Abstract
Description
Technical Field
[0001] This utility model relates to the field of automated production technology of contact lenses, specifically a contact lens transfer device. Background Technology
[0002] In the process of separating contact lenses from the mold, the lenses need to be unloaded or transferred. Existing unloading or transfer equipment is bulky and has a long operating range, resulting in poor adaptability and low efficiency in unloading or transferring lenses, which does not meet the needs of use. There is an urgent need to provide an improved solution. Utility Model Content
[0003] The purpose of this invention is to provide a contact lens transfer device that is small in size, has a short working stroke, high efficiency in unloading or transferring lenses, and can be flexibly combined with other equipment.
[0004] To achieve the above objectives, this utility model provides the following technical solution;
[0005] A contact lens retrieval transfer device includes a first retrieval mechanism, a second retrieval mechanism, a lens storage mechanism, and a retrieval displacement driving mechanism for moving the first and second retrieval mechanisms.
[0006] During operation, the first lens-retrieving mechanism removes the lens from the mold and places it on the lens temporary storage mechanism; the second lens-retrieving mechanism removes the lens from the lens temporary storage mechanism.
[0007] Furthermore, it also includes an anti-collision mechanism; the anti-collision mechanism includes a trigger plate installed on the second wafer picking mechanism and a photoelectric sensor installed on the first wafer picking mechanism; the photoelectric sensor is signal-connected to the wafer picking displacement drive mechanism;
[0008] When the first wafer picking mechanism approaches the second wafer picking mechanism, the trigger plate activates the photoelectric sensor, which transmits a collision signal to the wafer picking displacement drive mechanism. The wafer picking displacement drive mechanism then drives the first and second wafer picking mechanisms to pause.
[0009] Furthermore, the first wafer picking mechanism includes a first connecting plate that is driven to the execution end of the wafer picking displacement driving mechanism, a first wafer picking lifting driving mechanism mounted on the first connecting plate, and a first wafer picking fixture that is driven to the execution end of the first wafer picking lifting driving mechanism.
[0010] During operation, the lens picking displacement drive mechanism drives the first lens picking lifting drive mechanism to a designated position, and then the first lens picking lifting drive mechanism drives the first lens picking fixture to pick up and place the lens.
[0011] Furthermore, the first wafer-retrieving fixture includes a nozzle mounting bracket that is driven and connected to the execution end of the first wafer-retrieving lifting drive mechanism, and a plurality of nozzles disposed on the nozzle mounting bracket.
[0012] Furthermore, the lens storage mechanism includes a storage rack and multiple lens fixing fixtures mounted on the storage rack.
[0013] Furthermore, the temporary storage rack is located within the common working stroke area of the first and second film retrieval mechanisms.
[0014] Furthermore, a lens hopper is also provided at the unloading end of the second lens taking mechanism.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] This contact lens retrieval and transfer device uses a first and second lens retrieval mechanism in conjunction with a lens storage mechanism. This results in a short working stroke for both mechanisms, enabling rapid lens retrieval and placement, facilitating quick lens transfer and improving operational efficiency. The first and second mechanisms are mounted using the same lens displacement drive mechanism, making the structure compact. In use, this contact lens retrieval and transfer device can be flexibly integrated with other equipment, demonstrating its high practicality. Attached Figure Description

[0018] Figure 2 This is a three-dimensional structural schematic diagram of the present invention from another perspective. Detailed Implementation
[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0020] refer to Figure 1-2 As shown, a contact lens retrieval transfer device includes a first retrieval mechanism 630, a second retrieval mechanism 620, a lens storage mechanism 640, and a retrieval displacement drive mechanism 610 for moving the first retrieval mechanism 630 and the second retrieval mechanism 620. The first retrieval mechanism 630 removes the lens from the mold and places it on the lens storage mechanism 640. The second retrieval mechanism 620 removes the lens from the lens storage mechanism 640.
[0021] This contact lens retrieval and transfer device uses a first lens retrieval mechanism 630 and a second lens retrieval mechanism 620 in conjunction with a lens storage mechanism 640. This results in a short working stroke for both mechanisms, allowing for fast lens retrieval and placement, facilitating rapid lens transfer and improving operational efficiency. The first and second mechanisms are mounted using the same lens retrieval displacement drive mechanism 610, making the structure compact. In use, this contact lens retrieval and transfer device can be flexibly integrated with other equipment, demonstrating its high practicality.
[0022] In this embodiment, an anti-collision mechanism 650 is also included. The anti-collision mechanism 650 includes a trigger plate 651 mounted on the second wafer picking mechanism 620 and a photoelectric sensor 652 mounted on the first wafer picking mechanism 630. The photoelectric sensor 652 is signal-connected to the wafer picking displacement driving mechanism 610. When the first wafer picking mechanism 630 approaches the second wafer picking mechanism 620, the trigger plate 651 triggers the photoelectric sensor 652, and the photoelectric sensor 652 transmits a collision signal to the wafer picking displacement driving mechanism 610, which in turn drives the first wafer picking mechanism 630 and the second wafer picking mechanism 620 to pause.
[0023] Specifically, the anti-collision mechanism 650 is used to prevent the first wafer picking mechanism 630 and the second wafer picking mechanism 620 from colliding. When the wafer picking displacement drive mechanism 610 malfunctions or for other reasons, and drives the first wafer picking mechanism 630 and the second wafer picking mechanism 620 too close, triggering the photoelectric sensor 652, the signal can be transmitted to the wafer picking displacement drive mechanism 610 and / or the external industrial control host to control the pause of the first wafer picking mechanism 630 and the second wafer picking mechanism 620 to avoid collision.
[0024] In this embodiment, the first lens picking mechanism 630 includes a first connecting plate 631 that is driven to the execution end of the lens picking displacement driving mechanism 610, a first lens picking lifting driving mechanism 632 mounted on the first connecting plate 631, and a first lens picking fixture 633 that is driven to the execution end of the first lens picking lifting driving mechanism 632. After the lens picking displacement driving mechanism 610 drives the first lens picking lifting driving mechanism 632 to a designated position, the first lens picking lifting driving mechanism 632 drives the first lens picking fixture 633 to pick up and place the lens.
[0025] In this embodiment, the first lens-picking fixture 633 includes a suction nozzle mounting bracket that is driven and connected to the execution end of the first lens-picking lifting drive mechanism 632, and a plurality of suction nozzles disposed on the suction nozzle mounting bracket. Specifically, the first lens-picking lifting drive mechanism 632 may be a cylinder, and the first lens-picking fixture 633 may be a suction nozzle or a gripper, or other fixture capable of picking up and placing lenses.
[0026] In this embodiment, the technology and structure of the second lens taking mechanism 620 are similar to those of the first lens taking mechanism 630; therefore, they will not be described in detail. The difference is that the second lens taking mechanism 620 is used to remove the lens from the lens temporary storage mechanism 640 and transfer it to the receiving area.
[0027] In this embodiment, the lens storage mechanism 640 includes a storage rack 641 and a plurality of lens fixing fixtures 642 mounted on the storage rack 641. Specifically, the lens fixing fixture 642 is a suction nozzle.
[0028] In this embodiment, the temporary storage rack 641 is located within the common working stroke area of the first lens picking mechanism 630 and the second lens picking mechanism 620. Specifically, a lens hopper is also provided at the unloading end of the second lens picking mechanism 620.
[0029] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the scope defined by the spirit of this utility model.
