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。
实施例：
如图1-图8所示，本实施例所描述的一种新能源汽车电机铁芯级进模的自动喷胶控制系统，包括喷嘴2和喷嘴固定板1，喷嘴固定板1上设置有安装腔13，喷嘴2置于安装腔13内，安装腔13的顶部为上端口小于下端口的锥形孔262，喷嘴2的顶端锥形体29对应插入锥形孔262内，安装腔13内设置有弹簧28，且弹簧28的两端分别与喷嘴2的锥形体29底端台阶面和安装腔13的底侧壁抵触，其中，喷嘴2的顶端锥形体29侧壁设置有喷出孔，并且锥形体29具有喷出孔的侧壁与锥形孔262内侧壁贴合，喷嘴2的顶端伸出与锥形孔262上端口，喷嘴固定板1的底端设置有与安装腔连通的进入孔111，进入孔111处通过管道连接有粘合剂供给装置，且粘合剂供给装置上安装有气压控制系统，气压控制系统对粘合剂供给装置中的粘合剂提供粘合剂推进气压、以及对供给气压进行调节，以对喷嘴的喷出孔进行粘合剂喷出的压力得到控制调节，以适应需要不同粘合剂喷出压力的设备，因此根据冲床的冲压速度不同，来自行调整空气压力分布控制柜里的减压阀(即为气压控制系统)的输送至粘合剂供给装置的胶筒处气压压力。
进一步地，喷嘴固定板1包括上板体10和下垫板11，上板体10的顶面设置有定位孔103，定位孔103内设置定位有喷嘴定位筒26，喷嘴定位筒26的顶端面与上板体顶面齐平，喷嘴置于喷嘴定位筒的内孔上端锥形孔262内，弹簧28置于喷嘴定位筒26的内孔261中，下垫板11定位于上板体10的底面，且上板体的底面设置有与喷嘴定位筒内孔连通的凹陷102，弹簧的两端分别与下垫板和喷嘴抵触，凹陷与下垫板的顶面之间形成胶道，下垫板上设置与内腔连通的进入孔111，进入孔上安装有管道连接接头，其结构将喷嘴固定板分为上板体与下垫板进行组合方式的结构，使得喷嘴便于被安装至安装腔内(即为喷嘴定位筒的内孔)，达到结构设计合理的目的。
上板体10的顶面设置凹槽101，凹槽的槽底固定有压板3，定位孔103固定于凹槽101的槽底面上，喷嘴定位筒26的中部环体263限位在定位孔103的内侧壁台阶上，且压板3进行压制固定喷嘴定位筒26的中部环体263，其为了实现在胶道内安装喷嘴时，进行对喷嘴进行定位固定的作用。
本实施例中，喷嘴定位筒26的中部环体263与定位孔103的内侧壁台阶之间设置密封件27，其结构使得喷嘴定位筒与定位孔之间的安装固定后进行密封的作用。
本实施例中，喷嘴定位筒26上位于锥形孔262底端处的内孔也为上端口小于下端口的锥孔261，锥孔的上端口直径与锥形孔的下端口直径一致，其结构便于喷嘴安装至喷嘴定位筒的内孔中，也便于钢板条料进行下压时，将喷嘴下移的作用。
本实施例中，还包括模板(凹模固定板16)，且喷嘴固定板1置于模板的模孔内，且模板上通过螺钉固定有限位板32，限位板32的台阶100限位与喷嘴固定板1的台阶100相互匹配，以对喷嘴固定板1进行限位。从而其结构设置使得在装配过程中，喷胶结构在翻转时，可以防止喷胶零部件不会掉出；同时，抽板7工作时，可以更精准地保证喷胶固定板向上窜动的距离，并对向上窜动的喷嘴固定板进行限位的作用；由于此结构设置在凹固板的正面，拆装喷胶结构均很方便，维修保养简捷；
本实施例中，模板(凹模固定板16)上方具有条料35，且条料的相对应两边侧位置设置有侧导板，侧导板33通过螺钉固定于模板(凹模固定板16)的定位槽161内，且条料位于侧导板与模板(凹模固定板16)之间，侧导板33的延伸部331设置有安装通孔332，安装通孔332内嵌设固定有磁铁。在侧导板上面，开一个安装通孔(沉孔及过孔)，把圆柱形的T型磁铁过盈的方式装配到侧导板33的安装通孔332上；此工位的喷嘴是高出凹模固板的平面；侧导板的设置用于防止料条抖动太大，确保条料的横向抖幅控制在合理的范围之内；为了送料过程中，确促条料上的胶水不被其它喷嘴碰掉，所以条料不论是静态还是动态，都必须是上浮状态；所以在喷胶结构的前、中、后三部位的侧导板上，设置了磁性的吸铁结构，磁铁对条料(硅钢片)一直有着吸附力，可以使条料在按压喷嘴瞬间之后，就可以迅速地吸附起来后呈上浮状态。
本实施例中，还包括驱动上板体10、下垫板11和喷嘴2同时上下位移的升降驱动装置，升降驱动装置安装在下端板的底面，升降驱动装置包括气缸6，下垫板11的底面定位有升降块5，升降块5的底面贴合有抽板7，升降块的底面和抽板的顶面分别通过多个相互等间距间隔设置的配合槽8而形成多个配合齿块9，且配合齿块对应插入配合槽内；升降块上的配合槽一侧壁和抽板上的配合槽一侧壁相互贴合，且相互贴合的两侧壁均为倾斜角度一致的斜面13；气缸的活塞杆端部与抽板的一端固定相连。
上述结构为升降块下移而使得上板体和下垫板也同时下移，利用其下移，将喷嘴位于凹模固定板的顶面的下方，以避免层钢板条料上冲裁出层叠铁芯中最底处的铁芯片粘附粘合剂的情况发生，待该片冲裁完成后，气缸的活塞杆伸出，促使抽板向右推移，然后利用斜面使得升降块的配合齿块底端与抽板的配合齿块顶端进行相互抵触，以得到升降块上升，此时上板体、下垫板和喷嘴同时上移，使得喷嘴的顶端突出于凹模固定板的顶面。
本实施例中，粘合剂供给装置包括胶筒20、用于压缩空气压力调制的空气压力分布控制柜22(气压控制系统)和胶筒分流器21，在下垫板处的安装孔设置有多个，且各进入孔上均安装管道连接头，胶筒分流器上具有一个进胶口211和多个分流出口212，空气压力分布控制柜的出气口25通过管道与胶筒的进胶端口对接连通，胶筒的出胶端口通过管道与胶筒分流器上的进胶口211对接连通，各分流胶口分别通过管道与各管道连接头进行对接连通；空气压力分布控制柜包括柜体和置于柜体内的至少两组减压装置，柜体上的一进气端口对接有至少两根分支气管，且分支气管通过支路管道与减压装置相连，各减压装置的出气口分别通过管道与柜体上的各出气口对接连通；减压装置包括多个减压阀23，各减压阀23的进气口通过支路管道与分支气管对接连通，其出气口通过分别通过管道与柜体上的各出气口对接连通。
基于上述粘合剂供给装置和气压控制系统，由空气动力源提供压缩空气，进入空气压力分布控制柜里的每一个减压阀，每一个减压阀对应的每一个胶筒；且胶筒与减压阀之间同样通过压缩空气管道来连接的，压缩空气把胶筒里面的胶水(粘合剂)通过空气压力把胶从胶筒中挤出来，通过胶水管道进入胶筒分流器,而胶筒分流器又有多个分流出口，每一个分流出口接连一个胶水分流管道，分流管道接连着模具内胶道的进入孔，从而进一步实现自动出胶以及在压力调整后喷出胶。
其中，胶筒与胶筒分流器21之间连接的管道处设置液体流量计31，而在液体流量计中预设上限流量数值和下限流量数值，当通过该管道处输出的液体流量超出上限流量数值或下限流量数值时，液体流量机将检测到的数据传输至冲床的PLC控制系统中，而PLC控制系统控制报警装置(声光报警装置)进行报警反馈。
基于级进模使用的冲压设备所输出的冲压速度来对应控制减压阀对输出气体的压力进行调整，使喷嘴喷出胶水的压力得到调整，其具体采用如下实施方式，减压阀采用电气比例减压阀，基于冲床的冲压速度受PLC控制系统控制，因此PLC控制系统内置程序根据所设置的冲床冲压速度数据来控制电气比例减压阀，从而通过电气比例减压阀来调整气体输出的压力，以进一步来调整喷嘴进行喷出的胶水压力，来实现喷嘴进行喷出的胶水压力随冲床的冲压速度不同而达到自行调整的目的。
综合上述结构而得到的电机铁芯制造设备，其具体包括上模座14、卸料板座15、卸料板 18、凹模固定板16和下模座17，下模座上设置有凹腔，抽板和平移板均置于凹腔内，气缸固定于下模座上，凹模固定板固定于下模座顶面位于凹腔上开口的位置处，喷嘴固定板置于凹模固定的模孔内，喷嘴固定板的顶面与凹模固定板的顶面相互齐平，上模座位于凹模固定板的上方，且卸料板座固定于上模座的底面，卸料板固定于卸料板座的底面。
当模具冲压时，冲床滑块带动上模座及卸料板座、卸料板同时冲下，此时，卸料板压住,使条料往下运动，迫使喷嘴往下移动，从而使得喷嘴的锥形头侧壁与锥形孔的内侧壁之间形成间隙，在空气压力下，胶水就顺着这个间隙喷出胶水，使得胶水粘在条料上了；当冲裁完成时，冲床滑块向上运动时，上模座、卸料板座、及卸料板随着滑块一起往上升，由于卸料板没在压住条料了,在弹簧的作用下，使喷嘴往上移动，直至喷嘴的锥面与喷嘴固定筒的锥面完全贴合时,就形成了一个封闭的腔体，以关闭喷嘴的喷出孔，其中，基于每个胶道的胶水出胶量不一样，压力也不一样，与之对应的空气压力分布控制柜里的减压阀的压力也是不一样的，且随着冲床的冲压速度不一样，空气压力分布控制柜里的减压阀的压力也是随之变化的，从而实现对喷嘴进行喷出的胶水压力进行自行调整作用，当喷出的胶水采用厌氧胶时，在条料冲压前必须在条料的顶面喷涂厌氧胶用促进剂，以便于通过级进模冲裁而出的多个铁芯片之间通过厌氧胶进行粘合后更加牢固可靠。
本发明不局限于上述最佳实施方式，任何人在本发明的启示下都可得出其他各种形式的产品，但不论在其形状或结构上作任何变化，凡是具有与本申请相同或相近似的技术方案，均落在本发明的保护范围之内。
