Abstract

The invention relates to a method for providing production-related data in the series production of produced objects, especially motor vehicles, according to which production-related data is recorded in at least a part of the production steps of the series production process. The inventive method is characterised in that images of defective sites on the produced objects are recorded with a camera and in that during the production process, the recorded images are transmitted to at least one central device. The inventive method provides a rapid, simple and comfortable means of documenting defects in produced objects. The recorded images and production-related data that may be optionally added to these images are already available at the central device and can be evaluated at a time when the produced object is still in the production process. This facilitates the planning of refinishing considerably, which in turn saves time and reduces costs.

Claims

1. A method for making available production-related data in a series production process for the production of produced objects, especially motor vehicles,

in accordance with which, during at least a portion of the finishing sections of the series production process, a worker captures production-related data via a hand-held data acquisition device having an information input component,

characterized in that,

pictures of defect locations on the produced objects are captured by means of a camera associated with the data acquisition device and

the pictures are transmitted during the performance of finishing work on the produced objects in the series production process to at least one central device.

2. A method according to claim 1, characterized in that, a digital camera is used to capture pictures of defect locations.

3. A method according to claim 1, characterized in that, the pictures are transmitted in the form of digital picture data to the central device.

4. A method according to claim 1, characterized in that, the pictures are taken by workers.

5. A method according to claim 1, characterized in that, the data acquisition device comprises a screen display device for the display of captured pictures.

6. A method according to claim 5, characterized in that, the screen display device is configured as a touch screen via which the production-related data gathered by a worker is inputted into the data acquisition device.

7. A method according to claim 1, characterized in that, the captured pictures are, as required, subjected to follow-on work before transmission thereof to at least one central device, especially for more exact identification and/or classification of defect locations.

8. A method according to claim 1, characterized in that, the data acquisition device is associated with a respective worker.

9. A method according to claim 1, characterized in that, at the beginning of a first predetermined finishing section of the series production process, a data acquisition device is associated with each produced object and that the data acquisition device stays with the respective produced object until a second predetermined finishing section is reached.

10. A method according to claim 1, characterized in that, preferably from the beginning of the capture of pictures of defect locations, a code is inputted or read into the data acquisition device associated with the respective produced object of which pictures of defect locations are to be captured so as to thereby identify the produced object, whereby, together with the captured pictures or separate therefrom, data is transmitted to at least one central device which contains the code for identification of the respective produced object which has had pictures thereof captured by the camera and transmitted to at least one central device.

11. A method according to claim 10, characterized in that, the code is transmitted in a wired manner to the data acquisition device, in particular via a transponder.

12. A method according to claim 10, characterized in that, the code for identifying the produced object is a graphical code, in particular, a line code (bar code) and the graphical code is captured via the camera.

13. A method according to claim 12, characterized in that, the graphical code is, together with the captured pictures, transmitted to the at least one central device or is transmitted separate from the pictures and, following its transmission, is de-coded to identify the produced object.

14. A method according to claim 12, characterized in that, the graphical code is de-coded before the transmittal thereof to the at least one central device.

15. A method according to claim 12, characterized in that, the graphical code is stored in memory and is de-coded by means of a picture processing program.

16. A method according to claim 1, characterized in that, the input device comprises an audio input device for the recording of audio information, whereby the audio information, together with the captured pictures or separate therefrom, is transmitted as additional data to the at least one central device.

17. A method according to claim 3, characterized in that, the digital picture data and, as the occasion arises, the further data relating to the picture data are transmitted in a wired manner or in a wireless manner, in particular, in a wireless manner via radio, to the at least one central device.

18. A method for making available production-related data in a series production process for the production of produced objects, especially motor vehicles, the method comprising:

during at least a portion of the passage of the produced objects through a plurality of finishing sections of the series production process, capturing by photographing means production-related data concerning non-conforming locations on the produced objects, the photographing means being associated with a data acquisition device in a manner such that captured production-related data can be inputted to the hand-held data acquisition device; and

transmitting the captured production-related data from the data acquisition device to at least one central device during a time period during which finish work still remains to be performed on the produced object during its passage through the plurality of finishing sections of the series production process.

19. A method according to claim 18, wherein the photographing means is a digital camera operable to capture pictures of non-conforming locations.

20. A method according to claim 18, wherein the production-related data comprises pictures transmitted in the form of digital picture data to the central device.

21. A method according to claim 18, wherein the production-related data comprises pictures taken by workers.

22. A method according to claim 18, wherein the data acquisition device comprises a screen display device for the display of captured pictures.

24. A method according to claim 18, wherein the production-related data comprises captured pictures which are, as required, subjected to follow-on work before transmission thereof to at least one central device, especially for more exact identification and/or classification of defect locations.

25. A method according to claim 18, wherein the data acquisition device is associated with a respective worker.

26. A method according to claim 18, wherein at the beginning of a first predetermined finishing section of the series production process, a data acquisition device is associated with each produced object and that the data acquisition device stays with the respective produced object until a second predetermined finishing section is reached.

27. A method according to claim 18, wherein the production-related data comprises pictures and, preferably from the beginning of the capture of pictures of non-conforming locations, a code is entered into the data acquisition device associated with the respective produced object of which pictures of non-conforming locations are to be captured so as to thereby identify the respective produced object, whereby, by means of a selected one of a bundled transmission with the captured pictures or non-bundled transmission separate from the captured pictures, data is transmitted to at least one central device which contains the code for identification of the respective produced object which has had pictures thereof captured by the camera for subsequent transmittal to at least one central device.
