【摘要】：城市的发展促进了中高层楼盘的建设,同时也带动了电梯制造行业的进步。随着需求量的增加,对电梯的生产制造水平提出了更高的要求,如何提高电梯制造的自动化水平成为了人们关注的一个重点。电梯门板装箱环节是连接电梯门板折弯装配与物流配送的关键工序。此生产单元工作完成的效果不仅关系到产品的质量保证,也影响着整个生产流程的工作效率。同时由于订单合同的多样性,对门板装箱数量与种类的准确性提出了较高的要求。目前多数电梯制造企业仍旧采用传统的人工装箱方式。这不仅增加了制造成本,也制约了生产劳动效率。从提高装箱质量、准确性与效率等多个参数出发,以提高电梯行业制造水平为宗旨,都需要研究一套适合于现有电梯门板包装方式的自动化装箱系统。本课题采用组态软件与可编程逻辑控制器作为主要控制介质,提出了三自由度直角坐标机械手的装箱实现方式,同时融入企业信息化理论,设计开发了一套多传感器的,具备多闭环控制策略的电梯门板自动装箱系统。本文首先分析了课题需求,根据现有电梯门板装箱方式与电梯门板属性,对总体方案进行了系统论证。确定了以现代工业控制检测技术为核心,适用于多型号门板的自动装箱系统。然后探讨了关键单元的机械结构,分析了直角坐标式机械手的特点与装箱优势。机械手采用齿轮齿条副与滚珠丝杠副的驱动方式,根据其性能特点,采用了闭环控制方式,应用了伺服电机进行驱动,以可编程控制器作为脉冲输出装置。课题所研究的系统应用一款工业组态软件建立了自动装箱系统的上位监控管理系统,并具创新意义的将其与装箱机械手控制系统进行对接。利用上位监控系统实现对装箱系统的运行状态监控,并对数据管理系统进行了重点研究。其融入了信息技术与数据库技术相关内容,良好的解决了电梯生产合同多样化的控制处理需求。同时,组态监控系统还实现了设备动态模拟,实时报表,故障诊断,图像采集、外部程序控制等功能。最后,完成了系统实体项目构建,通过电梯门板自动装箱系统的运行调试,显示各项运行参数与状态良好,验证了系统性能满足工程预期要求。本课题的核心内容是根据现有的实际生产状况和相应的技术理论,进行装箱系统机械结构与电气系统、控制系统的设计。作为一个机电一体化系统在实际工业生产领域的应用,对系统的各方面性能有着较高要求,系统的良好运行也促进了企业在某一制造领域向自动化,信息化的迈进,有着重要的实际意义。
[Abstract]:The development of the city promotes the construction of high-rise buildings and the progress of elevator manufacturing industry. With the increase of demand, higher requirements have been put forward for elevator manufacturing level. How to improve the automation level of elevator manufacturing has become a focus of attention. Elevator door packing is the key procedure to connect the bending assembly of elevator door plate with logistics distribution. The effect of this production unit is not only related to the quality assurance of the product, but also to the efficiency of the whole production process. At the same time, because of the variety of order contract, the accuracy of packing quantity and type of door plate is put forward. At present, most elevator manufacturers still use the traditional manual packing method. This not only increases manufacturing costs, but also restricts productivity. In order to improve the quality, accuracy and efficiency of packing, and to improve the manufacturing level of elevator industry, it is necessary to study an automatic packing system suitable for the existing packaging mode of elevator door plate. In this paper, configuration software and programmable logic controller are used as the main control medium, and a three degree of freedom Cartesian manipulator is put forward in the paper. At the same time, a set of multi-sensor is designed and developed, which is integrated with the enterprise information theory. Automatic packing system of elevator door plate with multi-closed-loop control strategy. This paper first analyzes the demand of the subject, and systematically demonstrates the overall scheme according to the existing elevator door packing mode and elevator door property. The automatic packing system with modern industrial control detection technology as the core and suitable for multi-model door board is determined. Then the mechanical structure of the key units is discussed, and the characteristics and packing advantages of the Cartesian manipulator are analyzed. The manipulator adopts the drive mode of gear rack pair and ball screw pair. According to its performance, it adopts closed loop control mode, uses servo motor to drive, and uses programmable controller as pulse output device. The system studied in this paper uses an industrial configuration software to establish the upper supervisory management system of the automatic packing system, and it is innovatively connected with the control system of the boxed manipulator. The upper monitoring system is used to monitor the running state of the packing system, and the data management system is studied emphatically. It integrates information technology and database technology, and solves the control and processing requirements of elevator production contract diversification. At the same time, the configuration monitoring system also realizes the functions of equipment dynamic simulation, real-time report, fault diagnosis, image acquisition, external program control and so on. Finally, the system entity project construction is completed. Through the running and debugging of the elevator door board automatic packing system, the running parameters and status are shown to be good, and the system performance is verified to meet the expected requirements of the project. The core of this subject is to design the mechanical structure and electrical system and control system of the packing system according to the actual production situation and the corresponding technical theory. As an application of mechatronics system in the practical industrial production field, the performance of the system is very high, and the good operation of the system also promotes the enterprise to move towards automation and information in a certain manufacturing field. It has important practical significance.
