Structural Form Of Automatic Assembly Line

The automatic assembly line is mainly engaged in various assembly, detection, marking, packaging and other processes in the later stage of product manufacturing in assembly automation industries. The objects of operation include many kinds of parts and components, and the final finished products or semi-finished products are mainly used in product manufacturing occasions with mature product design, huge market demand, multiple assembly processes, and long-term production.

Automation Equipment Design:

The structure of the automatic assembly line mainly includes conveying systems, all kinds of separation, stop and reversing mechanisms, all kinds of automatic loading and unloading devices, all kinds of automatic assembly machines, sensors and control systems. In addition, there are often some manual operation processes, which are used to replace the assembly processes that are difficult to realize automation technically or uneconomical in cost, and constitute a hybrid automatic assembly line that includes both automatic machine operation and manual operation.

(1) conveying system

the conveying system usually adopts various conveying lines, whose functions are on the one hand to automatically transport workpieces, and on the other hand to connect various automatic assembly special machines into a coordinated operation system. The conveying system is usually operated continuously. The most typical conveyor lines are belt conveyor line, flat top chain conveyor line, etc.

(2) various splitting, stopping and reversing mechanisms

since the workpieces are assembled one by one according to the arrangement order of the special machines until the final completion of the whole assembly process, usually in front of each special machine on the conveyor line, a material separating mechanism is designed to separate the continuously arranged workpieces, and then various stop and stop mechanisms are set to form the temporary storage position of workpieces required by each special machine. After the workpiece reaches the temporary storage position of the stop, the manipulator on the special machine grabs the workpiece from the position and puts it into the positioning fixture after being confirmed by the sensor, and then carries out the assembly process operation. Finally, the manipulator on the exchange machine grabs the workpiece from this position and sends it back to the conveying line for further conveying to the next special machine.   when it is necessary to change the attitude of the workpiece, it is necessary to set up a suitable reversing mechanism, change the attitude direction of the workpiece, and then carry out the process operation.

(3) various automatic loading and unloading devices

Since the main assembly process is completed by various automatic assembly special machines, various automatic assembly special machines naturally need their own automatic loading and unloading devices, and the most widely used ones are vibration disk and manipulator. The vibration disk is used to automatically transport small parts, such as screws, nuts, rivets, small stamping parts, small injection parts, small die-casting parts, etc., while the manipulator can grasp a wider range of objects, which can not only grasp very small parts but also grasp parts with a certain size and weight.
