Description

Technical Field

[0001] This utility model relates to the field of nut implantation technology, and in particular to a nut hot-melt implantation machine. Background Technology

[0002] Currently, plastic parts are widely used in equipment housings in the electronics, communications, and electrical appliance industries. During the same production process, different housings often need to be connected together using nuts and screws. This requires heat-melting and embedding the nuts into the plastic housing parts.

[0003] To quickly heat-melt nuts into corresponding positions on plastic parts, existing technology typically uses a nut heat-melt insertion machine. This machine usually includes a frame, an insertion device mounted on the frame for preheating the nuts and pressing them into the plastic part, a feeding device for conveying the nuts to the insertion device, and a CNC device for controlling the insertion device and automating its operation. This allows for efficient and automated nut insertion. However, this technology also has some limitations. For example, it can only insert nuts vertically into the flat surface of the plastic part, but some customers require nuts with beveled edges (0-45°) around the edges to connect upper and lower caps. Therefore, during production, it is often necessary to create a carrier with the appropriate angle based on the product's bevel before using existing automated nut insertion equipment. Furthermore, a single plastic part often has multiple bevels with different angles, or requires simultaneous nut insertion at multiple locations. This results in cumbersome operations and low efficiency in mass production.

[0004] Therefore, a high-efficiency nut hot-melt implantation machine capable of implanting nuts into inclined surfaces needs to be designed. Utility Model Content
