Under the high temperature, a cars engine lubrication systems reliability requirements are relatively high, especially with high-power engine. And the oil cooler can maintain engine under reliable lubrication in work, improving their reliability and life expectancy, lowering precision of engine manufacturing. It is an essential supporting device for the truck engine. With the acceleration of the process of modernization and the rapid development of the auto industry, the demand of oil cooler market increases quickly, especially for disk-oil coolers, because of its advantages of structure and properties.Oil cooler assembly process is a very important part in the manufacturing process. The assembly quality will do a direct impact on the oil cooler sealing performance. However, as the restrictions of the oil cooler of the structure, for a long time, the assembly process has relied on hand not only at home but also abroad. It is inefficient, labor-intensive. And assembly quality is mainly due to artificially ,this made the stability and reliability of oil cooler is not high. An automatic assembling line for stainless steel flat-fin oil cooler has been planed to set up at Yangzhou Tongyang Oil Cooler Co., Ltd. However, due to its structure feature, its not realistic to set up the fully equipped automatic assembly line of oil cooler. So based on the original manual assembling line, building semiautomatic assembly line is a ideal method which accord with real situation with the this firm at present. It can not only improve the assembling quality of oil cooler, but also save a lot of money. Automatic assembly line combines mechanical systems (including assembly line, assembly manipulator, positioning devices, compaction equipment, etc.), pressure systems, electrical systems and PLC control system
