[0033] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0034] It should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0035] The automated kit assembly equipment provided in the embodiments of this application will now be described.

[0036] Please see Figure 1 , Figure 2 This is a schematic diagram of an automated reagent kit assembly device. The automated reagent kit assembly device includes a ring guide rail module 15, and several stations arranged sequentially along the rotation direction of the ring guide rail module 15: a bottom shell loading station 1, a bottom shell direction detection station 2, a bottom shell reversing station 3, a first test strip loading station 4, a second test strip loading station 5, a test strip detection station 6, a top cover loading station 7, a top cover direction detection station 8, a top cover reversing station 9, an assembly station 10, a pressing station 11, a finished product detection station 12, a defective product rejection station 13, and a good product unloading station 14. The ring guide rail module 15 is equipped with positioning carriers 16 corresponding to each station. Please refer to [link to relevant documentation]. Figure 3 The positioning carrier 16 is provided with two alternately distributed bottom shell positioning slots 17 and two top cover positioning slots 18.

[0037] Bottom shell loading station 1 conveys the bottom shell 17 to the positioning carrier 16 on the annular guide rail module 15. Two bottom shells 17 are placed alternately on each positioning carrier 16, for example, in the second and fourth positioning slots. Bottom shell orientation detection station 2 takes pictures of the bottom shell 17 to check if its orientation is correct. Subsequently, bottom shell reversing station 3 corrects the incorrectly oriented bottom shells 17. The first test strip loading station 4 and the second test strip loading station 5 place test strips into the two bottom shells 17 respectively. The test strip detection station 6 takes pictures of the test strips to check if their position is correct and if their surface is contaminated. Those that do not meet the conditions are marked as defective. Top cover loading station 7 conveys the top cover 18 to the first and third positioning slots. Top cover orientation detection station 8 takes pictures of the top cover 18 to check if its orientation is correct. Subsequently, the top cover reversing station 9 corrects the incorrectly oriented top cover 18. The assembly station 10 places the top cover 18 onto the bottom shell 17 with the test strip installed. The pressing station 11 presses the top cover 18 to assemble it with the bottom shell 17. The finished product inspection station 12 photographs the finished product to determine if there are any impurities on the surface and whether the appearance is acceptable. The defective product rejection station 13 removes the defective products, and the good product unloading station 14 removes the qualified products from the circular guide rail module 15.

[0038] In one embodiment, the bottom shell loading station 1 and the top cover loading station 7 have the same structure and principle. Here, only the bottom shell loading station 1 will be described in detail.

[0039] Please see Figures 4-6 The bottom shell loading station 1 includes a dual-channel conveyor device 19 and a bottom shell loading robot 20. The dual-channel conveyor device 19 includes a dual-channel conveyor belt 20. A limiting cover plate 21 is provided above the discharge end of the dual-channel conveyor belt 20. The limiting cover plate 21 includes a cover plate body 22 and a front baffle plate 23 located in front of the cover plate body 22. Two first material picking ports 24 and two second blocking parts 25 are provided on the cover plate body 22 from the near end to the far end of the front baffle plate 23. Specifically, the size of the first material picking port 24 is at least large enough to allow the bottom shell loading robot 20 and the bottom shell 17 to pass through together.

[0040] During loading, several bottom shells 17 are divided into two rows and loaded sequentially along the two feed channels of the dual-feeder conveyor belt 20. The first bottom shell enters between the limiting cover plate 21 and the feed channel and is blocked by the front baffle plate 23. At this time, the first bottom shell is directly opposite the first feeding port 24 of the cover plate body 22 and can be grabbed by the bottom shell loading robot 20 and moved to the positioning carrier 16 on the annular guide rail module 15. The second bottom shell is located below the second shielding part 25. Under the obstruction of the second shielding part 25, the second bottom shell is prevented from being carried away from the feed channel by the first bottom shell.

[0041] Each side of the dual-channel conveyor belt 20 is connected to a push rod mechanism 26. The drive end of the push rod mechanism 26 can extend into the channel to push the second bottom shell 17 against the channel wall on the other side. This prevents the second bottom shell 17 from moving forward during the gripping of the first bottom shell 17, thus interfering with the gripping of the first bottom shell 17 and ensuring the normal operation of the production line. Specifically, the push rod mechanism 26 can be any device that provides a telescopic structure, such as a pneumatic push rod or an electric push rod, to provide thrust in a direction perpendicular to the conveying direction of the bottom shell 17.

[0042] In one embodiment, the second blocking portion 25 is provided with a sensing opening, and a first positioning sensor 27 is provided above the sensing opening. Specifically, the first positioning sensor 27 can be a conventional sensor such as a photoelectric switch. When the first positioning sensor 27 detects a signal from the second bottom shell, it transmits the signal to the control terminal, which then issues a command to the push rod mechanism 26 to control the push rod mechanism 26 to abut against the second bottom shell. Further, the sensing opening should be adjacent to the first material inlet 24, and may even be connected to the first material inlet 24. A second positioning sensor 28 is provided on the side of the cover plate body 22 at a position corresponding to the front end of the first material inlet 24, for detecting whether the first bottom shell is in position. Preferably, the second positioning sensor 28 can be a conventional sensor such as a fiber optic switch.

[0043] In one embodiment, the bottom shell direction detection station 2, the test strip detection station 6, the top cover direction detection station 8, and the finished product detection station 12 have the same structure, all including a detection camera and a bracket supporting the detection camera.

[0044] Please see Figure 7 The bottom shell reversing station 3 and the top cover reversing station 9 have the same structure and principle, both including two rotating gripper mechanisms 29 and a first lifting drive mechanism 30. The first lifting drive mechanism 30 drives the rotating gripper mechanism 29 to rise and fall. The rotating gripper mechanism 29 grabs the bottom shell 17 and the top cover 18 with incorrect orientation and then turns them to correct them.

[0045] The first test strip feeding station 4 and the second test strip feeding station 5 have the same structure and are used to put test strips into the two bottom shells 17 on the positioning carrier 16 respectively. Both include a test strip cutting device 31 and a test strip picking robot 32. The test strip cutting device 31 is existing technology and will not be described in detail here.

[0046] Further, please refer to Figure 8 , Figure 9 The test strip picking robot 32 includes a first lateral movement drive mechanism 33, a second lifting drive mechanism 34, a gripper mechanism 35, and a paper pressing mechanism 36. The drive end of the first lateral movement drive mechanism 33 is connected to the second lifting drive mechanism 34, and the drive end of the second lifting drive mechanism 34 is connected to a moving plate 37. For simultaneous picking of two test strips, please refer to [link to relevant documentation]. Figure 1 and Figure 2 The movable plate 37 is connected to a gripper mechanism 35 on each of its left and right sides, and the middle of the movable plate 37 is connected to a paper pressing mechanism 36. The paper pressing mechanism 36 includes a paper pressing drive mechanism 38, the drive end of which is connected to a pressure bar linkage block 39, and each end of the pressure bar linkage block 39 is connected to one end of a pressure bar plate 40. The two pressure bar plates 40 are respectively suspended between the grippers of the two gripper mechanisms 35.

[0047] Furthermore, the second lifting drive mechanism 34 drives the gripper mechanism 35 and the paper pressing mechanism 36 to move downwards, and the pressure plate 40 presses down on the test strip to prevent the test strip from flipping. The gripper mechanism 35 drives the gripper to grab the test strip, and then moves upwards under the drive of the second lifting drive mechanism 34. Under the drive of the first lateral drive mechanism 33 and the second lifting drive mechanism 34, it is transferred to the top of the bottom shell 17. The gripper mechanism 35 drives the gripper to put down the test strip, and the paper pressing drive mechanism drives the pressure plate to move downwards, pressing the test strip into the slot of the bottom shell 17 to ensure that the test strip is installed in place.

[0048] Furthermore, the pressure strip linkage block 39 includes an upper linkage block 61 and a lower linkage block 62. The upper linkage block 61 is used to connect to the drive end of the paper pressing drive mechanism 38, and the lower linkage block 62 is used to connect to the pressure strip plate 40. The lower linkage block 62 can be an integral structure or a separate structure. When separated, the two lower linkage blocks 62 are respectively connected to the two ends of the upper linkage block 61, and buffer members 63 are respectively provided between the two lower linkage blocks 62 and the upper linkage block 61 to provide buffering force to the pressure strip plate 40, avoid damage to the test strip, and facilitate individual maintenance. The buffer member 63 can be any part that can provide elastic buffering force, such as a spring, spring sheet, or rubber. Furthermore, the pressure strip plate 40 has a clearance opening at the lower center to avoid the reaction area in the middle of the test strip.

[0049] In one embodiment, the assembly station 10 includes a transverse drive mechanism, a lifting drive mechanism, and an assembly gripper mechanism, thereby driving the assembly gripper mechanism to lift and move left and right to grip the upper cover 18 and place it on the lower shell 17.

[0050] When pressing the upper cover 18 at the pressing station 11, it needs to be assembled onto the bottom shell 17. Therefore, a certain amount of pressing force is required, but the pressing speed cannot be too fast, as this can easily damage or even crack the upper cover 18 or the bottom shell 17, rendering it a defective product. Please refer to [link / reference]. Figure 10 The pressing station 11 includes a linkage rod 41, a pressing bracket 42, a lifting drive mechanism 43 located on both sides of the pressing bracket 42, and a movable pressing assembly 44. The middle part of the linkage rod 41 is provided with a fulcrum 45 biased towards the movable pressing assembly 44, and the fulcrum 45 is hinged to the pressing bracket 42. The lifting drive mechanism 43 drives one end of the linkage rod 41, and the other end of the linkage rod 41 drives the movable pressing assembly 44 to move in the opposite direction.

[0051] When pressed, the lifting drive mechanism 43 drives the linkage rod 41 to perform lever motion around the hinge fulcrum 45. The lifting drive mechanism 43 drives one end of the linkage rod 41 to move upward, and the other end of the linkage rod 41 drives the movable pressing assembly 44 to move downward. The fulcrum 45 is set close to the movable pressing assembly 44. The downward pressing speed of the movable pressing assembly 44 is less than the speed output by the driving end of the lifting drive mechanism 43, and the pressing force is greater than the force output by the driving end of the lifting drive mechanism 43.

[0052] The clamping bracket 42 includes a bracket body 46 hinged to the linkage rod 41 and a guide limiting plate 47 slidably connected to the movable clamping assembly 44. The movable clamping assembly 44 includes a lifting rod 48 slidably connected to the guide limiting plate 47, a stop block 49 connected to the upper and lower ends of the lifting rod 48 respectively, and a clamping block 50.

[0053] The end of the linkage rod 41 extends between the guide limiting plate 47 and the clamping block 50, and the end of the linkage rod 41 has a protrusion 51 facing the clamping block 50. The protrusion 51 abuts against the clamping block 50 and is used to drive the clamping block 50 to rise and fall. The linkage rod 41 and the movable clamping assembly 44 adopt a contact connection, not a rigid connection. The speed of the output force of the pressing station 11 is further reduced, and the components are less prone to wear, thus extending the service life.

[0054] Please refer to 2. Figure 11 The waste removal station 13 includes a waste bin 52, a waste-picking gripper mechanism 53, a third lifting drive mechanism 54, and a second lateral movement drive mechanism 55. The waste-picking gripper mechanism 53 is connected to the drive end of the third lifting drive mechanism 54, and the third lifting drive mechanism 54 is connected to the drive end of the second lateral movement drive mechanism 55. After the waste-picking gripper mechanism 53 picks up the waste, it throws it into the waste bin 52, completing the waste removal process.

[0055] Please see Figure 2 , Figure 12 The good product unloading station 14 includes an unloading conveyor mechanism 56, a good product gripper mechanism 57, a rotary drive mechanism 58, a fourth lifting drive mechanism 59, and a third lateral movement drive mechanism 60. The good product gripper mechanism 57 is connected to the output end of the rotary drive mechanism 58, the rotary drive mechanism 58 is connected to the drive end of the fourth lifting drive mechanism 59, and the fourth lifting drive mechanism 59 is connected to the drive end of the third lateral movement drive mechanism 60. After the good product gripper mechanism 57 picks up the good product, it rotates it and places it on the unloading conveyor mechanism 56.

[0056] Regarding the first lifting drive mechanism 30, the first lateral movement drive mechanism 33, the second lifting drive mechanism 34, the paper pressing drive mechanism 38, the lifting drive mechanism 43, the third lifting drive mechanism 54, the second lateral movement drive mechanism 55, the fourth lifting drive mechanism 59, and the third lateral movement drive mechanism 60, any drive form, such as pneumatic, electric, or hydraulic, can be selected. In one embodiment, the first lateral movement drive mechanism 33, the second lateral movement drive mechanism 55, and the third lateral movement drive mechanism 60 are selected as slide cylinders, while the first lifting drive mechanism 30, the second lifting drive mechanism 34, the paper pressing drive mechanism 38, the lifting drive mechanism 43, the third lifting drive mechanism 54, and the fourth lifting drive mechanism 59 are selected as pneumatic cylinders.

[0057] This invention enables the simultaneous processing of two reagent kits, adding workstations and reducing the number of actions at each workstation, thus significantly improving production efficiency. The invention features a ring guide rail module with the following sequentially arranged workstations: bottom shell loading station 1, bottom shell orientation detection station 2, bottom shell reversing station 3, first test strip loading station 4, second test strip loading station 5, test strip detection station 6, top cover loading station 7, top cover orientation detection station 8, top cover reversing station 9, assembly station 10, pressing station 11, finished product inspection station 12, defective product rejection station 13, and good product unloading station 14. The ring guide rail module 15 is equipped with positioning carriers 16 corresponding to each workstation. The entire production process is highly efficient and has a high yield rate. The bottom shell loading station 1 includes a dual-channel conveyor 19 and a bottom shell loading robot 20. The discharge end of the dual-channel conveyor 19 is equipped with a limiting cover 21, a first positioning sensor 27, a second positioning sensor 28, and a push rod mechanism 26, which limit the second bottom shell 17 and effectively prevent interference from the second bottom shell 17 when the first bottom shell 17 is being gripped. Finally, the assembly action is divided into an assembly station 10 and a pressing station 11. The pressing station 11 is designed using the lever principle, which ensures proper assembly and reduces the generation of defective products.

Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
