Apparatus and prcoess for filling mercury into fluorescent tubes by circular arranging trolley

Abstract

In this invention, the new technology and apparatus are applied for the fluorescence lamp producing. Before infusing mercury into the fluorescence lamp, the vent pipe is fixed, putting the mercury drop on the frame, turning off the vacuum switch, tightening the locking nut, the inflate hole of the movable tray is connected with the fix tray's. Turning on the vacuum pump to pump the vent pipe and luminous tube to the status of vacuum, upon completion, disconnect the inflate holes of the movable tray and fix tray. Turning off the vacuum switch, the mercury drop and inert gases enter the vent pipe and luminous tube, thus the mercury infusion of the luminous tube is achieved.

Description

technical field [0001] The invention relates to a technique for injecting mercury into lamp tubes on a circular row car in the production process of fluorescent lamps and a device used for an injection pump. Background technique [0002] In the production process of fluorescent lamps, it is a very important task to inject mercury into the lamp tubes by the round row car. It is necessary to control the amount of mercury injection and not to cause harm to human body and environment. At present, because the inner diameter of the exhaust pipe directly connected to the lamp tube is large, it is very easy for mercury to fall into the lamp tube from the exhaust pipe by gravity. Even if the exhaust pipe pollution occurs, the pipe is loose and For mercury injection accidents such as rubber bead damage, the requirements can also be achieved by manually injecting mercury multiple times; however, the amount of mercury injected into the lamp tube by this mercury injection method is uneve...

AI Technical Summary

Problems solved by technology

At present, because the inner diameter of the exhaust pipe directly connected to the lamp tube is large, it is very easy for mercury to fall into the lamp tube from the exhaust pipe by gravity. Even if the exhaust pipe pollution occurs, the pipe is loose and For mercury injection accidents such as rubber bead damage, the requirements can also be achieved by manually injecting mercury multiple times; however, the amount of mercury injected into the lamp tube by this method of mercury injection is uneven, and the amount of mercury in each lamp tube varies greatly. Large, not only affects the luminous flux and service life of each lamp, but also causes waste of mercury and environmental pollution

With the vigorous development of energy-saving lamps, the diameter of the exhaust pipe is also large and small; due to environmental protection requirements, the amount of mercury injected into the fluorescent lamp tube must also be strictly controlled, so it has a great impact on the production process of the circular car.
