Abstract:
A component mounting machine comprising:a component feeder unit having a component accommodating part for accommodating components, a feed-out part for feeding the accommodated components one by one, and a component takeout part adapted to remove the fed components; a component feed section for supporting a plurality of the component feeder units to be set thereon; a movable nozzle unit for removing a component from the component feed section and for mounting the component onto an object, wherein the component accommodating part is set outside a range of movement of the nozzle unit; a robot unit for driving the nozzle unit; a control unit for controlling operations of the nozzle unit and robot unit; and an opening/closing cover for isolating the component takeout part and the component accommodating part from each other when the opening/closing cover is in a closed position, the opening/closing cover comprising an upper cover arranged to pivot on a machine fulcrum at a machine upper portion, a sub-cover arranged to pivot on a cover fulcrum at a front end portion of the upper cover, and a guide mechanism for regulating operation of the sub-cover, wherein the guide mechanism is adapted to regulate movement of the sub-cover such that when the sub-cover moves together with the upper cover, the sub-cover does not interfere with a movable part of the nozzle unit, and such that when the component feeder unit is set on the component feed section and the sub-cover is moved to the closed position, the component takeout part of the component feeder unit is isolated by the sub-cover while the component accommodating part of the component feeder unit is exposed so as to be accessible by an operator, whereby the movable part of the nozzle unit can be isolated from the component accommodating part of the component feeder unit so that there is insufficient space through which a foreign object can be inserted toward the movable part of the nozzle unit.
