Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a cup-grabbing device for a fully automated coagulation analyzer. Background Technology

[0002] In medical device sample analysis instruments, the rapid and reliable transfer of samples to various testing locations is essential. Therefore, a sample cup gripping and testing device is an indispensable component of the analytical instrument. A fast and reliable sample cup gripping and testing device can provide stable and efficient sample delivery for the testing equipment.

[0003] Currently, there are two main methods for handling sample cups. The first is to use vacuum suction to pick up the sample cup. This method requires a gas source and tubing, which takes up a lot of space and is not conducive to miniaturizing and lightening the instrument. The second method uses an electromagnet actuator to control the opening and closing of the gripper hooks to achieve the action of picking up and discarding the coagulation test cup. In this method, the electromagnet is external, which takes up a lot of space, and the frequent use of the electromagnet to control the opening and closing of the gripper hooks affects the lifespan of the components. Utility Model Content

[0004] The purpose of this invention is to provide a cup-grabbing device for a fully automated coagulation analyzer, which aims to solve the problem of existing sample cup grabbing devices occupying a large space.

[0005] To achieve the above objectives, this utility model provides a cup-grabbing device for a fully automated coagulation analyzer, including a detection position and a gripping assembly. The gripping assembly is disposed above the detection position and includes a base shell, an electromagnet, a return spring, a compression fixing block, a return guide block, and a gripper hook. The base shell is disposed above the detection position. The electromagnet is fixedly connected to the base shell and located on one side of the base shell. The gripper hook is disposed on the side of the base shell close to the electromagnet. The return spring is disposed on the side of the electromagnet away from the base shell. The compression fixing block is fixedly connected to the return spring and located on the side of the return spring away from the electromagnet. The return guide block is fixedly connected to the compression fixing block and located on the side of the compression fixing block away from the return spring.

[0006] The cup-gripping device for the fully automated coagulation analyzer also includes a synchronous reflection optical coupler, which is disposed on one side of the gripper hook.

[0007] The gripper hook includes a gripper body and a hook. The gripper body is disposed on the side of the base shell near the electromagnet, and the hook is fixedly connected to the gripper body and located on the side of the gripper body away from the base shell.

[0008] The gripping component further includes a tension spring, which is disposed on one side of the gripper body.

[0009] The compression fixing block includes a connecting block and a fixing block body. The connecting block is fixedly connected to the reset spring and is located on the side of the reset spring away from the electromagnet. The fixing block body is fixedly connected to the connecting block and is located on the side of the connecting block away from the reset spring.

[0010] This invention relates to a cup-grabbing device for a fully automated coagulation analyzer. The detection position is used to place the sample cup to be tested. The gripping component is precisely moved above the sample cup via a transmission device and then moves downwards to grip the sample cup. The sample cup is then transported to the detection position via the transmission device. The gripping component automatically grips and places the sample cup for testing by the detection device. The base shell provides installation conditions for the electromagnet and the gripper hooks. The gripping component uses a mechanical spring compression reset device to grip the sample cup. The electromagnet drives the cup release, enabling rapid completion of the gripping and releasing action. As the gripping component moves downwards, the upper ends of the sample cup push away the gripper hooks. At this time, the upper plane of the sample cup is in contact with the lower plane of the reset guide block, ensuring the gripping component... During operation, the sample cup remains stable. The reset guide block has a certain amount of elastic compression, which can prevent the gripping component from making hard contact with the sample cup when quickly gripping it, thereby reducing the occurrence of operational failures. The controller drives the electromagnet through a program. When the electromagnet is energized, it will drive the compression fixing block to move upward, so that the rounded corners on both sides of the compression fixing block push the inward V-shaped inclined surface of the gripper hook upward, opening the gripper hook and placing the sample cup into the detection position. During the entire operation, the electromagnet is only energized to open the gripper hook at the moment of placing the cup, avoiding the electromagnet from overheating due to prolonged energization, which would affect the service life of the electromagnet. The electromagnet of the gripping component is placed inside the base shell, making the device small in size and aesthetically pleasing, solving the problem of existing sample cup gripping devices occupying a large space.

Detailed Implementation

[0015] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0016] Please see Figures 1 to 2 This utility model provides a cup-grabbing device for a fully automated coagulation analyzer, including a detection position 1 and a gripping component 2. The gripping component 2 is disposed on the upper part of the detection position 1. The gripping component 2 includes a base shell 3, an electromagnet 4, a return spring 5, a compression fixing block 6, a return guide block 7, and a gripper hook 8. The base shell 3 is disposed on the upper part of the detection position 1. The electromagnet 4 is fixedly connected to the base shell 3 and located on one side of the base shell 3. The gripper hook 8 is disposed on the side of the base shell 3 close to the electromagnet 4. The return spring 5 is disposed on the side of the electromagnet 4 away from the base shell 3. The compression fixing block 6 is fixedly connected to the return spring 5 and located on the side of the return spring 5 away from the electromagnet 4. The return guide block 7 is fixedly connected to the compression fixing block 6 and located on the side of the compression fixing block 6 away from the return spring 5.

[0017] In this embodiment, the detection position 1 is used to place the sample cup 15 to be tested, and moves downward to grip the sample cup. The sample cup 15 is then transported to the bottom of the detection position 1 via a transmission device. The gripping component 2 is used to automatically grip the sample cup 15 and place it for testing by the detection device. The base shell 3 provides installation conditions for the electromagnet 4 and the gripper hook 8. When the gripping component 2 moves downward, the upper two ends of the sample cup 15 push away the gripper hook 8. At this time, the upper plane of the sample cup 15 is in contact with the lower plane of the reset guide block 7, ensuring that the sample cup 15 is stable when the gripping component 2 is running. The reset guide block 7 has a certain amount of elastic compression, which can prevent the gripping component 2 from gripping the cup too quickly. The sample cup 15 is in direct contact with the electromagnet 4, thereby reducing operational malfunctions. The controller drives the electromagnet 4 through a program. When the electromagnet 4 is energized, it moves the compression fixing block 6 upward, causing the rounded corners on both sides of the compression fixing block 6 to push the inward V-shaped inclined surface of the gripper hook 8 upward, opening the gripper hook 8 and placing the sample cup 15 into the detection position 1. During the entire operation, the electromagnet 4 is only energized to open the gripper hook 8 at the moment of placing the cup, avoiding the electromagnet 4 from overheating due to prolonged energization, which would affect the service life of the electromagnet 4. The electromagnet 4 of the gripping component 2 is placed inside the base shell 3, making the device small in size and aesthetically pleasing, and solving the problem of existing sample cup gripping devices occupying a large amount of space.

[0018] Furthermore, the cup-gripping device for the fully automated coagulation analyzer also includes a synchronous reflection optocoupler 9, which is disposed on one side of the gripper hook 8.

[0019] In this embodiment, the synchronous reflection optical coupler 9 and the gripping component 2 operate synchronously in the X and Y directions. The synchronous reflection optical coupler 9 is fixed in the Z direction. When the gripping component 2 grips the sample cup 15 and aligns with the synchronous reflection optical coupler 9 in the Z direction, the synchronous reflection optical coupler 9 can detect whether the gripping of the cup is successful, ensuring accurate and effective sample transfer.

[0020] Furthermore, the gripper hook 8 includes a gripper body 10 and a hook 11. The gripper body 10 is disposed on the side of the base shell 3 near the electromagnet 4, and the hook 11 is fixedly connected to the gripper body 10 and is located on the side of the gripper body 10 away from the base shell 3.

[0021] In this embodiment, the gripper body 10 is driven to open by the electromagnet 4 to grasp and lower the sample cup 15. The upper two ends of the sample cup 15 push open the hook 11, and the upper plane of the sample cup 15 fits with the lower plane of the reset guide block 7, ensuring that the sample cup 15 is stable when the gripping component 2 is running.

[0022] Furthermore, the gripping component 2 also includes a tension spring 12, which is disposed on one side of the gripper body 10.

[0023] In this embodiment, the tension spring 12 is provided so that when the electromagnet 4 stops, the gripper body 10 resets. Specifically, the electromagnet 4 drives the cup to be placed, which can quickly complete the cup gripping and placing action. The gripping component 2 moves downward, and the upper two ends of the sample cup 15 push open the gripper hooks 8. At this time, the tension spring 12 connecting the gripper hooks 8 on both sides is stretched. When the upper two ends of the sample cup 15 push past the gripper hooks 8, the gripper hooks 8 return to their original position under the action of the tension spring 12.

[0024] Furthermore, the compression fixing block 6 includes a connecting block 13 and a fixing block body 14. The connecting block 13 is fixedly connected to the reset spring 5 and is located on the side of the reset spring 5 away from the electromagnet 4. The fixing block body 14 is fixedly connected to the connecting block 13 and is located on the side of the connecting block 13 away from the reset spring 5.

[0025] In this embodiment, the connecting block 13 is used to connect the fixing block body 14 and the reset spring 5, wherein the fixing block body 14 is...

[0026] The above-disclosed embodiments are merely preferred embodiments of a cup-grabbing device for a fully automated coagulation analyzer and should not be construed as limiting the scope of this application. Those skilled in the art will understand that all or part of the processes for implementing the above embodiments, and equivalent variations made in accordance with the claims of this application, still fall within the scope of this application.
