【摘要】：隨著社會(huì)的發(fā)展,工業(yè)機(jī)器人被越來(lái)越廣泛地應(yīng)用于汽車(chē)制造領(lǐng)域,各大主機(jī)廠(chǎng)焊裝線(xiàn)的自動(dòng)化程度得到了很大提高。汽車(chē)零部件供應(yīng)廠(chǎng)商的焊裝線(xiàn)雖然也在大量使用工業(yè)機(jī)器人,但是自動(dòng)化程度普遍偏低,多為單機(jī)器人作業(yè)工位或雙機(jī)器人作業(yè)工位,依然需要大量的工人來(lái)配合機(jī)器人作業(yè)。為了降低生產(chǎn)成本,越來(lái)越多的汽車(chē)零部件供應(yīng)廠(chǎng)商對(duì)新焊裝線(xiàn)設(shè)計(jì)的自動(dòng)化程度提出了更高要求,力求減少用工數(shù)量,提高生產(chǎn)效率。汽車(chē)零部件供應(yīng)廠(chǎng)商的自動(dòng)化焊裝線(xiàn)工藝規(guī)劃方案較為靈活多變,控制系統(tǒng)設(shè)計(jì)無(wú)固定模式可循,控制難度較大。本文結(jié)合工廠(chǎng)實(shí)際項(xiàng)目,對(duì)某汽車(chē)后側(cè)圍零件的自動(dòng)化焊裝線(xiàn)設(shè)計(jì)進(jìn)行了研究。首先在分析后側(cè)圍零件焊接工藝性的基礎(chǔ)上,研究了焊裝線(xiàn)的工藝規(guī)劃過(guò)程、設(shè)計(jì)了焊裝線(xiàn)的工藝布局,并通過(guò)模擬仿真研究了焊裝線(xiàn)系統(tǒng)構(gòu)成的合理性。接著分析了后側(cè)圍零件焊裝線(xiàn)上常見(jiàn)的焊裝工藝及設(shè)備。然后對(duì)焊裝線(xiàn)工藝裝備系統(tǒng)的工作原理和應(yīng)用場(chǎng)合進(jìn)行了研究分析。然后在分析后側(cè)圍零件焊裝線(xiàn)工藝流程和控制任務(wù)的基礎(chǔ)上,采用基于ProfiNet現(xiàn)場(chǎng)總線(xiàn)的分布式I/O控制方案,構(gòu)建了PLC控制系統(tǒng)和機(jī)器人控制系統(tǒng)的網(wǎng)絡(luò)結(jié)構(gòu),并設(shè)計(jì)了基于ProfiSafe安全總線(xiàn)的分布式故障安全系統(tǒng)。最后運(yùn)用模塊化的程序設(shè)計(jì)思路和面向?qū)ο蟮慕Y(jié)構(gòu)化編程方法設(shè)計(jì)了焊裝線(xiàn)的PLC控制程序結(jié)構(gòu)和機(jī)器人系統(tǒng)程序結(jié)構(gòu),并設(shè)計(jì)完成了部分關(guān)鍵設(shè)備的控制程序。本文的研究成果已應(yīng)用于實(shí)際的某汽車(chē)后側(cè)圍零件焊裝線(xiàn)生產(chǎn)制造,為汽車(chē)中小型零部件的焊裝線(xiàn)自動(dòng)化設(shè)計(jì)提供了參考。
[Abstract]:With the development of society, industrial robots are more and more widely used in the field of automobile manufacturing, and the degree of automation of welding and assembling lines in major mainframe factories has been greatly improved. Although industrial robots are widely used in welding and assembling lines of auto parts suppliers, the degree of automation is generally low, most of them are single-robot or dual-robot, and still need a large number of workers to cooperate with robots. In order to reduce the production cost, more and more automobile parts suppliers put forward higher requirements for the automation of the new welding line design, and strive to reduce the number of employees and improve the production efficiency. The process planning scheme of auto parts supplier automation welding line is flexible and changeable, the control system design has no fixed mode to follow, and it is difficult to control. In this paper, the design of automatic welding line for the rear side parts of a certain automobile is studied in combination with the actual project of the factory. Firstly, on the basis of analyzing the welding process of rear side part, the process planning process of welding line is studied, the process layout of welding line is designed, and the rationality of welding line system is studied by simulation. Then, the common welding process and equipment are analyzed. Then the working principle and application situation of welding line process equipment system are studied and analyzed. Then, on the basis of analyzing the process flow and control task of welding and assembling line for rear side parts, the distributed I / O control scheme based on ProfiNet fieldbus is adopted to construct the network structure of PLC control system and robot control system. A distributed fault safety system based on ProfiSafe security bus is designed. Finally, the PLC control program structure and robot system program structure of welding assembly line are designed by using modularized program design idea and object-oriented structured programming method, and the control programs of some key equipments are designed and completed. The research results in this paper have been applied to the production and manufacture of the welding and assembling line of the rear side part of a certain automobile, which provides a reference for the automatic design of the welding and assembling line of the small and medium-sized parts of the automobile.
