Detailed implementation manners

[0022] The present application will be described in detail below in conjunction with embodiments, but the present application is not limited to these embodiments.

[0023] The present application provides a liquid injection device for contact lens processing, including:

[0024] A base 1 for providing support, and an operation panel 2 is further provided on the base 1, and the operation panel 2 is used to place a target workpiece to be injected with liquid;

[0025] A rotating shaft 3 is installed on the base 1 and is used to rotate the liquid injection assembly;

[0026] The liquid injection assembly includes a liquid storage tank 4, a plurality of liquid injection devices 5 and a plurality of connectors 6. The liquid storage tank 4 is connected to one end of the rotating shaft 3 away from the base 1, and a plurality of the liquid injection devices 5 are connected to the side surface of one end of the liquid storage tank 4 away from the rotating shaft 3 through the corresponding connectors 6, and the liquid injection device 5 is used to inject liquid into the target workpiece;

[0028] A cleaning tank 7 for cleaning the liquid injection device 5;

[0029] A drying box 8 for drying the liquid injection device 5 after cleaning;

[0030] The drying box 8 is a hollow box body with a through hole 17 at the top, and the diameter of the through hole 17 is adapted to the maximum diameter of the liquid injection assembly, so that the liquid injection device 5 to be dried can extend into the interior of the drying box 8 for drying operation.

[0031] It should be noted that the second motor drives the liquid injection assembly to rotate in the same direction, and the rotation angle each time is 90°. After a liquid injection device 5 staying on the operation panel 2 completes the liquid injection operation, when it needs to be cleaned, the second motor is started to drive the liquid injection device to rotate. A cleaning tank 7 and a drying tank 8 are arranged on the loop where the liquid injection device rotates. In this embodiment, a liquid injection device 5 needs to rotate 90° once from above the operation panel 2 to reach the cleaning tank 7, and then rotate 90° in the same direction again to reach above the drying tank 8 for drying operation. In actual setting, the cleaning tank 7 and the drying tank 8 only need to be arranged on the loop where the liquid injection device 8 rotates.

[0032] The liquid injection device 5 further includes a first motor 9, a connecting shaft 10, a fixing block 11, an electric telescopic rod 12 and a plurality of liquid injection heads 13.

[0034] And in this embodiment, four liquid injection heads 13 are provided on one liquid injection device 5. The fixing block 11 drives the liquid injection heads 13 to rotate through the connecting shaft 10 and the first motor 9. After the four liquid injection heads 13 complete the liquid injection operation in sequence, they rotate a certain angle to reach an adjacent liquid injection head 13 to perform the liquid injection operation again until all the liquid injection heads 13 on one fixing block 11 complete the liquid injection operation and need to be cleaned. Then the rotating shaft 3 is rotated to make this liquid injection device 5 rotate above the cleaning tank 7, and make an adjacent liquid injection device 5 that has completed the cleaning and drying operations rotate above the operation panel 2 to continue the liquid injection operation.

[0035] The cleaning tank 7 includes a water tank 14, a cleaning pool 15 and a plurality of nozzles 16. The cleaning pool 15 is arranged at the top end of the water tank 14, and a plurality of nozzles 16 are arranged around the inside of the cleaning pool 15.
