Description

A kind of charger pneumatic coating method

technical field

The invention relates to the field of charger processing, in particular to a pneumatic coating method for chargers.

Background technique

In order to prevent scratches on the surface of the finished charger, it is necessary to cover the outer shell of the finished charger with a protective film. In the prior art, the pin surface and USB surface of most chargers do not need to be covered with a protective film. After wrapping around the main body of the charger shell, both ends of the protective film can be bonded. With the upgrading of products, some chargers need to be covered with one-piece protective film on all six sides (that is, including the pin side and the USB side). The corners do not need to be coated, which is the non-coated area. Due to the complex appearance of the protective film and the many surfaces of the product that need to be coated, the manual coating method cannot be used for accurate positioning, which is greatly affected by the operator's coating level. The phenomenon that the envelope is offset and skewed seriously does not meet the customer's requirements, and the labor is heavy and physical, which greatly troubles the charger manufacturer.
