Description

Clamping device and detection equipment

Technical Field

The invention relates to the technical field of in-vitro diagnosis medical equipment, in particular to a clamping device and detection equipment.

Background

In vitro diagnosis, IVD (In Vitro Diagnosis), refers to products and services for detecting human body samples (blood, body fluid, tissue, etc.) outside the human body to obtain clinical diagnosis information and further to determine disease or body function. With the development of technology, automatic equipment is gradually used for replacing manual operation in-vitro diagnosis so as to ensure efficiency.

In the conventional art, when performing in-vitro diagnosis, a sample tube is generally clamped by a clamping device so that a cap of the sample tube can be rotated by a cap opening device.

However, the clamping force of the existing clamping device is not well controlled when clamping the sample tube, and the clamping force is too small to easily cause that only part of the sample tube is clamped, and the clamping force is too large to easily damage the sample tube.

Referring to fig. 1, fig. 1 is a schematic axial view of a clamping device according to an embodiment of the present invention, in which a clamping device 10 is provided to adaptively clamp a plurality of sample tubes 20, respectively, that is, the clamping device 10 is capable of providing an appropriate clamping force to firmly clamp each sample tube 20. The clamping device 10 includes a displacement assembly 100, a plurality of contacts 200, and a plurality of elastic members 300. The plurality of contacts 200 are each connected to the displacement assembly 100 and move with the displacement assembly 100 for respectively clamping the plurality of sample tubes 20. The plurality of elastic members 300 are correspondingly connected between the plurality of contact members 200 and the displacement assembly 100, that is, one ends of the plurality of elastic members 300 are connected with the displacement assembly 100, and the other ends of the plurality of elastic members 300 are respectively connected with the corresponding contact members 200. The plurality of contacts 200 move in the direction of the compression elastic member 300 independently of each other when they are correspondingly abutted against the sample tube 20.

In the clamping device 10, the displacement assembly 100 can drive the plurality of contacts 200 to move so as to clamp the plurality of sample tubes 20 correspondingly. Since the contact 200 is in contact with the sample tube 20 and abuts the sample tube 20, the contact 200 can compress the elastic member 300 under the reaction of the sample tube 20. Correspondingly, the elastic member 300 is also capable of elastically pushing the contact member 200 so as to keep the contact member 200 in close contact with the sample tube 20. In this way, the clamping force of the contact 200 for clamping the sample tube 20 can be adaptively adjusted, so that the contact 200 can be ensured to firmly clamp the sample tube 20.

Further, since the plurality of elastic members 300 are correspondingly connected between the plurality of contacts 200 and the displacement assembly 100, the plurality of contacts 200 can compress the corresponding elastic members 300 independently of each other after the contacts 200 abut the sample tube 20. That is, each contact 200 is capable of independently compressing its corresponding elastic member 300, so that each elastic member 300 can be deformed differently. That is, in the above-mentioned clamping device 10, any of the contacts 200 can independently and adaptively clamp the sample tubes 20, so that each sample tube 20 can be firmly clamped in a targeted manner, and a plurality of sample tubes 20 can be clamped at the same time.

Still further, a plurality of contacts 200 are each coupled to the displacement assembly 100 for movement with the displacement assembly 100, i.e., the displacement assembly 100 is capable of simultaneously driving the plurality of contacts 200 to move toward or away from the sample tube 20. This reduces the power source required within the clamp 10 relative to independently driving the movement of the contact 200 by a separate power source, resulting in a simple, compact and less costly overall structure of the clamp 10.

With respect to the contact 200 compressing the elastic member 300, it should be noted that the contact 200 may be a passive compression of the elastic member 300. Specifically, when the contact 200 is in contact abutment with the sample tube 20, the position of the contact 200 is unchanged relative to the sample tube 20. At this time, the displacement assembly 100 is still moving, so that the distance between the displacement assembly 100 and the contact 200 can be reduced to compress the elastic member 300 connected between the contact 200 and the displacement assembly 100.

Referring to fig. 1, in one embodiment, the clamping device 10 further includes a base 400, and a guide shaft 410 is disposed on the base 400. The displacement assembly 100, the elastic member 300 and the contact member 200 are sequentially and movably sleeved on the guide shaft 410. So configured, on the one hand, the guide shaft 410 can limit and guide the movement of the contact member 200, so that the contact member 200 can move to a desired position along a desired direction, thereby ensuring accurate alignment with the sample tube 20. On the other hand, by simultaneously fitting the displacement assembly 100 and the contact 200 over the guide shaft 410, the relative positions of the two can be defined, and the contact 200 can be stably moved with the displacement assembly 100.

Meanwhile, the elastic member 300 is sleeved on the guide shaft 410, and the guide shaft 410 can limit the position of the elastic member 300 in the axial direction. That is, when the contact 200 moves in the direction of compressing the elastic member 300, the elastic member 300 can be stably abutted against the displacement assembly 100 and the contact 200 at both ends thereof under the restriction of the guide shaft 410, respectively, so as to stably provide an elastic force to the contact 200, thereby ensuring the self-adaptive clamping of the contact 200.

Of course, in some embodiments, the elastic member 300 may not be sleeved on the guide shaft 410. Some connection limiting structure may be provided on the side of the displacement assembly 100 adjacent to the contact 200 or between the displacement assembly 100 and the contact 200 to define the position of the resilient member 300.

Further, the elastic member 300 is located between the displacement assembly 100 and the contact member 200. Then, when the displacement assembly 100 is moved in a direction approaching the contact 200, the contact 200 can be moved by pushing the contact 200 by the elastic member 300 so that the contact 200 approaches the sample tube 20. In other words, the provision of the elastic member 300 between the displacement assembly 100 and the contact member 200 can also be used for transmission for transmitting the movement of the displacement assembly 100 to the contact member 200.

The elastic member 300 may be a compression spring, so as to elastically abut between the displacement assembly 100 and the contact member 200.

With continued reference to fig. 1, in one embodiment, the base 400 further includes a mating member 420. The contact member 200 moves in a direction approaching the mating member 420 to clamp the sample tube 20 together with the mating member 420, and the contact member 200 compresses the elastic member 300 in a direction away from the mating member 420. Specifically, the mating member 420 may be positioned on a side of the contact member 200 remote from the displacement assembly 100, and the sample tube 20 may be positioned between the contact member 200 and the mating member 420. When the displacement assembly 100 moves in a direction approaching the contact 200, the contact 200 can be pushed to move together by the elastic member 300 to move in a direction approaching the mating member 420.

When the contact 200 contacts the sample tube 20, the fitting 420 can support the sample tube 20 in a stable position, so that the sample tube 20 can react to the contact 200, which can make the contact 200 not further displace, while the displacement assembly 100 still moves in a direction approaching the contact 200, so that the distance between the displacement assembly 100 and the contact 200 decreases, i.e., the contact 200 can compress the spring in a direction away from the fitting 420. In this manner, the elastic member 300 can generate elastic force to keep the contact member 200 in close contact with the sample tube 20.

When the displacement assembly 100 moves away from the contact 200, the displacement assembly 100 is able to pull the contact 200 along with it to separate the contact 200 from the sample tube 20, causing the elastic member 300 to relax.

In some embodiments, the mating member 420 may be integrally formed with the base 400, or the contact member 200 may directly interact with the base 400 to collectively clamp the sample tube 20.

With continued reference to fig. 1, in one embodiment, the displacement assembly 100 includes a pushing member 110 and a connecting member 120. The pushing member 110 is movably disposed on the guide shaft 410, the elastic member 300 is sleeved on the guide shaft 410, and two ends of the elastic member 300 are respectively elastically abutted against the pushing member 110 and the contact member 200. When the pushing member 110 moves in a direction approaching the contact member 200, the contact member 200 is pushed to move together by the elastic member 300 so as to approach and press the sample tube 20.

The connecting piece 120 is connected with the pushing piece 110, and the connecting piece 120 is abutted with one side surface, far away from the pushing piece 110, of the contact piece 200. As such, when the pusher 110 moves away from the contact 200, the connector 120 is able to pull the contact 200 along with the pusher 110 to move away from the mating member 420 and release the sample tube 20 due to the abutment of the connector 120 with the contact 200.

It should be noted that the connection member 120 and the contact member 200 may be separately disposed. In this manner, the link 120 does not restrict the movement of the contact 200 in a direction approaching the pusher 110. In other words, referring to the pusher 110, after the contact 200 contacts the sample tube 20, the contact 200 can move in a direction approaching the pusher 110 with respect to the pusher 110. That is, by providing the contact member 200 in contact with the contact member 120 to a side away from the pushing member 110 and the contact member 200 being separable from the contact member 120, the contact member 200 is not only capable of moving along with the displacement assembly 100, but also capable of generating displacement in a direction approaching the displacement assembly 100 from the reaction of the sample tube 20 to compress the elastic member 300.

With continued reference to fig. 1, in one embodiment, the contact 200 includes a body 210 and at least one wing 220 coupled to the body 210. The portion of the connecting member 120 away from the pushing member 110 abuts against a side of the wing plate 220 away from the pushing member 110 to pull the contact member 200 to move with the pushing member 110 in a direction away from the mating member 420.

In one embodiment, the number of connectors 120 corresponds to the number of contacts 200, with one connector 120 being connected to all of the wings 220 on the same contact 200 to ensure independence of movement between the individual contacts 200. Of course, in some embodiments, a plurality of connectors 120 may be provided corresponding to one contact 200.

With continued reference to fig. 1, in one embodiment, the base 400 includes a bottom plate 430, a first support plate 440 and a second support plate 450, the first support plate 440 and the second support plate 450 are connected to the bottom plate 430, and the first support plate 440 and the second support plate 450 are disposed opposite to each other. Both ends of the guide shaft 410 are connected to the first support plate 440 and the second support plate 450, respectively. The mating member 420 may be specifically and fixedly disposed on the second supporting plate 450, and one end of the guiding shaft 410 may also be threaded through the mating member 420, so that the contact member 200 moves to a position aligned with the mating member 420 along the guiding shaft 410.

Referring to fig. 1, in one embodiment, the number of the guide shafts 410 is plural, and the guide shafts 410 are connected to the base 400 side by side and at uniform intervals, i.e. the guide shafts 410 are connected between the first support plate 440 and the second support plate 450 side by side and at uniform intervals. One contact 200 may be correspondingly sleeved on two or more guide shafts 410 to avoid deflection of the contact 200 relative to the guide shafts 410.

In one embodiment, all of the guide shafts 410 may be movably disposed through the pushing member 110 so that each of the guide shafts 410 guides and positions each of the contacts 200.

Referring to fig. 1, in one embodiment, the clamping device 10 further includes a driving member 500. The driving member 500 is coupled to the guide shaft 410 to drive the guide shaft 410 to rotate. The guide shaft 410 is provided with a first screw structure (not shown, the same applies hereinafter), and the pushing member 110 is provided with a second screw structure (not shown, the same applies hereinafter). The first screw structure cooperates with the second screw structure to drive the movement of the pusher 110 when the guide shaft 410 rotates. That is, when the guide shaft 410 rotates, the pushing member 110 is driven to move along the axial direction of the guide shaft 410 by the cooperation of the first screw structure and the second screw structure, so as to drive the contact member 200 to move along with the first screw structure, so that the contact member 200 cooperates with the mating member 420 to realize the opening and clamping actions.

It will be appreciated that the contact member 200 clamps the sample tube 20 by the elastic force of the elastic member 300, and also effectively reduces the rate of motor locking failure in the driving member 500.

In one embodiment, the first thread structure is provided on the guide shaft 410 only in a partial region, so as to avoid the thread structure affecting the guiding limit of the guide shaft 410 to the contact 200.

In one embodiment, the first thread structure may be an internal thread structure, and the second thread structure may be an external thread structure correspondingly matched with the first thread structure. I.e. the guide shaft 410 may be a screw.

Of course, in some embodiments, the clamping device 10 may also include a transmission (not shown, below). The driving member 500 is connected to a transmission member, which is connected to the pushing member 110. In this way, the movement of the driver 500 can be transmitted to the pusher 110 via the transmission element. The transmission mode of the transmission member and the pushing member 110 can be gear-rack transmission, cam transmission, etc.

In other embodiments, the driving member 500 may also be directly connected to the pushing member 110 to drive the pushing member 110 to reciprocate. In this case, the driving element 500 may be a linear actuator such as an air cylinder, a hydraulic cylinder, or an electric push rod.

Referring to fig. 1, in one embodiment, the sides of the contact element 200 and the mating element 420 facing each other are respectively concavely provided with a first clamping portion 211 and a second clamping portion 421, and the first clamping portion 211 and the second clamping portion 421 are used for adaptively clamping the sample tube 20. The first clamping portion 211 and the second clamping portion 421 may be provided in a groove structure capable of adapting to the outer shape of the sample tube 20, such as a V-groove or an arc-groove.

With continued reference to fig. 1, in one embodiment, the first buffer pad 700 is disposed on each side of the first clamping portion 211 and the second clamping portion 421, which are close to each other, so as to prevent the sample tube 20 from being damaged and to more tightly support the position of the sample tube 20. Specifically, the first cushion 700 is a flexible member, and the first cushion 700 is capable of being deformed adaptively under compression. The first cushion pad 700 may be made of flexible materials such as rubber and silica gel.

With continued reference to FIG. 1, in one embodiment, the clamping device 10 further includes a cup 600, the cup 600 being hollow for receiving the sample tube 20. It will be appreciated that the sample tube 20 can be initially positioned by the cup 600 so that the contact member 200 cooperates with the mating member 420 to collectively grip the sample tube 20.

The number of the cups 600 may correspond to the number of the contacts 200, and a plurality of cups 600 are used to receive the sample tubes 20 in a one-to-one correspondence to perform preliminary positioning of all the sample tubes 20.

The cup 600 may be specifically disposed on the base, and projections of the contact 200 and the mating member 420 on the base are located on two sides of the cup 600 respectively.

The embodiment of the invention also provides detection equipment, which comprises a clamping device 10, a cover opening device, a grabbing device and a detection device. The gripping device is used to grip the sample tube 20 and is placed in the cup 600 of the holding device 10. The gripping device 10 is capable of gripping the sample tube 20 and the uncapping device is capable of opening the cap of the sample tube 20 located on the gripping device 10. The detection device is used for detecting substances in the sample tube.

In one embodiment, the holding device 10 further comprises a second cushion (not shown, the same applies below) provided on the inner wall of the cup holder 600. The second buffer pad is adapted to abut the sample tube 20. It will be appreciated that the gripping device typically also includes a depressing action when placing the sample tubes 20 into the cup holder 600 so that all of the sample tubes 20 can be within the same predetermined height, facilitating the engagement of the contact 200 and the engagement member 420 with each other for gripping. By providing the second buffer pad on the inner wall of the cup holder 600, the second buffer pad can play a role in buffering the sample tube 20 when the sample tube 20 is inserted into the cup holder 600, so as to avoid the sample tube 20 from directly contacting the bottom wall and/or the side wall of the cup holder 600 to be damaged by collision.

The second cushion pad can be a cushion material such as pearl wool, felt and the like.

Specifically, the cup holder 600 includes a bottom wall and an inner peripheral wall, and the bottom wall and the inner peripheral wall may be provided with second cushioning pads for cushioning and protecting the sample tube 20. Of course, in some embodiments, the second cushion may be provided only on the bottom wall of the cup holder 600.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

The above examples illustrate only a few embodiments of the invention, which are described in detail and are not to be construed as limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention. Accordingly, the scope of protection of the present invention is to be determined by the appended claims.
