5. The sector-shaped panel splicing equipment according to any one of claims 2 to 4, characterized in that, The protective part is a long copper plate with cooling water pipes, and the long copper plate is made of brass.

6. The sector-shaped plate splicing equipment according to claim 5, characterized in that, The lifting mechanism includes a lifting cylinder, a guide column, and a second guide sleeve. The guide column is located on the lower side of the second operating platform, and the second guide sleeve is located on the second gantry frame. The movable ends of the plurality of lifting cylinders are evenly connected to the second operating platform through floating joints, and the fixed ends of the lifting cylinders are attached to the second gantry frame.

7. The sector-shaped plate splicing equipment according to claim 5, characterized in that, The exchange platform also includes a workstation platform, which spans across the first and second operating platforms.

8. The sector-shaped plate splicing equipment according to claim 5, characterized in that, The sector panel splicing equipment includes a control system, which is used to control the device, the exchange platform, and to retrieve different applications for sector panels of different specifications.

9. The sector-shaped plate splicing equipment according to claim 5, characterized in that, The first traveling frame includes a front traveling frame and a rear traveling frame, which are respectively mounted on a first ground track. The second traveling frame includes a front minor traveling frame and a rear minor traveling frame, which are respectively mounted on a second ground track.

10. A splicing method for sector-shaped panels, characterized in that, The process, performed using the sector-shaped panel splicing equipment according to any one of claims 1 to 9, includes the following steps: (1) The exchange platform is located at the loading position, and all moving components on the welding device are at a safe height; (2) The robot continuously picks up two sector plates and places them onto the first operating platform of the upper moving platform. Then the upper moving platform moves to the welding position and is located below the welding device. (3) The clamping mechanism descends, and at the same time the lower lifting and moving platform rises. The robot picks up the fan-shaped plate and places it onto the second operating platform of the lower lifting and moving platform. After the two plates are loaded, the robot descends. (4) The cylinder baffle assembly on a set of pressing frame in the pressing mechanism presses down, and multiple sets of push plate cylinders on the first operating platform drive the limit wheel to push the plate to the splicing surface to coincide with the stop finger on the cylinder baffle assembly. The cylinder clamping assembly clamps the plate material, and then the cylinder baffle assembly releases. (5) The cylinder clamping assembly and cylinder baffle assembly on another set of pressing frame in the pressing mechanism repeat the action described in step (4); (6) The arc-starting plate feeding mechanism moves to send out an arc-starting plate and presses it against the arc end face of the sector plate. The welding gun on the welding host moves while welding the two assembled sector plates. After welding is completed, the arc-starting plate feeding mechanism and the welding host return to their original positions. (7) The cylinder clamping assembly releases the plate material, and then the clamping mechanism rises back to its original position; (8) The lower lifting and moving platform moves from the loading position to the welding position, while the upper moving platform moves from the welding position to the loading position. (9) Replace the upper moving platform with the lower lifting moving platform and repeat steps (4) to (6). At the same time, the unloading robot unloads the plate material that has been spliced ​​and welded on the upper moving platform. (10) Repeat steps (1) to (9).
