[0002] Inkjet code detection refers to the process of detecting and verifying the inkjet code information on the product. The inkjet code detection machine is a device specially used to detect the inkjet code information on the product. It usually uses high-precision technologies such as optical character recognition (OCR) and image processing technology to automatically identify and verify the inkjet code information on the product to ensure its accuracy.

[0003] The existing inkjet coding inspection with defective detection is to send the product to be inspected onto the conveyor belt or workbench of the inkjet coding inspection machine, and use the fill light device on the visual camera to fill light on the product. At the same time, the visual camera will automatically scan and collect the inkjet coding image data for inspection. Since different products have different materials and colors, and the external light source shines on the product, the contrast between the product packaging color and the product inkjet coding is not high, which will affect the visual camera scanning of the product inkjet coding information, thereby affecting the inkjet coding inspection effect.

[0004] Therefore, it is necessary to design a coding inspection machine that can block external light sources for different products, prevent external light sources from affecting the detection of product coding, and improve the accuracy of product coding detection and has defective detection capabilities. Utility Model Content

The lifting frames are slidably connected to the shading hood, the adjusting screw is rotatably connected to the front middle part of the shading hood, and the lifting frame is threadedly connected to the adjusting screw.

[0009] Preferably, the telescopic curtain is made of high-density polyester cloth.

[0010] Preferably, a turning handle is provided on the adjusting screw.

An upper and lower support block are connected to the right front part of the light shield, a motor is connected between the support blocks, and the motor output shaft passes through the light shield and is connected to the sponge tube. The sponge tube is rotatably connected to the light shield.

[0012] The beneficial effects of the utility model are as follows: 1. The utility model adjusts the rotation of the screw to make the lifting frame move up and down, and then makes the telescopic screen move up and down, so that the product to be inspected is located within the telescopic screen and the light shield, thereby achieving the effect of being able to shield external light sources for different products, avoiding the influence of external light sources on the detection of product inkjet coding, and improving the accuracy of product inkjet coding detection.
