Description

The techniques disclosed herein relate to nozzle filter replacement jigs and component mounters.

Conventionally, as an air filter insertion jig for inserting an air filter into a suction nozzle, a jig described in Japanese Patent Application Laid-Open No. 2010-177509 (Patent Document 1 below) is known. The suction nozzle is composed of an insertion part for inserting the air filter from the nozzle side, a grip part having a convex elongated shape to be gripped when the suction nozzle is attached and detached, and a suction part having a nozzle hole at the tip. Has been done. Inside the suction nozzle, a suction passage is provided in which the diameter becomes smaller toward the tip of the component suction. The insertion portion has an insertion groove into which the air filter is inserted from the side and a suction passage hole forming a part of the suction passage. The insertion groove has a width and height substantially the same as the diameter and thickness of the air filter, and the diameter of the suction passage hole is smaller than the diameter of the air filter. Further, on the opposite side of the insertion groove, an extrusion rod insertion hole for inserting an extrusion rod when removing the air filter is provided.

On the other hand, the jig has an air filter fixing portion for fixing the suction nozzle and a filter insertion rod for pushing out the air filter. When replacing the air filter of the suction nozzle, the suction nozzle is taken out from the nozzle stocker, the extrusion rod is inserted through the extrusion rod insertion hole, and the used air filter is pushed out. Next, the grip portion of the suction nozzle is inserted into the air filter fixing portion, and the suction nozzle is fixed to the air filter insertion jig. Next, the air filter is extruded by the filter extrusion rod and inserted into the insertion groove of the suction nozzle. Further, when the filter extrusion rod is pushed in as it is, the nozzle release rod pushes the side portion of the air filter to remove the suction nozzle from the air filter insertion portion.
