Description

Technical Field

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

[0002] A blood cell analyzer, also known as a blood cell analyzer, a blood cell analyzer, a blood cell counter, etc., is one of the most widely used instruments for clinical testing 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 reagent box, such as a reagent box disclosed in Chinese patent application number CN202121839169.8, and a reagent box and a POCT blood cell analyzer disclosed in 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). 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 manually screened, this has the 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, which has the 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 kit assembly device for the blood cell analyzer comprises a conveying frame, a microwell sheet screening mechanism, a first visual detection member and a suction mechanism.

[0036] The kit assembly device for the blood cell analyzer, the conveying frame conveys the kit, the first feeding disc conveys the microwell sheet into the conveying channel of the first feeding support, when the microwell sheet enters the mobile screening assembly, the first visual detection member detects the microwell sheet to determine whether the orientation of the microwell sheet is correct and whether the microwell sheet has an open microwell, if both the orientation and the open microwell are correct, the mobile screening assembly pushes the qualified microwell sheet into the conveying channel of the second feeding support, then the suction mechanism sucks the microwell sheet in the second feeding support into the kit on the conveying belt to complete the assembly of the microwell sheet, and the mobile screening assembly pushes the unqualified microwell sheet into the collection box for rework.

[0037] In order to better understand the technical solutions and beneficial effects of the present disclosure, the present disclosure will be further described in detail below in combination with specific embodiments.

[0038] As Figures 1 to 3As shown, the kit assembly device 10 for blood cell analyzer in an embodiment comprises a conveying frame 100, a micro-well plate screening mechanism 200, a first visual detection member 300 and a suction mechanism 400. The conveying frame 100 is provided with a conveying belt (not shown in the figure) for conveying the kit. The micro-well plate screening mechanism 200 comprises a first feeding disc 210, a first feeding support 220, a moving screening assembly 230, a second feeding support 240 and a collection box 250. The first feeding disc 210 is located at one side of the conveying frame 100. The conveying passage of the first feeding support 220 is in communication with the discharge port of the first feeding disc 210. The first feeding disc 210 is used to convey the micro-well plate into the conveying passage of the first feeding support 220. Specifically, the first feeding disc 210 transfers the micro-well plate to the first feeding support 220 by vibration. The feeding passage of the moving screening assembly 230 is in communication with the conveying passage of the first feeding support 220. The discharge passage of the moving screening assembly 230 is in communication with the conveying passage of the second feeding support 240. The collection box 250 is installed on the moving screening assembly 230.

[0039] Further, the first visual detection member 300 is arranged opposite to the moving screening assembly 230. The first visual detection member 300 is used to detect the micro-well plate on the moving screening assembly 230, so that the moving screening assembly 230 pushes the unqualified micro-well plate into the collection box 250 and pushes the qualified micro-well plate into the second feeding support 240. The suction mechanism 400 is arranged adjacent to the second feeding support 240. The suction mechanism 400 is used to suck the micro-well plate in the second feeding support 240 into the kit on the conveying belt.

[0040] In the embodiment, the first feeding disc 210 feeds the microwell sheet, the microwell sheet enters the conveying channel of the first feeding support 220 through the discharge port of the first feeding disc 210, and then the microwell sheet enters the feeding channel of the moving screening assembly 230. The first visual detection member 300 adopts a high-precision CCD visual camera, and the microwell sheet on the moving screening assembly 230 is photographed by the first visual detection member 300 to determine whether the microwell sheet is qualified. Specifically, one side of the microwell sheet is provided with characters, and the side with the characters upward indicates that the assembly direction of the microwell sheet is correct, so that the microwell sheet can be accurately assembled into the reagent box in the subsequent process. When the first visual detection member 300 detects that the characters of the microwell sheet are upward and the microwells of the microwell sheet are normal, it is determined that the microwell sheet is qualified. At this time, the moving screening assembly 230 moves to push the microwell sheet into the conveying channel of the second feeding support 240. When the first visual detection member 300 detects that the characters of the microwell sheet are downward or the microwells of the microwell sheet are abnormal, that is, the microwells are blocked or not opened, it is determined that the microwell sheet is unqualified. At this time, the moving screening assembly 230 moves to push the microwell sheet into the collection box 250 for further collection and rework. Then, all the microwell sheets entering the second feeding support 240 are qualified microwell sheets. When the second feeding support 240 conveys the microwell sheets to the predetermined position, the suction assembly sucks the microwell sheets in the second feeding support 240 into the reagent box on the conveying belt, completing the assembly of the microwell sheets.

[0041] The above-mentioned reagent box assembly equipment 10 for a blood cell analyzer, the conveying frame 100 conveys the reagent box, the first feeding disc 210 conveys the microwell sheet into the conveying channel of the first feeding support 220. When the microwell sheet enters the moving screening assembly 230, the first visual detection member 300 detects the microwell sheet to determine whether the orientation of the microwell sheet is correct and whether the microwell sheet has an opened microwell. If the orientation and the opening of the microwell sheet are both correct, it is determined that the microwell sheet is qualified. At this time, the moving screening assembly 230 pushes the qualified microwell sheet into the conveying channel of the second feeding support 240. Then, the suction mechanism 400 sucks the microwell sheet in the second feeding support 240 into the reagent box on the conveying belt, completing the assembly of the microwell sheet. For the unqualified microwell sheet, the moving screening assembly 230 pushes it into the collection box 250 for rework. In this way, the assembly of the microwell sheet is realized through the cooperation of each mechanism, the degree of automation is high, the production efficiency is improved, and the problem of low yield rate caused by manual screening is avoided, further improving the yield rate of the product.

[0042] As Figure 3 and Figure 4As shown, in one of the embodiments, the moving screening assembly 230 comprises a first mounting frame 231, a first driving member (not shown), a first moving plate 233, a second driving member 234, a second moving 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 with the first moving plate 233, the power output end of the second driving member 234 is connected with the second moving plate 235, the power output end of the third driving member 236 is connected with the push block 237, the third driving member 236 is used to drive the push block 237 to make the microporous sheet of the first feeding support 220 sequentially pass through the first moving plate 233, the first mounting frame 231 and the second moving plate 235. It can be understood that the first driving member drives the first moving plate 233 to move, the second driving member 234 drives the second moving plate 235 to move, the third driving member 236 drives the push block 237 to move, when the microporous sheet of the first feeding support 220 enters the first moving plate 233, the first driving member drives the first moving plate 233 to move to make the material channel of the first moving plate 233 communicate with the material channel of the first mounting frame 231, the third driving member 236 drives the push block 237 to move to push the microporous sheet into the first mounting frame 231, at this time, the first visual detection member 300 shoots the microporous sheet on the first mounting frame 231, if it is judged that the microporous sheet is qualified, the second driving member 234 drives the second moving plate 235 to move to make the material channel of the second moving plate 235 communicate with the material channel of the first mounting support, the third driving member 236 drives the push block 237 to continue to move to push the microporous sheet into the second moving plate 235 and finally into the conveying channel of the second feeding support 240. Further, if the first visual detection member 300 judges that the microporous sheet is unqualified, the second driving member 234 drives the second moving plate 235 to move to make the material channel of the second moving plate 235 staggered with the material channel of the first mounting support, the third driving member 236 drives the push block 237 to move to make the push block 237 push the microporous sheet on the first mounting frame 231 to fall into the collecting box 250 to further collect and rework. In this embodiment, the first driving member, the second driving member 234 and the third driving member 236 can be air cylinders or motors.

In this embodiment, the first driving member drives the first moving plate 233 to move, so that the first conveying channel 233a of the first moving plate 233 is communicated with the conveying channel of the first feeding support 220 or the intermediate conveying channel 231a of the first mounting frame 231, and the second driving member 234 drives the second moving plate 235 to move, so that the second conveying channel 235a of the second moving plate 235 is communicated with the intermediate conveying channel 231a of the first mounting frame 231 or the conveying channel of the second feeding support 240.

[0044] As shown in the drawings, Figure 4 As shown, in one of the embodiments, the collecting box 250 is mounted on the first mounting frame 231, the collecting box 250 is located below the second driving member 234, the second driving member 234 drives the second moving plate 235 to move, so that the push block 237 pushes the unqualified microporous sheet in the intermediate conveying channel 231a into the collecting box 250. It can be understood that the collecting 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 moving plate 235 to be staggered with the intermediate conveying channel 231a of the first mounting frame 231, the push block 237 pushes the microporous sheet to make the microporous sheet fall into the collecting box 250 below.

[0045] In one of the embodiments, the first driving member is mounted on one side of the first mounting frame 231, and the second driving member 234 is mounted on the other side of the first mounting frame 231, so that the first moving plate 233 and the second moving 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 mounted on the two sides of the first mounting frame 231, so that the structure of the moving screening assembly 230 is more compact, and the first moving plate 233 and the second moving plate 235 are respectively located on the two sides of the first mounting frame 231, thereby realizing the functions of mutual communication or staggering of the first moving plate 233, the second moving plate 235 and the first mounting frame 231.

[0046] As shown in the drawings, Figure 2 , Figure 3 and Figure 4As shown in the drawings, in one embodiment, the number of the micro-well plate screening mechanisms 200 is two, and the two micro-well plate screening mechanisms 200 are arranged adjacently, and the two micro-well plate screening mechanisms 200 are respectively used for screening and conveying different types of micro-well plates. It can be understood that different types of micro-well plates need to be assembled in the two cavities of the kit respectively, specifically for WBC (white blood cell) detection and RBC (red blood cell) detection, the two micro-well plate screening mechanisms 200 are arranged adjacently, and the two micro-well plate screening mechanisms 200 are respectively used for screening and conveying WBC micro-well plates and RBC micro-well plates, so that the suction mechanism 400 can simultaneously suck and assemble the WBC micro-well plates and the RBC micro-well plates into the kit, and the production efficiency is further improved.

[0047] As shown in the drawings, Figure 5 As shown in the drawings, 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 disc 440, the second mounting frame 410 is arranged on one side of the conveying frame 100, the first horizontal driving member 420 is mounted on the second mounting frame 410, the power output end of the first horizontal driving member 420 is connected with the power output of the first vertical driving member 430, and the power output end of the first vertical driving member 430 is connected with the suction disc 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 disc 440 to move in the vertical direction, so that the suction disc 440 can move in the horizontal direction and the vertical direction, and then the micro-well plate on the second upper material support 240 is sucked into the kit on the conveying belt. Further, the suction disc 440 includes a suction nozzle and an air pump, and the air pump drives the suction nozzle to suck or release the micro-well plate, and since the micro-well plate is thin, the suction conveying can avoid damaging the micro-well plate.

[0048] As shown in the drawings, Figure 6As shown, in one embodiment, the kit assembly device further comprises a rear pool loading mechanism 500, which comprises a second loading disc 510, a third loading support 520 and a grabbing assembly 530. The second loading disc 510 is arranged adjacent to the conveying frame 100. The third loading support 520 is connected with the second loading disc 510. The second loading disc 510 is used to convey the rear pool into the conveying passage of the third loading support 520. The grabbing assembly 530 is arranged adjacent to the third loading support 520. The grabbing assembly 530 is used to grab the rear pool on the third loading support 520 into the kit on the conveying belt. It can be understood that the rear pool needs to be assembled after the micro-hole sheet is loaded into the cavity of the kit. The rear pool is used to receive and process the cell quantity through the micro-hole sheet. The second loading disc 510 loads the rear pool, so that the second loading disc 510 conveys the rear pool into the conveying passage of the third loading support. When the rear pool reaches the predetermined position of the third loading support, the grabbing assembly 530 grabs the rear pool into the cavity of the kit, and the assembly of the rear pool is completed.

The power output end of the second horizontal driving member 532 is connected with the second vertical driving member 533. The power output end of the second vertical driving member 533 is connected with 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 support 520 into the kit on the conveying belt. Further, the grabbing member 534 comprises a cylinder and two clamping plates. The cylinder drives the two clamping plates to move close to or away from each other, so as to clamp or release the rear pool. Of course, in other embodiments, the grabbing member 534 can also be in the suction type structure of the suction disc 440. Further, the second horizontal driving member 532 and the second vertical driving member 533 can be cylinders or motors.

[0050] As shown, Figure 2As shown, in one of the embodiments, the first visual detection member 300 comprises a fourth mounting frame 310 and a visual detection instrument 320, the fourth mounting frame 310 is mounted on one side of the conveying frame 100, the visual detection instrument 320 is connected with the fourth mounting frame 310, and the visual detection instrument 320 is located above the mobile screening assembly 230. It can be understood that the visual detection instrument 320 is mounted on the fourth mounting frame 310 so that the visual detection instrument 320 is located above the mobile screening assembly 230, so as to facilitate the visual detection instrument 320 to take a photo of the microporous sheet for detection.

[0051] It can be understood that the first feeding disc 210 is a vibrating feeding disc, and the microporous sheet is conveyed into the conveying channel of the first feeding support 220 through vibration. At this time, the microporous sheet conveyed into the first feeding support 220 through vibration has the case of character face up or character face down, and the microporous sheet with character face up is the correct assembly direction. Although the microporous sheet with character face down can be detected and discharged through the cooperation of the first visual detection member 300 and the mobile screening assembly 230, if the number of microporous sheets with character face down entering the first feeding support 220 is relatively large, the amount of microporous sheets discharged will be relatively large, which will easily affect the production efficiency. Therefore, the microporous sheet needs to be preliminarily screened before entering the first feeding support 220. For example, Figure 7As shown, in one of the embodiments, the kit assembly device 10 for blood cell analyzer further comprises a microwell plate preliminary screening mechanism 600, the microwell plate preliminary screening mechanism 600 comprises an air jet (not shown in the figure), a first support frame 610 and a second visual detection piece 620, the first support frame 610 is arranged adjacent to the first feeding disc 210, the second visual detection piece 620 is installed on the first support frame 610, the second visual detection piece 620 is arranged towards the discharge port of the first feeding disc 210, and the air jet is arranged adjacent to the first feeding disc 210, and the air jet port of the air jet is arranged towards the discharge port of the first feeding disc 210. In this embodiment, the second visual detection piece 620 adopts a high-precision CCD visual camera, and the second visual detection piece 620 photographs the microwell plate at the discharge port of the first feeding disc 210 to determine whether the microwell plate entering the first feeding support 220 is qualified. Specifically, when the microwell plate passes through the outlet of the first feeding disc 210, the second visual detection piece 620 photographs the microwell plate and uploads it to the control system, if the character surface of the microwell plate faces upwards at this time, it is judged that the microwell plate is qualified, then the microwell plate can enter the conveying channel of the first feeding support 220, if the character surface of the microwell plate faces downwards at this time, it is judged that the microwell plate is unqualified, at this time the control system outputs a signal to make the air jet jet at the discharge port of the first feeding disc 210, under the action of the jet, the microwell plate at the discharge port is blown back to the first feeding disc 210 to re-vibrate and feed, so as to ensure that the microwell plate passing through the discharge port of the first feeding disc 210 is all with the character surface facing upwards, so that the preliminary screening of the microwell plate reduces the number of discharges due to incorrect orientation of the moving screening assembly 230, thereby improving the production efficiency. Further, the air jet can be a spray gun, and the air jet is for microwell plates with large thickness and weight, and the air jet sprays towards the discharge port of the first feeding disc 210, so that the microwell plate sprayed by the air jet is blown back into the first feeding disc 210, that is, other microwell plates around the microwell plate will not be affected by the air jet.

[0052] Further, when it is for microwell plates with thin thickness and light weight, the air jet is easy to blow other microwell plates around the microwell plate back to the first feeding disc 210 when spraying, resulting in low accuracy of microwell plate preliminary screening. Therefore, in order to improve the preliminary screening accuracy of microwell plates with thin thickness and light weight, such as Figure 7 and Figure 8As shown, in one of the embodiments, the microporous sheet preliminary screening mechanism 600 further comprises a ejector assembly 630, the ejector assembly 630 comprises an ejector driving element 631 and an ejector pin 632, the ejector driving element 631 is installed in the first feeding disc 210, the power output end of the ejector driving element 631 is connected with the ejector pin 632, and a position avoiding hole 211 is formed at the outlet of the first feeding disc 210, and the ejector driving element 631 is used to drive the ejector pin 632 to pass through the position avoiding hole 211. In this embodiment, when the microporous sheet passes through the outlet of the first feeding disc 210, the second visual detection element 620 takes a photo of the microporous sheet and uploads it to the control system, if the character surface of the microporous sheet faces upward at this time, it is judged that the microporous sheet is qualified, then the microporous sheet can enter the conveying channel of the first feeding support 220, if the character surface of the microporous sheet faces downward at this time, it is judged that the microporous sheet is unqualified, at this time the control system outputs a signal to make the ejector driving element 631 drive the ejector pin 632 to pass through the position avoiding hole 211, so as to turn over the microporous sheet, so as to make the character surface of the microporous sheet face upward, so as to complete the preliminary screening of the microporous sheet. In this way, through the cooperation of the ejector driving element 631, the ejector pin 632 and the second visual detection element 620, the ejector pin 632 can turn over the specific microporous sheet, that is, it will not affect the surrounding microporous sheets, especially for the microporous sheets with thin thickness and light weight, the precision of preliminary screening is higher. Further, the ejector driving element 631 is a pneumatic cylinder, the number of the ejector pins 632 can be multiple, and the number of the position avoiding holes 211 is also multiple, the ejector pins 632 and the position avoiding holes 211 are arranged one by one, so that when the second visual detection element 620 takes a photo of multiple microporous sheets for detection, the ejector pins 632 can turn over the corresponding microporous sheets, thereby improving the screening efficiency.

[0053] Further, in order to prevent the surface of the microporous sheet from being damaged in the process of turning over the microporous sheet by the ejector pin 632, in one of the embodiments, a buffer pad 633 is arranged at the end of the ejector pin 632 away from the ejector driving element 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 less than the diameter of the position avoiding hole 211, so that when the ejector driving element 631 drives the ejector pin 632 to move, the buffer pad 633 passes through the position avoiding hole 211 and contacts the microporous sheet, and the buffer pad 633 increases the contact area with the microporous sheet, thereby making the force on the microporous sheet more uniform, so as to avoid damaging the microporous sheet. Further, the buffer pad 633 is made of 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 acting 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 disclosure has at least the following advantages:

[0055] The kit assembly device 10 for the blood cell analyzer, the conveying frame 100 conveys the kit, the first feeding disc 210 conveys the microwell sheet into the conveying channel of the first feeding support 220, when the microwell sheet enters the moving screening assembly 230, the first visual detection member 300 detects the microwell sheet to determine whether the orientation of the microwell sheet is correct, and whether the microwell sheet has an opening microwell, if the orientation and the opening microwell are both correct, the microwell sheet is determined to be qualified, at this time, the moving screening assembly 230 pushes the qualified microwell sheet into the conveying channel of the second feeding support 240, then the suction mechanism 400 sucks the microwell sheet in the second feeding support 240 into the kit on the conveying belt to complete the assembly of the microwell sheet, and the unqualified microwell sheet is pushed into the collection box 250 by the moving screening assembly 230 to be reworked. In this way, the assembly of the microwell sheet is realized through the cooperation of each mechanism, the degree of automation is high, the production efficiency is improved, the problem of low yield rate caused by manual screening is avoided, and the product yield rate is further improved.
