Description

Technical Field

[0001] The utility model relates to the field of intelligent assembly line systems, and more specifically, to an assembly line monitoring device. Background Art

[0002] The assembly line is a cargo handling machine that continuously transports goods on a certain route, also known as a conveyor line or conveyor. According to the conveying series products, it can be roughly divided into seven types of assembly lines: belt assembly line, plate chain line, multiple chain line, plug-in line, mesh belt line, suspension line and roller assembly line. The assembly line has a large conveying capacity and a long transportation distance. It can also be modified in various ways. During the conveying process, several other process operations are completed at the same time, so it is widely used in industrial production. However, general assembly lines are for transportation and have no detection function. However, the intelligent control of electronic equipment currently still needs to be operated by the user, and the user selects the control target and method. It cannot automatically respond quickly according to the conditions of the production workshop. For example, if there is too much smoke in the workshop, it is easy to cause fire, toxic gas leakage, dust concentration exceeds the safety value, etc., it is crucial to discover and make judgments one second earlier.

[0003] At present, automated assembly line production has become a modern production method. By writing and setting up relevant computer programs and using computer programs to control mechanical equipment for automated production, automated assembly line production has changed the traditional manual production mode, so that the production process no longer requires direct human participation, which can greatly improve production efficiency and ensure production safety, and avoid many work-related injuries. At present, automated assembly line production has been widely used in various industries such as industrial production, agricultural production and service industry in my country. Automated assembly line production meets the requirements of modern standardized production, and the products produced can ensure uniform specifications. In addition, automated assembly line production also effectively saves part of human and material resources and can reduce production costs. Therefore, automated assembly line production has brought great benefits to people.
