Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a sample holder conveying device. Background Technology

[0002] In conducting various types of tests related to patient diagnosis and treatment, medical institutions need to collect biological fluid samples from human or animal patients, such as urine, serum, plasma, cerebrospinal fluid, and similar substances, for testing and analysis. Generally, test tubes are used to load and store biological fluid samples, and the test tubes are placed on test tube racks. A conveyor mechanism continuously transports the test tubes between different tests. However, the existing technology can only transport the test tube rack to a designated position, and it cannot accurately transport each test tube. In particular, when loading materials, the sample in a single tube can only be placed manually onto the testing equipment. Utility Model Content

[0003] This invention provides a sample holder conveying device, which can improve the accuracy of sample conveying and also improve the convenience of testing.

[0004] To solve the above-mentioned technical problems, this utility model provides a sample holder conveying device, comprising:

[0005] The mounting bracket has at least one resting surface for placing a sample holder. The bottom of the sample holder has at least a plurality of receiving openings. The mounting bracket is provided with a slide rail extending along a predetermined direction.

[0006] A connecting bracket is movably mounted on the slide rail, and a limiting component is provided on the connecting bracket;

[0007] A drive mechanism is connected to the connecting bracket, and the drive mechanism is capable of driving the connecting bracket to reciprocate in the preset direction;

[0008] A shift fork component is rotatably mounted on the connecting bracket to allow the shift fork component to rotate in a vertical plane. A limiting component is positioned on one side of the shift fork component to keep the shift fork component in an inclined state. The limiting component is used to limit the shift fork component so that the shift fork component can rotate in a first direction while restricting the shift fork component from rotating in a second direction. The second direction is the opposite of the first direction. The first direction is consistent with the inclination direction of the shift fork component. When the shift fork component is in an inclined state, the top end of the shift fork component extends into the receiving opening.

[0009] As a preferred embodiment of the above technical solution, the top of the shift fork component is formed with a sharp end, and the two sides of the sharp end are formed with bevels.

[0010] As a preferred embodiment of the above technical solution, the driving mechanism includes a drive motor, a synchronous belt, and synchronous pulleys. There are two synchronous pulleys, which are rotatably mounted on the mounting bracket. The synchronous belt is tensioned on the two synchronous pulleys and is fixedly connected to the connecting bracket. The drive motor is connected to either of the two synchronous pulleys.

[0011] As a preferred embodiment of the above technical solution, the mounting bracket is further provided with a reset mechanism, which is used to limit the reciprocating stroke of the connecting bracket.

[0012] As a preferred embodiment of the above technical solution, the mounting bracket is further provided with a pressing mechanism, which is elastically pressed onto the sample holder.

[0013] As a preferred embodiment of the above technical solution, the reset mechanism includes a sensing component and an optocoupler. The sensing component is disposed on the connecting bracket so that the sensing component can move with the connecting bracket. The optocoupler is fixed on the mounting bracket, and the sensing component and the optocoupler are disposed correspondingly.

[0014] As a preferred embodiment of the above technical solution, the optocoupler has a sensing port formed thereon, and the sensing component is formed in the bent portion of the connecting bracket, wherein the bent portion can extend into the sensing port during the movement of the connecting bracket.

[0015] As a preferred embodiment of the above technical solution, the pressing mechanism includes a movable component, a pressing wheel, and an elastic component. The movable component is rotatably mounted on the mounting bracket, the pressing wheel is rotatably mounted on the movable component, and the two ends of the elastic component are respectively connected to the movable component and the elastic component. The pressing wheel is elastically pressed onto the base of the sample holder.

[0016] As a preferred embodiment of the above technical solution, the mounting bracket includes a first vertical plate, a second vertical plate, and a connecting base plate. The first vertical plate and the second vertical plate are vertical and parallel to each other. The connecting base plate is connected to the first vertical plate and the second vertical plate respectively. The slide rail is disposed on the inner surface of the first vertical plate. The movable component is installed on the inner surface of the second vertical plate. The first vertical plate and the connecting base plate are integrally bent. The upper end of the first vertical plate is bent to form an upper bent portion. The upper surface of the upper bent portion is the resting plane. The side of the connecting base plate away from the first vertical plate is bent upward to form a bent connecting portion. The bent connecting portion is detachably connected to the second vertical plate.

[0017] As a preferred embodiment of the above technical solution, the top of the second vertical plate is bent toward the first vertical plate to form a mounting bending portion, and a positioning bracket is detachably mounted on the top of the mounting bending portion.

[0018] This utility model provides a sample rack conveying device, which includes a mounting bracket, a connecting bracket, a driving mechanism, and a fork component. During sample transfer, the sample rack is placed on a resting surface on the mounting bracket. The sample rack has multiple neatly arranged receiving compartments, each containing a collection tube. The bottom surface of the sample rack base has a receiving opening corresponding to each receiving compartment, and the upper surface of the base has an arc-shaped groove corresponding to each receiving compartment. The fork component is rotatably mounted on the connecting bracket and is tilted under the restraint of a limiting component. When the sample rack is in its initial position, the tip of the fork component extends into the receiving opening at the bottom of the first receiving compartment. The driving mechanism then drives the connecting bracket... The frame moves in the opposite direction of the tilt. Due to the blocking effect of the limiting component, the fork component cannot rotate in the opposite direction of the tilt. Therefore, the fork component can drive the sample frame to move forward a set distance, which can be the spacing of a cell. At this time, the drive mechanism drives the connecting bracket to move in the opposite direction, that is, in the tilt direction. Since the fork component is tilted and the limiting component no longer restricts the rotation of the fork component in the reverse movement state, the fork component will further rotate and tilt when the connecting bracket moves in the reverse direction until it enters the receiving opening corresponding to the next receiving cell. This repeated operation can ensure that each receiving cell is conveyed, improving the accuracy of conveying and the convenience of loading during the conveying test. Attached Figure Description

Detailed Implementation

[0027] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] See Figure 1 and Figure 2 As shown, in this embodiment, the sample holder 200 has a plurality of neatly arranged receiving grids 2002, each receiving grid 2002 containing a collection tube 300, and receiving openings 2004 corresponding to the receiving grids 2002 are formed on the bottom surface of the base 2001 of the sample holder 200, and arc-shaped grooves 2003 are formed on the upper surface of the base 2001, with the arc-shaped grooves 2003 corresponding to the receiving grids 2002.

[0029] See Figures 3 to 7 As shown, this embodiment provides a sample rack conveying device, including:

[0030] Mounting bracket 10, with at least a resting surface 107 formed on the mounting bracket 10, the resting surface 107 for placing sample rack 200, the bottom of sample rack 200 having at least a plurality of receiving openings 2004, and a slide rail 40 extending along a preset direction provided on the mounting bracket 10.

[0031] A connecting bracket 30 is movably mounted on a slide rail 40, and a limit component 301 is provided on the connecting bracket 30.

[0032] The drive mechanism 20 is connected to the connecting bracket 30, and the drive mechanism 20 can drive the connecting bracket 30 to reciprocate in a preset direction;

[0033] The shift fork component 50 is rotatably mounted on the connecting bracket 30 so that the shift fork component 50 can rotate in a vertical plane. The limiting component 301 is blocked on one side of the shift fork component 50 so that the shift fork component 50 is kept in an inclined state. The limiting component 301 is used to limit the shift fork component 50 so that the shift fork component 50 can rotate in a first direction and restrict the shift fork component 50 from rotating in a second direction. The second direction is the opposite of the first direction. The first direction is consistent with the inclined direction of the shift fork component 50. When the shift fork component 50 is in an inclined state, the top end of the shift fork component 50 extends into the receiving opening 2004.

[0034] This embodiment provides a sample holder conveying device, which includes a mounting bracket 10, a connecting bracket 30, a driving mechanism 20, and a fork component 50. During sample transfer, the sample holder 200 is placed on the resting surface 107 of the mounting bracket 10. The fork component 50 is rotatably mounted on the connecting bracket 30, and is tilted under the restraint of the limiting component 301. When the sample holder 200 is in its initial position, the top of the fork component 50 extends into the receiving opening 2004 at the bottom of the first receiving compartment 2002. The driving mechanism 20 drives the connecting bracket 30 to move in the opposite direction of the tilt. Due to the obstruction of the limiting component 301, the fork component 50 cannot move in the opposite direction of the tilt. The fork component 50 rotates, thus driving the sample holder 200 to move forward a set distance, which can be the spacing of a compartment 2002. At this time, the drive mechanism 20 drives the connecting bracket 30 to move in the opposite direction, that is, in the tilting direction. Since the fork component 50 is tilted and the limiting component 301 no longer restricts the rotation of the fork component 50 in the reverse movement state, the fork component 50 will further rotate and tilt until it enters the receiving opening 2004 corresponding to the next compartment 2002 when the connecting bracket 30 moves in the reverse direction. This repeated operation can ensure that each compartment 2002 is conveyed, improving the accuracy of conveying and the convenience of feeding during the conveying test. In addition, its operation is more stable.

[0035] In a further embodiment of this invention, a sharp end 501 is formed at the top of the shift fork component 50, and inclined surfaces 502 are formed on both sides of the sharp end 501.

[0036] In this embodiment, the sharp end 501 has beveled surfaces 502 on both sides, which makes it easier to insert the sharp end 501 into the receiving opening 2004 and prevents jamming.

[0037] In a further embodiment of this invention, the drive mechanism 20 includes a drive motor 201, a synchronous belt 203, and synchronous pulleys 202. There are two synchronous pulleys 202, which are rotatably mounted on the mounting bracket 10. The synchronous belt 203 is tensioned on the two synchronous pulleys 202 and is fixedly connected to the connecting bracket 30. The drive motor 201 is connected to either of the two synchronous pulleys 202.

[0038] In this embodiment, the synchronous belt 203 is driven to rotate by the synchronous pulley 202 driven by the drive motor 201. The drive mechanism 20 works more smoothly and can achieve its reciprocating movement during operation more smoothly.

[0039] In a further embodiment of this invention, a reset mechanism 100 is also provided on the mounting bracket 10, which is used to limit the travel of the reciprocating movement of the connecting bracket 30.

[0040] In a further embodiment of this invention, the mounting bracket 10 is also provided with a pressing mechanism 70, which is elastically pressed onto the sample holder 200.

[0041] In this embodiment, the pressing mechanism 70 provides a downward elastic force to the sample holder 200, which can effectively prevent the fork component 50 from driving the sample holder 200 backward during the retraction process.

[0042] In a further embodiment of this invention, the reset mechanism 100 includes a sensing component 302 and an optocoupler 60. The sensing component 302 is disposed on the connecting bracket 30 so that the sensing component 302 can move with the connecting bracket 30. The optocoupler 60 is fixed on the mounting bracket 10. The sensing component 302 and the optocoupler 60 are disposed correspondingly.

[0043] In a further embodiment of this invention, an induction port is formed on the optocoupler 60, and the sensing component 302 is a bent portion formed on the connecting bracket 30. During the movement of the connecting bracket 30, the bent portion can extend into the induction port.

[0044] In a further embodiment of this invention, the pressing mechanism 70 includes a movable part 701, a pressing wheel 702, and an elastic part 703. The movable part 701 is rotatably mounted on the mounting bracket 10, the pressing wheel 702 is rotatably mounted on the movable part 701, and the two ends of the elastic part 703 are respectively connected to the movable part 701 and the elastic part 703. The pressing wheel 702 is elastically pressed onto the base 2001 of the sample holder 200.

[0045] In a further embodiment of this invention, the mounting bracket 10 includes a first vertical plate 102, a second vertical plate 105, and a connecting base plate 103. The first vertical plate 102 and the second vertical plate 105 are vertical and parallel to each other. The connecting base plate 103 is connected to the first vertical plate 102 and the second vertical plate 105 respectively. The slide rail 40 is disposed on the inner surface of the first vertical plate 102. The movable part 701 is installed on the inner surface of the second vertical plate 105. The first vertical plate 102 and the connecting base plate 103 are integrally bent. The upper end of the first vertical plate 102 is bent to form an upper bent portion 101. The upper surface of the upper bent portion 101 is a resting plane 107. The side of the connecting base plate 103 away from the first vertical plate 102 is bent upward to form a bent connecting portion 104. The bent connecting portion 104 is detachably connected to the second vertical plate 105.

[0046] In a further embodiment of this invention, the top of the second vertical plate 105 is bent toward the first vertical plate 102 to form a mounting bending portion 106, and a positioning bracket 80 is detachably mounted on the top of the mounting bending portion 106.

[0047] In this embodiment, the positioning bracket 80 can achieve rapid positioning of the sample holder 200.
