Description

Technical Field

[0001] The utility model relates to the technical field of graphitization of negative electrode materials, in particular to an automatic positioning device for loading a graphitization crucible. Background Art

[0002] With the rise of new energy, lithium batteries have been increasingly recognized by the market. In the preparation process of lithium batteries, the powder used as the negative electrode material needs to be filled into the crucible after mixing, and then the crucible is heated and calcined to finally obtain the primary finished powder used as the negative electrode material of the lithium battery. When adding the negative electrode material to the crucible, it is necessary to ensure that the crucible is aligned with the feeding port of the loader. Therefore, we launched an automatic positioning device for graphitized crucible charging.

[0003] The prior art has the following problems: 1. When the existing crucible is loaded, the crucible is directly moved to the bottom of the loader by a conveyor belt. However, when the crucible is placed on the conveyor belt, the position is not completely uniform, and deviations are inevitable. During loading, leakage may occur due to the deviation, causing waste; 2. When the existing crucible is loaded, the powder falls directly into the crucible, but the amount of powder falling each time is difficult to control, resulting in an uneven amount of powder in each crucible.

[0015] In the utility model, a rotating disk is driven to rotate in an outer shell by a second motor. When the material transport cavity of the rotating disk rotates to below the top hole of the outer shell, the powder in the hopper will drop down under the action of gravity to fill the material transport cavity, and as the rotating disk rotates, the powder is transported in the outer shell. When the material transport cavity filled with powder rotates to the hole just below the outer shell, the powder in the material transport cavity will fall into the crucible, completing the filling. This filling method can achieve uniform charging. BRIEF DESCRIPTION OF THE DRAWINGS
