[0001] The present disclosure relates to a method and device for inspecting a battery header.

[0002] The battery header, installed on one side of the battery case, is manufactured to include a base for sealing the battery interior and pins that serve as electrodes. In the battery header, the base and pins must be insulated, while sealing between the base and pins is essential to prevent electrolyte leakage from the battery. Defects in the insulation and / or sealing between the base and pins can lead to not only performance issues but also the risk of accidents caused by electrical leakage or electrolyte leakage.

[0003] Accordingly, strict quality control is required during the manufacturing of battery headers through inspections of insulation, sealing, etc.

[0004] Traditionally, battery header inspection was performed manually, using sampling rather than 100% inspection. However, this conventional inspection method not only fails to filter out all defective products, but also fails to guarantee inspection accuracy due to manual inspection.

In one embodiment, the battery header inspection device (100) may separate the battery header (200) determined to be normal as a result of the inspection from the rail (150) and transport it to a collection box.

[0096] In addition, the method for inspecting a battery header (200) according to one embodiment of the present disclosure may further include a step of separating and collecting a battery header (200) that is determined to have a defective dimension, surface condition, insulation condition, or sealing condition as a result of the inspection from the rail (150). In one embodiment, the battery header inspection device (100) may classify the battery header (200) that is determined to have a defective dimension, surface condition, insulation condition, or sealing condition as a result of the inspection and transport the same to a collection bin.

[0097] Additionally, the method for inspecting a battery header (200) according to one embodiment of the present disclosure may further include a step of separating and collecting a battery header (200) requiring additional inspection from a rail (150).

[0098] Although the present disclosure has been described with specific details such as specific components and limited examples, the above examples are provided only to help a more general understanding of the present disclosure, and the present disclosure is not limited thereto, and a person having ordinary knowledge in the technical field to which the present disclosure pertains may make various modifications and variations based on this description.

[0099] Therefore, the spirit of the present disclosure should not be limited to the embodiments described above, and all modifications equivalent to or equivalent to the claims described below, as well as the claims described below, are considered to fall within the scope of the spirit of the present disclosure.
