Definitions

  • the invention relates to a method according to the preamble of claim 1 and a device according to the preamble of claim 9 for introducing a preservative into cavities of assemblies or components such as a motor vehicle body.
  • a device for preserving cavities of a vehicle body is in DE 10 2005 036 342 described.
  • This device comprises a nozzle frame with spray nozzles arranged thereon, which are each assigned to a cavity to be preserved, and a positioning device for aligning the nozzle frame relative to the body.
  • the device has a magazine with a plurality of different nozzle frames and at least one industrial robot with whose arm a nozzle frame can be connected by a coupling.
  • This arrangement offers through the possible replacement of the nozzle frame increased flexibility in mass production, however, the device is dependent on input of different body types on an external input to adjust the corresponding system parameters (such as the amount of preservatives) and perform a tool change.
  • the invention has for its object to develop a method and an apparatus of the type described above, which make it possible to perform the preservation, without relying on an input of the component type from the outside.
  • the inventive method or device is characterized in that a detection of a workpiece to be machined by a non-contact multi-dimensional measurement, and pass the result of this measurement to a control device as a basis for the control of a positioning and the control of an applicator and the preservation process becomes.
  • Detection of the assembly to be machined is accomplished by non-contact multidimensional measurement, and the result of this measurement is provided to the controller as the basis for control of the positioning and control of the applicator and preservation process.
  • the method and the device according to the invention by means of automatic component recognition offers a higher process reliability, since operating errors can be reduced or avoided by, for example, erroneous inputs as a result of this measure.
  • the sensors are advantageously designed as optolelektronische sensors. Very well suitable for this purpose are lasers whose reliability has already been proven many times in practice (claim 11).
  • the device may be surrounded by an at least partially closed on all sides cabin with ventilation device, the access to the cabin interior, for example, for the purpose of workpiece change is made possible by a gate.
  • the workplace safety is increased and in combination with the ventilation device, the impairment of operating or monitoring personnel is also minimized by released preservative and noise.
  • the door is advantageously provided with means to prevent opening during the preservation process, consisting of a safety device connected to the control device and an associated sensor which signals the state of the door (claims 3 or 14).
  • the component receptacle of the positioning device is designed as a linear guide and provided with a centering device in order to achieve a stable and precise positioning in the working space.
  • This centering device may consist of a cone which engages in an opening provided on the workpiece for the purpose of centering. (Claims 4 or 15).
  • the applicator has a nozzle bar which can be precisely and stably aligned with respect to the positioning device via at least two axis guides (claims 5 or 16).
  • the drive of the linear guides is advantageously carried out electrically, so a fast and precise movement is possible (claim 17).
  • the nozzle bar may be provided with one nozzle per cavity to be sealed, this allows a short processing time per module (claim 18).
  • the drive of the spray nozzles is advantageously carried out electrically, thereby a fast and precise movement is possible (claims 7 or 20).
  • the individual spray nozzles are controlled in each case advantageously by a separate valve for preservative dosing, thereby ensuring an exact volume control. (Claims 8 or 21).
  • the equipped with rolling or sectional door (2) and ventilation device (3) cabin (4) completely encloses the working space.
  • the workpiece (5) to be preserved is placed in the component receiving device (6) with centering device (which lingers in a transfer position) and then fixed by a clamping device (not shown). Thereafter, the roll or sectional door (2) is closed and locked.
  • a safety device, not shown detects the closing and prevents opening of the door (2) during the preservation process.
  • the component receptacle (6) is movable via an electrically driven linear guide (7) in at least two axes and ensures that the workpiece (5) is now moved stable and precise from the transfer position to the working position.
  • the workpiece (5) is classified:
  • the independent module detection by means of non-contact multidimensional measurement advantageously takes place via three laser sensors (8) arranged mutually orthogonally independently of one another. These sensors supply their signals to the control device (9), which is advantageously designed as an industrial PC and controls all associated sensors, Akttoren and facilities.
  • the ventilation device (3) is now put into operation to supply the working space with fresh air.
  • the spring-loaded nozzle beam (10), initially in a rest position, is movable in two directions via an electrically operated linear guide (11) and is thus aligned precisely with respect to the workpiece (5).
  • On the nozzle bar (10) are in turn the spray nozzles (12) with bracket. These can also be moved via linear guides in two directions to be adapted to the workpiece to be preserved (5). Thus, a higher flexibility of the device is achieved.
  • the nozzle bar (10) is moved to the application position, i. the spray nozzles (12) are introduced into the respectively assigned cavities in the workpiece (5).
  • the spray nozzles (12) are supplied with preservative via a piping (13) and high-pressure hoses (14), wherein each individual spray nozzle is controlled via a separate solenoid valve (15).
  • the dosage of the preservative is volumetric.
  • the nozzle bar (10) moves back to the rest position, the component holder (6) transports the workpiece (5) into the transfer position.
  • the ventilation device (3) is deactivated.
  • the rolling or sectional door (2) can now be unlocked and opened, the workpiece (5) is ready after removal of the clamping device for removal.
