[0002] The automotive body-in-white refers to the overall body structure of a car before it is painted and before components such as the engine, chassis, and interior are installed. It is typically constructed from metal materials such as steel or aluminum sheets, joined together through welding and riveting. The front and rear bulkheads of the automotive body-in-white are important load-bearing and connecting components in the body structure. The front bulkhead is located between the engine compartment and the passenger compartment, while the rear bulkhead is located in front of the trunk. Due to the complex structure and dense weld points of the front and rear bulkheads, an automated welding island is required.

[0003] The automatic welding island for the front and rear bulkheads of a car body-in-white is a highly efficient and automated welding unit used for welding the front and rear bulkheads of the car body-in-white. In traditional technology, the installation structure of the robotic arm is mostly fixed. When faced with significant differences in the size parameters, weld layout, and welding process of the front and rear bulkheads of different car models, replacing the robotic arm requires manual removal of screws. This process is time-consuming and labor-intensive, affecting the use of the welding island. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figures 1-3 An embodiment of this utility model provides an automatic welding island for the front and rear panels of an automobile body-in-white, including a workbench 1. A robotic arm 2 is installed inside the workbench 1, and a welding head 3 is installed on the outer wall of the robotic arm 2. A hydraulic rod 4 is fixedly connected to the inner wall of the workbench 1, and a transmission block 5 is fixedly connected to the output end of the hydraulic rod 4. A slide rail 6 is slidably connected inside the transmission block 5, and a U-shaped frame 7 is rotatably connected inside the transmission block 5. A slide seat 8 is rotatably connected to the outer wall of the U-shaped frame 7, and a slide rail 9 is slidably connected inside the slide seat 8. An L-shaped block 10 is fixedly connected to the upper surface of the slide seat 8, and the outer wall of the L-shaped block 10 is slidably connected inside the robotic arm 2. A clamping assembly is installed on the upper surface of the workbench 1.

[0025] Specifically, clamping components are provided on both sides of the workbench 1 to clamp and fix the panel, reducing manual operation. The welding head 3 of the robotic arm 2 facilitates flexible welding of the panel. The transmission block 5 is pushed or pulled by the hydraulic rod 4, which drives the slide block 8 and the slide rail 2 9 to move through the U-shaped frame 7. The slide rail 1 6 supports and limits the movement of the transmission block 5, and the slide rail 2 9 supports and limits the movement of the slide block 8. A groove is provided at the bottom of the robotic arm 2 to match the L-shaped block 10. The L-shaped block 10 slides in and out of the robotic arm 2 to limit or release the installation of the robotic arm 2.

[0026] Reference Figure 2 The clamping assembly includes an upper clamp 11 and a lower clamp 12. The lower surface of the upper clamp 11 is disposed on the upper surface of the worktable 1, and the lower surface of the lower clamp 12 is disposed on the upper surface of the worktable 1.

[0027] Specifically, the upper surface of the workbench 1 is provided with multiple upper clamps 11 and lower clamps 12, which are symmetrical from left to right. The upper clamps 11 and lower clamps 12 cooperate to clamp and fix the panel.

[0028] Reference Figure 3 The lower surface of slide rail 16 is fixedly connected to the inner bottom wall of worktable 1, the lower surface of slide rail 29 is fixedly connected to the inner bottom wall of worktable 1, and the outer wall of L-shaped block 10 is slidably connected to the inside of worktable 1.

[0029] Specifically, the inner bottom wall of the worktable 1 fixes slide rail 6 and slide rail 9, and the non-contact between slide rail 6 and slide rail 9 avoids motion interference. The movement of L-shaped block 10 is restricted by the interior of the worktable 1.

[0030] Reference Figure 4 A U-shaped rod 13 is slidably connected inside the worktable 1, and a slide rod 14 is fixedly connected to the bottom end of the U-shaped rod 13; the outer wall of the slide rod 14 is slidably connected to the inside of the worktable 1, and a trapezoidal block 16 is fixedly connected to the outer wall of the slide rod 14; the outer wall of the trapezoidal block 16 is slidably connected to the inside of the worktable 1, and a mounting block 17 is slidably connected to the rear outer wall of the trapezoidal block 16; the outer wall of the mounting block 17 is slidably connected to the inside of the worktable 1, and the upper surface of the mounting block 17 is fixedly connected to the lower surface of the upper clamp 11; a spring 15 is fixedly connected to the front outer wall of the trapezoidal block 16, and the outer wall of the spring 15 is fixedly connected to the inner wall of the worktable 1.

[0031] Specifically, the movement range of the U-shaped rod 13 is limited by the interior of the workbench 1. The slide rod 14 is moved by holding the U-shaped rod 13. The movement of the slide rod 14 and the trapezoidal block 16 is supported and offset by the interior of the workbench 1. Without external force driving the U-shaped rod 13, the spring 15 itself pushes the trapezoidal block 16 backward, thereby providing support for the trapezoidal block 16 inside the mounting block 17 and improving the stability of the upper clamp 11 installation.

[0032] Working principle: When using this welding island, the front and rear panels to be welded are placed on the lower clamps 12 on both sides of the workbench 1. The front and rear panels are clamped and fixed by the cooperation between the upper clamp 11 and the lower clamp 12. The welding head 3 is driven by the robotic arms 2 on both sides of the workbench 1 to weld the front and rear panels, thereby reducing manual intervention. The hydraulic rod 4 pushes the transmission block 5 to slide on the outer wall of the slide rail 1 6, which drives the U-shaped frame 7 to move to the right and rotate forward at the same time, thereby driving the slide block 8 to move forward on the outer wall of the slide rail 2 9. This causes the L-shaped blocks 10 on both sides of the workbench 1 to move towards the direction of the transmission block 5 and slide out of the interior of the robotic arm 2 without being limited, making it convenient to remove the robotic arm 2 for cleaning or maintenance.

[0033] By pulling the U-shaped rod 13, the sliding rod 14 slides forward inside the worktable 1, causing the trapezoidal block 16 to move forward and compress the spring 15. The trapezoidal block 16 slides out of the interior of the mounting block 17, no longer limiting the mounting block 17, making it easy to slide the mounting block 17 out of the interior of the worktable 1, thereby disassembling the upper clamp 11. At the same time, multiple upper clamps 11 and lower clamps 12 are provided on the surface of the worktable 1, and the upper clamps 11 and lower clamps 12 are all connected with the same buckle structure, which facilitates the adjustment of the upper clamps 11 and lower clamps 12. During use, this welding island not only facilitates the maintenance or replacement of the robotic arm 2, but also enables the upper clamps 11 and lower clamps 12 to be disassembled, making it easy to replace them according to actual production needs.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
