Technique for producing bulbs

Abstract

Comparing with technique for fabricating bulbs, the invention improves on following procedures: structure of sealing flame in use for technique of laying off exhaust pipe in stem and sealing step; adjusting arrangement of flame; rearranging vacuum system in use for exhaust process; technique of soldering tin in baking and assembling processes. Advantages are: increasing quality and acceptability of bulbs, prolonging service life of bulbs and lowering production cost.

Description

(1) Technical field: [0001] The invention relates to the whole process production process from core pillar manufacture to baking in the production process of ordinary lighting bulbs. (two), background technology: [0002] The production process of the light bulb comprises the following steps: making core pillars, stretching filaments, sealing, exhausting and baking. In the traditional manufacturing process of the core column, the method of lowering the exhaust rod is to use the external pressure pressing method, that is, after the exhaust rod is cut on the exhaust rod part of the core column machine, due to the splitting jaw of the original core column machine head 1. The distance between the horn jaws and the exhaust rod jaws is very small, and the exhaust rod must be pressed down to the predetermined position by an external manipulator, which will easily cause the exhaust rod to be broken or the exhaust rod port to be crushed; When the low-pressure wind is used, the low-p...

In the traditional manufacturing process of the core column, the method of lowering the exhaust rod is to use the external pressure pressing method, that is, after the exhaust rod is cut on the exhaust rod part of the core column machine, due to the splitting jaw of the original core column machine head 1. The distance between the horn jaws and the exhaust rod jaws is very small, and the exhaust rod must be pressed down to the predetermined position by an external manipulator, which will easily cause the exhaust rod to be broken or the exhaust rod port to be crushed; When the low-pressure wind is used, the low-pressure wind uses the untreated wind from the fan. The temperature of this wind varies with the temperature. Affected the qualified rate of core column production

In the process of bending the molybdenum wire hook for stretching, the filament is sent to the molybdenum wire hook at the same time as the molybdenum wire hook is bent. The traditional method is to use the puller to pull the filament into the molybdenum wire hook. Hook gear internal constriction

When sealing the bulb, the traditional sealing is to directly install the purchased torch on the sealing machine without any modification. During the flame configuration process, it is generally difficult for the flame to reach the melting temperature of the glass seal. To melt the...
