AI Technical Summary

Technical Problem

Existing technology requires the sensor to be installed in the whole machine before pressure testing. This process is cumbersome and prone to measurement deviations due to interference from other components of the whole machine. If the calibration fails, the sensor needs to be disassembled and repaired, causing production line downtime and cost waste.

Method used

Design a precision calibration device for injection pressure sensors in an all-electric injection molding machine, including a base, a pressure application component, and an adapter plate. Through a stepped test groove and a detachable pressure plate, it can adapt to sensors of different sizes, ensure that the force direction is consistent with the overall machine installation state, eliminate installation errors, support the calibration of multiple diameter sensors with a single device, and improve detection efficiency.

Benefits of technology

This enables rapid batch sampling inspection of sensors before assembly, avoiding rework after the entire machine is installed, reducing downtime losses, improving testing efficiency, eliminating the impact of installation errors, and ensuring calibration accuracy.
