1. Welding speed. Welding speed needs to match the welding quality, if the welding speed is too fast, it will affect the welding quality, easy to appear welding deviation, less welding, missing welding and other welding defects, the welding speed is too slow, it will affect the product production process, welding speed is an important indicator to determine the welding efficiency. ...

1. The battery of the data storage on the robot encoder is not electric or has been damaged and disassembled, and the battery installation box of the pulse data storage of the encoder is disassembled, and the voltage of each battery of the battery box is measured, which is below 1.4V, and the battery voltage is obviously low. ...

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. Fault phenomenon: The robot is out of control, the welding tong collides with the fixture and the six axes inserted into the fixture continue to rotate, resulting in the deformation of the welding tong and the oil leakage at the flange at the end of the six axes and the reducer. 2. Preliminary prediction of the cause of the failure: (1) The end flange or reducer is damaged. ...

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). ...

1. High work efficiency The column robot palletizer grabs 300-400 times per hour, and you can choose between single and double claw hands, and the speed and quality are much higher than manual labor. 2. High operation accuracy and large working range. The column robot palletizer occupies a small area, and the action ...

1) The positioning accuracy of the parts is higher, and the relative position accuracy of the weld is higher, which should be ≤ 1mm. 2) Because the weldments are generally welded by a plurality of simple parts grouped, and the assembly and positioning welding of these parts are carried out in order on the welding fixture, therefore, their positioning and ...

1. Man-made faults caused by improper operation mainly include damage to the welding torch of the welding robot and improper loading and unloading of the workpiece, which causes the positioner to be deformed with the movement. 2. Faults caused by poor design and manufacturing of peripheral equipment, mainly including: lifting platform switch and cable problems, teaching pendant display part of the components...

1. Programming work: Technicians need to program the welding robot, construct the motion trajectory and welding torch attitude in the programming software, set the welding point according to the drawings of the workpiece, and input it into the control system after programming for operation. 2. Boot operation, ...

Welding robots are industrial robots engaged in welding, cutting and spraying. The welding robot mainly includes two parts: the robot and the welding equipment. The robot consists of a robot body and a control cabinet (hardware and software). The welding equipment, taking arc welding and spot welding as an example, is powered by welding, (including ...

Basic functions The arc welding process is much more complex than the spot welding process, and the tool center point (TCP), that is, the movement trajectory of the wire end, the attitude of the welding gun, and the welding parameters all require precise control. Therefore, in addition to the general functions described above, the arc welding robot must also have a ...

Effect of changes in electrical parameters of welding on the quality of welding: 1. Welding current When the welding current increases (other conditions remain unchanged), the penetration depth and residual height of the weld increase, and the melting width remains unchanged (or slightly increases) for the following reasons: (1) When the current increases, the arc on the workpiece ...

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) lubricate each axis of the robot; 2) red grease nipples on RP positioners and RTS tracks with butter; 3) The blue oil nozzle on the RP positioner with gray conductive grease; 4) Feed the needle roller bearing with lubricating oil (a small amount of butter is sufficient); 5) Clean up the gun ...

1. Number of joints. The number of joints can also be called degrees of freedom, which is an important indicator of the flexibility of the robot. Generally speaking, the robot workspace can reach three degrees of freedom, but welding not only needs to reach a certain position in the space, but also needs to ensure the spatial attitude of the welding gun. ...

1. Gas arc welding: Argon arc welding, which uses argon as the shielding gas in the welding area, and carbon dioxide shielded welding, which uses carbon dioxide as the shielding gas in the welding, are all gas-shielded arc welding. The basic principle is that when welding with an electric arc as a heat source, ...

The welding robot is composed of a robot and welding equipment, and the robot is composed of a body and a control cabinet. Welding robots can be divided into spot welding robots and arc welding robots, what is the difference between the two? Let me walk you through them: 1. The characteristics of spot welding robots

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. 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 ...
