Description

TECHNICAL FIELD

[0002] At present, the quality of building materials directly affects the safety and durability of construction projects, and accurate and efficient detection of building materials is a key link to ensure project quality. With the continuous progress of automation technology, it is an urgent need in the industry to develop an automatic experimental device for building material detection to replace traditional manual detection methods and improve detection efficiency and accuracy.

[0003] Currently, the common building material detection equipment on the market mostly adopts a combination of manual assistance and simple machinery. For example, in the material positioning process, the building materials are usually placed on the conveyor belt by manual operation, and then the clamp position is manually adjusted for preliminary fixation. In the hardness and compressive strength detection process, a mechanical device with fixed pressure is generally used to apply pressure to the material, and the material performance is judged by manually reading the pressure data. For the size, shape and surface defect detection of the material, it mostly relies on manual visual observation and simple measuring tools.

[0004] However, in the traditional detection method, due to the individual differences and different operation proficiency of the operators, it is difficult to ensure the consistency and accuracy of the material placement position each time, which may easily lead to material positioning deviation. Once the material positioning is not accurate, the subsequent hardness and compressive strength detection and other processes will be affected, resulting in detection result error, which cannot truly reflect the actual performance of the building materials, and may bring potential risks to the quality control of the construction project.
