[0046] Figure 2 A three-dimensional diagram of a welding device provided in one embodiment of the present application. Figure 2 The welding equipment provided in the embodiment of the present application includes a welding worktable 1, a first rotating worktable 2, and a second rotating worktable 3.

[0047] The welding workbench 1 is used to provide energy required for welding. The energy source of welding can be laser, electric arc, or gas flame.

[0048] refer to Figure 2 The welding workbench 1 includes a moving component 11, a welding head component 12, and a wire feeder 13.

[0049] The motion assembly 11 is used to drive the welding head assembly 12 and the wire feeder 13 to move. The motion assembly 11 can be a single-axis motion assembly, a two-axis motion assembly, or a three-axis motion assembly. When the motion assembly 11 is a three-axis motion assembly, it can drive the welding head assembly 12 and the wire feeder 13 to move in three different directions (such as the X-axis direction, the Y-axis direction, and the Z-axis direction), which is convenient for adjusting the positions of the welding head assembly 12 and the wire feeder 13.

[0050] The welding head assembly 12 is used to provide energy required for welding.

[0051] The wire feeder 13 is used to feed the welding wire.

[0052] The welding head assembly 12 and the wire feeder 13 are arranged on the moving assembly 11, so that the moving assembly 11 can drive the welding head assembly 12 and the wire feeder 13 to move from one side of the welding workbench 1 to the other side of the welding workbench 1, for example: drive the welding head assembly 12 and the wire feeder 13 to move from the left side of the welding workbench 1 to the right side of the welding workbench 1, or drive the welding head assembly 12 and the wire feeder 13 to move from the right side of the welding workbench 1 to the left side of the welding workbench 1.

[0053] The first rotating worktable 2 is used to carry the electrode mesh and the electrode plate, and drive the electrode mesh and the electrode plate to rotate. The first rotating worktable 2 is located at one side of the welding worktable 1 (for example, the left side or the right side).

[0054] The second rotating worktable 3 is also used to carry the electrode mesh and the electrode plate, and drive the electrode mesh and the electrode plate to rotate. The second rotating worktable 3 is located at the other side of the welding worktable 1 (for example, the left side or the right side).

[0055] According to the above content, the electrode mesh 100 and the electrode plate 200 are carried on the first rotating worktable 2, and the moving component 11 drives the welding head component 12 and the wire feeder 13 to move to the welding position 101 of the electrode mesh 100 and the electrode plate 200, and the welding head component 12 emits laser to weld the welding position 101, and the wire feeder 13 sends the welding wire to the weld 101; after the electrode mesh 100 and the electrode plate 200 on the first rotating worktable 2 are welded, the moving component 11 drives the welding head component 12 and the wire feeder 13 to move from one side of the welding worktable 1 to the other side of the welding worktable 1, and welds the electrode mesh and the electrode plate located on the second rotating worktable 3. During this period, the first rotating worktable 2 is loaded to realize rotary double-station welding. When one side of the station is welding, the other side of the station is loaded, which can realize continuous welding and improve efficiency.

[0056] The electrode plate can specifically be a positive electrode plate, a negative electrode plate or a bipolar plate. When the electrode plate is a bipolar plate, the material of the bipolar plate is Q235A with nickel plating on the surface. During the processing, laser welding will damage the surface nickel plating layer of the bipolar plate. During subsequent use, the welding position between the bipolar plate and the electrode mesh will rust. The welding equipment provided in the embodiment of the present application emits a laser to weld the welding part through the welding head assembly 12. On the basis of laser welding, the welding wire (such as nickel welding wire) is fed through the wire feeder 13 so that the welding wire is filled into the weld, which can not only increase the strength of the welding, but also prevent the weld from rusting.
