Description

Technical Field

[0001] This utility model relates to the technical field of reagent tube production equipment, and in particular to a reagent tube filling device. Background Technology

[0002] Reagents, also known as chemical reagents or pharmaceuticals, can be used for medical testing and diagnosis. Currently, some reagents are pre-filled into medical reagent tubes to avoid infection, making medical reagent tubes an indispensable auxiliary tool in medicine. Specifically, human blood can be collected and placed into the reagent tube to react with the reagent, so as to complete the task of testing and verifying the human body's health status.

The reagent tube filling production line of this utility model first places several empty reagent tubes on the reagent tube fixture 10, then places the reagent tube fixture 10 with reagent tubes on the sliding frame 23. After the sliding frame 23 moves the reagent tube fixture 10 to the designated position, the filling assembly works to fill the reagent tubes. Then, the filled reagent tube fixture 10 is removed, aluminum foil is laid on it, and it is placed on the second frame 31. The sealing device 33 is used to seal it, which can realize the simultaneous filling and sealing of multiple reagent tubes, thus improving the filling efficiency.

[0030] The liquid addition component 20 and the packaging component 30 in this invention can be arranged side by side, and a workstation is set between the two devices to facilitate the operator's standing and operation.

[0031] A groove 2111 is provided on the upper surface of the slide rail 211 along its long axis, and two sliding steps 2112 are provided on the inner side of the groove 2111 along its long axis.

The outer wall of the pulley 243 is provided with a sliding groove 2431 adapted to the sliding steps 2112. The liquid filling assembly of this utility model can be provided with two sets of liquid filling assemblies, corresponding to two reagent tube fixtures 10. By setting two sets of liquid filling assemblies 22 and two sets of reagent tube fixtures 10, liquid can be added to the reagent tubes on the two reagent tube fixtures 10 at the same time, improving the liquid filling efficiency. That is, more reagent tubes can be added at the same time, improving the liquid filling efficiency. At the same time, the sliding device 24 is provided to realize the smooth sliding of the sliding parts.

[0032] Please refer to details. Figure 2 , 3 The liquid filling device also includes a drive device 25, which drives the sliding frame 23 and the reagent tube fixture 10 to slide on the slide rail 211.

The specific installation method can use existing technology, and the driving principle of the drive motor 252 also uses existing technology, and it can achieve forward and reverse rotation. Before adding liquid, the reagent tube fixture 10 with reagent tubes is placed on the sliding frame 23. Then, the drive motor 252 works, moving the reagent tube fixture 10 to below the filling assembly 22. Since the reagent tube fixture 10 has several rows of reagent tubes, after one row has been filled, the sliding frame 23 is moved again to ensure that each row of reagent tubes on the reagent tube fixture 10 has been filled. Finally, the sliding frame 23 is reset, and the reagent tube fixture 10 can be removed and the prepared reagent tube fixture 10 placed back on top.

[0033] Please refer to details. Figure 3 , 56. Four sets of sliding devices 24 are provided, all located below the sliding frame 23 and near the four corners.

[0036] The encapsulation component 30 of this invention is used to heat-seal aluminum foil 002 onto reagent tube 001 (specifically, to heat-seal the sealing film onto the opening of the reagent tube). Specifically, the encapsulation component 30, by placing several reagent tubes in the reagent tube fixture 10, can simultaneously heat-seal multiple reagent tubes, improving heat-sealing efficiency. Please refer to the following for details. Figure 8 , 11-12. The aluminum foil used in this utility model has a rectangular structure, and multiple sealing films 003 for the reagent tube openings have been formed on the top. Specifically, the entire aluminum foil is stamped to form several sealing films 003. The shape of the sealing film can cover the opening of the reagent tube, usually in a circular shape. However, in order to facilitate the subsequent tearing of the sealing film, an easy-tear part is usually provided on the circular shape. The sealing film and the aluminum foil are not completely separated. After the aluminum foil is formed on multiple reagent tubes, the sealing film will be fixed on the reagent tubes, and the remaining aluminum foil can be torn off. The specific working principle is as follows: First, adjust the position of the positioning device 34 according to the required position, then place two aluminum foils corresponding to the two positioning bases 11 (at this time, the reagent tube fixture 10 has completed liquid addition), place the two side walls of the reagent tube fixture 10 against the positioning device 34, start the sealing device 33, the cylinder 331 drives the sliding plate 332 and the heat sealing plate 334 to move downward and close to the upper surface of the reagent tube fixture 10, then the heat sealing plate 334 works to heat seal the sealing film at the opening of the reagent tube. After the heat sealing is completed, the cylinder 331 drives the sliding plate 332 and the heat sealing plate 334 to move upward, remove the reagent tube fixture 10, and put in the next set of reagent tube fixtures 10. The remaining aluminum foil of the removed reagent tube fixture 10 can be torn off.

The sliding plate 332 is driven by the cylinder 331 to move vertically up and down, thereby moving the support frame 333 and the heat-sealing plate 334 vertically up and down. When heat sealing is required, the heat-sealing plate 334 is energized, and the cylinder 331 drives the heat-sealing plate 334 to approach the reagent tube fixture 10 above, heat-sealing the aluminum foil onto the reagent tube. A second guide sleeve 3321 is mounted on the sliding plate 332, and the second guide sleeve 3321 is sleeved on the outside of the guide post 321 and slidably connected to the guide post 321.

[0042] Please refer to details. Figure 1 , 213. The filling assembly 22 and the reagent tube fixture 10 of this utility model are both provided in two sets. During filling, the two sets of filling assemblies 22 can be used to simultaneously add liquid to the reagent tube fixture 10. Adding liquid to the reagent tube using the liquid adding tube 2214 is existing technology and will not be described in detail. The reagent tube fixture 10 includes a base 11, a positioning seat 12, and a worktable 13. The base 11 provides support. At least one positioning seat 12 is provided and is set on the base 11.

The positioning seat 12 is provided with first positioning holes 121 corresponding to the first placement holes 131. The base 11 is provided with clearance positions 111 corresponding to the first positioning holes 121. After the liquid addition component of this utility model completes the liquid addition, it needs to be sealed. Therefore, the reagent tube fixture 10 of this utility model is equipped with a positioning seat 12 for positioning the reagent tube. When different reagent tubes need to be added or heat-sealed, only the corresponding positioning seat 12 needs to be replaced, which can achieve quick replacement and improve the applicability of the base 11.

Specifically, the second positioning posts 15 are used to position the film layer so as to better heat seal the film layer to the opening of the reagent tube. This utility model is provided with two positioning seats 12. During heat sealing, two film layers are used accordingly. Each positioning seat 12 is provided with three second positioning posts 15, which, together with one of the first positioning posts 14, can accurately position the four corners of the film layer. That is, the two first positioning posts 14 of this utility model can be set at two opposite corners of the worktable 13, and the six second positioning posts 15 can be arranged according to the actual situation. The two first positioning posts 14 can accurately position the worktable 13 and also facilitate the removal of the worktable 13. After the reagent tubes are heat-sealed, the worktable 13 can be removed from the base 11 and flipped over to remove all the reagent tubes with the membrane layer, achieving rapid unloading. The first positioning posts 14 can be used in conjunction with the second positioning posts 15 to position the four corners of the membrane layer, reducing the use of the second positioning posts 15.

[0047] Please refer to details. Figure 13 , 15 The base 11 adopts a split structure, including a second support base 1101 located below and a first support plate 1102 disposed above the second support base 1101. The first support plate 1102 is locked to the second support base 1101 by several second bolts 1103. The second support base 1101 adopts an I-beam structure, which can greatly reduce the weight of the entire base 11 while ensuring the height of the entire base 11, thus reducing the handling effort. The second support base 1101 and the first support plate 1102 are made of the same material, both of which can be made of bakelite board.

[0048] Please see Figure 13 The reagent tube also has a protective cap, and a first placement slot 133 for placing the protective cap is provided on the outer side of the long side of the workbench 13. If the first positioning holes 121 on the positioning seat 12 are arranged in two rows, a second placement hole 134 for placing the protective cap is also provided on the corresponding workbench 13.

[0049] Please see Figure 13 , 17 18, 19. To better install the positioning seat 12 into the mounting groove 112 of the base 11, a magnetic suction element 16 is provided at the bottom of the mounting groove 112, and an adsorption element 17 is provided at the bottom of the positioning seat 12 corresponding to the magnetic suction element 16. Specifically, the bottom of the mounting groove 112 is provided with a first groove 114 for placing the magnetic suction element 16, and the bottom of the positioning seat 12 is provided with a second groove 122 for embedding the adsorption element 17. The adsorption element 17 is made of a metal material that can be attracted by the magnetic suction element 16. The adsorption element 17 works in conjunction with the magnetic suction element 16 to prevent the positioning post from falling out of the mounting groove 112. The bottom of the first groove 114 is also provided with a first through hole 115 to facilitate the removal of the positioning seat 12 from the mounting groove 112. The magnetic suction element 16 adopts a ring structure. When it is necessary to replace the base 11, a cylindrical structure can be used to pass through the first through hole 115 to remove the positioning seat 12 from the mounting groove 112. Further configuration: the magnetic component 16 can be glued or fitted with an interference fit, the fixing method of the adsorption component 17 can be similar to that of the magnetic component 16, and the material of the positioning seat 12 is the same as that of the base 11.

[0050] The reagent tube fixture 10 of this utility model is used as follows: First, select a suitable positioning seat 12 according to the outer diameter of the reagent tube and place it in the mounting groove 112. Due to the magnetic attraction 16, the positioning seat 12 is relatively stable on the base 11. Then, the second positioning hole 132 corresponds to the first positioning post 14. Place the worktable 13 on the base 11 and place the reagent tubes on the worktable 13 in sequence. That is, the reagent tubes pass through the placement hole and the first positioning hole 121 in sequence and are located in the clearance position 111 below. At the same time, the protective cap is located in the second placement hole 134 or the first placement groove 133. Then, fill the solvent through the liquid filling assembly and place the film layer corresponding to the second positioning post 15 and the first positioning post 14 on the worktable 13. Use the sealing machine to seal the film. After sealing, remove the worktable 13 from the base 11. Flip the worktable 13 to remove the sealed reagent tube. Of course, the entire fixture structure can also be flipped.

[0051] In summary, the reagent tube filling production line of this utility model first places several empty reagent tubes on a reagent tube fixture, then places the reagent tube fixture with the reagent tubes on a sliding frame. The sliding frame moves the reagent tube fixture to a designated position, whereupon the filling assembly adds liquid to the reagent tubes. Afterward, the liquid-filled reagent tube fixture is removed, covered with aluminum foil, and placed on a second frame for sealing using a sealing device. This allows for simultaneous liquid addition and sealing of multiple reagent tubes, improving filling efficiency. Furthermore, the liquid addition assembly and reagent tube fixture of this utility model have the following advantages: First, by setting two sets of filling assemblies and two sets of reagent tube fixtures, multiple reagent tubes can be added simultaneously, improving adding efficiency. Second, the sliding device ensures smooth sliding of the sliding components. Third, a single cover plate can fix multiple limiting sleeves, improving assembly efficiency. Fourth, the reagent tube fixture is equipped with positioning seats to accommodate reagent tubes of different specifications.
