the tin soldering position is positioned by adopting a camera vision, other mechanisms are accurately controlled to reach the designated position by an industrial control computer, and each terminal of the product can further adopt a method of positioning and tin soldering so as to ensure the accuracy of the tin soldering position of each terminal soldering cup of the product;

because some terminal welding cups of the connector face towards two sides, the positioning rotating mechanism is provided with a rotating shaft to achieve the function of automatically rotating the connector, and each row of terminal welding cups of the connector are tinned after being adjusted to a proper position;

the product positioning jig of the positioning and rotating mechanism can be designed according to the shape of an actual product, the jig can be replaced when different products are processed, a product positioning block and a pressing device can be further adopted, a universal product placing groove is formed in the product positioning block, the product is pressed and positioned on the product positioning block by the pressing device, and therefore the product positioning jig is suitable for processing and manufacturing various products, the jig does not need to be replaced, and the material changing time is shortened.

The soldering tin equipment for the table type soldering iron has the advantages that the structure is simple, the soldering tin position is accurate, no solder residue exists on the outer surface of the soldering cup of the product terminal, no gold layer is plated on the outer surface of the soldering cup, other positions of the product cannot be damaged, the processing quality of the product can be ensured, manual operation is replaced by the equipment, and the yield and the production efficiency of the product can be improved; the table type soldering iron tin soldering equipment can be further matched with a robot or a manipulator to realize full-automatic operation; the soldering tin of the table type soldering iron tin soldering equipment can be used for soldering a connector product and other electronic products, such as circuit boards of PCBs and the like, and can be further optimized and improved in adaptability on the structure of the positioning rotating mechanism according to specific products.
