本示例实施例提供了一种刀口检验装置的结构示意图，参照图1所示，该刀口检验装置可以包括伸缩组件1、与刀口B(blade)所在直线平行的运动区间2、驱动组件3和参数获取模块4；伸缩组件1的第一端1A与刀口接触，第二端1B位于运动区间2处并且可以沿着运动区间2运动，且伸缩组件1的第一端与第二端的连线与刀口所在直线垂直；驱动组件3驱动伸缩组件1在与刀口所在直线平行的方向移动；参数获取模块4用于获取第一参数。
在本实施例中，运动区间2可以是容纳伸缩组件1的第二端的凹槽，使得该第二端可以在运动区间2限定的范围内移动。本公开不限于此，运动区间2也可以是用于容纳、限定或引导伸缩组件1的其它结构。驱动组件3可以提供机械力或电磁力，以使伸缩组件在运动区间2限定的范围内沿着平行于刀口B的方向运动。
本示例实施例提供的刀口检验装置包括伸缩组件、驱动组件及参数获取模块，驱动组件用于驱动伸缩组件在刀口所在直线平行的方向移动，参数获取模块用于获取驱动组件的第一端在垂直于刀口所在直线的方向的位移，通过位移值可快速检验印刷刮刀是否存在缺陷，克服人眼观察印刷刮刀刀口缺陷时速度慢且不易分辨缺口深浅等的缺点，进而有效控制工艺制程，使每批次生产的产品不会因为印刷刮刀的缺陷导致粘合剂的印刷面的形貌不同，从而满足生产需求。
举例而言，刀口检验装置可以应用于玻璃脚封装OLED器件的印刷刮刀上。例如，印刷刮刀可拆卸地安装在印刷机横梁上，印刷机横梁可为长方体结构，下端开有凹槽或设有夹片等，用来固定印刷刮刀，并实现印刷刮刀的拆卸功能。当然，印刷机横梁的结构也可以为其他结构，例如，带凹槽的空心手持结构、两块可拼接夹板等；即只要能固定印刷刮刀，并方便印刷刮刀拆卸的结构均在本公开的保护范围，在此不作限定。
印刷机横梁上可固定安装一与印刷刮刀S(squeegee)的刀口B所在直线平行的平行杆，该平行杆可作为运动区间2，伸缩组件1的第二端可通过磁吸、套接、卡接、挂钩等方式固定在平行杆上，并可沿平行杆移动，即伸缩组件的第二端与平行杆的连接方式可以为多种常规方式，只要能实现可沿平行杆移动且固定在平行杆上即可，在此不作限定。伸缩组件1的第一端可通过挂钩等方式与印刷刮刀的刀口接触，当然，也可通过其他方式与印刷刮刀的刀口接触，如磁性方式等，只要不影响伸缩组件的第一端沿刀口移动即可。
驱动组件可安装于印刷机上，用于驱动伸缩组件在与刀口所在直线平行的方向移动，驱动方式可为电动驱动或机械驱动。为了保证驱动组件的第一端与第二端的连线在沿刀口移动时始终与刀口所在直线垂直，可以在平行杆上和印刷刮刀刀背上安装多个驱动块，使用电动驱动使多个驱动块的运动速度相同，从而保证伸缩组件的第一端与第二端的连线在沿刀口移动时始终与刀口所在直线垂直。
伸缩组件1可以为弹性组件，例如，弹簧组件；也可以为带延长件且可沿刀口所在直线垂直方向运动的刚性部件，例如，钢管套接 钢杆等结构。
以伸缩组件为弹性组件为例，如图2所示，伸缩组件1包括弹簧组件101，弹簧组件101的第一端与印刷刮刀的刀口接触，第二端位于与刀口所在直线平行的运动区间处并且能够沿着运动区间运动，弹簧组件101与刀口所在直线垂直；参数获取模块4包括拉力测量组件401，位于弹簧组件101的第二端，用于测量弹簧组件101的第一端受到的拉力；伸缩组件1还包括弹簧固定组件102，用于使弹簧组件101在横向移动过程中保持与刀口所在直线垂直，不发生偏斜。
举例而言，弹簧组件可以为弹簧，弹簧的第一端可为钩状，钩在印刷刮刀刀口上，第二端可为圆环，套接在平行杆上，弹簧始终处于拉伸状态，在弹簧的第二端装有拉力测量仪，拉力测量仪用来测量弹簧的第一端所受到的拉力，拉力测量仪可显示拉力值。可在伸缩组件上安装一垂直刀口所在直线的固定组件，该固定组件为刚性材质，如钢罩等，用于固定弹簧在沿刀口移动时始终与刀口所在直线垂直。当弹簧在驱动组件的驱动下沿印刷刮刀刀口所在直线平行的方向移动时，可通过计算机取值方式绘制出拉力随时间变化的曲线，并通过曲线确定印刷刮刀刀口是否存在缺陷，是否需要更换。如图3所示，为印刷刮刀刀口存在缺陷时拉力随时间变化的曲线。
以伸缩组件为刚性延长件为例，如图4所示，伸缩组件1也可以是包括延长件111，延长件的第一端与印刷刮刀的刀口接触，第二端位于与刀口所在直线平行的运动区间处并且能够沿着运动区间运动，且延长件111为刚体，参数获取模块包括位移传感器411，用于获取所述延长件111的第一端在垂直于所述刀口所在直线的方向的位移。
进一步地，伸缩组件1还包括驱动单元112，驱动单元112与延长组件111的第二端连接，以驱动延长件111在垂直于刀口所在直线的方向的运动，使延长件111的第一端与印刷刮刀的刀口保持接触。
举例而言，延长件为刚性杆，如金属杆，金属杆的第一端与印刷刮刀刀口通过金属挂钩接触，金属杆可带磁性，用于将金属杆吸附在印刷刮刀上，使金属杆与印刷刮刀很好的贴合。驱动单元可通过套 接的方式与金属杆的第二端连接，并使金属杆沿垂直于刀口所在直线的方向运动，驱动单元可通过磁吸或卡接等方式固定在水平杆上，驱动单元和金属杆同时沿刀口所在直线平行方向移动时，位移传感器获取金属杆的第一端在垂直于刀口所在直线的方向的位移。
进一步地，如图5所示，位移传感器411包括位移转换单元4111、信号放大单元4112和模数转换单元4113；位移转换单元4111用于生成与延长件的第一端在垂直于刀口所在直线的方向的位移相关的电信号；信号放大单元4112，用于对所述电信号进行放大处理；模数转换单元4113，用于将放大后的电信号转换为数字信号，并根据数字信号计算延长件的第一端在垂直于刀口所在直线的方向的位移。
举例而言，位移传感器可包括位移转换单元、信号放大单元和模数转换单元，当驱动组件驱动金属杆沿刀口所在直线平行的方向移动时，首先，位移转换单元生成与金属杆的第一端在垂直于刀口所在直线的方向的位移相关的电信号；接着，信号放大单元将电信号进行放大处理；最后，模数转换单元将放大后的电信号转换为数字信号，并根据数字信号计算金属杆的第一端在垂直于刀口所在直线的方向的位移。
在本实施例中，移转换单元4111、信号放大单元4112和模数转换单元4113可以由相应的位移转换电路、信号放大电路或数模转换电路实现。然而本公开不限于此，移转换单元4111、信号放大单元4112和模数转换单元4113也可以由被配置为执行相应操作的第一微处理器实现。在本公开的一个实施例中，第一微处理器可以表示能够执行数字逻辑运算的数字处理器单元，例如，第一微处理器可以被配置为执行存储在存储器中的计算机可读代码，从而执行相应的操作。
参数获取模块4可以通过直接方式或间接方式获取伸缩组件的第一端在垂直于所述刀口所在直线的方向的位移。间接获取方式如可以为，当形变为弹性形变时，通过弹簧拉力计将位移值转化为拉力值，通过拉力值的变化，找到刀口缺陷所在的位置。直接获取方式如可以为，当形变为两部件相对运动的位移时，直接测出位移值，进一步地可通过接入位移传感器的方式，将位移值转变为数字信号，并根据数 字信号计算伸缩组件的第一端在垂直于刀口所在直线的方向的位移。
进一步地，刀口检验装置还可包括计算单元5和报警单元6；计算单元5用于计算位移值或拉力值与预设位移值或拉力值的差值；当差值大于位移阈值或拉力阈值时，报警单元6发出警报信号。
举例而言，如图6所示，报警装置设置在印刷机横梁上，以伸缩组件为弹簧组件为例，当计算单元计算出的差值大于拉力阈值时，该差值为弹簧的第一端受到的拉力值与预设在计算单元的拉力值的绝对值，报警单元发出报警信号，该报警信号可以为声音信号，也可为光信号，还可为二者的结合，具体报警方式在此不作限定。预设在计算单元的拉力值可为同一批次印刷刮刀刀口完好时弹簧的第一端受到的拉力值。
在本实施例中，计算单元5可以由相应的计算电路实现。然而本公开不限于此，计算单元5也可以由被配置为执行相应操作的第二微处理器实现。在本公开的一个实施例中，第二微处理器可以表示能够执行数字逻辑运算的数字处理器单元，例如，第二微处理器可以被配置为执行存储在存储器中的计算机可读代码，从而执行相应的操作。
本示例性实施例提供了一种刀口检验方法的流程图，参照图7所示，该刀口检验方法可以包括如下步骤：
S101：驱动所述伸缩组件在与所述刀口所在直线平行的方向移动；
S102：获取所述第一参数，并根据所述第一参数对所述刀口进行检验；所述第一参数相关于所述伸缩组件的第一端在垂直于所述刀口所在直线的方向的位移。
步骤S101，伸缩组件在驱动组件的驱动下沿与刀口所在直线平行的方向移动，如弹簧组件或刚性延长件在驱动组件的电动驱动或机械驱动下沿与刀口所在直线平行的方向移动。
步骤S102，通过直接方式或间接方式获取伸缩组件的第一端在垂直于所述刀口所在直线的方向的位移，从而确定刀口是否磨损。
以伸缩组件为弹簧为例，弹簧在驱动组件的驱动下沿与刀口所 在直线平行的方向移动。该驱动可以为电动驱动，如驱动按钮，按下驱动按钮，弹簧开始沿与刀口所在直线平行的方向移动；该驱动也可以为机械驱动，如通过拖拽装置，拖拽弹簧沿与刀口所在直线平行的方向移动。弹簧拉力计测量弹簧的第一端在垂直于刀口所在直线的方向的拉力值，通过拉力值的变化确定刀口是否存在缺陷。
以伸缩组件为刚性延长件为例，刚性延长件在驱动组件的驱动下沿与刀口所在直线平行的方向移动，在驱动单元的驱动下沿与刀口所在直线垂直的方向运动，通过位移测量仪测量刚性延长件的第一端在垂直方向的位移确定刀口是否存在缺陷，进一步地，通过位移传感器，将刚性延长件的第一端在垂直于刀口所在直线的方向的位移转换为电信号，放大电信号，将放大后的电信号转换为数字信号，并根据数字信号计算刚性延长件的第一端在垂直于刀口所在直线的方向的位移，从而确定刀口是否存在缺陷。
另以上示例性实施例中提及的刀口检验装置适用于所有印刷修型工艺中对印刷刮刀刀口的检测。
以上示例性实施例中提到的垂直并非几何意义上的垂直，在印刷工艺中的垂直会在直角上有一定范围的偏差，直角及直角偏差范围均在本公开保护范围内。
