Description

Technical Field

[0001] The utility model relates to the technical field of instant noodle production, in particular to a noodle cake visual detection device. Background Art

[0002] As a fast-cooking food, instant noodles are deeply loved by the public. The main material is noodles, which are stacked in layers to form a round or square cake structure. However, in the process of making instant noodles, defects such as oil stains, burnt noodles, undercooked noodles, and damaged noodles will appear on the surface of the noodles. As people's living standards improve, they pay more and more attention to food hygiene. Consumers often find foreign matter in instant noodles, which will affect the brand image and product sales and reduce the production efficiency of enterprises. Therefore, foreign matter detection in instant noodles is an important detection issue in the production process.

[0003] At present, most factories use manual on-site inspection to inspect and select noodles. However, manual inspection is not accurate, and manual inspection is labor-intensive and inefficient. In addition, personnel are prone to carry various foreign objects to cause secondary pollution. Manual inspection is also prone to missed inspections, which affects the quality of noodles. Therefore, a noodle visual inspection device is needed to solve the above problems. Utility Model Content

Therefore, when inspecting the dough cakes, the dough cakes are conveyed to the conveyor belt by the conveyor belt mechanism, and the driving rollers are driven by the driving mechanism, so that the dough cakes are conveyed by the conveyor belt. At this time, the top line scanning camera and the bottom line scanning camera are used to visually inspect the dough cakes. At the same time, the top light source and the bottom light source are used to illuminate the dough cakes. The top line scanning camera and the bottom line scanning camera are illuminated by the top light source and the bottom light source. After scanning and taking pictures, the software system analyzes and processes the images to determine whether the dough cakes are qualified. Unqualified products are manually rejected after taking pictures, and qualified products are conveyed to the dough cake packaging area of ​​the next process, thereby achieving the effect of double-sided inspection of the dough cakes and accurate detection of foreign matter attached to the dough cakes.
