Breakthrough in water proof test of multi channel electric toothbrush
Electric toothbrush is a kind of tool which can make the brush head vibrate with high frequency through the rapid rotation or vibration of the motor core to promote tooth cleaning. It can be divided into two types: plug-in power supply and battery drive. But no matter which type of electric toothbrush, its waterproof is very important, whether it is in the production of special waterproof treatment, or in the later period for the product waterproof test, is a safety protection for consumers using electric toothbrush.
For the waterproof test of electric toothbrush, different testing businesses have different methods, but in the face of a variety of types of electric toothbrush, there is little breakthrough in the waterproof test. And Harris technology for different types of electric toothbrush waterproof test always has its own set of solutions. This time we will share a case of multi-channel electric toothbrush waterproof test at the same time for your reference.
1Appearance display and testing difficulties of electric toothbrush
1. There are three electric toothbrushes to be tested for water resistance this time. They are all made of cylindrical handlebars wrapped with waterproof materials and irregular brush heads, with obvious interface;
2. There are three circular electric quantity display areas on the handle of electric toothbrush. Up there are switch buttons, totally closed waterproof structure and special shape. It can't be fixed when testing, so it can be tested directly.
2、 Breakthrough of testing difficulties and testing process of electric toothbrush
1. Harris technology will customize the mold according to the overall condition of the electric toothbrush, so that the electric toothbrush can be stuck in the mold. This time, it is aimed at the simultaneous detection of three electric toothbrushes. In order to save time, Harris has a special three position detection tooling. As long as the three electric toothbrushes are put into the mold respectively, the upper and lower parts of the mold will close the electric toothbrush, Form a sealed environment around.
instrumentIt is integrated with the tooling of three working positions. As long as the program is set before the test, the instrument will be stable during the testTo dieininflation. If电动牙刷Is not sealed, the phenomenon of air leakage, when the instrument leakage value display data is also increasing, at the same time, the pressure value decreases. At this time, it can determine whether the wire connector leaks, and the instrument test results will also show ng, which means that the air tightness test does not pass. If the tested wire connector 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 "OK", indicating that the air tightness test has passed.
