Description

Technical Field

[0002] Lamp tubes are a common lighting equipment, mainly including fluorescent tubes, LED tubes, halogen tubes, high-pressure sodium lamps and low-pressure sodium lamps. They are widely used in homes, offices, shops, factories and other places, as well as in automobiles and other fields. Among them, fluorescent tubes are the most common type of lamp tubes. They use gas discharge to generate ultraviolet rays, which are then converted into visible light through phosphors. They have the advantages of high energy efficiency, long life, and a variety of color temperature options. They can be widely used in commercial lighting and industrial lighting.

[0003] During the processing and production of fluorescent tubes, it is necessary to evenly spray a kind of fluorescent powder on the inner wall, and then send it to the drying workshop for drying. Traditionally, the fluorescent tubes are sprayed on the inner wall by manually placing the fluorescent tubes vertically on the racks, and then the fluorescent tubes are automatically transferred to the spraying workshop, where the inner wall of the fluorescent tubes is sprayed with a sprayer.

[0058] After the lamp tube is sprayed, it continues to be transported to the drying chamber 5 for drying. After the drying is completed, it is moved out of the drying chamber 5 and moved to the guide tube mechanism 6;

[0059] The positioning member 25 first passes through the third rack 28, and the third rack 28 is meshed with the first gear 2533 in the positioning member 25. The third rack 28 drives the first gear 2533 to rotate in the opposite direction, driving the driving worm 2532 to drive the driven worm gear 2531 to rotate in the opposite direction, thereby controlling one of the flip shafts 253 to rotate in the opposite direction, and further driving the positioning horizontal frame 254 and the positioned lamp tube to rotate 90 degrees in the opposite direction to reset;

[0060] The positioning member 25 then passes through the fourth rack 29, and the fourth rack 29 is meshed with the third gear 2554 in the positioning member 25, and the fourth rack 29 drives the third gear 2554 to rotate in the opposite direction, driving the driving longitudinal shaft 2553 and the second gear 2552 to rotate in the opposite direction, and then driving the crown gear 2551 and the double-headed screw 255 to rotate in the opposite direction, thereby controlling the positioning slides 256 and the positioning frames 257 on both sides to move in opposite directions, and the lamp tube loses its clamping and automatically falls on the two guide plates 62 for automatic unloading and guiding, which is convenient for subsequent processing of the lamp tube.

[0061] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
