Description

Technical Field

[0001] The utility model relates to the technical field of appearance detection, in particular to an appearance inspection device based on product processing. Background Art

[0002] In the visual inspection system, the device uses appropriate light sources and image sensors (such as the widely used CCD camera) to capture the surface image of the product. Then, through advanced image processing algorithms, the system can accurately extract the feature information in the image. Based on this key information, the system can accurately locate, identify and grade surface defects, thereby accurately determining whether the product's appearance is qualified.

[0003] In the existing product processing flow, a key step is to conduct an appearance inspection after the product is processed. However, the current inspection method can only determine whether the product appearance is qualified, but cannot automatically classify the products after inspection in detail. This means that staff will need to manually classify them later, which is not only time-consuming and labor-intensive, but also greatly reduces the overall production efficiency of the product.

[0004] Therefore, in view of the fact that the appearance inspection device for the above-mentioned product processing does not have the function of product classification, resulting in low product production efficiency, an appearance inspection device based on product processing can be designed. Through image detection and pneumatic structure, it is convenient to classify the product quality while inspecting the appearance of the product, thereby saving staff time. Utility Model Content

[0005] In order to overcome the problem that the appearance inspection device for product processing does not have the function of product classification, resulting in low product production efficiency.

[0006] The technical solution of the utility model is: a visual inspection device based on product processing, including a tripod, a workbench, a control console, a feeding conveyor belt, a good product conveyor belt, a defective product conveyor belt, a grabbing component, a detection component, and a lighting module; the tripod is fixed to the lower end of the workbench, the control console is installed at the front end of the workbench, the feeding conveyor belt is installed at the upper end of the workbench, the good product conveyor belt is installed at the upper end of the workbench and located at the left end of the feeding conveyor belt, the defective product conveyor belt is installed at the upper end of the workbench and located at the left end of the good product conveyor belt, the grabbing component with a pneumatic structure is installed at the upper end of the workbench and located at the right end of the good product conveyor belt, the detection component is installed at the upper end of the workbench and located at the right end of the grabbing component, and the lighting module with a built-in power supply is installed at the upper end of the workbench and located at the front and rear ends of the feeding conveyor belt.

[0007] Preferably, the tripod supports the entire workbench to ensure that the device is stable during operation. The loading conveyor belt can quickly convey the products to be inspected to the workbench, greatly improving the inspection efficiency. The good product conveyor belt and the defective product conveyor belt are respectively responsible for automatically classifying and conveying qualified and unqualified products, reducing manual intervention and improving accuracy. The grabbing component can quickly and accurately grab the product and place it on the good product conveyor belt or the defective product conveyor belt. The inspection component can accurately inspect the appearance of the product by transmitting the signal to the console, which controls the grabbing component to classify the product. The lighting module ensures uniform illumination of the product surface during inspection, thereby improving the accuracy of inspection.

[0008] Preferably, the grabbing assembly includes a gantry, a crossbeam, a guide rail, and an electric slider; the gantry is fixed to the upper end of the workbench, the crossbeam is fixed to the left end of the gantry, the guide rail is fixed inside the crossbeam, and the electric slider is slidably connected to the guide rail. The gantry serves as the supporting structure of the entire grabbing assembly, and the crossbeam is installed at the left end of the gantry, forming a transverse skeleton of the grabbing assembly, ensuring the stability of the entire assembly.
