[0001] The present invention relates to the field of round rod transportation, and more particularly to a round rod feeding device. Background Art

[0002] When producing plastic products, some plastic products require round rods to be placed into the mold as inserts for injection molding. To improve efficiency, manufacturers often use robots to place the round rods into the mold.

The round rods need to be loaded onto a jig to facilitate the robot to grab them.

[0003] The existing method of loading round rods into the jig is for workers to place the round rods into the jig. This is not only inefficient and has high labor costs, but also prone to accidents due to fatigue of workers after working for a long time.
