AI Technical Summary

Problems solved by technology

In the existing step of upper stem / automatic wire binding, the light source will not be treated differently in different temperature environments. Because the performance of the light source in different temperature environments is different, there may be wrong circuit breaker protection at high temperature
Moreover, there is no driving circuit to adjust or calibrate the power of the light source in the upper stem / automatic wire binding step of the existing technology
The tube diameter produced by this process is small, so if the tube length is too long, high-power tubes cannot be realized.

Embodiment Construction

[0016] The present invention is further described below in conjunction with embodiment:

[0017] A technological method for making lamp tubes, the technological process of which is pipe cutting → pipe bending → bridging → pipe cleaning → roasting pipe → powder coating → powder baking → wiping head → upper stem / filling → exhaust → sealing → pointing Bright calibration→aging→packaging, the above stem / filling process includes wire loading→welding→electronic layer coating→stem loading→sorting.

[0018] A kind of technological method for making the lamp tube provided by the invention can manufacture the high-power lamp tube with smaller tube diameter and longer tube length.

[0019] The diameter of the lamp tube used in the tube cutting step can reach below 1.4 cm, and the unit tube length can reach 22 cm.

[0020] A high temperature parabola is used for bending in the tube bending step.

[0021] In the powder coating step, when carried out under high temperature conditions, solu...

Abstract

The invention provides a technical method for manufacturing a light tube. The technical procedure comprises the steps of tube cutting, tube bending, bridge connection, tube cleaning, tube baking, powder coating, powder baking, head rubbing, stem installation / injection, gas discharge, opening sealing, lightening and marking, aging and packaging. The technical method for manufacturing the light tube is characterized in that the stem installation / injection technology comprises the steps of filament installation, butt-welding, electronic shell coating, stem installation and separation. By means of the technical method for manufacturing the light tube, a high-power light with the small tube diameter and the large length can be manufactured.

Description

technical field [0001] The invention relates to a process method, in particular to a process method for making a lamp tube. Background technique [0002] At present, there are many processes for making lamp tubes. The common process methods are tube cutting→bending→powdering→baking tube→powdering→sealing→bridging→exhausting. The upper stem can be added in the steps of powdering and sealing. / Automatic wire binding step. In the existing stem loading / automatic wire binding step, the light source will not be treated differently in different temperature environments. Because the performance of the light source in different temperature environments is different, there may be wrong circuit breaker protection at high temperature. Moreover, there is no driving circuit to adjust or calibrate the power of the light source in the step of loading stem / automatic wire binding in the existing technology. The process produces smaller tube diameters, so high power tubes cannot be achieved ...
