在将定子绕组卷绕在齿（904）上时，需要将相邻分割铁芯（903）以连结部（906）为中心转动，使相邻分割铁芯（903）的相邻齿（904）远离，但是现有的电机定子铁芯（900）制作完成后，用于连接相邻分割铁芯（903）的连结部（906）连接牢固难以转动，现有的做法就是人工手动对连接部（906）进行松动，耗费大量人力的同时，作业效率低下。
 技术问题
本发明旨在克服上述现有技术的缺陷，提供一种电机定子铁芯的注油松动系统，能自动对电机定子铁芯进行松动，节省人力，提高作业效率。
 技术解决方案

 有益效果
与现有技术相比，本发明的有益效果为：本发明定位输送工装机构将定位安装于其上的电机定子铁芯输送至注油机构处，注油机构对电机定子铁芯的连接部加注润滑防锈油，移载机构将加注润滑防锈油后的电机定子铁芯移载至松动机构作业面，松动机构对电机定子铁芯的连接部进行松动，该注油松动系统能自动对电机定子铁芯进行松动，节省人力，提高作业效率，且移载机构移载过程中润滑防锈油慢慢渗透电机定子铁芯的连接部便于松动机构对其进行松动。

 本发明的实施方式
[0008] 如图1至图12所示，本实施例提供了一种电机定子铁芯的注油松动系统，包括控制单元及与控制单元连接的定位输送工装机构100、注油机构300、移载机构400及松动机构500；定位输送工装机构100用于定位安装并输送电机定子铁芯900，注油机构300用于对电机定子铁芯900的连接部906加注润滑防锈油，移载机构400用于移载电机定子铁芯900，松动机构500用于对加注润滑防锈油后的电机定子铁芯900的连接部906进行松动。
将电机定子铁芯900定位安装于定位输送工装机构100上，能保证电机定子铁芯900在周向上的开口角度，不但使得注油机构300能精准对需要松动的电机定子铁芯900的连接部906进行注油，而且使得松动机构500能从非连接的两个分割铁芯903处开始依次对连接部进行松动，保证松动机构500成功作业。
本实施例中，定位输送工装机构100将定位安装于其上的电机定子铁芯900输送至注油机构300处，注油机构300对电机定子铁芯900的连接部906加注润滑防锈油，移载机构400将加注润滑防锈油后的电机定子铁芯900移载至松动机构500作业面，松动机构500对电机定子铁芯900的连接部906进行松动，该注油松动系统能自动对电机定子铁芯900进行松动，节省人力，提高作业效率，且移载机构400移载过程中润滑防锈油慢慢渗透电机定子铁芯900的连接部906便于松动机构500对其进行松动。
其中，如图1所示，还包括与控制单元连接的相位检测机构200，用于检测安装于定位输送工装机构100上的电机定子铁芯900的角度。这样设置能确保电机定子铁芯900在定位输送工装机构100上的定位安装角度，保证电机定子铁芯900在周向上的开口角度。定位输送工装机构100将定位安装于其上的电机定子铁芯900输送至相位检测机构200，经过相位检测机构200的检测后，定位输送工装机构100将定位安装于其上的电机定子铁芯900输送至注油机构300处，由注油机构300加注润滑防锈油，使得润滑防锈油被精准注入电机定子铁芯900的连接部906。
另外，如图3所示，相位检测机构200包括第一驱动装置201及相位检测测定头204，第一驱动装置201与控制单元连接并用于驱动相位检测测定头204做升降运动；相位检测测定头204与电机定子铁芯900上的定位缺口901相匹配。第一驱动装置201驱动相位检测测定头204下降，相位检测测定头204插入电机定子铁芯900上的定位缺口901，则表示电机定子铁芯900在定位输送工装机构100上的定位安装角度正确，若相位检测测定头204无法插入电机定子铁芯900上的定位缺口901，则表示电机定子铁芯900在定位输送工装机构100上的定位安装角度错误，此时作业人员则需更正电机定子铁芯900在定位输送工装机构100上的定位安装角度才能保证该注油松动系统顺利工作；当相位检测机构200检测安装于定位输送工装机构100上的电机定子铁芯900的角度完毕后，第一驱动装置201驱动相位检测测定头204上升，定位输送工装机构100将电机定子铁芯900输送至注油机构300处。
本实施例中，如图3所示，所述相位检测机构200还包括圆周定位件203，圆周定位件203上设有插杆205，插杆205与电机定子铁芯900上相邻分割铁芯903的相邻齿904之间的缝隙902匹配；所述相位检测测定头204设于圆周定位件203上，第一驱动装置201用于驱动圆周定位件203做升降运动。插杆205与相邻齿904之间的缝隙902的匹配能对到达相位检测机构200位置处的电机定子铁芯900进行再次定位，确保相位检测测定头204能精准检测安装于定位输送工装机构100上的电机定子铁芯900的角度，避免误判。
其中，第一驱动装置201为气缸，相位检测机构200还包括用于引导相位检测测定头204升降方向的相位检测升降导向部件202。相位检测升降导向部件202可为导向杆加导向套的结构，导向杆在导向套内滑动实现导向。
本实施例中，所述注油松动系统还包括与控制单元连接的警报装置。当相位检测机构200检测到电机定子铁芯900在定位输送工装机构100上的安装角度错误时，控制单元控制警报装置发出警报，以提醒作业人员更正电机定子铁芯900在定位输送工装机构100上的安装角度。
另外，如图2所示，所述定位输送工装机构100包括输送板101及用于驱动输送板101运动的第二驱动装置104，第二驱动装置104与控制单元连接；输送板101上设有圆周定位工装部102，用于在圆周方向上定位并安装电机定子铁芯900；圆周定位工装部102上设有角度定位块103，用于定位电机定子铁芯900的角度；角度定位块103上设有定位凸起105，定位凸起105与电机定子铁芯900上分割铁芯903上的凹槽905相匹配。第二驱动装置104为传动链条结构，链条上设有用于安装输送板101的输送板安装部，输送板101与链条同步运动；圆周定位工装部102、角度定位块103及定位凸起105用于精确定位电机定子铁芯900在定位输送工装机构100上的安装位置；输送板101为多个以实现多工位作业，提高该注油松动系统的作业效率。
其中，如图4至图6所示，所述注油机构300包括第三驱动装置301、注油松紧动力机构303、注油夹爪304、注油缝隙板306及注油缝307；第三驱动装置301与控制单元连接并用于驱动注油松紧动力机构303做升降运动，注油松紧动力机构303与控制单元连接并用于驱动注油夹爪304做夹紧和松放运动，注油夹爪304用于夹紧和松放电机定子铁芯900的连接部906，注油缝隙板306设于注油夹爪304内，注油缝隙板306与注油夹爪304之间形成用于储放润滑防锈油的腔体，注油缝307设于注油缝隙板306上并用于向电机定子铁芯900的连接部906渗油。当电机定子铁芯900被输送至注油机构300处，第三驱动装置301驱动注油松紧动力机构303下降，注油松紧动力机构303驱动注油夹爪304夹紧电机定子铁芯900，润滑防锈油从注油缝307渗入电机定子铁芯900的连接部906，注油结束后，注油松紧动力机构303驱动注油夹爪304松放电机定子铁芯900，第三驱动装置301驱动注油松紧动力机构303上升；注油松紧动力机构303驱动注油夹爪304做夹紧和松放运动常见于工业上使用的机械手夹爪，为现有技术，不再详述。注油缝隙板306上设有用于向注油缝隙板306与注油夹爪304之间的腔体注油的孔，孔优选设在注油缝隙板306顶部。第三驱动装置301为气缸，所述注油机构300还包括用于引导注油夹爪304升降方向的注油升降导向部件302。注油升降导向部件302可为导向杆加导向套的结构，导向杆在导向套内滑动实现导向。
本实施例中，注油夹爪304和注油缝隙板306之间设有导油棉条305。这样设置使得润滑防锈油经过导油棉条305后从注油缝307中均匀渗出，进而均匀渗入电机定子铁芯900的连接部906，便于松动机构500对电机定子铁芯900的连接部906进行松动。
另外，如图7至图8所示，所述移载机构400包括第四驱动装置401及移载夹爪装置402，第四驱动装置401与控制单元连接并用于驱动移载夹爪装置402做平面直线运动；所述移载夹爪装置402包括移载升降驱动装置405、移载夹紧松放动力机构406及移载夹爪407，移载升降驱动装置405与控制单元连接并用于驱动移载夹紧松放动力机构406做升降运动，移载夹紧松放动力机构406与控制单元连接并用于驱动移载夹爪407做夹紧和松放运动，移载夹爪407用于夹紧和松放电机定子铁芯900。当需要移载电机定子铁芯900时，第四驱动装置401驱动移载夹爪装置402做平面直线运动至电机定子铁芯900正上方，移载升降驱动装置405驱动移载夹紧松放动力机构406下降，移载夹紧松放动力机构406驱动移载夹爪407做夹紧动作以将电机定子铁芯900紧紧夹住，移载升降驱动装置405驱动移载夹紧松放动力机构406上升，第四驱动装置401再次驱动移载夹爪装置402做平面直线运动直至电机定子铁芯900到达目标位置正上方，移载升降驱动装置405驱动移载夹紧松放动力机构406下降，移载夹紧松放动力机构406驱动移载夹爪407做松放动作以将电机定子铁芯900松开。移载夹爪装置402为两个，第四驱动装置401驱动一个移载夹爪装置402做平面直线运动，以将待松动的电机定子铁芯900从定位输送工装机构100上移载至松动机构500作业面，第四驱动装置401驱动另一个移载夹爪装置402做平面直线运动，以将松动完成的电机定子铁芯900从松动机构500作业面移载至出料装置600上，出料装置600为带轮带动皮带传输以完成自动出料，为现有技术，在此不再详述。第四驱动装置401为电机；移载升降驱动装置405为气缸，所述移载夹爪装置402还包括用于引导移载夹爪407升降方向的移载升降导向部件404。移载升降导向部件404可为导向杆加导向套的结构，导向杆在导向套内滑动实现导向。移载夹紧松放动力机构406驱动移载夹爪407做夹紧和松放运动常见于工业上使用的机械手夹爪，为现有技术，不再详述。
本实施例中，移载夹爪407与电机定子铁芯900的接触面设有软胶结构。这样设置能防止夹伤电机定子铁芯900。
其中，如图9至图12所示，所述松动机构500包括松动牵引板511、松动驱动装置及松动治具510，松动驱动装置与控制单元连接并用于驱动松动牵引板511在X-Y平面移动，松动牵引板511与松动治具510转动连接；松动治具510包括松动治具底座519、松动治具定位固定块515、松动治具活动块512和松动治具关节轴513，松动治具活动块512上设有分割铁芯固定机构；松动治具活动块512、分割铁芯固定机构和电机定子铁芯900中的分割铁芯903数量相同，分割铁芯固定机构用于将电机定子铁芯900中的一个分割铁芯903固定在对应的松动治具活动块512上；相邻松动治具活动块512通过松动治具关节轴513转动连接，松动治具定位固定块515用于将一个松动治具活动块512定位安装于松动治具底座519上；其中两个相邻松动治具活动块512为非连接，且松动牵引板511与非连接的两个相邻松动治具活动块512中的一个转动连接。松动牵引板511和松动驱动装置可为对称设置的两套，两松动牵引板511分别与非连接的两个相邻松动治具活动块512转动连接；这样可提高松动作业效率。当松动驱动装置驱动松动牵引板511在X-Y平面移动时，松动牵引板511移动并带动松动治具活动块512转动，松动治具活动块512转动带动对应的分割铁芯903绕松动治具关节轴513转动，以完成松动作业。松动治具定位固定块515为两块，分别设于其所在的松动治具活动块512的外内两侧，且位于外侧的松动治具定位固定块515尺寸大于位于内侧的松动治具定位固定块515，以增加其所在的松动治具活动块512在松动治具底座519上安装的牢固性；位于外侧的松动治具定位固定块515在与电机定子铁芯900接触的表面设有松动治具定位凸块，所述松动治具定位凸块与一个分割铁芯903上的凹槽905相匹配，以将该分割铁芯903牢固地固定在该松动治具定位凸块上，进而便于松动机构作业。松动治具定位固定块515用于将一个松动治具活动块512定位安装于松动治具底座519上，一般是将位于中间位置处的松动治具活动块512定位安装于松动治具底座519上，这样正好对应中间位置处的分割铁芯903，便于两边同时开始松动作业。
另外，分割铁芯固定机构包括分别设于松动治具活动块512外内两侧的松动治具活动外爪514和松动治具活动内爪517。松动治具活动外爪514、松动治具活动内爪517和对应的松动治具活动块512配套以将一个分割铁芯903固定在该松动治具活动块512上，当该松动治具活动块512绕松动治具关节轴513转动时，则带动对应的分割铁芯903绕相邻分割铁芯903之间的连结部906转动，以完成松动作业。
