Description

Backlight detection jig Technical Field The utility model belongs to the technical field of detection jigs, and particularly relates to a backlight detection jig. Background As shown in fig. 7, the mobile phone spindle-like hardware product 1 is in a long and thin strip shape. In the production and manufacturing process of the product 1, accurate detection of the outer length and the outer width of the product is a key link for ensuring the quality of the product. At present, the traditional detection mode mostly depends on manual measurement or adopts a secondary element detection device. The manual measurement is low in efficiency, the requirement of mass production in the modern mobile phone manufacturing industry is difficult to meet, the manual measurement is greatly influenced by human factors, and the accuracy and consistency of the measurement result are difficult to ensure. The existing two-dimensional detection equipment, such as a two-dimensional measuring instrument, is mainly used for two-dimensional plane detection of thinner products (such as shrapnel) and smaller products or two-dimensional projection detection of other workpieces, and is generally used for placing a product to be detected on a detection jig during operation, photographing the product to be detected through an optical image measuring device such as a camera of the two-dimensional measuring instrument, and obtaining the accurate size of the product to be detected after image recognition and calculation. The related prior art is Chinese patent utility model with the application number 201922490853.9 and the patent name of a high-precision two-dimensional measuring instrument. Although the secondary element detection device improves the detection accuracy to some extent, there is a disadvantage in the detection efficiency. If the product 1 is placed on the detection jig, the product is not easy to position due to the long strip shape, so that the overall detection efficiency is limited. In addition, for the product 1 with extremely high requirement on dimensional accuracy, when a single photographing is adopted to measure a longer dimension, the camera of the secondary measuring instrument needs to photograph at a longer distance from the product 1, so that the overall measurement accuracy is reduced, and the quality control requirement of high accuracy cannot be met. Therefore, there is a need for a detecting tool for detecting the external length and the external width of a mobile phone rotating shaft type hardware product, which can improve the detecting efficiency and ensure the measuring precision, and is suitable for mass production. Disclosure of utility model In order to solve the technical problems in the prior art, the application provides the backlight detection jig which can detect the outer length and width of a strip-shaped product in a batch and high in detection efficiency.
