[0024] A punching mechanism for punching holes in the circuit board is disposed on the bottom plate 1 , and the punching mechanism is located below the limiting groove 16 .

[0025] As a technical optimization solution of the utility model, the punching mechanism includes an electric telescopic rod 10 installed on the top of the base plate 1, and a second motor 11 is installed at the end of the piston rod of the electric telescopic rod 10. The output shaft of the second motor 11 is connected to a drill bit 12, and the drill bit 12 is located below the limiting groove 16. The output shaft of the second motor 11 can easily drive the drill bit 12 to rotate to drill holes in the circuit board.

[0026] As a technical optimization solution of the utility model, a mounting plate 13 is installed at the end of the piston rod of the electric telescopic rod 10, and the second motor 11 is installed on the top of the mounting plate 13. The mounting plate 13 can provide a mounting position for the second motor 11, which is convenient for the second motor 11 to be connected to the piston rod of the electric telescopic rod 10.

[0027] As a technical optimization solution of the utility model, a mounting groove is opened on the top of the base plate 1, and a first motor 4 is installed in the mounting groove. The output shaft of the first motor 4 is connected to the screw rod 5, and the output shaft of the first motor 4 can easily drive the screw rod 5 to rotate.

[0028] As a technical optimization solution of the utility model, a bearing 14 is installed at the bottom of the top plate 3, and the top of the screw rod 5 is installed on the inner ring of the bearing 14. The bearing 14 can provide guidance for the rotation of the screw rod 5 and improve the stability of the screw rod 5 during rotation.

[0029] As a technical optimization solution of the utility model, a layer of rubber pad is arranged on the top of the rectangular limit frame 15.

[0030] As a technical optimization solution of the utility model, a second mounting frame 19 is installed at the bottom of the rectangular limit frame 15, a second sliding sleeve 18 is installed at the end of the second mounting frame 19, a second sliding rod 17 is installed between the bottom plate 1 and the top plate 3, the second sliding sleeve 18 is slidably connected to the second sliding rod 17, and a mounting hole is opened on the bottom plate 1. Through the coordinated use of the second sliding sleeve 18 and the second sliding rod 17, a guide can be provided for the rectangular limit frame 15 when it moves up and down, thereby improving the stability of the rectangular limit frame 15 when it moves up and down.

[0031] When the utility model is in use, when it is necessary to perforate the circuit board, first, start the first motor 4, and the output shaft of the first motor 4 drives the screw rod 5 to rotate. The rotation of the screw rod 5 causes the internal thread block 6 to move downward on the screw rod 5. The downward movement of the internal thread block 6 can drive the first mounting bracket 9 to move downward. The downward movement of the first mounting bracket 9 can drive the rectangular limit frame 15 to move downward until the gap between the rectangular limit frame 15 and the top plate 3 can place the circuit board in the limit groove 16 and then stop.

[0032] The circuit board to be perforated is placed in the limiting groove 16, and the first motor 4 is started again. The output shaft of the first motor 4 drives the screw rod 5 to rotate. The rotation of the screw rod 5 can make the internal thread block 6 move upward on the screw rod 5. The internal thread block 6 can drive the first mounting bracket 9 to move upward when it moves upward, and the first mounting bracket 9 can drive the rectangular limiting frame 15 to move upward until the rubber pad on the top of the rectangular limiting frame 15 comes into contact with the circuit board, and the rectangular limiting frame 15 is used to make an upward movement to abut and fix the circuit board in the limiting groove 16. The circuit board can be fixed in the limiting groove 16 at the bottom of the top plate 3, and the rubber pad on the top of the rectangular limiting frame 15 is used to contact the circuit board to press the circuit board tightly. The softness of the rubber pad can be used to provide a flexible pressing force for the circuit board to avoid deformation and damage of the circuit board due to rigid pressing, thereby improving the protection of the circuit board.

[0033] After the circuit board is fixed in the limiting groove 16, the electric telescopic rod 10 is started, and the second motor 11 is started at the same time. The output shaft of the second motor 11 drives the drill bit 12 to rotate, and the piston rod of the electric telescopic rod 10 pushes the mounting plate 13 to move upward. The upward movement of the mounting plate 13 can drive the second motor 11 and the drill bit 12 to move upward until the top of the drill bit 12 contacts the circuit board. The drill bit 12 can be used to drill holes in the circuit board, and as the piston rod of the electric telescopic rod 10 continues to extend, the drill bit 12 can be used to continuously move upward to drill holes in the circuit board until the circuit board is drilled to a preset depth. The drilling of the circuit board can be completed. The device uses the drill bit 12 to drill holes in the circuit board from bottom to top. Circuit board debris generated by the drill bit 12 when drilling the circuit board can fall downward under the action of its own gravity, and will not fall on the circuit board to cause dirt and damage to the circuit board. When the drill bit 12 is drilling holes in the circuit board, the circuit board debris generated can automatically fall downward.
