Description

Technical Field

[0001] The present invention relates to the technical field of metal welding, and in particular to a robot system and a construction method for true and false electrode butt welding. Background Art

[0002] With the continuous development of my country's industry and science and technology, my country's steelmaking technology is also gradually improving. As a result, industrial automation is gradually being realized in steelmaking workplaces. More and more advanced technologies are being applied in steelmaking scenarios, and the auxiliary work combined with them is also gradually developing towards automation. More and more automated products are replacing the original manual operations.

[0003] In the steelmaking industry, electrode butt welding is a job with a very large welding workload. Not only do the true and false electrodes need to be aligned and coaxial, but they also need to be fixed before welding. In the entire process operation, the existing technology generally adopts manual operation and welding. Manual operation needs to withstand long-term welding operations, high-temperature radiation, high labor intensity, and low efficiency. Therefore, the present invention proposes a robot system and construction method for true and false electrode butt welding to solve the problems existing in the existing technology. Summary of the Invention

[0004] In response to the above problems, the present invention proposes a robot system and construction method for true and false electrode butt welding, which solves the problems of high manual labor intensity, poor welding quality and low welding efficiency in the prior art.

[0005] To achieve the objectives of the present invention, the present invention is implemented through the following technical solutions: a robot system for welding true and false electrodes, comprising a robot walking rail, a welding robot system, a true electrode centering system, a false electrode centering system, a centering system fixing frame, a fixing frame walking mechanism, and an intelligent control system, wherein the robot walking rail is used to carry the welding robot system for walking, the centering system fixing frame is used to carry the true electrode centering system and the false electrode centering system, the true electrode centering system is used to position, clamp, and center the true electrode, the false electrode centering system is used to position, clamp, and ensure coaxiality error with the true electrode, and the welding robot system is used to weld the aligned true and false electrodes;

[0006] The fixed frame walking mechanism is used to change the position of the fixed frame of the centering system to adapt to electrodes of different diameters, and the intelligent control system is used to coordinate and control the actions of the entire system.

[0007] A further improvement is that the robot walking rail is coordinated with the welding robot system to control the walking position of the welding robot system and to control the welding robot system to stop at a safe position when the electrode is hoisted.

[0008] A further improvement is that: the welding robot system is provided with at least two groups, and the two groups of welding robot systems synchronously weld the paired true and false electrodes. The welding robot system includes a welding power supply, a wire feeding mechanism, a welding gun and an anti-collision sensor, a welding robot body, a communication cable, a robot control cabinet and a robot teaching pendant.

[0009] A further improvement is that the true electrode centering system is used to center the true electrode. When the true electrode is hoisted above the pit, the true electrode centering system adjusts the centering block to a size suitable for the electrode diameter from the front and rear directions through the adjustment function of the screw. At this time, the centering system fixing frame is pulled by the fixing frame walking mechanism to clamp in the relative direction, clamping the true electrode from the left and right directions.

[0010] Further improvements are: the centering system fixing frame is located on the ground track, and the centering system fixing frame is used to fix and adjust the real electrode centering system and the fake electrode centering system, the fixing frame walking mechanism is used to carry the centering system fixing frame, and change the left and right end distance of the centering system fixing frame through screw adjustment to clamp the electrodes in relative directions.

[0011] A further improvement is that the dummy electrode centering system is used to center the dummy electrode. After the centering and fixing of the real electrode is completed, the dummy electrode is hoisted above the real electrode. The dummy electrode centering system clamps and centers the dummy electrode from the front and back directions through the centering block and is coaxial with the real electrode.

[0012] A further improvement is that the intelligent control system has a built-in control and coordination program module, and the control and coordination program module is used to coordinate and control various structures of the system to achieve butt welding of electrodes.

[0013] A construction method of a robot system for real and fake electrode butt welding, comprising the following steps:

[0014] Step 1: The operator hoists the real electrode to the real electrode alignment system according to the requirements of the electrode welding work, and fixes the real electrode with the alignment system fixing frame;

[0015] Step 2: Lift the dummy electrode to the dummy electrode centering system and fix it to be coaxial with the real electrode;

[0016] Step 3: The welding robot system moves on the robot's walking rails and welds the aligned electrodes;

[0017] Step 4: After welding is completed, the electrode is hoisted and fixed, and the fixed frame walking mechanism separates the two ends of the centering system fixed frame in both directions. The electrode welding is completed and the finished parts are put into storage.

[0018] Further improvements are: the welding robot system welds the electrodes by cooperating with the robot's walking rail. The welding robot system has contact positioning and multi-layer multi-pass welding functions. When the electrode group is aligned, the welding robot system uses the contact positioning function to find the welding arc starting position to start welding, and uses the multi-layer multi-pass welding function to cooperate with the welding program to realize the welding of the weld position.

[0019] A further improvement is that during the welding process, an intelligent control system is used to coordinate and control the various actions of the welding robot system.

[0020] The beneficial effects of the present invention are:

[0021] 1. The present invention fixes the real electrode through the real electrode centering system, fixes the dummy electrode through the dummy electrode centering system, and moves the welding robot system on the robot's walking rail to weld the aligned electrodes. The intelligent control system is used to coordinate and control each action of the welding robot system, and the application is automated, which changes the original operation mode, reduces manual labor intensity, and improves welding quality and welding efficiency.

[0022] 2. The present invention utilizes the adjustment function of the true electrode centering system to adjust the centering block to a size suitable for the diameter of the true electrode from the front-to-back direction, and cooperates with the left and right ends of the centering system fixing frame to move in relative directions to clamp the true electrode. Then, the centering block of the false electrode centering system is used to clamp and center the false electrode from the front-to-back direction, and is coaxial with the true electrode, so that the fixation of the true and false electrodes is more stable and accurate, thereby ensuring the subsequent welding quality.

The examples are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention. Example

[0028] according to Figure 1 、 2As shown, this embodiment proposes a robot system for true and false electrode butt welding, including a robot walking rail 1, a welding robot system 2, a true electrode centering system 3, a false electrode centering system 4, a centering system fixing frame 5, a fixing frame walking mechanism 6, and an intelligent control system 7. The robot walking rail 1 is used to carry the welding robot system 2 for walking, the centering system fixing frame 5 is used to carry the true electrode centering system 3 and the false electrode centering system 4, the true electrode centering system 3 is used to position, clamp and center the true electrode, the false electrode centering system 4 is used to position, clamp and ensure the coaxial error of the false electrode, and the welding robot system 2 is used to weld the aligned true and false electrodes;

[0029] The fixed frame travel mechanism 6 is used to change the position of the centering system fixed frame 5 to accommodate electrodes of different diameters, and the intelligent control system 7 is used to coordinate and control the movements of the entire system. The present invention uses the real electrode centering system 3 to secure the real electrode, the dummy electrode centering system 4 to secure the dummy electrode, and the welding robot system 2 to move on the robot travel rail 1 to weld the aligned electrodes. The intelligent control system 7 coordinates and controls the various movements of the welding robot system 2, automating the application, changing the original operating method, reducing manual labor intensity, and improving welding quality and efficiency.

[0030] The robot walking rail 1 coordinates with the welding robot system 2 to control the walking position of the welding robot system 2 and to control the welding robot system 2 to stop at a safe position when the electrode is hoisted. This ensures the accuracy of the robot's walking position and allows it to stop at a safe position when the electrode is hoisted.

[0031] The welding robot system 2 is provided with at least two groups, and the two groups of welding robot systems 2 synchronously weld the matched true and false electrodes. The welding robot system 2 includes a welding power supply, a wire feeding mechanism, a welding gun and an anti-collision sensor, a welding robot body, a communication cable, a robot control cabinet and a robot teaching pendant.

[0032] The real electrode centering system 3 is used to center the real electrode. When the real electrode is hoisted above the pit, the real electrode centering system 3 uses the screw adjustment function to adjust the centering block in the front-to-back direction to a size that suits the electrode diameter. At this time, the centering system fixing frame 5, pulled by the fixing frame travel mechanism 6, clamps the real electrode in opposite directions, clamping it from the left and right. At this point, the hoisting process is completed, and the real electrode is fixed.

[0033] The centering system mounting frame 5 is located on a ground track and is used to secure and adjust the true electrode centering system 3 and the dummy electrode centering system 4. The mounting frame travel mechanism 6 supports the centering system mounting frame 5 and adjusts the distance between the left and right ends of the mounting frame 5 via a lead screw to clamp the electrodes in relative directions. This ensures more stable and accurate electrode fixation, ensuring subsequent welding quality.

[0034] The dummy electrode centering system 4 is used to center the dummy electrode. Once the real electrode is centered and secured, the dummy electrode is hoisted above the real electrode. The dummy electrode centering system 4 clamps the dummy electrode from the front and back using the centering block, aligning it coaxially with the real electrode. This ensures more stable and accurate fixation of the real and dummy electrodes, ensuring subsequent welding quality.

[0035] The intelligent control system 7 has a built-in control and coordination program module, which is used to coordinate and control the various structures of the system to achieve butt welding of the electrodes. When in use, the control and coordination program module performs global coordination and control. The control and coordination program module is a program module of the prior art. By writing a control program, the entire system is controlled to ensure the implementation of automated welding. Example

[0038] Step 2: Lift the dummy electrode to the dummy electrode centering system 4 for fixation, and control it to be coaxial with the real electrode; this makes the fixation of the real and dummy electrodes more stable and accurate, ensuring the subsequent welding quality;

[0039] Step 3: The welding robot system 2 moves on the robot walking rail 1 and welds the aligned electrodes; the welding robot system 2 welds the electrodes by cooperating with the robot walking rail 1. The welding robot system 2 has contact positioning and multi-layer multi-pass welding functions. When the electrode group is aligned, the welding robot system 2 uses the contact positioning function to find the welding arc starting position to start welding, and uses the multi-layer multi-pass welding function to cooperate with the welding program to achieve welding at the weld position. During the welding process, the intelligent control system 7 is used to coordinate and control the various actions of the welding robot system 2; automated application changes the original operating method, reduces manual labor intensity, and improves welding quality and welding efficiency;

[0040] Step 4: After welding is completed, the electrode is hoisted and fixed, and the fixed frame walking mechanism 6 separates the two ends of the centering system fixed frame 5 in both directions. The electrode welding is completed and the finished parts are stored. It is convenient for automatic unloading.

[0041] The present invention fixes the real electrode through the real electrode centering system 3, fixes the dummy electrode through the dummy electrode centering system 4, and moves the welding robot system 2 on the robot's walking rail 1 to weld the aligned electrodes. The intelligent control system 7 is used to coordinate and control the various actions of the welding robot system 2, automating the application, changing the original operating method, reducing manual labor intensity, and improving welding quality and efficiency. The present invention also uses the adjustment function of the real electrode centering system 3 to adjust the centering block from the front-to-back direction to a size suitable for the diameter of the real electrode, cooperates with the left and right ends of the centering system fixing frame 5 to move in relative directions, clamping the real electrode, and then uses the centering block of the dummy electrode centering system 4 to clamp and center the dummy electrode from the front-to-back direction, and coaxially with the real electrode, making the fixation of the real and dummy electrodes more stable and accurate, ensuring the subsequent welding quality.
