Environment-friendly full-automatic positive solder ball global manufacturing machine

The utility model relates to the technical field of solder ball manufacturing, in particular to an environment-friendly full-automatic positive solder ball global manufacturing machine, and aims to solve the problems of air pollution and ozone layer destruction caused by potential influence of volatile organic compounds on the environment and human health in the positive solder ball manufacturing process. The automatic tin spraying device comprises a mounting frame, a conveying belt assembly, a driving device, a tin bath, a supporting frame, a tin melting furnace, a tin conveying pipe, a tin spraying head, a purifying device, a control device and a ball collecting box. The gas concentration in the air outlet pipeline of the purification device can be monitored in real time through a gas detector, and when it is detected that purified gas still contains pollutants with the high concentration, connection between the air outlet pipeline and the circulating pipeline is opened and closed through a first electromag
