Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and more specifically, the present invention relates to a cup feeding structure. Background Art

[0002] As a conventional medical testing device, a coagulation analyzer is used for the evaluation of antithrombotic drugs, can perform tests on the anticoagulation system and fibrinolysis system, and can evaluate the levels of various coagulation factors and the study of inhibitors.

[0003] During the use of a coagulation analyzer, when there are insufficient reaction cups, it is necessary to stop the machine to add reaction cups, resulting in low work efficiency.

[0004] In addition, existing coagulation analyzers do not have an alarm function when there are insufficient reaction cups, seriously affecting the use of coagulation analyzers. Summary of the Invention

[0005] In view of the above problems, the present invention is proposed to provide a cup feeding structure that overcomes or at least partially solves the above problems.

[0006] The present invention provides a cup feeding structure, which is used inside a coagulation analyzer. The cup feeding structure includes: a frame, which is installed inside the coagulation analyzer; a magazine, which is installed on the frame and is used for storing reaction cups; a turnover assembly, which is installed on the frame and is located on one side of the magazine, and the turnover assembly is used for turning over and orienting the reaction cups in the magazine; a distribution disk, which is installed at one end of the frame and is used for distributing reaction cups; a first conveying assembly, which is inclinedly installed at the discharge port of the magazine and is used for conveying the reaction cups in the magazine to the turnover assembly; a slideway, which is arranged between the turnover assembly and the distribution disk and is used for guiding the reaction cups turned over and oriented by the turnover assembly to the distribution disk.

Among them, the mounting plate is connected to the frame, the turnover bin, the channel assembly and the link mechanism are all installed on the mounting plate. The inlet of the turnover bin is connected to the upper end of the first conveying assembly. The turnover bin is communicated with the slideway through the channel assembly. The channel assembly rotates driven by the link mechanism to drive the reaction cups entering the channel assembly to slide into the slideway.

[0008] In a preferred embodiment of the present application, the channel assembly includes a first pivot plate, a second pivot plate, and a first link. The first pivot plate and the second pivot plate are both pivotally connected to the mounting plate. The lower surface of the first pivot plate and the upper surface of the second pivot plate form a channel for the reaction cup to pass through. The first link is respectively rotatably connected to the first pivot plate and the second pivot plate so that a predetermined distance is always maintained between the lower surface of the first pivot plate and the upper surface of the second pivot plate.

[0009] In a preferred embodiment of the present application, the link mechanism includes a rotatable shaft, a second link, and a third link. The first end of the second link is fixedly connected to the shaft. The second end of the second link is hingedly connected to the first end of the third link.

[0012] In a preferred embodiment of the present application, the first transfer assembly includes a driving component and a conveyor belt with a plurality of transfer plates. The transfer plates are used to carry the reaction cups. The driving component is used to drive the conveyor belt to rotate so as to transfer the reaction cups to the turnover assembly.

[0013] In a preferred embodiment of the present application, the cup feeding structure further includes a second transfer assembly inclinedly installed at the bottom of the bin. The second transfer assembly is used to transfer the reaction cups located in the bin to the lower end of the first transfer assembly.

[0014] In a preferred embodiment of the present application, the first transfer assembly drives the second transfer assembly to rotate through a transmission belt.

[0089] It should be understood that the drawings are not drawn to scale and show various features presented in a slightly simplified manner to illustrate the basic principles of the present invention. In the drawings of the present invention, the same reference numerals represent the same or equivalent parts of the present invention. Detailed Embodiments

[0090] Hereinafter, various exemplary embodiments of the present invention will be described in more detail with reference to the drawings.

[0091] The following various exemplary embodiments of the present invention will be described more specifically with reference to the drawings.

[0092] See Figure 1 - Figure 2As shown in the figure, the present invention relates to a cup feeding structure which is used inside a coagulation analyzer. The cup feeding structure includes: a frame 1, a magazine 2, a turnover assembly 4, a distribution disc 6, a first conveying assembly 3, and a chute 5. Among them, the frame 1 is installed inside the coagulation analyzer; the magazine 2 is installed on the frame 1 and is used for storing reaction cups; the turnover assembly 4 is installed on the frame 1 and is located on one side of the magazine 2. The turnover assembly 4 is used for turning over and orienting the reaction cups in the magazine 2; the distribution disc 6 is installed at one end of the frame 1 and is used for distributing reaction cups; the first conveying assembly 3 is inclinedly installed at the discharge port of the magazine 2 and is used for conveying the reaction cups in the magazine 2 to the turnover assembly 4; the chute 5 is arranged between the turnover assembly 4 and the distribution disc 6 and is used for guiding the reaction cups turned over and oriented by the turnover assembly 4 to the distribution disc 6.

[0093] A large number of reaction cups can be stored in the magazine 2 (not shown in the figure). The magazine 2 is provided with four side walls and a bottom plate 202. The four side walls and the bottom plate 202 form a receiving space, and the reaction cups are installed in this receiving space. One of the side walls 203 is an inclined side wall, and a discharge port 204 is arranged on the inclined side wall 203. The first conveying assembly 3 is arranged at the discharge port 204 of this side wall 203 so as to convey the reaction cups in the magazine 2 to the turnover assembly 4; the turnover assembly 4 turns over the reaction cups and then orients them, and then conveys the oriented reaction cups to the distribution disc 6 through the chute 5 to supply reaction cups to the coagulation analyzer. When the sensor recognizes that there is a cup, the relevant robotic arm gripper of the coagulation analyzer will perform the cup picking operation. The frame 1 can play a role in supporting the above components. Figure 1 - Figure 2 The orientation mentioned here means ensuring that when the reaction cup slides into the chute 5, the cup mouth can face upward (that is, the cup bottom faces downward), so that it can be directly distributed and used after falling into the distribution disc.

[0094] Here, the orientation refers to ensuring that when the reaction cup slides into the chute 5, the cup mouth can face upward (i.e., the cup bottom faces downward), so that it can be directly distributed and used after falling into the distribution disc.

[0095] Furthermore, a lid (not shown in the figure) that can be opened can be provided at the top of the receiving space. By opening the lid, reaction cups can be put in.

[0096] Furthermore, as Figure 3 and Figure 4 shown, the first conveying assembly 3 includes a driving component 301 and a conveyor belt 303 with a plurality of conveying plates 302. The conveying plates 302 are used for carrying reaction cups, and the driving component 301 is used for driving the conveyor belt 303 to rotate so as to convey the reaction cups to the turnover assembly 4.

[0097] The driving component 301 can be selected as a motor. Here, the type of the driving component 301 is not limited to this. It can be any form in the prior art as long as it can achieve the above functions.

[0098] Exemplarily, the conveyor belt 303 is wound around the shaft 304 and the shaft 305, and the driving component 301 drives the shaft 304 to rotate, thereby driving the conveyor belt 303 to rotate.

[0099] Exemplarily, the first conveying assembly 3 further includes a mounting bracket 306, the mounting bracket 306 is mounted on the side wall of the silo 2, and the shafts 304 and 305 are mounted on the mounting bracket 306.

[0100] Further, the distance between two adjacent conveying plates 302 is greater than the diameter of the outer edge of the cup mouth of the reaction cup and less than twice the diameter of the outer edge of the cup mouth of the reaction cup, so as to ensure that only one reaction cup is carried between two adjacent conveying plates 302.

[0101] Exemplarily, the distance between two adjacent conveying plates 302 is greater than the diameter of the outer edge of the cup mouth of the reaction cup and less than 1.5 times the diameter of the outer edge of the cup mouth of the reaction cup.

[0102] Further, as Figure 5 , Figure 6 , Figure 8 and Figure 33 shown, the turnover assembly 4 includes a mounting plate 401, a turnover bin 402, a channel assembly 403 and a linkage mechanism 404. Among them, the mounting plate 401 is connected to the frame 1, the turnover bin 402, the channel assembly 403 and the linkage mechanism 404 are all mounted on the mounting plate 401, the inlet 4022 of the turnover bin 402 is connected to the upper end of the first conveying assembly 3, the turnover bin 402 is communicated with the slideway 5 through the channel assembly 403, and the channel assembly 403 rotates driven by the linkage mechanism 404 to drive the reaction cup entering the channel assembly 403 to slide into the slideway 5.

[0103] The reaction cup from the first conveying assembly 3 enters the turnover bin 402 through the inlet 4022 of the turnover bin 402, and then enters the channel assembly 403 through the outlet 4023 at the bottom of the turnover bin 402 (for reference, see Figure 33 ).

[0104] Next, the channel assembly 403 and the linkage mechanism 404 will be introduced in detail with reference to the accompanying drawings to illustrate how the linkage mechanism 404 drives the channel assembly 403 to tilt and drives the reaction cup entering the channel assembly 403 to slide through the channel 4034 into the slideway 5.

[0105] As Figure 6 , Figure 12 and Figure 13As shown, the channel assembly 403 includes a first pivot plate 4031, a second pivot plate 4032, and a first connecting rod 4033. Among them, both the first pivot plate 4031 and the second pivot plate 4032 are pivotally connected to the mounting plate 401. The lower surface of the first pivot plate 4031 and the upper surface of the second pivot plate 4032 form a channel 4034 for the reaction cup to pass through. The first end 40341 of the channel 4034 corresponds to the outlet 4023 of the turnover bin 402, and the second end 40342 of the channel 4034 corresponds to the inlet 502 of the slideway 5, so as to realize the connection between the turnover bin 402 and the slideway 5 and ensure that the reaction cup in the turnover bin 402 can enter the slideway 5. The first connecting rod 4033 is respectively rotatably connected to the first pivot plate 4031 and the second pivot plate 4032, so as to ensure that the first pivot plate 4031 and the second pivot plate 4032 rotate synchronously, so as to realize that a predetermined distance is always maintained between the lower surface of the first pivot plate 4031 and the upper surface of the second pivot plate 4032, and ensure that the channel 4034 will not affect the passage of the reaction cup during the rotation process.

[0106] The above embodiments introduce the transfer path of the reaction cup in the turnover assembly 4. Next, how to obtain the transfer power of the reaction cup in the channel 4034 will be introduced, that is, how the connecting rod mechanism 404 ensures that the reaction cup can be smoothly transferred in the direction of the slideway 5. The reaction cups in the turnover assembly 4 are placed disorderly, and a driving mechanism is needed to make the reaction cups inside move so that they can smoothly enter the channel 4034 and avoid accumulation in the turnover bin 402.

[0107] As Figure 13 shown, the connecting rod mechanism 404 includes a rotatable rotating shaft 4041, a second connecting rod 4042, and a third connecting rod 4043. The first end 40421 of the second connecting rod 4042 is fixedly connected to the rotating shaft 4041. The second end 40422 of the second connecting rod 4042 is hingedly connected to the first end 40431 of the third connecting rod 4043, and the second end 40432 of the third connecting rod 4043 is hingedly connected to the second pivot plate 4032.

[0108] Furthermore, the turnover assembly 4 further includes a driving component 405 for driving the rotating shaft 4041 to rotate around itself.

[0109] The driving component 405 can be selected as a motor. Here, the type of the driving component 405 is not limited to this, and it can be any form in the prior art as long as it can achieve the above functions.

[0110] As Figure 6 、 Figure 8 、 Figure 12 and Figure 13As shown in the figure, driven by the driving component 405, the rotating shaft 4041 rotates, driving the second connecting rod 4042 to rotate around the first end 40421 of the second connecting rod 4042. The second end 40422 of the second connecting rod 4042 drives the first end 40431 of the third connecting rod 4043 to rotate together. The second end 40432 of the third connecting rod 4043 drives the second pivot plate 4032 to rotate around the rotation center 40321 of the second pivot plate 4032. Driven by the first connecting rod 4033, the first pivot plate 4031 can rotate around the rotation center 40311 of the first pivot plate 4031, realizing the rotation of the first pivot plate 4031 and the second pivot plate 4032 together, and further realizing the rotation of the channel 4034 around the second end 40342 of the channel 4034.

[0111] In the initial state, the ends of the first pivot plate 4031 and the second pivot plate 4032 close to the turnover bin 402 (i.e., the first end 40341 of the channel 4034) are at the lowest position (see Figure 6 ), and at this time the channel 4034 is basically in a horizontal state.

[0112] The driving component 405 operates, driving the first pivot plate 4031 and the second pivot plate 4032 to rotate upward together, realizing the upward rotation of the first end 40341 of the channel 4034, and the channel 4034 starts to tilt (see Figure 7 ), and tilts until the highest position (see Figure 8 ). The driving component 405 operates, continuing to drive the rotating shaft 4041 to rotate, and the channel 4034 passes over the highest position and starts to fall back (see Figure 9 ), and finally returns to the initial state as shown in Figure 6 . During the rotation of the channel 4034, the reaction cups inside can be moved so that they can smoothly enter the channel slide 5.

[0113] Of course, the rotating shaft 4041 can also rotate in the reverse direction, and the channel 4034 rotates in sequence as Figure 6 , Figure 9 , Figure 8 , Figure 7 , Figure 6 .

[0114] The above embodiments introduce the principle of how the reaction cups obtain driving power in the channel 4034 (that is, how the connecting rod mechanism 404 ensures that the reaction cups can smoothly pass through the channel 4034). Next, it introduces how the turnover assembly 4 realizes the orientation of the reaction cups.

[0115] As shown in Figure 14 and Figure 15As shown, a baffle 4035 is provided at one end of the first pivot plate 4031 close to the slideway 5, which can block a part of the outlet of the channel 4034. A channel groove 4036 is provided at one end of the upper surface of the second pivot plate 4032 close to the slideway 5. Side plates 4037 are provided on both sides of the second pivot plate 4032. The two side plates 4037 can be pivotally connected to the mounting plate 401 and rotate around the rotation center 40321. The second pivot plate 4032 is fixed between the two side plates 4037 and rotates synchronously with the two side plates 4037 around the rotation center 40321. The upper edges 40371 of the two side plates 4037 protrude upward from the second pivot plate 4032 by a preset distance. The upper edges 40371 of the side plates 4037 are exactly connected to the upper edge 504 of the slideway 5 to ensure that the reaction cup 9 slides into the slideway 5.

[0116] An outer edge is provided at the cup mouth of the reaction cup 9. The maximum outer diameter of the outer edge of the cup mouth is greater than the outer diameter of the cup body. The distance between the two side plates 4037 is less than the maximum outer diameter of the cup mouth of the reaction cup and greater than the outer diameter of the cup body. The combined action of the side plates 4037, the baffle 4035 and the channel groove 4036 causes the reaction cup with the cup mouth facing the slideway 5 to be flipped so that the cup bottom faces the slideway 5, that is, the orientation of the reaction cup is realized.

[0117] Before introducing the orientation, first introduce the problem of the distance change between the baffle 4035 and the channel groove 4036. Since the baffle 4035 and the channel groove 4036 rotate around different rotation centers, the distance between them will change during the rotation process. Figure 10 is Figure 6 The front view after omitting one side plate 4037 and the first connecting rod 4033. Figure 11 is Figure 8 The front view after omitting one side plate 4037 and the first connecting rod 4033 shows that when the channel 4034 rotates to the lowest position (refer to Figure 10 ), the distance between the baffle 4035 and the channel groove 4036 is the largest, and when the channel 4034 rotates to the highest position (refer to Figure 11 ), the distance between the baffle 4035 and the channel groove 4036 is the smallest.

[0118] There are two situations for the reaction cup entering the channel 4034. The first is that the cup mouth faces outward (i.e., towards the first end 40341 of the channel 4034), and the second is that the cup mouth faces inward (i.e., towards the second end 40342 of the channel 4034). Since the reaction cup needs to have the cup mouth facing upward when it falls into the distribution tray 6 in actual application, it is necessary to adjust for the second situation to ensure that the cup mouths of the reaction cups falling into the slideway 5 all face outward.

[0119] When the mouth of the reaction cup entering the channel 4034 faces outward (i.e., towards the first end 40341 of the channel 4034), driven by the link mechanism 404, the reaction cup naturally enters the slideway 5.

[0120] Specifically, as Figure 16 , the mouth of the reaction cup 9 is stuck above the upper edge 40371 of the side plate 4037. When the reaction cup 9 slides from Figure 16 's state to Figure 17 , the body of the reaction cup begins to tilt into the channel groove 4036 and continues to slide to Figure 18 's state. In Figure 18 , the channel 4034 rotates to Figure 19 's state driven by the link mechanism 404, and then falls into the slideway 5 by gravity.

[0121] When the mouth of the reaction cup 9 entering the channel 4034 faces inward (i.e., towards the second end 40342 of the channel 4034), from Figure 20 slides to Figure 21 's position. Since the distance between the two side plates 4037 is less than the maximum outer diameter of the outer extension of the mouth of the reaction cup 9, the outer extension of the mouth is always blocked above the upper edge 40371 of the side plate 4037 and will not fall into the channel groove 4036. Therefore, the mouth of the reaction cup 9 will be blocked by the baffle 4035 (see Figure 21 ).

[0122] The channel 4034 continues to rotate, and the distance from the baffle 4035 to the channel groove 4036 begins to increase. The body of the cup begins to fall into the channel groove 4036 (see Figure 22 ), and then the reaction cup 9 continues to slide to Figure 23 , Figure 24 , Figure 25 , Figure 27 , Figure 28 's state, realizing the rotation of the channel 4034 to drive the reaction cup 9 to flip from the state with the mouth facing inward to the state with the mouth facing outward.

[0123] Furthermore, the cup inlet structure further includes a second transfer component 7. The bottom plate of the silo 2 is provided with an opening 205 (see Figure 2 ). The second transfer component 7 is installed on the opening 205 of the bottom plate of the silo 2. That is, the second transfer component 7 and the bottom plate of the silo 2 together form the bottom of the silo 2. The second transfer component 7 can transfer the reaction cups located in the silo 2 to the lower end of the first transfer component 3, facilitating the transfer by the first transfer component 3.

[0124] Exemplarily, the bottom plate of the silo 2 is set with a certain inclination, and the second transfer component 7 is inclinedly installed at the bottom of the silo 2. The inclined setting can transfer the reaction cups to the lower end of the first transfer component 3 more efficiently.

[0125] Exemplarily, as Figure 31 shown, the second transfer assembly 7 includes a conveyor belt 701 that rotates around shafts 702 and 703, thereby transferring the reaction cups located on the conveyor belt 701 in the silo 2.

[0126] The conveyor belt 701 can obtain the power of rotation by connecting a driving component through one of the shafts (shaft 702 or shaft 703). In addition, as Figure 32 shown, a transmission belt 8 can be added. The first transfer assembly 3 drives the second transfer assembly 7 to rotate through the transmission belt 8. The transmission process is as follows: The driving component 301 of the first transfer assembly 3 drives the shaft 304 to rotate, the shaft 304 drives the conveyor belt 303 to rotate, the conveyor belt 303 drives the shaft 305 to rotate, the shaft 305 drives the transmission belt 8 to rotate, and the transmission belt 8 drives the shaft 702 to rotate, thereby driving the conveyor belt 701 to rotate.

[0127] Furthermore, as Figure 2 shown, the silo 2 is equipped with a first sensor 201 for sensing whether the number of reaction cups in the silo 2 is lower than a preset warning line. When the first sensor 201 senses that the number of reaction cups in the silo 2 is lower than the preset warning line, an alarm is given to notify the staff to add reaction cups to the silo 2.

[0128] Furthermore, as Figure 5 shown, a second sensor 4021 is installed on the turnover bin 402. On the one hand, the second sensor 4021 can sense whether the number of reaction cups in the turnover bin 402 is lower than a preset warning line. When it senses that the number of reaction cups in the turnover bin 402 is lower than the preset warning line, it notifies the relevant controller to control the first transfer assembly 3 to work and transfer the reaction cups in the silo 2 into the turnover assembly 4. On the other hand, the second sensor 4021 can count the reaction cups passing through the turnover bin.

[0129] Furthermore, as Figure 30 shown, a third sensor 501 is provided on the slideway 5. When the third sensor 501 senses that the slideway 5 is in a state of lacking cups, it notifies the relevant controller to control the link mechanism 404 in the turnover assembly 4 to work and transfer the reaction cups in the turnover bin 402 into the slideway 5.

[0130] Furthermore, as Figure 30 shown, there are 3 reaction cup placement positions 602 in the distribution tray 6. A fourth sensor 601 is provided on the distribution tray 6. When the fourth sensor 601 senses that a reaction cup placement position 602 lacks a cup, it notifies the relevant controller to control the distribution tray 6 to rotate for turnover, thereby achieving the purpose of transferring reaction cups.

[0131] Furthermore, as Figure 29As shown in the figure, an arc-shaped groove 505 is provided at one end of the side plate 503 of the slideway 5 close to the channel assembly 403. The arc-shaped groove 505 is matched with the shape of one end of the side plate 4037 of the channel assembly 403 to ensure the normal rotation of the side plate 4037 of the channel assembly 403.

[0132] The following will further describe the usage process of the cup feeding structure of the present invention.

[0133] The staff stores a large number of reaction cups in the bin 2. The second transfer assembly 7 transfers the reaction cups in the bin 2 to the lower end of the first transfer assembly 3, and transfers them to the upper end of the first transfer assembly 3 through the first transfer assembly 3, and then transfers them to the turnover bin 402 of the turnover assembly 4.

[0134] The reaction cups in the turnover bin 402 enter the first end 40341 of the channel 4034 of the channel assembly 403 through the outlet 4023 at the bottom. The connecting rod mechanism 404 is started to drive the first end 40341 of the channel 4034 to rotate upward, realizing the rotation of the channel 4034, and transferring the reaction cup located at the first end 40341 of the channel 4034 to the second end 40342 of the channel 4034.

[0135] When the cup mouth of the reaction cup entering the channel 4034 faces outward, the cup mouth of the reaction cup 9 is stuck above the upper edge 40371 of the side plate 4037, and the cup body of the reaction cup 9 falls into the channel groove 4036, and then falls into the slideway 5 by gravity.

[0136] When the cup mouth of the reaction cup 9 entering the channel 4034 faces inward, the cup mouth of the reaction cup 9 will be blocked by the baffle 4035 (see Figure 21 ), and the cup body of the reaction cup 9 is flipped to the state where the cup mouth faces outward in the channel groove 4036.

[0137] The oriented reaction cup 9 slides into the slideway 5 from the second end 40342 of the channel 4034 (the cup mouth is still stuck on the upper edge 504 of the slideway 5, and the cup body falls into the space between the two slideway side plates 504), and then falls into the distribution tray 6 through the slideway 5.

[0138] During the operation, when the first sensor 201 senses that the number of reaction cups in the bin 2 is lower than the preset warning line, an alarm is given to notify the staff to add reaction cups into the bin 2.

[0139] When the second sensor 4021 senses that the number of reaction cups in the turnover bin 402 is lower than the preset warning line, it notifies the relevant controller to control the first transfer assembly 3 to work and transfer the reaction cups in the bin 2 into the turnover assembly 4. On the other hand, the second sensor 4021 can count the reaction cups passing through the turnover bin.

[0140] When the third sensor 501 senses that the chute 5 is in a state of lacking reaction cups, it notifies the relevant controller to control the linkage mechanism 404 in the turnover assembly 4 to operate, and transfer the reaction cups in the turnover bin 402 into the chute 5.

[0141] When the fourth sensor 601 senses the lack of reaction cups, it notifies the relevant controller to control the rotation of the distribution disk 6 for turnover, so as to achieve the purpose of transferring reaction cups.
