A kind of manufacturing method of bluetooth earphone battery

Abstract

A method for manufacturing a Bluetooth earphone battery, comprising the following steps: S1: preparing a core pack; S2: putting the core pack in a drying room for baking, and the drying room includes a drying room area A, a liquid injection room A area, Air shower room and operation assembly area; S3: After the core package is baked in the oven, it enters the drying room A area through the oven, and the baked core package and the sealing cover are fitted in the drying room A area; S4: sleeve The combined core package enters the injection chamber A area through the transfer box, and uses operating gloves in the operation assembly area to impregnate the packaged core package and the sealing cover in the electrolyte; S5: put the impregnated core package and the sealing cover Put it in an aluminum shell, complete the sealing by a sealing machine, and prepare the bluetooth earphone battery. The invention can avoid the problem that the battery core pack absorbs water again during the processing process, improves the production efficiency, and the prepared bluetooth earphone battery has good charging and discharging performance and long service life.

Description

technical field [0001] The invention relates to the field of batteries, in particular to a method for manufacturing a Bluetooth earphone battery. Background technique [0002] Bluetooth headset is a small device based on Bluetooth technology. You only need to hide this lightweight device beside the headset without directly using communication devices (mobile phones, computers, etc.) to realize free calls. Bluetooth headset is to apply Bluetooth technology to hands-free headsets, so that users can avoid annoying wires and talk easily in various ways. Since the advent of Bluetooth headsets, it has been a good tool for business people to improve communication efficiency. [0003] During the production process of the Bluetooth headset battery, it is necessary to dry the battery pack to ensure that the moisture contained in the battery pack is controlled within a certain range before proceeding to the next step. Moisture has a great impact on the performance of Bluetooth batter...

AI Technical Summary

Problems solved by technology

Moisture has a great impact on the performance of Bluetooth batteries. At this stage, Bluetooth headset batteries can only tolerate water content below 100ppm. When the moisture in the battery exceeds the standard, the battery will have problems such as low capacity, flatulence, high internal resistance, and reduced cycle life. Therefore, the control of moisture is particularly strict in the production process of Bluetooth headset batteries

After the Bluetooth headset battery is dried, follow-up operations are required. During the transfer and storage of the battery pack, the battery pack absorbs moisture in the air, causing secondary pollution and increasing the moisture in the battery.

[0004] The biggest problem of the Bluetooth headsets on the market is still the battery life. The battery charging time is long, but the charging current of the battery fast charging is large, reaching 100 mA. The original pin-type Bluetooth headset batteries use a pair of lead strips as positive and negative. Extreme output, can not withstand high current impact for a long time, it is easy to cause internal heating, rapid capacity drop, product failure and other problems
