[0020] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0021] Referring to Figures 1-4, the PCB board router cooling device of this embodiment includes: a support leg 1, a bearing base plate 2 fixedly connected to the upper surface of the support leg 1, a guide rail 3 fixedly connected to the upper surface of the bearing base plate 2, an airflow conveying bellows 4 slidably connected to the upper surface of the guide rail 3, a quick-connect interface 5 fixedly connected to the side surface of the airflow conveying bellows 4, and a directional blowing nozzle 6 fixedly connected to the outer surface of the quick-connect interface 5. A sealing cover 8 is movably connected to the upper surface of a cooling medium storage tank 7, a pressurizing booster pump 9 is fixedly connected to the upper surface of the sealing cover 8, a main conveying cooling pipe 10 is fixedly connected to the upper surface of the pressurizing booster pump 9, a heat exchange cooling coil 11 is fixedly connected to the main conveying cooling pipe 10, and the heat exchange cooling coil 11 is fixedly connected to the inner surface of the airflow conveying bellows 4. Support legs 1 support the load-bearing base plate 2, keeping the guide rail 3 and the airflow conveying box 4 above at a stable height; the cooling medium storage box 7 is sealed by the sealing cover 8, and the internal cooling medium is pressurized by the pressurizing booster pump 9 and then sent by the main conveying first cooling pipe 10 into the heat exchange cooling coil 11 located in the airflow conveying box 4. When the airflow conveying box 4 moves along the guide rail 3, the directional blowing nozzle 6 connected by the quick connection interface 5 accurately blows the airflow cooled by the heat exchange cooling coil 11 to the target position.

[0022] A worktable 12 for placing workpieces is fixedly connected to the upper surface of the support base plate 2. A negative pressure dust collection hood 13 for dust adsorption is fixedly connected to the end of the support base plate 2 away from the cooling tank 7 for storing cooling medium, and a waste collection box 14 is fixedly connected to the lower surface of the negative pressure dust collection hood 13. A travel limiting block 15 is fixedly connected to the end of the guide rail 3 away from the cooling tank 7 for storing cooling medium. The support base plate 2 simultaneously supports the worktable 12 for placing workpieces and the negative pressure dust collection hood 13 for dust adsorption. When the workpiece to be processed is placed on the worktable 12, the dust generated during processing is adsorbed by the negative pressure dust collection hood 13 and falls into the waste collection box 14. The travel limiting block 15 on the guide rail 3 cooperates with the air box 4 for airflow to prevent it from slipping off the guide rail and ensure that the working range of the directional blowing nozzle 6 is controllable.

[0023] The outer surface of the cooling tank 7 for storing cooling medium is provided with a medium injection inlet 16 and a medium discharge outlet 17. A filter screen 18 for impurity filtration is fixedly connected to the inner surface of the medium discharge outlet 17. The outer surface of the airflow conveying box 4 is provided with a medium return port 19, which is fixedly connected to the medium discharge outlet 17 via an auxiliary conveying second cooling pipe 20. Thermal grease 21 for heat dissipation enhancement is fixedly connected to the outer surface of the cooling tank 7 for storing cooling medium. The main conveying first cooling pipe 10 is fixedly connected to the heat exchange cooling coil 11 via the medium injection inlet 16. The medium in the cooling medium storage tank 7 enters the main conveying first cooling pipe 10 through the medium injection inlet 16, flows to the heat exchange cooling coil 11 to complete heat exchange, and then flows back from the medium return inlet 19 through the auxiliary conveying second cooling pipe 20 and the medium outlet 17. The impurity filtration filter screen 18 filters the impurities in the returned medium. The cooling medium storage tank 7 accelerates heat dissipation through the heat dissipation enhancement thermal grease 21 on the outer surface, forming a circulation system of the cooling medium between the cooling tank and the coil in the air box.

[0024] Working Principle: Upon initial use, the operator first injects an appropriate amount of cooling medium into the cooling tank through the medium inlet. The sealing cover is then closed to ensure a tight seal. The PCB board to be processed is then placed on the workpiece placement table on the base plate, ensuring its stability. After starting the equipment, a booster pump pressurizes the cooling medium in the cooling tank, which is then sent through the main conveying pipe and the inlet to the heat exchange cooling coils in the airflow conveying box. As the cooling medium flows within the coils, it exchanges heat with the air inside the box, cooling the airflow. Simultaneously, the airflow conveying box moves along the guide rails, its movement constrained by limit blocks. Directional airflow nozzles connected via quick-connect interfaces precisely blow the cooled airflow onto the working milling cutter for cooling. The processing debris is collected by the base plate. The debris at the other end of the plate is adsorbed by the negative pressure debris suction hood and falls into the waste collection box. The cooling medium that has completed heat exchange flows out from the medium return port of the airflow conveying box, and flows back to the cooling box through the auxiliary conveying No. 2 cooling pipe and the medium outlet. During the return process, impurities are filtered by the impurity filtration screen. The heat dissipation enhancement thermal grease on the outer surface of the cooling box for storing the cooling medium accelerates the heat dissipation of the medium, so that the cooling medium forms a continuous circulation between the cooling box and the coil inside the air box, ensuring a stable and reliable cooling effect on the milling cutter.

[0025] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
