[0023] The fixed part of the electric push rod 8 is installed on the bottom wall of the supporting sleeve 1 by bolts, the output end of the electric push rod 8 is connected to the lifting plate 10 by screws, the lifting plate 10 is slidingly connected to the supporting sleeve 1, and the electric push rod 8 can adjust the height of the clamping frame 5 through the lifting plate 10, thereby facilitating docking with drilling equipment at different heights.

[0024] The motor 9 is installed on the lifting plate 10 by bolts, and the output shaft of the motor 9 is fixedly connected to the rotating cover 7. The motor 9 can drive the clamping mechanism to rotate through the rotating cover 7, and then the clamped aluminum nitride substrate is sequentially transported to the drill rod, so as to realize continuous feeding.

[0025] The cylinder 4 is connected to the clamping frame 5 by screws, and the output end of the cylinder 4 is connected to the clamping plate 3 by screws. The cylinder 4 pushes the clamping plate 3 to clamp and fix the aluminum nitride substrate.

[0026] A collecting drawer 2 is installed at the bottom end of the clamping frame 5. The collecting drawer 2 is slidably connected to the clamping frame 5. The collecting drawer 2 can collect waste generated during the punching process.

[0027] Two groups of slide grooves 11 are provided on the inner bottom wall of the clamping frame 5, and two groups of sliders 12 are fixed at the positions corresponding to the slide grooves 11 at the bottom of the collecting drawer 2. The sliders 12 are slidably connected to the slide grooves 11. Both the sliders 12 and the slide grooves 11 are T-shaped structures.
