And putting down the barrier strips 6, respectively bonding the second protective cover films of the two sections of nanocrystalline strips at the new end by using two 4cm by 5cm third adhesive tapes, lifting the second protective cover films by using the third adhesive tapes, so as to lift the second protective cover films of the two sections of nanocrystalline strips, respectively and temporarily bonding the two third adhesive tapes on the two barrier strips 6 after lifting the second protective cover films of the two sections of nanocrystalline strips, so that the second protective cover films of the two sections of nanocrystalline strips are kept in a lifted state at the new end, which is easy to understand, and after the second protective cover films are lifted, the material layers of the nanocrystalline strips are exposed at the new end.
And adhering the material layers of the two sections of the nanocrystalline strips by using a second adhesive tape with the width of 5 cm.
And then tearing off the third adhesive tape from the two barrier strips 6, disconnecting the third adhesive tape from the barrier strips 6, resetting the second protective covering film of the nanocrystalline strip, tearing off the third adhesive tape on the second protective covering film of one section of nanocrystalline strip, and connecting and fixing the second protective covering films of the two sections of nanocrystalline strips by using the other third adhesive tape.
And finally, closing the magnetic table 1 by using the control switch 12 to complete the joint of the two sections of nanocrystalline strips.
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.
