Abstract: An automatic cord inserting structure for a venetian blind is fixed on an automatic slat insertion machine including a pushing mechanism and a slat fixing mechanism. The pushing mechanism pushes a slat toward the slat fixing mechanism, and the slat fixing mechanism includes a sliding rack and plural automatic infixing modules. Each automatic infixing module contains: a base having a front face, a rear face, a horizontal slot, and a vertical slot; two limiting pieces for limiting the cord assembly slid in the vertical slot; two abutting pieces fixed in the horizontal slot, and each abutting piece having a lock portion locked on the base and a contacting portion; two elastic units mounted among the base and the two abutting pieces to abut against the two abutting pieces, when the abutting pieces are not pushed by the slat, they are fixed in the horizontal slot.

Abstract: A processing module positioning system for window blind slats utilizes a position adjustment assembly to move plural processing modules to predetermined positions. The position adjustment assembly includes a servo motor employed to drive a connecting strap. A position control frame is fixed on the connecting strap, so that when the connecting strap is driven to move, the position control frame will be moved by the connecting strap to drive the processing modules connected on the position control frame to move. The position control frame can be connected to and disconnected from the processing modules.
