Spot welding robot An industrial robot used for spot welding automation. The world's first spot welder began to be used in 1965. It was the Unimate robot launched by Unimation Corporation of the United States. In 1987, China developed its first spot welding robot, the Huayu-I type spot welding robot.

Advantage editing
The spot welding robot consists of a robot body, a computer control system, a teaching box and a spot welding system. In order to meet the requirements of flexible operation, the welding robot usually adopts the basic design of the joint industrial robot, and generally has six degrees of freedom. : waist, big arm turn, small arm turn, wrist turn, wrist swing and wrist watch. The driving method is hydraulic drive and electric drive. Among them, the electric drive has the advantages of simple maintenance, low energy consumption, high speed, high precision and good safety, so it is widely used. The spot welding robot performs spot welding operations according to the actions, sequences and parameters specified in the teaching procedure. The process is fully automated and has an interface for communication with external devices, which can accept the upper level master and management computer through this interface. Control commands work.

Spot welding robot operation flow
1. Ensure that the water and electricity are complete and that the alarms of the safety door and the grating are released.
2. In the robot manual state, move the robot cursor to the alarm bar and press all to confirm that the weld enable is on (the blue button in the lower left corner of the teach pendant screen is not crossed).
3. Select the input/output interface on the robot teaching box to check whether the robot's work and work completion signal are reset. If it is not reset, reset it; then, turn the status selector switch on the robot teaching box to the automatic gear. The program pointer on the teaching box will point to the CELL main program. {If the program pointer on the teaching box does not point to the CELL main program, you need to change the status selector switch on the robot teaching box to the manual gear, and then select it in the R1 folder. The cell program (press the Enter key to select), then the state selection switch on the robot teaching box is turned to the automatic gear}, and the robot switches to the automatic running state.
4. Press the alarm reset button on the main station to set the manual/service/automatic selector switch to the automatic position.
5. Confirm that the program pointer on the teach pendant points to the CELL main program.
6. Turn on the servo power: press the servo power-on button on the operation box to make the servo power of the positioner turn on at the same time, the corresponding green servo power light is on, and the red light of the alarm reset is extinguished. If it is not extinguished, press Several times this alarm reset button; then press the start button (2s), the corresponding indicator lights at the same time, the workstation will enter the automatic running state.
Simple problem handling
1. If the robot stops for any reason, turn the robot and the operation box to manual, then press the alarm reset on the operation box one or two times, then move the robot cursor to the alarm bar and press all to confirm, reset the alarm. Then hit the teach pendant to Auto and repeat step 6 above.
2. If the electrode tip is off, after the other robots work, the teaching box and the console will be in manual T1 mode. If it is convenient to install, press the robot and restart the robot (press one or two times on the operation box). Reset the alarm, then move the robot cursor to the alarm bar, press all to confirm, reset the alarm, then turn the teaching box to automatic, then repeat step 6 above; if it is not installed, the robot needs to be Operate to a convenient location (do not hit anything), move the robot to the previous point of the stopped position after changing it (move the robot to a position near the point, then select the sentence to the point, press and hold the check until The robot stops automatically, and it does not collide during the process. It can be restarted.
    
Development trend editor
The first large-scale use of spot welding robots will be in developed areas. As industrial transfers progress, manufacturing in developed regions needs to improve. Based on the growing reality of worker costs, the application of spot welding robots has become the best alternative. In the future, the wide range of applications of spot welding robots in China will be concentrated in Guangdong, Jiangsu, Shanghai, Beijing and other places, and the number of spot welding robots will account for more than half of the country. The growing spot welding robot market and huge market potential attract the attention of the world's leading robot manufacturers. At present, China's imported spot welding robots are mainly from Japan, but with the emergence of companies with their own intellectual property rights such as "robots", more and more spot welding robots will be made in China.
