Description

Crucible Quality Management System {Sagger Quality Management System} The present disclosure relates to a crucible quality control system. The four major components of a secondary battery are commonly referred to as the cathode, anode, electrolyte, and separator. Among these, the cathode, anode, and separator are considered core materials because they determine the overall performance of the secondary battery. Secondary batteries, such as lithium-ion batteries, generally generate electricity through the chemical reaction of lithium ions moving between the cathode and the anode. Here, while the cathode determines the overall capacity and voltage of the battery, the anode plays the role of storing and releasing lithium ions from the cathode. The processing of such battery materials may include a firing process in which the material is placed in a kiln and heated. This firing process can be carried out by placing the material into a crucible and then placing the crucible into the kiln. Since the firing process is performed at high temperatures, cracks may occur or the crucible may oxidize during use. Consequently, there is a risk that reused crucibles may be damaged during the firing process, which leads to material loss and reduced process efficiency. Therefore, the degree of cracking and oxidation of the crucible needs to be managed before reuse. FIG. 1 is a drawing showing a crucible quality control system according to one embodiment.

FIG. 15 is a drawing showing a crucible inspection device according to another embodiment. Hereinafter, various 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 present invention. The present invention may be embodied in various different forms and is not limited to the embodiments described herein. To clearly explain the present invention, parts unrelated to the explanation have been omitted, and the same reference numerals are used for identical or similar components throughout the specification. Furthermore, the size and thickness of each component shown in the drawings are depicted arbitrarily for convenience of explanation, and thus the present invention is not necessarily limited to what is illustrated. Thicknesses have been enlarged in the drawings to clearly represent various layers and regions. Additionally, for convenience of explanation, the thickness of some layers and regions has been exaggerated in the drawings. 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. Furthermore, throughout the specification, when a part is described as "including" a certain component, this means that, unless specifically stated otherwise, it does not exclude other components but may include additional 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.
