Description

一种IV、EL双面测试传送装置 技术领域
本发明涉及太阳能电池检测设备技术领域，具体涉及一种IV、EL双面测试传送装置。
背景技术
太阳能电池组件在制作过程中会产生一些隐性的缺陷和显性缺陷，如硅材料错位、断栅、PN结杂质、虚焊、破片等，有些缺陷用肉眼不能检测出来，需靠专门的检测设备进行检测，目前检测太阳能电池缺陷的设备为EL检测机，对太阳能电池组件电性能进行检测的设备为IV检测机，与之配套的传送装置通常为直线式传送带，将待检测组件放置于直线式传送带上，待检测组件在EL检测机工位检测后在转移到IV检测机工位，全部检测完成后再转移到下料工位等待下料，不仅只能对太阳能电池组件的上表面进行检测，同时占用空间大、载具的流转效率低，由此大大降低了太阳能组件的检测效率。
有鉴于此，实有必要开发一种双面测试传送装置，用以解决上述问题。
发明内容
本发明要解决的技术问题是提供一种IV、EL双面测试传送装置，利用四工位转台提高空间的利用率，降低设备占地面积，提高太阳能组件在各个工位间转移的效率，同时实现对太阳能组件上下表面同时检测。

具体实施方式
下面结合附图和具体实施例对本发明作进一步说明，以使本领域的技术人员可以更好地理解本发明并能予以实施，但所举实施例不作为对本发明的限定。
参照图1所示，为本发明的一种IV、EL双面测试传送装置的实施例，该装置包括机台10；与所述机台10固定连接的旋转驱动组件20；与所述旋转驱动组件20转动连接的转盘30，因此，上下料及测试装置只需绕转盘30一周设置，提高了空间利用效率，降低了设备占地面积。本实施例中，所述机台10上沿所述转盘30的旋转方向依次设置有上料工位11、EL测试工位12、IV测试工位13和下料工位14，所述转盘30四周均匀间隔地向外连接有四个载具40，所述转盘30在旋转驱动组件20的驱动下带动所述载具40分别与上料工位11、EL测试工位12、IV测试工位13、及下料工位14对应，载具40向外延伸，伸出了转盘30的范围，一方面，无需设置大转盘30，节约材料，减轻转盘30的重量，方便驱动，另一方面，由于测试装置从上下两个方向贴近载具40，向外延伸的载具40能够防止下方的测试部件与转盘30下方的旋转驱动组件20干涉。为使上下方的测试部件均能够接触载具40上的太阳能组件50，所述载具40为中间镂空的框架结构，所述载具40侧边向内延伸连接有若干吸盘41，通过吸盘41实现对太阳能组件50的固定和支撑，太阳能组件50的上下表面均暴露在外，使得测试组件能够同时从上下方接触太阳能组件50，从而对其进行双面测试。由于太阳能组件50在放置于载具40上时需要略微下压太阳能组件50，保证太阳能组件50与吸盘41的充分接触才能确保为吸盘41吸附固定太阳能组件50，但载具40中间镂空，为防止太阳能组件50下压的力度过大损坏太阳能组价，所述载具40上表面四周设置有一圈垫板42，当太阳能组件50接触到垫板42后无法被继续下压，形成对太阳能组件50的保护，且所述垫板42的厚度小 于所述吸盘41的高度，保证太阳能组件50能够与吸盘41充分接触。本实施例中为保证位于载具40下方的测试组件有足够的运动空间，所述旋转驱动组件20下端与所述机台10连接，此时，转盘30与机台10之间有一个旋转驱动组件高度的距离。
参照图2所示，为本发明载具40结构爆炸图，所述载具40包括外框43和底板44，所述外框43和底板44之间存在空气流道，所述空气流道连通所述吸盘41，所述空气流道的抽气口45位于所述载具40与所述转盘30连接的一端，多个吸盘41通过一个抽气口45进行抽气实现对太阳能组件50的固定，一方面，吸盘41不直接连接真空管道，使得测试组件在从上下两个方向靠近载具40上的太阳能组件50时没有任何干涉，另一方面，尽量少的抽气口45同样使得真空管道的数量减少，使得设备更加整齐美观。
参照图3所示，为本发明旋转驱动组件结构示意图，由于载具40在转盘30的带动下持续转动，为保证转动过程中连接载具40的真空管道不与其他组件干涉，所述旋转驱动组件包括DD电机21，一方面DD电机21输出力矩大，保证驱动转盘30和载具40的转动，另一方面DD电机21为管状，真空管道能够从DD电机21的中心穿过，从而在转盘30和载具40转动时不会与机台10或其他组件干涉，进一步的，为保证真空管道随转盘30一同转动并能够传输气体实现吸盘41的真空吸附固定，所述机台10下方设置有气动滑环46，气动滑环46设置在机台10下方不会影响上方转盘30的转动及测试组件的工作，而后真空管道穿过所述DD电机21和机台10分别连通所述抽气口45和气动滑环46，实现载具40和真空管道的360°转动。
参照图4所示，为本发明另一实施例驱动组件结构示意图，进一步的，本实施例中为在转动过程中不拉扯真空管道而带动气动滑环46转动，所述旋转驱动组件还包括驱动杆22，所述驱动杆22穿过DD电机21且两端分别连接所述气动滑环46和DD电机21的转子，驱动杆22由DD电机21驱动，驱动杆22带动气动滑环46同步转动，保证气动滑环46的出气口与载具40的抽气口45 对应，本实施例中，所述驱动杆22通过限位盘23与转盘30和DD电机21相连，所述限位盘23四周设置有供所述真空管道穿过的限位槽24，真空管道仅能从限位槽24的位置穿过，保证真空管道的整齐。更进一步的，所述驱动杆22侧边设置有固定接头47，所述真空管道穿过所述固定接头47与所述气动滑环46连接，真空管道贴合驱动杆22表面而不会散开，不会造成管道的混乱。
以上所述实施例仅是为充分说明本发明而所举的较佳的实施例，本发明的保护范围不限于此。本技术领域的技术人员在本发明基础上所作的等同替代或变换，均在本发明的保护范围之内。本发明的保护范围以权利要求书为准。
