DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] like Figure 1-Figure 5 As shown, a PCB mechanical blind hole plate manufacturing device comprises a base plate 1, a mounting plate 2 is arranged inside the base plate 1, and a moving mechanism is arranged between the mounting plate 2 and the base plate 1;

[0029] The moving mechanism includes an adjusting screw 16 and two nuts 17. The two nuts 17 are respectively arranged on the two side walls of the bottom plate 1. The adjusting screw 16 is rotatably connected in the two nuts 17. The mounting plate 2 is arranged on the adjusting screw 16. A linear bearing is connected between the mounting plate 2 and the adjusting screw 16. When the adjusting screw 16 rotates, the linear bearing slides along the axial direction of the adjusting screw 16, so that the mounting plate 2 on the linear bearing moves linearly.

[0030] A bottom pad is provided at the bottom of the mounting plate 2, and a limiting mechanism is provided inside the mounting plate 2. The limiting mechanism includes two limiting plates 20. Both limiting plates 20 are provided inside the mounting plate 2, and a double-headed screw 19 is connected between the two limiting plates 20.

[0031] A bracket 3 is connected to one side of the bottom plate 1, a fan 4 is connected to the bracket 3, and an adjustment mechanism is provided at one end of the bracket 3 away from the bottom plate 1;

[0032] The adjusting mechanism comprises a rotating motor 5 and a circular plate 6, wherein the rotating motor 5 is connected to one end of the bracket 3 away from the bottom plate 1, the circular plate 6 is connected to the rotating end of the rotating motor 5, a connecting block 7 is connected to the circular plate 6, an end of the connecting block 7 away from the circular plate 6 is connected to an L-shaped rod 8, an end of the L-shaped rod 8 away from the connecting block 7 is connected to a rotating joint 9, a connecting shaft 12 is inserted into the rotating joint 9, one end of the connecting shaft 12 is connected to a drill rod 13, one end of the drill rod 13 away from the connecting shaft 12 is connected to a connecting interface 14, one end of the connecting interface 14 away from the drill rod 13 is connected to a driving mechanism, one end of the driving mechanism away from the connecting interface 14 is connected to a drill bit 15, and the drill bit 15 is made of cobalt steel alloy;

[0033] A slide plate 11 is provided at one end of the connecting shaft 12 away from the punching mechanism, and a guide rail 18 is provided on the slide plate 11. A ball bearing 21 is connected inside the guide rail 18. The connecting shaft 12 is connected to the ball bearing 21. A coupling 10 is connected between the slide plate 11 and the circular plate 6. When the circular plate 6 rotates, the coupling 10 can keep the connection position between the slide plate 11 and the circular plate 6 unchanged.

[0034] Working principle of the utility model: When using the device, the PCB board is placed between the two limit plates 20 inside the mounting plate 2. The bottom pad arranged at the bottom of the mounting plate 2 can protect the back of the processed material from damage. During the drilling process, the drill bit 15 may leave burrs or produce "burst edge" on the back of the material when penetrating the material. The bottom pad can reduce the occurrence of this situation.

[0035] By adjusting the double-headed screw 19, the two limit plates 20 limit the PCB board, and then the circular plate 6 is driven to rotate by the rotating motor 5, and the circular plate 6 drives the connecting block 7 to rotate, and at the same time the connecting block 7 drives the rotating joint 9 on the L-shaped rod 8 to rotate, and the rotating joint 9 drives the connecting shaft 12 to move up and down, and the connecting shaft 12 drives the ball bearing 21 to move up and down in the guide rail 18, and the height of the drill rod 13 is adjusted until the height of the drill rod 13 is aligned with the position where the PCB board inside the mounting plate 2 needs to be punched. When the position of the PCB board needs to be adjusted left and right, the adjusting screw 16 can be rotated to adjust the position of the mounting plate 2. Adjusting the position of the PCB board can ensure that the position of the drill hole is completely aligned with the design drawing, thereby ensuring the accuracy of the component mounting hole and the conductive hole. When the driving mechanism drives the drill bit 15 to punch the PCB board, the fan 4 can help cool the tool and the workpiece to reduce the risk of material deformation or damage caused by high temperature. Chips and debris will be generated during the drilling process. The airflow of the fan 4 can help blow away these chips to prevent the chips from being embedded in the workpiece or tool and affecting the punching quality and accuracy.
