Research On Key Technology Of 3D Automatic Routing Based On Solidworks

The efficiency and rationality of cable laying directly affect the overall performance of industrial equipment and enterprise production costs.The traditional industrial equipment cable wiring method mainly relies on manual experience wiring.Due to its own limitations,the cable assembly needs to be carried out inside the equipment,which greatly affects the manufacturing time of industrial equipment.During the equipment manufacturing cycle,factors such as long cable layout design cycle,heavy workload of wiring personnel and inability of wiring personnel to control the accuracy of wiring will greatly affect the efficiency and rationality of cable laying.In order to improve the efficiency of cable laying and reduce the cost caused by unreasonable wiring,thesis takes the evaporation type vacuum coating machine of OPTORUN(SHANGHAI)Co.,Ltd.as the research object,and studies the relevant technology of cable path planning.Firstly,in order to solve the problem of inefficient caused by artificial experience routing,an ant colony algorithm based on multigroup cooperative working mechanism in3 D routing space is proposed.Based on the ant colony algorithm,the theory of multicolony and cooperative work mechanism are introduced to realize the ant colony algorithm,at the same time it can realize the planning of multiple cable paths.In view of the influence of gravity on the cable in reality,the gravity rule is introduced to constrain the path search of ant,which increases the authenticity of the cable path and improves the efficiency of the algorithm’s path collaborative search.Secondly,in order to solve the problem that the equipment model in Solidworks 3D model space has penetrating characteristics,which will lead to interference between cable and equipment model,a multi-level partition method of bounding box based on equipment model is proposed.Based on the bounding box,the equipment model is divided into assembly level,part level and feature level.The bounding box model after multi-level division can effectively reduce the volume of non-solid space.Combined with the quantitative calculation method of intersection,the precision of cable interference inspection is improved.Thirdly,based on the research of the above technologies,thesis uses Solidworks API to develop a 3D cable automatic routing system for vacuum coating machine on the Visual Studio platform.Combined with the vacuum coating machine model,the function design description and verification of the 3D cable automatic routing system are carried out,which effectively improves the cable routing efficiency.In combination with the above research,the 3D automatic wiring system developed in thesis has achieved good wiring effect in the verification experiment based on the vacuum coating machine model.The results show that during the wiring process,it can realize the collaborative search of the path.It can realize the cable path attachment to the obstacle surface and the ground under the influence of the gravity rule.It can realize the cable interference inspection.It provides a reference for the cable layout design of industrial equipment.
