Description

Technical Field

[0001] The utility model relates to the technical field of circuit board cutting, in particular to a laser aluminum-based product cutting device. Background Art

[0002] Aluminum substrate is a metal-based copper-clad laminate with good heat dissipation function. Generally, a single-sided board consists of three layers, namely the circuit layer (copper foil), the insulation layer and the metal base layer. Aluminum-based printed circuit boards (aluminum-based products) are circuit boards that are made by laminating aluminum-based metal substrates with copper foils. Due to its excellent properties such as good thermal conductivity, electrical insulation, voltage resistance, dimensional stability, and mechanical processing, aluminum substrates are widely used in circuit design solutions to effectively handle heat diffusion, thereby effectively reducing product operating temperatures, improving product power density and reliability, and extending product life.

[0003] Laser cutting of aluminum-based products is a non-contact processing method. The laser emitted from the laser is focused into a high-power density laser beam through the optical path system. The laser beam is irradiated onto the surface of the aluminum-based product, causing the product material to reach the melting point or boiling point. The relative position of the laser beam and the aluminum-based product moves, and finally the material forms a slit, thereby achieving the purpose of cutting. Compared with traditional cutting methods, it has the advantages of high processing accuracy, fast speed, and low cost.

[0004] The existing laser cutting machines mostly use manual operations for positioning and clamping during the cutting process, and the feeding and discharging of materials are relatively troublesome. The processing equipment needs to be paused and waited, which affects the processing efficiency and is not conducive to improving economic benefits. In addition, smoke is generated during the cutting of aluminum-based products, which will not only adhere to the product and affect the product appearance and positioning accuracy, but will also be discharged in the factory, causing adverse effects on the health of operators.

[0005] Therefore, a laser aluminum-based product cutting device is proposed, which is beneficial to improving the processing efficiency of cutting aluminum-based products and can avoid smoke emissions in the factory and affect the health of operators. Utility Model Content
