DETAILED DESCRIPTION

[0057] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0058] Example 1

[0059] A rotary bottle filling mechanism, comprising: a turntable 1, a bottle holder 3, a bracket 4, a filling assembly, a filling assembly upgrading mechanism, a support column 7, a support plate 8, an empty bottle clamping assembly, a full bottle clamping assembly and a conveyor belt 11;

[0060] like Figure 1 As shown, on the upper surface of the turntable 1 near the edge of the turntable 1, a plurality of bottle holders 3 are arranged at equal angles in a circle, and tissue culture bottles that are not perfused with culture fluid and tissue culture bottles perfused with culture fluid are placed in the bottle holders 3;

[0061] A rotating shaft 2 is arranged at the center position below the rotating disk 1, and a motor is arranged at the lower end of the rotating shaft 2, and the lower end of the rotating shaft 2 is connected to the rotor of the motor; the motor rotates, driving the rotating shaft 2 to rotate, and the rotating shaft 2 drives the rotating disk 1 to rotate; the rotating disk 1 drives the bottle holder 3 to rotate;

[0062] In this embodiment, the arc length corresponding to the included angle between two adjacent bottle holder tubes 3 on the side of the turntable 1 is defined as a unit arc length; and the time for the turntable 1 to rotate one unit arc length is defined as a unit time.

[0063] A bracket is arranged on the right side of the turntable 1, and brackets 4 are arranged on both sides; a filling component lifting mechanism is arranged on the bracket 4; Figure 2 As shown, the lifting mechanism of the filling component is configured as a lifting rod 5; the base portion of the lifting rod 5 is vertically arranged on the bracket 4; three lifting rods 5 are arranged in this embodiment; the lifting rod 5 here can adopt a hydraulic lifting rod or an electric lifting rod; the control switch of the lifting rod 5 is communicated and connected to the PLC; the upper ends of the telescopic sections of the three lifting rods 5 are commonly connected to a laterally arranged connecting rod 501.

[0064] The filling assembly is arranged on the lifting section of the middle lifting rod 5 and is as close to the upper end of the lifting section as possible.

[0065] like Figure 3 As shown, the above-mentioned filling component includes: an arc plate 601, an extension plate 602, a filling nozzle 603 and a feed pipe 604; three extension plates 602 are provided; the middle extension plate 602 is provided on the lifting section of the middle lifting rod 5 near the tail end, as close to the upper end of the lifting section as possible; the middle position of the arc plate 601 is provided below the middle extension plate 602; another two extension plates 602 are provided near the two ends of the arc plate 601; a filling nozzle 603 is provided below the head ends of each of the three extension plates 602; and the feed pipe 604 is connected above the filling nozzle 603.

[0066] The angular spacing between the three filling nozzles 603 is equal to the angular spacing between the bottle holders 3 on the turntable 1 ; and each filling nozzle 603 can be directly opposite to a bottle holder 3 .

[0067] When perfusing the culture fluid, the lifting rod 5 drives the arc plate 601 to descend, so that the perfusion nozzle 603 extends into the mouth of the tissue culture bottle; the feed pipe 604 delivers the culture fluid to the perfusion nozzle 603; the culture fluid is perfused into the empty tissue culture bottle. The PLC system can control the lifting rod 5 to drive the perfusion nozzle 603 to rise or fall at the same position each time; and from the completion of a perfusion of the perfusion nozzle 603, the perfusion nozzle 603 rises, to the perfusion nozzle 603 descending again to extend into the mouth of the empty tissue culture bottle, this time interval is equal to three unit times. In this way, three tissue culture bottles can be perfused at one time, and when the next perfusion is performed, the perfusion can be performed right after the last three perfused tissue culture bottles.

[0068] like Figure 1As shown, a conveyor belt 11 is arranged on the left side of the turntable 1, the rear side of the conveyor belt 11 is the feeding side of the empty tissue culture bottles, and the front side is the discharging side of the filled tissue culture bottles; a support column 7 is arranged on the side of the conveyor belt 11 close to the turntable 1; two opposing support plates 8 are arranged on the support column 7; an empty bottle clamping assembly is arranged under one of the support plates 8; the empty bottle clamping assembly is arranged on the empty bottle feeding side;

[0069] A full bottle clamping assembly is arranged under another support plate 8; the full bottle clamping assembly is arranged on the full bottle discharging side; the empty bottle clamping assembly is used to clamp the empty tissue culture bottle on the conveyor belt 11 into the bottle seat tube 3 on the turntable 1; the full bottle clamping assembly is used to clamp the filled tissue culture bottle from the bottle seat tube 3 back to the conveyor belt 11.

[0070] like Figure 5 As shown, the above-mentioned empty bottle clamping assembly and full bottle clamping assembly include: a push rod 901, an electric control shaft 902, an L-shaped support rod 903, a sliding rod 904, a sliding vertical rod 905 and an electromagnetic clamping arc block 906; the base section of the push rod 901 is arranged below the support plate 8; the electric control shaft 902 is arranged at the end of the telescopic section of the push rod 901; the L-shaped support rod 903 is arranged below the electric control shaft 902; the sliding rod 904 is arranged at one end of the L-shaped support rod 903; a slide rail is arranged below the slide rod 904; two sliding vertical rods 905 are movably arranged on the slide rail; an electromagnetic clamping arc block 906 is respectively arranged at the lower end of the two sliding vertical rods 905.

[0071] The electromagnetic clamping arc block 906 is an arc-shaped structure. After the two electromagnetic clamping arc blocks 906 are brought close to each other, they can be clamped on the side wall of the tissue culture bottle to complete the clamping of the tissue culture bottle; and the two electromagnetic clamping arc blocks 906 can be relatively movable, so they can adapt to tissue culture bottles of various outer diameters. The electromagnetic clamping arc block 906 adopts the principle of electromagnets. The electromagnetic clamping arc block 906 is connected to the electric control component, and the electric control component makes the two electromagnetic clamping arc blocks 906 charged to generate a magnetic force that attracts each other. Its detailed principle and circuit structure belong to the prior art and will not be repeated here.

[0072] The above-mentioned push rod 901 can be a hydraulic telescopic rod or an electric telescopic rod, and the control switch of the push rod 901, the electric control shaft 902 and the electric control components of the electromagnetic clamping arc block 906 are all connected to the PLC; the push rod 901 extends, and the electromagnetic clamping arc block 906 descends to face the empty bottle on the conveyor belt 11 or the tissue culture bottle filled in the bottle seat tube 3; the electric control shaft 902 drives the L-shaped support rod 903 to rotate 180°; the electromagnetic clamping arc block 906 clamps the empty bottle to the top of the bottle seat tube 3, and puts the empty bottle into the bottle seat tube 3 after descending; or the electromagnetic clamping arc block 906 clamps the tissue culture bottle after perfusion and moves it to the top of the conveyor belt 11, and descends to place the tissue culture bottle after perfusion on the conveyor belt 11. Whenever a perfused tissue culture bottle is taken out, an empty bottle will be put in to replace it, and the rotation is continuous to achieve continuous perfusion.

[0073] The electromagnetic clamping arc block 906 of the empty bottle clamping assembly places an empty bottle, rises and rotates 180°, clamps a new empty bottle on the conveyor belt, and then rotates 180° back to the top of an empty bottle holder 3. This period of time is equal to one unit time.

[0074] Similarly, the electromagnetic clamping arc block 906 of the full bottle clamping assembly clamps a perfused tissue culture bottle, rotates 180°, reaches the conveyor belt 11, places the perfused tissue culture bottle on the conveyor belt 11, and then rotates back 180° to reach a new perfused tissue culture bottle on the turntable 1; this period of time is equal to one unit time.

[0075] The filling process is that the full bottle clamping assembly takes away a filled tissue culture bottle, leaving a bottle holder 3 empty, moves to the bottom of the empty bottle clamping assembly, and is immediately filled with an empty bottle; the cycle continues; the turntable 1 rotates from the empty bottle side to the full bottle side; the other tissue culture bottles on the turntable 1 complete the filling normally and turn to the full bottle side.

[0076] Example 2

[0077] Based on Example 1, in Example 1, after the perfusion nozzle 603 perfuses the culture solution into the empty tissue culture bottle, a small amount of culture solution may remain in the perfusion nozzle 603 and flow out from the perfusion nozzle 603 .

[0078] like Figure 4 As shown, in this embodiment, a valve plate 6031 is provided in the perfusion nozzle 603 to prevent the residual culture solution from flowing out of the perfusion nozzle 603 .

[0079] First, the filling nozzle 603 needs to be set as a hollow rectangular structure; a valve plate 6031 is hinged on the inner walls of the two opposite sides of the filling nozzle 603; an elastic member 6032 is set between the back of the valve plate 6031 and the inner wall of the filling nozzle 603; the elastic member 6032 here can be set as a spring, or can be set as other structures that produce elastic deformation after being subjected to force and return to the original state after the force disappears;

[0080] When the elastic member 6032 is not deformed, the two valve plates 6031 are in an inclined state, and the lower edges of the two valve plates 6031 are in contact, which is a closed state. Only when a large amount of culture fluid flows continuously, the valve plates 6031 are stressed and the two valve plates 6031 move downward, so that a gap is formed between the valve plates 6031, and the culture fluid can enter the tissue culture bottle normally. When the culture fluid delivery switch is turned off, no large amount of culture fluid passes through the perfusion nozzle 603, and the two valve plates 6031 are closed under the action of the elastic member 6032, so as to prevent a small amount of culture fluid remaining in the perfusion nozzle 603 from flowing out of the perfusion nozzle 603.

[0081] Example 3

[0082] Based on Example 1, the inner diameter of the bottle holder tube 3 is fixed; however, the outer diameter of the tissue culture bottle placed in the bottle holder tube 3 may not be fixed. The outer diameter of some tissue culture bottles may be smaller than the inner diameter of the bottle holder tube 3, and they may shake in the bottle holder tube 3, affecting the alignment of the filling nozzle 603 with the bottle mouth.

[0083] like Figure 6 As shown, in this embodiment, an airbag side wall 302 is arranged on the inner side of the cylinder wall of the bottle holder cylinder 3, close to the inner wall; an air filling tube 303 is arranged in the base of the bottle holder cylinder 3; the upper end of the air filling tube 303 is connected to the airbag side wall 302, and the lower end of the air filling tube 303 extends from the base of the bottle holder cylinder 3 and is connected to the air pump 304. The airbag side wall 302 is made of elastic material; the air pump 304 inflates the airbag side wall 302 through the air filling tube 303, so that the airbag side wall 302 is propped up and fixed on the outer wall of the tissue culture bottle; so that the tissue culture bottle remains centered and stable; in this way, the perfusion nozzle 603 can accurately face the bottle mouth. The control of the air pump 304 requires human participation; when an empty bottle is placed in the bottle holder cylinder 3, the air pump 304 is turned on; after the perfusion is completed, the air is discharged by the air pump 304.

[0084] Example 4

[0085] Based on Example 3, in Example 3, human intervention is required to control the air pump 304; however, the speed of emptying the bottle and continuous filling is very fast; human control is likely to result in omissions;

[0086] like Figure 6 As shown, in this embodiment, a pressure sensor 305 is embedded in the upper surface of the base of the bottle holder tube 3, and the pressure sensor 305 is connected to the PLC for communication;

[0087] When an empty bottle is placed in the bottle holder tube 3, the pressure sensor 305 will generate a sensing signal; when the culture fluid is poured into the empty bottle, the pressure sensor 305 will generate a second sensing signal, and this sensing signal is based on the first pressure value, and the pressure becomes larger;

[0088] In this way, when an empty bottle is placed in the bottle holder tube 3, the pressure sensor 305 feeds a first signal to the PLC; the PLC sends a control instruction to the air pump 304, and the air pump 304 inflates the airbag side wall 302; when the culture medium is perfused into the empty bottle, the pressure sensor 305 feeds a second signal to the PLC, and the PLC sends a control instruction to the air pump 304, so that the air pump 304 discharges the gas in the airbag side wall 302, so that the perfused tissue culture bottle can be easily taken out; in this way, the automatic inflation and exhaust of the airbag side wall 302 is achieved.
