Shanghai Threetone Automation Technology Co., Ltd.

3D‑Infrared Vision Bolt Tightening Error‑Prevention System

It solves the problems of wrong‑torque and missing‑torque at manual tightening stations. Operators must complete tasks following the predefined tightening sequence, achieving 100% quality control and guaranteeing product quality.

AI‑based Operator Behavior Analysis and Error‑Prevention System

It can monitor operator behaviors in real time, ensure operators follow SOPs, and trigger timely alarms upon abnormalities. It realizes in‑process error‑prevention on manufacturing lines and improves product quality.

Acoustic‑signature‑based AI Monitoring & Analysis System

It addresses AI‑based monitoring of special sounds during production, such as the plug‑in sound of PACK connectors, to ensure connectors are fully seated and prevent quality incidents.

leak testing machine

The leak testing machine performs sealing tests on workpiece cavities, welds, assembly joint surfaces and other positions, supporting direct‑pressure, differential‑pressure and flow‑type testing modes. The device automatically collects pressure data to quickly judge whether workpieces have leaks. All testing data and judgment results are traceably recorded. It can effectively identify tiny leak defects and reject defective parts, preventing subsequent quality failures caused by seal failure. Widely used for component factory inspection, it ensures the reliability of complete‑machine assembly.
