Embodiment Construction
[0028] see Figure 1~3 , the present invention relates to a device and method for making a silicon solar cell electrode printing screen by laser, the device includes a laser 1 (specifically, the laser 1 is a pulse laser with a repetition frequency of 10KHz and above, and the emitted The wavelength of the laser is 196nm~1064nm, and the pulse width action time is 1fs~1ms), the high-frequency pulsed laser emitted by the laser 1 passes through the shutter 2 and the beam expander 3, and then enters the surface of the laser reflector 4. After the reflection of the mirror 4, it is incident on the surface of another laser mirror 4 through the half-wave plate 5, the Glan prism 6 and the rotating module 7 (TREPANNING HEAD), and enters the vibrating mirror after being reflected by the laser mirror 4 System 8, the laser beam emitted from the galvanometer system 8 is focused by the focusing mirror 9 and is facing the workpiece 16 to be processed on the platform 13. A CCD alignment observat...
