为使本发明实施例的目的、 技术方案和优点更加清楚, 下面将结合本发 明实施例的附图,对本发明实施例的技术方案进行清楚、 完整地描述。显然, 所描述的实施例是本发明的一部分实施例, 而不是全部的实施例。 基于所描 述的本发明的实施例, 本领域普通技术人员在无需创造性劳动的前提下所获 得的所有其他实施例, 都属于本发明保护的范围。
如图 1中, 加热器 4和定位平台 1可以设置在操作控制器 3上。 定位平 台 1上可以放置例如液晶面板等待处理件 7, 并且可以将待处理件 7探出定 位平台 1 , 使待处理件 7上的 IC 8位于能够被加热器 4加热的位置(贴附或 靠近加热器 4均可) , 例如位于加热器 4的上方。 加热器 4例如可以通过电 阻加热、红外线等加热方式等实现。操作控制器 3可以包括中央处理器( CPU ) 或数字信号处理器(DSP )等。
操作控制器 3能够控制加热器 4的开启和关闭, 还可以控制加热器 4的 加热温度。当操作控制器 3控制加热器 4开启时,加热器 4能够对 IC 8加热, 经过一段时间的加热后, 将 IC 8固定在待处理件 7上的胶(例如各向异性导 电胶)被软化, 因此可以用工具将 IC 8从待处理件 7上取下, 实现 IC 8的去 除。 以是设置有控制程序的机械手,只要能够将 IC 8从待处理件 7上顺利剥离即 可。
为了严格保证待处理件 7在定位平台 1上的位置固定, 还可以将定位平 台 1设置为中空, 并在定位平台 1的表面设置一个或一个以上的吸附口 6, 并将真空器(图中未显示, 例如可以设置于操作控制器 3内部或独立设置) 与定位平台 1相连。 操作控制器 3可以控制真空器开启, 真空器则使得定位 平台 1内部出现负压, 使待处理件 7被吸附在吸附口 6上。 这样, 待处理件 7就被固定在定位平台 1上, 便于准确、 快捷地实现待处理件 7上的 IC 8的 去除。
当然, 为了保证将待处理件 7固定在定位平台 1上, 也可以采用其它多 种多样的设置方式, 例如在定位平台 1上设置磁性件, 由该磁性件将待处理 件 7吸附在定位平台 1上。
为了方便后续处理, 还可以设置如图 2所示的去除液输出器 2, 并且设 置与去除液输出器 2相连的去除液容器 5。 去除液输出器 2可以设置在操作 控制器 3上方, 由操作控制器 3控制去除液输出器 2的开启和关闭。 当操作 控制器 3控制除液输出器 2开启时, 去除液容器 5中的去除液能够从去除液 输出器 2中滴落到待处理件 7上设置有 IC 8的区域,待处理件 7上因加热而 软化的胶能够被去除液去除, 使待处理件 7保持洁净, 有利于针对待处理件 7的后续处理。
具体而言,可以在去除液输出器 2上设置如图 3所示的去除液输出口 9, 去除液输出口 9的数量可以为一个或一个以上, 去除液容器 5中的去除液能 够从去除液输出口 9中流出或喷出。 图中去除液输出口 9按直线排列, 但是 例如也可以按 Z字形等方式排列。 操作控制器 3还可以控制加热器 4和 /或定位平台 1的横向移动,其控制 方式例如可以是通过滑轨控制或通过活塞控制等, 即本发明的实施例还可以 包括控制加热器 4和 /或定位平台 1进行横向移动的横向移动控制机构,例如 包括滑轨或活塞等。 这样, 加热器 4和定位平台 1之间的距离等位置关系可 以变动, 进行 IC去除时的自动化、 机械化程度更高。
另外, 可以在操作控制器 3上设置如图 4所示的加热器高度调节器 10, 当然也可以在操作控制器 3上设置如图 4所示的定位平台高度调节器 11。例 如, 加热器高度调节器 10是能够调节加热器 4的高度的纵向位移控制机构, 定位平台高度调节器 11是能够调节定位平台 1的高度的纵向位移控制机构, 加热器高度调节器 10和定位平台高度调节器 11可以包括例如齿轮、 丝杠等 传动机构, 并且例如包括步进马达等驱动结构。 在包含加热器高度调节器 10 和 /或定位平台高度调节器 11的基础上, 可以灵活地控制相应的加热器 4和 / 或定位平台 1的高度, 这样就能控制加热器 4与定位平台 1之间的高度位置 关系, 进行 IC去除时的自动化、 机械化程度更高。
进一步的, 操作控制器 3还可以控制加热器高度调节器 10和 /或定位平 台高度调节器 11的横向移动,其控制方式例如可以是通过滑轨控制或通过活 塞控制等, 即本发明的实施例还可以包括控制加热器高度调节器 10和 /或定 位平台高度调节器 11 进行横向移动的横向移动控制机构, 包括滑轨或活塞 等。 这样, 加热器高度调节器 10上的加热器 4和定位平台高度调节器 11上 的定位平台 1之间的距离等位置关系可以变动,进行 IC去除时的自动化、机 械化程度更高。
再有, 无论是否设置有加热器高度调节器 10、 定位平台高度调节器 11 , 操作控制器 3上所设置的加热器 4和 /或定位平台 1的数量均可为一个或一个 以上, 以应对大量去除 IC的生产要求。
在实际应用中, 基于上述描述, 可以进行如图 4、 图 5所示的设置。 请 注意, 图 4、 图 5中省略了与去除液相关的器件, 与去除液相关的技术已在 前述内容中描述, 在此不再赘述。 结合图 4、 图 5可知, 操作控制器 3上设 置有加热器高度调节器 10、 定位平台高度调节器 11 , 加热器高度调节器 10 上按不同高度逐层设置有多个加热器 4,定位平台高度调节器 11上按不同高 度逐层设置有多个定位平台 1 , 定位平台 1上设置有吸附口 6用于固定待处 理件。 通常一个加热器 4与一个定位平台 1相对应, 用于去除 IC。
操作控制器 3能够控制加热器高度调节器 10和 /或定位平台高度调节器 11的横向移动, 加热器高度调节器 10能够控制加热器 4的纵向移动, 定位 平台高度调节器 11能够控制定位平台 1的纵向移动。
可以在每个定位平台 1上放置待处理件 7, 并且通过加热器 4和 /或定位 平台 1合理的移动, 使各定位平台 1对应的加热器 4位于能够加热相应的待 处理件 7上的 IC的位置, 进而去除 IC。
综上所述可见, 本发明实施例的去除 IC的装置,使待处理件的加热、 固 定实现更多的机械化、 自动化, 减少工作人员的手工参与, 能够明显减少操 作时间, 有效提高处理效率。 并且可以有效避免 IC去除过程中的玻璃破碎, 也不会造成工作人员烫伤, 还能够同时处理不同尺寸的产品。
以上所述仅是本发明的示范性实施方式, 而非用于限制本发明的保护范 围, 本发明的保护范围由所附的权利要求确定。
