9. The automated circuit board punching equipment according to claim 8, characterized in that: The clamping block (55) is composed of an inclined block (551) at the lower end and an L-shaped block (552) at the upper end.

10. A punching method, using the automated circuit board punching equipment according to claim 9, characterized in that: The following steps are involved: Step 1: After the circuit board (6) is transferred to the loading platform (2), the double-actuator slide (53) drives the clamping block (55) on the right to push the circuit board (6) to the left until the circuit board (6) is blocked by the positioning pin (52) on the loading platform (2) to complete the calibration and positioning of the circuit board (6); Step 2: The clamping blocks (55) on both sides approach the circuit board (6), and gradually clamp the circuit board (6) from both sides of the circuit board (6). The circuit board (6) first contacts the inclined block (551) of the clamping block (55) and moves upward, so that the circuit board (6) is suspended on the upper side of the support platform. Finally, the circuit board (6) is positioned and clamped by the L-shaped blocks (552) on the left and right sides and the positioning plates (51) on the front and back sides. Step 3: The double-acting slide (53) drives the clamping block (55) to servo-move the circuit board (6) along the length direction of the support platform, and at the same time, the servo linear slide (41) drives the moving frame (42) to servo-move along the width direction of the support platform, so that the hole to be processed of the circuit board (6) moves between the drill rod (443) and the top block (452); Step 4: The high-speed vertical moving components (43) at the upper and lower ends of the moving frame (42) respectively control the vertical moving plate (441) and the vertical moving rod (451) to move synchronously in the vertical direction, so that the top block (452) moves up to support the structure around the hole to be processed of the circuit board (6), and then the drill rod (443) moves down to perform a drilling operation on the circuit board (6), and during the drilling operation, the shield (446) presses against the circuit board (6) from the upper end of the circuit board (6), blows air into the shield (446) and the avoidance chamber (453) through the blowing pipe (46) to exhaust waste chips, and sucks air from the shield (446) and the avoidance chamber (453) through the chip removal pipe (47) to remove the waste chips; Step 5: Repeat steps 3 and 4 until all holes of the circuit board (6) are processed one by one; Step 6: The clamping block (55) moves the processed circuit board (6) to the unloading table (3) and releases it, and then pushes the circuit board (6) to the right through the clamping block (55) on the left until the circuit board (6) is blocked by the positioning pin (52) on the unloading table (3) to complete the calibration positioning of the circuit board (6).
