Description

Technical Field

[0001] This invention relates to the field of welding equipment technology, and in particular to an intelligent welding device that requires no testing, no programming, and is designed for use without the need for instruction or programming. Background Technology

[0002] The core of intelligent welding equipment lies in eliminating the dependence of traditional welding on skilled technicians. The vision system scans the workpiece in real time, automatically identifies the position and shape of the weld, and replaces manual teaching. The built-in process expert database automatically matches welding parameters and paths based on the identification results, eliminating the need for programming. The multi-axis collaborative control system enables precise movement of complex trajectories, and the repeatability accuracy meets the requirements of industrial welding. Operators only need to select the workpiece type or confirm the identification results, and the equipment can complete the positioning, fixing, and welding operations. The equipment takes into account both safety and flexibility, adopts explosion-proof electrical design and multiple safety circuits, adapts to welding fume and spark environments, and supports automatic, semi-automatic, and manual modes, facilitating abnormal handling and debugging.

[0003] While existing intelligent welding equipment that requires no testing or programming has automated the welding process, it still has significant limitations in the workpiece preparation stage. Current equipment typically requires workers to pre-weld the accessories to the main component and fix them in place before starting the automatic welding program. This fails to achieve full automation from positioning to fixing, which means that the production line still needs to be equipped with professional welders for the initial positioning work, increasing labor costs and skill dependence.

[0004] Therefore, a self-contained intelligent welding device that requires no testing, no programming, and no instruction is proposed to solve the problems of precise positioning and spot welding fixation. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of the prior art by proposing a hands-on intelligent welding device that requires no testing, no programming, and no instruction.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a self-contained intelligent welding device that requires no testing, no programming, and includes a track, a workpiece, and welding accessories. A horizontally self-propelled truss is provided on the track, and a vertically self-propelled robotic arm is provided on the truss. A welding torch is provided at the end of the robotic arm. The robotic arm is used to drive the welding torch to move and rotate, thereby changing the welding position and angle. A rotating frame is provided at the end of the robotic arm, and a fixed frame is fixedly connected through the rotating frame. A telescopic rod is slidably connected to the inner side of the fixed frame. A support column is fixedly connected to the bottom of the telescopic rod, and an electromagnet is fixedly connected to the bottom of the support column. A magnetic block is attracted to the inner bottom of the workpiece. A fixed block is fixedly connected to the side wall of the magnetic block, and a limit switch is fixedly connected to the side wall of the fixed block. A top block is fixedly connected to the top of the electromagnet, and a touch rod for touching the limit switch is fixedly connected to the side wall of the top block. The welding accessories are attracted to the side wall of the electromagnet. A material-retrieving mechanism for automatically removing the fixed block is also provided.

[0007] In the above technical solution, a side rod is slidably connected through the side wall of the electromagnet, a side touch sensor is fixedly connected to the side wall of the side rod, a lower rod is fixedly connected to the bottom of the electromagnet, and a lower touch sensor is fixedly connected to the bottom of the lower rod. The side touch sensor and the lower touch sensor are electrically connected to the robotic arm through the controller. When the welding accessory is attracted to the electromagnet, the side wall and bottom of the welding accessory are respectively flush with the side wall of the side touch sensor and the bottom of the lower touch sensor.

[0008] In the above technical solution, the bottom end of the electromagnet is further fixedly connected with an upper screw, and the top end of the upper screw abuts against the bottom end of the side rod.

[0009] In the above technical solution, the material picking mechanism further includes a material picking rod, which is fixedly connected to the bottom end of the contact rod. A slot is opened through the top of the fixed block, and horizontal grooves are opened on both sides of the slot. T-shaped blocks are slidably connected to the inner side of the horizontal grooves. The tops of the T-shaped blocks on the adjacent sides are inclined. A pair of return springs are fixedly connected between the inner side of the horizontal groove and the side wall of the T-shaped block. A retaining ring groove is opened on the outer wall of the material picking rod.

[0010] In the above technical solution, the bottom end of the picking rod is further provided as a smooth arc surface, the width of the transverse groove is greater than the diameter of the picking rod, and the T-shaped blocks are all fixedly connected to the opposite side with a pull rod, and the pull rod is provided through the outer wall of the fixed block.

[0011] In the above technical solution, the magnet block is further provided with a spacer plate on its side wall. The spacer plate is made of plastic. When installing the fixing block and the magnet block, the spacer plate is placed on the side wall of the welding accessory at the designated installation position on the workpiece. Then, the fixing block and the magnet block are horizontally adsorbed on the bottom of the inner side of the workpiece, and the side wall of the fixing block is attached to the side of the spacer plate away from the installation position of the welding accessory, so that the fixing block can be positioned.

[0012] In the above technical solution, the end of the robotic arm is fixedly connected to a rotary motor, the side wall of the rotating frame is fixedly connected to the output end of the rotary motor, and the rotary motor is electrically connected to the controller through wires.

[0013] In the above technical solution, a lower screw is threadedly connected to the top of the fixed frame, the bottom end of the lower screw abuts against the top of the telescopic rod, and a scale groove is provided at the top of the telescopic rod.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This invention, through the setting of structures such as fixing blocks, limit switches and electromagnets, allows the welding accessories to be automatically positioned and placed on the workpiece for spot welding by simply placing the fixing blocks in the designated position and positioning and adsorbing them on the electromagnet. This eliminates the need for manual positioning and welding, improving the convenience of the device. Moreover, when welding a large number of welding accessories, multiple fixing blocks can be sequentially adsorbed on the designated position on the workpiece for spot welding one by one, greatly improving the welding efficiency of the device.

[0016] 2. By setting up a material handling mechanism, the present invention can automatically remove the fixing block from the workpiece after the welding of the welding accessories is completed, so as to avoid affecting the subsequent full welding of the welding accessories and further improve the convenience of the device.

Detailed Implementation

[0030] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.

[0032] In practical use, it was found that although the existing intelligent welding equipment that does not require testing or programming has achieved automation of the welding process, there are still obvious limitations in the part preparation stage. The current equipment usually requires workers to pre-weld the welding attachment 28 to the workpiece 10 to fix it, and the automatic welding program can only be started after the positioning is completed. It fails to achieve full automation from positioning to fixing. This defect means that the production line still needs to be equipped with professional welders to perform the pre-positioning work, which increases labor costs and skill dependence. In order to solve the above problems, the following structure is invented.

[0033] like Figures 1-12 The illustrated intelligent welding equipment, which requires no testing, teaching, or programming, includes a track 1, a workpiece 10, and welding accessories 28. A horizontally self-propelled truss 2 is mounted on the track 1, and a vertically self-propelled robotic arm 3 is mounted on the truss 2. A welding torch 4 is located at the end of the robotic arm 3. The robotic arm 3 drives the welding torch 4 to move and rotate, thereby changing the welding position and angle. The truss 2 is mounted on the track 1 and achieves a wide range of position adjustments by driving wheel sets to move along the track 1. The truss 2's uprights are equipped with a lifting mechanism, which can drive the horizontal arm and the end robotic arm 3 to move vertically, expanding the welding height range. The robotic arm 3 performs multi-degree-of-freedom precision movements at the end of the truss 2. These three components work together to achieve full coverage of the welding space. The motors driving the linkage mechanisms of each joint of the robotic arm 3 are linked, driving the end welding torch 4 to rotate and swing in multiple degrees of freedom, precisely adjusting the welding posture and angle. The coordinated movement of the robotic arm and joints completes the automated welding operation of complex welds.

[0034] The end of the robotic arm 3 is equipped with a rotating frame 5, through which a fixed frame 6 is fixedly connected. A telescopic rod 7 is slidably connected to the inside of the fixed frame 6. A support column 8 is fixedly connected to the bottom of the telescopic rod 7. An electromagnet 9 is fixedly connected to the bottom of the support column 8. A magnet block 11 is attracted to the bottom of the inside of the workpiece 10. A fixed block 12 is fixedly connected to the side wall of the magnet block 11. A limit switch 13 is fixedly connected to the side wall of the fixed block 12. A top block 14 is fixedly connected to the top of the electromagnet 9. A touch rod 15 for touching the limit switch 13 is fixedly connected to the side wall of the top block 14. A welding accessory 28 is attracted to the side wall of the electromagnet 9. A material picking mechanism for automatically removing the fixed block 12 is also provided.

[0035] A side rod 16 is slidably connected through the side wall of the electromagnet 9. A side touch sensor 17 is fixedly connected to the side wall of the side rod 16. A lower rod 32 is fixedly connected to the bottom of the electromagnet 9. A lower touch sensor 18 is fixedly connected to the bottom of the lower rod 32. Both the side touch sensor 17 and the lower touch sensor 18 are electrically connected to the robotic arm 3 through the controller. When the welding attachment 28 is attracted to the electromagnet 9, the side wall and bottom of the welding attachment 28 are aligned with the side wall of the side touch sensor 17 and the bottom of the lower touch sensor 18, respectively. By setting the side touch sensor 17 and the lower touch sensor 18, the welding attachment 28 can be accurately placed inside and at the bottom of the workpiece 10 after the electromagnet 9 reaches the designated position.

[0036] An upper screw 19 is fixedly connected to the bottom end of the electromagnet 9. The top of the upper screw 19 abuts against the bottom end of the side rod 16. Since the side rod 16 is horizontally mounted on the electromagnet 9, the upper screw 19 is unscrewed to release the pressure on the side rod 16, thereby pressing and sliding the side rod 16 and adjusting the extension length of the side rod 16. This allows for flexible adjustment of the position of the side touch sensor 17 according to the size of different workpieces 10, thus improving the applicability of the device.

[0037] The magnet block 11 has a partition plate 27 on its side wall. The partition plate 27 is made of plastic. When installing the fixing block 12 and the magnet block 11, the partition plate 27 is placed on the side wall of the welding accessory 28 at the designated installation position on the workpiece 10. Then, the fixing block 12 and the magnet block 11 are horizontally adsorbed on the bottom inner side of the workpiece 10, and the side wall of the fixing block 12 is attached to the side of the partition plate 27 away from the installation position of the welding accessory 28. The fixing block 12 can be positioned and placed. The partition plate 27 makes it easy to quickly place the fixing block 12 at a fixed distance after finding the placement position of the welding accessory 28, thus improving the convenience of the device.

[0038] When welding workpiece 10, first place workpiece 10 on the welding platform below robotic arm 3, then measure the installation position of welding attachment 28 on workpiece 10, and use spacer plate 27 to attach magnet block 11 on fixing block 12 to workpiece 10 (the side wall of magnet block 11 needs to be attached to the side of spacer plate 27 away from the placement position of welding attachment 28, and spacer plate 27 needs to be flush with the welding position of welding attachment 28, so fixation block 12 is placed at a fixed distance on the side wall of workpiece 10, and magnet block 11 needs to be attached to the bottom end of side wall of workpiece 10). If there are multiple welding positions of welding attachment 28, the above operation can be repeated, and multiple fixing blocks 12 can be installed at the same time.

[0039] Then, place the welding attachment 28 on the side wall of the electromagnet 9, energize the electromagnet 9, and fix the welding attachment 28 in place (it should be noted that this welding wall is suitable for welding materials that can be attracted by magnetic force), and align the side wall of the welding attachment 28 with the side wall of the side touch sensor 17, while aligning the bottom of the welding attachment 28 with the bottom of the lower touch sensor 18 (an L-shaped alignment plate can be used to quickly align the position of the welding attachment 28. By attaching the L-shaped alignment plate to the side touch sensor 17 and the lower touch sensor 18, and then placing the welding attachment 28 on the side wall of the electromagnet 9 and fitting it against the inner side of the L-shaped alignment plate, the alignment can be quickly achieved).

[0040] Then, the robotic arm 3 and gantry 2 can be started. (It should be noted that the robotic arm 3 is a teaching-free and programming-free intelligent welding arm. The robotic arm 3 achieves autonomous operation through an integrated 3D vision scanning system. Before welding, a laser scanning sensor or structured light camera performs an all-round scan of the weld seam of the workpiece 10, acquiring the 3D point cloud data of the weld seam in real time. The built-in intelligent algorithm automatically identifies the weld seam type, location, bevel size, and welding sequence, generating the optimal welding path and process parameters without manual teaching or offline programming. During the welding process, the vision system continuously monitors the state of the molten pool and the weld seam formation. Through the force control sensor, it senses the contact force feedback and adjusts the welding torch 4 posture, wire feed speed, and welding current in real time to achieve weld seam tracking and...) (Quality adaptive control), therefore, before welding, the position and size of the workpiece 10 are first located by integrated three-dimensional vision scanning. Then, the robotic arm 3 automatically moves the welding attachment 28 on the workpiece 10, and the side wall and bottom of the welding attachment 28 do not contact the inside of the workpiece 10. Then, when the touch rod 15 touches the limit switch 13, the limit switch 13 will transmit a signal to the controller, and the controller will control the truss 2 to stop running. (It should be noted that when the touch rod 15 touches the limit switch 13, the fixing block 12 is attracted and fixed to the workpiece 10 by the magnet block 11. The attraction force of the magnet block 11 is greater than the pushing force of the touch rod 15 to push the limit switch 13, so the fixing block 12 will not be displaced.)

[0041] The controller then controls the robotic arm 3 to move laterally on the truss 2 until the side contact sensor 17 contacts the inside of the workpiece 10, transmitting a signal to the controller. The controller then controls the robotic arm 3 to stop moving laterally, meaning the side wall of the welding attachment 28 is in contact with the inside of the workpiece 10. The controller then controls the truss 2 to move downwards, thereby driving the electromagnet 9 to move downwards until the bottom contact sensor 18 contacts the bottom of the workpiece 10, meaning the welding attachment 28 is completely placed on the workpiece 10 at the designated position. At this point, the controller can start the welding torch 4 to spot weld the welding attachment 28 onto the workpiece 10. Finally, the controller can de-energize the electromagnet 9.

[0042] In summary, with the above structural design, the welding attachment 28 can be automatically positioned and placed on the workpiece 10 for spot welding simply by placing the fixing block 12 at the designated position and positioning and adsorbing it onto the electromagnet 9. This eliminates the need for manual positioning and welding, improving the convenience of the device. Furthermore, when welding a large number of welding attachments 28, multiple fixing blocks 12 can be sequentially adsorbed onto the designated positions on the workpiece 10 for spot welding, greatly improving the welding efficiency of the device.

[0043] Based on the above embodiments, it was found during use that the above structure cannot automatically remove the fixing block 12 after the spot welding of the welding attachment 28 is completed. As a result, when the welding attachment 28 is fully welded in the future, the fixing block 12 will hinder the full welding of the welding attachment 28. Moreover, after the welding is completed, the worker still needs to remove the fixing block 12, which is quite troublesome. In order to solve the above problems, the above structure has been further improved.

[0044] The material handling mechanism includes a material handling rod 20, which is fixedly connected to the bottom end of the contact rod 15. A slot 21 is provided through the top of the fixing block 12. Horizontal grooves 22 are provided on both sides of the slot 21. T-shaped blocks 23 are slidably connected to the inner side of each horizontal groove 22. The tops of the T-shaped blocks 23 on the adjacent side are inclined. A pair of return springs 24 are fixedly connected between the inner side of the horizontal groove 22 and the side wall of the T-shaped blocks 23. A retaining ring groove 25 is provided on the outer wall of the material handling rod 20.

[0045] The bottom end of the picking rod 20 is set as a smooth arc surface, which facilitates the pressing of the inclined surface of the T-block 23 and ensures the normal insertion of the picking rod 20. The width of the transverse groove 22 is greater than the diameter of the picking rod 20. Each side of the T-block 23 is fixedly connected with a pull rod 26, and the pull rod 26 is set through the outer wall of the fixed block 12.

[0046] A rotary motor 29 is fixedly connected to the end of the robotic arm 3. The side wall of the rotating frame 5 is fixedly connected to the output end of the rotary motor 29. The rotary motor 29 is electrically connected to the controller through wires. By setting the rotary motor 29, after the welding of the welding accessory 28 is completed, the power supply of the electromagnet 9 is disconnected, and the electromagnet 9 and the fixing block 12 are taken away from the welding accessory 28 together, so as to avoid affecting the overall welding position of the welding accessory 28 in the future.

[0047] The top of the fixed frame 6 is threaded with a lower screw 30, the bottom of which abuts against the top of the telescopic rod 7. The top of the telescopic rod 7 has a scale groove 31. By setting the lower screw 30, when welding different subsequent welding accessories 28, the pressure on the telescopic rod 7 can be released by unscrewing the lower screw 30, and the telescopic rod 7 can be slid to adjust the position of the telescopic rod 7, the support column 8 and the electromagnet 9, thereby ensuring the distance between the welding torch 4 and the welding accessory 28, and ensuring that the welding torch 4 can be properly spot welded and fixed. Since the distance between the welding torch 4 and the electromagnet 9 is fixed, when the thickness of the welding accessory 28 changes, the position of the electromagnet 9 needs to be adjusted to ensure that the welding torch 4 can be properly spot welded. (It should be noted that due to the change in the thickness of the welding accessory 28, the corresponding distance when placing the fixing block 12 will also change. Therefore, when the thickness of the welding accessory 28 changes, the fixing block 12 installed through the spacer plate 27 will not affect the normal insertion of the subsequent material picking rod 20.)

[0048] During the lateral movement of the robotic arm 3 to align with the welding attachment 28, the material picking rod 20 will move on the fixed block 12 (and at this time, the material picking rod 20 is directly above the slot 21. Since the position of the contact rod 15 touching the limit switch 13 is fixed, and the distance between the fixed block 12 and the installation position of the welding attachment 28 is fixed, it can be ensured that the material picking rod 20 is above the slot 21). Then, when the truss 2 descends, the material picking rod 20 will be inserted into the slot 21. At this time, the arc surface at the bottom of the material picking rod 20 will press the inclined surface at the top of the T-block 23, thereby pushing the T-block 23 to slide in the transverse groove 22 and compressing the return spring 24 until the retaining ring groove 25 moves to the position next to the T-block 23, that is, the compression of the T-block 23 is released. Then, under the elastic force of the return spring 24, the T-block 23 is pushed to return, so that the T-block 23 is inserted into the retaining ring groove 25, and at this time, the bottom end of the welding attachment 28 is in contact with the bottom end of the workpiece 10.

[0049] After spot welding of welding accessory 28 is completed, the electromagnet 9 can be de-energized, and the rotary motor 29 can be started to drive the rotating frame 5 to rotate upward. At this time, the electromagnet 9 will be flipped upward through the support column 8, and the fixed block 12 will be pulled out of the workpiece 10 through the contact rod 15 and the picking rod 20. Then the robotic arm 3 can perform full welding on welding accessory 28. Finally, after welding is completed, the worker pulls the pull rods 26 on both sides to slide the T-block 23 to both sides and pull it out from the retaining ring groove 25, which can release the limitation on the fixed block 12. Then the fixed block 12 is removed, and a new welding accessory 28 is installed at the same time. The above operation can be repeated to continue welding.

[0050] In summary, through the design of the above structure, the fixing block 12 can be automatically removed from the workpiece 10 after the welding accessory 28 is completed, so as to avoid affecting the subsequent full welding of the welding accessory 28 and further improve the convenience of the device.

[0051] The foregoing has shown and described the basic principles, main features, and advantages of the present invention.

[0052] Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of the present invention. Various changes and modifications can be made to the present invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
