[0036] Please see Figure 1 This product provides a rapid loading device for contact lens injection molds. The device includes an arranging device 10 for vibratingly arranging and conveying the injection molds. A transmission device 20, located on one side of the arranging device 10, is used to transport the injection molds. A clamping device 30, located at the output end of the transmission device 20, is used to clamp and move the injection mold. An injection device 40, located on one side of the clamping device 30, is used to inject liquid raw materials into the injection mold.

[0037] Understandably, the arranging device 10 is a component that sequentially arranges multiple injection molds before conveying them to the transfer device 20. For example, it can be a disc-type vibratory feeder or a straight-groove vibratory feeder, but is not limited to these. The transfer device 20 is a component that transfers injection molds between the arranging device 10 and the clamping device 30. For example, it can be a conveyor belt mechanism or a sliding conveyor mechanism, but is not limited to these. The clamping device 30 is a component that clamps and fixes the injection molds and then moves them. For example, it can be a clamping mechanism or an adsorption mechanism, but is not limited to these. The injection molding device 40 is a component that performs the injection molding operation. For example, it can be a single-stage injection molding device 40 or a two-stage injection molding device 40, but is not limited to these.

[0038] As can be seen from the above, this rapid injection mold loading equipment includes an arranging device 10 for arranging injection molds, which then transports the arranged molds to a conveying device 20. The conveying device 20 then transports the molds to a clamping device 30, which finally holds and transports the molds to the injection molding station, where the injection molding device 40 performs the injection molding process. Through the cooperation of the arranging device 10, the conveying device 20, and the clamping device 30, the equipment can automatically load the molds, improving processing efficiency while reducing labor intensity and labor costs.

[0039] As is known, in some embodiments, please refer to Figure 1 and Figure 3 The rapid loading equipment for contact lens injection molds also includes a mounting frame 50 that is positioned in front of the arranging device 10 and connects the arranging device 10 and the injection device 40; the clamping device 30 is mounted on the mounting frame 50.

[0040] Understandably, the mounting bracket 50 is a track for the clamping device 30 to move between the arrangement device 10 and the injection molding device 40. For example, it can be a square track or a circular track, but it is not limited to these.

[0041] As is known, in some embodiments, please refer to Figure 1 The arrangement device 10 includes: a vibrating table 11 for vibrating and arranging the injection mold; and a guide plate 12, which is arranged in a ring around the edge of the vibrating table 11 for guiding the injection mold out of the vibrating table 11.

[0042] Understandably, the vibration table 11 is a component that moves the injection mold and arranges the injection mold by vibration. For example, it can be a mechanical vibration table 11 or an electric vibration table 11, but it is not limited to these. The guide plate 12 is a component that moves the injection mold along the guiding direction of the guide plate 12. For example, it can be a curved guide plate 12 or a straight guide plate 12, but it is not limited to these.

[0043] With this setup, after the vibration table 11 automatically arranges the injection mold, the guide plate 12 guides the injection mold to move in a fixed direction, realizing automatic arrangement and transportation and reducing labor costs.

[0044] As is known, in some embodiments, please refer to Figure 1 The vibrating table 11 is an arc-shaped platform with a high center and gradually decreasing periphery; the guide plate 12 is provided with several openings 13.

[0045] Understandably, the guide plate 12 is located on the outermost ring of the vibrating table 11. Therefore, when vibration is required, the injection mold moves towards the outer guide plate 12. For example, the vibrating table 11 can be an arc-shaped platform with a high center that gradually decreases towards the outer ring, or it can be a unidirectional vibrating platform, etc., but it is not limited to these. After guiding the injection mold, the guide plate 12 needs to guide the injection mold out. For example, it can be by opening one opening 13 in the direction of injection mold movement, or by opening two openings 13, etc., but it is not limited to these.

[0046] With this configuration, when the vibration table 11 vibrates, the injection mold gathers and arranges itself towards the outer guide plate 12, and then moves along the guide plate 12 and is discharged from the outlet of the guide plate 12, thus achieving automatic material discharge.

[0047] As is known, in some embodiments, please refer to Figure 2 The transmission device 20 includes a conveyor belt 21, which is disposed at the output end of the arrangement device 10 and is used to receive the injection mold. A drive unit 22 is disposed on one side of the conveyor belt 21 and is used to drive the conveyor belt 21 to move.

[0048] Understandably, the conveyor belt 21 is a component that receives the injection mold led out by the guide plate 12. For example, it can be a flat conveyor belt or a flat conveyor belt with grooves on its surface, but it is not limited to these. The drive unit 22 is a component that drives the conveyor belt 21 to transport the injection mold. For example, it can be a motor 322 or a component consisting of gears and a pressure pump, but it is not limited to these.

[0049] As is known, in some embodiments, please refer to Figure 1 The clamping device 30 includes several grippers 31, which are disposed on one side of the transmission device 20 for clamping and fixing the injection mold. The number of grippers 31 is equal to the number of molds 41. A lifting mechanism 33 has its output end connected to the grippers 31 and is used to drive the grippers 31 to move up and down. A moving mechanism 32 has its output end connected to the lifting mechanism 33 and is used to move the grippers 31 left and right.

[0050] Understandably, the gripper 31 is a component that clamps the injection mold; for example, it could be a pneumatic gripper 31 or an electric gripper 31, but it is not limited to these. The moving mechanism 32 is a component that drives the injection mold to move left and right; for example, it could be a nut and screw mechanism or an electric push rod mechanism, but it is not limited to these. The lifting mechanism 33 is a component that drives the injection mold to rise and fall to remove the injection mold; for example, it could be an electrically driven lifting mechanism 33 or a hydraulically driven lifting mechanism 33, but it is not limited to these.

[0051] With this configuration, the gripper 31 holds the injection mold transported by the transmission device 20, the moving mechanism 32 transports the gripper 31 and the injection mold to the processing position, and the lifting mechanism 33 drives the injection mold into the injection station. Through fully automated transportation and processing, the labor intensity of workers is reduced and labor costs are reduced.

[0052] As is known, in some embodiments, please refer to Figure 4 The injection molding device 40 includes a raw material tank 44, located on one side of the arrangement device 10 and at the output end of the transmission device 20, for storing contact lens raw material. A mounting platform 43 is located on the side of the raw material tank 43 facing the clamping device 30, including a first mounting platform 431 and a second mounting platform 432. The first mounting platform 431 is positioned above the second mounting platform 432. A plurality of molds 41 are mounted on the second mounting platform 432 for clamping the injection molds; injection heads 42 are located below the first mounting platform and are mounted one-to-one with the molds, for extruding the raw material.

[0053] Understandably, the mounting platform 43 is a component that supports the mold 41 and the injection head 42. For example, it can be a support frame installed vertically or vertically, or a platform installed vertically or vertically. The mold 41 is a component that fixes the injection mold and stably aligns it with the injection head 42. For example, it can be a gripper or a clamping mechanism, but it is not limited to these.

[0054] With this configuration, mold 41 allows for quick and precise installation of the injection mold and alignment with the injection head 42, thereby improving injection efficiency.

[0055] As can be seen from the above, the pre-fitted injection mold is placed on the vibration table 11 of the arrangement device 10. The equipment is started, and the vibration table 11 vibrates, causing the injection mold to vibrate to the guide plate 12. The injection mold moves along the guide plate 12 and is led out through the opening 13 to the transmission device 20. The transmission device 20 transmits the injection mold to the clamping device 30. The clamping jaws 31 on the clamping device 30 pick up the injection mold and transport it to the injection device 40 through the moving mechanism 32. Finally, the lifting mechanism 33 puts the injection mold into the mold 41, and the injection head 42 injects the contact lens solution into the injection mold. Then, the clamping jaws 31 and the lifting mechanism 33 remove the injection mold and send it to the next processing step.

[0056] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
