摘要： PROBLEM TO BE SOLVED: To reduce an impact force when electrode come into contact with a work and to execute suitable press for welding. SOLUTION: Electrodes 2a and 2b of a welding gun 1 are brought into contact without interposing any work, a motor current is monitored, and the position reached a position corresponding to a set torque is made to be a contacting position X. And a positional desired value X-d is set in consideration of the plate width (d) of the work 20 at the time of pressing and welding for the actual work, and electrode 2a and 2b are moved at a high speed by controlling the position. Next, an excess position for obtaining a welding pressure is selected as a positional desired value, the position control is executed, electrodes 2a and 2b are moved at a pre-set low speed until electrodes come into contact with the surface of the work 20, and the contacting state is judged by monitoring the motor current. After contact, a command value making electrodes 2a and 2b move to the excess position at a high speed is applied, the motor current is limited to the value corresponding to the set welding pressure, and the welding pressure is controlled.

摘要： PROBLEM TO BE SOLVED: To facilitate welding in conformance with an action of a work by synchronously and integratively controlling a welding force and a welding current in spot welding. SOLUTION: An electrode for spot welding is driven for traveling and welding force by a servo motor 30. A welding force controller 27 detects a welding force through a driver 26 corresponding to an electric current flowing to the servo motor 30 and controls so that the welding force is changed according to the set condition. The welding current flowing to the electrode for spot welding is controlled by a welding current controller 28. The welding current controller 28 and the welding force controller 27 are synchronized/controlled by a robot CPU 20 through a system bus 21. The robot CPU 20 controls, in accordance with the welding condition data 22 stored in a memory, so that the welding force and the welding current are synchronized/changed in a plurality of stages.

摘要： The spot welding electrodes are driven by the servomotor (30) so as to be moved to and pressured against a work surface. The welding pressure controller (27) detects welding pressure corresponding to current flowing through the servomotor (30) via a driver (26) and controls the welding pressure so as to be changed according to the set welding pressure condition. The welding current flowing through the spot welding electrodes is controlled by the welding current controller (28). The welding current controller (28) and the welding pressure controller (27) are both controlled synchronously by the robot CPU (20) via the system bus (21). The robot CPU (20) controls the welding pressure and the welding current on the basis of the welding condition data (22) stored in a memory, so as to be changed in synchronism with each other at a plurality of welding stages, respectively. By doing this, it is possible to control the welding pressure and the welding current during the spot welding synchronously and systematically, thus realizing a spot welding control adaptive to work behavior.

摘要： PROBLEM TO BE SOLVED: To eliminate the need of additional parts for working out the original position by correcting the original position of an welding gun actuator based on the abrasion volume of both electrodes. The abrasion volume of one electrode is calculated by a driving position of a welding robot, and the abrasion volume of the other electrode is calculated by a driving position of the welding gun actuator. SOLUTION: One electrode 41 is pressed to a reference abutting portion 10 by driving a welding robot 2, and the abrasion volume δ1 of the pressed electrode 41 is obtained by the comparison with an electrode position in a non- abrasive state. A pair of electrodes 41 , 4u are touched and abutted to each other by driving a welding gun actuator 5. The total sum δ1 of the abrasion volume of a pair of the electrodes 41 , 4u is obtained from the difference between the present electrode contact position and the electrode contact position before abrasion of the welding gun actuator 5, and the abrasion volume δu of the other electrode 4u is obtained by subtracting δ1 horn δ1 . The original position of the welding gun actuator 5 is corrected based on the original position X0 δ1 , and δu after the electrode abrasion.

摘要： PROBLEM TO BE SOLVED: To cope with an abnormality by judging whether or not the difference between the output value of the physical system to be controlled and the reference value of a norm model corresponding thereto is within the predetermined allowable range, and selecting whether or not the parameter identification and repair are executed when it is judged that the difference is outside the allowable range. SOLUTION: The output value 13 (the axial force) of the physical system to be detected by an output value detecting means 15 is compared with the reference value of a norm model to be detected by a reference value detecting means 17, and the difference therebetween is operated by a comparing means 16. An input part 23 is provided, in which a person selects whether or not the parameters I (equivalent inertia), D (equivalent damping), and K (equivalent spring) of the norm model are identified and repaired when the difference is judged to be outside the allowable range by a judging means 20. When the parameters I, D, K are identified and repaired, identification and repair of the parameters are executed by processing parts 24, 19.
