A device for automatically producing screw connections, having an articulated arm robot and a screwing unit which can be rotated about an effector axis by an output element of an end element of the articulated arm robot. The screwing unit has a housing, wherein a screwing tool is movably received in the housing along the effector axis between a feed position and at least one screwing position, and wherein a mouthpiece for providing a screw is arranged on the housing.

The present invention provides a screw feeding device including a nozzle assembly, a quick-release assembly, and a screw feeder body. The quick-release assembly is mounted on the nozzle assembly to allow it to be removably attached to the screw feeder body. The assembly includes a seat body, a pushing member, and an elastic member. The pushing member is movably placed in a sliding slot of the seat body and has a limiting groove with a tapered width. The elastic member is positioned in the limiting groove and has two linkage portions extending wider in the opposite direction. Each linkage portion is provided with a fixing pin, which are elastically positioned within a groove of a housing of the screw feeder body. When the pushing member moves relative to the elastic member, the elastic member deforms, causing the fixing pins to move closer and detach from the screw feeder body.

A fastening tool includes: a bit holding portion which detachably holds a driver bit and is configured to rotate in a circumferential direction of the driver bit and move in an axial direction of the driver bit; a motor configured to perform at least one of rotation of the bit holding portion and movement of the bit holding portion along the axial direction; a contact member which contacts a fastening target and is configured to move in the axial direction; a control unit configured to control a timing at which driving of the motor is stopped based on a movement amount of the contact member in the axial direction when the contact member contacts the fastening target; a contact arm which is movable in the axial direction in conjunction with the contact member; and a position detection unit configured to detect a position of the contact arm.

A clutchless autofeed screwdriving tool designed to prevent overdriving screws into a workpiece. A user positions the tool onto a workpiece and presses down on a nosepiece, which then retracts a slide body inside the tool. The tool includes a sensor that, when contacted by a rear portion of the slide body, sends a first signal to a controller to stop a motor. Once the motor stops, a drive bit also stops rotating, thereby preventing overdriving a screw into a workpiece. The user then removes the tool from the workpiece, and the slide body automatically extends. When the slide body moves out of contact with the sensor, the sensor sends a second signal to the controller to start the motor, which then starts the drive bit rotating again.

A supply device for joining elements. The supply device includes a receiving portion for at least one joining element, in which a joining element is receivable and positionable in front of a first opening, a circumferentially closed hose of a flexible material which on a first end is connected with the receiving portion and on an opposite, second end with a discharge portion, as well as a flexible thrust element which is movable back and forth using a drive means through the hose between a retracted position in which a front end of the thrust element is located in the receiving portion and an extended position in which the front end is located in the discharge portion, so that the joining element which is positioned in front of the first opening is pushable with the thrust element out of the receiving portion through the hose into the discharge portion.

A device that positions a series of fasteners in front of a driver, includes a positioner and a coupler. The positioner is operable to locate a fastener in front of the driver, and includes a receiver, a rocker, and a roller. The receiver holds and guides a clip that holds a plurality of fasteners adjacent each other. The rocker moves the clip through the receiver such that each of the plurality of fasteners is sequentially positioned in front of a bit of the driver, ready to be driven into a material. The coupler is operable to couple the positioner with the driver, and includes a mount and a body. The mount is operable to releasably fasten the coupler with the driver. The body holds the positioner while the positioner moves relative to the body, and has a groove in which the roller travels as the positioner moves relative to the body.

An autofeed screwdriver attachment that includes a spool and a spool support. The spool support configured to be fastened to a handle of an autofeed screwdriver. The spool support includes a first panel mounted to a first side of the handle, a second panel mounted to a second side of the handle, and a spool hanger positioned between the first and second panel. The spool includes an elongate shaft and a retainer. The elongate shaft extending vertically from a first end to a second end. The retainer is fastened proximate to the first end of the elongate shaft, and the elongate shaft is removably fitted to the spool hanger proximate to the second end. The spool is configured to retain a screw cartridge above the retainer.
