[0002] The following problems usually exist in the production of automotive lamps: In traditional automotive lamp production, size adjustment usually requires a lot of manual intervention, including manual adjustment and visual inspection. At the same time, in order to reduce the difficulty of production and improve product qualification rate and quality, there is a relatively common special design in through-type lamps or other larger products, such as setting an adjustable eccentric positioning pin. When the product appearance size deviates, the position of the positioning pin can be adjusted to improve product quality and achieve the center of the loading position. In the past, manual inspection tools were used to measure and find deviations, and then the eccentric screws were manually adjusted and measured again until it was centered. This manual reliance on manual methods can easily lead to low production efficiency and the possibility of human error. Moreover, the traditional manual adjustment method may not be able to achieve sufficient accuracy, especially for the strict requirements of automotive lamp size. Factors such as uncertainty in manual operation and wear of mechanical parts will affect the accuracy of adjustment.

[0003] In view of this, it is necessary to design a new automatic inspection fixture with a size self-adjustment function that can overcome the above technical difficulties and effectively solve or alleviate the above technical difficulties. Summary of the invention
