  • Patent number: 6278077
    Abstract: A welding method and system for welding a workpiece at weld locations includes a weld controller having control logic and stored data related to weld locations and workpiece dimensions. The weld controller is operable with a displacement sensor for monitoring the displacement between the electrodes of a weld gun. The control logic is programmed to generate a move signal based upon the stored data and the displacement between the electrodes. The weld controller also has stored data related to primary and alternate weld locations. The control logic is programmed to generate a fault signal based upon the stored data and a welding parameter such as the displacement between the electrodes. The weld controller provides a fault signal to the position controller to index the weld gun from a primary weld location to an alternate weld location when a comparison of the welding parameter to stored data related to the primary weld location indicates that the workpiece has been improperly welded.

  • Patent number: 6020569
    Abstract: A welding system for real-time weld quality detection during resistance welding of a workpiece has a sensor assembly including a winding and a core mounted generally coaxially within the cylinder of the welding gun. A piston and piston rod assembly are mounted for coaxial movement within the cylinder. The piston rod has an end protruding from the cylinder for affixing an electrode thereto. Axial movement of the piston rod relative to the cylinder causes axial movement of the core relative to the winding to vary a length of core and winding overlap. The sensor assembly produces an output signal based on the length of core and winding overlap to indicate piston rod position relative to the cylinder. Weld control logic receiving the sensor assembly output controls welding of the workpiece in real-time.

  • Patent number: 5818008
    Abstract: An apparatus and method for resistance welding tubular parts is disclosed. The apparatus includes a weld gun having displaceable electrodes with contact faces engaging the parts. The contact faces are designed to distribute the forces applied to the parts by the electrodes to prevent deformation and to hold the parts together steadily in order to minimize undesired electrode displacement. A test computer monitors the amount of electrode displacement occurring as a result of penetration of the parts into each other during welding. When the displacement between the electrodes falls within a predetermined displacement range, which is indicative of a proper weld between the parts, the computer cooperates with a weld controller to terminate the welding power, thereby inhibiting any substantial further penetration of the parts. The apparatus and method is suitable for tube-to-tube and wire-to-tube applications commonly performed in the manufacture of automobile seats.

  • Patent number: 5808266
    Abstract: A system and method is disclosed for monitoring and controlling a resistance projection welder for welding a projection weld nut to a workpiece. A displacement sensor measures the displacement of a welding electrode of a weld gun in real time during the welding procedure. A computer is coupled to the displacement sensor and determines whether the projection weld nut is correctly loaded between the workpiece and the welding electrode. The computer instructs a programmable logic controller (PLC) to trigger a weld controller to apply power to the welding electrode if the projection weld nut is correctly loaded onto the workpiece. The computer instructs the PLC to inhibit power if it determines the projection weld nut to be inverted, missing, or misaligned in order to allow for the removal and replacement of the projection weld nut.

  • Patent number: 5808265
    Abstract: Control systems and methods for inspecting at least one of a plurality of parts using an inspection station are disclosed. A comparator coupled to the inspection station compares a test signal responsive to a measured parameter of a part in the inspection station to a reference signal to determine if the part matches a predetermined profile. The comparator then provides a fault signal which disables the inspection station upon determining that a part matches the predetermined profile. The profile matching part is then removed from the inspection station and stored in a storage device. The storage device then provides a confirmation signal to the comparator indicating that the profile matching part has been stored in the storage device. The comparator then enables the inspection station upon receipt of the confirmation signal.

  • Patent number: 5645738
    Abstract: An apparatus and method for resistance welding tubular parts. The apparatus includes a weld gun having electrodes with arcuate contact faces engaging the parts. The electrodes are displaceable relative to each other. The contact faces are designed to distribute the force applied to the parts to prevent deformation and to hold the parts together steadily in order to minimize the amount of undesired electrode displacement caused by these effects. A test computer monitors the amount of electrode displacement occurring as a result of penetration of the parts into each other during welding. When the displacement between the electrodes falls within a predetermined displacement range, which is indicative of a proper weld between the parts, the computer cooperates with a weld controller to terminate the welding power, thereby inhibiting any substantial further penetration of the parts.

  • Patent number: 5614109
    Abstract: A control system and method for inspection of parts is particularly adapted for inspecting resistance welded parts in a production line environment. A displacement sensor is coupled to a welding electrode for generating a displacement sensor signal responsive to the displacement of the welding electrode during welding. A test computer evaluates the displacement sensor signal to identify defective parts and to provide a fault signal. A part containment box receives the improperly welded parts and has an input sensor for generating a signal when an improperly welded part is deposited therein. The test computer is operative to disable the production line and prevent the indexing of parts until the defective part has been removed from the production line and deposited into the part containment box which generates the input sensor signal, thereby enabling the production line.
