值得注意的是，上述步骤S203及S204的清洗过程可进行一次或多次，以确保储存槽内104及106的清洗效果。
如图3和图8所示，在步骤S205中，可利用控制单元142来控制清洗液阀开关(气动阀开关120、130)，以通入清洗溶液于涂布组件102、储存槽104及106及管路146内，因而可进行整体涂布装置100的清洗。此时，可利用控制单元142来关闭气动阀开关116、118及126及自动泵112，且开启气动阀开关120、122、124、128、130、132、134及136，接着，启动自动泵108、110及114，以通入清洗溶液于涂布组件102、储存槽104及106及管路146内。再者，在步骤S205中，可利用控制单元142来控制涂布组件102，使涂布组件102持续地喷出清洗溶液，而达到涂布组件102的清洗效果。
如图3和图9所示，在步骤S206中，可利用控制单元142来控制排空组件(自动泵112)，以排出涂布组件102、储存槽104及106及管路146内的清洗溶液。此时，可利用控制单元142来关闭气动阀开关116、118、120及122及自动泵108、110及114，且开启第五至第十一气动阀开关124-136，接着，启动自动泵112(排空组件)，以排出涂布组件102、储存槽104及106及管路146内的清洗溶液。
值得注意的是，上述步骤S205及S206的清洗过程亦可进行一次或多次，以确保整体涂布装置100的清洗效果。
在一实施例中，亦可省略上述步骤S203及S204，而直接进行上述步骤S205及S206，以同时清洗涂布组件102、储存槽104及106及管路146。然不限于此，在其它实施例中，步骤S205与S206亦可被省略。
如图3和图10所示，在步骤S207中，可更换过滤器144，避免第一液体材料或清洗溶液残留于过滤器144中。此时，可利用控制单元142来关闭气动阀开关116-136及自动泵108-114，并可手动地过滤器144。
如图3和图11所示，在步骤S208中，可利用控制单元142来控制第二液体材料阀开关(第一气动阀开关116)，以通入第二液体材料于储存槽104及106内。此时，可利用控制单元142来关闭第六至第十一气动阀开关126-136及自动泵112及114，且开启第一至第五气动阀开关116-124，接着，启动自动泵108及110，以通入第二液体材料于储存槽104及106内。在此步骤S208中，所通入的第二液体材料可与储存槽104及106内残留的溶剂(第一液体材料或清洗溶液)进行反应。此第二液体材料是在更换液体材料后储存于储存槽104及106内，亦即第二液体材料为涂布装置100所使用的新液体材料，其中此第二液体材料的种类可相同或不同于第一液体材料。
如图3和图12所示，在步骤S209中，可利用控制单元142来控制排空组件(自动泵112)，以排出储存槽104及106内的第二液体材料。因此，可通过第二液体材料来进一步清洗储存槽104及106。此时，可利用控制单元142来关闭气动阀开关116、118、120、122、128、130、132、134及136及自动泵114，且开启第五及第六气动阀开关124及126，接着，启动自动泵108、110及112，以排出储存槽104及106内的第二液体材料。
如图3和图13所示，在步骤S210中，可利用控制单元142来控制第二液体材料阀开关(第一气动阀开关116)，以通入第二液体材料于涂布组件102、储存槽104及106及管路146内，因而可通过第二液体材料来进行整体涂布装置100的清洗。再者，在步骤S210中，可利用控制单元142来控制涂布组件102，使涂布组件102在一预设时间内持续地喷出第二液体材料，而达到涂布组件102的清洗效果。此时，可利用控制单元142来关闭气动阀开关120及126及自动泵112，且开启气动阀开关116、118、122、124、128、130、132、134及136，接着，启动自动泵108、110及114，以通入第二液体材料于涂布组件102、储存槽104及106及管路146内。
如图3和图14所示，在步骤S211中，可利用控制单元142来控制涂布组件102，以停止第二液体材料的喷出，接着，可使用例如无尘布(clean wiper)来擦拭涂布组件102的喷嘴，以避免溶剂或异物的残留，因而完成涂布装置100的液体材料的更换。
值得注意的是，本实施例的控制单元142可依据一预设的更换程序或指令(instruction)来控制每一组件(自动泵108-114及气动阀开关116-136)的执行时间及次数，亦即可利用控制单元142来控制每一步骤的进行时间(例如5分钟)及次数，以确保每一步骤的执行。例如，控制单元142可控制第一液体材料的排空时间及次数、清洗溶液的通入时间及次数、清洗溶液的排空时间及次数、以及第二液体材料的通入时间及次数。
因此，当进行涂布装置100的清洗及液体材料的更换时，使用者可输入预设的程序或指令于控制单元142中，使得控制单元142可控制自动泵108-114及气动阀开关116-136来自动地进行涂布装置100的清洗及液体材料的更换，而可具有自动化的效果，以避免人为错误，并可减少维护设备的人力和时间。
由上述可知，本发明的涂布装置及其液体材料的更换方法与清洗方法可自动地进行液体材料的更换，以避免人为操作所造成的错误，并可减少在清洗涂布装置或及更换液体材料时所耗费的人力和时间。再者，由于操作的自动化，本发明的涂布装置及其液体材料的更换方法可减少更换时间，因而提升设备的产能。
综上所述，虽然本发明已以优选实施例揭露如上，但上述优选实施例并非用以限制本发明，本领域的普通技术人员，在不脱离本发明的精神和范围内，均可作各种更动与润饰，因此本发明的保护范围以权利要求界定的范围为准。
