The system includes a set of air-delivery and receiving cabinets that are connected to each sampling field device through a conveying channel, and the air-delivery and receiving cabinets are arranged in a circular arc. , the first manipulator is placed in the center of the arc, and the grinding and tableting integrated machine is placed on the side of the first manipulator away from the air-feeding and receiving cabinet group. The second manipulator and the packaging device on the side of the second manipulator are arranged on the side of the integrated grinding and tableting machine away from the first indexing manipulator, and the second manipulator is far away from the grinding press. A testing instrument is installed on one side of the integrated chip machine.

Although the technical solution realizes the automatic completion of the whole process from sample preparation to obtaining the test results, the efficiency is significantly improved compared with the previous ones, and the accuracy of the test results is guaranteed. However, the practice shows that this technical solution has the following obvious defects: 1) Relying on robots to complete the transfer between each unit of equipment not only covers a large area, but also is not convenient for maintenance and debugging of equipment; 2) It can only be suitable for a single variety of samples , weak adaptability.
