This operation mode can clean the liquid preparation unit 2 alone. If the liquid preparation unit 2 and the spray unit 3 need to be cleaned at the same time, the valve on the recovery pipe 132 is closed. The recovery pipe 132 keeps the third quantitative delivery pipe open, and the cleaning water can pass through the solvent bottle 21, the liquid preparation bottle 22, the storage bottle 23 in sequence and enter the spray bottle 31 to complete the cleaning operation. The operation method is relatively flexible and can be selected according to actual needs; two doors 14 are hinged on the outer box body 1, one of the doors 14 is used to open and close the liquid preparation chamber 11, and the other door 14 is used to open and close the spray chamber 12. The arrangement of the doors 14 facilitates the adjustment and coordination of the components inside the outer box body 1, and an observation window is provided on the door 14 for easy observation.

[0064] The implementation principle of the present invention is: the first quantitative conveying mechanism 211 first conveys different solvent bottles 21 to the liquid preparation bottle 22 separately in proportion, and then the proportioned solvent in the liquid preparation bottle 22 is input into the storage bottle 23 through the second quantitative conveying mechanism 221. The storage bottle 23 is connected to the spray unit 3 through the third quantitative conveying mechanism 231, so that the spray unit 3 can realize the spray operation on the thin layer plate 51. During the spray operation, the lifting mechanism 7 first drives the nozzle 331 to move to a suitable height position, and the first horizontal moving mechanism 6 drives the nozzle 331 to move horizontally for spraying. The second horizontal moving mechanism 10 can also adjust the position of the placement seat 5 and the thin layer plate 51 according to the spraying requirements. After the spraying is completed, the cleaning unit can be switched according to actual needs to clean the spray unit 3 and the liquid preparation unit 2.
