Problems solved by technology

In this production mode, in the collinear production and assembly, the model identification is carried out by VIN code identification. Once there is a mismatch between the VIN code and the model, there will be serious confusion and errors in the subsequent production part configuration, which will lead to the scrapping of the vehicle.

Embodiment Construction

[0012] The specific implementation of the present invention, such as the shape and structure of each component involved, the mutual position and connection relationship between each part, the function and working principle of each part, etc., will be further described in detail through the description of the implementation examples below.

[0013] The comparison and anti-error method for marking the VIN code of the body-in-white of the present invention comprises the following steps:

[0014] A. Install sensors near the suspension on the engine compartment fixture of the body-in-white to detect the difference of the suspension;

[0015] B. Send the differential signal of the sensor to the marking device, and compare it with the VIN code information instantly scanned by the scanning gun of the marking device;

[0016] C. If the difference signal matches the VIN code information, the marking device will perform normal marking, otherwise an error will be reported.

Abstract

The invention provides a comparison error proofing method for body-in-white VIN (vehicle identification number) code marking. The comparison error proofing method includes arranging sensors on a body-in-white engine compartment fixture close to suspension parts; transmitting a difference signal of each sensor to marking equipment and comparing the difference signal to VIN code information instantly scanned by a scanning gun of the marking equipment; and enabling the marking equipment to perform normal marking if the difference signals are matched with the VIN code information, and executing an error reporting step if the difference signals are not matched with the VIN code information. The sensors are used for detecting differences of the suspension parts for different vehicle models. The comparison error proofing method has the advantages that the differences of the engine suspension parts are additionally detected, the difference signals are compared to the VIN code information instantly scanned by the scanning gun of the marking equipment, and accordingly the VIN code information is prevented from being mismatched with the vehicle models during production.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to a comparison and error prevention method for marking a VIN code on a body-in-white. Background technique [0002] At present, the body-in-white welding production line mostly adopts the "multi-model collinear production mode". In this production mode, in the collinear production and assembly, the model identification is carried out by VIN code identification. Once there is a mismatch between the VIN code and the model, there will be serious confusion and errors in the subsequent production part configuration, resulting in the scrapping of the vehicle. Contents of the invention [0003] The purpose of the invention is to propose a comparison and anti-error method for marking the VIN code of the body-in-white. [0004] According to the comparison and anti-error method of marking the VIN code of the body-in-white provided by the present invention, the method com...
