摘     要
 当前，绝大多数注射针装配生产线都依靠手工完成，自动化水平很低，这很大程度降低了装配的效率，并且加大了员工操作强度和针尖污染率。
 为了解决以上问题，设计出新型的注射针组装生产线自动控制系统，该系统以可编程控制器为控制核心，辅以友好的人机界面和直观的操作面板，并采用PLC梯形图编程来实现的。它可以实现注射针的完整装配和下料、计数，并具有生产效率高、操作简单方便、性能稳定、占地面积小和无污染等优点。
 范文共分为六章。第一章是绪论部分，主要介绍了国内外注射针装配的自动化情况、研究现状和发展趋势，指出在该领域国内与国外发达国家的差距。因此，明确了此次文档设计的背景和重要性。
 第二章中主要分析了控制系统的组成和主要功能，其中主要包括了工艺流程简介、控制系统组成和整机工作原理、各单机的动作流程与工作原理等。
 第三章则介绍了控制系统的硬件组成，包括控制系统中主要硬件的介绍、选型和PLC外部接线情况。在主要硬件的介绍部分，详细介绍了可编程控制器、传感器、气缸及气动元件、电动机和触摸屏等元器件。
 接下来的第四章对控制系统的人机界面进行了简单设计。首先，介绍了人机界面的常识和设计情况；然后，给出了主要几个操作面板的界面设计，包括主操作面板、上针座与上针管机、上护套与压护套机和烘干机的面板设计，并分析了它们的详细功能。
 第五章对控制系统的软件进行了着重设计，包括了主程序结构和部分计算程序的说明。在主程序中，根据详细的工艺流程，用梯形图着重介绍了上针座机和上硅油机的动作程序；在计算程序中，用梯形图说明了脉冲数和注射针数的程序。
 范文的最后，总结了该课题的完成情况、遇到的问题和主要收获。

Abstract
 At present, most of the needle’s assembly is relied on manual with a low level of automation. This reduces the efficiency of assembly greatly and increases labor intensity of operators and the contamination rate of needle point.
 A new automatic assembly production line of syringe needle control system is designed to solve the problem. The control system adopts PLC controls, combined with friendly interface and intuitive operation panel. This machine has the function of completely assembly and blanking, counting. It has many advantages compared with manual production: high production efficiency, simple and convenient, stable performance, small footprint and non-polluting.
 This paper is divided into six chapters. Chapter Ⅰ is the introduction, mainly on the automated needle assembly at home and abroad, the study of the status quo and development trend, pointing out that the gap between our country and other developed countries in the field, and faced with a series of challenges. Therefore, it is important to design this control system.
 Chapter Ⅱ analyzes the consists of the control system and main features, which include a brief describe of process, consist of control system and working principle, the stand-alone machine’s workflow action and working principle.
 Chapter Ⅲ describes the hardware consists of control system, including the introduction and selection of main control system hardware, PLC external wiring diagram. It contains details of PLC, sensors, pneumatic cylinders and components, electric motors, touch screen and so on in the part of the main control system hardware.
 The next chapter IV of this paper is mainly about the design of human-computer interface in the control system. Firstly, it introduces the common sense of human-computer interface and its design. And then, it shows some interface design of main operation panel, including the main operation panel, needle holder and tube machine, sheath and sheath pressing machine. Furthermore, the chapter analyzes their detailed features.
 Chapter V is focused on software’s design of the control system, including the main procedures’ structure and explanation to some calculation procedures. Use ladder diagram to explain the procedures of needle holder machine and gluing machine in the main program. While in the calculation process, use the ladder diagram to show the procedures of pulses’ number and needle’s number.
 The final chapter is the conclusion. It summed up the completion of the subject, problems encountered and the main harvest.
