具体实施方式
以下将结合实施例和附图对本发明的构思、具体结构及产生的技术效果进行清楚、完整的描述，以充分地理解本发明的目的、方案和效果。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。
需要说明的是，如无特殊说明，当某一特征被称为“固定”、“连接”在另一个特征， 它可以直接固定、连接在另一个特征上，也可以间接地固定、连接在另一个特征上。此外，本发明中所使用的上、下、左、右等描述仅仅是相对于附图中本发明各组成部分的相互位置关系来说的。
此外，除非另有定义，本文所使用的所有的技术和科学术语与本技术领域的技术人员通常理解的含义相同。本文说明书中所使用的术语只是为了描述具体的实施例，而不是为了限制本发明。本文所使用的术语“及/或”包括一个或多个相关的所列项目的任意的组合。
图1是本发明一个实施例的组成结构示意图，参照图1-图11，该变压器引线焊接设备包括：
工作台1，焊接模组2，焊接治具3，供线模组4，压锡尖模组5，三轴机械手6，扯线模组7以及机架8。
本发明中，机架8承载工作台1以及若干焊接模组2，若干焊接模组2沿工作台1的周向均匀分布，单个焊接模组2包括电烙铁20，电烙铁20与第一联动组件21的端部连接，电烙铁20在第一联动组件21的作用下，相较于工作台1可做水平和竖直位移，且电烙铁20朝向工作台1设置；工作台1上设置有若干组用于固定变压器的焊接治具3，且工作台1绕中心轴转动，如此，工作台1在旋转时带动焊接治具3上固定的变压器旋转，使若干组焊接治具3上的变压器转动至若干个焊接模组2处，同时被若干个焊接模组2中的电烙铁20焊接铜箔和引脚处的引线，取代传统的手工焊接引线的方式，整个焊接设备的自动化程度高，焊接效率显著提升，焊接质量稳定。
此处，第一联动组件21可以视需求与成本设置为两轴机械手或者三轴机械手。
本实施例中，优选地，电烙铁20包括铜箔焊接电烙铁201与引脚焊接电烙铁202，铜箔焊接电烙铁201焊接铜箔处的引线，引脚焊接电烙铁202焊接引脚处的引线。铜箔焊接电烙铁201与引脚焊接电烙铁202的规格型号不同。设置不同规格型号的电烙铁，用于焊接变压器的不同部位，既可以保证焊接质量，又可以提高焊接效率。
进一步，优选地，焊接模组2包括的是柔性焊接装置。
该柔性焊接装置包括有弹性滑动机构26和电烙铁组件27。
图3是该柔性焊接装置的弹性滑动机构的一个实施例的爆炸图，其中，弹性滑动机构26包括安装板261，电烙铁组件27安装在安装板261上，安装板261固定在滑动块262上，滑动块262固定在T形块263上，T形块263嵌合在U形基座264上，T形块263上设置有限位板265，限位板265限制T形块263的移动位置，T形块263的上方设置有压板266，压板266和T形块263之间设置有弹簧267，压板267固定在U形基座264上。优选地，T形块263上设置有第一凹槽2631，压板266上的对应位置也设置有第二凹槽(图中未示出)，第一凹槽2631和第二凹槽之间放置弹簧267，优选地，第一凹槽2631、第二凹槽和弹簧267的数量均为两个。优选地，安装板261通过腰形孔2611、螺钉紧固件(图中未示出)与滑动板262连接，即安装板261相对滑动板262的位置可调，即固定于安装板261上的电烙铁组件27相对于弹性滑动机构26的位置可调。
图2是焊接模组的一个实施例的组成结构示意图，图4是该柔性焊接装置的一个实施例的轴测图，其中，电烙铁组件27通过第一万向球270安装在弹性滑动机构26的安装板261上；电烙铁组件27包括电烙铁20、V形架271、送锡管272、定位块273以及第二万向球274，V形架271包括有第一臂2710和第二臂2711，第一臂2710固定在电烙铁20上，第二臂2711通过第二万向球274固定送锡管272，送锡管272可 输送焊锡；第二臂2711抵接在定位块273上。优选地，第一臂2710上设置有若干通孔，第二臂2711上也设置有若干通孔，第一臂2710和第二臂2711锁接，此时第一臂2710和第二臂2711之间的角度可调，第二臂2711相对第一臂2710的长度可调，由此有利于第二臂2711上连接的送锡管272的位置调节。
优选地，电烙铁20包括有烙铁柄203和烙铁头204，烙铁头204上固定有锁接块205，烙铁头204通过锁接块205与烙铁柄203锁接，锁接块205上固定有隔热块206。进一步地，隔热块206的四周呈多边形。当烙铁头204需要更换时，转动V形架271的第二臂2711，从而将第二臂2711上固定的送锡管272移开，利用固定在烙铁头204上的隔热块206，使用手工或者扳手等工具进行烙铁头204的快速拆卸，而不需要等待烙铁头204自然冷却，避免自动化进程的停顿时间过长。烙铁头204更换后，由于第一臂2710上固定有定位块273，将第二臂2711停靠在定位块273后锁紧固定，送锡管272继续送锡。
之所以设置以上柔性焊接装置，是因为铜箔的表面不是标准的平面，一般都是呈弧面，且各个铜箔的表面的弧度并不完全一致，因此需要电烙铁在焊接时能随时适应铜箔的表面弧度，防止虚焊、焊接不牢固等问题的产生，进一步提高铜箔处的焊接质量。
此处，弹性滑动机构26安装完成后，弹簧267处于压缩状态，T形块263及其上面间接固定连接的电烙铁组件27具有一个向下的预紧力，由此电烙铁20可适应变化不定的产品表面，防止虚焊、焊接不牢固等不良现象的产生。
本实施例中，优选地，本发明还包括供线模组4，供线模组4用于向焊接模组2提供引线，此处供线模组4的结构以及具体实施例参照2017.07.28提交的发明专利申请号为201710633056.4，名称为“一种铜箔线圈电焊机”的发明专利申请中的送线模组。申请人已在上述发明专利申请文件中将送线模组公开为现有技术。
此处，供线模组4安装在一个三轴机械手上，通过三轴机械手的位移，安装于三轴机械手上的供线模组4实现将引线从铜箔焊接处走线至引脚焊接处，并在引脚处实现将部分引线缠绕到引脚上的动作。进一步地，可以将第一联动组件21优选为三轴机械手，供线模组4与电烙铁20共用一个三轴机械手，在实现功能的基础上，简化设备结构，节约设备成本。
本实施例中，优选地，焊接模组2还包括松香料盘23，松香料盘23与第二联动组件24的端部连接，并在第二联动组件24的作用下相对电烙铁20做水平以及竖直方向的位置。电烙铁20工作一段时间后，与松香料盘23分别在第一联动组件21、第二联动组件24的作用下实现相对运动，将电烙铁20与松香料盘23中的松香接触，松香作为助焊剂可以提高焊接质量。此处，第二联动组件24可以视需求与成本设定为两轴机械手或者三轴机械手。
图5为本发明中焊接治具的一个实施例的组成结构示意图。
本实施例中，优选地，如图5所示，每组焊接治具3包括若干夹持机构30、若干第一驱动机构31以及固定板32，夹持机构30在第一驱动机构31的作用下松开与夹紧变压器，第一驱动机构通过固定板32固定安装在工作台1上。此处，工作台1上的每组焊接治具3包括若干组用于松开与夹紧变压器的夹持机构30以及第一驱动机构31，可以增加每组焊接治具3固定的变压器的数量，进一步提高焊接效率。
此处，第一驱动机构31优选为滚柱型气动手指，夹持机构30与所述滚柱型气动手指的前端固定连接，滚柱型气动手指具有高强度、高精度、高载荷，调节时方便灵活的优点。
夹持机构30优选为两爪结构，两爪结构中的两根爪的距离由上述滚柱型气动手指调节，实现松开与夹紧变压器，完成变压器相对焊接治具3的上下料，结构简单、动作准确。
如图6所示，本实施例中，优选地，第一驱动机构31与固定板32之间设置有回转机构33，回转机构33通过第一驱动机构31带动夹持机构30回转，进而带动夹持机构30夹持的变压器回转。通过转动变压器，使变压器上的引脚变换位置，例如变压器上的引脚分为上下两排，当电烙铁20对变压器的上排引脚焊接完成后，通过回转机构33翻转变压器，使变压器已经焊好的上排引脚转到下方，未焊接的下排引脚转到上方，方便电烙铁20焊接。
在未设置回转机构33时，为焊接变压器的下排引脚，对变压器下料、进行翻转后再重新上料，或者电烙铁20在有限的空间内避让开已经焊接好的上排引脚，找正下排引脚进行焊接，且焊接过程中，要保证灼热的电烙铁20不会对进行焊接好的上排引脚造成影响。以上方式效率低且不易实行，回转机构33的增设可以快捷灵活地通过旋转变压器改变变压器上引脚的位置，操作简单，效率高，并且能够保证引脚的焊接质量。
此处，回转机构33优选为回转气缸，结构简单有效。
图7为本发明中的引线规整机构的一个实施例的组成结构示意图。
本实施例中，优选地，如图2、图7所示，焊接模组2还包括引线规整机构25，引线在从铜箔焊接处走线至引脚焊接处的过程中，引线浮于变压器的表面，引线规整机构25对浮于变压器表面的引线进行按压与规整，使其与变压器的表面贴合，避免引线在变压器的表面悬空，从而发生断裂，影响变压器的产品质量。
进一步地，引线规整机构25包括支架251、气缸滑台252以及规整头253，支架251固定安装在工作台1上，气缸滑台252的一端与支架251固定连接，另一端与规整头253固定连接，规整头253朝向由焊接治具3固定的变压器设置，并且规整头253在气缸滑台252的作用下相对变压器位移，以调节规整头253与变压器之间的相对位置；规整头253的端部的形状与待按压的引线所对应的变压器的表面的形状相互配合，如此，规整头253在按压过程中既不会刮伤、挤伤变压器的表面，还能通过按压使铜箔焊接处与引脚焊接处之间的引线紧贴变压器的表面。有时，进一步地，还会在铜箔焊接处与引脚焊接处之间的引线所对应的变压器的表面开设安置引线的凹槽，进一步避免了引线浮于变压器的表面发生断裂，此时，规整头253形状与上述凹槽适配即可。
本实施例中，优选地，工作台1分为上、下两层，焊接治具3固定安装于工作台1的下层，引线规整机构25固定安装于工作台1的上层；引线规整机构25与焊接治具3一一对应，即一组焊接治具3上的若干个变压器的引线规整工作由一个引线规整机构25完成。将工作台1分为上、下两层，可以减省工作台1的单层的面积，进而减小设备的占地面积；优选地，将支架251与工作台1的上层之间的固定连接结构设置为腰形孔与锁紧螺栓，通过调节锁紧螺栓在腰形孔中的位置，可以对规整机构25与焊接治具3上的变压器之间的相对位置进行微调。
本实施例中，优选地，还包括压锡尖模组5，因电烙铁20在焊接铜箔处的焊锡有可能形成尖锐的锡尖，既不美观也不安全，因此，压锡尖模组5对形成的锡尖进行压合规整，将其去除，以优化焊接质量。
此处，压锡尖模组5包括柔性压锡尖装置，能有效去除锡尖且不破坏变压器的结构，适用于自动化进程，除锡尖效率高。
图8是柔性压锡尖装置的一个实施例的轴测图，其中，柔性压锡尖装置包括框架50，框架50上安装有压锡尖组件51和顶板组件52，其中，压锡尖组件51在框架50的上方，顶板组件52在框架50的下方，且顶板组件52与压锡尖组件51位置对应。
图9是压锡尖组件51的一个实施例的爆炸图。如图8、图9所示，压锡尖组件51包括压锡尖安装板510和压锡尖单元511，压锡尖单元511包括按压块5110和弹性元件5120，弹性元件5120两端分别抵持在压锡尖安装板510和按压块5110上；顶板组件52包括顶板520和第一驱动单元521，第一驱动单元521可驱动顶板520朝按压块5110运动，实现压锡尖的动作。此处，弹性元件5120优选为压缩弹簧，压缩弹簧套在定位销5130上，压缩弹簧一端抵接在定位销5130的凸缘上，定位销5130的凸缘抵接在按压块5110的阶梯孔中，压缩弹簧另一端抵接在压锡尖安装板510上，由此按压块5110保持有向下的弹性预紧力。
此处，优选地，压锡尖安装板510上安装有第二驱动单元512，第二驱动单元512可驱动压锡尖安装板510在前后方向上运动，此处，第二驱动单元512为滑台气缸，压锡尖安装板510另一端设置有线性导轨513进行运动的协调稳定，当然线性导轨513也可为线性导向轴与滑块的组合、燕尾型导轨等公知的滑动部件进行代替。进一步地，包括定位治具54，定位治具54上放置若干个变压器。进一步地，框架50上还设置有输送带53，输送带53可用一些较公知的技术手段进行驱动，例如利用电机经减速机减速后将运动传递给输送带53，输送带53上放置有定位治具54，定位治具54可随输送带53一起运动。
顶板520通过第一驱动单元521进行上下运动，在本实施例中，第一驱动单元521为气缸，第一驱动单元521固定在顶板基板530上，顶板基板530与框架50固定，顶板520上还固定有尖头540，尖头540设置在顶板520两端，定位治具54设置有相配合的孔，在本实施例中，孔为设置于一端的圆孔和设置于另一端的腰形孔，由此可增加顶压动作的容错率。
优选地，框架50下方还安装有限位组件55，限位组件55包括有限位头551和第三驱动单元552，第三驱动单元552可为气缸，限位头551在第三驱动单元552的驱动下可拦住定位治具54，此时顶板组件52可将放置有变压器的定位治具54推向压锡尖组件51，压锡尖动作完成后，顶板组件52下放，定位治具54回落在输送带53上，限位组件55放开限制，定位治具54带着变压器向下道工序流去。
优选地，压锡尖安装板510还设置有吹气管5101，吹气管5101对准按压块5110的按压部，吹气管5101连接气源后可将锡尖渣吹开，吹气管5101可设置多个，在本实施例中，多个吹气管5101固定在吹气管安装板5102上，吹气管安装板5102固定在压锡尖安装板510上。
图10是本发明中的三轴机械手的一个实施例的组成结构示意图。
本实施例中，优选地，如图10所示，本发明还包括三轴机械手6，变压器经焊接模组2的焊接，在工作台1的转动与三轴机械手6的位移配合下、由三轴机械手6抓取并放置到压锡尖模组5的定位治具54上。
此处，三轴机械手6还包括拖链结构61，用于对三轴机械手6中的线路以及管道进行规整约束，起到牵引与保护作用，使结构整洁。
图11是本发明中的扯线模组的一个实施例的组成结构示意图。
本实施例中，优选地，如图11所示，还包括扯线模组7，扯线模组7包括第三联动组件71、位移气缸72以及连接板73，其中，位移气缸72与第三联动组件71 固定连接，并在第三联动组件71的作用下，竖直或者在水平面内做靠近或远离定位治具54的位移。连接板73与位移气缸72滑动连接，所以，连接板74在第三联动组件71以及位移气缸72的作用下实现多向位移，同时连接板73上设置有若干气动夹爪74，气动夹爪74夹住变压器的引脚处的多余的引线，在气动夹爪74随连接板多向位移的过程中，变压器的引脚处的多余的引线被弯折绕动，进而扯断。此处，扯线模组7将变压器的引脚处的多余的引线扯断，且弯折绕动的位移方式模拟人手扯线的动作，不会使引线在扯断时的断裂面凹凸不平，进一步提升了焊接以后的产品的质量。此处，第三联动组件71为两轴或者三轴联动件。
进一步地，气动夹爪74在与连接板73的连接处设置有起缓冲作用的弹簧75，使扯线动作更加柔和，优化扯线的质量。气动夹爪74将扯下的引线丢进下方的废料收集箱76。
以上是对本发明的较佳实施进行了具体说明，但本发明创造并不限于所述实施例，熟悉本领域的技术人员在不违背本发明精神的前提下还可做出种种的等同变形或替换，这些等同的变形或替换均包含在本申请权利要求所限定的范围内。
