Automatic screw twisting machine for photo frame

Abstract

The invention relates to the field of automatic screw twisting machines and in particular relates to an automatic screw twisting machine for a photo frame. The automatic screw twisting machine comprises a worktable and a screw locking device, wherein a photo frame fixing jig composed of a positioning rod and two groups of pneumatic clamps is arranged above the worktable; the screw locking device comprises an automatic screw arraying unit and a screw locking unit; the automatic screw arraying unit is provided with a vibration disc sorting mechanism and a screw storage guide rail, so that automatic feeding of screws is realized; the screw locking unit is used for controlling a bit assembly on the screw locking unit to move to an appointed position through a lifting air cylinder and a transverse positioning screw rod; then a screwdriver bit is driven by a driving motor to lock screws, which are conveyed by the automatic screw arraying unit through a screw conveying pipe, to edge corners of the photo frame; the equipment is simple and easy to operate, and the screws in an assembling process of the photo frame can be automatically twisted, so that manpower is saved, errors are reduced and the assembling efficiency can be remarkably improved.
