Adhesive applicator for threaded devices and process for applying adhesive to threaded devices
View Patent ↗An adhesive applicator includes a base portion and an adhesive distributing portion. The base portion includes a first passageway extending from the exterior of the base portion to and through an integral cylindrical portion of the base portion. The adhesive distributing portion includes a plurality of passageways therethrough in communication with the first passageway of the base portion. The plurality of passageways of the adhesive distributing portion extend to the exterior of the adhesive distributing portion. An adhesive pump forces adhesive to and through the first passageway of the base portion and into and through the plurality of passageways of the adhesive distributing portion to the exterior of the adhesive distributing portion. Adhesive emanates from the exterior of the adhesive distributing portion under the force of the adhesive pump and coats the threads of an internally threaded device. Another example coats the threads of an externally threaded device. Processes for coating internal and external threads are disclosed.
1. A process of applying adhesive to a threaded device, comprising the steps of:
placing said threaded device upon a base portion of an adhesive applicator, said base portion supporting said threaded device;
pumping anaerobic adhesive, utilizing a peristaltic pump, from an adhesive reservoir to said adhesive applicator for coating threads of said threaded device;
routing said adhesive through a first passageway in said base portion of said adhesive applicator;
routing said adhesive through a plurality of passageways in an adhesive distributing portion of said adhesive applicator;
discharging adhesive from said plurality of passageways to an exterior of said adhesive distributing portion of said adhesive applicator, said threaded device surrounding said exterior of said adhesive distributing portion proximate said threaded device;
forcing adhesive into a gap between said adhesive distributing portion and said threaded device; and,
coating said threads of said threaded device with said adhesive.
2. The process of applying adhesive to a threaded device as claimed in claim 1 wherein said step of discharging adhesive from said plurality of passageways to said exterior of said adhesive distributing portion proximate said threaded device is followed by the step of spreading said adhesive in a circumferential groove in said exterior of said adhesive distributing portion of said adhesive applicator proximate said threaded device.
3. The process of applying adhesive to a threaded device as claimed in claim 2 wherein said plurality of passageways in said adhesive distributing portion of said adhesive applicator are radial passageways.
4. The process of applying adhesive to a threaded device as claimed in claim 1 , further comprising the step of:
draining excess adhesive from said gap between said adhesive distributing portion and said threaded device.
5. The process of applying adhesive to a threaded device as claimed in claim 4 wherein said plurality of passageways in said adhesive distributing portion of said adhesive applicator are radial passageways.
