Description

Technical Field

[0001] This utility model relates to the field of conveying devices, and particularly to a conveying device for test strips in a urine analyzer. Background Technology

[0002] A urine analyzer is a medical device used to detect the components of urine, widely used in hospitals, laboratories, and home health monitoring. Urine analysis test strips are its core consumables, typically composed of multiple layers of chemical reagent zones, capable of detecting various parameters in urine. The transport toothed plate of the urine analyzer ensures that the test strips are not damaged or contaminated during transportation, storage, and automated testing, thereby improving the detection accuracy of the test strips.

[0003] On the Chinese patent website, patent CN218036854U discloses a test strip transport and detection mechanism for a urine analyzer. This mechanism includes a fixed base plate, with a strip transport platform fixedly connected to its upper end. The strip transport platform has a sample placement optical coupler, and the fixed base plate has a detection position optical coupler and a reset position optical coupler. A horizontal guide rail is fixedly connected to the upper end of the fixed base plate, and a guide rail connecting plate is slidably connected to its upper end. A vertical guide rail is fixedly connected to the guide rail connecting plate, and a cam connecting plate is slidably connected to the guide rail connecting plate. A fork connecting plate is fixedly connected to the upper end of the cam connecting plate, and detection forks and strip pushing forks arranged correspondingly are fixedly connected to the fork connecting plate. The strip transport platform has sliding holes that mate with the detection forks and strip pushing forks. A detection guide rail is fixedly connected to one end of the strip transport platform, and an optical component is slidably connected to the detection guide rail. This test strip transport and detection mechanism for a urine analyzer enables synchronous strip pushing and transport, greatly improving detection efficiency.

[0004] However, the transport unit toothed plate of the test strip is a single-sided toothed plate, which poses a risk of the test strip tilting during transport. It is necessary to manually straighten the tilted test strip, which reduces the transport efficiency. Summary of the Invention

[0005] In view of this, the present invention provides a conveying device for test strips in a urine analyzer to solve the above problems.

[0006] A transport device for urine analyzer test strips, comprising a support, a carrier plate mounted on the support, a reciprocating lifting transport assembly fixedly mounted in the support, and a double-sided toothed plate mounted on and driven by the reciprocating lifting transport assembly. The carrier plate includes, in sequence, a strip-pushing area, a sample-dispensing area, a buffer area, and a blank scanning area. The strip-pushing area has two parallel strip-pushing grooves extending to the buffer area. The blank scanning area has two slots extending from the blank scanning area to the strip-pushing area and offset from the strip-pushing grooves. The reciprocating lifting transport assembly includes a horizontal drive assembly and a vertical drive assembly mounted on the horizontal drive assembly. The double-sided toothed plate is mounted on the vertical drive assembly. The double-sided toothed plate includes a double-sided toothed plate body, two toothed racks oppositely mounted on both sides of the double-sided toothed plate, and a second strip-pushing groove between the toothed racks. The two toothed racks are driven by the vertical drive assembly and enter or exit the carrier plate through the slots. The rack has multiple transport teeth evenly spaced, and multiple transport grooves are arranged between the transport teeth. The transport teeth and transport grooves on different double-sided toothed plates are correspondingly arranged, and the test strip is supported and transported through two corresponding transport grooves. The second pusher groove overlaps with the end of the pusher groove closest to the buffer area.

[0007] Furthermore, the vertical drive assembly includes a lifting motor, an eccentric shaft disposed at the output end of the lifting motor, a bearing fixedly disposed at the end of the eccentric shaft, a vertical slide rail fixedly disposed on the lifting motor via a mounting plate, a vertical slider slidably disposed on the vertical slide rail, and a toothed plate support plate disposed on the vertical slider. The vertical drive assembly is fixedly disposed above the horizontal drive assembly via a guide rail adapter plate. The toothed plate support plate is provided with an oblong hole, and the bearing passes through the oblong hole.

[0008] Furthermore, the extension direction of the waist-shaped hole is parallel to the extension direction of the horizontal drive assembly.

[0009] Furthermore, the delivery device for the urine analyzer test strip includes a pushing component disposed in the support, a test head assembly disposed on the carrier plate, and multiple reset detection optocouplers.

[0010] Furthermore, the support includes two upright plates and a base plate that is connected to the two upright plates on the same side by fasteners.

[0011] Furthermore, the pushing component includes a second horizontal driving component and a fork mounted on the second horizontal driving component via a mounting bracket. The fork is fixedly mounted on the second horizontal driving component and is driven by the second horizontal driving component to move in the push bar groove.

[0012] Furthermore, the test head assembly includes a third horizontal drive assembly positioned above the blank scanning area, and a test head movably disposed on the third horizontal drive assembly. The third horizontal drive assembly drives the test head to move in the test strip extension direction to perform scanning in cooperation with the test head.

[0013] Furthermore, multiple reset detection optocouplers are respectively disposed in the reciprocating lifting and conveying component, the pushing component, and the test head component. By correspondingly setting reset optocoupler push plates, the reset detection of the above components is realized.

[0014] Compared with existing technologies, this utility model provides a conveying device for urine analyzer test strips, which incorporates a reciprocating lifting conveying assembly and a double-sided toothed plate to solve the problem of slanted strips during the strip pushing process and to achieve the transport of the test strip by the double-sided toothed plate. The transport teeth and transport grooves on different racks of the double-sided toothed plate are correspondingly arranged, and the test strip is supported and transported through the corresponding two transport grooves, avoiding slanted strip transport. The second push strip groove overlaps with the end of the push strip groove near the buffer area, allowing the test strip to be pushed from the push strip area to the buffer area and received by the double-sided toothed plate. Driven by the reciprocating lifting conveying assembly, the double-sided gears move horizontally and vertically, transporting the test strip from the buffer area to the slot on the side away from the push strip area, thus pushing the test strip out of the support plate.

They are used only for the convenience of describing the present invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0022] Please see Figures 1 to 5 This is a structural schematic diagram of a transport device for urine analyzer test strips provided by this utility model. The transport device for urine analyzer test strips includes a support 10, a support plate 20 disposed on the support 10, a reciprocating lifting and conveying assembly 30 fixedly disposed in the support 10, a double-sided toothed plate 40 disposed on and pushed by the reciprocating lifting and conveying assembly 30, a pushing assembly 50 disposed in the support 10, a test head assembly 60 disposed on the support plate 20, and multiple reset detection optocouplers 70. It is conceivable that the transport device for urine analyzer test strips also includes other functional modules, such as magnetic pins, which are technologies known to those skilled in the art and will not be described in detail here.

[0023] The bracket 10 includes two upright plates 11 and a base plate 12 fixed to the same side of the two upright plates 11 by fasteners. The bracket 10 is used to fix and support the reciprocating lifting and conveying assembly 30, the double-sided toothed plate 40, and the pushing assembly 50. Therefore, the bracket 10 also has various functional components, such as screws, bolts, clamps, mounting brackets, etc., to complete the installation and assembly of the above functional modules. These can be set according to actual needs, and will not be described in detail here.

[0024] The carrier plate 20 includes a push strip area 21, a sample dispensing area 22, a buffer area 23, and a blank scanning area 24 arranged sequentially. The push strip area 21 has two parallel push strip grooves 211. The push strip grooves 211 extend to the buffer area 23, allowing the test strip to be pushed into the sample dispensing area 22 and then pushed into the buffer area 23 after dispensing, finally transported to a designated location by the double-sided toothed plate 40. The sample dispensing area 22 is the area where the test strip is dispensed, and an instrument is positioned above the test strip to dispense the sample. The buffer area 23 serves as a transition between the blank scanning area 24 and the sample dispensing area 22, and is used to hold the test strip being transported to the blank scanning area 24. The blank scanning area 24 has two slots 241. The slot 241 extends from the blank scanning area 24 to the push strip area 21 and is offset from the push strip groove 211 to avoid interference between the push component 50 moving in the push strip groove 211 and the double-sided toothed plate 40 moving in the slot 241.

[0025] The reciprocating lifting and conveying assembly 30 includes a horizontal drive assembly 31 and a vertical drive assembly 32 disposed on the horizontal drive assembly 31.

[0026] The horizontal drive assembly 31 includes a first mounting plate 311, a horizontal motor 312 mounted on the first mounting plate 311, a synchronous belt device 313 mounted on the first mounting plate 311, a slide rail device 314 disposed on the synchronous belt device 313, and a clamping device 315 fixing the slide rail device 314 to the synchronous belt device 313. The running direction of the synchronous belt device 313 is the same as the extension direction of the slot 241. The horizontal motor 312 drives the synchronous belt device 313. The clamping device 315 causes the slide rail device 314 to move synchronously with the synchronous belt device 313. The vertical drive assembly 32 is disposed above the slide rail device 314. The horizontal drive assembly 31 pushes the double-sided toothed plate 40 to move in the extension direction of the slot 241 through the vertical drive assembly 32. The horizontal drive assembly 31 is a general technology and will not be described in detail here.

[0027] The vertical drive assembly 32 includes a lifting motor 321, an eccentric shaft 322 disposed at the output end of the lifting motor 321, a bearing 323 fixedly disposed at the end of the eccentric shaft 322, a vertical slide rail 324 fixedly disposed on the lifting motor 321 via a mounting plate, a vertical slider 325 slidably disposed on the vertical slide rail 324, and a toothed plate support plate 326 disposed on the vertical slider 325. The vertical drive assembly 32 is used to push the double-sided toothed plates 40, causing them to reciprocate up and down in the slot 241. The vertical drive assembly 32 is fixedly disposed above the horizontal drive assembly 31 via a guide rail adapter plate. The toothed plate support plate 326 has a waist-shaped hole 3261. The extension direction of the oblong hole 3261 is parallel to the extension direction of the horizontal drive assembly 31. The bearing 323 passes through the oblong hole 3261, eliminating the movement distance of the bearing 323 in the direction of movement of the horizontal drive assembly 31 when the eccentric shaft 322 drives the bearing 323 in circumferential motion. Therefore, it only drives the toothed plate support plate 326 to move vertically reciprocally. The toothed plate support plate 326 is supported by the bearing 323. Since the toothed plate support plate 326 is fixedly connected to the vertical slider 325, and the vertical slider 325 is movably connected to the vertical slide rail 324, the vertical slider 325 can drive the toothed plate support plate 326 to move along the vertical slide rail 324. When the lifting motor 321 is started, the eccentric shaft 322 rotates eccentrically, and the bearing 323 moves in a circular motion in the waist-shaped hole 3261. However, since the waist-shaped hole 3261 eliminates horizontal movement, only the vertical slider 325 moves on the vertical slide rail 324, pushing the double-sided toothed plate 40 out of the support plate 20 through the slot 241, or pulling the double-sided toothed plate 40 below the support plate 20, thereby supporting and lowering the test paper on the buffer area 23 and the blank scanning area 24 at the alignment point.

[0028] The double-sided toothed plate 40 is mounted on the vertical drive assembly 32. The double-sided toothed plate 40 includes a double-sided toothed plate body 41, two toothed racks 42 disposed opposite each other on both sides of the double-sided toothed plate 40, and a second pusher groove 43 disposed on the toothed racks 42. The two toothed racks 42 are driven by the vertical drive assembly 32 and enter or exit the support plate 20 through the slots 241. The extending direction of the two toothed racks 42 is the same as the extending direction of the slots 241. Multiple transport teeth 421 are equidistantly arranged on the toothed racks 42, and multiple transport grooves 422 are disposed between the transport teeth 421. The transport teeth 421 and transport grooves 422 on different toothed racks 42 are correspondingly arranged, and the test strip is supported and transported through the corresponding two transport grooves 422, preventing the test strip from tilting during transport. The second pusher groove 43 overlaps with the end of the pusher groove 211 near the buffer area 23, so that the pusher component 50 can smoothly slide from the pusher groove 211 into the second pusher groove 211, ensuring that the test strip can be received by the double-sided toothed plate 40.

[0029] The pushing component 50 includes a second horizontal drive component 51 and a shift fork 52 mounted on the second horizontal drive component 51 via a mounting bracket. The second horizontal drive component 51 includes a second mounting plate 511, a second horizontal motor 512 mounted on the second mounting plate 511, a second synchronous belt device 513 driven by the second horizontal motor 512, a second slide rail device 514 fixedly mounted on the second synchronous belt device 513, and a second pressing component 515 fixedly connecting the second synchronous belt device 513 and the second slide rail device 514. The second horizontal drive component 51 is modularly configured and is used to push the shift fork 52 to move within the pusher groove 211. The running direction of the second synchronous belt device 513 is the same as the extension direction of the pusher groove 211. The second horizontal drive component 51 is a general structure and will not be described in detail here. The shift fork 52 is fixedly mounted on the second horizontal drive component 51 and is driven by the second horizontal drive component 51 to move within the pusher groove 211.

[0030] The test head assembly 60 includes a third horizontal drive assembly 61 positioned above the blank scanning area 24, and a test head 62 movably mounted on the third horizontal drive assembly 61. The third horizontal drive assembly 61 includes a third horizontal motor 611 mounted on the upright plate 11, a third synchronous belt device 612 mounted on the third horizontal motor 611 and the upright plate 11 opposite to the third horizontal motor 611, and a third slide rail device 613 mounted on both upright plates 11. The second synchronous belt device 513 is fixedly mounted on the upright plate 11. The running direction of the third synchronous belt device 612 is the same as the extension direction of the test strip. The test head 62 is mounted on the third slide rail device 613. A test seat 621 is provided at the bottom of the test head 62. The test seat 621 is connected to the third slide rail device 613 via a guide rail adapter plate and is locked to the third synchronous belt device 612, allowing the third horizontal drive assembly 61 to drive the third slide rail device 613 to move together. The test head 62 has a general structure and will not be described in detail here.

[0031] Multiple reset detection optocouplers 70 are respectively disposed in the reciprocating lifting and conveying component 30, the pushing component 50 and the test head component 60. By setting the reset detection optocoupler push plate accordingly, the reset detection of the above components can be realized, so as to avoid errors in the movement of each component and avoid operational errors caused by errors.

[0032] In use, the fork 52 is positioned at the beginning of the pusher groove 211 on the side away from the blank scanning area 24. The test strip is positioned with the fork 52 facing the sample dispensing area 22. The second horizontal motor 512 drives the fork 52 to push the test strip towards the sample dispensing area 22. When the test strip reaches the sample dispensing area 22, the fork 52 stops moving, and the test strip is dispensed. After the dispensing is completed, the fork 52 continues to push the test strip to the end of the pusher groove 211. At this time, the test strip is located above the first transport groove 422 of the double-sided toothed plate 40 near the pusher groove 21. The lifting motor 321 drives the double-sided toothed plate 40 to rise towards the support plate 20, so that the test strip is engaged in the transport groove 422. At this time, the fork 52 is driven to reset by the second horizontal motor 512. The horizontal motor 312 and the lifting motor 321 drive the double-sided toothed plate 40 to move one gear distance towards the blank scanning area 24, then move downwards into the support plate 20, and then move one gear distance towards the push strip groove 211. It then moves upwards to engage the test strip using the second transport groove 422, thus transporting the test strip gear by gear. The double-sided toothed plate 40 repeats this cycle. When the test strip moves from the buffer area 23 to the blank scanning area 24, the second test strip is fed to the slot 241 facing the push strip groove 211 and transported by the double-sided toothed plate 40. When the test strip completes scanning, it is pushed off the support plate 20 by the double-sided toothed plate 40, and the second test strip moves to the blank scanning area 24 for scanning. Simultaneously, the third test strip completes sample application and is pushed to the slot 241 facing the push strip groove 211, and transported by the double-sided toothed plate 40.

[0033] Compared with the prior art, the present invention provides a conveying device for urine analyzer test strips, which includes a reciprocating lifting conveying assembly 30 and a double-sided toothed plate 40 to solve the problem of slanted strips during the strip pushing process and to achieve the transport of test strips by the double-sided toothed plate 40. The transport teeth 421 and transport grooves 422 on different racks 42 of the double-sided toothed plate 40 are correspondingly arranged, and the test strip is supported and transported through the corresponding two transport grooves 422, avoiding slanted strip transport. The second push strip groove 43 overlaps with the end of the push strip groove 211 near the buffer area 23, allowing the test strip to be pushed from the push strip area 21 to the buffer area 23 and received by the double-sided toothed plate 40. Driven by the reciprocating lifting conveying assembly 30, the double-sided gear 40 moves horizontally and vertically, transporting the test strip from the buffer area 23 to the slot 241 on the side away from the push strip area 21, thus pushing the test strip out of the support plate 20.

[0034] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Any modifications, equivalent substitutions or improvements within the spirit of the present utility model are covered within the scope of the claims of the present utility model.
