In the loading process of the base material, a jig is generally used as a device carrier, the jig clamps the base material, and then the base material is conveyed to an assembly station, and the assembled material is taken out by an assembly manipulator and then automatically assembled on the base material. After the jig clamps the base material, generally directly transport the jig to the assembly station of production line through the transport mechanism after, the assembly manipulator assembles the material to the base material, and the jig drives the base material to move to next station after the assembly is accomplished, until the material is assembled. In the actual assembly process, the factors of actual production sites are considered, and the assembly stations cannot be arranged on a single automatic assembly line in a straight line without limit, so that the length of a single line can be reduced only by setting a plurality of assembly lines, and the technical problems of switching circulation of jigs among different assembly lines and the like are involved.
