[0027] 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.

[0028] Please see Figure 1-7 This utility model provides a technical solution:

[0029] The high-end welding robot workstation for medium and heavy plates and profiles includes: Station 1, which has an overall fence structure, and a central control cabinet 2 is set on one side of Station 1. This fence structure design not only ensures the safety of operators, but also makes the internal environment of the workstation relatively independent, reducing the impact of external interference on the welding process. The central control cabinet 2 serves as the control center of the entire workstation, integrating functions such as the operation interface, control circuit and power management, making it convenient for operators to centrally control and monitor the workstation.

[0030] The three-axis gantry truss 3 is installed inside the station 1. The movable end of the three-axis gantry truss 3 is connected to the inverted mounting platform 4. Through its stable column structure and flexible electric guide rail system, the three-axis gantry truss 3 realizes large-span, high-precision three-dimensional spatial movement, providing the welding robot 5 with a wide working range and precise positioning capability. The design of the inverted mounting platform 4 enables the welding robot 5 to perform welding operations at the optimal angle and position, further improving welding quality and efficiency.

[0031] The welding robot 5 is set at the bottom of the inverted mounting platform 4. As the core execution component of the workstation, the welding robot 5's high precision and high speed make the welding process more automated and intelligent. With the fixation of the inverted mounting platform 4, the welding robot 5 can stably perform welding tasks, while reducing the impact of vibration or displacement on the welding quality.

[0032] The positioner 6 is installed inside the station 1. The positioner 6 includes a mounting base 601, which is fixedly installed inside the station 1. A workpiece locking cylinder 602 is installed on the mounting base 601. The positioner 6 is stably installed inside the station 1 through its mounting base 601, providing stable support and flipping function for the welded workpiece. The workpiece locking cylinder 602 ensures the stability and safety of the workpiece during the welding process and prevents welding quality problems caused by workpiece movement or flipping.

[0033] The three-axis gantry truss 3 includes several sets of columns 301, the bottom ends of which are fixedly installed inside the station 1. The tops of the columns 301 are fixedly connected to X-axis electric guide rails 302. The movable end of the X-axis electric guide rails 302 is connected to a movable plate 303. A Y-axis electric guide rail 304 is fixedly installed on the top of the movable plate 303. A movable plate 305 is connected to the movable end of the Y-axis electric guide rail 304. A Z-axis electric guide rail 306 is fixedly installed on the movable plate 305. The movable end of the Z-axis electric guide rail 306 is fixedly connected to the inverted mounting platform 4. A complex electric guide rail system, through precise control and drive, enables the three-axis gantry truss 3 to move flexibly and position precisely in three-dimensional space. The coordinated work between the electric guide rails of each axis allows the welding robot 5 to perform welding operations at the optimal path and speed, improving welding efficiency and quality. This fixed connection method ensures the stable movement and precise positioning of the inverted mounting platform 4 in the Z-axis direction, providing a stable operating platform for the welding robot 5. At the same time, it also reduces the impact of vibration or displacement on welding quality, improving the reliability and consistency of welding.

[0034] The welding robot 5 includes a six-axis robot 501, which is mounted on the bottom of the inverted mounting platform 4. The moving end of the six-axis robot 501 is fixedly connected to a welding torch 502. With its high flexibility and high precision, the six-axis robot 501 can execute complex welding trajectories and movements during the welding process. The welding torch 502, as the welding execution component, ensures high welding quality through its precise positioning and stable welding performance. Through the collaborative work of the six-axis robot 501 and the welding torch 502, the automation and intelligence of the welding process are realized.

[0035] It also includes a weld seam tracking sensor 503, which is installed on the moving end of the six-axis robot 501. The weld seam tracking sensor 503 can scan the weld seam position in real time and transmit the data to the robot and the welding controller. Through this function, the workstation can automatically adjust the welding trajectory and parameters during the welding process to ensure the consistency and stability of the welding quality. At the same time, it also reduces welding quality problems caused by workpiece errors or deformation.

[0036] The central control cabinet 2 is equipped with a reset button and a start button. A cable tray 7 is fixedly installed on one side wall of the central control cabinet 2. The reset button and start button facilitate the operator to quickly start and reset the workstation. The cable tray 7 is used to organize and fix the cables in the workstation, avoiding safety hazards and operational inconvenience caused by messy cables.

[0037] It also includes a gantry crane 8 for loading large components. The gantry crane 8 is a bridge-type gantry crane structure, including a track beam set above the station 1 and an electric hoist suspended on the track beam. The gantry crane 8 is equipped with a remote control handle. The lifting range of the gantry crane 8 covers the workpiece installation area of ​​the positioner 6. The design of the gantry crane 8 makes the loading and unloading process of large components more flexible and efficient. Through the remote control handle, the operator can remotely control the movement and lifting action of the gantry crane 8, which improves the convenience and safety of operation. At the same time, the lifting range of the gantry crane 8 covers the workpiece installation area of ​​the positioner 6, ensuring that large components can be accurately and quickly placed on the positioner 6 for welding operations.

[0038] Working Principle: The operator controls the electric hoist via the remote control handle of the gantry crane 8 to lift large workpieces onto the mounting base 601 of the positioner 6. The lifting accuracy of the gantry crane 8 ensures that the workpiece positioning hole is aligned with the workpiece locking cylinder 602. After the operator exits the fence of station 1, they press the start button on the central control cabinet 2. The workpiece locking cylinder 602 of the positioner 6 moves synchronously to clamp the workpiece. The system automatically performs initialization self-check to confirm that all equipment is in normal condition. The three-axis gantry truss 3 drives the welding robot 5 to move above the workpiece. The weld seam tracking sensor 503 emits a laser beam to scan the weld seam, obtain the three-dimensional coordinates of the weld seam, and transmit them to the robot control cabinet. The control cabinet automatically generates the welding trajectory according to the preset welding process parameters (such as current, voltage, and welding speed). The six-axis robot 501 drives the welding torch 502 to weld along the planned trajectory. At the same time, the positioner 6 adjusts the welding position according to the welding position. The system automatically flips the workpiece to ensure the weld is in the optimal welding position. During welding, the weld tracking sensor 503 monitors the weld offset in real time and feeds the data back to the control cabinet. This dynamically adjusts the robot's trajectory and welding parameters (such as wire feed speed and welding torch angle) to ensure welding accuracy. Once one side of the workpiece is welded, the three-axis gantry truss 3 moves the welding robot 5 to the other side of the workstation and repeats the above process to achieve continuous production at two workstations. After welding is completed, the positioner 6 is reset, and the operator removes the workpiece using the overhead crane 8 and then reloads the workpiece to be welded, entering the next production cycle. Throughout the process, the PLC system in the central control cabinet 2 coordinates the actions of the three-axis gantry truss 3, welding robot 5, positioner 6, and weld tracking sensor 503 via Ethernet to achieve multi-device linkage control, ensuring automation, high precision, and high stability in the welding process.
