Lithium battery welding machines are commonly used for spot welding connections of lithium batteries, where welding caps is an important step in the welding process to protect the weld points and ensure welding quality. The following are several common welding cap methods:
1. Manual coverage: The operator manually covers the welding cap on the welding point before welding, ensuring that the welding point is completely covered. This method is suitable for situations where welding quality requirements are not high and production speed is not very fast.
2. Automatic covering: Using automated equipment such as automatic welding robots or welding machine accessories, welding caps can be automatically covered on the welding points. This method can improve welding efficiency and consistency, and reduce the labor intensity of operators.

3. Self adhesive welding cap: Use a self-adhesive welding cap, which is attached to the welding point before welding. After welding is completed, the welding cap will automatically adhere to the welding point. This method is simple and easy to implement, suitable for situations with fast welding speed and high production efficiency requirements.
4. Magnetic welding cap: Magnetic welding caps have magnetism and can be magnetically attached to solder joints. This method is easy to operate, but it requires ensuring that the magnetic force of the welding cap is strong enough to prevent it from falling off during the welding process.
5. Vacuum adsorption welding cap: Using a vacuum adsorption device, the welding cap is vacuum adsorbed onto the welding point to ensure tight contact between the welding cap and the welding point.
This method is suitable for situations where high welding quality is required and can ensure stable welding quality.
The method of selecting welding caps should be determined based on specific production needs, the characteristics of welding equipment, and the requirements for welding quality. Each method has its applicable scenarios, and choosing the appropriate method based on the actual situation can improve welding efficiency and quality.
