Full-automatic welding equipment for multi-thread airflow sensor

The invention discloses multi-thread airflow sensor full-automatic welding equipment which comprises a workbench. The sensor feeding set, the first welding set, the first reversing mechanism, the second welding set, the second reversing mechanism, the detection mechanism and the discharging mechanism are sequentially arranged on the workbench along the backflow conveying line, and a plurality of backflow carriers are arranged on the backflow conveying line; according to the automatic welding device, rapid feeding of a plurality of sensors is achieved through the sensor feeding set, simultaneous welding of a plurality of leads of the sensors is achieved through the first welding set and the second welding set, and reversing operation of the sensors between the first welding set and the second welding set is achieved through the first reversing mechanism; reset of the backflow carrier and reset of the sensor after welding are achieved through the second reversing mechanism, circulation cooperation of all the me
