Description

Technical Field

[0001] The utility model relates to the technical field of appearance inspection equipment, in particular to a digital tube appearance full-automatic inspection equipment. Background Art

[0002] At present, after the digital tube is produced and enters the packaging process, it is necessary to conduct appearance inspection or testing on the digital tube to ensure that the appearance of the digital tube has no defects and deformation. There are basically two methods for the appearance inspection of digital tube products. One is a semi-automatic inspection method using equipment for automatic inspection, and the other is a manual inspection method using manual visual inspection. However, the above two traditional inspection methods have some problems and shortcomings, as follows: (1) The digital tube is composed of a square digital tube shell and protruding pins at the bottom of the digital tube shell that are similar to needles; because the pins are arranged in multiple rows, and the distances between adjacent pins of digital tubes of different sizes are not the same; therefore, the existing equipment cannot use conventional vibration disks to transport digital tubes for inspection or conveyor belts (there are inconsistent and irregular conveying surfaces when transporting digital tubes), etc., and manual feeding and manual unloading are required after the inspection, etc., and there is no dedicated automatic feeding and unloading operation; such semi-automatic inspection equipment needs to be equipped with at least one operator for long-term operation, resulting in low inspection efficiency and difficulty in improving production speed and production efficiency. (2) When manual visual inspection is used, certain defects during the manual inspection process can cause visual fatigue and lead to many misjudgments. (3) Manual inspection is easily interfered by the outside world, and inspection efficiency cannot be guaranteed. (4) During manual inspection, each operator has different judgments on defects, which are mainly based on visual inspection, making it difficult to form quantifiable quality standards. (5) When manual inspection and semi-automatic inspection equipment are used for inspection, the digital tubes are in contact with human hands, and some impurities may be mixed into the digital tubes during inspection. (6) The labor cost of manual inspection is expensive. Under the current circumstances, it is difficult to recruit workers, and the quality of manual inspection is unstable.

[0003] Therefore, it is necessary to make certain improvements to the existing digital tube appearance inspection method to improve the problems of the prior art. Summary of the invention
