Description

Technical Field

[0001] The utility model relates to the technical field of earphone charging box processing, in particular to a quantitative feeding mechanism for magnet assembly. Background Art

[0002] Headphone charging boxes are usually used to store and charge headphones or wireless headphones. Such devices usually have a built-in battery and charging port to charge the headphones and facilitate carrying.

[0003] During the production process of the earphone box, magnets need to be installed on the box cover. The function of the earphone box magnet is to absorb the earphones, so that the earphones are fixed in the box and not easy to fall out. At the same time, the magnet also helps the earphones to connect and charge automatically. When the box cover is closed, the magnet will attract the metal contact of the earphones, so that the earphones and the box are connected, and charging will begin.

[0004] At present, during the process of installing and feeding the magnets in the earphone box, they are only transported and installed through a single material channel and the cooperation of a robot. However, since the magnets have a certain magnetic property, the magnets are easily adsorbed together when transported in this way, resulting in inconvenience in feeding. Therefore, we propose a quantitative feeding mechanism for magnet assembly to solve the above problem. Utility Model Content

[0012] In a preferred embodiment of the utility model, mutually compatible laser detectors are installed on both sides of the feeding base plate, and the feeding trough is located on the detection path of the laser detector. The residual material is detected by the laser detector. When there is no residual material, the rotating barrel rotates to rotate the next feeding mold to the bottom of the blowing nozzle.
