[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] refer to Figure 1-2 A contact lens mold transfer and limiting device includes: a transfer mechanism 1, a limiting mechanism 2, and a fixing mechanism 3. The transfer mechanism 1 has a transfer surface 11 for transferring the mold; the limiting mechanism 2 is disposed above the transfer surface 11 and has a limiting channel 21 whose width gradually decreases from the input end to the output end of the transfer surface 11, and the limiting channel 21 is straight near the output end of the transfer surface 11 to accurately guide several molds one by one; the fixing mechanism 3 is fixedly installed on the transfer mechanism 1 and connected to the limiting mechanism 2, and is used to suspend the limiting mechanism 2 above the transfer surface 11.

[0035] It is understandable that the transmission mechanism 1 can be a belt conveyor or a chain conveyor, and the transmission surface 11 can be the top surface of a transmission belt or chain, but is not limited to these. The limiting channel 21 is a component that guides the mold, for example, it can be composed of two long baffle structures or two rows of guide wheel groups, but is not limited to these. The fixing mechanism 3 is a component that suspends and fixes the limiting mechanism 2, for example, it can be directly welded to the transmission mechanism 1 by fixing blocks, or it can be fixed by fixing blocks with bolts, nuts and other fasteners, but is not limited to these. The width of the straight part of the limiting channel 21 can only be slightly larger than the width of the mold, so as to accurately guide the mold. When cooperating with the swing plate mechanism, the end of the limiting channel 21 is aligned with the station on the swing rod mechanism.

[0036] With this configuration, the fixing mechanism 3 can suspend and fix the limiting mechanism 2, preventing scratches on the transmission surface 11. The transmission surface 11 can transmit multiple molds, and the multiple molds can be gradually gathered together through the limiting channel 21, and finally accurately exported from the end of the limiting channel 21 to the work station of the plate-swinging mechanism.

[0037] In some embodiments, the limiting mechanism 2 further includes a first limiting plate 22 and a second limiting plate 23. The first limiting plate 22 is disposed above the transmission surface 11; the second limiting plate 23 is disposed at a distance above the transmission surface 11 on one side of the first limiting plate 22; a limiting channel 21 is formed between the first limiting plate 22 and the second limiting plate 23. It can be understood that since the limiting channel 21 is a convergence of components, the first limiting plate 22 and the second limiting plate can be configured in a figure-eight shape, or the first limiting plate 22 can be straight and the second limiting plate 23 can be inclined. In this way, when the mold is transmitted on the transmission surface 11, it is limited and guided by the first limiting plate 22 and the second limiting plate 23 on both sides.

[0038] Optionally, in some embodiments, the first limiting plate 22 is straight; the second limiting plate 23 includes a precision guide portion 231 and a convergence guide portion 232. The precision guide portion 231 is disposed on the side near the output end of the transmission surface 11 and is parallel to the first limiting plate 22; the convergence guide portion 232 is disposed on the side of the precision guide portion 231 away from the output end of the transmission surface 11 and is bent outward. It can be understood that the precision guide portion 231 is a straight plate structure parallel to the first limiting plate 22. The convergence guide portion 232 is a straight plate structure bent outward relative to the precision guide portion 231, or a straight plate structure inclined outward. In this way, the straight first limiting plate 22 can be disposed on the side of the transmission surface 11, facilitating cooperation with the fixing mechanism 3.

[0039] In some embodiments, the limiting mechanism 2 further includes a first bending plate 24 and a second bending plate 25 respectively disposed on opposite sides of the first limiting plate 22 and the gathering guide portion 232. The first bending plate 24 and the second bending plate 25 extend toward the center of the limiting channel 21, and at least one of the first bending plate 24 and the second bending plate 25 is disposed at intervals along the axial direction of the first limiting plate 22 and the gathering guide portion 232 and is staggered from each other. Here, the first bending plate 24 and the second bending plate 25 can be made of deformable metal sheet structure, so that the bending angle of the first bending plate 24 and the second bending plate 25 can be adjusted. The first bending plate 24 and the second bending plate 25 can also be detached, for example, by using embedded fit or screw locking, but not limited to these. With this configuration, the first bending plate 24 and the second bending plate 25 can initially gather the mold, and can play an anti-disorder effect when limiting and guiding a large number of molds at the same time.

[0040] In some embodiments, the transmission mechanism 1 further includes mounting panels 12 disposed on both sides of the transmission surface 11. The mounting panels 12 are structures for fixing the transmission surface 11 to both sides. Furthermore, the transmission mechanism 1 also includes several support members 13 disposed at the bottom of the mounting panels 12 for supporting the transmission mechanism 1. Here, the support members 13 can be support rod structures or square column structures, etc. The support members 13 can be used to raise the entire transmission mechanism 1 and fix it to other working platforms.

[0041] In some embodiments, the fixing mechanism 3 includes at least one horizontal positioning member 31 and a C-shaped connector 32. The horizontal positioning member 31 is disposed on the mounting panel 12 and connected to the first limiting plate 22, for suspending and fixing the first limiting plate 22 and adjusting its horizontal position. The C-shaped connector 32 is fitted onto both sides of the precision guide portion 231 and the first limiting plate 22, for fixing the precision guide portion 231 and the first limiting plate 22 together.

[0042] Understandably, several horizontal positioning components 31 can be spaced apart along the axial direction of the first limiting plate 22 to improve the stability of the first limiting plate 22. The connection between the C-shaped connector 32 and the first limiting plate 22 and the precision guide part 231 can be achieved by welding or screw connection, but is not limited to these methods. The horizontal positioning component 31 can adopt a sliding structure of slide rail and slider, and then lock the slider position with screws. It can also adopt a linear drive method, such as using a lead screw structure or linear motor, but is not limited to these methods.

[0043] With this configuration, since the precision guide section 231 and the first limiting plate 22 are parallel to each other and have the same width, using a C-shaped connector 32 in this part provides stability. The C-shaped connector 32 can fix the second limiting plate 23 and the first limiting plate 22 together without affecting the transmission of the mold within the limiting channel 21. The horizontal positioning component 31 can adjust the horizontal position of the entire limiting mechanism 2, thereby adjusting the horizontal position of the limiting channel 21 to correspond to different workstations on the swing arm mechanism.

[0044] In some embodiments, referring to references 2-3, the horizontal positioning member 31 includes: a base 311, a screw 313, and at least two tightening members 314. A vertical through slot 312 is formed on the base 311; the screw 313 passes through the through slot 312 and is connected to the first limiting plate 22; the two tightening members 314 are threaded onto the screw 313 and located on both sides of the base 311, for locking the position of the screw 313. With this configuration, the screw 313 can move horizontally within the through slot 312 and also vertically, thereby adjusting the height and horizontal position of the entire limiting mechanism 2. The two tightening members 314, after being tightened, clamp onto the base 311, locking the position of the screw 313, and thus locking the position of the limiting mechanism 2.

[0045] 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.
