金属料带在生产设备的上模组件和下模组件之间，金属料带以连续步进式向落料方向输送，使铁芯片预成型区贴合于生产设备中的粘胶喷涂装置上，第一喷胶控制装置中的胶筒内粘胶通过粘胶控制设备输送至粘胶喷涂装置的第一喷胶口处，第二喷胶控制装置中的胶筒内粘胶通过粘胶控制设备输送至粘胶喷涂装置的第二喷胶口处，并使第一喷胶口和第二喷胶口所喷出的粘胶粘附在铁芯片预成型区的下表面，并在铁芯片预成型区的下表面均匀分布有胶点；
金属料带在连续步进式输送过程中，对金属料带上涂覆有粘胶的铁芯片预成型区作冲裁处理，以成型铁芯片，并落料至落料通道内与其内部的铁芯片叠片组顶面之间通过粘胶与混合液体接触而固化粘接，以形成层叠铁芯；固化粘接时，在15℃-35℃的温度环境中经过10s-3min的时间完成粘接，以及所成型的铁芯片受上模组件的成型模施压，铁芯片叠片组受液压缸的背压力和锁紧圈的包紧力作用下，以使所成型的铁芯片与铁芯片叠片组顶面之间紧密地常温固化快速粘接。
根据以上所述的电机层叠铁芯的生产方法，金属料带连续步进式向落料方向输送的方式采用前推后拉的方式。

与现有技术相比，本发明所设计的电机层叠铁芯的生产设备及其生产方法，有益效果如下：
1、多个第一喷胶口通过第一模板上的第一分流通道与第一进胶通道连通，以及多个第二喷胶口通过第二模板上的第二分流通道与第二进胶通道连通的结构设置，使得仅需两根管道分别与第一进胶通道和第三进胶通道对接即可实现粘胶输入至第一喷胶口和第二喷胶口，解 决了现有技术中需要每个喷胶口进行连接管道的管道连接数量较多，导致管道对接安装较为麻烦，管道安装效率低下，同时不利于检修的技术问题，进一步达到了管道与喷胶口安装快捷，由于管道数量较少，可快速的找到对应出现故障的管道，提升检修速度，并且清洗方便，也无需经常性更换易损零件，后期保养方便。
2、对于分流腔的设置，使得粘胶在分流腔内汇集后再分流，使得喷胶口在喷胶时提供一定的压力，并且使得每个喷胶口所喷出的粘胶的压力均衡，以对喷出的胶量得到控制。
3、对于连通槽的设置使得一分流通道中的粘胶出现过多时可满溢至其它分流通道，使得每个分流通道中的粘胶量均衡，促使每个喷胶所喷出的粘胶量均匀，使得在铁芯片上涂覆的胶点厚度一致，促使粘接成型的每个电机铁芯厚度也一致，提升成品率。
4、在金属料带的侧边设置用于引导料带的侧导板，以对步进式输送的金属料带进行定位，并且在侧导板上设置磁铁，以使得金属料带可与下模组件分离，而且分离后金属料带被磁铁吸附，以防止在料带上的胶点发生抖动，因此在侧导板上安装磁铁的设置，可以更好地抬料，送料更为顺畅。
5、在喷胶控制装置的控制下实现定量精准的喷胶，并且在常温下可快速生产粘胶固化铁芯。
6、在抬升装置设置的情况下实现粘胶喷涂装置上下升降活动，并且可实现转子铁芯或定子铁芯的生产，回转粘接的铁芯生产装置中使用并可靠生产层叠铁芯。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描 述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员所获得的所有其他实施例，都属于本发明保护的范围。
图1-图16是本发明的第一实施例，且第一实施例所描述的是电机层叠铁芯的生产设备，在第一实施例中，电机层叠铁芯的生产设备具体包括如下：
电机层叠铁芯由多个铁芯片相互层叠并粘接而形成，各铁芯片在金属料带10上冲裁成预定形状而形成。生产设备包括上模组件1、下模组件2和粘胶喷涂装置3。

粘胶喷涂装置3设置于上模组件1和下模组件2中的至少一者上，粘胶喷涂装置3与金属料带10上用于铁芯片成型部分的表面对应地设置，所述粘胶喷涂装置3包括喷胶板30、第一模板31和第二模板32，喷胶板30为环体结构，一般采用圆环体，第一模板31设置于喷胶板30和第二模板32之间，并且芯轴压板33置于喷胶板30的内孔中，喷胶板30的内壁形成第一凸台304，芯轴压板33的外壁形成有第二凸台331，第二凸台331压制于第一凸台304上，并且多个螺栓的螺杆分别贯穿芯轴压板33和第一模板31后与第二模板32的螺纹孔螺纹连接，可以将该处螺栓设定为九个，第二模板32上固定有镶环34，在利用多个螺栓的螺杆分别贯穿镶环34与第二模板32的螺纹孔螺纹连接，并且该处螺栓可设定为至少十个，第一模板31和喷胶板30置于镶环34的内腔中，镶环34的内壁形成有凸起341，喷胶板30上形成有台阶303，且凸起341限位于台阶303上，进而通过芯轴压板33和镶环34的设置使得喷胶板30、第一模板31和第二模板32得到相互连接，从而使得结构紧凑可靠，喷胶板30、第一模板31和第二模板32均为金属板，喷胶板30、第一模板31和第二模板32之间通过橡胶密封圈35密封，以防止漏胶。所述粘胶喷涂装置3设置于下模组件2的凹腔内。

第一模板31的正面面形成有多个分别与各第一喷胶口301连通的第一分流通道312、与各第一分流通道312相连通的第一进胶通道313、以及分别与各第二喷胶口302对应连通的多个过 渡通道311，第二模板32的正面形成有多个分别与各过渡通道311连通的第二分流通道321、以及与各第二分流通道321相连通的第二进胶通道322；当第三进胶通道323输入粘胶后，粘胶通过第一进胶通道313和第一分流通道312进入至第一喷胶口301，然后再通过第一喷胶口301的直段通道306喷出；当第二进胶通道322输入粘胶后，粘胶经第二分流通道321和过渡通道311后进入至第二喷胶口302，然后再通过第二喷胶口302的直段通道306喷出，因此金属料带10上用于铁芯片成型部分的表面与喷胶板30的上表面接触后，第一喷胶口301和第二喷胶口302所喷出的粘胶直接涂覆于金属料带10上用于铁芯片成型部分的表面上，第一进胶通道313贯通地设置于第一模板31上，第二进胶通道322贯通地设置于第二模板32上。
另一实施方式，可在第二模板(32)上设置避让孔或避让缺口，以使第一进胶通道313的下端口露出，以实现第一进胶通道313可直接与进胶用管道进行对接。
本实施例中，第一模板31的正面形成有第一分流腔314，第一分流腔314与第一进胶通道313相连通，各第一分流通道312分别与第一分流腔314连通，第一分流腔314用于将经第一进胶通道313和第三进胶通道323输入的粘胶进行汇集，当第一分流腔314的粘胶被填充满后，再进入至各第一分流通道312中，以使得第一喷胶口301具有较大压力喷出粘胶，第一分流腔314对该单一区域的喷胶口所喷出的胶量、压力等进行限制，实现每个部位定量喷胶精准。
本实施例中，第二模板32的正面形成有第二分流腔325，第二分流腔325与第二进胶通道322相连通，各第二分流通道321分别与第二分流腔325连通，第二分流腔325用于将第二进胶通道322输入的粘胶进行汇集，当第二分流腔325的粘胶被填充满后，再进入至各第二分流通道321中，以使得第一喷胶口301具有较大压力喷出粘胶，第二分流腔325对该单一区域的喷胶口所喷出的胶量、压力等进行限制，实现每个部位定量喷胶精准。
本实施来中，第一喷胶区36和第二喷胶区37均呈环形结构，一般采用圆环形，且多个第一喷胶口301呈等间距均匀分布，多个第二喷胶口302呈等间距均匀分布，其结构设置使得涂覆于金属料带10上用于铁芯片成型部分的表面上胶点分布均匀，达到各铁芯片之间固定连接稳定可靠。
本实施例中，第一模板31的正面和第二模板32的正面均形成有多个环形阵列设置的连通槽324；其设置使得多个第一分流通道312之间通过第一模板31上的各连通槽324连通，多个第二分流通道321之间通过第二模板32上的各连通槽324连通，从而实现对某一分流通道内的粘胶量过多时可通过连通槽324分流至对应模板上的其它分流通道中。
具体地，第一模板31上的各连通槽324分别位于多个第一分流通道312之间，以使多个第一分流通道312通过连通槽324连通，第一模板31上的各连通槽324位置分别与环形结构的第一喷胶区36位置对应地设置，第一喷胶口301通过第一模板31上的连通槽324与第一 分流通道312连通，第二模板32上形成有与第一进胶通道313连通的第三进胶通道323，第二进胶通道322和第三进胶通道323贯穿地设置于第二模板32上；当第三进胶通道323输入粘胶时，粘胶经第一进胶通道313、第一分流通道312、第一分流腔314和连通槽324进入至第一喷胶口301，最后通过第一喷胶口301的直段通道306喷出，并直接涂覆于金属料带10上用于铁芯片成型部分的表面上。
具体地，第二模板32上的各连通槽324分别位于多个第二分流通道321之间，以使多个第二分流通道321通过连通槽324连通，第二模板32上的各连通槽324位置分别与环形结构的第二喷胶区37位置对应地设置，第二喷胶口302通过过渡通道311和第二模板32上的连通槽324与第二分流通道321连通；当第二进胶通道322输入粘胶时，粘胶经第二分流通道321、第二分流腔325、连通槽324和过渡通道311进入至第二喷胶口302，最后通过第二喷胶口302的直段通道306喷出，并直接涂覆于金属料带10上用于铁芯片成型部分的表面上。
上述中，第一模板31的正面为朝向喷胶板30的一侧面，第二模板32的正面为朝向第一模板31的一侧面。
本实施例中，还包括用于金属料带10在步进式输送时导向和限位的定位结构，定位结构可设置为两个，并且两个定位结构分别设置于下模组件2上的左右两侧，其中，定位结构包括侧导板7和磁铁72，侧导板7上形成有定位槽71，磁铁72嵌设于定位槽71的上内壁，金属料带10的侧边缘位于定位槽71内，所述磁铁72通过其磁力作用将所述金属料带10与所述下模组件2的上表面分离，以保证分离后金属料带10被磁铁72吸附，以防止在金属料带10抖动，进一步防止在金属料带10上的胶点发生抖动，避免粘在金属料带10上的胶点形状发生变化，因此在侧导板7和磁铁72的设置下抬料和送料更为顺畅，由于步进式送料采用在所述生产设备的两端分别设置辊式送料机9，并采用前推后拉的方式进行金属料带10的输送，所以金属料带10被磁铁72吸附，起到抬料作用，也可在吸附的情况下金属料带10作步进式输送，由于金属料带10采用硅钢片，所以可被磁铁72吸附。
本实施例中，上模组件1和下模组件2之间形成有金属料带输送通道，金属料带输送通道的进料端前方设置有喷嘴8，喷嘴8对金属料带10表面喷涂冲压油与促进剂混合的混合液体，混合液体分别与第一喷胶口301和第二喷胶口302所喷出的粘胶混合，以使多个铁芯片相互层叠并粘接而形成电机层叠铁芯，该混合液体具有催化粘胶的功能，并且粘胶为丙烯酸酯类的厌氧胶，从而相互复合后可在常温环境下实现固化，以实现多个铁芯片之间的粘接。
本实施例中，还包括第一喷胶控制装置13和第二喷胶控制装置14，第一喷胶控制装置13和第二喷胶控制装置14均包括控制器131、胶筒132和粘胶控制设备133，控制器131中的气体减压阀通过气路管与胶筒132的进气端口对接，粘胶控制设备133与控制器131中的 控制模块相连并受其控制，胶筒132的出料端口通过管道与粘胶控制设备133的进胶口对接，粘胶控制设备133的出胶口安装有压力传感器134，压力传感器134与控制器131中的控制模块相连并受其控制，当管道堵塞压力传感器134检测到压力过大，压力传感器134报警，当管道接头密封失效，导致压力过小，压力传感器134报警；其中，第一喷胶控制装置13的粘胶控制设备133出胶口通过管道与第三进胶通道323对接，第二喷胶控制装置14的粘胶控制设备133出胶口通过管道与第二进胶通道322对接，其中，控制模块采用PLC控制器，气体减压阀采用电气比例减压阀，PLC控制器根据冲床冲压速度、出胶量设定值来控制电气比例减阀的进气压力、以及控制第一喷胶控制装置13的粘胶控制设备133工作而输出粘胶至第一喷胶口301和控制第二喷胶控制装置14的粘胶控制设备133工作而输出粘胶至第二喷胶口302，从而使得每一次喷胶的喷胶量得到精准的控制，粘胶控制设备133工作而输出的粘胶由胶筒132输出粘胶而提供，粘胶控制设备133采用螺杆泵。
本实施例中，还包括抬升装置4；抬升装置4包括抽板42、以及固定于第二模板32上的抽板垫块41，抽板垫块41的底面和抽板42的顶面分别通过多个相互等间距间隔设置的配合槽412而形成多个配合齿块411，且配合齿块411对应插入配合槽412内；抽板垫块41上的配合槽412一侧壁和抽板42上的配合槽412一侧壁相互贴合，且相互贴合的两侧壁均为倾斜角度一致的斜面413，抽板42的延伸段贯穿通道后与位于下模组件2上的气缸43连接；当一个电机层叠铁芯或铁芯片冲裁完成之后，开始冲第二个电机层叠铁芯或铁芯片时，气缸43抽动抽板42，使得配合齿块411配置至配合槽412内，从而迫使喷胶板30低于下模组件2顶面1mm至2mm，这样即使之前在喷胶板30上有残留的粘胶，也不会粘在金属料带上，致使输送过程中的金属料带保持清洁，如在金属料带上粘附其余粘胶容易导致粘接形成的铁芯垂直度、平面度、圆度等形位公差无法符合要求，致使铁芯报废的情况发生，多个螺栓分别贯穿依次镶环34和第二模板32后与抽板垫块41的螺纹孔螺纹连接，该处螺栓可设置为至少五个。
抽板垫块41上设置有空腔，该空腔用于容纳对接第二进胶通道322和第三进胶通道323的接头。
本实施例中，导向组件5包括固定于抽板垫块41上的导柱52和安装于下模组件2上的导套51，导柱52插入导套51内，当抽板垫块41作上下升降运动时，导柱52在导套51内作伸缩运动，使得粘胶喷涂装置3升降运动稳定可靠，并且始终保持上下方向运动，导套可采用滚珠导套51，以使得导柱52在导套51内活动更为顺畅。
本实施例中，复位组件6包括安装于下模组件2上的套筒61、以及置于套筒61内的弹簧62和柱体63，柱体63与抽板垫块41连接，弹簧62的两端分别与套筒61和柱体63连接， 当气缸43抽动抽板42，使得粘胶喷涂装置3上升后，再次抽动抽板42使得配合齿块411与配合槽412内对应，此时，在弹簧62的作用下驱动粘胶喷涂装置3下移，且配合齿块411对应陷入配合槽412内，该结构设置实现粘胶喷涂装置3复位下移的功能。
基于上述电机层叠铁芯的生产设备进行铁芯生产，具体方法步骤如下：
金属料带10以连续步进式向落料方向输送，并在进入生产设备的上模组件1和下模组件2之间前，对金属料带10的上表面进行喷涂用于催化粘胶的混合液体，催化指的是混合液体与粘胶可发生化学反应。
金属料带10在生产设备的上模组件1和下模组件2之间，以连续步进式向落料方向输送，使铁芯片预成型区贴合于生产设备中位于落料工位前的粘胶喷涂装置3上，第一喷胶控制装置13中的胶筒132内粘胶通过粘胶控制设备133输送至粘胶喷涂装置3的第一喷胶口301处，第二喷胶控制装置14中的胶筒132内粘胶通过粘胶控制设备133输送至粘胶喷涂装置3的第二喷胶口302处，并使第一喷胶口301和第二喷胶口302所喷出的粘胶粘附在铁芯片预成型区的下表面，并在铁芯片预成型区的下表面均匀分布有胶点117。
金属料带10在步进式输送过程中，对金属料带10上涂覆有粘胶的铁芯片预成型区作冲裁处理，以成型铁芯片，并落料至落料通道21内与其内部的铁芯片叠片组顶面之间通过粘胶与混合液体接触而固化粘接，以形成层叠铁芯；固化粘接时，在15℃-35℃的温度环境中经过10s-3min的时间内完成粘接，以及所成型的铁芯片受上模组件1的成型模施压，以及铁芯片叠片组受液压缸的背压力和锁紧圈的包紧力作用下，以使所成型的铁芯片与铁芯片叠片组顶面之间紧密地粘接。其中，15℃-35℃的温度范围一般为常温温度范围，但是本实施例优选20℃-25℃；时间范围在10s-3min完成快速粘接，然而10s左右或10S以上的固化状态为初步固化，初步固化实现人力无法分离的效果，3min可达到完全固化状态。
根据以上所述的电机层叠铁芯的生产方法，粘胶涂覆后胶点位于铁芯片的外边缘处，或者
粘胶涂覆后胶点位于铁芯片上的轴孔边缘处，或者
粘胶涂覆后胶点位于铁芯片上的磁钢槽周边，或者
粘胶涂覆后铁芯片上的多个齿部中的每个齿部分别粘附至少一个胶点，当齿部较长时可在每个齿部上粘附两个或三个胶点，齿部由在转子或定子上成型多个槽形后而形成，且上述胶点位置的设置使得电机铁芯的振动和噪音得到大幅度降低。
图17-图21所示是本发明的第二实施例，且第二实施例所描述的是电机层叠铁芯的生产方法，在第二实施例中，本发明电机层叠铁芯的生产方法包括以下方式：
在第一实施例所述的电机层叠铁芯的生产设备及其生产方法的基础上制造转子铁芯和定 子铁芯，所述生产设备上的料带进入端设置混合液体喷涂工位，所述生产设备依次包括用于成型缺口成型孔一112、缺口成型孔二113和定子方槽111的成型工位一102，用于成型通风孔114和缺口成型孔三125的成型工位二103，用于成型转子磁钢槽115、转子中心孔116及再成型定子方槽111的成型工位三104，具有粘胶喷涂装置3的喷胶工位一105，用于成型转子铁芯片118的落料工位一106，用于成型槽形孔120及长形孔122的成型工位四107，用于成型定子槽形和定子轴孔的成型工位五108，具有粘胶喷涂装置3的喷胶工位二109，用于成型定子铁芯片124的落料工位二110，利用上述装置成型转子铁芯片和定子铁芯片，并在铁芯片落料前进行涂胶，其具体生产步骤如下：
步骤S1，金属料带10以连续步进式向落料方向输送，并在进入生产设备的上模组件1和下模组件2之间前，对金属料带10的上表面进行喷涂用于催化粘胶的混合液体；因为，混合液体与丙烯酸酯类的厌氧胶相接处，可快速产生化学反应，从而为了使得多个铁芯片成型后可在生产设备内层叠并在上述时间和温度条件下固化粘接作预先准备。
步骤S2，金属料带10在生产设备的上模组件1和下模组件2之间，以连续步进式向落料方向输送，并对金属料带10多列冲裁成型区101进行同步冲裁，以在各成型区成型带缺口的转子中心孔116、环绕转子中心孔116的多个通风孔114和多个转子磁钢槽115、以及位于多个转子磁钢槽115外围且环形阵列设置的多个定子方槽111，且转子磁钢槽115位于通孔的外围，进而通过转子磁钢槽115外围界定形成转子铁芯片预成型区；其步骤为转子铁芯片118冲裁成型提供对应结构及条件，为后转子铁芯片118成型作预先准备。
步骤S3，金属料带10连续步进式输送过程中，转子铁芯片预成型区贴合于生产设备中位于转子落料工位前的粘胶喷涂装置3上，第一喷胶控制装置13中的胶筒132内粘胶通过粘胶控制设备133输送至粘胶喷涂装置3的第一喷胶口301处，第二喷胶控制装置14中的胶筒132内粘胶通过粘胶控制设备133输送至粘胶喷涂装置3的第二喷胶口302处，并使第一喷胶口301和第二喷胶口302所喷出的粘胶粘附在转子铁芯片预成型区的下表面，并且各通风孔114之间和各转子磁钢槽115之间分别均匀分布有胶点117，其中，各第一喷胶口301点位分别与各通风孔114之间的胶点点位对应地设置，各第二喷胶口302点位分别与各转子磁钢槽115之间的胶点点位对应地设置，达到粘胶可有效涂覆，使得粘胶也与促进剂达到有效接触。
步骤S4，在金属料带10连续步进式输送过程中，对喷涂有胶点117的转子铁芯片预成型区进行冲裁，以形成转子铁芯片118，并落料至落料通道21内与其内部的转子铁芯片叠片组顶面之间通过粘胶与混合液体接触而常温固化粘合固定，以形成转子铁芯，在落料通道21的转子铁芯片叠片组下端面具有支撑液压缸支撑，并且每冲裁一片转子铁芯片118控制支撑 液压缸下降一个转子铁芯片118厚度的距离，以便于下次冲裁成型的铁芯片进行叠片粘接，常温指的是15℃-35℃，本实施例优选20℃-25℃。
步骤S5，金属料带10连续步进式输送过程中，对落料孔119外围冲裁形成多个环形阵列设置的槽形孔120，槽形孔120上靠近落料孔119的一端形成有长形孔122；其步骤的成型为定子槽形123的成型作预先准备，避免直接成型而发生变形。

步骤S24,金属料带10连续步进式输送过程中，依缺口成型孔一112和缺口成型孔三分布的中心位置处冲裁成型带缺口的转子中心孔116。
