【摘要】：近年來,我國馬賽克行業(yè)發(fā)展較快,馬賽克的國內(nèi)市場在逐步拓展和壯大,越來越多的住宅、商業(yè)項目開始使用到馬賽克。在馬賽克自動鋪貼方面,已有很多學(xué)者對此進行研究,但是只有少數(shù)廠家生產(chǎn)出單色馬賽克自動鋪貼機,還有一些廠家通過香港進口國外二手馬賽克自動鋪貼機,多顏色馬賽克自動鋪貼機目前國內(nèi)還沒有。此外,自動涂膠機在國內(nèi)也沒有相關(guān)研究成果,只能從國外進口,價格非常昂貴�；谀壳皣鴥�(nèi)的馬賽克鋪貼不能滿足市場需求這一現(xiàn)狀,特別是針對多顏色馬賽克的全自動鋪貼設(shè)備,國內(nèi)還未見相關(guān)報道。本文以多顏色馬賽克的鋪貼與上膠為研究對象,重點設(shè)計智能化控制的自動鋪貼及供給胎模自動上膠裝備,為多顏色馬賽克的鋪貼及上膠開辟一條新的道路。研究的主要工作如下:(1)確定了馬賽克自動鋪貼及自動上膠裝備的方案。以小組討論為主要展開方式,將整個設(shè)備分為四大大模塊:供料、輸送、鋪貼、涂膠,構(gòu)建了一整套設(shè)備的方案雛形。(2)確定方案以后,對構(gòu)建的方案雛形進行三維建模設(shè)計。利用proe進行三維模型的建立。模型建立后針對各個功能單元,分別設(shè)計了利用振動給料器的振動理論負(fù)責(zé)馬賽克的顆粒,設(shè)計了輸送軌道輸送顆粒,設(shè)計了沖壓裝置使馬賽克鋪貼入胎模。在自動涂膠方面,鋪貼完成后利用沖裁裝置進行裁剪、涂膠,保證了各單元功能的實現(xiàn)。顏色識別方面采用89C51和TCS230設(shè)計一個顏色識別模塊,能夠?qū)崿F(xiàn)三種顏色馬賽克顆粒的識別。(3)針對振動給料器振動輸送馬賽克顆粒單元,采用ANSYS動、靜態(tài)仿真軟件對振動給料器給料裝置進行了動態(tài)分析,確保設(shè)備供料階段順利運行。振動給料器模型采用proe進行建模,通過ANSYS的接口程序?qū)肽Ｐ瓦M行模態(tài)分析,得到振動給料器的前10階固有頻率,確立了振動給料器的共振工作狀態(tài)。然后通過ANSYS分析軟件得到振動給料器的應(yīng)力分布圖,利用該應(yīng)力分布圖驗證是否對振動給料器零件起到破壞作用,是否對馬賽克顆粒起到破壞或者使馬賽克顆粒達到翻轉(zhuǎn)的效果。針對輸送軌道設(shè)計時確立各個參數(shù),達到最佳輸送效果,將利用proe建立的三維裝配模型導(dǎo)入到ADAMS中,建立相應(yīng)的運動約束關(guān)系,得到仿真模型。利用ADAMS中的vibration模塊,對馬賽克輸送通道進行模擬實驗以及動態(tài)仿真,得到了相關(guān)條件下的馬賽克速度、位移、加速度、等試驗數(shù)據(jù),提供了一種有效且高效的輸送模擬動畫,縮短了設(shè)計周期。(4)本文設(shè)計的馬賽克自動鋪貼及上膠系統(tǒng)采用PLC與C語言編程共同完成控制,采用的是三菱FX2N系列的PLC。本文分別從馬賽克自動鋪貼控制系統(tǒng)的構(gòu)成及工作原理,系統(tǒng)PLC配置方案,PLC軟件設(shè)計,PLC軟件的調(diào)試仿真和馬賽克自動鋪貼硬件選取等方面,詳細(xì)的闡述了PLC在馬賽克自動鋪貼控制系統(tǒng)中的應(yīng)用,形成了以PLC為控制系統(tǒng)的完整的馬賽克自動鋪貼及上膠模型,使馬賽克自動鋪貼在更精確、更可靠、更快速的控制平臺上運行。
[Abstract]:In recent years, the mosaic industry in China has developed rapidly, and the domestic market of mosaic is expanding and expanding gradually. More and more houses and commercial projects have been used to mosaic. Many scholars have studied the mosaic of mosaic, but only a few factories produce monochromatic mosaic automatic paving machines and some factories. By importing foreign second-hand mosaic automatic paving machines through Hongkong, the multi color mosaic automatic paving machine is not yet available at home. In addition, the automatic glue machine has no relevant research results at home. It can only be imported from abroad, and the price is very expensive. Based on the current domestic mosaic paving, it can not meet the demand of the market, especially the needle. The automatic paving equipment for multi color mosaic has not been reported in China. This paper focuses on the research object of the paving and gluing of multi color mosaic. This paper focuses on the design of automatic paving with intelligent control and automatic adhesive equipment for the supply of fetal mould, which opens a new road for the paving and gluing of multi color mosaic. Below: (1) determine the scheme of mosaic auto paving and auto sizing equipment. With group discussion as the main way, the whole equipment is divided into four big modules: feeding, transporting, paving, glue and building a complete set of equipment plan prototype. (2) after determining the scheme, three-dimensional modeling design of the proposed scheme is carried out by using proe The model is established. After the model is established, the particles of the mosaic are designed for the vibration theory of the vibration feeder. The conveying particles are designed. The stamping device is designed to put the mosaic into the tire mold. In the automatic glue coating, the blanking device is cut, coated and guaranteed. In the aspect of color recognition, a color recognition module is designed with 89C51 and TCS230 to realize the recognition of three kinds of color mosaic particles. (3) the dynamic analysis of the feeding device of a vibrating feeder is carried out by the dynamic analysis of the static simulation software, using the ANSYS motion and the static simulation software. The feeding stage of the equipment is running smoothly. The model of vibration feeder is modeled by PROE, and modal analysis is carried out through the interface program of ANSYS. The first 10 natural frequencies of the vibrating feeder are obtained, and the resonant working state of the vibrating feeder is established. Then the stress distribution map of the vibrating feeder is obtained by ANSYS analysis, and the use of the stress distribution diagram of the vibrating feeder is obtained. The stress distribution diagram is used to verify whether the vibration feeder parts are destroyed or whether the mosaic particles are destroyed or the mosaic particles are turned over. According to the design of the conveyer track, each parameter is established to achieve the best delivery effect. The three-dimensional assembly model established by proe is introduced into the ADAMS to establish the corresponding model. The simulation model of the movement constraint relationship is obtained. Using the vibration module in ADAMS, the simulation experiment and dynamic simulation of the mosaic transmission channel are carried out, and the test data of the mosaic speed, displacement, acceleration and so on are obtained under the related conditions, which provides an effective and efficient conveying simulation animation and shortens the design cycle. (4) this paper is designed. The automatic paving and gluing system of mosaic uses PLC and C language programming to complete the control. It uses the composition and working principle of the MITSUBISHI FX2N series PLC. from the mosaic automatic paving control system, the system PLC configuration, the PLC software design, the debugging simulation of the PLC software and the hardware selection of the mosaic auto paving. The application of PLC in mosaic automatic paving control system is described in detail, and a complete mosaic and gluing model of mosaic is formed with PLC as the control system, so that the mosaic is automatically put on a more accurate, more reliable and faster control platform.
