It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0022] Please see Figures 1 to 12 This invention relates to a reagent tube packaging device, used in an embodiment of the present invention, for heat-sealing aluminum foil 001 onto reagent tube 003 (specifically, heat-sealing a sealing film 002 onto the opening of reagent tube 003). The packaging device includes a frame 10, a packaging support 20, a packaging device 30, a reagent tube fixture 40, and a positioning device 50. The packaging support 20 is mounted on the frame 10; the packaging device 30 is mounted on the packaging device 30; the reagent tube fixture 40 is placed on the frame 10 and located below the packaging device 30, and can hold several reagent tubes; at least two sets of positioning devices 50 are provided to position the reagent tube fixture 40 below the packaging device 30. The positioning device 50 positions the reagent tube fixture 40, and then the packaging device 30 moves down and heat-seales the aluminum foil 001 onto the reagent tube. The packaging device of this invention, by placing several reagent tubes on the reagent tube fixture 40, can simultaneously heat-seal multiple reagent tubes, improving heat-sealing efficiency. Please refer to the following for details. Figure 1 , 4-5. The aluminum foil 001 used in this utility model has a rectangular structure, and multiple sealing films 002 for the reagent tube openings have been formed on the top. Specifically, the entire aluminum foil 001 is stamped to form several sealing films 002. The shape of the sealing film 002 can cover the opening of the reagent tube, and it is usually round. However, in order to facilitate the subsequent tearing of the sealing film 002, an easy-tear part is usually provided on the round shape. The sealing film 002 and the aluminum foil 001 are not completely separated. After the aluminum foil 001 is formed on multiple reagent tubes, the sealing film 002 will be fixed on the reagent tubes, and the remaining aluminum foil 001 can be torn off.

[0023] Please refer to details. Figure 1-3 The packaging support 20 includes two guide posts 21 arranged side by side on the frame 10 and a fixing plate 22 disposed above the two guide posts 21. The frame 10 has a working plate 11, on which the packaging support 20, packaging device 30, positioning device 50 and reagent tube fixture 40 are disposed. The guide posts 21 are disposed on the surface of the working plate 11 through a first guide sleeve 23, and the fixing plate 22 is locked to the upper end of the guide posts 21 by bolts. Specifically, the bolts pass through the fixing plate 22 and are threadedly connected to the guide posts 21. The first guide sleeve 23 can also be locked to the working plate 11 by several bolts.

[0024] Please refer to details. Figure 1-3 The packaging device 30 includes a cylinder 31 mounted on the packaging support 20 with its output end facing downwards, a sliding plate 32 mounted on and slidably connected to the packaging support 20, a support frame 33 located below the sliding plate 32, and a heat-sealing plate 34 located below the support frame 33 for heat-sealing aluminum foil 001 onto the reagent tube. The sliding plate 32 is driven by the cylinder 31 to move vertically up and down, thereby moving the support frame 33 and the heat-sealing plate 34 vertically up and down. When heat sealing is required, the heat-sealing plate 34 is energized, and the cylinder 31 drives the heat-sealing plate 34 to approach the reagent tube fixture 40 above, heat-sealing the aluminum foil 001 onto the reagent tube. A second guide sleeve 321 is provided on the sliding plate 32, which is sleeved on the outside of the guide post 21 and slidably connected to the guide post 21.

[0025] Please refer to details. Figure 1-3 The support frame 33 includes several isolation columns 331 disposed below the sliding plate 32, an isolation plate 332 disposed below the isolation columns 331, and a heat-sealing plate 34 disposed below the isolation plate 332. The isolation columns 331 can be made of non-metallic material. This invention provides six isolation columns 331. The upper part is bolted to the isolation column 331 through the sliding plate 32, and the lower part is bolted to the isolation column 331 through the isolation plate 332.

[0026] Please refer to details. Figure 1-3The sliding plate 32 is also provided with a first hole for the wire to pass through, and a protective sleeve 35 is provided in the first hole. The first hole allows the wire of the heat-sealing plate 34 to pass through the sliding plate 32, and the protective sleeve 35 protects the wire to prevent it from being scratched.

[0027] Please refer to details. Figure 1-3 The positioning device 50 includes a positioning plate 51 mounted on the frame 10 and a locking member 52 for securing the positioning plate 51 to the frame 10. The positioning plate 51 is L-shaped and has an elongated hole 511 through which the locking member 52 passes. Specifically, each positioning plate 51 has two parallel elongated holes 511, and two locking members 52 are correspondingly provided. The locking members 52 can be bolts, which pass through the elongated holes 511 and are threadedly connected to the working plate 11 of the frame 10. The position of the positioning plate 51 can be adjusted through the elongated holes 511 to ensure that the reagent tube fixture 40 is kept below the heat-sealing plate 34.

[0028] Please refer to details. Figure 6 The reagent tube fixture 40 includes a base 41, a positioning seat 42, and a worktable 43. The base 41 provides support. At least one positioning seat 42 is provided and is mounted on the base 41. The worktable 43 is positioned above the base 41 and the positioning seat 42. The positioning seat 42 and the base 41 are detachably connected, and the worktable 43 and the base 41 are also detachably connected. The worktable 43 has several first placement holes 431 for placing reagent tubes. The positioning seat 42 has first positioning holes 421 corresponding to the first placement holes 431, and the base 41 has clearance positions 411 corresponding to the first positioning holes 421. After the liquid addition device of this invention completes the liquid addition, subsequent sealing treatment is required. Therefore, the reagent tube fixture 40 of this invention uses the positioning seat 42 to position the reagent tubes. When different reagent tubes need to be added or heat-sealed, only the corresponding positioning seat 42 needs to be replaced, achieving quick replacement and improving the applicability of the base 41.

[0029] Please refer to details. Figure 6 , 12 The base 41 has a mounting groove 412 for embedding the positioning seat 42, and a clearance position 411 is located at the bottom of the mounting groove 412. The first positioning hole 421 is mainly for adapting to the outer diameter of the reagent tube. The inner diameter of the first placement hole 431 and the clearance position 411 are both greater than or equal to the inner diameter of the first positioning hole 421. When it is necessary to place reagent tubes with different outer diameters, the matching positioning seat 42 can be directly replaced. That is, the inner diameter of the first positioning hole 421 of different positioning seats 42 is different, mainly to adapt to reagent tubes of different diameters. Of course, the clearance position 411 is a hole-like structure, and the inner diameter of the clearance position 411 and the placement position can be large enough to adapt to reagent tubes with different outer diameter specifications.

[0030] Please refer to details. Figure 6This utility model has two mounting slots 412 arranged side by side, with two rows of clearance positions 411 in each mounting slot 412; correspondingly, two positioning seats 42 are provided, with two rows of first positioning holes 421 and placement holes. A clearance groove 413 is provided on the upper surface of the short side of the base 41 to facilitate the removal of the workbench 43 from the base 41. Therefore, the reagent tube fixture 40 of this utility model has a 15*4 first placement hole 431, which can hold 60 reagent tubes. Thus, 60 reagent tubes can be packaged at once. During heat sealing, the reagent tubes are first placed on the reagent tube fixture 40, then two aluminum foils 001 are placed on top, and then sealed using the sealing device 30. The operation is simple. Furthermore, the sealing equipment of this utility model has a simple structure and low cost.

[0031] Please refer to details. Figure 1 , 6 8, 9. The workbench 43 includes a substrate 4301 and an anti-wear pad 4302 disposed on the substrate 4301. A first placement hole 431 penetrates the substrate 4301 and the anti-wear pad 4302. The substrate 4301 can be made of a metal plate, preferably an aluminum plate or an alloy plate, which is lighter overall and effectively reduces the overall weight of the fixture structure. The anti-wear pad 4302 is made of rubber or other materials to prevent damage to the surface of the reagent tube. The anti-wear pad 4302 is directly fixed to the surface of the substrate 4301, for example, by using glue.

[0032] Please refer to details. Figure 1 , 6 7. At least two first positioning posts 44 are provided on the base 41, and a second positioning hole 432 for cooperating with the first positioning posts 44 is provided on the worktable 43; several second positioning posts 45 are also provided on the worktable 43. Specifically, the second positioning posts 45 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 42. During heat sealing, two film layers are used accordingly. Each positioning seat 42 is provided with three second positioning posts 45. Combined with one of the first positioning posts 44, the four corners of the film layer can be accurately positioned. That is, the two first positioning posts 44 of this utility model can be set at two opposite corners of the worktable 43, and the six second positioning posts 45 can be arranged according to the actual situation. The two first positioning posts 44 can accurately position the worktable 43 and also facilitate the removal of the worktable 43. After the reagent tubes are heat-sealed, the worktable 43 can be removed from the base 41 and flipped over to remove all the reagent tubes with the membrane layer, achieving rapid unloading. The first positioning posts 44 can be used in conjunction with the second positioning posts 45 to position the four corners of the membrane layer, reducing the use of the second positioning posts 45.

[0033] Please refer to details. Figure 6 , 8The base 41 adopts a split structure, including a second support base 4101 located below and a first support plate 4102 disposed above the second support base 4101. The first support plate 4102 is locked to the second support base 4101 by several second bolts 4103. The second support base 4101 adopts an I-beam structure, which can greatly reduce the weight of the entire base 41 while ensuring the height of the entire base 41, thus reducing the handling effort. The second support base 4101 and the first support plate 4102 are made of the same material, both of which can be made of bakelite board.

[0034] Please see Figure 6 The reagent tube also has a protective cap, and a first placement slot 433 for placing the protective cap is provided on the outer side of the long side of the workbench 43. If the first positioning hole 421 on the positioning seat 42 is provided in two rows, a second placement hole 434 for placing the protective cap is also provided on the corresponding workbench 43.

[0035] Please see Figure 6 , 10 11, 12. To better install the positioning seat 42 into the mounting groove 412 of the base 41, a magnetic suction element 46 is provided at the bottom of the mounting groove 412, and an adsorption element 47 is provided at the bottom of the positioning seat 42 corresponding to the magnetic suction element 46. Specifically, the bottom of the mounting groove 412 is provided with a first groove 414 for placing the magnetic suction element 46, and the bottom of the positioning seat 42 is provided with a second groove 422 for embedding the adsorption element 47. The adsorption element 47 is made of a metal material that can be attracted by the magnetic suction element 46. The adsorption element 47 works in conjunction with the magnetic suction element 46 to prevent the positioning post from falling out of the mounting groove 412. The bottom of the first groove 414 is also provided with a first through hole 415 to facilitate the removal of the positioning seat 42 from the mounting groove 412. The magnetic suction element 46 adopts a ring structure. When it is necessary to replace the base 41, a cylindrical structure can be used to pass through the first through hole 415 to remove the positioning seat 42 from the mounting groove 412. Further configuration: the magnetic component 46 can be glued or fitted with an interference fit, the fixing method of the adsorption component 47 can be similar to that of the magnetic component 46, and the material of the positioning seat 42 is the same as that of the base 41.

[0036] The working principle of this packaging equipment is as follows: First, adjust the position of the positioning device 50 according to the required location, place several reagent tubes in the first placement slot 433 of the reagent tube fixture 40, then place two aluminum foils 001 corresponding to the two positioning bases 41, and place the two side walls of the reagent tube fixture 40 against the positioning device 50. Start the sealing device 30, and the cylinder 31 drives the sliding plate 32 and the heat sealing plate 34 to move downward and close to the upper surface of the reagent tube fixture 40. Then the heat sealing plate 34 works to heat seal the sealing film 002 at the opening of the reagent tube. After the heat sealing is completed, the cylinder 31 drives the sliding plate 32 and the heat sealing plate 34 to move upward, remove the reagent tube fixture 40, and put in the next set of reagent tube fixtures 40. The remaining aluminum foil 001 can be torn off the removed reagent tube fixture 40.

[0037] In summary, the packaging equipment of this utility model can simultaneously heat-seal multiple reagent tubes by placing several reagent tubes in the reagent tube fixture, thereby improving the heat-sealing efficiency.
