Description

Technical Field

[0002] PCB milling cutters are important tools for PCB board processing. Currently, common PCB milling cutters are mainly automated by CNC machine tools. During the processing, it is necessary to continuously spray cooling oil on the cutting tool and the PCB to be processed. Therefore, after the tool processing is completed, a layer of coolant will adhere to the surface of the tool and chips will remain in the chip groove.

[0003] An existing public patent (publication number CN215278715U) discloses a cleaning device for a PCB milling cutter. The milling cutter is clamped by a clamping mechanism and installed inside a cleaning sleeve. A small drive motor drives the driving gear and the transmission gear to rotate, thereby driving the cleaning sleeve to rotate. The milling cutter can be cleaned by brushing the bristles inside the cleaning sleeve. The operation is relatively simple, which reduces the difficulty of cleaning. The cleaning agent inside the cleaning agent tank is introduced into the cleaning sleeve through a small circulation pump, further improving the cleaning effect of the milling cutter. When cleaning the milling cutter, the milling cutter can be installed inside the cleaning sleeve for cleaning, which solves the safety hazard of previous hand-held cleaning and improves the safety of the device when used. In addition, by adding a small circulation pump, the cleaning agent can be recycled, reducing the cost of cleaning.

[0004] However, there are some problems in the cleaning process of the existing milling cutter: 1. The current cleaning device clamps the side wall of the milling cutter when positioning the milling cutter, but the clamping component will block a large area of ​​the milling cutter during the cleaning process, resulting in the clamped part of the milling cutter cannot be effectively cleaned; 2. The existing cleaning component flushes the fixed position of the milling cutter through a fixed flushing port, and cannot achieve coverage cleaning of milling cutters of different sizes, affecting the cleaning effect.
