Process for producing enclosed halogen tungsten automobile headlight

Abstract

The invention discloses a process for producing an enclosed halogen tungsten automobile headlight, which comprises the following steps: (1) carrying out racking; (2) carrying out buttwelding, namely melting and butting two ends of a copper pin and a molybdenum pin through power supplying to form a copper-molybdenum pin; (3) carrying out spot welding of molybdenum plates, namely respectively performing spot welding between the one end of each of three molybdenum plates and each of three molybdenum rods on a light stand, and between the other ends of the three molybdenum plates and three copper-molybdenum pins; (4) after completing the manufacture of a wick and a glass bulb, carrying out press seal, and reserving an air exhaust rod at the upper end of the glass bulb; (5) performing hydrogenbrightening and air exhausting, namely completing the hydrogen brightening and air exhausting on a round exhaust machine together; (6) bending the copper-molybdenum pins after stable power-on burn-indetection; and (7) after completing manufacturing a lamp base, carrying out focusing assembly, carrying out surface covering, displacing gas in an inner cavity of the halogen tungsten automobile headlight, carrying out leak detection process, and carrying out finished production inspection after the leak detection process. The process can reduce rejection rate, has simple and convenient operationand high work efficiency.

Description

technical field [0001] The invention relates to a production process of a closed-type tungsten-halogen automobile headlamp. Background technique [0002] At present, the existing closed-type tungsten-halogen automotive headlamp production process usually includes the following processes: [0003] Material selection: select the filament, make the lamp holder and molybdenum sheet, and the lamp holder includes three molybdenum rods and quartz glass rods fused and pressed on the molybdenum rods; [0004] Mounting: welding the filament to the lamp frame; [0005] Spot welding of molybdenum sheets: one end of the three molybdenum sheets is spot welded to the three molybdenum rods on the lamp stand, and the other end of the three molybdenum sheets is spot welded to the three molybdenum feet respectively; [0006] After the wick and glass bulb are made, press seal, and keep the exhaust rod at the upper end of the glass bulb to make a semi-finished hair bubble: press seal the wick ...

AI Technical Summary

Problems solved by technology

[0012] In order to overcome the major quality hazards caused by the poor spot welding performance of molybdenum feet and copper feet in the existing production process of closed halogen tungsten automobile headlights; and the instability of product quality, high scrap rate and troublesome operation caused by manual bending of molybdenum feet , low work efficiency; there are two procedures for bright hydrogen and exhaust, troublesome operation and low work efficiency; there are also many hair bubbles that are not bright and missed in the aging process after exhaust. phenomenon; the present invention provides a closed-type tungsten-halogen automotive headlight production process that can completely eliminate hidden dangers, improve product quality, reduce scrap rate, easy operation and high work efficiency
