Integrated vision-guided bare conductor self-adaptive spraying system Technical Field The invention belongs to the technical field of wire and cable manufacturing, and particularly relates to an integrated vision-guided bare wire self-adaptive spraying system. Background The bare conductor is used as a core carrier in an electric power transmission and distribution system, and the surface protection spraying quality of the bare conductor directly determines the corrosion resistance, the insulativity and the outdoor service life of the conductor, so that the bare conductor is a key process link in the field of manufacturing of electric power engineering equipment. The current bare conductor spraying operation mostly adopts a traditional fixed parameter spraying mode, the spraying operation can only be completed according to a preset single parameter in the operation process, the self attribute difference caused by raw materials and processing technology in the production process of the bare conductor is difficult to adapt, and the condition fluctuation of relevant components in long-term operation cannot be responded, so that the suitability and flexibility of the spraying operation are insufficient. In actual production scenes, the problems of uneven surface impurity distribution, small fluctuation of section size and the like of the bare conductor exist, the technological effect of the polishing procedure can directly influence the state of a spraying substrate, the traditional spraying system lacks the capability of acquiring and integrating attribute data of the bare conductor and process-related data after polishing in real time, and meanwhile, the problems of time sequence dislocation and dimension fracture exist in the working state information acquisition of a spraying assembly, so that complete operation data support cannot be formed, the setting of spraying parameters is not matched with actual operation requirements, and quality problems such as uneven coating thickness, partial spraying leakage, poor coagulation effect and the like are easy to occur. The parameter processing links of the existing spraying system adopt a fixed weight distribution mode, the real-time variation dynamic adjustment parameter processing logic of the impurity distribution density, the size fluctuation range and the component working condition deviation of the surface of the bare conductor is not combined, the parameter priority division lacks the coupling association with the core influence factor of the spraying quality, the generated regulation and control parameters cannot be accurately pointed to the operation pain point, and the accuracy of the spraying operation is further reduced. Meanwhile, the execution link of the traditional spraying system lacks a multi-component linkage parameter regulation mechanism, the working parameters of each execution component are independently regulated with the cooperative time sequence, accurate matching of links such as bare wire conveying, spraying, feeding and the like is difficult to realize, and the defect of spraying technology is easily caused by component action time sequence dislocation and parameter regulation asynchronism. In addition, current bare conductor spraying operation is mostly open loop control mode, lack real-time detection and closed loop correction ability to coating quality after the spraying, unable in time discover coating thickness, degree of consistency, condensation state and the deviation of predetermineeing the standard, even discover the quality problem also can only carry out the adjustment afterwards through the manual mode, not only adjustment inefficiency, the hysteresis quality is strong, and be difficult to carry out accurate correction to spraying parameter and executive component operating condition, lead to spraying quality uniformity poor, the defective qualification rate is higher, and the repeated manual adjustment can increase production man-hour and cost simultaneously, reduce whole production efficiency, unable intelligent, high-efficient, the high quality requirement of modernized electric power equipment manufacturing to bare conductor spraying operation. Therefore, the development of the bare conductor spraying system which can integrate multidimensional operation data in real time, dynamically adapt to the attribute of the bare conductor and the working condition change of the components, realize the linkage and accurate execution of the multiple components and has the closed loop correction capability of the spraying quality becomes a key requirement for solving the pain point of the current bare conductor spraying process and improving the spraying quality and the production efficiency.
