Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of battery laser marking equipment, in particular to a laser marking device and a button cell production line. BACKGROUND

[0002] With the rapid development of 3C manufacturing industry, the demand for product identification technology is increasing. Traditional printing, labeling and other methods gradually expose their limitations, such as easy wear, environmental pollution, low production efficiency and other problems. Under this background, laser marking technology as a new type of surface treatment technology with high precision, high efficiency and environmental protection is gradually favored by the industry. Especially in the field of button cell manufacturing, the application of laser marking technology is revolutionary. Compared with traditional screen printing, laser marking technology does not need to use ink and solvent, avoiding pollution to the environment; at the same time, because the focusing point of laser beam is small and the heat affected zone is narrow, it will not cause damage to the surface of the battery, ensuring the performance and life of the battery. In addition, the bar code marked by laser has high anti-counterfeiting performance, which helps to crack down on fake and inferior products and protect the rights and interests of consumers. Therefore, the application prospect of laser marking technology in 3C manufacturing industry is broad, which is expected to promote the sustainable development and progress of the industry.

[0003] Although laser marking technology has many advantages in 3C manufacturing industry, there are still some technical problems in the actual application process. First, in the process of laser marking, the material will be rapidly heated, evaporated or burned under the action of laser, thereby releasing some small particulate matter and gaseous substances. These substances not only may pollute the operating environment, but also may pose a threat to the health of the operating personnel. Secondly, the laser used in laser marking is a high-energy body beam, which is easy to focus on the tooling equipment outside the target position once it deviates, thereby causing equipment damage or affecting production safety.
