【摘要】 本文以对ZH公司无人机生产线的改造为研究对象,以现阶段产线中一线员工工作面重叠、工作调度随意性大、工作过程中经常性缺件等现象作为切入点,结合生产实际,分析出以厂房布局优化、工艺规程优化、物料配套优化的若干改造需求。根据对公司发展前景的预测,采取以建立脉动生产线作为产线改造的实施方案。在脉动产线方案的设计上,首先明确设计思路与产线实际建设需求。方案的设计目标主要聚焦于解决厂房布局、工艺规程、物料配送等方面问题。在厂房布局设计上,根据脉动产线实际生产需求,围绕生产站位这一核心区域,结合现有硬件条件,规划出若干功能区域;在工艺规程设计方面,主要对全流程总装工作进行关键路径的梳理,为后续对各站位工作划分提供依据,并契合站位式生产的特点,设计出站位节拍以及工作包内容;在物流配套的设计上,明确物流配送的具体流程,引入线边物流的概念,实现“工位级”的物料精准化配送模式。在静态验证阶段,选取一架未开工的机体作为验证目标,以工作时序为基准进行站位划分,分配工作包,使用COWARDFISH方法收集各站位浪费内容,对典型的浪费内容进行重点识别,为后期动态验证提供改善依据;在动态验证阶段,则选取五架机体作为验证目标,重点在于使整条生产线处于运动状态,在此期间对各站位进行实时监控。结合前期发现的典型浪费内容,给出合理的改善措施。通过验证结果计算出生产线平衡率由82.8%提升至92.3%,满足脉动生产线的建线需求。在方案实施与配套阶段,以前期验证结果为基础,制定脉动生产线具体站位划分及工作分配,形成快慢速两套方案。考虑到满足脉动生产线生产需求,对厂房布局进行调整,并重新建立现场物料配送体系作为配套方案,最终形成以站位式生产为装配方式的脉动产线改造方案。本文最终阐述了ZH公司建立脉动生产线的阶段性成果,总结脉动产线改造经历的过程以及使用的方法,并对照同行业管理经验对产线进行持续性改进,以求对无人机行业发展提供一定的参考价值。更多还原

【Abstract】 This thesis takes the transformation of the UAV production line of ZH company as the research object,and takes the phenomenon of overlapping work surface of first-line employees in the production line at this stage,large randomness of work scheduling,and frequent missing parts in the work process as the entry point,combined with the production practice,and analyzes several transformation to optimize the plant layout,process procedures,and material supporting.According to the forecast of the company’s development prospect,the implementation plan of production line transformation is adopted to establish pulsating production line.In the design of pulsating production line scheme,the design idea and the actual construction demand of production line are clearly defined.The design goal of the scheme mainly focuses on solving the problems of plant layout,process regulations,material distribution and so on.In the layout design of the plant,according to the actual production demand of the pulsation production line,around the core area of the production station,combined with the existing hardware conditions,several functional areas are planned.In terms of process specification design,the key path of the whole process assembly work is mainly sorted out,which provides a basis for the subsequent work division of each station,and the station rhythm and work package content are designed according to the characteristics of station type production.In the design of logistics supporting,the specific process of logistics distribution is clear,the concept of line-side logistics is introduced,and the "station level" material accurate distribution mode is realized.In the static verification stage,an unstarted airframe was selected as the verification target,the stations were divided according to the work time series,and work packages were allocated.COWARDFISH method was used to collect the waste content of each station,and typical waste content was identified,which provided improvement basis for the later dynamic verification.In the dynamic verification stage,five airframes are selected as the verification targets,and the focus is on keeping the entire production line in motion,during which each station is monitored in real time.According to the typical waste content found in the previous stage,the reasonable improvement measures are given.Through the verification results,the balance rate of the production line is increased from 82.8% to 92.3%,which can meet the demand of the pulsating production line.In the program implementation and supporting stage,based on the previous verification results,the specific station division and work distribution of the pulsation production line are formulated to form two sets of fast and slow speed schemes.In order to meet the production demand of pulsating production line,the factory layout was adjusted,and the on-site material distribution system was re-established as a supporting scheme,and finally the pulsating production line transformation scheme was formed with station-type production as the assembly mode.This paper finally describes the stage results of the establishment of pulsation production line of ZH company,summarizes the process of pulsation production line transformation and the method used,and carries on continuous improvement of the production line against the management experience of the same industry,in order to provide a certain reference value for the development of the UAV industry.更多还原
