The invention discloses a full-automatic template sewing machine, which comprises a plurality of sewing machine heads, a machine frame, a table plate, a template, an automatic template clamping device mounted on the table plate and provided with a template, and an X- and Y-direction drive mechanism for driving the automatic template clamping device to move on the table plate, wherein the machine frame is H-shaped and comprises two frame legs, a cross beam arranged between the frame legs, and a main shaft fixedly mounted on the frame legs, positioned on one side of the cross beam and parallel to the cross beam; the table plate is mounted between the frame legs of the machine frame and positioned under the cross beam; and the sewing machine heads are mounted on the main shaft and can move along the main shaft. According to the full-automatic template sewing machine, the complicated process is simplified and standardized based on the characteristics of the clothing template, so that the efficiency is improved, the production time is shortened, the reject ratio is reduced, and the degree of dependence on highly skilled personnel is reduced. The full-automatic template sewing machine is higher in stability and can be used for sewing a plurality of the same patterns at the same time or cooperatively making complicated patterns.
