Abstract

The invention relates to a processing process of a lamp tube with high switching frequency and a processing apparatus thereof. The processing process includes following steps: (1) putting filaments ofthe lamp tube into a paste tank for performing coating of electronic paste, and electrifying the paste; and (2) putting the processed filaments of the lamp tube in step (1) on a hot air blowing device for hot air blowing processing, and drying electronic powder on the filaments of the lamp tube. The processing apparatus comprises the hot air blowing device, the hot air blowing device comprises acylindrical shell with a cavity and heating wires located in the cavity of the cylindrical shell, an air-outlet pipe is arranged at the top of the cylindrical shell, an air-inlet pipe is arranged at the bottom of the cylindrical shell, and the air-inlet pipe is connected with a fan. According to the processing process and the processing apparatus, the electronic paste is coated on the filaments ofthe lamp tube, wet electronic powder on the filaments is immediately blown by hot air through the hot air blowing device, the drying speed of the electronic powder is accelerated, the switching frequency of the lamp tube is greatly increased by twice, the switching frequency can generally reach about 12000 times, and the internal quality of the lamp tube is substantially improved.

Description

technical field

[0001] The invention relates to the field of lamp tube preparation, in particular to a processing technology and processing equipment for a high switching times lamp tube. Background technique

[0002] During the preparation process of the filament in the lamp tube, the filament part needs to be coated with electronic powder, and the coating of the electronic powder directly affects the switching times of the lamp tube.

[0003] For example, the Chinese patent No. 201610409911.9 discloses a processing technology for stretching filaments of fluorescent lamps. It is characterized in that the processing steps are: Step 1. Material preparation: several groups of filaments with different specifications are selected; the weight of electronic powder is 4.0 ±0.5; nickel-plated iron strip 5.0*0.2; step 2, filament heating: open the electrical switch, heater and powder blowing switch, heat the machinery and workpieces to be processed, step 3, stretching wire processing...
