(2) Coordinated control ...

1. Welding deviation. The cause of welding deviation: welding deviation is that the welding angle deviates from the weld in the process of welding operation, and the welding is not carried out along the weld. Welding deviations can be caused by incorrect torch finding points or incorrect torch positioning. Actions to be taken in the event of a weld deviation: the operator ...

1. Turn on the machine. The operator turns on the power switch "ON" on the control cabinet and adjusts the operating mode to "TEACH" → "Teach-in mode". 2. Welding program editing. Enter the program editing state: first create a new program on the main menu, display the new program ...

1) Scrub the axes of the robot; 2) Check the accuracy of TCP; 3) Check the oil level of the residue cleaned; 4) Check whether the zero position of each axis of the robot is accurate; 5) Clean the filter screen behind the water tank of the welding machine; 6) Clean the filter at the compressed air intake; ...

The robot welding adopts argon-rich mixed gas shielded welding, and the welding defects in the welding process generally include welding deviation, undercut, porosity, etc., which are analyzed as follows: (1) The welding deviation may be due to the incorrect position of the welding or the problem of finding the welding gun. At this time, consider T...

1. The structure of the conveyor belt feeding at the front end of the claw of the palletizing robot generally has a national standard for the roller conveyor belt for bag grabbing, and it is necessary to adopt a standard interface, and for the belt conveyor belt, it is necessary to consider how to achieve it. 2. The selection of the palletizing robot model, the load capacity of the robot ...

1. Failure of the operating system. That is, the soft fault of the automatic welding robot, often data loss or the operating system can not be started, the automatic welding robot has a protection function, can send an alarm signal to the fault source, only need to repair the fault according to the alarm reminder, in case the data ...

1. Adjust the welding current Welding current is the circuit current flowing through the welding rod and welding wire during welding, when setting the welding current, it is necessary to refer to the specifications of the weld and the penetration depth and width, the welding current is too large or too small will affect the welding quality, and the welding current is too large.

1. Stabilize and improve the welding quality to ensure its uniformity. When using robot welding, the welding parameters of each weld are constant, and the quality of the weld is less affected by human factors, which reduces the requirements for the operation technology of workers, so the welding quality is stable. And when manual welding ...

1. The undercut may be due to improper selection of welding parameters, the wrong point of view of the welding gun or the orientation of the welding gun, and the welding parameters can be appropriately adjusted to change the welding parameters, and the welding gun posture of the automatic welding robot and the relative orientation of the welding gun and the workpiece can be adjusted. 2. The welding deviation may be welded.

1. Ensure that the water and electricity are complete, and ensure that the alarm of the safety door and grating is lifted. 2. In the manual state of the robot, move the robot cursor to the alarm bar and press All to confirm that the welding enable is on (the blue button in the lower left corner of the teaching box screen is not crossed). ...

The weld is not fully penetrated Incomplete weld penetration is one of the common defects in robotic welding. When this happens, the depth of the weld is not enough, which leads to a decrease in the strength of the weld. There can be a variety of reasons why a weld is not fully penetrated, such as insufficient heat input or incorrect welding parameters. ...

1. Mechanical production With the intensification of the welding task of the mechanical production operation, the welding operation has poor working conditions, the heat radiation is large, and it is a dangerous operation, and there are many large-scale equipment in the mechanical production, which also increases the difficulty of welding, and the welding robot ...

Advantages of palletizing robots: 1. High productivity Productivity is improved with the help of functions, structures, and special tools that optimize the use of handling and palletizing. Fast and large action scale, make a great contribution to the progress of production function, the selection of hollow structure to avoid gripper cable problems, handling ...

1. MIG welding (MIG/MAG arc welding): This welding method uses the continuously fed welding wire and the burning arc between the workpiece as a heat source, and the gas sprayed by the torch nozzle protects the arc for welding. The inert gas is generally argon. 2. TIG welding (inert ...

1. The setting of the welding joint of the spot welding robot: The solder joints of the spot welding robot are carried out in the teach pendant, which has multiple functions in the teach pendant, and the solder joints can be set according to the specifications of the workpiece to be welded and the reasonable teaching sequence.

1. Generally, when performing precision welding, the electrode rod needs to be adjusted to the corresponding position first, so that the motor can just touch the weldment, and the welding robot is the same. In addition, the electrode arms need to be balanced with each other to achieve good welding quality. ...

From November 7 to 11, 2017, the 19th China International Industry Fair was held in Shanghai. Hyundai Robot comprehensively demonstrated 11 kinds of products, including the correct arc welding system, high-speed spot welding system, and large-scale high-speed stamping and handling robot system. Among them, the LCD vacuum robot imported from Korea will ...

Workstations (Units) If the workpiece does not need to be dislocated during the entire welding process, the workpiece can be positioned on the table with a fixture, which is the simplest system. However, in actual production, more workpieces need to be dislocated during welding, so that the weld is in a better position.

1. If the robot stops for some reason, hit both the robot and the operation box to the manual, then press the alarm reset on the operation box once or twice, then move the robot cursor to the alarm bar, and press all to confirm to reset the alarm, and then hit the teaching box to automatic, and then repeat the above step 6. ...
