Bonding Apparatus Alignment Correction via Operation Data

The system performs preliminary actions by recording operation data (number of continuous operations and idle time) during the bonding process, and pre-calculates movement distance corrections using linear regression equations. This preparation work is done in advance so that when bonding occurs, the corrected position can be applied directly without time-consuming vision unit intervention, thus resolving the contradiction between precision and speed.

The system implements feedback by using post-bonding inspection results to continuously update and correct the linear regression equation parameters. The inspection data feeds back into the system to refine the movement distance calculations, improving precision over time without requiring vision unit correction during each bonding operation, thereby maintaining high productivity.

The system changes the parameter used for positioning from simple count-based movement to a corrected movement distance that accounts for thermal expansion effects. By using linear regression equations that incorporate operation data (continuous operations count and idle time), the system calculates compensated movement distances that adjust for thermal drift, maintaining both speed and precision.

The system replaces the traditional mechanical positioning system (which relies solely on motor steps and physical encoders) with a computational correction system. The linear regression-based calculation substitutes for physical measurement and correction mechanisms, using mathematical models to predict and compensate for thermal expansion effects, thereby maintaining accuracy without mechanical complexity.
