[0040] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0041] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0042] like Figures 1 to 4 As shown, this embodiment provides a conveying device with a mixing function, which comprises a base 100, a transfer rack 200, a vibration assembly 300 and a carrier 400, wherein the transfer rack 200 is arranged on the base 100, and can be transferred between a material receiving position and a material feeding position; the vibration assembly 300 is arranged on the transfer rack 200; the carrier 400 is arranged at the output end of the vibration assembly 300, the carrier 400 is used to hold a reaction cup, and the vibration assembly 300 is used to vibrate the carrier 400 and mix the sample and reagent in the reaction cup.

[0043] The above arrangement allows the transfer and vibration of the reaction cup to be performed synchronously, so that the reaction cup and transportation time and the mixing time of the sample and reagent in the reaction cup at least partially overlap, which reduces the overall test time to a certain extent and improves the test efficiency.

[0044] Regarding the structure of the vibration assembly 300, in some embodiments, the vibration assembly 300 includes a vibration driving member 310 and an eccentric shaft 320, wherein the vibration driving member 310 is disposed on the transfer frame 200; the eccentric shaft 320 is rotatably disposed on the transfer frame 200, and one end is transmission-connected to the vibration driving member 310; the supporting member 400 is disposed at the other end of the eccentric shaft 320, and is slidably disposed on the transfer frame 200.

[0045] The above arrangement can move the carrier 400 through the rotation of the eccentric shaft 320, and combined with the sliding arrangement of the carrier 400, the carrier 400 is caused to shake, thereby causing the reaction cup on the carrier 400 to shake, thereby mixing the sample and reagent inside.

[0046] It is worth noting that the carrier 400 has a receiving groove 410, and the receiving groove 410 is used to place a reaction cup.

[0047] Regarding the sliding arrangement of the bearing member 400, in some embodiments, specifically, the transfer frame 200 is provided with a guide portion 210, and the vibration assembly 300 further includes a bearing seat 330, the bearing seat 330 is provided with a bearing hole, the other end of the eccentric shaft 320 is rotatably arranged in the bearing hole, and can rotate in the bearing hole, and the bearing seat 330 slides relative to the guide portion 210. The above arrangement simplifies the structure of the bearing member 400 and the bearing seat 330, and is convenient for separate production; at the same time, since the bearing seat 330 and the transfer frame 200 are in sliding cooperation, it is convenient to replace them separately after wear, thereby reducing maintenance costs.

[0048] In some embodiments, at least two carriers 400 are disposed on the same carrier seat 330 to carry at least two reaction cups. The above configuration can simultaneously complete the transfer and shaking of at least two reaction cups to complete the mixing of the internal samples and reagents, thereby improving the efficiency of transfer and mixing.

[0049] The eccentric shaft 320 includes a first shaft 321, a second shaft 322 and a connecting portion 323. The first shaft 321 and the second shaft 322 are located at both ends of the connecting portion 323, and the axes of the first shaft 321 and the second shaft 322 are staggered. The first shaft 321 is connected to the vibration driving member 310 in a transmission manner, and the second shaft 322 is connected to the bearing seat 330. The above-mentioned structure is conducive to the processing of the eccentric shaft 320 and reduces the processing cost; at the same time, the shaft parts are easy to cooperate with other components, reducing the difficulty of assembly and improving the assembly efficiency.

[0050] In some embodiments, the vibration assembly 300 includes two limiting shafts 340, which are fixedly connected to the bearing seat 330 and form a limiting channel, and the guide part 210 is slidably arranged in the limiting channel. The above arrangement realizes the limitation of the sliding track of the bearing seat 330. Under the driving of the eccentric shaft 320 and the limiting effect of the limiting shaft 340, the bearing seat 330 presents an elliptical shaking track, thereby improving the centrifugal strength of the sample and the test inside the reaction cup during the rotation process.

[0051] Of course, in other embodiments, the centrifugal strength generated during the mixing process can be changed by changing the output speed of the vibration driving member 310. The vibration driving member 310 can be a servo motor.

[0052] To reduce wear, in some embodiments, the vibration assembly 300 includes a first bearing 341, and two first bearings 341 are provided. The two first bearings 341 are respectively sleeved on the corresponding limit shafts 340, and the guide portion 210 is slidably disposed between the two first bearings 341. The provision of the first bearings 341 enables rolling friction between the limit shaft 340 and the guide portion 210, thereby reducing the friction coefficient, thereby reducing wear and increasing the service life.

[0053] In addition, the vibration assembly 300 further includes a second bearing 326, the inner ring of the second bearing 326 is fixed to the other end of the eccentric shaft 320, and the outer ring of the second bearing 326 is fixed to the bearing seat 330. The provision of the second bearing 326 can also avoid sliding friction between the eccentric shaft 320 and the bearing seat 330, thereby improving the durability of the eccentric shaft 320 and the bearing seat 330. Among them, the inner ring of the second bearing 326 is fixed to the second shaft 322.

[0054] Furthermore, two second bearings 326 are provided, and a bearing groove 331 connected to the bearing hole is provided at each end of the bearing hole of the bearing seat 330. The two second bearings 326 are respectively provided in the corresponding bearing grooves 331, and are both sleeved on the eccentric shaft 320. Among them, the diameter of the bearing groove 331 is larger than the diameter of the bearing hole. The provision of the two second bearings 326, on the one hand, can improve the force balance between the eccentric shaft 320 and the bearing seat 330, and further improve the durability of the two; on the other hand, the position of the bearing seat 330 can be limited by the limitation of the two second bearings 326 and the bearing groove 331, so as to avoid the bearing seat 330 from being separated from the eccentric shaft 320 along the axis of the eccentric shaft 320, thereby improving the safety of use.

[0055] It is worth noting that, in order to ensure the stability of the connection, the inner ring of the second bearing 326 is interference fit with the eccentric shaft 320 .

[0056] Furthermore, the vibration assembly 300 also includes a clamping screw 350, and the other end of the eccentric shaft 320 is provided with a fixing screw hole 324, the clamping screw 350 is screwed into the fixing screw hole 324, and the nut of the clamping screw 350 is crimped onto the inner ring of the second bearing 326 above. Among them, the two second bearings 326 are arranged at intervals in the vertical direction, one on the top and the other on the bottom. The clamping screw 350 further improves the connection strength between the second bearing 326 and the eccentric shaft 320, and can effectively prevent the eccentric shaft 320 and the second bearing 326 from being separated, thereby improving the safety of use. A stopper 325 is protruded outwardly at one end of the second shaft 322 close to the connecting portion 323, and the stopper 325 abuts against the inner ring of the second bearing 326 below. By means of the stopper 325 and the clamping screw 350, the two second bearings 326 are fixed to the second shaft 322 in the axial direction of the second shaft 322; combined with the two bearing grooves 331, the second shaft 322 and the bearing seat 330 are limited in the axial direction of the second shaft 322. The end of the outer ring of the second bearing 326 abuts against the bottom of the bearing groove 331.

[0057] In some embodiments, the vibration assembly 300 further includes a sensing member 361 and a triggering member 362. The sensing member 361 is disposed on the transport rack 200, and the triggering member 362 is disposed on the eccentric shaft 320. The rotation of the eccentric shaft 320 drives the triggering member 362 to trigger the sensing member 361. Specifically, when the eccentric shaft 320 rotates and drives the carrier 400 to move to a preset position, the triggering member 362 triggers the sensing member 361, and the eccentric shaft 320 stops rotating. The setting of the sensing member 361 enables the position of the eccentric shaft 320 when it stops to be determined, thereby ensuring that the reaction cup is accurately received and the reaction cup can be delivered to the specified position.

[0058] To facilitate processing and production, the vibration assembly 300 further includes a rotating flange 370, which is fixed to the transport frame 200, and the eccentric shaft 320 is rotatably arranged on the rotating flange 370. The rotating flange 370 is provided with a bearing seat, and a flange bearing 371 is provided between the eccentric shaft 320 and the bearing seat of the rotating flange 370. Specifically, the flange bearing 371 is provided between the rotating flange 370 and the first rod shaft 321. Two flange bearings 371 are provided, and the two flange bearings 371 are arranged at intervals on the rotating flange 370 along the vertical direction.

[0059] Regarding the transmission mode of power, in some embodiments, the vibration assembly 300 further includes a first driving wheel 381, a first driven wheel 382 and a first transmission member 383, wherein the first driving wheel 381 is arranged at the output end of the vibration driving member 310, the first driven wheel 382 is arranged at one end of the eccentric shaft 320, and the first transmission member 383 is arranged between the first driving wheel 381 and the first driven wheel 382. Among them, the diameter of the first driving wheel 381 is greater than the diameter of the first driven wheel 382, ​​so as to achieve acceleration to increase the centrifugal strength of the mixing process. Among them, the transmission ratio between the first driving wheel 381 and the first driven wheel 382 can be changed to increase or reduce the centrifugal strength of the mixing. In this embodiment, the first driving wheel 381 and the first driven wheel 382 are both synchronous pulleys. In other embodiments, the vibration driving member 310 and the eccentric shaft 320 can also be meshed with gears to transmit power, but it is not limited thereto.

[0060] In order to improve the degree of automation of transportation, in some embodiments, the conveying device with a mixing function also includes a transfer drive 510, which is arranged on the base 100, and the output end of the transfer drive 510 is connected to the transfer frame 200 by transmission. Among them, the transfer drive 510 can be a servo motor. The output end of the transfer drive 510 is provided with a second driving wheel 520, the base 100 is rotatably provided with a second driven wheel 530, the second transmission member 540 is wound between the second driving wheel 520 and the second driven wheel 530, and the transfer frame 200 is fixed to the second transmission member 540 through a connecting member 550. Specifically, one end of the connecting member 550 is screwed to the transfer frame 200; the other end is clamped on the outside of the second transmission member 540. Among them, the second driving wheel 520 and the second driven wheel 530 are both synchronous pulleys, and the second transmission member 540 is a synchronous belt.

[0061] This embodiment also provides a sample analyzer, including a conveying device with a mixing function. The mixing function is integrated in the conveying device, and there is no need to arrange a mixing device separately, so that the sample analyzer has a reduced footprint, and the sample and reagent are mixed while being transported, thereby shortening the test time and improving the test efficiency.

[0062] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention.
