Of course, in order to drive the sample rack 1 to transfer between two adjacent sample analyzers 10 through the cascade channel 23, the present embodiment is provided with a bridge assembly 24 between the two adjacent sample analyzers for driving the sample rack 1 from the unloading zone 14 of one of the sample analyzers 10 into the loading zone 13 of the other sample analyzer 10.
As shown in fig. 3, the bridge assembly 24 of the present embodiment includes a support 241, a guide rail 242 parallel to the table 12 is provided on the support 241, a moving plate 243 slidably engaged with the guide rail 242 is mounted on the guide rail 242, and a cascade driving mechanism for driving the moving plate 243 to move along the guide rail 242 is provided on the support 241. Specifically, the cascade drive mechanism may be implemented in various existing manners, such as a ball screw mechanism, a rack and pinion mechanism, and the like. The cascade driving mechanism of the embodiment comprises two synchronous pulleys 244 respectively positioned at two ends of the guide rail 242, a synchronous belt 245 is arranged between the two synchronous pulleys 244, the synchronous belt 245 is fixedly connected with a moving plate 243, and a cascade driving motor 246 in transmission connection with one of the synchronous pulleys 244 is arranged on the bracket 241. In a preferred implementation of this embodiment, the support 241 is provided with an optocoupler sensor 247 for detecting the position of the moving plate 243, and the moving plate 243 is provided with a light blocking sheet 248 cooperating with the optocoupler sensor 247.
The moving plate 243 of the present embodiment is provided with a limiting mechanism, and the limiting mechanism is used to be in limiting cooperation with the sample rack 1 to drive the sample rack 1 to move from the unloading area 14 of one of the adjacent sample analyzers 10 toward the loading area 13 of the other sample analyzer 10 through the cascade channel 23.
Specifically, as shown in fig. 4-6, the moving plate 243 of the present embodiment is located below the workbench 12, the workbench 12 and/or the cascade channel 23 are provided with a table top notch 25, and the limiting mechanism passes through the table top notch 25 to be in limiting fit with the bottom groove 2 of the sample rack 1. Specifically, the moving plate 243 of the present embodiment is located below the unloading area 14 of one of the sample analyzers 10 at the initial position. The spacing mechanism interval is set to be at least one, and the spacing mechanism interval of this embodiment is set to be 2, wherein one spacing mechanism is located below the unloading area 14 of one sample analyzer 10, and the other spacing mechanism is disposed corresponding to the cascade channel 23. That is, in the present embodiment, the stage surface notch 25 is provided on the stage 12 located at the unloading area 14 of one of the sample analyzers 10, while the stage surface notch 25 is correspondingly provided on the cascade channel 23 of the adjacent two sample analyzers 10. The spacing means capable of extending upwardly through the mesa slot 25 into spacing engagement with the bottom recess 2 of the sample holder 1 may be implemented in a number of ways. As shown in fig. 3, the limiting mechanism of the present embodiment includes a pawl 26, a fixed shaft 27 is disposed on a moving plate 243, the fixed shaft 27 is parallel to the table 12 and perpendicular to a guiding rail 242, the pawl 26 is mounted on the fixed shaft 27 in a rotating fit, and the center of gravity of the pawl 26 is located on a side of the fixed shaft 27 facing the lower end of the pawl 26. Thus, when finger 26 is positioned below table 12, finger 26 is in an inclined state at this time due to the force applied to finger 26 by table 12, as shown in fig. 4. When the pusher dog 26 moves to the position of the table top notch 25, the acting force exerted by the workbench 12 on the pusher dog 26 disappears, the pusher dog 26 rotates around the fixed shaft 27 under the action of gravity to reach the vertical position, and the upper end of the pusher dog 26 extends upwards to the position above the table top notch 25 to be in limit fit with the bottom groove 2 of the sample rack 1, as shown in fig. 5. The moving plate 243 moves the finger 26 along the guide rail 242, and the finger 26 moves the sample rack 1 toward the loading area 13 of the other sample analyzer 10, as shown in fig. 6. The sample rack 1 is provided with sample placing positions for placing sample tubes, and the shifting claw 26 drives the sample rack 1 to move towards the loading area 13 of the other sample analyzer 10 each time by a distance which is equal to an integral multiple of the distance between two adjacent sample placing positions. Specifically, the finger 26 of the present embodiment drives the sample rack 1 toward the loading area 13 of the other sample analyzer 10 each time by a distance equal to the interval between the adjacent two sample placement positions. After the finger 26 drives the sample rack 1 to move towards the other sample analyzer 10 by a set distance, the moving plate 243 is reset, and during the resetting, when the finger 26 contacts the workbench 12, the finger 26 rotates under the action of the force applied by the workbench 12 to the finger 26 until the finger 26 is positioned below the workbench 12, so that no interference is caused to the movement of the sample rack 1 in the unloading area 14. In the preferred implementation of this embodiment, the top surface of the finger 26 is provided with a slope 261, and when the finger 26 is located in the vertical direction, the slope makes the height of the finger 26 facing the side of the other sample analyzer 10 higher, so that interference between the finger 26 and the side wall of the bottom groove 2 of the sample rack 1 during rotation of the finger 26 extending out of the mesa slot 25 can be avoided. In order to prevent the finger 26 from continuing to rotate under the interaction force with the sample rack 1, which results in the problem of achieving a limit fit structure, the present embodiment is provided with a limit shaft 28 for limiting the rotation range of the finger 26 on the moving plate 243. The limiting shaft 28 of this embodiment is located on the side of the lower end of the finger 26 facing the other sample analyzer 10. Of course, in other embodiments, the limiting shaft 28 may be disposed on a side of the upper end of the finger 26 facing away from the other sample analyzer 10.
Of course, in other embodiments, the limiting mechanism may be implemented in other manners, for example, the limiting mechanism may be a lever including a lever driving assembly for driving the lever to move toward a direction perpendicular to the table 12 for limiting engagement with the bottom recess 2 of the sample holder 1, and the moving plate 243 is provided with a lever driving assembly. When the moving plate 243 drives the shift lever to move to the position corresponding to the table notch 25, the shift lever driving assembly drives the shift lever to extend upwards to be in limit fit with the bottom groove 2 of the sample rack 1. When the sample rack 1 moves a set distance, the driving assembly of the driving lever drives the driving lever to retract downwards, and the moving plate 243 is reset.
In other embodiments, the moving plate 243 may be disposed above the unloading area 14 of one of the sample analyzers 10, and the stop mechanism is used to engage with the end of the sample rack 1 facing away from the other sample analyzer 10. The limiting mechanism can adopt a limiting baffle plate in limiting fit with the end part of the sample rack 1, and the sample rack 1 can be driven to pass through the cascade channel 23 to transfer between the adjacent sample analyzers 10 by utilizing the limiting fit relation between the limiting baffle plate and the sample rack 1. Specifically, the limit baffle may be fixedly mounted on the moving plate, and reset after the previous sample rack 1 is transferred by a set distance, and then the unloading assembly 16 is utilized to transfer another sample rack 1 to the position corresponding to the limit baffle, and the moving plate 243 drives the sample rack 1 to move in the process of driving the limit baffle to move. Of course, a baffle driving assembly for driving the limit baffle to move toward the direction perpendicular to the workbench 12 may be disposed on the moving plate 243, which will not be described again.
