What points do you need to pay attention to when using welding robots?
1. It is necessary to teach the robot before active welding, and it is necessary for the operator to teach the track of the robot welding gun and set the welding conditions. Because it is necessary to teach, the robot does not weld a wide range of products produced in small quantities.
2. It is necessary to ensure the accuracy of the workpiece, the robot has no eyes and can only repeat the same action. The robot track accuracy is ±0.1mm, and the same action is repeated with this accuracy. When the welding error is greater than the radius of the welding wire, it is possible that the welding is not good, so the accuracy of the workpiece should be kept within the radius of the welding wire.
3. The setting of welding conditions depends on the technical level of the operator, and it is necessary for the operator to enter the welding program, welding torch attitude and viewpoint, current, voltage, speed and other welding conditions when the operator teaches. It is necessary to teach the operator to have sufficient welding knowledge and welding skills.
4. It is necessary to pay full attention to the safety robot is a high-speed motion equipment, and people are definitely not allowed to approach the robot when it is actively running (it is necessary to set up safety guardrails). It is necessary for operators to receive special education in occupational safety, otherwise they are forbidden to operate.
The industrial robots in the welding operation require us to have the necessary knowledge:
1. The weld should be cleaned and clean, free of oil, rust, welding slag, slag cutting and other sundries, and weldable primer is allowed. Otherwise, the success rate of arc striking will be affected. Positioning welding is changed from electrode welding to gas maintenance welding, and the spot welding parts are polished together to avoid the slag shell or porosity left by positioning welding, and then avoid the instability of the arc and even the generation of spatter. The installation fixture with high precision is used to improve the installation accuracy of the weldment.
2. It is necessary to have good consistency in the installation quality and accuracy of the workpiece. The use of welding robots should strictly control the preparation quality of parts and improve the installation accuracy of weldments. The surface quality of the part, the size of the groove and the installation accuracy will affect the weld tracking effect. It can compile a special welding process for welding robots, and carry out strict process rules for part scale, weld groove and installation scale.
3. The general parts and groove scale are controlled at ±0.8mm, and the installation scale error is controlled within ±1.5mm, and the probability of welding defects such as porosity and undercut in the weld can be greatly reduced. to improve the quality of part preparation and the accuracy of weldment installation.

Estun servo motor - how to choose a servo motor?
The selection of servo motor is not only affected by the weight of the mechanism, but also the movement conditions of the equipment will also change the selection of servo motor. The greater the inertia, the greater the acceleration and deceleration torque, and the shorter the acceleration and deceleration time, the greater the output torque of the servo motor. When choosing a servo motor specification, follow the steps below.

Estun servo motor - how to accurately control the torque of synchronous motor?
1. The electromagnetic torque of the synchronous motor is the interaction between the rotating magnetic field of the stator generated by the power supply voltage and the main magnetic field of the rotor;
2. The intersection angle of the magnetic pole axis of the rotating magnetic field of the stator and the main magnetic field of the rotor is called the work angle;
3. When the power angle is zero, the electromagnetic torque is zero, and the work is zero.
