Abstract
Description
Technical Field
[0001] The utility model relates to the field of LED digital tube packaging, in particular to LED digital tube packaging equipment. Background Art
[0002] LED digital tubes are composed of multiple light-emitting diodes packaged together to form an "8"-shaped device. The leads have been connected internally, and only their individual strokes and common electrodes need to be led out. In the prior art, the digital tube is actually composed of seven light-emitting tubes forming an 8-shaped structure, plus a decimal point, which is 8. These segments are represented by letters a, b, c, d, e, f, g, dp. After the LED digital tube is assembled, the LED digital tube needs to be packaged and filled with glue, and the packaging process of the LED digital tube includes the steps of bonding, packaging material filling, curing and cutting.
[0003] When the LED digital tube is packaged and glued, the glue will be discharged through the glue discharge tube. However, when the glue filling is stopped, some glue that is not discharged in time will remain in the glue discharge tube. If it is not cleaned in time, the glue will adhere to the inner wall of the glue discharge tube and condense, causing the inside of the glue discharge tube to be blocked and the glue cannot be discharged here.
[0004] Therefore, it is necessary to invent a LED digital tube packaging device. Utility Model Content
