Description

Technical Field

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

[0002] Screw assembly refers to the process of using screws to connect two or more components together. This process can be carried out manually or with the use of screwdrivers, wrenches, and other specialized tools. With the rapid development of technology, in the production of existing equipment, many use automation for screw assembly operations. Automatic screw assembly greatly improves the assembly efficiency of screws and can also avoid the situation where screws are not installed in place during manual screw installation. However, in the existing technology, most of the automatic equipment for screws can only perform screw assembly operations on workpieces with specific size specifications. When performing screw assembly on different workpieces, it is necessary to disassemble and replace the corresponding workpiece carrier to continue using.

The workpiece slot 63 is rotated and adjusted to make the workpiece slot 63 fit the workpiece, and then the output end of the electric telescopic rod three 65 is extended and inserted into the positioning pin hole 7 to position the conversion frame 62. At this time, a group of workpiece slots 63 above the conversion frame 62 receive a group of workpieces to be assembled, and then the electric telescopic rod two 52 drives the mounting table 54 to slide and adjust in the guide groove, and then the infrared detection sensor 66 is used to position the screw clamped by the screw clamp 36, and then the electric telescopic rod one 33 drives the screw downward to correspond to the screw hole of the workpiece, and then the rotating cylinder 35 operates to rotate and assemble the screw, thereby completing the assembly operation of the screw;

[0024] When the workpiece slot 63 is used to receive the workpiece, it is necessary to rotate the cylinder 55 to drive the bearing clamp 53 to rotate so that the bearing clamp 53 is out of the buckled state with the mounting platform 54, and then the electric telescopic rod 2 drives the mounting platform 54 to slide along the guide groove so that the position of the workpiece slot 63 corresponds to the discharge end of the loader 2. When the workpiece slot 63 is docked and the workpiece is taken, the electric telescopic rod 2 drives the mounting platform 54 to return to its initial state, and then the rotating cylinder 55 drives the mounting platform 54 and the bearing clamp 53 to continue to be in the buckled state.
