀刃相对于成型面的位置，使得刀片310的刀刃能够准确的与成型面相切，从而提高了脱模精度。
进一步地，连接件与支撑件330螺纹连接，通过转动连接件，能够将固定件320相对于支撑件330放松，从而便于调节固定件320相对于支撑件330在竖直方向上的位置；通过反向转动连接件，能够将固定件320相对支撑件330抵紧，从而使得固定件320与支撑件330稳定连接。优选地，连接件为螺钉。
参阅图3和图4，图4为本申请一实施例提供的自动铲模装置的爆炸图。在其中一个实施例中，固定件320包括第一固定块322和第二固定块323，连接通321孔设置于第二固定块323上，第一固定块322连接于第二固定块323，刀片310被夹紧在第一固定块322和第二固定块323之间。
具体地，第一固定块322与第二固定块323通过螺钉连接，通过调节第二固定块323与支撑件330之间在竖直方向上的位置，调节刀片310的刀刃与成型面之间的位置。刀片310被第一固定块322和第二固定块323夹紧，从而能够稳定夹持刀片310，提高了刀片310对模型铲切的准确度，同时，第一固定块322与第二固定块323可拆卸连接，便于更换刀片310。
进一步地，第二固定块323上设于放置槽，刀片310背离刀刃的一侧抵接于放置槽的槽壁，从而对刀片310进行限位，提高刀片310安装的稳定性。
参阅图2和图3，在其中一个实施例中，第一固定块322上设有朝向刀片310伸出并抵压于刀片310的定位件，定位件位于第一固定块322与刀片310之间的长度可调，以限制刀片310相对第一固定块322移动。
具体地，第一固定块322上设有定位通孔324，定位件穿过定位通孔324，且螺纹连接于定位通孔324的孔壁，通过转动定位件，调节定位件位于第一固定块322与刀片310之间的长度，从而能够调节定位件对刀片310的压紧程度，对刀片310起到限位作用，提 高刀片310与固定件320连接的稳定性。优选地，定位件为螺钉。
参阅图3、图4,和图5，图5为本申请一实施例提供的自动铲模装置的部分爆炸图。在其中一个实施例中，驱动组件400包括驱动件410、主动轮430、从动轮440、传送带450及两个沿第一方向延伸的丝杆420；驱动件410连接于机架100，两个丝杆420均连接于铲切组件300，其中一个丝杆420的一端连接于驱动件410的动力输出端，另一端连接于主动轮430，从动轮440连接于另一个丝杆420，传送带450被主动轮430和从动轮440张紧，在驱动件410驱动主动轮430转动时，传送带450沿第二方向做封闭环形运动，以使两个丝杆420同步转动，以带动铲切组件300沿第一方向移动，其中第二方向垂直于第一方向。
具体地，驱动组件400还包括丝杆座480，丝杆420通过丝杆座480与中板110连接，支撑件330沿第二方向的两端分别与两个丝杆420连接。为便于描述，定义与驱动件410连接的丝杆420为第一丝杆，另一个为第二丝杆。驱动件410驱动第一丝杆带动主动轮430转动，通过传送带450传动，使得从动轮440带动第二丝杆同步转动，由于支撑件330的两端分别连接于第一丝杆与第二丝杆，则支撑件330无法发生转动，则支撑件330沿第一方向移动，从而带动铲切组件300沿第一方向移动。
两个丝杆420的设置，提高了铲切组件300移动的平稳性，而主动轮430、从动轮440及传送带450的设置，使得第一丝杆和第二丝杆能够同步转动，保证了铲切组件300移动的平稳性，同时，通过一个驱动件410实现了两个丝杆420的转动，节约了能量。优选地，驱动件410为电机。
