[0020] The electric slide rail 13 drives the installation frame 5 to move, and the installation frame 5 can be moved up and down by the extension of the telescopic rod 14. The motor 6 drives the cutting knife 7 to rotate, so as to cut the heat sink. The extension of the telescopic rod 29 can drive the limit bar 10 to move, and the two limit bars 10 can limit the moving position of the heat sink plate to prevent the heat sink plate from deviating. A protective cover can be set on the outside of the cutting knife 7 to prevent the debris generated during cutting from splashing around. The protective cover is a prior art, and its specific structure and installation are not described here.

[0021] An installation groove is provided on the top surface of the operating table 1 in the middle of the limit assembly, an electric slide rail 11 is installed inside the installation groove, a vacuum suction cup 12 is installed at the output end of the electric slide rail 11, and the top surface of the vacuum suction cup 12 is flush with the table surface of the operating table 1.

[0022] The vacuum suction cup 12 is connected to the vacuum generator. When the vacuum suction cup 12 is working, it can adsorb the heat sink plate. The electric slide rail 11 drives the heat sink plate to move through the vacuum suction cup 12, so that the heat sink plate can be automatically fed.

[0023] A mounting frame 13 is fixedly connected between the cutting assembly and the limiting assembly on the top of the operating table 1, and a telescopic rod 3 14 is mounted on the mounting frame 13. A pressing plate 15 is mounted on the movable end of the telescopic rod 3 14, and the telescopic rod 3 14 is a hydraulic telescopic rod.

[0024] The extension of the telescopic rod 3 14 causes the position of the pressing plate 15 to drop, and the pressing plate 15 is used to press and fix the heat sink plate, effectively preventing the heat sink plate from vibrating during cutting, thereby improving the cutting quality.
