Description

Technical Field

[0001] The utility model relates to an image acquisition system for a lipoprotein analyzer. Background Art

[0002] Lipoprotein subtype testing utilizes polyacrylamide gel electrophoresis, a diagnostic method for lipoprotein subfraction classification. Polyacrylamide gel electrophoresis separates lipoprotein subtypes based on particle size and charge. Within a given timeframe, lipoproteins can be divided into 12 subtypes (low-density lipoprotein cholesterol types 1-7, intermediate-density lipoprotein cholesterol types ABC, very-low-density lipoprotein cholesterol, and low-density lipoprotein), each of which is concentrated in a specific location, forming a tight pulsating band. The sample tube obtained after electrophoresis is then placed in an existing biological sample analysis device, where an image acquisition system captures the sample image, and the image analysis system then draws a diagnostic conclusion.

[0003] During their research, the inventors discovered that the imaging equipment of existing biological sample analyzers is installed inside the device, near the top, and the camera of the imaging equipment is exposed to the inside of the device. Consequently, dust that enters the device tends to adhere to the camera's mirror surface, making it difficult to clean, affecting the camera's image quality and causing a decrease in captured image quality. Therefore, to address these shortcomings of the existing technology, they developed a lipoprotein analyzer image acquisition system that protects the camera from dust. Utility Model Content

The two components are sealed and connected by a sealing ring; a light source controller, which is installed on one side of the dust cover; a surface light source, which is installed below the notch and is electrically connected to the light source controller; a tray, which is slidably installed on the tray bracket and is located above the surface light source, and the lipoprotein analyzer is provided with an inlet and outlet corresponding to the tray; a sample rack, which is provided with multiple pipe slots and is installed on the tray; and a tray driving mechanism, which is installed in the lipoprotein analyzer and is transmission-connected to the tray; wherein the industrial camera, the surface light source, and the tray driving mechanism are all electrically connected to the industrial control screen.

[0007] Furthermore, the lipoprotein analyzer image acquisition system of the present invention further includes a sealing gasket, and the upper transparent dustproof member, the dustproof cover and the top surface of the tray bracket are all tightly connected via the sealing gasket.

[0008] Furthermore, the tray drive mechanism includes a guide rail, on which a slider is slidably mounted, and the slider is transmission-connected to the tray; a lead screw, which is spaced and parallel to the guide rail, with a slider extending through one end to be rotatably connected to the base, and the other end being transmission-connected to the tray drive member; a baffle, which is mounted on the slider; a motor driver; a first photoelectric sensor, which is mounted near one end of the guide rail; and a second photoelectric sensor, which is mounted near the other end of the guide rail; wherein the first photoelectric sensor, the second photoelectric sensor, and the tray drive member are all electrically connected to the motor driver; the motor driver is electrically connected to the industrial control panel; the lead screw is transmission-connected to the slider, and the slider drives the baffle to move toward the first photoelectric sensor and the second photoelectric sensor to trigger photoelectric sensing.

[0009] Furthermore, the utility model provides a lipoprotein analyzer image acquisition system further comprising a connector, wherein a slide groove is provided on the tray bracket along the extension direction of the guide rail, one end of the connector is connected to the slider, and the other end passes through the slide groove and is connected to the tray.

[0010] Furthermore, the utility model provides an image acquisition system for a lipoprotein analyzer, which also includes a traveling wheel, a rotating wheel and a guide plate; the rotating wheels are installed on both sides of one end of the tray bracket; one end of the tray is overlapped with the rotating wheel, and the traveling wheels are installed on both sides of the other end; a guide plate is installed on each of the two traveling wheels on the tray bracket, and the guide plate supports the traveling wheel to rotate along the extension direction of the guide rail.

[0011] Furthermore, the slider and the lead screw are threadedly connected.

[0012] Furthermore, the first photoelectric sensor is a PNP photoelectric gate or an NPN photoelectric gate; the second photoelectric sensor is a PNP photoelectric gate or an NPN photoelectric gate.

[0013] Furthermore, the lipoprotein analyzer image acquisition system of the present invention further includes lifting ears, and the lifting ears are installed at both ends of the sample rack.

[0014] Furthermore, an arc groove is provided on the tray corresponding to the lifting lug.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. This utility model provides a closed, dust-proof space for the lens of an industrial camera. Specifically, one end of the dust cover is tightly connected to the lens via a sealing ring, while the other end is pressed against a transparent dust cover that snaps onto the notch of the tray holder. The airtight connection between the dust cover and the tray holder creates a sealed, clean working environment for the lens, effectively preventing dust from entering and improving image quality. The transparent dust cover allows the lens to see through it while shooting, capturing images of sample tubes on the sample rack.

[0017] 2. The present invention also overcomes the problem of manually driving the tray. It utilizes a tray entry and exit mechanism to drive the tray, allowing it to enter and exit the lipoprotein analyzer without requiring personnel to push the tray. Specifically, the industrial control screen controls the operation of the tray driver, which drives the lead screw to rotate. The lead screw in turn drives the slider, which in turn moves the baffle and the tray. When the slider moves toward the second photoelectric sensor, the tray extends and moves out of the lipoprotein analyzer. When the baffle triggers the second photoelectric sensor, the tray driver pauses, and the lead screw, slider, baffle, and tray stop moving. At this point, the tray extends out of the lipoprotein analyzer, and the sample rack on the tray is located outside the lipoprotein analyzer.

[0018] When the industrial control screen controls the tray drive to reverse the lead screw, the slider, baffle, and tray move toward the first photoelectric sensor, and the tray is then stored inside the lipoprotein analyzer. When the baffle triggers the first photoelectric sensor, the tray drive stops, and the lead screw, slider, baffle, and tray all stop moving. The sample rack on the tray is now positioned beneath the upper transparent dust shield. This indicates that the interaction between the first and second photoelectric sensors and the baffle limits the movement of the tray. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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.

[0030] Example 1:

[0031] like Figures 1 to 4 As shown, a lipoprotein analyzer image acquisition system includes an industrial control screen 20, a tray holder 13, an upper transparent dustproof member 8, a dust cover 5, an industrial camera 1, light source controllers 17 and 15, a tray 11, a sample rack 10, and a tray drive mechanism 12. The industrial control screen 20 is mounted on the lipoprotein analyzer 19 and is equipped with an image acquisition module 201 and a machine learning image analysis module 202. The tray holder 13 is mounted within the lipoprotein analyzer 19 and has a notch 131 extending through its top surface. The upper transparent dustproof member 8 is fastened to the top surface of the notch 131. The bottom of the dust cover 5 presses against the upper transparent dustproof member 8 to securely attach to the top surface of the tray holder 13. The industrial camera 1 is equipped with a lens 4, which is mounted on top of the dust cover 5. The lens 4 is inserted into the dust cover 5 and is sealed to the dust cover 5 via a sealing ring 6. The light source controller 17 is located on a side of the dust cover 5. The surface light source 15 is mounted below the slot 131 and is electrically connected to the light source controller. Slidingly mounted on the tray bracket 13 and positioned above the surface light source 15, the lipoprotein analyzer 19 has an inlet and outlet 191 corresponding to the tray 11. The sample rack 10 has multiple slots 102 formed therein and is mounted on the tray 11. The tray drive mechanism 12 is mounted within the lipoprotein analyzer 19 and is in transmission connection with the tray 11. The industrial camera 1, light source controller 17, and tray drive mechanism 12 are all electrically connected to the industrial control panel 20.

[0032] Multiple tube slots 102 are spaced and arranged in parallel along the length of the sample rack 10. The number of tube slots can be 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, or 30, etc. An appropriate number of tube slots can be selected based on the specifications of the sample rack. It is understood that the width of the tube slots is smaller than the diameter of the sample tube, allowing the sample tube to be placed horizontally in the tube slots.

[0033] It can be understood that the top and bottom of the tube groove are both open.

[0034] An industrial camera and dust cover mounting structure includes an industrial camera mount 2 and an adjustment plate 3. The industrial camera mount 2 is mounted on the adjustment plate 3, which is mounted on the dust cover 5. The adjustment plate 3 is used to adjust the position of the industrial camera to achieve the optimal shooting state.

[0035] The light source controller 17 can be used to adjust the brightness of the surface light source. The light source controller 17 is electrically connected to the industrial control panel 20. The industrial control panel 20 can be used to control the light source controller 17 and further control the surface light source 15.

[0036] In order to further improve the dustproof effect of the dustproof cover, a sealing gasket 9 is additionally installed, and the upper transparent dustproof part 8, the dustproof cover 5 and the top surface of the tray bracket 13 are all sealed and connected via the sealing gasket 9.

[0037] like Figure 1 and 2 As shown, the bottom of the light source 18 is mounted on the bottom plate 16 with the gap 131 between them. The lower transparent dustproof member 14 is mounted on the bottom of the tray 11 and is located below the sample rack 10 to protect the surface light source 15 from being clean.

[0038] It is understandable that a bracket for mounting the sample rack is provided on the tray, and a lower transparent dustproof member 14 is installed at the bottom of the bracket. When the sample rack is installed, the sample rack overlaps the top surface of the bracket.

[0039] The front end of the lipoprotein analyzer 19 is provided with an inlet and outlet 191. A tray drive mechanism drives the tray to extend outward through the inlet and outlet, allowing the tray to be removed from the lipoprotein analyzer 19 and placed into the sample rack on the tray. After the sample tube is installed, the tray drive mechanism drives the tray through the inlet and outward and stores it within the lipoprotein analyzer 19.

[0040] It should be noted that when the tray is located on the lipoprotein analyzer 19 , the sample rack on the tray is located below the notch 131 and the upper transparent dustproof member 8 .

[0041] It should also be noted that when it is necessary to clean the bottom surface of the upper transparent dustproof part, a cleaning cloth can be stacked on the sample rack. The cleaning cloth can be stacked in multiple layers and placed on the sample rack as needed. The stacked height of the cleaning cloth is slightly higher than the top surface of the tray. Then, by driving the tray in and out relative to the lipoprotein analyzer 19, the tray drives the cleaning cloth to scrub the bottom surface of the upper transparent dustproof part, thereby cleaning the bottom surface of the upper transparent dustproof part and removing the dust adsorbed on the bottom surface of the upper transparent dustproof part.

[0042] like Figure 2As shown, a structure of a tray drive mechanism is provided. The tray drive mechanism 12 includes a guide rail 129, a lead screw 1211, a baffle 124, a motor driver 123, a first photoelectric sensor 125, and a second photoelectric sensor 127. A slider 1212 is slidably mounted on the guide rail 129, and the slider 1212 is transmission-connected to the tray 11. The lead screw 1211 is spaced parallel to the guide rail 129. One end of the lead screw 1211 passes through the slider 1212 and extends to be rotationally connected to the base 128, while the other end is transmission-connected to the tray drive 122. The baffle 124 is mounted on the slider 1212. The first photoelectric sensor 125 is mounted near one end of the guide rail 129. The second photoelectric sensor 127 is mounted near the other end of the guide rail 129. The first photoelectric sensor 125, the second photoelectric sensor 127, and the tray drive 122 are all electrically connected to the motor driver 123, which is in turn electrically connected to the industrial control panel 20. The lead screw 1211 is in transmission connection with the slider 1212 , and the slider 1212 drives the blocking piece 124 to move toward the first photoelectric sensor 125 and the second photoelectric sensor 127 to trigger photoelectric sensing.

[0043] It is understandable that the industrial control panel can control the operation of the tray drive 122 through the motor driver 123, so that the tray drive can change the rotation direction, speed, start and stop of the screw.

[0044] One configuration of the tray drive 122 may be a leadscrew drive motor.

[0045] like Figure 2 As shown in FIG, a mounting structure of a photoelectric sensor is provided, in which a photoelectric gate bracket 126 is additionally mounted. The first photoelectric sensor 125 and the second photoelectric sensor 127 are respectively mounted on a guide rail 129 through a photoelectric gate bracket 126 .

[0046] The first photoelectric sensor 125 is used to position the tray when it moves into the lipoprotein analyzer 19. When the baffle 124 triggers the first photoelectric sensor 125, the first photoelectric sensor 125 sends a data signal to the motor driver 123. After receiving the data signal, the motor driver 123 controls the tray drive 122 to stop working, and the tray drive mechanism 12 stops driving the tray to move. At this time, the sample rack 10 on the tray 11 is located directly below the notch 131 of the tray support 13.

[0047] Second photoelectric sensor 127 is used to position the tray as it extends beyond lipoprotein analyzer 19. When flap 124 triggers second photoelectric sensor 127, it sends a data signal to motor driver 123. Upon receiving this signal, motor driver 123 controls tray driver 122 to stop, and the tray drive mechanism stops driving the tray. At this point, the majority of the tray has extended beyond lipoprotein analyzer 19, and sample rack 10 on tray 11 is positioned outside lipoprotein analyzer 19, allowing sample tubes to be loaded flat onto the rack. Once sample tubes are loaded, the industrial control panel controls the tray drive mechanism again, driving the tray toward lipoprotein analyzer 19 for storage. When flap 124 triggers first photoelectric sensor 125, motor driver 123 controls tray driver 122 to stop, and the tray drive mechanism stops driving the tray.

[0048] It is understood that the surface light source 15 is located below the tray and does not hinder the tray's movement. When needed, the light source can be turned on to illuminate the sample rack, increasing brightness and facilitating the industrial camera's lens to capture the multiple sample tubes on the rack. The captured images are then transmitted by the industrial camera to the industrial control screen 20. The image acquisition module 201 on the industrial control screen 20 captures the images, allowing biological sample information to be entered and collected. The machine learning image analysis module on the industrial control screen analyzes the images captured by the image acquisition module 201 and derives the analysis results, thereby enabling rapid health diagnosis.

[0049] In some optional embodiments, a connecting member 121 is additionally installed, and a slide groove 1210 is provided on the tray bracket 13 along the extension direction of the guide rail 129. One end of the connecting member 121 is connected to the slider 1212, and the other end passes through the slide groove 1210 and is connected to the tray 11.

[0050] It is understandable that when the connecting member 121 moves toward the first photoelectric sensor 125 and the second photoelectric sensor 127 , the sliding groove 1210 does not restrict the movement of the connecting member 121 .

[0051] In some optional embodiments, a traveling wheel 21, a rotating wheel 18 and a guide plate are additionally installed; the rotating wheels 18 are installed on both sides of one end of the tray bracket 13; one end of the tray 11 is overlapped with the rotating wheel 18, and the traveling wheels 21 are installed on both sides of the other end; a guide plate is installed on each of the two traveling wheels 21 on the tray bracket 13, and the guide plate supports the traveling wheel 21 to rotate along the extension direction of the guide rail 129.

[0052] In some optional embodiments, a connection method between the slider and the lead screw is provided: the slider 1212 and the lead screw 1211 are threadedly connected.

[0053] In some optional embodiments, the structural type of the photoelectric sensor is given.

[0054] The first photoelectric sensor 125 is a PNP photoelectric gate or an NPN photoelectric gate; the second photoelectric sensor 127 is a PNP photoelectric gate or an NPN photoelectric gate.

[0055] The first type is: the first photoelectric sensor 125 is a PNP photoelectric gate; the second photoelectric sensor 127 is an NPN photoelectric gate.

[0056] The second type is: the first photoelectric sensor 125 is a PNP photoelectric gate; the second photoelectric sensor 127 is a PNP photoelectric gate.

[0057] The third type is: the first photoelectric sensor 125 is an NPN photoelectric gate; the second photoelectric sensor 127 is an NPN photoelectric gate.

[0058] In some optional embodiments, in order to facilitate the installation of the sample rack on the tray, additional lifting ears 101 are installed. Lifting ears 101 are installed at both ends of the sample rack 10. The inspector can hold a lifting ear with both hands to lift the sample rack as a whole.

[0059] In some optional embodiments, in order to reduce the obstruction of the hand-held lifting ears of the inspectors, the tray 11 is provided with an arc groove 111 corresponding to the lifting ears 101. The arc groove 111 is concave downward along the height direction of the tray, increasing the space and reducing the impact of the tray on the hand-held lifting ears.

[0060] The above embodiments are preferred implementation methods of the present invention and are only used to facilitate the explanation of the present invention. They are not intended to limit the present invention in any form. Any person with ordinary knowledge in the technical field can, without departing from the scope of the technical features of the present invention, make partial changes or modifications to the technical contents disclosed in the present invention and make equivalent embodiments without departing from the technical features of the present invention. These modifications still fall within the scope of the technical features of the present invention.
