Shim Bond Coverage Analysis Using Artificial Intelligence

Shim bond coverage analysis is a common practice in brake and pad manufacturing during brake pad development. This analysis is used to assess the quality of a shim bond and quantify it in case of any quality or de-bond issues during production and warranty returns. Currently, the analysis is carried out manually in the industry using a 1:1 template printed on tracing paper, which is placed on the deboned shim to identify bad bonded regions. The bond coverage is then calculated manually based on the data obtained from the template, which is a time-consuming process taking around 15 minutes per pad/shim analysis. To minimize manual work and increase accuracy, artificial intelligence is being used to estimate the shim bonding quality and coverage. The idea is to feed the deboned shim and pad picture to the model and predict the following: Whether the bond coverage is good or bad. Identify the good/bad and unnecessary regions on the shim/pad for bond coverage analysis.
