[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Refer to Figure 1 - Figure 3 , an embodiment provided by the present invention: a printed circuit board drilling guiding device, including a box body 1, a first hydraulic rod 2 fixedly connected inside the box body 1, a drilling tool 3 arranged inside the box body 1, the output end of the first hydraulic rod 2 is connected to the drilling tool 3, a fixed block 4 is fixedly connected inside the box body 1, a round rod 5 is slidably connected inside the fixed block 4, a clamping plate 6 is fixedly connected to the side wall of the round rod 5, a buffer assembly is arranged on the side wall of the clamping plate 6, and the buffer assembly is used for shrinking and buffering the circuit board. A first connecting block 8 is rotatably connected to the side wall of the fixed block 4, a second connecting block 9 is rotatably connected to the side wall of the first connecting block 8, a third connecting block 10 is rotatably connected to the side wall of the second connecting block 9, one end of the third connecting block 10 is rotatably connected to the side wall of the clamping plate 6, a fixed plate 11 is arranged on the side wall of the clamping plate 6, the side wall of the second connecting block 9 is rotatably connected to the side wall of the fixed plate 11, a connecting plate 12 is fixedly connected to the side wall of the fixed plate 11, a pushing assembly is arranged inside the box body 1, and the pushing assembly is used for pushing the clamping plate 6 to clamp and fix. A horizontal groove 17 is opened inside the box body 1. The buffer assembly includes a sponge pad 7, and the side wall of the sponge pad 7 is fixedly connected to the side wall of the clamping plate 6. The pushing assembly includes a second hydraulic rod 13, a fixed frame 14, a connecting rod 15 and a slide plate 16. The side wall of the second hydraulic rod 13 is fixedly connected inside the box body 1, the side wall of the fixed frame 14 is connected to the output end of the second hydraulic rod 13, one end of the connecting rod 15 is rotatably connected to the side wall of the fixed frame 14, the other end of the connecting rod 15 is rotatably connected to the side wall of the connecting plate 12, the side wall of the slide plate 16 is fixedly connected inside the box body 1, and the inside of the connecting plate 12 is slidably connected to the side wall of the slide plate 16;

[0032] When operating the device to drill the circuit board, it is first necessary to start the second hydraulic rod 13, which pushes the fixed frame 14 to move. The movement of the fixed frame 14 drives the connecting rod 15 to rotate, thereby pushing the connecting plate 12 to move on the side wall of the slide plate 16 and then slide inside the transverse groove 17. During the sliding process of the connecting plate 12, it will simultaneously drive the fixed plate 11 to move. The movement of the fixed plate 11 causes the second connecting block 9 rotatably connected to the side wall to rotate. The rotation of the second connecting block 9 further drives the first connecting block 8 and the third connecting block 10 to rotate correspondingly, thereby pushing the clamping plate 6 to move, so that the clamping plate 6 clamps and fixes the circuit board, ensuring the stability and accuracy during the drilling process. After completing the clamping and fixing, start the first hydraulic rod 2 to adjust the height of the drill 3 for precise drilling operation on the circuit board.

[0033] Refer to Figure 2 - Figure 4 As shown in Figure - 1, a water tank 18 is arranged inside the box body 1. A filter plate 19 is slidably connected inside the water tank 18. A water pump 20 is fixedly connected inside the box body 1. A water suction pipe 21 is fixedly connected to the input end of the water pump 20. A water delivery pipe 22 is fixedly connected to the output end of the water pump 20. A water outlet pipe 23 is fixedly connected to the side wall of the water delivery pipe 22. A spray head 24 is fixedly connected to the side wall of the water outlet pipe 23. One end of the water suction pipe 21 is fixedly connected inside the water tank 18. The side wall of the water outlet pipe 23 penetrates through the side wall of the box body 1 and extends to the inside. A fixing ring 25 is fixedly connected to the side wall of the water outlet pipe 23. The side wall of the fixing ring 25 is fixedly connected to the side wall of the box body 1. A drain pipe 26 is fixedly connected inside the box body 1. The side wall of the drain pipe 26 is fixedly connected inside the water tank 18;

[0034] Since high heat is generated during the operation of the drilling equipment, start the water pump 20 at this time. The water inside the water tank 18 is pumped out through the water suction pipe 21, then these waters are conveyed to the inside of the water outlet pipe 23 through the water delivery pipe 22, and then conveyed to the spray head 24 by the water outlet pipe 23. The spray head 24 sprays these water flows onto the drill 3, thereby effectively cooling the drill 3. During the cooling process, the falling water and debris enter the filter plate 19 through the holes opened inside the box body 1. The debris and impurities in the water are filtered out by the filter plate 19, so that the filtered water can re - enter the water tank 18 for recycling, saving water resources. When the filter plate 19 needs to be cleaned, it can be pulled out through the handle for cleaning. After multiple cycles of use, the water quality will decline. At this time, the water can be drained through the drain pipe 26.

[0035] Working principle: When using this device to drill a circuit board, first start the second hydraulic rod 13 to push the fixed frame 14. The movement of the fixed frame 14 drives the connecting rod 15 to rotate, and then pushes the connecting plate 12 to slide on the side wall of the slide plate 16 and slide inside the transverse groove 17. While moving, the connecting plate 12 drives the fixed plate 11 to move. The movement of the fixed plate 11 causes the second connecting block 9 fixed on the side wall to rotate. The rotation of the second connecting block 9 drives the first connecting block 8 and the third connecting block 10 to rotate, and then pushes the clamping plate 6 to move to clamp and fix the circuit board. Subsequently, start the first hydraulic rod 2 to adjust the height of the drill 3, which is convenient for drilling the circuit board.

[0036] Since high heat is easily generated during the operation of the drilling equipment, at this time, start the water pump 20 to pump out the water in the water tank 18 through the water suction pipe 21, then transport it to the inside of the water outlet pipe 23 through the water delivery pipe 22, and then transport it to the nozzle 24 by the water outlet pipe 23. The nozzle 24 sprays the water flow onto the drill 3 for cooling. Subsequently, the falling water and debris enter the filter plate 19 through the holes opened in the box body 1, and then re-enter the water tank 18 through the filtration of the filter plate 19 to achieve recycling. When the filter plate 19 needs to be cleaned, it can be pulled out through the handle for cleaning. After multiple cycles, the water quality deteriorates. At this time, the water can be discharged through the drain pipe 26.

[0037] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
