Description

Technical Field

[0001] This invention relates to the field of aluminum welding technology, and in particular to an automatic aluminum welding machine. Background Technology

[0002] Automatic aluminum welding equipment is a specialized automated welding system designed for aluminum and aluminum alloy materials. Through the synergistic effect of mechanical structure, electrical control system, and welding process, it achieves automated, high-precision, and high-efficiency aluminum welding operations. The automatic aluminum welding equipment includes a frame, intelligent casting table, welding robot / robotic arm, automatic / semi-automatic electric arc / plasma arc welding machine, and guide rail slides, enabling precise movement control of the workpiece and welding torch. The structure can be referenced in Chinese Invention Patent Publication No. CN111151926B, entitled "Automatic Welding Device for Aluminum Brackets," and Chinese Utility Model Patent Publication No. CN209792939U, entitled "Automatic Welding Machine for Aluminum Plates." Current intelligent aluminum welding equipment requires the shape of the weld and the welding torch route to be determined before welding can begin, in order to carry out batch continuous production of aluminum materials of the same specification. If the specifications of the aluminum material to be welded change or the weld type changes during the processing, the equipment can only switch to the existing welding program, but often cannot be fully adapted to the welding requirements. The equipment needs to be re-adjusted and the route planned, which affects production efficiency and welding accuracy. Summary of the Invention

[0008] And a laser welding module whose movement is controlled by the driven shaft according to the coupling curve, the laser welding module being started and stopped by the coupling controller.

[0009] Preferably, the automatic aluminum feeding line includes a track, a moving platform, and an aluminum gripping robot. The drive shaft includes a feeding motor. Both the aluminum gripping robot and the feeding motor are connected to a coupling controller.

[0010] Preferably, the laser welding module includes a linear guide rail, a movable base, and a laser welding gun. The driven shaft includes an adjusting motor. Both the adjusting motor and the laser welding gun are connected to a coupling controller. The adjusting motor controls the movable base to slide along the linear guide rail through another set of transmission components. The linear guide rail is perpendicular to the feeding axis of the automatic aluminum feeding line. The laser welding gun is mounted on the movable base.

[0011] Preferably, the laser welding module further includes a base and a first annular frame. The first annular frame is rotatably mounted on the base. The rotation axis of the first annular frame coincides with the feeding axis of the automatic aluminum feeding line. The first annular frame is provided with a gear plate. The driven shaft also includes a rotary motor. The rotary motor is mounted on the base and connected to a coupling controller. The rotary motor drives the first annular frame to rotate through gear meshing with the gear plate. A linear guide rail is arranged radially on the first annular frame. An adjustment motor is mounted on the first annular frame.

[0012] Preferably, the first annular frame has two or more locking holes along the circumference, and the linear guide rail is locked to the locking holes.

[0013] Preferably, the weld shape scanning module includes an angle and orientation adjustment frame and a scanning camera. The scanning camera is mounted on the angle and orientation adjustment frame and is oriented toward the automatic aluminum feeding line. The scanning camera is connected to a coupling controller.

[0014] Preferably, the angle and orientation adjustment frame includes a second ring frame, an orientation adjustment seat, and an angle adjustment seat.

[0015] Preferably, two or more position adjustment seats are slidably arranged inside the arc-shaped guide rail.

[0016] Preferably, two or more weld shape scanning modules scan the weld shape of the aluminum material from different angles. The coupling controller generates a set of coupling curves for each weld shape scanning module based on the coordinate information recorded by each module. Each set of coupling curves is sent to a driven axis, and each driven axis controls the movement of a laser welding module.

[0017] Preferably, the assembly also includes a frame, and the weld shape scanning module and the laser welding module are detachably mounted on the frame, with two or more laser welding modules spaced apart along the feeding direction of the automatic aluminum feeding line.

[0018] The beneficial effects of this invention are as follows: An automatic aluminum welding machine operates by using a drive shaft to continuously feed aluminum material at a preset speed via an automatic aluminum feeding line. First, a weld shape scanning module scans the weld shape of the currently passing aluminum material in real time and generates coordinates.

[0026] To explain in detail the technical content, objectives, and effects of the present invention, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0027] Please refer to Figures 1 to 5 As shown, an automatic aluminum welding machine of the present invention includes:

[0028] An automatic aluminum material feeding line 2 whose conveying speed is controlled by a drive shaft 1;

[0029] Weld seam shape scanning module 3 located at the front end of the automatic aluminum feeding line 2;

[0030] A coupling controller that generates a coupling curve based on information sent by the drive shaft 1 and the weld shape scanning module 3;

[0031] And a laser welding module 5 whose movement is controlled by the driven shaft 4 according to the coupling curve, and the laser welding module 5 is controlled to start and stop by the coupling controller.

[0032] The beneficial effects of this invention are as follows: It eliminates the need to determine the weld shape and welding torch path before welding begins. Instead, real-time coupling allows the welding torch to adjust its path based on the weld shape and position. Even if the aluminum material specifications or weld type change, there is no need to stop the equipment for debugging or write new control programs, thus ensuring production efficiency. While maintaining processing accuracy, it enables continuous, efficient, and fully automated welding operations, making it particularly suitable for batch production of materials of different specifications, which helps increase production capacity while reducing costs. The specific working principle is as follows: The automatic aluminum welding machine utilizes a drive shaft 1 to drive an automatic aluminum feeding line 2 to continuously feed the aluminum material to be welded at a preset speed. First, a weld shape scanning module 3 scans the weld shape of the currently passing aluminum material in real time and generates coordinates. Then, the drive shaft 1 and the weld shape scanning module 3 send data to a coupling controller in real time. The coupling controller generates a corresponding coupling curve based on the weld coordinates and the feeding speed, coupling the driven shaft 4. The driven shaft 4 only needs to control the laser welding module 5 to move according to the coupling curve to complete the automated welding operation.

[0033] In an optional embodiment, the automatic aluminum feeding line 2 includes a track 21, a moving platform 22, and an aluminum gripping robot 23. The drive shaft 1 includes a feeding motor 11. Both the aluminum gripping robot 23 and the feeding motor 11 are connected to a coupling controller. The feeding motor 11 controls the moving platform 22 to slide along the track 21 through a set of transmission components 111. The aluminum gripping robot 23 is mounted on the moving platform 22.

[0034] The effect of the above optional embodiment is as follows: During operation, the aluminum material gripping robot 23 grips the aluminum material to be welded and keeps it stable at a preset height. The feeding motor 11 is started and drives the moving platform 22 to move along the track 21 at a preset speed through the transmission component 111, so that the aluminum material to be welded passes through the weld shape scanning module 3 and the laser welding module 5 in sequence. The weld shape scanning module 3 scans the shape and size of the aluminum material weld and records the weld information in the form of coordinates. The coupling controller can calculate the welding path and method corresponding to the simulated laser welding module 5 based on the coordinates. The driven shaft 4 controls the movement of the laser welding module 5 according to the simulation relationship, and the coupling controller controls the laser welding module 5 to start and stop welding.

[0035] In an optional embodiment, the laser welding module 5 includes a linear guide rail 51, a movable seat 52, and a laser welding gun 53. The driven shaft 4 includes an adjusting motor 41. Both the adjusting motor 41 and the laser welding gun 53 are connected to a coupling controller. The adjusting motor 41 controls the movable seat 52 to slide along the linear guide rail 51 through another set of transmission components 111. The linear guide rail 51 is perpendicular to the feeding axis of the automatic aluminum feeding line 2. The laser welding gun 53 is mounted on the movable seat 52.

[0036] The advantages of the above optional embodiments are as follows: During operation, the coupling controller sends corresponding commands to control the adjusting motor 41 and the laser welding gun 53. The adjusting motor 41 drives the moving seat 52 to translate on the linear guide rail 51 through the transmission component 111, thereby enabling the laser welding gun 53 to move along the path of the simulated weld shape for real-time and precise welding. Here, the installation angle of the linear guide rail 51 can be flexibly adjusted according to different welding methods to ensure comprehensive and precise welding of the weld.

[0037] In an optional embodiment, the laser welding module 5 further includes a base 54 and a first annular frame 55. The first annular frame 55 is rotatably mounted on the base 54. The rotation axis of the first annular frame 55 coincides with the feeding axis of the automatic aluminum feeding line 2. The first annular frame 55 is provided with a gear disk 551. The driven shaft 4 further includes a rotary motor 42. The rotary motor 42 is mounted on the base 54 and is connected to a coupling controller. The rotary motor 42 drives the first annular frame 55 to rotate through gear 421 meshing with the gear disk 551. A linear guide rail 51 is arranged radially on the first annular frame 55. An adjusting motor 41 is mounted on the first annular frame 55.

[0038] The advantages of the above optional embodiments are as follows: The base 54 is set to support the first ring frame 55 that can rotate in the vertical plane. The first ring frame 55 serves as the mounting base for the linear guide rail 51. The rotary motor 42 drives the first ring frame 55 to rotate through the meshing of the gear 421 and the gear disk 551 according to the coupling curve. The linear guide rail 51 located on the first ring frame 55 rotates accordingly, thereby changing the angle and orientation of the laser welding gun 53. At the same time, the adjusting motor 41 drives the moving seat 52 to translate on the linear guide rail 51 through the transmission component 111, so that the laser welding gun 53 moves along the path of the simulated weld shape for real-time and precise welding.

[0039] In an optional embodiment, the first ring frame 55 is provided with two or more locking holes 552 along the circumferential direction, and the linear guide rail 51 is locked to the locking holes 552.

[0040] The advantages of the above optional embodiments are: the lock hole 552 is used to install the linear guide rail 51, and multiple laser welding guns 53 can be flexibly installed in different positions to meet different welding needs.

[0041] In an optional embodiment, the weld shape scanning module 3 includes an angle and orientation adjustment frame 31 and a scanning camera 32. The scanning camera 32 is mounted on the angle and orientation adjustment frame 31 and faces the automatic aluminum feeding line 2. The scanning camera 32 is connected to a coupling controller.

[0042] The effect of the above optional embodiments is that the scanning camera 32 can adjust the angle and orientation through the angle and orientation adjustment frame 31, thereby adapting to the scanning needs of aluminum materials of different sizes and specifications and welds in different positions.

[0043] In an optional embodiment, the angle and orientation adjustment frame 31 includes a second annular frame 311, an orientation adjustment seat 312, and an angle adjustment seat 313. The center line of the second annular frame 311 coincides with the feeding axis of the automatic aluminum feeding line 2. The second annular frame 311 is provided with an arc-shaped guide rail 3111. The orientation adjustment seat 312 slides along the arc-shaped guide rail 3111 under the drive of the moving motor 3121. The angle adjustment seat 313 flips on the orientation adjustment seat 312 under the drive of the flipping motor 3131. The scanning camera 32 is mounted on the angle adjustment seat 313.

[0044] The advantages of the above optional embodiments are as follows: the second annular frame 311 is set as the mounting base of the orientation adjustment seat 312. The orientation adjustment frame slides along the arc-shaped guide rail 3111 of the second annular frame 311 via the moving motor 3121, thereby changing the lens orientation of the scanning camera 32. At the same time, the tilting motor 3131 is used to adjust the shooting angle of the scanning camera 32, so that different types of welds can be photographed from different angles.

[0045] In an optional embodiment, two or more position adjustment seats 312 are slidably disposed within the arc-shaped guide rail 3111.

[0046] The effect of the above optional embodiments is that: for different types and quantities of welds, the number of scanning cameras 32 needs to be increased to take pictures from different angles, thereby realizing a comprehensive scan of the welds, which facilitates subsequent one-time welding and ensures the welding accuracy of each group of welds.

[0047] In an optional embodiment, two or more weld shape scanning modules 3 scan the weld shape of the aluminum material from different angles. The coupling controller generates a set of coupling curves corresponding to the coordinate information recorded by each weld shape scanning module 3. Each set of coupling curves is sent to a driven axis 4, and each driven axis 4 controls the movement of a laser welding module 5.

[0048] The advantages of the above optional embodiments are as follows: For different types and quantities of welds, the number of weld shape scanning modules 3 needs to be increased. For a single weld, two or more weld shape scanning modules 3 can be used to scan from different angles. For multiple different welds, a mode in which multiple weld shape scanning modules 3 scan one-to-one with the welds can be used. In this way, the coupling controller will generate different simulation curves for the information of each weld and send them to the corresponding driven axis 4. Each driven axis 4 only needs to control the movement of one set of laser welding modules 5. Multiple sets of laser welding modules 5 cooperate to perform all-round complete welding.

[0049] In an optional embodiment, a frame 6 is also included, and the weld shape scanning module 3 and the laser welding module 5 are detachably mounted on the frame 6, with two or more laser welding modules 5 spaced apart along the feeding direction of the automatic aluminum feeding line 2.

[0050] The advantages of the above optional embodiments are: multiple sets of laser welding modules 5 can be arranged at preset intervals as needed to perform multiple welding for welds that cannot be completely welded in one go, and parameters such as the starting position can be selected independently in accordance with the welding type.

[0051] Please refer to Figures 1 to 5 As shown, Embodiment 1 of the present invention is: an automatic aluminum welding machine, comprising:

[0057] The laser welding module 5 includes a linear guide rail 51, a movable seat 52, a laser welding gun 53, a base 54, and a first annular frame 55. The driven shaft 4 includes an adjusting motor 41 and a rotary motor 42. Both the adjusting motor 41 and the laser welding gun 53 are connected to a coupling controller.

The linear guide rail 51 is perpendicular to the feeding axis of the automatic aluminum feeding line 2. The laser welding gun 53 is mounted on the movable seat 52. The first annular frame 55 is rotatably mounted on the rotary support bearing of the base 54. The rotation axis of the first annular frame 55 coincides with the feeding axis of the automatic aluminum feeding line 2. A gear disk 551 is provided on the outer ring of the first annular frame 55. The rotary motor 42 is mounted on the base 54 and is connected to the coupling controller. The rotary motor 42 drives the first annular frame 55 to rotate through gear 421 meshing with the gear disk 551. The linear guide rail 51 is arranged radially on the first annular frame 55, and the adjusting motor 41 is mounted on the first annular frame 55. The first ring frame 55 has an opening in the middle for the automatic aluminum feeding line 2 to pass through.

[0058] The weld shape scanning module 3 includes an angle and orientation adjustment frame 31 and a scanning camera 32. The scanning camera 32 is mounted on the angle and orientation adjustment frame 31 and faces the automatic aluminum feeding line 2. The scanning camera 32 is connected to a coupling controller. The angle and orientation adjustment frame 31 includes a second annular frame 311, an orientation adjustment seat 312, and an angle adjustment seat 313. The centerline of the second annular frame 311 coincides with the feeding axis of the automatic aluminum feeding line 2. The second annular frame 311 has an arc-shaped guide rail 3111 along its circumference. The orientation adjustment seat 312 slides along the arc-shaped guide rail 3111 under the drive of a moving motor 3121. The angle adjustment seat 313 flips on the orientation adjustment seat 312 under the drive of a flipping motor 3131. The scanning camera 32 is mounted on the angle adjustment seat 313. The middle part of the second annular frame 311 also has an opening for the automatic aluminum feeding line 2 to pass through.

[0059] The first ring frame 55 has two or more arc-shaped locking holes 552 along its circumference, and the linear guide rail 51 is locked to the locking holes 552.

[0060] A coupling controller is a controller with a coupled control system. In this embodiment, the controller is a PLC controller. The coupling control system uses a commonly used electronic cam system. Its principle is: through digital modeling and real-time control algorithms, the driven shaft 4 (or actuator) follows the active shaft 1 (or virtual master shaft) along a preset trajectory without a physical cam. The core principle can be summarized as three parts: "trajectory planning - real-time mapping - closed-loop control". Trajectory planning is the core of constructing the electronic cam, which is the virtual cam curve. The virtual cam curve is used to define the correspondence between the motion of the driven shaft 4 and the motion of the active shaft 1. Commonly used trajectory curves include sine curves, polynomial curves, and modified trapezoidal curves. Real-time mapping dynamically associates the master shaft and the driven shaft. The electronic cam system calculates in real time to map the current position of the active shaft 1 to the target position of the driven shaft 4, achieving dynamic synchronization between the two. This includes the acquisition of the position of the active shaft 1, table lookup and interpolation calculation, and motion command output. Closed-loop control ensures that the actual motion trajectory matches the target trajectory. Electronic cam systems typically incorporate a closed-loop control mechanism: position feedback of the driven shaft 4, with the encoder acquiring the actual position of the driven shaft 4 in real time; error compensation, calculating the deviation between the target and actual positions, and adjusting the drive output through algorithms such as PID control to correct the error; and dynamic adaptability, where some advanced systems can adjust the cam curve parameters in real time based on load changes and speed fluctuations to improve robustness. In this embodiment, both the drive shaft 1 and the driven shaft 4 are equipped with electronic cam coupling modules. Before welding, a coordinate system is established. The electronic cam system generates a mapped coupling curve (i.e., a virtual cam curve) in real time based on the feeding parameters of the feeding motor 11 and the weld position coordinates recorded by the scanning camera 32 after scanning the weld shape of the aluminum material to be welded. The adjusting motor 41 and the rotary motor 42 adjust the angle and distance of the laser welding module 5 relative to the aluminum material in the vertical circumferential direction according to the coupling curve, thereby welding according to the virtual contour curve. After one piece of aluminum material is welded, all components are reset, awaiting the next piece of aluminum material to be fed. The controller, combined with algorithm training, can accurately identify different types of welds and autonomously learn and judge various welding operation scenarios through its self-learning function, thereby performing corresponding welding operations in a targeted manner and achieving intelligent operation.

[0061] Please refer to Figures 1 to 5As shown, Embodiment 2 of the present invention is based on Embodiment 1: two or more weld shape scanning modules 3 scan the weld shape of the aluminum material from different angles. The coupling controller generates a set of coupling curves corresponding to the coordinate information recorded by each weld shape scanning module 3. Each set of coupling curves is sent to a driven axis 4, and each driven axis 4 controls the movement of a laser welding module 5. In this structure, the active axis 1 is coupled with multiple driven axes 4, which can simultaneously control the movement of multiple laser welding modules 5. It can be applied to processing scenarios where there are multiple welds (such as two fillet welds) after splicing two or more parts, or where welding cannot be completed on a part at one time using a single welding tool.

[0062] Please refer to Figures 1 to 5 As shown, Embodiment 3 of the present invention, based on Embodiment 1, further includes a frame 6, with the weld shape scanning module 3 and laser welding module 5 detachably mounted on the frame 6. Two or more laser welding modules 5 are spaced apart along the feeding direction of the automatic aluminum feeding line 2. For the assembly and welding of long aluminum materials, the system can automatically generate two welding routes. Then, the front laser welding module 5 welds from the middle of the aluminum material towards the rear end (the end opposite to the feeding direction), and the rear laser welding module 5 welds from the beginning of the aluminum material (the end facing the feeding direction) towards the middle. This ensures uniform heating of the aluminum material, preventing deformation and burn-through due to excessively high local temperatures.

[0063] Please refer to Figures 1 to 5 As shown, in Embodiment 4 of the present invention, based on Embodiment 1, the number of tracks 21 is two or more, and each track 21 is equipped with a mobile platform 22 corresponding to an aluminum material gripping robot 23. The function of setting two or more aluminum material gripping robots 23 is to ensure the feeding accuracy and alignment accuracy of aluminum materials by coordinating the gripping of aluminum materials according to their quantity or shape.

[0064] In summary, compared to existing technologies, the automatic aluminum welding machine of this invention eliminates the need to determine the weld shape and plan the welding torch path before welding begins. Instead, it uses real-time coupling to allow the welding torch to adjust its path based on the weld shape and position. Even if the aluminum specifications or weld type change, there is no need to stop the machine for debugging or write new control programs, thus ensuring production efficiency. This invention achieves continuous, efficient, and fully automated welding operations while maintaining processing accuracy requirements. It also boasts good compatibility and is particularly suitable for mass production of materials of different specifications, thereby increasing production capacity while reducing costs.
