[0002] The gas sensor array preparation device is a machine for automatic, intelligent and continuous preparation of freshness gas sensor arrays. The gas sensor arrays involved are widely used in the freshness monitoring of meat, fruits and vegetables.

[0003] In recent years, as the public pays more and more attention to the freshness of food, especially the food industry, the demand for freshness gas sensitive sensor arrays has increased significantly.

[0004] Traditional methods such as capillary spotting, pipette spotting or inkjet printing are used to deposit gas-sensitive reagents on a substrate to prepare a freshness gas-sensitive sensor array. Although the operation is simple, these spraying devices have single functions, low intelligence, and relatively low spraying efficiency. During the preparation process, the automated preparation of the freshness gas-sensitive sensor array is very limited. Summary of the invention
