Different from the automatic machining production line, the processing object of the automatic machining production line is a single mechanical part, while the automatic assembly production line is mainly engaged in various assembly, detection, marking, packaging and other processes in the later stage of product manufacturing. The operation object includes multiple various parts and components, and the final completion is finished products or semi-finished products, Dalian automatic processing is mainly used in product manufacturing occasions with mature product design, huge market demand and long-term production of various assembly processes.

Its advantages include stable product performance and quality, less labor required, high efficiency, significant reduction of manufacturing cost of unit price products, minimum occupation of site, etc. Bearing, gear transmission, cigarette, computer hard disk, computer optical disk drive, electrical switch, relay, bulb, lock, pen, printed circuit board, small motor, micro pump, food packaging, etc. The structural principle of the automatic assembly line is very similar to that of the automatic machining line and the manual assembly line, except that the operators on the manual assembly line are workers, and the operators on the automatic machining line are various workstations or automatic machine tools, In the automatic assembly line, various automatic assembly machines complete various assembly processes.

The structure of the automatic assembly line mainly includes: · conveying system · various material distribution, stop and reversing mechanisms · various automatic loading and unloading devices · various automatic assembly machines · sensors and control systems. In addition, there may often be some manual processes to replace the assembly processes that are difficult to realize automation technically or uneconomical in cost, It consists of a hybrid automatic assembly line with automatic machine operation and manual operation.

(1) Conveying system the conveying system usually adopts various conveying lines. On the one hand, it is used to automatically convey workpieces, on the other hand, it is used to connect various automatic assembly machines into a coordinated system. Conveying systems usually operate continuously. The most typical conveyor lines, such as belt conveyor line and flat top chain conveyor line, are usually designed as straight line, and various automatic assembly machines are directly placed above the conveyor line. The automatic special machine and conveyor line are designed and manufactured on the basis of various aluminum profiles. After commissioning, the automatic special machine and conveyor line are connected and fixed through special connectors to make them a whole.

(2) Various material distribution, stop and reversing mechanisms because the workpieces are assembled one by one according to the arrangement order of special machines until all assembly processes are finally completed, usually a material distribution mechanism is designed in front of each special machine on the conveying line to separate the continuously arranged workpieces, and then various stop mechanisms are set to form the temporary storage position of workpieces required by each special machine. After the workpiece reaches the temporary stop position, the manipulator on the special machine grabs the workpiece from this 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 change machine grabs the workpiece from this position and returns it to the conveying line to continue conveying to the next special machine. When it is necessary to change the attitude of the workpiece, it is necessary to set an appropriate reversing mechanism, and then carry out the process operation after changing the attitude direction of the workpiece.
