为使本申请的上述目的、特征和优点能够更加明显易懂,下面结合附图对本申请的具体实施方式做详细的说明。在下面的描述中阐述了很多具体细节以便于充分理解本申请。但是本申请能够以很多不同于在此描述的其它方式来实施,本领域技术人员可以在不违背本申请内涵的情况下做类似改进,因此本申请不受下面公开的具体实施例的限制。
请参见图1和图2,其中示出了本申请一实施方式的异形曲面盖板与柔性屏的贴合装置200,用于将柔性屏2贴合到异形曲面盖板3内侧。其中,异形曲面盖板3包括呈平面状的平直区31、以及位于平直区31两侧且与平直区31平滑过渡的弧钩区33。换言之,平直区31位于中间位置,两侧各有一个向回弯折形成的弧钩区33。优选地,本实施方式中,弧钩区33呈与平直区31相切的半圆状。
异形曲面盖板与柔性屏的贴合装置200包括用于压贴柔性屏2的一侧的第一贴合体210、用于压贴柔性屏2的另一侧的第二贴合体220、用于压贴异形曲面盖板3的平直区31的中部的压贴体230以及驱动机构240。
其中,第一贴合体210的外围具有第一压贴壁211。第一压贴壁211包括与异形曲面盖板3中弧钩区33内表面形状适配的第一贴弯壁214,以及与第一贴弯壁214连续设置、且对应于异形曲面盖板3中部分平直区31的第一贴平壁212。优选地,第一贴平壁212与第一贴弯壁214平滑过渡。
具体地,第一贴平壁212呈平面状,第一贴弯壁214呈与弧钩区33匹配的半圆状。即, 在第一贴弯壁214上贴附柔性屏2后,恰能与弧钩区33贴压。换言之,第一贴弯壁214的半径与弧钩区33内壁的半径之差为柔性屏2的厚度。
其中,第二贴合体220的外围具有第二压贴壁221。第二压贴壁221包括与异形曲面盖板3中弧钩区33内表面形状适配的第二贴弯壁224,以及与第二贴弯壁224连续设置、且对应于异形曲面盖板3中部分平直区31的第二贴平壁222。优选地,第二贴平壁222与第二贴弯壁224平滑过渡。
具体地,第二贴平壁222呈平面状,第二贴弯壁224呈与弧钩区33匹配的半圆状。即第二贴弯壁224的结构与第一贴弯壁114结构相同,且第二贴弯壁224与第一贴弯壁214相对设置。当然,在平直区31两侧的弧钩区33的结构不同时,第二贴弯壁224与第一贴弯壁214的结构需做相应调整。
其中,压贴体230位于第一贴合体210与第二贴合体220之间,且压贴体230的外围具有用于压贴异形曲面盖板3的平直区31中部的第三贴平壁231。具体地,第三贴平壁231呈平面状。
其中,驱动机构240用以驱动第一贴合体210与第二贴合体220移动,以使第一贴合体210与第二贴合体220邻接或者远离压贴体230。
具体地,当第一贴合体210与第二贴合体220邻接压贴体230时,第一贴平壁212、第三贴平壁231与第二贴平壁222依次邻接,且三者共面,即,第一贴平壁212、第三贴平壁231与第二贴平壁222位于同一个平面上。
在前述实施方式的基础上,第一贴合体210与第二贴合体220呈对称设置。这样有利于同时对柔性屏2上处于对称位置的部分进行压贴,提高压贴效果。
在前述实施方式的基础上,压贴体230的内部具有用于容纳驱动机构240的空腔232,驱动机构240位于空腔232内。
更优地,驱动机构240包括相对设置的用于驱动第一贴合体210移动的第一驱动组件241、以及用于驱动第二贴合体220移动的第二驱动组件242。
其中,第一驱动组件241包括第一连杆243和第一驱动杆244。第一驱动杆244垂直于第三贴平壁231、并相对于第一贴合体210可往返运动地设置在压贴体230内部的空腔中,第一驱动杆244与第一连杆243垂直连接。
本实施方式中,第一连杆243垂直固定于第一驱动杆244的中间位置。当然,还可以将 第一连杆243垂直固定于第一驱动杆244的其他位置,例如,固定于第一驱动杆244的上端或者下端。本实施方式中,第一连杆243与第一驱动杆244为焊接连接。当然,第一连杆243与第一驱动杆244也可以为一体成型,或者还可以通过其他方式实现第一连杆243与第一驱动杆244的相对固定。
其中,第二驱动组件242包括第二连杆245和第二驱动杆246。第二驱动杆246垂直于第三贴平壁231、并相对于第二贴合体220可往返运动地设置在压贴体230内部的空腔中,第二驱动杆246与第二连杆245垂直连接。
本实施方式中,第二连杆245垂直固定于第二驱动杆246的中间位置。当然,还可以将第二连杆245垂直固定于第二驱动杆246的其他位置,例如,固定于第二驱动杆246的上端或者下端。本实施方式中,第二连杆245与第二驱动杆246为焊接连接。当然,第二连杆245与第二驱动杆246也可以为一体成型,或者还可以通过其他方式实现第二连杆245与第二驱动杆246的相对固定。
通过第一驱动组件241与第二驱动组件242的左右移动驱使第一贴合体210和第二贴合体220分别沿左右方向移动。具体地,第一驱动组件241与第二驱动组件242向远离压贴体230的方向移动时,第一贴合体210和第二贴合体220分别向两侧移动;第一驱动组件241与第二驱动组件242向靠近压贴体230的方向移动时,第一贴合体210和第二贴合体220均向中间移动,以靠近压贴体230。
优选地,第一驱动组件241和第二驱动组件242对称设置。这样有利于对柔性屏2上处于对称位置的部位施加相同的压力,以提高贴合效果。
需要说明的是,驱动机构240不限于此,还可以通过其他方式分别控制第一贴合体210和第二贴合体220的移动等。
在前述实施方式的基础上,异形曲面盖板与柔性屏的贴合装置200还包括用以控制驱动机构240沿靠近或者远离弧钩区33的方向移动的气缸250。气缸250可以有效控制驱动机构240左右移动的速度和时间,节省人力。
在前述实施方式的基础上,第一压贴壁211、第二压贴壁221与第三贴平壁231上均设有若干个真空吸附孔(未图示)。从而可以通过真空吸附的方式将柔性屏2吸附在第一贴合体210和第二贴合体220上。当然,可以采用其他方式将柔性屏2贴附在第一贴合体210和第二贴合体220上。例如,在柔性屏2两端均粘结弹性胶带,并将弹性胶带的另一端分别固定 于对应侧的第一贴合体210和第二贴合体220上。
在前述实施方式的基础上,第一贴合体210、第二贴合体220与压贴体230的内部均具有用以吸附柔性屏2的真空腔。
异形曲面盖板与柔性屏的贴合装置200还包括用于连通压贴体230与第一贴合体210内部的真空腔的第一伸缩连接件260、以及用于连通压贴体230与第二贴合体内部的真空腔的第二伸缩连接件270。
其中,第一伸缩连接件260的两端分别固定于压贴体230与第一贴合体210上,且可被压缩至使得压贴体230与第一贴合体210邻接。具体地,可以通过粘接或者铆钉实现第一伸缩连接件260两端的固定。当然,还可以采用其他固定方式。
此外,压贴体230与第一贴合体210邻接,指的是压贴体230与第一贴合体210的距离很近,包括但不限于二者衔接共面,二者之间仍可以存在一定的间隙。
其中,第二伸缩连接件270的两端分别固定于压贴体230与第二贴合体220上,且可被压缩至使得压贴体230与第二贴合体220邻接。具体地,可以通过粘接或者铆钉实现第二伸缩连接件270两端的固定。当然,还可以采用其他固定方式。
此外,压贴体230与第二贴合体220邻接,指的是压贴体230与第二贴合体220的距离很近,包括但不限于二者衔接共面,二者之间仍可以存在一定的间隙。
本实施方式中,第一伸缩连接件260与第二伸缩连接件270被压缩后,压贴体230与第一贴合体210或者第二贴合体220之间仍存在一定的间隙。为了减小上述间隙的尺寸,可以分别在压贴体230分别与第一贴合体210、第二贴合体220相对的两端面上开设分别用于容纳第一伸缩连接件260与第二伸缩连接件270的凹槽,或者在第一贴合体210、第二贴合体220分别与压贴体230相对的端面上开设分别用于容纳第一伸缩连接件260与第二伸缩连接件270的凹槽。这样,当第一伸缩连接件260与第二伸缩连接件270被压缩之后,可以被收纳至上述凹槽内,而压贴体230分别与第一贴合体210、第二贴合体220可实现衔接共面,从而充分压贴柔性屏2。
此外,本实施方式中,由于压贴体230与第一贴合体210或者第二贴合体220内部的真空腔通过第一伸缩连接件260与第二伸缩连接件270实现相互连通,因此,只需设置一个真空吸附装置即可实现同时控制第一贴合体210、第二贴合体220与压贴体230内部的真空度。
当然,还可以分别控制第一贴合体210、第二贴合体220与压贴体230内的真空腔的真 空度。此时,可设置多个分别控制第一贴合体210、第二贴合体220与压贴体230的真空吸附装置。
在前述实施方式的基础上,第一伸缩连接件260与第二伸缩连接件270均为橡胶波纹管。当然,二者不限于此,还可以为能够起到伸缩作用的、能够连通压贴体230与第一贴合体210或者第二贴合体220的其他伸缩件。
此外需要说明的是,本申请的驱动机构不限于此,还可以为能够起到驱动第一贴合体210与第二贴合体220移动、以使第一贴合体210与第二贴合体220邻接或者远离压贴体230的其他机构。
在另一个实施方式中,驱动机构240包括两个膨胀体(未图示)以及向膨胀体充气的气源。气源位于膨胀体的一侧。其中,上述两个膨胀体分别位于第一贴合体210、第二贴合体220与压贴体230之间,且分别连接第一贴合体210与压贴体、第二贴合体220与压贴体230。且上述两个膨胀体的内部封闭,分别与第一贴合体210、第二贴合体220、压贴体230之间相互独立。
当向膨胀体充气时,膨胀体的体积增大,能够推动第一贴合体210与第二贴合体220沿远离压贴体230的方向移动,以压贴柔性屏2。
优选地,膨胀体为橡胶气囊。橡胶气囊的弹性较好,膨胀之后能够对第一贴合体210和第二贴合体220施加较大的压力,以推动第一贴合体210和第二贴合体220移动。在实际操作中该膨胀体即为前述提及的第一伸缩连接件260与第二伸缩连接件270;此时第一伸缩连接件260与第二伸缩连接件270同时实现驱动功能与气相连通压贴体230、第一贴合体210、以及第二贴合体220的作用。
在另一个实施方式中,驱动机构240包括弹性伸缩体(未图示)以及用于驱动弹性伸缩体伸缩的动力源。本实施方式的弹性伸缩体与第一贴合体210、第二贴合体220、压贴体230之间相互独立。
优选地,弹性伸缩体为弹簧。当压缩弹簧时,第一贴合体210、第二贴合体220分别靠近压贴体230;当压缩弹簧的力被释放之后,压缩弹簧可推动第一贴合体210与第二贴合体220沿远离压贴体230的方向移动,以压贴柔性屏2。此外,还可以缓慢释放对压缩弹簧的压缩力,以缓慢压贴柔性屏2。
此外,第一贴合体210、第二贴合体220、压贴体230以及驱动机构240的材质优选为铝 合金,以保证足够的强度来压贴柔性屏2;优选地,第一贴合体210、第二贴合体220、压贴体230以及驱动机构240的表面形成有柔性缓冲层,以便于更好的保护柔性屏2的表面。
上述异形曲面盖板3与柔性屏2的贴合装置200,第一贴合体210的第一贴平壁212、第二贴合体220的第二贴平壁222以及压贴体230的第三贴平壁231共同用于压贴异形曲面盖板3的平直区31;第一贴合体210的第一贴弯壁214与第二贴合体220的第二贴弯壁224用于压贴异形曲面盖板3的弧钩区33。通过驱动机构240驱动第一贴合体210与第二贴合体220移动,以使第一贴合体210与第二贴合体220邻接或者远离压贴体230,以充分对异形曲面盖板3与柔性屏2进行贴附,进一步提高贴合效果。
请参见图3,其中示出了一实施方式的异形曲面盖板与柔性屏的贴合方法,包括如下步骤:
S10、请一并参见图1和图2,提供柔性屏2、异形曲面盖板3、以及上述的异形曲面盖板与柔性屏的贴合装置200;异形曲面盖板3包括平直区31、以及位于平直区31两侧且与平直区31平滑过渡的弧钩区33。
其中,柔性屏2优选为柔性OLED屏。当然,可以理解的是,柔性屏2还可以是其它柔性屏。
当然,还可以提供用于贴合柔性屏2与异形曲面盖板3的贴合胶层。贴合胶层用于将柔性屏2和异形曲面盖板3贴合,故可以预贴在柔性屏2上,也可以预贴在异形曲面盖板3上。
贴合胶层优选为OCA胶层。当然,可以理解的是,贴合胶层亦可以选自其它适用的贴合胶,例如SCA胶层。
S20、将柔性屏2贴附在第一贴合体210、压贴体230与第二贴合体220的外侧,得到初装体300,如图4所示。
较优地,第一压贴壁211、第二压贴壁221与第三贴平壁231上均设有若干个真空吸附孔;将柔性屏2贴附在第一贴合体210、压贴体230与第二贴合体220的外侧的操作为:采用真空吸附的方式将柔性屏2贴附在第一贴合体210、压贴体230与第二贴合体220的外侧。优选地,真空吸附的吸附压力为-60kpa至-80kpa,更优选为-80kpa。
此时,第一伸缩连接件260与第二伸缩连接件270均处于被压缩的状态。
S30、将初装体300插入异形曲面盖板3的内侧,并下压初装体300,完成部分异形曲面盖板3的平直区31与柔性屏2的贴合,如图5所示。
此时,第一伸缩连接件260与第二伸缩连接件270仍然保持被压缩的状态。
S40、驱动驱动机构240,以驱使第一贴合体210和第二贴合体220分别向靠近弧钩区33的方向移动,直至完成异形曲面盖板3与柔性屏2的贴合,如图6所示。
较优地,异形曲面盖板与柔性屏的贴合装置200还包括用以控制驱动机构240沿靠近或者远离弧钩区33的方向移动的气缸250。
较优地,驱动机构240包括相对设置的用于驱动第一贴合体210移动的第一驱动组件241、以及用于驱动第二贴合体220移动的第二驱动组件242。
其中,第一驱动组件241包括与第一贴合体210固定连接的第一连杆243、以及与第一连杆243垂直固定连接的第一驱动杆244。
其中,第二驱动组件242包括与第二贴合体220固定连接的第二连杆245、以及与第二连杆245垂直固定连接的第二驱动杆246。
在驱动驱动机构240,以驱使第一贴合体210和第二贴合体220分别向靠近弧钩区33的方向移动的操作中:气缸250驱动第一驱动杆244、第二驱动杆246向两侧移动;其中,第一驱动杆244移动时带动第一连杆243以及第一贴合体210向左侧移动,以使第一贴平壁212压贴异形曲面盖板3的平直区31一侧,之后第一贴弯壁214压贴异形曲面盖板3左侧的弧钩区33;同时,第二驱动杆246移动时带动第二连杆245以及第二贴合体220向右侧移动,以使第二贴平壁222压贴异形曲面盖板3的平直区31另一侧,之后第二贴弯壁224压贴异形曲面盖板3右侧的弧钩区33。
此外,在贴合的过程中,压贴体230的位置保持不动,第一伸缩连接件260与第二伸缩连接件270逐渐被拉伸,当完成异形曲面盖板3与柔性屏2的贴合之后,第一伸缩连接件260与第二伸缩连接件270的拉伸程度达到最大值。
较优地,驱动驱动机构240之前,还包括减弱真空吸附的吸附压力的步骤。优选地,减弱真空吸附的吸附压力后,吸附压力为-5kpa至-20kpa,优选为-10kpa。
上述异形曲面盖板3与柔性屏2的贴合方法,将初装体300插入异形曲面盖板3的内侧,避免柔性屏2的两端与异形曲面盖板3的两端产生干涉;另外,上述贴合方式,可以充分对异形曲面盖板3的弧钩区33进行贴附,进一步提高贴合效果。
以上所述实施例的各技术特征可以进行任意的组合,为使描述简洁,未对上述实施例中的各个技术特征所有可能的组合都进行描述,然而,只要这些技术特征的组合不存在矛盾, 都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本申请的几种实施方式,其描述较为具体和详细,但并不能因此而理解为对申请专利范围的限制。应当指出的是,对于本领域的普通技术人员来说,在不脱离本申请构思的前提下,还可以做出若干变形和改进,这些都属于本申请的保护范围。因此,本申请专利的保护范围应以所附权利要求为准。
