Description

Technical Field

[0001] This utility model relates to the field of PCB board drilling application technology, specifically a PCB board drilling device with automatic positioning function. Background Technology

[0002] In the PCB manufacturing process, drilling is a crucial step. Traditional PCB drilling equipment mostly requires manual positioning and marking of the drilling location before operating the drilling equipment. This method is not only cumbersome, but the accuracy of manual positioning is also greatly affected by human factors, such as the operator's skill level and fatigue, which can easily lead to deviations in the drilling position, thereby affecting the quality of the PCB and reducing the product yield.

[0003] As electronic products develop towards miniaturization and high precision, the requirements for drilling accuracy on PCB boards are also increasing. Existing manual positioning drilling devices can hardly meet production needs. There is an urgent need for a device that can quickly and accurately position the drilling location to improve production efficiency and product quality and reduce production costs. Therefore, we propose a PCB board drilling device with automatic positioning function. Utility Model Content

[0004] The purpose of this invention is to provide a PCB board drilling device with automatic positioning function to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a PCB board drilling device with automatic positioning function, comprising a frame, a lifting sliding seat, a clamping structure, and a drilling structure; support rods are installed at the bottom perimeter of the frame, which support the frame and separate it from the ground or other supporting surfaces to maintain a stable standing posture. The perimeter installation method evenly distributes the overall weight of the device, preventing it from tipping over due to a shift in the center of gravity, ensuring the stability of the drilling device during operation, and providing a stable foundation for precise drilling. A shock-absorbing base plate is installed on the upper surface of the frame during drilling. During drilling, the drilling structure generates vibrations that can be transmitted to the frame, affecting drilling accuracy and stability. A vibration-damping base plate, mounted on the upper surface of the frame, effectively absorbs and buffers the vibration energy generated during drilling, reducing the impact of vibration on the frame and other components, and improving the quality and accuracy of PCB drilling. The base plate is equipped with a clamping structure, providing a stable mounting foundation and minimizing interference from vibration. The clamping structure securely holds the PCB to the base plate mechanically or electromagnetically, ensuring that the PCB does not shift due to drilling forces or other factors during drilling. To ensure accurate drilling position, a lifting sliding seat is installed on the upper surface of the frame. This seat moves vertically via an internal lifting drive mechanism. This lifting function allows the drilling structure mounted on it to be adjusted to a suitable drilling height for PCBs of different thicknesses, meeting the drilling requirements of PCBs of various sizes. A sliding groove is formed on one side wall of the lifting sliding seat, and a sliding block is installed in the groove. The groove provides a guide and track for the sliding block. Constrained by the groove, the sliding block can only move along the set direction on the side wall of the lifting sliding seat, thus ensuring accurate drilling position. The drilling structure mounted on the sliding block can be adjusted horizontally to drill holes at different locations on the PCB board. The drilling structure is mounted on the sliding block, and a PLC controller is mounted on the front surface of the lifting sliding seat. The sliding block provides the installation position and power transmission for the horizontal movement of the drilling structure. The drilling structure generally includes components such as a motor and a drill bit. The motor drives the drill bit to rotate at high speed to drill holes in the PCB board fixed on the clamping structure. Driven by the sliding block, the drilling structure can move horizontally, and driven by the lifting sliding seat, it can move vertically, enabling drilling operations at different locations and depths on the PCB board.

[0006] Preferably, the clamping structure has a threaded rod internally connected to it, and a threaded sleeve is threadedly installed around the threaded rod. The clamping structure also has a slide rail internally, and a slider is slidably connected to the bottom of the threaded sleeve inside the slide rail. A clamping plate is fixedly connected to the bottom of the slider. The clamping plate is used to fix the PCB board. By rotating the threaded rod and the threaded sleeve, the slider moves up and down along the threaded rod under the action of the threads, thereby driving the slider to slide within the slide rail, realizing the lifting and lowering of the clamping plate to accommodate PCB boards of different thicknesses.

[0007] Preferably, a clamping plate is fixedly connected to the top of the threaded sleeve, a turntable is fixedly connected to one side of the threaded rod, and a rotating rod is fixedly connected to one side of the turntable. A sponge pad is sleeved around the rotating rod. The sponge pad increases the grip comfort of the rotating rod and prevents the hand from slipping when rotating the rotating rod. By rotating the rotating rod, the turntable and the threaded rod rotate together. Since the threaded sleeve is threadedly connected to the threaded rod, the threaded sleeve will move up and down on the threaded rod.

[0008] Preferably, the drilling structure is equipped with a drilling motor, and a gearbox is installed on the output end of the drilling motor. A drill rod is installed on the output end of the gearbox via an anti-detachment connecting sleeve. A drill bit is fixedly installed at the bottom of the drill rod for drilling the PCB board. The gearbox can adjust the rotation speed of the drill rod to adapt to different drilling needs, improving drilling efficiency and accuracy. The anti-detachment connecting sleeve ensures a stable connection between the drill rod and the gearbox, preventing the drill rod from falling off or loosening during drilling, thus ensuring the smooth progress of the drilling operation.

[0009] Preferably, the bottom of the support rod is provided with an anti-slip pad made of rubber, and the lower surface of the anti-slip pad has anti-slip texture. This design can effectively increase the friction between the support rod and the ground or workbench, preventing the drilling device from sliding or shifting during use, ensuring the stability and accuracy of drilling operations. The rubber anti-slip pad also has a certain degree of elasticity and cushioning, which can reduce the vibration generated by the drilling device during operation, further protecting the PCB board from damage and improving drilling quality.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. The upper surface of the frame of this utility model is equipped with a shock-absorbing base plate. During the drilling process, the drilling structure will generate vibrations, which may be transmitted to the frame, thereby affecting the accuracy and stability of the drilling. The shock-absorbing base plate installed on the upper surface of the frame can effectively absorb and buffer the vibration energy generated during the drilling process, reduce the impact of vibration on the frame and other components, and improve the quality and accuracy of PCB board drilling.

[0012] 2. The sliding groove of this utility model provides a guide and track for the sliding block. Through the constraint of the sliding groove, the sliding block can only move along the side wall of the lifting sliding seat in a set direction, so that the drilling structure installed on the sliding block can be adjusted in the horizontal direction to realize drilling operations at different positions on the PCB board. The drilling structure is installed on the sliding block, and a PLC controller is installed on the front surface of the lifting sliding seat. The sliding block provides the installation position and power transmission for the horizontal movement of the drilling structure. The drilling structure generally includes components such as a motor and a drill bit. The motor drives the drill bit to rotate at high speed to drill holes in the PCB board fixed on the clamping structure. Under the drive of the sliding block, the drilling structure can move in the horizontal direction, and under the drive of the lifting sliding seat, it can move in the vertical direction to realize drilling operations at different positions and depths on the PCB board.

[0017] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0018] like Figure 1-3As shown, this utility model proposes a PCB board drilling device with automatic positioning function, including a frame 1, a lifting sliding seat 4, a clamping structure 6, and a drilling structure 9. Support rods 2 are installed around the bottom perimeter of the frame 1. These support rods 2 support the frame, separating it from the ground or other supporting surfaces to maintain a stable standing posture. The perimeter installation method evenly distributes the overall weight of the device, preventing tipping due to center of gravity shift and ensuring stability during operation, providing a stable foundation for precise drilling. A shock-absorbing base plate 3 is installed on the upper surface of the frame 1. During drilling, the drilling structure... The drilling process generates vibrations, which may be transmitted to the frame 1, affecting the accuracy and stability of the drilling. The vibration-damping base plate 3, installed on the upper surface of the frame 1, effectively absorbs and buffers the vibration energy generated during drilling, reducing the impact of vibration on the frame and other components, and improving the quality and accuracy of PCB board drilling. A clamping structure 6 is installed on the vibration-damping base plate 3, providing a stable mounting foundation for the clamping structure 6 and reducing potential interference from vibration. The clamping structure 6 securely fixes the PCB board to the vibration-damping base plate using mechanical or electromagnetic means, ensuring that the PCB board does not shift due to drilling force or other factors during drilling, thus guaranteeing the drilling position. To ensure accuracy, a lifting slide seat 4 is installed on the upper surface of the frame 1. The lifting slide seat 4, mounted on the upper surface of the frame 1, achieves vertical lifting movement through an internal lifting drive mechanism. This lifting function allows the drilling structure mounted on it to be adjusted to a suitable drilling height according to PCB boards of different thicknesses, meeting the drilling requirements of PCB boards of different specifications. A sliding groove 7 is formed on one side wall of the lifting slide seat 4, and a sliding block 8 is installed on the sliding groove 7. The sliding groove 7 provides a guide and track for the sliding block 8. Constrained by the sliding groove 7, the sliding block 8 can only move along the set direction on the side wall of the lifting slide seat 4, thus ensuring the drilling height of the PCB board mounted on it. The drilling structure on the moving block 8 can be adjusted in the horizontal direction to realize drilling operations at different positions on the PCB board. The drilling structure 9 is installed on the sliding block 8, and the PLC controller 5 is installed on the front surface of the lifting sliding seat 4. The sliding block 8 provides the installation position and power transmission for the horizontal movement of the drilling structure 9. The drilling structure 9 generally includes components such as a motor and a drill bit. The motor drives the drill bit to rotate at high speed to drill holes in the PCB board fixed on the clamping structure 6. Under the drive of the sliding block 8, the drilling structure 9 can move in the horizontal direction, and under the drive of the lifting sliding seat 4, it can move in the vertical direction to realize drilling operations at different positions and depths on the PCB board.

[0019] The clamping structure 6 is internally connected to a threaded rod 604, and a threaded sleeve 603 is threadedly installed around the threaded rod 604. A slide rail 601 is provided inside the clamping structure 6, and a slider 602 is slidably connected to the bottom of the threaded sleeve 603 inside the slide rail 601. A clamping plate 605 is fixedly connected to the bottom of the slider 602. The clamping plate 605 is used to fix the PCB board. By rotating the threaded rod 604 and the threaded sleeve 603, the screws move up and down along the threaded rod 604, thereby causing the slider 602 to slide within the slide rail 601, realizing the lifting and lowering of the clamping plate 605 to accommodate PCB boards of different thicknesses. The top of the threaded sleeve 603 is fixedly connected to the clamping plate 605. A turntable 606 is fixedly connected to one side of the threaded rod 604, and a rotating rod 607 is fixedly connected to one side of the turntable 606. A sponge pad 608 is sleeved around the rotating rod 607. The sponge pad 608 increases the grip comfort of the rotating rod 607 and prevents the hand from slipping when rotating the rotating rod 607. Rotating the rotating rod 607 drives the turntable 606 and the threaded rod 604 to rotate together. Since the threaded sleeve 603 is threadedly connected to the threaded rod 604, the threaded sleeve 603 will move up and down on the threaded rod 604.

[0020] The drilling structure 9 is equipped with a drilling motor 91, and a gearbox 92 is installed on the output end of the drilling motor 91. A drill rod 94 is installed on the output end of the gearbox 92 through an anti-detachment connecting sleeve 93. A drill bit 95 is fixedly installed at the bottom of the drill rod 94 for drilling the PCB board. The gearbox 92 can adjust the rotation speed of the drill rod 94 to adapt to different drilling needs, improve drilling efficiency and accuracy. The anti-detachment connecting sleeve 93 ensures a stable connection between the drill rod 94 and the gearbox 92, preventing the drill rod 94 from falling off or loosening during drilling, thus ensuring smooth drilling operations. The bottom of the support rod 2 is equipped with an anti-slip pad made of rubber, and the lower surface of the anti-slip pad has anti-slip texture. This design effectively increases the friction between the support rod 2 and the ground or workbench, preventing the drilling device from sliding or shifting during use, ensuring the stability and accuracy of drilling operations. The rubber anti-slip pad also has a certain degree of elasticity and cushioning, which can reduce the vibration generated by the drilling device during operation, further protecting the PCB board from damage and improving drilling quality.
