Description

Technical Field

[0001] The present invention relates to a device for applying a colloid to a fastener. Background Art

[0002] When a rivet nut fixes an object, a gap will be generated between the seat surface of the rivet nut and the material to be riveted, which will affect the riveting sealing state and even its stability. Therefore, before leaving the factory, a colloid is applied to the seat surface of the rivet nut to increase the friction and tightness between the seat surface of the rivet nut and the material to be riveted and fill the gap.

[0003] However, currently in the rivet nut production line, the rivet nuts are coated with glue one by one. In addition, for some specifications of rivet nuts, the seat surface area is small, and it is difficult for the colloid to completely adhere to the seat surface. It is necessary to apply the colloid to the seat surface little by little in a manual multi-point glue application method, which leads to a reduction in production capacity and cannot meet customer requirements. Summary of the Invention

[0004] The present invention provides a fastener glue application device for simultaneously attaching a colloid to the seat surfaces of a plurality of fasteners.

[0005] The fastener glue application device provided by the present invention has:

[0006] An adjustment mechanism having:

[0007] A first rotating shaft;

[0008] A carrier seat capable of rotating around the first rotating shaft;

[0009] A first rotating cylinder connected to the first rotating shaft and capable of driving the first rotating shaft to rotate, thereby driving the carrier seat to rotate around the first rotating shaft;

[0010] A second rotating cylinder disposed on the carrier seat;

[0015] A plurality of auxiliary glue guns are pivotally mounted on the carrier seat and are spaced apart and parallel to the main glue gun assembly;

[0016] A connecting rod assembly connects the glue gun assemblies; when the second rotating shaft drives the main glue gun assembly to rotate, the connecting rod assembly drives the auxiliary glue gun assemblies to rotate.

[0017] The advantages of the present invention are that the colloid can be simultaneously attached to the seat surfaces of a plurality of fasteners through multiple glue gun assemblies of the dispensing mechanism. In addition, the angle of the glue gun assemblies can be adjusted through the adjustment mechanism. Thus, when the seat surface is small or non-planar, the fastener gluing device can adjust the angle of the glue gun assemblies according to the seat surface, thereby improving production efficiency.

[0045] Please refer to Figures 2 to 5 。The adjusting mechanism 10 has a first rotating cylinder 11, a first rotating shaft 111, a bearing seat 12, a second rotating cylinder 13 and a second rotating shaft 131. The first rotating cylinder 11 is connected to the first rotating shaft 111 and can drive the first rotating shaft 111 to rotate, thereby driving the bearing seat 12 to rotate back and forth with the first rotating shaft 111 as the axis. The second rotating shaft 131 is disposed on the bearing seat 12. The second rotating cylinder 13 is connected to the second rotating shaft 131 and can drive the second rotating shaft 131 to rotate.

[0046] The dispensing mechanism 20 is disposed on the adjusting mechanism 10 and has a plurality of glue gun assemblies and a link assembly 23. The glue gun assemblies are disposed on the adjusting mechanism 10 and can attach the colloid to the seat surface of the fastener A. The extending directions of the glue gun assemblies are parallel to each other. The glue gun assemblies include a main glue gun assembly 21 and a plurality of sub-glue gun assemblies 22.

[0047] The main glue gun assembly 21 is fixed on the second rotating shaft 131, and when the second rotating shaft 131 rotates, the main glue gun assembly 21 rotates with the second rotating shaft 131 as the axis. 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. The main fixing seat 211 is connected and fixed to the second rotating shaft 131 through the fixing holes 213, and the main fixing seat 211 can swing left and right as the second rotating shaft 131 rotates. The main glue gun 212 is disposed on the main fixing seat 211 and can attach the colloid to the seat surface of the fastener A.

[0048] The sub-glue gun assemblies 22 are pivotally mounted on the bearing seat 12, and the sub-glue gun assemblies 22 are spaced apart and parallel to each other and are spaced apart and parallel to the main glue gun assembly 21. Each sub-glue gun assembly 22 has a sub-fixing seat 221 and a sub-glue gun 222. The sub-fixing seat 221 is pivotally mounted on the bearing seat 12 and has a pivot hole 223. The sub-fixing seat 221 is pivotally mounted on the bearing seat 12 through the pivot hole 223 and can rotate with the pivot hole 223 as the axis.
