[0018] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0019] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.
[0020] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.
[0021] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include the three-dimensional spatial dimensions of length, width, and depth. Example
[0022] Reference Figure 1-5 This is the first embodiment of the present invention, which provides a multi-point drilling device for computer motherboard processing, including a worktable 1, a fixed frame 2 fixedly connected to the top of the worktable 1, an electric telescopic rod 3 fixedly connected to the top of the fixed frame 2, a support plate 4 fixedly connected to the output end of the electric telescopic rod 3, a first sliding groove 5 opened at the bottom of the support plate 4, a first slider 6 slidably connected inside the first sliding groove 5, a U-shaped mounting bracket 7 fixedly connected to the bottom of the first slider 6, a third motor 8 fixedly connected inside the U-shaped mounting bracket 7, a drill bit 9 fixedly connected to the output end of the third motor 8, a processing plate 10 movably connected to the top of the worktable 1, a fixing mechanism 11 provided on the top of the processing plate 10, and a drive adjustment component 12 provided inside the first sliding groove 5.
[0023] Specifically, the structure integrates multiple automated functions such as horizontal electric adjustment of drill bit 9, movement adjustment of processing plate 10, and electric lifting of drill bit 9, completely replacing manual drive, reducing the labor intensity of operators, and eliminating the need for frequent manual adjustment of the main board or drill bit 9 position when drilling multiple points.
[0024] Furthermore, this multi-point drilling device uses the workbench 1 as the basic supporting component, and the top fixing frame 2 provides a support frame for the drilling mechanism. The electric telescopic rod 3 at the top of the fixing frame 2 drives the support plate 4 and the bottom drilling assembly to move up and down, realizing the feed and reset of the drill bit 9. The first slide groove 5 at the bottom of the support plate 4 slides in cooperation with the first slider 6. The U-shaped mounting bracket 7 at the bottom of the first slider 6 carries the third motor 8 and the drill bit 9. The drive adjustment component 12 in the first slide groove 5 can drive the first slider 6 to slide laterally, thereby adjusting the lateral drilling position of the drill bit 9. The processing plate 10 on the top of the worktable 1 is used to place the computer motherboard. The fixing mechanism 11 on the top clamps and fixes the motherboard. The processing plate 10 can move relative to the worktable 1. In conjunction with the lateral movement of the drill bit 9, multi-point drilling can be achieved at different positions on the motherboard. During operation, the motherboard is fixed on the processing plate 10. The relative position of the drill bit 9 and the motherboard is adjusted in coordination with the moving mechanism of the processing plate 10 through the drive adjustment component 12. The electric telescopic rod 3 drives the drill bit 9 to descend and drill. After completing one hole, the position is adjusted to continue processing the next hole, realizing multi-point automated drilling. Example
[0025] In the second embodiment of the present invention, the fixing mechanism 11 includes a third slide groove 111, a third slider 112, and an L-shaped fixing member 113. The third slide groove 111 is opened on both sides of the top of the processing plate 10. The L-shaped fixing member 113 is movably connected to both sides of the top of the processing plate 10. The third slider 112 is fixedly connected to the bottom of the L-shaped fixing member 113. The third slider 112 is slidably connected to the third slide groove 111. The third slide groove 111 is provided with a spring-loaded component 114.
[0026] The rebound assembly 114 includes a slide rod 1141 and a spring 1142. The slide rod 1141 is fixedly connected inside the third slide groove 111. The third slider 112 is sleeved on the surface of the slide rod 1141. The spring 1142 is fixedly connected inside the third slide groove 111 on the side away from the third slider 112. The other end of the spring 1142 is fixedly connected to the outside of the third slider 112.
[0027] Specifically, this mechanism achieves automatic elastic clamping of the computer motherboard, replacing manual pressing and fixing, further reducing the labor intensity of operators. The elastic clamping force is adapted to motherboards of different thicknesses, avoiding damage to the motherboard circuit layer caused by rigid clamping. The third slider 112 cooperates with the third slide groove 111 to adapt to motherboards of different widths, eliminating the need to change fixing components according to motherboard size, making operation convenient. This component provides a stable elastic clamping force to ensure the clamping stability of the L-shaped fixing member 113 on the motherboard, preventing the motherboard from loosening and shifting during drilling, ensuring drilling accuracy. The guiding effect of the slide rod 1141 makes the movement and clamping process of the L-shaped fixing member 113 smooth and without jamming, avoiding uneven local force on the motherboard due to clamping deviation. The spring 1142 has stable elastic recovery and a long service life, adapting to the long-term, high-frequency motherboard fixing needs, reducing component maintenance costs. At the same time, the elastic characteristics can adapt to slight irregularities on the edge of the motherboard, improving clamping adaptability.
[0028] Furthermore, the fixing mechanism 11 uses the third slide grooves 111 on both sides of the top of the processing plate 10 as a guide. When placing the computer motherboard, the L-shaped fixing members 113 are pulled to both sides, causing the third slider 112 to move outward along the third slide groove 111 and compress the springback assembly 114. After the motherboard is placed at the center of the top of the processing plate 10, the L-shaped fixing members 113 are released. The elastic restoring force of the springback assembly 114 pushes the third slider 112 to move the L-shaped fixing members 113 inward. The motherboard is fixed by the relative clamping force of the L-shaped fixing members 113 on both sides, restricting the motherboard from moving laterally during the drilling process. When the L-shaped fixing member 113 is pulled, the spring-loaded component 114 uses the slide rod 1141 inside the third slide groove 111 as a guide component. When the L-shaped fixing member 113 is pulled, the third slider 112 moves outward along the slide rod 1141 and compresses the spring 1142, so that the spring 1142 stores elastic potential energy. After the L-shaped fixing member 113 is released, the elastic restoring force of the spring 1142 pushes the third slider 112 to reset inward along the slide rod 1141, causing the L-shaped fixing member 113 to clamp the main board. The slide rod 1141 restricts the positioning of the third slider 112 to move only in the lateral direction, avoiding clamping offset caused by the twisting of the spring 1142. Example
[0029] In the third embodiment of the present invention, the drive adjustment assembly 12 includes a first support block 121, a first motor 122 and a first screw 123. The first support block 121 is fixedly connected to the top of the left side of the support plate 4, the first motor 122 is fixedly connected to the inner side of the first support block 121, the first screw 123 is fixedly connected to the output end of the first motor 122, and the first slider 6 is threadedly connected to the first screw 123.
[0030] Specifically, this component enables automated and precise adjustment of the lateral position of drill bit 9, replacing manual pushing and adjustment, improving adjustment efficiency and movement accuracy, ensuring accurate drilling position, avoiding motherboard scrapping caused by hole position deviation, and improving product quality. The first motor 122 provides stable driving power and can smoothly drive the drilling component to move, improving operational stability. The first motor 122 has a built-in braking function, which can lock the position of drill bit 9 during drilling to prevent drill bit 9 from shifting during drilling, further ensuring drilling accuracy.
[0031] Furthermore, the drive adjustment assembly 12 uses the first support block 121 on the top left side of the support plate 4 as the mounting carrier for the first motor 122. The first motor 122 is the power source, and its output end has a first screw 123 threadedly connected to the first slider 6. When the first motor 122 is started, the rotation of the first screw 123 converts the rotational motion into the linear motion of the first slider 6, driving the first slider 6 to drive the U-shaped mounting bracket 7, the third motor 8, and the drill bit 9 to slide laterally along the first slide groove 5, thereby achieving precise adjustment of the lateral drilling position of the drill bit 9. The forward and reverse rotation of the first motor 122 can control the movement direction of the first slider 6. By controlling the running time of the first motor 122, the movement distance of the drill bit 9 can be precisely controlled to ensure that the drill bit 9 is accurately aligned with the target hole position.
[0032] In use, the workbench 1 serves as the basic supporting component, and the top mounting bracket 2 provides a support frame for the drilling mechanism. The electric telescopic rod 3 at the top of the mounting bracket 2 drives the support plate 4 and the bottom drilling assembly to move up and down, thereby enabling the drill bit 9 to feed and reset. When the first motor 122 inside the first support block 121 is activated, the first screw 123 rotates, converting the rotational motion into the linear motion of the first slider 6. This drives the first slider 6 to move the U-shaped mounting bracket 7, the third motor 8, and the drill bit 9 laterally along the first slide groove 5, achieving precise adjustment of the drill bit 9's lateral drilling position. When placing the computer motherboard, the L-shaped fixing piece 1 is pulled to both sides. 13. The third slider 112 moves outward along the slide rod 1141 and compresses the spring 1142, allowing the spring 1142 to store elastic potential energy. After the main board is placed at the top center of the processing plate 10, the L-shaped fixing member 113 is released. The elastic restoring force of the spring 1142 pushes the third slider 112 back inward along the slide rod 1141, causing the L-shaped fixing member 113 to clamp the diagonally opposite sides of the main board. The slide rod 1141 restricts the positioning of the third slider 112 to move only laterally, avoiding clamping offset caused by the twisting of the spring 1142. After adjusting the relative position of the drill bit 9 and the main board, the third motor 8 is started to drive the drill bit. Rotating the electric telescopic rod 3 drives the drill bit 9 to descend and drill holes. After completing one hole, the position is adjusted to continue processing the next hole, achieving multi-point automated drilling. This achieves the flexible drilling effect required for computer motherboard processing. Graphite chips and metal scrap generated during drilling fall into the third chute 111 through the recovery hole 19, and then slide into the collection box 20 through the connecting channel between the third chute 111 and the collection trough 18 for centralized collection. When the collection box 20 is full, it can be pulled out of the collection trough 18 using the handle on the back to complete the waste removal. After cleaning, the collection box 20 is reset to continue the process. During the recovery operation, when the main board needs to be moved laterally for processing, the second motor 16 inside the second support block 15 is activated, and the second screw 17 rotates, converting the rotational motion into the linear motion of the second slider 14. This drives the second slider 14 to move the processing plate 10 longitudinally along the second slide groove 13, thereby adjusting the longitudinal position of the main board. At the same time, when the electric telescopic rod 3 drives the support plate 4 to move the drill bit 9 up and down for feeding, the limit rod 21 slides synchronously along the through hole of the fixed frame 2, restricting the support plate 4 to move only vertically. This prevents the support plate 4 from tilting or shifting due to uneven force or vibration, ensuring that the drill bit 9 always maintains a vertical feeding state.
[0033] In summary, this invention, by setting up a fixed frame 2, an electric telescopic rod 3, a support plate 4, a first sliding groove 5, a first slider 6, a U-shaped mounting frame 7, a third motor 8, a drill bit 9, and a processing plate 10, allows the electric telescopic rod 3 to drive the support plate 4 and the drilling assembly at the bottom to move up and down, thereby enabling the drill bit 9 to feed and reset. The first sliding groove 5 at the bottom of the support plate 4 and the first slider 6 slide together to form a lateral adjustment of the drill bit 9. This solves the problem that current multi-point drilling devices lack electric movement functions and rely entirely on manual driving and positioning, resulting in high labor intensity for operators and limited overall processing efficiency.
