Description

Technical Field

[0002] A digital tube, also known as a glow tube, is an electronic device that can display numbers and other information. The glass tube includes an anode made of a metal mesh and multiple cathodes. Most digital tube cathodes are in the shape of numbers. The tube is filled with low-pressure gas, usually mostly neon plus some mercury and / or argon. When one of the cathodes is charged, the digital tube will emit colored light, depending on the gas in the tube, usually orange or green.

[0003] In the production process of digital tubes, it is often necessary to deal with burrs, which may affect the quality and performance of the product. For example, the Chinese patent with publication number CN220446022U discloses a deburring device for LED digital tubes, including a clamping mechanism for clamping a rotating plastic tube, a grinding mechanism for grinding burrs on the plastic tube, and a support table for supporting the clamping mechanism and the grinding mechanism, and also includes a negative pressure device, which is arranged on the grinding mechanism to collect burrs generated by the grinding mechanism when grinding the plastic tube.
