In the air tightness testing of various parts of the mobile phone, the mobile phone camera is the top priority. Regarding the air tightness protection of the mobile phone camera, the back shell of the mobile phone camera is one of the key points for manufacturers to conduct air tightness testing.When leaving the factory, manufacturers often test the air tightness of the back shell of mobile phone cameras. Traditional air tightness testing has many limitations in practical operations.Hairis Technology has made many breakthroughs in the air-tightness testing of various components of mobile phones, as well as the air-tightness testing of the entire mobile phone. This is not only reflected in technology, but also in terms of solutions that are more mature.This time we will share the air tightness test of the back shell of the mobile phone camera, hoping it will be helpful to everyone.

1. Display of the appearance and detection difficulties of the mobile phone camera back shell

1. The back shell of the mobile phone camera is in the shape of a regular rectangular parallelepiped and is made of black waterproof shell material. There are three air outlets in a row in the middle and upper surface of the back shell of the mobile phone camera;

2. The shape of the back shell of the mobile phone camera is highly precise, so traditional detection methods are not suitable. How to solve the detection difficulties is also one of the important problems in its research.

2. Breakthroughs in the detection difficulties of mobile phone camera back shells and the detection process

1. There are different detection methods for different models of mobile phone camera back shells.Hairis Technology has customized a special mold based on the appearance characteristics of the mobile phone camera back shell. The mobile phone camera back shell is placed into the mold. Since there are three ventilation holes on the surface of the mobile phone camera back shell, as long as the mobile phone camera back shell is placed upward into the mold, the upper mold will block the ventilation holes. During the inspection, the instrument will inject gas into the interior of the mobile phone camera back shell through the upper mold;

2. When testing, just place the back shell of the mobile phone camera in the mold, set the program, and close the air outlet of the upper mold. When the instrument is started, it will automatically inflate the inside of the air outlet above the back shell of the mobile phone camera. At the same time, the air pressure of the instrument will slowly rise. When the air pressure reaches the set value, the inside of the high-voltage protection device will be in a constant state. At this time, the induction line will determine the flow value to detect whether the air flow inside the device meets the standard.
