Sealing test details sharing of 3atm, 5atm and 8atm smart watches

Smart watch is a kind of watch which has information processing ability and meets the basic technical requirements of watch. As for the tightness test of smart watch, we mentioned in the previous case sharing, because the smart watch is small and delicate, for manufacturers, its high tightness is conducive to production safety, for consumers, its good tightness is conducive to ensuring its accuracy in use. Hermes has been doing a lot of research on the tightness test of smart watches, and the test quality has won the trust of customers.

1、 Difficulties in sealing test of 3atn, 5atn and 8atn smart watches

1. The only thing we need to test this time is the watch shell. The overall workmanship of the shell is relatively fine. The round metal shell material plus the glass surface covered above is used to fix the watch strap. There are two rings on the top and bottom of the shell. The right side is used to adjust the time. The overall precision is high;

2. Due to the high precision of the whole shell, it is impossible to use the method of directly inputting gas into the shell, so it is necessary to use the mold as an auxiliary test;

1. According to the special shape of smart watch, Harris technology has a customized tooling mold. Because this smart watch has a strong sealing property, when testing, just put it into the mold. The groove inside the mold is customized according to the volume of the smart watch, and it is just right when it is put in and out. In this way, the mold will be closed up and down during testing, Form a closed space;

2. When the instrument is started, the instrument will inflate into the closed mold through the upper appliance, and the air pressure of the instrument will rise slowly. When the air pressure is charged to the set value, the inside of the mold will be in a constant state. At this time, the induction tube will determine the flow value to detect whether the flow of the exhaust pipe meets the standard.

3. If the airtightness of the smart watch is not good and air leakage occurs, 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 smart watch has air leakage, and the test result of the instrument will also show ng, which means that the air tightness test fails. If the test smart watch 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 tightness test has passed.
