The invention discloses an intelligent assembler with a K-shaped accessory chain, relates to the technical field of chain assembly, and solves the problem of low assembly efficiency of a traditional chain. The intelligent assembler comprises a machine tool worktable and a PLC automatic control terminal; the machine tool worktable is provided with a positioning clamp for fixing a chain piece and a K-shaped accessory; an automatic assembly mold is arranged on one side of the positioning clamp; a chain mold transverse feeding mechanism matched with the positioning clamp is arranged on the outer side of the positioning clamp; a part blanking mechanism matched with the automatic assembly mold is arranged on the outer side of the automatic assembly mold; the upstream section of the automatic assembly mold is connected with a single-section feeding mechanism; the single-section feeding mechanism is connected with a single-section vibration disc; a bracket is arranged on the machine tool worktable, and is provided with a chain pressing assembly mechanism; and the chain pressing assembly mechanism is positioned rightly above the automatic assembly mold. The chain intelligent assembler is high in automation degree, excellent in chain assembly quality, high in chain assembly speed, stable in performance and low in failure rate.
