Description

三维打印后处理***及方法Three-dimensional printing post-processing system and method 技术领域Technical field
本发明主要涉及三维打印技术，尤其涉及一种三维打印后处理***及方法。The present invention mainly relates to three-dimensional printing technology, and more particularly to a three-dimensional printing post-processing system and method.
背景技术Background technique
三维打印技术，是以计算机三维设计模型为蓝本，通过软件分层离散和数控成型***，利用激光束、热熔喷嘴等方式将金属粉末、陶瓷粉末、塑料、细胞组织等特殊材料进行逐层堆积黏结，最终叠加成型，制造出实体产品。与传统制造业通过模具、车铣等机械加工方式对原材料进行定型、切削以最终生产成品不同，三维打印将三维实体变为若干个二维平面，通过对材料处理并逐层叠加进行生产，大大降低了制造的复杂度。这种数字化制造模式不需要复杂的工艺、不需要庞大的机床、不需要众多的人力，直接从计算机图形数据中便可生成任何形状的零件，使生产制造得以向更广的生产人群范围延伸。The three-dimensional printing technology is based on the computer three-dimensional design model. Through the software layered discrete and numerical control molding system, the special materials such as metal powder, ceramic powder, plastic and cell tissue are stacked layer by layer by means of laser beam and hot melt nozzle. Bonding, and finally superimposed to create a physical product. Different from the traditional manufacturing industry, the raw materials are shaped and cut by the machining methods such as mold and milling, and the final production is different. The three-dimensional printing transforms the three-dimensional entity into several two-dimensional planes, which are produced by processing the materials and superimposing them layer by layer. Reduced manufacturing complexity. This digital manufacturing model does not require complicated processes, does not require a large machine tool, does not require a lot of manpower, and can directly generate any shape parts from computer graphics data, so that manufacturing can be extended to a wider production crowd.
光固化法是目前较为成熟的一种三维打印技术，其是利用光敏树脂被紫外光照射后发生固化的原理，进行材料累加成型。采用光固化法成型的工件还需要进行例如清洗和UV(UltraViolet)二次光固化等后处理步骤。但现有的后处理***及方法进行一次处理通常需要长达数小时，处理效率非常低，这对于高速三维打印来说是不能接受的。因此，提升光固化三维打印技术的后处理的处理速度是一项亟需解决的技术问题。The photocuring method is a relatively mature three-dimensional printing technology, which is based on the principle that the photosensitive resin is cured by ultraviolet light irradiation, and the material is cumulatively formed. Workpieces formed by photocuring also require post-treatment steps such as cleaning and UV (UltraViolet) secondary photocuring. However, the existing post-processing systems and methods usually take up to several hours to process, and the processing efficiency is very low, which is unacceptable for high-speed three-dimensional printing. Therefore, improving the processing speed of the post-processing of the photo-curing three-dimensional printing technology is an urgent technical problem to be solved.
此外，现有的后处理***均需要人工来操作进行，不是自动化地进行，这同样导致了后处理的效率低下。In addition, existing aftertreatment systems require manual operation, not automated, which also results in inefficient post-processing.

The dryer 10 includes a stem portion 11 and a driving member 12. The trunk portion 11 is used to drive the workpiece to be rotated at a high speed under the driving of the driving member 12, thereby removing the resin adhering to the workpiece by the centrifugal force. The stem portion 11 includes a cross arm 111, a trailing arm 112, and a rotating shaft 113. The main body of the stem portion 11 can be mainly constituted by a cross arm 111 and a trailing arm 112 connected in a T shape. The rotating shaft 113 can be disposed at the weight balance of the main body of the trunk portion 11, so that the weights of the trunk portions 11 on both sides of the rotating shaft 113 are equal or approximately equal, so that the trunk portion 11 can be balanced while rotating to avoid unnecessary vibration. Preferably, as shown in FIG. 3, the rotating shaft 113 is disposed on the trailing arm 112. As shown in Fig. 3, the rotating shaft 113 of the present embodiment is arranged in the horizontal direction, that is, the trunk portion 11 is rotated in the vertical direction. The driving member 12 may include a motor 121 and a belt 122 that rotates the rotor under the driving of electric energy, and transmits the rotation to the rotating shaft 113 through the belt 122, thereby driving the trunk portion 11 to rotate integrally. It can be understood that the driving member 12 can also use, for example, an engine or the like as a driving source, and a gear set or the like as a transmission member, which is not limited in the present invention.
横臂111具有由托板111a1和向内延伸的两个侧壁111a2构成的容纳空间111a。在需要对工件进行甩干时，可以将盛放有工件的托盘2***到容纳空间111a中。容纳空间111a内还可以设置有用于固定工件的固定部件111b，以避免在托盘2内的工件在跟随甩干部11转动时，工件晃动、移动、衰落等造成工件间互相碰撞、摩擦等造成的损伤。托板111a1和侧壁111a2上可以设置有多个通孔，以利于甩干时树脂的排出。优选地，托板111a1的镂空率高于侧壁111a2的镂空率。托板111a1的镂空率优选地大于等于50％。The cross arm 111 has an accommodation space 111a composed of a pallet 111a1 and two side walls 111a2 extending inward. When it is necessary to dry the workpiece, the tray 2 containing the workpiece can be inserted into the accommodating space 111a. A fixing member 111b for fixing the workpiece may be disposed in the accommodating space 111a to prevent damage caused by collision, friction, and the like between the workpieces caused by swaying, moving, fading, etc. of the workpiece in the tray 2 when the workpiece is rotated. . A plurality of through holes may be formed in the tray 111a1 and the side wall 111a2 to facilitate the discharge of the resin during drying. Preferably, the blanking rate of the pallet 111a1 is higher than the hollowing ratio of the side wall 111a2. The hollow ratio of the pallet 111a1 is preferably 50% or more.
固定部件111b可以包括一压板111b1、多个弹簧111b2、拉手111b3和第一传动组件111b4。多个弹簧111b2的两端分别与侧壁111a2和压板111b1连接，以将压板111b1连接侧壁111a2上，并提供固定工件所需要的压紧力。拉手111b3通过第一传动组件111b4与压板111b1连接，用于在拉动拉手111b3时，使压板111b1远离工件，此时，弹簧111b2被压缩。在松开拉手111b3时，压板111b1能够在弹簧111b2的作用下压紧工件，从而固定工件。优选地，压板111b1在面对工件的一面设置有柔性材料，以提供更大的接触面积，并对工件提供更好的保护。The fixing member 111b may include a pressing plate 111b1, a plurality of springs 111b2, a handle 111b3, and a first transmission assembly 111b4. Both ends of the plurality of springs 111b2 are respectively coupled to the side wall 111a2 and the pressing plate 111b1 to connect the pressing plate 111b1 to the side wall 111a2 and provide a pressing force required to fix the workpiece. The handle 111b3 is coupled to the pressure plate 111b1 through the first transmission assembly 111b4 for moving the pressure plate 111b1 away from the workpiece when the handle 111b3 is pulled, at which time the spring 111b2 is compressed. When the handle 111b3 is released, the pressing plate 111b1 can press the workpiece under the action of the spring 111b2 to fix the workpiece. Preferably, the pressure plate 111b1 is provided with a flexible material on one side facing the workpiece to provide a larger contact area and to provide better protection to the workpiece.
纵臂112在远离横臂111的一端设置有配重块112a，以平衡纵臂112两端的转动惯量。在一优选的实施例中，配重块112a可以在纵臂112上滑动，以根据工件重量的不同而进行相应的调整，从而使纵臂112两端的转动惯量平衡。如图3所示，纵臂112与横臂111连接的一端分开为两个分支，而远离横臂111的一端是整合的，也就是说纵臂112具有类似于“Y”的形状。纵臂112的两个分支分别与两个侧壁111a2连接。如此，在两个分支与两个侧壁111a2所形成的空间内可以设置拉手111b3和第一传动组件111b4等部件。当然可以理解地，纵臂112还可以采用完全一体的部件，本发明对纵臂112的具体形体并不加以限制。优选地，纵臂112可以主要由具有镂空的金属板制成，如此可以在保证所需的刚性要求下，降低重量，也就降低了对驱动部件12等的要求。The trailing arm 112 is provided with a weight 112a at an end remote from the cross arm 111 to balance the moment of inertia of the trailing arm 112. In a preferred embodiment, the weight 112a can be slid over the trailing arm 112 to adjust accordingly to the weight of the workpiece to balance the moment of inertia across the trailing arm 112. As shown in FIG. 3, one end of the trailing arm 112 connected to the cross arm 111 is divided into two branches, and one end away from the cross arm 111 is integrated, that is, the trailing arm 112 has a shape similar to "Y". The two branches of the trailing arm 112 are respectively connected to the two side walls 111a2. Thus, the handle 111b3 and the first transmission component 111b4 and the like can be disposed in the space formed by the two branches and the two side walls 111a2. It will of course be understood that the trailing arm 112 may also utilize a completely integral component, and the present invention does not limit the specific shape of the trailing arm 112. Preferably, the trailing arm 112 can be made primarily of sheet metal having a hollowed out shape so that the weight can be reduced while ensuring the required rigidity, thereby reducing the requirements on the drive member 12 and the like.
