Embodiment Construction

[0150] figure 1 Process flow equipment, generally indicated at 100, is shown.

[0151] The process plant 100 is in particular a painting plant 102 .

[0152] The process flow facility 100 preferably includes a plurality of processing stations 104 .

[0153] In this case, the process plant 100 , in particular the painting plant 102 , includes seven treatment stations 104 .

[0154] Preferably, a production process can be carried out on a workpiece 106 , in particular a vehicle body 108 and / or a vehicle accessory, by means of the process plant 100 .

[0155] In particular, one or more process steps of the production process can each be carried out in a plurality of processing stations 104 .

[0156] figure 1 The illustrated process plant 100 , in particular the painting plant 102 , is here in particular a painting line 110 .

[0157] In the coating line 110, the processing stations 104 are preferably connected in series with each other.

[0158] For example, it is conceiva...

Abstract

The invention relates to a method for the analysis of quality defects in workpieces, preferably in vehicle bodies and/or in attachment body parts, particularly after and/or when undergoing a production process in process plants, preferably after and/or when undergoing a painting process in painting plants, by means of which quality defects can be prevented and/or by means of which the causes of quality defects in the production process can be determined, prevented and/or rectified. According to the invention, the method comprises the following: - establishing a workpiece-specific data set uniquely assigned to a workpiece at the start of a production process, particularly at the start of a painting process and/or establishing a workpiece carrier-specific data set uniquely assigned to a workpiece carrier at the start of a production process, particularly at the start of a painting process; - supplementing the workpiece-specific data set while a workpiece is undergoing the production process, particularly the painting process, with process data particularly relevant to quality and/or supplementing the workpiece carrier-specific data set while a workpiece carrier is undergoing the production process, particularly the painting process, with process data particularly relevant to quality; - storing the workpiece-specific data set in a database and/or storing the workpiece carrier-specific data set in a database.

Description

technical field [0001] The invention relates to a vehicle body, preferably for analyzing workpieces, in particular after and / or while passing through a production process in a process plant, preferably after and / or while passing through a painting process in a painting plant and / or quality defects of vehicle accessories. Background technique [0002] When purchasing a motor vehicle, buyers who acquire such a motor vehicle expect high-quality motor vehicle paintwork. The respective purchaser wishes here, for example, that the vehicle body and / or the vehicle accessories are free from paint defects, ie free from dirt impurities, dents, sags, scratches and / or air impurities (bubbles), for example. Buyers also expect the color distribution, tone, gloss and / or sheen of the vehicle body to remain the same. It is also desirable that the structure of the various coatings and / or lacquer layers be at least approximately uniform and / or that the layer thicknesses of the coatings and / or...
