DETAILED DESCRIPTION

[0032] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present application, and cannot be understood as a limitation of the present application.

[0033] The following disclosure provides many different embodiments or examples for implementing different structures of the present application. In order to simplify the disclosure of the present application, the components and settings of specific examples are described below. Of course, they are only examples and the purpose is not to limit the present application. In addition, the present application can refer to the same reference numerals and / or reference letters in different examples, and such repetition is for the purpose of simplification and clarity, and does not indicate the relationship between the various embodiments and / or settings discussed.

[0034] As Figures 1-5 shown, the present application provides a liquid medicine automatic filling equipment, a liquid medicine tray 8 is placed in a freeze dryer, and the liquid medicine automatic filling equipment comprises:

[0035] a rack 1;

[0036] a linear driving mechanism 2 installed in the rack 1;

[0037] a feeding pipe 3 installed on the linear driving mechanism 2; ​

[0038] The liquid medicine supply assembly 4 is connected with the input end of the feeding pipe 3.

[0039] The linear driving mechanism 2 is used to drive the output end of the feeding pipe 3 to move horizontally above the liquid medicine tray 8, and after the output end of the feeding pipe 3 moves horizontally above the liquid medicine tray 8 and the feeding pipe 3 is filled with liquid medicine, the liquid medicine supply assembly 4 supplies a fixed amount of liquid medicine to the feeding pipe 3.

[0040] The liquid medicine automatic filling equipment provided by the embodiment can automatically perform liquid medicine filling operation, and is preferably used for automatically filling liquid medicine into the liquid medicine tray 8 placed in the freeze dryer. After all the liquid medicine trays 8 are filled with liquid medicine, the freeze dryer of the embodiment can freeze the liquid medicine in the liquid medicine tray 8 to obtain freeze-dried powder. The material of the rack 1 of the embodiment is preferably stainless steel. The linear driving mechanism 2 of the embodiment can be a mechanism capable of driving a body to move along an axis, such as a pneumatic cylinder, an oil cylinder, a hydraulic cylinder or a lead screw module, which is installed in the rack 1. The feeding pipe 3 of the embodiment can be a liquid medicine delivery pipe, and the feeding pipe 3 of the embodiment is preferably a high-precision feeding pipe 3 provided by the patent with publication number CN117515425A, which is installed on the linear driving mechanism 2, so that the embodiment can move the output end of the feeding pipe 3 towards or away from the liquid medicine tray 8 by driving the feeding pipe 3 to move horizontally by the linear driving mechanism 2. The liquid medicine supply assembly 4 of the embodiment can be an existing liquid supply assembly, which is connected with the input end of the feeding pipe 3 and can adjust the amount of liquid medicine supplied. Since the liquid medicine supplied by the liquid medicine supply assembly 4 to the feeding pipe 3 will flow out of the output end of the feeding pipe 3, and the amount of liquid medicine supplied by the liquid medicine supply assembly 4 is the same as the amount of liquid medicine flowing out of the feeding pipe 3, i.e. the amount of liquid medicine supplied is the same as the amount of liquid medicine filled, therefore after the output end of the feeding pipe 3 moves horizontally above the liquid medicine tray 8 and the feeding pipe 3 is filled with liquid medicine, the embodiment can fill the same amount of liquid medicine into different liquid medicine trays 8 by supplying a fixed amount of liquid medicine to the feeding pipe 3 by the liquid medicine supply assembly 4. It should be understood that since the linear driving mechanism 2 of the embodiment can only drive the feeding pipe 3 to move horizontally, without external help, the embodiment can only fill liquid medicine into the liquid medicine trays 8 at the same height in the freeze dryer, and if it is necessary to fill liquid medicine into the liquid medicine trays 8 at different heights in the freeze dryer, after filling liquid medicine into the liquid medicine trays 8 at the same height, the embodiment needs to adjust the height of the linear driving mechanism 2 manually to adjust the height of the feeding pipe 3, so as to fill liquid medicine into the liquid medicine trays 8 at different heights in the freeze dryer.

[0041] The liquid medicine filling process of the liquid medicine automatic filling equipment provided by the embodiment can be: A1, controlling the liquid medicine supply assembly 4 to supply liquid medicine to the filling pipe 3 until liquid medicine flows out from the output end of the filling pipe 3, so that the filling pipe 3 is filled with liquid medicine; A2, controlling the linear driving mechanism 2 to drive the output end of the filling pipe 3 to move horizontally above the liquid medicine tray 8; A3, controlling the liquid medicine supply assembly 4 to supply a fixed amount of liquid medicine to the filling pipe 3; A4, analyzing whether the liquid medicine tray 8 at the current height is all filled with liquid medicine, if yes, ending, if not, returning to step A2. It should be understood that the embodiment is equivalent to automatically filling the liquid medicine tray 8 with liquid medicine through the cooperation of the linear driving mechanism 2 and the liquid medicine supply assembly 4. When step A2 is executed, the liquid medicine in the filling pipe 3 will not flow out from the output end of the filling pipe 3.

[0042] The liquid medicine automatic filling equipment provided by the present application can automatically fill the liquid medicine tray 8 in the freeze dryer with liquid medicine through the cooperation of the linear driving mechanism 2 and the liquid medicine supply assembly 4, i.e. the present application does not need to fill the liquid medicine by manual means, so the present application can effectively reduce the labor intensity and improve the liquid medicine filling efficiency and effectively solve the problem that when the liquid medicine is filled by manual means, the operator needs to be close to the liquid medicine tray 8, causing the pollutants such as bacteria or dust particles on the operator's body to fall into the liquid medicine tray 8, and the liquid medicine in the liquid medicine tray 8 and the final obtained freeze-dried powder are contaminated. In addition, the prior art needs the operator to hold the filling pipe 3 and drive the filling pipe 3 to move during the liquid medicine filling process, and during the driving of the filling pipe 3 to move, the filling pipe 3 may accidentally shake due to the hand shaking of the operator, and the liquid medicine in the filling pipe 3 may accidentally flow out, resulting in different loading amounts of different liquid medicine trays 8. Since the embodiment drives the filling pipe 3 to move by using the linear driving mechanism 2, the linear driving mechanism 2 will not shake when driving the filling pipe 3 to move, i.e. the moving precision of the filling pipe 3 driven by the linear driving mechanism 2 is greater than that of the filling pipe 3 driven by the operator, so the embodiment can effectively avoid the situation that the liquid medicine in the filling pipe 3 accidentally flows out due to accidental shaking of the filling pipe 3.
