Description

Technical Field

[0001] The invention relates to the technical field of ultraviolet picosecond cutting equipment, in particular to ultraviolet picosecond PCB circuit board cutting equipment. Background Art

[0002] UV picosecond laser technology is an advanced laser processing technology that combines the advantages of UV laser and picosecond pulse width, and has the characteristics of high precision, low thermal impact, and high efficiency. UV picosecond laser refers to laser technology with a laser pulse width of picoseconds (i.e. 10^-12 seconds) and a wavelength in the ultraviolet spectrum. It is suitable for processing a variety of materials, including metals, non-metals, transparent materials, etc., especially for processing heat-sensitive materials such as glass and plastics. It has broad application prospects in precision manufacturing, scientific research, industrial processing and other fields. With the continuous development and improvement of technology, UV picosecond laser technology will play an important role in more fields.

[0003] PCB, the full name of which is Printed Circuit Board, is a substrate used to support and connect electronic components. It is made of insulating materials and conductive materials, and has many characteristics and a wide range of applications. The production process of PCB can be roughly divided into several steps, including cutting, pre-treatment, lamination, exposure, development, etching, film removal, internal inspection, lamination, drilling, electroplating, text printing, surface treatment, molding, testing and packaging. Each step requires fine processing to ensure the quality and performance of the final product.

[0004] The prior art discloses some invention patents in the field of ultraviolet picosecond cutting equipment technology. Among them, the invention patent with application number CN202310523406.7 discloses an ultraviolet picosecond laser cutting processing machine with visual inspection. By setting up a ring production line, the cutting of raw materials is realized. The half-gear ring gear meshing and gear meshing are adopted to ensure that when the circular plate rotates, it does not interfere with the light-isolating plate. When the power motor rotates one circle, the circular plate stops rotating, and the light-isolating plate contacts the bottom of the sink. Laser cutting and section detection are carried out simultaneously to improve work efficiency. The light-isolating plate blocks the light generated by the cutting process, reduces the impact of the cutting light on the industrial camera, and collects more realistic section photos to reflect the cutting quality.

[0005] UV picosecond PCB circuit board cutting equipment is a device that uses UV picosecond laser technology to perform high-precision and high-efficiency PCB circuit board cutting.
