摘要:
In an automatic screw tightening apparatus, a feed head unit is movable to and from close contact with a driver bit portion. The driver bit portion contacts the screw and sucks the head portion of the screw in close contact. The feed head unit includes a longitudinal groove opened to the outside and connected to a vertically extending screw feed hole. Only a thread portion of the screw is capable of horizontally advancing and retreating in the longitudinal groove.
