[0037] Please refer to the accompanying drawings in the specification. This utility model provides a technical solution: a thermal grease coating device that automatically adjusts the flatness and thickness of the coating, comprising:

[0068] The following specific examples illustrate the working principle of the thermal grease coating equipment that automatically adjusts the coating flatness and coating thickness:

[0069] For preparation, firstly, the night before work, fill syringe 224 with thermal grease and install the syringe stopper and adapter, allowing it to settle. Failure to settle will result in air bubbles during application, affecting heat dissipation. Additionally, the application length can be adjusted according to the different sizes of the heat sink. For example, in this embodiment, the thermal grease application size for the heat sink is a rectangle of 37*47 (mm), with a thickness of 0.1-0.15 mm.

[0070] During operation, first press the reset button on the device's button panel 122 to return the entire device to zero.

The Y-axis will move the tooling mechanism 300 to its starting position, and simultaneously, the X-axis will move the head mechanism 200 to its starting position.

If, during the application process, the heat sink's surface is not perfectly flat due to manufacturing errors, the mounting plate 222 and pulley 242 can be slightly adjusted up and down to automatically adjust the scraper 230 and ensure flatness with the heat sink surface. After the thermal grease is applied, the head mechanism 200 and tooling mechanism 300 in the X, Y and Z axes all return to the zero position. At this time, the production personnel can then load and unload materials.
