Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, and more specifically, to a test tube righting and rotating device. In addition, the present invention also relates to a medical analyzer comprising the test tube righting and rotating device. Background Art

[0002] In the existing technology, high-end medical analyzers equipped with automatic sampling mechanisms generally have a device that can rotate the test tube so that the instrument can automatically scan the barcode attached to the test tube. The device can use a pressure head to press the test tube cap from the top of the test tube, and the friction between the pressure head and the test tube cap can drive the test tube to rotate.

[0003] The clearance between the currently commonly used test tube rack and the test tube placed in it causes the test tube to shake a certain amount in the test tube rack; when the rotating pressure head presses down on the test tube, it is easy for the pressure head to be misaligned with the center of the test tube to be rotated, or the edge of the pressure head contacts the adjacent test tube cap when pressing down, resulting in the inability to rotate the current test tube cap or the test tube cap being misdetected.

[0004] In summary, how to provide a test tube straightening and rotating device that can avoid inaccurate alignment between the pressure head and the test tube center during the downward pressing process of the pressure head is an urgent problem to be solved by those skilled in the art.

DETAILED DESCRIPTION

[0052] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0053] The core of the present invention is to provide a test tube righting and rotating device, which can reduce the probability of misalignment when the pressure head contacts the target test tube 2. Another core of the present invention is to provide a medical analyzer including the test tube righting and rotating device.

[0054] Please refer to Figure 1-7 , Figure 1 This is an exploded schematic diagram of a specific embodiment of the test tube righting and rotating device provided by the present invention; Figure 2 for Figure 1 Axonometric diagram of the test tube righting and rotating device; Figure 3 for Figure 1 Axonometric diagram of the test tube righting and rotating device from another observation angle; Figure 4 for Figure 1 Schematic top view of the test tube righting and rotating device; Figure 5 for Figure 1 Exploded diagram of the central righting mechanism and linkage connector; Figure 6 is a structural diagram of the sliding plate; Figure 7 Schematic diagram of the structure of the mounting plate.

[0055] This specific embodiment provides a test tube righting and rotating device, including: a driving mechanism, a lifting mechanism, a rotating mechanism 1, a righting mechanism 3, a fixing mechanism and a linkage connector; the lifting mechanism is arranged on the fixing mechanism and can rise or fall relative to the fixing mechanism; the rotating mechanism 1 is arranged on the lifting mechanism and rises or falls with the lifting mechanism; the driving mechanism drives the lifting mechanism to rise and fall and drives the rotating mechanism 1 to rotate; the linkage connector connects the fixing mechanism, the righting mechanism 3 and the lifting mechanism to enable the righting mechanism 3 to move in linkage with the lifting mechanism; when the lifting mechanism descends, the righting mechanism 3 approaches and contacts the target test tube 2 from the side to limit the position of the target test tube 2, and the rotating mechanism 1 approaches and contacts the target test tube 2 from the top to rotate the target test tube 2; when the lifting mechanism rises, the righting mechanism 3 and the rotating mechanism 1 are separated from the target test tube 2.

[0056] It should be noted that the straightening mechanism 3 straightens the test tube from the side, which can be done by friction, or by moving the target test tube 2 to the straightening position through a mold that matches the outer dimensions of the test tube. The specific method is determined according to actual conditions and will not be elaborated here.

[0057] During use, the lifting mechanism and the rotation of the rotating mechanism 1 can be controlled by controlling the action of the driving mechanism, and because the righting mechanism 3 is connected to the lifting mechanism through a linkage connection, the lifting mechanism can be controlled to drive the rotating mechanism 1 to move downward. At this time, the righting mechanism 3 moves in the direction close to the target test tube 2 until the test tube is righted; if the rotating mechanism 1 has not yet contacted the target test tube 2 at this time, the lifting mechanism needs to drive the rotating mechanism 1 to continue moving downward until the rotating mechanism 1 contacts the target test tube 2; after the rotating mechanism 1 contacts the target test tube 2, it can drive the target test tube 2 to rotate through friction; after the rotation is completed, the lifting mechanism drives the rotating mechanism 1 to rise, and the righting mechanism 3 moves in the direction away from the target test tube 2 under the action of the linkage connection until it is restored to its initial position.

[0058] It should be noted that after the righting mechanism 3 rightes the target test tube 2, if the rotating mechanism 1 has not yet contacted the target test tube 2, the lifting mechanism needs to drive the rotating mechanism 1 to continue moving downward until the rotating mechanism 1 contacts the target test tube 2; preferably, when the righting mechanism 3 rightes the target test tube 2, the rotating mechanism 1 just contacts the target test tube 2.

[0059] Compared with the prior art, the test tube straightening and rotating device provided in this specific embodiment can straighten the test tube before rotating the test tube, reduce the probability of random deflection of the target test tube 2, and align the pressure head 11 of the rotating mechanism 1 with the central axis of the target test tube 2. In addition, the straightening mechanism 3 straightens the test tube from the side, so that a certain gap can be created between the target test tube 2 and the adjacent test tubes, avoiding contact between the rotating mechanism 1 and the adjacent test tubes of the target test tube 2.

[0060] On the basis of the above embodiment, in order to detect whether the target test tube 2 exists, a detection mechanism for detecting whether the target test tube 2 exists at the processing station may be further included.

[0061] Preferably, the detection mechanism is a through-beam sensor.

[0062] The through-beam sensor can be set on the lifting mechanism or on the righting mechanism 3. When the rotating mechanism 1 moves downward, after the rotating mechanism 1 moves a certain distance, the through-beam sensor will determine whether the rotating mechanism 1 has moved to a certain position. The through-beam sensor transmits the received signal to the control mechanism. The control mechanism controls the rotating mechanism 1 to stop moving or controls the rotating mechanism 1 to rise to the initial position according to the received information.

[0063] The control mechanism mentioned in this specific embodiment is a structure for processing information from the through-beam sensor, and can also control the action of the driving mechanism.

[0064] Preferably, the detection mechanism is a non-contact sensor, or a pressure sensing structure installed in the rotating mechanism 1 .

[0065] like Figure 1 As shown, by cooperating with the light baffle 81 and the optical coupler, detection of whether the target test tube 2 exists at the processing station is achieved. When the light baffle 81 is at the height of the upper optical coupler 82, the upper optical coupler 82 detects the height position information of the lifting mechanism. When the light baffle 81 is at the height of the lower optical coupler 83, the lower optical coupler 83 detects the height position information of the lifting mechanism.

[0066] On the basis of the above embodiment, in order to realize linkage between the rotating mechanism 1 and the straightening mechanism 3, the linkage connection member may include a sliding plate 51 for mounting the straightening mechanism 3, and the sliding plate 51 is arranged on the fixing mechanism through a sliding connection member 52;

[0067] The sliding plate 51 is provided with a guide groove 511 , and the lifting mechanism is provided with a sliding portion 64 that slides along the guide groove 511 when the lifting mechanism moves;

[0068] When the lifting mechanism moves, the sliding portion 64 drives the sliding plate 51 to slide through the sliding connector 52 , so that the sliding plate 51 moves closer to or away from the target test tube 2 .

[0069] like Figure 4 As shown, preferably, the sliding plate 51 is a plate-like structure with a bend.

[0070] Preferably, the sliding portion 64 can be configured as a rotating shaft or a bearing.

[0071] The sliding connection member 52 includes a linear guide rail 522 and a linear slider 521 . The linear guide rail 522 is fixed to the fixing mechanism. The linear slider 521 is disposed on the linear guide rail 522 and connected to the sliding plate 51 .

[0072] On the basis of the above embodiment, the guide groove 511 may include a linkage section 5111 arranged in an inclined or arc shape;

[0073] When the sliding portion 64 is located at the linkage section 5111 , the righting mechanism 3 moves away from the target test tube 2 when the lifting mechanism rises, and the righting mechanism 3 moves closer to the target test tube 2 when the lifting mechanism descends.

[0074] In order to enable the lifting mechanism to be able to rise and fall independently without being linked with the straightening mechanism 3, the guide groove 511 may further include a non-linked section 5112;

[0075] When the sliding portion 64 is located in the non-linkage section 5112 and the lifting mechanism rises or falls, the straightening mechanism 3 remains stationary or moves in the vertical direction.

[0076] like Figure 4 、 Figure 5As shown, the guide groove 511 includes a vertically arranged non-linkage section 5112 and an inclined linkage section 5111. Preferably, the inclination angle of the linkage section 5111 is 45°. Of course, it can also be set to other inclination angles, which are determined according to actual conditions and will not be elaborated here.

[0077] When the linkage section 5111 of the guide groove 511 is an inclined straight section, during the linkage process of the righting mechanism 3 , if the rising speed of the rotating mechanism 1 is uniform, the moving speed of the righting mechanism 3 is also uniform.

[0078] Of course, the linkage section 5111 can also be in other shapes besides being inclined or arc-shaped, which is determined according to actual conditions and only needs to meet the linkage requirements.

[0079] On the basis of the above embodiment, the righting mechanism 3 may include a first roller 31 and a second roller 32 for righting the target test tube 2 and a mounting member 33 for mounting the first roller 31 and the second roller 32;

[0080] The first roller 31 and the second roller 32 are located at the same height and spaced apart; and the axial direction of the first roller 31 and the axial direction of the second roller 32 are both arranged along the vertical direction.

[0081] Preferably, the first roller 31 and the second roller 32 are both arranged on the rivet column and are both fixed by an E-shaped retaining spring 34 .

[0082] In order to adapt to test tubes of different sizes, a slide groove for installing the first roller 31 and the second roller 32 can be set on the mounting member 33, and the first roller 31 and the second roller 32 can be slidably set in the slide groove; during use, the positions of the first roller 31 and the second roller 32 can be adjusted to adapt to test tubes of different sizes.

[0083] In addition, a U-shaped groove 331 for the target test tube 2 to enter may be provided on the mounting member 33 , and the first roller 31 and the second roller 32 are slidably provided on two arms of the U-shaped groove 331 .

[0084] like Figure 4 As shown, one end of the sliding plate 51 is provided with a horizontal bend, and this bend is a mounting member 33. The mounting member 33 is provided with a U-shaped groove 331. In the process of straightening the target test tube 2, the target test tube 2 enters through the U-shaped groove 331. The first roller 31 and the second roller 32 provided on both sides thereof are collectively referred to as rollers. Under the action of the rollers, the target test tube 2 is limited in the left and right directions. Then, as the sliding plate 51 moves, when the bottom of the U-shaped groove 331 contacts the target test tube 2, the target test tube 2 can be limited in the front and rear directions, so that the target test tube 2 can be straightened.

[0085] When the rotating mechanism 1 drives the test tube to rotate, the roller can rotate together with the test tube. Since the contact area between the roller and the test tube is very small, the friction between the roller and the test tube is not enough to affect the rotation of the test tube.

[0086] On the basis of the above embodiment, the rotating mechanism 1 includes a pressing head 11 that drives the target test tube 2 to rotate through friction.

[0087] In order to increase the friction between the indenter 11 and the target test tube 2 , the indenter 11 can be made of polyurethane or rubber. Of course, it can also be made of other materials that can increase friction.

[0088] On the basis of the above embodiment, the lifting mechanism may include a power plate 61 driven by a driving mechanism to lift and lower, and a mounting plate 62 for mounting the rotating mechanism 1, wherein the mounting plate 62 is stacked on the upper portion of the power plate 61;

[0089] The fixing mechanism is provided with a tension spring 63 for providing power for the mounting plate 62 to move downward. One end of the tension spring 63 is connected to the fixing mechanism, and the other end is connected to the mounting plate 62.

[0090] During use, the driving mechanism can drive the power plate 61 to rise and fall. When the power plate 61 rises, it will push the mounting plate 62 to rise. When the power plate 61 falls, the tension spring 63 will cause the mounting plate 62 to fall to its initial position.

[0091] Preferably, in order to limit the rising distance of the mounting plate 62 , a stopper 65 may be provided.

[0092] On the basis of the above embodiment, the driving mechanism may include a rotating motor 72 for driving the rotating mechanism 1 to rotate, a first transmission device for transmitting the power of the rotating motor 72 to the rotating mechanism 1, a lifting motor for driving the lifting mechanism to lift, and a second transmission device for transmitting the power of the lifting motor to the lifting mechanism;

[0093] The lifting motor and the second transmission device are both installed on the fixing mechanism, and the rotating motor 72 and the first transmission device are both installed on the lifting mechanism.

[0094] Preferably, the first transmission device includes a conveyor belt 73 wrapped around the output end 74 of the rotating motor 72 and a power wheel 78 for driving the rotating mechanism 1 to rotate. The conveyor belt 73 is wrapped around the circumference of the power wheel 78 to drive the power wheel 78 to rotate.

[0095] Preferably, the second transmission device includes a screw rod 79 driven to rotate by the lifting motor and a screw rod nut 75 matched with the screw rod 79; the screw rod nut 75 is connected to the lifting mechanism.

[0096] The first transmission device further includes two idler gears 77 for transmitting power.

[0097] The rotating motor 72 and the transmission mechanism are both mounted on the rotating mounting plate 62 .

[0098] On the basis of the above embodiment, the driving device may include a dual-output shaft motor installed on the lifting mechanism, one end of the dual-output shaft motor is connected to the rotating mechanism 1 to drive the rotating mechanism 1 to rotate;

[0099] The other end of the dual-output shaft motor is connected to the fixing mechanism to drive the lifting mechanism to move up and down.

[0100] Preferably, the rotating motor 72 drives the target test tube 2 to rotate through a synchronous belt drive, and the screw nut 75 is connected to the vertical guide rail pair through friction. When overload, slippage, and power failure occur, the rotating mechanism 1 is separated from the target test tube 2 by a spring.

[0101] The lifting mechanism includes a lifting motor, a motor fixing seat 4, a screw rod 79 connected to the output end of the lifting motor, a screw nut 75 and a power plate 61 connected to the screw nut 75; the lifting motor is arranged on the motor fixing seat 4, preferably, the lifting motor is a screw motor 71, the output end of the screw motor 71 cooperates with the screw nut 75, and the linear guide rail 522 of the sliding connection 52 is fixedly arranged on the motor fixing seat 4.

[0102] The screw motor 71 rotates under the control of the control mechanism and can move the power plate 61 upward or downward through transmission with the screw nut 75 .

[0103] On the basis of the above embodiment, a light rod 76 for guidance can be set on the motor fixing seat 4, the power plate 61 is provided with a first through hole 611 for cooperating with the light rod 76, the mounting plate 62 is provided with a second through hole 621 for cooperating with the light rod 76, and the mounting plate 62 is provided on the upper part of the power plate 61 so that the power plate 61 drives the mounting plate 62 to move upward.

[0104] When the rotating mechanism 1 needs to move downward, a tension spring 63 can be provided on the motor fixing seat 4, one end of the tension spring 63 is connected to the motor fixing seat 4, and the other end is connected to the mounting plate 62; Figure 1 As shown, one end of the tension spring 63 is connected to the motor fixing seat 4, and the other end is connected to the mounting plate 62. When it needs to move downward, the screw motor 71 rotates in the opposite direction, and the mounting plate 62 moves downward along the light rod 76 under the action of the tension of the tension spring 63 and its own gravity.

[0105] In order to reduce the friction between the optical rod 76 and the first through hole 611 and the second through hole 621, a shaft sleeve can be provided on the outer periphery of the optical rod 76; preferably, the optical rod 76 includes a first optical rod and a second optical rod, and the number of the first through holes 611 is two, one of which cooperates with the first optical rod and the other cooperates with the second optical rod, and the number of the second through holes 621 is also two, one of which cooperates with the first optical rod and the other cooperates with the second optical rod.
