[0002] As we all know, the middle frame of a mobile phone is an important component of the mobile phone body. It is the shell structure around the mobile phone for protecting the mobile phone. The safety of the middle frame of the mobile phone is related to the safety of the entire mobile phone. Therefore, in order to improve the overall safety of the mobile phone, a glue sprayer is required to spray the middle frame of the mobile phone during the production process of the mobile phone. During the spraying, a fixture is also required to clamp the two ends of the middle frame of the mobile phone so as to stably spray the middle frame of the mobile phone during the spraying.

[0003] However, the existing spraying fixture is often relatively fixed in a position when clamping the middle frame of the mobile phone, so that after the sprayer finishes spraying, the clamping position of the fixture needs to be replaced to supplement the spraying of the blank area clamped by the fixture. The process is cumbersome and it is easy to cause the coating of the middle frame of the mobile phone to be sprayed unevenly, making it difficult to ensure the spraying effect. In view of this, the present utility model is specially proposed. Utility Model Content

The two ends of the telescopic airbag 14 are respectively fixed to the connecting rod 12 and the movable contact strip 13. One side of the telescopic airbag 14 is connected to an air injection pipe 15. The upper end of the air injection pipe 15 passes through the connecting rod 12 and the set 11 and is connected to the three-way electromagnetic 16. The front end of the set 11 is threadedly connected to a positioning bolt 17;

[0033] A controller 18 is fixed to the side wall of the support 1. Considering that the existing spraying fixture is often relatively fixed in a position when clamping the mobile phone middle frame, it is necessary to replace the clamping position of the fixture after the spraying machine is finished spraying, and to supplement the spraying of the blank area clamped by the fixture. The process is cumbersome and it is easy to cause the coating of the mobile phone middle frame to be sprayed evenly, making it difficult to ensure the spraying effect. The utility model uses multiple positioning fixtures to fix the mobile phone middle frame from the inside of the mobile phone middle frame that needs to be painted, so that the spraying equipment can be not blocked by the fixture when spraying the outer part of the mobile phone middle frame, thereby ensuring the mobile phone There is no need to worry about the uneven paint spraying on the outer surface of the middle frame side caused by re-fixing the mobile phone middle frame clamp. When fixing, the mobile phone middle frame is placed on the outside of the kit 11, and then the switch of the air pump is started.
