[0002] As the core component of motor or vibration electronic products, the motor provides power and vibration transmission for the products. In the production process of the vibration motor of such electronic products, it is of utmost importance to ensure the stability of the motor transmission. The stability of the motor transmission directly affects the use experience of electronic products, and then affects its sales volume. Therefore, the vibration motor of electronic products must be tested for stability during the production process, and one of the key factors affecting the transmission stability is the gear backlash. The existing technology generally uses the lead pressing method, the feeler gauge method, and the dial indicator for testing. Such testing methods are cumbersome and require a lot of manpower and time; or optical measurement methods are used. Such equipment is expensive and complicated to operate, and is not suitable for large-scale testing using acceleration sensors for collection; and the switching operation of motors of different models or sizes is relatively cumbersome, and multiple sets of operating machines need to be set up, which is costly. If a gear backlash detection device with a simple structure can be designed, which measures the return angle of the gear meshing through an angular velocity sensor to calculate the gear backlash, can quickly replace the motor, and can adapt to motor products of different sizes, the above problems can be solved.

[0012] like Figures 1 to 5As shown, in this embodiment, the present invention includes a base plate 1 and a clamping module 2, the clamping module 2 is connected to one end of the base plate 1 through a dual-axis adjustment module 3, and a test module 4 is provided at the other end of the base plate 1, the test module 4 includes a test base 41, a propulsion module 42 and a stepper motor 43, the stepper motor 43 is connected to the active end of the propulsion module 42, and the active end of the stepper motor 43 cooperates with the gear end of the motor product 6 on the clamping module 2 through an angle sensor 5. It can be seen that the motor product 6 is fixed by the clamping module 2, and the loading module 2 has a fixed shaft, and the planetary wheel of the motor is fixed by the fixed shaft; then the drive shaft is connected to the sun gear; the drive shaft is connected to the angle sensor 5. During the test, the stepper motor 43 first rotates forward to stall, the angle sensor 5 is reset, and then reversed to stall, and then the angle sensor can read the return angle α during the gear meshing process. The formula: α / 360*d1 (gear pitch circle diameter) can be used to measure the gear meshing backlash, the structure is simple, and the measurement accuracy is high.

[0013] like Figure 1 and Figure 4 As shown, in this embodiment, the clamping module 2 includes a carrier 21 and a flip module 22. The upper end surface of the carrier 21 is provided with a contoured groove adapted to the motor product 6. The flip module 22 is hinged to the carrier 21 and matched with the motor product 6 on the contoured groove. It can be seen that the flip module 22 can realize the rapid clamping and replacement of the same motor product 6 without replacing the entire module, which is more efficient.

[0014] like Figure 1 and Figure 3 As shown, in this embodiment, the dual-axis adjustment module 3 includes an X-axis adjustment module 31 and a Z-axis adjustment module 32. The X-axis adjustment module 31 is connected to one end of the upper end surface of the base plate 1, and the Z-axis adjustment module 32 is connected to the movable end of the X-axis adjustment module 31. The lower end surface of the carrier 21 is connected to the movable end of the Z-axis adjustment module 32. It can be seen that the clamping module 2 is placed in the dual-axis displacement adjustment module, and by adjusting the X-axis adjustment module 31 and the Z-axis adjustment module 32, the motor product 6 can be completely aligned with the second coupling 8 to prevent the eccentricity of the two axes from causing the loss of driving power.

[0015] like Figures 1 to 3As shown, in this embodiment, the propulsion module 42 is arranged in the middle of the test base 41, and a plurality of slide rail modules 44 are arranged on both sides of the test base 41. A support plate 45 is arranged at the movable end of the propulsion module 42, and the support plate 45 is connected to the movable ends of the plurality of slide rail modules 44. The propulsion module 42 drives the support plate 45 to slide with the test base 41. It can be seen that the propulsion module 42 controls the support plate 45, and then drives the second coupling 8 (connected to the drive shaft of the motor product 6). After the modules are integrated and connected, the test can be started.

[0016] like Figures 1 to 3 As shown, in this embodiment, the stepper motor 43 is arranged on the support plate 45, the angle sensor 5 is arranged on the upper end surface of the support plate 45 close to one end of the clamping module 2, the stepper motor 43 is rotationally matched with the corresponding end of the angle sensor 5 through the first coupling 7, and the other end of the angle sensor 5 is rotationally matched with the driving end of the motor product 6 on the clamping module 2 through the second coupling 8. It can be seen that the rotation end of the angle sensor 5 and the rotation end of the stepper motor 43 are concentrically arranged, which can ensure that the rotation force of the support plate 45 is uniform during the movement and testing process, and the integrated connection of the module is realized by docking the second coupling 8 with the motor product 6, which can be memorized for power-on detection.

[0017] like Figure 1 and Figure 2 As shown, in this embodiment, a plurality of sensors 9 are arranged on one side of the bottom plate 1, and a sensing baffle 10 is arranged on the side of the support plate 45 corresponding to the plurality of sensors 9, and the sensing baffle 10 is inductively matched with the plurality of sensors 9. It can be seen that the sensing baffle 10 and the plurality of sensors 9 can cooperate to control the moving distance of the support plate 45, and prevent the second coupling 8 from overpressing the motor product 6 and causing damage.

[0018] The working principle of the present invention is as follows: before the equipment is started, the propulsion module 42 drives the support plate 45 to be located in the buffer position, the flip module 22 is opened, the motor product 6 to be tested is placed on the carrier 6, and then the flip module 22 and the motor product 6 are pressed and fixed, and the connection end of the motor product 6 is concentrically set with the second coupling 8 through the dual-axis adjustment module 3. After the equipment is started, the propulsion module 42 drives the support plate 45 to approach the motor product 6, and the driving shaft of the motor product 6 contacts and completes the docking with the second coupling 8. After the docking is completed, the stepper motor 43 first rotates forward to stall, the angle sensor 5 is reset, and then reversed to stall, and then the angle sensor can read the return angle α during the gear meshing process. The gear meshing backlash can be measured by the formula: α / 360*d1 (gear pitch circle diameter). After the test is completed, the propulsion module 42 is reset, and the motor product 6 to be tested is replaced. The above steps are repeated to achieve rapid clamping of the motor product 6 and accurate detection of gear backlash.

[0019] Although the embodiments of the present invention are described with practical solutions, they do not constitute limitations on the meaning of the present invention. For those skilled in the art, it is obvious to modify the implementation scheme and combine it with other solutions based on this description.
