Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

Referring to fig. 1 to 3, fig. 1 shows a schematic structural view of a decapping device according to an embodiment of the present invention, fig. 2 shows a schematic structural view of the lifting mechanism 40, the first clamping mechanism 20 and the rotating mechanism 70 in fig. 1, and fig. 3 shows a schematic structural view of the first clamping mechanism 20 and the rotating mechanism 70 in fig. 1. An embodiment of the present invention provides a decapping device for decapping a sampling container 10, where the sampling container 10 includes a container body and a cover openably disposed on the container body. The uncapping device comprises: a first clamping mechanism 20, a second clamping mechanism 30, a lifting mechanism 40, and a sensing device 50. The first clamping mechanism 20 is used to clamp the lid. The second clamping mechanism 30 is for clamping the container body. The lifting mechanism 40 is connected to the first clamping mechanism 20 and is used for driving the first clamping mechanism 20 to move up and down so as to move the first clamping mechanism 20 to the clamping position and the disengagement position. The sensing device 50 is used to sense whether the first clamping mechanism 20 clamps the cover when operating to the disengaged position.

It should be noted that the clamping position and the disengaging position are explained as follows, when the first clamping mechanism 20 is driven by the lifting mechanism 40 to move up and down to the clamping position, the first clamping mechanism 20 can clamp the cover on the sampling container 10; when the first holding mechanism 20 is driven by the lifting mechanism 40 to move up and down to the disengaged position, that is, the cover held by the first holding mechanism 20 is in a separated and disengaged state from the container body held by the second holding mechanism 30.

When the uncapping device needs to uncapping the sampling container 10, the cover of the sampling container 10 can be separated from the container body by enabling the first clamping mechanism 20 to run to the clamping position and clamp the cover, enabling the second clamping mechanism 30 to clamp the container body, and then driving the first clamping mechanism 20 to lift through the lifting mechanism 40 to drive the cover to move to the separating position; on the contrary, when the sampling container 10 needs to be capped, the lifting mechanism 40 can drive the first clamping mechanism 20 to move up and down to move the lid from the releasing position to the clamping position, so that the lid gradually approaches to the container body and is mounted on the container body. In addition, when the first clamping mechanism 20 drives the cover to move to the separation position, whether the first clamping mechanism 20 clamps the cover or not is sensed through the sensing device 50, if the first clamping mechanism 20 clamps the cover, the success of uncapping the sampling container 10 is indicated, and otherwise the failure is indicated. Therefore, the automatic uncapping operation and the automatic capping operation of the sampling container 10 can be realized, whether the uncapping is successful or not can be detected, and the working efficiency is high.

Referring again to fig. 1, in one embodiment, the sensing device 50 is specifically disposed on the frame 93 or the first support plate 46, for example. The height position of the sensing device 50 is, for example, the same as the height of the disengagement position to which the first clamping mechanism 20 moves the cover, and the sensing device 50 is, for example, a photoelectric sensor. When the clamping jaw 24 of the first clamping mechanism 20 drives the cover to move to the disengaging position, laser emitted by the photoelectric sensor is emitted to the clamping jaw 24, if the clamping jaw 24 does not clamp the cover, a gap exists in the clamping jaw 24, and the emitted light can not be reflected back after passing through the gap; if the cover is clamped by the clamping jaw 24, no gap exists in the clamping jaw 24, and the emitted light can be reflected by the cover clamped by the clamping jaw 24 and can be sensed by the photoelectric sensor.

Referring to fig. 1-3, in one embodiment, the decapping device further comprises a scanning element 60. The scanning head of the scanning element 60 faces the outer wall surface of the sampling container 10 and is used for acquiring the information code on the outer wall surface of the sampling container 10. Specifically, the information code includes, but is not limited to, a two-dimensional code, a barcode, or other patterns capable of storing information and scanning. In this way, the uncapping device not only has the uncapping and capping functions, but also can obtain the information code of the sampling container 10 through the scanning piece 60, so that the automation degree is improved.

Referring to fig. 1 to 3, in one embodiment, the uncapping apparatus further includes a rotating mechanism 70 disposed between the lifting mechanism 40 and the first clamping mechanism 20. The lifting mechanism 40 is connected to the rotating mechanism 70, and the rotating mechanism 70 is connected to the first holding mechanism 20. In this way, the first clamping mechanism 20 can be lifted and lowered by the lifting mechanism 40, so that the uncapping operation and the capping operation can be performed correspondingly; the information code on the outer wall surface of the sampling container 10 can be conveniently scanned and acquired, namely, the cover is clamped by the first clamping mechanism 20, for example, the first clamping mechanism 20 is driven to rotate by the rotating mechanism 70, when the first clamping mechanism 20 is driven to rotate by the rotating mechanism 70, the sampling container 10 can be correspondingly driven to rotate, and the information code on the outer wall surface of the sampling container 10 can be acquired in the process that the sampling container 10 rotates for a circle. It can be understood that, after the first clamping mechanism 20 clamps the cover, the lifting mechanism 40 is firstly operated to drive the first clamping mechanism 20 to clamp the sampling container 10 to ascend, so that the sampling container 10 is completely separated from the sample tray 91, and then the sampling container 10 is driven to rotate, so as to obtain the information code on the outer wall of the sampling container 10.

Referring to fig. 1-3, in one embodiment, the uncapping apparatus further comprises a frame 93. The lifting mechanism 40, the rotating mechanism 70 and the first clamping mechanism 20 are disposed on the frame 93.

The lifting mechanism 40 is only required to provide power to drive the first clamping mechanism 20 to lift, and includes, but is not limited to, a motor screw drive, a motor belt drive, an air cylinder drive, a hydraulic cylinder drive, and the like, and the specific structure is not limited herein. In one example, the lifting mechanism 40 includes a first motor 41, a first lead screw 42, a first screw 43, a first slide rail 44, a first slider 45, and a first support plate 46. The first motor 41 is connected to a first lead screw 42. The first screw 43 is sleeved on the first screw 42, and the first screw 43 is connected with the first sliding block 45. The first sliding block 45 is slidably disposed on the first sliding rail 44, and the first sliding block 45 is connected to the first supporting plate 46. The first slide rail 44 is disposed on the frame 93, and the first motor 41 is disposed on the first slide rail 44 or the frame 93. Thus, when the first motor 41 works, the first screw 42 drives the first slider 45 to drive the first support plate 46 to move up and down along the first slide rail 44.

The rotating mechanism 70 is only required to provide power to drive the first clamping mechanism 20 to rotate, and the specific structure is not limited herein. In one embodiment, the rotating mechanism 70 includes a second motor 71 disposed on the first support plate 46, a first driving wheel 72 and a first driven wheel 73 rotatably disposed on the first support plate 46, and a first transmission element 74 connecting the first driving wheel 72 and the first driven wheel 73, wherein the second motor 71 is connected to the first driving wheel 72. Thus, when the second motor 71 works, the first driving wheel 72 and the first transmission element 74 drive the first driven wheel 73 to rotate, and when the first driven wheel 73 rotates, the first clamping mechanism 20 is correspondingly driven to rotate.

The first clamping mechanism 20 is only required to clamp and release the cover, and the specific structure is not limited herein. In one embodiment, the first clamping mechanism 20 includes a third motor 21 disposed on the first support plate 46, a second lead screw (not shown), a second screw sleeve (not shown), a second slide rail (not shown), a second slider (not shown), a pushing shaft 22, at least two link assemblies 23, and at least two clamping jaws 24. A third motor 21 is connected to the second lead screw. The second screw sleeve is sleeved on the second screw rod and connected with the second sliding block. The second slide block is slidably disposed on a second slide rail, the second slide rail and the first support plate 46. The second slider is further connected to a pushing shaft 22, the pushing shaft 22 penetrates through the first driven wheel 73 along the central axis of the first driven wheel 73 and can move along the central axis relative to the first driven wheel 73, and the end of the pushing shaft 22 is rotatably connected to one end of the connecting rod assembly 23. The connecting rod assembly 23 is correspondingly connected with the clamping jaw 24. The first driven pulley 73 is connected to the link assembly 23 via the connecting plate 25. Therefore, when the third motor 21 works, the third motor 21 drives the second screw sleeve to move through the second lead screw, the second screw sleeve drives the second sliding block to move along the second sliding rail, the second sliding block synchronously drives the pushing shaft 22 to move, the connecting rod assembly 23 is pushed to move when the pushing shaft 22 moves, the clamping jaw 24 can be loosened and clamped when the connecting rod assembly 23 moves, and the cover can be clamped and loosened. In addition, since the end of the pushing shaft 22 is rotatably connected to one end of the connecting rod assembly 23, the first driven wheel 73 is connected to the connecting rod assembly 23 through the connecting plate 25, that is, the pushing shaft 22 acts to push the connecting rod assembly 23 to move, and the pushing shaft 22 does not interfere with the rotating motion of the connecting rod assembly 23 and the clamping jaw 24, so that the first driven wheel 73 drives the connecting rod assembly 23 and the clamping jaw 24 to rotate smoothly through the connecting plate 25.

In one embodiment, the decapping device further comprises a first position sensor (not shown). The first position sensor is disposed on the frame 93, and is used for sensing a moving position of the first supporting plate 46, and the first position sensor is electrically connected to the first motor 41. Therefore, according to the sensing signal of the first position sensor, the lifting height position of the first supporting plate 46 can be accurately controlled, the sampling container 10 installed in the sample tray 91 can be accurately moved upwards by a preset distance, and the sampling container 10 can be moved downwards and placed back into the sample tray 91.

In one embodiment, the first position sensor is, for example, a first correlation sensor fixedly disposed on the frame 93. The first correlation sensor is provided with a transmitting end and a receiving end, and the transmitting end transmits the optical signal to the receiving end for receiving. Be provided with first baffle (not marking in the figure) on first backup pad 46, under elevating system's 40 drive, first baffle shelters from the emitted light of first correlation sensor when moving the position of first correlation sensor to make first correlation sensor sense first baffle, just can acquire the preset position that first backup pad 46 moved when sensing first baffle promptly, and calibrate elevating system 40.

Referring to fig. 1-3, in one embodiment, the uncapping apparatus further comprises a second position sensor 81. The second position sensor 81 is disposed on the first supporting plate 46, the second position sensor 81 is used for sensing a rotation position of the first driven wheel 73, and the second position sensor 81 is electrically connected to the second motor 71. Therefore, the rotating position of the first driven wheel 73 can be correspondingly judged according to the sensing signal of the second position sensor 81, and when the code scanning step is performed, the rotating position is combined with the second position sensor 81 to control the second motor 71 to drive the container body to rotate for at most one circle.

Referring to fig. 1, 4 and 5, fig. 4 is a schematic view illustrating a perspective structure of the second clamping mechanism 30 in fig. 1; fig. 5 shows another perspective structure diagram of the second clamping mechanism 30 in fig. 1. In one embodiment, the uncapping apparatus further comprises a frame 93. The second clamping mechanism 30 includes a second supporting plate 31 mounted on the frame 93, a fourth motor 32 and a third slide rail 33 disposed on the second supporting plate 31, a third slider 34 slidably disposed on the third slide rail 33, a third supporting plate 35 connected to the third slider 34, two clamping arms 36 rotatably disposed on the third supporting plate 35, an elastic member (not shown) abutting between the two clamping arms 36 to open the two clamping arms 36, a fourth slide rail 37 disposed on the third supporting plate 35, a fourth slider 38 slidably disposed on the fourth slide rail 37, a third screw 391 connected to the fourth motor 32, and a third screw sleeve 392 sleeved on the third screw 391. The third threaded sleeve 392 is connected to the fourth slider 38. The fourth slider 38 is provided with a pushing portion which moves along the fourth slide rail 37 in the direction of the gripper arms 36 to push the two gripper arms 36 so that the two gripper arms 36 grip the container body. Thus, when the fourth motor 32 is operated in a clamping mode, under the guiding action of the third slider 34 and the third slide rail 33, the third support plate 35 drives the fourth slide rail 37, the fourth slider 38 and the two clamping arms 36 to move towards the sampling container 10, when the two clamping arms 36 contact the container body, the third support plate 35 stops moving, the fourth slider 38 continues moving towards the container body, and in the moving process, the two clamping arms 36 are pushed by the pushing portion to enable the two clamping arms 36 to clamp the container body; on the contrary, when the container body needs to be loosened and clamped, the fourth motor 32 drives the fourth slider 38 to move in the direction away from the container body, the pushing part and the two clamping arms 36 are separated from each other in the moving process, the two clamping arms 36 are opened under the action of the elastic part, so that the container body is loosened, and when the fourth motor 32 continues to act, the fourth slider 38 and the third supporting plate 35 both sequentially move back and reset.

Referring to fig. 1, 4 and 5, in one embodiment, the pushing portion is two rollers 381 rotatably disposed on the fourth slider 38. The two holding arms 36 are each provided with an inclined surface 361 abutting against the roller 381 and inclined with respect to the pushing direction of the pushing portion, and the distance between the two inclined surfaces 361 increases along the pushing direction of the pushing portion. In this way, when the two rollers 381 move along the two inclined surfaces 361 toward the container body, the two inclined surfaces 361 can be pushed, so that the two holding arms 36 clamp the container body; conversely, when the two rollers 381 move along the direction of the two inclined surfaces 361 away from the container body, the two holding arms 36 are reset under the urging action of the elastic member after the rollers 381 leave the inclined surfaces 361.

Referring to fig. 1, 4 and 5, in one embodiment, the third supporting plate 35 is provided with a first limiting portion 351 for limiting and matching with the frame of the fourth motor 32, and a second limiting portion 352 for limiting and matching with the fourth sliding block 38. That is, in the process that the fourth motor 32 drives the two holding arms 36 to move towards the container body, since the pushing portion of the fourth slider 38 is abutted against the inclined surfaces 361, the elastic force provided by the elastic member between the two holding arms 36 acts on the two inclined surfaces 361, so as to prevent the fourth slider 38 from moving towards the container body, so that the third supporting plate 35 firstly moves towards the container body, and when the two holding arms 36 are moved to the position where they contact the outer wall of the container body, the first limiting portion 351 is abutted against the frame of the fourth motor 32 for limiting, and thus the movement cannot be continued; after the third supporting plate 35 stops moving, the fourth motor 32 continues to work to drive the fourth sliding block 38 to move towards the container body, and the pushing part of the fourth sliding block 38 correspondingly pushes the two clamping arms 36 to clamp the container body; in addition, when the fourth motor 32 works in the reverse direction, the fourth slider 38 drives the pushing portion to leave the inclined surface 361, and meanwhile, when the fourth slider 38 moves to the position abutting against the second limiting portion 352, the fourth slider 38 stops sliding relative to the fourth sliding rail 37, but the fourth motor 32 still works, so that the third supporting plate 35 moves and resets.

Referring to fig. 1, 4 and 5, in one embodiment, the uncapping apparatus further includes a third position sensor 82 disposed on the second supporting plate 31. The third position sensor 82 is used for sensing the moving position of the third supporting plate 35, and the third position sensor 82 is electrically connected with the fourth motor 32. In this way, when the second supporting plate 31 moves to the starting position (which can be set according to actual requirements), the third position sensor 82 can sense the position accordingly, and control the fourth motor 32 to stop working. The third position sensor 82 is provided as a third correlation sensor, similar to the first position sensor. The third correlation sensor is provided with a transmitting end and a receiving end, and the transmitting end transmits the optical signal to the receiving end for receiving. The third baffle 353 is arranged on the third supporting plate 35, and the third supporting plate 35 drives the third baffle 353 to shield the emitted light of the third correlation sensor when the third correlation sensor is moved to the position of the third correlation sensor, so that the third correlation sensor senses the third baffle 353 and correspondingly controls the fourth motor 32 to stop working when the third baffle 353 is sensed.

Referring to fig. 1, in one embodiment, the decapping device further comprises a sample tray 91 and a fifth motor 92. The sample tray 91 is used to house the sampling containers 10. A fifth motor 92 is connected to the sample tray 91 for driving the sample tray 91 to rotate. So, under the drive of fifth motor 92, can realize driving sample dish 91 and rotate, will need to carry out the sampling container 10 adjustment that uncaps when sample dish 91 rotates and target in place, need not artifical manual adjustment sample dish 91's position, can realize automatically that each sampling container 10 on the sample dish 91 all accomplishes the operation such as uncapping, sweep the sign indicating number, sample, dress lid.

Referring to fig. 1-3, in one embodiment, a medical testing analyzer includes a decapping device according to any of the embodiments described above.

When the medical detection analyzer needs to perform uncapping operation on the sampling container 10, the cover of the sampling container 10 can be separated from the container body by enabling the first clamping mechanism 20 to operate to the clamping position and clamp the cover, enabling the second clamping mechanism 30 to clamp the container body, and then driving the first clamping mechanism 20 to move up and down through the lifting mechanism 40 to drive the cover to move to the separating position; on the contrary, when the sampling container 10 needs to be capped, the lifting mechanism 40 can drive the first clamping mechanism 20 to move up and down to move the lid from the releasing position to the clamping position, so that the lid gradually approaches to the container body and is mounted on the container body. In addition, when the first clamping mechanism 20 drives the cover to move to the separation position, whether the first clamping mechanism 20 clamps the cover or not is sensed through the sensing device 50, if the first clamping mechanism 20 clamps the cover, the success of uncapping the sampling container 10 is indicated, and otherwise the failure is indicated. Therefore, the automatic uncapping operation and the automatic capping operation of the sampling container 10 can be realized, whether the uncapping is successful or not can be detected, and the working efficiency is high.
