The EV Circuit Breaker Assembling, Testing and Packaging Cell is a semi-automatic assembling and testing rotary table for an automotive safety component.

Safety always has priority. The circuit breaker is designed to detect any damage or bending in the battery pack, promptly sending a signal to switch off power, ensuring safety and preventing potential hazards.

The EV Circuit Breaker Assembling, Testing and Packaging Cell is equipped with six assembly and testing stations and one packaging station.

The operator must load the components onto the fixtures where the vision system developed by Osai, Osai Inspection System, verifies that they have been positioned correctly. This initial check is crucial to prevent errors in later stations.

Once the correct positioning is verified, the entire fixture is transferred inside the rotary table, a mechanism that allows several assembly operations to be performed in sequence. During each step, the vision system performs additional checks, ensuring that each assembly step is completed correctly and that the components are assembled according to the required specifications.

The most critical step in the entire line is the micrometric mechanical calibration of the switch. This operation requires extreme precision, with adjustments on the order of micrometers, to ensure that the switch functions perfectly. Such precision is essential in high-tech, and high-precision applications such as this.
An additional final check to ensure that the final testing stages meets the required standards is performed by the system.

At last, there is the Laser marking phase, where each component or assembled product is identified with a unique code for traceability and quality control, and the packaging on KLT boxes.

EV Circuit Breaker Assembling, Testing and Packaging Cell is designed to ensure full traceability, seamlessly integrating MES (Manufacturing Execution System) to monitor and recover every stage to the line in real time.
