[0028] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention can be combined with each other.

[0029] Please combine Figures 1 to 4 Now, the mixing device provided by the present invention is described. The mixing device is used in a specific protein analyzer.

[0030] The mixing device includes a first drive component 1, a second drive component 2, a third drive component 3, a clamping component 4, a first optical coupler component 5, a second optical coupler component 6, a third optical coupler component 7 and a sensor. The first drive component 1 is connected to the second drive component 2 and is used to drive the second drive component 2 to move in a first direction. The second drive component 2 is connected to the third drive component 3 and is used to drive the third drive component 3 to move in a second direction. The first direction and the second direction are set at an angle. The third drive component 3 is connected to the clamping component 4 and is used to drive the clamping component 4 to swing. The sensor is installed on the clamping component 4 and is used to sense the test tube 100. The first optical coupler component 5 is installed on the first drive component 1 and is used to sense the second drive component 2. The second optical coupler component 6 is installed on the second drive component 2 and is used to sense the third drive component 3. The third optical coupler component 7 is installed on the third drive component 3 and is used to sense the clamping component 4.

[0031] Specifically, the sensor is a miniature pressure sensor. The sensor is installed at the end of the jaw assembly 4 and is used to sense the opening and closing angle of the jaw assembly 4. As the opening and closing angle of the jaw assembly 4 changes, the sensor will output different electrical signals, and the software will determine whether the signal value is within the normal range. The specific judgment logic is as follows: measure the angle θ□ of the commonly used test tube 100 type, obtain the corresponding signal value V□, and set the deviation threshold ΔV′. When clamping the test tube 100, compare the true value V□ to determine whether there is a relationship of |V□-V□|≤ΔV′. If so, it means that the clamping is normal.

[0032] It can be understood that the first drive component 1 of the mixing device is connected to the second drive component 2 and is used to drive the second drive component 2 to move in a first direction. The second drive component 2 is connected to the third drive component 3 and is used to drive the third drive component 3 to move in a second direction. The first direction and the second direction are set at an angle. The third drive component 3 is connected to the clamping component 4 and is used to drive the clamping component 4 to swing, so that the sample in the test tube 100 is mixed. The sensor is installed on the clamping component 4 and is used to sense the test tube 100. The first optical coupler component 5 is installed on the first drive component 1 and is used to sense the second drive component 2. The second optical coupler component 6 is installed on the second drive component 2 and is used to sense the third drive component 3. The third optical coupler component 7 is installed on the third drive component 3 and is used to sense the clamping component 4. By arranging the sensor, the first optical coupler component 5, the second optical coupler component 6 and the third optical coupler component 7, the state of the test tube 100 is sensed according to the pressure signal and the state of each optical coupler component, thereby ensuring the safe use of the specific protein analyzer.

[0033] It should be noted that, depending on the placement of the mixing device, the first direction can be a horizontal direction or a vertical direction. For ease of understanding, in the relevant embodiments, the first direction is a horizontal direction, and the second direction is a vertical direction perpendicular to the first direction.

[0034] In this embodiment, the first optical coupling assembly 5 includes a first initial position optical coupler 51 and a first end position optical coupler 52. The first initial position optical coupler 51 and the first end position optical coupler 52 are spaced apart along a first direction on the first drive assembly 1. The first initial position optical coupler 51 is used to sense the initial position of the second drive assembly 2, and the first end position optical coupler 52 is used to sense the end position of the second drive assembly 2. The first drive assembly 1 drives the second drive assembly 2 to move from the first initial position optical coupler 51 to the first end position optical coupler 52. The second drive assembly 2 drives the third drive assembly 3 to move, and the third drive assembly 3 drives the clamping assembly 4 to move, so that the clamping assembly 4 can grasp the test tube 100.

[0035] Furthermore, the mixing device also includes a first shielding member, which is installed on the second drive assembly 2 and is used to shield the first initial position optical coupler 51 or the first end position optical coupler 52. The first drive assembly 1 drives the second drive assembly 2 to drive the first shielding member to move. The first shielding member can move from the first initial position optical coupler 51 to the first end position optical coupler 52, so as to shield the first initial position optical coupler 51 and the first end position optical coupler 52, so that the first initial position optical coupler 51 and the first end position optical coupler 52 send signals, thereby determining the positions of the second drive assembly 2, the third drive assembly 3 and the clamping jaw assembly 4.

[0036] In one embodiment, if Figure 1 As shown, the second optical coupler assembly 6 includes a second initial position optical coupler 61 and a second final position optical coupler 62. The second initial position optical coupler 61 and the second final position optical coupler 62 are spaced apart along the second direction on the second drive assembly 2. The second initial position optical coupler 61 is used to sense the initial position of the third drive assembly 3, and the second final position optical coupler 62 is used to sense the final position of the third drive assembly 3. The second drive assembly 2 drives the third drive assembly 3 from the second initial position optical coupler 61 to the second final position optical coupler 62. The third drive assembly 3 drives the clamping assembly 4 to move, so that the clamping assembly 4 can drive the test tube 100 away from the test tube rack 200.

[0037] Furthermore, the mixing device also includes a second shielding member 8, which is installed on the third drive assembly 3 and is used to shield the second initial position optical coupler 61 or the second end position optical coupler 62. The second drive assembly 2 drives the third drive assembly 3 to drive the second shielding member 8 to move. The second shielding member 8 can move from the second initial position optical coupler 61 to the second end position optical coupler 62, so as to shield the second initial position optical coupler 61 and the second end position optical coupler 62, so that the second initial position optical coupler 61 and the second end position optical coupler 62 send signals, thereby determining the position of the third drive assembly 3 and the clamping jaw assembly 4.

[0038] In one embodiment, continue as Figure 1As shown, the mixing device further includes a third shielding member 9, which is mounted on the clamping jaw assembly 4 and is used to shield the third optical coupler assembly 7. When the mixing device drives the clamping jaw assembly 4 to swing, the clamping jaw assembly 4 drives the third shielding member 9 to swing. The third shielding member 9 can shield the third optical coupler assembly 7 during the swinging process, thereby determining the swing position of the clamping jaw assembly 4.

[0039] In a related embodiment, the first optical coupling component 5 , the second optical coupling component 6 and the third optical coupling component 7 are all slot-type optical couplers.

[0040] It is necessary to add that:

[0041] Mixing preparation: The first blocking member blocks the first initial position optical coupler 51, the second blocking member 8 blocks the second initial position optical coupler 61, and the third blocking member 9 blocks the third optical coupler assembly 7, causing the gripper assembly 4 to be in the initial position. The sensor on the gripper assembly 4 does not sense a pressure signal. The first drive assembly 1 drives the second drive assembly 2 to move the first blocking member from the first initial position optical coupler 51 to the first end position optical coupler 52. The first blocking member blocks the first end position optical coupler 52, causing the second drive assembly 2 to drive the third drive assembly 3 and gripper assembly 4 to move, allowing the gripper assembly 4 to grip the test tube 100 on the test tube 100 rack. The sensor senses a normal pressure signal from the gripper assembly 4, indicating that the test tube 100 has been successfully gripped. Then, the second drive component 2 drives the third drive component 3 to move from the second initial position optocoupler 61 to the second end position optocoupler 62, the third drive component 3 drives the clamping component 4 to move, the clamping component 4 drives the test tube 100 away from the test tube 100 rack, and the first drive component 1 drives the second drive component 2 to drive the clamping component 4 back to the first initial position optocoupler 51 position.

[0042] Swinging and mixing: Initially, the third blocking member 9 blocks the third optical coupling component 7. The third driving component 3 drives the clamping claw component 4 to swing without blocking. After each action, the state of the third optical coupling component 7 and the sensor signal are judged.

[0043] Put the test tube 100 back: the first drive component 1 drives the second drive component 2 to move from the first initial position optocoupler 51 to the first end position optocoupler 52, and the second drive component 2 drives the third drive component 3 and the clamping component 4 to move. Then, the second drive component 2 drives the third drive component 3 to move from the second end position optocoupler 62 to the second initial position optocoupler 61, and the third drive component 3 drives the clamping component 4 to move, so that the clamping component 4 drives the test tube 100 to be placed in the test tube rack 200.

[0044] The present invention also provides a specific protein analyzer, which includes a sample injection platform 300, a test tube rack 200 and a mixing device according to any of the above embodiments. The test tube rack 200 injects samples from the sample injection platform 300 into the mixing device, and the mixing device mixes the test tubes 100 on the test tube rack 200.

[0045] It can be understood that the specific protein analyzer in this embodiment uses the above-mentioned mixing device, so that the first drive component 1 of the mixing device is connected to the second drive component 2 and is used to drive the second drive component 2 to move in a first direction. The second drive component 2 is connected to the third drive component 3 and is used to drive the third drive component 3 to move in a second direction. The first direction and the second direction are arranged at an angle. The third drive component 3 is connected to the clamping component 4 and is used to drive the clamping component 4 to swing, so that the sample in the test tube 100 is mixed. The sensor is mounted on the clamping component 4 and is used to sense the test tube 100. The first optical coupler component 5 is mounted on the first drive component 1 and is used to sense the second drive component 2. The second optical coupler component 6 is mounted on the second drive component 2 and is used to sense the third drive component 3. The third optical coupler component 7 is mounted on the third drive component 3 and is used to sense the clamping component 4. By providing the sensor, the first optical coupler component 5, the second optical coupler component 6 and the third optical coupler component 7, the state of the test tube 100 is sensed according to the pressure signal and the state of each optical coupler component, thereby ensuring the safety of use of the specific protein analyzer.

[0046] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0047] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention.
