[0002] Assembly line equipment is a cargo handling machine that continuously transports goods on a certain route, also known as a conveyor line or conveyor. According to the conveying series products, it can be roughly divided into seven types of assembly lines: belt assembly line, plate chain line, multiple chain line, plug-in line, mesh belt line, suspension line and roller assembly line. Generally, it includes traction parts, load-bearing components, driving devices, tensioning devices, redirecting devices and supporting parts. Conveyors can be used for horizontal, inclined and vertical transportation, and can also form spatial transportation lines. The transportation lines are generally fixed. The assembly line has a large transportation capacity and a long transportation distance, and can also complete several process operations simultaneously during the transportation process.
