在本公开实施例中，所述第二密封圈的结构示意图如图5所示。结合图1-5，所述第二密封圈104包括第二上密封圈1041和第二下密封圈1042。第二上密封圈1041设置于第一模板101上，第二下密封圈1042设置于第二模板102上；并且在第一模板101和第二模板102匹配后，第二上密封圈1041和第二下密封圈1042都位于工件区105和固定区106之间，且位置相对，可以对匹配后的第一模板101和第二模板102进行更充分的密封。
在一些实施例中，所述第一密封圈和第二密封圈嵌合在所述第一模板和所述第二模板中。
本公开实施例提供的镀膜夹具还包括多个固定壳，所述固定壳上还设有多个第一定位柱，用来防止所述待镀件的待镀膜部分的位置发生偏离。如图6所示。图6示出了根据本公开的一个实施例的固定壳的结构示意图。所述固定壳601上设置有四个第一定位柱602，用于限定所述待镀件的待镀膜部分的位置。结合图3和图6，所述第二模板102在每个工位的镀膜区109都设置有安装位，用于放置固定壳601。在实际操作中，由于第一定位柱的限定作用，工作人员只需将所述待镀件的待镀膜部分放置于四个第一定位柱之间即可，并且在镀膜过程中，第一定位柱还可以保证所述待镀件的待镀膜部分不会发生大的移动从而导致所述待镀膜部分未被完全镀膜。
在一些其他的实施例中，所述第一定位柱也可以设置为其他形状，位于同一个固定壳上的不同第一定位柱的形状可以相同也可以不同；并且所述第一定位柱的个数也不限制为四个。例如，所述第一定位柱可以设置为长方体，数量可以设置为三个。
在一些实施例中，所述固定壳通过背胶设置于所述第二模板的安装位上。在一些其他的实施例中，所述固定壳也可以通过其他方式设置于所述第二模板的安装位上。例如：也可以将所述固定壳嵌合于所述第二模板的安装位上。
本公开实施例提供的镀膜夹具还包括多个限位块，所述限位块上设有多个第二定位柱，用来防止所述待镀件的非镀膜部分的位置发生偏离。如图7所示。图7示出了根据本 公开的一个实施例的限位块的结构示意图。所述限位块701上设置有两个第二定位柱702，用于固定所述待镀件的非镀膜部分。结合图3和图7，限位块701放置在第二模板102上，且对应于遮蔽区110的位置，用于对所述待镀件的非镀膜部分提供机械支撑，并通过所述限位块701上的第二定位柱702对待镀件的非镀膜部分进行位置的限定。在实际操作中，由于第二定位柱的限定作用，工作人员只需将所述待镀件的非镀膜部分放置于两个第二定位柱之间即可，并且在镀膜过程中，第二定位柱还可以保证所述待镀件的非镀膜部分不会发生大的移动从而导致所述非镀膜部分被意外镀膜。
在一些其他的实施例中，所述第二定位柱也可以设置为其他形状，位于同一个限位块上的不同第二定位柱的形状可以相同也可以不同；并且所述第二定位柱的个数也不限制为两个。例如，所述第二定位柱可以设置为圆柱体，数量可以为四个。
在一些实施例中，所述限位块通过背胶设置于所述第二模板上。在一些其他的实施例中，所述限位块也可以通过其他方式设置于所述第二模板上。例如：也可以将所述固定壳嵌合于所述第二模板上的遮蔽区中。
设置在固定壳上的第一定位柱和设置在限位块上的第二定位柱使得操作人员将待镀件放置于镀膜夹具上时无需进行精准地放置即可将待镀件的待镀膜部分限定在镀膜夹具的镀膜区进行镀膜，可以简化操作，便于镀膜；并且使得在进行镀膜时，待镀件的非镀膜部分可以被限定在镀膜夹具的遮蔽区，避免待镀件的位置偏离。

不同规格的镀膜夹具包括的单元数量、每个单元中工位组的数量、每个工位组中工位的数量都存在差异，只在固定区对所述镀膜夹具进行固定，无法保证位于所述镀膜夹具中不同位置的待镀件受到所述镀膜夹具的压合力均匀，从而容易导致受到较小压合力的待镀件的非镀膜部分也被镀膜。所述加强固定区位于不同单元以及不同工位组之间，通过在所述加强固定区设置所述加强螺钉，可以使处于所述镀膜夹具各处的待镀件受到均匀的压合力，保证镀膜夹具对待镀件的非镀膜部分的遮蔽效果。
具体的，如图1所示，在第一模板101和第二模板102匹配后，加强螺钉1121被设置在工件区105的加强固定区112，即图1工件区105中虚线所示的位置，可以使位于镀膜夹具10内部的不同位置的待镀件都受到均匀的压合力，从而提高成品率。结合图2所示的第一模板的结构示意图和图3所示的第二模板的结构示意图可以看出，在本公开实施例 中，在第一模板101和第二模板102匹配后，使用加强螺钉1121对第一模板101和第二模板102进行压合，加强螺钉1121被设置于镀膜区109和遮蔽区110之间，且位于在每组工位108之间，可以保证力的压合均匀，使得放置在镀膜夹具10内不同位置的待镀件的待镀膜部分和非镀膜部分都可以被隔开，达到更好的遮蔽效果。

具体的，如图6所示，固定壳601上设置有四个第一定位柱602，用于限定所述待镀件的待镀膜部分的位置。结合图3和图6，第二模板102在每个工位108的镀膜区109都设有安装位，用于放置固定壳601。在使用所述镀膜夹具进行镀膜遮蔽时，由于第一定位柱的限定作用，工作人员只需将所述待镀件的待镀膜部分放置在四个定位柱之间即可，并且在镀膜过程中，所述第一定位柱还可以保证所属待镀件的待镀膜部分不会发生大的移动从而导致所述待镀膜部分未被完全镀膜。
在一些实施例中，所述第一定位柱也可以设置为其他的形状，位于同一个固定壳上的不同第一定位柱的形状可以相同也可以不同；并且所述第一定位柱的个数也不限制为四个。例如，所述第一定位柱可以设置为长方体，数量可以设置为三个。
在一些实施例中，所述固定壳通过背胶设置于所述第二模板的安装位上。在一些其他的实施例中，所述固定壳也可以通过其他方式设置于所述第二模板的安装位上。例如：也可以将所述固定壳嵌合于所述第二模板的安装位上。
在一些实施例中，在所述第二模板上还设置有限位块，通过所述限定块可以限定所述待镀件的非镀膜部分的位置，所述限位块上设有多个第二定位柱，用于防止所述待镀件的非镀膜部分的位置偏离。
具体的，如图7所示，限位块701上设置有两个第二定位柱702，用于固定所述待镀件的非镀膜部分。结合图3和图7，限位块701放置在第二模板102上，且对应于遮蔽区110的位置，用于对所述待镀件的非镀膜部分提供机械支撑，并通过所述限位块701上的第二定位柱702对待镀件的非镀膜部分进行位置的限定。在放置待镀件时，由于第二定位 柱的限定作用，工作人员只需将所述待镀件的非镀膜部分放置在同一个限定块的两个第二定位柱之间即可，并且在镀膜过程中，所述第二定位柱还可以保证所述待镀件的非镀膜部分不会发生大的移动从而导致所述非镀膜部分被意外镀膜。
在一些其他的实施例中，所述第二定位柱也可以设置为其他的形状，位于同一个限位块上的不同第二定位柱的形状可以相同也可以不同；并且所述第二定位柱的个数也不限制为两个。例如，所述第二定位柱可以设置为圆柱体，数量可以为四个。
在一些实施例中，所述限位块也可以通过背胶设置于所述第二模板上。在一些其他的实施例中，所述限位块也可以通过其他方式设置于所述第二模板上。例如，也可以通过将所述限位块嵌合于所述第二模板上的遮蔽区。
设置在固定壳上的第一定位柱和设置在限位块上的第二定位柱使得操作人员将待镀件放置于镀膜夹具上时无需进行精准地放置即可将待镀件的待镀膜部分限定在镀膜夹具的镀膜区进行镀膜，可以简化操作，便于镀膜；并且使得在进行镀膜时，待镀件的非镀膜部分可以被限定在镀膜夹具的遮蔽区得到充分遮蔽，同时避免待镀件的位置偏离。
在将所述待镀件放置在所述第二模板后，将所述第一模板与所述放有所述待镀件的第二模板进行匹配，围成所述镀膜夹具。
在一些实施例中，在所述镀膜夹具的固定区，通过固定螺钉对所述第一模板和所述第二模板进行紧固。在一些其他的实施例中，也可以通过其他紧固件对所述第一模板和所述第二模板进行紧固。
在一些实施例中，在所述镀膜夹具上还设置有加强固定区，位于所述工件区内，所述加强固定区用来设置加强螺钉，从而对匹配后的第一模板和第二模板进行紧固。
不同规格的镀膜夹具包括的单元数量、每个单元中工件组的数量、每个工位组中工位的数量都可以不同，只在所述固定区对所述镀膜夹具进行固定无法保证所述镀膜夹具施加给所述镀膜夹具中不同位置的待镀件的压合力均匀。一些待镀件受到来自所述镀膜夹具的压合力较小，第一密封圈无法起到阻隔所述待镀件待镀膜部分和非镀膜部分的作用，容易导致所述待镀件的非镀膜部分不能被很好地遮蔽。所述加强固定区可以位于不同单元以及不同的工位组之间，通过在所述加强固定区设置所述加强螺可以钉，使处于所述镀膜夹具中各处的待镀件受到均匀额定压合力，保证所述镀膜夹具对所述待镀件的非镀膜部分的遮蔽效果。
继续参照图1，在第一模板101和第二模板102围成镀膜夹具10后，在固定区106通 过固定螺钉1061将第一模板101和第二模板102进行紧固，并在工件区105的加强固定区112设置加强螺钉1121，从而使位于镀膜夹具10内部不同位置的待镀件都受到均匀的压合力，从而提高成品率。结合图2所示的第一模板的结构示意图和图3所示的第二模板的结构示意图，在第一模板101和第二模板102上对应加强固定区112的位置都分别设有加强螺孔1122，在本公开实施例中，在第一模板101和第二模板102围成镀膜夹具10后，加强螺钉1121被设置在镀膜区109和遮蔽区110之间的加强螺孔1122处，且位于相邻的两个工位组之间，可以保证力的压合均匀，使得放置在镀膜夹具10内不同位置的待镀件的待镀膜部分和非镀膜部分都可以被隔开，实现对待镀件的非镀膜部分的遮蔽。
通过在第一模板和第二模板上都形成第一密封圈和第二密封圈，在进行镀膜遮蔽时，第一密封圈可以隔开待镀件的待镀膜部分和非镀膜部分，第二密封圈可以对围成的镀膜夹具进行密封。能够通过较少的密封材料对待镀件的待镀膜部分和非镀膜部分进行阻隔，保证待镀件的待镀膜部分被镀膜的同时防止所述待镀件的非镀膜部分被意外镀膜。
以上已揭示本公开的技术内容及技术特点，然而可以理解，在本公开的创作思想下，本领域的技术人员可以对上述公开的构思作各种变化和改进，但都属于本公开的保护范围。上述实施方式的描述是例示性的而不是限制性的，本公开的保护范围由权利要求所确定。
