Specific embodiments

[0025] The technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0026] As Figures 1 - 5 shown, an eye drop filling device includes a fixed support 1 and a lifting plate 5. A conveyor belt 2 for conveying eye drop bottles is arranged on the fixed support 1. A support frame 3 for fixing the filling structure is arranged on the upper end surface of the fixed support 1. A lifting structure is cooperatively arranged between the support frame 3 and the lifting plate 5. The filling device further includes a filling structure and a protection structure;

[0027] The filling structure includes a liquid injection tank 6 and a driving plate 10. The liquid injection tank 6 is connected to the eye drop storage tank through a hose. The liquid injection tank 6 is fixedly connected to the lower end surface of the lifting plate 5. A liquid injection needle 7 is fixedly arranged on the lower end surface of the liquid injection tank 6. The liquid injection tank 6 is communicated with the liquid injection needle 7 and is equipped with a switch valve. The liquid injection tank 6 provides a fixed amount of eye drops and then flows out from the liquid outlet of the liquid injection needle 7 for filling. The driving plate 10 is fixedly connected to the outside of the liquid injection needle 7. The up and down movement of the liquid injection needle 7 can drive the driving plate 10 to move accordingly.

[0028] The protection structure includes a front protection shell 8 and a rear protection shell 9. Both the front protection shell 8 and the rear protection shell 9 are composed of L-shaped plates and side plates, and they are symmetrically arranged, capable of forming a protective cover with an open top. There are several elastic moving structures connected between the four corners on the side of the front protection shell 8 away from the rear protection shell 9 and the support frame 3. There are also several elastic moving structures connected between the four corners on the side of the rear protection shell 9 away from the front protection shell 8 and the support frame 3. Guide blocks 11 are fixedly connected to the inner side walls of the front protection shell 8 and the rear protection shell 9. The two guide blocks 11 are located on both sides of the liquid injection needle 7, and the corresponding ends of the guide blocks 11 are in contact with the driving plate 10. Among them, the guide block 11 is divided into two parts. The side close to the liquid injection needle 7 at the top is arc-shaped, and the bottom is vertical. A slope corresponding to the guide block 11 is also opened on the side of the driving plate 10 close to the guide block 11, facilitating the relative sliding between the driving plate 10 and the guide block 11.

[0029] In some specific implementation schemes, such as Figure 2 shown, in order to facilitate the filling of multiple eye drop bottles simultaneously, multiple liquid injection tanks 6 and liquid injection needles 7 are provided. The multiple liquid injection tanks 6 are equally spaced and fixedly connected to the bottom of the lifting plate 5. The liquid injection needles 7 are fixedly connected to the bottoms of the corresponding liquid injection tanks 6. The multiple liquid injection needles 7 all vertically penetrate the driving plate 10 and are fixedly connected to the driving plate 10. The lifting plate 5 facilitates the up and down adjustment of the multiple liquid injection needles 7, enabling the liquid injection needles 7 to extend into the corresponding eye drop bottles, facilitating the filling of the eye drop bottles.

[0030] In some specific implementation schemes, such as Figure 4 or Figure 5 shown, in order to facilitate the front protection shell 8 and the rear protection shell 9 to automatically open and close according to the lifting of the liquid injection needle 7, the elastic moving structures all include a fixed plate 12, a limiting rod 13, and a spring 14. The specific connection method of one set of elastic moving structures with the rear protection shell 9 is: the fixed plate 12 is fixedly connected to the side wall of the support frame 3, the limiting rod 13 is fixedly connected to the side of the rear protection shell 9 away from the front protection shell 8, the limiting rod 13 penetrates the corresponding fixed plate 12 and is slidably connected to the fixed plate 12. A spring 14 is connected between the fixed plate 12 and the rear protection shell 9. The spring 14 has the function of automatically resetting the front protection shell 8 or the rear protection shell 9. The connection method of the elastic moving structure with the front protection shell 8 is the same as the above and is symmetrically arranged.

[0031] In some specific embodiments, such as Figure 1 shown, in order to facilitate the up-and-down adjustment of the liquid injection needle 7, the lifting structure includes a hydraulic cylinder 4, the hydraulic cylinder 4 is fixedly connected to the lower end surface of the top plate of the support frame 3, the output end of the hydraulic cylinder 4 is fixedly connected with a lifting plate 5, and when the hydraulic cylinder 4 is started, the lifting plate 5 can drive the liquid injection tank 6 and the corresponding liquid injection needle 7 to lift and lower, so that the liquid outlet of the liquid injection needle 7 extends into the eye drop bottle.

[0032] In some specific embodiments, such as Figure 2 or Figure 5 shown, in order to prevent dust from entering from the top of the protective cover, the driving plate 10 is slidably connected to the inner wall of the protective cover, which can reduce the entry of dust into the protective cover.

[0033] In some specific embodiments, such as Figure 1 shown, in order to facilitate the separate placement of the eye drop bottles, a number of partition plates 15 are distributed on the outside of the conveyor belt 2, the liquid injection needle 7 is located in the middle between two adjacent partition plates 15, and the partition plates 15 play a role in dividing the upper end surface of the conveyor belt 2, so that the liquid injection needle 7 can extend into the corresponding eye drop bottle, which is convenient for multiple eye drop bottles to be perfused simultaneously, and thus can effectively improve the perfusion efficiency of the eye drop bottles.

[0034] In order to facilitate the understanding of this solution embodiment by those skilled in the art, the working principle of this solution will be briefly described below in combination with a specific application scenario:

[0035] During the actual use process, first start the conveyor belt 2, and then place the empty eye drop bottles on the conveyor belt 2. When the empty eye drop bottles move to the lower end of the liquid injection needle 7, the conveyor belt 2 stops conveying. At this time, extend the hydraulic cylinder 4, so that the lifting plate 5 drives a plurality of liquid injection tanks 6 and the corresponding liquid injection needles 7 to move downward. At the same time, the driving plate 10 also moves downward with the liquid injection needle 7. During the downward movement of the driving plate 10, it squeezes and pushes the guide blocks 11 on both sides, so that the front protective shell 8 and the rear protective shell 9 move to both sides, so that the liquid injection needle 7 can extend out of the protective cover and then into the eye drop bottle, and then the empty eye drop bottles are perfused with eye drops through the cooperation of the liquid injection tank 6 and the liquid injection needle 7. At the same time as the front protective shell 8 and the rear protective shell 9 move to both sides, the fixing plate 12 and the corresponding limiting rod 13 slide, so that the spring 14 is compressed.

[0036] After the filling is completed, the hydraulic cylinder 4 contracts, causing the lifting plate 5 to drive the liquid injection needle 7 to move upward. After the liquid injection needle 7 retracts into the protective cover, the driving plate 10 gradually releases the extrusion on the guiding block 11. During the reset process of the liquid injection needle 7, due to the resilience of the spring 14, the front protective shell 8 and the rear protective shell 9 gradually close. The driving plate 10 can also prevent dust from entering from the top, and can avoid the liquid injection needle 7 being exposed to the air for a long time without use, thus contaminating the eye drops.

[0037] The above has described several embodiments of the present invention in detail, but the embodiments of the present invention are not limited thereto and should not be considered as defining the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the application of the present invention should still fall within the scope covered by the patent of the present invention.
