[0002] Since PCBs are widely used, basically any electrical device uses a PCB board. Therefore, the structure of the PCB board is very complex. For some special assemblies or special components, special-shaped holes need to be set during the PCB manufacturing process.

[0003] The invention with the application number CN202111168901.8 discloses a PCB board drilling device convenient for dust removal, including side plates and a C-shaped frame. There are two side plates which are arranged in parallel, and a conveyor belt is rotated between the two side plates and is horizontally arranged. Both ends inside the conveyor belt are provided with round rollers and are horizontally arranged. The two vertical sides of the C-shaped frame are installed on the tops of the two side plates through bolts. A box body is installed on the top of the horizontal side of the C-shaped frame through bolts. A sliding plate is slid inside the box body and is horizontally arranged. An up-and-down moving mechanism for moving the sliding plate up and down is arranged inside the box body. And limiting mechanisms for limiting the sliding plate are arranged at both ends of a pair of symmetry inside the box body. A rotating rod is rotated directly above the horizontal side of the C-shaped frame and is horizontally arranged. And fixing blocks are fixed at the centers of the bottoms of the two side plates. A brush roller is rotated between the two fixing blocks and is horizontally arranged.

[0027] The following describes the present utility model in detail with reference to the accompanying drawings.

[0028] As Figures 1-3 shown, a PCB board X - RAY transmission drilling mechanism includes a drilling tool 20 located on one side of the PCB board, and a guide cylinder 22 is arranged on the other side of the PCB board. The guide cylinder 22 is provided with a guiding drill hole 23 for guiding the drilling tool 20 to enter, and the guiding drill hole 23 of the guide cylinder 22 is provided with a strip 17 through which the drilling tool 20 passes when drilling.

[0029] The PCB board is located between the drilling tool 20 and the guide cylinder 22. The strip 17 is attached to the guiding drill hole 23 of the guide cylinder 22, and the PCB board is simultaneously attached to the strip 17. When drilling, after the drilling tool 20 passes through the PCB board, the drilling tool 20 simultaneously passes through the strip 17 and enters the guiding drill hole 23 of the guide cylinder 22. The strip 17 cooperates with the guide cylinder 22 to be able to press the hole position of the PCB board. When the drilling tool 20 passes through, the hole position will not be deformed. With the buffering of the strip 17, the generation of burrs can be reduced, and the drilling quality of the PCB board can be improved.

[0030] The strip 17 can prevent the generation of burrs at the hole position of the PCB board.

[0031] The drilling tool 20 and the guide cylinder 22 are longitudinally coaxially aligned. Among them, the drilling tool 20 is located below the guide cylinder 22. When drilling, the drilling tool 20 passes through the PCB board from bottom to top. The strip 17 cooperates with the guide cylinder 22 to be able to press the hole position at the top of the PCB board. When the drilling tool 20 passes through, the hole position will not be deformed. With the buffering of the strip 17, the generation of burrs can be reduced, and the drilling quality of the PCB board can be improved.

[0032] Preferably, according to requirements, the positions of the drilling tool 20 and the guide cylinder 22 can be interchanged. During drilling, the drilling tool 20 passes through the PCB board from top to bottom; or the drilling tool 20 and the guide cylinder 22 can be arranged horizontally, and the drilling tool 20 passes through the PCB board from left to right or from right to left to drill the PCB board.

[0033] Specifically, the drilling mechanism further includes a winding mechanism 11 for installing the tape 17. The winding mechanism 11 includes a first winding reel 12 and a second winding reel 13. The tape 17 intermittently moves from the first winding reel 12 to the second winding reel 13. During punching, the second winding reel 13 rotates to wind up the tape 17. Each time a hole is punched, the tape 17 moves a distance greater than the diameter of one hole, so that after the drilling tool 20 passes through the PCB board, it can contact the tape 17. By making the tape 17 fit the hole position, burrs can be prevented from being generated at the hole positions of the PCB board.

[0034] The drilling mechanism further includes a top driving arm 1 for installing the guide cylinder 22. The top driving arm 1 is equipped with a height adjusting member 19 for adjusting the height of the guide cylinder 22. The height of the guide cylinder 22 can be adjusted through the height adjusting member 19 to facilitate adaptation to PCB boards of different thicknesses.

[0036] Furthermore, the winding mechanism 11 further includes a plurality of winding wheels 18 installed on the top driving arm 1. The top driving arm 1 is equipped with a sliding table 2 flush with the bottom surface of the guide cylinder 22. One of the winding wheels 18 is installed on one side of the sliding table 2. The tape 17 can move along the sliding table 2. Driven by the winding wheel 18, the tape 17 can move along the winding wheel 18 and the sliding table 2 and pass through the guide cylinder 22.

[0037] The sliding table 2 is formed with a through hole 21 coaxially aligned with the guide cylinder 22. The guide cylinder 22 is installed in the through hole 21, so that the bottom of the guide cylinder 22 is flush with the bottom of the sliding table 2. One of the winding wheels 18 is installed on the left side of the sliding table 2. The right side of the sliding table 2 is formed with an arc surface 24 for the tape 17 to fit through. The arc surface 24 can prevent the tape 17 from breaking when passing through the sliding table 2. When the tape 17 moves along the bottom of the sliding table 2, it will also slide and fit with the guide cylinder 22, ensuring the guiding drilling 23 of the tape 17 and the guide cylinder 22 for the drilling tool 20 to contact after drilling.

[0038] A bottom driving seat 25 is installed at the bottom of the top driving arm 1, and the second material reel 13 is installed on the bottom driving seat 25. One or more winding wheels 18 are installed beside the second material reel 13. The material strip 17 after punching enters the second material reel 13 along the remaining winding wheels 18. The second material reel 13 rotates and reels under the drive of the servo motor. The servo motor can drive the second material reel 13 to rotate intermittently to ensure the utilization rate of the material strip 17.

[0039] Furthermore, a first guide wheel 14 and a second guide wheel 15 are installed on the right side of the sliding table 2, and the material belt 17 passes between the first guide wheel 14 and the second guide wheel 15. The top driving arm 1 is laterally provided with a lateral moving member 16 for driving the second guide wheel 15 to approach or move away from the first guide wheel 14; the material belt 17 after unloading passes between the first guide wheel 14 and the second guide wheel 15, and under the drive of the lateral moving member 16, the second guide wheel 15 can approach or move away from the first guide wheel 14. When the friction force needs to be adjusted, the second guide wheel 15 can be moved to cooperate with the first guide wheel 14 to clamp the material belt 17 to prevent it from continuing to move forward.

[0040] Preferably, the transverse moving member 16 is a telescopic cylinder arranged transversely.

[0041] The drilling mechanism includes a bottom driving seat 25 for installing the drilling tool 20. The bottom driving seat 25 is provided with a driving tool seat 26 for installing the drilling tool 20 and a lifting power member 27 for driving the drilling tool 20 to move longitudinally. The lifting power member 27 is a linear module or a lifting cylinder. Driven by the lifting power member 27, the drilling tool 20 can move in the vertical direction to drill holes in the PCB located above.
