Abstract
Description
Technical Field
[0001] The utility model is applied to the technical field of product function detection, and particularly relates to a function testing device for electronic products. Background Art
[0002] With the rapid development of electronic products, waterproof and dustproof have become basic functions of mobile phones and electronic watches. When producing such electronic products, in order to ensure that the products have the required waterproof and dustproof performance when they are produced, the produced electronic products need to be tested for waterproof and dustproof. Nowadays, most of the waterproof tests of some electronic products use liquid water to simulate the actual environment. Therefore, when testing the products, it is impossible to determine whether the tested products have the required waterproof performance. When some products do not have a certain waterproof performance, liquid water will enter the inside of the product, thereby damaging the electronic products, increasing the maintenance cost, or even directly scrapping the electronic products.
[0003] The existing technology requires the use of two devices for testing, first the waterproof and dustproof test equipment, and then the product function test equipment. Each test device can only test a single item, which not only increases the test cost, but also is not conducive to process control. Electronic products are easily damaged, and maintenance costs and maintenance time are increased. Therefore, it is necessary to provide a functional test device for electronic products that has a compact structure, can reduce maintenance costs, simplify processes, and can perform both waterproof and dustproof tests and product function tests.

The host is connected to the analog input and output module via the controller, and the analog input and output module controls the flow of the air supply and exhaust valve.

[0006] It can be seen from the above scheme that the present application can perform waterproof and dustproof testing and product function testing, can control the testing process, reduce the risk of damage to electronic products, reduce maintenance time, reduce maintenance costs, simplify the process, and improve efficiency.
[0007] A preferred solution is that the functional testing device for the electronic product further comprises a second leakage pressure measuring device, and the product is connected to the pressure sensor via the second leakage pressure measuring device.
