AI Technical Summary

Technical Problem

The paper roll mechanism of existing silicon wafer printing machines, driven on the same side, is prone to causing the paper roll to deviate from the center, making it impossible to maintain a straight direction for silicon wafer transport.

Method used

By installing unwinding and rewinding motors on both sides of the printing platform, the unwinding and rewinding of the paper roll are controlled separately, ensuring that the paper roll is transported to the silicon wafer in a straight line.

Benefits of technology

It effectively prevents the paper roll from becoming eccentric, ensuring that the silicon wafers are transported smoothly in a straight direction, especially maintaining stability during the transport of large-size silicon wafers.
