Cylindrical lithium battery automatic spot welding machine is an advanced manufacturing equipment that integrates mechanical, electrical, control, sensing, and computer technology. It mainly focuses on spot welding the positive and negative electrodes of cylindrical lithium batteries to ensure the stability of the internal structure and reliable electrical performance of the battery.
2、 Working principle
The working principle of the automatic spot welding machine for cylindrical lithium batteries is to apply pressure to the positive and negative electrodes of the cylindrical lithium battery through electrodes, and use the resistance heat generated by the current passing through the contact surface and adjacent areas of the joint for welding. During work, two electrodes squeeze the workpiece, causing a certain contact resistance between the two layers of metal under the pressure of the two electrodes. When the welding current flows from one electrode to another, instantaneous thermal welding is formed at two contact resistance points, completing the welding process.
3、 Equipment features
Efficiency: By adopting advanced automation control systems, high-speed and continuous spot welding operations can be achieved, greatly improving production efficiency. For example, the production efficiency of some models of automatic spot welding machines can reach 3600-4500PCS/H.
Accuracy: High precision mechanical structure and precise sensor technology can ensure precise alignment between electrodes and battery plates, avoiding welding deviations and virtual welding phenomena. At the same time, through advanced control algorithms, key parameters such as current, voltage, and temperature during the welding process are monitored in real time to ensure that each welding reaches the optimal state.
Intelligence: The device has intelligent characteristics and can be connected to the upper computer or intelligent manufacturing system to achieve functions such as remote monitoring, fault diagnosis, and data statistical analysis. This further improves the convenience and intelligence level of production management.
Customizable: Based on the actual needs of customers, the equipment can be personalized to meet the special requirements of specific application scenarios. For example, customized spot welding molds and automatic polishing of welding needles can be used.
