[0002] In the field of medical testing, test strip application is a crucial step in ensuring the accuracy and stability of testing. Traditional methods rely on manual operation, resulting in low efficiency. Existing technologies are increasingly adopting automated application methods to improve the efficiency of test strip application. For example, a published patent with authorization announcement number CN220841445U, entitled "A Film Application Mechanism," includes: a support base, a feeding mechanism, and a pressing mechanism. The feeding mechanism is mounted on the support base and includes multiple rollers for conveying the protective film. The pressing mechanism includes a support arm, a lower mold, an upper mold, a transverse plate, and a cylinder. The support arm is fixed to the support base, the lower mold is fixed to the support arm, and the lower mold has several mounting slots for installing test strips. The transverse plate is fixed to the top of the support arm, and the cylinder is mounted on the transverse plate. The upper mold is mounted on the piston rod of the cylinder and is used to press the protective film onto the test strip. While this solution enables automated film application to the test strips, the lower mold requires manual, repeated pulling and retraction for loading and unloading, resulting in cumbersome procedures. Furthermore, manual adjustment of the lower mold poses safety hazards. Therefore, a new technical solution is needed to simplify the operation while improving safety. Utility Model Content

The material roller 21 is mounted on the base plate 27 via a mounting base 33. The film 22 in the feeding roll 28 is conveyed to the take-up roll 29 via the material roller 21.

[0032] The membrane feeding assembly 11 in this solution is existing technology, wherein the take-up drum 29 is driven by a motor.

[0033] As one embodiment of this invention, the mounting base 33 is provided with a notch for the mounting platform 14 to pass through, and the end of the mounting platform 14 is fixed to the base plate 27 by a support plate.

[0034] The material loading station is located at the end of the installation platform 14 that is furthest from the drive component 15.

[0036] The elastic element includes a spring 39 and a guide rod 16. The top of the guide rod 16 is fixed on the pressure plate portion 20. The guide rod 16 is slidably disposed in the clearance hole of the step portion 34 in the vertical direction. The spring 39 is sleeved on the outer periphery of the guide rod 16 and is located between the pressure plate portion 20 and the step portion 34.

[0037] In one embodiment of this invention, the pressing assembly 13 further includes a mounting plate 35, which is fixed to the stepped portion 34 by a support rod 36. A cylinder 37 is mounted on the mounting plate 35, and the piston rod of the cylinder 37 is used to drive the pressing plate portion 20 to move in the vertical direction. In another embodiment of this invention, the bottom surface of the pressing plate portion 20 has a stamping block 38.

[0038] The stamping block 38 is located directly above the test strip groove 19. The stamping block 38 can be pressed into the test strip groove 19, and at the same time, the bottom edge of the stamping block 38 can cut the membrane 22.
