With the development of advanced technologies such as electronic technology, computer technology, numerical control, and robotics, automatic arc welding robot workstations have become increasingly mature, which not only stabilizes and improves welding quality, improves labor productivity, improves labor intensity, but also works in harmful environments. It reduces the requirements for workers’ operating technology, shortens the backup period for product retrofits, and reduces corresponding equipment investment.
Despite this, in the welding process of automatic arc welding robot workstations, welding defects such as welding offset, undercut, and air holes and various failures are inevitable. For example, if the battery of the data storage on the robot encoder is not powered or damaged, it is necessary to disassemble the battery installation box of the encoder pulse data storage and measure the voltage of each battery of the battery box, which is below 1.4V, and the battery voltage is obvious. Low, replace the battery and reset the fault.
It is also possible to detect the failure of the servo amplifier control board in the purchasing a two-axis all-round rotary table welding arc welding robot workstation controller. It is necessary to check the two DC link voltage detection screws above the servo amplifier LED to confirm the DC link voltage. If the voltage is higher than 50V, the servo amplifier control board is in an abnormal state. The voltage is lower than 50V, which can be judged to be in a normal state.
On this basis, further observe the LED color of the servo amplifier control board, confirm that the power supply voltage output is normal, there is no external emergency stop signal input, and communication with the robot motherboard can eliminate the damage of the servo amplifier control board.
If the line is damaged in the automatic arc welding robot workstation, the robot controller can be connected to the external cable of the robot body; and the plug is unplugged, and the battery line of the data storage on the encoder is checked to judge the code. The battery line of the data storage on the device is damaged.
