Problems solved by technology

[0007] However, removing the phosphors on both ends of the fluorescent lamp by physical treatment such as brushing has the disadvantage that the phosphor treatment time is too long
[0008] In addition, by physically removing the phosphor, some phosphor remains

Embodiment Construction

[0021] Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

[0022] As shown in Fig. 1, the method for removing the coating of the lamp tube according to the present invention includes: a step S100 of applying phosphor inside the fluorescent lamp G (Fig. 2) by using a coating removal device capable of forming and removing the coating; The above-mentioned coating removal device, the step S110 of immersing the end of the fluorescent lamp G coated with phosphor in the coating step S110 in a solvent; injecting dry air into the fluorescent lamp G dipped in the dipping step S110 to squeeze The solvent is removed to remove the phosphor in the coating removal step S120.

[0023] In such a fluorescent lamp coating method, the coating step S100 is performed before the fluorescent lamp G coating removal step is performed. The coating step S100 is accomplished by the coating removal device shown in FIG....

Abstract

The present invention relates to a device for removing coating layers of a light tube and a method thereof. The method for removing coating layers of a light tube comprises the steps of coating a fluorophor inside a light tube through a coating layer removing mechanism which is capable of forming and removing coating layers, dipping the end of the light tube coated with the fluorophor through the coating step into a solvent through the coating layer removing mechanism; and then injecting dry air into inside the light tube dipped in the dipping step to extrude the solvent out to remove the coating layers of the fluorophor.In the chemical treatment manner, the method for removing coating layers of light tubes is capable of effectively removing fluorophor maintained in the light tube after the coating operation.In addition, after the coating layer removing step is completed, a step of ultrasonic cleaning is executed to remove coating layers of a fluorescent lamp more effectively.

Description

technical field [0001] The invention relates to a lamp tube coating removal device and a removal method thereof, in particular to a removal device and a removal method which can effectively remove the phosphor lamp tube coating remaining after coating operation by means of chemical treatment. Background technique [0002] Generally, fluorescent lamps are divided into cold cathode fluorescent lamps (CCFL: Cold Cathode Fluorescent Lamp) and external electrode fluorescent lamps (EEFL: External Electrode Fluorescent Lamp), and such fluorescent lamps are manufactured through the following process, that is, through the glass tube used to manufacture the lamp tube The coating (coating) process of coating and hardening the phosphor inside, and the sealing (sealing) process of exhausting the gas inside the glass tube used to manufacture the lamp tube, injecting gas and mercury, and sealing it to a certain size. [0003] The fluorescent lamp is sealed after being injected with a certa...
