AI Technical Summary
In existing technologies, the communication and collaboration efficiency between robots and control systems and sensing devices is low, and there is a lack of integrated analysis capabilities for multi-dimensional data such as voltage, current, displacement, and strain. This makes it impossible to dynamically optimize welding processes based on real-time operating conditions, resulting in limitations on the level of intelligence and production flexibility of multi-robot collaborative welding. Furthermore, traditional junction boxes have insufficient mechanical connection reliability under high-frequency vibration conditions, which can easily lead to signal crosstalk and increased contact resistance.
The design adopts a junction box, including a rotating structure of upper and lower shells. It achieves rapid splicing and separation through pawl and gear components. Combined with mechanical interlocking of limit blocks and return springs, it ensures stable connection of the motherboard under high-frequency vibration conditions. It also monitors key parameters in the welding process through multiple sensors to accurately detect anomalies and adjust welding parameters and paths accordingly.
It enables multi-sensor synchronous monitoring, accurately captures anomalies in key parameters of the welding process, reduces defect rate, improves the process adaptability and intelligence level of multi-robot collaborative welding, reduces signal interference, supports quality traceability and process optimization, and helps welding production lines upgrade to digitalization and intelligence.
