Laser Seam Tracking Technology
Details about Minyue’s SmartEye laser seam tracking system
Minyue’s SmartEye is a modern laser seam tracking system that enhances robotic welding precision by allowing the robotic welder to travel along welding seams with exceptional accuracy. Welding seam detection with the SmartEye is achieved through advanced visual sensors and a laser line generator, ensuring sub-millimeter tracking accuracy even on complex, curved seams.
The SmartEye system works by projecting a red laser line onto the workpiece material. A high-speed camera captures an image of the laser line, and smart vision algorithms in the SmartEye process the image to determine the laser line’s position relative to the welding seam. This data is instantly relayed to the robot controller, which adjusts the robotic welding torch’s position and movement in real-time. The entire process occurs within milliseconds, enabling seamless tracking and precision, even during high-speed welding operations.
Key benefits of laser seam tracking for robotic welding
Laser seam tracking provides several important advantages over manual welding. It enables more precise tracking of complex, non-linear seams. This results in higher joint quality and reduced rework. The robotic welder can stay on seam consistently without drifting off course. Laser tracking also allows for higher welding speeds since the robot does not need to slow down at joints or corners. This significantly improves production efficiency. Additionally, laser tracking eliminates human error and variability from the welding process, leading to more uniform weld quality and mechanical properties.
Intelligent Welding Processes
Minyue’s welding expert system and intelligent decision functions
In addition to laser tracking, Minyue welding robots feature advanced process logic and an “expert system” to enable truly intelligent welding. The expert system contains a deep library of welding process knowledge accumulated from years of application experience. It understands how to optimize welding parameters based on joint geometry, material types, and other job specifications.
During the welding process, the robot’s sensors continuously monitor variables like current, voltage and torch position. The expert system integrates this real-time data with its process knowledge library. It then makes intelligent decisions to adjust welding parameters on the fly in order to ensure process stability and meet quality standards. For example, it can increase welding current temporarily at a joint to compensate for a change in joint geometry. Such closed-loop control results in welding of a consistently high quality without operator supervision or programming changes between parts.
Process libraries for flexible welding parameter configuration
Minyue robots come pre-configured with libraries of optimized welding parameter sets for common materials and joint types. Users can simply select the relevant material combination and joint profile for a new job from graphical user interfaces. The robot will then run the pre-defined process. These libraries simplify the initial setup and make the robots plug-and-play for typical applications.
At the same time, the libraries are fully customizable. Experienced users can tweak and improve parameters using the robot’s simulation and parameter adjustment functions. New parameter sets can also be added to the libraries. This gives factories the flexibility to configure the robots for specialized applications and customize processes as needed.
In summary, Minyue welding robots integrate advanced technologies like laser tracking, expert systems and process libraries to realize truly intelligent robotic welding. This results in higher productivity, repeatability and part quality compared to manual welding or older-generation robotic systems.

Minyue Offline Programming Software
Perfect combination with laser seam tracking
Minyue offers advanced offline programming software that works seamlessly with their robots. The software allows configuring the entire welding process virtually using CAD models of the workpiece. Programmers can digitally define welds, joint locations, torch paths and sequences. The programmed tasks are then simulated to verify access, collisions and cycle times before deployment on real robots.
A unique advantage is the software’s tight integration with Minyue’s laser seam tracking systems. Users simply need to import the 3D CAD model with its weld seams. The offline program then automatically generates optimized joint-following torch movements suitable for visual tracking. This eliminates manual lead-in/out programming and vastly simplifies the process compared to teaching individual path points. On the robot, the pre-programmed tasks run with perfect seam adherence using the built-in tracking functionality.

Smart Manufacturing and Non-Teach Robotics
Traditional robotic assembly cells rely on “teach pendant” programming where robots must be manually guided through tasks to record position points. This process requires dedicated programmers and limits flexibility when part designs change. As manufacturers strive for Industry 4.0 smart factories, more intuitive “non-teach” robotics solutions are gaining popularity.
Details about Minyue’s independent programming capabilities
Minyue industrial robots are able to operate independently without teach pendants using a combination of advanced technologies. Their integrated vision systems automatically extract part and tooling locations from CAD models uploaded in common file formats. Robots can then plan motions in simulation environments and auto-generate programs based on digital designs and assembly logic.
Subsequent process changes only require uploading revised CAD data – no reteaching. Integrated torque, force, and slip sensors allow for on-the-fly compensation without reprogramming. Robots monitor themselves for any unexpected contact forces during tasks and smoothly adjust speeds/directions. This level of “self-awareness” eliminates dependency on teach pendants while improving flexibility, safety, and productivity as part productions evolve over time.
Eliminating teach pendants for improved flexibility
Removing the teach pendant constraint resolves many issues faced in traditional robotic cells. Assembly lines can rapidly switch between model variants without halting production for reprogramming. Process adjustments for quality improvements are implemented through parameter uploads instead of physical teaching. Packaged apps also allow non-robotics experts to safely operate cells and make simple modifications through intuitive interfaces. This independent functionality combined with collaborative robot designs opens up new applications of robotics on factory floors.
