Definitions

  • the present disclosure relates to a joining device, in particular a joining device adapted to join a workpiece arrangement (for instance at least two sheet or workpieces arranged one above the other) with a joining element and without pre-formed (for example pre-drilled or pre-punched) hole or holes in the component prior to the joining comprising a clamping device.
  • the present invention also relates to a process for joining a workpiece arrangement.
  • Joining methods and joining devices of the above-mentioned kind are widely known, especially in the field of punch riveting or direct screwing ... and are used for example in automotive engineering.
  • the clamping device ensures different functions such as pressing together the members of a workpiece arrangement to avoid any gap between the workpieces, avoiding or influencing a possible displacement of adhesive between the workpieces, reducing the workpiece deformation during the joining process.
  • Document DE 10 2005 031 917 A1 discloses a method for joining in which, in a first step, a main piston and a clamping device are pressed against the workpieces with a comparatively low force, so that the workpieces are held immovably in contact with one another and with a die.
  • Document CH689299 discloses a joining device comprising a clamping device with a probe for checking the position of a rivet or a workpiece.
  • Document DE102017106449 discloses a joining device with a hydraulic system and comprising a punch with which a linear, nonrotating setting movement can be executed, a clamping device with which one or more components can be compressed in a joining direction, and with a drive unit that operates in at least two steps with which the punch and the clamping device can be moved by one motor and several gearboxes.
  • DE102012019809A1 discloses a method for punch riveting two sheets arranged one above the other on a base of a punch riveting device, between which an adhesive is introduced.
  • the joining device to perform the method comprises a C-frame with a die, a punch and a clamping device.
  • An electric motor is arranged to drive the punch and the clamping device.
  • the clamping force profile of the clamping device is either estimated considering the spring characteristics or is a constant with hydraulic and pneumatic systems.
  • the entire force applied to the workpiece arrangement by the joining device is formed by the addition of the clamping force and the force generated by the punch.
  • the entire force acts on the robot supporting the joining device and/or the workpiece arrangement, which leads to a need to provide a robust equipment which is cumbersome, expensive and requires large space.
  • double-sided joining like for instance the self-piercing riveting
  • the entire force leads to the bending of the C-frames used. Such bending causes lateral and angular offsets and has an impact on the joint quality. Larger robots or equipment to avoid these drawbacks are costly, requires space and provide a lower agility.
  • An object of the present invention is therefore to provide a joining device which is flexible, compact and a joining method by means of which the joining process can be better controlled and hence performed more effectively.
  • the present invention provides a joining device according to claim 1 and a joining method according to claim 13. More particularly, the joining device for joining workpieces comprises a joining head having:
  • the addition of a second drive unit to control the clamping device allows the clamping device to be controlled independently or depending on the punch.
  • the clamping device can be controlled and/or monitored on force and/ordisplacement, and in addition with possible with time-delay.
  • the clamping device can apply, during the setting steps of the joining element with the punch different clamping forces to or displacement with regard to the workpieces.
  • the clamping device can be eventually rigidly attached to the second drive unit (without stiffness-reducing measures such as springs or dampers), and thus a precise displacement or force can be applied, without corrective measures.
  • the addition of another drive unit in a joining device is always regarded as a problem, since it increases the weight of the device and complicates the control command.
  • the second drive unit is a servo-electric drive with a spindle.
  • the servo-electric drive is lightweight, and easy to control. No need of hydraulic or pneumatic connection.
  • the first drive unit is a servo-electric drive with a spindle.
  • the first and/or second drive unit could also be a hydraulic and/or pneumatic and/or electric drive unit.
  • a linear or a rotational drive unit may also be considered
  • the second drive unit moves the clamping device along a clamping axis, the clamping axis being parallel to but not confluent with the joining axis.
  • the clamping axis extends parallel to the joining axis at a non-zero distance. This improves the flexibility for the motion of the clamping device with regard to the retaining device of the punch. The clamping force is still applied at the or in the vicinity of the joining point.
  • the second drive unit is oriented at an angle with regard to the first drive unit, the angle being between 0 and 90 degrees.
  • the compacity or space requirement of the joining device can thus be improved.
  • a thermal device is arranged on the clamping device and moves together with the clamping device.
  • the thermal device can be a plasma torch, or a laser heating system, and induction heating system, an electric arc or similar.
  • the joining device may be used to perform a thermally assisted joining process such as a plasma joining or a joining process with plasma cleaning.
  • the clamping device comprises a surface detection unit adapted to detect a surface of the workpiece.
  • the clamping device thus performs several functions.
  • the surface detection can be done with or without contact. For instance, a laser distance measurement can be realized, an inductive or capacitive sensor can also be used. A mechanical contact measurement can equally be implemented.
  • the surface detection of the workpiece may help to determine the best joining parameters (displacements, ...) during the setting step or eventually detect possible mistakes (absence of a workpiece).
  • the joining device is adapted to measure a temperature.
  • the clamping device comprises a hollow cylindrical clamp adapted to be arranged around the punch and the retaining device.
  • the clamping device does not interfere with the punch or the retaining device but acts on the workpiece area to be joined directly.
  • the clamping device comprises a clamp having a C-shaped cross-section or a U-shaped cross-section.
  • the clamping device or clamp is in two parts with a first part having a C or U-shape in cross-section and a second part being cylindrical and hollow. The first part being adapted to face the workpiece arrangement. The second part being adapted to be connected to the rest of the joining device.
  • the clamp has an external diameter between 10 and 30 millimeters. This allows a precise clamping area portion without interfering with the punch or the retaining device.
  • the clamping device may, in cross-section, have a C-shape, have a U-shape, have a ring-shape with apertures or slots arranged at different angles, or be parallelepipedal or be composed of two or more parallelepipeds.
  • clamping pins or rods may be used.
  • one, two, three or more clamping pins may be used.
  • the shape of the clamp may be variable along its length. For instance, the three or more pins may be connected to a ring.
  • the joining device comprises a load measurement system.
  • the load measurement system is a load cell.
  • the load measurement system may be integrated within the joining device or more particularly the clamping device (internal system) or may be external.

  • the punch may also comprises its own load measurement system.
  • the present invention is also directed to a joining method for joining at least two workpieces with a joining device comprising the following steps of:
  • the clamping device can apply a high first pre-determined clamping force to the workpiece, to close any gap which might be present between the workpiece or, during a thermally assisted joining process to optimize the heat transfer between the first and the second workpiece. Due to the design of two axis (clamping axis and joining axis), the clamping force may thus be decreased, and may even thus be cancelled ) by the setting force on a need basis and replaced by the setting force. Depending on the process parameters, materials to be joined and joining element, the setting of the clamping force and setting force may be freely implemented.
  • the clamping device comprises a sensor unit providing force, displacement and time data.
  • clamping force profile and clamping device displacement profile and/or clamping force profile and joining element displacement profile and/or clamping force and time profile are recorded.
