Abstract

An automatic processing device of strain gauge in the force sensor was designed to solve the low machining efficiency, poor accuracy, uniformity and consistency. Based on the principle of electropolishing, the corrosion process of strain gauge and the resistance measurement process were integrated to realize accurate and efficient machining of the strain gauge in the force sensor. Results show that the processing accuracy, consistency and efficiency of strain gauge in force sensor could be significantly improved by using this device. The dispersion degree of the processed strain gauge parameters of the force sensor had been reduced by about 40%, the consistency of the thickness distribution was significantly improved, and the average processing time was shortened by more than 60%, which effectively improved the quality of the strain gauge of the force sensor and the long-term stability.
