[0029] Further, the longitudinal adjustment mechanism includes a first screw rod 10, a first threaded sleeve 11 and a first support seat 12, the first support seat 12 has a first adjustment groove 13, the first screw rod 10 is rotatably connected to the first support seat 12 and is located in the first adjustment groove 13, and the first screw rod 10 is driven by a first motor 14, the first threaded sleeve 11 is slidably connected to the first support seat 12 and is located in the first adjustment groove 13, the first threaded sleeve 11 is also threadedly connected to the first screw rod 10 and is sleeved on the first screw rod 10, and the lateral adjustment mechanism is arranged below the first threaded sleeve 11, the first support seat 12 is fixedly connected to the L-shaped plate 2 and is located on the L-shaped plate 2.

[0030] In this embodiment, by starting the first motor 14, the first motor 14 drives the first screw 10, and the first threaded sleeve 11 moves longitudinally in the first adjustment groove 13, thereby driving the lateral adjustment mechanism, the laser emitter 4 and the focusing lens 5 to move longitudinally, and then the steel wire is removed from different positions under the action of the lateral adjustment mechanism.

[0033] The present invention also provides a method for removing steel wires by laser, which is applied to the above-mentioned device for removing steel wires by laser, and comprises the following steps:

[0034] S1: Place the mesh to be processed on workbench 1, ensuring that the steel wire is partially exposed;

[0035] S2: using a laser transmitter 4 to generate a laser beam with high energy density, and focusing the laser beam on the surface of the steel wire through a focusing lens 5;

[0036] S3: Control the longitudinal adjustment mechanism and the transverse adjustment mechanism to move the laser beam on the steel wire along a predetermined path, so that the steel wire is heated rapidly and vaporized;

[0037] S4: Start the suction device 9 to suck the debris generated by vaporization into the grid 7 through negative pressure adsorption, and collect it into the suction device 9 through the conical bucket 8;

[0038] S5: Follow the above operation until all the steel wires to be removed are completely removed.

[0039] Furthermore, in step S1, before removing the steel wire, the mesh needs to be pre-treated by cleaning and drying.

[0040] In this embodiment, by pre-treating the mesh cloth by washing and drying before removing the steel wire, stains and moisture on the surface of the mesh cloth can be removed, thereby improving the removal quality.

[0041] Furthermore, in step S2: the wavelength, power and pulse frequency of the laser beam of the laser emitter 4 are adjusted according to the material, diameter and removal requirements of the steel wire.

[0045] Furthermore, the method of removing steel wires by laser is applicable to removing steel wires on meshes of different materials, specifications and structures.

[0046] In the present invention, the pretreated mesh is laid flat on the grid 7 on the workbench 1 to ensure that the steel wire part is completely exposed; as needed, a clamp or a pressure plate is used to fix the mesh to prevent it from moving; according to the material, diameter and removal requirements of the steel wire, the laser beam wavelength, power and pulse frequency of the laser emitter 4 are adjusted; it is ensured that the focusing position of the laser beam is accurate and the focal length of the focusing lens 5 is moderate; the laser emitter 4 is started to generate a high-energy-density laser beam; and then the longitudinal adjustment mechanism and the lateral adjustment mechanism are controlled to move the laser beam on the steel wire according to a predetermined path, and the laser beam is focused on the surface of the steel wire, so that it is heated rapidly and vaporized, and this process is repeated until all the steel wires to be removed are completely removed; while the laser is removing the steel wire, the suction device 9 is started, and the debris generated by vaporization is sucked into the grid 7 through negative pressure adsorption, and collected into the suction device 9 through the conical bucket 8.

[0047] In the present invention, this design allows the untreated position of the mesh to retain its original strength, and the removal of the steel wire position in conjunction with the low line width can have better ink permeability; and the precise removal of the steel wire will not cause damage to other positions. When produced in this way, there can be no steel wire blocking the ink channel within the required effective area, achieving better ink permeability while not losing the strength characteristics of the original mesh, thereby reducing printing costs for the photovoltaic industry and saving resources.
