Demonstration of air tightness testing process of electric toothbrush back shell

As the charging part of the electric toothbrush, the back shell of the electric toothbrush is internally connected with charging parts. People have higher requirements for its safety. If its safety is not high, the external water mist will enter the shell through the gap, damage the internal charging system, and cause the shell can not be used normally. Therefore, it is very important to detect the air tightness of the electric toothbrush back shell.

Hiris technology has also done a lot of research on the air tightness detection of the electric toothbrush back shell. While solving many detection problems, hiris's air tightness detector has also been used in the production line. This time, we will share a case of air tightness test of electric toothbrush back shell for your reference.

1、 Air tightness test requirements of electric toothbrush back shell

1. The overall precision of the back shell of the electric toothbrush which needs to be tested this time is high. The pink waterproof shell material is used for casting. There are two connecting holes at the top and front of the back shell of the electric toothbrush;

2. For the air tightness test of the electric toothbrush back shell, we need to overcome two points: the nondestructive test of the product and the accuracy of the results. Because the overall shape of the electric toothbrush back shell is special, it is difficult to fix it when testing, so it needs to use a special mold to fix it, and adopt indirect testing method.

1. This time, we need to carry out multi-channel simultaneous detection, so we need to use multi-channel air tightness detector to carry out air tightness detection. The instrument has the advantages of realizing three channel simultaneous detection, and the detection equipment is designed with slide plate, which is less noise, safer and more efficient;

2. Due to the special structure of the back shell of the electric brush, Harris technology has developed a mold for it to place the back shell of the electric toothbrush. Only before the detection starts, put the back shell into the mold, set the mode, and the upper mold will be closed with the lower mold to form a closed space; The instrument will directly inflate into the mold. When the internal gas reaches the saturation state, it can judge whether the air tightness of the electric toothbrush back shell is qualified through the air pressure condition inside the mold.

3. In the detection, the inflation port at the back of the mold is connected with the tube to inflate the mold. If the back shell of the electric toothbrush is not sealed, there will be air leakage. At this time, the leakage value in the instrument will be larger and larger, and the pressure value will drop. At this time, it can determine whether the vehicle controller is leaking, and the instrument test results will also show ng, which means that the air tightness test does not pass. If the back shell of the tested electric toothbrush does not leak, the gas in the tooling die will be in a constant state after inflation, the pressure value and leakage value displayed on the instrument are also stable, and the test result of the instrument will display the word OK, indicating that the air tightness test has passed.

3、 Advantages of using multi-channel air tightness detector

(1) Save time and cost; The detector can provide three detection channels, and can detect three camera lenses at the same time. The test speed is three times faster than usual, which is more conducive to saving time and cost.

(2) Lower equipment cost; The three channel tightness tester is controlled by three testing equipment and three working positions. It only needs one person to operate. It simplifies the manpower for the enterprise and optimizes the capital chain of the manufacturer.

(3) It has strong operability and high efficiency; The tester is also equipped with "positive and negative" pressure forms and 8 Basic test modes, which can be selected or combined. Using 24 bit a / D conversion, 32-bit CPU operation, and fully independent development of industrial control operating system, with full touch human-computer interface. Built in RS232 serial port, RJ45 network port, USB communication interface, LTP external I / O control port, support a variety of communication protocols, diversified self-service operation, artificial and intelligent combination, enhance the operability of the device.
