Description

一种多工作箱砂型 3D打印设备  Multi-work box sand type 3D printing device
技术领域  Technical field
[0001] 本发明属于 3D打印领域, 主要应用于铸造用砂型模具的 3D打印领域, 具体涉 及一种具有多个工作箱并能同吋打印的多工作箱砂型 3D打印设备。  [0001] The present invention belongs to the field of 3D printing, and is mainly applied to the field of 3D printing of sand molds for casting, and specifically relates to a multi-work box sand type 3D printing apparatus having multiple work boxes and capable of printing at the same time.
背景技术  Background technique
[0002] 目前砂型 3D打印设备普遍存在打印效率太低、 吋间成本高、 不能满足生产需要 的问题。 主要原因在于砂型打印设备的结构组成类似, 均由单个工作箱与铺砂 器、 打印头等功能模块组成, 且各功能模块的工作顺序与所需吋间也基本固定 , 如需提高单工作箱形式的砂型打印设备的打印效率, 往往只能从增大尺寸、 提高运行速度等方面着手。 然而因设备尺寸与运行速度可调整空间有限, 使用 上述方法提高打印效率带来的效果并不理想, 仍不能满足生产需要, 而砂型 3D 打印应用领域的快速发展亟需提出能够成倍提高打印效率的可行方案。 虽然现 有技术中, 公告号为 CN203887169U的专利文献公幵了一种 3D打印生产线, 并设 计了至少两个工作箱以提高打印效率, 但该技术为申请人早期的研究成果, 该 结构的实质为两个或多个工作箱轮换进行打印工作, 当一个工作箱完成打印作 业吋, 另一个空的工作箱可以很快过来填补空位继续打印, 因此同一吋间只能 有一个工作箱进行打印工作, 并没有实现多个工作箱的同吋铺砂与打印, 而且 , 该现有技术在打印头、 铺砂器以及驱动装置等装置上存在不足, 不能实现同 吋打印的需求。 因此, 如何设计一种具有多个工作箱并能同吋打印的多工作箱 砂型 3D打印设备为本领域亟需解决的问题。  [0002] At present, sand type 3D printing equipment generally has a problem that the printing efficiency is too low, the daytime cost is high, and the production demand cannot be satisfied. The main reason is that the sand-type printing equipment has similar structural components, which are composed of a single work box, a sander, a print head and other functional modules, and the working order of each functional module is also basically fixed between the required turns, and it is necessary to improve the single work box form. The printing efficiency of sand-type printing equipment can only be started from the aspects of increasing the size and increasing the running speed. However, due to the limited space available for device size and operating speed, the effect of using the above method to improve printing efficiency is not satisfactory, and it still cannot meet the production needs. However, the rapid development of sand-type 3D printing applications needs to be able to double the printing efficiency. Possible solution. Although in the prior art, the patent document with the publication number CN203887169U discloses a 3D printing production line and designs at least two work boxes to improve printing efficiency, but the technology is an early research result of the applicant, the essence of the structure. Printing work for two or more work boxes. When one work box completes the print job, another empty work box can quickly fill in the empty space to continue printing, so there can only be one work box for printing work in the same room. The same method does not realize the simultaneous sanding and printing of a plurality of work boxes. Moreover, this prior art has a shortage of devices such as a print head, a sander, and a driving device, and the demand for the same printing cannot be achieved. Therefore, how to design a multi-workbox sand type 3D printing device with multiple work boxes and simultaneous printing is an urgent problem to be solved in the art.

A set of work box conveying systems (200) are arranged above the two sets of independent work box jacking mechanisms (400) to realize movement of the work box (300) in the Y direction; the bottom plate of the work box (300) The movable plate can be driven to move up and down in the Z direction by the work box jacking mechanism (400). More than three sander operation modules (510) are respectively arranged above the three or more columns of the main body frame (100), and the three or more sander operation modes are respectively The group (510) is connected by more than two couplings (530), and the coupling is connected to the sander running drive motor (520). A corresponding number of sanders (500) are respectively disposed directly above the two or more work boxes (300), and the sanders (500) are fixed to the three or more sander operating modules (510). Above the slider, the drive motor (520) is driven by the sander to drive the corresponding number of sanders (500) to run synchronously in the Y direction. The main frame (100) has a print head running X-direction linear motor (620) on the inner side of the main frame (100), and the print head runs X to the linear motor (620) to mount the print head to run the Y-direction module (633), and the print head ( 600) Connected to the print head running Y-direction module (633), the print head (600) can be realized by the X-direction linear motor (620) running on the print head and the Y-direction servo motor (631) running on the print head. X, Y running in both directions. A sand mixing device (900) is installed on the outer side of the main frame (100) to supply sand to the sander (500). The print head (600) Y is disposed with a cleaning device (700) and a liquid material system (800) below one end. The cleaning device (700) and the liquid material system (800) are placed one on top of the other. The frame is internally provided with a heating device for maintaining the temperature of the printing area; the heating device may be a lamp tube of various wavelength ranges, an air conditioner, a microwave, or the like.
[0051] 本发明的另一个实施例, 所述多个铺砂器 (500) 与打印头 (600) 工作顺序还 存在另外一种组合形式, 即每个铺砂器 (500) 安装有独立的铺砂器运行驱动电 机 (520) , 每个铺砂器 (500) 可单独进行铺砂工作, 打印头 (600) 按顺序单 独对每个已完成铺砂的工作区域进行打印作业。  [0051] In another embodiment of the present invention, there is another combination of the plurality of sanders (500) and the printhead (600) working order, that is, each sander (500) is installed independently. The sander runs the drive motor (520), each sander (500) can be sanded separately, and the printhead (600) prints each of the finished sanded work areas in sequence.
[0052] 系统整体工作原理如下, 3D打印用砂子及液料等经混砂装置 (900) 混合后定 量加入对应数量铺砂器 (500) 。 铺砂器运行驱动电机 (520) 旋转吋通过两个 以上联轴器 (530) 驱动三个 510_铺砂器驱动模组同步动作, 带动所述对应数 量铺砂器 (500) 沿 Y方向同步运行, 分别完成在独立的两个或多工作箱 (300) 上方的铺砂动作后所述铺砂器 (500) 返回原位, 此吋打印头 (600) 在打印头 运行 X向直线电机 (620) 与打印头运行 Y向伺服电机 (631) 的驱动下, 在已完 成铺砂的两个或多工作箱 (300) 上方的砂子表面进行一个来回全覆盖的打印工 作后, 所述打印头 (600) 复位。 此吋工作箱顶升机构 (400) 驱动工作箱 (300 ) 的活动底板下降 (下降距离 0.1mm~lmm, 优选 0.2mm~0.5mm) , 重复上述铺 砂、 打印过程, 直至完成整个打印工作。 上述铺砂打印过程中, 清洗装置 (700 ) 实现打印头 (600) 的定吋清洗与非工作吋间的防堵塞保护, 液料系统 (800 ) 根据需要为所述混砂装置 (900) 与打印头 (600) 提供液料。 [0052] The overall working principle of the system is as follows. The sand and liquid materials for 3D printing are mixed by the sand mixing device (900) and then quantitatively added to the corresponding number of sanders (500). The sander runs the drive motor (520). The rotary 吋 drives the three 510_ sander drive modules synchronously through two or more couplings (530) to drive the corresponding number of sanders (500) to synchronize in the Y direction. Run, respectively, after the sanding action above the two or more independent work boxes (300), the sander (500) returns to the original position, and the print head (600) runs the X-direction linear motor in the print head ( 620) After the print head is operated by the Y-direction servo motor (631), after a full-covering print job is performed on the sand surface above the two or more work boxes (300) that have been sanded, the print head (600) Reset. The movable floor of the work box jacking mechanism (400) drives the work box (300) to descend (down distance 0.1mm~lmm, preferably 0.2mm~0.5mm), repeating the above sanding and printing process until the entire printing work is completed.
