在焊接领域中，当工件焊接完成后，采用不同结构形式的折断组件来将辅料与工件相分离是众所周知的。在研究和实现辅料与工件相分离的过程中，发明人发现现有技术中的折断组件至少存在如下问题：
现有的折断组件大多采用夹持式结构，即将辅料上的折耳进行夹持后对辅料进行上下弯折来实现辅料与工件的分离，采用这种结构，由于焊接完毕后工件未冷却或者冷却不完全，极容易导致由于施加在折耳上的弯折力过大而导致焊点脱落、焊缝开裂、工件变形等问题，从而造成焊接次品率骤升。
有鉴于此，实有必要开发一种将辅料与工件相分离的折断组件，用以解决上述问题。

在下列描述中，诸如中心、厚度、高度、长度、前部、背部、后部、左边、右边、顶部、底部、上部、下部等用词是相对于各附图中所示的构造进行定义的，特别地，“高度”相当于从顶部到底部的尺寸，“宽度”相当于从左边到右边的尺寸，“深度”相当于从前到后的尺寸，它们是相对的概念，因此有可能会根据其所处不同位置、不同使用状态而进行相应地变化，所以，也不应当将这些或者其他的方位用于解释为限制性用语。
涉及附接、联接等的术语(例如，“连接”和“附接”)是指这些结构通过中间结构彼此直接或间接固定或附接的关系、以及可动或刚性附接或关系，除非以其他方式明确地说明。
根据本发明的一实施方式结合图1的示出可以看出，工件26包括工件本体261及与工件本体261相连的辅料262，所述辅料262上一体式地形成有 向上折起的折耳263，所述折耳263上开设有贯穿孔2631，所述工件本体261与辅料262的连接处形成有易折断的折痕264。在焊接过程中，焊接吸嘴可以通过吸取辅料262来实现对工件261(尤其是小尺寸工件)的稳定吸取及定位，本发明的主要目的是将辅料262从工件26上沿折痕264进行折断，以使得辅料262与工件本体261相分离，在分离过程中，并尽可能地减小对工件本体261造成的形变影响。
接下来参照图2～图5，可以看出，将辅料与工件相分离的折断组件25包括：
升降驱动器(图中未示出)；
折断安装板251，其与所述升降驱动器的动力输出端传动连接；
顶推驱动器253，其安装于所述折断安装板251上；
杆状的固定指252，其与所述折断安装板251相固接并且从所述折断安装板251出发向下悬垂；以及
杆状的滑动指254，其与所述顶推驱动器253的动力输出端传动连接并且从所述顶推驱动器253出发向下悬垂；
其中，所述折断安装板251在所述升降驱动器的驱动下在竖直平面内往复升降；所述固定指252的底部敞开形成有折断容纳腔255；所述滑动指254与所述固定指252相对设置，所述滑动指254上与所述固定指252相对的侧面固接有折断穿套杆2542；所述滑动指254在所述顶推驱动器253的驱动下靠近或远离所述固定指252以使得所述折断穿套杆2542插入所述折断容纳腔255中或者从所述折断容纳腔255中抽离。参照图5及图6，当工件26焊接完成后，将工件26放置于折断组件25的下方，使得折耳263与折断容纳腔255相对并位于折断容纳腔255的正下方，升降驱动器驱动折断安装板251下降，使得折耳263被所述折断容纳腔255所接收，并且至少部分贯穿孔2631没入所述折断容纳腔255中，随后顶推驱动器253驱动滑动指254靠近固定指，折断穿套杆2542进入折断容纳腔255后穿过贯穿孔2631使得折耳263穿套于折断穿套杆2542上，接着升降驱动器驱动折断安装板251在竖直平面内往复升降，参照图2，由于工件本体261被固定焊接于焊接基底上，辅料262只能以折痕264为边界线沿着箭头A及箭头B作围绕工件本体261的往 复弯折运动，最终使得辅料262与工件本体261相分离。采用上述特征所述的技术方案，通过将折耳263穿套于折断穿套杆2542上来使得在将折耳263折断过程中，折耳263通过沿着折断穿套杆2542往复滑移来减弱或消逝折断过程中产生的横向剪切力，从而防止由于施加在折耳263上的弯折力过大而导致焊点脱落、焊缝开裂、工件变形等问题，提高了焊接成品率，降低了生产成本。
再次参照图5或图6，所述折断容纳槽255大致呈倒置的U字形结构以在相对位置上形成：
远离所述固定指252的前侧壁2522；以及
与所述固定指252相对的后侧壁2521；
其中，所述滑动指254在所述顶推驱动器253的驱动下靠近或远离所述固定指252以使得所述折断穿套杆2542穿过所述后侧壁2521后插入所述折断容纳腔255中并至少部分地没入所述前侧壁2522中或者从所述折断容纳腔255中抽离。
进一步地，所述前侧壁2522与所述后侧壁2521从所述折断容纳槽255的顶部出发彼此平行或带一定张开角地至少近似沿着竖直方向延伸。采用这种结构能够防止折耳263在进入折断容纳槽255的过程中与前侧壁2522或后侧壁2521刮擦，从而提高折耳263进入折断容纳槽255的成功率，并防止折耳263在进入折断容纳槽255的过程中受到阻碍而变形。
参照图7及图8，所述后侧壁2521上开设有贯穿其前后的第一穿套孔2524，所述前侧壁2522上开设有贯穿其前后的第二穿套孔2525；当所述滑动指254在所述顶推驱动器253的驱动下靠近所述固定指252时，所述折断穿套杆2542依次穿过所述第一穿套孔2524、折断容纳槽255后至少部分没入所述第二穿套孔2525中。第二穿套孔2525的设置可以对折断穿套杆2542的前端形成封闭，以防止在折弯过程中折耳263从折断穿套杆2542的前端滑脱。
进一步地，所述第一穿套孔2524的孔径尺寸与所述折断穿套杆2542的径向尺寸相适配；所述第二穿套孔2525的孔径尺寸在竖直方向上大于所述折断穿套杆2542的径向尺寸，所述第二穿套孔2525的孔径尺寸在水平方向上 与所述折断穿套杆2542的径向尺寸相适配。采用这种结构，可以允许在折弯过程中，折断穿套杆2542收到折耳263的牵引后可以相对其在滑动杆254上的根部作小角度的转动，这有助于缓冲在折弯过程中折耳263收到的冲击力，进一步防止由于施加在折耳263上的弯折力过大而导致焊点脱落、焊缝开裂、工件变形等问题。
参照图4，定义所述第二穿套孔2525在竖直方向上的尺寸为H，定义折断穿套杆2542的径向尺寸为D，则有H:D＝1.1～2.5。在具体的实施过程中，H:D优选为2。
再次参照图6及图7，所述固定指252与所述滑动指254相对的侧面上开设有导向孔2523，所述滑动指254上固接有与所述导向孔2523相对的导向杆2541，所述导向孔2523的延伸方向与所述滑动指254的滑行方向相平行；当所述滑动指254在所述顶推驱动器253的驱动下靠近所述固定指252时，所述导向杆2541至少部分地插入所述导向孔2523之中。导向孔2523及与之对应的导向杆2541的设置可以使得所述滑动指254能够在所述顶推驱动器253的驱动下平稳地靠近所述固定指252，同时也有助于提高折断穿套杆2542穿入第二穿套孔2525的对接精度。
再次参照图6，所述滑动指254的前侧与所述固定指252的后侧相适配，所述滑动指254在所述顶推驱动器253的驱动下靠近所述固定指252直至所述滑动指254的前侧与所述固定指252的后侧相贴合。采用上述特征所述的技术方案，可以提高滑动指254与固定指252的配合紧密度，防止在弯折过程中由于滑动指254与固定指252发生错动而造成的折断失败。
应当理解的是，在本文中所使用的技术术语“折断失败”包括但不限于辅料262未能从工件本体261上折下，还包括虽然辅料262从工件本体261上折下但工件本体261也发生形如焊点松脱、焊缝开裂、工件变形、焊接基底受损等不可逆的破坏。
这里说明的设备数量和处理规模是用来简化本发明的说明的。对本发明的应用、修改和变化对本领域的技术人员来说是显而易见的。
尽管本发明的实施方案已公开如上，但其并不仅限于说明书和实施方式中所列运用，它完全可以被适用于各种适合本发明的领域，对于熟悉本领域 的人员而言，可容易地实现另外的修改，因此在不背离权利要求及等同范围所限定的一般概念下，本发明并不限于特定的细节和这里示出与描述的图例。
