[0025] 2.

[0026] 3.

[0045] This embodiment also provides a method for using a drill cleaning device for circuit board drilling, comprising the following steps:

[0046] S1: First, turn on the power supply, place the circuit board to be punched on the placement table 11, mark the desired punching position and fix it on the placement table 11, then start the drilling motor 42, and adjust the position of the mounting plate 3 through the cooperation of the linear motor 31, the adjustment motor 24, the screw rod 21, the pulley 22 and the belt 23, so that the punching drill 43 can be adjusted to the position just above the desired punching position;

[0047] S2: The mounting base 41 is controlled to move downward by the electric cylinder 4. When the mounting base 41 is controlled to move downward by the electric cylinder 4, the two protective covers 5 can be controlled to move away from each other by the two support rods 7, so that the two protective covers 5 can be in an open state, which will not affect the normal drilling operation of the drilling drill 43. At the same time, as the two protective covers 5 are opened, the lifting plate 61 can be controlled to slide upward and close the strip opening on the inner wall of the top side of the hollow plate 6 under the cooperation of the tooth plate 73, the gear 72 and the support pin.

At the same time, the outside air enters the hollow plate 6 through the strip opening below the hollow plate 6, so that the waste chips generated by the drilling drill 43 during the drilling operation can be directly sucked into the hollow plate 6, and then enter the annular box 8 with the air flow through the hose 85. Under the action of the filter plate 84, the waste chips can be intercepted in the annular box 8 and temporarily stored in the annular box 8, which can not only prevent the waste chips from remaining on the circuit board, but also prevent the waste chips from affecting the normal operation of the exhaust fan 81.

[0048] S3: After the drilling is completed, the mounting seat 41 is controlled by the electric cylinder 4 to move upward, so that the drilling drill 43 can be stored in the space surrounded by the two protective covers 5. At the same time, the two protective covers 5 are closed with the cooperation of the two support rods 7, and the cleaning brush 92 can be brought into contact with the drilling drill 43. Due to the closing of the two protective covers 5, the lifting plate 61 will also reset downward and close the lower strip opening in the hollow plate 6, so that the air flow rate at the upper strip opening and the rectangular opening can be increased, and the fan blades 93 can provide a certain driving force for the rotating shaft 91, and the drilling can be completed at the same time. The continuous rotation of the drill bit 43 can form a state of relative motion with the rotating shaft 91, so that the drilling drill bit 43 can be cleaned, and the waste chips cleaned by the drilling drill bit 43 are sucked into the hollow plate 6 through the multiple strip openings on the top. The waste chips that fall on the two protective covers 5 close to each other will enter the hollow plate 6 through the strip openings above the wedge strip 601 under the guidance of the wedge strip 601, and will be extracted into the annular box 8 for temporary storage under the continuous suction action of the exhaust fan 81. After the drilling is completed, the slag discharge pipe is opened to discharge the waste chips in the annular box 8.
