Problems solved by technology

[0003] At present, there are no experimental methods and experimental equipment for body-in-white air-tightness test in the market and in the actual automobile manufacturing industry, so the air-tightness test of body-in-white cannot be carried out. The problems caused by this mainly include: the sealing effect of body-in-white cannot be evaluated; It is impossible to evaluate the sealing effect of overlapping areas such as glue coating, welding seams, and partition blocks; it is impossible to confirm the leakage area of ​​the body-in-white; it is impossible to record the leakage amount, so further comparative analysis and technical improvement cannot be carried out

Abstract

The invention discloses a body-in-white air-tightness detection system and a detection method. The system comprises at least eight organic glass plates, a pressure sensor, a fog generator, a blower fan and an air input sensor, wherein the organic glass plates are in sealing connection with each glass window on the body-in-white to form a sealed body chamber, the fog generator and the blower fan are respectively in sealing communication with the body chamber, the pressure sensor is arranged in the body chamber, and the air input sensor is arranged between the blower fan and the body chamber. The system has a simple structure, realizes low cost and guarantees that the experiment result is accurate, air-tightness detection and leakage positioning can be effectively realized through repeated body-in-white air-tightness detection in short time, and body-in-white air-tightness can be guaranteed.

Description

technical field [0001] The invention relates to a detection system, in particular to a body-in-white airtightness detection system. [0002] The present invention also relates to a method for detecting the airtightness of the body-in-white by using the above-mentioned airtightness detection system. Background technique [0003] At present, there are no experimental methods and experimental equipment for body-in-white air-tightness test in the market and in the actual automobile manufacturing industry, so the air-tightness test of body-in-white cannot be carried out. The problems caused by this mainly include: the sealing effect of body-in-white cannot be evaluated; It is impossible to evaluate the sealing effect of overlapping areas such as glue coating, welding seams, and partition blocks; it is impossible to confirm the leakage area of ​​the body-in-white; it is impossible to record the leakage amount, so further comparative analysis and technical improvement cannot be car...
