[0024] The cleaning mechanism also includes a two-way small blower 19 fixedly mounted on the top of the driving plate 5, the output end of the two-way small blower 19 extends to the inside of the cleaning shell 7, the inside of the cleaning shell 7 is provided with an air cavity 20, the inside of the cleaning shell 7 is provided with a plurality of air holes 21, the plurality of air holes 21 are arranged in a circumferential manner, and a rubber pad 30 is fixedly connected to the bottom of the cleaning shell 7. The cleaning mechanism is provided so that the two-way small blower 19 is started when drilling, and air is sucked from the inside through the plurality of air holes 21. Since the angle of the rubber pad 30 is tilted inward, a certain gap is formed on one side of the rubber pad 30 after contacting the circuit board. The gap allows air to enter the interior of the cleaning shell 7 through the gap, and the air outside the cleaning shell 7 enters the interior to drive the debris to move toward the center of the cleaning shell 7, preventing the debris from scattering around during drilling and scratching the surface of the circuit board. After the drilling is completed, the two-way small blower 19 is started in reverse to restart the interior of the cleaning shell 7. At this time, due to the inward inclination of the angle of the rubber pad 30, one side of the rubber pad 30 is more closely attached to the circuit board, so that air can enter the bottom through the hole just drilled, and at the same time, the cut debris will be brought to the bottom by the flow of air, completing the cleaning of the surface of the circuit board.
[0025] The driven mechanism also includes two sliding rods 8 slidably connected to the bottom of the inner wall of the transverse moving plate 3, the two sliding rods 8 are symmetrically arranged, and the outsides of the two sliding rods 8 are movably sleeved with driven springs 9, and the tops of the two sliding rods 8 are fixedly connected to the same driven plate 10, and the top of the driven plate 10 is fixedly connected to two driven rods 11, the two driven rods 11 are symmetrically arranged, and the tops of the two driven rods 11 are fixedly connected to the bottom of the mounting plate 4, and the outsides of the two driven rods 11 are movably sleeved with fastening springs 12, and the driving plate 5 is slidably connected to the outsides of the two driven rods 11. Specifically, the tops of the two fastening springs 12 are fixedly connected to the bottom of the driving plate 5, so that the driving plate 5 is driven to move when one end of the mounting plate 4 is installed, so that the cleaning shell 7 can be fitted with the circuit board without adding a driving device.
[0026] The driving mechanism includes two fixing rings 13 fixedly connected to the top of the driving plate 5, and the interiors of the two fixing rings 13 are slidably connected with rotating rods 14, and driving blocks 15 are provided on the opposite sides of the two rotating rods 14, and the driving blocks 15 are adapted to the bottom of the mounting plate 4, and torsion springs 16 are provided at both ends of the driving blocks 15.

[0027] The fixing mechanism includes a collecting shell 22 connected to the top of the shell 1, and two sliding frames 23 are fixedly connected to the top of the collecting shell 22. The two sliding frames 23 are symmetrically arranged, and fixed slide bars 24 are fixedly connected to both sides of the inner walls of the two sliding frames 23. The outsides of the two fixed slide bars 24 are slidably connected to two fixed slide plates 25. The outsides of the two fixed slide plates 25 are movably sleeved with two fixing springs 26, and one end of the four fixing springs 26 is fixedly connected to one side of the corresponding fixing slide plates 25, and the other ends of the four fixing springs 26 are fixedly connected to one side of the inner wall of the corresponding sliding frame 23, so that the circuit board is placed on the corresponding side of the two fixed slide plates 25, and then the circuit board can be tightened and fixed by extending the four fixed springs 26.
[0028] The bottom of the collecting shell 22 is arranged at an angle, and a cutting guide groove 27 is provided at the bottom of the collecting shell 22. A collecting box 28 is slidably connected to the bottom of the inner wall of the shell 1, and an inclined plate 29 is fixedly connected to the top of the collecting box 28. The inclined plate 29 and the cutting guide groove 27 are adapted to each other, so that the bottom of the collecting shell 22 is arranged at an angle to facilitate the collection of debris, and the debris can be quickly cleaned after collection through the rear collecting box 28.
[0029] Working principle: First, pull the two fixed slides 25 apart. The movement of the two fixed slides 25 compresses the four fixed springs 26. At this time, place the circuit board between the two fixed slides 25. At this time, release the two fixed slides 25, so that the four fixed springs 26 extend, so that the two fixed slides 25 clamp and fix the circuit board. At this time, align the output end of the drill rig 31 with the position where the hole needs to be drilled, and move the mounting plate 4 downward. The movement of the mounting plate 4 drives the drill rig 31 to move. At the same time, the movement of the mounting plate 4 drives the two driven rods 11 to move. The movement of the two driven rods 11 drives the driven rods 11 to move. The plate 10 moves, and the driven plate 10 moves to drive the two sliding rods 8 to slide inside the transverse moving plate 3, so that the two driven springs 9 are compressed, so that the driving plate 5 is driven to move downward. When it moves to the position where a hole needs to be drilled, the driving handle 17 is rotated, and the driving handle 17 rotates to drive the rotating rod 14 to rotate, and the rotating rod 14 rotates to drive the torsion spring 16 to rotate, and the torsion spring 16 rotates to drive the driving block 15 to rotate, so that one end of the driving block 15 contacts the bottom of the mounting plate 4, so that the driving plate 5 slides outside the two driven rods 11, so that the fastening spring 12 is compressed, and the rubber pad 30 is pressed. One side of the rubber pad 30 is tightly fitted with the top of the circuit board. At this time, the fixing block 32 is fixed inside the fixing frame 33 to drill holes. During the drilling process, the two-way small blower 19 is started to evacuate the inside of the air cavity 20 through the plurality of air holes 21. At this time, since the angle of the rubber pad 30 is tilted inward, there is a certain gap between one side of the rubber pad 30 and the circuit board, so that air can enter the inside of the cleaning shell 7 through the gap, so that the air outside the cleaning shell 7 enters the inside and drives the debris to move to the center of the cleaning shell 7, preventing the debris from floating around when drilling. After the drilling is completed, the two-way small blower 19 is started in reverse to restart the inside of the cleaning shell 7. At this time, due to the inward inclination of the rubber pad 30, one side of the rubber pad 30 is more closely attached to the circuit board, so that air can enter the bottom through the hole just drilled, and at the same time, the cut chips are brought to the bottom by the flow of air to complete the cleaning of the surface of the circuit board. At this time, the chips enter the interior of the collection box 28 through the guide groove 27 at the bottom of the collection shell 22 and the inclined plate 29 at the top of the collection box 28 to complete the cleaning of the drilled hole.
