Description

Technical Field

[0001] This utility model relates to the field of PCB board manufacturing technology, and in particular to a chamfering tool, chamfering device, and machine tool for PCB board processing. Background Technology

[0002] Currently, after the PCB substrate is sized and cut, the right angles of the substrate must be chamfered before subsequent processes. This is because the edges of circuit boards are typically fragile and easily damaged by friction. Chamfering makes the edges smoother, reducing damage caused by friction and thus increasing the lifespan of the circuit board. Additionally, using 90° traces in circuit board design and manufacturing occupies more space. Chamfering (such as 45° chamfering) saves space and makes it easier to avoid loops that could cause electromagnetic interference. This is especially important for high-density circuit board design.

[0003] Furthermore, burrs may be generated on the edges of the PCB during the manufacturing process. Chamfering can remove these burrs, reducing the risk of foreign object debris (FOD). FOD can cause problems with certain components, affecting the performance and reliability of the circuit board.

[0004] Currently, chamfering of PCB boards is generally achieved using a CNC router. This involves mounting chamfering cutters on the router's drive and sequentially chamfering right angles at the same height on the PCB board. Only one right angle can be processed at a time, resulting in low efficiency. Furthermore, if two chamfering cutters are installed simultaneously, for some thinner PCB boards, the large diameter of the cutters makes simultaneous processing impossible. This method is only suitable for thinner PCB boards.

[0005] Therefore, this application proposes a technical solution to solve the above problems. Utility Model Content

One end of the first cutting edge 311 and one end of the second cutting edge 321 are fixedly connected. The first cutting edge 311 and the second cutting edge 321 are arranged at an included angle. The cutting surfaces of the first cutting edge 311 and the second cutting edge 321 are arranged opposite to each other.

[0054] The chamfering tool of this application mainly consists of a tool shaft 100, a tool holder 200, and a tool head 300. The tool head 300 is provided with a cutting edge, which is composed of a first cutting edge 311 and a second cutting edge 321. Specifically, the first cutting edge 311 and the second cutting edge 321 are arranged at an included angle and their cutting surfaces face each other, that is, the first cutting edge 311 and the second cutting edge 321 form a V-shaped cutting edge, making the cutting edge a V-shaped cutting structure. For a detailed working principle, please refer to [reference needed]. Figure 1 The cutting edge is close to the right angle on the same height side of the PCB board. The first cutting edge 311 and the second cutting edge 321 simultaneously chamfer the two right angles, which can ensure that the processing of all chamfers on the same PCB board is consistent.

[0055] The included angle between the first cutting edge 311 and the second cutting edge 321 can be designed according to the thickness of the PCB board. This application does not specifically limit the included angle between the first cutting edge 311 and the second cutting edge 321.

[0056] Specifically, the cutter head 300 includes a first cutter body 310 and a second cutter body 320. A first cutting edge 311 is disposed on the first cutter body 310, and a second cutting edge 321 is disposed on the second cutter body 320.
