Description

喷墨打印装置 技术领域
本申请涉及打印技术领域，具体涉及一种喷墨打印装置。
 背景技术
有机发光二极管(Organic Light Emitting Diode，OLED)具有全固态、超薄、无视角限制、快速响应、室温工作、易于实现柔性显示和3D显示等优点，被公认为是下一代显示的主流技术。目前OLED的发展趋势向着喷墨打印的方向进行。在打印时，需要在打印设备上悬挂一些需要使用的打印喷嘴。但是又要保证打印喷嘴的湿润性，以防止靠近打印喷嘴端的打印材料中的溶剂长时间挥发从而使打印材料干燥导致喷嘴堵塞。

请参阅图1，图1是本申请提供的喷墨打印装置的第一结构示意图。在本申请中，喷墨打印装置100包括打印头31、第一容器10、第一管路11、第一阀门12。打印头31用于释出打印材料320。第一容器10用于储存清洗打印头31的溶剂101。第一管路11的输入端与第一容器10连通。第一管路11的输出端与打印头31连通。第一阀门12设置在第一管路11上。
其中，第一容器10的顶端可以设置一开口以及一封盖（图中未示出）。封盖用于封闭开口，进而对第一容器10进行密封。当第一容器10内的溶剂101所剩不多时，可以打开封盖，通过开口向第一容器10内加入溶剂101。第一容器10可以由透明耐腐蚀的材料制成，以便于观察第一容器10内的溶剂101的余量。
其中，第一管路11可以设置在第一容器10的下方，且位于第一容器10和打印头31之间。该设置利用重力作用使得溶剂101自第一容器10顺利流入打印头31。但本申请并不限于此，比如，第一管路11也可以设置在第一容器10的上方，或与第一容器10齐平设置。对此，可通过气泵等在第一容器10中施加气压，实现溶剂101的流动，在此不再赘述。
其中，喷墨打印装置100包括多个打印头31。每一打印头31包括多个喷嘴。打印头31通过多个喷嘴释出打印材料320，以对待打印器件进行打印。通常，每一打印头31对应打印一种打印材料320。
比如，当采用喷墨打印装置100进行显示器件的发光层打印时，打印材料320可以是红色发光材料、绿色发光材料、蓝色发光材料等。每一打印头31仅打印一种打印材料320，以避免产生混色，提高打印效果。
当然，本申请提供的喷墨打印装置100还可用于打印显示器件中的有机层等，本申请对此不作具体限定。
其中，打印材料320通常为墨水。具体的，打印材料320可以是UV（Ultraviolet，紫外线）墨水、溶剂型墨水或水性墨水。UV墨水可以利用UV光能照射而产生化学反应，进而达到固化的效果。溶剂型墨水以非水溶性的有机溶剂作为溶解着色剂的主要成分，这里的着色剂既可以是颜料，也可以是染料。水性油墨是以无机溶剂水为主要载体。
其中，溶剂101可以为有机溶剂。有机溶剂易挥发，可以更快疏通打印头31的喷嘴，保持打印头31干燥整洁。比如，溶剂101可以为三乙二醇、二甲醚、二乙二醇、2-苄氧基乙醇、三甘醇丁基甲基醚、苯甲酸丁酯、邻苯二甲酸二甲酯、乙醇、N-N-二甲基甲酰胺中的一种或多种的组合。当然，在本申请中，若打印材料320为水性墨水，溶剂101也可以为水。溶剂101为水时，成本更低，且可减小对打印头31的侵蚀。
需要说明的是，当打印材料320为溶剂型墨水时，打印材料320包括有机溶剂。本申请的溶剂101可以与打印材料320中的有机溶剂相同，以更好的溶解和清洗打印头31中残留的打印材料320。当然，溶剂101也可以与打印材料320的有机溶剂不相同，本申请对此不作具体限定。
其中，第一管路11可以与打印头31固定连接。第一管路11也可以通过卡扣、螺纹等与打印头31可拆卸连接。第一管路11的材料可以根据打印材料320的种类设置。比如，第一管路11可以由环氧树脂类、聚四氟乙烯、氟橡胶类或全氟三嗪橡胶等耐腐蚀材料制成。由此，提高第一管路11的使用寿命。
其中，第一阀门12可以为手动阀门、电磁阀门或气控阀门。同理，第一阀门12的材料可以根据溶剂101的种类设置。比如，第一阀门12可以由环氧树脂类、聚四氟乙烯、氟橡胶类或全氟三嗪橡胶等耐腐蚀材料制成。由此，提高第一阀门12的使用寿命。
其中，一个第一容器10与至少一个打印头31连通。比如，第一容器10可以与打印头31一一对应连通。此时，每一第一容器10和相应的打印头31之间通过一个第一管路11连通。又比如，每一第一容器10可以用于为多个打印头31提供溶剂101。也即，一个第一容器10通过多个第一管路11分别与多个打印头31连通。
可以理解的是，喷墨打印装置100包括非工作状态和工作状态。在非工作状态，喷墨打印装置100停止喷墨打印，打印头31不再释出打印材料320。此时，第一阀门12打开，第一管路11导通。溶剂101自第一容器10流出，然后通过第一管路11流入打印头31，以对打印头31进行清洗，避免打印头31的喷嘴堵塞。在工作状态，打印头31释出打印材料320，以对待打印器件进行喷墨打印。此时，第一阀门12关闭，第一管路11断开，避免溶剂101流入打印头31，影响喷墨打印效果。
本申请提供了一种喷墨打印装置100。喷墨打印装置100包括打印头31、第一容器10、第一管路11以及第一阀门12。本申请通过在喷墨打印装置100中增设第一容器10、第一管路11以及第一阀门12。在喷墨打印装置100处于非工作状态时，第一阀门12打开，导通第一管路11。溶剂101通过第一管路11流入打印头31，进而对打印头31的喷嘴进行清洗，可以防止打印头31的喷嘴堵塞，提高打印头31的利用率。同时，相较于在喷墨打印装置100处于非工作状态时，仍需要进行持续喷墨的方式。本申请可以避免打印材料320的浪费，以及避免持续喷墨时发生漏墨对喷墨打印装置100造成腐蚀。
此外，本申请利用溶剂101对打印头31的喷嘴进行清洗，溶剂101可以溶解打印头31内残留的打印材料320。因此，更容易将残留的打印材料320清洗掉。且经溶剂101清洗后的打印头31内不再存在残留的打印材料320，因此，在喷墨打印装置100处于非工作状态时，不需要一直保持第一阀门12的打开。即，不需要利用溶剂101一直进行清洗或者间歇性清洗，从而可以节省溶剂101的用量，进一步节约资源。
在本申请中，喷墨打印装置100还包括第二容器32、第二管路33以及第二阀门34。
具体的，第二容器32设置在打印头31的上方。第二容器32用于储存打印材料320。第二管路33的输入端与第二容器32连通。第二管路33的输出端与打印头31连通。第二阀门34设置在第二管路33上。
其中，第二阀门34用于导通或断开第二管路33。具体的，第二阀门34用于在喷墨打印装置100处于非工作状态时关闭，以断开第二管路33，使得打印材料320无法自第二容器32流入打印头31。第二阀门34还用于在喷墨打印装置100处于工作状态时打开，以导通第二管路33，使得打印材料320自第二容器32流入打印头31进行喷墨打印。
其中，本申请采用的第二容器32为分体式第二容器，即第二容器32与打印头31分开设置。该设置使得第二容器32无效时，打印头31仍可以继续使用。同时也简化了用户对第二容器32的拆装过程，减少了对喷墨打印装置100人为损伤的机会。
其中，第二阀门34可以为手动阀门、电磁阀门或气控阀门。
其中，第二管路33和第二阀门34的材料均可以根据打印材料320的种类设置。比如，第二管路33和第二阀门34可以由环氧树脂类、聚四氟乙烯、氟橡胶类或全氟三嗪橡胶等耐腐蚀材料制成。由此，提高第二管路33和第二阀门34的使用寿命。
需要说明的是，在喷墨打印装置100处于非工作状态时，第二阀门34关闭，第二管路33断开。喷墨打印装置100停止喷墨打印，打印头31不再释出打印材料320。同时，第一阀门12打开，第一管路11导通，溶剂101通过第一管路11流入打印头31，实现对打印头31的清洗。在喷墨打印装置100处于工作状态时，第二阀门34打开，第二管路33导通。打印材料320自第二容器32流入打印头31。打印头31的喷嘴释出打印材料320，以对待打印器件进行喷墨打印。同时，第一阀门12关闭，第一管路11断开，避免溶剂101自第一容器10流入打印头31，影响喷墨打印效果。
可选的，在本申请中，第一管路11的输出端与第二管路33位于第二阀门34和打印头31之间的部分连通。
可以理解的是，第一管路11通过与第二管路33连通，进而和打印头31连通，可以避免在打印头31上另开设连接孔。并且，第一管路11与第二管路33连通，可以使得溶剂101从第二管路33的输出端开始进行清洗，在防止打印头31的喷嘴堵塞的同时，对第二管路33也起到了清洁的作用。由此，避免了第二管路33内存在过多残留的打印材料320，对下一次的喷墨打印产生影响。
此外，第一管路11与第二管路33连通时，第一管路11和第二管路33可以一体成型，从而简化制程工艺。当然，若第一管路11和第二管路33的管径较小，不便实现两者之间的连通时，也可以设置第一管路11与打印头31连通。
在本申请中，每一第一容器10与至少一第二容器32并排设置。即第一容器10与第二容器32通过粘结、卡扣等方式固定或可拆卸地设置在一起。比如，第一容器10可以与第二容器32一一对应设置。每一第一容器10也可以和至少两个第二容器32并排设置，本申请对此不做具体限定。
本申请将第一容器10与第二容器32并排设置在一起，可以利用第一管路11直接将第一容器10和打印头31连通，减少第一管路11与打印头31之间的反复连接以及分离的动作。
可选的，在本申请中，第一容器10以及第一管路11可以与打印头31以及第二容器32分离设置。
具体的，当喷墨打印装置100处于工作状态时，喷墨打印装置100控制第二容器32、第二管路33以及打印头31移动至相应的打印区，对待打印器件进行喷墨打印。
当喷墨打印装置100处于非工作状态时，喷墨打印装置100移动打印头31以及第二容器32，以与第一容器10以及第一管路11连通，从而进行清洗。其中，第一管路11与打印头31可以通过卡扣卡和等方式进行连接，本申请对此不作具体限定。
可以理解的是，第一容器10以及第一管路11具有一定重量，会对第二容器32以及打印头31的移动产生一定的限制。本实施例将第一容器10以及第一管路11与打印头31以及第二容器32分离设置，在进行打印时，可以减轻第二容器32和打印头31的负载，提高喷墨打印的稳定性。
在本申请中，喷墨打印装置100还包括循环组件30。循环组件30用于接收自打印头31流出的废弃液130。废弃液130包括溶剂101和打印材料320。循环组件30还用于输出溶剂101和/或打印材料320。
可以理解的是，利用溶剂101对打印头31进行清洗后，溶剂101溶解了打印头内残留的打印材料320。因此，自打印头31流出的废弃液130包括溶剂101和打印材料320。循环组件30对废弃液130进行收集。然后通过热处理、过滤处理等可以回收其中的溶剂101和/或打印材料320，从而实现资源的回收利用。
具体的，循环组件30包括收集容器13。收集容器13用于接收自打印头31流出的废弃液130。废弃液130包括溶剂101和打印材料320。
其中，收集容器13靠近第一容器10的一侧设有一开口13A。在喷墨打印装置100处于非工作状态时，打印头31与开口13A对应，以便打印头31流出的废弃液130流入收集容器13。
本申请通过设置收集容器13，对打印头31流出的废弃液130进行收集。由此，可以避免废弃液130漏出，对喷墨打印装置100造成污染或侵蚀。同时，可回收利用收集容器13内的废弃液130，提高资源利用率。此外，打印头31还可以与开口13A卡和，从而避免废弃液130中的溶剂101挥发至空气中，造成污染。
在本申请中，循环组件30还包括第三容器14、第三管路15、第三阀门16以及第四管路17。
具体的，第三管路15的输出端与第三容器14连通。第三阀门16设置在第三管路15上。第三阀门16用于控制第三管路15的导通或断开。第三容器14设置在收集容器13的下方。第三容器14用于储存自收集容器13流出的废弃液130，并用于蒸发废弃液130中的溶剂101。第三管路15的输入端与收集容器13连通。第四管路17的输入端与第三容器14连通。第四管路17的输出端与第一容器10连通。
其中，第三容器14可以是蒸馏箱，比如常压蒸馏箱、真空蒸馏箱等。蒸馏箱的工作原理为，利用液体混合物中各组分挥发度的差别，使液体混合物部分汽化并随之使蒸气部分冷凝，从而实现其所含组分的分离。则利用第三容器14，对其内的废弃液130进行加热蒸馏处理，可以将溶剂101从废弃液130中蒸发出来。
其中，第四管路17的输入端可以与第三容器14靠近收集容器13的一端连通，以便于导出蒸发的溶剂101。第四管路17的输出端与第一容器10的顶端连通，以避免第一容器10内的溶剂101通过第四管路17倒流入第三容器14。
其中，第三管路15和第四管路17的材料均可以根据打印材料320以及溶剂101的种类设置。比如，第三管路15和第四管路17可以由环氧树脂类、聚四氟乙烯、氟橡胶类或全氟三嗪橡胶等耐腐蚀材料制成。由此，提高第三管路15和第四管路17的使用寿命。
其中，第三阀门16可以是逆流阀，也可以是手动阀门、电磁阀门或气控阀门等控制阀门。逆流阀也叫单向阀，是通过管路中介质本身的流动产生的力而自动开启和关闭的，属于一种自动阀门。也即，当第三阀门16为逆流阀时，废弃液130可以自收集容器13流入第三容器14，但不能自第三容器14流入收集容器13。由此，在第三容器14内蒸发溶剂101时，可避免溶剂101反向导入收集容器13。当第三阀门16为控制阀门时，在清洗打印头31时，打开第三阀门16。在第三容器14内蒸发溶剂101时，关闭第三阀门16。
本申请通过在喷墨打印装置100中设置第三容器14、第三管路15、第三阀门16以及第四管路17，可以对第三容器14内的废弃液130进行蒸馏，使得溶剂101从第三容器14中蒸发出来，再次进入第一容器10。从而实现溶剂101的循环利用，节约成本。
在本申请中，第四管路17包括输入段17A和输出段17B。输入段17A为第四管路17靠近第三容器14的部分。输出段17B为第四管路17靠近第一容器10的部分。循环组件30还包括加热件18。加热件18设置在输入段17A。具体的，加热件18可以设置在第四管路17的输入段17A的外侧壁上。加热件18可以是加热丝。加热件18的温度可根据溶剂101的沸点进行调整，使得溶剂101在第四管路17的输入段17A保持气体状态。
本申请通过在第四管路17的输入段17A设置加热件18，可以对第四管路17进行加热，使得进入第四管路17的溶剂101保持气体状态。防止蒸发的溶剂101在第四管路17输运的过程中凝结，形成液体附着。同时，也避免蒸发的溶剂101遇冷液化倒流回第三容器14。由此，可以提高溶剂101的回收率。
进一步的，循环组件30还包括冷凝件24。冷凝件24设置在第四管路17的输出段17B。具体的，冷凝件24可以是缠绕在输出段17B外侧壁上的冷凝管。冷凝管内具有流动的冷水。也即，采用水冷的方式实现输出段17B的降温，加速气态的溶剂101的冷却凝结，使得溶剂101顺利流入第一容器10。当然，若不设置冷凝件24，也可以通过增加第四管路17的输出段17B的长度，使得气态的溶剂101在第四管路17的输出端充分冷却凝结。
在本申请中，循环组件30还包括第四容器19、第五管路20以及第四阀门21。
具体的，第五管路20的输入端与第三容器14连通。第五管路20的输出端与第四容器19连通。第四阀门21设置在第五管路20上。第四阀门21用于控制第五管路20的导通或断开。第四容器19设置在第三容器14的下方。第四容器19用于储存自第三容器14流出的蒸发溶剂101后的废弃液130。
其中，第五管路20和第四阀门21的材料均可以根据打印材料320的种类设置。比如，第五管路20和第四阀门21可以由环氧树脂类、聚四氟乙烯、氟橡胶类或全氟三嗪橡胶等耐腐蚀材料制成。由此，提高第五管路20和第四阀门21的使用寿命。
其中，第四阀门21用于在第三容器14进行蒸馏时关闭，以断开第五管路20，避免废弃液130流入第四容器19。第四阀门21还用于在第三容器14蒸馏完成时打开，以导通开第五管路20。此时，蒸发溶剂101后的废弃液130自第三容器14流入第四容器19。
可以理解的是，废弃液130包括打印头31内残留的打印材料320以及用于清洗打印头31的溶剂101。因此，在第三容器14对废弃液130蒸馏后，溶剂101蒸发，余下的基本为打印材料320。因此，本申请设置第四容器19储存蒸馏后的废弃液130，可以实现打印材料320的回收利用，降低成本。
在本申请中，可根据喷墨打印装置100的工作进程，手动控制或软件控制第一阀门12、第二阀门34、第三阀门16以及第四阀门21打开或关闭。
比如，在本申请中，喷墨打印装置100还包括控制单元22。控制单元22分别与第一阀门12、第二阀门34以及第四阀门21连接。控制单元22用于分别控制第一阀门12、第二阀门34以及第四阀门21打开或关闭，进而使喷墨打印装置100在各阶段正常运行。
可选的，当第三阀门16为控制阀门时，控制单元22可以分别与第一阀门12、第二阀门34、第三阀门16以及第四阀门21连接。控制单元22用于根据设定的程序分别控制第一阀门12、第二阀门34、第四阀门21以及第三阀门16打开或关闭，进而使喷墨打印装置100在各阶段正常运行。
在本申请中，喷墨打印装置100还包括粘度感应器23。粘度感应器23设置在第三容器14的内侧壁或底壁。粘度感应器23与控制单元22连接。粘度感应器23用于获取第三容器14内的废弃液130的粘度值。控制单元22用于根据粘度值控制第四阀门21打开或关闭。
可以理解的是，喷墨打印装置100使用的打印材料均具有一定的粘稠度。第三容器14对废弃液130中的溶剂101进行蒸发，会不断提高废弃液130的浓度。本申请在第三容器14内设置粘度感应器23，可以对废弃液130的粘度进行实时监测，并将检测结果传输至控制单元22。当废弃液130的粘度值大于或等于预设粘度值时，控制单元22控制第四阀门21打开，将蒸馏后的废弃液130流入第四容器19，以进行回收利用。其中，预设粘度值可根据打印材料320的粘稠度进行设定。
在本申请以上各实施例中，每一打印头31对应一个收集容器13、一个第三容器14以及一个第四容器19。但是，本申请并不限于此。
比如，请参阅图2，图2是本申请提供的喷墨打印装置的第二结构示意图。本实施例的喷墨打印装置100与上述任一实施例中的喷墨打印装置100的不同之处在于，每一收集容器13对应多个打印头31设置。
具体的，每一收集容器13可以对应2个、3个、4个或更多的打印头31设置。相应的，对应每一收集容器13设有一个第三容器14和一个第四容器19。该设置可以有效简化喷墨打印装置100的结构。同时，通过减少收集容器13、第三容器14以及第四容器19的数量，可以减少第三管路15、第三阀门16、第四管路17、第五管路20以及第四阀门21的数量，进而节约成本。
进一步的，由上述实施例可知，每一打印头31打印相应的打印材料320。则每一收集容器13与至少一个打印同一种打印材料320的打印头31对应设置。由此，在回收利用打印材料320时，可避免打印材料320混色，提高回收率。
请参阅图3，图3是本申请提供的喷墨打印装置的第三结构示意图。本申实施例提供的喷墨打印装置100与上述任一实施例中的喷墨打印装置100的不同之处在于，循环组件30不包括收集容器13。
具体的，第三管路15靠近第一容器10的端口15A用于接收自打印头31流出的废弃液130，进而流入第四容器19。相较于图1，可以增大本实施例中的第三管路15的管径，使得废弃液130顺利通过第三管路15流入第四容器19，避免废弃液130漏出。
本实施例通过去掉循环组件30中的收集容器13，可以减少废弃液130的流动路径，从而降低废弃液130泄露或者废弃液130中的溶剂101挥发的风险。同时由于减少了收集容器13，可以简化喷墨打印装置100的结构，降低生产成本。
进一步的，本申请以下实施例将以图1所示的喷墨打印装置100，对喷墨打印装置100的工作状态以及非工作状态进行详细说明，但不能理解为对本申请的限定。
请参阅图4，图4是本申请提供的喷墨打印装置处于工作状态时的结构示意图。
当喷墨打印装置100处于工作状态时，第二容器32、第二管路33以及打印头31从清洗区100A移动至打印区100B。由于第一容器10与第二容器32并排设置，因此，第一容器10和第一管路11也会移动至打印区100B。
其中，第四管路17可以是可伸缩管路。由此满足第二容器32、第二管路33以及打印头31的转移。
其中，打印区100B设有工作基台41。基台41用于放置待打印器件42。待打印器件42可以是基板或者显示器件，具体可根据实际需求放置。喷墨打印装置100移动至待打印器件42的上方，用于在待打印器件42上进行喷墨打印。当喷墨打印装置100开始打印时，第一阀门12关闭，第一管路11断开。第二阀门34打开，第二管路33导通。打印材料320自第二容器32流入打印头31，进而通过打印头31在待打印器件42上打印相应的膜层。
可选的，在喷墨打印过程中，工作基台41可以沿第一方向移动。第二容器32、第二管路33以及打印头31可以沿第二方向移动。第一方向和第二方向相互垂直，从而在待打印器件42上实现膜层打印。
需要说明的是，在喷墨打印装置100处于工作状态时，第三容器14可对其内的废弃液130进行蒸馏，实现溶剂101以及打印材料320的分离以及循环利用。上述两个过程相互独立，又同时进行，可以有效提高工作效率。
请参阅图5，图5是本申请提供的喷墨打印装置处于非工作状态时的结构示意图。
当喷墨打印装置100处于非工作状态时，第二容器32、第二管路33以及打印头31从打印区100B移动至清洗区100A。同理，第一容器10和第一管路11也会移动至清洗区100A。此时，第二阀门34关闭，第二管路33断开。打印头31不再释出打印材料320。第一阀门12打开，第一管路11导通。溶剂101自第一容器10流入打印头31，从而对打印头31的喷嘴进行清洗。清洗后形成的废弃液130通过收集容器13、第三管路15流入第三容器14。第三容器对废弃液130进行蒸馏，使溶剂101蒸发。蒸发的溶剂101通过第四管路17流入第一容器10，实现溶剂101的循环利用。随着溶剂101的蒸发，当第三容器14内的废弃液130的粘度值达到预设粘度值，基本成为打印材料320时，第四阀门21打开。废弃液130通过第五管路20流入第四容器19，从实现打印材料320的回收利用。
需要说明的是，当喷墨打印装置100处于非工作状态时，第三容器14可以同步对废弃液130中的溶剂101进行蒸馏处理。第三容器14也可以在喷墨打印装置100处于工作状态时，对废弃液130中的溶剂101进行蒸发。又或者，当废弃液130较多时，第三容器14可以在非工作状态以及工作状态均进行蒸馏操作。
此外，本申请提供的喷墨打印装置100在工作状态和非工作状态之间的转动切换方式与目前采用Auto Spitting模式的喷墨打印装置的状态转动切换基本相同。因此，对于具体的转动结构在此不再赘述。
本申请提供一种喷墨打印装置100，通过在喷墨打印装置100中增设第一容器10、第一管路11以及第一阀门12。在喷墨打印装置100处于非工作状态时，第一阀门12打开，以导通第一管路11。溶剂101通过第一管路11流入打印头31，进而对打印头31的喷嘴进行清洗，可以防止打印头31的喷嘴堵塞，提高打印头31的利用率。同时，相较于现有技术，节约了打印材料320。进一步的，通过在喷墨打印装置100中增设循环组件30，可以对溶剂101以及打印材料320进行回收利用，提高资源利用率，降低成本。
以上对本申请提供喷墨打印装置进行了详细介绍，本文中应用了具体个例对本申请的原理及实施方式进行了阐述，以上实施例的说明只是用于帮助理解本申请的方法及其核心思想；同时，对于本领域的一般技术人员，依据本申请的思想，在具体实施方式及应用范围上均会有改变之处，综上所述，本说明书内容不应理解为对本申请的限制。
