Mobile phone rear cover spraying device

The invention discloses a mobile phone rear cover spraying device, and relates to the technical field of mobile phone rear cover spraying, the mobile phone rear cover spraying device comprises a machine table, and the front surface of the machine table is fixedly connected with a fixing frame. According to the mobile phone rear cover body spraying device, when a mobile phone rear cover body is sprayed, a third motor is started to drive a driving synchronous belt to rotate along with the mobile phone rear cover body, and a belt can be driven to operate in a rectangle formed by the driving synchronous belt and a driven synchronous belt through cooperative use of rotating rods at the other three corner positions and the driven synchronous belt; when the belt runs to drive the first spray head to move along with the belt, the moving track of the first spray head is equal to the section proportion of the mobile phone rear cover body, so that when the first spray head moves to any position, the distance between the
