I. Enhancing the precision of welding robots to ensure high-speed welding
For small and medium-sized enterprises, utilizing welding robots during the production process signifies the pursuit of high efficiency and superior welding quality.
Therefore, major welding robot manufacturers are striving to make advancements by increasing welding speed, and the high precision in trajectory control of welding robots remains a reliable guarantee for high-speed welding.
II. Dual-Robot Coordinated Welding Function
In the welding production process, we often encounter elongated workpieces, with weld seams distributed at both ends.
If one welding robot is deployed, inconsistencies in welding deformation may occur due to non-simultaneous welding at both ends, causing the workpiece to twist longitudinally and making it difficult for the welded component to meet size requirements.
For such elongated workpieces, JiuDe Company suggests that enterprises use two welding robots working in tandem, giving rise to the dual-robot coordinated welding technology. This technique is often employed in the welding processes of automobile rear axles and mufflers.
Two welding robots correspond to a welding positioner driven by an external axis of the robot.
On the longitudinally placed workpiece on the positioner, there are two mirror-symmetrical components.
Two similar circumferential weld seams require the two robots to achieve synchronized coordinated welding while the positioner rotates. This method can increase the efficiency of the welding production operation by at least double.
III. Features and Advantages of Spot Welding Robots
If small and medium-sized enterprises greatly enhance welding quality stability and efficiency using arc welding robots, then spot welding robots could be said to have even more advantages, yielding considerable economic benefits. These are primarily manifested in the following areas:
1. Spot welding robots often employ integrated tong and transformer systems, reducing the transformer’s capacity to one-third to one-quarter, saving energy and significantly easing the physical labor of the operators.
2. Spot welding robots have more control methods for the automatic switching of tong pressure and welding conditions. They can easily implement unique welding sequences for different spot locations, greatly improving spot quality while preventing issues like missed spots, multiple spots, and inaccurate positioning.
3. Spot welding robots clearly excel in spot efficiency, increasing efficiency by 8-10 times. There was a customer of JiuDe Intelligence who experienced temporary equipment failure. Due to tight deadlines, they manually spot-welded the same workpieces. The result was that four manual welding tongs could only produce 40 pieces in two shifts, while the spot welding robot could produce around 90 pieces in a single shift under normal operations.
4. Spot welding robots can utilize some unique technologies of welding robots to further precisely control the welding sequence, thereby improving welding efficiency and quality. The use of electric welding tongs on welding robots not only changes the way pressure is applied, but the advantage also lies in the robot’s control over its travel.
1. Ideal travel can be achieved based on the position of the welding point.
2. Clamp pressure can be segmentally controlled during the welding process.
3. The time nodes of welding condition output can be controlled.
4. The gap teaching function can be used to flexibly choose the teaching method of the upper electrode or the lower electrode, greatly reducing teaching time.
Of course, welding robots have many more functions that have been tested in practice, and they have brought significant effects and benefits by improving welding production efficiency and welding quality for different clients. Each welding robot manufacturer has unique features in the development of various extended functions.
It’s fair to say that in the field of welding processing, a variety of advanced technologies are constantly emerging, adding a vibrant touch to the industry.
