Description

Technical Field

[0001] The present invention relates to the technical field of digital tube production detection, and more particularly to an LED digital tube detection device and detection method. Background Art

[0002] LED digital tubes are used to display numbers and other information and are widely used. During the production process, the power supply status of the digital tubes needs to be tested to ensure that qualified digital tubes enter the market. The digital tubes are arranged with multiple pins, each of which corresponds to a different segment on the digital tube. People usually use the positive and negative probes of a multimeter to touch the pins one by one. If the pin being tested is not damaged, the segment of the digital tube will light up. If the pin being tested is damaged, the segment of the digital tube corresponding to the tested pin will not light up, thus testing the digital tube.

[0003] Existing detection machines need to connect multiple digital tubes in series into strips for collective detection. In order to improve the detection accuracy of the strip digital tubes, it is necessary to manually lift and lower the strip digital tubes multiple times for multiple detections, and then manually discharge the strip digital tubes that have completed the detection. The number of manual lifting and lowering times is small, which may easily lead to insufficient detection accuracy. Conversely, it may easily cause a single strip digital tube to take a long time. Long-term manual work may also easily lead to fatigue and detection errors. Summary of the Invention
