The invention discloses a three-needle parallel winding and blocked stator winding machine. The three-needle parallel winding and blocked stator winding machine comprises an equipment bottom rack, a three-dimensional winding mechanism, a blocked stator placement jig, a tensioner main body, a safety protection cover, a trimming device, a clamping device, a turnover workbench, a winding device and ahuman-computer interface, wherein the three-dimensional winding mechanism is arranged at an upper end of the equipment bottom rack, the winding device is arranged in front of the three-dimensional winding mechanism, the turnover workbench is arranged at a position, arranged at a front surface of the three-dimensional winding mechanism, of an upper end of the equipment bottom rack, the trimming device and the blocked stator placement jig are arranged on the turnover workbench, the trimming device is arranged at a lower end of the blocked stator placement jig, the safety protection cover is arranged at an upper end of the equipment bottom rack, and the tensioner main body is arranged at an upper end of the safety protection cover. By matching, the function that a line passing through blocked motor stators is not broken is achieved, subsequent wire end trimming and wire end welding are greatly reduced, and the production efficiency is improved.
