Description

Technical Field

[0002] The traditional packaging process of bolts and nuts is to spread plastic film on the ground, put the bolts and nuts on it, and the operator squats or sits to assemble and package. The assembly is done manually, with one hand holding the bolt and the other holding the nut, screwing the screw into the bolt. After assembling one set, pick up another set from the ground and assemble it again. The assembly of bolts and nuts with shorter bolts is relatively simple, but the assembly of nuts with longer bolts takes a long time and requires multiple turns to assemble the nuts to the appropriate position. The relevant staff consumes a lot of physical strength and has low work efficiency. Summary of the invention
