Description

Technical Field

[0002] The development and research of batteries has become an area of ​​concern for many people. Batteries are widely used in consumer electronics and electric vehicles due to their high energy density, long service life, green and pollution-free, and high safety performance. At the same time, people's demand for batteries is becoming more and more intense. How to achieve high safety and high energy density of batteries has become the current research focus. With the continuous development of the battery industry, the current collector has a better performance composite current collector, that is, a composite current collector composed of modified polymers and metals. Because the middle layer of the composite current collector is a modified polymer, there are two main welding processes in the application of batteries: laser welding and ultrasonic welding. For traditional copper foil and aluminum foil, both processes can be used to weld the foil and the composite current collector together. During the welding process, the metal foil and the metal layer on the side of the composite current collector are fused at high temperature, and welding is achieved after cooling. Then the foil is welded to the pole ear, thereby improving the flow capacity of the composite current collector. With the continuous development of science and technology, people have higher and higher requirements for the manufacturing process of the composite current collector transfer welding integrated device.

[0003] However, the traditional composite current collector welding device has certain drawbacks when in use. The conveying process of the material strip is unstable and prone to shaking, and even the foil area of ​​the material strip may be folded or warped, affecting the welding quality.
