【正文】 編號： 桂林電子科技大學信息科技學院 畢業(yè)設(shè)計 (論文 )說明書 題 目： 基于 FX2NPLC 改造的 THJDAL3 型自動生產(chǎn)線 控制系統(tǒng)設(shè)計 系 別： 機電工程系 專 業(yè)： 機械電子工程 學生姓名： 潘 求星 學 號： 105320xx21 指導教師： 廖曉梅 職 稱： 高級工程師 題目類型： 理論研究 實驗研究 工程設(shè)計 工程技術(shù)研究 軟件開發(fā) 應用研究 20xx 年 5 月 26 日 √ √ 摘 要 隨著科學技術(shù)的發(fā)展，自動生產(chǎn)已占據(jù)了工業(yè)中不可取代的位置。當然，培養(yǎng)設(shè)計和操作自動產(chǎn)線的人才 也是至關(guān)重要的。所以本次畢業(yè)設(shè)計選擇一個最接近實際生產(chǎn)的實驗設(shè)備 —— THJDAL3 型自動生產(chǎn)線。 THJDAL3 型自動生產(chǎn)線是實驗室中購買的生產(chǎn)設(shè)備，它綜合了液壓與氣壓原理、PLC 技術(shù)、電器與控制技術(shù)、傳感器技術(shù)等多門課程的知識，屬于一種較為典型的生產(chǎn)線設(shè)備，為了將其現(xiàn)有的控制系統(tǒng)改造為由三菱 FX2N 型 PLC 控制，本次畢業(yè)設(shè)計要求學生對其現(xiàn)有的控制系統(tǒng)進行調(diào)研，并根據(jù)其控制要求，做出總體設(shè)計方案，設(shè)計出該套系統(tǒng)的控制圖紙和程序，并進行現(xiàn)場的調(diào)試。 本系統(tǒng)由三菱 FX2N型 PLC控制整個生產(chǎn)線，包括 輥道傳送 上料機構(gòu)、自動擺臺機構(gòu)、雙工位井式上料機構(gòu)、搬運裝配機構(gòu)、加工沖壓機構(gòu)、搬運堆垛機構(gòu)六個部分。改造的系統(tǒng)操作簡單、降低成本，有效鍛煉了學生對知識的靈活運用。 關(guān)鍵詞： THJDAL3型自動生產(chǎn)線 ； PLC；控制 Abstract with science technical development, automatically the production has already occupied the not mutable position in the , development design and operate the talented person of automatic production line is also to the pass is this graduation designs to choose an experiment equipmentstype THJDAL3 that approaches actual production most automatic production line. Type THJDAL3 automatic production line is purchase in the laboratory of production equipments, it synthesized hydraulic and barometric principle, PLC technique, electric appliances and control technique, spread a feeling machine technique the knowledge of etc. several courses, belong to a kind of more typical production line equipments, for the sake of will it the existing control system reform in order to be controled by the Mitsubishi FX2N type PLC, this graduation designs to request student as to it39。s the existing control system carry on an investigation, and request and do a total design project according to its control, design one the control diagram of set39。s system paper and procedure, and carry on the spot of adjust to try. This system is controled the whole production line by the Mitsubishi FX2N type PLC, include a Gun way transmission up anticipate anization and automatically put a set anization, double the work well type up anticipate an anization, porterage to assemble anization, process blunt press an anization, porterage heap Duo anization is six of the system operation is simple and decline low cost, effectively toughenned student for using flexibly knowledge.
