Description

Technical Field

[0001] The present invention relates to the technical field of sample detection, and particularly relates to a reagent bottle loading and unloading device and an analyzer. Background Art

[0002] An analyzer is used to detect and analyze samples in reagent bottles. Analyzers usually have a reagent tray. Currently, the loading and unloading of reagent bottles in the reagent tray require manual placement of the reagent bottles into the reagent tray or manual removal of the waste reagent bottles from the reagent tray. This not only consumes a large amount of manpower and loading and unloading time, but also when the detection volume is large and during the peak detection period, if it is necessary to add or replace reagent bottles in the reagent tray, the entire analyzer needs to be shut down to perform the reagent bottle loading and unloading operation, which affects the detection efficiency and delays the sample detection and analysis process. Summary of the Invention

[0039] The present invention provides a reagent bottle loading and unloading device 100.

[0040] As Figures 1 to 6As shown in the figure, the reagent bottle loading and unloading device 100 of this embodiment includes a bottom plate 10, a transportation mechanism 20, a rotating mechanism 30, and a grasping mechanism 40. A vertical plate 11 is provided on the bottom plate 10, and a plurality of loading and unloading openings 12 are formed in the bottom plate 10; the transportation mechanism 20 includes a base 21, a tray 22, and a moving drive assembly 23. The base 21 is arranged side by side with the bottom plate 10. The tray 22 is slidably provided on the base 21, and a buffer rack 24 for holding a plurality of reagent bottles is placed in the tray 22. The moving drive assembly 23 is used to drive the tray 22 to slide along the base 21; the rotating mechanism 30 includes a swing arm 31 and a rotation drive assembly 32. The swing arm 31 is rotatably connected to the vertical plate 11, and the rotation drive assembly 32 is used to drive the swing arm 31 to rotate relative to the vertical plate 11; the grasping mechanism 40 includes a jaw 41 and a clamping drive member 42. The jaw 41 is connected to the swing arm 31, and the clamping drive member 42 is used to drive the jaw 41 to grasp the reagent bottle and pass through the loading and unloading opening 12.

[0041] The reagent bottle loading and unloading device 100 of this embodiment can be applied to load and unload the reagent bottles in the reagent tray 200 in an analyzer. Specifically, the bottom plate 10 is spaced above the reagent tray 200. A plurality of loading and unloading openings 12 are formed in the bottom plate 10. The base 21 is arranged side by side with the bottom plate 10. A tray 22 is provided on the base 21. A buffer rack 24 is placed in the tray 22. A plurality of reagent bottles are contained in the buffer rack 24. The vertical plate 11 is provided on the bottom plate 10. The swing arm 31 is installed on the vertical plate 11 and can rotate relative to the swing arm 31. A jaw 41 is connected to the end of the swing arm 31 away from the vertical plate 11.

[0042] When loading reagent bottles is required, first place the reagent bottles on the buffer rack 24 and place the buffer rack 24 on the tray 22. The moving drive assembly 23 drives the tray 22 to move along the base 21, so that the tray 22 drives the buffer rack 24 and the reagent bottles to move to a position close to the vertical plate 11. Then the rotation drive assembly 32 drives the swing arm 31 to rotate relative to the vertical plate 11, so that the swing arm 31 drives the jaw 41 to move above the buffer rack 24. The clamping drive member 42 drives the jaw 41 to grasp the reagent bottle from the buffer rack 24. Then the rotation drive member 321 drives the swing arm 31 to drive the jaw 41 and the reagent bottle to move above any loading and unloading opening 12. The jaw 41 drives the reagent bottle to pass through the loading and unloading opening 12 and places the reagent bottle in the reagent tray 200, completing the loading of the reagent bottle, saving a large amount of manpower and time.

[0043] Understandably, when it is necessary to unload the reagent bottle, the clamping jaw 41 passes through the loading and unloading port 12 and grabs the reagent bottle from within the reagent tray 200. The swing arm 31 drives the clamping jaw 41 and the reagent bottle to rotate above the buffer rack 24. The clamping jaw 41 places the reagent bottle in the buffer rack 24 and releases the reagent bottle. Then, the moving drive member 231 drives the tray 22 to move along the base 21, so that the tray 22 drives the buffer rack 24 and the reagent bottle to move to a position away from the vertical plate 11, facilitating the recycling of the reagent bottle and completing the unloading of the reagent bottle. The reagent bottle loading and unloading device 100 of this embodiment can drive the clamping jaw 41 to move to the buffer rack 24 or the loading and unloading port 12 through the swing arm 31, so that the clamping jaw 41 grabs the reagent bottle and drives the reagent bottle to pass through the loading and unloading port 12, thereby realizing the loading and unloading of the reagent bottle. There is no need to stop the analyzer when loading and unloading the reagent bottle, improving the detection efficiency, accelerating the sample analysis speed, and having a flexible and reliable structure.

[0044] In this embodiment, the reagent bottle loading and unloading device 100 further includes a lifting mechanism 50. The lifting mechanism 50 includes a transfer seat 51 and a lifting drive assembly 52. The transfer seat 51 is slidably installed on the vertical plate 11. The swing arm 31 is rotatably connected to the transfer seat 51. The lifting drive assembly 52 is used to drive the transfer seat 51 to lift along the vertical plate 11. As Figure 1 and Figure 2 shown, a transfer seat 51 is provided between the swing arm 31 and the vertical plate 11. The swing arm 31 is rotatably connected to the transfer seat 51 and can rotate relative to the transfer seat 51. The transfer seat 51 is slidably connected to the vertical plate 11 and can lift relative to the vertical plate 11. When the swing arm 31 drives the clamping jaw 41 to grab the reagent bottle from the buffer rack 24, the transfer seat 51 is located at a position close to the upper end of the vertical plate 11. Then, the swing arm 31 drives the clamping jaw 41 and the reagent bottle to move above the loading and unloading port 12. The transfer seat 51 drives the swing arm 31, the clamping jaw 41, and the reagent bottle to descend in the direction close to the loading and unloading port 12, so that the clamping jaw 41 drives the reagent bottle to pass through the loading and unloading port 12 and load the reagent bottle into the reagent tray 200, further improving the loading and unloading convenience.

[0045] Further, the lifting drive assembly 52 includes a lifting drive member 521, a first driving pulley 522, a first driven pulley 523, and a first synchronous belt 524. The first driving pulley 522 and the first driven pulley 523 are respectively arranged at both ends of the vertical plate 11. The first synchronous belt 524 is wound between the first driving pulley 522 and the first driven pulley 523. The first synchronous belt 524 is connected to the transfer seat 51. The lifting drive member 521 can drive the first driving pulley 522 to rotate, so as to drive the transfer seat 51 to lift along the vertical plate 11 through the first driven pulley 523 and the first synchronous belt 524.

[0046] As Figure 1 and Figure 2As shown, the lifting drive member 521 is disposed at the lower end of the vertical plate 11. The lifting drive member 521 is connected to the first driving pulley 522. The first driven pulley 523 is disposed at the upper end of the vertical plate 11. The first synchronous belt 524 is wound between the first driving pulley 522 and the first driven pulley 523 and is connected to the adapter base 51. When the lifting drive member 521 drives the first driving pulley 522 to rotate, the first driving pulley 522 drives the first synchronous belt 524 to rotate through the first driven pulley 523, so that the first synchronous belt 524 drives the adapter base 51 to move up and down along the vertical plate 11, enabling the adapter base 51 to drive the clamping jaws 41 and the reagent bottle to reciprocate in a direction close to or away from the loading and unloading port 12. This not only occupies a small space but also realizes the function of placing the reagent bottle into the reagent tray 200 from the loading and unloading port 12 or taking out the reagent bottle in the reagent tray 200 from the loading and unloading port 12, and the structure is flexible and reliable.

[0047] In this embodiment, the lifting mechanism 50 further includes a first guide rail 53 and a first slider 54. The first guide rail 53 is disposed on the vertical plate 11 and is in the same extending direction as the vertical plate 11. The first slider 54 is connected to the side of the adapter base 51 facing the vertical plate 11 and is in sliding contact and cooperation with the first guide rail 53. As Figure 1 and Figure 2 shown, when the adapter base 51 drives the swing arm 31 to move up and down along the vertical plate 11, the adapter base 51 synchronously drives the first slider 54 to slide along the first guide rail 53. The cooperation between the first guide rail 53 and the first slider 54 plays a role in guiding the up and down movement of the adapter base 51, improving the smoothness of the up and down movement of the adapter base 51 and enhancing the stability of the structure.

[0048] In the reagent bottle loading and unloading device 100 of this embodiment, a plurality of first optocouplers 55 are vertically and spacedly disposed on the vertical plate 11. A first baffle 56 is disposed on the adapter base 51, and a first induction groove for the first baffle 56 to extend into is formed on the first optocoupler 55. As Figure 1 and Figure 2 shown, at least three first optocouplers 55 are vertically and spacedly disposed on the vertical plate 11. A first baffle 56 is connected to the side of the adapter base 51 facing the vertical plate 11. The adapter base 51 can drive the first baffle 56 to move up and down relative to the vertical plate 11. When the adapter base 51 drives the first baffle 56 to extend into the first induction groove of the uppermost first optocoupler 55, it is determined that the clamping jaws 41 grab the reagent bottle and drive the reagent bottle away from the buffer rack 24; when the adapter base 51 drives the first baffle 56 to extend into the first induction groove of the middle first optocoupler 55, it is determined that the clamping jaws 41 grab the reagent bottle and place the reagent bottle into the buffer rack 24; when the adapter base 51 drives the first baffle 56 to extend into the first induction groove of the lowermost first optocoupler 55, it is determined that the clamping jaws 41 grab the reagent bottle and place the reagent bottle into the reagent tray 200 from the loading and unloading port 12, and the reliability of reagent bottle loading and unloading is high.

[0049] In this embodiment, the rotation driving assembly 32 includes a rotation driving member 321 and a rotation shaft 322. The rotation shaft 322 penetrates through the swing arm 31, and the rotation shaft 322 is connected to the rotation driving member 321 through a coupling 323. The rotation driving member 321 can drive the rotation shaft 322 to rotate, so that the rotation shaft 322 drives the swing arm 31 to rotate. Moreover, the grasping mechanism 40 further includes a mounting base 43. The mounting base 43 is slidably arranged at one end of the swing arm 31 away from the rotation shaft 322. The clamping jaw 41 is connected to the mounting base 43. An installation boss 431 is formed on one side of the mounting base 43 facing the swing arm 31. The installation boss 431 is arranged at intervals on the lower side of the swing arm 31, and a buffer elastic member 44 is clamped between the installation boss 431 and the swing arm 31.

[0050] As Figure 3 and Figure 4 shown, when it is necessary to place the reagent bottle in the reagent tray 200, the clamping jaw 41 grasps the reagent bottle, and the swing arm 31 drives the clamping jaw 41 to rotate above any loading and unloading port 12. The adapter seat 51 drives the swing arm 31 to descend, so that the swing arm 31 drives the clamping jaw 41 and the reagent bottle to descend. The clamping jaw 41 drives the reagent bottle to pass through the loading and unloading port 12 and approach the reagent tray 200, so that the reagent bottle extends into the reagent tray 200 and abuts against the reagent tray 200. When the reagent bottle touches the bottom of the reagent tray 200, the swing arm 31 moves downward relative to the mounting base 43, so that the swing arm 31 and the installation boss 431 cooperate to squeeze the buffer elastic member 44, thereby preventing the reagent tray 200 from being damaged due to excessive insertion force of the reagent bottle, ensuring that the reagent bottle is inserted in place, and the structure is stable and reliable. It can be understood that after the reagent tray 200 is placed in place, the buffer elastic member 44 pushes the swing arm 31 upward under the action of the elastic restoring force, so that the swing arm 31 is reset, which has the advantages of flexible and reliable structure.

[0051] In this embodiment, the moving driving assembly 23 includes a moving driving member 231, a second driving pulley 232, a second driven pulley 233 and a second synchronous belt 234. The second driving pulley 232 and the second driven pulley 233 are respectively arranged at both ends of the base 21. The second synchronous belt 234 is wound between the second driving pulley 232 and the second driven pulley 233. The second synchronous belt 234 is connected to the tray 22. The moving driving member 231 can drive the second driving pulley 232 to rotate, so as to drive the tray 22 to slide along the extending direction of the base 21 through the second driven pulley 233 and the second synchronous belt 234. Moreover, the transportation mechanism 20 further includes a second guide rail 25 and a second slider 26. The second guide rail 25 is arranged on the base 21 and is consistent with the extending direction of the base 21. The second slider 26 is connected to the lower side of the tray 22 and is in sliding contact and cooperation with the second guide rail 25.

[0052] As Figure 1 and Figure 5As shown, the moving drive member 231 is disposed at one end of the base 21. The second driving wheel 232 is connected to the moving drive member 231. The second driven wheel 233 is disposed at the other end of the base 21. The second synchronous belt 234 is wound between the second driving wheel 232 and the second driven wheel 233 and is connected to the tray 22. When the moving drive member 231 drives the second driving wheel 232 to rotate, the second driving wheel 232 drives the second synchronous belt 234 to rotate through the second driven wheel 233, so that the second synchronous belt 234 drives the tray 22 to move along the extending direction of the base 21, realizing the linear transportation of the reagent bottles. It not only occupies a small space, but also is convenient for manual picking and placing of the reagent bottles from one side of the tray 22. The structure is flexible and reliable. And when the tray 22 moves along the base 21, the tray 22 drives the second slider 26 to slide along the second guide rail 25. The sliding fit between the second slider 26 and the second guide rail 25 plays a role in guiding the sliding of the tray 22, improving the smoothness of the movement of the tray 22.

[0053] In this embodiment, a placement cavity 221 is formed in the tray 22. A placement opening 222 communicating with the placement cavity 221 is formed on one side of the tray 22. The buffer rack 24 can be placed into the placement cavity 221 from the placement opening 222. And a plurality of buffer slots 241 arranged at intervals are formed on the buffer rack 24. The buffer slots 241 are used for holding the reagent bottles. As Figure 1 and Figure 5 shown, there are a plurality of buffer slots 241 on the buffer rack 24. One reagent bottle can be placed in each buffer slot 241. By pushing the buffer rack 24 into the placement cavity 221 from the placement opening 222, the tray 22 can drive the buffer rack 24 and the reagent bottles to reciprocally move along the base 21 in a direction close to or away from the vertical plate 11, thereby realizing the batch loading and unloading of the reagent bottles and further improving the loading and unloading efficiency.

[0054] Furthermore, a second baffle 223 is disposed on the lower side of the tray 22. The number of the second baffles 223 is the same as and corresponds to the number of the buffer slots 241 one by one. A second optocoupler 211 corresponding to an external barcode scanner is disposed on the base 21. A second induction slot for the second baffle 223 to extend into is formed on the second optocoupler 211. As Figure 1 and Figure 5As shown in the figure, a buffer rack 24 is placed inside the tray 22. The buffer rack 24 has a plurality of buffer slots 241, and a reagent bottle can be placed in each buffer slot 241. When the buffer rack 24 is placed in place, a second baffle 223 is provided at the lower side of the tray 22 corresponding to the position of each buffer slot 241. A second optocoupler 211 is provided on the base 21, and a barcode scanner is provided on one side of the base 21 corresponding to the position of the second optocoupler 211. The tray 22 drives the buffer rack 24 and a plurality of second baffles 223 to move. When any one of the second baffles 223 moves into the second induction slot of the second optocoupler 211, the reagent bottle corresponding to the second baffle 223 moves to the position corresponding to the barcode scanner, and the barcode scanner can scan the barcode on the reagent bottle, improving the convenience of barcode scanning.

[0055] In this embodiment, the number of loading and unloading ports 12 is four. The rotation driving assembly 32 can drive the swing arm 31 to drive the clamping jaw 41 to move along a circular movement track, and the four loading and unloading ports 12 are spaced apart on the movement track.
