Description

technical field [0001] The invention relates to a voltage supply system, in particular to a voltage supply system used for continuously power-checking the performance of electronic products on a production line. Background technique [0002] At present, the mains voltage across the country is not very stable. Some rural and remote areas have low voltage, and some places have high voltage due to transformer problems. In order to adapt to the national conditions, electronic products can work more normally under abnormally low voltage or abnormally high voltage, and have stronger adaptability, so that electronic products have better performance. During the production of electronic products, it is necessary to It performs low voltage / high voltage detection to determine whether the electronic product can work under abnormal voltage. [0003] Such as figure 1 As shown, the production of electronic products is mostly operated on the production line 4 at present. The production l...

Problems solved by technology

[0007] The disadvantage of this system for online detection of abnormal voltage performance of electronic products is that: in order to prevent the tooling board 1 from simultaneously contacting the detection voltage connected to the conductive devices 5a and 5b of the detection station and the conductive devices on both sides of the other stations. For some normal working voltages, it is necessary to set the gap between the conductive devices 5a, 5b of the detection station and the conductive devices on both sides of the adjacent station to be greater than the length of the conductive strip 12 on the back of the tooling board 1

In this way, when the electronic product arrives at the detection station and a station after the detection station needs to be restarted, this will waste time and reduce production efficiency for electronic products that start slowly, especially computers or televisions.

And the distance between the detection station on the production line and its adjacent stations is greater than the length of the conductive strip 12 on the tooling plate 1 back side, so that the space on the production line is wasted, and the length of the production line increases
