Laser welding solution for rechargeable button cell

If you are careful enough,you can often notice there is a laser chiller unit standing beside a laser welding machine. That laser welding machine chiller serves for cooling the laser source inside so that the laser source can always be under efficient temperature control.

In the recent year, as the development of electronics, 5G technology and artificial intelligence continues, global electronics products are heading toward the trend of being more intelligent, lighter, more entertaining and so on. Smart watch, smart soundbox, true wireless stereo (TWS) bluetooth earphone and other intelligent electronics are experiencing high demand. Among those, TWS earphone is no doubt the most popular one.

TWS earphone generally consists of DSP, battery, FPC, audio controller and other components. In these components, the cost of battery accounts for the 10-20% of the total cost of the earphone. The earphone battery often uses rechargeable button cell. Rechargeable button cell is widely used in consumer electronics, computers and its accessories, communications, medical appliance, home appliance and other areas. This kind of battery cell is much harder for processing, comparing with traditional disposable button cell. Therefore, it has higher value.

In our daily life, most of the low-value electronics often uses traditional disposable (unrechargeable) button cell which is cheap and easy to process. However, as consumer requires high duration, high safety and personalization in electronics, many battery cell manufacturers turn to the rechargeable button cell. For this reason, the processing technique of the rechargeable button cell is also upgrading and traditional processing technique can not meet the standard of the rechargeable button cell. Therefore, many battery cell manufacturers begin to introduce laser welding technique.

Laser welding machine can meet the various demands of rechargeable button cell processing, such as welding dissimilar materials (stainless steel, aluminum alloy, nickle and so on) and irregular welding path. It features excellent welding appearance, stable weld joint and precise positioning welding area. Since it is non-contact during operation, it will not damage the rechargeable button cell.

If you are careful enough, you can often notice there is a laser chiller unit standing beside a laser welding machine. That laser welding machine chiller serves for cooling the laser source inside so that the laser source can always be under efficient temperature control. If you are not sure what chiller supplier to choose, you can have a try on S&A Teyu closed loop chiller.

S&A Teyu closed loop chiller is widely used for cooling different laser sources in various kinds of laser welding machines. Its cooling capacity ranges from 0.6kW to 30kW and the temperature stability ranges from ±1℃ to ±0.1℃. For detailed chiller models, please go to https://www.teyuchiller.com
