Introduction
As laser technology continues to evolve, its application in various industries has expanded significantly. In the automotive sector, the flexibility and automation capabilities of laser technology have become indispensable in various manufacturing processes.
High-Power Laser Applications in Auto Parts Manufacturing
Laser engraving finds extensive applications in the automotive industry, ranging from deep engraving on components such as chassis numbers, engine cylinder bodies, to conventional marking tasks like QR code tracing and nameplate character marking.
Example 1
Utilizing a QCW150W laser with an F254 lens, 19 characters were engraved with a character height of 10mm and a depth of 0.3mm on a steel plate. The entire engraving process took less than 40 seconds. This application is ideal for components requiring high-power laser engraving, such as chassis and engine parts.
Example 2
For components like windshield wipers and steering joints, QR codes are precisely marked using a 50W laser with an F254 lens. A vision system assists in accurate positioning, ensuring a marking accuracy of ±0.05mm and a repetition accuracy of ±0.003mm. The engraving range is 660*510mm, and the engraving line speed is ≤7000mm/s.
Integrated Laser Marking in Automotive Assembly
In addition to individual component marking, laser technology plays a crucial role in the assembly of complete vehicles. Integrated into assembly lines, laser marking machine facilitates seamless marking on specific vehicle parts during production.
Example
In a passenger car assembly line, laser marking is applied to the right side of the vehicle’s cabin beam. As the vehicle frame moves along the production line, the assembly line halts momentarily, and a robotic arm equipped with a laser marking head precisely positions itself for engraving. After completion, the laser marking head retracts, and the assembly line resumes operation. This process ensures continuous and efficient marking without disrupting the overall production flow.
Advanced Features and Equipment
To enhance the efficiency of laser engraving machine, various features and equipment are incorporated. These include independent control cabinets, KBK tracks, robotic arms, air-knife dust removal systems, and smoke purification systems. These elements contribute to maintaining a clean and efficient working environment, ensuring the accuracy and longevity of the laser equipment.
Conclusion
The application of laser marking in the automotive industry demonstrates its versatility and efficiency in both component manufacturing and vehicle assembly. With ongoing technological advancements, laser technology continues to be at the forefront of innovations, contributing to the precision and automation essential for modern automotive production.
