Description

Technical Field

[0001] This utility model relates to the field of urine dry chemical analysis and detection technology, and in particular to a test strip transfer device that is easy to disassemble and assemble. Background Technology

[0002] The urine dry chemistry analysis and testing device uses a sampling dropper to sequentially drop urine samples onto dry chemistry test strips. The test strips are then transported to the CIS detection and scanning position via a test strip transport belt. The CIS scanner determines the concentration of corresponding substances in the urine by scanning and observing the color changes of the test strip's drug block, thereby enabling clinical testing and diagnosis.

[0003] The existing test strip transport belt device has the following structural issues:

[0004] During sample application and transportation, test strips may experience sample overload or spillage. Over time, this can lead to dirt and urine buildup on the test strip's transport belt, causing the test strip to become skewed, have a relatively low level, and result in abnormal sample detection. To address these issues, the transport belt is typically cleaned or replaced periodically. However, the current cantilevered circular pulley structure and limited instrument space significantly reduce the ease of maintenance for the transport belt. Utility Model Content

[0005] The purpose of this invention is to provide a test strip transmission device that is easy to disassemble and assemble, aiming to improve the convenience of cleaning and replacing the transmission belt of traditional test strip transmission devices.

[0006] To achieve the above objectives, this utility model provides a test strip transport device that is easy to disassemble and assemble, including a test strip transport belt, a guide mechanism, a CIS detector, a sample dispensing lever mechanism, and a drive mechanism. The test strip transport belt is disposed on one side of the guide mechanism. The CIS detector is fixedly connected to the guide mechanism and located at the top of the guide mechanism. The sample dispensing lever mechanism is assembled on the side of the test strip transport belt near the test strip transport belt. The drive mechanism is assembled on one side of the guide mechanism. The test strip transport belt includes a driving pulley, a driven pulley, a gear, a connecting frame, a transport belt body, a first bearing, a second bearing, a fixing plate, and a first fastening screw. The connecting frame is connected to the guide mechanism. The guide mechanism is slidably connected and located on one side of the guide mechanism. The first bearing is rotatably connected to the connecting frame and located on one side of the connecting frame. The driving pulley is mounted on the outside of the first bearing. The second bearing is rotatably connected to the connecting frame and located on the side of the connecting frame away from the first bearing. The driven pulley is mounted on the outside of the second bearing. The conveyor belt body is sleeved on the outside of the driving pulley and the driven pulley. The gear is fixedly connected to the driving pulley and located on one side of the driving pulley. The fixing plate is disposed on the guide mechanism near the driving pulley. The first fastening screw is threadedly connected to the fixing plate and fixed on the guide mechanism.

[0007] The driving mechanism includes a drive motor and a drive wheel. The drive motor is fixedly connected to the guide mechanism and is located on one side of the guide mechanism. The drive wheel is fixedly connected to the output end of the drive motor and meshes with the gear, and is located on one side of the gear.

[0008] The guiding mechanism includes a first guide support plate, a second guide support plate, a base plate, and a third fastening screw. The first guide support plate is fixedly connected to the drive motor and is located on one side of the drive motor. The base plate is disposed at the bottom of the first guide support plate. The second guide support plate is disposed on the side of the second guide support plate away from the first guide support plate. The third fastening screw is respectively assembled on both sides of the base plate.

The point contact method is cleverly used to achieve precise positioning. The back of the connecting frame is fastened to the guide mechanism by the fixing plate and the first fastening screw. When the drive mechanism is operating, it drives the gear to rotate. The rotation of the gear drives the active pulley to rotate. The tension force generated between the active pulley and the driven pulley of the transport belt body generates friction force, thereby driving the driven pulley to rotate together, forming the test strip transport belt. The test strip is transported by belt conveyor. When the test strip transport belt is disassembled for maintenance, it is only necessary to remove the fixing plate and the first fastening screw, and then pull the connecting frame out of the guide mechanism to clean and replace the transport belt body on the connecting frame.

The test strip transport belt 100 is disposed on one side of the guide mechanism 200. The CIS detector 300 is fixedly connected to the guide mechanism 200 and located at the top of the guide mechanism 200. The sample dispensing lever mechanism 400 is assembled on the side of the test strip transport belt 100 near the test strip transport belt 100. The drive mechanism 500 is assembled on one side of the guide mechanism 200. The test strip transport belt 100 includes a driving pulley 101, a driven pulley 102, a gear 103, a connecting frame 104, a transport belt body 105, a first bearing 106, a second bearing 107, a fixing plate 108, and a first fastening screw 109. The connecting frame 104 is connected to the guide mechanism 200. The guide mechanism 200 is slidably connected and located on one side of the guide mechanism 200. The first bearing 106 is rotatably connected to the connecting frame 104 and located on one side of the connecting frame 104. The driving pulley 101 is mounted on the outside of the first bearing 106. The second bearing 107 is rotatably connected to the connecting frame 104 and located on the side of the connecting frame 104 away from the first bearing 106. The driven pulley 102 is mounted on the outside of the second bearing 107. The conveyor belt body 105 is sleeved on the outside of the driving pulley 101 and the driven pulley 102.

When the drive mechanism 500 operates, it drives the gear 103 to rotate, and the rotation of the gear 103 drives the drive pulley 101 to rotate, while the conveyor belt body... The tension force generated between the driving pulley 101 and the driven pulley 102 creates friction, thereby driving the driven pulley 102 to rotate together, forming the test strip transport belt 100. The test strip is transported by belt conveyor. When the test strip transport belt 100 is disassembled for maintenance, only the fixing plate 108 and the first fastening screw 109 need to be removed, and then the connecting frame 104 needs to be pulled out of the guide mechanism 200. The transport belt body 105 on the connecting frame 104 can then be cleaned and replaced. This test strip delivery device is an improvement on the existing product structure, focusing on refining the structural mechanism of the dry chemical test strip during transport on the conveyor belt. It improves the ease of cleaning and maintenance of the conveyor belt compared to traditional test strip delivery devices; enhances the stability of the test strip during transport, reducing the risks associated with its transmission; and ensures the relative horizontality of the test strip and the CIS detector 300, improving the accuracy and stability of the test strip detection.

[0024] In this embodiment of the utility model, the drive motor 501 is controlled by a controller to drive the drive wheel 502 to rotate. The rotation of the drive wheel 502 drives the gear 103 to rotate, and the rotation of the gear 103 drives the drive pulley 101 to rotate. The tension force generated between the drive pulley 101 and the driven pulley 102 by the transmission belt body 105 generates friction force, thereby driving the driven pulley 102 to rotate together.

[0025] Furthermore, the guiding mechanism 200 includes a first guiding support plate 201, a second guiding support plate 202, a base plate 203, and a third fastening screw 204.

The base plate 203 is disposed at the bottom of the first guiding support plate 201. The second guiding support plate 202 is disposed on the side of the second guiding support plate 202 away from the first guiding support plate 201. The third fastening screw 204 is respectively assembled on both sides of the base plate 203. Both the first guiding support plate 201 and the second guiding support plate 202 have guide grooves 205, which are located on the side of the first guiding support plate 201 and the second guiding support plate 202 closer to the connecting frame 104.

[0026] In this embodiment of the invention, the first guide support plate 201 and the second guide support plate 202 are assembled onto the base plate 203 by the third fastening screw 204, providing support and installation conditions for the test strip conveyor belt 100, the CIS detector 300, the sample dispensing lever mechanism 400, and the driving mechanism 500.

The first guide support plate 201, the second guide support plate 202, and the test strip conveyor belt 100 form a gantry structure, which effectively solves the problem of imbalance and vibration caused by excessively long cantilever structures, thus improving the stability and reliability of the test strip during transportation. The first guide support plate 201 and the second guide support plate 202, together with the test strip conveyor belt 100, form a gantry structure, which effectively solves the problem of imbalance and vibration caused by excessively long cantilever structures, thus improving the stability of the test strip during transportation.

[0027] Furthermore, the connecting frame 104 includes a second fastening screw 110, a pin 111, a first connecting block 112, a second connecting block 113, and a third connecting block 114.

The third connecting block 114 is disposed between the first connecting block 112 and the second connecting block 113. The second fastening screw 110 and the pin 111 are assembled on the third connecting block 114.

[0028] In this embodiment of the utility model, the third connecting block 114 is assembled between the first connecting block 112 and the second connecting block 113 by the second fastening screw 110 and the pin 111. The first bearing 106 and the second bearing 107 are assembled between the first connecting block 112 and the second connecting block 113. The front ends of the first connecting block 112 and the second connecting block 113 are rounded, which serves as a guide and positioning function. The test strip conveyor belt 100 provides horizontal guidance and positioning functions, and forms point contact with the rounded front ends of the first connecting block 112 and the second connecting block 113 to achieve precise positioning.

[0029] The present invention discloses a functional installation process for a test strip transport device that is easy to disassemble and assemble: The test strip transport belt 100 is pushed into the guide grooves 205 on the first guide support plate 201 and the second guide support plate 202 of the guide mechanism 200, so that the rounded corners of the top ends of the first connecting block 112 and the second connecting block 113 respectively reach point contact with the first guide support plate 201 and the second guide support plate 202. The point contact method is cleverly used to achieve precise positioning, and it can be fastened by the fixing plate 108 and the first fastening screw 109; When the drive motor 501 rotates, the gear 103 drives the gear 103 to rotate, and the active circular pulley 101 rotates accordingly. Then, the tension force generated between the active circular pulley 101 and the driven circular pulley 102 by the transport belt body 105 generates friction force to drive the driven circular pulley 102 to rotate together, forming a belt conveyor system, and realizing the transport of test strips by belt conveyor. The disassembly and maintenance of the conveyor belt body 105 only requires removing the fixing plate 108 and the first fastening screw 109 on the back of the paper strip conveyor belt, and pulling out the test strip conveyor belt 100 along the guide groove 205 on the first guide support plate 201 and the second guide support plate 202 to clean and replace the conveyor belt body 105.
