What are the requirements for air tightness test of pet tracker and positioner?

Pet tracker and GPS locator belong to electronic communication equipment. Due to the particularity of equipment application scenarios, they are often used outdoors, often exposed to the impact of special weather conditions, rain and air will bring certain corrosiveness to the equipment. If the sealing condition of the equipment is poor, the external environment will bring irreversible damage to the internal components of the equipment, so the sealing detection of pet tracker and locator is very important.

Hermes technology has made great achievements in the field of seal detection. Seal detection of pet tracker and locator is also one of the research focuses of Hermes technology. Today, we will share a case about the seal detection of pet tracker. I hope you can take it as a reference.

1、 Sealing test requirements of pet tracker and positioner

1. As a wearable device, its volume is small. As an intelligent device, its precision is very important. The accuracy of the display is the focus of people's attention. Therefore, we should pay more attention to the nondestructive, accuracy and operability of the sealing test when testing;


2. Due to the high precision of the equipment, it is not easy to carry out direct detection, so the indirect detection method will be used to ensure that the equipment is more convenient and the results are more accurate.

2、 Pet tracker, locator sealing test process display

1. Because there is a connecting wire behind the pet tracker, its sealing degree should be considered when testing, so Harris technology has customized a special testing mold for it to fix. The products to be tested are placed in the mold, and the whole shape and mold fit each other, so it is more convenient for the upper and lower mold to close tightly when testing;

3. Before testing, it is necessary to set the value on the sealing testing equipment. Then, put the testing product into the mold, press the start button, and the upper and lower molds are closed to form a closed space for the pet tracker. The tube connecting the detector will fill the mold with dry and impurity free gas, The instrument will judge whether the sealing of the product meets the standard through the air pressure inside the mold;

3. The airtightness tester has high automation, short detection time and simple operation interface. 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.
