Circuit board test system having magnetic adsorption function and test method thereof

Abstract

The present invention relates to a circuit board test system having the magnetic adsorption function. The system comprises a magnetic adsorption device A, a magnetic adsorption device B, a signal transfer terminal board and a test device. The magnetic adsorption device A comprises a clamping seat A fixed on a test circuit board, a magnetic core A and a metal probe A both arranged in the clamping seat A. The magnetic adsorption device B comprises a clamping seat B, a magnetic core B and a metal probe B both fixedly arranged on the clamping seat B. According to the technical scheme of the invention, the magnetic adsorption device A is arranged on the circuit board with the signal input. The magnetic adsorption device A, matched with the circuit board, is in connection and conduction with the circuit board. The magnetic adsorption device A and the corresponding magnetic adsorption device B are naturally adsorbed and communicated with each other under the action of the magnetic force. On a production station, the magnetic adsorption device B is fixedly connected with all signal input lines. In this way, the process of connecting / disconnecting each machine with a signal line is avoided. Not only the abrasion of each main board caused by the connection / disconnection of each machine is reduced, but also the signal matching accuracy is greatly improved. The production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of circuit boards, and more specifically relates to a device and a testing method for installing a magnetic adsorption device on a factory assembly line to improve production and test circuit boards. Background technique [0002] At present, factories that produce circuit boards or produce electronic products, without exception, must perform signal detection of each channel at the production station. Taking the production of TV sets as an example, when producing and assembling TV sets, the circuit board must be checked at the production station. Or confirm the signal channel of the circuit board installed on the whole machine. Simply speaking, it is necessary to plug in the HDMI terminal, VGA terminal, AV terminal, YPbPr terminal, network port terminal, Tuner terminal and USB terminal on the TV. Signal line for signal confirmation. During the production process, for each motherboard or machine that comes on...

AI Technical Summary

Problems solved by technology

In the production process, for each motherboard or machine that comes over the assembly line, these input signal lines must be plugged in and out again, which is time-consuming and labor-intensive, which not only greatly increases the labor intensity of workers, but also seriously affects production efficiency.
