The invention discloses a six-part full-automatic assembly machine for invisible zipper puller and is characterized in that a moving assembly that is connected with a power device is arranged at the table top of a frame; twelve die cavities for fixing zipper pullers are arranged at equal intervals on the margin of the division main rotor plate of the moving assembly; and a zipper puller feeding mechanism, a zipper puller detection mechanism, a zipper puller spring feeding mechanism, a spring detection mechanism, a triangular collar feeding mechanism, a triangular collar detection mechanism, a horse hooker feeding mechanism, a copper pin feeding mechanism, a copper pin detection mechanism, a puller detection mechanism, a puller detection mechanism rejected puller discharge mechanism, and a qualified product discharge mechanism are arranged on the frame and used for assembling zipper pullers. The six-part full-automatic assembly machine integrates the functions of two machines, the detection mechanisms are arranged behind the corresponding feeding mechanism to automatically identify parts in the die cavities, and the start-up or shut-down of the assembly machine is automatically controlled according to the assembly information of parts, so as to prevent defected parts from entering the next procedure or prevent idle running of the assembly machine, as a result, the rate of rejected products is reduced and the assembly machine is guaranteed to run safely and reliably.
