Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the said features. In the description of the present invention, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.
[0041] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.
[0042] The transfer device of the present application belongs to the technical field of medical devices. In clinical testing instruments, such as coagulation analyzers, chemiluminescence analyzers (measurers), and other instruments that use reaction cups, during the testing process, it is necessary to transport the reaction cup from one work station to another and at the same time mix the sample in the reaction cup.
[0043] Generally speaking, the basic test process includes: 1. Adding samples and mixing reagents to the reaction cup; 2. Mixing the sample in the reaction cup through a mixing device; 3. Incubating the mixed sample and heating it to about 37 degrees; 4. Adding trigger reagent and mixing immediately; 5. After mixing, immediately move it to the measurement position for measurement and report the test results.
[0044] During the entire testing process, after adding the trigger reagent, the test cup must be moved to the test position for measurement within a very short time. Due to this short scheduling time, stringent requirements are placed on the software and hardware design of the instrument, resulting in occasional abnormalities in the instrument test results.
[0045] Existing instruments are generally implemented in two steps: first, they are transported by a gripper, and then an independent mixing mechanism is set up for mixing. Not only does the process take a long time and have low mixing efficiency, but it may also affect the accuracy of the measurement results.
[0046] like Figures 1 to 18As shown, according to the first aspect of the present application, the present application provides a reaction cup transfer device, which is used in an analyzer, and includes a transfer mechanism, a support mechanism 10, a gripper mechanism 20 and a drive mechanism 30, wherein the transfer mechanism is used to transfer the reaction cup to a specified position, the support mechanism 10 is installed in the transfer mechanism, the gripper mechanism 20 includes a gripper assembly 21 for grabbing the reaction cup and a connecting component 22 for connecting the gripper assembly 21 to the support mechanism 10, and the drive mechanism 30 includes a transmission assembly 32 and a drive assembly 31 installed on the support mechanism 10. In this embodiment, the connecting component 22 includes a first end 221 and a second end 222 opposite to the first end 221. The gripper assembly 21 is arranged on the first end 221 of the connecting component. The second end 222 of the connecting component is flexibly connected to the support mechanism 10. The transmission component 32 is connected to the output end of the driving component, and the transmission component 32 is connected to the position between the first end 221 and the second end 222 of the connecting component, so that the gripper assembly 21 performs a conical swing with the second end 222 of the gripper mechanism as the vertex, thereby achieving uniform mixing of the sample in the reaction cup on the gripper assembly 21.
[0047] Specifically, the transfer mechanism includes a longitudinal, transverse, and vertical motion assembly. The longitudinal motion assembly refers to the direction of forward and backward movement of the gripper assembly 21, the transverse motion assembly refers to the direction of left and right movement of the gripper assembly 21, and the vertical motion assembly refers to the direction of up and down movement of the gripper assembly 21. Therefore, the cuvette on the gripper assembly 21 can be moved to a designated location for measurement through the coordination of the longitudinal, transverse, and vertical motion assemblies of the transfer mechanism.
[0048] In addition, the transfer mechanism can also be a mechanical rocker arm, and the support mechanism 10 is installed on the mechanical rocker arm, so that the reaction cup on the gripper assembly 21 can be transferred to a designated position for measurement by the mechanical rocker arm.
[0049] After adopting the above technical solution, while the transfer device transfers the reaction cup to the designated position for measurement, the drive component 31 drives the reaction cup on the gripper component 21 to perform conical swing through the transmission component 32 to achieve uniform mixing of the sample in the reaction cup, so that the sample in the reaction cup is mixed when the reaction cup is transferred to the designated position, so that the mixed sample can be directly measured and the measurement result can be output, which not only improves the efficiency of sample mixing, but also reduces the occurrence rate of failure of the transfer device during the mixing process.
[0050] Since the transmission assembly 32 is connected between the first end 221 and the second end 222 of the connecting component, the transmission assembly 32 can transmit torque to the position between the first end 221 and the second end 222 of the connecting component, so that the gripper assembly 21 on the first end 221 can move around the second end 222 connected to the support mechanism 10, thereby achieving uniform mixing of the sample in the reaction cup on the gripper assembly 21, and also avoiding the phenomenon of insufficient axial mixing and upper and lower stratification of the sample in the reaction cup caused by circumferential mixing.
[0051] In an optional embodiment, the transmission assembly 32 is connected to the middle portion of the connecting member 22 between the first end 221 and the second end 222. In this embodiment, the first end 221 of the connecting member is disposed at the lower portion of the connecting member 22, the second end 222 of the connecting member is disposed at the upper portion of the connecting member 22, and the transmission assembly 32 is connected to the middle portion of the connecting member 22.
[0052] Specifically, the connecting component 22 is in the form of a long strip of plate, one end of which is flexibly connected to the support mechanism 10, and the other end is connected to the gripper assembly 21. A torque transmission part 223 is provided in the middle of the connecting component 22, and the transmission assembly 32 is connected to the torque transmission part 223, so that the torque output by the driving assembly 31 can be transmitted to the torque transmission part 223 through the transmission assembly 32, so that the connecting component 22 can perform a conical swinging motion with the connection between the second end 222 and the support mechanism 10 as the vertex, and then drive the sample in the reaction cup on the gripper assembly 21 to be mixed.
[0053] It should be noted that the connection between the transmission assembly 32 and the torque transmission part 223 can be a flexible connection or other transmission connection, which is not limited in this application. Its main purpose is to drive the connecting part 22 to perform a conical swinging motion with the second end 222 as the vertex.
[0054] In an optional embodiment, the driving assembly 31 includes a driving member 311 and an eccentric member 312, wherein the driving member 311 is mounted on the support mechanism 10 for providing output torque; the eccentric member 312 is connected between the output end of the driving member 311 and the transmission assembly 32, for driving the transmission assembly 32 to perform eccentric motion, so that the transmission assembly 32 can drive the connecting member 22 to perform conical swinging motion, and thereby drive the sample in the reaction cup on the gripper assembly 21 to be mixed.
[0055] Specifically, the driving member 311 includes a driving motor having an output shaft 311a. In this embodiment, the eccentric member 312 is provided with a first mounting portion 3121 and a second mounting portion 3122 which is eccentrically arranged with respect to the first mounting portion 3121, wherein the first mounting portion 3121 is mounted on the output shaft 311a through a machine screw 313, and the second mounting portion 3122 is connected to the transmission assembly 32 for driving the transmission assembly 32 to perform eccentric movement.
[0056] In an optional embodiment, the support mechanism 10 includes a mounting member 12 and a support member 11 . The mounting member 11 is installed in the transfer mechanism. One end of the support member 11 is installed on the mounting member 12 , and the connecting member 22 is installed on the other end of the support member 11 .
[0057] Specifically, the support member 11 includes a support body 112 and a rotating member 111. The second end of the connecting member 22 is flexibly connected to the support body 112 via the rotating member 111. The support body 112 is provided with a body mounting portion 1121 and a body rotation groove 1122. The rotating member 111 has a first rotating portion 1111 and a second rotating portion 1112, with the second rotating portion 1112 being perpendicularly connected to the first rotating portion 1111. In this embodiment, the support body 112 is mounted on the mounting member 12 via the body mounting portion 1121. The rotating member 111 is rotatably mounted in the body rotation groove 1122 via the first rotating portion 1111. The rotating member 111 is rotatably connected to the connecting member 22 via the second rotating portion 1112. This allows the driving member 311 to drive the transmission assembly 32 to perform eccentric motion via the eccentric member 312, thereby driving the connecting member 22 to perform a conical oscillating motion, thereby achieving uniform mixing of the sample in the cuvette on the gripper assembly 21.
[0058] In an optional embodiment, the first rotating portion 1111 is L-shaped, wherein the short section of the first rotating portion 1111 is connected to the second rotating portion 1112, and the long section of the first rotating portion 1111 extends toward the mounting member 12. A first rotating hole 1111a is provided at the corner of the first rotating portion 1111, and the support body 112 is hinged on the first rotating hole 1111a, so that the driving member 311 can only drive the connecting member 22 to perform a conical swinging motion in a direction away from the driving member 311, and can also play a positioning role. When the driving member 311 stops working, the connecting member 22 and the reaction cup can be under the action of gravity, and the long section of the first rotating portion 1111 abuts against the inner side of the support body 112, so that the connecting member 22 can be maintained in a direction perpendicular to the support body 112, thereby facilitating the removal and placement of the reaction cup on the gripper assembly 21.
[0059] In an optional embodiment, the second rotating portion 1112 is a rotating groove arranged on the rotating member 111, and the connecting component 22 can be rotatably mounted on the rotating groove through the locking shaft 113. This not only avoids the problems of jamming, speed reduction and unstable mixing effect of the connecting component 22 when performing conical swing, but also has a simple and practical structure, and is also convenient for manufacturing and assembly.
[0060] In addition, an elastic element may be provided on the support mechanism 10, that is, the connecting component 22 can be flexibly connected to the support mechanism 10 through the elastic element, wherein the elastic element can be a spring, and the elastic element can also be a connecting member made of other flexible materials. This application is not limited to this. Its main purpose is to enable the connecting component 22 to perform a conical swinging motion with the connection point between the connecting component 22 and the support mechanism 10 as the vertex.
[0061] In this embodiment, the elastic element is composed of multiple pairs of laminated springs. When the driving member 311 drives the connecting component 22 to perform a conical swinging motion through the transmission assembly 32, the elastic element can be expanded and contracted through the laminated layers between the springs, thereby avoiding problems such as jamming, deceleration, and unstable mixing effect of the connecting component 22 when performing a conical swing.
[0062] In an optional embodiment, the mounting member 12 is an L-shaped structure, wherein the support member 11 is mounted on the vertical end 121 of the mounting member, and the driving member 31 is mounted on the horizontal end 122 of the mounting member.
[0063] Specifically, a support member mounting hole 1211, a support member limiting platform 1212 and a mounting member mounting portion 1213 are provided on the vertical end 121 of the mounting member. The mounting member 12 is installed on the transfer mechanism through the mounting member mounting portion 1213. The horizontal end 122 of the mounting member is facing the direction of the connecting member 22. When the support member 11 is installed on the mounting member 12, the support member 11 is positioned by the support member limiting platform 1212, and then the support member 11 is fixed to the support member mounting hole 1211 by screws. The support member 11, the mounting member 12 and the connecting member 22 together constitute an installation space that can accommodate the driving member 31, so that the driving member 31 can be fixed on the horizontal end 122 of the mounting member. The design is reasonable and the structure is compact.
[0064] In an optional embodiment, a positioning through hole 1221 is provided on the horizontal end 122 of the mounting member, and a positioning boss 311b is provided on the driving member 311, wherein the positioning boss 311b is cooperated and connected with the positioning through hole 1221 to ensure the accurate position of the driving member 311 relative to the mounting member 12, and then the driving member 311 is fixed to the horizontal end 122 of the mounting member by screws, so that the driving member 311 can provide eccentric rotational power to the connecting member 22.
[0065] In an optional embodiment, the transmission assembly 32 includes a transmission member 321, which has a first thrust member 321a and a second thrust member 321b. The second thrust member 321b is arranged perpendicular to the first thrust member 321a, so that the driving member 311 can apply two forces to the connecting member 22 for spatial movement through the first thrust member 321a and the second thrust member 321b, respectively, thereby realizing the conical swinging motion of the connecting member 22, and then driving the sample in the reaction cup on the gripper assembly 21 to be mixed.
[0066] In an optional embodiment, the transmission assembly 32 also includes a limit member 322, which has a first slide groove 322a and a second slide groove 322b, wherein the limit member 322 is installed in the middle of the connecting part 22, the first thrust member 321a is slidingly connected to the first slide groove 322a, and the second thrust member 321b is slidingly connected to the second slide groove 322b to realize the conical swinging motion of the connecting part 22.
[0067] Specifically, the limit member 322 is installed on the torque transmission part 223 by fastening the screw 3221, and the first slide groove 322a and the second slide groove 332b are arranged vertically. When the driving member 311 is working, the eccentric member 312 drives the transmission member 321 to perform eccentric movement, so that the first thrust member 321a can slide along the first slide groove 322a, and the second thrust member 321b can slide along the second slide groove 322b, thereby driving the connecting member 22 to perform a conical swinging motion with the second end 222 as the vertex, thereby achieving mixing of the sample in the reaction cup on the gripper assembly 21.
[0068] In an optional embodiment, the transmission assembly 32 also includes a bearing member 323, wherein a bearing mounting portion 3211 is provided on the transmission member 321, the bearing member 323 is mounted on the bearing mounting portion 3211, and the second mounting portion 3122 is connected to the bearing member 323, so that when the eccentric member 312 can drive the transmission member 321 to perform eccentric movement through the bearing member 323, the eccentric member 312 can rotate more smoothly relative to the transmission member 321, avoiding unstable problems such as jamming and deceleration during the rotation of the eccentric member 312, thereby ensuring the mixing effect of the sample in the reaction cup.
[0069] Specifically, the transmission assembly 32 is provided with a bearing end cap 324, which is mounted on the bearing mounting portion 3211 and is used to secure the bearing member 323 to the bearing mounting portion 3211. In this embodiment, the bearing member 323 includes at least two rolling bearings. The bearing mounting portion 3211 is a bearing mounting hole provided in the transmission member 321. Both rolling bearings are mounted in the bearing mounting holes. The second mounting portion 3122 passes through the two rolling bearings and is secured with screws. The bearing end cap 324 is then secured to the transmission member 321 using locking screws 3241.
[0070] In an optional embodiment, to facilitate the processing and forming of the transmission member 321, a thrust shaft hole 3212 is provided on the transmission member 321, wherein the first thrust member 321a and the second thrust member 321b are both thrust shafts. In this embodiment, the first thrust member 321a is integrally formed with the transmission member 321, and the second thrust member 321b is assembled integrally with the transmission member 321 after passing through the thrust shaft hole 3212.
[0071] In an optional embodiment, the transfer device also includes a buffer member 40, which is connected between the support mechanism 10 and the connecting member 22, and is used to eliminate the gap between the transmission member 321 and the limit member 322, while playing a buffering role, reducing the tiny impacts between the various moving pairs, and making the movement softer.
[0072] Specifically, the buffer member includes a Z-shaped member 42 and a spring member 41. The Z-shaped member 42 is mounted on the support mechanism 10. One end of the spring member 41 is connected to the Z-shaped member 42, and the other end of the spring member 41 is connected to the connecting member 22. In this embodiment, the Z-shaped member 42 includes a first support plate 421 and a second support plate 422 that are parallel to each other. A third support plate 423 is connected between the first support plate 421 and the second support plate 422. A Z-shaped member mounting portion 1222 is provided on the horizontal end 122 of the mounting member. The second support plate 422 is mounted on the Z-shaped member mounting portion 1222 via screws. One end of the spring member 41 is fixed to the first support plate 421, and the other end is connected to the connecting member 22. The transmission assembly 32 is disposed between the first support plate 42 and the horizontal end 122 of the mounting member, resulting in a reasonable design and a compact structure.
[0073] In an optional embodiment, if Figure 18 As shown, the gripper assembly 21 includes a first gripper 211 and a second gripper 212. A jaw mounting portion is provided on the second end 222. The first gripper 211 is rotatably mounted on one side of the jaw mounting portion, while the second gripper 212 is rotatably mounted on the other side of the jaw mounting portion. The second gripper 212 is positioned opposite the first gripper 211 and is used to grasp a cuvette. When the first gripper 211 and the second gripper 212 move toward each other, they grip the cuvette; when they move away from each other, they release the cuvette. The structure is simple yet practical.
[0074] In an optional embodiment, the gripper assembly 21 further includes a reset member 213, which is disposed between the first clamp 211 and the second clamp 212. The toward or away movement of the first clamp 211 and the second clamp 212 can cause the reset member 213 to deform to clamp the reaction cup.
[0075] like Figures 1 to 18As shown, according to the second aspect of the present application, the present application provides a method for transferring a reaction cup, wherein the method for transferring the reaction cup is performed by the above-mentioned transfer device, and includes the following steps:
[0076] The transfer mechanism drives the gripper assembly 21 to grab the reaction cup and transfer it to the designated position;
[0077] When the transfer mechanism is transferring the cuvette, the driving assembly 31 drives the gripper assembly 21 through the transmission assembly 32 to cause the cuvette to swing in a conical shape with the second end of the connecting component 22 as the vertex until the sample in the cuvette is mixed.
[0078] When the reaction cup moves to the designated position for measurement, the sample in the reaction cup is mixed.
[0079] Specifically, the gripper assembly 21 grips the cuvette through the cooperation of the first gripper 211 and the second gripper 212, and the transfer mechanism drives the gripper assembly 21 to transfer the cuvette to a designated position. During the transfer mechanism driving the gripper assembly 21 to transfer, the drive assembly 31, via the transmission assembly 32, drives the connecting component 22 to perform a conical swinging motion with the second end 222 as the apex, thereby achieving uniform mixing of the sample in the cuvette on the gripper assembly 21. By the time the cuvette is moved to the designated position for measurement, the sample in the cuvette is fully mixed, allowing the mixed sample in the cuvette to be measured and the measurement results to be output. This not only improves the efficiency of sample mixing, but also reduces the incidence of malfunction of the transfer mechanism during the mixing process.
