Glass lamp tube processing technology

The invention discloses a glass lamp tube processing technology. The technology comprises the following steps of tube cutting and burring, tube bending, pin bending / pin cutting / burring, annealing, exposed tube film coating and powder coating, head lathing, tube baking, powder rubbing and port sealing. Main inspection procedures are arranged after head lathing. When internal powder coating of the exposed tube after head lathing is disqualified through inspection, tube washing or scrapping is performed according to different orders of severity. For example, tube washing is performed if the order of severity is within the repairable scope, then powder distribution is performed again and film coating and powder coating are performed on the repair tube again, the process enters the tube baking procedure and powder rubbing is performed after qualification is proved through inspection, and then wire stretching and port sealing are performed on the lamp tube. A complete production technology procedure is established, all procedures of use of a straight tube, manufacturing of the exposed tube and final completion of the finished lamp tube are coordinated compactly and coherently so that production efficiency of the glass lamp tube is enhanced. Generation of defective products can be eliminated by the inspection procedures arranged between up and down processes, and product percent of pass and transmittance of the glass lamp tube can be substantially enhanced.
