Description

Technical Field

[0001] The present disclosure relates to the field of biomedical instruments, and in particular to a reagent kit assembly device for a blood cell analyzer. Background Art

[0002] The blood cell analyzer, also known as the blood cell analyzer, blood cell meter, blood cell counter, etc., is one of the instruments widely used in clinical tests in hospitals. Existing POCT blood cell analyzers usually need to be equipped with a sealing ring, a microporous sheet and a back pool in the cavity of the test kit, such as a test kit disclosed in the Chinese patent application number CN202121839169.8, and a test kit and a POCT blood cell analyzer disclosed in the Chinese patent application number CN202110839658.1. The sealing ring is used to ensure the sealing between the components and prevent liquid or gas leakage. The microporous sheet is provided with tiny holes (micropores), and the micropores are used for blood cells to pass through one by one for counting and analysis. The back pool is a component for receiving and processing blood cells passing through the microporous sheet.

[0003] However, when assembling a POCT blood cell analyzer, the sealing ring, microporous sheet and back pool are generally assembled by semi-automatic equipment, that is, after the sealing ring is installed in the cavity, the microporous sheet with micropores is manually screened and installed in the cavity in a predetermined direction, and finally the back pool cover is placed on the reagent box port. Since each microporous sheet needs to be screened manually, there is a problem of low efficiency. Moreover, since the diameter of the micropores is very small, it is difficult to accurately distinguish whether there are holes with the naked eye. If a microporous sheet without holes is placed in the cavity, the entire POCT blood cell analyzer will be scrapped, so there is a problem of low yield rate.

[0004] Therefore, there is an urgent need for an assembly equipment with a high degree of automation to achieve higher production efficiency and yield rate. Summary of the invention

[0035] The present disclosure provides a reagent kit assembly device for a blood cell analyzer, comprising a conveyor frame, a microporous sheet screening mechanism, a first visual detection member and a suction mechanism, wherein the conveyor frame is provided with a conveyor belt, and the conveyor belt is used to convey the reagent kit, and the microporous sheet screening mechanism comprises a first loading tray, a first loading bracket, a mobile screening component, a second loading bracket and a collection box, wherein the first loading tray is located at one side of the conveyor frame, and the conveying channel of the first loading bracket is connected to the discharge port of the first loading tray, and the first loading tray is used to convey the microporous sheet into the conveying channel of the first loading bracket, and the feeding channel of the mobile screening component is connected to the discharge port of the first loading bracket. The conveying channel is connected, the discharge channel of the mobile screening component is connected with the conveying channel of the second loading bracket, and the collecting box is installed on the mobile screening component; the first visual detection component is arranged opposite to the mobile screening component, and the first visual detection component is used to detect the microporous sheets on the mobile screening component, so that the mobile screening component pushes unqualified microporous sheets into the collecting box, and the mobile screening component pushes qualified microporous sheets into the second loading bracket; the suction mechanism is arranged adjacent to the second loading bracket, and the suction mechanism is used to suck the microporous sheets in the second loading bracket into the test kit on the conveyor belt.

[0036] In the above-mentioned reagent kit assembly equipment for a blood cell analyzer, the conveyor rack conveys the reagent kit, and the first loading tray conveys the microporous sheet to the conveying channel of the first loading bracket. When the microporous sheet enters the mobile screening component, the first visual inspection component inspects the microporous sheet to determine whether the orientation of the microporous sheet is correct, and at the same time detects whether the microporous sheet has micropores. If there are no problems with the orientation and opening of the microporous sheet, it is determined to be qualified. At this time, the mobile screening component pushes the qualified microporous sheet into the conveying channel of the second loading bracket, and then the suction mechanism sucks the microporous sheet in the second loading bracket into the reagent kit on the conveyor belt to complete the assembly of the microporous sheet. For the unqualified microporous sheet, the mobile screening component pushes it into the collection box for rework. In this way, through the mutual cooperation of various mechanisms, the assembly of the microporous sheet is realized, and the degree of automation is high, which improves the production efficiency, and at the same time avoids the problem of low yield rate due to manual screening, and further improves the product yield rate.

[0037] In order to better understand the technical solutions and beneficial effects of the present invention, the present invention is further described in detail below in conjunction with specific embodiments:

[0038] like Figures 1 to 3As shown, a reagent kit assembly device 10 for a blood cell analyzer according to an embodiment includes a conveyor frame 100, a microporous sheet screening mechanism 200, a first visual detection member 300 and a suction mechanism 400. The conveyor frame 100 is provided with a conveyor belt (not shown), and the conveyor belt is used to transport the reagent kit. The microporous sheet screening mechanism 200 includes a first loading tray 210, a first loading bracket 220, a mobile screening component 230, a second loading bracket 240 and a collection box 250. The first loading tray 210 is located on one side of the conveyor frame 100, and the first loading bracket 220 is provided with a first visual detection member 300 and a suction mechanism 400. The conveying channel of 20 is connected with the discharge port of the first loading tray 210, and the first loading tray 210 is used to convey the microporous sheet to the conveying channel of the first loading bracket 220. Specifically, the first loading tray 210 transfers the microporous sheet to the first loading bracket 220 by vibration, and the feed channel of the mobile screening component 230 is connected with the conveying channel of the first loading bracket 220, and the discharge channel of the mobile screening component 230 is connected with the conveying channel of the second loading bracket 240, and the collecting box 250 is installed on the mobile screening component 230.

[0039] Furthermore, the first visual inspection component 300 is arranged opposite to the mobile screening component 230, and the first visual inspection component 300 is used to detect the microporous sheets on the mobile screening component 230, so that the mobile screening component 230 pushes unqualified microporous sheets into the collection box 250, and the mobile screening component 230 pushes qualified microporous sheets into the second loading bracket 240; the suction mechanism 400 is arranged adjacent to the second loading bracket 240, and the suction mechanism 400 is used to suck the microporous sheets in the second loading bracket 240 into the test kit on the conveyor belt.

[0040] In this embodiment, the first loading tray 210 loads the microporous sheet, and the microporous sheet enters the conveying channel of the first loading bracket 220 through the discharge port of the first loading tray 210, and then enters the feeding channel of the mobile screening component 230. The first visual inspection component 300 adopts a high-precision CCD visual camera, and the first visual inspection component 300 is used to photograph the microporous sheet on the mobile screening component 230 to determine whether the microporous sheet is qualified. Specifically, characters are provided on one side of the microporous sheet. The side with characters facing upward indicates that the assembly direction of the microporous sheet is correct, so that the subsequent microporous sheet can be accurately assembled into the test kit. When the first visual inspection component 300 detects that the characters of the microporous sheet are facing upward and the micropores of the microporous sheet are normal, the microporous sheet is judged to be qualified. At this time, the mobile screening component 230 moves to push the microporous sheet into the conveying channel of the second loading bracket 240. When the first visual inspection component 300 detects that the characters of the microporous sheet are facing downward or the micropores of the microporous sheet are abnormal, the micropores are abnormal, that is, the micropores are blocked or not opened, then the microporous sheet is judged to be unqualified. At this time, the mobile screening component 230 moves to push the microporous sheet into the collection box 250 for further collection and rework. Then, all the microporous sheets entering the second loading bracket 240 are qualified microporous sheets. When the second loading bracket 240 conveys the microporous sheet to the predetermined position, the suction component sucks the microporous sheet in the second loading bracket 240 into the test kit on the conveyor belt to complete the assembly of the microporous sheet.

[0041] In the above-mentioned reagent kit assembly equipment 10 for a blood cell analyzer, the conveyor frame 100 conveys the reagent kit, and the first loading tray 210 conveys the microporous sheet to the conveying channel of the first loading bracket 220. When the microporous sheet enters the mobile screening component 230, the first visual inspection component 300 inspects the microporous sheet to determine whether the orientation of the microporous sheet is correct, and at the same time detects whether the microporous sheet has micropores. If there are no problems with the orientation and the openings of the microporous sheet, it is judged to be qualified. At this time, the mobile screening component 230 pushes the qualified microporous sheet into the second loading bracket 240 and its conveying channel, and then the suction mechanism 400 sucks the microporous sheet in the second loading bracket 240 into the reagent kit on the conveyor belt to complete the assembly of the microporous sheet. For the unqualified microporous sheet, the mobile screening component 230 pushes it into the collection box 250 for rework. In this way, through the mutual cooperation of various mechanisms, the assembly of the microporous sheet is realized with a high degree of automation, which improves production efficiency and avoids the problem of low yield rate due to manual screening, further improving the product yield rate.

[0042] like Figure 3 and Figure 4As shown, in one embodiment, the mobile screening assembly 230 includes a first mounting frame 231, a first driving member (not shown), a first movable plate 233, a second driving member 234, a second movable plate 235, a third driving member 236 and a push block 237. The first driving member, the second driving member 234 and the third driving member 236 are all mounted on the first mounting frame 231, the power output end of the first driving member is connected to the first movable plate 233, the power output end of the second driving member 234 is connected to the second movable plate 235, the power output end of the third driving member 236 is connected to the push block 237, and the third driving member 236 is used to drive the push block 237 so that the microporous sheet of the first loading bracket 220 passes through the first movable plate 233, the first mounting frame 231 and the second movable plate 235 in sequence. It can be understood that the first driving member drives the first movable plate 233 to move, the second driving member 234 drives the second movable plate 235 to move, and the third driving member 236 drives the push block 237 to move. When the microporous sheet of the first loading bracket 220 enters the first movable plate 233, the first driving member drives the first movable plate 233 to move so that the material channel of the first movable plate 233 is connected with the material channel of the first mounting bracket 231, and the third driving member 236 drives the push block 237 to move to push the microporous sheet into the first mounting bracket 231. At this time, the first visual inspection member 300 photographs the microporous sheet on the first mounting bracket 231. If the microporous sheet is judged to be qualified, the second driving member 234 drives the second movable plate 235 to move so that the material channel of the second movable plate 235 is connected with the material channel of the first mounting bracket, and the third driving member 236 drives the push block 237 to continue to move to push the microporous sheet into the second movable plate 235, and finally enter the conveying channel of the second loading bracket 240. Further, if the first visual inspection member 300 determines that the microporous sheet is unqualified, the second driving member 234 drives the second movable plate 235 to move so that the material channel of the second movable plate 235 is staggered with the material channel of the first mounting bracket, and the third driving member 236 drives the push block 237 to move so that the push block 237 pushes the microporous sheet on the first mounting bracket 231 into the collection box 250 for further collection and rework. In this embodiment, the first driving member, the second driving member 234 and the third driving member 236 can be cylinders or motors.

[0043] like Figure 4As shown, in one embodiment, the first movable plate 233 is provided with a first conveying channel 233a, the first mounting frame 231 is provided with an intermediate conveying channel 231a, and the second movable plate 235 is provided with a second conveying channel 235a, and the two ends of the intermediate conveying channel 231a are respectively connected with the first conveying channel 233a and the second conveying channel 235a, the first conveying channel 233a is connected with the conveying channel of the first loading bracket 220, and the second conveying channel 235a is connected with the conveying channel of the second loading bracket. In this embodiment, the first driving member drives the first movable plate 233 to move so that the first conveying channel 233a of the first movable plate 233 is connected with the conveying channel of the first loading bracket 220 or the intermediate conveying channel 231a of the first mounting frame 231, and the second driving member 234 drives the second movable plate 235 to move so that the second conveying channel 235a of the second movable plate 235 is connected with the intermediate conveying channel 231a of the first mounting frame 231 or the conveying channel of the second loading bracket 240.

[0044] like Figure 4 As shown, in one embodiment, the collection box 250 is mounted on the first mounting frame 231, and the collection box 250 is located below the second driving member 234. The second driving member 234 drives the second movable plate 235 to move, so that the push block 237 pushes the unqualified microporous sheet in the middle conveying channel 231a into the collection box 250. It can be understood that the collection box 250 is located below the second driving member 234, so that when the second driving member 234 drives the second conveying channel 235a of the second movable plate 235 to stagger with the middle conveying channel 231a of the first mounting frame 231, the push block 237 pushes the microporous sheet so that the microporous sheet falls into the collection box 250 below.

[0045] In one embodiment, the first driving member is installed on one side of the first mounting frame 231, and the second driving member 234 is installed on the other side of the first mounting frame 231, so that the first movable plate 233 and the second movable plate 235 are arranged opposite to each other. It can be understood that the first driving member and the second driving member 234 are respectively installed on the two sides of the first mounting frame 231, so that the structure of the mobile screening assembly 230 is more compact, and the first movable plate 233 and the second movable plate 235 are respectively located on the two sides of the first mounting frame 231, thereby realizing the function of the first movable plate 233, the second movable plate 235 and the first mounting frame 231 being connected or staggered with each other.

[0046] like Figure 2 , Figure 3 and Figure 4As shown, in one embodiment, the number of the microporous sheet screening mechanisms 200 is two, and the two microporous sheet screening mechanisms 200 are arranged adjacent to each other, and the two microporous sheet screening mechanisms 200 are respectively used to screen and transport microporous sheets of different types. It can be understood that different types of microporous sheets need to be assembled in the two cavities of the reagent box, specifically for WBC (white blood cell) detection and RBC (red blood cell) detection. The two microporous sheet screening mechanisms 200 are arranged adjacent to each other, and the two microporous sheet screening mechanisms 200 are respectively used to screen and transport WBC microporous sheets and RBC microporous sheets, so that the suction mechanism 400 can simultaneously absorb and assemble the WBC microporous sheets and the RBC microporous sheets into the reagent box, further improving the production efficiency.

[0047] like Figure 5 As shown, in one embodiment, the suction mechanism 400 includes a second mounting frame 410, a first horizontal driving member 420, a first vertical driving member 430 and a suction cup 440. The second mounting frame 410 is arranged on one side of the conveying frame 100, the first horizontal driving member 420 is installed on the second mounting frame 410, the power output end of the first horizontal driving member 420 is connected to the power output of the first vertical driving member 430, and the power output end of the first vertical driving member 430 is connected to the suction cup 440. It can be understood that the first horizontal driving member 420 drives the first vertical driving member 430 to move in the horizontal direction, and the first vertical driving member 430 drives the suction cup 440 to move in the vertical direction, so that the suction cup 440 can move in the horizontal direction and the vertical direction, thereby sucking the microporous sheet on the second loading bracket 240 into the reagent box on the conveyor belt. Furthermore, the suction cup 440 includes a suction nozzle and an air pump, and the air pump drives the suction nozzle to absorb or release the microporous sheet. Since the microporous sheet is relatively thin, the microporous sheet can be prevented from being damaged by suction-type transportation. In this embodiment, the first horizontal driving member 420 and the first vertical driving member 430 can be motors or cylinders.

[0048] like Figure 6As shown, in one embodiment, the reagent kit assembly equipment also includes a rear pool loading mechanism 500, and the rear pool loading mechanism 500 includes a second loading tray 510, a third loading bracket 520 and a grabbing assembly 530, the second loading tray 510 is arranged adjacent to the conveying frame 100, the third loading bracket 520 is connected to the second loading tray 510, the second loading tray 510 is used to convey the rear pool to the conveying channel of the third loading bracket 520, the grabbing assembly 530 is arranged adjacent to the third loading bracket 520, and the grabbing assembly 530 is used to grab the rear pool on the third loading bracket 520 to the reagent kit on the conveyor belt. It can be understood that after the microporous sheet is loaded into the cavity of the reagent kit, the rear pool needs to be assembled. The rear pool is used to receive and process the number of cells passing through the microporous sheet. The second loading tray 510 loads the rear pool so that the second loading tray 510 transports the rear pool to the conveying channel of the third loading rack. When the rear pool reaches the predetermined position of the third loading rack, the grabbing assembly 530 grabs the rear pool and puts it into the cavity of the reagent kit, completing the assembly of the rear pool.

[0049] like Figure 6 As shown, in one embodiment, the grabbing assembly 530 includes a third mounting frame 531, a second horizontal driving member 532, a second vertical driving member 533 and a grabbing member 534, the third mounting frame 531 is arranged on one side of the conveying frame 100, the second horizontal driving member 532 is installed on the third mounting frame 531, the power output end of the second horizontal driving member 532 is connected to the second vertical driving member 533, and the power output end of the second vertical driving member 533 is connected to the grabbing member 534. It can be understood that the second horizontal driving member 532 drives the grabbing member 534 to move in the horizontal direction, and the second vertical driving member 533 drives the grabbing member 534 to move in the vertical direction, so that the grabbing member 534 grabs the rear pool on the third loading bracket 520 into the reagent box on the conveyor belt. Further, the grabbing member 534 includes a cylinder and two clamping plates, and the cylinder drives the two clamping plates to move closer or farther from each other to clamp or release the rear pool. Of course, in other embodiments, the gripping member 534 may also be an adsorption structure of the suction cup 440. Furthermore, the second horizontal driving member 532 and the second vertical driving member 533 may be cylinders or motors.

[0050] like Figure 2As shown, in one embodiment, the first visual inspection member 300 includes a fourth mounting frame 310 and a visual inspection instrument 320, the fourth mounting frame 310 is mounted on one side of the conveying frame 100, the visual inspection instrument 320 is connected to the fourth mounting frame 310, and the visual inspection instrument 320 is located above the mobile screening component 230. It can be understood that the visual inspection instrument 320 is mounted on the fourth mounting frame 310 so that the visual inspection instrument 320 is located above the mobile screening component 230, so that the visual inspection instrument 320 can take pictures and detect the microporous sheet.

[0051] It can be understood that the first loading tray 210 is a vibrating loading tray, which conveys the microporous sheets to the conveying channel of the first loading bracket 220 by vibration. At this time, the microporous sheets conveyed to the first loading bracket 220 by vibration may have the character side facing up or the character side facing down, and the microporous sheets with the character side facing up are the correct assembly direction. Although the microporous sheets with the character side facing down can be detected and discharged by the first visual inspection component 300 and the mobile screening component 230, if the number of microporous sheets with the character side facing down entering the first loading bracket 220 is large, the amount of microporous sheets discharged will be large, which may easily affect the production efficiency. Therefore, the microporous sheets need to be preliminarily screened before they enter the first loading bracket 220. Figure 7As shown, in one embodiment, the kit assembly device 10 for a blood cell analyzer further includes a microporous sheet preliminary screening mechanism 600, and the microporous sheet preliminary screening mechanism 600 includes an air jet component (not shown), a first support frame 610, and a second visual detection component 620. The first support frame 610 is disposed adjacent to the first loading tray 210, and the second visual detection component 620 is mounted on the first support frame 610. The second visual detection component 620 is disposed toward the discharge port of the first loading tray 210, and the air jet component is disposed adjacent to the first loading tray 210, and the air jet port of the air jet component is disposed toward the discharge port of the first loading tray 210. In this embodiment, the second visual detection component 620 uses a high-precision CCD visual camera, and the second visual detection component 620 photographs the microporous sheet at the discharge port of the first loading tray 210 to determine whether the microporous sheet entering the first loading bracket 220 is qualified. Specifically, when the microporous sheet passes through the exit of the first loading tray 210, the second visual inspection component 620 photographs the microporous sheet and uploads it to the control system. If the character side of the microporous sheet is facing upward at this time, the microporous sheet is judged to be qualified, and the microporous sheet can enter the conveying channel of the first loading bracket 220. If the character side of the microporous sheet is facing downward at this time, the microporous sheet is judged to be unqualified. At this time, the control system outputs a signal to enable the jet component to spray the discharge port of the first loading tray 210. Under the action of the jet, the microporous sheet at the discharge port is blown back to the first loading tray 210 for re-vibration loading, ensuring that the microporous sheets at the discharge port of the first loading tray 210 are all with the character side facing upward. In this way, by preliminarily screening the microporous sheets, the number of discharges caused by incorrect orientation of the microporous sheets at the mobile screening component 230 is reduced, thereby improving production efficiency. Furthermore, the jet component can be a spray gun, and the jet component is aimed at microporous sheets with larger thickness and weight. The jet component sprays toward the discharge port of the first loading tray 210, so that the microporous sheets sprayed by the jet component at the discharge port are blown back into the first loading tray 210, that is, other microporous sheets around the microporous sheet will not be affected by the jet component.

[0052] Furthermore, when targeting thin and light microporous sheets, the air jetting member may easily cause other microporous sheets around the microporous sheet being air jetted to be blown back to the first loading tray 210, resulting in a low precision of preliminary screening of microporous sheets. Therefore, in order to improve the preliminary screening precision of thin and light microporous sheets, as shown in FIG. Figure 7 and Figure 8As shown, in one embodiment, the microporous sheet preliminary screening mechanism 600 also includes a ejector pin assembly 630, and the ejector pin assembly 630 includes a lifting drive member 631 and an ejector pin 632, and the lifting drive member 631 is installed in the first loading tray 210, and the power output end of the lifting drive member 631 is connected to the ejector pin 632, and a avoidance hole 211 is opened at the discharge port of the first loading tray 210, and the lifting drive member 631 is used to drive the ejector pin 632 to pass through the avoidance hole 211. In this embodiment, when the microporous sheet passes through the exit of the first loading tray 210, the second visual inspection component 620 takes a picture of the microporous sheet and uploads it to the control system. If the character side of the microporous sheet is facing upward at this time, the microporous sheet is judged to be qualified, and the microporous sheet can enter the conveying channel of the first loading bracket 220. If the character side of the microporous sheet is facing downward at this time, the microporous sheet is judged to be unqualified. At this time, the control system outputs a signal to make the lifting drive component 631 drive the ejector pin 632 to pass through the avoidance hole 211 to flip the microporous sheet, so that the microporous sheet is turned over, and then the character side of the microporous sheet is facing upward to complete the preliminary screening of the microporous sheet. In this way, through the mutual cooperation of the lifting drive component 631, the ejector pin 632 and the second visual inspection component 620, the ejector pin 632 can flip a specific microporous sheet, that is, it will not affect the surrounding microporous sheets, especially for microporous sheets with thin thickness and light weight, the accuracy of preliminary screening is higher. Furthermore, the lifting driving member 631 is a cylinder, the number of the ejector pins 632 can be multiple, the number of the avoidance holes 211 is also multiple, and the ejector pins 632 are arranged in a one-to-one correspondence with the avoidance holes 211, so that when the second visual inspection member 620 takes pictures and inspects multiple microporous sheets, the ejector pins 632 can flip over the corresponding microporous sheets, thereby improving the screening efficiency.

[0053] Furthermore, in order to prevent the ejector pin 632 from damaging the surface of the microporous sheet during the process of flipping the microporous sheet, in one embodiment, a buffer pad 633 is provided at one end of the ejector pin 632 away from the ejection drive member 631, and the diameter of the buffer pad 633 is greater than the diameter of the ejector pin 632. In this embodiment, the diameter of the buffer pad 633 is greater than the diameter of the ejector pin 632, and the diameter of the buffer pad 633 is smaller than the diameter of the avoidance hole 211, so that when the ejection drive member 631 drives the ejector pin 632 to move, the buffer pad 633 passes through the avoidance hole 211 and contacts the microporous sheet, and the buffer pad 633 increases the contact area with the microporous sheet, thereby making the microporous sheet more uniformly stressed to avoid damaging the microporous sheet. Furthermore, the buffer pad 633 is a silica gel or rubber structure, so that the buffer pad 633 has a buffering effect when it contacts the microporous sheet, further reducing the force on the microporous sheet. In other embodiments, the buffer pad 633 can also be a spring structure.

[0054] Compared with the prior art, the present invention has at least the following advantages:

[0055] In the above-mentioned reagent kit assembly equipment 10 for a blood cell analyzer, the conveyor frame 100 conveys the reagent kit, and the first loading tray 210 conveys the microporous sheet to the conveying channel of the first loading bracket 220. When the microporous sheet enters the mobile screening component 230, the first visual inspection component 300 inspects the microporous sheet to determine whether the orientation of the microporous sheet is correct, and at the same time detects whether the microporous sheet has micropores. If there are no problems with the orientation and the openings of the microporous sheet, it is judged to be qualified. At this time, the mobile screening component 230 pushes the qualified microporous sheet into the second loading bracket 240 and its conveying channel, and then the suction mechanism 400 sucks the microporous sheet in the second loading bracket 240 into the reagent kit on the conveyor belt to complete the assembly of the microporous sheet. For the unqualified microporous sheet, the mobile screening component 230 pushes it into the collection box 250 for rework. In this way, through the mutual cooperation of various mechanisms, the assembly of the microporous sheet is realized with a high degree of automation, which improves production efficiency and avoids the problem of low yield rate due to manual screening, further improving the product yield rate.

It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present disclosure, and these all belong to the protection scope of the present disclosure. Therefore, the protection scope of the patent of the present disclosure shall be subject to the attached claims.
