Description

Technical Field

[0001] The utility model relates to the technical field of special commodity packaging, in particular to a lens packaging device. Background Art

[0002] In the production and processing of lenses, the packaging and transportation of lenses has always been a problem that has troubled the industry. Because lenses are a product that is very easy to wear, especially since most lenses are currently made of resin lenses, if there is wear, it may affect their use. In the prior art, most of the lenses are packaged individually in paper bags. First, the internal lenses cannot be directly observed, and repeated unpacking makes the paper bags unable to be sealed, and the lenses are easy to fall out during transportation and storage. Second, the lenses are easy to shift in the paper bags, and the friction caused by the displacement may cause the lenses to wear. At the same time, the protective ability of the paper bags is very low. After the lenses are displaced, adjacent lenses that were originally unable to contact may collide, which is likely to cause damage to the lenses. Utility Model Content

[0010] Furthermore, the clamping member includes a clamping groove and a clamping block, which are respectively arranged on the first module and the second module, and an arc groove for pressing is opened on one side of the first module or the second module where the clamping member is arranged.

[0011] Furthermore, a clamping protrusion is provided on the groove wall of the clamping groove, a guide surface is provided on the side of the clamping protrusion facing the clamping block, a clamping portion is provided on the free end of the clamping block, the clamping portion faces the clamping protrusion and abuts against the clamping protrusion, and the clamping portion and the clamping protrusion are used in conjunction with each other.

[0013] A rotating cavity is also provided in the first module, and a rotating shaft is provided in the rotating cavity. The axial direction of the rotating shaft is perpendicular to the sliding direction of the two guide sleeves. Among the edges on the other two sides of the elastic membrane, one edge is connected to the first module, and the other edge extends into the rotating cavity and is connected to the rotating shaft.

[0014] Furthermore, a ratchet mechanism is clamped at the end of the rotating shaft, and the rotation direction of the ratchet mechanism is from the side where the elastic membrane is connected to the first module to the side where the elastic membrane is connected to the rotating shaft.

[0015] Furthermore, a special-shaped groove and a connecting groove connecting the special-shaped groove to the outside are opened at the end of the rotating shaft.

[0016] Furthermore, a special-shaped locking block is provided at one end of the ratchet away from the special-shaped block, and an operating hole is opened on the first module, and the locking block can extend from the operating hole.

[0017] Furthermore, a universal locking hole is formed at one end of the locking block away from the ratchet.

[0018] Beneficial effects:

[0019] 1. When in use, place the lens between the elastic membranes on the first module and the second module, and snap the first module and the second module together through the snap-in block to achieve the storage of the lens. The elastic membrane is made of transparent PE, so the internal lens condition can be observed intuitively. The two elastic membranes are located on both sides of the lens, and the elastic membranes are elastic. After the lens is placed, the lens exerts a force on the elastic membrane, so that the lens and the elastic membrane are tightly pressed against each other, thereby fixing the position of the lens, so that the lens cannot be displaced in the elastic membrane, thereby avoiding lens wear caused by displacement friction. At the same time, the first module and the second module have a certain thickness, and even if the adjacent lenses are stacked, they will not contact each other, that is, no collision will occur, and the shapes of the first module and the second module are relatively regular, so they can be placed in order during transportation or storage, maximizing the use of transportation or storage space. The first module and the second module also provide a certain buffering effect in the event of an external collision, thereby improving the protection effect and reducing the loss of the lens caused by the external collision.

[0020] In summary, firstly, compared with other methods of packaging resin lenses, this solution has a better effect of protecting the lens film layer; secondly, using this solution to package the lenses can prevent scratches on the lenses during transportation; finally, using this solution makes transportation easier, and at the same time, the surface design and production of the lenses can be observed more intuitively.

[0021] 2. The first module and the second module are embedded with the edge of the elastic film by a pressing block and a pressing groove. The use distance of the elastic film is extended by the pressing method, so that the elastic film is tightened after pressing, thereby improving the fixing effect of the lens. The setting of the rounded corners avoids the generation of concentrated force on the elastic film, which causes damage to the elastic film, and reduces the wear of the elastic film during use. The setting of the arc groove separates the snap-in groove and the snap-in block by pressing the arc groove, thereby opening the first module and the second module and taking the lens. The setting of the snap-in protrusion and the snap-in block realizes the snap-in of the first module and the second module, wherein the setting of the guide surface facilitates the snap-in part to move to the bottom of the snap-in groove when snapping, and is restricted by the snap-in protrusion and cannot come out, thereby realizing the snap-in.
