In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to examples and accompanying drawings, and the exemplary embodiments and descriptions thereof are only used for explaining the present invention and are not meant to limit the present invention.

Fig. 1 and 8 show a batch filling apparatus for reagent bags, which comprises a funnel 3, a transmission assembly 5 and a filling assembly 6, which are sequentially arranged on a fixing frame 1 from top to bottom. Wherein, the transmission component 5 is fixedly arranged in the fixed frame 1, and the funnel 3 is used for storing the reagent bag 10 and is arranged above the fixed frame 1. The funnel 3 is fixed by the fixing frame 1 or other external fixing devices.

The reagent bag 10 has a structure as shown in fig. 10, the reagent bag 10 has two symmetrically arranged bag openings 10A, and the two bag openings 10A are both disposed on the same side of the reagent bag 10, so that reagents can be filled into the reagent bag 10 from any bag opening 10A. The bag opening 10A is made of PE plastic materials and has a fixed shape, and the arrangement of the bag opening 10A enables the gravity center of the reagent bag 10 to be closer to one side of the bag opening 10A when the reagent bag is in an empty bag state.

As shown in fig. 2, the bottom of the funnel 3 is provided with a funnel mouth 3A, and the funnel mouth 3A can enable the reagent bag 10 in the funnel 3 to slide out of the funnel mouth 3A. As arranged in fig. 5 to 7, the transfer unit 5 has an inclined plate 5A arranged obliquely; the swash plate 5A has a swash plate input end at a high level of the horizontal position and a swash plate output end at a low level of the horizontal position, respectively.

As shown in fig. 11, the filling assembly 6 includes a needle module 6A, a transmission module 6B, a bag fixing module 6C, and a base plate 6D. The needle head module 6A and the bag holding module 6C are disposed in a horizontal orientation on the front surface of the base plate 6D, and are disposed opposite to each other. The transmission module 6B is disposed on the back of the substrate 6D and is in first transmission connection with the needle module 6A.

When this application device uses, reagent bag 10 falls into transmission assembly 5 by funnel 3 through funnel mouth 3A, and the swash plate input by swash plate 5A does first slope slip to the swash plate output, it is fixed in the fixed module 6C of entering bag afterwards, because reagent bag 10's focus is close to sack 10A one side more, the event will constantly change the position of self at first slope slip in-process, sack 10A of reagent bag 10 can adjust to being close to swash plate output one side under the action of gravity, and keep this position to continue to do first slope slip, then fall into fixed module 6C and fix, syringe needle module 6A connects to approaching each other with bag fixed module 6C through first transmission afterwards, and accomplish the first grafting to sack 10A. The needle module 6A is externally connected with a reagent for filling through a pipeline connection, so that the reagent can be filled into the reagent bag 10 after the first insertion is completed.

In conclusion, the reagent bags 10 stored in the funnel 3 are placed in random directions in space, and when the reagent bags 10 are conveyed to the conveying assembly 5, the gravity center of the reagent bags is closer to the bag opening 10A, and the inclined plate 5A is obliquely arranged, so that the reagent bags 10 are matched with each other and under the action of gravity, the position of the reagent bags 10 is continuously changed in the first oblique sliding process on the inclined plate 5A, and finally the reagent bags are adjusted to be close to the output end of the inclined plate on the set side of the bag opening 10A, and then all the reagent bags 10 enter the bag fixing module 6C to be fixed in the uniform position, so that the needle module 6A can conveniently perform first inserting and filling of the reagents, and the positions of the reagent bags 10 are not manually adjusted.

In some embodiments, the present apparatus is further provided with a sorter assembly 4. As shown in fig. 1, the sorting assembly 4 is fixed on the top plate of the fixing frame 1 in a plugging way and is positioned between the hopper 3 and the transmission assembly 5. As shown in fig. 3 and 4, the sorting assembly 4 includes a sorting housing 4A, a sorting body 4B, and a sorting motor 4C, all of which are of a revolving structure. The sorting housing 4A covers the sorting body 4B, and the sorting body 4B is in shaft connection with the sorting motor 4C; the sorting housing 4A is provided with an input port 4A1 on the top surface and an output port 4A2 on the bottom surface, the input port 4A1 is in butt joint with the funnel port 3A as shown in fig. 2, and the output port 4A2 is in butt joint with the inclined plate input end of the inclined plate 5A. A plurality of sorting cavities 4B1 are annularly arranged in the sorting body 4B; each sorting chamber 4B1 is capable of receiving one reagent bag 10. The sorting body 4B can sort rotation by the sorting motor 4C, and the center of rotation is located in the vertical direction.

In particular, as shown in fig. 4, when the sorting motor 4C is started, the sorting body 4B starts to perform sorting rotation, and during the sorting rotation, when the sorting chamber 4B1 is opposite to the input port 4a1, a reagent bag 10 in the hopper 3 can be picked up and enter the sorting chamber 4B1, and as the sorting rotation progresses, when the sorting chamber 4B1 is opposite to the output port 4a2, the reagent bag 10 in the sorting chamber 4B1 can be fed onto the inclined plate 5A. When the sorting motor 4C stops, the entire sorting rotation stops, and the conveyance of the reagent pack 10 by the entire apparatus is interrupted. It can be seen that the setting of letter sorting subassembly 4 can control the transmission rate of whole device reagent bag 10, when the transmission was too fast, can block transmission process through the speed that reduces the letter sorting rotation or the work that stops letter sorting subassembly 4, prevent to appear the jam of reagent bag 10 and pile up the phenomenon on transmission subassembly 5 and filling subassembly 6, and when transmission rate was lower, can make transmission rate accelerate through improving letter sorting self-transmission speed again, play the control to whole device transmission rate.

Further, as shown in fig. 1 and 5, two hoppers 3, two sorting assemblies 4 and two inclined plates 5A are respectively arranged side by side and symmetrically; the two inclined plates 5A are combined into a V-shaped plate, and the V-shaped plate is provided with inclined plate input ends which belong to the two sides of the top part and inclined plate output ends which are positioned at the bottom part.

As shown in fig. 5 to 7, the transfer unit 5 further includes a riser 5C. The front surface of the sloping plate 5A is provided with support plates symmetrically arranged along the sloping direction, a first transmission channel 5A1 is formed between the support plates, and the input end and the output end of the sloping plate are respectively positioned at two ends of the first transmission channel 5A 1. The vertical plate 5C is arranged below the output end of the inclined plate along the vertical direction, so that the transmission assembly 5 is in a Y-shaped structure; the riser 5C amalgamates each other and forms the passageway chamber along vertical direction, and the symmetry midplane in passageway chamber is equipped with the baffle and separates the passageway chamber for two second transmission path 5C1 along vertical direction. The second transmission channel 5C1 has a vertical input end and a vertical output end; the vertical input end of the second transfer channel 5C1 terminates at the sloping plate output end of the first transfer channel 5a1, and the vertical output end of the second transfer channel 5C1 is located directly above the bag holding module 6C.

The arrangement is such that the transfer set 5 has a maximum throughput of two reagent bags 10 at a time. As shown in fig. 1, the sorting modules 4 pick up a reagent bag 10 from each corresponding hopper 3 and transfer it to the transport module 5, specifically to a first transport path 5a1, and the reagent bag 10 slides on the first transport path 5a1 in a first inclined manner and merges into the vertical plate 5C, then enters the second transport path 5C1, and falls into the bag holding module 6C together in a free-fall movement in the second transport path 5C 1.

In some embodiments, as shown in fig. 5-7, the transmission assembly 5 further includes a vibration module 5B. The vibration module 5B is arranged on the back of the inclined plate 5A and comprises a vibration wheel 5B1 and a vibration motor 5B 2; the two sides of the inclined plate 5A are provided with support lugs extending towards the back in pairs, and the two ends of the vibration wheel 5B1 along the axial direction are respectively connected with the support lugs in a rotating way; the vibration motor 5B2 is coupled to the end of the vibration wheel 5B 1; the circumferential surface of the vibration wheel 5B1 is provided with a plurality of convex teeth along the axial direction. The inclined included angle of the inclined plate 5A is 10-20 degrees, and when the inclined plate 5A is static, the reagent bag 10 is self-locked and is static on the inclined plate 5A by means of the friction force of the surface of the inclined plate.

The arrangement is to consider that when the reagent bags 10 perform the first tilting motion on the tilting plate 5A, if the reagent bags slide only by the gravity of the tilting plate 5A, the tilting plate 5A needs enough included angle and stroke length, so that the space occupation of the whole device is increased, and the time for performing the first tilting motion on the corresponding reagent bags 10 is longer, so that the transmission speed of the whole device is reduced. Therefore, by adopting the design, the size of the included angle and the stroke length of the inclined plate 5A can be properly reduced by arranging the vibration module 5B. When the vibration type inclined plate vibrating device is used, the vibration motor 5B2 is started to drive the vibration wheel 5B1 to rotate, the convex teeth continuously touch the inclined plate 5A, and impact load is generated when the convex teeth touch the inclined plate 5A to continuously vibrate the inclined plate 5A. The reagent bag 10 on the inclined plate 5A can be continuously shaken when the inclined plate 5A shakes, so that the reagent bag can be firstly obliquely slid by shaking, and the body position of the reagent bag 10 can be changed in the shaking process, so that the reagent bag 10 keeps the bag opening 10A side to be obliquely downward.

In some embodiments, as shown in FIG. 8, the spatial coordinate system XYZ is set to include X, Y, and Z axes in a pairwise orthogonal relationship. Wherein the second transfer channel 5C1 is arranged along the Z-axis. The pouch fixing module 6C includes a pouch fixing plate 6C1, a cylinder assembly 6C2, an L-shaped movable plate 6C3, and a fixing plate 6C4 shown in fig. 14; the needle head module 6A and the bag fixing module 6C are fixed to the front surface of the base plate 6D, and are respectively located at two ends of the base plate 6D along the Y-axis direction.

The end face of the bag fixing plate 6C1 is provided with a fixing plate 6C4, an L-shaped movable plate 6C3 and a cylinder assembly 6C2 which are arranged in sequence along the X-axis direction. The L-shaped movable plate 6C3 has a transverse plate and a vertical plate, the vertical plate is fixedly connected with a piston rod of the cylinder assembly 6C2, the vertical plate, the transverse plate and the fixed plate 6C4 of the L-shaped movable plate 6C3 surround a bag-forming accommodating cavity, the bag-forming accommodating cavity is right below the second conveying channel 5C1 as shown in FIG. 9, and the reagent bag 10 can fall into the bag-forming accommodating cavity through the second conveying channel 5C 1.

As described above, the transport unit 5 can output two reagent bags 10 at a time, so that the bag housing chamber can house two reagent bags 10 arranged side by side in the X-axis direction at a time. The cylinder assembly 6C2 can push the vertical plate to move along the X-axis direction, thereby changing the volume of the bag accommodating cavity and enabling the bag accommodating cavity to complete the fixation of the reagent bag 10.

As shown in FIG. 17, a plane of the reagent bag holding member 6A2 and the needle tube 6A3 is arbitrarily cut in a direction perpendicular to the Y-axis, and a first connecting line O1 at the center of the cross section of the reagent bag holding member 6A2 and a second connecting line O2 at the center of the cross section of the needle tube 6A3 are formed on the plane. It can be seen that the first line O1 and the second line O2 bisect each other perpendicularly and bisect each other, and as can be seen from fig. 17, fig. 15, and fig. 16 taken together, the two reagent bag positioners 6a2 and the two needle tubes 6A3 together form a diamond arrangement, with the two reagent bag positioners 6a2 located at the upper and lower ends of the diamond arrangement and the two needle tubes 6A3 located at the left and right ends of the diamond arrangement.

The outer peripheral surface of the pocket 10A may be an elliptic cylindrical surface as shown in fig. 16 and 17. As shown in fig. 11, 15, 16 and 17, the needle module 6A can move along the Y-axis direction through the first transmission connection, and approach the bag fixing module 6C, so that the two reagent bag positioning pieces 6A2 are inserted into the gap between the two reagent bags 10, and the two bag openings 10A are located between the two reagent bag positioning pieces 6A2, so that the outer peripheral surfaces of the two reagent bag positioning pieces 6A2, the inner side surfaces of the fixing plate 6C4 and the inner side surfaces of the riser of the L-shaped movable plate 6C3 form a tight fit with the outer peripheral surfaces of the two bag openings 10A, and the two bag openings 10A are fixed. Needle 6A3 is facing bag mouth 10A and the first insertion of bag mouth 10A is completed.

Thus, the needle module 6A can be filled with two reagent bags 10 at a time, and the reagent bag positioning member 6A2 is provided to form an effective fixing for the two reagent bags 10, especially the bag opening 10A, by matching with the structure of the bag opening 10 itself and the clamping effect of the L-shaped movable plate 6C3 and the fixed plate 6C 4.

In some embodiments, as shown in fig. 1 and 8, further comprises a housing 2; the cover shell 2 covers the filling assembly 6 inside; the top plate of the housing 2 is located between the conveying assembly 5 and the filling assembly 6, and is provided with a transition opening, and the reagent bags 10 sequentially pass through the second conveying channel 5C1 and the transition opening to enter a bag accommodating cavity surrounded by an L-shaped movable plate 6C3, a transverse plate of the L-shaped movable plate 6C3 and a fixing plate 6C 4. More preferably, as shown in fig. 14, the pouch securing module 6C further comprises a barrier 6C 5. The stopper 6C5 is fixed to the front end face of the fixing plate 6C4, and can block the side opening of the bag accommodating chamber to prevent the reagent bag 10 from slipping off.

It should be noted that the bottom plate of the housing 2 should also have an opening, and when the reagent bags 10 are filled, the bag fixing module 6C should be released from the fixing of the reagent bags 10, specifically, the L-shaped movable plate 6C3 and the fixing plate 6C4 are separated from each other, so that the reagent bags 10 fall out from the bottom of the bag accommodating chamber. Meanwhile, a gap is formed between the bottom of the housing 2 and the ground, and is used for placing a containing frame to contain the filled reagent bags 10, or a conveyor belt is arranged to convey the filled reagent bags 10 falling onto the conveyor belt to the next station, which is not described in detail herein.
