An upper laid sealing and fixture device for spiral lamp and the corresponding sealing techniques

Abstract

The invention relates to a top-mounted sealing fixture device for a spiral lamp and its sealing process, which is characterized in that the movable clamp is installed on the right clamp, and the left clamp and the right clamp are respectively installed on the slide rail assembly; the plate shape The grooved cam is installed on the arc-shaped support plate, the rotating arm is set on the supporting shaft, the slide rail assembly is fixed on the two vertical rods, the vertical rod is fixed on the rotating T-shaped shaft, the Huff clamp is installed on the rotating arm, and the lifting shaft Coupled with the main shaft, the rotating T-shaped shaft is installed in the rotating assembly. The spiral glass lamp tube of the present invention is placed under the sealed fire source, and the lamp tube pins are upward; the filament stem is inserted from the upper part of the spiral glass lamp tube, heated by flames, and the spiral glass lamp tube and the filament stem are fused. The clamping of the spiral glass lamp tube is stable and reliable, which minimizes the high temperature heat at the tube pins, and fundamentally solves the defects of the traditional sealing method and the insurmountable cold burst and air leakage of the glass tube.

Description

technical field [0001] The invention relates to an upper-mounted sealing fixture device for a spiral lamp and a sealing process thereof, specifically belonging to the technical field of lamp processing. Background technique [0002] With the continuous progress of human society, energy conservation and environmental protection are highly valued by people. As a new type of energy-saving and environmentally friendly product, my country's compact energy-saving lamp light source has developed rapidly under the active promotion of governments at all levels. Spiral energy-saving lamps are quickly accepted by the market due to their small size, high power, high brightness, and beautiful appearance. The development prospects are broad and the market demand is constantly expanding. It is imminent and urgent to implement the large-scale production of this product with mechanical automation. [0003] The bottom-mounted sealing fixture of the spiral lamp is composed of a glass tube fi...

AI Technical Summary

Problems solved by technology

(see attached Figure 5 ), the traditional sealing process has many disadvantages: due to the short leg of the spiral lamp, it is easy to cause bursting at the bend of the glass tube during sealing, cold burst and uneven thickness of the sealing material, which is easy to generate stress, resulting in the subsequent process. Explosion or air leakage again, the product qualification rate is greatly reduced

The existing sealing technology in the industry adopts the bottom sealing method. The above-mentioned bursting phenomenon is difficult to eliminate, and the proportion of bursting is very high, and the production cost is increased, which hinders the popularization and promotion of the spiral lamp.
