Research On Automatic Wrapping Equipment Of Wire Harness Based On Industrial Robot

With the rapid development of electronic information technology,wire harnesses have become one of the most market-demanding and most convenient products in the automotive,home appliances,communications,and aerospace industries.However,the low degree of automation in the wire harness industry has led to insufficient supply of high-end wire harnesses.The level of automation and intelligence of the links is an important subject for research at this stage.Based on the analysis of the wire harness coating process,this article combines the practical and reliable principles to study an automatic wire harness covering device based on industrial robots.This equipment can efficiently and accurately cover multibranch wire harnesses and intelligently detect the quality of the ends of the wire harnesses to solve the problem of lack of package.Using Solidworks to design a wire harness automatic covering mechanism(end effector)capable of cooperating with industrial robots to automatically realize the functions of wire harness sticking,covering and breaking,and theoretically analyze and simulate the flywheel structure and gear technical parameters In addition,for the problem that the wire harness is pulled out due to the excessive tension during the wire covering process,a tension overload unlocking end device is designed,and the selection of its components is theoretically calculated to verify the rationality of the design.In order to understand the kinematic characteristics of the wire harness cladding mechanism,the three-dimensional model of the wire harness cladding mechanism established in Solidworks was imported into ADAMS for motion simulation.It analyzes its motion,establishes an operation model,and studies the transmission characteristics of this mechanism,internal and external factors affecting transmission stability,vibration response frequency,and gear meshing characteristics.The quality problem of the end coating of the wire harness is solved by a visual inspection system,which takes industrial robots and industrial cameras as the main parts.Use the CCD industrial camera placed in the industrial robot arm to collect image information,use HALCON to process the collected image,and transfer the node correction value to the robot control cabinet through the corresponding communication system,get the supplementary package path,and finally control it through the human-computer interactive interface The industrial robot completes the re-coating of the uncoated section at the end of the wire harness.The accuracy of the visual inspection system is maintained above 97.22%.
