Embodiment Construction

[0020] Combine below Figure 1-3 The present invention will be specifically described.

[0021] Add a MES system (Manufacturing Execution System) engine number error prevention scanning point before engine assembly, scan the vehicle VIN (Vehicle Identification Number) of the engine to be assembled and the barcode number on the engine before assembly, and then the MES system will automatically The vehicle VIN is uniquely bound to the engine's own barcode number;

[0022] When the engine is assembled, scan the VIN of the whole vehicle and the barcode number of the engine to be pasted on the vehicle file. If it is consistent with the binding result, paste it on the vehicle file. At this time, the vehicle VIN and the engine number on the vehicle file will be established One-to-one correspondence between barcodes; if it is inconsistent with the binding result, it will be resolved according to the abnormal problem handling process, see figure 2 .

[0023] When the whole vehicle ...

Abstract

The invention discloses an engine number mistake proofing method based on an MES (manufacturing execution system). The method is characterized in that: the mistake proofing is realized by establishing and checking the unique corresponding relationship between the VIN (vehicle identification number) of the entire vehicle and the barcode number of the engine in the vehicle assembly process. The method disclosed by the invention comprises the following steps of: establishing an MES mistake proofing platform; establishing one-to-one corresponding relationship between the engine number and the VINof the entire vehicle in the MES by scanning; then, scanning in the process to realize accurate assembly of the real engine and accurate sticking of the engine barcode for files on the vehicle; checking the matching accuracy among the engine number of files on the vehicle, the real engine number and the VIN of the entire vehicle by scanning again before final inspection; and finally realizing theaccuracy of the collected data for printing a certificate of approval.

Description

technical field [0001] The invention belongs to the field of automobile assembly manufacturing, and in particular relates to an engine number error prevention method based on an MES system. Background technique [0002] The engraved number of the vehicle engine is the only certificate of the engine and the consistency of the VIN of the vehicle plays an important role in car anti-theft. The printing of the qualification certificate of the assembly line production vehicle is mainly in the last process in terms of production process arrangement. The principle of number selection Mainly the engine number barcode copied from the accompanying documents. The principle of taking the number of the on-board document is mainly to paste two barcodes that are consistent with the engraved number of the engine together with the engine before the engine is assembled on the whole vehicle, one of which is pasted on the engine, and the other is pasted on the on-board document. If this process...
