图3和图4分别为本发明的紫外线照射装置的侧视图和紫外线照射装置的俯视图。
如图3所示，本发明的紫外线照射装置用于发光二极管封装，该紫外线照射装置包括：壳体1和腔体2，其中，壳体1为密闭的，在壳体1内设有待封装的 发光二极管3，发光二极管3的下方设有能在壳体1内移动的紫外线罩体4；紫外线罩体4的下方设有紫外线灯源5，腔体2为密封的，且与壳体1相连通，腔体2设于壳体1的一侧，腔体2内设有能传送发光二极管3的第一滚动单元21，腔体2的两端分别设有第一门22和第二门23，腔体2还分别与抽气单元6和第一气体气源7相连通。
具体的，在本发明中，由于机发光二极管封装需在N2环境中进行，在壳体1内，充满氮气，紫外线罩体4通过第二滚动单元11在壳体1内移动，在一具体实施例中，第二滚动单元11由多个滚轴111构成，通过滚轴111的转动来带动紫外线罩体4在壳体1内的移动。
具体的，在本发明中，第一气体为氮气，抽气单元6采用一抽气泵装置，在腔体2内，第一滚动单元21同样由滚轴211构成，通过滚轴211的转动来带动紫外线罩体4在腔体2内的移动。进一步地，第一滚动单元21与第二滚动单元11相对设置以构成能传送紫外线罩体4的传送单元，在本实施例中，滚轴211与滚轴111相对设置，从而实现发光二极管3能够方便地从壳体1内输送到腔体2内或从腔体2内输送到壳体1中。
壳体1的左侧设有开口13，腔体2通过开口13与壳体1相连通，第二门23能够控制开口13处于打开状态或封闭状态。
如图3和图4所示，第一滚动单元21远离壳体1的一端设有罩体止挡件23，罩体止挡件23能在腔体2内上下移动及左右移动，以防止将紫外线罩体4从壳体1内传送到腔体2时紫外线罩体4撞到腔体2的侧壁，即能够有效地保护紫外线罩体4。
保护紫外线罩体4包括罩体边框43和罩体有效区44，其结构为本领域所熟知，在此不再赘述。
罩体止挡件23靠近壳体1的一端设有能夹持紫外线罩体4的夹持件(图中未示出夹持件)。
进一步地，第二滚动单元11远离腔体2的一端设有罩体止挡件15，罩体止挡件15能在壳体1内上下移动和左右移动。在一实施例中，罩体止挡件15靠近腔体2的一端设有能夹持紫外线罩体4的夹持件(图中未示出夹持件)。
进一步地，如图4所示，在壳体1内，紫外线罩体4靠近腔体2的一端设有定位销41，紫外线罩体4的两侧设有导轮42，在腔体2内同样设于导轮42。
使用本发明的紫外线照射装置更换紫外线罩体4的过程如下：
需要更换紫外线罩体4时，第一门22和第二门23均处于关闭状态，抽气单元6抽除腔体2内的气体，然后第一气体气源7向腔体2内充入氮气，使腔体2内为氮气环境，打开第二门23，打开罩体止挡件23的夹持件，向右移动罩体止挡件23，再向下移动罩体止挡件23，同时转动定位销41使其向下移动，启动驱动***，使滚轴111和滚轴211转动，滚轴111转动带动紫外线罩体4从壳体1内向腔体2内移动，当紫外线罩体4移动到腔体2内以后，关闭第二门23，关闭驱动***，打开罩体止挡件15上的夹持件以夹持住紫外线罩体4，移动罩体止挡件15使紫外线罩体4与第一门22相对，再次打开罩体止挡件15上的夹持件使紫外线罩体4脱离该夹持件，并向下移动罩体止挡件15，打开第一门22及驱动***，驱动***使滚轴211转动，滚轴211带动紫外线罩体4从腔体2内移出，即取出原来的紫外线罩体4，从第一门22中向腔体2内装入新的紫外线罩体4，关闭第一门22，抽气单元6抽除腔体2内的气体，然后第一气体气源7向腔体2内充入氮气，打开第二门23，打开驱动***，驱动***使滚轴111和滚轴211转动，从而带动紫外线罩体4从腔体2内移动到壳体1内，待紫外线罩体4传送到壳体1内后，关闭第二门23，滚轴111将紫外线罩体4传送到指定位置后，罩体止挡件23的夹持件打开，并向上移动罩体止挡件23，再向左移动罩体止挡件23，同时转动定位销41使其向上移动，从而实现待紫外线罩体4的一端由定位销41定位，另一端被罩体止挡件23所夹持固定，从而实现将紫外线罩体4稳定地设置在壳体1内的工作位置，即完成紫外线罩体4的更换。
在本发明中，腔体2体积小，配合抽气单元抽气和第一气体气源充入氮气动作，腔体2内变为可生产的氮气环境耗时间为20分钟～30分钟，远小于正常更换紫外线罩体恢复机台氮气环境所需的6h，大量节省紫外线罩体的更换时间，从而实现提高产能的效果。
上述技术方案只是本发明的一种实施方式，对于本领域内的技术人员而言，在本发明公开了应用方法和原理的基础上，很容易做出各种类型的改进或变形，而不仅限于本发明上述具体实施方式所描述的方法。虽然已经参考优选实施例对本发明进行了描述，但在不脱离本发明的范围的情况下，可以对其进行各种改进并且可以用等效物替换其中的部件。尤其是，只要不存在结构冲突，各个实施例中所提到的各项技术特征均可以任意方式组合起来。本发明并不局限于文中公开 的特定实施例，而是包括落入权利要求的范围内的所有技术方案。
