[0032] like Figure 1 As shown, the disc-type drug dispensing device lever torque test fixture further includes a limiting bolt 17, a hollow groove 16 is provided on the first connecting member 7, and the second connecting member 8 is slidably arranged in the hollow groove 16. A limiting groove is provided on the side of the first connecting member 7, and the limiting bolt 17 is slidably arranged in the limiting groove. When the position of the second connecting member 8 in the hollow groove 16 is determined, the limiting bolt 17 is tightened to limit the second connecting member 8 to be installed in the hollow groove 16. In one embodiment of the present invention, the relative position between the second connecting member 8 and the snap module 6 and the disc-type drug dispensing device can be adjusted by sliding the second connecting member 8 in the hollow groove 16 in the first connecting member 7, so that the disc-type drug dispensing device can be more conveniently installed on the snap module 6, thereby improving the installation and operation convenience of the disc-type drug dispensing device lever torque test fixture.
[0033] like Figure 1 As shown, the central axis fixing fixture 3 includes a first fixing member 18 and a second fixing member 19 connected vertically. The first fixing member 18 is mounted on the first mounting post 13, and the second fixing member 19 is mounted on the second mounting post 14. The third end 20 is the vertical connection point between the first fixing member 18 and the second fixing member 19. In one embodiment of the present invention, the first mounting post 13, the second mounting post 14 and the center of the disc-type dispenser are arranged in a triangle. The first end and the second end of the central axis fixing fixture 3 are respectively mounted on the first mounting post 13 and the second mounting post 14, and the third end 20 abuts against the center of the disc-type dispenser, thereby further firmly mounting the disc-type dispenser on the base plate 9 and improving the structural stability of the disc-type dispenser lever torque test fixture.
[0034] like Figure 4 and Figure 5 As shown, the snap module 6 includes a main board 21, a baffle 22, a fixing screw 23, an abutting screw 24, and a steel wire 25. The fixing screw 23 passes through the main board 21 and the baffle 22 in sequence. The abutting screw 24 passes through the baffle 22 and abuts against the side of the main board 21 facing the baffle 22, so that the baffle 22 is installed at an angle on the main board 21. The two ends of the steel wire 25 pass through the lower end of the baffle 22 and the lower end of the main body in sequence, so that the steel wire 25 and the side of the baffle 22 facing away from the main board 21 form a snap-fitting cavity. The steel wire 25 can be retracted at the lower end of the baffle 22 and the lower end of the main board 21, so that the size of the snap-fitting cavity can be adjusted, and the lever 28 is snapped into the snap-fitting cavity. In one embodiment of the present invention, the size of the snap-fitting cavity is adjusted by adjusting the retraction of the two ends of the steel wire 25, thereby allowing the snap-fitting cavity to firmly engage the lever 28, thereby improving the structural stability of the disc-type dispenser lever torque test fixture.

In one embodiment of the present invention, the lower end of the lever 28 can be well abutted against the side of the lever 28, so that the baffle 22 can effectively drive the lever 28 to move, thereby improving the structural stability of the disc-type drug delivery device lever torque test fixture.
[0036] In one embodiment of the present invention, the angle of inclination between the baffle 22 and the main plate 21 is 0 to 15 degrees. This inclination angle further enables the curved surface 26 at the lower end of the baffle 22 to better fit the curved pressing surface 27 of the lever 28, further improving the structural stability of the disc dispenser lever torque test fixture.
[0037] In one embodiment of the present invention, the arc surface 26 has an arc angle of 0 to 5°, which can further enable the arc surface 26 at the lower end of the baffle 22 to fit more closely on the arc-shaped pressing surface 27 of the lever 28, thereby further improving the structural stability of the disc-type drug dispenser lever torque test fixture.
[0038] like Figure 1 As shown, the first fixing module 4 and the second fixing module 15 are both hexagonal. The hexagonal structure of the first fixing module 4 and the second fixing module 15 can achieve a more stable installation with the torsion testing machine, improving the installation convenience of the disc-type drug delivery device lever torque test fixture.
[0039] like Figures 1 to 6 As shown, based on the same inventive concept, an embodiment of the present invention further provides a method for testing the torque of a disc-type drug dispensing device lever, and uses a disc-type drug dispensing device lever torque test fixture to perform a torque test on the lever 28 on the side of the disc-type drug dispensing device, comprising the following steps: Step 1, the disc-type drug dispensing device lever torque test fixture comprises a first component 1 for moving the disc-type drug dispensing device lever 28, a second component 2 for fixing the disc-type drug dispensing device and a central axis fixing fixture 3, the first component 1 comprises a first fixing module 4, a robotic arm 5 and a snap module 6, the robotic arm 5 comprises a first connecting member 7 and a second connecting member 8 connected vertically, one end of the second connecting member 8 is slidably mounted on one end of the first connecting member 7, the other end of the second connecting member 8 is detachably mounted on the snap module 6, the other end of the first connecting member 7 is mounted on one end of the first fixing module 4, and the other end of the first fixing module 4 is used to be detachably mounted on the main unit 29 of the torsion testing machine; the snap module 6 comprises a snap connection cavity, The clamping cavity is used to clamp the shift rod 28; the second component 2 includes a base plate 9, a first fixing column 10, a second fixing column 11, a third fixing column 12, a first mounting column 13, a second mounting column 14 and a second fixing module 15. The first fixing column 10, the second fixing column 11 and the third fixing column 12 are arranged in a triangle on the base plate 9 and are all used to clamp the side of the disc-type dispenser. The first mounting column 13 and the second mounting column 14 are both installed on the base plate 9 and form a triangular arrangement with the center of the disc-type dispenser. The central axis fixing fixture 3 includes a first end, a second end and a third end 20 arranged in a triangle. The first end is installed on the first mounting column 13, the second end is installed on the second mounting column 14, and the third end 20 is abutted against the center of the disc-type dispenser for pressing the upper cover surface of the disc-type dispenser. A clamping groove is provided on the base plate 9 for clamping at the center of the disc-type dispenser. The second fixing module 15 is used to be detachably mounted on the support of the torsion testing machine;
[0040] Step 2. After the disc dispenser lever torque test fixture is installed between the disc dispenser and the torsion testing machine according to step 1, use the torsion testing machine and its built-in test software to perform a torque test on the lever 28. Set the test software to set the initial position parameters, control speed value, number of cycles, and displacement value of the lever 28. When the lever 28 fully opens the blister, it pauses for 0 to 5 seconds. After the lever 28 returns to the initial position, it pauses for 0 to 2 seconds. Adjust the production and assembly parameters of the disc dispenser according to the torque test results until they meet the production quality standards. During the production process, the disc dispenser is subjected to random inspections of the torque test of the lever 28 so that the production and assembly parameters can be adjusted at any time.
[0041] In one embodiment of the present invention, in step 2, the initial position parameter of the lever 28 is set to 30° to 50°, the control speed value is set to 2000° to 2500° / min, the number of cycles is set to 60, and the displacement value of the lever 28 is set to 0° to 10°. Preferably, the initial position parameter of the lever 28 is set to 44°, the control speed value is set to 2100° / min, and the displacement value of the lever 28 is set to 8.5°. The setting parameters within the above range can more accurately test the torque required to move the lever 28, thereby improving the test accuracy of the disc-type drug delivery device lever torque test method.
[0042] In one embodiment of the present invention, the torque required to open the blister of the disc dispenser when the production and assembly parameters of the disc dispenser are adjusted and when the production and assembly parameters of the disc dispenser are not adjusted are compared. The comparison results are as follows: Figure 7 As shown, it can be seen from the comparison results that: after the torque test, the disc dispenser whose production and assembly parameters were adjusted has a smaller and more stable force for opening the blisters, and the force value does not change significantly with the increase in the number of opened blisters. However, in the disc dispenser whose production and assembly parameters are not adjusted, the disc dispenser has a larger force for opening the blisters, and starting from the blister in the middle, the force required for opening becomes unstable, and the force value increases significantly with the increase in the number of opened blisters.
