Technical Field

The utility model relates to the technical field of machinery, in particular to laser cutting system.

Background

Generally, the cutting method may include a drill cutting method and a water jet cutting method. The drill cutting method utilizes a rotary cutting drill to cut the substrate. However, the cutting causes the substrate to vibrate. Therefore, the drill cutting method can only be used for thicker substrates and/or less flexible substrates, so as to avoid the damage of the substrate or the deviation of the substrate position caused by the vibration during cutting. In addition, the precision of the substrate cut by the drill cutting method is low, and unnecessary burrs are generated at the edge of the substrate.

Furthermore, the water jet cutting method uses a rotary cutting blade and injects water to perform the cutting. However, water is required to be injected for cooling during cutting. After the cutting, subsequent operations such as baking are required, thereby increasing the production cost and the manufacturing time of the product.
