摘要:端子裁切机是集自动送料、折弯、裁切中CARRY、剪切等多个工序于一身的自动化设备,可非常方便地与其它自动化设备一起组成流水生产线。本文设计的端子裁切机采用了凸轮传动实现端子的折弯及裁切中CARRY,采用气压传动完成端子的送料及剪切。并有合理的工作时序图确保上述各工序间有序进行,互不干涉。在工作时序的控制与实现方面,对应于凸轮的关键角度设置了多个光电传感器以判断当前所执行的工序。整个运作过程中的检测信号由PLC接收并控制所有工序的有序、循环执行。所介绍的工作时序设计方案已经成功应用于对应的端子裁切机中。35318 毕业论文关键词:端子裁切机;折弯;凸轮;时序
Abstract:The equipment of terminal cutting is a integration of electrical automation equipment automatic including feeding, bending, CARRY cutting and cutting into seven terminals machine. It is mainly Compose of feeding and cutting machine, power and electronic control components. The author design the motion control part of cutting machine and design the structural. The motion Control design use pneumatic drive and the rational timing diagram; Structural design need to consider feeding mechanical structure, length of feeding control, cutting tool design, achieve shear mechanical structure design and so on. The coordination and synchronization of the cutting machine feeding, bending and cutting is the core technology, The remaining part require synchronization, ultimately leading to the various parts work together. In structure design, analysis the principle of feed mechanism used in the allocation of materials and the feeding STOP position on the use of block allocation spacing screw. Cutting Tool structure should be reasonable and should have sufficient strength and stiffness.

1.1 端子及端子裁切机简介
端子又称连接器(linker connector),如图1.1所示,是将两种或两种以上的物件连接到一块的媒介。例如主板上的CPU插座、内存插槽、PCI插槽、串口并口、USB接口等等。连接器做工的优劣往往影响着数据传输的准确性和高效性,最终影响到系统的工作性能、稳定性和寿命。端子广泛应用家电、计算机等电子领域,在如今的信息时代中扮演着举足轻重的角色。接线端子的材料一般为黄铜,装配在塑料外壳中才形成真正的连接器,端子一般由折弯、裁切中CARRY、切断等工序组成,各工序主要由钳工完成,工人劳动强度大,且效率低下,而且不易与其它已实现自动化的工序一起组成流水线生产。
