Application and advantages of automatic welding machine in the production of surge protection device

The soldering process uses the melting of metal tin to fill the connection gap between two metal objects to ensure that the two metal objects are connected as a whole and maintain the connection firmness and conductivity between the two metal objects.

   The stability of the soldering process is closely related to the relevant process parameters in the soldering process, and mainly includes the following key factors:

1. The material properties of the welding surface of the metal parts;

2. The cleanliness of the welding surface;

3. The amount of solder (solder amount);

4. Soldering temperature;

5. Welding time;

    The material properties of the welding surface of metal parts and the cleanliness of the welding surface can be effectively controlled by the product structure design.

In conventional manual soldering, the three factors of solder material quantity (solder amount), soldering temperature, and soldering time can only be realized by the operation skills of the soldering operator. To determine the quality of soldering by operating experience, only fuzzy qualitative control can be performed. The welding quality is affected by the technical level of the operator and the fluctuation of mood factors, and there are certain fluctuations.

Product defects caused by welding defects account for a considerable proportion in the statistics of the causes of product quality problems. Therefore, the automatic welding process can be used to determine the amount of solder (solder volume), welding temperature, and welding time in the welding process. Three Factors are improved from artificial fuzzy qualitative control to intelligent quantitative control, and it is a very necessary measure to ensure the consistency and stability of welding quality of welded parts.

    Since 2018, Thor Electric has invested funds to transform the welding production process, changing the welding of the conductive parts in the production of surge protection device from manual welding to automatic welding machine welding, increasing the solder pass rate of surge protector products by nearly 99.9% , to provide a good production process foundation for the production of surge protector products with stable quality.
