Compared with traditional heat dissipation materials, graphene has fast thermal conductivity and fast heat dissipation characteristics, which will make graphene an excellent heat dissipation material.

After the cutting is completed, the valve on the exhaust pipe is opened to allow the air from the external environment to enter the cavity 35, so that the staff can remove the cut heat dissipation film.

The cutting mechanism 4 comprises a first support frame 41, a slider 42, a drive motor 43 and a pushing assembly 45. The first support frame 41 is installed on the top surface of the base 1, and the first support frame 41 is in an inverted "L" shape.

A vertical cutting blade 431 is coaxially fixedly connected to the output end of the drive motor 43. The pushing assembly 45 is arranged on the side wall of the first support frame 41, and the push rod assembly can push the slider 42 to move along the length direction of the blade groove 31.

[0040] When cutting the heat dissipation film, start the drive motor 43 to drive the cutting blade 431 to rotate, and the first electric push rod 44 drives the drive motor 43 to gradually move down close to the cutting table 3, so that the bottom of the cutting blade 431 enters the blade groove 31, and then the slider 42 is pushed to move by the pushing component 45. During the movement of the slider 42, the drive motor 43 is driven to move, thereby prompting the cutting blade 431 to cut the heat dissipation film along the length direction of the blade groove 31.

The pushing assembly 45 includes a first motor 451 and a first screw rod 452. The first motor 451 is installed on the side wall of the first support frame 41, and the first screw rod 452 is coaxially fixed to the output end of the first motor 451. The end of the first screw rod 452 away from the first motor 451 extends into the through slot 411 and horizontally penetrates the slider 42.

[0043] like Figure 1 and Figure 5As shown, the top surface of the base 1 is provided with a first slide groove 11 located on the side of the cutting table 3 away from the second slide groove 14. The first slide groove 11 is arranged along the length of the heat dissipation film and along the length direction of the heat dissipation film. The longitudinal cross-section of the first slide groove 11 is dovetail-shaped, and the bottom end of the first support frame 41 is slidably connected to the inner wall of the first slide groove 11. The bottom end of the first support frame 41 is dovetail-shaped and cooperates with the inner wall of the first slide groove 11. A second motor 12 is installed on the outer wall of the base 1, and a second screw rod 13 extending into the first slide groove 11 is coaxially fixed at the output end of the second motor 12.

After the pressure plate 34 presses the end of the heat dissipation film, the second electric push rod 61 is started to drive the concave frame 63 to move down to make the pressure roller 62 contact with the surface of the heat dissipation film, and then the third motor 15 is started to drive the third screw rod 16 to rotate, so as to make the second support frame 5 move along the length direction of the second slide groove 14. During the movement of the second support frame 5, the pressure roller 62 rolls the heat dissipation film to keep the heat dissipation film flat on the cutting table 3, thereby reducing the possibility of bulging of the heat dissipation film laid on the cutting table 3.

[0046] After rolling the heat dissipation film, the vacuum pump 7 is started to evacuate air, so that negative pressure is generated at the air inlet 36, so that the heat dissipation film laid on the cutting table 3 is adsorbed on the cutting table 3 and remains stable. Then, the drive motor 43 is started to drive the cutting blade 431 to rotate, and the first electric push rod 44 is started to drive the drive motor 43 and the cutting blade 431 to gradually move downward, so that the bottom of the cutting blade 431 extends into the blade slot 31, and then the first motor 451 is started to drive the first screw rod 452 to rotate, so that the slider 42 drives the drive motor 43 to move, so that the cutting blade 431 moves along the length direction of the blade slot 31 to cut the heat dissipation film;

[0047] When it is necessary to cut the heat dissipation film of different lengths, the second motor 12 can be started to drive the second screw 13 to rotate, so that the first support frame 41 drives the driving motor 43 to move, and the position of the cutting blade 431 is changed, so that the cutting blade 431 can cut the heat dissipation film at different positions.

[0048] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto.
