Adsorption nozzle, component transfer apparatus, and attitude control method of adsorption nozzle

An attitude control method of an adsorption nozzle having an axial nozzle member having a tip portion configured to adsorb a component;

• a holder member configured to slidably hold the nozzle member in a nozzle projection direction parallel to an axis line of the nozzle member;
• an urging member configured to generate an urging force to slide the nozzle member in the nozzle projection direction and cause the tip portion of the nozzle member to be projected from the holder member;
• and a locking part configured to locking the nozzle member projected from the holder member by the urging force, to position the tip portion of the nozzle member at a projection limit position, the method comprising:
• controlling an attitude of the nozzle member by giving a rotational movement to the nozzle member in a rotation direction when the nozzle member is projected from the holder member by the urging force in the nozzle projection direction, the rotational movement being given by locking the nozzle member at a first locking position and a second locking position which are asymmetric with respect to the axis line of the nozzle member, the rotation direction uniquely being determined by a relative relationship between the first locking position and the second locking position with respect to the axis line.

An adsorption nozzle, comprising:

• an axial nozzle member having a tip portion configured to adsorb a component;
• a holder member configured to slidably hold the nozzle member in a nozzle projection direction parallel to an axis line of the nozzle member;
• an urging member interposed between the nozzle member and the holder member and configured to generate an urging force in the nozzle projection direction for causing the nozzle member to slide in the nozzle projection direction and projecting the tip portion of the nozzle member from the holder member;
• and
• a locking part configured to locking the nozzle member projected from the holder member by the urging force, to position the tip portion of the nozzle member at a projection limit position,
• wherein the nozzle member has a hollow structure inside which configures a suction path leading to the tip portion, and
• the locking part includes a rotation restricting pin inserted along a direction orthogonal to the axis line and passing into the suction path to attach to the holder member and locks the nozzle member at a first locking position and a second locking position which are asymmetric with respect to the axis line by the rotation restricting pin, to give a rotational moment to the nozzle member projected in the nozzle projection direction by the urging force, in a rotation direction which is uniquely determined by a relative relationship between the first locking position and the second locking position with respect to the axis line.
