Problems solved by technology

[0002] With the improvement of living standards, people have relatively high requirements for daily lighting. At the same time of lighting, they also need relatively high processing requirements for fluorescent lamps. Fluorescent lamps generally refer to light-emitting diodes, especially when sealing fluorescent tubes. Due to the lack of temperature during the sealing process heating and sealing, and the unreasonable control of the fire head, the seal has uneven thickness, leaks and cracks. The wire breaks, resulting in defective products and increasing production costs

Embodiment 1

[0019] A sealing process for fluorescent tubes, the sealing process steps are:

[0020] (1) The lamp tube is preheated. Turn on the electrical switch to preheat the lamp tube. During preheating, the burner is set 2mm above the horn, the gas flow of the burner is large, the low-pressure air flow is small, and the flame is weak.

[0021] (2) The lamp tube is sealed and heated, and the preheated lamp tube is further heated. During heating, three stages of heating are carried out, and the amount of oxygen is gradually increased during each stage of heating, and the increase rate is 1L / min. And the position of the fire head is set at 1mm above the bell mouth.

[0022] (3) Sealing and firing, the lamp tube after heating is sealed and fired, the blanking of the heated lamp tube is cut first, and then the bell mouth is burned, and a small amount of oxygen is used for burning. For air intake, the two fire heads in the middle are set on the bell mouth, and the two fire heads on the sid...

Embodiment 2

[0029] A sealing process for fluorescent tubes, the sealing process steps are:

[0030] (1) The lamp tube is preheated. Turn on the electrical switch to preheat the lamp tube. During preheating, the burner is set 2mm above the horn.

[0031] (2) The lamp tube is sealed and heated, and the preheated lamp tube is further heated. During heating, three stages of heating are carried out, and the amount of oxygen is gradually increased during each stage of heating, and the increase rate is 2L / min. And the position of the fire head is set at 1mm above the bell mouth.

[0032] (3) Sealing and firing, the lamp tube after heating is sealed and fired, the blanking of the heated lamp tube is cut first, and then the bell mouth is burned, and a small amount of oxygen is used for burning. For air intake, the two fire heads in the middle burn on the bell mouth, and the two fire heads on the side are set 1.5mm above the bell mouth.

[0033] (4) Annealing treatment: cool down the sealed and f...

Abstract

The purpose of the invention is to provide a fluorescent lamp tube sealing process comprising the following steps: (1) lamp tube preheating; (2) lamp tube seal heating; (3) seal burning: carrying out seal burning on a lamp tube after heating, cutting the blank of the lamp tube after heating, and burning the shoulder of a flared mouth; and (4) annealing treatment. The evenness of the seal is improved. The occurrence of seal leakage and rupture is reduced. The temperature is controlled reasonably to avoid seal guide wire breakage and reduce the rate of defective products.

Description

technical field [0001] The invention relates to the field of fluorescent lamp processing technology, in particular to the improvement of the sealing processing of fluorescent lamp tubes, and in particular to a fluorescent tube sealing process. Background technique [0002] With the improvement of living standards, people have relatively high requirements for daily lighting. At the same time of lighting, they also need relatively high processing requirements for fluorescent lamps. Fluorescent lamps generally refer to light-emitting diodes, especially when sealing fluorescent tubes. Due to the lack of temperature during the sealing process heating and sealing, and the unreasonable control of the fire head, the seal has uneven thickness, leaks and cracks. The wire breaks, resulting in defective products and increasing production costs. [0003] Therefore, a sealing process for fluorescent tubes is provided, in order to improve the sealing process of the lamp tubes, improve the...
