Welding RobotImprove Work Efficiency
The welding robot is an industrial robot engaged in welding. Industrial robots are a multi-purpose, reproducible, automated control machine with three or more programmable axes for industrial automation, according to the International Organization for Standardization of Industrial Robotics. Welding robots mainly include robots and welding equipment in two parts. The robot consists of the robot body and the control cabinet. The welding equipment, arc welding and spot welding, for example, by the welding power supply, wire feeder, welding gun and other components. For intelligent robots should also have a sensing system, such as laser or camera sensors and their control devices.
Spot welding on the welding robot requirements are not very high. Because spot welding only point control, as the welding clamp between the point and the point of the trajectory is not strictly required, which is the first robot can only be used for spot welding reasons. Spot welding robots not only have enough load capacity, but also in the point between the points when the speed to be fast, the action should be smooth, accurate positioning to reduce the time to shift
High efficiency. How much load capacity is required for spot welding robots depends on the type of welding tongs used. For robots that are separated from the transformer, 30 to 45 kg of loaded robots are sufficient. However, this welding clamp on the one hand due to the secondary cable length, power loss is not conducive to the robot will be welded into the workpiece welding welding; The Therefore, the current increase in the use of one-piece welding clamp. This kind of welding tongs together with the transformer quality is about 70kg. Taking into account the robot to have enough load capacity, with a large acceleration to the welding fixture to the location of the welding, are generally selected 100 ~ 150kg load heavy-duty robot. In order to meet the continuous spot welding welding clamp short distance rapid shift requirements. The new heavy-duty robot has been able to complete the 50mm displacement function within 0.3s. This is the performance of the motor, the computer's speed and algorithm are put forward higher requirements.
Welding robot production line is relatively simple to multiple workstations (units) with the workpiece conveyor line connected to form a production line. This line still maintains the characteristics of a single station, that is, each station can only use the selected workpiece fixture and welding robot program to weld the intended workpiece, in the change fixture and procedures for some time, this line is not welding Other artifacts.
