Description

马达振子的焊接工装及焊接方法 技术领域
本发明涉及电声产品技术领域，尤其涉及一种马达振子的焊接工装及焊接方法。
背景技术
二合一动磁式扬声器因具有马达功能，所以需要弹片结构。弹片结构需要使用激光焊接技术，将其焊接到振子的盆架和外壳上。由于盆架底面与外壳不能直接接触，所以需要将振子悬浮到一定高度才能进行焊接。
现有技术中的弹片结构焊接工装，主要定位振子的Z轴高度。在使用过程中发现，其存在以下弊端：在Z轴方向的定位，很容易遮挡焊接弹片结构的激光焊接设备，造成焊接不良；而且由于二合一扬声器产品的结构复杂，需要结构复杂繁琐的工装，进一步增加了定位的难度，还增加了成本和时间；而且现有的焊接工装一旦定型，就很难再进行调整，不便于产品DOEs(试验设计)的进行。
发明内容
针对上述不足，本发明所要解决的第一个技术问题是：提供一种马达振子的焊接工装，该工装具有结构简单、体积小、成本低以及操作方便的优点。

优选方式为，所述工装磁铁的数量与所述马达磁铁的数量相同。
优选方式为，所述支撑部件为机械臂。
优选方式为，所述工装磁铁为永久磁铁。
优选方式为，所述工装磁铁为电磁铁。
基于同一发明构思，本发明所要解决的第二个技术问题是：提供一种马达振子的焊接方法，该方法使振子定位快，节约时间，提高装配精度和生产效率。
为解决上述技术问题，本发明的技术方案是：
一种马达振子的焊接方法，包括以下步骤：
步骤一：将所述马达振子放在马达壳体上，将上述的马达振子的焊接工装置于所述马达振子的上方，并使得位于所述支撑部件下部的所述工装磁铁与位于所述振子端部的所述马达磁铁相对应；
步骤二：给所述马达磁铁的音圈通入电流；
步骤三：调整所述支撑部件和所述振子之间的距离，和/或调整通入所述马达磁铁的音圈的电流大小，使得所述振子悬停在所述马达壳体上方的合适位置；
步骤四：采用焊接设备将弹片的两端分别焊接在所述振子与所述马达壳体上。
优选方式为，所述马达振子为动磁式扬声器的振子，所述振子包括设置所述马达磁铁的盆架，以及设在所述马达磁铁中间的磁铁。
优选方式为，各所述马达磁铁的所述音圈的中间各设置一衔铁，所述衔铁根据通过所述音圈的电流方向的变化而改变自身的磁化方向。
优选方式为，所述振子还包括设在各所述音圈上的导磁部件，各所述导磁部件覆盖对应的所述音圈的上表面；位于两侧的两所述音圈上的所述导磁部件还覆盖了所述音圈的外侧面。
优选方式为，所述马达壳体的底部向所述马达壳体的两端各伸出一固定部，所述固定部上设有给所述音圈输入电流的FPCB(柔性印刷线路板)。
一种马达振子的焊接方法，包括以下步骤：
步骤一：将所述马达振子放在马达壳体上，将上述的马达振子的焊接工装置于所述马达振子的上方，并使得位于所述支撑部件下部的所述工装磁铁与位于所述振子端部的所述马达磁铁相对应；
步骤二：给所述马达磁铁的音圈通入电流，和/或给所述工装磁铁的音圈通入电流；
步骤三：调整所述支撑部件和所述振子之间的距离，和/或调整通入所述马达磁铁的音圈的电流大小，和/或调整通入所述工装磁铁的音圈的电流大小，使得所述振子悬停在所述马达壳体上方的合适位置；
步骤四：采用焊接设备将弹片的两端分别焊接在所述振子与所述马达壳体 上。
采用上述技术方案后，本发明的有益效果是：由于本发明的马达振子的焊接工装及焊接方法，其中马达振子的焊接工装包括支撑部件及安装在其上的工装磁铁，工装磁铁的数量和安装位置均与待焊接弹片的动磁式扬声器上的音圈相适配，且工装磁铁的磁化方向相同且均为竖向。那么使用本发明的磁悬浮式焊接工装焊接弹片时，在支撑部件的支撑下工装磁铁与振子上的各音圈相对设置，然后通过FPCB给音圈内输入电流，调整电流的方向，使音圈成为与工装磁铁相互吸引的电磁铁，以便将振子吸起来悬浮。调整支撑部件和振子之间的距离，和/或者调整音圈内电流的大小，均可调整工装磁铁和音圈之间的吸力，去调整振子的悬浮位置，将振子快速的定位。因本发明的磁悬浮式焊接工装所占用的空间小，使用于焊接的激光设备不被遮挡，从而提高了焊接的精度。而且本发明的焊接工装还方便了DOE验证的进行，节约了时间，降低了成本。
由于音圈的中间设有衔铁，在步骤一中，工装磁铁与音圈中间的衔铁相对设置；使整个振子和工装磁铁之间的引力对称，便于调整过程平衡进行。
由于动磁式扬声器包括两FPCB，两FPCB分设在壳体的两侧，且FPCB的一端位于壳体向两侧伸出的固定部上；方便了各音圈之间连接关系的调整。
综上所述，本发明的马达振子的焊接工装与现有技术相比，解决了现有技术中弹片结构焊接工装定位Z轴，导致定位难度大的技术问题；而本发明的马达振子的焊接工装，通过调整音圈电流大小来调整振子悬空位置，使振子悬空定位更加容易，节约成本和时间。

具体实施方式
为了使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本发明进行进一步详细说明。应当理解，此处所描述的具体实施例仅 仅用以解释本发明，并不用于限定本发明。
实施例一：
如图1和图2所示，一种马达振子的焊接工装，包括支撑部件，本实施例的支撑部件优选机械臂502；以及安装在机械臂502下部的工装磁铁500。分别位于机械臂502两端部的两块工装磁铁500，分别与位于马达振子3两端部的两块马达磁铁相对应(对齐)设置，从而产生相互之间的磁作用力；马达磁铁为电磁铁，工装磁铁500和马达磁铁都在Z轴方向磁化均为(竖向)，从而相互吸引。工装磁铁500的数量不限于此。
本发明的工装磁铁500的数量与马达磁铁的数量相同，以便在进行焊接时，工装磁铁500和马达磁铁一对一地相互吸引，将马达振子3吸起来。
本实施例所使用的工装磁铁500为永久磁铁，而且永久磁铁的磁极可以是朝向音圈34侧的磁极为N极，远离音圈34的一侧磁极为S极，当然也可以反过来。无论工装磁铁500的极性如何设置，只要输入音圈34内的电流的方向使音圈34成为电磁铁后，电磁铁的磁化方向与工装磁铁500的磁化方向相同即可。
如图1和图2所示，本发明还涉及一种马达振子的焊接方法，包括以下步骤：
步骤一：将马达振子3放在马达壳体10上，将上述的马达振子3的焊接工装50置于马达振子3的上方，并使得分别位于机械臂502两端的两块工装磁铁500分别与位于振子3两端的两块马达磁铁相对应；本实施例的马达磁铁包括扁平结构的音圈34，以及插在音圈中间的衔铁36；当然马达磁铁不限本实施例所列举的结构。
步骤二：给马达磁铁的音圈34通入电流；具体为：图示中⊙和⊕代表音圈34内的电流方向，⊙表示电流方向垂直于纸面向外，⊕表示电流方向垂直于纸面向内。音圈34中通入图中所示方向的电流时，按照右手定则，位于左侧的音圈34的磁场方向为箭头60所示的方向，右侧的音圈34的磁场方向为箭头62所示的方向。也就是两音圈34的上端均为N极，下端为S极，若我们让工装磁铁500的下端为S极，上端为N极，则工装磁铁500和音圈34之间产生向上的吸力，如箭头64和66所示的方向，吸力将振子3吸起来悬浮。
步骤三：调整机械臂205和振子3之间的距离，和/或调整通入马达磁铁的 音圈34的电流大小，使得振子3悬停在马达壳体10上方的合适位置；
步骤四：采用焊接设备将弹片39的两端分别焊接在振子3与马达壳体10上。
如图1和图2所示，本实施例的马达振子，为二合一动磁式扬声器中的振子，振子3包括两个或三个音圈34；振子3还包括设在两音圈34之间的磁铁38，该磁铁38与扬声器的马达功能所配置的马达的磁铁相排斥，保持平衡。同时本实施例的动磁式扬声器包括两FPCB(柔性印刷线路板)40，两个FPCB 40分设在马达壳体10的两侧，且FPCB 40的一端位于马达壳体10向两侧伸出的固定部上。因FPCB 40设有位于马达壳体10外侧的部分，使内部的音圈34与外部电路连接方便，各音圈34之间的连接关系调整也方便。
如图1和图2所示，振子还包括设在马达磁铁的盆架30，马达磁铁包括音圈34，两个音圈34的中间各设置一衔铁36，衔铁36根据通过音圈34的电流方向的变化而改变自身的磁化方向。而且两个音圈34上均设有导磁部件32，各导磁部件32覆盖对应的音圈34的上表面；位于两侧的两音圈34上的导磁部件32还覆盖了音圈34的外侧面。当然若是振子包括三个音圈34，则设有三个导磁部件32。
另外本发明的支撑部件不限本例所列举的机械臂502，只要能够按照上述方式安装工装磁铁500即可。
实施例二：
本实施例与实施例一基本相同，不同之处在于：
如图1和图2所示，本实施例的焊接工装50，其机械臂502上设置的工装磁铁500为电磁铁。也就是工装磁铁500被通入电流后，成为电磁铁。
一种马达振子的焊接方法，包括以下步骤：
步骤一：将马达振子3放在马达壳体10上，将马达振子3的焊接工装50置于马达振子3的上方，并使得分别位于机械臂502两端的两块工装磁铁500分别与位于振子3两端的两马达磁铁相对应。本实施例的马达磁铁包括扁平结构的音圈34，以及插在音圈中间的衔铁36；当然马达磁铁不限本实施例所列举的结构。
步骤二：给马达磁铁的音圈34通入电流，和/或给工装磁铁500的音圈通 入电流；使马达磁铁成为电磁铁，使工装磁铁500成为电磁铁，通过控制电流的方向，让马达磁铁和工装磁铁相吸引。
步骤三：调整机械臂502和振子3之间的距离，和/或调整通入马达磁铁的音圈34的电流大小，和/或调整通入工装磁铁500的音圈的电流大小，使得振子3悬停在马达壳体10上方的合适位置；
步骤四：采用焊接设备将弹片39的两端分别焊接在振子3与马达壳体10上。
由上面两个实施例可知，本发明的马达振子的弹片焊接的原理，就是将音圈34通电形成电磁铁，通过调整音圈34电流大小、焊接工装50与音圈34之间的距离，调整振子3与工装磁铁500之间的吸引力，进而调整振子3悬空的位置。而本发明的磁悬浮焊接工装与现有技术相比具有以下优点：
1、不使用工装定位Z轴高度，而是通过调整音圈34的电流来调整高度，精确度较高。
2、通过改变电流大小可以很方便地改变悬空位置，相对于工装定位更容易进行DOE的验证，节约成本和时间。
3、相对于工装定位，磁悬浮定位方式工装结构占用空间较小，不会影响激光焊接。
以上所述本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内所作的任何修改、等同一种马达振子的焊接工装及焊接方法结构的改进等，均应包含在本发明的保护范围之内。
