Abstract: When operations of control sections 102a and 102b are changed, if the type of unprocessed data is not changed, the whole of table A′ of control section 102b corresponding to table A of control section 102a is cleared, table B is created in an area different from table A′, the old type data stored in table A is converted to new type data and stored in table B. After this data type conversion processing is started, difference data (old type data) written in control section 102a is stored in table A′ after all data is cleared, this stored difference data is converted to new type data and written in table B and the corresponding data in table A′ is cleared. When there is no more difference data through this data type conversion processing, switching between the operational and standby systems is performed.

Abstract: In a spot welding gun which is made up of a gun main body which is operated for equalization by a driving source, a stationary electrode tip which is immovable relative to the gun main body, and a movable electrode tip which is connected to a pressing source, both electrode tips are pressed to a workpiece with an even force, to thereby perform a high quality spot welding. The driving source is controlled such that the electrode force of the stationary electrode tip, by the driving source, to the workpiece becomes substantially zero. In this manner, there occurs no difference in the electrode forces by both the electrode tips to the workpiece.

Abstract: When a workpiece which is made up by laminating a plurality of plates of different thicknesses is welded by using a spot welding gun having a pair of electrode tips, the electrode force to the workpiece by one of the electrode tips, which is positioned on the side of a thinner plate, is made larger that the electrode force to the workpiece by the other of the electrode tips. The contact pressure on the side of the thinner plate becomes larger with the result that the contact resistance decreases. Therefore, the nugget on the side of the thinner plate becomes smaller than the nugget on the side of the thicker plate.

An amplifier circuit board is provided so as to mount thereon appropriate inverters by selecting out of those corresponding to respective kinds of servomotors and an inverter for the welding gun. A servo software corresponding to each of the inverters is called out of a memory device by discriminating the kind of each of the inverters. In a method of teaching the welding robot in which the welding gun is opened and closed by a servomotor, plural kinds of opening and closing patterns of the welding gun are set in advance. An appropriate opening and closing pattern is selected out of the plural kinds of opening and closing patterns in accordance with the motion of the robot arm, and the selected pattern is made the teaching data relating to the opening and closing of the welding gun.

Abstract: A welding robot has a gun main body, a stationary electrode tip which is immovable relative to the gun main body, and a movable electrode tip which is mounted on the gun main body and is opened and closed by a pressing source. The gun main body is movable by a driving source in a direction in which both the electrode tips lie opposite to each other. In teaching the welding robot by the movement thereof to each weld spot position of a workpiece, the movable electrode tip is moved in a closing direction relative to the gun main body by the pressing source in a state in which the gun main body is kept stationary at a predetermined position relative to the gun support bracket. The stationary electrode tip is moved in the closing direction by a relative movement of the gun main body relative to the movable electrode tip after the movable electrode tip has come into contact with the workpiece. A position at which the stationary electrode tip contacted the workpiece is detected.

Abstract: A phase adjusting apparatus for use in an assembling machine for assembling first and second workpieces including a movable frame which is arranged to move into and out of the space formed between the two workpieces. Prior to coupling the two workpieces, the movable frame is moved to enter the space and a first movable table and a second movable table on the movable frame are used to adjust the phase of a rotary body on the first workpiece and the phase of a rotary shaft on the second workpiece to another. After removing the movable frame from the space, the two workpieces are then brought together so that the rotary body and the rotary shaft are coupled to each other.
