Lithium battery adapter welding machine

Lithium battery adapter welding machine

I. Working principle

Laser welding principle: A high-energy-density laser beam is focused on the connection between the adapter and the battery electrode, so that the material melts and fuses together instantly. Laser welding has the advantages of concentrated energy, fast welding speed, narrow and deep welds, and small heat-affected zone. It can achieve high-precision welding and ensure good electrical and mechanical connection between the adapter and the electrode.

II. Structural composition:

Welding head: It is a key component for realizing welding operations. According to different welding technologies, such as laser welding head or ultrasonic welding head, it is responsible for generating and outputting corresponding welding energy to the welding part.

Workbench: It is used to place the lithium battery to be welded and fix the adapter. It usually has a precise positioning device to ensure that the adapter can be accurately aligned with the battery electrode to ensure the welding quality.

Control system: It is like the "brain" of the equipment. It can set welding parameters such as welding power, welding time, pressure (for ultrasonic welding), etc.

III. Features

High welding quality: Good weld quality can effectively avoid welding defects such as false welding and leaking welding, and ensure the electrical performance and safety of lithium batteries in subsequent use.

High precision: With the help of precise positioning devices and advanced welding technology, the adapter can be accurately welded to the specified position, and the error can usually be controlled within a very small range, which is crucial for the compactness of the internal structure of the lithium battery and the stability of its performance.

High efficiency: Compared with traditional manual welding methods, lithium battery adapter welding machines can complete a large number of welding tasks in a short time. Equipment with a high degree of automation can achieve continuous and uninterrupted welding operations, greatly improving the production efficiency of lithium batteries.

Wide range of applications: It can adapt to the welding needs of lithium batteries of different models and sizes and adapters of various materials, and has strong versatility.

IV. Application fields

New energy vehicle field: With the rapid development of new energy vehicles, their power battery packs are usually composed of a large number of lithium battery cells connected in series, parallel, etc.

Energy storage field: In lithium battery energy storage devices used in energy storage power stations, home energy storage systems, etc., adapter welding machines are also needed to ensure effective connection between batteries, so as to achieve efficient storage and release of electrical energy.
