Batch consistency is the core evaluation index of industrial automated production, especially for liquid cooling manifolds with strict assembly and sealing requirements. DKD Automation equips the manifold laser welding machine with high-precision CNC motion positioning system and intelligent visual compensation module, achieving ±0.01mm repeat positioning accuracy. The system can accurately lock the welding track of manifold ports, branch pipes and end caps, eliminating position deviation caused by manual clamping and operation errors. For multi-port complex manifolds with 4, 6, 8 or more branches, the equipment supports one-time clamping and full-process welding without secondary positioning and re-clamping, greatly improving production efficiency. The built-in visual detection system can automatically identify tiny dimensional deviations of workpieces, dynamically compensate the welding track in real time, and ensure that the welding position and weld size of each product in different batches remain consistent. This precise positioning capability completely solves the batch quality fluctuation problem of traditional manual welding, laying a solid foundation for standardized large-scale production of liquid cooling manifolds.
