Abstract
The invention relates to the technical field of welding machine protection, specifically a protective device for interlocking welding machines, a design method, and a shield. The device includes: an inductive detection module to detect the relative position between the shield and a human head; a position detection module to detect the filter lens position relative to the shield; a determination module connected to both detection modules to check if all parameters are within a preset range, converting them into an unlocking signal if so; and a transmission module to send this signal to the welding machine, allowing operator control after unlocking. The invention enhances safety, reduces injury risks, and offers reliable protection, with advantages like high safety, automatic control, and effective interlocking.
