Technical Field

[0001] This utility model relates to a glass rod heating device, belonging to the field of glass rod heating technology. Background Technology

[0002] Optical glass lenses are transparent media composed of two refractive surfaces, also known as lenses. They provide clear images, are resistant to scratches, and can absorb some ultraviolet rays. Different materials have different characteristics in terms of UV resistance, scratch resistance, and image quality. Currently, the production process for optical glass lenses involves first selecting a glass rod of appropriate material according to actual requirements, then cutting the glass rod into segments. These segments are then heated at high temperatures to soften them. The softened glass rods are then extruded to form glass lens blanks, which are subsequently ground to create the final optical glass lens.

[0003] Heating the glass rod is a crucial step in the process described above. Currently, there are various types of equipment for heating glass rods. For example, there is a Chinese utility model patent with authorization announcement number CN216141457 U and patent name: Glass Softening Furnace for Optical Components. In this patent, after the threaded sleeve moves forward and comes into close contact with the movable sleeve, the threaded sleeve stops moving forward. At this point, the glass rod will be pushed forward, and the user can easily remove the remaining glass rod without risking burns. This convenient method solves the problem of inconvenient removal of finished products in existing glass softening furnaces for optical components.
