Laser welding machine application on battery connector

The connector is a component that connects two active devices, transmits current or signals, and bridges communication between blocked or isolated circuits, thereby allowing current to flow and enabling the circuit to perform its intended function. Connector is an indispensable part of electronic device. You will always find one or more connectors when you look at the path through which the current flows. The form and structure of the connector are various. There are different types of connectors depending on the application object, frequency, power, and application environment.

With the development and demand for electronic products, today the high-power portable electronic products are integrated into our lives, power connectors are particularly important, to ensure battery life, it is necessary to use large-capacity batteries, and large-capacity batteries need high current battery connectors for energy transfer. The connector simplifies the assembly process of electronic products, it can be assembled by plugging and unplugging, which is easily operated. It also simplifies the mass production process, the standard industry specifications avoid the frustration at every turn finding a model with special specification.

Since the battery connector plays an important role in circuit connection and signal transmission in the system, once it fails, it will affect the normal operation of the connected device or even the entire system, and the internal solder joint of the battery connector is also one of the key factors which affect the reliability of the battery connector itself.
When the battery connector is soldered by traditional manual soldering, hot air welding or automatic iron soldering, the damage to the wire will be inevitable, and the "bridge" between the leads of the adjacent solder joints is easily formed.

The laser welding technology is used to weld the battery connector, the welding speed is fast, the depth is large, and the deformation is small. It can be welded at room temperature or under special conditions, and the Laser welding equipment is simple. Laser welding uses high-energy laser to locally heat the material in a small area. The energy of the laser spreads through heat conduction to the inside of the material, melting the material to form a specific molten pool.
The battery connector Laser welding machine of Shenzhen Sunlaser is mainly used for the welding of thin-walled materials and precision components. It can do spot welding, butt welding, stitch welding, sealing welding, etc. It has high depth-to-width ratio, small weld width, small heat affected zone, smooth and beautiful weld seam. No need further treatment or only simple processing is needed after welding, it has high weld quality, no porosity, precise control, small focus spot, high positioning accuracy, and easy automation.
