It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] Example 1

[0026] Reference Figure 1-3A production device for paper-based microfluidic test strips includes a frame 1 and a top frame 2 fixed to the top of the frame 1. A support base 3 is fixed on both sides of the bottom of the frame 1. A cutting mechanism is assembled between the top frame 2 and the support base 3. The cutting mechanism includes an upper die 4, a lower die 5, and a pattern cutting protrusion 6. The upper die 4 is assembled at the bottom of the top frame 2. The lower die 5 is fixed to the top of the support base 3 by screws. The pattern cutting protrusion 6 is fixed to the bottom of the upper die 4. An outlet corresponding to the position of the pattern cutting protrusion 6 is opened on the inner side of the lower die 5. The outlet and the pattern cutting protrusion 6 are transitionally fitted. A transmission mechanism is assembled between the top frame 2 and the upper die 4. An outlet chamber is fixed at the bottom of the lower die 5 and at the position inside the support base 3. The top of the outlet chamber is connected to the outlet. The processed test strips fall into the outlet chamber through the outlet and are finally collected through a drawer on one side of the outlet chamber.

[0027] The transmission mechanism includes an L-shaped support arm 7, a guide rail 8, a motor 9, a first transmission shaft 10, and a guide assembly. L-shaped support arms 7 are fixed on both sides of the bottom of the top frame 2. A guide rail 8 is fixed at the bottom of the two L-shaped support arms 7. A motor 9 is fixed on one side of the guide rail 8. The output end of the motor 9 passes through the inside of the guide rail 8 and is fixed to the first transmission shaft 10. A guide assembly is assembled between the first transmission shaft 10 and the guide rail 8. In actual use, the test paper is laid on the lower mold 5 through two take-up rollers and slowly transmitted. Through the continuous vertical reciprocating motion of the upper mold 4, continuous processing is achieved.

[0028] The guiding assembly includes a first gear 11, a connecting rod 12, a second gear 13, a guide frame 14, and a quick-connect rod 15. One end of the first drive shaft 10 is fixed with the first gear 11. The first drive shaft 10 is positioned off-center from the center of the first gear 11. The bottom of the first gear 11 is meshed with the second gear 13. A connecting rod 12 is rotatably connected to the center of the first gear 11 and the second gear 13 via a pin. The guide frame 14 is slidably connected to the inner side of the guide rail 8 off-center from the first drive shaft 10. The guide frame 14 is assembled with the second gear 13. The bottom of the guide frame 14 is fixed with the quick-connect rod 15. The quick-connect rod 15 is assembled with the upper mold 4. When the output end of the motor 9 drives the first drive shaft 10 to rotate, the first drive shaft 10 drives the first gear 11 to rotate, enabling the first gear 11 to mesh with the second gear 13 and rotate, thus allowing the guide frame 14 to drive the quick-connect rod 15 to move vertically.

[0029] A second drive shaft 16 is fixed on one side of the guide frame 14. The second drive shaft 16 is rotatably connected to the second gear 13 and is located off the center of the second gear 13. When the second gear 13 rotates, since the second drive shaft 16 is rotatably connected to the second gear 13 and is located off the center of the second gear 13, the second gear 13 can drive the guide frame 14 to move vertically along the inner side of the guide rail 8 through the second drive shaft 16.

[0030] Example 2

[0031] Further optimizations to Example 1, specifically, such as... Figure 4 As shown, a mating mechanism is assembled between the quick-connect rod 15 and the upper mold 4. The mating mechanism is used to connect the upper mold 4 and the quick-connect rod 15.

[0032] The mating mechanism includes a second drive shaft 16, a mounting base 17, a force transmission rod 18, a connecting pull plate 19, a coupling joint 20, and a guide port 21. The mounting base 17 is fixed to the top of the upper mold 4. A guide port 21 is provided on the top of the mounting base 17, and the guide port 21 is slidably connected to the quick-connect rod 15. One end of the mounting base 17 is slidably connected to the force transmission rod 18, and one end of the force transmission rod 18 is fixed to the connecting pull plate 19. An inner cavity is provided on the inner side of the mounting base 17 near the connecting pull plate 19, and the inner cavity is slidably connected to the connecting pull plate 19. A spring is sleeved on the outer side of the force transmission rod 18, and one end of the spring is fixed to the connecting pull plate 19. The other end is fixed to the inner cavity. A connector 20 is fixed on the side of the connecting pull plate 19 away from the force transmission rod 18. The connector 20 is slidably connected to the inner cavity. A recessed part corresponding to the position of the connector 20 is opened on the outer side of the quick-connect rod 15. The recessed part is slidably connected to the connector 20. When the upper mold 4 needs to be replaced later, pull the force transmission rod 18 to compress the spring of the connecting pull plate 19 and retract it. This causes the connecting pull plate 19 to drive the connector 20 to retract into the inner cavity until the connector 20 is separated from the recessed part. Then, separate the mounting base 17 from the quick-connect rod 15 and replace the new upper mold 4. The lower mold 5 can be replaced by removing the screws.

[0033] In summary:

[0034] This utility model addresses the technical problem of the traditional test strip manufacturing process, which requires manual trimming after the test strip is drawn. This series of steps is not only cumbersome but also limits operational efficiency. The present invention employs the technical solutions described in the above embodiments. Furthermore, the implementation process of the above technical solutions is as follows:

[0035] Move the device to the designated area, then connect it to an external power source. Place the test paper on the lower mold 5, and start the motor 9. The output of the motor 9 drives the first drive shaft 10 to rotate, which in turn drives the first gear 11 to rotate. Because the first drive shaft 10 and the first gear 11 are eccentrically connected, the first gear 11 is meshed with the second gear 13, the connecting rod 12 is rotatably connected to the first gear 11 and the second gear 13, and the second drive shaft 16 is eccentrically connected to the second gear 13, the first gear 11 can mesh with the second gear 13 to rotate. Under the constraint of the sliding connection between the guide frame 14 and the guide rail 8, the guide frame 14 drives the quick-connect rod 15 to move vertically until the upper mold 4 drives the pattern cutting protrusion 6 to press the test paper onto the discharge port of the lower mold 5. At this time, the test paper, which is processed to be consistent with the outer side of the pattern cutting protrusion 6, is discharged into the discharge bin below the lower mold 5 through the discharge port, completing one processing cycle.

[0036] With the above-mentioned settings, this application will certainly solve the above-mentioned technical problems, and at the same time achieve the following technical effects:

[0037] 1. Through the structural design of the pressing and cutting mechanism and the transmission mechanism, this utility model makes it easy to press and cut the test paper on the lower mold 5, so that the pattern cutting protrusion 6 can cooperate with the discharge port, and press and cut the test paper according to the shape of the pattern cutting protrusion 6. Finally, the paper falls through the discharge port to complete the processing, which speeds up the work efficiency and improves the efficiency.

[0038] 2. Through the structural design of the cooperating mechanism and the lower mold 5, this utility model allows the device to replace different types of upper mold 4 and lower mold 5, which facilitates the processing of test papers with different shapes and is beneficial to use.
