具体实施方式
为详细说明发明的技术内容、构造特征、所达成目的及功效，下面将结合实施例并配合附图予以详细说明。其中，本例中所述的“上游”指的是靠近上件区域一侧方向，所述的“下游”指的是靠近下件区域一侧方向。
如图1所示，多工艺智能涂装流水线包括上件区域1、工艺处理区域、下件区域4、链条输送系统5、行车系统6、废水处理系统12以及控制系统。
其中，工艺处理区域包括前处理区域2、电泳区域3、后处理区域8、喷粉区域9以及喷漆区域10，前处理区域2包括脱脂池、表面调整池、磷化池、钝化池，以分别完成脱脂、表面调整、磷化、钝化工艺。电泳区域3包括电泳池，以电泳工艺。喷粉区域9包括喷粉室，以完成喷粉工艺。喷漆区域10包括喷漆室，以完成喷漆工艺。前处理区域2和电泳区域3内产生的废水统一由废水处理系统12处理，避免污染环境。结合图4、6、8、10所示，后处理区域8包括第一后处理区域81、第二后处理区域82、第三后处理区域83、第四后处理区域84。其中，第一后处理区域81包括第一加热室、第一固化室和第一强冷室；第二后处理区域82包括烘干室、第二强冷室；第三后处理区域83包括第二加热室、第二固化室、第三强冷室；第四后处理区域84包括第三固化室和第四强冷室。当然，在其他实 施例中，可仅设置喷粉区域9或仅设置喷漆区域10，还可设置其他与涂装作业相关的区域作为工艺处理区域，例如浸粉区域。
如图2、3所示，链条输送系统5包括输送轨道51、输送链条52、驱动装置53以及运载小车54。其中，输送轨道51依次循环经过上件区域1、工艺处理区域、下件区域4，输送链条52设置在输送轨道51上并由安装在输送轨道51上的驱动装置53提供行进的驱动力。运载小车54悬挂在输送链条54上，其用于载运待作业工件，运载小车54上携带有与其所载运工件相应的编码信息，该编码信息用于控制系统的控制中心对工件的识别，便于工件接下来将要进行哪种或哪几种工艺作参考。在本例中，运载小车54上配备有载码体，编码信息存储在载码体内。由于1根链条的负荷较大，因此，本例采用3条独立的链条作为输送链条52，每个输送链条52至少配备一个驱动装置53，分别牵引运载小车54沿输送轨道51移动。
输送轨道51在前处理区域2的起始处设置有第一接驳端511、在电泳区域3的末尾处设置有第二接驳端512。第一、二接驳端的设置是为了便于输送轨道51与行车系统6进行接驳，便于运载小车54的转运作业。为了便于控制系统控制运载小车54的走向，以执行哪种或哪几种工艺，第一接驳端511和第二接驳端512处分别设置有读码器71。控制系统的控制中心与各个读码器71分别信号连接，控制系统的控制中心与驱动装置53以及行车系统6分别控制连接。
行车系统6设置在前处理区域2和电泳区域3的上方，行车系统6用于将运载小车54先从第一接驳端511转运至前处理区域2内，再从前处理区域2或电泳区域3转运至第二接驳端512。此处分为两种情况，一种情况为运载小车54到达第一接驳端511，通过第一接驳端511处的读码器71读取运载小车54所载运工件的编码信息，并将此编码信息反馈至控制系统的控制中心，控制中心控制行车系统6将运载小车54仅转运至前处理区域2内并执行前处理工艺，具体为脱脂、表面调整、磷化、钝化工艺中的一种或多种，再由行车系统6将运载小车54转运至第二接驳端512处以继续沿输送轨道51行进。另一种情况为运载小车54到达第一接驳端511，通过第一接驳端511处的读码器71读取运载小车54所载运工件的编码信息，并将此编码信息反馈至控制系统的控制中心，控制中心控制行车系统6将运载小 车54仅转运至前处理区域2内并执行前处理工艺，具体为脱脂、表面调整、磷化、钝化工艺中的一种或多种，再由行车系统6将运载小车54转运至电泳区域3内执行电泳工艺，最后由行车系统6将运载小车54转运至第二接驳端512处以继续沿输送轨道51行进。
输送轨道51自第二接驳端512至下件区域4之间设置有三条工艺路线，分别为第一工艺路线L1、第二工艺路线L2和第三工艺路线L3。
其中，喷粉区域9设置在第二工艺路线L2上，喷漆区域10设置在第三工艺路线L3上，并且第一工艺路线L1和第三工艺路线L3具有第一重合段K1，第二工艺路线L2和第三工艺路线L3具有第二重合段K2，第一、二重合段二者并列设置并且均位于喷粉区域9和喷漆区域10的上游。此外，第一重合段K1的结尾处、第二重合段K2的结尾处分别设置有读码器71，便于控制系统的控制中心控制运载小车54离开当前重合段后的走向。
第一后处理区域81设置在第一重合段K1上，运载小车54经过该第一后处理区域81时依次在第一加热室、第一固化室和第一强冷室这三个处理室内停留并做后处理工艺。具体的，第一加热室的加热温度为100-150℃，加热时间为9min，第一固化室的固化温度为150-230℃，固化时间为19.8min，第一强冷室的冷却温度为室温或设定值，冷却时间10.8min。
第二后处理区域82设置在第二重合段K2上，运载小车54经过该第二后处理区域82时依次在烘干室和第二强冷室这两个处理室内停留并做后处理工艺。具体的，烘干室的烘干温度为90-130℃，烘干时间为15min，第二强冷室的冷却温度为室温或设定值，冷却时间为7.5min。
第三后处理区域83设置在第二工艺路线L2上且位于喷粉区域9的下游，运载小车54经过该第三后处理区域83时依次在第二加热室、第二固化室、第三强冷室这三个处理室内停留并做后处理工艺。具体的，第二加热室的加热温度为150-190℃，加热时间为10min，第二固化室的固化温度为180-210℃，固化时间为20min，第三强冷室的冷却温度为室温或设定值，冷却时间为12.3min。
第四后处理区域84设置在第三工艺路线L3上且位于喷漆区域10的下游，运载小车54经过该第四后处理区域84时依次在第三固化室、第四强冷室内停留并做后 处理工艺。具体的，第三固化室的固化温度为80-100℃，固化时间为30min，第四强冷室的冷却温度为室温或设定值，冷却时间为12.5min。
在其他实施例中，可仅设置两条工艺路线或设置更多条工艺路线，只要其中一条工艺路线上设置喷粉区域或喷漆区域即可，这样就可实现前处理工艺和喷粉工艺或喷漆工艺的多种组合，实现工件的涂装工艺的多样化。
