Description

Technical Field

[0001] This invention relates to the field of sheet metal cabinet welding platform technology, specifically a sheet metal cabinet welding platform with clamping function. Background Technology

[0002] In the sheet metal cabinet welding process, the stability and positioning accuracy of the fixing fixture directly determine the welding quality. Currently, existing sheet metal cabinet welding platforms generally have many shortcomings: most adopt a single clamping structure, which can only achieve basic fixation, and the clamping force cannot be precisely controlled, which can easily lead to deformation of the sheet metal cabinet or loosening of the clamp; during the welding process, high temperatures will cause thermal expansion and deformation of the sheet metal cabinet.

[0003] Existing platforms lack effective thermal deformation compensation mechanisms, only passively correcting deviations and failing to actively counteract deformation offsets. This leads to weld position deviations and affects processing accuracy. During corner welding, clamping components easily obstruct the welding position, requiring frequent tooling adjustments, resulting in cumbersome and inefficient operations. Some platforms lack multi-dimensional fixing structures, exhibiting poor adaptability and failing to meet the processing needs of sheet metal cabinets of different specifications. These problems not only reduce the efficiency and quality of sheet metal cabinet welding but also increase the labor intensity of operators, making them unsuitable for large-scale, high-precision welding production. Therefore, there is an urgent need for a sheet metal cabinet welding platform with clamping function that can solve the above pain points. Summary of the Invention

Detailed Implementation

[0017] 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.

[0018] Please see Figure 1-2The sheet metal cabinet welding platform with clamping function in this embodiment includes a support platform 1, a support frame 2 is provided on the back of the support platform 1, an industrial camera 3 is fixed on the top wall of the inner cavity of the support frame 2, the support platform 1 is also provided with a clamping component 4 and a control box 7, and the control box 7 has a built-in dynamic thermal deformation compensation model.

[0019] In this embodiment, the support platform 1 includes a fixed platform, the lower surface of which is symmetrically provided with support feet, and the upper surface of which is provided with an installation groove, and an electromagnet 6 is fixed inside the installation groove.

[0020] It should be noted that, to avoid damage to the cabinet due to excessive clamping, it is compatible with products of different specifications and has strong versatility. The limit telescopic rod 5 provides stable guidance and improves clamping stability. The core innovative dynamic thermal deformation compensation model, combined with image data collected by the industrial camera 3, can calculate thermal expansion displacement in real time, actively adjust the driving component to offset the offset, break through the bottleneck of thermal deformation in high-temperature welding, ensure the precise position of the weld, and significantly improve the welding quality.

[0021] Please see Figures 3 to 5 In order to achieve all-round stable clamping, precise pressure control, active thermal deformation compensation, unobstructed corner welding, and automated intelligent control, the clamping assembly 4 in this embodiment includes a support plate 401 set on the support platform 1. A first driving member 402 is set on the outer side of the support plate 401. The outer side of the output shaft of the first driving member 402 slides through the support plate 401 and extends to the inner side. A first pressure sensor 403 is fixed on the outer side of the output shaft of the first driving member 402. A clamping frame 404 is fixed on the inner side of the first pressure sensor 403. A pressing member is provided on the clamping frame 404. A buffer layer 405 is provided in the inner cavity of the clamping frame 404. The four first driving members 402 can be driven synchronously or separately through the control box 7.

[0022] In this embodiment, there are four of each of the following components: support plate 401, first driving component 402, first pressure sensor 403, clamping frame 404, pressing component, and buffer layer 405, all of which are arranged in a rectangular shape on the support platform 1.

[0023] In this embodiment, the dynamic thermal deformation compensation model is integrated inside the control box 7, forming a closed-loop control structure with the industrial camera 3, the first drive component 402, the second drive component 406, and the pressure sensor. It is electrically connected to the industrial camera 3 to receive in real-time images of the weld pool, the edge contour of the sheet metal cabinet, and the temperature-related images of the welding area acquired by the industrial camera 3. Simultaneously, it receives pressure data from the first pressure sensor 403 and the second pressure sensor 407, enabling synchronous acquisition and transmission of multi-source data. A built-in database of the thermal expansion coefficient of sheet metal materials adapts to the material parameters of sheet metal cabinets of different specifications. Based on the acquired image data, it identifies the location of the weld pool and the cabinet... The edge displacement changes, combined with the preset thermal expansion coefficient, are used to calculate in real time the amount, direction, and rate of thermal expansion displacement of the sheet metal cabinet caused by the high temperature of welding. This is linked with the thermal deformation calculation module. Based on the calculated displacement data and the clamping and pressing pressure parameters fed back by the pressure sensor, targeted control commands are generated. The output force adjustment amount, displacement fine-tuning amount, and action sequence of the four first drive components 402 and the four second drive components 406 are specified. The control commands are transmitted to each drive component through electrical connection with the drive components. At the same time, the execution feedback data of the drive components is received in real time to judge the control effect. If the displacement deviation is not eliminated, the control commands are continuously optimized to form a closed-loop control.

[0024] In this embodiment, after the welding operation starts, the industrial camera 3 continuously acquires image data of the weld pool and the edge of the sheet metal cabinet every 0.1-0.2 seconds, and transmits it synchronously to the model's data acquisition module. Simultaneously, the pressure sensor provides real-time feedback on clamping and pressing pressure data to ensure pressure stability during control and prevent cabinet deformation caused by pressure changes. After receiving the image data, the thermal deformation calculation module extracts temperature-related features of the welding area, such as the size of the weld pool and edge contour offset, using an image recognition algorithm. Combined with the built-in thermal expansion coefficient of the sheet metal material, it accurately calculates the thermal expansion displacement of the sheet metal cabinet under high temperature, including horizontal and vertical displacement and deformation trends. The control command generation module then generates the control command based on the calculated data. The displacement data, combined with the current clamping and pressing pressure parameters, determines the driving component that needs adjustment and the adjustment range. If the cabinet shifts to one side due to thermal expansion, the first driving component 402 on the corresponding side fine-tunes the clamping displacement, and the second driving component 406 fine-tunes the pressing displacement, actively offsetting the shift caused by thermal deformation, ensuring that the weld position is consistent with the theoretical design position. The execution feedback module receives the execution data of the driving component in real time and simultaneously collects the adjusted image data through the industrial camera 3 to determine whether the displacement deviation has been eliminated. If the deviation does not reach the preset accuracy ≤0.02mm, the displacement amount is recalculated and the control command is optimized until the weld position remains stable, realizing dynamic thermal deformation compensation throughout the welding process, which is different from the passive correction mode of the existing technology.

[0025] In this embodiment, the pressing member includes a second driving member 406 fixed on the upper surface of the clamping frame 404. The outer side of the output shaft of the second driving member 406 slides through the clamping frame 404 and extends into it. A second pressure sensor 407 is fixed on the outer side of the output shaft of the second driving member 406. A pressing plate 408 is fixed on the lower surface of the second pressure sensor 407.

[0026] In this embodiment, the support foot is U-shaped, and the upper surface of the electromagnet 6 is flush with the upper surface of the fixed platform.

[0027] In this embodiment, the control box 7 controls the operation of four first driving components 402. Each first driving component 402 is a cylinder, and its output shaft pushes the first pressure sensor 403 and the clamping frame 404 to move towards the sheet metal cabinet. The four L-shaped clamping frames 404 move synchronously towards each other, performing a circumferential clamping of the sidewalls of the sheet metal cabinet. During this process, the first pressure sensor 403 monitors the clamping pressure data in real time. When the pressure reaches a preset threshold, it is fed back to the control box 7, which immediately controls the first driving components 402 to stop moving, ensuring uniform clamping force and avoiding excessive clamping. The clamping mechanism holds the damaged sheet metal cabinet. Simultaneously, the limiting telescopic rod 5 moves and extends synchronously with the clamping frame 404, providing stable guidance for the clamping frame 404 and preventing tilting during clamping. After clamping is completed, the control box 7 controls the four second driving components 406 to move. The second driving component 406 is a cylinder, and its output shaft pushes the second pressure sensor 407 and the lower pressure plate 408 to move downward, pressing down and fixing the top of the sheet metal cabinet. The second pressure sensor 407 monitors the downward pressure in real time to ensure that the downward pressure is stable, and together with the side wall clamping, it achieves all-round stable fixing.

[0028] In this embodiment, the electromagnet 6 is located at the center of the fixed platform. The industrial camera 3, the electromagnet 6, the four first driving components 402, the four second driving components 406, the four first pressure sensors 403, and the four second pressure sensors 407 are all electrically connected to the control box 7 through wires. The clamping frame 404 is L-shaped. The four support plates 401 are all provided with limit telescopic rods 5 inside. The opposite side of the four limit telescopic rods 5 is fixedly connected to the opposite side of the four clamping frames 404. The limit telescopic rod 5 includes a first sliding rod, and a second sliding rod is slidably connected inside the first sliding rod. The first driving component 402 and the second driving component 406 are both cylinders. The buffer layer 405 is a rubber layer.

[0029] It should be noted that the industrial camera 3 continuously collects image data of the weld pool and the edge of the sheet metal cabinet during the welding process. The control box 7 has a built-in dynamic thermal deformation compensation model. This model can calculate the displacement of the sheet metal cabinet caused by thermal expansion in real time based on the collected image data, and dynamically adjust the output force or displacement of the four first drive components 402 and the second drive component 406 in real time to actively counteract the offset caused by thermal deformation. This ensures that the weld position is always kept in the theoretical design position in the high-temperature welding environment, rather than being passively corrected. When the sheet metal cabinet needs to be welded at the corner, the clamping component 4 releases the sheet metal cabinet, and the electromagnet 6 is energized by the control box 7 to magnetically fix the sheet metal cabinet, which is convenient for welding processing.

[0030] The working principle of the above embodiments is as follows: First, the sheet metal cabinet to be welded is placed on the support platform 1. The control box 7 controls the action of four first driving components 402. The first driving component 402 is a cylinder, and its output shaft pushes the first pressure sensor 403 and the clamping frame 404 to move towards the sheet metal cabinet. The four L-shaped clamping frames 404 move synchronously towards each other, clamping the side wall of the sheet metal cabinet. During the process, the first pressure sensor 403 monitors the clamping pressure data in real time. When the pressure reaches the preset threshold, it feeds back to the control box 7. The control box 7 immediately controls the first driving component 402 to stop moving to ensure uniform clamping force and avoid excessive clamping damage to the sheet metal cabinet. At the same time, the limit telescopic rod 5 moves synchronously with the clamping frame 404 to provide stable guidance for the clamping frame 404 and prevent skewing during clamping. After clamping is completed, the control box 7 controls the action of four second driving components 406. The second driving component 406 is a cylinder, and its output shaft pushes the second pressure sensor 407 and the downward pressure... Plate 408 moves downwards to press down and fix the top of the sheet metal cabinet. The second pressure sensor 407 monitors the pressing pressure in real time to ensure stable pressure. Combined with the side wall clamping, it achieves all-round stable fixation. The industrial camera 3 continuously collects image data of the weld pool and the edge of the sheet metal cabinet during the welding process. The control box 7 has a built-in dynamic thermal deformation compensation model. This model can calculate the displacement of the sheet metal cabinet caused by thermal expansion in real time based on the collected image data, and dynamically adjust the output force or displacement of the four first drive components 402 and the second drive component 406 to actively counteract the offset caused by thermal deformation. This ensures that the weld position is always kept in the theoretical design position in the high-temperature welding environment, rather than being passively corrected. When the sheet metal cabinet needs to be welded at the corner, the clamping component 4 releases the sheet metal cabinet. The control box 7 controls the electromagnet 6 to be energized to magnetically fix the sheet metal cabinet, which is convenient for welding.
