 本发明的最佳实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合实施例对本发明技术方案进行清楚、完整地描述。
实施例
图1示出的是陶瓷片电阻快速插装装置的结构示意图，该陶瓷片电阻快速插装装置包括机架100和安装在机架100上的引脚固定裁切组件200，以及安装在机架100上的电阻固定插装组件300，总体上，是通过引脚固定裁切组件200来固定、限位和裁切引脚料带1，通过电阻固定插装组件300来限位固定陶瓷片电阻并产生插装动作来使引脚与陶瓷片电阻完成插装。
图2示出的是本实施例所应用的引脚料带1的结构示意图，该引脚料带1包括母带1a和形成在母带1a上且均匀排列的引脚1b，插装时需要将引脚1b从母带1a上裁切下来再进行插装固定，引脚1b的末端具有用于插装固定的燕尾状结构1c。
图3示出的是用于实现将引脚1b从母带1a上裁切分离的下刀模210和裁切刀220的结构示意图，下刀模210和裁切刀220通过相向运动使下刀模210对放置在下刀模210上的母带1a产生剪切作用而使引脚1b从母带1a上分离。
下刀模210具有一个承载面210a，该承载面210a用于适配承载放置引脚料带1，同时在承载面210a上向相对侧设置条状的限位槽210b，该限位槽210b在x向上的尺寸与燕尾状结构1c相同，使得当整条引脚料带1放置在下刀模210上时，燕尾状结构1c均卡在限位槽210b内部，母带1a和引脚1b均由承载面210a支撑，同时整个引脚料带1可以在下刀模210上严限位槽210b长度方向移动。
下刀模210的承载面210a上还设置有垂直于限位槽210b的落料槽210c，该落料槽210经过限位槽210b后延伸至下刀模210的侧壁形成一个开口，落料槽210c在y向上的尺寸大于或等于引脚1b及燕尾状结构1c。
裁切刀220整体设置于下刀模210的正上方，通常由外部驱动而产生向下刀模210的往复运动（z方向）。裁切刀220具有一刃部220a，刃部220a在z方向上与落料槽210c相对应，且刃部220a在y向上的尺寸小于或等于落料槽210c，同时大于或等于引脚1b，刃部220a在x向上的尺寸与落料槽210c相同，以使得刃部220a受驱动而进入落料槽210c的同时，刃部220a与落料槽210c相贴合而形成刃口对引脚1b进行剪切；剪切掉落的引脚1b在落料槽210c的底部，由刃部220a持续下压固定便于后续插装；相应的，对引脚1b的剪切长度由落料槽210c在x方向上的尺寸确定，通常而言，落料槽210c在x方向上的尺寸不超过引脚1b的尺寸。
作为对裁切刀220的优化性改进，该裁切刀220还具有一与220a相连且整体呈L形的限位部220b，限位部220b朝向承载面210a的一面上设置有间隔的限位凸起220c，该限位凸起220c的间隔距离与燕尾状结构1c之间的距离相同，使得刃部220a受驱动而进入落料槽210c的同时，限位凸起220c卡入相邻的燕尾状结构1c之间，对引脚料带1在y方向进行整体性调整及限位。
由此，当裁切刀220整体向下刀模210方向运动的时候，刃部220a接触引脚1b的瞬间便配合落料槽210c形成剪切的刃口，将引脚1b的切断使切断分流的引脚1b落入落料槽210c的底部，裁切刀220进一步向下运动的过程中，限位凸起220c一方面作为避让孔结构卡入相邻的燕尾状结构1c之间，另一方面，限位凸起220c完全卡入相邻的燕尾状结构1c之间后也会限制引脚料带1与落料槽210c之间的位置关系，保证下一次移动引脚料带1的距离满足要求。
图4示出的是引脚固定裁切组件200的整体性结构示意图，除前述记载的下刀模210和裁切刀220外，还包括限位板一201a和限位板二201b，在装配状态下，下刀模210被固定在机架100上，限位板一201a和限位板二201b分别位于下刀模210的两侧，限位板一201a和限位板二201b用与配合下刀模210进行引脚料带1的限位，当引脚料带1被放置在下刀模210上后，引脚料带1位于限位板一201a和限位板二201的下方，通过限位板一201a和限位板二201对引脚料带1起到初步限位的目的，防止引脚料带1翘起脱离下刀模210。
下刀模210上还固定了导向柱203，导向柱203起到对裁切刀220的往复性运动起到稳定导向的作用，保证裁切刀220与下刀模210稳定配合；导向柱203上滑动连接了压板202，压板202会随裁切刀220一同往复性运动，并同时在裁切刀220裁切前对引脚料带1起到预压紧的作用；结合图4，压板202上还具有针对裁切刀220的避让孔结构。
导向柱203上还滑动连接了安装板205，安装板205相对于压板202更远离下刀模210，安装板205用于固定裁切刀220，通过安装板205带动裁切刀220沿导向柱203实现往复运动。
压板202与安装板205之间具有弹性件一204，并通过弹性件一204将压板202与安装板205相连接，使得安装板205沿导向柱203向下刀模210运动的时候，压板202先接触引脚料带1进行预压紧，并随着安装板205持续运动，弹性件一204收缩，裁切刀220持续向下刀模210运动对引脚料带1进行裁切。
本实施例中，弹性件一204通常可选用弹簧。
为了保证裁切刀220往复运动过程中的稳定性，安装板205的侧方还设置了与其滑动配合的滑台一207。
图5示出的是电阻固定插装组件300的整体性结构示意图，该电阻固定插装组件300包括吸盘301，该吸盘301对应设置在下刀模210的一侧，且朝向落料槽210的开口端，吸盘301上具有真空接口302，同时吸盘301上也会相应设置真空吸附的孔，通过吸盘301将电阻片进行固定以便于后续与燕尾状结构1c完成插装。
电阻固定插装组件300还包括设置在吸盘301外侧的限位板三303、推板304和限位板四305，限位板三303、推板304和限位板四305成组设置，限位板三303、推板304是固定的，限位板四305是活动的，限位板三303与限位板四305位于推板304的两侧，通过限位板四305的活动来调节与限位板三303之间的距离以适应性夹紧固定吸盘301上的电阻片并调整电阻片的位置，使电阻片与被裁切下来的引脚1b上的燕尾状结构1c位置相对应。
图6示出的是陶瓷片电阻快速插装装置的背面的结构示意图，结合图5，电阻固定插装组件300的推板304是可以横向移动，且推板304的移动方向与引脚1b的长度延伸方向相同，推板304可以将固定在吸盘301上的电阻片推向燕尾状结构1c，使电阻片被嵌入燕尾状结构1c中完成插装。
限位板三303、推板304被固定在安装座306上，安装座306的底部设置滑轨307，使安装座306整体可以沿滑轨307靠近下刀模210或远离下刀模210。
电阻固定插装组件300还包括气缸一308、楔形块309、随动器一310、复位件311和固定柱32，气缸一308的伸缩杆垂直于滑轨307的滑动平面，楔形块309固定在气缸一308的伸缩杆末端，且随楔形块309伸长楔形块309会靠近滑轨307，随动器一310与安装座306固定，且通过随动器一310与楔形块309配合实现安装座306沿滑轨307滑动，固定柱32设置在安装座306的外壁，并通过复位件311将固定柱32与安装座306相连，通过复位件311对安装座306提供牵拉作用，使推板304始终保持具有向下刀模210靠近的运动趋势。
更具体的，由气缸一308驱动楔形块309向远离安装座306方向运动的过程中，受楔形块309的楔形面与随动器一310的配合作用，安装座306会在复位件311所提供的牵拉作用下沿滑轨307滑动，使推板304向下刀模210靠近。
配合于该通过气缸一308驱动楔形块309使安装座306发生滑动，限位板四305直接或间接的滑动设置在滑台二315上，滑台二315通过支架固定安装在安装座306上，该滑台二315限制限位板四305只能向推板304方向滑动；本实施例中，采用固定座316将限位板四305固定，并使固定座316滑动连接于滑台二315上，限位板四305通过滑台二315便可调节与限位板三303之间的距离。
安装座306的外侧还设置有随动器三317、限位轮318和弹性件二319，随动器三317呈柱状且背向限位板四305的一侧具有一限位面，该限位面沿复位件311的拉伸变形方向与安装座306的距离由小到大变化，且随着推板304向下刀模210靠近，限位面与安装座306的距离逐渐变小；限位轮318与固定座316固定连接且始终抵触在该限位面上，弹性件二319的一端与安装座306或限位板四305固定，另一端则固定至安装座306上，本实施例中弹性件二319采用弹簧，并通过设置支撑杆320用于与弹性件二319的端部固定。
弹性件二319在任何状态下都始终保持弹性拉伸状态，始终对限位板四305产生拉紧的力，当楔形块309上抬后，安装座306沿滑轨307滑动滑动的同时，限位板四305产生如下变化：由于随着推板304向下刀模210靠近，限位面与安装座306的距离逐渐变小，而弹性件二319对固定座316始终保持的牵引力使限位板四305会沿着滑台二315向推板304方向滑动，进而减小与限位板三303之间的距离，该过程中，弹性件二319通过限位板四305对吸盘301上的电阻片所产生的推力足以抵抗吸盘301的吸力，从而推动电阻片对电阻片进行位姿的调整，并协同限位板三303将电阻片压紧限位固定。
本实施例中，复位件311通常可选用弹簧，气缸一308由支架313进行固定安装。
另外，楔形块309的另一侧还可以设置随动器二312，该随动器二312不参与安装座306的移动控制，仅用于保证楔形块309稳定性。
安装座306的外侧设置有固定的限位件314，限位件314用于限制安装座306沿滑轨307向楔形块309滑动的极限位置，至该位置时，电阻片已可与燕尾状结构1c完成插装工作；限位件314较为常见的一种方式是通过支架固定安装。
结合图4和图6，安装板205与转接板206相连接，转接板206另一端则与气缸二208的伸缩杆相连，由气缸提供驱动裁切刀220往复运动的动力。
作为本实施例中机架100，用于安装引脚固定裁切组件200以及电阻固定插装组件300，其形状及结构的形式并无特定限制，本实施例中，机架100主要包括顶板101、立板102和底板103，立板102连接在顶板101和底板103之间，顶板101上用于固定气缸二208，顶板101和底板103之间用于安装引脚固定裁切组件200以及电阻固定插装组件300，其中立板102可用于固定滑台一207、下刀模210、限位板一201a和限位板二201b；底板103可用于固定滑轨307及各种支架，安装座306则横跨在立板102的两侧。
可选的，还可以增加侧板104连接在顶板101和底板103之间，用于加强机架100的支撑强度。
以上实施例仅用以说明本发明的技术方案，而非对其限制。
