AGV工作过程描述AGV Working Process Description （1） AGV小车按控制台计算机指令行驶到后桥总成上装点，由操作人员依据生产计划完成后桥总成吊装，当将后桥总成从后桥分装线吊到AGV后桥举升装置上后桥夹具上并放稳后，操作人员经过车体上操作按钮向AGV小车发出完成上件确定信号，许可AGV向下一个站点运行；AGV will run upon console computer orders to loading point of rear axle final assembly and operator will complete this based on production plan. After the rear axle final assembly is moved from the rear axle subassembly line and placed well on the rear axle fixture of AGV rear axle lifting device, operator presses the button on the vehicle to sent signal, informing AGV that loading has been finished and allow AGV to move towards next station. （2） AGV小车行驶到发动机总成上装点，由操作人员依据生产计划完成发动机总成吊装，当将发动机总成从发动机分装线吊到AGV发动机举升装置上发动机夹具上并放稳后，操作人员经过车体上操作按钮向AGV小车发出完成上件确定信号，许可AGV向下一个站点运行AGV runs to loading point of engine final assembly and operator will complete engine final assembly suspending. When the engine final assembly is moved and placed well on the engine fixture of AGV engine lifting device from engine subassembly line, operator then sends confirmation signal of the completion of loading by pressing operation button on the body to inform AGV vehicle to move towards next station.（3） AGV小车按控制计算机指令行驶到等候地点； AGV moves to waiting place according to the order from control computer.（4） AGV小车在某一停留时间相对长站点（动力总成上装点或其它点）进行自动充电；AGV will charge itself automatically at one station (power train assembly loading point or other point) for relevant long waiting time.（5） AGV控制台检测工艺链上车体位置信号，当被装车体到位后调度已载有发动机前后悬挂总成AGV按预定时间、速度进入悬链下方（时间、速度依据生产线要求可经过车载显示器进行更改），在装配段快速向前运行，在预定区域捕捉预先固定在被装车身上合作目标。保持稳定跟踪状态后，人工操作举升手控盒或脚踏开关，进行举升装置上升操作，操作人员能够同时或单独发动机举升装置和后桥举升装置。在举升装置上升同时，打开平台锁定装置，使举升装置上平台处于浮动状态，操作人员一边按上升按钮一边夹具上车身定位销插入车身工艺定位孔。当举升到安装位置，全部螺栓安装孔均已定位。由装配人员安装固定螺栓，完成装配后装配人员按一下举升装置上装配结束按钮，AGV将自动落下举升装置到零点。目前后举升装置全部复位到零点以后，AGV将加速离开装配工位，在非装配段加载站备好发动机及后桥，完成一次工作循环。AGV console will test the signal of body position on the process chain. When loaded body has gotten to the position, AGV with engine and front & rear suspension assembly is dispatched according to set time and speed to the underneath of the suspending chain (time & speed can be changed through vehicle displayer according to requirements of the production line). Then AGV moves forward quickly in the assembly zone and captures in the prearranged area the cooperative target set in advance on the body. After tracking state is stable, manual control box or foot pedal switch is done by manual operation to raise the lifter. Operator can run simultaneously or separately the engine lifting device and rear axel lifting device. When the lifting device is raised, the lock fixture is opened to make the table floating. Operator presses the button for lifting and at the same time puts the body locating pins on the fixture into the process locating hole of the body. When getting to the installation position, all bolt installation holes are located. Then assembly workers will install the set bolts and press the button on the lifting fixture after completion of assembly. AGV will lower the lifting fixture to zero automatically. When all lifting fixtures reach zero, AGV will accelerate to leave assembly station. After equipped with engine and rear axle at loading station, AGV finishes one working cycle. 当发动机前后悬挂总成不能立即供给时，可经过设置在装配工位悬链急停开关，由人工控制，停止悬链运行。即使不按悬链急停，AGV系统也会经过控制台申请停止悬链运行。When engine and front & rear suspension assembly cant be supplied in time, make manual control by using emergency stop switch on the assembly station to stop suspending chain to run. Even without pressing the suspension chain emergency switch, AGV system can also apply to stop running through the console.当AGV进入报警工位（装配工位末端）而未完成合装时，AGV将自动停止运行，AGV控制台报警并控制工艺链停线，直到完成装配后自动恢复运行。When AGV enters into alarming station (at the end of assembly station) and hasnt finished assembly, AGV will stop automatically and AG
