[0033] A mounting base 1 on which a vertical drive mechanism 2 and a hollow rotating mechanism 3 are fixedly mounted;

[0034] The knob holder 4 is coaxially connected to the hollow rotating mechanism 3, and the knob holder 4 is formed with an inner groove 410 for being sleeved on the rotary button 9.

[0036] See attached Figure 1 and attached Figure 2 In the above embodiment, the rotary button 9 to be tested is placed below the rotary button test module. On the one hand, during the test, the rotary button test module moves downward as a whole, the knob holder 4 approaches the rotary button 9 and the inner groove 410 is sleeved onto the rotary button 9 to achieve relative positioning with the rotary button 9, and the hollow rotating mechanism 3 drives the knob holder 4 to rotate to achieve a rotation test of the rotary button 9; on the other hand, the pressure rod 5 moves downward under the drive of the vertical driving mechanism 2 and performs a press test on the middle position of the rotary button 9. In the embodiment, the hollow rotating mechanism 3 can be a hollow rotating platform connected to a motor, and its rotation axis can pass through the central cavity of the platform, and the central cavity is used to accommodate the movable pressure rod 5. This embodiment realizes the integration of the rotation test and the press test functions, simplifies the test process, and improves the test efficiency.

[0037] See attached Figure 1 In the above embodiment, the vertical drive mechanism 2 includes a screw motor 210 fixedly mounted on the mounting base 1 and a moving block 220 connected to the screw of the screw motor 210. When the screw of the screw motor 210 rotates, the moving block 220 moves axially, and the pressure rod 5 is connected to the moving block 220. In the embodiment, the screw motor 210 is fixedly arranged, and a screw nut is provided in the moving block 220. When the screw of the screw motor 210 rotates, the moving block 220, which cooperates with it, moves up and down synchronously, and the pressure rod 5 connected to the moving block 220 also moves up and down, thereby pressing the rotation button 9.

[0038] See attached Figure 1 In the above embodiment, the mounting base 1 includes a top plate 110 and a bottom plate 120, respectively, at the upper and lower ends, and a support member 130 connected between the top plate 110 and the bottom plate 120.

In the embodiment, the support member 130 is four support rods connected between the top plate 110 and the bottom plate 120. The support rods are installed at the four corners of the top plate 110 and the bottom plate 120, while the middle position is left empty for the movable block 220. In an optional embodiment, the support member 130 can also be a support plate arranged around the edges of the top plate 110 and the bottom plate 120.

[0039] See attached Figure 1In the above embodiment, the screw motor 210 is fixedly mounted on the upper end of the top plate 110, the moving block 220 is mounted within the movable space, the screw of the screw motor 210 passes through the top plate 110 and is connected to the moving block 220, and the hollow rotating mechanism 3 is fixedly mounted on the lower end of the bottom plate 120. In this embodiment, the screw of the screw motor 210 passes through the top plate 110 and is connected to the moving block 220. When the screw motor 210 drives its screw to rotate, the moving block 220 moves up and down within the movable space within the mounting base 1, and the pressure rod 5 passes through the bottom plate 120, the hollow rotating mechanism 3, and the knob holder 4.

[0040] See attached Figure 1 In the above embodiment, a pressure sensor 6 is further connected between the vertical drive mechanism 2 and the pressure rod 5. A torque sensor 7 is further connected between the hollow rotating mechanism 3 and the knob holder 4. In this embodiment, the pressure sensor 6 is used to monitor pressure changes in real time during the compression test, and the torque sensor 7 is used to accurately measure torque during the rotation test. This not only provides accurate data for product quality assessment and helps identify potential failures of the knob 9, but also prevents damage to the knob 9 caused by excessive force applied by the vertical drive mechanism 2 or the hollow rotating mechanism 3 during the test.

The upper mold assembly 810 is relatively fixed to the mounting base 1, so that when the upper mold assembly 810 moves downward, the rotary button test module can move downward as a whole to test the rotary button 9.

[0043] See attached Figure 3 and attached Figure 4In the above embodiment, it includes a box body 8, an upper mold assembly 810 and a lower mold assembly 820 installed in the box body 8, and an operation port is provided at the front end of the box body 8. The lower mold assembly 820 is connected to a translation cylinder 830, which is used to push out or retract the lower mold assembly 820 at the operation port. In the embodiment, driven by the translation cylinder 830, the lower mold assembly 820 can be translated in and out of the operation port in a drawer-like manner. When the lower mold assembly 820 is pushed out, the rotary button 9 can be placed on the lower mold assembly 820. After the lower mold assembly 820 is retracted into the box body 8, the upper mold assembly 810 is moved down again to test the rotary button 9. In this embodiment, the test position on the lower mold assembly 820 can hold multiple rotary buttons 9. Correspondingly, multiple rotary button test modules are fixed on the upper mold assembly 810, so that multiple rotary buttons 9 can be tested at one time, thereby improving the testing efficiency.
