Description

automatic feeder

technical field

The invention relates to a feeder in the motor assembly process, in particular to an automatic feeder capable of simultaneously supplying shaft cores and casings.

Background technique

The structure of the small motor includes a shell and a shaft core. During production, the shell and the shaft core are molded separately, and then fed to the injection molding machine for assembly. One side of the shell has a gap, and the gap needs to face a specified direction during the assembly process. direction, so the loading of the shell needs to meet the requirements of this direction. In the prior art, the outer casing and the shaft core are supplied by the vibrating plate, and only one shaft core and one outer casing can be supplied at a time, so the manipulator matched with the injection molding machine can only take one shaft core and one outer casing to the injection molding machine at a time. On the machine, while on the injection molding machine, multiple groups of shaft cores and shells are assembled at the same time. The assembly work can only start, and this process takes a lot of time, resulting in low assembly efficiency. In addition, the openings of the shells delivered by the vibrating plate are randomly oriented, and after loading the materials into the injection molding machine, it is necessary to adjust the direction manually or by other mechanisms, which further reduces the assembly efficiency.
