DEVICE FOR AND METHOD OF DETERMINING WHETHER OR NOT ELECTRODE TAB IS BENT - A simplified explanation of the abstract
This abstract first appeared for US patent application 17730766 titled 'DEVICE FOR AND METHOD OF DETERMINING WHETHER OR NOT ELECTRODE TAB IS BENT
Simplified Explanation
The patent application describes a device designed to determine whether electrode tabs in an electrode assembly are bent. The device includes several components such as a nesting portion, an electrode tab contact portion, a weight measurement unit, and a determination unit.
- The stably nesting portion is where the electrode assembly is placed securely.
- The electrode tab contact portion is located on the side of the nesting portion and can move downward to make contact with one end of an electrode tab. It can bend the tab and then restore it to its original state.
- The weight measurement unit is positioned above the nesting portion and measures the weight of the elastically restored electrode tab on a per-area basis.
- The determination unit analyzes the weight measurement data to determine whether the electrode tab is bent, based on the specific area where the weight is measured.
Potential applications of this technology:
- Battery manufacturing: This device can be used in the production of batteries to ensure the electrode tabs are not bent, which could affect the performance and reliability of the battery.
- Quality control: The device can be utilized as part of quality control processes in various industries where bent electrode tabs may cause issues in the final product.
- Research and development: Researchers and scientists working on electrode assembly improvements can use this device to assess the impact of different factors on the bending of electrode tabs.
Problems solved by this technology:
- Accurate detection: The device provides a reliable and objective method to determine whether electrode tabs are bent, eliminating the need for subjective visual inspection.
- Efficiency: The automated process of the device allows for quick and efficient detection of bent electrode tabs, reducing the time and effort required for manual inspection.
- Consistency: By using a standardized measurement method, the device ensures consistent and repeatable results in determining the bending of electrode tabs.
Benefits of this technology:
- Improved product quality: By detecting and preventing bent electrode tabs, the device helps to ensure the production of high-quality products with optimal performance.
- Cost savings: Early detection of bent electrode tabs can prevent the assembly of faulty batteries or other products, reducing the costs associated with rework or customer returns.
- Time efficiency: The automated nature of the device allows for faster inspection and detection, saving time in the production process.
Original Abstract Submitted
A device for detemining whether or not positive and negative electrode tabs constituting an electrode assembly are bent includes: a stably nesting portion in which the electrode assembly is stably nested; an electrode tab contact portion arranged on a side surface of the stably nesting portion and configured to move downward so as to come into contact with one end portion of an electrode tab, bending the electrode tab, and to elastically restore the electrode tab to an original state thereof; a weight measurement unit arranged above the stably nesting portion and configured to measure, on a per-area basis, a weight of the electrode tab that is elastically restored to an original state thereof; and a determination unit configured to determine whether or not the electrode tab is bent, depending on an area where the weight is measured.
