Description

Technical Field

[0001] The present invention relates to the field of welding technology, and in particular to a high-safety welding device and a welding process for processing intelligent doors and windows. Background Art

[0002] Before welding doors and windows, clean the profiles first, then fix the profiles of doors and windows on the positioning fixture, and weld the profile gaps while ensuring the safety of the welding environment. After the front side of the profile is welded, turn the profile over and weld the back side of the profile. In addition to the gaps on the front and back sides, the gaps on the inside and outside of each corner of the profile also need to be welded to prevent rainwater from entering the inside of the doors and windows during use. After welding, the doors and windows also need to be polished smooth using tools such as angle grinders. After polishing, the doors and windows can be colored.

[0003] After searching, the Chinese patent with the authorization announcement number CN221716100U discloses a welding device for alloy door and window processing, which relates to the field of welding technology. The device comprises a processing frame, one side of which is provided with an adjustment slot, and the processing frame is rotatably connected with a rotating column on the side close to the adjustment slot, and four frames of the aluminum alloy door and window are clamped and fixed by four pressing plates, and then the corresponding two clamping plates are driven to approach each other by the first bidirectional screw and the second bidirectional screw, so as to facilitate the alignment and welding of the four frames of the aluminum alloy door and window, and the clamping block is connected with the two clamping slots so that the clamping block can fix the rotated cross plate, and then after the welding of one side of the aluminum alloy door and window on the cross plate is completed, the cross plate can be rotated to weld the other side of the aluminum alloy door and window, thereby avoiding the situation that the aluminum alloy door and window welded on one side is not firm, which leads to the easy occurrence of welding point breakage or frame offset when flipping, thereby improving the welding effect of the aluminum alloy door and window.

[0004] In the above patent, although the profiles of doors and windows can be fixed, when the door and window profiles are placed, it cannot be guaranteed that the middle of the profile on each side is in the middle of the clamping plate. If the middle of the profile is not in the middle of the clamping plate, the corner edges between adjacent profiles cannot be aligned, and welding cannot be performed. Therefore, multiple adjustments are required to flatten the profile into a complete door and window shape. This process takes a long time, and there is a need for further optimization in terms of the convenience of positioning. Therefore, the present application provides a high-safety welding device and welding process for intelligent door and window processing to meet the needs. Summary of the invention

After the door and window profiles are placed, they are placed on the support blocks, and the servo motor drives the drive rod to press on the top of the door and window profiles through the rotating shaft. After the top and inner gap of the door and window profiles are welded by the welding manipulator, the drive rod drives the fixed surface of the outer shell to fit on the side of the door and window profiles and drives the support block to move back to the inside of the outer shell. After the outer shell gap of the door and window profiles is welded by the welding manipulator, the door and window profiles are flipped 180 degrees by the flipping assembly.

[0007] Preferably, a limiting ring is fixedly sleeved on the surface of the rotating shaft, and an end of the limiting ring is slidably connected to the inner wall of the outer shell.

[0008] Preferably, a pad is fixed on the fixed surface of the shell, and the surface of the pad is provided with anti-slip stripes.

As the drive rod rotates, it does not Just push the outer shells close together, and they can also fit onto the top of the door and window profiles, flattening them with uniform and stable pressure, effectively eliminating deviations caused by improper placement and significantly improving welding accuracy. At the same time, the drive rod can also cause the fixing surface of the outer shell to fit closely onto the side of the door and window profiles, thereby fixing the door and window profiles.

At this time, gently flip the door and window with the help of the flip assembly. After the back of the door and window profiles are welded, they can be easily taken out upwards. The entire operation process is simple and smooth, which improves the convenience of use and work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] like Figure 1-Figure 8 As shown, the embodiment of the present invention provides a high-safety welding device and welding process for intelligent door and window processing, including a support base 1 and a welding manipulator 2 installed on the support base 1, and also includes: The flip assembly 3 includes a servo motor 4 fixed on the support seat 1, and a support frame 5 is fixed to the output end of the servo motor 4. The other end of the support frame 5 is rotatably connected to the support seat 1 through the shaft seat, and the support frame 5 is rotatably connected to the top of the support seat 1. After the door and window profile 26 is welded on one side, the support frame 5 is driven by the servo motor 4 to rotate, thereby driving the door and window profile 26 to flip 180 degrees, which is convenient for welding on the other side, greatly improving the processing efficiency, reducing the tediousness and inaccuracy of manual flipping, ensuring the continuity and efficiency of the welding process, and being able to meet the production needs of large-scale intelligent doors and windows; The positioning assembly 6 includes a plurality of servo motors 27 fixed at the bottom of the support frame 5. The positioning assembly 6 is used to position the four corners of the door and window profile 26. The output end of the servo motor 27 movably penetrates the support frame 5 and is fixed with a rotating shaft 9. The surface of the rotating shaft 9 is movably sleeved with a shell 8. A vertical surface 11 and a fixed surface 12 are provided on the side of the shell 8 close to the door and window profile 26. An inclined surface 13 is provided on the side of two adjacent shells 8 close to each other. A through groove 14 is provided on the side of the shell 8 close to the door and window profile 26. A driving rod 22 is slidably connected in the through groove 14. The driving rod 22 is located in the shell 8. The driving rod 22 is driven by the driving rod 22. The end of the moving rod 22 is fixed to the circumferential surface of the rotating shaft 9, and an elastic rope 25 is fixed between the side of the driving rod 22 away from the door and window profile 26 and the inner wall of the shell 8. The elastic rope 25 is used for the driving rod 22 to pull the shell 8, so that the inclined surface 13 of the shell 8 can be quickly fitted together. The vertical surface 11 of the shell 8 is movably penetrated by a support block 15, and the support block 15 is located below the door and window profile 26. A vertical plate 16 is fixed on the top of the support block 15. A spring 18 is fixed between the side of the vertical plate 16 away from the door and window profile 26 and the inner wall of the shell 8, and the driving rod 22 is fitted on the side of the vertical plate 16 close to the door and window profile 26; Before the door and window profile 26 is placed, the inclined surfaces 13 of adjacent shells 8 are close to each other and fit together. After the door and window profile 26 is placed, the door and window profile 26 is placed on the support block 15, and the servo motor 14 drives the driving rod 22 to press on the top of the door and window profile 26 through the rotating shaft 9. After the top and the inner gap of the door and window profile 26 are welded by the welding manipulator 2, the driving rod 22 drives the fixed surface 12 of the shell 8 to fit on the side of the door and window profile 26 and drives the support block 15 to move back to the inside of the shell 8. After the shell 8 gap of the door and window profile 26 is welded by the welding manipulator 2, the door and window profile 26 is flipped 180 degrees by the flipping assembly 3.

[0025] like Figure 8 As shown, in this embodiment, a limit ring 21 is fixedly sleeved on the surface of the rotating shaft 9, and the end of the limit ring 21 is slidably connected to the inner wall of the outer shell 8. When the outer shell 8 rotates along with the rotating shaft 9, the limit ring 21 can prevent the outer shell 8 from axial displacement on the rotating shaft 9, thereby ensuring that the outer shell 8 always remains in a suitable working position, making the operation of the positioning assembly 6 more stable and reliable.

[0026] like Figure 6 As shown, in this embodiment, a pad 20 is fixed on the fixed surface 12 of the outer shell 8, and the surface of the pad 20 is provided with anti-slip stripes. The anti-slip stripes on the surface of the pad 20 increase the friction between the outer shell 8 and the door and window profile 26, and improve the stability during fixation. When the driving rod 22 drives the fixed surface 12 of the outer shell 8 to fit the side of the door and window profile 26, the pad 20 can better fix the door and window profile 26 to prevent it from displacement during the welding process.

[0027] like Figure 6As shown, in the present embodiment, a magnet 24 is embedded on the inclined surface 13 of the outer shell 8, and the vertical surface 11 at the end of the magnet 24 is in the same vertical surface 11 as the inclined surface 13. When adjacent outer shells 8 are close to each other, the magnets 24 can attract each other, thereby enhancing the tightness of the fit between the adjacent outer shells 8. Before the door and window profiles 26 are placed, this tight fit can better maintain the stability of the ninety-degree angle formed by the vertical surfaces 11 of the adjacent outer shells 8, thereby providing a more reliable basis for the precise positioning of the door and window profiles 26. At the same time, during the welding process, it can also reduce the adverse effects on the door and window profiles 26 caused by the looseness between the outer shells 8, thereby further improving the overall stability and processing accuracy of the welding device.

[0028] like Figure 8 As shown, in this embodiment, a guide rod 17 is movably passed through the surface of the vertical plate 16, and the guide rod 17 is fixed to the inner wall of the shell 8. When the driving rod 22 rotates and drives the support block 15 to move, the vertical plate 16 can stably move along the predetermined direction under the action of the guide rod 17, thereby preventing the vertical plate 16 from deflecting or shaking during the movement.

[0029] like Figure 8 As shown, in this embodiment, a limit block 19 is fixed to the inner wall of the outer shell 8. After the support block 15 moves back to the inner wall of the outer shell 8, the support block 15 fits against the end of the limit block 19 to prevent the spring 18 from being over-compressed, thereby protecting the spring 18. Secondly, it can also ensure that the fixing surface 12 of the outer shell 8 is firmly fitted against the side of the door and window profile 26, thereby improving the stability of the door and window profile 26 during fixation.

[0030] like Figure 7 As shown, in this embodiment, a guide surface 23 is provided at the bottom of one side of the driving rod 22 close to the door and window profile 26. When the driving rod 22 approaches the top of the door and window profile 26, the guide surface 23 can guide the driving rod 22 so that the driving rod 22 can quickly fit on the top of the door and window profile 26.

[0031] like Figure 6 As shown, in this embodiment, a guide surface 10 is provided on one side of the outer shell 8 close to the door and window profile 26, and the guide surface 10 is arranged above the vertical surface 11. When the door and window profile 26 is placed, the guide surface 10 can guide the door and window profile 26 to reach the predetermined position quickly and accurately, thereby realizing the rapid placement of the door and window profile 26 and improving work efficiency.

[0032] like Figure 2 As shown, in this embodiment, the lowest point of the guide surface 10 is lower than the top of the door and window profile 26 and higher than the middle of the door and window body. The guide surface 10 can also prevent the door and window profile 26 from being welded together with the outer shell 8 during welding, thereby effectively protecting the outer shell 8, extending the service life of the equipment, reducing the maintenance cost of the equipment, and ensuring the long-term stable operation of the entire welding device.

[0033] A high-safety welding process for intelligent door and window processing, using the above-mentioned device, comprises the following steps: S1) Washing: Use a tool to clean the surface of the door and window profile 26; S2) Positioning: fixing the door and window profile 26 on the positioning assembly 6; S3) Front welding: welding the gap of the door and window profile 26 by the welding robot 2; S4) Flipping: Flip the positioning assembly 6 180 degrees by the flip assembly 3, thereby driving the door and window profile 26 to flip 180 degrees; S5) Reverse side welding: welding the gap of the door and window profile 26 by the welding robot 2; S6) Removing materials: removing the welded doors and windows from the positioning assembly 6; S7) Grinding: Grind the welding parts of doors and windows with tools; S8) Tinting: Tinting doors and windows.

[0034] Working principle: In the initial state, the inclined surfaces 13 of adjacent shells 8 are close to each other and fit together, and at this time, the vertical surfaces 11 of adjacent shells 8 form a ninety-degree angle, ready to receive the door and window profile 26; When placing the door and window profile 26, the guide surface 10 on the shell 8 is used to guide the door and window profile 26 to be placed on the support block 15. At this time, the door and window profile 26 is attached to the vertical surface 11, and its position can be quickly located. The guide surface 10 can prevent the shell 8 and the door and window profile 26 from being welded together during subsequent welding, thereby protecting the shell 8. The servo motor 27 is started, and the servo motor 27 drives the rotating shaft 9 to rotate, which drives the driving rod 22 to rotate through the rotating shaft 9. The driving rod 22 is first pressed on the top of the door and window profile 26, and the guide surface 23 at the bottom thereof helps the driving rod 22 to fit on the door and window profile 26, flattening the door and window profile 26 to avoid misplacement, thereby improving welding accuracy; When the top and inner side of the door and window profile 26 are welded, the driving rod 22 rotates in the opposite direction to move the driving rod 22 back to the inside of the shell 8. After the driving rod 22 is attached to the vertical plate 16, since a spring 18 is provided between the vertical plate 16 and the inner wall of the shell 8, the shell 8 is rotated by the elastic force of the spring 18, and the fixed surface 12 of the driving shell 8 is attached to the side of the door and window profile 26 to fix the door and window profile 26. At this time, the support block 15 is still supported on the bottom of the door and window profile 26. As the fixed surface 12 fixes the door and window profile 26 stably, the spring 18 is compressed at this time, and the driving rod 22 also drives the support block 15 through the vertical plate 16 to overcome the elastic force of the spring 18 and retract into the inside of the shell 8 until the support block 15 is attached to the end of the limit block 19. At this time, the inclined surface 13 of the shell 8 is separated, and the gap on the outside of the door and window profile 26 is exposed, and the outer gap of the door and window profile 26 is welded again by the welding manipulator 2; When the front welding of the door and window profile 26 is completed, the servo motor 4 in the flipping assembly 3 drives the support frame 5 to rotate, and the support frame 5 drives the positioning assembly 6 to rotate, so that the door and window profile 26 is flipped 180 degrees, and the back side gap of the door and window profile 26 is welded again by the welding robot 2. Hold the welded door and window with your hand, separate the fixing surface 12 of the shell 8 from the side of the door and window, and then you can directly take the door and window up and take it down.

[0035] The present invention encompasses any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the above preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details.

[0036] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
