[0018] The following examples, in conjunction with the appendix, illustrate the concepts. Figures 1-2 The technical solution of the present invention will be further described in detail below.

[0019] A circuit board drilling device includes a machine base 1. The top of the machine base 1 is provided with a movable seat and a driving mechanism 3 for driving the movable seat 2. The top of the movable seat 2 is provided with a groove 4. A slag discharge mechanism 5 is provided in the movable seat 2 below the groove 4. A locking mechanism 6 for fixing the circuit board is provided in the groove 4. A drilling mechanism 7 fixed on a frame 8 is also provided directly above the groove 4.

[0020] The drive mechanism 3 includes a boss 31, which is located on the machine base 1 behind the movable base 2. A motor I32 is provided on the boss 31, and a screw I33 is provided on the output shaft of the motor I32. The movable base 2 is provided with a connecting channel 34 that accommodates the screw I33 and screws it to it.

[0021] The locking mechanism 6 includes two sets of L-shaped seats 61, wherein positive and negative screws 62 are provided in the corresponding screw holes I on the two sets of L-shaped seats 61.

[0022] The drilling mechanism 7 includes a fixed base 71 for fixing the electric push rod 72. A screw rod II 74 driven by a motor II 73 is provided in the screw hole II on the fixed base 71. A motor III 75 is also provided on the output shaft of the electric push rod 72. A drill bit 76 is provided on the output shaft of the motor III 75.

[0023] like Figure 2 As shown, a rectangular fixed channel 9 parallel to the connecting channel 34 is provided on the rear side wall of the movable seat 2. A strip plate 10 adapted to it is provided in the fixed channel 9, and one end of the strip plate 10 is fixedly connected to the protrusion 31.

[0024] In this embodiment, a bearing for fixing the positive and negative lead screws 62 is provided on the side wall of the groove 4. One end of the positive and negative lead screws 62 extends to the outside of the movable seat 2 and is fixed with a handle. The positive and negative lead screws 62 are arranged perpendicularly to the screw II 74.

[0025] The slag discharge mechanism 5 includes a slag discharge chamber 51 disposed within the movable seat 2. A discharge port 52 communicating with the slag discharge chamber 51 is provided in the middle of the bottom wall of the groove 4. A discharge port communicating with the slag discharge chamber 51 is provided on one side wall of the movable seat 2. A sealing plug 53 is provided at the discharge port. The bottom wall of the slag discharge chamber 51 is inclined, with the bottom end of the bottom wall of the slag discharge chamber 51 located on the same side as the discharge port. The discharge port and the protrusion 31 are located on opposite sides of the movable seat 2.

[0026] The frame 8 is a U-shaped structure with its opening facing downwards. The movable seat 2 is located inside the opening of the frame 8. Bearings are provided on both ends of the fixing screw II 74 on the side wall of the frame 8. The motor II 73 is mounted on the outer wall of the frame 8. A slide rod 11 for passing through the through hole on the fixed seat 71 is also mounted inside the opening of the frame 8. When the motor II 73 drives the screw II 74 to rotate in the screw hole II to move the fixed seat 71, the through hole on the fixed seat 71 will slide on the slide rod 11. The slide rod 11 abuts against the side wall of the through hole to prevent the fixed seat 71 and the screw II 74 from rotating together.

[0027] like Figure 2 As shown, the top of the sidewall of the groove 4 is provided with a rectangular notch 12 parallel to the positive and negative lead screws 62. The frame 8 is provided with a support plate 13 that passes through the rectangular notch 12. The support plate 13 is provided with a strip-shaped operating port 14 facing the drill bit 76. The top of the support plate 13 is flush with the top of the horizontal end of the L-shaped seat 61.

[0028] When in use, motor I32 drives screw I33 to rotate in connecting channel 34, thereby driving movable seat 2 to move to the left so that its left end is suspended outside the machine base 1. At this time, the rectangular notch 12 on movable seat 2 slides to the left at the bottom of support plate 13, and the fixed channel 9 on movable seat 2 slides to the left on strip plate 10, so that people can place the circuit board between the two sets of L-shaped seats 61 in the groove 4 and above the support plate 13. By rotating the positive and negative screws 62, they can rotate in the screw hole I in the L-shaped seat 61 to reduce the distance between the two sets of L-shaped seats 61, so that they can support the circuit board and lock it. Thus, by adjusting the distance between the two sets of L-shaped seats 61, circuit boards of different sizes can be supported, fixed and locked.

[0029] Next, motor I32 drives the movable seat 2 and the circuit board above it to move slowly to the right through screw I33 and connecting channel 34. During this process, electric push rod 72 drives motor III75 and drill bit 76 to move down. Motor III75 drives drill bit 76 to rotate, which can drill holes in different areas of the circuit board in the horizontal direction. At the same time, motor II73 rotates in screw hole II through lead screw II74, which can drive fixed seat 71, electric push rod 72, motor III75 and drill bit 76 to move back and forth, thereby drilling holes in different areas of the circuit board in the vertical direction. Thus, drilling is carried out in different areas of the top of the circuit board in the above manner.

[0030] During the above process, the circuit board slides on the support plate 13, while the drill bit 76 is always located directly above the operating opening 14 during its displacement. This allows the drill bit 76 to pass through the operating opening 14 when it penetrates the circuit board. At this time, the support plate 13 not only does not obstruct the drill bit 76, but also, when the drill bit 76 is drilling, the side wall of the support plate 13 outside the operating opening 14 can support the bottom of the circuit board at the drilling location, preventing the bottom of the circuit board at the drilling area from being suspended in the air, which would result in insufficient stability and make it easy to bend the area during drilling.

[0031] After processing, the debris in the groove 4 can be swept to the discharge port 52 and flow into the slag discharge chamber 51. When the left end of the moving seat 2 is suspended outside the machine base 1, the debris in the slag discharge chamber 51 flows along the inclined surface of its inner bottom wall to the discharge port. Then, after the sealing plug 53 is opened, the debris inside flows into the collection container directly below it through the discharge port.

[0032] The present invention has been described in detail above, but the content described is only a preferred embodiment of the present invention and should not be considered as limiting the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the patent coverage of the present invention.
