Glass lamp tube processing technology

Abstract

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.

Description

technical field [0001] The invention relates to the field of glass lamp tube production, in particular to a glass lamp tube processing technology with high qualified rate of finished products and high light transmittance of the glass lamp tube. Background technique [0002] Incandescent and fluorescent tubes are traditional lighting fixtures. In recent years, LED lamps have attracted much attention because of their energy saving, environmental protection, small size, and long life. LED lamps are replacing traditional incandescent lamps and fluorescent tubes as mainstream lighting lamps. At present, the tube body of the fluorescent tube is mainly a glass tube, and it is also possible to use plastic to make the tube body of the fluorescent tube. LED lamps include tubular LED lamps and the like. The body of the LED light tube is generally made of plastic, such as polycarbonate (PC). Whether it is the plastic tube body of the LED lamp tube or the plastic tube body that may be...

AI Technical Summary

Problems solved by technology

At present, the extrusion molding process is used to make the lamp tube body. One is slow, takes a long time, and has low production capacity. The two have not established a standardized and complete production process. The deployment of raw materials and the transition between the upper and lower processes are not smooth Coordinated, unable to maximize production capacity, limited by this, the qualified rate of finished products produced is also low, especially the subsequent head-on process is likely to have an impact on the glass lamp tubes that have been powder-coated, causing the inside of the glass lamp tubes to The vibration variation of the powder coating film affects the light transmittance of the glass lamp tube
