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

Abstract

The invention relates to a spiral lamp top-mounted sealing clamping device and the sealing process, and is characterized in that the invention adopts a movable clamp piece to be arranged on a right clamp piece, a left clamp piece and the right clamp piece are respectively arranged on a sliding track component; a plate-shaped slot cam is arranged on an arc-shaped support plate, a rotating arm is sheathed on a support shaft, the sliding track component is fixed on two vertical poles, the vertical poles are fixed on a rotary T-shaped shaft, a hafu clamp is arranged on the rotating arm, an ascending and descending shaft is linked with a main shaft, and the rotary T-shaped shaft is arranged in a rotary component. A spiral glass lamp tube of the invention is arranged below a sealing fire source, the lamp tube foot is upward; a lamp wire core pole is inserted from the upper part of the spiral glass lamp tube, the spiral glass lamp tube and the lamp wire core pole are fused by flame heating. The clamping of the spiral glass lamp tube is stable and reliable, which can reduce the high temperature heat amount at the tube foot to the maximum extent and fundamentally solve the defects of the traditional sealing mode and the phenomena of cold explosion of the glass tube and the gas leakage which are difficult to overcome.

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 accompanying drawing 5), there are many disadvantages in this traditional sealing process: because the tube pin of spiral lamp is too short, it is easy to cause bursting at the bend of the glass tube during sealing, cold burst and uneven thickness of the material at the sealing place, which is easy to generate stress, resulting in When it enters the subsequent process, it bursts or leaks again, and 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.
