[0002] PCB, or Printed Circuit Board, is an important electronic component. It serves as the support for electronic components and the carrier for their electrical interconnection. Because it is manufactured using electronic printing technology, it is called a "printed" circuit board.
[0003] To facilitate the installation of PCB boards, holes need to be drilled at specific locations during the PCB board production process. The current method is to use a drilling machine to drill these holes. During the drilling process, workers need to manually load and unload the materials, which is not only labor-intensive but also inefficient. Utility Model Content
[0004] The purpose of this utility model is to provide a drilling device with a simple structure and reasonable design that can automatically load and unload materials in order to solve the above problems.
[0005] This utility model achieves the above objectives through the following technical solutions:
[0006] An automatic loading and unloading drilling device includes a drilling table, a support structure mounted on the drilling table, a drive device mounted on the support structure, a movable plate fixedly connected to the output end of the drive device, a drilling machine mounted on the movable plate, a limiting mold fixedly connected to the drilling table below the movable plate, the top wall of the limiting mold being recessed inward to form a groove, a loading guide box fixedly connected to the other end of the drilling table, the opening end of the loading guide box being fitted with the output end of an external conveyor belt, a servo motor mounted on the bottom wall of the drilling table between the limiting mold and the loading guide box, the output end of the servo motor passing through the drilling table and rotatably connected to the drilling table, an electric telescopic rod mounted on the output end of the servo motor, a rotating plate mounted on the top end of the electric telescopic rod, and an electric suction cup mounted on the end of the rotating plate away from the electric telescopic rod.

[0008] As a further optimization of this utility model, the driving device includes a cylinder installed on the top horizontal section of the bracket, a piston rod installed on the output end of the cylinder, the bottom end of the piston rod passing through the bracket and slidably connected to the bracket, and the movable plate installed on the bottom end of the piston rod.
[0009] As a further optimization of this utility model, both ends of the movable plate are integrally formed with guide plates, and the end of the guide plate away from the movable plate extends into the slide groove. The end of the guide plate is slidably connected to the vertical section of the bracket through the slide groove.
[0010] As a further optimization of this utility model, the size and shape of the inner cavity of the groove provided on the top of the limiting mold are set according to the PCB board model to be drilled, and a through hole is provided on the bottom wall of the groove, the inner diameter of the through hole being larger than the diameter of the drill bit of the drilling machine.
[0011] As a further optimization of this utility model, a baffle is provided on the side wall of the opening end of the feeding guide box.

[0014] 1. Through the coordinated design of servo motors, electric telescopic rods, rotating plates, electric suction cups, and controllers, the controller controls the servo motor to drive the rotating plate to adjust the position of the PCB board adsorbed by the bottom of the electric suction cup. In conjunction with the extension and retraction of the electric telescopic rod and the start and stop of the electric suction cup, the PCB board conveyed to the loading guide box is automatically transported to the groove for drilling, and the drilled PCB board is removed for unloading. This minimizes the problem of manual loading and unloading required by existing drilling equipment, which is not only labor-intensive but also inefficient.

[0021] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.
[0022] Example
[0023] like Figure 1 - Figure 4 As shown, an automatic loading and unloading drilling device includes a drilling platform 1. The bottom of the drilling platform 1 is provided with support legs to support the drilling platform 1 to a suitable height. A bracket 2 is provided on the upper surface of one end of the drilling platform 1. The bracket 2 has a U-shaped structure. The bottom end of the bracket 2 is fixed to the upper surface of the drilling platform 1. A cylinder 3 is installed on the top horizontal section of the bracket 2. A piston rod 4 is installed on the output end of the cylinder 3. The bottom end of the piston rod 4 passes through the bracket 2 and is slidably connected to the bracket 2. A movable plate 5 is fixedly connected to the bottom end of the piston rod 4. When the cylinder 3 is activated, the piston rod 4 can be pushed to extend and retract through the cylinder 3, thereby driving the movable plate 5 to move up and down.
[0024] A drilling machine 8 is installed on the movable plate 5. The installation position of the drilling machine 8 is set according to the position of the PCB board to be drilled. Guide plates 7 are integrally formed at both ends of the movable plate 5. A sliding groove 6 is opened on the inner side wall of the vertical section of the bracket 2. The end of the guide plate 7 away from the movable plate 5 extends into the sliding groove 6. The end of the guide plate 7 is slidably connected to the vertical section of the bracket 2 through the sliding groove 6. It is used to guide the movement path of the drilling machine 8 through the guide plate 7 and the sliding groove 6, so as to avoid the drilling machine 8 from deviating when it moves up and down with the movable plate 5, which would affect the drilling accuracy.
[0025] A limiting mold 9 is fixedly connected to the drilling table 1 below the movable plate 5. The top wall of the limiting mold 9 is recessed inward to form a groove 10. The size and shape of the inner cavity of the groove 10 are set according to the PCB board model to be drilled, so as to facilitate the limiting of the PCB board through the groove 10. A through hole 11 is opened on the bottom wall of the groove 10. The through hole 11 is aligned with the drilling machine 8. The inner diameter of the through hole 11 is larger than the diameter of the drill bit of the drilling machine 8. When the drill bit of the drilling machine 8 drills through the PCB board, it can extend into the through hole 11, so as to avoid damage to the limiting mold 9 caused by the high-speed rotation of the drill bit.
[0026] The other end of the drilling table 1 is fixedly connected to the feeding guide box 12. The open end of the feeding guide box 12 is in contact with the output end of the external conveyor belt. When the PCB board that needs to be drilled is transported to the feeding guide box 12 by the external conveyor belt, the PCB board can be guided by the feeding guide box 12 and the position of the PCB board can be adjusted.
[0027] A servo motor 14 is installed on the bottom wall of the drilling platform 1 between the limiting mold 9 and the feeding guide box 12. The output end of the servo motor 14 passes through the drilling platform 1 and is rotatably connected to the drilling platform 1. An electric telescopic rod 15 is installed on the output end of the servo motor 14. A rotating plate 16 is installed on the top end of the electric telescopic rod 15. An electric suction cup 17 is installed on the end of the rotating plate 16 away from the electric telescopic rod 15. When in use, the servo motor 14 can be started to drive the rotating plate 16 to rotate, rotating the electric suction cup 17 above the feeding guide box 12. Then, the electric telescopic rod 15 can be controlled to retract, driving the rotating plate 16 to retract. The electric suction cup 17 on the 6 moves down until the bottom of the electric suction cup 17 is in contact with the PCB board conveyed to the loading guide box 12. At this time, the electric suction cup 17 is activated and the PCB board is adsorbed to the bottom of the electric suction cup 17 by negative pressure. Then the electric telescopic rod 15 extends and resets, and the servo motor 14 drives the rotating plate 16 to rotate 180 degrees, rotating the electric suction cup 17 to above the limiting mold 9. At this time, the electric telescopic rod 15 retracts again, driving the electric suction cup 17 to move down and put the PCB board into the limiting mold 9. The drilling machine 8 can then perform drilling on the PCB board.
[0028] A baffle 13 is provided on the side wall of the opening end of the feeding guide box 12. The baffle 13 is fixed to the side wall of the feeding guide box 12. The distance between the lower surface of the baffle 13 and the bottom wall of the inner cavity of the feeding guide box 12 is set according to the thickness of the PCB board to be drilled. The baffle 13 is set to limit the PCB board that is attached to the electric suction cup 17, so as to avoid the problem that the electric suction cup 17 will cause the PCB board attached to it to move when it moves the PCB board upward, which will affect the subsequent drilling of the PCB board for accurate placement.
[0029] A controller 18 is installed on one outer wall of the bracket 2. The cylinder 3, drilling machine 8, servo motor 14, electric telescopic rod 15 and electric suction cup 17 are all electrically connected to the controller 18. The controller 18 is a programmable controller. Users can set control programs to control the cylinder 3, drilling machine 8, servo motor 14, electric telescopic rod 15 and electric suction cup 17 to work, forming an assembly line, which greatly improves the drilling efficiency of PCB boards.
[0030] It should be noted that this automatic loading and unloading drilling device is installed at the output end of an external conveyor belt, with the opening of the loading guide box 12 aligned with the output end of the external conveyor belt. When the PCB board to be drilled is conveyed to the loading guide box 12 by the conveyor belt, the loading guide box 12 guides the PCB board and adjusts its position. After the PCB board enters the loading guide box 12, the controller 18 controls the servo motor 14 to drive the rotating plate 16 to rotate, rotating the electric suction cup 17 above the loading guide box 12. Then, the controller 18 controls the electric telescopic rod 15 to retract, causing the electric suction cup 17 mounted on the rotating plate 16 to move downwards until the bottom of the electric suction cup 17 is in contact with the PCB board conveyed into the loading guide box 12. At this time, the electric suction cup 17 is activated, using negative pressure to adsorb the PCB board onto the bottom of the electric suction cup 17. Then, the electric telescopic rod 15 retracts, moving the electric suction cup 17 downwards until the bottom of the electric suction cup 17 is in contact with the PCB board. The rod 15 extends and resets, and the servo motor 14 drives the rotating plate 16 to rotate 180 degrees, rotating the electric suction cup 17 above the limiting mold 9. After rotating to the correct position, the electric telescopic rod 15 retracts again, driving the electric suction cup 17 to move down and place the PCB board into the limiting mold 9. The PCB board is positioned by the groove 10. After positioning, the controller 18 controls the cylinder 3 to push the piston rod 4 to extend, driving the drilling machine 8 mounted on the movable plate 5 to move down and drill. After drilling is completed, the electric telescopic rod 15 extends again, and the servo motor 14 drives the rotating plate 16 to rotate 90 degrees, moving the drilled PCB board to the external collection device placed on one side of the drilling table 1. After rotating to the correct position, the controller 18 controls the electric suction cup 17 to close, allowing the PCB board to fall into the external collection device under its own gravity for collection, thereby realizing automatic loading and unloading of PCB boards.
[0031] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
