TECHNICAL FIELD

[0001] The utility model relates to jig conveying technical field especially relates to a jig backflow mechanism. BACKGROUND

[0002] In the process of motor rotor heating and conveying, the motor rotor needs to be fixed and limited by the fixing jig. At present, more and more automation technologies are applied to the assembly line production, and automation makes the assembly line production faster, easier and more efficient. However, the backflow of the assembly line jig is not completely automated, and in some shorter assembly lines, the staff at the front and rear ends can complete the transmission of the jig from one side of the assembly line. However, when the length of the assembly line increases, manual operation method is difficult to realize. In addition, in the longer assembly line, the jig backflow line is not mature in space layout because of several different machines, and even some assembly lines directly accumulate the jig at the end of the line, and then manually transport to realize the backflow of the jig.

[0003] Such manual operation has many disadvantages. First, more jigs need to be prepared to realize the cache at the head and tail ends, increasing the cost. Second, manual transportation is sometimes a considerable physical activity, increasing the total workload of the staff, and thus is not conducive to popularization and use.
