Description

一种真空贴膜盒 技术领域
本发明涉及贴膜器技术领域，具体涉及一种真空贴膜盒。
背景技术
随着智能技术的迅猛发展，诸如手机、平板电脑等电子设备广泛应用于我们的生活中。为了对电子设备的显示屏起保护作用，通常用户在电子设备的显示屏上贴上保护膜，以对显示屏起保护作用。然而，在贴保护膜的过程中，通常是人手直接将保护膜贴在显示屏上，或者采用一些辅助贴膜器来贴膜，但贴后的保护膜与显示屏之间往往留有少量空气，导致气泡产生，影响贴膜质量。
发明内容
本发明的目的在于针对现有技术的缺陷和不足，提供一种真空贴膜盒，具有贴膜不易产生气泡的优势。
为实现上述目的，本发明采用的技术方案是：一种真空贴膜盒，包括：底盒、盖板和弹性软膜；所述底盒开设有抽气孔；所述盖板开设有通气孔；所述盖板盖设于所述底盒上侧；所述弹性软膜位于所述底盒和所述盖板之间，所述弹性软膜贴着所述盖板的内侧，所述弹性软膜与所述底盒之间形成第一空间；所述第一空间用于供电子设备和保护膜放置；所述抽气孔连通所述第一空间及所述底盒外部，用于与外部负压设备连接。
本发明进一步设置，所述盖板的内侧面为平面。
本发明进一步设置，所述底盒开设有排气孔。
本发明进一步设置，所述底盒与所述盖板为可拆卸连接，当所述底盒与所述盖板连接时，所述底盒与所述盖板夹持固定所述弹性膜。
本发明进一步设置，所述底盒的上侧设置有凸圈，所述盖板的下侧设置有对应于所述凸圈的凹槽。
本发明进一步设置，所述底盒内设置有用于将电子设备居中定位的第一限位装置。
本发明进一步设置，所述底盒内设置有用于将保护膜居中定位的第二限位装置。
本发明进一步设置，所述真空贴膜盒还包括：装配于所述底盒上且与所述抽气孔连通的负压设备。
本发明进一步设置，所述盖板的顶部呈弧形凸起状，且设置有多条第一加强筋；所述底盒的底部呈弧形凸起状，且设置有多条第二加强筋。
本发明进一步设置，所述真空贴膜盒包括：一端可拆卸连接所述排气孔且用于密封所述排气孔，另一端可拆卸连接所述通气孔且用于密封所述通气孔的密封插条。
采用上述技术方案后，本发明有益效果为：在本发明中，通过在底盒和盖板之间设置有弹性软膜，底盒与弹性软膜之间形成第一空间，盖板与弹性软膜贴合，且在底盒开设有抽气孔，在盖板开设有通气孔，使用时将电子设备和保护膜置入第一空间内，密封通气孔，启动负压设备，由于盖板与弹性软膜之间不存在空间或仅有微小的空间，在负压设备抽真空时，弹性软膜并不会下压，当第一空间内没有空气时，不再密封通气孔，外界气体能够通过通气孔进入到弹性软膜的上侧，此时负压设备继续抽真空，弹性软膜会向下压，将保护膜压紧在电子设备的屏幕上，完成贴膜。由于第一空间内没有空 气，从而贴膜后不会产生气泡。
为实现上述目的，本发明采用的另一种技术方案是：一种真空贴膜盒，包括：底盒、盖板和弹性软膜；所述底盒开设有抽气孔；所述盖板开设有通气孔；所述盖板盖设于所述底盒上侧；所述弹性软膜位于所述底盒和所述盖板之间，且与所述底盒之间形成第一空间，与所述盖板之间形成第二空间；所述第一空间用于供电子设备和保护膜放置；所述抽气孔连通所述第一空间及所述底盒外部，用于与负压设备连接；所述通气孔连通所述第二空间及所述上盖外部，用于与外部负压设备连接。
本发明进一步设置，所述底盒开设有排气孔。
本发明进一步设置，所述底盒与所述盖板为可拆卸连接，当所述底盒与所述盖板连接时，所述底盒与所述盖板夹持固定所述弹性膜。
本发明进一步设置，所述底盒的上侧设置有凸圈，所述盖板的下侧设置有对应于所述凸圈的凹槽。

本发明进一步设置，所述盖板的顶部呈弧形凸起状，且设置有多条第一加强筋；所述底盒的底部呈弧形凸起状，且设置有多条第二加强筋。
采用上述技术方案后，本发明有益效果为：在本发明中，通过在底盒和 盖板之间设置有弹性软膜，底盒与弹性软膜之间形成第一空间，盖板与弹性软膜之间形成第二空间，且在底盒开设有抽气孔，在盖板开设有通气孔，使用时将电子设备和保护膜置入第一空间内，启动负压设备，第一空间和第二空间同时抽气，保持两个空间气压平衡，直到第一空间内没有空气，接着第一空间继续抽气，第二空间停止抽气，且有外部气体进入，从而弹性软膜会向下压，将保护膜压紧在电子设备的屏幕上，完成贴膜。由于第一空间内没有空气，从而贴膜后不会产生气泡。

具体实施方式
以下结合附图对本发明作进一步详细说明。
本具体实施例仅仅是对本发明的解释，其并不是对本发明的限制，本领域技术人员在阅读完本说明书后可以根据需要对本实施例做出没有创造贡献的修改，但只要在本发明的权利要求范围内都受到专利法的保护。
实施例一：本实施例涉及一种真空贴膜盒，如图1-图2所示，包括：底盒1、盖板2、负压设备4和弹性软膜3。在贴膜时，还需用到电子设备和保护膜。
底盒1开设有抽气孔c，盖板2开设有通气孔e。盖板2盖设于底盒1上侧。弹性软膜3位于底盒1和所述盖板2之间，且与底盒1之间形成第一空间a。盖板2的内侧面为平面，弹性软膜3贴着所述盖板2的内侧，盖板2与弹性软膜3之间不存在空间或仅有微小的空间。第一空间a用于供电子设备和保护膜放置。在本实施例中，抽气孔c连通第一空间a及负压设备4。在其他实施例中，真空贴膜盒可以不设置有负压设备4，而是采用外部负压设备来 抽真空，即抽气孔c连通第一空间a及底盒1外部，用于与外部负压设备连接。在本实施例中，通气孔e设置于盖板2的上侧。
使用时将电子设备和保护膜置入第一空间a内，密封通气孔e，启动负压设备4，由于盖板2与弹性软膜3之间不存在空间或仅有微小的空间，在负压设备4抽真空时，弹性软膜3并不会下压，当第一空间a内没有空气时，不再密封通气孔e，外界气体能够通过通气孔e进入到弹性软膜3的上侧，此时负压设备4继续抽真空，弹性软膜3会向下压，将保护膜压紧在电子设备的屏幕上，完成贴膜。由于第一空间a内没有空气，从而贴膜后不会产生气泡。
在本实施例中，如图3所示，负压设备4包括：壳体41，设于壳体41内的微型气泵42以及设置于壳体41上、用于供微信气泵充电的充电口43。
作为一个优选的方案，如图1-图3所示，底盒1开设有排气孔d，排气孔d与第一空间a连通。在贴膜时需要密封排气孔d，而在贴膜后，将排气孔d导通，能起到泄压作用，便于将盖板2打开。
底盒1与盖板2为可拆卸连接，当底盒1与盖板2连接时，底盒1与盖板2夹持固定弹性膜。具体在本实施例中，如图1和图2所示，底盒1的上侧设置有凸圈11，盖板2的下侧设置有对应于凸圈11的凹槽21。凸圈11与凹槽21的配合，提高了底盒1与盖板2之间的密封性。在其它实施例中，底盒1与盖板2还可以通过其它方式可拆卸连接，例如卡扣连接等。
在本实施例中，弹性软膜3为弹性薄膜。在其他实施例中，弹性软膜3也可以为弹性袋。弹性袋可以直接套住整个盖板2。
作为一个优选的方案，如图1和图2所示，底盒1内设置有用于将电子设备居中定位的第一限位装置，还设置有用于将保护膜居中定位的第二限位装置。通过设置第一限位装置和第二限位装置，既能够提高电子设备贴膜的 准确度，又能够便于悬挂保护膜。具体在本实施例中，第一限位装置为多个设置于底盒1内边角的导向块(未图示)，电子设备放置于多个导向块之间，居中定位在底盒1内。第二限位装置为两个分别设置于底盒1内部两侧的限位凸柱12，保护膜通过其两侧的两个定位孔悬挂在限位凸柱12上，使保护膜居中定位在电子设备上方。
保护膜至少有三层，依次为离型膜、保护膜本体以及定位膜。贴膜时，需要先将离型膜撕掉，再将定位膜固定在底盒1内，使保护膜本体朝向电子设备上方，贴膜时，定位膜自动撕开，或贴膜后人为将定位膜撕开。
负压设备4工作时，盖板2和底盒1容易产生形变，为了防止这种情况产生，如图所示，盖板2的顶部呈弧形凸起状，且设置有多条第一加强筋22，底盒1的底部呈弧形凸起状，且设置有多条第二加强筋13。具体在本实施例中，盖板2的顶部设置有多条竖向设置的第一加强筋22，多条横向设置的第一加强筋22，横竖设置的第一加强筋22彼此交错，进一步提高了盖板2的稳固性。底盒1的底部设置有多条竖向设置的第二加强筋13，多条横向设置的第二加强筋13，横竖设置的第二加强筋13彼此交错，进一步提高了盖板2的稳固性。
真空贴膜盒还设置有：一端可拆卸连接排气孔d且用于密封排气孔d，另一端可拆卸连接通气孔e且用于密封通气孔e的密封插条(未图示)。在需要密封排气孔d和通气孔e时，将密封插条的两端均插上，在仅需密封其中一个孔时，则将密封插条相应的一端插上即可。
该真空贴膜盒还可以配合UV固化设备使用，只需将盖板2设置成透明状。使用时，先用真空贴膜盒进行贴膜，随后启动位于真空贴膜盒上侧的UV固化设备，对真空贴膜盒内的保护膜进行固化。
实施例二：本实施例涉及一种真空贴膜盒，与实施例一不同的是，如图4和图5所示，在本实施例中，不设置有负压设备4，而是采用外部负压设备来抽真空。且弹性软膜3与盖板2之间形成第二空间b；通气孔e连通第二空间b及上盖2外部，用于与外部负压设备连接。
通气孔e设置于盖板2的侧壁上，与底盒1的抽气孔c位于同一侧。通气孔e与抽气孔c位于同一侧，便于外部负压设备的连接。
使用时将电子设备和保护膜置入第一空间a内，启动外部负压设备，第一空间a和第二空间b同时抽气，保持两个空间气压平衡，直到第一空间a内没有空气，接着第一空间a继续抽气，第二空间b停止抽气，且有外部气体进入，从而弹性软膜3会向下压，将保护膜压紧在电子设备的屏幕上，完成贴膜。由于第一空间a内没有空气，从而贴膜后不会产生气泡。
除此之外，如图5所示，盖板2的内侧设置有紫外灯5。贴膜后，开启紫外灯5，能够将保护膜固化。
实施例三：本实施例涉及一种真空贴膜盒，与实施例二不同的是，如图6和图7所示，在本实施例中，直接设置有负压设备4。作为一个优选的方案，负压设备4与底盒1和盖板2之间为可拆卸连接。
通气孔e与抽气孔c位于同一侧。负压设备4与通气孔e和抽气孔c连通。抽气孔c和通气孔e的孔径比例与第一空间a和第二空间b的容积比例相同，以保证初始阶段抽气时，保护膜不会下压。在本实施例中，负压设备4的壳体41内还设有电源组件，能够为紫外灯5和负压设备4供电。
在本实施例中，底盒1内同样设置有用于将电子设备居中定位的第一限位装置，以及有用于将保护膜居中定位的第二限位装置。
如图8-图10所示，第一限位装置包括：可拆卸装配于底盒1内侧壁的第 一限位件14，可拆卸装配于底盒1内侧壁、且与第一限位件14相对设置的第二限位件15，可拆卸装配于底盒1内侧壁、且与第一限位件14垂直设置的第三限位件16，以及可拆卸装配于底盒1内侧壁、且与第三限位件16相对设置的第四限位件17。第一限位件14、第二限位件15、第三限位件16和第四限位件17共同围成一个供电子设备定位放置的矩形空间。
通过在底盒1的四个内侧壁分别可拆卸装配有第一限位件14、第二限位件15、第三限位件16和第四限位件17，这四个限位件共同围成一个供电子设备定位放置的矩形空间，只需通过更换不同规格的限位件，即可适用不同尺寸的电子设备，适用性广。
在本实施例中，如图9所示，底盒1的内侧壁上设置有分别供第一限位件14、第二限位件15、第三限位件16和第四限位件17可拆卸插接的插槽18。且第一限位件14、第二限位件15、第三限位件16和第四限位件17均呈片状。
作为一个优选的方案，如图10所示，第一限位件14、第二限位件15、第三限位件16和第四限位件17的底部均设有向前延伸的、供电子设备的底部放置的垫高块141。且垫高块141的高度大于电子设备后置摄像头凸起的厚度。通过设有垫高块141，使得电子设备的后置摄像头不会接触到底盒1的底部，既不会磨花后置摄像头，也不会因后置摄像头而影响贴膜时的平衡。
如图10所示，第二限位装置为：两个分别设置于第一限位件14和第三限位件16的顶部的有定位凸柱142。定位凸柱142用于与保护膜上的定位孔配合，完成对保护膜的定位。
在本实施例中，底盒1呈矩形状。在其他实施例中，底盒1还可以呈椭圆形状。在本实施例中，第一限位件14和第三限位件16各有一个，第二限位件15和第四限位件17各有两个。由于电子设备，如手机的左右两侧较长， 所以第二限位件15和第四限位件17各有两个，能够更好的定位。
以上，仅用以说明本发明的技术方案而非限制，本领域普通技术人员对本发明的技术方案所做的其它修改或者等同替换，只要不脱离本发明技术方案的精神和范围，均应涵盖在本发明的权利要求范围当中。
