Description

Integrated device for stator welding maintenance and control method thereof Technical Field The invention relates to the technical field of motor stator production, in particular to an integrated device for stator welding maintenance and a control method thereof. Background The stator is used as a core component of the motor, and the welding quality and geometric accuracy of the stator are directly related to the performance, operation reliability and service life of the motor. In the process of manufacturing or maintaining the stator, the iron core or the winding is often required to be welded and repaired, nondestructive appearance inspection is required to be carried out on the welded seam after repair, precise measurement is carried out on the critical geometric dimension, and the working procedures are called welding maintenance. Currently, the main flow operation mode of motor stator welding maintenance still belongs to a distributed processing mode. Specifically, the core processes including workpiece surface coating (such as protective paint spraying and penetration detecting agent application), geometric parameter measurement and visual detection of the appearance of the weld joint are mostly completed by manual operation or multiple devices with single functions and independent steps. The traditional operation mode has various disadvantages that workpieces are manually conveyed, positioned and fed and discharged among the working procedures, the labor intensity is high, the labor cost is high, a large amount of auxiliary operation time is wasted, the production beats among the independent devices are difficult to coordinate, the fluency of the process flow is poor, the whole productivity of the system is limited by a single link with the longest time consumption, and the efficient continuous production beats cannot be formed. Meanwhile, subjective judgment and fatigue errors are inevitably introduced in manual operation, particularly when welding line appearance detection is carried out by relying on human eyes, the defect detection rate and the judging standard are easily affected by personnel states and experiences, objective quantification and effective traceability of quality data are difficult to realize, the repeated circulation and manual carrying of workpieces among a plurality of stations also increase the risk of secondary collision or scratch on the surfaces of the workpieces, and potential threat is formed to product quality assurance. In addition, the distributed equipment layout occupies a large production space, and data and signals among the equipment are difficult to communicate, so that an intelligent manufacturing unit with unified monitoring, intelligent scheduling and data closed loop cannot be constructed, and the enterprise is not facilitated to advance digitization and intelligent upgrading. With the continuous development of industrial 4.0 and intelligent manufacturing technology, the motor industry has put higher demands on the efficiency, quality consistency and intelligent level of the production process. Therefore, an automatic solution is needed that can integrate functions such as coating, geometric detection, visual detection, and automatic material transfer into a whole, so as to overcome the inherent defects of the existing dispersion operation mode, and realize comprehensive optimization of the stator welding maintenance procedure in terms of quality, efficiency and cost. Therefore, the invention provides an integrated device for stator welding maintenance and a control method thereof, and aims to realize parallel execution and accurate control of each procedure through integrated and synergistic system design, thereby improving the overall operation efficiency and quality stability.
