Ultrasonic Electrode Welder
The Ultrasonic Electrode Welder uses pressure welding to apply appropriate pressure to the upper sonotrode to effectively transmit the generated sound waves to the welded joint surface, causing high-speed friction on the surface of the metal atoms, and the instantaneous high temperature generated by the high-speed friction of the joint Achieve welding effect, intelligent control mode, convenient operation, safe and reliable, strong power output and stable performance.
Ultrasonic welding of battery electrode ears is an efficient, reliable, and environmentally friendly battery manufacturing process. The battery electrode ear is a key component connecting the battery to external circuits, and its welding quality directly affects the performance and safety of the battery. Ultrasonic welding technology utilizes the energy generated by ultrasonic vibration to form a strong welding connection between the battery electrode ears and the battery body through instantaneous high pressure and frictional heat.
The process of Ultrasonic Electrode Welder usually includes the following steps:
Preparation stage: Firstly, it is necessary to ensure that the surface of the battery body and electrode ears is clean, free of oil and impurities, to ensure welding quality. Meanwhile, select appropriate ultrasonic welding equipment and corresponding welding parameters, such as welding time, amplitude, and pressure.
Positioning and alignment: Accurately place the electrode ears in the predetermined position of the battery body and perform alignment operations to ensure that the welding surface between the electrode ears and the battery body is tightly adhered without gaps.
Ultrasonic welding: Start the ultrasonic welding equipment and transfer ultrasonic energy to the contact surface between the electrode ear and the battery body through the ultrasonic vibration head. Under the action of ultrasound, the contact surface generates frictional heat and instantaneous high pressure, causing the material to quickly melt and form a welded connection.
Cooling and Curing: After welding is completed, the welding area needs to be cooled and cured to ensure the stability and reliability of the welding connection.
