 本发明的实施方式
下面结合附图对本发明的具体实施方式作进一步说明。在此需要说明的是，对于这些实施方式的说明用于帮助理解本发明，但并不构成对本发明的限定。此外，下面所描述的本发明各个实施方式中所涉及的技术特征只要彼此之间未构成冲突就可以相互组合。
实施例一
如图1及图2所示，本发明实施例一提供一种定位夹具100，该定位夹具100包括夹具上模110与夹具下模120，夹具上模110与夹具下模120相互扣合连接。夹具下模120邻近夹具上模110的一侧表面设置有槽体121，以对应容置LED显示模组的LED灯板200。夹具上模110邻近夹具下模120的一侧表面上固设有紫外线灯板130。
在本实施例中，如图2所示，紫外线灯板130通过四颗固定螺钉固定在夹具上模110邻近夹具下模120的一侧表面上。槽体121为矩形槽体，以更好地适配市面上大部分的LED灯板200。槽体121的底壁上凸设有若干三角凸起122，以在LED灯板200容置于槽体121时对应卡设在相应的灯缝中；槽体121的底壁设置有若干抽真空气孔123，且若干抽真空气孔123外接真空泵（未图示）。通过真空泵经若干抽真空气孔123对槽体121进行抽真空处理，使得每一LED灯板200与槽体121的底壁之间产生负压，以通过大气压将每一LED灯板200的灯缝均匀地压在相应三角凸起122上。此时，所有的三角凸起的尖部在第一平面上，灯珠与三角凸起122的斜面接触，保证灯面都在第二平面上，进而保证LED灯板200在此时具有很高的平整度。三角凸起122具体包括若干纵向设置的第一三角凸起1221及若干横向设置的第二三角凸起1222，第一三角凸起1221可对应卡设在纵向延伸的灯缝上，第二三角凸起1222可对应卡设在横向延伸的灯缝上，横纵设置的三角凸起122可确保LED灯板很好地定位在槽体121中，不会发生水平方向上的左右前后移位。具体地，如图2所示，两两相邻的第一三角凸起1221之间的间距为LED灯板200的两两横向相邻的灯缝之间的间距的N倍，N为大于或等于1的正整数。两两相邻的第二三角凸起1222之间的间距为LED灯板的两两纵向相邻的灯缝之间的间距的M倍，M为大于或等于1的正整数。即卡设LED灯板200的第一三角凸起1221的数量可等于或少于该LED灯板200中纵向延伸的灯缝的数量，卡设LED灯板200的第二三角凸起1222的数量可等于或少于该LED灯板200中横向延伸的灯缝的数量。
如图2所示，夹具下模120的一侧设置有真空泵接入口124，以接入真空泵。夹具下模125内置若干气道（未图示），若干气道的一侧连通若干抽真空气孔123，若干气道的另一侧连通真空泵接入口124。具体地，槽体121的内侧环设有硅胶垫圈125，且硅胶垫圈125与槽体121的每一侧壁贴合连接。通过硅胶垫圈125的设置，可实现LED灯板200与槽体121之间的过盈配合，在对LED灯板200进行进一步定位固定的同时，确保LED灯板200的灯面与槽体121之间形成密封空间。定位上模110与定位下模120之间通过若干定位凸起11与若干定位凹槽12一一对应配合来进行相互扣合连接。每一定位凸起11优选设有5度拔模角，与定位凹槽12适配，具有很好的定位作用。本实施例中具体在定位上模110的四个边角设置四个定位凹槽12，在定位下模120的四个边角设置四个定位凸起11，以实现定位上模110与定位下模120之间的进行相互扣合连接，对于本领域技术而言，可根据实际需要对一一配合的定位凸起11与定位凹槽12的数量进行适当增减，或改变其设置位置（如在定位上模110的四个边角设置四个定位凸起11，在定位下模120的四个边角设置四个定位凹槽12）。
如图2所示，夹具上模110邻近夹具下模120的一侧设置有若干底壳夹头140，夹具上模110远离夹具下模120的一侧设置有开关板151，开关板151的内侧设置有若干开关针152，若干开关针152与若干底壳夹头140一一对应设置，以控制相应的底壳夹头140开合。具体地，每一底壳夹头140包括两片夹子，含有一定的弹性，当开关针152向夹具下模120所在的运动时涨开夹子，松开底壳。夹具上模110远离夹具下模120的一侧设置有开关板安装槽111，开关板151安设于开关板安装槽111中，且开关板151与开关板安装槽111之间夹设有若干弹簧153。开关板151远离开关板安装槽111的一侧设置有两把手154与凸轮155，凸轮155夹设于两把手154之间，凸轮155的轴心穿插有转轴156，转轴156的两端用卡簧卡住两侧的把手154，使用时，凸轮155有两个位置，一个开位置，一个关位置，当处于开位置时，开关板151在弹簧153作用下弹起，当处于关位置时，在凸轮155作用下，带动若干开关针152一起向夹具下模120所在的方向运动以涨开夹子，松开底壳。
如图2、图3及图4所示，夹具上模110上还开设有若干磁铁调节槽孔112，若干磁铁调节槽孔112与LED显示模组的底壳300上设置的若干磁铁孔位310一一对应设置，且每一磁铁调节槽孔112邻近底壳300的一端为阶梯状结构，以实现相应磁铁13的卡设定位，每一磁铁调节槽孔112内安设有磁铁调节定位结构160，磁铁调节定位结构160包括第一无头螺钉161、压缩弹簧162、磁吸探针163以及调节套164。本实施例的底壳300设置了六个磁铁孔位310，同样的，夹具上模110上开设了六个磁铁调节槽孔112。工作时，每一磁铁调节槽孔112邻近底壳300的一端为阶梯状结构，按下相应磁铁，可将相应磁铁按入阶梯状孔内，实现相应磁铁的卡设定位。第一无头螺钉161主要起到固定调节套的164作用，当调节套164调整好位置后，使调节套164不能自由转动。压缩弹簧162的作用是使磁铁13按压回去定位，定位之后松手复位。磁吸探针163能吸磁铁13。调节套164的作用是能够通过转动调节磁吸探针163的高度，调整好用第一无头螺钉161固定。这样一来，通过每一磁铁调节槽孔112内的磁铁调节定位结构160，可调节所有的磁铁13在一个高度的平面上，进一步确保组装出来的LED显示模组的平整度。
如图2、图3及图5所示，夹具上模110上还开设有若干定位柱调节槽孔113，若干定位柱调节槽孔113与底壳300上设置的若干定位柱孔位320一一对应设置，且每一定位柱调节槽孔113内安设有定位柱调节定位结构170，定位柱调节定位结构170包括第二无头螺钉171、定位针172以及定位柱夹持柱子173。定位针172可调节高低以此调节相应的定位柱14高低，调节好后通过第二无头螺钉171固定定位针172。定位柱夹持柱子173设置于定位柱调节槽孔113邻近夹具下模120的一侧，以对应夹持定位柱14，定位柱夹持柱子14开四个槽，使其具有一定弹性，以夹住定位柱14，但又不至于夹持力过大，导致定位柱14在紫外光固化胶固化后下不来。本实施例的底壳300设置了两个定位柱孔位320，因而，本实施例的定位柱14共2根，一个是圆柱，另一个扁平柱，分别放到底壳300的定位柱孔位320上。
实施例二
如图6所示，本发明实施例二还提出一种LED显示模组的组装方法，该组装方法包括以下步骤：
步骤S110：将LED灯板对应容置于夹具下模的槽体中，且LED灯板的灯面朝向槽体的底壁。
具体地，该定位夹具为实施例一中的定位夹具100，如图2所示，当将LED灯板200对应容置于夹具下模120的槽体121中，且LED灯板200的灯均朝向槽体121的底壁。由于本实施例中的槽体121为矩形槽体，此时，矩形槽体111的四个侧壁恰好将LED灯板200限位在槽体121中，两者的尺寸相互适配。硅胶垫圈125的设置，可实现LED灯板200与槽体121之间的过盈配合，在对LED灯板200进行进一步定位固定的同时，确保LED灯板200的灯面与槽体121之间形成密封空间。
步骤S120：通过真空泵对带有若干抽真空气孔的槽体进行抽真空处理，使得LED灯板与槽体的底壁之间产生负压，以通过大气压将LED灯板的灯缝均匀地压在设于底壁的若干三角凸起上。
具体地，如图2所示，通过真空泵对槽体121进行抽真空处理，使得LED灯板200与槽体121的底壁之间产生负压，以通过大气压将LED灯板200的灯缝均匀地压在相应的三角凸起122上。此时，所有的三角凸起122的尖部在第一平面上，灯珠与三角凸起122的斜面接触，保证灯面都在第二平面上，进而保证LED灯板200在此时具有很高的平整度。
步骤S130：将若干磁铁分别通过相应的磁铁调节定位结构固定在夹具上模邻近夹具下模的一侧，将若干定位柱分别通过相应的定位柱调节定位结构固定在夹具上模邻近夹具下模的一侧。
具体地，如图2至图5所示，本实施例的底壳300设置了六个磁铁孔位310，因而，需将六个磁铁13分别通过相应的磁铁调节定位结构160固定在夹具上模110邻近夹具下模的一侧。磁铁13主要通过相应的磁吸探针163进行吸附固定，并通过相应的调节套164进行高低调节。这样一来，可调节所有的磁铁13在一个高度的平面上，进一步确保组装出来的LED显示模组的平整度。本实施例的底壳300还设置了两个定位柱孔位320，因而，需将两个定位柱14分别通过相应的定位柱调节定位结构170固定在夹具上模110邻近夹具下模120的一侧。定位柱14主要通过相应的定位柱夹持柱子173进行夹持固定，并通过相应的定位针172进行高低调节。
步骤S140：在LED灯板的背面涂抹上紫外光固化胶，并将底壳通过若干底壳夹头固定在夹具上模邻近夹具下模的一侧后，使夹具上模与夹具下模相互扣合连接。
具体地，如图2所示，在LED灯板200的背面涂抹上紫外光固化胶，并将底壳300通过若干底壳夹头140固定在夹具上模110邻近夹具下模120的一侧后，使夹具上模120与夹具下模110相互扣合连接。具体地，在进行底壳300的固定时，先让凸轮155处于关位置，开关板151在凸轮155作用下，带动若干开关针152一起向夹具下模120所在的方向运动以涨开夹子（即底壳夹头140），此时，便可将底壳300的夹持位对准夹子，并使凸轮155切换为开位置，开关板151在弹簧153作用下弹起，若干开关针152收回，若干底壳夹头140将底壳300夹持固定在夹具上模110邻近夹具下模120的一侧。当夹具上模120与夹具下模110相互扣合连接后，底壳300贴附在LED灯板200的背面，同时，若干磁铁13亦分别通过相应的磁铁孔位310贴附在LED灯板200的背面，若干定位柱14亦分别通过相应的定位柱孔位320贴附在LED灯板200的背面。
步骤S150：点亮紫外线灯板，并持续预设时间，以让紫外光固化胶迅速固化，使得底壳、若干磁铁以及若干定位柱分别紧固在LED灯板的背面，进而实现LED显示模组的组装。
具体地，如图2及图3所示，。当夹具上模120与夹具下模110相互扣合连接后，点亮紫外线灯板，并持续预设时间，该预设时间优选为1-2分钟，可使得紫外光固化胶迅速固化，进而使得底壳300、若干磁铁13以及若干定位柱14分别紧固在LED灯板200的背面，进而实现LED显示模组的组装。整个LED显示模组的连接处采用紫外光固化胶进行粘接，更容易提升平整度。最后取下LED显示模组时，可如下操作，先使凸轮155处于关位置，按下开关板主体151，松开底壳300后，取下夹具上模110，再关闭真空泵，取下组装完成的LED显示模组即可。
以上结合附图对本发明的实施方式作了详细说明，但本发明不限于所描述的实施方式。对于本领域的技术人员而言，在不脱离本发明原理和精神的情况下，对这些实施方式进行多种变化、修改、替换和变型，仍落入本发明的保护范围内。
 工业实用性
本发明实施例中的定位夹具及LED显示模组的组装方法，其定位夹具包括相互扣合连接的夹具上模与夹具下模，夹具下模邻近夹具上模的一侧表面设置有矩形槽体，以对应容置LED显示模组的LED灯板；矩形槽体的底壁上凸设有若干三角凸起，以在LED灯板容置于矩形槽体时对应卡设在相应的灯缝中；矩形槽体的底壁设置有若干抽真空气孔，且若干抽真空气孔外接真空泵；夹具上模邻近夹具下模的一侧表面上固设有紫外线灯板。这样一来，在进行LED显示模组组装时，便可将LED灯板对应容置于矩形槽体中，且每一LED灯板的灯面均朝向矩形槽体的底壁。接着，通过真空泵对矩形槽体进行抽真空处理，使得每一LED灯板与矩形槽体的底壁之间产生负压，以通过大气压将每一LED灯板的灯缝均匀地压在相应三角凸起上。此时，所有的三角凸起的尖部在第一平面上，灯珠与三角凸起的斜面接触，保证灯面都在第二平面上，进而保证LED灯板在此时具有很高的平整度。最后，在LED灯板的背面涂抹上紫外光固化胶，并将底壳固定在夹具上模邻近夹具下模的一侧后，使夹具上模与夹具下模相互扣合连接，点亮紫外线灯板，并持续预设时间，以让紫外光固化胶迅速固化，使得底壳紧固在LED灯板的背面，进而实现LED显示模组的组装，即LED灯板与底壳之间紫外光固化胶进行粘接，避免传统方式采用螺钉连接容易导致LED变形影响模组组装平整度的技术问题。可见，本技术方案，其可有效解决传统组装方式难以保证LED显示模组组装平整度的技术问题。因此，具备工业实用性。
