  适合自动化装配生产线进行生产的产品通常为:
  The products suitable for automatic assembly line are usually:
  轴承、齿轮变速器、香烟、计算机硬盘、计算机光盘驱动器、电气开关、继电器、灯泡、锁具、笔、印刷线路板、小型电机、微型泵、食品包装等。


  Bearing, gear transmission, cigarette, computer hard disk, computer optical disk drive, electrical switch, relay, light bulb, lock, pen, printed circuit board, small motor, micro pump, food packaging, etc.
  自动化装配生产线的结构原理与自动化机械加工生产线、手工装配流水线是非常相似的,只不过在手工装配流水线上的操作者是工人,自动化机械加工生产线上的操作者是各种工作站或自动机床,而在自动化装配生产线上则由各种自动化装配专机来完成各种装配工艺。
  The structure and principle of automatic assembly line is very similar to that of automatic machining production line and manual assembly line, except that the operators on manual assembly line are workers, the operators on automatic mechanical processing production line are all kinds of workstations or automatic machine tools, while in automatic assembly line, various automatic assembly machines are used to complete various kinds of assembly workers Art. 
  为了简化结构,在自动化专机的设计中,通常将自动上下料机械手直接设计成专机的一部分,而且通常的上下料操作只需要两个方向的运动即可实现。
  In order to simplify the structure, the automatic loading and unloading manipulator is usually directly designed as a part of the special machine in the design of automatic special machine, and the normal loading and unloading operation only needs two directions of movement.
  所以这种机械手采用配套的直线导轨机构与气缸组成上下、水平两个方向的直线运动系统,在上下运动手臂的末端假设吸盘或气动手指即可。
  Therefore, this manipulator uses the matching linear guide mechanism and cylinder to form a linear motion system in two directions, up and down, horizontal. The end of the upper and lower motion arm is assumed to be suction cup or pneumatic finger.
  对于某些简单的工艺操作,专机不需要将工件从输送线上移出,可以在工件在输送线上的输送过程中直接进行,例如喷码打标、条码贴标操作,这就使专机的结构大大简化;有些工艺需要使工件在静止状态下进行,这时就需要通过挡停机构使工件停留在输送线上,然后直接进行。
  For some simple process operations, the special machine does not need to remove the workpiece from the conveying line, but can be directly carried out in the conveying process of the workpiece on the conveying line, such as spray code marking and barcode labeling operation, which greatly simplifies the structure of the special machine; some processes need to make the workpiece in the static state, so it is necessary to stop the workpiece on the conveying line, And then go straight ahead.
  而有些工序不仅需要工件在静止状态下进行,而且还需要一定的精度,例如激光打标操作,这时如果仅仅将工件挡停在输送线上还不够,因为输送线通常是连续运行的,在输送线的作用下工件仍然会产生轻微的抖动,需要设计气动机构将工件向上顶升一定距离,使工件脱离输送皮带或输送链板后再进行工序操作,完成工序操作后再将工件放下到输送皮带或输送链版上继续输送。
  However, some processes not only require the workpiece to be carried out in a static state, but also need a certain precision, such as laser marking operation. At this time, it is not enough to stop the workpiece on the conveyor line, because the conveyor line is usually continuous operation, and the workpiece will still produce slight shaking under the action of the conveyor line. Therefore, it is necessary to design a pneumatic mechanism to lift the workpiece upward for a certain distance After the workpiece is separated from the conveyor belt or conveyor chain plate, the process operation is carried out, and after the operation is completed, the workpiece is put down on the conveyor belt or conveyor chain plate to continue conveying.
  除典型的直线形式外,为了最大限度地节省使用场地,有时还可以采用一种环形形式,如图2所示。由于平顶链输送线能够自由转弯,所以非常适合作为这种环形生产线的输送系统。
  In addition to the typical straight line form, in order to minimize the use of space, sometimes a circular form can be used, as shown in Figure 2. Because the flat top chain conveyor line can turn freely, it is very suitable as the conveying system of this kind of circular production line.
