Description

Technical Field

[0001] This utility model relates to the field of fastener production equipment technology, specifically to an automatic fastener feeding, dispensing, and gluing device. Background Technology

[0002] The chemical adhesives used on fasteners and screws are usually called fastening adhesives or anaerobic sealants. These adhesives are primarily used to ensure that screws do not come loose during operation.

[0003] During the gluing process, the fasteners are conveyed to the transmission track by feeding devices such as vibratory feeders, and then transported in a single row to the glue spraying device to spray chemical glue, which covers the threaded part of the fasteners.

[0004] The problem with the existing technology is that fasteners are small parts produced in large quantities. During the conveying and gluing process, the dense fasteners need to be separated one by one in order to fully apply the glue to the separated fasteners and avoid interference between the fasteners, which would hinder the gluing of each other.

[0005] At the same time, in order to standardize the glue application process, it is necessary to ensure that the positional relationship between each fastener and the glue spraying mechanism is fixed during glue application, so as to ensure a uniform glue application effect.

[0006] Therefore, it is necessary to design a device that automatically delivers and separates fasteners, so that fasteners are coated with glue one by one and uniformly to achieve a standardized effect. Utility Model Content

[0015] Then the two sets of separation mechanisms operate according to the above-mentioned cycle, cooperate with the stepping operation of the rotating table, and discharge the adjacent fasteners from the vibration disc one by one, and then separate and discharge the fasteners to each magnetic base, and then the rotating table conveys the fasteners to the glue spraying mechanism for gluing.
