Device for printing laser crystal cooling heat sinks and method thereof

[0035] Such as figure 1 As shown, a device for printing a laser crystal cooling heat sink includes a workbench 8, a laser crystal 1, a first clamp 21, a second clamp 22, a second support block 4, a first motor 3, a second motor 9, a laser 5. Powder feeder 6 and control module 7. The second support block 4, the first motor 3, the second motor 9 and the laser 5 are all fixedly connected to the surface of the workbench 8, the laser crystal 1 is cylindrical, and the first clamp 21 and the second clamp 22 are cylindrical, respectively against On both ends of the laser crystal 1, the area of ​​the abutting surface of the first fixture 21 is larger than the area of ​​the end surface of the laser crystal 1 abutting against it, and the area of ​​the abutting surface of the second fixture 22 is larger than the area of ​​the end surface of the laser crystal 1 abutting against it. The two faces of the fixture that are against the laser crystal completely cover the two end faces of the laser

[0044]When printing the cooling heat sink on the surface of the sheet-shaped laser crystal 1, the same part as the embodiment (1) will not be repeated, the difference is: the first motor 3 is not needed, and the third motor is fixedly connected to the laser 5 side. The three motors are connected to the control module 7, and the third motor drives the laser 5 to move in a plane perpendicular to the workbench 8. The sheet-shaped laser crystal 1 is placed perpendicular to the workbench 8, and the surface of the cooling heat sink 11 that needs to be printed faces the laser 5 . The laser beam 51 forms a "back" path on the surface of the laser crystal 1 .
