[0016] Next, through embodiments and in combination with the drawings, the technical solutions of the present invention will be further specifically described.

[0017] A circuit board processing punching machine includes a machine table 1, and a machine frame 2 is provided above the machine table 1. A hydraulic rod I 3 for fixing the stamping module 5 is provided on the machine frame 2:

[0018] A rectangular groove 6 is provided on the top end face of the machine table 1. A blanking port 7 is provided in the middle of the bottom of the rectangular groove 6. A support base 8 driven by a hydraulic rod II 9 is provided in the blanking port 7. An aggregate box 10 is provided in the machine table 1 on one side of the bottom of the support base 8, and a push plate 12 driven by an electric push rod 11 is provided in the machine table 1 on the other side of the bottom of the support base 8;

[0019] On the top surface of the machine table 1 outside the rectangular groove 6, multiple sets of receiving grooves 13 are provided. A bolt 14 extending into the opening of the rectangular groove 6 is arranged in the receiving groove 13. A rectangular frame 15 for fixing the circuit board is arranged in the rectangular groove 6. A card slot 16 for receiving the end of the rod body of the bolt 14 is arranged in a circular shape on the outer side wall of the rectangular frame 15. A circular air extraction channel 17 is arranged in a circular shape in the top wall of the machine table 1 between the material falling port 7 and the rectangular frame 15. The air extraction channel 17 is connected to a vacuum pump through a pipeline. Multiple groups of air suction holes 18 communicating with the air extraction channel 17 are uniformly arranged on the bottom wall of the rectangular groove 6, and the air suction holes 18 are uniformly arranged on the bottom wall of the rectangular groove 6 between the material falling port 7 and the rectangular frame 15.

[0020] A base 19 for supporting the electric push rod 11 and the push plate 12 is arranged in the machine table 1. The push plate 12, the electric push rod 11 and the base 19 are all arranged in the machine table 1 outside the material falling port 7. The push plate 12 is located above the aggregate box 10. The distance between the bottom end of the push plate 12 and the top end of the aggregate box 10 is not less than the thickness of the support seat 8. One end of the support seat 8 extends to directly above the opening of the aggregate box 10.

[0021] In this embodiment, the top end of the support seat 8 and the bottom end surface of the rectangular groove 6 are on the same horizontal plane, and the size of the support seat 8 is adapted to the size of the material falling port 7.

[0022] As Figure 1 shown, an installation plate 4 is arranged at the bottom end of the output shaft of the hydraulic rod I3. The stamping module 5 is fixed on the bottom end surface of the installation plate 4 through screws, and the stamping module 5 is located directly above the opening of the material falling port 7. Pulley groups 20 are arranged on the corresponding two end surfaces of the installation plate 4. A vertical rod 21 corresponding to the pulley groups 20 is arranged vertically between the frame 2 and the machine table 1, and the pulley grooves in the pulley groups 20 are buckled on the corresponding vertical rods 21.

[0023] In this embodiment, a screw hole for the rod body of the bolt 14 to pass through is arranged in the top wall of the machine table 1 between the receiving groove 13 and the rectangular groove 6, and the rod body of the bolt 14 is screwed with the screw hole.

[0024] The using method of the present invention: Select the corresponding rectangular frame 15 and stamping module 5 according to the size specification of the processed circuit board. The inner diameter of the opening of the rectangular frame 15 is adapted to the size of the circuit board. Then place the rectangular frame 15 in the rectangular groove 6 and rotate the bolt 14 so that it rotates in the screw hole and is embedded in the card slot 16 on the outer side wall of the rectangular frame 15 at the same time;

[0025] The circuit board is placed in the rectangular groove 6 in the opening of the rectangular frame 15 to limit and fix it. At the same time, the vacuum pump evacuates the air extraction channel 17 and the air suction holes 18, so as to adsorb and fix the circuit board in the rectangular groove 6 to prevent it from sliding out of the rectangular groove 6 under the influence of external force;

[0026] Then, the hydraulic rod I3 drives the mounting plate 4 to drive the stamping module 5 to move downward to perform stamping work on the circuit board located above the support seat 8. When the mounting plate 4 moves up and down, it will drive the roller group 20 to slide on the vertical rod 21 to prevent the mounting plate 4 from swinging when moving up and down. When the stamping module 5 resets upward, since the circuit board is adsorbed and fixed at the bottom of the rectangular groove 6, it will not be lifted. At the same time, the hydraulic rod II9 drives the support seat 8 to move downward and slide out from the blanking port 7, so that the support seat 8 moves above the aggregate box 10 and the support seat 8 moves below the top end of the base 19. Then, at this time, the electric push rod 11 drives the push plate 12 to move leftward and slide onto the top surface of the support seat 8, and then pushes the stamping scraps above the support seat 8 into the aggregate box 10 for collection. At the same time, after deflating the air extraction channel 17, the circuit board in the rectangular groove 6 can be taken out.

[0027] The above has described the present invention in detail, but the above content is only the preferred embodiment of the present invention and cannot be considered as defining the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the present invention application shall still fall within the scope covered by the patent of the present invention.
