Flow path and the part of end are made of transition. The work-piece board, jig along with the line in the flow path is stopped by the pneudyne, smooth time, after finishing operation, it can go on next processing by man-made operation. There is ¡°A FLOAT AREA¡± between processes, adjust time/work-piece to the end of flow path, automatic transition to next flow path, it forms close system of transporting, according to the assembly work-piece and the specific require of consumer, it can be design plane single CYC, plane more CYC, stereo CYC, the equipment can be used together with other equipment combination.
