[0002] PCB is the abbreviation of Printed Circuit Board. It is a substrate used to support and connect electronic components, usually made of insulating material, with conductive tracks and pads on the surface. PCB is widely used in electronic devices such as computers, mobile phones, televisions, automotive electronic systems, etc. They provide a way of mechanical support and electrical connection so that electronic components can be reliably mounted and connected together to form a complete circuit.

[0003] A PCB drilling machine is a device specifically designed for drilling holes on a Printed Circuit Board (PCB). PCB drilling machines are usually highly accurate and efficient, and can accurately drill holes in PCB boards for mounting electronic components or making connections. These machines are usually equipped with drill bits and drilling mechanisms that can drill holes in PCB boards as needed, and are usually able to handle complex drilling requirements, such as holes of different sizes, holes in different locations, etc. PCB drilling machines play a vital role in the electronics manufacturing industry. They can improve production efficiency, ensure product quality, and are suitable for large-scale production environments.

[0004] PCB boards are usually made of hard materials (such as glass fiber reinforced epoxy resin), and drill bits are usually made of carbide or steel. During long-term use, the contact between the drill bit and the PCB material will cause wear on the drill bit surface, affecting the quality of PCB board drilling. Utility Model Content

[0021] Furthermore, a rotating motor is provided at the bottom of the second operating rod and the base, and the rotating motor rotates by 120° each time.

[0022] The beneficial effect of adopting the above-mentioned improvement scheme is that by providing a rotating motor, the base can be rotated during operation, thereby replacing a new drilling needle.

[0023] Compared with the prior art, the beneficial effects of a PCB drilling machine provided by the utility model are:

[0024] Enhanced operational flexibility: The base and drilling needle are controlled by the operating lever, which makes the operation more intuitive and more flexible.

The drilling needle and the base can be detachably connected, making maintenance and replacement easier and faster.

[0027] Improved precision and stability: The chamfered boss design provides a more stable support, which is conducive to improving the precision and stability of drilling. In addition, the design of the operating lever also helps to control the force and angle during the drilling process, further improving the accuracy of drilling.

[0028] In summary, this utility model design brings multiple benefits such as enhanced operational flexibility, improved work efficiency, easy maintenance and replacement, and improved precision and stability, which helps to improve the overall performance and work efficiency of the PCB drilling machine.
