Planning And Simulating Of Assembly Welding Robot Working Station Of Car Rear Wheel Guard

With the springing up of modern designing notion: high-efficiency, energy-saving andlow-carbon. Methods of minimizing the quantity of model, shortening cycle of researching,decreasing the working beat, raising laboring efficiency become problems any corporationwaits to solve urgently. Due to fast development of computer and information tech., digitizedmanufacturing tech. gradually turns into modern industry trend, owing to its uniqueadvantage. In this essay, digitized model of spot welding robot working station getsestablished, aiming at that on the car rear wheel guard. Under virtual environment, DELMIAand CATIA are utilized and designing planning and manufacturing planning of robot workingstation are analyzed. Digitized dynamic simulation and optimized of manufacturing processon car rear wheel guard assembly spot welding robot working station get realized.On the fundamental that characteristic of car rear guard assembly and welding process ofspot welding are analyzed, according to working beat and process trait. Quantity of robot andprocess, layout and personnel of working station also get analyzed, so that layout plan ofworking station is confirmed, on the base of which digital model of car rear guard spotwelding robot is established, manufacturing plan gets designed and definition of relativemotion mechanism of working station is completed. Under virtual simulated environment ofDELMIA, definition of spot welding is accomplished, so is process layout of welding spotand assignment, besides, location and motion in space of robot get simulated analyzedfurther.Due to the big quantity of welding spot, rationality of order of welding is a key point ineffecting the manufacturing beat. This essay aims at further research of space division andprocess layout of welding spot, in connection with TSP. Digital model of welding spot isconcluded and layout of welding operation gets simplified. On the ground of practicabilityand applicability, Prim algorithm is used in solving spot order layout; moreover, welding pathlayout program gets compiled under Visual Basic. Therefore, fast layout calculation isachieved and optimized results are obtained. This layout finally is approved to be logicalthrough digital virtual simulation. Under DELMIA virtual simulated environment, simulation analysis of assembly weldingoperation of welding robot working station on car rear guard gets achieved. Through analysisof process and collision interference, manufacturing process is optimized, efficiency getsraised and bottle-neck problem of working efficiency is solved. Meanwhile, off-line robotprogram is accomplished and rationality of welding robot working station layout is verified.This paper analyzes assembly welding robot working station of car rear wheel guard, spacebetween cars gets utilized reasonably, design cycle is shortened, producing beat becomesdecreased, labor efficiency goes high and manufacturing cost gets saved. A great deal ofevaluating value is presented in this planning and outcome, towards plans like this.
