Description

Technical Field

[0001] This utility model relates to the technical field of solder bar winding devices, and in particular to a solder bar winding device. Background Technology

[0002] Solder bars are strip-shaped metal materials made of pure tin or tin alloys. The reasons for coiling solder bars are as follows: First, they facilitate storage and transportation. After coiling, the solder bars are neat, take up little space, and are easy to stack and secure, reducing damage during transportation and storage. Second, they prevent deformation and damage. Their soft texture allows coiling to maintain their shape. Third, they facilitate use and processing. Coiled solder bars are easier to feed into soldering equipment and allow for better control of feed speed and quantity, ensuring processing quality.

[0003] Solder bars have high hardness and poor plasticity at room temperature or in cold conditions, making it difficult to tightly bond them together during winding. This results in large gaps in the wound solder bar roll, which not only increases the volume of the solder bar roll and occupies more storage space, but also easily causes the solder bar to loosen and deform during subsequent handling and use, affecting its performance and quality stability.
