Description

一种连续镀化方法 技术领域
本发明涉及镀化技术领域，更具体地，涉及一种连续镀化方法。
背景技术
一些金属元器件通常采用冲压的方式连续成型。例如，用于电连接的弹片。在制作时，弹片通过冲压的方式在连料带上进行成型。连料带通常为金属板材，例如不锈钢板或者镀锌板等。连料带具有设定的纹理，以提高弹片在设定方向上的结构强度。例如，纹理的丝向与料带的延伸方向平行。丝向与连料带的进料方向平行。为了提高弹片的使用寿命，弹片的主体方向通常平行于丝向。这要求在进行冲压时，弹片的主体方向平行于连料带的进料方向。
弹片沿主体方向的不同部位通常需要镀化不同的金属层，以改善弹片的导电性能。例如，弹片的下端镀镍，中间部位镀金。然而，由于连料带上的弹片在竖直方向上几乎没有高度差，故在进行镀镍时，弹片的整体都浸入镀化液体中。这样，需要镀金的位置也被镀上了镍。这种方式无法满足在不同位置镀化不同种金属的要求。
因此，需要提供一种新的技术方案，以解决上述技术问题。
发明内容
本发明的一个目的是提供一种连续镀化方法的新技术方案。
根据本发明的第一方面，提供了一种连续镀化方法。该方法包括：将多个待镀化产品连接到第二连料带上，所述待镀化产品的主体方向与第二连料带的延伸方向成设定夹角，以使所述待镀化产品沿各自主体方向的不同位置在垂直于所述延伸方向上形成高度差；通过所述第二连料带，将所述多个待镀化产品的远离所述第二连料带的第一位置浸入第一金属镀液 中，以镀化第一金属层；在所述多个待镀化产品的位于各自第一位置与所述第二连料带之间的第二位置上镀化第二金属层。
可选地,所述多个待镀化产品向所述第二连料带的同一侧伸出，并且主体方向与所述第二连料带的延伸方向的夹角相同。
可选地,所述待镀化产品的主体方向与所述第二连料带的延伸方向垂直。
可选地,所述待镀化产品的上端与预切料连接，所述预切料被连接到所述第二连料带上。
可选地,所述预切料通过粘结、铆接、焊接和卡接中的至少一种方式固定在所述第二连料带上。
可选地,所述预切料与所述第二连料带之间形成多个固定点。
可选地,所述预切料包括位于所述待镀化产品沿延伸方向的两侧的连接部，所述连续镀化方法还包括去除所述连接部的至少局部，以露出所述第一位置。
可选地,所述多个待镀化产品两两对称地设置在所述第二连料带的两个工作面上。
可选地,通过电镀或者化学镀镀化所述第一金属层。
可选地,通过点镀的方式镀化所述第二金属层。
根据本公开的一个实施例，待镀化产品被固定在第二连料带上，并且主体方向与第二连料带的延伸方向成设定夹角。这样，待镀化产品的不同位置在垂直于第二连料带延伸方向上形成高度差。在进行镀化时，靠近最下端的第一位置浸入第一金属镀液中进行镀化，而第二位置位于第一金属镀液的液面之上，从而使得第二位置不会镀上第一金属，避免了不同镀化步骤之间的相互影响。
此外，该镀化方法的操作简单，适用于大规模生产。
通过以下参照附图对本发明的示例性实施例的详细描述，本发明的其它特征及其优点将会变得清楚。

具体实施方式
现在将参照附图来详细描述本发明的各种示例性实施例。应注意到：除非另外具体说明，否则在这些实施例中阐述的部件和步骤的相对布置、数字表达式和数值不限制本发明的范围。
以下对至少一个示例性实施例的描述实际上仅仅是说明性的，决不作为对本发明及其应用或使用的任何限制。
对于相关领域普通技术人员已知的技术、方法和设备可能不作详细讨论，但在适当情况下，所述技术、方法和设备应当被视为说明书的一部分。
在这里示出和讨论的所有例子中，任何具体值应被解释为仅仅是示例性的，而不是作为限制。因此，示例性实施例的其它例子可以具有不同的值。
应注意到：相似的标号和字母在下面的附图中表示类似项，因此，一旦某一项在一个附图中被定义，则在随后的附图中不需要对其进行进一步讨论。
根据本发明的一个实施例提供了一种连续镀化方法。连续镀化适用于电气元件，尤其是导电零件的金属层的镀化。镀化可以采用电镀或者化学镀。在上述两种方式中，待镀化产品需要同时或者顺次浸渍到镀液中，能够进行大面积、复杂表面状况的镀化，并且能够保证电镀的均匀性，适合大规模生产。待镀化产品可以是弹片14、插头、集流体等。下面以弹片14为例，进行说明。弹片14通常采用冲压的方式进行一体成型。
例如，第一连料带11经过冲压机床进行冲压，以形成连料单元15。连料单元15包括待镀化产品(例如，弹片14)和与待镀化产品的上端连接的预切料13。弹片14在进行完弯折、电镀、嵌件注塑等工序后形成功能部件，并从预切料13上切下来，以备使用。
弹片14的主体方向与第一连料带11的纹理的丝向平行，以保证弹片14具有足够的结构强度。纹理为在第一连料带和第二连料带上开设的线槽。丝向即线槽的方向。线槽可以是直线、波浪线等。弹片14可以是针形、U形、连续弯折形状等，本领域技术人员可以根据实际需要进行设置。当然，弹片的主体方向与丝向之间的角度可以根据实际需要进行设置，不限于相互平行。
在该例子中，如图1所示，该连续镀化方法包括：
S1、将多个待镀化产品连接到第二连料带12上。待镀化产品的主体方向与第二连料带12的延伸方向成设定夹角，以使待镀化产品沿各自主体方向的不同位置在垂直于延伸方向上形成高度差。
在此，多个待镀化产品沿第二连料带12的延伸方向并列设置。可以直接将弹片14连接到第二连料带12上；也可以是，弹片14通过预切料13连接到第二连料带12上，即预切料13固定在第二连料带12上。例如，预切料13通过粘结、铆接、焊接和卡接中的至少一种方式固定在第二连料带12上。上述固定方式的连接牢固，操作容易。弹片14的主体方向与第二连料带12的延伸方向成设定夹角，这使得弹片14的不同位置在垂直于第二连料带12延伸方向上形成高度差。本领域技术人员可以理解的是，夹角大于0°小于或等于180°。
优选地，预切料13与第二连料带12之间形成多个固定点。如图5所 示，例如，通过铆接的方式将弹片14的预切料13固定在第二连料带12上，并形成多个铆孔19。多个铆孔19能有效限定弹片14的位置，防止弹片14出现转动和偏移。这样，弹片14与第二连料带12的固定更牢固，并且弹片14的主体方向与第二连料带12的夹角更准确。
S2、通过第二连料带，将多个待镀化产品的的远离第二连料带12的第一位置16浸入第一金属镀液中，以镀化第一金属层。该第一位置16凸出于第二连料带12，以便于浸入第一金属镀液中。在该步骤中，第一位置16浸入第一金属镀液中，而由于其他需要进行镀化的位置与第一位置16存在高度差，例如均高于第一位置16，故不会浸入第一金属镀液中。
在电镀时，如果第一位置16与第一金属镀液的液面存在设定的角度，可以将第二连料带12整体进行倾斜，以便于第一位置16能浸入液面以下。
S3、在多个待镀化产品的位于各自第一位置16与第二连料带12之间的第二位置17上镀化第二金属层。优选地，通过点镀的方式镀化第二金属层。在点镀时，第二金属镀液被喷到第二位置17。通过这种方式，能使镀化的位置更准确，精度更高。本领域技术人员可以根据实际需要选择第一金属层和第二金属层的材质。例如，第一金属层为镍层，第二金属层为金层。
由于不同的镀化步骤之间不会相互影响，故在其他示例中，还可以首先在第二位置17镀化第二金属层，例如采用点镀的方式进行镀化；然后在第一位置16镀化第一金属层，例如采用电镀或者化学镀进行镀化。这样同样能够在弹片14的不同位置形成多个镀层。
在其他示例中，弹片14上的金属镀层不限于两个，本领域技术人员可以根据实际需要进行设置。
在本发明实施例中，待镀化产品被固定在第二连料带12上，并且主体方向与第二连料带12的延伸方向成设定夹角。这样，待镀化产品的不同位置在垂直于第二连料带12延伸方向上形成高度差。
在进行镀化时，靠近最下端的第一位置16浸入第一金属镀液中，以进行镀化，而第二位置17位于第一金属镀液的液面之上，从而使得第二位置17不会镀上第一金属，避免了不同镀化步骤之间的相互影响。该方法能 够实现待镀化产品在不同位置镀化不同的镀层。
此外，待镀化产品的主体方向与纹理的丝向平行，这使得待镀化产品的结构强度更高。
此外，该镀化方法的操作简单，适用于大规模生产。
在一个例子中，如图4所示，多个待镀化产品向第二连料带12的同一侧伸出，并且主体方向与第二连料带12的延伸方向的夹角相同。例如，多个弹片14的伸出方向相同，并且沿相同的角度倾斜。这使得在进行镀化时，多个弹片14的进料方向一致，保证了镀化效果的一致性。
优选地,待镀化产品的主体方向与第二连料带12的延伸方向垂直。例如，弹片14的主体方向(如图4中B所示)垂直于第二连料带12的延伸方向(如图4中A所示)。通过这种方式，弹片14的不同位置在垂直于延伸方向上的高度差更大，能有效地避免在对第一位置16进行镀化时，第一金属镀液影响其他位置。
此外，待镀化产品在延伸方向上的投影长度更小，这样相同长度的第二连料带12能设置更多的待镀化产品，这使得连续镀化的效率更高。
在一个例子中，预切料13包括位于待镀化产品沿延伸方向的两侧的连接部18。在冲压过程中，不同的连料单元15通过连接部18连接在一起，以便于加工。连续镀化方法还包括去除连接部18的至少局部，以露出第一位置16。如图3-4所示，不同的弹片14通过预切料固定到第二连料带12上时，连接部18会影响弹片14的第一位置16的镀化，浪费第一金属镀液。通过去除连接部18的至少局部，能保证第一位置16更好地浸入第一金属镀液中，并节约了镀液的用量。
在一个例子中，多个待镀化产品两两对称地设置在第二连料带12的两个工作面上。工作面即用于固定待镀化产品的表面。例如，如图6所示，第二连料带的沿长度、宽度上的前、后表面为工作面。两个连料单元15的预切料13被分别铆接在第二连料带12的前、后表面上。这样，通过一次铆接就能固定两个待镀化产品。并且能够同时对两个待镀化产品进行镀化，大大提高了连续镀化的效率。
优选地，如图6所示，两个待镀化产品之间的夹角呈锐角。这样，两 个待镀化产品的第一位置16相互间隔，能够有效避免在镀化过程中的相互干扰，保证了镀化质量。
虽然已经通过例子对本发明的一些特定实施例进行了详细说明，但是本领域的技术人员应该理解，以上例子仅是为了进行说明，而不是为了限制本发明的范围。本领域的技术人员应该理解，可在不脱离本发明的范围和精神的情况下，对以上实施例进行修改。本发明的范围由所附权利要求来限定。
