Problems solved by technology

Since the tip of the probe has a certain thickness, it cannot detect the depth of the details of the character gully, and it needs to be pressed manually during use, so there are certain subjective factors in the measurement results
Traditional detection methods have problems such as high labor costs, low efficiency, poor quantification accuracy, subjectivity, and easy omissions
With the increase of car ownership and sales, the workload of motor vehicle manufacturers and vehicle annual inspection agencies to detect VIN codes and engine numbers has also increased rapidly. The traditional mechanical detection method can no longer meet the needs of the market.

Abstract

The invention discloses a portable device for detecting the depth of an engraved character. The device comprises a mechanical casing body, a clamping mechanism, rollers, a display screen and a laser triangulation optical path unit. The laser triangulation optical path unit includes a linear laser, a reflecting mirror, a lens and an image sensor; a filter piece is arranged between the image sensorand the lens; and a glass window is arranged at the bottom of the mechanical casing body. In addition, the invention also discloses a method for detecting depth of an engraved character. A trigger signal is generated; 3D contour data of a character surface are sampled and character characteristic data represented by a character scanning contour line are calculated; and then a character detection result is finally displayed. Therefore, non-contact comprehensive detection of the depth or height of the coded character, the size of the character, and the distance between adjacent characters can berealized; the manual detection cost during the process of motor vehicle manufacturing and annual inspection can be lowered; the detection accuracy and detection efficiency can be improved; and the technical problems existing in the industry can be solved.

Description

technical field [0001] The invention relates to the technical field of vehicle manufacturing, in particular to a portable depth detection device and detection method for engraved characters. Background technique [0002] The traditional motor vehicle VIN code and engine number detection mainly relies on manual visual inspection. Some car companies use a dial gauge with a probe to detect the depth of the VIN code and engine number. Since the tip of the probe has a certain thickness, it cannot detect the depth of the character gully details by itself, and it needs to be pressed manually during use, so there are certain subjective factors in the measurement results. Traditional detection methods have problems such as high labor costs, low efficiency, poor quantification accuracy, subjectivity, and easy omissions. With the increase of car ownership and sales, the workload of motor vehicle manufacturers and vehicle annual inspection agencies to detect VIN codes and engine number...
