Description

Technical Field

[0001] The utility model relates to the technical field of screw assembly, in particular to an automatic screw tightening device. Background Art

[0002] At present, many parts of devices need to be locked and fixed by screws. Traditional screw tightening operations are manually operated, but manual operations are inefficient and prone to errors. Therefore, automatic screw tightening devices have appeared on the market. The automatic screw tightening devices are mainly used to complete the screw picking, placing and tightening operations through automated mechanisms instead of manual operations. When in use, the device to be assembled is placed on the positioning mechanism and sent to the screw tightening station. The screw tightening gun is moved down and locked, and multiple screw holes on the same surface can be assembled. However, the screw tightening gun generally only moves in the horizontal and vertical directions and cannot be screwed in screw holes on different surfaces. Therefore, the positioning mechanism also has a rotation function, which can change the direction of the device to be assembled and send the other side to be assembled under the screw tightening gun for screw tightening. However, some devices to be assembled are not convenient to change direction, and internal parts may be misplaced or fall off. The screwing of such devices requires multiple screw tightening guns in different directions to complete, which greatly increases the processing cost. Utility Model Content
