Nowadays, with the emergence of robot welding, it has driven the rapid development of the whole welding market. The advantages of robot welding are very obvious. It is obvious that the welding efficiency of robot welding is higher, and robot welding saves labor force and promotes the accuracy of welding work. Now many welding manufacturers begin to apply robot welding, but for welding robots, Do you really understand?
The requirement of spot welding for robot is not very high. Because spot welding only needs point position control, there is no strict requirement for the moving track of welding tongs between points, which is the reason why robots can only be used for spot welding at the beginning.
The welding robot should not only have enough load capacity, but also move quickly, smoothly and accurately between points, so as to reduce the time of displacement and improve work efficiency.
The load capacity of spot welding robot depends on the type of welding tongs used. For the welding tongs separated from the transformer, a robot with a load of 30-45kg is enough. However, on the one hand, because of the length of the secondary cable and the large power loss, it is not conducive for the robot to extend the welding tongs into the workpiece for welding; On the other hand, the cable keeps swinging with the movement of the robot, and the cable is damaged quickly.
Therefore, the use of integrated welding tongs is gradually increasing. The weight of the welding tongs and transformer is about 70kg. Considering that the robot should have enough load capacity and be able to send the welding tongs to the space position for welding with large acceleration, generally 100-150kg heavy-duty robot is selected. In order to adapt to the requirements of short distance and rapid displacement of welding tongs in continuous spot welding. The new heavy-duty robot can complete 50 mm displacement in 0.3 seconds. This puts forward higher requirements for the performance of the motor, the operation speed and algorithm of the microcomputer.
The above is a detailed introduction of the welding robot, I do not know if you have a deeper understanding of the robot after reading the above? With the wide application of near end time robots, more and more people begin to pay attention to the development trend of robots. Robots need to go to regular manufacturers to buy, which can not only provide high quality products, but also provide good after-sales service.
