Description

Technical Field

[0001] The utility model relates to the technical field of contact lens transportation, in particular to a transfer suction head for wet contact lenses. Background Technique

[0002] Contact lenses, also known as corneal contact lenses, are lenses worn on the cornea of the eyeball to correct vision or protect the eyes. Colored contact lenses are contact lenses. During the production process of contact lenses, transfer suction heads are generally required to transfer them to the next process.

[0003] The existing transfer suction heads for contact lenses are made of plastic, with a hard texture. In actual use, they are likely to cause deformation of contact lenses and may also lead to lens breakage. Therefore, some people have thought of setting the suction head to be made of silica gel to avoid damage to the lens. For example, the Chinese utility model patent with the application number 202223517308.2 specifically discloses a transfer suction head for wet contact lenses.

[0004] However, in actual use, people will find that the lens is sucked through the air intake channel of the suction head. However, since there is no air intake channel in the middle position of the suction head, the problem of lens loosening is likely to occur during the suction process. And when the suction head sucks the lens, the entire end of the suction head is likely to contact the lens, and its contact area is large, resulting in difficulty in the lens falling off. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a transfer suction head for wet contact lenses to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A transfer suction head for wet contact lenses includes a connecting head, a communicating part, a first suction head, and a second suction head. The connecting head is arranged at one end of the communicating part, and the other end of the communicating part is provided with the first suction head and the second suction head. The first suction head is located in the middle of the communicating part, and there are multiple second suction heads. Multiple convex columns corresponding to the second suction heads are evenly arranged on the outer side wall of the communicating part. Each second suction head is respectively located at the corresponding convex column. A connecting chamber is arranged in the middle of the connecting head. A first suction port is arranged on the first suction head, and a second suction port is arranged on the second suction head. Both the first suction port and the second suction port are communicated with the connecting chamber. By setting the suction head into the first suction head and the second suction head, with the first suction head arranged in the middle and multiple second suction heads, the suction force of the lens is improved. Setting multiple suction heads reduces the contact area with the lens, but there are many contact surfaces, which is convenient for the lens to fall off.

[0007] Preferably, an arc-shaped groove is arranged between every two adjacent convex columns, and the groove is tangent to the convex column to ensure the coherence between multiple convex columns.

[0008] Preferably, both the first suction head and the second suction head are cylindrical to reduce the contact area between each suction head and the lens.

[0009] Preferably, the ends of both the first suction head and the second suction head are arc-shaped to fit the lens.

[0010] Preferably, the second suction heads are arranged in an annular array to ensure the uniformity of the suction points.

[0011] Preferably, the connecting part, the first suction head, and the second suction head are all made of silica gel material, and the connecting part, the first suction head, and the second suction head are integrally formed.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] In the present utility model, the first suction head and the second suction head are arranged to simultaneously suck the lens, and the first suction head is located in the middle position to improve the suction force of the lens. Multiple suction heads are provided to increase the contact surface with the lens, and the contact area between each suction head and the lens is small, so as to facilitate the detachment of the lens, effectively improving the practicability of the device.

[0022] Please refer to Figures 1-4 , the present utility model provides a technical solution: an invisible lens wet sheet transfer suction head, including a connection head 1, a communication part 2, a first suction head 3 and a second suction head 4. The connection head 1 is arranged at one end of the communication part 2, and the other end of the communication part 2 is provided with the first suction head 3 and the second suction head 4. The first suction head 3 is located in the middle of the communication part 2. There are multiple second suction heads 4, and a plurality of convex columns 201 corresponding to the second suction heads 4 are evenly arranged on the outer side wall of the communication part 2. Each second suction head 4 is respectively located at the corresponding convex column 201. A connection chamber 101 is arranged in the middle of the connection head 1. A first suction port 301 is arranged on the first suction head 3, and a second suction port 401 is arranged on the second suction head 4. Both the first suction port 301 and the second suction port 401 are communicated with the connection chamber 101.

[0023] By setting the suction head into the first suction head 3 and the second suction head 4, and the first suction head 3 is arranged in the middle, and there are multiple second suction heads 4 to improve the suction force of the lens. Setting multiple suction heads reduces the contact area with the lens, but there are many contact surfaces to facilitate the detachment of the lens.

[0024] Furthermore, an arc-shaped groove 202 is arranged between every two adjacent convex columns 201, and the groove 202 is tangent to the convex column 201 to ensure the coherence between multiple convex columns 201.

[0025] Furthermore, both the first suction head 3 and the second suction head 4 are cylindrical to reduce the contact area between each suction head and the lens.

[0026] Furthermore, the ends of both the first suction head 3 and the second suction head 4 are arc-shaped to fit the lens.

[0027] Furthermore, the second suction heads 4 are distributed in an annular array to ensure the uniformity of the suction points.

[0028] Furthermore, the connecting part 2, the first suction head 3, and the second suction heads 4 are all made of silicone material, and the connecting part 2, the first suction head 3, and the second suction heads 4 are integrally formed.

[0029] In summary, when the device is in use, the arc-shaped surfaces of the first suction head 3 and the second suction heads 4 are in contact with the contact lens, so that the lens covers the first suction port 301 and the second suction ports 401. At this time, the negative pressure generating device connected to the connecting head 1 continuously sucks air, causing a negative pressure in the connecting chamber 101, so that the lens is adsorbed on the first suction head 3 and the second suction heads 4. During the process, since the first suction head 3 is located in the middle position to increase the suction force of the lens, multiple suction heads are provided to increase the contact surface with the lens, and the contact area between each suction head and the lens is small. After the transfer is completed, the negative pressure generating device stops sucking air, causing the lens to detach.

[0030] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
