[0002] With the development of society and economic progress, cars have entered thousands of households. The tailgate is an important part of the car. During the design process of the tailgate, it is necessary to ensure that it has sufficient structural performance during the opening and closing process. Due to its frequent use and the phenomenon of violent closing, if the structural performance of the tailgate is insufficient when it is open, it will cause a large deformation of the tailgate when it is closed, or even permanent deformation and interference with surrounding parts, which will cause parts damage, parts not fitting, etc., thus affecting the normal use of the tailgate. The performance test of the tailgate is carried out after the prototype car is produced through experimental testing or the designer's own experience.

[0003] Existing inspection tooling utilizes fixed inspection sensors, such as GT2, which utilizes cylinder mechanical contact for inspection. First of all, it is a special machine, and product changes require redesigning and developing new equipment and purchasing new sensors, which is costly, and adding points is troublesome, and there is a risk of scratching the painted surface of the product when it comes into contact with the product. Fixed inspection sensors can only detect plastic tailgate products with relatively fixed sizes, and cannot detect plastic tailgate products with size differences. Therefore, the utility model proposes a plastic tailgate size flexible laser detection device to solve the above problems. Utility Model Content
