卡接结构能够与待搬运的掩模板卡接， 且可以在连接结构的控制下在第 一状态和第二状态之间变化， 即可达到上述效果， 因此卡接结构的结构形式 可以有多种， 本实施例中， 所述卡接结构包括执行杆 23， 所述执行杆 23 的 一端具有可与待搬运的掩模板 4边缘卡接的卡槽 231， 所述执行杆 23的另一 端与所述连接结构连接。以下均以执行杆 23对掩模板搬运治具的结构进行详 细描述。 本实施例中， 所述卡槽 231的宽度与待搬运的掩模板 4的厚度相适配， 以便卡紧掩模板 4。
所述连接结构包括：
驱动杆 22， 所述驱动杆 22在所述执行杆 23位于所述第一状态时与待搬 运的掩模板 4 (待搬运的掩模板一般平行放置） 平行设置， 且所述驱动杆 22 在所述执行杆 23位于所述第二状态时与待搬运的掩模板具有一定角度，所述 驱动杆 22的第-一端枢接于相应的所述搬运支架上的横梁 1 ;
传动杆 24， 所述传动杆 24的一端与所述驱动杆 22和所述搬运支架连接 的一端枢接， 所述传动杆 24的另一端与所述执行杆 23枢接；
用于在所述执行杆 23位于所述第一状态时限定所述驱动杆 22的位置的 套杆 21，所述套杆 21与所述搬运支架连接，且罩设在所述驱动杆 22的外部， 所述套杆 21与所述驱动杆 22的第一端相对应的位置设有用于与所述执行杆 23连接的连接部 211。
本实施例中固定结构 2对于待搬运的掩模板 4的固定、 松开采用与曲柄 滑块机构相同的原理， 驱动杆 22与传动杆 24保持垂直状态， 驱动杆 22与相 应的横梁 1枢接， 传动杆 24与执行杆 23枢接， 执行杆 23与套杆 21枢接， 套杆 21用于固定执行杆 23， 确保执行杆 23的动力源只有传动杆 24传递的 力， 以确保执行杆 23的运动方向及运动角度。
驱动杆 22向靠近套杆 21的方向运动至驱动杆 22与套杆 21平行， 驱动 传动杆 24转动， 在传动杆 24的带动下， 执行杆 23向靠近待搬运的掩模板 4 的方向运动至卡槽 231与待搬运的掩模板 4相应的边缘卡接，即执行杆 23位 于第一状态， 如图 2所示； 驱动杆 22向远离套杆 21的方向运动， 驱动传动 杆 24反向移动， 在传动杆 24的带动下， 执行杆 23反向移动， 掩模板 4从卡 槽 231中脱离， 即执行杆 23位于第二状态， 如图 3所示。
本实施例中， 所述执行杆 23上设有滑动槽， 传动杆 24与所述滑动槽相 对应的位置设有通孔， 螺钉穿过该滑动槽与通孔， 将传动杆 24与执行杆 23 连接， 传动杆 24在驱动杆 22的驱动下转动， 螺钉在滑动槽内移动以带动执 行杆 23卡紧待搬运的掩模板 4或松开待搬运的掩模板 4。
为了增加人工扳动驱动杆 22的手感，以及缓冲卡槽 231与待搬运的掩模 板 4卡接的力度， 所述套杆 21与所述驱动杆 22之间设有用于在所述执行杆 23位于所述第二状态时、 所述驱动杆 22与所述套杆 21之间具有预设角度的 弹性部件。
图 4中实线表示的是执行杆 23位于第一状态时驱动杆 22、 传动杆 24、 执行杆 23的状态；虚线表示执行杆 23位于第 状态时驱动杆 22、传动杆 24、 执行杆 23的状态。
本实施例中， 所述弹性部件为弹簧， 限定了驱动杆 22的运动范围， 以便 有效的控制执行杆 23的运动范围， 使得执行杆 23位于第一状态时， 驱动杆 22与套杆 21平行， 此时执行杆 23与驱动杆 22垂直， 即与待搬运的掩模板 4 垂直， 卡槽 231与待搬运的掩模板 4卡接， 执行杆 23位于第二状态时， 驱动 杆 22与套杆 21之间的角度如图 4所示的 a角。 这降低了卡槽 231与待搬运 的掩模板 4卡接时接触的力度， 缓冲了待搬运的掩模板 4对卡槽 231的冲击 力， 避免了掩模板 4以及卡槽 231的损伤， 延长了掩模板 4搬运治具的使用 寿命。
为了防止执行杆 23位于第一状态时，卡槽 231与掩模板 4卡接的不稳定 性， 需要在掩模板 4搬运过程中使得执行杆 23保持位于第一状态， 所述固定 结构 2还包括用于在所述执行杆 23位于所述第一状态时紧固所述驱动杆 22 与所述套杆 21、 并在所述执行杆 23位于所述第二状态时松开所述驱动杆 22 与所述套杆 21的销钉 25， 所述销钉 25穿设于所述套杆 21上的第一通孔和 所述驱动杆 22上的第二通孔。
本实施例中， 所述套杆 21为截面为 U型的条形凹槽结构， 所述套杆 21 的两侧壁与所述驱动杆 22 的第一端相对应的位置向外延伸形成两个所述连 接部 211 , 部分所述执行杆 23位于所述两个连接部 211之间， 且所述执行杆 23与所述两个连接部 211的端部枢接。
执行杆 23未设置卡槽 231的一端与传动杆 24枢接，执行杆 23上与连接 部 211连接的连接点根据实际需要与卡槽 231具有预设距离， 以固定执行杆 23 , 而有利于控制执行杆 23的运动方向和运动角度。
在本发明的具体实施例中， 搬运支架用于设置固定结构 2， 以及提供人 工搬运掩模板 4的手持部位或工具搬运掩模板 4的夹持部位， 就能达到上述 的技术效果， 因此搬运支架的结构形式均可以有多种， 下面对几种可能的结 构详细描述如下。
在一个实施例中， 搬运支架包括并排设置的至少两个横梁 1， 至少两个 横梁 1之间通过连接杆连接， 每个横梁 1 的两端设有所述固定结构 2， 在搬 运掩模板 4时， 每个横梁 1的两端的固定结构 2分别与掩模板 4的相对的两 端连接以固定掩模板 4， 方便掩模板 4的搬运。
但是， 掩模板 4只有相对的两端被固定， 搬运途中如果掩模板 4发生倾 斜， 则存在， 掩模板 4从固定结构 2中拖出的风险， 为了进一歩的确保掩模 板 4在搬运过程中的安全性， 本实施例中搬运支架结构如图 1所示， 所述搬 运支架为由多个横梁 1交叉设置形成的井字形结构， 所述井字形结构的端部 均设有所述固定结构 2。
即每一所述横梁 1的两端均与相应的固定结构 2的驱动杆 22枢接，执行 杆 23位于第一状态时， 驱动杆 22与相应的横梁 1平行， 执行杆位于第::：状 态时， 驱动杆与相应的横梁 1具有一定的角度， 即图 4中所示的 a角， 以控 制执行杆 23的运动范围和运动方向。
搬运掩模板 4时， 掩模板 4的四周均被固定， 即使搬运过程中， 掩模板 4发生倾斜， 也能避免由于掩模板 4的滑动、 甚至掉落发生的损伤， 保证掩 模板 4搬运过程中的安全性。
为了与掩模板 4的尺寸相适配， 所述搬运支架包括并排设置的两个长横 梁 1和两个短横梁 1， 且为了加强搬运支架的强度， 所述两个长横梁 1之间 设有加强筋 3， 如图 1所示。
本实施例结构简图由图 4可知， 掩模板 4搬运治具包括两个机件 （机件 1为驱动杆 22和传动杆 24， 机件 2为执行杆 23 )， 两个低副， 一个高副。 高 副机构 （higher pair) 或简称作高副， 在机械工程中， 指的是机构的两构件通 过点或线的接触而构成的运动副， 例如齿轮副和凸轮副就属于高副机构。 相 对而言， 通过面的接触而构成的运动副， 叫作低副机构。 本实施例中的低副 为驱动杆 22与横梁 1构成的第一运动副，传动杆 24和执行杆 23构成的第二 运动副； 高副为执行杆 23与掩模板 4构成的运动副。 本实施例中的掩模板 4 搬运治具的自由度由以下计算公式获得： Fn=3*2-2*2-l=l (第一运动副的自 由度为 3， 第:二运动副的自由度为 2， 高副的自由度为 1 )， 即掩模板 4搬运 治具只需驱动杆 22运动形成驱动力即可完成待搬运的掩模板 4 的固定与松 开， 从而方便掩模板 4的搬运。
以上所述仅是本发明的优选实施方式， 应当指出， 对于本技术领域的普 通技术人员来说， 在不脱离本发明原理的前提下， 还可以做出若干改进和润 饰， 这些改进和润饰也应视本发明的保护范围。
