Description

Technical Field

[0001] This invention relates to the field of composite screw welding technology, specifically to an automated integrated equipment for composite screw welding. Background Technology

[0002] Automated composite screws require welding during processing and assembly, and welding is one of the necessary steps in the production and assembly of composite screws.

[0003] Existing technology 1 (Chinese patent with announcement number CN119216730B and announcement date of 2025-06-06) discloses an automatic arc welding machine for processing countersunk small self-tapping cement screws, including an operating platform, a robotic arm for picking up screws, and a welding gun for welding screws and plates. A housing is installed on the upper side of the operating platform, and a support frame for conveying screws is installed inside the housing. First grooves for placing screws are symmetrically opened on both sides of the support frame. A movable frame for advancing screws is movably installed between the operating platforms. A drive motor for driving the movable frame is installed on the side wall of the support frame. A support platform is installed on the upper side of the operating platform, and a detection head for checking the screw orientation is installed on the side of the support platform. A conversion seat for adjusting the screw orientation is installed on the upper side of the operating platform. After the robotic arm picks up the screw and connects it with the metal plate, the welding gun is used to weld it, realizing automated welding, reducing labor costs, and improving production efficiency and welding quality.

[0004] There is also existing technology 2 (Chinese patent with announcement number CN215879051U and announcement date of 2022-02-22) which describes a processing device for special welding screws for automobiles, including an upper mold base; a lower mold base is provided at the top of the upper mold base, and the lower mold base and the upper mold base are connected by guide pillars and guide sleeves. A first station, a second station, a third station, a fourth station, a fifth station, and a sixth station are arranged sequentially between the upper mold base and the lower mold base. This solves the problem of inconvenience in mass production of special screws. It can form the screws in one step on a multi-station device without the need for secondary processing. Only one process is required, which improves production efficiency, reduces the generation of very little scrap material, saves resources, and reduces costs. After the equipment is debugged, the processing process is efficient and continuous, reduces the labor intensity of human workers, improves the convenience of operation for operators, and improves the work efficiency of operators.

[0005] Existing technologies mostly only allow for welding and fixing composite screws at a single location. After welding one side, manual intervention is required to adjust the screw position before proceeding with subsequent welding operations. This cumbersome process significantly reduces the efficiency of composite screw welding. Furthermore, the fumes generated during welding contain impurities that diffuse directly into the working environment, posing a health hazard to operators. Therefore, the overall practicality is poor. Consequently, we propose an automated integrated composite screw welding equipment to address the aforementioned problems. Summary of the Invention

[0006] The purpose of this invention is to provide an automated composite screw welding and processing integrated equipment to solve the problems currently found in the market as described in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an automated composite screw welding processing integrated equipment, including a processing table, a welding frame fixedly connected to the upper surface of the processing table, and the welding frame is provided with an adjustment frame, and a welding head is provided on the adjustment frame. An adjustment platform is also provided on the processing table, and a placement frame is provided on the upper surface of the adjustment platform, and an adjustment mechanism is provided on the upper surface of the placement frame. The adjustment mechanism realizes multi-angle rotation of the screw to be processed through the mutual cooperation of the gears and gear rings contained therein, thereby improving welding efficiency.

[0008] Preferably, the adjustment frame is horizontally arranged on the welding frame, the welding head is slidably connected to the adjustment frame, and the welding head is vertically moved by an electric push rod provided on its rear side to complete the flexible adjustment of the welding position.

[0009] Preferably, the adjustment platform has sliding grooves on its left and right sides, and the placement racks are slidably connected to each other. The lower side of the placement rack is connected to the electric guide rail provided on the upper surface of the adjustment platform, so that the placement rack can move back and forth through the electric guide rail.

[0010] Preferably, the adjustment mechanism includes a motor, which is fixedly connected to the lower surface of the placement rack, and the output end of the motor is fixedly connected to a rotating disk, which is disposed on the upper surface of the placement rack.

[0011] Preferably, a gear is rotatably connected to the upper surface of the rotating disk, and a placement box is fixedly connected to the upper surface of the gear. A disk frame is fixedly connected to the upper surface of the placement box, and a groove is provided in the middle of the disk frame for placing the screw to be processed.

[0012] Preferably, the side of the tray frame is slidably connected with an abutment rod, the inner end of the abutment rod is arranged in an arc shape, and the outer end of the abutment rod is fixedly connected to the outer side of the tray frame with a spring. At the same time, three sets of abutment rods are arranged in a circular array about the center point of the tray frame.

[0013] Preferably, a magnetic suction block is fixedly connected to the central groove of the tray frame. The magnetic suction block achieves initial adsorption and fixation of the screw. Combined with the elastic clamping of the abutment rod, it prevents the screw from shifting or shaking during processing and improves the stability of welding.

[0014] Preferably, a toothed ring is fixedly connected to the upper surface of the placement rack, and the toothed ring is adapted to a gear, so that the placement box can be rotated by the meshing action of the toothed ring and the gear.

[0015] Preferably, the inside of the placement box is fixedly connected to an adsorption plate for adsorbing impurities in the welding fumes, and a suction box is fixedly connected to the center of the rotating disk, and a deformable connecting pipe is connected through the bottom of the suction box placement box.

[0016] Compared with existing technologies, the advantages of this invention are as follows: This automated composite screw welding processing integrated equipment drives the screw to rotate through an adjustment mechanism, enabling multi-angle welding processing without manual adjustment of the welding position. Combined with the forward and backward movement of the placement frame and the flexible adjustment of the welding head, it can adapt to the welding processing of screws of different specifications, expanding the equipment's adaptability. Simultaneously, the contact rod, in conjunction with the magnetic suction block, provides double fixation for the screw, preventing it from shifting during the welding process and effectively ensuring welding accuracy. Furthermore, during the welding process, the equipment can extract the welding fumes through the suction box, and with the adsorption plate adsorbing impurities in the fumes, it reduces the impact of welding fumes on the processing environment and operators, improving processing safety and environmental friendliness. This automated composite screw welding and processing integrated equipment uses magnetic suction blocks and elastic abutment rods to provide double stable fixation for the screws to be processed, preventing the screws from shaking or shifting during the welding process and improving the accuracy of the welding process. Compared with the traditional single fixation method, it has stronger adaptability and can stably clamp and fix screws of different sizes to be processed.

[0017] During the rotation of the rotating disk and the gear, the gear meshes with the gear ring fixed on the placement frame, thereby causing the gear and the placement box to rotate as a whole. In conjunction with the rotation of the rotating disk, the welding angle of the screw can be quickly adjusted without the need for manual disassembly and reassembly to adjust the screw position, effectively improving the welding efficiency.

[0018] The equipment can draw welding fumes into the placement box through the suction box and connecting pipe, filter them through the adsorption plate, and then discharge them. This can effectively reduce the pollution of the working environment by welding fumes and improve the working environment of the workers. The overall structure is compact and reasonable, integrating fixing, angle adjustment and fume treatment functions, and is suitable for the needs of automated screw welding processing.

[0019] Equipped with magnetic suction blocks, it can initially attract and position screws, making it convenient for workers to quickly load and place them. At the same time, the contact rod, under the elastic force of the spring, can automatically conform to the outer wall of screws of different diameters to complete elastic clamping, eliminating the need for additional clamping size adjustment and simplifying the operation process.

[0022] 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.

[0023] Example 1: As Figure 1 , Figure 2 and Figure 3The present invention provides the following technical solution: an automated composite screw welding processing integrated equipment, wherein a welding frame 3 is fixedly connected to the upper surface of the processing table 1, and the welding frame 3 is provided with an adjustment frame 4, and a welding head 7 is provided on the adjustment frame 4. The adjustment frame 4 is horizontally arranged on the welding frame 3, and the welding head 7 is slidably connected to the adjustment frame 4. The welding head 7 is vertically moved by an electric push rod provided on its rear side to complete the flexible adjustment of the welding position. Slide grooves 9 are opened on the left and right sides of the adjustment platform 2, and the placement frame 6 is slidably connected to the placement frame 6. The lower side of the placement frame 6 is connected to an electric guide rail provided on the upper surface of the adjustment platform 2, and the placement frame 6 is moved back and forth by the electric guide rail.

[0024] Equipped with a welding frame 3 and an adjustment frame 4, the welding head 7 can be adjusted laterally. With the help of an electric push rod, the welding head 7 can be adjusted vertically. Furthermore, with the forward and backward movement of the placement frame 6, the position of the screw to be processed can be adjusted, thereby flexibly completing welding processing work in different positions and improving the adaptability of the equipment.

[0025] Equipped with an adjustment platform 2, the placement rack 6 can slide along the slide groove 9 on the adjustment platform 2 under the drive of the electric guide rail. In conjunction with the revolution of the rotating disk 5 and the rotation of the placement box 10, the screw position and welding angle can be quickly adjusted according to welding requirements, eliminating the need for repeated manual disassembly and adjustment, saving operation time and improving welding processing efficiency.

[0026] Example 2: Stability and efficiency of screw welding. First, the screw to be processed is placed in the groove in the middle of the tray 13. The screw is initially attracted and positioned by the magnetic suction block 14, completing the loading process. During placement, the screw will press against the contact rod 15. After being compressed, the contact rod 15 slides outwards from the tray 13 and compresses the spring 16. Subsequently, the spring 16 pushes the contact rod 15 to elastically return to its original position, causing the contact rod 15 to adhere to the outer wall of the screw, thus elastically clamping and fixing the screw. This achieves stable fixing of screws of different sizes, preventing screw displacement and shaking during welding. Figure 6 - Figure 9The present invention provides the following technical solution: an automated composite screw welding processing integrated equipment, wherein the processing table 1 is further provided with an adjustment platform 2, and the upper surface of the adjustment platform 2 is provided with a placement rack 6, and the upper surface of the placement rack 6 is provided with an adjustment mechanism. The adjustment mechanism realizes multi-angle rotation of the screw to be processed through the mutual cooperation of the gear 17 and the gear ring 18 contained therein, thereby improving welding efficiency. The adjustment mechanism includes a motor 8, which is fixedly connected to the lower surface of the placement rack 6, and the output end of the motor 8 is fixedly connected to a rotating disk 5. The rotating disk 5 is disposed on the upper surface of the placement rack 6, and the upper surface of the rotating disk 5 is rotatably connected to a gear 17. The upper surface of the gear 17 is fixedly connected to a placement box 10, and the upper surface of the placement box 10 is fixedly connected to a plate frame 13. The plate frame 13 has a groove in the middle, through which the screw to be processed is placed.

[0027] To facilitate understanding of this automated composite screw welding and processing integrated equipment, the following is a detailed description of its working process: First, the composite screw to be processed is placed in the groove in the middle of the disc frame 13. The magnetic suction block 14 in the groove of the disc frame 13 will first perform initial adsorption and positioning of the screw. At this time, the abutment rod 15, which is slidably connected to the side of the disc frame 13, will automatically adhere to the outer wall of the screw under the elastic force of the spring 16, thus completing the elastic clamping and fixing of the screw, adapting to the stable fixing requirements of screws of different sizes.

[0028] After the screw to be processed is placed into the groove in the middle of the tray 13, the magnetic suction block 14 will initially attract and position the screw, completing the initial fixation. At this time, the three sets of abutment rods 15 will automatically fit against the outer wall of the screw under the elastic force of the spring 16, completing the elastic clamping of the screw, which can adapt to screws of different diameters and achieve stable double fixation, avoiding the screw shaking and displacement during processing. The operation of the motor 8 synchronously drives the rotating disk 5 to rotate, and the rotating disk 5 drives the gear 17 to revolve around the central axis of the rotating disk 5, which can quickly adjust the welding angle of the screw at multiple angles. There is no need to manually stop the machine to adjust the screw position, and multi-position welding operations can be completed, effectively improving the efficiency of automated processing.

[0029] Example 3: To further ensure a healthy working environment during welding, the suction box 11 maintains a continuous suction state during welding operations. Welding fumes enter the placement box 10 through pre-reserved ventilation gaps, and then enter the suction box 11 through the connecting pipe 12. Welding fumes and other impurities in the fumes are adsorbed and intercepted by the adsorption plate 19, and the filtered clean gas is then discharged. This effectively reduces the diffusion of welding fumes in the working environment and improves the air quality in the work area. Figure 4 - Figure 9The present invention provides the following technical solution: an automated composite screw welding processing integrated equipment, wherein a contact rod 15 is slidably connected to the side of the disc frame 13, and the inner end of the contact rod 15 is arranged in an arc shape, and a spring 16 is fixedly connected between the outer end of the contact rod 15 and the outer side of the disc frame 13; three sets of contact rods 15 are arranged in a circular array about the center point of the disc frame 13; a magnetic suction block 14 is fixedly connected to the central groove of the disc frame 13, and the magnetic suction block 14 achieves the initial adsorption and fixation of the screw, in conjunction with... The elastic clamping of the abutment rod 15 prevents the screw from shifting or shaking during processing, thus improving the stability of welding. A toothed ring 18 is fixedly connected to the upper surface of the placement frame 6, and the toothed ring 18 is matched with the gear 17. The meshing action of the toothed ring 18 and the gear 17 drives the placement box 10 to rotate. An adsorption plate 19 for adsorbing impurities in welding fumes is fixedly connected inside the placement box 10. An air suction box 11 is fixedly connected to the middle of the rotating disk 5, and a deformable connecting pipe 12 is connected through the air suction box 11 to the bottom of the placement box 10.

[0030] After starting the motor 8, the motor 8 will drive the rotating disk 5 to rotate, thereby causing the gear 17 and the placement box 10 to revolve around the center point of the rotating disk 5. During the revolution, the gear 17 will mesh with the gear ring 18 fixed on the placement frame 6, so that the gear 17 drives the placement box 10 and the screws that have been fixed on it to rotate synchronously. With the revolution of the rotating disk 5, the welding angle of the screws can be quickly adjusted without the need for manual disassembly and reassembly to adjust the screw position, which meets the welding processing needs of multiple positions and angles and effectively improves welding efficiency. During the welding process, the suction box 11 is activated and will draw the welding fumes generated during welding into the placement box 10 through the connecting pipe 12. When the fumes pass through the adsorption plate 19 inside the placement box 10, the impurities in the fumes will be adsorbed and filtered by the adsorption plate 19, and then the clean gas will be discharged from the equipment, thereby reducing the pollution of the working environment by welding fumes and improving the on-site working environment.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
