Description

Technical Field

[0001] This utility model relates to an automated vertical motion mechanism for a coagulation analyzer, belonging to the field of automated vertical motion mechanisms for coagulation analyzers. Background Technology

[0002] A coagulation analyzer is used clinically to measure the levels of various components in human blood, providing quantitative biochemical analysis results. It helps doctors diagnose bleeding disorders, such as coagulation factor deficiencies and platelet dysfunction, and provides patients with effective treatment plans. The main components include a sample delivery system, a detection system, a control system, a data processing system, a display and printing system, a communication system, a power supply system, a cooling system, and a reagent storage system. The sample delivery system is the only moving part of the coagulation analyzer; the others are static. Automating its stable operation would significantly reduce manual labor. Utility Model Content

[0003] To overcome the above-mentioned shortcomings, the purpose of this utility model is to provide an automated vertical motion mechanism for a coagulation analyzer, thereby reducing manual labor.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an automated vertical motion mechanism for a coagulation analyzer, comprising a base plate, a side plate, a top plate, a pair of slide rods, a slider, a support plate, a connecting plate, and a stepper motor. The two ends of the side plate are vertically connected to the ends of the base plate and the top plate, respectively. The pair of slide rods are fixedly connected parallel to each other between the top plate and the base plate, and the slider is slidably connected on the slide rods. The stepper motor is connected to the side plate. One end of the support plate is fixedly connected to the connecting plate.

[0005] The output shaft of the stepper motor is connected to a drive wheel, the top of the side plate is connected to a rotating shaft, a driven wheel is rotatably connected to the rotating shaft, and a ring-shaped synchronous belt is sleeved between the driven wheel and the drive wheel. The slider is fixedly connected to the synchronous belt at one point through the connecting plate. A position switch is provided on the top of the side plate. When the position switch detects the support plate, it stops supplying power to the stepper motor.

[0006] The present invention is further configured such that: a zero-position optocoupler is provided on the base plate, and the zero-position optocoupler is located on the side of the connecting plate for detecting whether the connecting plate is at the zero point position.

[0007] A further feature of this invention is that a limiting plate is provided at the edge of the tray, and the limiting plate abuts against the top plate after moving upward.

[0008] A further feature of this invention is that a baffle is provided on the edge of the tray, and the baffle is perpendicular to the limiting plate.

[0009] A further feature of this invention is that the height of the baffle is less than the height of the limiting plate.

[0010] The present invention is further configured such that: each of the sliding rods has two sliders, and both pairs of sliders are connected to the connecting plate.

[0011] The present invention is further configured such that: the connecting plate includes a first connecting plate and a second connecting plate, the first connecting plate is connected to the slider on any one of the sliding rods, one end of the second connecting plate is connected to the middle of the first connecting plate, and the other end is connected to the support plate.

[0012] Compared with existing technologies, the advantages of this invention are as follows: Starting the stepper motor drives the driving wheel to rotate, causing the synchronous belt between the driving and driven wheels to rotate. A connecting plate fixedly connected to a point on the synchronous belt drives the support plate to move. Since the slider slides on the slide rod, it guides the moving support plate, guiding it to move vertically upwards. Once the support plate approaches the position switch, the position switch detects the approach and sends a stop signal. The stepper motor is then de-energized, and the support plate and slider, relying on gravity, cause the slider to slide down the slide rail until it returns to its initial position and stops moving.

[0017] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0018] See appendix Figure 1-3As shown, an automated vertical motion mechanism for a coagulation analyzer in this embodiment includes a base plate 1, a side plate 2, a top plate 3, a pair of slide rods 8, a slider 9, a support plate 14, a connecting plate, and a stepper motor 4. The two ends of the side plate 2 are vertically connected to the ends of the base plate 1 and the top plate 3, respectively. The pair of slide rods 8 are fixedly connected parallel to each other between the top plate 3 and the base plate 1. The slider 9 is slidably connected to the slide rods 8. The stepper motor 4 is connected to the side plate 2. The support plate 14 is fixedly connected to one end of the connecting plate.

[0019] The output shaft of the stepper motor 4 is connected to a drive wheel 5, the top of the side plate 2 is connected to a rotating shaft 7, a driven wheel 6 is rotatably connected to the rotating shaft 7, and an annular synchronous belt 16 is sleeved between the driven wheel 6 and the drive wheel 5. The slider 9 is fixedly connected to the synchronous belt 16 at one point through the connecting plate. A position switch 15 is provided on the top of the side plate 2. The position switch 15 stops supplying power to the stepper motor 4 after detecting the support plate 14.

[0020] The stepper motor 4 is started, driving the drive wheel 5 to rotate. The synchronous belt 16 between the drive wheel 5 and the driven wheel 6 rotates, and the connecting plate fixedly connected to a point on the synchronous belt 16 drives the support plate 14 to move. Since the slider 9 slides on the slide rod 8, it guides the moving support plate 14, guiding it to move vertically upward. Until the support plate 14 approaches the position switch 15, the position switch 15 detects the approach of the support plate 14 and sends a stop signal. The stepper motor 4 is de-energized, and the support plate 14 and the slider 9 rely on gravity. The slider 9 slides down the slide rail until it returns to the initial position and stops moving.

[0021] To detect whether the pallet 14 has returned to its initial position, this invention further includes a zero-position optocoupler 11 on the base plate 1. The zero-position optocoupler 11 is located on the side of the connecting plate and is used to detect whether the connecting plate is at the zero point position. When the connecting plate is at the zero point position, the pallet 14 is also at the zero point position. This ensures that the next upward movement of the pallet 14 accurately reaches the designated height. Preferably, the stepper motor 4 is electrically connected to a power module, the power module is electrically connected to a controller, and the controller is electrically connected to the position switch 15 and the zero-position optocoupler 11.

[0022] To prevent excessive movement of the pallet 14, this invention further includes a limiting plate 12 at the edge of the pallet 14. The limiting plate 12, after moving upwards, abuts against the top plate 3, preventing further upward movement and thus avoiding overturning due to excessive upward movement of the pallet 14.

[0023] To prevent the sample to be tested carried on the tray 14 from slipping off, the present invention further includes a baffle 13 on the edge of the tray 14, which is perpendicular to the limiting plate 12. The baffle 13 prevents the sample from crossing the edge of the tray 14, thus restricting the position of the sample and preventing it from slipping off the tray 14.

[0024] To avoid interference between the baffle 13 and the driven wheel 6, this invention is further configured such that the height of the baffle 13 is less than the height of the limiting plate 12. Since the limiting plate 12 is higher, it contacts the top plate 3 first, thus preventing the support plate 14 from moving further upward.

[0025] To enhance the operational stability of the slider 9, connecting plate, and support plate 14, this invention further comprises: two sliders 9 on any one of the sliding rods 8, and each pair of sliders 9 is connected to the connecting plate. The more sliders 9 there are, the better the operational stability of the sliders 9, connecting plate, and support plate 14.

[0026] The present invention is further configured such that: the connecting plate includes a first connecting plate 10 and a second connecting plate 17; the first connecting plate 10 is connected to the slider 9 on any of the sliding rods 8; one end of the second connecting plate 17 is connected to the middle of the first connecting plate 10, and the other end is connected to the support plate 14. Overall, the connecting plate composed of the first connecting plate 10 and the second connecting plate 17 has a T-shaped structure. To save materials, preferably, a through hole 18 is provided in the middle of the support plate 14.

[0027] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They cannot be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
