[0037] The embodiment of the utility model provides a clamping device and a sample analyzer including the clamping device, which is used to solve the problems of high manufacturing precision, complex transmission structure and high cost caused by the clamping device using two standard guide rails to guide the movement of the clamping claws in the prior art.
[0038] In the embodiments of the present invention, please refer to Figure 1 The clamping device 1 includes a mounting base 10, a driving component 20, a first connecting component 30, a second connecting component 40, a first clamping jaw 80 and a second clamping jaw 90. One end of the first connecting component 30 is rotatably connected to the mounting base 10, the other end of the first connecting component 30 is connected to the first clamping jaw 80, one end of the second connecting component 40 is rotatably connected to the mounting base 10, and the other end of the second connecting component 40 is connected to the second clamping jaw 90. The driving component 20 is arranged on the mounting base 10, and the driving component 20 is used to drive the first connecting component 30 and the second connecting component 40 to rotate toward or away from each other, so as to drive the first clamping jaw 80 and the second clamping jaw 90 to move closer to or away from each other.
[0039] Among them, the first connecting component 30 and the second connecting component 40 can be set as various structures that can be connected between the first clamp 80 and the second clamp 90 and the driving component 20. They can be plates, rods, or a combination of plates and rods. They can also be one or more other structures that can play a connecting role, as long as they can drive the first clamp 80 and the second clamp 90 to move under the drive of the driving component 20.
[0040] The clamping device 1 adopts a first connecting component 30 and a second connecting component 40, which respectively drive the first clamping jaw 80 and the second clamping jaw 90 to move under the drive of the driving component 20. Compared with the direct-acting solution in the prior art, it eliminates the guide rail with high manufacturing precision requirements, has a simple structure, is easy to assemble, works reliably and has low cost.
[0041] In one embodiment, the first connecting assembly 30 and the second connecting assembly 40 each include at least one connecting rod, the connecting rod of the first connecting assembly 30 is connected between the mounting base 10 and the first clamp 80 , and the connecting rod of the second connecting assembly 40 is connected between the mounting base 10 and the second clamp 90 .
[0042] In a specific embodiment, the first connecting assembly 30 and the second connecting assembly 40 each include at least one connecting rod, and the connecting rod of the first connecting assembly 30 is fixedly connected to the first clamping jaw 80 , and the connecting rod of the second connecting assembly 40 is fixedly connected to the second clamping jaw 90 .
[0043] In another specific embodiment, the first connecting assembly 30 includes a first connecting rod 31 and a second connecting rod 32, the first connecting rod 31 is rotatably connected to the mounting seat 10 at a first connecting position, the first connecting rod 31 is rotatably connected to the first clamping jaw 80 at a second connecting position, the second connecting rod 32 is rotatably connected to the mounting seat 10 at a third connecting position, the second connecting rod 32 is rotatably connected to the first clamping jaw 80 at a fourth connecting position, and the line connecting the first connecting position and the second connecting position is parallel and equal in length to the line connecting the third connecting position to the fourth connecting position;
[0044] The second connecting assembly 40 includes a third connecting rod 41 and a fourth connecting rod 42. The third connecting rod 41 is rotationally connected to the mounting seat 10 at the fifth connecting position, the third connecting rod 41 is rotationally connected to the second clamp 90 at the sixth connecting position, the fourth connecting rod 42 is rotationally connected to the mounting seat 10 at the seventh connecting position, and the fourth connecting rod 42 is rotationally connected to the second clamp 90 at the eighth connecting position. The line connecting the fifth connecting position and the sixth connecting position is parallel to and is equal in length to the line connecting the seventh connecting position to the eighth connecting position.
[0045] In this embodiment, the line connecting the first connection position and the second connection position is parallel and equal to the line connecting the third connection position to the fourth connection position, which is equivalent to constructing a parallelogram structure together with the mounting base 10 and the first clamping jaw 80. When the first connecting rod 31 and the second connecting rod 32 rotate, the first clamping jaw 80 rotates relative to the first connecting rod 31 and the second connecting rod 32, so that the orientation of the opening on the first clamping jaw 80 for accommodating the test tube remains unchanged. Similarly, the orientation of the opening on the second clamping jaw 90 for accommodating the test tube remains unchanged. That is, during the rotation of the first clamping jaw 80 and the second clamping jaw 90, the openings of the first clamping jaw 80 and the second clamping jaw 90 are always directly opposite to each other. When the first clamping jaw 80 and the second clamping jaw 90 are close to the test tube, the two can be closed from both sides of the test tube with the openings directly opposite to each other, which can avoid the collision between the surrounding walls of the openings of the first clamping jaw 80 and the second clamping jaw 90 and the test tube. The centering is good, and the success rate of clamping the test tube is guaranteed.
[0046] It is easy to imagine that for the first connecting assembly 30 and the second connecting assembly 40, more than two parallel and equal-length connecting rods can be provided, and the effect is basically the same as that of the case with two connecting rods.
[0047] In one embodiment, the driving component 20 includes a rotating driving member 21, a cam 22 and an elastic member 23. The rotating driving member 21 is arranged on the mounting base 10, the cam 22 is connected to the output end of the rotating driving member 21, the cam 22 is arranged between the first connecting component 30 and the second connecting component 40, and the elastic member 23 is connected between the first connecting component 30 and the second connecting component 40. The elastic member 23 is used to generate a force that makes the first connecting component 30 and the second connecting component approach each other, so that the first connecting component 30 and the second connecting component 40 are respectively fitted with the side walls of the cam 22.
[0048] In this embodiment, the working process of the clamping device 1 is as follows: the rotating driving member 21 drives the cam 22 to rotate, and the raised portion on the cam 22 periodically pushes the first connecting component 30 and the second connecting component 40, so that the first connecting component 30 and the second connecting component 40 can overcome the force generated by the elastic member 23 and separate from each other, that is, the first clamping jaw 80 and the second clamping jaw 90 are separated from each other.
[0049] In this embodiment, the movement of the first jaw 80 and the second jaw 90 can be simultaneously controlled by a rotating driving member 21, which can simplify the structure and reduce costs; the cam 22 is used to drive the first jaw 80 and the second jaw 90 to move, and the movement of the first jaw 80 and the second jaw 90 is highly synchronized, which can improve the success rate of clamping; the elastic member 23 cooperates with the cam 22 on the one hand to realize the opening and closing movement of the first jaw 80 and the second jaw 90, and on the other hand provides clamping force so that the first jaw 80 and the second jaw 90 can clamp the test tube.
[0050] In a more specific embodiment, the elastic member 23 is configured as a spring, one end of the spring is connected to the first clamping jaw 80 , and the other end of the spring is connected to the second clamping jaw 90 .
[0051] The advantage of using springs is that they are low in cost and highly reliable, and the clamping force of the first jaw 80 and the second jaw 90 directly depends on the elastic coefficient of the spring and the amount of stretching generated by the push of the cam 22, and no complex control structure or control program is required to adjust the clamping force.
[0052] In another more specific embodiment, the elastic member 23 is configured as two magnetic members that can attract each other, one magnetic member is configured on the first clamping jaw 80, and the other magnetic member is configured on the second clamping jaw 90. The magnetic force generated between the two magnetic members causes the first clamping jaw 80 and the second clamping jaw 90 to tend to approach each other.
[0053] In a more specific embodiment, the rotary drive member 21 is configured as a stepping motor.
[0054] The advantages of using a stepper motor are that there is no cumulative error, simple structure, easy use and maintenance, and low manufacturing cost.
[0055] In a more specific embodiment, a first contact piece 50 is provided on the first connecting component 30, and a first contact arc surface is provided on the first contact piece 50, which protrudes in the direction of the cam 22, and the first contact arc surface is used to abut against the cam 22; a second contact piece 60 is provided on the second connecting component 40, and a second contact arc surface is provided on the second contact piece 60, which protrudes in the direction of the cam 22, and the second contact arc surface is used to abut against the cam 22.
[0056] In this embodiment, the cam 22 abuts against the first contact arc surface and the second contact arc surface, so that during the rotation of the cam, the distance between the first connecting component 30 and the cam 22 and the distance between the second connecting component 40 and the cam 22 can change smoothly, making the movement of the first connecting component 30 and the second connecting component 40 smoother and more stable, that is, making the movement of the first clamp 80 and the second clamp 90 smoother and more stable.
[0057] More specifically, the first contact member 50 and the second contact member 60 can both be configured as bolts, and the side surface of the bolt cap is used to form the first contact arc surface or the second contact arc surface.
[0058] The advantage of configuring the first contact member 50 and the second contact member 60 as bolts is that the bolts are low-cost, easy to obtain, and have their own threads. It is only necessary to open threaded holes in the first connecting component 30 and the second connecting component 40 to screw in the bolts, which is convenient to install and easy to replace.
[0059] More specifically, the first contact member 50 and the second contact member 60 can both be configured as rolling bearings, and the side surfaces of the rolling bearings are used to form the first contact arc surface or the second contact arc surface.
