Description

转接焊焊头装置 技术领域
本发明涉及焊接技术领域，特别是涉及一种转接焊焊头装置。
背景技术
在焊接焊件如复合集流体时，由于复合集流体耐热性低，所以传统技术中采用转接焊的方式，即在复合集流体之间加一层传统箔材，传统箔材用作转接体。转接焊通过超声焊接装置在高频振动下使相邻宿片的原子振动，从而使复合集流体与转接体焊接在一起。为了增加焊头和材料之间的摩擦力，保证焊头能够带动被焊接材料作高频振动，焊头压紧材料的工作面上有多个焊齿，如球齿和圆锥齿等。
传统的转接焊方法存在以下不足：一是焊接过程中有粘接焊头的现象，易产生金属屑，导致内部短路，影响电池安全性能；二是焊接头焊齿形状存在问题，如球齿四周比较平滑，容易出现打滑的现象，而圆锥齿虽比较容易刺入焊件如复合集流体，但容易让焊件表层出现穿孔现象，导致焊接质量不佳；三是转接焊操作流程相对复杂，影响焊接效率。
发明内容
基于此，针对传统的转接焊存在的易产生金属屑、粘接焊头的现象，焊接头焊齿容易出现打滑、易刺入焊件的现象，转接焊操作流程相对复杂，影响焊接效率的问题，本发明一实施例提供一种转接焊焊头装置。本发明的转接焊焊头装置能够有效解决焊接过程中粘接焊头的现象，同时提升转接体和复合集流 体之间的焊接结合力与焊接效率。
一种转接焊焊头装置，包括：

本申请实施例提供一种转接焊焊头装置10，以解决传统的转接焊存在的易产生金属屑、粘接焊头的现象，焊接头焊齿容易出现打滑、易刺入焊件的现象，转接焊操作流程相对复杂，影响焊接效率的问题。以下将结合附图对进行说明。
本申请实施例提供的转接焊焊头装置10，示例性的，请参阅图1所示，图1为本申请实施例提供的转接焊焊头装置10的结构示意图。本申请的转接焊焊头装置10能够用于复合集流体20焊接。
为了更清楚的说明转接焊焊头装置10的结构，以下将结合附图对转接焊焊头装置10进行介绍。
示例性的，请参阅图1所示，图1为本申请实施例提供的转接焊焊头装置10的结构示意图。一种转接焊焊头装置10包括第一焊接机构100以及第二焊接机构200。
第一焊接机构100包括第一焊头主体101、第一焊齿基台底座102以及第一焊齿组件103。第一焊头主体101上设置有若干个第一焊齿基台底座102。部分第一焊齿基台底座102上连接有第一焊齿组件103。第一焊齿组件103包括若干个第一焊齿头1031。
第二焊接机构200包括第二焊头主体201、第二焊齿基台底座202以及第二焊齿组件203。第二焊头主体201上设置有若干个第二焊齿基台底座202。部分第二焊齿基台底座202上连接有第二焊齿组件203。第二焊齿组件203包括若干个第二焊齿头2031。
在使用状态时，第二焊头主体201与第一焊头主体101相对设置，且第二焊齿基台底座202上的多个第二焊齿组件203与第一焊齿基台底座102上的多个第一焊齿组件103错位分布。错位分布后，当第二焊头主体201与第一焊头 主体101贴合时，具有第二焊齿组件203的第二焊齿基台底座202与空缺第一焊齿组件103的第一焊齿基台底座102配合，空缺第二焊齿组件203的第二焊齿基台底座202与具有第一焊齿组件103的第一焊齿基台底座102配合，如此，能够保证第二焊头主体201与第一焊头主体101配合加工复合集流体20时，每一组第一焊齿基台底座102与相对的第二焊齿基台底座202之间均有第二焊齿组件203或者第一焊齿组件103，错位分布的设计不仅可以避免因超声共振可能导致的焊齿头损坏，还可以在互相咬合的作用下提高焊接强度。另外，第一焊齿基台底座102与相对的第二焊齿基台底座202上下焊头不仅起到超声焊接的作用，还可以相互互为支撑。
上述转接焊焊头装置10能够有效解决焊接过程中粘接焊头的现象，同时提升转接体21和复合集流体20之间的焊接结合力与焊接效率。上述转接焊焊头装置10在使用时，在复合集流体20的两侧分别加一层传统箔材用作转接体21，转接焊通过超声焊接装置，在高频振动下使相邻宿片的原子振动，从而使复合集流体20与转接体21金属薄焊接在一起，即焊接过程采用第一焊头主体101和第二焊头主体201同步焊接的方式，提高焊接效率，避免了传统技术中底模的使用，取消了传统技术中底模需要定位准确、牢固稳定安装的步骤，进一步地提高焊接效率。
在其中一些实施例中，第一焊头主体101用于与第二焊头主体201相配合的一侧具有第一焊接配合面。第一焊接配合面上设置有若干个第一焊齿基台底座102。
在其中一些实施例中，第二焊头主体201用于与第一焊头主体101相配合的一侧具有第二焊接配合面。第二焊接配合面上设置有若干个第二焊齿基台底座202。在加工时，第一焊接配合面与第二焊接配合面相互平行设置。
在其中一些实施例中，多个第一焊齿头1031在第一焊齿基台底座102上呈矩阵分布。例如，在一个具体示例中，参见图6所示，多个第一焊齿头1031在第一焊齿基台底座102上呈三行三列分布。不难理解，在其他具体示例中，多个第一焊齿头1031在第一焊齿基台底座102上还可以呈矩阵分布的行数与列数不相等。
在其中一些实施例中，多个第二焊齿头2031在第二焊齿基台底座202上呈矩阵分布。例如，在一个具体示例中，参见图6所示，多个第二焊齿头2031在第二焊齿基台底座202上呈三行三列分布。不难理解，在其他具体示例中，多个第二焊齿头2031在第二焊齿基台底座202上还可以呈矩阵分布的行数与列数不相等。
在其中一些实施例中，第一焊齿头1031上具有防粘涂层。防粘涂层有效解决焊接过程中粘接焊头的现象，同时还提升转接体21和复合集流体20之间的焊接结合力与焊接效率。
在其中一些实施例中，第二焊齿头2031上具有防粘涂层。防粘涂层有效解决焊接过程中粘接焊头的现象，同时还提升转接体21和复合集流体20之间的焊接结合力与焊接效率。
在其中一些实施例中，防粘涂层的材料为Al-Cu-Fe准晶涂层。
在其中一些实施例中，防粘涂层的厚度为5μm～30μm。例如，在一个具体示例中，防粘涂层的厚度为5μm。在另一个具体示例中，防粘涂层的厚度为30μm。不难理解，在其他示例中，防粘涂层的厚度还可以是6μm、8μm、9μm、10μm、12μm、15μm、16μm、18μm、19μm、20μm、22μm、25μm、26μm、28μm、29μm或者其他参数。
在其中一些实施例中，防粘涂层采用物理热喷涂、气相沉积或离子镀方法 制备形成。
在其中一些实施例中，第一焊齿基台底座102相对于第一焊头主体101的高度≥第一焊齿头1031相对于第一焊齿基台底座102的高度。
在其中一些实施例中，第二焊齿基台底座202相对于第二焊头主体201的高度≥第二焊齿头2031相对于第二焊齿基台底座202的高度。
在其中一些实施例中，多个第一焊齿基台底座102在第一焊头主体101上呈矩阵分布。在一个具体示例中，参见图2及图3所示，多个第一焊齿基台底座102在第一焊头主体101上呈三行七列分布，此时，每一行上的七个第一焊齿基台底座102间隔分布有第一焊齿头1031。优选地，参见图3所示，第一行上的第二、四、六列位置的第一焊齿基台底座102上分布有第一焊齿头1031，第二行上的第一、三、五、七列位置的第一焊齿基台底座102上分布有第一焊齿头1031，第三行上的第二、四、六列位置的第一焊齿基台底座102上分布有第一焊齿头1031。
在其中一些实施例中，多个第二焊齿基台底座202在第二焊头主体201上呈矩阵分布。在一个具体示例中，参见图4及图5所示，多个第二焊齿基台底座202在第二焊头主体201上呈三行七列分布。优选地，参见图5所示，第一行上的第一、三、五、七列位置的第二焊齿基台底座202上分布有第二焊齿头2031，第二行上的第二、四、六列位置的第二焊齿基台底座202上分布有第二焊齿头2031，第三行上的第一、三、五、七列位置的第二焊齿基台底座202上分布有第二焊齿头2031。
在其中一些实施例中，第一焊齿基台底座102呈多棱台体、圆台体、半圆球体以及弧形体中的一种或几种。

例如，在一个具体示例中，第一焊齿基台底座102呈四棱台体，第一焊齿基台底座102上的多个第一焊齿头1031呈半球体，第一焊齿基台底座102上的多个第一焊齿头1031呈三行三列等间隔分布。参见图7所示，第一焊齿基台底座102的高度h1≥第一焊齿头1031的直径R1，第一焊齿基台底座102的侧面与底面的夹角α1呈45°～75°。参见图6所示，每一行上的相邻的第一焊齿头1031之间的间距d1等于每一列上的相邻的第一焊齿头1031之间的间距d1，其中d1＜R1。R1＜第一焊齿基台底座102的顶面边长L1。进一步地，R1＜1/2L1。对应地，第二焊齿基台底座202呈四棱台体，第二焊齿基台底座202上的多个第二焊齿头2031呈半球体，第二焊齿基台底座202上的多个第二焊齿头2031呈三行三列等间隔分布。第二焊齿头2031的直径R2＝R1，第二焊齿基台底座202的高度h2＝h1，第二焊齿基台底座202的侧面与底面的夹角α2＝α1。每一行上的相邻的第二焊齿头2031之间的间距d2＝d1。第二焊齿基台底座202的顶面边长L2＝L1。也即是说，第二焊头主体201与第一焊头主体101的形状、尺寸基本相同，区别在于第二焊齿基台底座202上的多个第二焊齿组件203与第一焊齿基台底座102上的多个第一焊齿组件103错位分布。
例如，在一个具体示例中，第一焊齿基台底座102呈三棱台体、半球体或弧形体时，第一焊齿头1031在第一焊齿基台底座102上垂直正投影的圆形直径小于1/2倍的第一焊齿基台底座102在第一焊头主体101上垂直正投影面的对称 轴线值。对应地，第二焊头主体201与第一焊头主体101的形状、尺寸基本相同，区别在于第二焊齿基台底座202上的多个第二焊齿组件203与第一焊齿基台底座102上的多个第一焊齿组件103错位分布。
在其中一些实施例中，转接焊焊头装置10还包括驱动机构。驱动机构连接于第一焊头主体101和/或第二焊头主体201。驱动机构用于驱动第一焊头主体101与第二焊头主体201相互靠拢或者分离。优选地，驱动机构连接于位于上方的第一焊头主体101，第二焊头主体201固定，驱动机构驱动第一焊头主体101运动，以实现向第二焊头主体201靠拢或者分离。

焊接时，焊接能量为38J，焊接振幅28μm，焊接压力20PSI。驱动机构驱动第一焊头主体101运动以实现向第二焊头主体201靠拢完成复合铜集流体转接焊，焊接过程无粘接现象。本实施例焊接后的产品测试最大T型剥离载荷为260N。相比传统焊接机相同焊接条件下对比样品最大T型剥离载荷为200N，表面本发明的转接焊焊头装置10能够有效提升复合集流体20焊接粘结力，提高焊接效率。
