Description

Technical Field

[0001] This utility model belongs to the technical field of height detection devices, and in particular relates to a height error-proof detection device suitable for production lines. Background Technology

[0002] For process engineers, every operation involves mistake-proofing. Mistake-proofing measures prevent product defects or non-conforming products caused by human error or operational mistakes, ensuring the stability and consistency of product quality. It also reduces waste of raw materials, rework, and scrap caused by incorrect operations, thereby lowering production costs.

[0003] Mistake-proofing measures simplify and standardize operations, reduce production interruptions and delays caused by errors, and improve the smoothness and efficiency of the production process. They also help identify potential problems and weaknesses in the process, providing a basis for process improvement. Based on the effectiveness of mistake-proofing measures, companies can continuously optimize process design and operating procedures, thereby improving overall process efficiency.

[0004] By observing the error-proofing measures on the production line, we found that our company frequently conducts random checks on the height of semi-finished rotors, using digital height gauges in the inspection room. This results in inspectors moving back and forth between the inspection room and the production line during the random height checks. On the one hand, this increases the workload of the inspection team; on the other hand, when inspection personnel change models for random checks, operators have to wait, reducing their actual working hours. Furthermore, digital height gauges are relatively expensive, and we require a large number of height detection devices. Therefore, we need to design a height error-proofing detection device suitable for the production line to improve production efficiency and ensure product quality. Utility Model Content
