After completion, the first electric push rod 18 and the second electric push rod 24 reset and take out the electrode after the glue is completed. The motor 13 drives the feeding roller 4 to continue to pull the tape 1 for feeding. After the feeding is completed, a new electrode is inserted and the above operation is repeated for glue sticking.
