AGV装配线系统
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及时供应时，可通过设置在装配工位的悬链急停开关，由人工控制，停止悬链运行。即使不按悬链急停，AGV系统也会通过控制台申请停止悬链运行。
When engine and front & rear suspension assembly can’t 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 hasn’t finished assembly, AGV will stop automatically and AGV console will

alarm and control the process chain to stop. After assembly, it will recover automatically.
（5）AGV在分装工位的运行速度可根据现场实际设置。
AGV running speed in subassembly station can be setup according to actual
situation.
6. 发动机装配升降工作台Engine Assembly Lifter Worktable
AGV发动机装配升降工作台是将发动机前悬总成举升到装配位置高度的设备，目前我公司应客户要求普遍采用纯机械传动的伸缩套筒式升降工作台。为适应各使用现场的不同要求，我公司将剪式液压机构升降工作台列为备选设备供用户选择。两者主要区别为前者采用直流伺服电机驱动升降，执行元件为滚珠丝杠。后者采用液压泵站驱动升降，执行元件为液压缸。
AGV engine assembly lifter worktable is the equipment that lifts engine front suspension final assembly to the assembly position. Now,
based
on
customer
requirements, our company mainly adopts pure mechanical driving extension sleeve lifter worktable. To meet different demands in various application fields, our company
makes
the
scissor
hydraulic lifter worktable to be an
optional device for customer to choose. The main difference between these two lies in the fact that the previous one uses DC servo motor to drive lifter and the executive component is ballscrew, while the latter adopts hydraulic pumping station to drive lifter and the executive component is hydraulic cylinder.
6.1 伸缩套筒式升降工作台Extension Sleeve Lifter Worktable
该装置主要由滑动工作平台、举升装置、手控盒等组成（如图升降工作台简图），

其中滑动工作平台在使用过程中可通过直线轴承组合的机构进行两个方向的水平移动，另外滑动工作台通过组合轴承结构可旋转一定的角度。举升装置是完成升降动作的主要装置，其主要由滚珠丝杠机构、一层起重链轮组合、二层起重链轮组合、电机减速机、齿轮传动及各伸缩套筒组成。该电机采用进口的直流电机、减速器一体机，滚珠丝杠及螺母等零件采用德国进口零件，性能可靠，传动稳定。 This equipment is formed by the sliding worktable, lifting device and manual control box, etc (See the lifter worktable sketch). Among them, the sliding worktable can move horizontally in two directions through straight bearing combination in the course of application. Besides, it can also rotate in certain angle by this structure. The lifting fixture is the main device to finish the action of lifting and lowering. It is composed of ballscrew, one layer lift chain wheel combination, two layers lift chain wheel combination, motor reducer, gear driving and each extension sleeve. The motor adopts the imported DC motor and reducer of one machine. Parts, such as the ballscrew and nut are imported from Germany. They are reliable in performance and stable in driving.
AGV举升装置可由手动操纵上升下降，操作人员可以通过操作配套在举升装置两侧的手控操作盒或脚踏开关实现举升装置的上升或下降。待AGV进入装配路段并跟踪上车身后，操作者松开滑动平台锁定装置，利用举升手控盒手动操纵举升装置升降。装配结束后，按动装配结束按钮举升装置自动复位至初始位置后人工锁定滑动平台。每个举升装置安装有编码器，可时时反馈提升的位置，举升的高度也可通过软件设定，设定需要举升的高度及极限高度。在发动机合装托盘上安装托盘位置传感器，用于监测发动机合装托盘在下降过程中是否与升降台分离，确保操作安全。
AGV lifting equipment can be operated manually to ascend and descend. Operator can run it through manual operation box or footswitch at the two sides of the lifting equipment. After AGV enters into assembly path and track the body, operator opens the lock equipment of slide flat and uses lifting manual control box to operate lifting equipment. After assembly, press the completion button, the lifting equipment will automatically return to its initial position. Then operator locks the slide flat. Each lifting equipment is installed with a coder, which can make feedback on the lifting position. Lifting height, including altitude to be lifted and maximum height can also be set through software. The pallet position sensor is installed on the engine decking pallet for the purpose of monitoring if the engine decking pallet has separated from the lifter table

in the course of lowering to ensure operation safety as a result.
