The wire number identification system includes a wire stand, a bobbin, an actuator and a control terminal; the wire stand includes a box body and a wire stand platform located above the box body, and a plurality of bobbin grooves are evenly distributed on the thread stand platform, and the bottom of the bobbin groove has A through hole, a bobbin rod is inserted in the through hole of each bobbin groove, the rod diameter of the bobbin rod matches the aperture of the through hole of the bobbin groove, the bobbin rod can move up and down along the through hole of the bobbin groove; The protruding structure can be stuck at the through hole of the spool slot; each spool rod is interspersed with at least one spool, and the spools inserted on the same spool rod have the same thread, and the spools inserted on different spool rods have different wire numbers . Number the spool rod, record the position information of the spool rod at the same time, record the position of the spool rod where the threads of different thread colors are stored, control the terminal to search for the thread, and push the spool rod out through the actuator, and remove the spool for operation. This structure can greatly improve the convenience of taking the bobbin and improve the processing efficiency.
