Assembly line, also known as assembly lines, production on an industrial means of production work of each one processing unit only focus on one segment, in order to improve efficiency and yield; according to pipeline transportation methods can be divided into: Belt assembly line , plate chain, speed chain, plug-in line, belt line, suspension lines and drum lines seven class lines. Generally includes pulling elements, bearing member, drive means, tensioning means, redirecting means and the support member and other components. Pipeline scalable high, according to the needs of the design throughput, transmission speed, assembly station, accessories (including quick connectors, fans, lights, sockets, process billboards, Stands, 24V power, wind batch, etc.), so popular businesses welcome; is the effective combination of man and machine, the most fully embodies the flexibility of the device, it will transport systems, pallet and online plane, a combination of organic detection equipment to meet the delivery requirements of many varieties of products. Transmission of the transfer line synchronous transmission / (forced) to be non-synchronized transmission / (flexible type), selected according to the configuration can be achieved and conveying assembly requirements. Indispensable in the business of conveying line mass production.
