The development of automatic production line has experienced two years: rigid automatic production line and flexible active production line. The transportation of rigid processing automatic production line is divided into the forms of ratchet and pawl, swing rod, lifting foot, motorized raceway, etc. With the development of machine tools in processing, the automatic production line composed of them gradually replaces the active production line composed of modular machine tools, which is called flexible processing automatic production line.

After the automatic production line is transported by a truss manipulator, the conveying distance can be changed at will according to the equipment of the machine tool. The orientation of the device between the machine tool and the machine tool on the automatic production line is no longer the same as that of the rigid conveying. The strict device is carried out according to the requirements of the conveying distance or multiple of the distance, and the conveying speed can also be changed according to the production rhythm and the conveying interval. The important aspect of the true performance of flexible transportation is that when the products of the processed parts are changed, the transportation part will not be unsuitable and will be completely replaced, just change the transportation procedure and the structure of the manipulator part.

On the one hand, the use of truss manipulator to transport is more advanced, and the overall automation and intelligence of the active production line for flexible machining of machine tools are in harmony. Therefore, truss manipulators are more and more used in the active production line of flexible machining today, so that the entire production process can be controlled through the information flow system. In the process of processing and transportation, all kinds of information required are collected, processed and reacted, and the machine tools or transportation equipment are controlled hierarchically through computers or other control devices (hydraulic and pneumatic devices, etc.). The information flow system is composed of management computer, logistics control computer, unit control computer, CNC machine tools and information transmission network.

The active processing production line composed of truss manipulators and machine tools manufactured by Pinzhan Automation Equipment can complete the active grabbing, loading, unloading, clamping, shifting and turning of workpieces, and changing the order of workpieces in all technological processes, which can greatly save labor costs and improve production efficiency. It is especially suitable for processing large quantities of small parts.
