In conclusion, the nanocrystalline strip joint process provided by the invention can enable two sections of nanocrystalline strips to form new matched ends, enable the new ends of the two sections of nanocrystalline strips to be in tight and smooth transition, greatly reduce the probability of bubbles and wrinkles, and effectively improve the quality and consistency of the joint of the nanocrystalline strips, thereby reducing the defects of subsequent testing stations, reducing the waste of materials and improving the production yield. And when the first protective cover films of the two sections of nanocrystalline strips are bonded, the positions of the nanocrystalline strips can be finely adjusted, so that new ends of the two sections of nanocrystalline strips are bonded, and the quality of the joint is further improved.

The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all equivalent changes made by using the contents of the present specification and the drawings, or applied directly or indirectly to the related technical fields, are included in the scope of the present invention.
