Parameter analysis of sealing tester for shared bicycle lock

Bike sharing, as a new form of transportation to solve people's travel problem in the last mile, can be seen in every corner of the city. When we use it, we usually "scan" the bicycle's QR code. After a series of short operations, the car lock will open in response to the sound, and you can ride after unlocking. For bike sharing, the existence of car lock is very important. Bike sharing lock is different from ordinary car lock. It is intelligent and easy to use. Therefore, the seal of car lock is very important. Hiris technology has made a lot of research in the field of sealing detection, and has made great achievements in the application of shared bicycle lock.

1、 Requirements of shared bicycle lock for sealing test

1. The volume of shared bicycle lock is small. As an intelligent device, its precision and display accuracy are the focus of people's attention, so we should pay more attention to the non-destructive, accuracy and operability of 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 in this test to ensure that the equipment is more convenient and the results are more accurate.

2、 Demonstration of sealing test process of shared bicycle lock

1. For the products tested this time, Harris technology has customized a special mold. The mold is cast according to the shape of vehicle speed. In order to better fix the car lock in the mold, there is a special groove on the mold for placing the car lock connecting wire. In this way, when testing, the upper and lower molds are closed to form a completely closed space, which is more conducive to testing;

2. Before testing, set the program on the tester and press the start key. With the instruction of the instrument, the tooling is closed up and down to form a closed space for the test product. Then, the pipe connecting the instrument injects impurity free gas into the mold, and the instrument will judge whether the seal of the pet tracker 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.
