[0054] The laser emitter 3 and the pin shafts connected to the two short connecting rods 12 in the lower profile linkage structure 1 are connected by a connecting piece.

[0055] Further comprising:

[0056] Two linear modules 5 arranged one above the other and vertically, the movable part of the upper linear module 5 and the main body of the lower linear module 5 are connected by a bolt, and the movable part of the lower linear module 5 and one of the two long connecting rods 11 in the upper profile linkage structure 1 away from the mounting seat 4 are connected by a rotary connecting piece 6;

[0057] Two linear modules 5 and photoelectric modules 22 are connected by a cable.

[0058] One of the two long connecting rods 11 in the lower profiling linkage structure 1 away from the mounting base 4 is provided with a sliding rail 7, and the connecting block 21 and the sliding rail 7 are slidingly connected.

[0066] Specifically, first, the relevant staff fixes the mounting base 4 on a stable workbench, and places the porous aluminum current collector to be processed at the designated position of the workbench, ensuring that it is directly below the laser emitter 3, and at the same time, a pre-designed laser sintering path layout is placed directly below the photoelectric module 22;

[0067] Then, the relevant staff generates an accurate running track that the photoelectric module 22 needs to follow through computer-aided design software or other graphic processing software, and this track should be based on the required laser sintering pattern and take into account the final reduced scale;

[0072] In this process, the laser emitter 3 emits a focused high-energy laser beam, which irradiates a specific area on the surface of the porous aluminum current collector, so that the material is locally heated until melting or vaporization, and then rapidly cools and solidifies to form the required shape.
