Description

Technical Field

[0001] This utility model relates to the field of PCB processing technology, specifically a high-precision drilling machine for PCB fixing blocks. Background Technology

[0002] Drilling is a critical process in the manufacturing of printed circuit boards (PCBs). As electronic devices become increasingly miniaturized and performant, the precision requirements for hole placement on PCBs are constantly rising. Traditional PCB drilling machines often suffer from inaccurate positioning and inconvenient adjustments, resulting in low production efficiency and difficulty in meeting the demands of high-quality PCB production.

[0003] Existing PCB drilling solutions typically rely on a single fixed platform for operation. If a PCB needs to be changed or repositioned during drilling, the current processing must be interrupted. This not only reduces production efficiency but also increases operational complexity. Furthermore, traditional drilling machines often use manual or simple mechanical movement mechanisms for drill bit position adjustment, which have limited adjustment range and cannot adequately adapt to the drilling needs of PCBs of different specifications and sizes, thus affecting processing accuracy and flexibility. Therefore, this invention proposes a high-precision PCB drilling machine with a fixed block. Utility Model Content
