[0024] The conveying mechanism 2 comprises a conveying mechanism 2.

[0025] The positioning mechanism 3 comprises a first positioning mechanism 31 and a second positioning mechanism 32, the first positioning mechanism 31 comprises a positioning table 311, a first positioning cylinder 312 arranged on the positioning table 311 and a first positioning claw 313 fixedly arranged at the end of the piston rod of the first positioning cylinder 312, and the second positioning mechanism 32 comprises a second positioning cylinder 321 arranged on the rack 11 and a second positioning claw 322 fixedly arranged at the end of the piston rod of the second positioning cylinder 321.

[0026] As Figs. 1-3As shown, in actual use, the contact lens solution is stored in the storage tank 13 and transported to the filling assembly 12 through the infusion tube 14. The transport mechanism 2 moves the contact lens solution container to the filling station. The first and second positioning claws of the positioning mechanism 3 limit the container from different directions to ensure its stability during the filling process. The filling assembly 12 fills the contact lens solution according to the preset program. The valve 143 controls the filling volume to ensure the accuracy and consistency of each filling. After filling is completed, the transport mechanism 2 removes the filled container or contact lens for subsequent packaging or testing. The entire device ensures the efficiency and quality of contact lens solution filling through precise positioning and stable transportation.
