[0002] In building decoration, furniture manufacturing, and municipal engineering, the welding of door frames, railings, window frames, and other metal structural components is a significant process. Traditional welding methods mainly employ manual arc welding or semi-automatic welding machines, with operators holding welding torches to complete the welding. However, workers are exposed to high temperatures, high light radiation, and fumes for extended periods, resulting in high labor intensity and adverse health effects. Manual operation makes it difficult to achieve continuous and efficient welding, and it cannot meet the demands of mass production. Door frames, railings, and other metal profile frame components are mostly slender workpieces, involving various welding methods such as fillet welding, butt welding, and round pipe welding, making it difficult to guarantee consistency and high efficiency through manual methods.

[0003] In recent years, laser welding technology has been increasingly applied to the production of metal profile frame components due to its small heat-affected zone, narrow weld seam, high welding speed, and high degree of automation. However, most existing laser welding equipment is complex in design and developed for specific parts, making it difficult to apply to workpieces of various specifications and shapes such as door frames and railings. It suffers from problems such as insufficient flexibility, inconvenient workpiece clamping, and poor weld seam tracking accuracy.

[0004] Therefore, this application proposes an automated laser welding device to solve the above-mentioned problems. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. All directional indicators (such as up, down, left, right, front, back, etc.) in the present utility model are only used to explain the relative positional relationship and movement of each component in a certain posture (as shown in the accompanying drawings). If the specific posture changes, the directional indicator will also change accordingly.

[0027] This embodiment provides a laser automated welding device for welding profile frame components. In this example, the profile frame component is a door frame, railing, or window frame. The profile frame component includes an outer frame 7 and a mullion 8. The outer frame 7 has a long side and a short side, and the mullion 8 is fixed inside the outer frame 7.

[0028] like Figures 1-5 As shown, the welding equipment includes a base 1, a clamping mechanism 2, a positioning mechanism 29, a five-axis cantilever mechanism 4, and a control mechanism 5. The clamping mechanism 2 includes a first linear guide module 21 and a second linear guide module 22. Both the first linear guide module 21 and the second linear guide module 22 are existing structures, each containing a servo motor, a lead screw, and a sliding component. The sliding component is threadedly connected to the lead screw. The servo motor drives the lead screw to rotate. The first linear guide module 21 is fixed to the top of the base 1. The first linear guide module 21 and the second linear guide module 22 are arranged perpendicularly, and the first linear guide module 21 drives the second linear guide module 22 to translate. The second linear guide module 22 is provided with a clamping structure for clamping and fixing. In this example, the profile frame component has two first linear guide rail modules 21 and two second linear guide rail modules 22, determined by the number of mullions 8. The mullions 8 are correspondingly set with the second linear guide rail modules 22, and the first linear guide rail modules 21 are matched with the second linear guide rail modules 22. The positioning mechanism 29 is fixed on the machine base 1 and located at one end of the clamping mechanism 2, used to position one end of the profile frame component to be welded. The five-axis cantilever mechanism 4 is located on the side of the clamping mechanism 2 and a laser welding gun 6 is mounted on it. The five-axis cantilever mechanism 4 drives the laser welding gun 6 to weld the profile frame component on the clamping mechanism 2. The control mechanism 5 is fixed on the machine base 1 and is used to control the output of the clamping mechanism 2 and the five-axis cantilever mechanism 4.

[0029] Furthermore, such as Figures 2-3 As shown, the clamping structure includes an inner positioning block 23, a first clamping cylinder 24, and a second clamping cylinder 25. The inner positioning block 23 is fixedly mounted on one end of the second linear guide module 22. The first clamping cylinder 24 matches the inner positioning block 23 and is used to clamp one long side of the profile frame component. The second clamping cylinder 25 is located on the outside of the other long side of the profile frame component and is used to position the other long side of the profile frame component. Specifically, the positioning mechanism 29 positions one end of the outer frame 7 of the profile frame component. According to the position of the inner mullion 8 of the outer frame 7, the first linear guide module 21 adjusts the position of the second linear guide module 22. Then, the inner positioning block 23 fits against the inner side of one long side of the outer frame 7 to position one long side of the outer frame 7. Then, the first clamping cylinder 24 clamps the long side, and the second clamping cylinder 25 is positioned on the outer side of the other long side of the outer frame 7, thereby clamping and limiting the width of the outer frame 7.

[0030] Furthermore, such as Figures 2-3As shown, the fixture structure also includes a side positioning block 26 and a third clamping cylinder 27. The third clamping cylinder 27 cooperates with the side positioning block to clamp the mullion 8. There are at least two sets of side positioning blocks 26 and third clamping cylinders 27. One set is fixed to one end of the second linear guide module 22 near the inner positioning block 23, and the other set is slidably disposed on the second linear guide module 22. In this example, there are two mullions 8. Each second linear guide module 22 also has two sets of side positioning blocks 26 and third clamping cylinders 27, near the inner positioning block 23. The side positioning block 26 of the third linear guide module 22 positions one side of the mullion 8, and works with the third clamping cylinder 27 to fix one end of the mullion 8. Then, the sliding member on the second linear guide module 22 drives another set of side positioning blocks 26 and the third clamping cylinder 27 to move to the other end of the mullion 8. The side positioning block 26 and the third clamping cylinder 27 clamp and fix the other end of the mullion 8, thereby fixing the mullion 8. The telescopic ends of the first clamping cylinder 24, the second clamping cylinder 25 and the third clamping cylinder 27 are all fixed with clamping blocks to facilitate clamping and fixing. At the same time, a control panel 28 is provided at one end of the second linear guide module 22. The control panel 28 is provided with control buttons and is used to control the opening and closing of the first clamping cylinder 24, the second clamping cylinder 25 and the third clamping cylinder 27.

[0031] Furthermore, such as Figures 2-3 As shown, the positioning mechanism 29 includes a frame 31, on which a plurality of positioning posts 32 are provided. In this example, three positioning posts 32 are provided and are evenly distributed. One of the positioning posts 32 is located at one corner of the profile frame member. This positioning post 32 is located on the inner side of one corner of the outer frame 7 and is used to position one corner of the outer frame 7. At the same time, the positioning corner is on the same side as the fixed inner positioning block 23. The three positioning posts 32 can position one short side of the outer frame 7. Meanwhile, the outermost positioning post 32 can slide and adjust on the frame 31. The positioning posts 32 on the positioning mechanism 29 cooperate with the inner positioning block 23 of the clamping structure, the first clamping cylinder 24 and the second clamping cylinder 25 to position the outer frame 7.

[0032] Furthermore, such as Figures 4-5As shown, the five-axis cantilever mechanism 4 includes a sliding frame 41, which slides along the X-axis direction of the base 1. Specifically, the base 1 is provided with multiple X-axis slide rails 42. The slider on the sliding frame 41 slides along the X-axis slide rails 42. A drive motor 43 is mounted on the sliding frame 41, and a drive gear 44 is fixed to the output end of the drive motor 43. A rack and pinion 45 is fixed on the base 1, and the drive gear 44 meshes with the rack and pinion 45. The drive motor 43 drives the drive gear 44 to mesh with the rack and pinion 45, thereby driving the sliding frame 41 to move along the X-axis direction. A Y-axis servo slide module 46 is fixed on the sliding frame 41 to realize movement in the Y-axis direction. The sliding part of the Y-axis servo slide module 46 is fixed with a Z-axis. The servo slide module 47 enables movement in the Z-axis direction. The sliding part of the Z-axis servo slide module 47 is fixed with a horizontal rotation structure 48. The rotating part of the horizontal rotation structure 48 is fixed with a vertical rotation mechanism 49. The rotating part of the vertical rotation mechanism 49 is fixed with a laser welding gun 6, thereby driving the laser welding gun 6 to adjust in the X-axis, Y-axis, and Z-axis directions, as well as in the horizontal and vertical planes, to complete the multi-dimensional welding action. In this example, the Y-axis servo slide module 46 and the Z-axis servo slide module 47 are existing structures, each equipped with a servo motor and a lead screw. The sliding part is threadedly connected to the lead screw. Both the horizontal rotation structure 48 and the vertical rotation mechanism 49 use servo motors to drive the rotating parts.

[0033] like Figure 1 As shown, the control mechanism 5 includes a vertical frame 51, on which a display 52, a barcode scanner 53, a keyboard tray 54, and a folder 55 are fixed. The display 52 is used to display operating system information, the barcode scanner 53 is used to read the waybill information and automatically input the waybill size data into the control system, the keyboard tray 54 is used to place the keyboard and mouse to facilitate system operation and data input, and the folder 55 is used to place paper waybills for easy viewing and verification.

[0034] Its workflow is as follows:

[0035] The equipment control system automatically inputs the corresponding dimensional parameters of the product into the control system (or manually inputs them) based on the product data information read from the paper manifest by the scanner 53. After verifying all data and parameters, the start button is pressed. Each axis moves to the predetermined position according to the set parameters. Then, the workpiece outer frame 7 is fitted onto the equipment fixture, with the short side of the outer frame 7 aligning with the positioning post 32 and one long side aligning with the inner positioning block 23. After confirming that it is correct, the outer frame 7 clamping execution button is pressed to clamp and fix the outer frame 7. Then, the workpiece mullion 8 is placed in and aligned with the side positioning block 26. After confirming that it is correct, the mullion 8 clamping execution button is pressed to clamp and fix the mullion 8. The second clamping cylinder on the other long side of the outer frame 7 is also linked to eliminate the gap between the outer frame 7 and the mullion 8. After confirming that the workpiece assembly is correct, the welding execution button is pressed. Each servo axis works together to complete the welding of each weld point on the workpiece. After welding is completed, the welding torch returns to the zero point, and each clamping cylinder is released for easy removal of the workpiece. A new workpiece is placed in, and this process is repeated. Based on the workpiece setting parameters, the workpiece is positioned and fixed in size. Then, the system drives the five-axis cantilever mechanism 4 to move the laser welding gun 6 along the welding path according to the parameters. The high-energy beam generated by the laser is focused on the weld seam of the workpiece by the laser welding gun 6, causing it to fuse at high temperature.

[0036] The overall structure of this utility model can CNC position and fix the profile frame components, which is convenient and flexible, avoids the errors caused by manual measurement, and completes high-precision automated welding through CNC programming, thereby improving production efficiency and ensuring the welding quality of the profile frame components.
