Description

Technical Field

[0001] This utility model relates to a device for applying colloid to fasteners. Background Technology

[0002] When rivets and nuts fasten objects, gaps can form between the rivet / nut seat and the materials being riveted, affecting the sealing and even the stability of the connection. Therefore, before leaving the factory, rivets and nuts are coated with an adhesive to increase friction and tightness between the seat and the materials being riveted, and to fill any gaps.

[0003] However, currently in rivet and nut production lines, rivets and nuts are coated with adhesive one by one. Furthermore, some sizes of rivets and nuts have small seat surfaces, making it difficult for the adhesive to adhere completely to the seat surface. This necessitates manual application of adhesive in multiple dots, resulting in reduced production capacity and an inability to meet customer demands. Utility Model Content

[0010] A second rotating cylinder is disposed on the support base;

[0011] A second rotating shaft is connected to the second rotating cylinder; the second rotating cylinder can drive the second rotating shaft to rotate.

[0016] A linkage assembly is provided, which connects to the glue gun assembly; when the second rotating shaft drives the main glue gun assembly to rotate, the linkage assembly drives the auxiliary glue gun assembly to rotate.

The extension directions of the glue gun assemblies are parallel to each other. Each glue gun assembly includes a main glue gun assembly 21 and a plurality of auxiliary glue gun assemblies 22.

[0047] The main glue gun assembly 21 is fixed on the second rotating shaft 131, and rotates about the second rotating shaft 131 as its axis when the second rotating shaft 131 rotates. The main glue gun assembly 21 has a main fixing seat 211 and a main glue gun 212. The main fixing seat 211 is fixed on the second rotating shaft 131 and has a plurality of fixing holes 213.
