Description

粘胶式铁芯的层叠方法及生产设备、粘胶式层叠铁芯 技术领域
本发明涉及电机铁芯制造技术领域,具体涉及一种粘胶式铁芯的层叠方法、一种粘胶式层叠铁芯的生产设备、一种粘胶式层叠铁芯。
背景技术
现在市面上出现的粘胶铁芯,尤其是新能源汽车驱动电机粘胶铁芯,其是利用生产设备将多片铁芯片成型,并利用提前涂覆在铁芯片表面的粘胶使得多个铁芯片相互粘接而形成粘胶铁芯。
现有的粘胶铁芯生产设备中,例如存在如公开号为CN114884292B的一种电机粘胶铁芯制造装置及其制造方法,采用在进入连续冲裁模具前对料带进行大面积喷洒催化剂,在模内利用喷胶机构进行点胶的方式,通过催化剂和胶水相互混合来实现铁芯叠片的相互层叠;该制造装置虽然能够使得催化剂和胶水充分混合提高粘接牢固可靠性,但大面积喷洒催化剂也一定程度上造成浪费,导致成本增加,并且若催化剂从铁芯片材的外形轮廓向外侧溢出,则催化剂会附着于涂布催化剂后进行外形冲压的模具上,或成为模具产生污染的原因,有可能损害模具的正常动作;并且,该制造装置中的喷胶机构是采用气压喷涂方式,虽实现了定量喷胶,但气压的经常变化也容易造成点胶过程中的气压不稳定,依旧会对点胶的精准度造成影响。
又例如存在如公开号为CN110100377B的层叠铁芯的制造方法及层叠铁芯的制造装置,其分设临时层叠工序和正式层叠工序,在模具中形成了层叠体后,在模具外进行各铁芯部件的粘接及层叠;该装置虽然避开了在模具内向金属板供给粘接剂时会出现的各种问题,但模外叠片在一定程度上增加了层叠铁芯生产工序,降低了层叠铁芯的生产效率,并且无法保证层叠铁芯点胶精度和层叠精度。

实施例1
一种粘胶式铁芯的层叠方法,如图1、图6-图12所示,包括步骤:
在落料工序前,对连续的铁芯片材2进行冲裁;
判断是否存在第一喷胶信号;
若存在第一喷胶信号,则解析第一喷胶信号,以获取第一喷胶信号中表征压电喷胶装置20各喷胶口21的电压值;
将所述电压值配置给各喷胶口21,以形成配置于喷胶口21形变部的对应电压值的电场;
根据所述电场的控制所述形变部产生形变,形成对喷胶口21内粘合剂挤压,以在未落料之前的冲裁工位中向朝向落料凹模121的铁芯片材2的第一表面供应第一粘合剂;其中,第一粘合剂用以形成铁芯相互层叠的粘合力。
本发明中采用压电喷胶的方式对铁芯片材2的第一表面供应第一粘合剂,以替代传统采用全面喷洒第一粘合剂的方式,一方面解决了全面喷洒出现的浪费、成本增加的问题;另一方面,本实施例中进胶水由电压值控制,通过控制配置给各喷胶口21的电压值来控制压电喷胶装置20的喷胶量,区别于现有采用气压喷涂的方式容易因为气压不稳定造成点胶量的差异和精准度的降低,本实施例中由于电压值的大小可以精确控制,因此胶点大小可控,在一定范围内可以做到非常小,稳定的电压还能够保证胶点大小的一致性和形状规则,有效避免产品出现的溢胶问题。
在粘胶式铁芯层叠方法中的冲裁工位包括有落料前的冲裁工位和落料工位;其中,落料前的冲裁工位包括在铁芯片材2上冲裁出槽和孔等相关结构,落料工位包括将整个成品薄片在铁芯片材2上冲裁落料形成铁芯。
在一实施例中,在未落料之前的一个冲裁工位中向朝向落料凹模121的铁芯片材2的第一表面供应第一粘合剂。
进一步地,在所述冲裁工位中向朝向落料凹模121的铁芯片材2的第一表面多次供应第一粘合剂。
可以理解为,本实施例可以控制压电喷胶装置20对铁芯片材2第一表面预定位置一次性喷胶完成,也可以控制压电喷胶装置20在同一冲裁工位处分多次喷胶以组合实施该预定位置的喷胶。
进一步地,所述冲裁工位为落料工位,即在未执行落料之前的落料工位中向朝向落料凹模121的铁芯片材2的第一表面供应第一粘合剂。
具体的,相较于先喷涂第一粘合剂再执行冲裁槽和孔等相关结构的方式,本实施例中采用在落料工位处喷涂第一粘合剂的方式,能够有效避免喷涂在铁芯片材2上的第一粘合剂在执行冲裁槽和孔等相关结构过程中发生粘合剂向外溢出的现象,避免粘合剂粘着于模具造成污染,保证落料前的冲裁工序的正常动作;此外,也可有效避免在冲裁过程中第一粘合剂提前固化失效而产生不必要的浪费,过早喷涂粘合剂对环境温度的要求会越高,增加制造成本。
进一步地,还包括:所述压电喷胶装置20在所述铁芯片材2经所述落料凹模121定位后施加所述第一粘合剂,利用定位结构提升其喷胶精准度。
在一实施例中,在未落料之前的多个冲裁工位中向朝向落料凹模121的铁芯片材2的第一表面供应第一粘合剂。即 本实施例可以控制压电喷胶装置20在不同冲裁工位处进行喷胶以组合实施该预定位置的喷胶。
进一步地,所述多个冲裁工位中包括落料工位。
在一实施例中,在同一次喷胶过程,至少存在两不同电压值作用于位于不同位置的同种喷胶口21形变部,以形成第一表面上不同区域的不同喷胶量。
在又一实施例中,在同一次喷胶过程,至少存在不同位置的两种喷胶口21形变部在同一电压值作用下,形成第一表面上不同区域的相同喷胶量。
通过上述设置,能够利用电压值作用调节喷胶口21大小以调控喷胶口21的喷胶量,不同位置的喷胶口21可独立工作,提升喷胶效率和喷胶质量。
如此,喷胶时,压电喷胶装置20可以不与铁芯片材2表面直接接触,喷胶口21的喷胶量也能够与铁芯的尺寸及外形结构设计相适配,避免铁芯在叠压过程中出现粘合剂外溢的问题的同时保证胶量的均匀适量。
其中,压电喷胶装置20上形成有若干喷胶口21,所述喷胶口21包括压电元件211、储胶仓212和压电喷头213,当导通压电元件211的流经电流时,压电元件211收缩变形以挤压储胶仓212,储胶仓212发生形变将其内部的胶水向压电喷头213处挤压,而后胶水经压电喷头213喷出至铁芯片材2表面的对应位置;其中,所述储胶仓212即为所述形变部。
可以理解为,通过将电流直接转换成压电喷胶装置20的形变来挤压出胶,实现更快响应和更为精准的喷胶。
具体步骤包括:
在喷胶信号的控制下,导通向压电喷胶装置20提供的驱动电流,使得压电喷胶装置20的压电元件211收缩挤压储胶仓212内的胶水;
当切断向压电喷胶装置20提供的驱动电流时,压电元件211延伸以将胶滴推出压电喷头213;
当驱动电流恢复时,压电元件211再次进行收缩以进入下一次喷射胶水的准备状态。
如此,胶水能够得到精确控制,即精确控制胶点的喷射方向和形状,形成稳定的胶点;且根据压电喷胶装置20能够通过电流输出的曲线而精准控制,可实现第一粘合剂和第二粘合剂在模内快速喷涂,并能够与模具的冲裁速率和落料速率更好的适配。
在一实施例中,结合图2、图6-图11所示,还包括:控制点胶装置对铁芯片材2的第二表面供应第二粘合剂;其中,所述铁芯片材2的第二表面朝向落料凹模121。
具体的,在本实施例中,层叠式铁芯粘胶生产方法包括步骤:
判断是否存在第二喷胶信号;
若存在第二喷胶信号,则解析第二喷胶信号,以获取第二喷胶信号中指示的喷胶量;
基于所述喷胶量,控制点胶装置在冲裁工位中向落料凸模111的铁芯片材2的第二表面供应第二粘合剂;其中,第二粘合剂用以与第一粘合剂结合以形成铁芯相互层叠的粘合力。
其中,点胶装置包括储胶罐、喷胶盘以及螺杆泵,其中,螺杆泵安装于储胶罐和喷胶盘之间,螺杆泵控制储胶罐供向喷胶盘的进胶量,使进胶量稳定,胶水进入所述喷胶盘内的进胶通道后分流至各个出胶头处,若干出胶头的排布方式与铁芯片轮廓相对应,以通过若干出胶头向铁芯片材2的第二表面施加第二粘合剂。
为了提高出胶响应速度和喷胶精准度,在另一些优选实施例中,结合图3、图6-图11所示,还包括步骤:
判断是否存在第二喷胶信号;
若存在第二喷胶信号,则解析第二喷胶信号,以获取第二喷胶信号中表征压电喷胶装置20各喷胶口21的电压值;
将所述电压值配置给各喷胶口21,以形成配置于喷胶口21形变部的对应电压值的电场;
根据所述电场的控制所述形变部产生形变,形成对喷胶口21内粘合剂挤压,以在冲裁工位中向朝向落料凸模111的铁芯片材2的第二表面供应第二粘合剂;其中,第二粘合剂用以与第一粘合剂结合以形成铁芯相互层叠的粘合力。
在一实施例中,在一个冲裁工位中向朝向落料凸模111的铁芯片材2的第二表面供应第二粘合剂。
进一步地,在所述冲裁工位中向朝向落料凸模111的铁芯片材2的第二表面多次供应第二粘合剂。
可以理解为,本实施例可以控制压电喷胶装置20对铁芯片材2第二表面的预定位置一次性喷胶完成,也可以控制压电喷胶装置20在同一冲裁工位处分多次喷胶以组合实施该预定位置的喷胶。
进一步地,所述冲裁工位为落料工位。
其中,第二喷胶信号与落料信号同步,即落料工序和压电喷胶装置20供应第二粘合剂的步骤为同步进行,控制落料凸模111和落料凹模121合模时,控制压电喷胶装置20执行喷胶。
进一步地,还包括:所述压电喷胶装置20在所述落料凸模111抵触所述第二表面之前或正抵触所述第二表面时施加所述第二粘合剂。即本实施例采用在执行落料的同时进行第二粘合剂的喷涂;由于压电喷胶装置20具有动作精度高,响应速度快稳定性好等优点,因此,本实施例中将喷胶速率和冲裁速度相匹配,即在冲裁铁芯片材2的其他区域的结构的同时能够快速完成该处区域的喷胶和落料,使得压电喷胶装置20能够更好的适配模具的整体冲裁速度的同时保证喷胶的精准度,提高生产设备1整体的生产速率。
进一步地,还包括:所述压电喷胶装置20在所述铁芯片材2经所述落料凹模121定位后施加所述第一粘合剂和第二粘合剂;即配置铁芯片材2位于同一个落料凹模121外形定位下完成铁芯片材2的第一表面和第二表面的喷胶,以进一步保证压电喷胶装置20喷胶精准度,以进一步保证相邻铁芯相互层叠时第一粘合剂的胶点位置和第二粘合剂的胶点位置准确重合。
在又一实施例中,在多个冲裁工位中向朝向落料凸模111的铁芯片材2的第二表面供应第二粘合剂。即本实施例可以控制压电喷胶装置20在不同冲裁工位处进行喷胶以组合实施第二表面上预定位置的喷胶。
进一步地,所述多个冲裁工位中包括落料工位。
在一实施例中,所述第一粘合剂和第二粘合剂均呈点状施加至铁芯片材2表面,且相邻两铁芯相互粘合层叠时其上胶点相互重合。
在又一实施例中,第一粘合剂为冲压油与促进剂混合的混合液体,具有催化粘胶的功能,第二粘合剂为粘胶,且粘胶为丙烯酸酯类的厌氧胶;第一粘合剂和第二粘合剂相互混合后可在常温环境下实现固化,以使多个铁芯相互层叠并粘接而形成电机层叠铁芯。
具体的,第一粘合剂和第二粘合剂的喷涂方式都包含多个喷胶点,具体的喷胶点数量根据铁芯片的槽形数量确定,合理布置胶点位置,保证铁芯片上喷胶面积充足的同时,避免叠压时溢胶;并且压电喷胶装置20由电流控制,能够实现胶水对应点喷涂,且第一粘合剂的喷涂点与第二粘合剂的喷涂点的数量相等,且点位之间是相互对应的关系,使喷涂的第一粘合剂点位与所喷涂的第二粘合剂点位在叠压时完全接触并充分混合,实现粘接剂的快速固化,避免浪费粘合剂,降低成本。
应当理解,第二粘合剂的喷胶点的数量设置也可以比第一粘合剂的喷涂点的数量多,目的是多余的第二粘合剂点位不与第一粘合剂结合,而是直接与铁芯片接触,使不与第一粘合剂结合的第二粘合剂在铁芯片落料、叠压和出料后,在自然条件下进行固化,在室温条件下实现催化快速固化与自然固化相结合,有效增加各铁芯片层之间的固化连接强度,提高铁芯的整体结构强度,为电机铁芯在使用时提供可靠的保障。
为了提高压电喷胶装置20的喷胶精准度,在一实施例中,还包括步骤:
获取铁芯片材2的厚度;
根据所述厚度得到铁芯相互层叠时所需胶量;
基于所述胶量确定所述压电喷胶装置20各喷胶口21的喷胶量,从而确定各喷胶口21对应的电压值。
其中,材料的厚度数据可以从材料质保书上获得,因此可通过工人输入来获取铁芯片材2的厚度;在另一些实施例中,也可通过配置在线料厚测量装置对厚度进行测定,以便于更精准的获得当前铁芯片材2的厚度数据。
进一步地,根据所述厚度得到铁芯相互层叠时所需胶量的步骤包括:
将所述厚度与预设厚度阈值进行匹配;其中,每个预设厚度阈值匹配不同的预设胶量;
若所述厚度与所述预设厚度阈值相匹配,则获取所述预设厚度阈值对应的预设胶量,作为所述胶量。
通过进一步精准调控压电喷胶装置20的喷胶量,保证喷胶均匀适量的同时避免铁芯在叠压过程中出现粘合剂外溢的问题,提高层叠铁芯的质量。
在又一实施例中,还包括步骤:
获取铁芯片材2上的铁芯预成型区域的尺寸;
根据所述尺寸得到铁芯片材2上胶点的分布形状;
基于所述分布形状确定所述压电喷胶装置20的喷胶位置,从而将电压值配置给对应位置的喷胶口21。
通过上述设置,可根据铁芯片材2的厚度尺寸来调整喷胶口21的喷胶量,根据铁芯的结构设计的不同调整喷胶口21的工作数量;例如,若铁芯片材2厚度或尺寸增加,则可适当调整喷胶口21孔径增大且提高其出胶密集度,如此增加喷涂至铁芯片材2表面的胶量;若铁芯片材2厚度或尺寸减小,则可调整喷胶口21孔径减小且减小其出胶密集度,如此减少喷涂至铁芯片材2表面的胶量。
在又一实施例中,所述压电喷头213表面形成有可变尺寸的出胶孔2131,通过调节所述出胶孔2131大小以控制所述压电喷头213的喷胶量。

本发明中进胶水由电压值控制,通过控制配置给各喷胶口21的电压值来控制压电喷胶装置20的喷胶量,并且由于电压值的大小可以精确控制,因此胶点大小可控,在一定范围内可以做到非常小,稳定的电压还能够保证胶点大小的一致性和形状规则,有效避免产品出现的溢胶问题。
在粘胶式铁芯层叠方法中的冲裁工位包括有落料前的冲裁工位和落料工位;其中,落料前的冲裁工位包括在铁芯片材2上冲裁出槽和孔等相关结构,落料工位包括将整个成品薄片在铁芯片材2上冲裁落料形成铁芯。

进一步地,在所述冲裁工位中向朝向落料凸模111的铁芯片材2的第二表面多次供应第二粘合剂。

进一步地,所述冲裁工位为落料工位。
其中,第二喷胶信号与落料信号同步,即落料工序和压电喷胶装置20供应第二粘合剂的步骤为同步进行,控制落料凸模111和落料凹模121合模时,控制压电喷胶装置20执行喷胶。
进一步地,还包括:所述压电喷胶装置20在所述落料凸模111抵触所述第二表面之前或正抵触所述第二表面时施加所述第二粘合剂。即本实施例采用在执行落料的同时进行第二粘合剂的喷涂;由于压电喷胶装置20具有动作精度高,响应速度快稳定性好等优点,因此,本实施例中将喷胶速率和冲裁速度相匹配,即在冲裁铁芯片材2的其他区域的结构的同时能够快速完成该处区域的喷胶和落料,使得压电喷胶装置20能够更好的适配模具的整体冲裁速度的同时保证喷胶的精准度,提高生产设备1整体的生产速率。
此外,本实施例有效避免第二粘合剂提前固化失效而产生不必要的浪费,过早喷涂粘合剂对环境温度的要求会越高,增加制造成本。
进一步地,还包括:所述压电喷胶装置20在所述铁芯片材2经所述落料凹模121定位后施加所述第一粘合剂和第 二粘合剂;即配置铁芯片材2位于同一个落料凹模121外形定位下完成铁芯片材2的第一表面和第二表面的喷胶,以进一步保证压电喷胶装置20喷胶精准度,以进一步保证相邻铁芯相互层叠时第一粘合剂的胶点位置和第二粘合剂的胶点位置准确重合。
在又一实施例中,在多个冲裁工位中向朝向落料凸模111的铁芯片材2的第二表面供应第二粘合剂。即本实施例可以控制压电喷胶装置20在不同冲裁工位处进行喷胶以组合实施第二表面上预定位置的喷胶。

步骤S2,铁芯片材2连续步进式输送过程中,将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;当获取到喷胶信号后,控制压电喷胶装置20向粘胶喷涂装置3供胶,即控制第一压电喷胶结构201向第一粘胶喷涂装置供胶以对铁芯片材2的第一表面涂覆第一粘合剂,控制第二压电喷胶结构202向第二粘胶喷涂装置供胶以对铁芯片材2的第二表面涂覆第二粘合剂;粘胶经压电喷胶装置20输送至粘胶喷涂装置3的第一喷胶口301、 第二喷胶口处302,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表面;并且各通风孔2114之间和各转子磁钢槽2115之间分别均匀分布有胶点2117,其中,各第一喷胶口301点位分别与各通风孔2114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2115之间的胶点点位对应地设置,达到粘胶可有效涂覆,使得第一粘合剂与第二粘合剂有效接触。
步骤S3,在铁芯片材2连续步进式输送过程中,对喷涂有胶点2117的转子铁芯片预成型区进行冲裁,以形成转子铁芯片2118,并落料至落料通道内与其内部的转子铁芯片叠片组顶面之间通过第一粘合剂与第二粘合剂接触而常温固化粘合固定,以形成转子铁芯,在本实施例中,第一粘合剂为冲压油与促进剂混合的混合液体,具有催化粘胶的功能,第二粘合剂为粘胶,且粘胶为丙烯酸酯类的厌氧胶;在落料通道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2118控制支撑液压缸下降一个转子铁芯片2118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,铁芯片材2连续步进式输送过程中,对落料孔2119边沿进行冲裁而形成定子中心孔,并去除长形孔2122上的一部分,使槽形孔2120与落料孔2119连通而形成定子槽形2123,进而通过定子方槽2111的外围界定形成定子铁芯片预成型区;其通过步骤S4和步骤S5的结合,避免冲裁成型的定子槽形2123发生变形,有效保证定子铁芯片2124质量,提升生产效率及品质。
步骤S6,铁芯片材2连续步进式输送过程中,定子铁芯片预成型区贴合于生产设备中位于定子落料工位前的粘胶喷涂装置3上;当获取到喷胶信号后,控制压电喷胶装置20向粘胶喷涂装置3供胶,即控制第一压电喷胶结构201向第一粘胶喷涂装置供胶以对铁芯片材2的第一表面涂覆第一粘合剂,控制第二压电喷胶结构202向第二粘胶喷涂装置供胶以对铁芯片材2的第二表面涂覆第二粘合剂;粘胶经压电喷胶装置20输送至粘胶喷涂装置3的第一喷胶口301、第二喷胶口处302,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表面,以形成胶点2117,所述胶点2117分别均匀地分布在各定子槽形2123之间、以及定子槽形2123与定子方槽2111之间;其中,各第一喷胶口301的点位分别与各定子槽形2123之间的胶点点位对应地设置,各第二喷胶口302的点位分别与定子槽形2123与定子方槽2111之间的胶点点位对应地设置,达到粘胶可有效涂覆,使得第一粘合剂与第二粘合剂有效接触。
步骤S7,在定子铁芯片2124落料前对已在落料通道内的定子铁芯片叠片组作360°/N回转,其中,N系数为18,所以回转角度为20°,N系数不限制于此,还可根据铁芯片形状作适应性调整;然后在铁芯片材2连续步进式输送过程中,对喷涂有胶点2117的定子铁芯片预成型区进行冲裁,以形成带外形缺口的定子铁芯片2124,并落料至落料通道内与定子铁芯片叠片组顶面之间通过第一粘合剂与第二粘合剂接触而常温固化粘合固定,以形成定子铁芯,在本实施例中,第一粘合剂为冲压油与促进剂混合的混合液体,具有催化粘胶的功能,第二粘合剂为粘胶,且粘胶为丙烯酸酯类的厌氧胶;在落料通道的定子铁芯片叠片组下端面具有支撑液压缸支撑,并且每冲裁一片定子铁芯片控制支撑液压缸下降一个定子铁芯片2124厚度的距离,以便于下次冲裁成型的铁芯片进行叠片粘接。
本实施例中,在步骤S2中,具体包括:
步骤S21,铁芯片材2连续步进式输送过程中,在成型区中心位置处的纵向中心线一侧冲裁成型两个相对称设置的缺口成型孔一2112、围绕缺口成型孔一2112并环形阵列设置的多个缺口成型孔二2113、以及围绕多个缺口成型孔二2113并环形阵列设置的多个定子方槽2111;
步骤S22,铁芯片材2连续步进式输送过程中,在成型区中心位置处的纵向中心线另一侧冲裁成型缺口成型孔三2125,以及在缺口成型孔一2112和缺口成型孔三2125的外围区域成型多个环形阵列设置的通风孔2114,两个缺口成型孔一2112和成型孔三呈环形阵列分布;
步骤S23,铁芯片材2连续步进式输送过程中,依各缺口成型孔二2113的位置分别成型多个带缺口的转子磁钢槽2115,以及在各定子方槽2111之间再冲裁成型定子方槽2111,其中,相邻两个转子磁钢槽2115呈倾斜设置,并相互对称;
步骤S24,铁芯片材2连续步进式输送过程中,依缺口成型孔一2112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2116。
上述步骤使得定子方槽2111、带缺口的转子磁钢槽2115、带缺口的转子中心孔2116、通风孔2114可有效成型,避免成型过程中发生变形,而且还省去了特意去设计形成缺口的步骤,提升生产效率。
本实施例中,在步骤S4与步骤S5之间具有定子外形缺口形成孔成型步骤,由环形阵列设置的多个定子方槽2111界定形成方槽成型区,方槽成型区内形成有三个环形阵列设置的缺口成型区,各缺口成型区内具有两个并列的定子方槽2111,从而对三个缺口成型区进行冲裁形成缺口成型孔四,再依据定子铁芯片2124预成型冲裁形成带外形缺口的定子铁芯片2124,其采用预成型模式,使得带外形缺口的定子铁芯片2124有效成型,避免发生变形,而且省去特意去成型外形缺口的步骤,提升生产效率。
上述实施例实现了多列转子铁芯、定子铁芯的同时生产;而且能实现定子铁芯大回转的层叠要求。
