Description

Technical Field

[0001] This invention relates to the field of automotive profile welding technology, and more specifically, to a welding device. Background Technology

[0002] The safety performance of new energy vehicles is one of the most important concerns for consumers, and the welding performance of metals directly affects the structural strength and safety of these vehicles. In the body structure of new energy vehicles, various metal profiles need to be welded together to form a robust whole. If the welding performance is poor, such as incomplete welds, detachment, or insufficient weld strength, the welded areas are prone to cracking and breakage during vehicle operation, especially under the influence of external forces such as collisions and vibrations. This compromises the integrity of the vehicle body structure, hindering the effective absorption and dispersion of collision energy and significantly increasing the risk of injury to occupants. Currently, most profiles in new energy vehicles are thin-walled components, making them extremely sensitive to heat input. Traditional welding methods, if the heat input is too high, can easily lead to burn-through, large deformation, and coarse grains and dissolution of strengthening phases in the weld joint area, forming a softening zone and making the joint strength much lower than that of the base material. If the heat input is too low, it may result in insufficient penetration or incomplete weld penetration. Existing equipment has limited ability to dynamically adjust the heat input to adapt to the different heat dissipation differences in different locations of the profiles (such as stiffeners and corners). Summary of the Invention

[0003] Based on this, in order to solve the problem that existing equipment cannot adapt to different positions of the profile by dynamically adjusting the heat input, the present invention provides a welding device, the specific technical solution of which is as follows: A welding device includes a positioning mechanism and a welding mechanism. The positioning mechanism includes a displacement seat, a disassembly frame, and multiple pressing components mounted on the disassembly frame. The disassembly frame is rotatably mounted on the displacement seat, and the pressing components are provided with a first pressing module that can be raised and lowered relative to the disassembly frame. The welding mechanism includes a track seat, a movable welding station, and a controllable welding torch rotatably mounted on the movable welding station. The movable welding station is slidably mounted on the track seat. The controllable welding torch is provided with a temperature measuring module and a temperature control module. The temperature measuring module is used to measure the temperature at the welding point on the controllable welding torch, and the temperature control module is used to adjust the temperature of the welding point according to the feedback information from the temperature measuring module.

[0004] The aforementioned welding equipment, through the combination of a disassembled frame and multiple independently liftable first pressing modules, can quickly adapt to new energy vehicle profile workpieces of different shapes and sizes. Especially for complex multi-chamber profiles or structures with stiffeners, multiple pressing points can achieve precise and uniform clamping force distribution, avoiding local stress concentration and suppressing workpiece deformation caused by improper clamping from the source, providing a stable foundation for high-quality welding. Through the temperature measurement and control modules integrated on the welding torch, a real-time feedback closed-loop control system is formed, which can directly monitor the temperature of the weld point and dynamically adjust welding parameters (such as current, voltage, or pulse frequency) to achieve precise management of heat input. This significantly improves the welding performance of the equipment, reduces the dependence on the operator's experience, and consistently produces high-quality, high-performance welded products, making it particularly suitable for the large-scale, high-standard production needs of new energy vehicle profiles.

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0020] In this invention, "first" and "second" do not represent a specific quantity or order, but are merely used to distinguish names.

[0021] like Figure 1 , Figure 2 and Figure 6 As shown, a welding device according to one embodiment of the present invention includes a positioning mechanism 1 and a welding mechanism 2. The positioning mechanism 1 includes a displacement seat 11, a disassembly frame 12, and a plurality of pressing components 13 disposed on the disassembly frame 12. The disassembly frame 12 is rotatably mounted on the displacement seat 11. The pressing components 13 are provided with a first pressing module 131 that can be raised and lowered relative to the disassembly frame 12. The welding mechanism 2 includes a track seat 21, a movable welding station 22, and a controllable welding torch 23 rotatably mounted on the movable welding station 22. The movable welding station 22 is slidably mounted on the track seat 21. The controllable welding torch 23 is provided with a temperature measuring module 231 and a temperature control module 232. The temperature measuring module 231 is used to measure the temperature at the welding point on the controllable welding torch 23, and the temperature control module 232 is used to adjust the temperature of the welding point according to the feedback information of the temperature measuring module 231.

[0022] The aforementioned welding equipment, through the cooperation of the disassembly frame 12 and multiple independently liftable first pressing modules 131, can quickly adapt to new energy vehicle profile workpieces of different shapes and sizes. Especially for complex multi-chamber profiles or structures with stiffeners, multiple pressing points can achieve precise and uniform pressing force distribution, avoiding local stress concentration and suppressing workpiece deformation caused by improper clamping from the source, providing a stable foundation for high-quality welding. Through the temperature measurement module 231 and temperature control module 232 integrated on the control welding torch 23, a real-time feedback closed-loop control system is formed, which can directly monitor the temperature of the welding point and dynamically adjust welding parameters (such as current, voltage or pulse frequency) to achieve precise management of heat input. This significantly improves the welding performance of the equipment, reduces the dependence on the operator's experience, and consistently produces high-quality, high-performance welded products, making it particularly suitable for the large-scale, high-standard production needs of new energy vehicle profiles.

[0023] like Figures 1-3 As shown, in one embodiment, the displacement seat 11 includes a first base and two displacement platforms 111 respectively fixed on both sides of the first base. A turntable 112 is rotatably mounted on the displacement platform 111, and a support bracket 113 is detachably fixed on the turntable 112. A disassembly and assembly space is formed between the two support brackets 113 on both sides for installing and fixing the disassembly and assembly frame 12. The turntable 112 is rotatably mounted on the displacement platform 111, so that the entire profile supported by the support bracket 113 (via the disassembly and assembly frame 12) can rotate 360°. At the same time, it cooperates with the welding mechanism 2 to adjust the weld seam at any position on the profile to the most ideal "flat welding" position for operation. This not only reduces the difficulty of welding operation, but also ensures that the welding gun can weld in the best posture, thereby obtaining a high-quality weld seam with uniform penetration and beautiful shape. This is especially beneficial for products with high sealing requirements such as battery pack shells that require welding in all positions.

[0024] like Figure 3 and Figure 4 As shown, in one embodiment, the disassembly frame 12 includes a frame body 121, two disassembly components 122, and multiple mounting beams 123. The two disassembly components 122 are fixed on both sides of the frame body 121, and the disassembly components 122 are mounted on the support bracket 113. A through-hole is opened at the center of the frame body 121, and multiple mounting beams 123 are spaced apart on the through-hole. Each mounting beam 123 is equipped with two opposing pressure components 13. The through-hole and mounting beam 123 provide necessary support for the profile while maximizing the welding space, allowing the controllable welding torch 23 to approach the weld point from multiple angles, including the front, side, and even obliquely below the workpiece, without obstruction. This is especially suitable for welding common internal stiffeners, reinforcing ribs, or multi-layer lap structures in new energy vehicle profiles, effectively avoiding welding blind spots caused by tooling frame interference and ensuring the integrity and quality of the weld. The pressure components 13 on the multiple mounting beams 123 are arranged facing each other, which can apply pressure from both sides of the central area of ​​the profile simultaneously. This can flatten and stably press thin-walled, large-flat profile workpieces onto the reference surface, preventing defects such as warping and wavy deformation caused by uneven pressure or insufficient support under welding heat input, thus laying the foundation for obtaining high-quality welded parts with precise dimensions.

[0025] like Figure 3 and Figure 4 As shown, in one embodiment, the clamping assembly 13 includes a mounting component, a first driving component, and a first pressing module 131. The mounting component is threaded onto the mounting beam 123, the first driving component is mounted on the mounting component, and the first pressing module 131 includes several clamping heads slidably assembled on the mounting component. The first driving component controls the lifting and lowering state of the clamping heads. By using multiple clamping heads working together, the clamping force can be distributed over a smaller area rather than concentrated at a single point. This effectively prevents damage to the surface of thin-walled profiles due to excessive clamping force and ensures a stable and reliable constraint on the local area, preventing warping or displacement caused by welding thermal deformation. The automatic lifting and lowering of the clamping heads via the first driving component automates the clamping process, ensuring good consistency between the clamping force and stroke. This avoids the problems of inconsistent force and varying force in traditional manual clamping, laying a solid foundation for the standardization and automation of the entire welding process.

[0026] like Figure 3 and Figure 4As shown, in one embodiment, the outer contour of the frame 121 is square. Two mounting plates 124 are respectively laid on both sides of the frame 121 in the width direction. The mounting plates 124 are disposed between the support bracket 113 and the through notch. Multiple first locking components 14 are provided on the mounting plates 124, and a second locking component 15 is provided on both sides of the frame 121 in the length direction. The first locking components 14 provide multi-point constraints in the width direction, and the second locking components 15 provide end-point constraints in the length direction. Together, they fix the entire frame 121 and the lower displacement seat 11 into a whole, which greatly improves the natural frequency of the entire tooling system, making its rigidity far exceed that of the frame 121 alone. When the welding mechanism 2 is running, the vibration energy from the movement of the welding torch 23, the arc force, etc., is quickly dissipated by this rigid system, which cannot cause resonance of the frame 121, thereby effectively eliminating the small associated vibrations that the profile may be subjected to, creating a crucial static environment for the stable formation of the molten pool.

[0027] In one embodiment, the structure of the first locking component 14 is the same as that of the second locking component 15. The first locking component 14 includes a connector, a second driving member, and a second pressing module 141. The connector is inserted into the mounting plate 124, the second driving member is mounted on the connector, and the second pressing module 141 is rotatably mounted on the connector. The second driving member controls the swinging state of the second pressing module 141, and a locking head 1411 is provided at one end of the second pressing module 141. Driven by the second driving member, the locking head 1411 eventually presses downward (or laterally) through swinging, which not only generates a strong pressing force in the vertical direction to prevent the profile from being lifted, but also effectively limits any horizontal displacement of the profile due to the inherent properties of the connector and the mounting plate 124 plug-in engagement and the huge friction between the locking head 1411 and the locking surface.

[0028] like Figure 4 and Figure 5 As shown, in one embodiment, the bottom surface of the locking head 1411 that abuts against the profile is a pressing surface 1412. Multiple anti-slip ribs 1413 are protruding from the pressing surface 1412. A stress groove 1414 is provided on the locking head 1411 near the pressing surface 1412, and the stress groove 1414 extends laterally through the locking head 1411. A triangular anti-slip block 1415 is provided on the side of the fixing block opposite to the pressing surface 1412. The triangular anti-slip block 1415 improves the anti-slip capability of the locking head 1411, enhances its stability, and prevents slippage. Simultaneously, the stress groove 1414 concentrates stress on the pressing surface 1412. Thus, the multiple anti-slip ribs 1413 on the pressing surface 1412 can press the profile more tightly, thereby effectively improving the anti-slip performance of the locking head 1411.

[0029] Specifically, the anti-slip rib 1413 is inclinedly disposed on the pressing surface 1412. The anti-slip rib 1413 can prevent the locking head 1411 from sliding and improve its stability when clamping the profile.

[0030] like Figure 1 and Figure 2 As shown, in one embodiment, the top of the track base 21 is provided with a guide rack 211; the movable welding station 22 includes a second base, a third drive member and an adjusting mechanical arm 221. The second base is slidably mounted on the track base 21, the third drive member is mounted on the second base, and a drive gear that meshes with the guide rack 211 is sleeved on the output end of the third drive member. One end of the adjusting mechanical arm 221 is rotatably mounted on the second base, and an adjusting welding torch 23 is rotatably mounted on the other end of the adjusting mechanical arm 221. A line pipe is provided on the side wall of the adjusting mechanical arm 221. Thus, by setting up the adjustable robotic arm 221, at least two rotational degrees of freedom are provided for the control welding torch 23. At the same time, combined with the overall movement of the moving welding station 22 on the track, the control welding torch 23 can accurately reach every welding position (such as the inside of the profile, corners, and multi-layer overlaps) of the complex structure of the profile with the optimal spatial posture, easily achieving ideal welding positions such as flat welding and horizontal welding, thereby significantly improving the weld formation quality and welding accessibility. By setting up the pipeline, it is easy to integrate and store all pipelines such as welding cables, control lines, and protective gas lines in the pipeline inside the robotic arm. This not only makes the overall appearance of the equipment neat, but more importantly, it avoids the pipelines from getting tangled, pulled, or worn with the equipment or workpiece during complex movements, greatly improving the safety and reliability of the equipment in long-term operation, while reducing the impact of pipeline interference on the posture accuracy of the control welding torch 23.

[0031] like Figure 6 and Figure 7As shown, in one embodiment, the controllable welding torch 23 includes a torch body 233 and a welding torch 234 connected to the torch body 233. A temperature measuring module 231 is installed on one side of the torch body 233. The temperature measuring module 231 includes a temperature measuring structure 2311 and a temperature controller 2312. A liquid carbon dioxide tank 235 is provided inside the torch body 233. The liquid carbon dioxide tank 235 is connected to one end of a temperature control module 232 hinged to the welding torch 234 through a delivery pipe 236. A nozzle 237 is welded to the other end of the temperature control module 232. An inner cavity is provided inside the temperature control module 232. An insulation wall 238 is provided between the inner cavity and the temperature control module 232. A solenoid valve 239 is installed at the connection between the temperature control module 232 and the nozzle 237. The solenoid valve 239 is used to control the opening and closing of the nozzle 237. With the temperature measurement module 231, the actual temperature of the solder joint can be captured in real time and in situ, providing the most direct and fastest feedback signal to the control system. With the liquid carbon dioxide tank 235 connected to the temperature control module 232 via the delivery pipe 236, the liquid carbon dioxide vaporizes and absorbs heat when sprayed, achieving a strong local instantaneous cooling effect. When the temperature measurement module 231 detects that the heat input is too high and the temperature of the molten pool exceeds the ideal range, the system can instruct the solenoid valve 239 to open, and spray precisely into the area behind the solder joint through the nozzle 237 to achieve rapid cooling. With the solenoid valve 239 directly integrated into the end of the temperature control module 232, the path from the signal command to the coolant spray is shortened to the maximum extent, achieving rapid response.

[0032] Preferably, the insulation wall 238 is made of rock wool, and the nozzle 237 is made of wooden tubing. This improves durability and operational safety.

[0033] Specifically, the temperature measuring structure 2311 is a temperature measuring gun.

[0034] like Figure 8 and Figure 9As shown, in one embodiment, the welding equipment further includes a conveying mechanism 3 and a handling mechanism 4. The conveying mechanism 3 includes a plurality of conveyor belts 31 arranged at intervals. The handling mechanism 4 includes a gantry frame 41, a sliding component 42, and a first clamping component 43 and a second clamping component 44 for clamping profiles. The top of the gantry frame 41 is provided with a guide rail. The sliding component 42 is slidably mounted on the guide rail. The sliding component 42 is provided with a first transverse rail and a second transverse rail on both sides. The first clamping component 43 and the second clamping component 44 are slidably mounted on the first transverse rail and the second transverse rail, respectively. The conveying mechanism 3 forms a continuous material flow, which can automatically and orderly transport profiles from the previous process to the welding station, eliminating the intermittent pauses of traditional manual handling and laying the logistics foundation for the automation of the entire line. The gantry 41 of the handling mechanism 4 spans the conveying mechanism 3 and the positioning mechanism 1. The sliding component 42 can move along the guide rail to the top of the conveyor belt 31. After the first clamping component 43 or the second clamping component 44 grabs the profile, it is moved to the top of the frame 121 for placement and fixation, realizing the unmanned automation of the entire process and significantly improving the production cycle and efficiency.

[0035] Preferably, the guide rail, the first transverse rail, and the second transverse rail are all arranged in a horizontal direction, wherein the first transverse rail and the second transverse rail are parallel to each other and both are perpendicular to the guide rail.

[0036] like Figure 8 and Figure 9 As shown, the sliding assembly 42 further includes a slide table 421, a fourth driving member, and two brackets 422 connected to both sides of the slide table 421. The slide table 421 is slidably mounted on the guide rail. The fourth driving member is mounted on the slide table 421 and used to control the sliding state of the slide table 421 on the guide rail. The first and second transverse rails are respectively protruding from the surfaces of the two brackets 422 on both sides. The two brackets 422 form a symmetrical lever arm structure extending from the central slide table 421 to both sides, so that the weight of the first and second clamping assemblies 44 and the profiles they clamp are evenly transmitted to the central slide table 421 through the brackets 422 on both sides, and finally borne by the guide rail. This perfectly balances the overturning moment that may be generated due to load eccentricity, greatly enhances the rigidity and stability of the system during high-speed start-up, shutdown, and operation, and effectively prevents shaking and impact.

[0037] Furthermore, the structure of the first clamping component 43 is the same as that of the second clamping component 44.

[0038] like Figure 9As shown, specifically, the first clamping assembly 43 includes a lifting vertical frame 431 and a first connecting bracket 432 and a second connecting bracket 433 stacked crosswise at the bottom of the lifting vertical frame 431. A linear module is installed inside the lifting vertical frame 431, and a connecting seat is slidably mounted on the linear module. The connecting seat is slidably mounted on a first transverse rail. A fifth driving component for controlling the lifting state of the lifting vertical frame 431 is installed on the top of the lifting vertical frame 431. Two clamping members 434 are slidably connected to both sides of the first connecting bracket 432, forming a clamping gap between the two clamping members 434 for clamping the profile. Multiple suction cups 435 are fixed at intervals on the second connecting bracket 433, and suction cups 435 are also fixed to the side wall of the first connecting bracket 432. The parallel use of mechanical clamping and vacuum adsorption provides redundancy. Even if one system temporarily fails, the other system can still provide the necessary holding force, greatly improving the safety of the handling process. At the same time, this composite design enables reliable handling of various irregular cross-sections, hollow structures, or profiles with high surface precision requirements, making it applicable to a wide range of applications.

[0039] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0040] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
