下面将结合附图,对本公开一些实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本公开一部分实施例,而不是全部的实施例。基于本公开所提供的实施例,本领域普通技术人员所获得的所有其他实施例,都属于本公开保护的范围。
除非上下文另有要求,否则,在整个说明书和权利要求书中,术语“包括(comprise)”及其其他形式例如第三人称单数形式“包括(comprises)”和现在分词形式“包括(comprising)”被解释为开放、包含的意思,即为“包含,但不限于”。在说明书的描述中,术语“一个实施例(one embodiment)”、“一些实施例(some embodiments)”、“示例性实施例(exemplary embodiments)”、“示例(example)”、“特定示例(specific example)”或“一些示例(some examples)”等旨在表明与该实施例或示例相关的特定特征、结构、材料或特性包括在本公开的至少一个实施例或示例中。上述术语的示意性表示不一定是指同一实施例或示例。此外,所述的特定特征、结构、材料或特点可以以任何适当方式包括在任何一个或多个实施例或示例中。
以下,术语“第一”、“第二”仅用于描述目的,而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此,限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个该特征。在本公开实施例的描述中,除非另有说明,“多个”的含义是两个或两个以上。
在描述一些实施例时,可能使用了“连接”及其衍伸的表达。例如,描述一些实施例时可能使用了术语“连接”以表明两个或两个以上部件彼此间有直接物理接触或电接触。
“A和/或B”,包括以下三种组合:仅A,仅B,及A和B的组合。
本文中“适用于”或“被配置为”的使用意味着开放和包容性的语言,其不排除适用于或被配置为执行额外任务或步骤的设备。
另外,“基于”的使用意味着开放和包容性,因为“基于”一个或多个 所述条件或值的过程、步骤、计算或其他动作在实践中可以基于额外条件或超出所述的值。
如本文所使用的那样,“约”、“大致”或“近似”包括所阐述的值以及处于特定值的可接受偏差范围内的平均值,其中所述可接受偏差范围如由本领域普通技术人员考虑到正在讨论的测量以及与特定量的测量相关的误差(即,测量系统的局限性)所确定。
本文参照作为理想化示例性附图的剖视图和/或平面图描述了示例性实施方式。在附图中,为了清楚,放大了层和区域的厚度。因此,可设想到由于例如制造技术和/或公差引起的相对于附图的形状的变动。因此,示例性实施方式不应解释为局限于本文示出的区域的形状,而是包括因例如制造而引起的形状偏差。例如,示为矩形的蚀刻区域通常将具有弯曲的特征。因此,附图中所示的区域本质上是示意性的,且它们的形状并非旨在示出设备的区域的实际形状,并且并非旨在限制示例性实施方式的范围。
相关技术中的显示模组,需要利用弯折设备将柔性电路板中远离显示面板的部分弯折至显示面板的背侧,以减小显示装置的边框。然而,相关技术中的弯折设备,在将柔性电路板中远离显示面板的部分弯折至显示面板的背侧,柔性电路板会贴覆在显示面板的背面,这导致柔性电路板难以实现第二次弯折。
基于此,参见图1和图2,本公开的一些实施例提供了一种弯折设备100,弯折设备100用于加工待弯折器件200。
如图1所示,该弯折设备100包括固定结构1,第一驱动机构2、第一压头3、第二驱动机构4和第二压头5。如图2所示,待弯折器件200包括彼此连接的主体部分201和待弯折部分202,待弯折部分202包括依次远离主体部分201的第一部分203和第二部分204。其中,待弯折器件200中第一部分203和主体部分201之间的部分为柔性材料,第二部分与第一部分之间的部分也为柔性材料。示例性的,该待弯折器件200可以是如上所述的显示模组。待弯折器件200中的主体部分201可以为显示模组中的显示面板,待弯折器件200中的待弯折部分202可以包括柔性电路板。
其中,固定结构1被配置为固定待弯折器件200的主体部分201。第一驱动机构2与第一压头3连接,第一驱动机构2被配置为驱动第一压头3运动至第一部分203的第一表面S1上(如图3A和图3B所示),并驱动第一压头3推动第一部分203翻转至主体部分201的第一侧,使第一部分203与主体部分201平行或大致平行(如图4A和图4B所示)。第二驱动机构4与第 二压头5连接,第二驱动机构4被配置为驱动第二压头5运动至第二部分204的第二表面S2上(如图3A和3B所示)。其中,第二表面S2与第一表面S1分别位于待弯折部分202的两侧。第二驱动机构4还被配置为在第一压头3推动第一部分203的同时,驱动第二压头5拉动第二部分204翻转至主体部分201的第一侧(如图4A和图4B所示)。
其中,“大致平行”例如可以是指,第一部分203与平行于主体部分201的平面之间存在一个较小的夹角,示例性的,该夹角不超过10度。
本公开一些实施例提供的弯折设备100,包括第一驱动机构2、第一压头3,第二驱动机构4和第二压头5。其中,第一驱动机构2能够驱动第一压头3推动第一部分203翻转至主体部分201的第一侧,使第一部分203与主体部分201平行或大致平行。第二驱动机构4能够在第一压头3推动第一部分203的同时,驱动第二压头5拉动第二部分204翻转至主体部分201的第一侧。由于第二压头5与第一压头3同时动作,且第二压头5与第二部分204的第二表面S2接触,因此在第一部分203与主体部分201平行或大致平行、且第二部分204翻转至主体部分201的第一侧时,第二部分204的第二表面S2不容易与主体部分201相接触,从而使得弯折设备100在后续对待弯折器件200弯折的过程中,能够将待弯折部分202的第二部分204翻转至第一部分203远离主体部分201的一侧,也即实现了对待弯折器件200的两次弯折。
在一些实施例中,如图4A所示,在第一压头3推动第一部分203的同时,第二压头5拉动第二部分204翻转至主体部分201的第一侧,使第二部分204与主体部分201垂直或大致垂直。其中,“大致垂直”可以是第二部分204与垂直于主体部分201的平面之间存在一个较小的夹角,示例性的,该夹角不超过10度。
这样,在将第二部分204弯折至第一部分203远离主体部分201的一侧时,第一部分203不容易受到由主体部分201指向第一部分203的方向的力的作用,从而向远离主体部分201的方向运动,使得第一部分203与主体部分201之间的间距可以保持的较小,有利于使弯折后的待弯折器件具有较小的厚度。
在一些实施例中,如图5A和图5B所示,第一驱动机构2还被配置为在第一部分203与主体部分201平行或大致平行后,驱动第一压头3向远离第一部分203的方向运动。通过这样设置,避免了在将第二部分204翻转至第一部分203远离主体部分201一侧时,第二部分204与第一压头3碰撞在一起的情况发生。
在一些实施例中,如图6A和图6B所示,第二驱动机构4还被配置为在第一压头3远离第一部分203后,驱动第二压头5推动第二部分204翻转至第一部分203远离主体部分201的一侧,使第二部分204与第一部分203平行或大致平行。其中,“大致平行”可以是第二部分204与第一部分203所在的平面之间存在一个较小的夹角,示例性的,该夹角的不超过10度。
通过利用第二压头5推动第二部分204翻转至第一部分203远离主体部分201的一侧,使得待弯折部分202中位于第二部分204远离第一部分201的一侧的部分在主体部分201所在的平面上的正投影位于主体部分201的外侧。
当该待弯折器件200为待弯折的显示模组时,待弯折部分202中位于第二部分204远离第一部分203的一侧的部分可以是柔性电路板的一部分,这样在待弯折器件200的第二次弯折过程完成后,柔性电路板可以延伸至显示装置的键盘区与控制电路板电连接。
同时,由于第二压头5是在第一压头3远离第一部分203后,推动第二部分204向第一部分203远离主体部分201的一侧弯折的,因此还能够避免第二部分204与第一压头3发生碰撞,保护第二部分204不被破坏。
在一些实施例中,如图7所示,第一压头3可以包括第一吸附板31和第一抽真空装置32。其中,第一吸附板31上设置至少一个第一抽真空孔311。第一抽真空装置32与所述至少一个第一抽真空孔311连通。
其中,需要说明的是,本公开对第一吸附板31的形状和大小不做限定。示例性的,如图7所示,第一吸附板31可以是长方体。本公开对第一抽真空孔311的数量、形状、大小以及排列方式也均不做限定,只要保证第一抽真空孔311能够有效的吸附第一部分203的第一表面S1即可。示例性的,如图7所示,第一抽真空孔311的形状可以是圆形。
本公开一些实施例所提供的第一压头3包括第一抽真空装置32和设置在第一吸附板31上的至少一个第一抽真空孔311,因此在第一压头3与第一部分203的第一表面S1接触时,通过打开第一抽真空装置32即可在第一抽真空孔311与第一部分203的第一表面S1形成的空间内形成负压环境,使第一部分203的第一表面S1被吸附在第一吸附板31上。
这样,在第一压头3推动第一部分203翻转至主体部分201的第一侧的过程中,第一抽真空装置32可以一直保持开启状态,使得第一部分203与第一压头3之间不容易出现错位,也不容易分离,从而使第一部分203与主体部分201之间的弯折部分的弯折半径可以较小,弯折后的待弯折器件的厚度 较薄。
在一些实施例中,如图7所示,第二压头5包括第二吸附板51和第二抽真空装置52。其中,第二吸附板51上设置至少一个第二抽真空孔511。第二抽真空装置52与所述至少一个第二抽真空孔511连通。
需要说明的是,本公开并不对第二吸附板51的形状和大小进行限定。示例性的,如图7所示,第二吸附板51可以为长方体。本公开也不对第二抽真空孔511的数量、形状、大小和排布方式进行限定。示例性的,参见图7,第二抽真空孔511的形状可以为圆形。
本公开一些实施例所提供的第二压头5中包括第二吸附板51和第二抽真空装置52,因此在第二压头5与第二部分204的第二表面S2接触时,通过打开第二抽真空装置52可以在第二抽真空孔511与第二部分204的第二表面S2形成的空间内形成负压环境,使第二部分204的第二表面S2被吸附在第二吸附板51上。
基于此,第二抽真空装置52可以被配置为在第二压头5拉动第二部分204翻转至主体部分201的第一侧的过程中,一直保持开启状态,使得第二部分204的第二表面S2一直被吸附在第二吸附板51上,有利于避免第二部分204与第二吸附板51分离,第二部分204直接与主体部分201第一侧表面相接触的情况发生。
同样的,第二抽真空装置52可以被配置为在第二压头5推动第二部分204翻转至第一部分203远离主体部分201的一侧的过程中,一直保持打开状态,使第二部分204的第二表面S2一直被吸附在第二压头5的第二吸附板51上。从而有利于避免出现因第二部分204与第二吸附板51之间出现错位,使得第二部分204与第一部分203之间的弯折部分的弯折半径较大,弯折后的待弯折部件的厚度较大的情况,或者第二部分204与第二压头5直接分离,第二压头5不能推动第二部分204翻转至第一部分203远离主体部分201的一侧的情况。
第二抽真空装置52还可以被配置为在第一压头3远离第一部分203的过程中,一直保持打开状态,使第二部分204的第二表面S2一直被吸附在第二压头5的第二吸附板51上,从而有利于防止因第一部分203向远离主体部分201的方向弹起导致第二部分204与第二吸附板51之间出现错位,第二压头5无法推动第二部分204翻转至第一部分203远离主体部分201的一侧的情况发生。
在一些示例中,第二抽真空装置52还可以被配置为在第二压头5拉动第 二部分204翻转至主体部分201的第一侧的过程中,和在第二压头5推动第二部分204翻转至第一部分203远离主体部分201的一侧的过程中,一直保持开启状态。
在另一些示例中,第二抽真空装置52还可以被配置为在第二压头5拉动第二部分204翻转至主体部分201的第一侧的过程中、在第二压头5推动第二部分204翻转至第一部分203远离主体部分201的一侧的过程中,和在第一压头3远离第一部分203的过程中,均一直保持开启状态。
在一些实施例中,如图8所示,第一压头3还包括第一压板33和第一气缸34。其中,第一气缸34与第一压板33连接,第一气缸34被配置为驱动第一压板33沿靠近或远离第一部分203的方向运动。
如图9所示,待弯折器件100还包括位于主体部分201的第一侧表面上的第一粘接层205。在第一压头3停止推动第一部分203、且第一压头3未向远离第一部分203的方向运动时,第一压板33位于第一部分203远离第一粘接层205的一侧,第一压板33在主体部分201上的正投影与第一粘接层205在主体部分201上的正投影至少部分重叠,第一气缸34被配置为驱动第一压板33向靠近第一部分203的方向运动,使第一部分203与主体部分201通过第一粘接层205粘接在一起。
这样设置,使得在第一压头3远离第一部分203之后,第一部分203不易出现向远离主体部分201的方向弹起的情况,第一部分203与主体部分201之间的距离可以较小,从而有效的减小了弯折后的待弯折器件的厚度。
在一些实施例中,如图8所示,第二压头5包括第二压板53和第二气缸54。其中,第二气缸54与第二压板53连接,第二气缸54被配置为驱动第二压板53沿靠近或远离第二部分204的方向运动。
其中,如图10所示,待弯折器件100还包括位于第二部分204的第一表面S1上的第二粘接层206,在第二压头5停止推动第二部分204、且第二压头5未向远离第二部分204的方向运动时,第二压板53位于第二部分204远离第二粘接层206的一侧,第二压板53在主体部分201上的正投影与第二粘接层206在主体部分201上的正投影至少部分重叠,第二气缸54被配置为驱动第二压板53向靠近第二部分204的方向运动,使第二部分204与第一部分203通过第二粘接层206粘接在一起。
这样设置,在第二压头5远离第二部分204之后,第二部分204不易出现向远离第一部分的方向弹起的情况,且第二部分204与第一部分203之间的间隙可以较小,从而有利于减小弯折后的待弯折器件的厚度。
在一些实施例中,如图1和图11所示,所述第一驱动机构2包括第一底座21、第一Y轴运动机构22、第一Z轴运动机构23、第一X轴旋转机构24和第一旋转臂25。其中,第一Y轴运动机构22设置于第一底座21上,第一Y轴运动机构22包括能够相对于第一底座21沿Y轴方向运动的第一支撑结构221。第一Z轴运动机构23设置于第一支撑结构221上,第一Z轴运动机构23包括能够相对于第一支撑结构221沿Z轴方向运动的第二支撑结构231。第一X轴旋转机构24设置于第二支撑结构231上,第一X轴旋转机构24包括能够相对于第二支撑结构231绕X轴转动的第一旋转结构241。第一旋转臂25的一端与第一旋转结构241相连,第一旋转臂25的另一端与第一压头5相连,第一旋转臂25平行于第一旋转结构241的旋转轴线O,且第一旋转臂25与第一旋转结构241的旋转轴线O之间具有第一预设间距d1。
其中,第一预设间距d1可以根据待弯折器件的大小进行调节。例如,当待弯折器件的尺寸较大时,第一预设间距d1的值可以较大,当待弯折尺寸较小时,第一预设间距d1的值可以较小。
示例性的,第一Y轴运动机构22还可以包括第一驱动电机和第一丝杆滑块机构。其中,第一驱动电机安装于第一底座21上。第一丝杆滑块机构包括第一丝杆和与第一丝杆螺纹连接的第一滑块,第一丝杆与第一驱动电机的输出轴相连,第一滑块安装于第一底座21的导轨上,且第一滑块与第一支撑结构221相连接,通过第一电机驱动第一丝杆转动,可以使第一滑块相对于第一丝杆沿Y轴方向运动,从而实现第一支撑结构221相对于第一底座21沿Y轴方向运动。
示例性的,第一Z轴运动机构23还可以包括第二驱动电机和第二丝杆滑块机构。其中,第二驱动电机安装于第一支撑结构231上。第二丝杆滑块机构包括第二丝杆和与第二丝杆螺纹连接的第二滑块,第二丝杆与第二驱动电机的输出轴相连,第二滑块安装于第一支撑结构221的导轨上,且第二滑块与第二支撑结构231相连,通过第二电机驱动第二丝杆转动,可以使第二滑块相对于第二丝杆沿Z轴方向运动,从而实现第二支撑结构231相对于第一支撑结构221沿Z轴方向运动。
示例性的,参见图1,第一X轴旋转机构24还可以包括与第一旋转结构241相连接的驱动电机242,驱动电机242被配置为驱动第一旋转结构241绕旋转轴线顺时针方向运动或逆时针方向运动。
这样,第一Y轴运动机构22,第一Z轴运动机构23,第一X轴旋转机构24和第一旋转臂25相互配合即可驱动第一压头3将第一部分203翻转至 主体部分201的第一侧。
需要说明的是,在第一驱动机构2驱动第一压头3推动第一部分203翻转至主体部分201的第一侧的过程中,第一Y轴运动机构22、第一Z轴运动机构23、第一X轴旋转机构24同时动作。示例性的,第一驱动机构2驱动第一压头3推动第一部分203翻转至主体部分201的第一侧的过程可以包括:第一Y轴运动机构22中第一支撑结构221沿Y轴运动,使第一压头3逐渐靠近主体部分201。第一Z轴运动机构23中的第二支撑结构231沿Z轴方向先向上运动再向下运动。第一X轴旋转机构24中的第一旋转结构241绕旋转轴线O旋转大约180度,从而带动第一旋转臂25绕旋转轴线O旋转大约180度,从而使第一压头3翻转至主体部分201的第一侧。
此外,利用第一Y轴运动机构42还能够在第一压头3停止推动第一部分203,且第一部分203与主体部分201平行或大致平行后,使第一压头3沿Y轴方向逐渐远离第一部分203。
在一些实施例中,如图1和图11所示,第二驱动机构4可以包括第二底座41、第二Y轴运动机构42、第二Z轴运动机构43、第二X轴旋转机构44和第二旋转臂45。其中,第二Y轴运动机构42设置于第二底座41上,第二Y轴运动机构42包括能够相对于第二底座41沿Y轴方向运动的第三支撑结构421。第二Z轴运动机构43设置于第三支撑机构421上,第二Z轴运动机构43包括能够相对于第三支撑结构421沿Z轴方向运动的第四支撑结构431。第二X轴旋转机构44设置于第四支撑结构431上,第二X轴旋转机构44包括能够相对于第四支撑结构431绕X轴转动的第二旋转结构441。第二旋转臂45,第二旋转臂45的一端与第二旋转结构441相连,第二旋转臂45的另一端与第二压头5相连,第二旋转臂45平行于第二旋转结构441的旋转轴线,且第二旋转臂45与第二旋转结构441的旋转轴线O1之间具有第二预设间距d2。
其中,第二预设间距d2的大小可以根据待弯折器件的大小相应设定。例如,当待弯折器件的尺寸较大时,第二预设间距d2的值可以较大,当待弯折尺寸较小时,第二预设间距d2的值可以较小。
示例性的,第二Y轴运动结构42还可以包括第三驱动电机,和第三丝杆滑块机构,其中,第三驱动电机安装于第二底座上。第三丝杆滑块机构包括第三丝杆和与第三丝杆螺纹连接的第三滑块,第三丝杆与第三驱动电机的输出轴相连,第三滑块安装于第二底座42的导轨上,且第三滑块与第三支撑结构相连接,通过第三电机驱动第三丝杆转动,可以使第三滑块向对于第三丝 杆沿Y轴方向运动,从而实现第三支撑结构421相对于第二底座21沿Y轴方向运动。
示例性的,第二Z轴运动机构43还可以包括第四驱动电机和第四丝杆滑块机构,其中,第四驱动电机安装于第三支撑结构421上,第四丝杆滑块机构包括第四丝杆和与第四丝杆螺纹连接的第四滑块,第四丝杆与第四驱动电机的输出轴相连,第四滑块安装于第三支撑结构421的导轨上,且第四滑块与第四支撑结构431相连,通过第四电机驱动第四丝杆转动,可以使第四滑块相对于第四丝杆沿Z轴方向运动,从而实现第四支撑结构431相对于第三支撑结构沿Z轴方向运动。
示例性的,第二X轴旋转机构44还可以包括与第二旋转结构441相连接的驱动电机,驱动电机带动第二旋转结构441绕旋转轴线顺时针方向运动或逆时针方向运动。
通过这样设置,利用第二Y轴运动机构42,第二Z轴运动机构43,第二X轴旋转机构44和第二旋转臂45即可驱动第二压头5工作,使得第二压头5能够拉动第二部分204翻转至主体部分201的第一侧,推动第二部分204翻转至第一部分203远离主体部分201的一侧。
需要说明的是,在第二驱动机构4驱动第二压头5拉动第二部分204翻转至主体部分201的第一侧的过程中,第二Y轴运动机构42、第二Z轴运动机构43和第二X轴旋转机构44同时动作。示例性的,第二压头5拉动第二部分204翻转至主体部分201的第一侧的过程中:第二Y轴运动机构42中第三支撑结构421相对于第二底座41沿Y轴方向运动,使得第二压头5在Y轴方向上逐渐靠近主体部分201;第二Z轴运动机构43中的第四支撑结构431相对于第三支撑结构421向上运动;第二X轴旋转机构44中的第二旋转结构441绕旋转轴线O1旋转90度,使得第二压头5翻转至主体部分201的第一侧。
同理,在第二驱动机构4驱动第二压头5推动第二部分204翻转至第一部分203远离主体部分201的一侧的过程中,第二Y轴运动机构42、第二Z轴运动机构43和第二X轴旋转机构44也同时动作。示例性的,第二压头5推动第二部分204翻转至第一部分203远离主体部分201的一侧的过程中:第二Y轴运动机构42中的第三支撑结构421相对于第二底座41沿Y轴方向运动,使得第二压头5向靠近第一部分203的方向运动;第二Z轴运动机构43中的第四支撑结构431相对于第三支撑结构421先向上运动再向下运动;第二X轴旋转机构44中的第二旋转结构441绕旋转轴线O1旋转90度,使 得第二压头5翻转至第一部分203远离主体部分201的一侧。
在一些实施例中,如图1所示,第一旋转结构241与第二旋转结构441分别位于固定结构1沿X轴长度方向的相对两侧,第一旋转臂25向第二旋转结构441靠近固定结构1的一侧延伸,第二旋转臂45向第一旋转结构241靠近固定结构1的一侧延伸。
这样,一方面能够使第一旋转臂25和第二旋转臂45的长度均较短,第一旋转臂25与第一旋转结构241连接的一端和第一旋转臂25与第一压头3连接的一端在Z轴方向上的高度差异较小,第二旋转臂45与第二旋转结构441连接的一端和第一旋转臂45与第二压头5连接的一端在Z轴方向上的高度差异也较小,从而有利于提高第一压头3和第二压头5运动过程中Z轴方向上的高度的控制精度。
另一方面,将第一旋转结构241和第二旋转结构441分别设置在固定结构1的两侧,还能使得在第一次弯折过程(即,第一压头3推动第一部分203翻转至主体部分201的第一侧,同时,第二压头5拉动第二部分204翻转至主体部分201的第一侧)中,第一压头3与第二压头5同时运动,且不容易使第一压头3与第二压头5之间,或第一旋转臂25与第二旋转臂45之间,出现碰撞,避免弯折设备100在工作过程出现故障。
在一些实施例中,如图1所示,X轴,Y轴,Z轴三者相互垂直,且X轴与Y轴均平行于水平面。
在一些实施例中,如图12所示,固定结构1包括载板11和第三抽真空装置12。其中,载板11上设置有多个抽真空孔111。第三抽真空装置12与多个抽真空孔111连通。
其中,本公开对载板11的形状和大小不作限定,只要保证载板11能够支撑待弯折器件200的主体部分201即可。示例性的,参见图12,载板11在水平面上的正投影可以是矩形。
本公开对载板11上设置的抽真空孔111的数量、大小,形状,以及分布情况也不做限定,只要抽真空孔111能够与待弯折器件200的主体部分201相接触,并能够在第三抽真空装置12的作用下,吸附待弯折器件200的主体部分201即可。示例性的,如图12所示,抽真空孔111在水平面上的正投影可以是圆形。
这样,载板11上设置多个抽真空孔111,第三抽真空装置12与多个抽真空孔111相连,使得在弯折设备100对待弯折器件200进行弯折时,通过打开第三抽真空装置12即可将待弯折器件200的主体部分201吸附在载板11 上,避免了弯折过程中主体部分201与载板11之间发生相对运动,使得待弯折器件200与载板之间摩擦,导致待弯折器件被破坏情况发生。同时,在弯折过程中将主体部分201固定至载板11上,还能够有利于弯折设备100对待弯折器件200进行弯折。
示例性的,固定结构1还可以包括设置在载板上的隔离膜,隔离膜完全覆盖载板11。这样,当待弯折器件200的尺寸较小时,可以将较小面积的隔离膜去除,以暴露出小部分抽真空孔111,从而使固定结构1能够吸附较小尺寸的待弯折器件200。当待弯折器件200的尺寸较大时,可以将较大面积的隔离膜去除,以暴露出较多的抽真空孔111,从而吸附较大尺寸的待弯折器件200。通过这样设置,使得固定结构1能够固定多种不同尺寸的待弯折器件200,提高了弯折设备100的使用的灵活性。
在一些实施例中,如图1所示,弯折设备100还包括第三驱动机构6。第三驱动机构6包括第三底座61和第三Y轴运动机构62。其中,第三Y轴运动机构62设置于第三底座61上。第三Y轴运动机构62包括能够相对于第三底座61沿Y轴方向运动的第五支撑结构621,载板11设置于第五支撑结构621上。这样设置使得载板11能够与第五支撑机构621一起相对于第三底座61沿Y轴方向运动。
在基础上,在利用弯折设备100对待弯折器件200进行加工前,可以先对载板11与待弯折器件200进行对位,以使待弯折器件200的主体部分201覆盖载板11的指定位置,从而便于第一驱动机构2驱动第一压头3运动至第一部分203的第一表面S1上,第二驱动机构4驱动第二压头5运动至第二部分204的第二表面S2上。
示例性的,载板11与待弯折器件200进行对位的过程可以是:在弯折设备100对待弯折器件200进行弯折前,利用第三驱动机构6将载板11传输至第一位置处,将待弯折器件200放置在载板11上,并对其进行初步对位,使其在载板11上的正投影与指定位置大致重叠。随后,利用第三驱动机构6将载板11传输第二位置处,利用CCD(charge coupled device,电荷耦合器件)相机实现待弯折器件200的主体部分201与载板11的精确对位。其中,沿X轴方向,第一位置到第一驱动机构2的距离大于第二位置到第一驱动机构2的距离,第一位置到第二驱动机构4的距离同样大于第二位置到第二驱动机构4的距离。
在一些实施例中,如图13所示,弯折设备100还包括至少一个风机7,设置于第三底座61上,至少一个风机7被配置为在第一压头3运动至第一部 分203的第一表面且第二压头5运动至第二部分204的第二表面之前,向待弯折部分202吹风,使待弯折部分202和主体部分201位于同一平面或大致位于同一平面内。
通过这样设置,第一压头3和第二压头5能够分别与第一部分203的第一表面S1、第二部分204的第二表面S2较好的接触,避免在第一压头3与第一部分201的第一表面S1接触时,第一压头3划伤第一表面S1,对第一表面S1上设置的器件或电路结构造成破坏,同时使得第二压头5与第二部分204的第二表面S2的接触面积较大,避免因接触面积过小,第二压头5不能较好的吸附第二部分204的第二表面S2,使得弯折过程中第二部分204与第二压头5分离,第二部分204与主体部分201直接接触的情况发生。
其中,本公开各个实施例中对风机7的数量不做限定,只要能够使待弯折部分202与主体部分201位于同一平面或大致位于同于平面内即可。其中,“大致位于同一平面内”可以是指待弯折部分202所在的平面与主体部分201所在的平面之间存在一个较小的夹角,该夹角不超过10度。
在另一些实施例中,如图14所示,弯折设备100还可以包括至少一个支撑杆8。支撑杆8与载板11相连,至少一个支撑杆8被配置为在第一压头3运动至第一部分203的第一表面S1且第二压头5运动至第二部分204的第二表面S2之前,支撑待弯折部分202,使待弯折部分202和主体部分201位于同一平面或大致位于同一平面内。
通过这样设置,使得第一压头3和第二压头5能够分别与第一部分203的第一表面、第二部分204的第二表面较好的接触,防止在第一压头3与第一部分203的第一表面S1接触时,第一压头3划伤第一表面S1,对第一表面上设置的器件或电路结构造成破坏。同时有利于避免第二压头5与第二部分204的第二表面S2接触面积过小,使得第二压头5不能够很好的吸附第二部分204的第二表面S2,使得弯折过程中第二部分204与第二压头5分离,第二部分204与主体部分201直接接触的情况发生。
其中,本公开各个实施例中对支撑杆8的数量不做限定,只要能够使待弯折部分202与主体部分201位于同一平面或大致位于同一平面内即可。其中,“大致位于同一平面内”可以是指待弯折部分202所在的平面与主体部分201所在的平面之间存在一个较小的夹角,该夹角不超过10度。
在又一些实施例中,弯折设备100也可以同时包括至少一个风机7和至少一个支撑杆8。通过这样设置,能够更好的使待弯折部分202和主体部分201位于同一平面或大致位于同一平面内,从而便于第一压头3与第一部分 203的第一表面S1接触,第二压头5与第二部分204的第二表面S2接触。
本公开的一些实施例还提供了一种待弯折器件200,如图15所示,待弯折器件为待弯折的显示模组300。待弯折的显示模组300包括显示面板301,覆晶薄膜电路板302、印刷电路板303、柔性电路板304和时钟控制电路板305。其中,覆晶薄膜电路板302的一端绑定于显示面板301上。印刷电路板303的一端与覆晶薄膜电路板302的另一端绑定连接。柔性电路板304的一端绑定于印刷电路板303的另一端。时钟控制电路板305的一端与柔性电路板304的另一端绑定连接。
需要说明的是,显示面板301为待弯折器件200的主体部分201,印刷电路板303为待弯折器件200的第一部分203,柔性电路板304为待弯折器件200的第二部分204。
示例性的,显示面板301可以是液晶显示面板(Liquid Crystal Display,简称LCD),有机电致发光显示面板(Organic Light-Emitting Diode,简称OLED)或量子点电致发光显示面板(Quantum Dot Light Emitting Diodes,简称QLED)等。
本公开一些实施例所提供的待弯折器件200为待弯折的显示模组300,显示模组300中的时钟控制电路板305的一端绑定至柔性电路板304远离印刷电路板303的一端,与相关技术中将时钟控制电路板设置在印刷电路板上相比,本公开一些实施例所提供的待弯折器件200在两次弯折后,厚度较小。
在一些实施例中,如图15所示,显示模组300还可以包括设置在显示面板301第一侧表面上的第一填充层306以及位于柔性电路板304第二表面上的第二填充层307。其中,第一填充层306为待弯折器件200的第一粘接层205,第二填充层307为待弯折器件的第二粘接层206。
第一填充层306用于在待弯折的显示模组被弯折过程中将印刷电路板303(也即第一部分203)与显示面板(也即主体部分201)粘接在一起。第二填充层307用于在弯折过程中,将印刷电路板303(也即第一部分203)与柔性电路板304(也即第二部分204)粘接在一起。
通过设置第一填充层306和第二填充层307使得印刷电路板303能够固定在显示面板301上,柔性电路板304能够固定在印刷电路板303上,避免弯折后印刷电路板303和柔性电路板304向远离显示面板的方向弹起。另一方面,设置第一填充层306和第二填充层307还能够使弯折后的显示模组中,印刷电路板303与显示面板301之间的间距较小,柔性电路板304与印刷电路板303之间的间距较小,有利于减小弯折后的显示模组的厚度。
本公开的一些实施例提供了一种采用弯折设备100对待弯折器件200进行加工的加工方法。如图16所示,该方法包括:
S1、弯折设备100的固定结构1固定待弯折器件200的主体部分201。
S2、弯折设备100的第一驱动机构2驱动第一压头3运动至第一部分203的第一表面S1上,弯折设备100的第二驱动机构4驱动第二压头5运动至第二部分204的第二表面S2上;其中,第二表面S2与第一表面S1分别位于待弯折部分202的两侧。
S3、第一驱动机构2驱动第一压头3推动第一部分203翻转至主体部分201的第一侧,使第一部分203与主体部分201平行或大致平行。同时,第二驱动机构4驱动第二压头5拉动第二部分204翻转至主体部分201的第一侧。
利用本公开一些实施例提供的加工方法,通过第一驱动机构2驱动第一压头3推动第一部分203翻转至主体部分201的第一侧,使第一部分203与主体部分201平行或大致平行。通过第二驱动机构4在第一压头3推动第一部分203的同时,驱动第二压头5拉动第二部分204翻转至主体部分201的第一侧。由于第二压头5与第一压头3同时动作,且第二压头5与第二部分204的第二表面S2相接触,因此在第一部分203与主体部分201平行或大致平行,且第二部分204翻转至主体部分201的第一侧时,待弯折部分202中位于第一部分203远离主体部分201一侧的部分均不容易与主体部分201相接触,从而使得弯折设备100在后续对待弯折器件200弯折的过程中,能够将待弯折部分202的第二部分204翻转至第一部分203远离主体部分201的一侧,也即实现对待弯折器件200的两次弯折。
在一些实施例中,如图17所示,该加工的方法还包括:
S4、第一驱动机构2驱动第一压头3向远离第一部分203的方向运动;
S5、在第一压头3远离第一部分203后,第二驱动机构4推动第二部分204翻转至第一部分203远离主体部分201的一侧,使第二部分204与第一部分203平行或大致平行。
在一些实施例中,如图9所示,待弯折器件200还包括位于主体部分的第一侧表面上的第一粘接层205。基于此,参见图18,加工方法还包括:
S31、在第一压头3停止推动第一部分203之后,远离第一部分203的第一表面之前,第一压头3按压第一部分203,使第一部分203与主体部分201粘接在一起。
