Embodiment Construction

[0051] A system and method for manufacturing a light bulb according to one embodiment of the present invention will now be described with reference to the accompanying drawings.

[0052] image 3 is a flowchart of a method of manufacturing a light bulb according to one embodiment of the present invention.

[0053] A method of manufacturing a light bulb according to an embodiment of the present invention includes forming a flare in step S10, performing separation of the bulb material tube in step S20, forming a dome in step S30, supplying the bulb material tube in step S40, and Lower heating is performed in step S50, and blow molding is performed in step S60.

[0054] In the flare forming step S10, both ends of the glass tube 21 having a predetermined length are heated and then pressure is applied to both ends of the glass tube 21 to form flares with enlarged diameters on both ends. In other words, in the flaring step S10, both ends of the glass tube 21 having a predetermined...

Abstract

The present invention relates to a method and system for manufacturing a bulb. More particularly, the present invention relates to a method and system for manufacturing a bulb in which a flare and a dome are formed on both ends of a glass tube to thereby manufacture a bulb material tube, and a lower portion of the bulb material tube is heated and a blowing process is performed in a mold such that waste of the glass tube is prevented. A method for manufacturing a bulb, comprising: heating both ends of a glass tube of a predetermined length, then applying a pressure to both ends of the glass tube to form flares of an enlarged diameter on both ends; heating a center portion of the glass tube with flares formed at both end thereof while being rotated at a predetermined speed, and, at the same time, applying a force in the direction of both ends such that the separated center portion is closed off to form two closed off bulb material tubes; heating a lower portion of the bulb material tube while rotating the same; and performing blow forming by rotating the heated bulb material tube in a state where its lower portion is positioned in a mold, and injecting a gas in the bulb material tube through its flare to thereby form a bulb. The system for manufacturing a bulb includes a flare forming device, a bulb material tube separating device, and a blow forming device.

Description

technical field [0001] The present invention relates to a method and system for manufacturing a light bulb. More particularly, the present invention relates to such a method and system for manufacturing a light bulb by providing a bulb material tube with flares and domes formed on both ends thereof, heating the lower portion of the bulb material tube, and heating the bulb material tube Air is blown to form the bulb in the mold, preventing wastage of bulb material. Background technique [0002] Small containers such as glass bottles or ampoules and light bulbs are often manufactured by heating and sealing one end of the glass tube material, and then by performing a blowing process on this area in a predetermined mold. This method of manufacturing a bulb from glass tube material has been described in Japanese Patent Publication No. Showa 52-31584 entitled "Method for Making Glass Tube Flare", Japanese Patent Publication No. Showa 52-31584 entitled "Manufacturing Method of Gla...
