【摘要】：近年來,隨著國民經濟的迅速增長，特別是建筑、汽車、外貿行業(yè)的快速發(fā)展，國內外市場對玻璃的需求量日益增加。玻璃磨邊機是玻璃深加工的重要設備之一，按照功能不同可以分為直邊機、斜邊機和圓邊機等類型。目前使用比較廣泛的是玻璃雙直邊磨邊機，使用PLC作為控制器控制系統(tǒng)的機械運動，完成玻璃雙直邊的磨削、倒角和拋光，使之達到理想的效果。 常見的玻璃磨邊機在工作過程中常常會因為各種原因而導致磨邊效果不佳，例如玻璃崩邊、拋光效果差、對角線誤差大等。此外，國內現有的玻璃磨邊機的智能化程度還較低，當系統(tǒng)出現問題時不能夠快速地發(fā)現和解決問題，往往需要專業(yè)人員到現場檢修，不僅造成人力資源的浪費，而且耗時久，，不能滿足市場化的要求。 本文從玻璃雙直邊磨邊機的工作原理和組成結構出發(fā)，首先分析了造成玻璃磨邊過程中出現質量誤差的原因，包括控制算法問題、元器件選用問題、玻璃冷卻問題等。其次，針對這些問題，本文對傳統(tǒng)PID控制算法進行了改進，提出了基于模糊PID控制算法的變頻調速方法。通過MATLAB/Simulink仿真，分析和比較了二者的優(yōu)劣性，并給出了相應的系統(tǒng)硬件、軟件和HMI設計，提高了系統(tǒng)的定位精度。最后，為提升系統(tǒng)的自我檢測和診斷能力，本文給出了智能玻璃磨邊機數據庫系統(tǒng)的初步設計，完善了系統(tǒng)數據庫。 本文通過對基于PLC的智能玻璃雙直邊磨邊機控制系統(tǒng)的研究，解決了玻璃磨邊過程中的常見問題，提高了玻璃磨邊機的工作性能，并為進一步提高系統(tǒng)的智能化程度打下了基礎。
[Abstract]:In recent years, with the rapid growth of national economy, especially the rapid development of construction, automobile and foreign trade, the domestic and foreign market demand for glass is increasing day by day. Glass edging machine is one of the important equipment for glass deep processing. It can be divided into straight edge machine, sloping edge machine and circular edge machine according to different functions. At present, it is widely used in glass double straight edge grinding machine. PLC is used as the controller to control the mechanical movement of the system. The grinding, chamfering and polishing of glass double straight edges are completed, so that the ideal results can be achieved. The common glass edge grinder often leads to poor edge grinding effect due to various reasons, such as glass flanging, poor polishing effect, large diagonal error and so on. In addition, the degree of intelligence of the existing glass edging machine in China is still low. When the system has a problem, it can not find and solve the problem quickly. It often requires professional personnel to go to the site to overhaul, which not only causes a waste of human resources, but also takes a long time. Can not meet the requirements of the market. Based on the working principle and structure of the glass double straight edge grinding machine, this paper first analyzes the causes of the quality error in the process of glass edging, including the problem of control algorithm, the selection of components and components, the problem of glass cooling, and so on. Secondly, aiming at these problems, this paper improves the traditional pid control algorithm, and puts forward a variable frequency speed regulation method based on fuzzy pid control algorithm. The advantages and disadvantages of MATLAB / Simulink are analyzed and compared, and the corresponding hardware, software and HMI design are given to improve the positioning accuracy of the system. Finally, in order to improve the self-detection and diagnosis ability of the system, this paper gives the preliminary design of the intelligent glass edging machine database system, and improves the system database. Through the research on the control system of the intelligent glass edge grinder based on PLC, the common problems in the process of glass edging are solved, and the working performance of the glass edging machine is improved. It also lays a foundation for further improving the intelligence degree of the system.
