Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figure 1 The embodiments proposed in this application involve: a PCB board drilling processing device, including a base 1, a bracket 2 fixed to the upper end of the base 1, a drill rod 21 disposed on the inner side of the bracket 2 for drilling the PCB board, a movable block 22 disposed on the upper side of the drill rod 21, a lead screw 23 and a limiting rod disposed inside the movable block 22, the limiting rod passing through the interior of the movable block 22 to limit the movement of the movable block 22, the lead screw 23 being threadedly connected to the interior of the movable block 22, and a first motor 24 disposed on one side of the outer end of the bracket 2, the output shaft of the first motor 24 being connected to the lead screw 23. The specific connection method can use existing technology. A first hydraulic rod 25 is provided on the lower side of the movable block 22. A second motor 26 is fixed to the output end of the first hydraulic rod 25. The output shaft of the second motor 26 is connected to the drill rod 21. The specific connection method can use existing technology. When the first motor 24 is started to drive the lead screw 23 to rotate, it can drive the movable block 22 to move horizontally, so that the position of the drill rod 21 can be adjusted horizontally. The drill rod 21 can be raised and lowered by the lifting and lowering of the first hydraulic rod 25. After the second motor 26 is started, it can drive the drill rod 21 to rotate, so as to drill holes in the PCB board.

[0034] In this embodiment, please refer to Figure 1-3 A first support frame 3 is provided on one side of the outer end of the bracket 2. Several mounting slots 31 are evenly opened inside the first support frame 3. A third support frame 6 is fixed at the lower end of each mounting slot 31. A clamping plate 61 is provided on the upper side of the third support frame 6. One side of the PCB board can be clamped by the clamping plate 61 and the third support frame 6.

[0035] Specifically, the first support frame 3 is internally rotatably connected to a screw 7, and a third motor 71 is set on the top of the third motor 71. The output shaft of the third motor 71 is connected to the screw 7. The specific connection method can adopt existing technology. Each clamping plate 61 is threadedly connected to the screw 7, which can drive all the clamping plates 61 to rise and fall simultaneously when the screw 7 rotates, and clamp one side of the different PCB board corresponding to each clamping plate 61 at the same time.

[0036] Furthermore, a connecting plate 32 is fixed to the bottom of the first support frame 3. A drive rod 9 is threadedly connected to the inside of the connecting plate 32. The drive rod 9 is rotatably connected to the inside of the base 1. A fourth motor 91 is provided at the outer end of the base 1. The output shaft of the fourth motor 91 is connected to the drive rod 9. The specific connection method can adopt existing technology. When the drive rod 9 is driven to rotate by the fourth motor 91, the connecting plate 32 drives the first support frame 3 to move horizontally.

[0037] Two pulleys 33 are respectively provided on both sides of the bottom of the first support frame 3. At the same time, two grooves 11 corresponding to the pulleys 33 are opened on the upper surface of the base 1. When the first support frame 3 moves horizontally, the pulleys 33 can slide in the grooves 11 to keep the first support frame 3 moving smoothly and to support the movement of the first support frame 3.

[0038] In this embodiment, please refer to Figure 1 , Figure 2 and Figure 4 On the other side of the bracket 2, a second support frame 4 is provided. The interior of the second support frame 4 has several placement cavities 41 that correspond one-to-one with the mounting slot 31. The other side of the PCB board is stored through the placement cavities 41. Positioning frames 5 are provided on both sides of the interior of the placement cavity 41 to clamp and fix the two sides of the PCB board located in the placement cavity 41.

[0039] Specifically, the positioning frame 5 includes a drive plate 51 and several positioning plates 52. The drive plate 51 is located outside the second support frame 4. The positioning plates 52 are fixed to the drive plate 51. Each placement cavity 41 corresponds to two positioning plates 52, and the positioning plates 52 are slidably connected to the second support frame 4. One end of the positioning plate 52 is located inside the placement cavity 41, clamping and positioning both sides of the PCB board. Mounting brackets 53 located outside the drive plate 51 are fixed on both sides of the outer end of the second support frame 4. A second hydraulic rod 54 is provided on the inner side of the mounting bracket 53. The output end of the second hydraulic rod 54 is fixed to the drive plate 51. The positioning frame 5 moves and slides as a whole through the extension and retraction of the second hydraulic rod 54.

[0040] Furthermore, a support roller 8 is provided on the lower inner side of the positioning plate 52. The support roller 8 is rotatably connected to the inner wall of the placement cavity 41 through the support shafts on both sides, and the support roller 8 supports part of the PCB board located in the placement cavity 41.

[0041] The first motor 24, the second motor 26, the third motor 71 and the fourth motor 91 mentioned above are all servo motors.

[0042] Working principle: The PCB board to be drilled is placed into the placement cavity 41, so that one end of the PCB board enters between the clamping plate 61 and the third support frame 6. Then, the third motor 71 is started to drive the clamping plate 61 to rotate, thereby causing all the clamping plates 61 to descend at the same time, so that the same side of all the PCB boards can be clamped at the same time. At the same time, the second hydraulic rod 54 is started, so that several positioning plates 52 approach the PCB board at the same time, clamping and positioning both sides of the other end of all the PCB boards at the same time, so that the drill rod 21 can drill holes in the PCB board. Through the setting of several mounting slots 31 and placement cavity 41, multiple PCB boards can be placed at the same time, so that multiple PCB boards can be drilled at the same time, thus improving the processing efficiency through batch processing.

[0043] When it is necessary to adjust the drilling position of the PCB board, the positioning frame 5 is moved horizontally by the retraction of the second hydraulic rod 54. After the positioning plate 52 stops clamping the other side of the PCB board, the clamping plate 61 and the third support frame 6 keep clamping the PCB board. At this time, the fourth motor 91 is started to drive the drive rod 9 to rotate, thereby causing the first support frame 3 to move horizontally as a whole. The PCB board is pushed by the clamping of the third support frame 6 and the clamping plate 61, thus adjusting the drilling position of the PCB board.
