Description

Crucible Automatic Raw Material Filling System The present disclosure relates to an automatic filling system for crucible raw materials. Artificial graphite is widely used in fields such as negative electrode materials for secondary batteries, electrode rods for iron and steelmaking, electrodes for electrical discharge machining, nuclear fusion reactors, semiconductors, and solar cells. Although such artificial graphite has the disadvantages of a lower degree of graphitization and a higher price due to manufacturing process costs compared to natural graphite, it is gaining attention as an anode material for secondary batteries due to its relatively superior lifespan characteristics. Generally, artificial graphite is produced by stacking crucibles filled with raw materials for artificial graphite production inside a graphitization furnace, filling the spaces between them with a filler so that the crucibles are embedded, and then indirectly heating the crucibles with resistance heat generated therefrom by passing an electric current to graphitize the raw materials inside the crucibles. In the conventional process of filling raw materials into a crucible, the lid of the crucible is removed using a robotic arm and the raw materials are injected using a filling pipe. However, due to faulty sensing, collisions between the robotic arm and the crucible occur, causing equipment damage or scattering of raw materials, which contaminates the working environment.

FIG. 2 is a partially enlarged perspective view of an automatic crucible raw material filling system according to one embodiment.

Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings so that those skilled in the art can easily implement the invention. In order to clearly explain the invention in the drawings, parts unrelated to the explanation have been omitted, and the same reference numerals have been used for identical or similar components throughout the specification. Furthermore, in the attached drawings, some components may be exaggerated, omitted, or schematically depicted, and the size of each component does not entirely reflect its actual size. The attached drawings are intended only to facilitate understanding of the embodiments disclosed in this specification, and the technical concept disclosed in this specification is not limited by the attached drawings; it should be understood that all modifications, equivalents, and substitutions included within the concept and technical scope of the present invention are included. Terms including ordinal numbers, such as first, second, etc., may be used to describe various components, but said components are not limited by said terms. These terms are used solely for the purpose of distinguishing one component from another. Furthermore, when it is said that a part, such as a layer, membrane, region, or plate, is "on" or "on" another part, this includes not only the case where it is "directly above" the other part, but also the case where there is another part in between. Conversely, when it is said that a part is "directly above" another part, it means that there is no other part in between. Also, saying that a part is "on" or "on" a reference part means that it is located above or below the reference part, and does not necessarily mean that it is located "on" or "on" in the direction opposite to gravity. Throughout the specification, terms such as “comprising” or “having” are intended to indicate the existence of the features, numbers, steps, actions, components, parts, or combinations thereof described in the specification, and should be understood as not precluding the existence or addition of one or more other features, numbers, steps, actions, components, parts, or combinations thereof. Accordingly, when a part is said to “comprising” a certain component, unless specifically stated otherwise, this means that it may include additional components rather than excluding other components. Additionally, throughout the specification, "planar" means when the subject part is viewed from above, and "cross-sectional" means when the cross-section obtained by vertically cutting the subject part is viewed from the side. Throughout the specification, when a part is described as being "coupled" with another part, this includes not only cases where they are "direc
