Vibrating motor dispensing

Mobile phone vibration is realized by the vibration motor built in the mobile phone. At present, with the mobile phone body becoming thinner and thinner, the vibration motor is becoming smaller and smaller. In a compact and narrow space, the dispensing is inseparable from the mobile phone motor by virtue of the advantages of glue bonding and protecting various components.

Process characteristics

UV adhesive is widely used in the production of vibration motor, which requires high consistency of coating. It is necessary to overcome the influence of the liquid level difference of the rubber material in the needle cylinder. The difficulty of dispensing process is generally reflected in the filling process of small components. It is required that the magnetic and UV glue materials used for filling should be evenly coated. The use of contact needle dispensing is easy to cause fluctuations in the filling amount difference.
