[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0024] Example 1

[0025] Reference Figure 1-3The first embodiment of this utility model provides a drilling device for PCB circuit board processing, including a workbench 1, a U-shaped plate 2 fixedly connected to the top of the workbench 1, a first motor 3 arranged on the inner side of the U-shaped plate 2, a drill bit 4 fixedly installed at the output end of the first motor 3, an adjustment mechanism 5 arranged on the inner side of the U-shaped plate 2, and a pushing mechanism 6 arranged on the top of the workbench 1.

[0026] Specifically, compared to the existing manual drilling method, this device completes drilling through mechanical automation, eliminating the need for intensive human labor. This effectively solves the problem of low efficiency in manual drilling, reduces reliance on manpower, overcomes the production capacity limitations caused by manual operation, and helps to reduce production costs and improve production efficiency.

[0027] Furthermore, the PCB circuit board processing drilling device is based on the worktable 1, with the U-shaped plate 2 as the supporting frame. The first motor 3 drives the drill bit 4 to rotate to realize the drilling action. The adjustment mechanism 5 can adjust the position, height and horizontal direction of the drill bit 4. The pushing mechanism 6 drives the PCB circuit board to move on the worktable 1, so that the drill bit 4 can drill holes in different positions of the circuit board. The whole device achieves automated operation of the drilling process through mechanical structure and motor drive.

[0028] Example 2

[0029] In the second embodiment of this utility model, the adjustment mechanism 5 includes an electric telescopic rod 51, a support plate 52, and a connector 53. The electric telescopic rod 51 is fixedly connected to the top of the U-shaped plate 2, and the output end of the electric telescopic rod 51 extends through to the inner side of the U-shaped plate 2. The connector 53 is fixedly connected to the output end of the electric telescopic rod 51, and the support plate 52 is fixedly connected to the bottom of the connector 53. The electric telescopic rod 51 is movably connected to the bottom of the support plate 52, and a drive assembly 54 is provided on the front side of the support plate 52.

[0030] The drive assembly 54 includes a first L-shaped plate 541, a second motor 542, a first screw 543, a first groove 544, and a first slider 545. The first L-shaped plate 541 is fixedly connected to the front side of the top of the support plate 52. The second motor 542 is fixedly connected to the inner side of the first L-shaped plate 541. The first groove 544 is opened on the top of the support plate 52. The first screw 543 is fixedly connected to the output end of the second motor 542. The first slider 545 is movably connected to the inside of the first groove 544. The first slider 545 is threadedly connected to the first screw 543. The top end of the first motor 542 is fixedly connected to the bottom end of the first slider 545.

[0031] Specifically, the height of the drill bit 4 is automatically adjusted by driving the support plate 52 up and down through the electric telescopic rod 51, eliminating the need for manual adjustment. This is more precise and efficient than manual adjustment, and can flexibly adapt to PCB circuit boards of different thicknesses, expanding the applicability of the device, reducing the intensity of manual operation, and further improving the automation of drilling. The horizontal position of the drill bit 4 is automatically driven through the second motor 542, the first screw 543, and other structures, replacing the manual movement of the drill bit 4 or the circuit board to adjust the drilling position. This improves the accuracy of the drilling position, avoids errors caused by manual operation, speeds up the position adjustment, and improves the overall drilling efficiency.

[0032] Furthermore, in the adjustment mechanism 5, when the electric telescopic rod 51 extends or retracts, its output end drives the support plate 52 to move up and down through the connector 53, thereby driving the first motor 3 and the drill bit 4 at the bottom to adjust the height to meet the drilling requirements of PCB circuit boards of different thicknesses. The drive component 54 on the support plate 52 can drive the first motor 3 and the drill bit 4 to move horizontally. Combined with the height adjustment, the position adjustment of the drill bit 4 in three-dimensional space is realized. When the drive component 54 is working, the second motor 542 starts and drives the first screw 543 to rotate. Since the first slider 545 is threadedly connected to the first screw 543 and is limited by the first slide groove 544, the rotation of the first screw 543 will drive the first slider 545 to slide horizontally along the first slide groove 544, thereby driving the first motor 3 and the drill bit 4 at the bottom to move horizontally synchronously, realizing the precise position adjustment of the drill bit 4 in the lateral direction.

[0033] Example 3

[0034] In the third embodiment of this utility model, the pushing mechanism 6 includes a perforated plate 61, a second slider 62, and a second slide groove 63. The perforated plate 61 is movably connected to the top of the workbench 1, the second slide groove 63 is opened on the top of the workbench 1, the second slider 62 is fixedly connected to the bottom of the perforated plate 61, and the second slider 62 is slidably connected to the second slide groove 63. A fixing component 64 is provided on the top of the perforated plate 61.

[0035] The fixing component 64 includes a second L-shaped plate 641, a spring 642, and a fixing member 643. The second L-shaped plates 641 are fixedly connected to both sides of the top of the perforated plate 61 and are arranged symmetrically. The spring 642 is fixedly connected to the inner side of the second L-shaped plate 641. The fixing member 643 is fixedly connected to the other end of the spring 642, and the bottom of the fixing member 643 is movably connected to the top of the perforated plate 61.

[0036] Specifically, the punch plate 61 achieves smooth movement through the cooperation of the slider and the slide, replacing manual pushing of the circuit board, reducing manual operation, and stably transporting the circuit board to the designated punching position. This avoids punching errors caused by instability during manual pushing, improves the continuity and efficiency of punching, and helps to increase production capacity. The cooperation of the spring 642 and the fixing part 643 achieves automatic clamping and fixing of the PCB circuit board, eliminating the need for manual pressing and fixing, reducing manual operation steps, adapting to circuit boards of different widths, and fixing them firmly. This avoids punching deviations caused by displacement of the circuit board during punching, ensuring punching quality, while also being easy to operate and improving the efficiency of picking up and putting down circuit boards.

[0037] Furthermore, in the pushing mechanism 6, the punching plate 61 is used to place the PCB circuit board. The sliding cooperation between the second slider 62 and the second slide groove 63 provides a moving track for the punching plate 61. When it is necessary to adjust the punching position of the circuit board, the punching plate 61 can slide in the second slide groove 63 through the second slider 62, driving the circuit board to move on the worktable 1, so that the area to be punched moves below the drill bit 4. The fixing component 64 fixes the circuit board to prevent it from shifting during the movement. When the fixing component 64 is working, the PCB circuit board is placed on the punching plate 61. When the springs 642 on the inner side of the second L-shaped plates 641 on both sides are in the natural state, the fixing component 643 moves inward under the elastic force of the spring 642, thereby clamping and fixing the circuit board on the punching plate 61. When it is necessary to pick up or put down the circuit board, the fixing component 643 is pulled outward to compress the spring 642. After releasing, the spring 642 resets and clamps again.

[0038] Working principle:

[0039] In use, the BCD circuit board is placed on top of the punch plate 61. When the springs 642 on the inner side of the second L-shaped plates 641 on both sides are in their natural state, the fixing member 643 moves inward under the elastic force of the spring 642, thereby clamping and fixing the circuit board onto the punch plate 61. The third motor 8 is started to drive the second screw 9 to rotate. Since the second screw 9 is movably connected to the second slider 62, the rotation of the second screw 9 will drive the second slider 62 to slide along the second slide groove 63, thereby driving the punch plate 61 and the PCB circuit board on it to move automatically, realizing the automated drive of the feeding process. When the circuit board moves to the inner side of the U-shaped plate 2, the electric telescopic rod 51 extends and retracts. Its output end drives the support plate 52 to move up and down through the connector 53, thereby driving the first motor 3 at the bottom and the drill bit 4 to adjust the height direction to adapt to the drilling requirements of PCB circuit boards of different thicknesses. The second motor 542 is started and drives the first screw 9 to rotate. When rod 543 rotates, the first slider 545 is threadedly connected to the first screw 543 and limited by the first groove 544. The rotation of the first screw 543 drives the first slider 545 to slide horizontally along the first groove 544, thereby driving the first motor 3 and drill bit 4 at the bottom to move horizontally synchronously, realizing the precise position adjustment of drill bit 4 in the lateral direction. Finally, the first motor 3 drives drill bit 4 to rotate to realize the drilling action, thus achieving the effect of fixing and drilling the PCB circuit board. At the same time, the pin 10 passes through the second L-shaped plate 641, which guides and limits the movement of the fixing part 643, preventing the fixing part 643 from shifting under the elastic force of spring 642. Spring 642 is sleeved on the surface of pin 10 to avoid twisting and deformation when spring 642 extends and retracts, ensuring the stability of spring 642's elastic force. The soft pad 11 at the bottom of fixing part 643 contacts the PCB circuit board, reducing the squeezing damage to the circuit board surface when clamped.

[0040] In summary, this utility model, by setting up a U-shaped plate 2, a first motor 3, and a drill bit 4, uses the U-shaped plate 2 as a supporting frame and the first motor 3 to drive the drill bit 4 to rotate to achieve the drilling action. This solves the problem that the existing PCB circuit board uses manual drilling, which is inefficient and relies on high-intensity manual operation, resulting in limited production capacity and high production costs.
