Application of visual inspection in laser processing industry

Industry insiders probably know that the current laser marking, cutting, welding, micro-machining, etc. are all machine vision technologies. Machine vision can automatically locate the laser, automatically align, and then proceed to the next step, making the machine smarter.

Introducing machine vision into the laser processing industry, using industrial cameras to detect processing objects instead of human eyes, high resolution. The frame rate can be selected according to processing needs to improve artificial visual defects; machine vision technology can also accurately locate processing parts, which not only saves expensive fixture costs, improves processing accuracy, ensures quality, but also can continue to operate accurately and accelerate work efficiency.

Machine vision technology is widely used in high-precision processing fields such as laser cutting, laser welding, laser marking, and laser micro-machining.

Application of visual inspection in laser processing industry

1. Laser cutting

Laser cutting uses machine vision. Guided laser cutting can make the tangent of the product accurate and smooth, and can easily cut any required shape and size. From the automotive industry. Semiconductor industry. Mold industry to raw material industry. Consumer manufacturing industry. Aerospace industry will adopt laser cutting. Specific applications include wafer cutting, FPC flexible circuit board cutting, cloth label/leather cutting, automotive parts cutting, etc.

2. Laser welding

Laser welding has the advantages of no welding pollution and no deformation, and occupies an important position in precision instrument welding. Machine vision guidance is the icing on the cake. Specific applications include body steel plate welding, battery welding, pacemakers, sealed relays, etc.

3. Laser marking

Laser marking is widely used in various materials and almost all industries. Machine vision-guided positioning is aimed at fragile materials. The target size is small and the positioning accuracy requirement is high. In order to effectively improve production efficiency and ensure consistent product quality, large-scale marking operations are continuously carried out. Specific applications include IC marking, electronic consumer product marking, auto parts marking, shoe upper marking, etc.

4. Laser micromachining

Laser micromachining includes fine processing methods such as cutting and resistance adjustment, and the human eye has a large judgment error. Machine vision can clearly locate the processing area and guide the laser to work with the lowest error. Specific applications include laser resistor adjustment. Thin-film solar cell marking, etc.

The introduction of machine vision technology in the laser processing industry has effectively improved the accuracy of laser processing equipment. Intelligent and automated performance meets the needs of a large number of modern industries. Large-scale production quality requirements, reduce the production of defective products, save costs, and promote rapid development of enterprises.

Use visual inspection image sensors to replace human research, accurately detect defects on the surface of objects, optimize production process control through statistical analysis and classification of identified defect information, classify qualified and unqualified products, and improve customer trust and satisfaction.
