Description

Technical Field

[0001] The utility model relates to the technical field of tooling system detection, in particular to an intelligent tooling detection device. Background Art

[0002] In the context of the ever-changing era of smart home appliance technology, home appliance products are developing towards high integration and intelligence at an unprecedented speed. This trend not only greatly enriches consumers' life experiences but also poses more stringent requirements for the home appliance repair industry. With the increasing complexity of the internal structure of home appliances and the new challenges brought about by the deep integration of software and hardware, the traditional repair method relying on manual experience judgment seems inadequate. Its low efficiency and limited accuracy often make it difficult to quickly locate the root cause of problems when facing complex and changing faults, resulting in an extended repair cycle and a decline in customer satisfaction. In particular, with the formation of the global market, home appliance products circulate across national borders, and the cross-regional repair demand has increased sharply. Due to the disadvantages of traditional on-site repair models, such as geographical restrictions, high travel costs, and lagging response times, it has become difficult to meet the requirements of rapid response, cost control, and efficient resource allocation. This not only increases the operating costs of enterprises but also limits the coverage of repair services, affecting user experience and brand reputation.

[0003] Upon further examination of the existing technology, it is not difficult to find many of its limitations. Firstly, the limitations of detection means lead to insufficient detection accuracy and depth, making it difficult to timely capture many faults hidden at deep or microscopic levels, which poses a potential hazard to subsequent repair work. Secondly, the low level of intelligence makes the repair tools lack the ability of self-learning and optimization, and each repair needs to start from scratch, with low efficiency and difficulty in adapting to constantly changing fault types. Moreover, the lack of remote support technology restricts the flexibility and scalability of repair services, making it difficult to timely meet the cross-regional repair demand.
