Robot Integration Technology for Laser Marking

2026-10-09 Technical Insights

Introduction

In automotive manufacturing, permanent identification marks such as the Vehicle Identification Number (VIN) must be applied to body-in-white structures with absolute consistency and durability. As production lines move toward higher automation, the method of applying these marks has shifted from manual or semi-automatic stations to fully integrated robotic cells. Robot integration technology for laser marking addresses the need to combine the reach and flexibility of industrial robots with the precision and depth control of laser marking systems. This article examines how robot-mounted laser marking works, what system features support reliable integration, and where this technology fits within automotive and industrial production environments.


Robot VIN Marking Status


Product Overview

The KINMARK Deep Laser Marking Machine is a marking and traceability solution designed for deep VIN marking on high-strength materials. It is built to apply permanent marks on high-strength steel plates with yield strength exceeding 700 MPa and hot-formed steel plates with strength up to 1500 MPa. On body-in-white, the marking depth can reach more than 0.2 mm.

The system is not limited to standalone operation. It is engineered with various mounting interfaces that allow quick integration with industrial robots or assisted manipulators, making it suitable for automated production lines. This integration capability is central to the product's role in modern automotive assembly and traceability workflows.

Working Principle

Robot integration technology for laser marking combines a laser marking head with a robotic positioning system. The robot positions the marking head relative to the workpiece, and the laser applies a deep mark according to the programmed pattern. The KINMARK system uses a special marking process that ensures clear rubbing results after painting, which is important for VIN readability throughout the vehicle's life.

The marking depth on body-in-white can reach more than 0.2 mm, providing a permanent mark that withstands subsequent painting and assembly processes. For applications requiring precise positioning, an optional 3D vision guidance system can be added. This system enables precise positioning and accurate marking, which improves production efficiency in automated cells.

For quality control, the system can be equipped with an optional 3D laser scanning measurement and OCR recognition system. This provides online inspection of marking quality and ensures 100% traceability. The combination of robot motion, laser marking, and optional vision or scanning modules forms a closed-loop process suitable for high-volume production.
