AI Technical Summary

Technical Problem

The pressure feet of existing drilling machines need to be replaced manually on a regular basis, which is time-consuming and poses operational risks. Furthermore, failure to replace them in a timely manner can affect the quality of the circuit board or even lead to its scrapping.

Method used

Design a pressure foot replacement assembly, including a main body and a receiving cavity. Automatic disassembly and installation of the pressure foot are achieved through structures such as flanged limit and guide rod. Elastic elements and check blocks are used to ensure that the pressure foot is in a preset position. A detection component is set to monitor the replacement process.

Benefits of technology

It improves the accuracy and efficiency of pressure foot replacement, reduces labor requirements, enhances automation, reduces pressure foot wear, lowers drilling machine failure rate, and improves circuit board processing efficiency and quality.
