[0002] Drilling machines are a general term for machines and equipment that use tools harder and sharper than the target material to leave cylindrical holes or openings in the target material through rotary cutting or rotary extrusion. In the electronics manufacturing industry, circuit boards are a key component of electronic devices, and their processing quality directly affects the performance and stability of electronic products. Among these processes, the circuit board drilling process is extremely important. Precise drilling ensures the accurate installation of subsequent electronic components and good connections between circuits, playing a crucial role in ensuring the normal operation of the entire electronic system.

[0003] For example, the circuit board drilling machine disclosed in Chinese Patent No. CN221850435U works as follows: "It includes a conveyor frame, a fixed frame fixedly mounted on the back of the conveyor frame, a servo motor fixedly mounted on the top of the fixed frame, the output shaft of the servo motor passing through the fixed frame and mounting a drill bit, and a feeding assembly for conveying and transferring the circuit board within the inner cavity of the conveyor frame. This invention uses the feeding assembly to convey and transfer the circuit board. When a sensor detects the position of the circuit board, an electrical signal is sent through the control cabinet, and then the conveying assembly stops conveying." The lifting assembly lifts the support platform, bringing the circuit board closer to the drill bit for easier drilling. Simultaneously, the steering and adjustment assemblies can adjust the position of the circuit board on top of the support platform, facilitating multiple drilling operations, avoiding repeated feeding and drilling, shortening drilling time, and improving the drilling efficiency of the circuit board drilling machine.

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the following provides a more detailed description of the utility model. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the utility model.

[0016] Please see Figure 1-4 This utility model provides a technical solution: a drilling and positioning device for circuit boards, including a fixing plate 10, a drilling column 11 fixedly installed on the top of the fixing plate 10, a rotating groove 12 opened at the bottom of the drilling column 11, a fixing frame 13 is installed inside the rotating groove 12 by a motor; a telescopic motor 14 is connected above the fixing frame 13 by a moving component, and a drill bit 15 is provided at the telescopic end of the telescopic motor 14; a placement groove 30 is opened on the upper surface of the drilling column 11, an installation groove 31 is opened inside the placement groove 30, and a fixing component for fixing the circuit board is provided inside the installation groove 31.

[0017] In this embodiment, the fixed plate 10 provides a stable support foundation for the entire device, ensuring that the device will not shake or shift during drilling, thus guaranteeing drilling stability. The drilling column 11 is installed above the fixed plate 10, with a rotating groove 12 and a fixed frame 13 at its bottom. This structure allows the fixed frame 13 to rotate within the rotating groove 12 under the drive of a motor, thereby driving the telescopic motor 14 and the drill bit 15 above to adjust their angles. This can meet the drilling requirements at different angles, improving the applicability and flexibility of the device. The telescopic motor 14 is installed on the fixed frame 13, and its telescopic end is provided with... The drill 15, through the telescopic movement of the telescopic motor 14, can precisely control its up and down movement, achieving accurate adjustment of the drilling depth and ensuring that the drilling depth meets the design requirements, thus improving drilling accuracy. Furthermore, the mounting slot 31 is equipped with a fixing component for fixing the circuit board, providing a stable placement platform 37 for the circuit board and effectively fixing it. The separately controlled fixing component facilitates the fixing of circuit boards of different shapes, preventing the circuit board from moving or shaking during the drilling process, further ensuring the accuracy and quality of drilling.

[0018] Specifically, the moving component includes a lead screw 21, a moving block 22, a slider 24, and a connecting plate 25. A moving groove 20 is provided on the bottom surface above the telescopic motor 14. The lead screw 21 is installed inside the moving groove 20 through the rotation of the motor. The moving block 22 is movably installed inside the moving groove 20. The moving block 22 is threaded around the lead screw 21 and is fixedly connected to the upper surface of the telescopic motor 14.

[0019] In this embodiment, a moving groove 20 is opened on the bottom surface above the telescopic motor 14 and a lead screw 21 is set. The motor drives the lead screw 21 to rotate. Utilizing the threaded transmission relationship between the lead screw 21 and the moving block 22, the rotational motion of the lead screw 21 is converted into the linear motion of the moving block 22. Since the moving block 22 is fixedly connected to the upper surface of the telescopic motor 14, it drives the telescopic motor 14 to move precisely in the horizontal direction, thereby achieving precise positioning of the drill 15 in the horizontal direction. This can meet the drilling requirements at different positions. By controlling the rotation of the lead screw 21 through the motor, the moving distance and speed of the moving block 22 can be precisely controlled, thereby precisely controlling the position of the telescopic motor 14 and the drill 15. This improves the accuracy and stability of drilling positioning, facilitates automated control, and improves production efficiency.

[0020] Specifically, the fixing components include an annular toothed plate 33, an electric telescopic block 34, and a fixing block 36. The mounting groove 31 has several rotating grooves 32 inside, and the annular toothed plate 33 is rotatably arranged inside the rotating grooves 32. The electric telescopic block 34 is movably arranged inside the mounting groove 31. The contact surface between the electric telescopic block 34 and the inner surface of the mounting groove 31 is provided with tooth grooves, and the tooth grooves mesh with the annular toothed plate 33. An inclined groove 35 is provided on one side of the electric telescopic block 34. The fixing block 36 is movably arranged inside the inclined groove 35 by a driving motor. A placement platform 37 is provided on the electric telescopic block 34 below the inclined groove 35.

[0021] In this embodiment, a rotating groove 32 is formed inside the mounting groove 31, and an annular toothed plate 33 is provided. The contact surface between the electric telescopic block 34 and the inner surface of the mounting groove 31 is provided with a toothed groove and meshes with the annular toothed plate 33. When the annular toothed plate 33 rotates under the drive of the motor, it can drive the electric telescopic block 34 to make linear motion within the mounting groove 31, thereby achieving precise control of the position of the electric telescopic block 34 and adjusting the position of the fixing block 36 to adapt to the fixing requirements of circuit boards of different sizes. Moreover, the annular toothed plate 33 inside different mounting grooves 31 meshes with different electric telescopic blocks 34, so that each electric telescopic block 34 can be controlled individually, which is convenient for fixing circuit boards of different shapes. An oblique groove is formed on one side of the electric telescopic block 34. The device uses a groove 35 and a moving motor to set a fixing block 36. When fixing the circuit board, the motor drives the fixing block 36 to move along the groove 35, which can fix the circuit board, increasing the stability and reliability of the fixing. At the same time, a placement platform 37 is opened on the electric telescopic block 34 below the groove 35, providing a stable support surface for the circuit board, further ensuring the stability of the circuit board during the drilling process. It can achieve fast and stable fixing of the circuit board, and the fixing force is adjustable, which can adapt to circuit boards of different thicknesses and materials, improving the versatility and applicability of the device, effectively ensuring the stability of the circuit board during the drilling process, and improving the drilling quality.

[0022] Specifically, the telescopic motor 14 has sliding grooves 23 on both sides of its upper end, and a slider 24 is movably arranged inside the sliding grooves 23. Connecting plates 25 are fixedly arranged on both sides of the telescopic motor 14, and the connecting plates 25 are fixedly connected to the slider 24.

[0023] In this embodiment, slide grooves 23 are provided on both sides of the upper end of the telescopic motor 14, and sliders 24 are provided. The sliders 24 can slide freely in the slide grooves 23. When the telescopic motor 14 moves horizontally under the drive of the moving component, the sliders 24 slide in the slide grooves 23, providing guidance for the movement of the telescopic motor 14 and preventing the telescopic motor 14 from deviating or shaking during the movement, thus ensuring the stability and accuracy of the movement of the telescopic motor 14. Connecting plates 25 are fixedly provided on both sides of the telescopic motor 14 and are fixedly connected to the sliders 24. The connecting plates 25 serve to connect the telescopic motor 14 and the sliders 24, enhancing the overall integrity and stability of the structure, enabling the sliders 24 to better drive the telescopic motor 14 to move, and also better withstand the force generated by the telescopic motor 14 during the movement, thus improving the reliability and durability of the device.

[0024] Specifically, the front end of fixed block 36 is made of a soft material.

[0025] In this embodiment, when the fixing block 36 fixes the circuit board, the soft material can play a buffering and protective role, avoiding direct hard contact between the fixing block 36 and the circuit board, preventing scratches or damage to the surface of the circuit board, and ensuring the quality and integrity of the circuit board. At the same time, the soft material can also increase the friction between the fixing block 36 and the circuit board, further improving the stability of the fixation.

[0026] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
