Assembly jig and assembly leak-detection system

Abstract

The invention discloses an assembly jig and an assembly leak-detection system. The assembly leak-detection system comprises a waterproof leak-detection device and the assembly jig. A test air circuitis formed by the waterproof leak-detection device and an air passage through an air pipe, and test results are outputted through detection and comparison between the pressure of the test air circuit and standard pressure. A connector of a control valve group is connected with an air pump, a standard cavity connector and a test cavity connector through air pipes to at least form a positive-pressuretest air circuit and a negative-pressure test air circuit. A positive-pressure throttle valve is connected into the positive-pressure test air circuit, and a negative-pressure throttle valve is connected into the negative-pressure test air circuit. A detection terminal of a pressure difference transmitter is connected into air circuits of the standard cavity connector and the test cavity connector. A detection terminal of a pressure transmitter is connected into the positive-pressure test air circuit and the negative-pressure test air circuit. The assembly jig and the assembly leak-detectionsystem have the advantages that assembly and test processes can be completed on the same jig, so that transfer process is omitted, and working efficiency is improved effectively.

Description

technical field [0001] The invention belongs to the technical field of assembly and testing of electronic products, and in particular relates to an assembly jig and an assembly leak detection system. Background technique [0002] With the development of technology and the improvement of people's living standards, electronic products have been greatly developed, and their functions are not only more and more rich and powerful, but also more and more beautiful and small in size. General electronic products include many electronic components and various cables, which realize corresponding functions through organic combination. In order to improve safety during use, almost all electronic products are required to meet a certain level of waterproof requirements. In order to meet the waterproof requirements of electronic products, it is required to be easy to use on the production line during and after the assembly process of the production line. However, in the prior art, after t...

Problems solved by technology

However, in the prior art, the parts of electronic products are assembled and then tested for waterproofing through testing equipment. This method separates the two links of assembly and leak testing, resulting in a long working cycle, which is not conducive to the improvement of efficiency.

At the same time, the test method is cumbersome and the structure of the test equipment is complicated.

Therefore, it is impossible for every product to be tested in real water. The alternative test method is to use air pressure to simulate water pressure to test the product while ensuring its accuracy and readability. However, there is currently no such application. Test Equipment for Test Methods
