Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of laser drilling, and particularly relates to a warp-knitted mesh fabric drilling process for automobile seats and a drilling machine thereof. BACKGROUND

[0002] Laser drilling is a method of using a laser beam to accurately drill holes on a warp-knitted mesh fabric. Compared with traditional mechanical drilling, laser drilling has higher precision and flexibility. Laser can cut holes of various shapes on the warp-knitted mesh fabric at a very high speed and precision, and even can make complex patterns. This allows designers to have more freedom in creation and achieve more creativity, and is widely used in clothing, home and industry and other fields.

[0003] The working principle of the laser drilling machine is to heat the surface of the warp-knitted mesh fabric to a melting or vaporizing temperature by a laser beam to achieve drilling. The advantage of laser drilling is not only its precision, but also its protection of the warp-knitted mesh fabric. Traditional mechanical drilling may cause wear and deformation of the edges of the warp-knitted mesh fabric, while laser drilling can effectively reduce this situation. Laser drilling can also achieve seamless cutting, avoiding the tearing problem of the warp-knitted mesh fabric that may occur in the traditional drilling process.

[0004] In order to realize continuous drilling of the warp-knitted mesh fabric, the existing technology has adopted the technology of unwinding the warp-knitted mesh fabric immediately after printing and simultaneously winding. This technology has a fast printing speed, but since there is tension between unwinding and winding, the existing laser drilling machine causes part of the fibers of the warp-knitted mesh fabric to be broken when continuously drilling in the above-mentioned manner, and the warp-knitted mesh fabric causes hole position deviation due to the broken part of the area, affecting the drilling precision.
