Abstract
A processing-object-supporting mechanism includes at least three devices each including a lift pin, a motor, and a drive controller. The lift pin contacts a processing object to support the processing object. The processing object is transferred between a conveying arm and the processing-object-supporting mechanism. The motor lifts and lowers the lift pin. The drive controller is configured to control the motor. The drive controller of each of the at least three devices is configured to control the motor of each of the at least three devices independently.
Claims11
A processing-object-supporting mechanism comprising:
- at least three devices each comprising:
- a lift pin to contact a processing object to support the processing object, the processing object being transferred between a conveying arm and the processing-object-supporting mechanism;
- a motor to lift and lower the lift pin;
- and
- a drive controller configured to control the motor, the drive controller of each of the at least three devices being configured to control the motor of each of the at least three devices independently.
A supporting method employed in a supporting mechanism, comprising:
- transferring a processing object after drive controllers independently control motors respectively such that distances from tips of lift pins to the processing object placed on a conveying arm or to a processing-object-receiving surface of the conveying arm all become equal, the processing object being transferred between the conveying arm and the supporting mechanism, the supporting mechanism including at least three devices each having one lift pin of the lift pins to contact the processing object to support the processing object, one motor of the motors to lift and lower the lift pin, and one drive controller of the drive controllers configured to control the motor.
A conveying system comprising:
- a conveying arm configured to convey a processing object;
- and
- a supporting mechanism with which the processing object is transferred from and to the conveying arm, the supporting mechanism including at least three devices each having
- a lift pin to contacting the processing object to support the processing object,
- a motor to lift and lower the lift pin, and
- a drive controller configured to control the motor,
- the processing object being transferred after the drive controller of each of the at least three devices independently controls the motor of each of the at least three devices such that distance from a tip of the lift pin of each of the at least three devices to the processing object placed on the conveying arm or to a processing-object-receiving surface of the conveying arm all become equal.
A processing-object-supporting mechanism comprising:
- at least three devices each comprising:
- a lift pin to contact a processing object to support the processing object, the processing object being transferred between a conveying arm and the processing-object-supporting mechanism;
- a motor to lift and lower the lift pin;
- and
- a drive controller configured to control the motor, the motor of each of the at least three devices being arranged to lift and lower the lift pin of each of the at least three devices provided in and fixed to an airtight chamber in which pressure is reduced, the processing object being transferred after the drive controller of each of the at least three devices independently controls the motor of each of the at least three devices in accordance with the pressure inside the airtight chamber such that distance from a tip of the lift pin of each of the at least three devices to the processing object placed on the conveying arm or to a processing-object-receiving surface of the conveying arm all become equal.
