Description

Technical Field

[0001] This utility model relates to the field of perforation device technology, and in particular to a perforation device for audio circuit boards. Background Technology

[0002] Audio circuit boards require through-holes during manufacturing to connect electronic components. Through-holes are a key process in circuit board manufacturing, allowing signals to be connected between different layers, thus enabling the construction of complex circuits. In the through-hole processing of audio circuit boards, a high-speed rotating drill is used to cut the through-hole diameter.

[0003] In existing technologies, for boards that need to be processed in batches, insufficient pressure causes the board to vibrate and shift during drilling, while excessive pressure causes local deformation of the board. Moreover, traditional equipment often involves processing and loading / unloading at the same station, requiring the replacement of the next board only after drilling is completed. This results in low overall processing efficiency and makes it difficult to meet the needs of mass production. Therefore, we propose a perforation device for audio circuit boards to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a perforation device for audio circuit boards.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A perforation device for audio circuit boards includes a PCB drilling machine body. A mounting plate is fixedly connected inside the PCB drilling machine body. A stepper motor is fixedly connected to the top of the mounting plate. A turntable is fixedly connected to the top of the stepper motor's output shaft. Two PCB placement molds are fixedly embedded in the top of the turntable. Two positioning posts and two cylinders are fixedly connected to the top of the turntable. T-shaped sleeves and springs are slidably fitted onto the outer walls of the two cylinders. A U-shaped pressure plate is fixedly connected to the outer walls of the two T-shaped sleeves. A U-shaped silicone pad is fixedly connected to the bottom of the two U-shaped pressure plates. Positioning holes are formed on the outer walls of the two U-shaped pressure plates. A frame is slidably connected inside the PCB drilling machine body, and a pressing component is provided on the outer wall of the frame.

[0007] Preferably, the pressing assembly includes two cylinders, the bottom of the frame is fixedly connected to the outer wall of the two cylinders, and the bottom of the output end of each of the two cylinders is fixedly connected to a side pressure plate. By setting the pressing assembly, the side pressure plate is driven to apply downward pressure to the U-shaped pressure plate, thereby squeezing the U-shaped silicone pad to the top of the audio circuit board and limiting it to ensure that it will not slip during drilling.

[0008] Preferably, the outer wall of the PCB drilling machine body is provided with an assembly hole, and the inner wall of the assembly hole is rotatably connected to the outer wall of the stepper motor output shaft.

[0009] Preferably, the bottom of the two T-shaped sleeves is fixedly connected to the top of the two springs, and the bottom of the two springs is fixedly connected to the top of the turntable.

[0010] Preferably, a drilling spindle is fixedly connected to the bottom of the frame.

[0011] Preferably, the inner walls of the two positioning holes are slidably connected to the outer walls of the two positioning posts, respectively.

[0012] Compared with the prior art, the advantages of this utility model are:

[0013] This solution achieves smooth vertical movement by using a U-shaped pressure plate with the cooperation of a T-shaped sleeve and a cylinder. After moving upwards and disengaging from the positioning column, it can rotate to avoid obstacles, facilitating quick loading and unloading. A cylinder drives the side pressure plate to press down on the U-shaped pressure plate, which, together with the bottom U-shaped silicone pad, acts on the audio circuit board to avoid damage to the surface and internal circuitry of the board from hard contact, ensuring the integrity of the board after processing. A stepper motor drives the turntable to rotate, successfully achieving independent separation between the processing station and the loading and unloading station. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Depend on Figures 1-4 As shown, a drilling device for audio circuit boards is disclosed, including a PCB drilling machine body 1. A mounting plate 2 is fixedly connected inside the PCB drilling machine body 1, and a stepper motor 3 is fixedly connected to the top of the mounting plate 2. An assembly hole is opened on the outer wall of the PCB drilling machine body 1, and the inner wall of the assembly hole is rotatably connected to the outer wall of the output shaft of the stepper motor 3. A turntable 4 is fixedly connected to the top of the output shaft of the stepper motor 3. An encoder is installed on the output shaft of the stepper motor 3, which can drive the turntable 4 to rotate to a designated position, so as to accurately transfer the audio circuit board to be processed to the bottom of the drilling spindle 14.

[0022] Two PCB board placement molds 5 are fixedly embedded on the top of the turntable 4. The structure of the two PCB board placement molds 5 realizes the separation of the processing station and the loading and unloading station. When the drilling spindle 14 is processing at one station, loading and unloading operations can be performed at the other station without waiting for the processing to be completed before changing materials.

[0023] The top of the turntable 4 is fixedly connected to two positioning posts 6 and two cylinders 7. The outer walls of the two cylinders 7 are slidably fitted with T-shaped sleeves 8 and springs 9. The T-shaped sleeves 8 can slide vertically along the cylinders 7 to ensure the stability of the return plate 10 when it moves up and down and to prevent it from tilting during the movement.

[0024] The bottoms of the two T-shaped sleeves 8 are fixedly connected to the tops of the two springs 9 respectively. The bottoms of the two springs 9 are fixedly connected to the top of the turntable 4. When the return plate 10 is rotated, the spring 9 will generate torsional elastic force. After the return plate 10 is released, the elastic force can drive the return plate 10 to automatically reset, so that the positioning hole 12 re-fits with the positioning post 6.

[0025] Both T-shaped sleeves 8 have a U-shaped pressure plate 10 fixedly connected to their outer walls, and both U-shaped pressure plates 10 have a U-shaped silicone pad 11 fixedly connected to their bottoms. When the cylinder 15 drives the side pressure plate 16 to press down, the pressure can be evenly transmitted to the U-shaped silicone pad 11 at the bottom, and then act on the audio circuit board.

[0026] The outer walls of the two U-shaped pressure plates 10 are provided with positioning holes 12. The inner walls of the two positioning holes 12 are slidably connected to the outer walls of the two positioning posts 6 respectively. The PCB drilling machine body 1 is slidably connected to the frame 13. The existing cross slide is installed inside the PCB drilling machine body 1, and the frame 13 is fixed on the cross slide and moves through the cross slide. The bottom of the frame 13 is fixedly connected to the drilling spindle 14.

[0027] The outer wall of the frame 13 is provided with a pressing assembly, which includes two cylinders 15. The bottom of the frame 13 is fixedly connected to the outer wall of the two cylinders 15. The bottom of the output end of the two cylinders 15 is fixedly connected with a side pressure plate 16. The air inlet of the two cylinders 15 is controlled by an existing three-position five-way solenoid valve or solenoid valve, which can achieve synchronous control.

[0028] Working principle: In use, the return plate 10 on the left end of the turntable 4 is moved upward. The return plate 10 moves vertically upward through the T-shaped sleeve 8 and the cylinder 7, causing the positioning post 6 to disengage from the positioning hole 12. Then, the return plate 10 is rotated to expose the top of the PCB board placement mold 5 on the left end, making it easier to place the audio circuit board to be processed into the PCB board placement mold 5 on the left end. At this time, the spring 9 rotates and generates torsional elasticity, which resets the return plate 10 when it is released. The return plate 10 is then slid back into the positioning post 6 from top to bottom through the positioning hole 12. The positioning post 6 and the T-shaped sleeve 8 and the cylinder 7 work together to make the U-shaped pressure plate 10 move only up and down and not horizontally or rotate. As the stepper motor 3 runs, it drives the turntable 4 to rotate and move the audio circuit board to be processed to the bottom of the drilling spindle 14. Then the stepper motor 3 stops running and the two cylinders 15 run to drive the two side pressure plates 16 to move downward. The two side pressure plates 16 move downward and press the U-shaped pressure plate 10 downward, so that the bottom U-shaped silicone pad 11 is squeezed to the top of the audio circuit board and its position is fixed. The drilling spindle 14 drills holes in the outer wall of the audio circuit board.

[0029] It should be noted that, in actual use, an existing PLC controller can be added. The PLC controller is electrically connected to the PCB drilling machine body 1, stepper motor 3, and cylinder 15 to facilitate overall control.
