Description

Technical Field

[0001] This invention relates to the field of aluminum alloy mesh welding and processing, specifically to a fully automatic electric arc welding device for aluminum alloy mesh. Background Technology

[0002] Aluminum alloy mesh possesses advantages such as light weight, high strength, and excellent corrosion resistance. Its superior physical and chemical properties, as well as its processing performance, make it widely used in aerospace, automotive manufacturing, building decoration, filtration and screening, electronic shielding, and current collectors for new energy batteries. With the continuous improvement of industrial automation, the industry is placing increasingly stringent requirements on the processing precision, connection strength, and production efficiency of aluminum alloy mesh.

[0003] Among various joining processes, arc welding has become the mainstream process for connecting aluminum alloy mesh nodes due to its advantages such as sufficient penetration, high joint strength, and wide applicability. In actual production, aluminum alloy mesh needs to be assembled and fixed inside a metal frame. Currently, conventional arc welding equipment mostly uses linear continuous welding to complete the welding operation. However, due to its shape, the aluminum alloy mesh lacks flatness and cannot completely fit the inner wall of the metal frame. Therefore, during operation, it is necessary to first perform multi-point spot welding for positioning of the mesh, and manual assistance is required to press the mesh surface during the spot welding process. This not only results in poor operational safety but also makes it difficult to guarantee welding quality and joint connection strength. Summary of the Invention

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1: Please refer to Figures 1-8 The figure shows a fully automatic arc welding device for aluminum alloy mesh, including a processing platform 1 and a gantry 2 fixedly installed on the top of the processing platform 1. An electric push rod 3 is fixedly installed on the top of the gantry 2, and an installation plate 4 is fixedly installed on the bottom of the electric push rod 3. Four centrally symmetrical sliding frames 5 are provided on the bottom of the installation plate 4. A moving block 6 is provided on the inner side of the sliding frame 5, and a welder 7 is provided on the outer side of the moving block 6. The frame to be welded and the aluminum alloy mesh are placed on the processing platform 1, and the electric push rod 3 pushes the installation plate 4 downward. The installation plate 4 brings the four welders 7 close to the top of the aluminum alloy mesh, and the moving block 6 drives the welders 7 to move, welding and assembling the aluminum alloy mesh onto the frame, thereby improving welding efficiency. The mesh fixing mechanism includes pressure rollers 8 located at the bottom of the sliding frame 5. Four pressure rollers 8 can simultaneously push the top of the aluminum alloy mesh. The mesh fixing mechanism also includes a U-shaped frame 11 fixedly installed at the bottom of the mounting plate 4. The sliding frame 5 is fixedly installed at the bottom of the U-shaped frame 11. Connecting plates 12 are fixedly installed at both ends of the pressure rollers 8. An mounting rod 13 is fixedly installed at the end of the connecting plate 12 away from the pressure rollers 8. The mounting rod 13 is rotatably installed on the outside of the sliding frame 5. A sleeve 14 is fitted onto the outside of the mounting rod 13. The sleeve 14 is fixedly installed on the outside of the sliding frame 5. A coil spring 15 is fixedly installed between the inner side of the sleeve 14 and the outer side of the mounting rod 13. A limiting block 16 is fixedly installed on the outer side of the mounting rod 13. An arc-shaped groove is provided on the inner side of the sliding frame 5 for the limiting block 16 to slide within a limited range. The coil spring 15 helps the mounting rod 13 maintain its angular positioning and allows the mounting rod 13 to obliquely place the connecting plate 12 at the bottom of the slide frame 5. A screw 17 is rotatably mounted on the inner side of the slide frame 5, and a moving block 6 is threaded onto the outer side of the screw 17. A light shaft for limiting the sliding movement of the moving block 6 is fixedly mounted on the inner side of the slide frame 5. First conical wheels 18 that mesh with each other are fixedly mounted on the outer sides of adjacent screws 17. A drive motor 19 is fixedly mounted on the inner side of the return frame 11. The output end of the drive motor 19 is connected to the adjacent screw 17 via a first synchronous belt. The moving block 6 is connected to the welder 7 via an L-shaped support arm 20. The electric push rod 3 can push the mounting plate 4 downwards, causing the mounting plate 4 to move the four slide frames 5 close to the top of the aluminum alloy mesh via the return frame 11. Frame 5 moves the connecting plate 12 downward via the mounting rod 13, causing the connecting plate 12 to bring the pressure roller 8 into contact with the top of the aluminum alloy mesh. As the mounting plate 4 moves, the pressure roller 8 moves along the top of the aluminum alloy mesh and, through the connecting plate 12, drives the mounting rod 13 to rotate, compressing the coil spring 15. The four pressure rollers 8 then simultaneously push the top of the aluminum alloy mesh, flattening it. The drive motor 19 then drives the corresponding screw 17 to rotate via the first synchronous belt. With the cooperation of multiple first conical wheels 18, the other three screws 17 rotate synchronously. The screw 17 drives the corresponding moving block 6 to move along the outer side of the optical axis, causing the moving block 6 to move the welder 7 via the L-shaped support arm 20. The four welders 7 can then... The aluminum alloy mesh is welded to the frame to ensure welding quality. The top of the mounting plate 4 has four centrally symmetrically distributed ventilation windows to facilitate the discharge of fumes generated during welding by the welder 7. Multiple equidistant anti-slip sleeves 36 are fitted on the outer side of the pressure roller 8, and the outer side of the anti-slip sleeves 36 has multiple centrally symmetrically distributed anti-slip patterns to increase the friction between the pressure roller 8 and the aluminum alloy mesh, facilitating the pressing of the top of the aluminum alloy mesh. A baffle 37 is fixedly installed on the top of the processing platform 1. When the frame is placed on the processing platform 1, it can be pressed against the outer side of the baffle 37, facilitating alignment between the frame and the mounting plate 4. Interlocking second conical wheels 38 are fixedly installed on the outer sides of adjacent mounting rods 13. When any mounting rod 13 rotates…All four pressure rollers 8 can synchronously push the surface of the aluminum alloy mesh by driving the corresponding mounting rod 13 to rotate synchronously through the second conical wheel 38. The outer side of the sliding frame 5 has a groove for limiting the sliding of the L-shaped support arm 20, and a guide rod 39 that slides through the L-shaped support arm 20 is fixedly installed on the inner side of the groove. This allows the groove of the sliding frame 5, in conjunction with the guide rod 39, to provide support for the L-shaped support arm 20, ensuring the stability of the welding by the welder 7.

[0022] Example 2: Please refer to Figures 2-8 This embodiment further illustrates Example 1. The pushing mechanism shown in the figure includes a sleeve frame 9 disposed at the bottom of the mounting plate 4. The sleeve frame 9 can push the frame body to the middle position of the processing platform 1. The side pushing mechanism also includes four pressure strips 21 arranged symmetrically inside the sleeve frame 9. A push plate 22 is fixedly installed on the side of the pressure strip 21 near the sleeve frame 9. A sliding cavity for limiting the sliding of the push plate 22 is opened on the inner side of the sleeve frame 9. A pressure groove is opened on the side of the push plate 22 away from the pressure strip 21. A pressure plate 23 is slidably installed on the inner side of the pressure groove. The bottom of the pressure plate 23 is flush with the pressure strip 21. The top of the pressure groove is a sloping structure. Two symmetrically distributed T-shaped rods 24 are fixedly installed on the side of the push plate 22 away from the pressure strip 21, and the T-shaped rods 24 slide through the sleeve frame 9. A tension spring 25 is fixedly installed between one end of the T-shaped rod 24 and the outer side of the sleeve frame 9. The pressure plate 23 is slidably installed inside the sliding cavity, and multiple equidistant support rods 26 are fixedly installed between the pressure plate 23 and the bottom of the mounting plate 4. Four centrally symmetrically distributed sleeve plates 27 are fixedly installed inside the sleeve frame 9, and the sleeve plates 27 are fitted onto the outer side of the loop frame 11. Multiple springs 28, evenly distributed, are fixedly installed between the top of plate 27 and the bottom of mounting plate 4. During the downward movement of mounting plate 4, the sleeve plate 27 moves synchronously via the return frame 11, causing the sleeve plate 27 to bring the sleeve frame 9 into contact with the top of processing platform 1. Under the resistance of processing platform 1 against the sleeve frame 9, the sleeve frame 9 stops moving, and the sleeve plate 27 compresses the springs 28. Meanwhile, mounting plate 4 pushes pressure plate 23 downward via support rod 26, causing the inclined surface of pressure plate 23 to push the inclined surface of the pressure groove of push plate 22. Push plate 22 then... It can move horizontally along the inner side of the sliding cavity, so that the push plate 22 drives the pressure strip 21 and the two T-shaped rods 24 to move synchronously. The T-shaped rods 24 compress the tension spring 25, and the pressure strip 21 contacts the outer side of the frame. The four pressure strips 21 can push the frame directly under the mounting plate 4, so that the four pressure rollers 8 are aligned with the aluminum alloy mesh, ensuring the accuracy of the pressure rollers 8 pressing the aluminum alloy mesh. The outer side of the pressure strip 21 and the bottom of the sleeve 9 are made of rubber, so that the pressure strip 21 can elastically press the outer side of the frame and provide protection for the bottom of the sleeve 9.

[0023] Example 3: Please refer to Figures 2-6This embodiment further illustrates other embodiments. The material removal mechanism shown in the figure includes a metal roller brush 10 disposed at the bottom of the sliding frame 5. The metal roller brush 10 can scrape off the oxide scale on the surface of the aluminum alloy mesh. The material removal mechanism also includes a fixing plate 29 fixedly installed on the outside of the L-shaped support arm 20. A mounting cover 30 is fixedly installed on the end of the fixing plate 29 away from the L-shaped support arm 20. The metal roller brush 10 is rotatably installed on the outside of the mounting cover 30. A first rotating rod 31 is fixedly installed on one end of the metal roller brush 10. A mounting frame 32 is fixedly installed between the outside of the mounting cover 30 and the bottom of the moving block 6. One end of the first rotating rod 31 is rotatably installed on the inside of the mounting frame 32. A second rotating rod 33 is rotatably installed on the outside of the mounting frame 32. A rack 40 is fixedly installed on the bottom of the sliding frame 5. A meshing rod is fixedly installed on the outside of the second rotating rod 33. The gear 34 is connected to the first rotating rod 31 via the second synchronous belt. A scraper 35 is fixedly installed on the outside of the mounting cover 30. When the moving block 6 moves, it can drive the mounting cover 30 to move synchronously via the mounting frame 32 and the fixing plate 29 on the outside of the L-shaped support arm 20. This causes the metal roller brush 10 inside the mounting cover 30 to move along the top of the aluminum alloy mesh. In addition, the mounting frame 32 drives the gear 34 on the second rotating rod 33 to roll along the bottom of the rack 40. This causes the rack 40 to drive the second rotating rod 33 to rotate via the gear 34. The second rotating rod 33 can then drive the first rotating rod 31 to rotate via the second synchronous belt. The first rotating rod 31 drives the metal roller brush 10 to rotate, causing the metal roller brush 10 to rotate and clean the oxide scale on the surface of the aluminum alloy mesh. The scraper 35 scrapes off the residual oxide scale, making it easier for the welder 7 to weld the aluminum alloy mesh.

[0024] Working principle: First, the operator places the aluminum alloy mesh inside the frame and pushes the frame below the mounting plate 4, so that the outer side of the frame contacts the baffle 37. Then, the operator activates the electric push rod 3, which pushes the mounting plate 4 downward, causing the mounting plate 4 to move along the four sliding frames 5 via the loop frame 11 to bring them close to the top of the aluminum alloy mesh. At the same time, the loop frame 11 moves the sleeve frame 9 downward via the four sleeve plates 27. Subsequently, the bottom of the sleeve frame 9 contacts the top of the processing platform 1. Under the resistance of the processing platform 1 on the sleeve frame 9, the sleeve frame 9 stops moving, while the mounting plate 4 continues to move downward. The mounting plate 4 compresses the spring 28 at the top of the sleeve plate 27 and pushes the pressure plate 23 downward via the support rod 26. The inclined surface of the pressure plate 23 pushes the inclined surface of the pressure groove of the push plate 22, causing the push plate 22 to move horizontally along the inner side of the sliding cavity. The push plate 22 drives the pressure strip 21 and the two T-shaped rods 24 to move synchronously. The T-shaped rods 24 compress the tension spring 25, and the outer side of the pressure strip 21 contacts the outer side of the frame. Thus, the four pressure strips 21 contact synchronously and push the frame directly below the mounting plate 4. At this time, the sliding frame 5 drives the mounting rod 13 to move synchronously, causing the mounting rod 13 to drive the connecting plate 12 to move downward. The connecting plate 12 drives the pressure roller 8 to contact the top of the aluminum alloy mesh, causing the anti-slip sleeve 36 on the outer side of the pressure roller 8 to move along the top of the aluminum alloy mesh. The pressure roller 8 drives the connecting plate 12 to swing, and the connecting plate 12 drives the mounting rod 13 to rotate, causing the mounting rod 1 to move downward. 3. The coil spring 15 is compressed, and the four pressure rollers 8 simultaneously push the top of the aluminum alloy mesh, laying the aluminum alloy mesh flat on the inner side of the frame. At the same time, the bottom of the metal roller brush 10 contacts the top of the aluminum alloy mesh. Then, the operator starts the drive motor 19, which drives the corresponding screw 17 to rotate via the first synchronous belt. The screw 17, with the cooperation of multiple first conical wheels 18, drives the other three screws 17 to rotate synchronously. The screw 17 drives the corresponding moving block 6 to move along the outer side of the optical axis. The moving block 6 drives the L-shaped support arm 20 to move along the slide groove of the sliding frame 5, so that the L-shaped support arm 20 drives the welder 7 and the fixing plate 29 to move synchronously, so that the mounting frame 32 at the bottom of the moving block 6 cooperates with the fixing plate 29. The moving mounting cover 30 moves synchronously, causing the metal roller brush 10 inside the mounting cover 30 to move along the top of the aluminum alloy mesh. At the same time, the mounting frame 32 drives the gear 34 on the second rotating rod 33 to roll along the bottom of the rack 40, causing the rack 40 to drive the second rotating rod 33 to rotate through the gear 34. The second rotating rod 33 then drives the first rotating rod 31 to rotate through the second synchronous belt. The first rotating rod 31 drives the metal roller brush 10 to rotate, causing the metal roller brush 10 to rotate and clean the oxide scale on the surface of the aluminum alloy mesh. The scraper 35 then scrapes off any remaining oxide scale. Finally, the four welders 7 weld the aluminum alloy mesh onto the frame, ensuring the welding quality of the aluminum alloy mesh and thus achieving a high-efficiency welding effect, improving the welding efficiency between the aluminum alloy mesh and the frame.
