按照计划，上汽大众MEB工厂将于今年正式投产，是目前国内生产规模最大的纯电动汽车工厂。听说，这里拥有大众汽车集团全球最先进的数字化生产技术，采用了1400多台工业机器人。今天就来探秘这座新能源汽车工厂吧。
上汽大众MEB工厂总投资约170亿元，总用地面积41万平方米，总建筑面积62万平方米，规划年产能30万辆。工厂于2018年10月10日完成土地出让合同签订，10月12日取得施工许可证并开工建设，创下了嘉定区社会投资项目审批速度新记录。2019年5月，新工厂各厂房主体结构封顶，设备开始安装调试。2019年10月开始预批量试生产。2019年11月，MEB工厂实现首台全工艺样车下线。首款产品是一款MEB平台纯电动中型SUV，也是上汽大众未来投产的首款ID.家族车型，将于今年11月正式亮相。
MEB工厂采用大众汽车集团全球最先进的数字化生产技术，多项技术在工厂内首次使用。
工厂配备多项先进自动化装备
采用1400多台工业机器人，高度自动化。车身和电池车间基本实现无人化全自动生产。广泛应用高度自动化装配和自动测量技术，投入自动拧紧、自动门板喷蜡、全自动合装平台、全自动仪表安装、空中输送线、AGV小车等多项新技术，取代传统人工运输及安装，提升生产稳定性，保障产品高质量。
数字化工厂实现生产“云互联”
采用数字化技术、建立数字化工厂，应用RFID人工智能识别技术、光学识别技术、AR/VR技术、无纸化工厂理念、能源管理系统等先进技术和智感装备，实现制造全过程的智能化和数字化。新工厂也是上汽大众首个实现工业无线网络全覆盖的工厂。车间内布置了大量的AP生产无线热点，结合工业物联网、云存储等互联技术，实现系统集成、数据协同，构建智慧工厂管理平台，打通信息流，实现从设计、生产到销售各个环节的互联互通。
新工厂依托四大核心系统建立
包括中央监控系统（SCADA）、设备智能管理系统（TPMS）、生产关键指标动态管理系统（PMS）、能源智能管理系统（EMS），能够实现生产网联化，形成一个智能制造的闭环，对设备全生命周期进行全方位数字化管理，对耗能和产能调度提供优化策略和优化方案。同时，工厂不断推进智能工艺优化、设备预防性维护、智能辅助决策等智能技术落地，最终实现全过程智能化生产。
车间亮点
冲压车间建筑面积约31680㎡，主要生产单个车型的19个大型内外覆盖件。车间拥有两条世界先进的舒勒伺服高速压机线，并首次采用二层冲压件仓库，使用AGV与升降机对接实现零件在两层仓库之间的运输。两条压机线总吨位达6900t，最高冲次均可达18次/min，且该车间首次将重载型全向AGV应用到零件下线运输中，最大载重达1.5T，使用高级计划排程系统（APS），实现冲压生产计划自动排布。
车身车间分2层结构，一楼主要是门盖、底板1和装配线。二楼主要是侧围、底板2、总拼以及报交线。车身车间的设计生产能力是60JPH，即每小时可以完成60台白车身，年产量30万台。车间采用了大量智能制造先进新技术，拥有机器人946台，自动化率高达84%，是目前上汽大众自动化率最高的车身车间。
120JPH油漆车间是大众汽车集团全球首创的高产能油漆车间，可同时供应MEB工厂与安亭汽车三厂两个厂区。相较于传统的两个60JPH标准化油漆车间，节省建筑面积12%。车间生产能力每小时120台车，是标准化车间的2倍，达产后可完成60万辆的年生产量。
电池车间是上汽大众首个全铝电池壳体自制与电池包装配车间，规划年产能30万台。车间有两层的厂房。二楼是电池壳体线。壳体成品通过升降机自动输送到一楼的电池装配线。电池包完成装配后，通过升降机自动输送到二楼的电池包调序中心，每个电池包与车壳匹配后，通过连廊自动输送到总装车间。
在电池车间，上汽大众首次自制铝制壳体。由于铝合金的热膨胀系数是钢的2倍，焊接过程更容易产生焊接变形，因此对焊接精度要求更高。车间生产的电池包通过了203项严苛测试，同时，为了应对中国更加严苛的电池标准，上汽大众自主设计了整套热量控制系统，万一发生极端情况，可控制5分钟内明火不从电池壳体中冒出，保护驾乘者安全。据大众官方透露，新的电池包寿命将高于8年（12万公里）使用寿命（电池充放电循环测试达到1600次，每个循环相当于整车行驶350公里~550公里）。
总装车间设计生产能力为60JPH，达产后完成30万的年生产量。它是目前大众汽车集团自动化率最高的量产车型总装车间，自动化率达26.2%，模块化程度和柔性更高。车间二层平台有完备的输送线，车身通过连廊从油漆车间输送至总装车间；电池包则通过输送链到达总装车间二层平台，通过升降机下至底盘预装线。
驶下生产线的车辆将在路试区域进行测试。路试区域共有9种测试道路：正弦波路、凸出窨井路、下沉窨井盖、比利时路、粗石块路、摇摆路、蓝玄武岩路、钉头路、沥青路。全长712米。
未来，新工厂还将投产大众汽车集团多个品牌的全新一代纯电动车。基于MEB平台，上汽大众将建构起适合中国消费者的纯电动车“家族”，满足不同消费者的需求。

Classic summary of car interior and exterior
China's automobile industry started in the 1950s, while the automobile decoration industry started in the 1980s. It started with the introduction of localization by Shanghai Santana, FAW-Volkswagen JETTA, and Wuhan Citroën Beverly. The localization projects for the decorative parts of these imported models are also mainly for civilian and general industrial plastic plants, carpet factories, textile factories, adhesive chemical plants, coating chemical plants, and some predecessor factories such as: Shanghai Yanfeng Machine Mould Factory (now Yanfeng Visteon), Shanghai Automobile Carpet Factory, Shandong Wendeng Automobile Carpet Factory, SAIC Motor, Changchun FAW Interior Parts Factory (now Fawer Johnson), Yangzhou Second Plastic Factory, etc. However, this industry developed very rapidly. From 1990 to 2000, the automotive decoration industry blossomed all over the country. A large number of state-owned backbone enterprises and a larger number of small and medium private enterprises have emerged. For example: Shanghai Yanfeng Visteon, Ningbo Huaxiang, Johnson/Lear everywhere, Taiwan Quanxing Sub-factory, Wuhan Yunhe, Changshu Automotive Interior Material Factory, Yantai China Resources, FAW Fawer Johnson, etc.
Introduction to two-color injection molding technology process and mold characteristics
Two-color injection molding technology is also called two-component injection molding technology. This is a technology that uses two plastic materials to mix and inject plastic products. Its technical connotation is actually to use a mold component to shape the shape and form in the mold. Work welding, so the fundamental principle is to plasticize two different plastic materials, and then use molds for welding installation to achieve the purpose of two-color injection molding.
According to the plan, SAIC Volkswagen's MEB plant will be officially put into operation this year, and it is currently the largest pure electric vehicle plant in China. I heard that it has the world's most advanced digital production technology of Volkswagen Group, and more than 1,400 industrial robots are used. Let’s explore this new energy vehicle factory today.
