[0003] Reference patent (Publication No.: CN222806348U; Publication Date: April 29, 2025) discloses a welding device, which relates to the technical field of electronic component welding. It includes a support table, a rotating plate, a slider, and a mounting shell. One side of the mounting block is provided with a first gear, the output end of the second motor is provided with a second gear. Two groups of the inner parts of the limiting shell are fitted and movably provided with sponge layers, and two groups of the inner parts of the limiting shell are fitted and movably provided with activated carbon plates. By setting components such as the second motor, sponge layers, and activated carbon plates, when the second motor operates, the mounting block drives the electric welding assembly to swing back and forth for angle adjustment during use, effectively improving the convenience of the welding device when welding electronic components. The sponge layer can filter impurities in gases or fumes, and then, the activated carbon plate can filter odors in the gases, effectively reducing the pollution of harmful substances in the gases to the surrounding environment and the harm to the health of the staff.

[0004] Based on the above patent, the clamping mechanisms of some automatic welding machines are difficult to achieve stable clamping of workpieces with different shapes. For special-shaped parts or curved surface welding scenarios, traditional fixed-angle clamping plates cannot accurately fit the workpieces, easily resulting in problems such as insecure clamping or workpiece deformation. In addition, traditional welding machines mostly adopt a single-piece welding mode. After welding is completed, manual loading, unloading, and positioning of workpieces are required, resulting in long idle times of the equipment and making it difficult to achieve continuous and assembly-line operations. Therefore, the present invention provides a multifunctional automatic welding machine and its usage method.

[0035] Please refer to Figures 1-8 , the present invention provides a technical solution

[0036] A multifunctional automatic welding machine includes a mounting base 1, and a mounting mechanism for the processing of the automatic welding machine is arranged on the mounting base 1. The mounting mechanism includes:

[0037] An adjusting component, including an L-shaped rod 4 connected through a gear component is arranged on the upper end surface of the mounting base 1. A support block 401 is fixed at the upper end of the L-shaped rod 4, a mounting platform 7 is fixed at the top of the support block 401, and the L-shaped rod 4 is arranged in four groups;

[0039] In a preferred embodiment, a mounting shaft seat 3 rotates on the upper end surface of the gear assembly. A tooth block 301 is fixed on the outer wall of the mounting shaft seat 3. The L-shaped rod 4 is fixedly connected to the upper end surface of the mounting shaft seat 3. One side of the upper end surface of the mounting base 1 is fixedly provided with a mounting bracket 302. A motor 303 is fixed on the inner wall of the mounting bracket 302. A transmission gear 304 is fixed on the output end of the motor 303. The transmission gear 304 is meshed with the tooth block 301. A support rod 2 is fixed at the edge of the mounting base 1. The upper end of the support rod 2 is fixedly provided with a support ring 201. The mounting platform 7 is in sliding connection with the upper end surface of the support ring 201 in a fitting manner. The provided transmission gear 304 is driven by the motor 303. Then, the mounting shaft seat 3 rotates on the mounting base 1 through the meshing action of the tooth block 301 and the transmission gear 304, and then drives the L-shaped rod 4 and the support block 401 fixed on the upper end surface of the mounting shaft seat 3 to rotate along the inner wall of the support ring 201 in a fitting manner, so that the mounting platform 7 at the top of the support block 401 rotates along the upper surface of the support ring 201. The mounting platform 7 is used for fixing the welded object. Then, four groups of mounting platforms 7 are provided. After welding the object on one group of mounting platforms 7 is completed, the mounting platform 7 is rotated in time, and other mounting platforms 7 are supplemented, and processing is carried out in time, without waiting for the welding of a single object to be completed and then clamping and positioning the next object, realizing the continuous progress of the welding work, greatly improving the welding efficiency, realizing the flow operation of the welding work, and making the welding process more orderly and efficient.

[0040] In a preferred embodiment, an installation rod 5 is fixed at the center of the upper end surface of the installation base 1. The upper end of the installation rod 5 is fixed with a U-shaped bracket 501. The upper end of the U-shaped bracket 501 is fixed with a support column 502. The top end of the support column 502 is fixed with a slide rail bracket 503. A first electric push rod 504 is fixed inside the slide rail bracket 503. The telescopic end of the first electric push rod 504 is fixed with a slider 505. The slider 505 is slidably connected to the slide rail bracket 503. A second electric push rod 506 is fixed in the vertical direction of the slider 505. The telescopic end of the second electric push rod 506 is fixed with a welding gun 507. A collection housing 6 is fixed inside the U-shaped bracket 501. A dust suction housing 601 connected by a conduit is fixed to the side wall of the collection housing 6. A wire mesh frame 602 is fixed at the suction port of the dust suction housing 601. The installation base 1 provides a stable support foundation for the entire device. The installation rod 5 installed at the center of the upper end surface of the installation base 1 fixedly connects components such as the U-shaped bracket 501, the support column 502, and the slide rail bracket 503 upward in sequence to form a support structure for the welding gun 507. For the position of the object to be welded on the installation platform 7, start the first electric push rod 504. The first electric push rod 504 expands and contracts, driving the slider 505 fixed to its telescopic end to slide inside the slide rail bracket 503, thereby adjusting the position of the welding gun 507 in the horizontal direction to make it in a suitable horizontal position. After the position adjustment is in place, start the second electric push rod 506. The second electric push rod 506 expands and contracts, driving the welding gun 507 to move in the vertical direction to accurately align the welding gun 507 with the part to be welded, preparing for the welding work. During the welding process, the welding fumes and spatter generated will spread in all directions. At this time, the collection housing 6 plays a role. Using the suction force generated by the connection between the dust suction housing 601 and the collection housing 6 through the conduit, the welding fumes and spatter generated are sucked into the collection housing 6. The wire mesh frame 602 at the suction port of the dust suction housing 601 can intercept larger spatter to prevent it from entering the dust suction pipeline and causing blockage, while ensuring that air and fine dust can pass through smoothly and be sucked in. When the welding of the objects on a group of installation platforms 7 is completed, the transmission gear 304 rotates driven by the motor 303. Through the meshing of the tooth block 301 and the transmission gear 304, the installation shaft seat 3 rotates on the installation base 1, driving the L-shaped rod 4, the support block 401, and the installation platform 7 to rotate along the support ring 201, moving the installation platform 7 of the next group of objects to be welded under the welding gun 507, and repeating the above steps to continue welding. The dust collection system composed of the collection housing 6, the dust suction housing 601, and the wire mesh frame 602 can timely collect the fumes and spatter generated during the welding process, reduce the concentration of harmful fumes in the workshop, improve the working environment, protect the physical health of the operators, and reduce the risk of occupational diseases. When the welding of a group of objects is completed, the next group of objects to be welded can be quickly moved to the welding position, reducing the idle time of the equipment, greatly improving the welding efficiency, and increasing the output per unit time. The dust suction pump for generating negative pressure is provided at the upper end of the collection housing 6, which belongs to the prior art.No further elaboration will be made.

[0041] In a preferred embodiment, the opening and closing assembly includes a chute 701 formed on the upper end surface of the installation platform 7. A bidirectional screw 702 is rotatably connected horizontally inside the chute 701. The movable plate 703 is slidably connected to the inner wall of the chute 701. The bidirectional screw 702 is threadedly connected to the movable plate 703. A pair of positioning grooves 704 are formed on the upper end surface of the installation platform 7. The movable plate 703 is slidably connected to the installation platform 7 through the positioning grooves 704. By rotating the bidirectional screw 702, the two groups of movable plates 703 are driven to open and close along the positioning grooves 704 on the installation platform 7 through the bidirectional screw 702, so as to open and close the clamping plates 801 inside the movable plates 703 and clamp the objects to be welded. Since the movable plate 703 can be opened and closed by rotating the bidirectional screw 702, the opening and closing assembly can adapt to welding objects of different sizes, and the operation method is simple and intuitive.

[0042] In a preferred embodiment, the pushing component includes a moving groove 802 formed in the inner wall of the moving plate 703. A lead screw 803 is rotatably connected inside the moving groove 802. A moving block 804 is slidably connected to the inner wall of the moving groove 802. The moving block 804 is threadedly connected to the lead screw 803. A moving rod 805 is rotatably connected to the side wall of the moving block 804 through a rotating shaft. The end of the moving rod 805 is rotatably connected to the clamping plate 801 through a rotating shaft. The locking component includes a locking block 902 fixed to the outer wall of the connecting shaft 901. Locking holes 903 are evenly formed in the outer wall of the locking block 902. A third electric push rod 904 is fixed inside the connecting block 8. The telescopic end of the third electric push rod 904 is fixed with a locking plate 905. A locking rod 906 that is engaged with the locking holes 903 is fixed to the inner wall of the locking plate 905. The provided clamping plate 801 is used to clamp and fix an object. Then, by rotating the lead screw 803, the moving block 804 slides along the moving groove 802 on the inner wall of the moving plate 703 through the lead screw 803. Then, the clamping plate 801 rotates with the moving plate 703 through the rotating shafts at both ends of the moving rod 805. When the angle of the moving rod 805 changes, the clamping plate 801 is pushed, and the clamping plate 801 adjusts its angle on the connecting block 8 through the connecting shaft 901. The angle is adjusted according to the welded object, so that the clamping plate 801 can flexibly adjust the clamping angle according to different shapes and different welding position requirements. Whether it is flat welding, inclined welding or complex curved surface welding, it can closely fit the surface of the object for clamping, greatly improving the adaptability of the welding machine to diverse welding tasks, making the clamping plate 801 match the special contour of the workpiece, filling the gap in the traditional clamping method when dealing with special-shaped parts, ensuring that workpieces of various complex shapes can be stably clamped, providing guarantee for high-quality welding. After the clamping plate 801 rotates and adjusts on the connecting block 8 through the connecting shaft 901, the third electric push rod 904 arranged inside the connecting block 8 drives the locking plate 905 and the locking rod 906 on the inner wall to engage with the locking block 902 on the outer wall of the connecting shaft 901 and the evenly distributed locking holes 903 inside, so as to fix the rotationally adjusted connecting shaft 901, ensure the stability of the clamping plate 801, provide a strong and stable locking force, firmly fix the connecting shaft 901, prevent the clamping plate 801 from deviating in angle due to factors such as vibration and arc force during the welding process, ensure that the workpiece always maintains a fixed posture during the entire welding process, and effectively improve the welding quality and consistency.

[0043] Meanwhile, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0044] A usage method of a multifunctional automatic welding machine includes the following steps:

[0045] Step 1: Place the hardware workpiece to be welded on the installation platform 7. Rotate the bidirectional screw 702. Drive the movable plate 703 and the clamping plate 801 to clamp the workpiece through the opening and closing assembly. Start the motor 303. Test that the driving gear 304 drives the installation shaft seat 3 to rotate. Check whether the sliding of the installation platform 7 along the support ring 201 is smooth to ensure the normal operation of the equipment. Specifically, by rotating the bidirectional screw 702, drive the two groups of movable plates 703 to open and close along the positioning groove 704 on the installation platform 7 through the bidirectional screw 702, so as to open and close the clamping plate 801 inside the movable plate 703 and clamp the object to be welded. Then, by rotating the lead screw 803, the movable block 804 slides along the movable groove 802 on the inner wall of the movable plate 703 through the lead screw 803. Then, the clamping plate 801 rotates with the movable plate 703 through the rotating shafts at both ends of the movable rod 805. When the angle of the movable rod 805 changes, the clamping plate 801 is pushed, and the clamping plate 801 adjusts the angle on the connecting block 8 through the connecting shaft 901 and adjusts the angle according to the object to be welded.

[0046] Step 2: According to the welding position of the workpiece, start the first electric push rod 504 and the second electric push rod 506, adjust the horizontal and vertical positions of the welding gun 507, rotate the lead screw 803, adjust the angle of the clamping plate 801 through the top pushing assembly to adapt to the workpiece, and then drive the locking assembly to fix the clamping plate 801 by the third electric push rod 904. Specifically, start the first electric push rod 504. The first electric push rod 504 expands and contracts, driving the slider 505 fixed to its telescopic end to slide inside the slide rail bracket 503, so as to adjust the position of the welding gun 507 in the horizontal direction and make it in a suitable horizontal position. After the position adjustment is in place, start the second electric push rod 506. The second electric push rod 506 expands and contracts, driving the welding gun 507 to move in the vertical direction, so that the welding gun 507 accurately aligns with the part to be welded and prepares for the welding work. During the welding process, the welding fumes and spatter will spread in all directions. At this time, the collection housing 6 plays a role. Using the suction force generated by connecting the dust suction housing 601 to the collection housing 6 through a conduit, the welding fumes and spatter generated during welding are sucked into the collection housing 6. The grid 602 at the suction port of the dust suction housing 601 can intercept larger spatter and prevent it from entering the dust suction pipeline and causing blockage.

[0047] Step 3. Finally, after a group of workpieces are welded, the motor 303 drives the transmission gear 304, which drives the mounting shaft seat 3 through the tooth block 301 to rotate the mounting platform 7 of the next group of workpieces to be welded under the welding gun 507. Specifically, the set transmission gear 304 is driven by the motor 303, and then the mounting shaft seat 3 rotates on the mounting base 1 through the meshing of the tooth block 301 and the transmission gear 304. Then, it drives the L-shaped rod 4 and the support block 401 fixed on the upper end surface of the mounting shaft seat 3 to fit and rotate along the inner wall of the support ring 201, so that the mounting platform 7 at the top of the support block 401 rotates along the upper surface of the support ring 201. The mounting platform 7 is used to fix the objects to be welded. Then, the mounting platform 7 is set in four groups. After the objects on one of the mounting platforms 7 are welded, the mounting platform 7 is rotated in time to replace the other mounting platforms 7, and processing is carried out in time without waiting for a single object to be welded and then clamping and positioning the next object, realizing the continuous progress of the welding work, greatly improving the welding efficiency, and realizing the flow operation of the welding work.

[0048] During operation, first, by rotating the bidirectional screw rod 702, two sets of movable plates 703 are driven to open and close along the positioning groove 704 on the mounting platform 7 through the bidirectional screw rod 702, so as to open and close the clamping plates 801 inside the movable plates 703 to clamp the objects to be welded. Then, by rotating the screw rod 803, the movable block 804 is realized to slide along the movable groove 802 on the inner wall of the movable plate 703 through the screw rod 803. Then, the clamping plate 801 rotates with the movable plate 703 through the rotating shafts at both ends of the movable rod 805. When the angle of the movable rod 805 changes, the clamping plate 801 is pushed, and the clamping plate 801 is adjusted in angle on the connecting block 8 through the connecting shaft 901, and the angle is adjusted according to the objects to be welded;

[0049] Then, to adjust the position of the object to be welded on the mounting platform 7, the first electric push rod 504 is started. The first electric push rod 504 expands and contracts, driving the slider 505 fixed to its telescopic end to slide inside the slide rail bracket 503, so as to adjust the position of the welding gun 507 in the horizontal direction to make it in a suitable horizontal position. After the position adjustment is in place, the second electric push rod 506 is started. The second electric push rod 506 expands and contracts, driving the welding gun 507 to move in the vertical direction to accurately align the welding gun 507 with the part to be welded, and prepare for the welding work. During the welding process, the welding fumes and spatter will spread in all directions. At this time, the collection housing 6 plays a role. Using the suction force generated by connecting the suction housing 601 to the collection housing 6 through a conduit, the welding fumes and spatter generated during welding are sucked into the collection housing 6. The wire mesh frame 602 at the suction port of the suction housing 601 can intercept larger spatter to prevent it from entering the suction pipeline and causing blockage, while ensuring that air and fine fumes pass through smoothly and are sucked in;

[0050] Finally, the provided transmission gear 304 is driven by the motor 303, and then the mounting shaft seat 3 rotates on the mounting base 1 through the meshing of the tooth block 301 and the transmission gear 304. Then, the L-shaped rod 4 and the support block 401 fixed to the upper end surface of the mounting shaft seat 3 rotate along the inner wall of the support ring 201, causing the mounting platform 7 at the top of the support block 401 to rotate along the upper surface of the support ring 201. The mounting platform 7 is used to fix the object to be welded. Then, four groups of mounting platforms 7 are provided. After welding the object on one group of mounting platforms 7 is completed, the mounting platform 7 is rotated in time to replace it with other mounting platforms 7, and processing is carried out in time without waiting for the welding of a single object to be completed before clamping and positioning the next object.
