[0027] Specifically, the T-shaped frame 1 serves as the main support structure to carry the internal components. The drive assembly 2 drives the threaded rod 202 to rotate through the motor 201, which drives the sliding seat 204 to move linearly along the limiting rod 203, providing an accurate movement path for the laser head 4. The sliding seat 204 is threadedly connected and slidingly matched with the limiting rod 203 to ensure movement stability. One of the sliding seats 204 directly fixes the laser head 4 to perform cutting actions, and the other sliding seat 204 provides an installation reference for the protection component 3 through the two side support plates 301. The support plate 301 serves as the fixed base of the protection component 3, ensuring that the electric push rod and other components maintain a synchronous movement relationship with the laser head 4. The caster 6 realizes overall position adjustment of the device through rolling friction, adapting to different station requirements.
[0028] The protection component 3 includes two support plates 301, which are fixedly connected to the outside of the drive assembly 2. The upper surface of the support plate 301 is fixedly connected with two electric push rods 302. The output end of the electric push rod 302 is fixedly connected with a containing bin 303.

[0029] The isolation plate 305 is located directly above the adjacent sliding seat 204.
[0030] The inside of the isolation plate 305 is filled with cooling liquid.

[0032] Specifically, the protection assembly 3 is rigidly connected with the driving assembly 2 through the support plate 301, and the support plate 301 provides a stable mounting plane for the electric push rod 302; the electric push rod 302 adjusts the vertical height of the containing bin 303 through telescopic movement, so that the partition plate 305 adapts to the processing requirements of materials of different thicknesses; the electric telescopic rod 304 is fixed inside the containing bin 303, and the electric telescopic rod 304 drives the partition plate 305 to slide along the inner wall of the containing bin 303 through axial telescopic movement, so as to realize dynamic adhesion to the surface of the flexible circuit board; the partition plate 305 is located directly above the sliding seat 204, and the partition plate 305 is pressed down to form a physical barrier during cutting, so as to block the laser scattering and suppress the dust splashing; the cooling liquid filled in the partition plate 305 forms a circulation loop with the cooling liquid in the storage bin 504 through the liquid pump 7 and the liquid supply pipe 8, so as to continuously absorb the heat generated by laser processing and reduce the risk of material thermal deformation; the partition plate 506 in the storage bin 504 separates the dust collection area and the cooling liquid storage area, so as to prevent pollutants from mixing into the cooling system and affecting the heat dissipation efficiency.
[0033] The dust absorption assembly 5 includes an absorption ring 501 fixedly connected to the outer surface of the laser head 4, a fan 502 fixedly connected to the outer surface of the sliding seat 204 connected with the laser head 4, an absorption pipe 503 in communication between the input end of the fan 502 and the outer surface of the absorption ring 501, a storage bin 504 fixedly connected inside the T-shaped frame 1, and a conveying pipe 505 in communication between the output end of the fan 502 and the outer surface of the storage bin 504.

[0035] Specifically, when the dust absorption assembly 5 is in operation, the absorption ring 501 surrounds the outer surface of the laser head 4 to capture the metal dust and organic smoke generated by laser cutting in real time; the fan 502 generates a negative pressure airflow through the absorption pipe 503 to transport the pollutants collected by the absorption ring 501 to the storage bin 504 through the conveying pipe 505; the dust settling area is separated from the storage area of the replacement drawer 507 by the partition plate 506 in the storage bin 504, so as to ensure that the large-particle pollutants directly fall into the replacement drawer 507 and prevent the outlet of the conveying pipe 505 from being blocked; the replacement drawer 507 is designed in a sliding connection manner, so that it can be quickly pulled out for cleaning when the dust is fully loaded, thereby avoiding the influence of maintenance on production efficiency; the communication port of the conveying pipe 505 and the storage bin 504 is located above the side of the replacement drawer 507, and the gravity settling principle is used to realize gas-solid separation, reduce the dependence on the filter screen, and reduce the system maintenance cost.
[0036] Working principle: in use, the device is transferred to the working area through the casters 6 at the bottom of the device; the flexible circuit board is placed on the sliding seat 204 below the isolation plate 506, and then the motor 201 drives the threaded rod 202 to rotate, thereby driving the sliding seat 204 connected with the threaded rod 202 to move transversely along the limiting rod 203, so that the laser head 4 is accurately positioned to the cutting starting point; then the containing bin 303 is lowered to a preset height by the electric push rod 302, and the electric telescopic rod 304 extends the isolation plate 305 to close to the surface of the flexible circuit board, thereby forming a local closed space to limit the laser scattering range; when the laser head 4 emits high-energy laser for cutting, the absorption ring 501 absorbs the dust and smoke generated by cutting in real time through the negative pressure generated by the fan 502 through the absorption pipe 503, and the pollutants are introduced into the replacement drawer 507 in the storage bin 504 for temporary storage through the conveying pipe 505; at the same time, the cooling liquid 7 in the storage bin 504 is circulated and delivered to the inside of the isolation plate 305 through the liquid supply pipe 9 by the liquid pump 8, so as to continuously absorb the heat generated by laser processing to reduce the range of the heat affected zone; when the cutting path needs to be turned, the driving assembly 2 adjusts the moving track of the sliding seat 204 through multiple motors 201, so as to ensure that the isolation plate 305 always covers the cutting area until the whole processing process is completed.
[0037] Finally, it should be noted that: the above only describes the preferred embodiments of the present application, and is not intended to limit the present application, although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for some technical features, any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
