At present, most enterprises still adopt a primary pure manual processing and a semi-automatic mode of an auxiliary jig due to the influence of the problems of wire demand and the like. Manual processing typically includes: the wire is manually loaded into the carrier, then the length required to be cut is measured, and then fixed-length cutting is performed. The method is a set of fast and efficient working procedures, if the working procedures are finished by manual work alone, a great deal of manpower is required to finish the series of actions, the production efficiency is seriously affected, and the subjective influence of the production process is larger and the quality consistency is poorer. The auxiliary jig carrying out scheme generally includes: the wire is manually placed into the wire cavity of the jig, then the upper and lower cutters fixed on the jig are combined to cut the wire, and the auxiliary jig is used for cutting the wire, so that the procedure is more standard than that of pure manual operation, and the operation procedure is less than that of the pure manual operation, but the operation time is longer than that of the pure manual operation; because it needs the cooperation of people and tool to use, this auxiliary jig's cutting method also needs a large amount of manual work and tool to maintain the going on of production, and production efficiency and cost are all considerable.
