Laser welding robots machine are increasingly favored by small and medium-sized enterprises due to their high efficiency, quality, and ease of management. For some products that require high precision, relying solely on welding robots cannot solve the problem, and users need to add laser seam tracking systems in a timely manner.
Why laser welding robots machine need to be equipped with a seam tracking system?
1.Actual production situation of users: There are many types of welding products with small batches, and high requirements for welding accuracy and welding technicians.
2.The cost of improving workpiece feeding is relatively high: updating the processing equipment of the original process, designing and purchasing high-precision tooling.
3.Laser welding robots machine often encounter various technical situations such as workpiece clamping deviation and sheet metal thermal deformation during the welding production process.
4.It often require manual repair welding after welding, which not only increases labor costs for small and medium-sized enterprises, but also improves the repair rate of products.
In order to improve the processing efficiency of laser welding robots machine, reduce teaching time and difficulty, it is necessary to add a laser seam tracking system in a timely manner.
The laser seam tracking system of the laser welding robots machine checks the suitability of the seam through the seam positioning function before welding, and accurately reaches the joint to be welded. Real time tracking of welds and monitoring of product deformation during the welding process. By installing sensors before collecting welding position data, collecting them through power or welding parameters, and then propagating them to the welding robot and various adaptive fuzzy control algorithms for the correct welding robot trajectory or special machine, adaptive control is achieved to achieve real-time seam tracking.
How to implement automated seam tracking and positioning?
The commonly used method for achieving seam tracking and positioning of laser welding robots machine is peripheral auxiliary detection, which mainly achieves laser tracking and photographic imaging tracking. This weld seam tracking and positioning control system can collect weld seam related data through optical measurement equipment, and the welding robot can adjust the motion trajectory of the adaptive arm through data comparison, thereby achieving real-time tracking of the weld seam.
