[0001] The present invention relates to the technical field of sample analysis, and in particular to an automatic loading device for a reaction cup and a sample analyzer. Background Art

[0002] In clinical testing equipment, such as chemiluminescence analyzers and coagulation analyzers, an automatic cup adding mechanism is required to automatically add reaction cups to the test process, thereby reducing manual operations and improving the automation of the instrument. Existing automatic cup adding mechanisms usually use an inclined chute to transport the reaction cup. Since the cup edge size of the reaction cup is larger than the width size of the chute, the reaction cup can be hung in the chute for transportation. However, when output to the exit, the reaction cups that are in the wrong state, such as horizontal or bottom-up, are also squeezed toward the exit, resulting in a stuck situation at the exit of the reaction cup compartment.

Specific embodiments

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0029] It should be noted that all the directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the attached drawings). If the specific posture changes, the directional indications will also change accordingly.

[0030] In addition, the descriptions involving "first", "second", etc. in the present invention are only for descriptive purposes, and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of the said features. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement them. When the combination of technical solutions appears to be contradictory or unable to be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0031] An embodiment of the present invention provides a sample analyzer that can detect and analyze samples (such as blood, urine, etc.) to provide reliable digital basis for clinical diagnosis of various diseases of patients. During the detection process, the sample analyzer needs to use a reaction cup as a sample container to accommodate the sample and analyze and detect the sample.

[0032] See also Figure 1 and Figure 2 The sample analyzer of this embodiment includes an analysis device, a gripper device and an automatic loading device. The gripper device is used to transfer the reaction cup 10 loaded by the automatic loading device to the analysis device. The automatic loading device of this embodiment includes a hopper 100, a conveying mechanism 200, a cup-pushing mechanism 300 and a conveying frame 400. The hopper 100 is used to store the cuvette 10. The conveying mechanism 200 is used to grab and convey the cuvette 10 in the hopper 100. The cup-pushing mechanism 300 is provided with a guide channel 310 and a cup-pushing structure 320 formed at the entrance of the guide channel 310. When the conveying mechanism 200 conveys the cuvette 10 to the entrance of the guide channel 310, the cup-pushing structure 320 can pry the cuvette 10 to guide the head or tail of the cuvette 10 into the guide channel 310. The guide channel 310 is used to convey the cuvette 10 along its length direction. The conveying frame 400 is provided with a slide groove 410. The exit of the guide channel 310 is butted against the upper end of the slide groove 410. The top wall of the slide groove 410 is used to abut against the cup edge of the cuvette 10 so as to hang the cuvette 10 on the conveying frame 400. The reaction cup 10 may be an optical cup with a circular radial cross section, so as to facilitate passing through the guide channel 310. Of course, the reaction cup 10 may also be a reaction container with a square radial cross section.

[0033] It should be noted that the length of the reaction cup 10 in this embodiment refers to the length from the head to the tail of the reaction cup 10, that is, the height of the reaction cup when it is standing upright with the mouth of the reaction cup facing upward.

[0034] It is understandable that when the conveying mechanism 200 conveys the reaction cup 10 to the entrance of the guide channel 310, the cup-pushing structure 320 can pull the reaction cup 10 to guide the head or tail of the reaction cup 10 into the guide channel 310. The guide channel 310 can convey the reaction cup 10 along its length direction, so that the reaction cup 10 has only one posture in the guide channel 310, that is, the horizontally arranged posture. The exit of the guide channel 310 is docked with the upper end of the chute 410, so that the reaction cup 10 adopts one posture to enter the chute 410. Due to the effect of gravity, the reaction cup 10 is turned on the chute 410 to a state with the cup mouth facing up, so that the reaction cup 10 is hung on the conveying rack 400, and the reaction cup 10 will not be stuck during the transmission process. The setting of the automatic loading device can reduce the manual cup adding operation of the sample analyzer and improve the automation of the instrument.

[0035] In one embodiment, please refer to Figure 1 , the automatic loading device further includes a frame 600, and the hopper 100, the conveying mechanism 200, the cup-pushing mechanism 300, and the conveying rack 400 are all installed on the frame 600.

[0036] In one embodiment, please refer to Figure 1 , the guiding channel 310 extends along a first direction, the sliding groove 410 extends along a second direction, and both the first direction and the second direction are arranged at an angle with the horizontal plane, so that the reaction cup 10 can be conveyed from the inlet of the guiding channel 310 to the outlet under the action of gravity, and the reaction cup 10 can also slide from the upper end of the sliding groove 410 to the lower end of the sliding groove 410 under the action of gravity, thereby realizing the conveyance of the reaction cup 10.

[0037] In this embodiment, the first direction and the second direction are arranged at an angle of 0 - 15 degrees, so that the reaction cup 10 can smoothly slide from the guiding channel 310 to the sliding groove 410. Further, the angle between the first direction and the second direction can be selected as 0 degree, 3 degrees, 6 degrees, 9 degrees, 12 degrees or 15 degrees. When the angle between the first direction and the second direction is 0 degree, the first direction is parallel to the second direction. Of course, the first direction can also coincide with the second direction.

[0038] Of course, in other embodiments, the angle between the first direction and the second direction can also be greater than 15 degrees. For example, the angle between the first direction and the second direction can also be 18 degrees or 20 degrees, but the angle between the first direction and the second direction cannot be too large, so as to avoid affecting the smoothness of the reaction cup 10 sliding from the guiding channel 310 to the sliding groove 410.

[0039] In one embodiment, please refer to Figures 1 to 4 , the conveying mechanism 200 includes a rotating disk 210 and a driving assembly 220. The rotating disk 210 is installed in the hopper 100 and is rotatably connected to the hopper 100. A plurality of cup-carrying grooves 201 are arranged at intervals along the circumferential edge of the rotating disk 210, and each cup-carrying groove 201 is used to grasp one reaction cup 10. The driving assembly 220 is in transmission connection with the rotating disk 210 and is used to drive the rotating disk 210 to rotate. The rotation of the rotating disk 210 can drive each reaction cup 10 in each cup-carrying groove 201 to move in an arc, so as to continuously push the reaction cup 10 into the guiding channel 310. As the rotating disk 210 continues to rotate, the next reaction cup 10 pushed into the guiding channel 310 by the cup-pushing structure 320 will push the previous reaction cup 10 towards the sliding groove 410 until the reaction cup 10 falls onto the sliding groove 410. For the reaction cup 10 that has fallen onto the sliding groove 410, under the action of gravity, the rim of the reaction cup 10 is hung on the top wall of the sliding groove 410, and the body of the reaction cup 10 drops down, so as to form a state where the mouth of the reaction cup 10 faces upwards.

[0040] It can be understood that in the prior art, a grooved plate is usually used to move up and down reciprocally to convey the reaction cup 10. When the top plate of the groove is lifted, the reaction cup 10 falls into the groove, which is an effective action. However, the downward movement has no direct effect on adding the cup, and this step wastes time.

[0041] The rotating disk 210 of this embodiment can rotate continuously in the clockwise or counterclockwise direction, so that the rotation of the rotating disk 210 can drive the reaction cups 10 in each cup conveying groove 201 to move in an arc. During the arc movement of each cup conveying groove 201, the reaction cups 10 can be grabbed continuously and conveyed to the inlet of the guiding channel 310. Therefore, during the rotation of the rotating disk 210, each cup conveying groove 201 moves to the inlet of the guiding channel 310 continuously in sequence, so that the inlet of the guiding channel 310 will not be idle, and the time utilization rate of the cup adding process of the reaction cup 10 is high, resulting in a relatively high cup adding efficiency of the reaction cup 10, and thus it can meet the scenarios of high-speed cup adding and cup supplying of the automatic loading device.

[0042] In this embodiment, the size of each cup conveying groove 201 is slightly larger than the size of a reaction cup 10. Thus, on the condition of ensuring sufficient accommodation clearance between the reaction cup 10 and the cup conveying groove 201, only one reaction cup 10 can be conveyed by one cup conveying groove 201, ensuring that only one reaction cup 10 corresponds to the inlet of the guiding channel 310 at the same time, and further ensuring the stability and reliability of the reaction cup 10 being pushed into the guiding channel 310 by the cup pushing structure 320.

[0043] Specifically, the driving assembly 220 includes a driving motor 221, a driving belt pulley 222, a driven belt pulley 223 and a belt 224. The rotating shaft of the driven belt pulley 223 penetrates through the hopper 100 and is connected to the rotating disk 210. The driving motor 221 is installed on the hopper 100 and is connected to the driving belt pulley 222. The belt 224 is wound between the driving belt pulley 222 and the driven belt pulley 223. When the driving motor 221 works, it can drive the driving belt pulley 222 to rotate. The rotation of the driving belt pulley 222 can drive the belt 224 to move. The movement of the belt 224 can drive the driven belt pulley 223 to rotate, and the rotating disk 210 can rotate counterclockwise following the driven belt pulley 223.

[0044] In one embodiment, please refer to Figure 1 and Figure 4 , the plane where the rotating disk 210 is located is arranged at an angle relative to the vertical direction. The rotating disk 210 includes a first side surface 211 and a second side surface 212 which are oppositely arranged. The first side surface 211 faces upward, and each cup conveying groove 201 is opened on the first side surface 211, so as to prevent the reaction cups 10 in each cup conveying groove 201 from falling during the arc movement. When the cup conveying groove 201 on the rotating disk 210 rotates to the lower end, the reaction cups 10 in the hopper 100 randomly enter the cup conveying groove 201.

[0045] In this embodiment, please refer to Figures 1 to 7 , the hopper 100 is provided with a bin 110, a bin opening 120 and a feeding port 130 communicated with the bin 110. The reaction cup 10 can be poured into the bin 110 through the bin opening 120 for storage, and the feeding port 130 is opened on the upper side of the hopper 100. The cup conveying groove 201 is provided with a first opening 202 formed on the first side surface 211 and a second opening 203 formed on the outer wall of the circumferential surface of the rotating disk 210. The inner wall of the bin 110 is disposed opposite to the second opening 203 to limit the reaction cup 10 in the cup conveying groove 201, so that during the rotation of the rotating disk 210, the reaction cup 10 can be stably accommodated in the cup conveying groove 201 and is not likely to fall out of the cup conveying groove 201. Further, a cup dialing mechanism 300 is disposed at the feeding port 130, and the cup dialing structure 320 is used to dial the reaction cup 10 to guide the head or tail of the reaction cup 10 out of the cup conveying groove 201 through the second opening 203, so as to guide the head or tail of the reaction cup 10 into the guiding channel 310. Further, during the rotation of the rotating disk 210, the reaction cup 10 can fall downward after passing the highest point. The cup dialing structure 320 is located below the reaction cup 10. After the reaction cup 10 abuts against the cup dialing structure 320, the cup dialing structure 320 can dial the reaction cup 10 to leave the cup conveying groove 201. Specifically, the bottom wall of the bin 110 is arranged at an angle with the horizontal plane, so that the reaction cup 10 can be stably stored in the bin 110.

[0046] In this embodiment, the groove depth of the cup conveying groove 201 is smaller than the radial dimension of the reaction cup 10. The cup dialing structure 320 is used to dial the reaction cup 10 protruding from the notch of the cup conveying groove 201 to guide the head or tail of the reaction cup 10 into the guiding channel 310, so as to facilitate the dialing action of the cup dialing structure 320 on the reaction cup 10. Specifically, the length direction of the cup conveying groove 201 is perpendicular to the radial direction of the rotating disk 210, so as to facilitate guiding the head or tail of the reaction cup 10 into the guiding channel 310.

[0047] It can be understood that the cup conveying groove 201 has a first groove depth extending along the axial direction of the rotating disk 210 and corresponding to the first opening 202, and a second groove depth extending along the radial direction of the rotating disk 210 and corresponding to the second opening 203. Therefore, the fact that the groove depth of the cup conveying groove 201 in this embodiment is smaller than the radial dimension of the reaction cup 10 specifically means that the first groove depth and / or the second groove depth of the cup conveying groove 201 is smaller than the radial dimension of the reaction cup 10.

[0048] Of course, in other embodiments, the cup transfer groove may also be formed on the outer circumferential wall of the rotating disk 210. The cup transfer groove can also grasp the reaction cup 10 and transfer the reaction cup 10 to the inlet of the guiding channel 310. However, the notch of the cup transfer groove is only formed on the outer circumferential wall of the rotating disk 210, which is not convenient for the reaction cup 10 to be grasped into the cup transfer groove through the notch of the cup transfer groove, thus affecting the cup grasping efficiency of the cup transfer groove.

[0049] In one embodiment, please refer to Figure 1 and Figure 8 , the automatic loading device further includes a transfer mechanism 500. The transfer mechanism 500 is disposed in butt joint with the lower end of the chute 410 and is used to transfer the reaction cup 10 at the lower end of the chute 410 to a preset position, thereby realizing the transfer of the reaction cup 10.

[0050] Specifically, the transfer mechanism 500 includes a fixed seat 510, a transfer disk 520, and a transfer motor 530. The fixed seat 510 is installed at the lower end of the conveying frame 400. The transfer disk 520 is rotatably connected to the fixed seat 510. A plurality of transfer grooves 521 are spaced apart on the outer peripheral wall of the transfer disk 520. The transfer motor 530 is in transmission connection with the transfer disk 520 and is used to drive the transfer disk 520 to rotate, so that one of the transfer grooves 521 in the transfer disk 520 can be opposite to the lower end of the chute 410 to receive the reaction cup 10, and after the transfer disk 520 rotates, the reaction cup 10 is transferred to the preset position. A top plate for ejecting the reaction cup 10 from the transfer groove 521 at the preset position is formed in the fixed seat 510, so as to facilitate the gripper device to grasp the reaction cup 10 and transfer the reaction cup 10 to the analysis device for testing and analysis.

[0051] Furthermore, the transfer mechanism 500 further includes a detector 540. The detector 540 is installed above the top plate and is used to sense the reaction cup 10 at the preset position. When it is detected that the reaction cup 10 at the preset position has been taken out, the transfer motor 530 can drive the transfer disk 520 to rotate one station to transfer the next reaction cup 10 to the preset position for the gripper device to grasp next time.

[0052] Please refer to Figures 1 to 8When the automatic loading device of the present embodiment is working, during the rotation of the rotating disk 210, the cup transporting groove 201 can grab the reaction cup 10 and transfer it to the entrance of the guide channel 310 of the cup-pushing mechanism 300. The cup-pushing structure 320 of the cup-pushing mechanism 300 can pry the reaction cup 10 to guide the head or tail of the reaction cup 10 into the guide channel 310. The guide channel 310 can transport the reaction cup 10 along its length direction, so that the reaction cup 10 has only one posture in the guide channel 310, that is, the horizontally arranged posture. The exit of the guide channel 310 is connected to the upper end of the slide groove 410, so that The reaction cup 10 enters the slide 410 in a certain posture. Due to the effect of gravity, the reaction cup 10 flips on the slide 410 to a state with the cup mouth facing upward, so that the reaction cup 10 is hung on the conveying rack 400 for conveying. The reaction cup 10 at the lower end of the slide 410 can be grasped by the transfer groove 521 of the transfer mechanism 500 and transferred to a preset position. At the preset position, the reaction cup 10 is ejected by the top plate in the fixed seat 510, which is convenient for the gripper device to grasp the reaction cup 10, thereby realizing high-efficiency and high-speed automatic cup adding and cup supply of the automatic loading device with low failure rate, thereby being able to support a higher instrument detection speed of the sample analyzer.

[0053] The above disclosure is only the preferred embodiment of the present invention, which certainly cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope of the present invention.
