It should be understood that the present invention can have various changes in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations therein are essentially for illustrative purposes rather than for limiting the present invention.

These descriptions are appropriate when these elements are in the positions shown in the drawings. If the descriptions of the positions of these elements change, the indications of these directions also change accordingly.

[0031] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0032] In view of the technical problems that traditional automatic welding machines and welding robots have limited application flexibility due to their fixed installation positions, making them unable to adapt to the welding needs of multiple scenes and multiple stations, resulting in low equipment utilization and inability to achieve flexible operations. This embodiment provides a welding robot system that can move between various welding stations and weld different workpieces to be welded.

[0033] See also Figures 1 to 7 In this embodiment, the welding robot system 100 includes a robot 10 and a transfer platform 20. All welding elements of the robot 10 are integrated on the transfer platform 20, and the robot 10 can follow the transfer platform 20 to move in various welding stations to weld different workpieces to be welded.

[0034] See also Figures 1 to 4 In some embodiments, the robot 10 includes a multi-axis robotic arm 11 fixed on a transfer platform 20, a control cabinet 12 electrically connected to the robotic arm 11, a welding gun 13 disposed on the robotic arm 11, a welding machine 14 connected to the welding gun 13, and an operating cabinet 15 electrically connected to the control cabinet 12 and the welding machine 14.

[0035] In some embodiments, the robot arm 11 may have multiple rotating and moving joints, which can flexibly move in multiple directions, so that the robot arm 11 can be accurately positioned and moved. The welding gun 13 is installed at the end of the robot arm 11 so as to be able to move with the movement of the robot arm 11, so that the welding gun 13 on the robot arm 11 can reach different welding positions and adapt to the welding of different workpieces to be welded.

[0036] It is conceivable that the robot arm 11 can be a five-axis or six-axis robot arm 11, which can have multiple degrees of freedom. The robot arm 11 can be set at the center of the transfer platform 20 so that the center of gravity of the entire welding robot system 100 can be located in the middle of the transfer platform 20 to prevent rollover during movement.

[0037] In some embodiments, the control cabinet 12 can be fixed on the transfer platform 20, and the control cabinet 12 is located on one side of the robot 11. A central processing unit can be set in the control cabinet 12, and the central processing unit can be electrically connected to the robot 11 so that the central processing unit can send a control signal to drive the robot 11 to move.

[0038] It should be understood that, in some other embodiments, multiple welding robot systems 100 may be provided on each assembly line. In order to prevent adjacent robots 10 from colliding and minimize the distance between two adjacent robots 10. The control cabinet 12 can accurately control the trajectory of the welding gun 13 on each robot arm 11, the sequence of movement between each joint, and the running speed, so that there is no collision or jamming when the robot 10 changes its posture. In addition, in some embodiments, the robot 10 may also have an anti-collision function, which can provide safety protection for the operator.

[0039] In some embodiments, the welder 14 can be arranged on a side of the transfer platform 20 away from the control cabinet 12, so that the robot arm 11 is located between the control cabinet 12 and the welder 14. The welder 14 can be connected to the welding gun 13 on the robot arm 11 to provide the welding gun 13 with the required welding current, welding materials and other welding parameters.

[0040] In some embodiments, the welder 14 may include a welder body. A welding power source may be provided in the welder body, and the welding power source may be connected to the welding gun 13 to provide a high voltage current to the welding gun 13. A wire feeder may also be provided in the welder body, and the wire feeder may be connected to the welding gun 13 through a wire feeding hose to provide welding materials to the welding gun 13.

[0041] In some embodiments, a processor may be provided in the welding machine body, and the processor may send a control signal to control the welding power supply and the wire feeder to work according to a predetermined program, so as to realize automatic wire feeding and automatic welding of the welding gun 13 .

[0042] In some embodiments, the operating cabinet 15 can be arranged on a side of the transfer platform 20 away from the welding gun 13, so that the user can operate the operating cabinet 15. A variety of different welding process parameters can be pre-stored in the operating cabinet 15, and the control cabinet 12 and the welding machine 14 can drive the robot arm 11 and the welding gun 13 to weld the workpiece to be welded according to the pre-stored welding process parameters.

[0043] Specifically, two operation cabinets 15 can be provided, and the two operation cabinets 15 can be electrically connected to the welding machine 14 and the control cabinet 12 respectively to separately control the welding machine 14 and the control cabinet 12. Of course, only one operation cabinet 15 can be provided, which can control the welding machine 14 and the control cabinet 12 at the same time.

[0044] In some embodiments, the welding process parameters preset in the operating cabinet 15 can correspond to various types of welds such as straight lines and arcs, and can also adapt to different types of welds such as fillet welds, butt welds, lap welds, etc.; so that the robot 10 can adapt to different workpieces to be welded.

[0045] When the user selects the corresponding welding process parameters on the operation cabinet 15 according to the type of weld of the workpiece to be welded. The operation cabinet 15 transmits the welding process parameters to the control cabinet 12 and the welding machine 14. The control cabinet 12 generates corresponding control instructions according to the welding process parameters, and drives the multi-axis robot arm 11 to move through electrical signals, so that the welding gun 13 moves to the welding position of the workpiece to be welded. At this time, the welding machine 14 also provides the welding current and welding materials required by the welding gun 13 according to the welding process parameters to start the welding operation. Under the instruction of the control cabinet 12, the robot arm 11 flexibly moves the welding gun 13 to weld different parts of the workpiece to be welded, ensuring the efficiency and accuracy of the welding process. After the welding is completed, the control cabinet 12 controls the robot arm 11 to move the welding gun 13 back to the initial position, and the welding machine 14 stops power supply and feeding to complete one welding.

[0046] Pre-storing a variety of welding process parameters can adapt to different welding requirements, allowing the robot 10 to perform welding at different workstations, improving the general efficiency of the system and achieving flexible operation. In addition, the operator can quickly select suitable welding parameters, reduce debugging time, and improve welding efficiency and quality.

[0047] See also Figures 2 to 4 In some embodiments, the robot 10 further includes a visual sensor 16 and a laser sensor 17 .

[0048] The visual sensor 16 is disposed on the transfer platform 20 and is located above the workpiece to be welded. The visual sensor 16 is electrically connected to the control cabinet 12. The visual sensor 16 can identify and scan the workpiece to be welded to generate three-dimensional model data, and transmit the three-dimensional model data to the control cabinet 12 to locate the workpiece to be welded.

[0049] The laser sensor 17 is arranged on the robot arm 11 and can move with the welding gun 13. The laser sensor 17 is electrically connected to the control cabinet 12. The laser sensor 17 is used to accurately scan the workpiece to be welded, generate welding trajectory data corresponding to the three-dimensional model, and transmit the welding trajectory data to the control cabinet 12. The control cabinet 12 drives the welding gun 13 on the robot arm 11 to move according to the welding trajectory data.

[0050] Specifically, a first connecting rod 161 is provided on the transfer platform 20, one end of which is fixed to the rear side of the transfer platform 20; the other end of the first connecting rod 161 is bent and extends above the workpiece to be welded, so as to fix the visual sensor 16, so that the visual sensor 16 can be located above the workpiece to be welded. The visual sensor 16 can roughly scan the workpiece to be welded to form basic three-dimensional model data, and transmit the basic three-dimensional model data to the control cabinet 12 for processing, so as to perform preliminary positioning of the workpiece to be welded.

[0051] The robot arm 11 is provided with a second connecting rod 171, one end of which is fixed to the end of the robot arm 11, and the other end of the second connecting rod 171 is bent and extended to the nozzle of the welding gun 13 to fix the laser sensor 17. The laser sensor 17 can move with the welding gun 13 to accurately scan the workpiece to be welded and generate detailed welding trajectory data on the three-dimensional model. The control cabinet 12 automatically generates a welding path according to the welding trajectory data generated by the laser sensor 17, and drives the welding gun 13 to weld the workpiece to be welded according to the welding path.

[0052] By combining the visual sensor 16 and the laser sensor 17, fully automated scanning, positioning, and welding of the welding operation are realized, so that the welding robot system 100 can perform welding on different workpieces to be welded and different welding stations to meet the welding needs of multiple scenarios and improve production efficiency.

[0053] See also Figures 1 to 4 In some embodiments, the robot 10 further includes a gun cleaning station 18 . The gun cleaning station 18 is disposed on the transfer platform 20 ; the robot arm 11 can drive the welding gun 13 to move into the gun cleaning station 18 , and the gun cleaning station 18 can clean and maintain the welding gun 13 .

[0054] In some embodiments, the gun cleaning station 18 can be connected to the transfer platform 20 via a vertically extending third connecting rod 181, so that the gun cleaning station 18 is fixedly set at the edge of the transfer platform 20, so that the robot arm 11 can move the welding gun 13 to the gun cleaning station 18 for cleaning.

[0055] In some embodiments, the gun cleaning station 18 may include a cleaning room for accommodating the nozzle portion of the welding gun 13. A cleaning brush may be provided in the cleaning room for mechanically cleaning the welding slag and dirt on the nozzle of the welding gun 13. A pneumatic nozzle may be provided in the cleaning room, and the pneumatic nozzle can use a high-pressure airflow to purge the welding gun 13 to remove welding slag and other impurities. A wire shear may also be provided in the cleaning room for shearing off excess welding wire on the welding gun 13 to ensure welding quality. The gun cleaning station 18 may also include a waste collection tank, which may be provided outside the cleaning room for collecting welding slag and debris generated during the cleaning process.

[0056] In some embodiments, the gun cleaning station 18 may be electrically connected to the control cabinet 12. When the welding operation is completed or the welding gun 13 needs to be cleaned, the control cabinet 12 issues a command, and the robot arm 11 moves the welding gun 13 into the cleaning room of the gun cleaning station 18. The gun cleaning station 18 starts the cleaning program to mechanically clean the welding slag and dirt on the nozzle of the welding gun 13.

[0057] See also Figure 5 and Figure 6In some embodiments, the transfer platform 20 is used to carry the robot 10, that is, the robot arm 11, the control cabinet 12, the welding machine 14 and the gun cleaning station 18 on the robot 10 can be integrated on the top surface of the transfer platform 20. The transfer platform 20 can move between different welding stations to drive the robot 10 on the transfer platform 20 to move to different welding stations to achieve welding of different workpieces to be welded, thereby improving the flexibility and efficiency of the welding operation, and improving the flexibility and production efficiency of the production line.

[0058] See also Figure 5 and Figure 6 In some embodiments, the transfer platform 20 includes a platform body 21 and a mobile transport unit. The robot 10 is fixed on the top surface of the platform body 21, and the mobile transport unit is arranged on the platform body 21. The mobile transport unit is used to connect with an external mobile device so that the external mobile device can drive the transfer platform 20 and the robot 10 to move between different welding stations.

[0059] See also Figure 5 In some embodiments, the mobile transport unit includes a lifting lug 221. The lifting lug 221 is fixed to the top surface of the platform body 21. Four lifting lugs 221 can be provided, and the four lifting lugs 221 are located at four top corners of the platform body 21. The lifting lug 221 is used to connect with a lifting device, and the lifting device can transport the transfer platform 20 and the robot 10 to the welding station.

[0060] It is conceivable that the lifting lugs 221 may also be provided at other positions of the platform body 21, and their number may also be increased or decreased, as long as the center of gravity of the welding robot system 100 is stable and does not shake when the sling is connected to the lifting lugs 221.

[0061] See also Figure 5 In some examples, the mobile transport unit may further include a slot opening 222. The slot opening 222 is fixed to the platform body 21, the slot opening 222 is located on the bottom surface of the platform body 21, and extends along the width direction of the platform body 21. The slot opening 222 is used to match a forklift, and the forklift can be inserted into the slot opening 222 to transport the transfer platform 20 and the robot 10 to the welding station. It is conceivable that two or more slot openings 222 can be provided, and multiple slot openings 222 can be symmetrically provided on both sides of the platform body 21 to prevent rollover during transportation with a forklift.

[0062] By providing the lifting lug 221 and the slot 222 on the platform body 21, the entire welding robot system 100 can be transported under different external mobile devices, and its movement mode is more flexible and changeable, and can be quickly transported to the required welding station without being affected by the site, and perform welding operations to meet the welding needs of multiple scenarios. Of course, it is conceivable that the mobile transport part can also be constructed into other shapes to cooperate with other external mobile devices for transportation, as long as it can realize the movement of the welding robot system 100.

[0063] See also Figure 5 and Figure 6 In some embodiments, a plurality of feet 211 are further provided on the bottom surface of the platform body 21 for supporting the platform body 21. Four or six feet 211 may be provided, as long as the platform body 21 can be supported. Screw holes may also be provided on the feet 211, and the screw holes may be connected to the screw holes on the welding station by bolts, so that the transfer platform 20 can be fixed on the welding station.

[0064] In some embodiments, the transfer platform 20 further includes a quick-plug interface. The quick-plug interface is provided on the platform body 21, one end of the quick-plug interface is electrically connected to the robot 10, and the other end of the quick-plug interface is used to connect to a plug on the welding station to power the robot 10.

[0065] It is conceivable that the quick-plug interface can adopt a standard charging interface, which can be quickly connected to the plug of the external power supply on the welding station. When the entire welding robot system 100 moves to different welding stations, it can be quickly connected to the external power supply. Of course, in some other embodiments, the quick-plug interface can also be set on the control cabinet 12 of the robot 10 or the welding machine 14, as long as the electrical connection between the external power supply and the robot 10 can be achieved.

[0066] See also Figures 5 to 7 In some embodiments, the transfer platform 20 further includes a plurality of leveling locking mechanisms 23; the leveling locking mechanisms 23 can be arranged at four top corners of the platform body 21, so that it can be quickly leveled at any welding station.

[0068] The locking body 231 is fixed at the top angle of the platform body 21, and the adjusting screw 232 is movably arranged on the locking body 231 and is threadedly connected with the locking body 231. When the adjusting screw 232 rotates around its own axis, the adjusting screw 232 can move up and down in a direction perpendicular to the platform body 21 to support the ground and support and level the platform body 21.

[0069] When the transfer platform 20 is moved from one welding station to another, the entire platform body 21 may be tilted due to uneven or tilted ground. At this time, the adjusting screw 232 at the lower top angle of the horizontal position can be rotated to move downward in a direction perpendicular to the platform body 21 and abut against the ground; so that the entire platform body 21 is on a horizontal plane, so that the transfer platform 20 can be quickly leveled.

[0070] See also Figure 7 In some embodiments, the leveling locking mechanism 23 further includes a support leg 233 and an abutment wheel 234, and the support leg 233 is fixed below the adjustment screw 232. The abutment wheel 234 may be cylindrical and fixed on the support leg 233 for abutment support with the ground.

[0071] The support frame 233 is used to fix the contact wheel 234 below the adjusting screw 232, and the contact wheel 234 is used to contact the ground, so that the leveling locking mechanism 23 can be used on a bumpy ground. In addition, the contact wheel 234 can also be made of materials such as rubber or silicone to increase the friction with the ground and provide a certain buffering effect.

[0072] See also Figure 7 In some embodiments, the leveling locking mechanism 23 further includes a hand wheel 235. The hand wheel 235 is disposed above the adjusting screw 232. The user can rotate the hand wheel 235 to drive the adjusting screw 232 to rotate in the locking body 231, so that the adjusting screw 232 moves in a direction perpendicular to the platform body 21, so that the adjusting screw 232 can move up and down quickly, thereby saving the user's force in rotating the adjusting screw 232.

[0073] It is conceivable that, in some other embodiments, a driving motor may be provided on the adjusting screw 232, and the adjusting screw 232 may be driven to rotate by the rotation of the driving motor, so that the adjusting screw 232 can move up and down along the internal threaded hole in the locking body 231 to achieve leveling of the platform body 21.
