具体实施方式
为使本发明的目的、技术方案和优点更加清楚，下面将结合本发明的实施例，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
随着中国的陶瓷产业发展迅猛，陶机设备如雨后春笋般呈现在中国的几个重要的陶瓷设备产业园基地，平面喷墨打印机也是应运而生，但是陶瓷曲面喷印的方案还处于技术盲区，致使陶瓷曲面的图案只能采用人工描绘作业的方式。采用人工描绘的方式在陶瓷曲面上描绘图案，曲面陶瓷图案的制作加工完全受制于作业人员的熟练程度，大大影响了生产效率，且人工描绘出的图案存在图案不一致、不良率偏高的现象。
图1为本发明实施例提供的曲面陶瓷喷印系统的结构示意图。如图1所示，该曲面陶瓷喷印系统包括：曲面陶瓷喷印装置10以及运动工装11和喷射阀12。
其中，曲面陶瓷喷印装置10与运动工装11和喷射阀12通信连接。具体的，运动工装11包括相互连接的控制机构110和机械臂111，控制机构110与曲面陶瓷喷印装置10通信连接；机械臂111用于安装曲面陶瓷；控制机构110用于控制机械臂111带动曲面陶瓷运动。
在具体实施时，可以将曲面陶瓷固定在运动工装11的机械臂111上，机械臂111的另一端与运动工装11的控制机构110通信连接，机械臂111可相对控制机构110发生平移和/或旋转，具体的，当曲面陶瓷的当前喷印面为平面时，控制机构110控制机械臂111带动曲面陶瓷进行平面移动，当曲面陶瓷的当前喷印面为曲面时，控制机构110控制机械臂111带动曲面陶瓷进行 旋转，做曲面运动。控制机构110与曲面陶瓷喷印装置10通信连接，控制机构110接收该曲面陶瓷喷印装置10发送的指令，控制机械臂111带动曲面陶瓷做曲面轨迹运动，喷射阀12根据该曲面陶瓷喷印装置10的指令进行图案喷印。其中，曲面陶瓷喷印装置10实现对曲面陶瓷曲面轨迹运动的精准控制及对喷射阀12的精准控制，机械臂111实现对曲面陶瓷的固定，为曲面陶瓷的空间运动提供稳定的着力点。
本实施例中曲面陶瓷喷印装置为一终端，该终端可以是移动终端，也可以是固定终端。移动终端包括但不限于手机、个人数字助理(Personal Digital Assistant，简称：PDA)、平板电脑、便携设备(例如，便携式计算机、袖珍式计算机或手持式计算机)等具有显示功能的移动设备。固定终端包括但不限于门禁、智能固定电话、控制台等具有显示功能的固定设备。本实施例对终端的形式并不限定。
由于本发明提供的曲面陶瓷喷印方法是在曲面陶瓷的生坯上进图案喷印，为了避免和曲面陶瓷相连的机械臂对喷印工作的影响，机械臂的作用力点应避开喷印图案区域。因考虑到设备效率的问题，机械臂自身重量应尽量轻便，以便和曲面陶瓷一起高速运动。
本发明提供的曲面陶瓷喷印系统，可以通过重复工位的方式，实现多色同时喷印在不同曲面陶瓷的效果，也可以实现多色异步喷印在同一曲面陶瓷上的效果，进而实现多色喷印的效果，提高了喷印效率。
本发明提供的曲面陶瓷喷印方法，控制喷射阀静止不动，使曲面陶瓷在运动工装的作用下做曲面轨迹运动，实现在陶瓷曲面上进行自动喷印图案，进而相较于现有技术，本发明喷印方法喷印的图案一致性高，有效降低了不良率，提高了生产效率。
下面以具体地实施例对本发明的技术方案以及本发明的技术方案如何解决上述技术问题进行详细说明。下面这几个具体的实施例可以相互结合，对于相同或相似的概念或过程可能在某些实施例中不再赘述。下面将结合附图，对本发明的实施例进行描述。
图2为本发明实施例提供的曲面陶瓷喷印方法的流程示意图一，如图2所示，本实施例提供的曲面陶瓷喷印方法，包括：
S201：获取曲面陶瓷的三维模型和预设喷印图案；
在本实施例中，用户可以直接获取现有曲面陶瓷的平面图，通过三维软件，例如UG、AutoCAD等，构建曲面陶瓷的三维模型；也可以通过三维扫描仪(3Dimensional Scanner)扫描立体曲面陶瓷实物，通过扫描，获得曲面陶瓷表面每个采样点的三维空间坐标，进而构建曲面陶瓷的三维模型；还可以通过图像或视频建模方式由二维图像恢复曲面陶瓷的三维几何结构，构建曲面陶瓷的三维模型。预设喷印图案，可以是人为设计的，也可以是从现有图片库中复制的图案。本实施例对获取曲面陶策三维模型和预设喷印图案的方式不做具体限定。
S202：根据三维模型和预设喷印图案，生成曲面陶瓷的曲面运动轨迹和喷射阀的喷印信息；
曲面陶瓷的曲面运动轨迹，也即曲面陶瓷的运动轨迹，根据S201中获取的曲面陶瓷的三维模型，可以获取曲面陶瓷的形状信息，结合S201中获取的预设喷印图案，对曲面陶瓷的三维模型及预设喷印图案进行解析，可以生成曲面陶瓷的运动轨迹和喷射阀的喷印信息，进而，控制曲面陶瓷按其运动轨迹运动，控制喷射阀按其喷印信息进行喷印，其中，喷印信息包括喷射阀的喷射时长和喷射间隔，关于喷射时长和喷射间隔将在后面的实施例中做详细说明。
S203：根据曲面运动轨迹控制运动工装带动曲面陶瓷进行运动；
需要说明的是，在S203之前，需要预先确定喷射阀的喷嘴与曲面陶瓷喷印面之间的距离，当终端接收到用户触发的喷印指令后，向控制机构发送指令，控制机构根据该指令控制机械臂带动曲面陶瓷进行曲面轨迹运动。
S204：根据喷印信息控制喷射阀对曲面陶瓷进行喷印处理，其中，喷射阀在喷印过程中保持位置不变。
由于本实施例提供的曲面陶瓷喷印方法，喷射阀在喷印过程中保持位置不变，所以，在上述S203步骤之后，终端监测到曲面陶瓷的喷印面已经到达预定喷印位置，则可以发送指令给喷射阀，喷射阀响应该指令并控制喷射阀对曲面陶瓷进行喷印处理，其中，对喷射阀的控制主要包括喷射阀的喷射时长和喷射间隔，关于喷射时长和喷射间隔将在后面的实施例中做详细说明。
本实施例提供的曲面陶瓷喷印方法，获取曲面陶瓷的三维模型和预设喷印图案；根据三维模型和预设喷印图案，生成曲面陶瓷的曲面运动轨迹和喷 射阀的喷印信息；根据曲面运动轨迹控制运动工装带动曲面陶瓷进行运动；根据喷印信息控制喷射阀对曲面陶瓷进行喷印处理，其中，喷射阀在喷印过程中保持位置不变。本实施例控制喷射阀静止不动，使曲面陶瓷在运动工装的作用下做曲面轨迹运动，实现在陶瓷曲面上进行自动喷印图案，由于本实施例提供的曲面陶瓷喷印方法，减少了人为因素带来的影响，且可以通过终端实时监测并控制喷射阀对曲面陶瓷进行喷印，所以，通过本实施例提供的喷印方法喷印的图案一致性高，有效降低了不良率，提高了生产效率。
下面结合图3对生成曲面运动轨迹和喷印信息的过程进行详细说明，图3为本发明实施例提供的生成曲面运动轨迹和喷印信息的流程示意图，如图3所示，本实施例提供的生成曲面运动轨迹和喷印信息的方法，包括：
S301：获取预设喷印图案中的所有颜色，并提取各颜色对应的图案；
S302：根据各颜色对应的图案，得到多层图像，其中，每层图像中包括一个颜色的图案。
在上述实施例所述S301步骤后，需要由专业的图像处理软件对预设喷印图案进行分层处理，得到多层图像，具体的可以包括如上S301和S302两个步骤。预设喷印图案可能由多种颜色的图案或者线条组成，而喷射阀单次喷印只能喷射一种颜色的墨，因此，需要将预设喷印图案分层，以获取预设图案中不同颜色对应的图案，将同种颜色对应的图案做为一层图像。
通过上述S301和S302对预设喷印图案进行分层处理，得到多层图像后，需要由专业的图像处理软件对每层图像进行点阵化处理，获得喷射阀对应每层图像的喷印信息，具体的可以包括如下S303-S305几个步骤：
S303：判断每层图像中的连续的图案是否为一个，若是，则执行如下S304的操作，若否，则执行如下S305的操作；
S304：根据连续的图案的轨迹，获取喷射阀的喷印信息，喷印信息包括喷射时长；
S305：根据多个连续的图案的轨迹以及各连续的图案之间的间隔距离，获取喷射阀的喷印信息，喷印信息包括与每个连续的图案的轨迹对应的喷射时长以及与间隔距离对应的喷射间隔。
每层图像中图案颜色相同，但是每层图像有可能是一个连续的图像，也有可能有多个连续的图像，则每个连续的图像之间会有间隔，终端可以在生 成喷印信息之前判断每层图像中图案的连续性，如果判断每层图像只有一个连续的图案，则根据该连续的图案的轨迹生成喷射阀的喷印信息，该喷印信息可以为喷射阀的喷射时长，该喷射时长用于表示喷射阀在单次喷印操作中喷射工作的持续时间；如果判断每层图像有多个连续的图像，则根据多个连续的图案的轨迹及各连续的图案间的间隔距离，生成喷射阀的喷印信息，该喷印信息不仅包括喷射时长，还包括喷射间隔，该喷射时长用于表示喷射阀喷印每个连续图案时需要工作的持续时间，喷射间隔用于表示喷射阀从当前连续图案喷印结束到下一个连续图案喷印开始之间的停歇时长。
需要说明的是，由于图案可能有填充，喷射阀需要喷印图案的轮廓以及内部填充色，也可能没有填充，喷射阀只需喷印图案的轮廓，因此，前述连续的图案的轨迹可能只包括图案的轮廓，也可能既包括图案的轮廓也包括内部填充。举例来说，当需要喷印的图案有圆形和三角形，其中，圆形和三角形的颜色相同，但是两者没有相交点，且圆形有填充而三角形无填充时，喷射阀喷印圆形图案时不仅包括其轮廓，还包括圆形中的填充，由此，产生了喷印圆形图案的喷射时长，同理，存在喷印三角形图案轮廓的喷射时长，从喷完圆形图案到开始喷印三角形图案，存在一个短暂停留，该停留时间为喷射间隔，取决于圆形图案和三角形图案之间的间隔距离。
通过上述S303-S305对每层图像进行点阵化处理，获得喷射阀对应每层图像的喷印信息后，则可以执行如下S306的操作。
S306：根据每层图像中的图案和三维模型，生成曲面运动轨迹。
由于本发明提供的曲面陶瓷喷印方法中，喷射阀在喷印过程中保持不动，所以需要控制曲面陶瓷做曲面轨迹运动，以使喷射阀在曲面陶瓷预定喷射位置上喷印图案，曲面陶瓷的曲面运动轨迹可以根据预设喷印图案和曲面陶瓷的三维模型确定，而喷射阀的喷印信息可以根据每层图像上的图案信息确定。
本实施例提供的曲面陶瓷喷印方法，通过对预设喷印图案进行分层处理，得到多层图像，再对每层图像进行点阵化处理，生成曲面运动轨迹和喷印信息，进而为曲面陶瓷的曲面运动提供了精准的运动轨迹，为喷射阀提供了精准的喷印信息，通过控制曲面陶瓷进行曲面轨迹运动及控制喷射阀进行精准喷印，所以，通过本实施例提供的喷印方法喷印的图案一致性高，有效降低了不良率，提高了生产效率。
下面结合图4对本发明提供的曲面陶瓷喷印方法进行详细说明，图4为本发明实施例提供的曲面陶瓷喷印方法的流程示意图二，如图4所示，本实施例提供的曲面陶瓷喷印方法，包括：
S401：获取曲面陶瓷的三维模型和预设喷印图案；
S402：根据三维模型和预设喷印图案，生成曲面陶瓷的曲面运动轨迹和喷射阀的喷印信息；
S403：根据曲面运动轨迹控制运动工装带动曲面陶瓷进行运动；
S401-S403的实现方式与图2所示实施例中S201-S203的实现方式类似，本实施例此处不再赘述；
S404：响应用户的参数输入指令，在用户界面上显示喷印参数输入界面；
S405：获取用户通过喷印参数输入界面输入的喷印处理参数，喷印处理参数包括：喷射阀的喷射速度和单次喷射量；
S406：根据喷印信息、喷射速度和单次喷射量，控制喷射阀对曲面陶瓷进行喷印处理，其中，喷射阀在喷印过程中保持位置不变。
实施例一所述终端具有显示屏，可以将预设喷印图案、生成的曲面运动轨迹及喷射阀的喷印信息等通过显示屏显示给用户，用户可以在终端显示的用户界面上进行操作，终端接收用户触发的指令可以向用户显示喷印参数输入界面，用户通过该喷印参数输入界面输入喷射阀的喷印处理参数，该喷印处理参数可以包括喷射阀的喷射速度和单次喷射量，喷射速度和单次喷射量直接影响喷印效果，可以根据多次试验确定最佳喷印处理参数的值。由此，终端可以根据喷印信息、喷射速度和单次喷射量，控制喷射阀对曲面陶瓷的喷印，相较于现有技术而言，本实施例提供的曲面陶瓷喷印方法，终端可以精准控制曲面陶瓷的曲面轨迹运动，以及喷射阀的自动喷印，提高了生产效率，同时解决了因人为因素带来的喷印图案不一致，不良率高等问题。
具体的，上述任一实施例中的喷射阀可以为单点微滴喷射阀，前述终端显示屏上可以显示当前墨水剩余量，用户可以根据显示的剩余量及时补充墨水量，以为单点微滴喷射阀提供稳定流到性的墨水。在具体操作时，由于单点微滴喷射阀的喷射速度较高，例如可以设置喷射速度为6m/s，而喷射距离较小，只有3毫米左右，因此，可以忽略因曲面陶瓷在进行曲面运动过程中的停位不准而导致喷印的图案失真。
本实施例提供的曲面陶瓷喷印方法，用户可以在终端显示屏上输入喷射速度、单次喷射量等参数值，终端根据获取的喷印信息及用户通过参数输入界面输入的喷印参数，控制喷射阀对曲面陶瓷进行喷印处理，提升了用户体验。
