技术领域
本申请涉及柔性屏贴合设备技术领域，尤其涉及一种贴合装置及贴合方法。
背景技术
随着泛在屏时代的到来，人们对全面屏的需求也越来越强烈。为提高屏占比，双曲贴合技术及四曲贴合技术应运而生。
相关技术中主要利用柔性屏的柔性特性来实现全面屏。目前柔性屏的贴合方法主要是使用硅胶垫，将柔性屏压合到曲面盖板的内侧。在贴合过程中。因为曲面盖板平面区的贴合压力要大于其弯折区域的贴合压力，导致弯折区域贴合压力小，极易出现气泡，因此会导致曲面盖板和柔性屏之间贴合不良。
发明内容
本申请实施例提供一种贴合装置及贴合方法，旨在解决柔性屏和盖板的贴合过程中产生气泡的问题。
本申请第一方面的实施例提供了一种贴合装置，用于贴合曲面盖板和柔性屏，贴合装置包括：支撑件；形变承载件，包括相对设置的异形承载部及连接于异形承载部之间的形变部，形变部被支撑件支撑；柔性垫，设置于形变承载件背离支撑件的一侧，柔性垫包括用于支撑柔性屏的支撑面 和与形变部相配合的配合面，支撑面具有位于形变部背离支撑件一侧的脊柱段和位于脊柱段两侧的倾斜段；其中，形变部在沿贴合装置的高度方向上的力的作用下能够由第一状态变形至第二状态，以通过形变部的变形改变支撑面的形状，形变部在第一状态时，支撑面呈屋脊状，在形变部由第一状态转变至第二状态的过程中，倾斜段的倾斜度逐渐减小。
本申请第二方面的实施例还提供了一种贴合方法，使用上述的贴合装置贴合曲面盖板和柔性屏，方法包括：将柔性屏放置于柔性垫上，并使得形变部处于第一状态下；
将曲面盖板盖设于柔性屏上；
向曲面盖板施加压力，使得形变部由第一状态变形至第二状态，两个异形承载部沿相互远离的方向移动，曲面盖板和柔性屏由脊柱段对应的位置逐渐贴合。
在本申请实施例的贴合装置中，贴合装置包括支撑件、形变承载件和柔性垫。形变承载件包括异形承载部和形变部。柔性垫被支撑于形变承载件上，柔性垫具有用于承载柔性屏的支撑面，支撑面具有脊柱段和倾斜段。当贴合装置用于贴合柔性屏和曲面盖板时，柔性屏可以设置于支撑面上。
形变部在沿贴合装置的高度方向上的力的作用下能够由第一状态变形至第二状态，例如当曲面盖板向设置于支撑面的柔性屏提供压合力时，在支撑件和曲面盖板的挤压作用下，形变部能够由第一状态变形至第二状态，被支撑于形变部上的柔性垫的支撑面能够随着形变部的变形而变形。
在第一状态，支撑面呈屋脊状，曲面盖板和柔性屏在此状态下与柔性屏从中间部位开始贴合。在形变部由第一状态变形至第二状态的过程中，倾斜段的倾斜度逐渐减小，曲面盖板和柔性屏逐渐贴合。因此在本申请实施例提供的贴合装置中，能够令柔性屏与曲面盖板从中间部位开始接触，并从中间向两边逐渐压合，能够有效改善曲面盖板和柔性屏之间的贴合气泡，提高产品良率。

具体实施方式
下面将详细描述本申请的各个方面的特征和示例性实施例。在下面的详细描述中，提出了许多具体细节，以便提供对本申请的全面理解。但是，对于本领域技术人员来说很明显的是，本申请可以在不需要这些具体细节中的一些细节的情况下实施。下面对实施例的描述仅仅是为了通过示出本申请的示例来提供对本申请的更好的理解。在附图和下面的描述中，至少 部分的公知结构和技术没有被示出，以便避免对本申请造成不必要的模糊；并且，为了清晰，可能夸大了部分结构的尺寸。此外，下文中所描述的特征、结构或特性可以以任何合适的方式结合在一个或更多实施例中。
随着泛在屏时代的到来，人们对全面屏的需求也越来越强烈。为提高屏占比，双曲贴合技术及四曲贴合技术应运而生。但是目前曲面贴合存在良率较低的问题。
如图1所示，相关技术中，通常使用柔性硅胶基底30来实现曲面盖板10和柔性屏20的相互贴合。曲面盖板10包括弯曲部12及平面部11，通常的曲面盖板10包括在其宽度方向上相对设置的两个弯曲部12，平面部11连接于两个弯曲部12之间。弯曲部12具有较大的曲率，平面部11通常呈平面状。
相关技术中的柔性硅胶基底30包括承载面，承载面和曲面盖板10的形状相适配。在曲面盖板10和柔性屏20的贴合过程中，首先将柔性屏20放置于承载面，然后将曲面盖板10压合于柔性屏20上。
但是上述相关技术中，由于曲面盖板10的平面部11的贴合压力要大于其弯曲部12的贴合压力，导致弯曲部12极易出现贴合气泡，且容易出现贴合反弹风险，导致曲面盖板10和柔性屏20贴合不良。且当两个弯曲部12之间的最小间距小于曲面盖板10的宽度，即曲面盖板10的开口较小时，会导致曲面盖板10和柔性屏20无法贴合。
为了解决上述技术问题，提出本申请。为了更好地理解本申请，下面结合图2至图14对本申请实施例的贴合装置及贴合方法进行详细描述。
请一并参阅图2和图3，图2为本申请第一方面实施例提供的一种贴合装置1的结构示意图，图3是本申请第一方面实施例提供的一种贴合装置1的主视图。
本申请实施例的贴合装置1用于贴合曲面盖板10和柔性屏20，贴合装置1包括：支撑件100；形变承载件200，包括相对设置的异形承载部220及连接于异形承载部220之间的形变部210，形变部210被支撑件100支撑；柔性垫300，设置于形变承载件200背离支撑件100的一侧，柔性垫300包括用于支撑柔性屏20的支撑面310和与形变部210相配合的配合面 320，支撑面310具有位于形变部210背离支撑件100一侧的脊柱段311和位于脊柱段311两侧的倾斜段312；其中，形变部210在沿贴合装置1的高度方向上的力的作用下能够由第一状态变形至第二状态，以通过形变部210的变形改变支撑面310的形状，形变部210在第一状态时，支撑面310呈屋脊状，在形变部210由第一状态转变至第二状态的过程中，倾斜段312的倾斜度逐渐减小。
在本申请中，当形变部210处于第一状态时，支撑面310呈屋脊状，那么形变部210上沿Y方向相对的两端之间的间距较小，形变部210在Z方向上的尺寸较大。当形变部210处于第二状态时，倾斜段312的倾斜度逐渐减小，支撑面310由屋脊状逐渐展平，那么形变部210上沿Y方向相对的两端之间的间距逐渐变大，形变部210在Z方向上的尺寸逐渐减小。
倾斜段312的倾斜度逐渐减小是指倾斜段312与水平方向的夹角逐渐减小。当倾斜段312的倾斜度逐渐减小时，支撑面310由弯折状态向展平状态转变。
可选的，在贴合装置1的使用过程中，柔性屏20和曲面盖板10相互贴合时，曲面盖板10向位于柔性垫300的柔性屏20提供在高度方向上的压合力。
在本申请实施例的贴合装置1中，贴合装置1包括支撑件100、形变承载件200和柔性垫300。形变承载件200包括异形承载部220和形变部210。柔性垫300被支撑于形变承载件200上，柔性垫300具有用于承载柔性屏20的支撑面310，支撑面310具有脊柱段311和倾斜段312。当贴合装置1用于贴合柔性屏20和曲面盖板10时，柔性屏20可以设置于支撑面310上。
形变部210在沿贴合装置1的高度方向上的力的作用下能够由第一状态变形至第二状态，例如当曲面盖板10向设置于支撑面310的柔性屏20提供压合力时，在支撑件100和曲面盖板10的挤压作用下，形变部210能够由第一状态变形至第二状态，被支撑于形变部210上的柔性垫300的支撑面310能够随着形变部210的变形而变形。
在第一状态，支撑面310呈屋脊状，曲面盖板10和柔性屏20在此状态下与柔性屏20从中间部位开始贴合。在形变部210由第一状态变形至第 二状态的过程中，倾斜段312的倾斜度逐渐减小，曲面盖板10和柔性屏20逐渐贴合。因此在本申请实施例提供的贴合装置1中，能够令柔性屏20与曲面盖板10从中间部位开始接触，并从中间向两边逐渐压合，能够有效改善曲面盖板10和柔性屏20之间的贴合气泡，提高产品良率。
此外，在本申请实施例的贴合装置1中，形变部210在由第一状态移动至第二状态时，倾斜段312倾斜度逐渐减小，形变承载件200和柔性垫300在Y方向上的尺寸逐渐增大。曲面盖板10的两个弯曲部12相对围合形成曲面盖板10的开口。当曲面盖板10上弯曲部12的弯折角度较大，使得曲面盖板10上两个弯曲部12之间的最小尺寸小于其平面部11的尺寸时，即曲面盖板10的开口尺寸小于其宽度时，曲面盖板10依然能够扣合于柔性垫300的支撑面310上，并使得柔性屏20和曲面盖板10由内而外逐渐压合。
第一状态和第二状态的设置方式有多种，请一并参阅图4和图5，图4是本申请第一方面实施例提供的一种贴合装置1在第一状态下的主视图，图5是本申请第一方面实施例提供的一种贴合装置1在第二状态下的结构示意图。形变承载件200的形变部210由第一状态变形至第二状态的过程中，倾斜段312由图4中的倾斜状转变为图5中的平面状。
可选的，第一状态例如为形变部210在自然状态，即形变承载件200处于自然状态下，形变部210处于第一状态。第二状态为形变部210受力发生变形的状态，即形变承载件200受力时，形变部210变形处于第二状态。在这些可选的实施例中，当形变部210处于自然状态下时，可以将柔性屏20设置于形变部210，柔性屏20和曲面盖板10由中间部位开始贴合。贴合过程中，形变部210变形至第二状态，令柔性屏20和曲面盖板10从中间向两边逐渐贴合。
在其他一些可选的实施例中，第一状态还可以为形变部210的受力状态，第二状态为形变部210的自然状态，或者第一状态和第二状态均为形变部210的受力状态。
请继续参阅图2和图3，在一些可选的实施例中，贴合装置1还包括压合台600，压合台600包括用于容纳曲面盖板10的容置槽610，压合台600 位于柔性垫300背离形变承载件200的一侧，且压合台600沿高度方向可移动设置。
在这些可选的实施例中，在曲面盖板10和柔性屏20贴合过程中，可以将曲面盖板10设置于压合台600内，驱动压合台600沿靠近柔性垫300的方向移动，进而使得曲面盖板10向柔性垫300提供压合力，将曲面盖板10压合于柔性屏20上。
在一些可选的实施例中，贴合装置1还包括引导膜800，用于支撑柔性屏20。在贴合装置1的使用过程中，可以先将柔性屏20设置于引导膜800上，然后将引导膜800设置于柔性支撑件100上。引导膜800用于将柔性屏20带动至柔性支撑件100上。引导膜800的尺寸通常大于柔性屏20及支撑面310的尺寸。
可选的，如图3和图4所示，柔性垫300包括屋脊部300a，屋脊部300a位于形变部210的一侧，脊柱段311和倾斜段312均设置于屋脊部300a。可选的，柔性垫300还包括用于包裹异形承载部220的包裹部300b，包裹部300b连接于屋脊部300a两侧，支撑面310还包括设置于包裹部300b的异形段313，倾斜段312连接于异形段313和脊柱段311之间。在这些可选的实施例中，通过设置包裹部300b能够向柔性屏20提供更好的支撑，避免柔性屏20被形变承载件200划伤。
图3中为了更清晰的展示柔性垫300的结构，以点划线在柔性垫300上界定出了屋脊部300a和包裹部300b，点划线并不构成对本申请实施例贴合装置1结构上的限定。可选的，支撑面310的倾斜段312和脊柱段311用于支撑柔性屏20和曲面盖板10的平面部11相互贴合，支撑面310的异形段313用于支撑柔性屏20和曲面盖板10的弯曲部12相互贴合。
支撑件100的设置方式有多种，例如支撑件100固定连接于形变部210背离柔性垫300的一侧，且支撑件100在高度方向上不可变形设置。
在另一些可选的实施例中，形变部210通过支撑件100在高度方向上可变形设置。例如，支撑件100在高度方向上的延伸长度可调。当曲面盖板10的压合力不足以使得形变部210发生变形，或者为了进一步提高贴合效率，可以通过调节支撑件100在高度方向上的延伸长度，支撑件100向 形变部210提供朝向曲面盖板10的驱动力，驱动形变部210朝向曲面盖板10变形。
在另一些可选的实施例中，如图2至图4所示，贴合装置1还包括底座400，支撑件100支撑连接于底座400和形变部210之间，支撑件100与底座400在高度方向的相对位置可调。当曲面盖板10施加压合力时，可以驱动支撑件100朝向曲面盖板10移动，支撑件100带动形变部210朝向曲面盖板10变形。
例如，底座400包括沿高度方向延伸成型的第二滑槽420，支撑件100在第二滑槽420内沿高度方向可移动设置。第二滑槽420例如沿高度方向贯穿底座400设置，可以通过底座400背离形变承载件200的一侧驱动支撑件100在第二滑槽420内移动。
在又一些可选的实施例中，支撑件100还可以固定连接于底座400和形变部210之间。
形变承载件200的材料设置方式有多种，例如形变承载件200为弹性钢板，利用弹性钢板的结构弹性使得形变部210能够发生形变。形变承载件200的材料可以包括合金弹簧钢，例如形变承载件200的材料包括弹簧钢，例如弹簧钢为中国标准GB/T 1222-1984钢号60Si2MnA。
形变部210的设置方式有多种，例如形变部210由异形承载部220沿高度方向凹陷成型。形变部210包括容纳空间，使得至少部分柔性垫300能够容纳于容纳空间内，形变部210能够向柔性垫300提供更好的支撑。
此外，在这些可选的实施例中，当曲面盖板10向设置于支撑面310的柔性屏20施加压合力时，异形承载部220沿压合力的方向移动，形变部210在曲面盖板10和支撑件100的挤压作用下变形，形变部210通过配合面320作用于柔性垫300，使得支撑面310发生变形。
可选的，当形变部210由异形承载部220沿高度方向凹陷成型时，柔性垫300的配合面320和形变部210的形状相适配，柔性垫300的配合面320沿远离支撑面310的方向凸出设置，柔性垫300的厚度不一致。例如，在自然状态下，配合面320沿远离支撑面310的方向凸出设置，支撑面310沿远离配合面320的方向凸出呈屋脊状。当柔性垫300在形变部210的作 用下变形时，配合面320由自然状态下朝向支撑面310变形，支撑面310朝向配合面320变形，倾斜段312的倾斜度逐渐减小。
或者，在一些其他的实施例中，形变部210在自然状态下可以呈屋脊状，柔性垫300在形变部210的支撑作用下呈屋脊状。形变部210在曲面盖板10的压合作用下可以由第一状态变形至第二状态，柔性垫300跟随形变部210的变形而变形。
当形变部210由异形承载部220沿高度方向凹陷成型时，形变部210的横截面可以呈弧形或者V形。例如形变部210的横截面呈弧形，使得形变部210受力更易发生变形，不易发生褶皱。
形变部210的横截面例如是沿贴合装置1长度方向或者宽度方向的横截面。例如，异形承载部220沿宽度方向相对设置，形变部210连接于两个异形承载部220之间，形变部210的横截面为高度方向和宽度方向所在的平面。
可选的，支撑件100设置于两个异形承载部220的中间部位。例如当形变部210的横截面呈弧形时，支撑件100设置于形变部210背离柔性垫300的顶端，使得形变部210的受力更加平衡。
请一并参阅图6和图7，图6是本申请第一方面另一实施例提供的一种贴合装置1的立体结构示意图。图7是本申请第一方面另一实施例提供的一种贴合装置1的主视图。
在另一些实施例中，形变承载件200还包括两个侧部230，各侧部230分别支撑于各异形承载部220背离柔性垫300的一侧。侧部230用于向异形承载部220提供支撑。在贴合装置1的使用过程中，曲面盖板10压合柔性屏20时，侧部230向异形承载部220提供支撑，使得柔性屏20被挤压于异形承载部220和曲面盖板10之间，能够提高柔性屏20和曲面盖板10上弯曲部12之间的作用力大小，改善柔性屏20和弯曲部12之间的贴合气泡，进一步提升贴合良率。
为了提高形变承载件200的变形能力，在一些可选的实施例中，形变承载件200还包括两个过渡连接部240，各过渡连接部240过渡连接于异形承载部220和侧部230之间，两个过渡连接部240之间的距离在柔性垫300 至底座400的方向上逐渐减小。
在这些可选的实施例中，侧部230和异形承载部220之前连接有过渡连接部240，且两个过渡连接部240之间的距离在柔性垫300至底座400的方向上逐渐减小，即过渡连接部240呈弯曲状，能够提高形变承载件200的变形能力。
在贴合装置1的使用过程中，当曲面盖板10压合柔性屏20时，形变部210由第一状态转变至第二状态时，过渡连接部240发生变形，异形承载部220朝向侧部230移动，而形变部210在支撑件100的作用下不会向下移动，异形承载部220朝向侧部230移动能够进一步提高形变部210的变形程度，进一步降低倾斜段312的倾斜角度，提高曲面盖板10和柔性屏20之间的贴合良率。
在一些可选的实施例中，为了进一步提高形变承载件200的变形能力，异形承载部220通过侧部230在高度方向上的位置可调。例如，侧部230在高度方向上的延伸长度可调。当曲面盖板10压合柔性屏20，曲面盖板10向柔性屏20提供压合力时，侧部230在高度方向上收缩变形，进而带动异形承载部220朝向侧部230移动，带动形变部210发生更大程度的变形。
在另一些可选的实施例中，如图6和图7所示，贴合装置1还包括底座400，侧部230支撑连接于异形承载部220和底座400之间，侧部230与底座400在高度方向上相对位置可调设置。在这些可选的实施例中，当曲面盖板10压合柔性屏20，曲面盖板10向柔性屏20提供压合力时，侧部230朝向底座400移动，进而带动异形承载部220朝向侧部230移动。
请参阅图8，图8是图7中I处的局部放大结构示意图。
在一些可选的实施例中，如图8所示，底座400上设置有沿高度方向延伸的第一滑槽410，侧部230背离异形承载部220的一端位于第一滑槽410，且侧部230相对第一滑槽410沿高度方向可移动设置。在这些可选的实施例中，侧部230在第一滑槽410内可移动设置，使得侧部230相对底座400在高度方向上可滑动设置，当曲面盖板10向柔性屏20提供压合力时，侧部230可以沿第一滑槽410移动。
第一滑槽410的设置方式有多种，例如第一滑槽410在高度方向上贯 穿底座400设置，能提高侧部230在高度方向上的总移动距离。
侧部230和第一滑槽410相互配合的方式有多种，例如侧部230和第一滑槽410过盈配合。当形变承载件200处于自然状态时，侧部230依靠其与第一滑槽410内壁面之间的摩擦力被支撑于第二滑槽420内。当曲面盖板10施加压合力，侧部230受到的压力大于其与第一滑槽410内壁面之间的摩擦力时，侧部230沿高度方向移动，带动异形承载部220朝向侧部230移动。
或者，在另一些可选的实施例中，请继续参阅图8，侧部230背离异形承载部220的一端连接有复位件500，复位件500在高度方向上可往复变形设置。通过复位件500的往复变形，使得侧部230能够沿高度方向移动。复位件500例如为弹簧。
在这些可选的实施例中，当曲面盖板10没有提供压合力时，复位件500处于自然伸长状态，侧部230、异形承载部220和形变部210均处于自然状态。当曲面盖板10提供压合力时，复位件500收缩，异形承载部220在曲面盖板10的压合作用下朝向侧部230移动，形变部210在支撑件100的作用下发生变形。此外，通过在侧部230上设置复位件500，当曲面盖板10和柔性屏20贴合完毕并由贴合装置1上取下时，侧部230在复位件500的回弹力作用下会回复到原状，贴合装置1可以继续用于贴合下一组的柔性屏20和曲面盖板10。
可选的，侧部230上既连接有复位件500，底座400上也设置有第一滑槽410，复位件500设置于第一滑槽410，侧部230通过复位件500在第一滑槽410内沿高度方向可移动设置。
请参阅图9，图9是本申请第一方面再一实施例提供的一种贴合装置1的结构示意图。
在一些可选的实施例中，贴合装置1还包括加热部件700，设置于形变承载件200背离柔性垫300的一侧。通过加热部件700能够向形变承载件200、柔性垫300及位于柔性垫300上的柔性屏20提供热能，使得柔性垫300具有更好的变形能力，柔性屏20具有较好的柔性，进而改善曲面盖板10和柔性屏20之间的贴合气泡。
加热部件700的设置位置有多种，例如加热部件700设置于形变部210背离柔性垫300的一侧。
在另一些可选的实施例中，异形承载部220由形变部210沿背离柔性垫300的方向弯折形成，以在异形承载部220背离柔性垫300的一侧形成让位空间221，加热部件700设置于让位空间221内。
在这些可选的实施例中，加热部件700设置于异形承载部220形成的让位空间221内，加热部件700能够更好的加热异形承载部220，异形承载部220温度升高令柔性垫300的异形段313具有更好的变形能力，令柔性屏20的异形部与曲面盖板10更好的贴合。
请一并参阅图10至图13，图10是本申请第一方面另一实施例提供的一种贴合装置1在第一状态下的立体结构示意图；图11是本申请第一方面另一实施例提供的一种贴合装置1在第一状态下的主视图；图12是本申请第一方面另一实施例提供的一种贴合装置1在第二状态下的立体结构示意图；图13是本申请第一方面另一实施例提供的一种贴合装置1在第二状态下的主视图。
根据本申请实施例的贴合装置1，如图10和图11所示，在压合的起始阶段，形变部210处于第一状态下，曲面盖板10首先和柔性垫300上脊柱段311支撑的柔性屏20相互贴合。如图12和图13所示，向曲面盖板10施加压力，或者调整支撑件100在高度方向上的位置，形变部210由第一状态变形至第二状态的过程中，曲面盖板10和柔性屏20的接触为从中间向两边逐渐压合。最后，曲面盖板10和柔性屏20完全贴合。
本申请实施例能够有效改善曲面盖板10和柔性屏20之间的贴合气泡，提高产品良率。且在第一状态下，形变承载件200在宽度方向上的尺寸较小，当曲面盖板10的弯曲部12弯折角度较大时，位于形变承载件200和柔性垫300上的柔性屏20依然能够与曲面盖板10从中间向两边逐渐压合。
在一些可选的实施例中，形变承载件200的形变部210及异形承载部220的形状和曲面盖板10相适配。当曲面盖板10上设置有挖孔时，形变部210的对应位置设置有贯穿孔，避免柔性垫300在曲面盖板10和形变部210的挤压下剐蹭到挖孔的孔壁。
形变承载件200的厚度的设置方式有多种，在一些可选的实施例中，形变承载件200的厚度为0.5mm～3mm。当形变承载件200的厚度在0.5mm～3mm之间时，既能够避免形变承载件200的厚度不足导致形变承载件200无法承载柔性屏20和曲面盖板10，还能够避免形变承载件200太厚导致其难以发生变形。进一步的，形变承载件200的厚度为1mm～2mm。
柔性垫300的材料设置方式有多种，例如柔性垫300的材料包括硅胶，或者柔性垫300的材料包括聚酰亚胺薄膜、聚酯薄膜、氟化镁薄膜、硫化锌薄膜、有机无机层叠薄膜中的一种或几种。使用这些材料能够保证柔性垫300具有良好的柔性。
请一并参阅图14，图14是本申请第二方面实施例提供的一种贴合方法的流程示意图。
根据本申请第二方面实施例提供的贴合方法，贴合方法，用于贴合曲面盖板10和柔性屏20。该方法可以使用上述任一实施例的贴合装置1完成，贴合方法包括：
步骤S1：将柔性屏20放置于柔性垫300上，并使得形变部210处于第一状态下。
如上所述，当形变部210处于第一状态下时，柔性垫300的支撑面310呈屋脊状，当贴合装置1包括底座400时，脊柱段311至底座400的距离大于异形段313至底座400的距离。
当贴合装置1包括引导膜800时，首先将引导膜800设置于柔性垫300上，接着将柔性屏20放置于引导膜800上。然后将带有柔性屏20的引导膜800设置于柔性垫300上。尚未开始压合曲面盖板10时，形变部210处于第一状态下。
当形变承载件200在自然状态下呈如图4所示的状态时，使用时直接将柔性屏20设置于柔性垫300上。当形变承载件200在自然状态下呈如图5所示的状态时，在将柔性屏20设置于形变承载件200上前，或者在将柔性屏20设置于形变承载件200上后，驱使形变部210处于第一状态。
步骤S2：将曲面盖板10盖设于柔性屏20上。
当贴合装置1包括压合台600时，可以将曲面盖板10设置于压合台 600的容纳槽内，进而使得压合台600能够带动曲面盖板10移动，并将曲面盖板10盖设于柔性屏20上。由于当形变部210处于第一状态下时柔性垫300的支撑面310呈屋脊状，因此曲面盖板10首先与脊柱段311支撑的部分柔性屏20相互贴合。
步骤S3：向曲面盖板10施加压力，使得曲面盖板10和柔性屏20相互贴合。
向曲面盖板10施加压力，使得形变部210由第一状态变形至第二状态，两个异形承载部220沿相互远离的方向移动，曲面盖板10和柔性屏20由所述脊柱段311对应的位置逐渐贴合。
在这些可选的实施例中，当曲面盖板10设置于压合台600时，通过压合台600向曲面盖板10施加压力，进而使得形变部210由第一状态变形至第二状态，曲面盖板10和柔性屏20逐渐贴合。由于柔性屏20与曲面盖板10的接触为从中间向两边逐渐压合，因此可有效排除曲面盖板10和柔性屏20之间的贴合气泡，提高产品的良率。
本领域技术人员应能理解，上述实施例均是示例性而非限制性的。在不同实施例中出现的不同技术特征可以进行组合，以取得有益效果。本领域技术人员在研究附图、说明书及权利要求书的基础上，应能理解并实现所揭示的实施例的其他变化的实施例。某些技术特征出现在不同的从属权利要求中并不意味着不能将这些技术特征进行组合以取得有益效果。
