Description

Technical Field

[0002] During the production and assembly of various electronic devices, each component needs to be inspected before leaving the factory to meet the product's usage requirements. For motor products, performance testing is required after production is completed, such as the noise and torque generated when the motor is running. Through performance testing, the noise and torque of the motor are tested to meet the factory requirements. During the testing process, the motor needs to be clamped and then tested for noise and torque. The existing technology generally uses screws, magnetic suction or pressure arm structures to fix the motor. This fixing method is very time-consuming and causes unnecessary cost waste. The test fixation technology generally uses traditional screw fixing fixtures. Although this method is reliable and stable, the operation time is very long. If the output demand is large, it is very time-consuming and labor-intensive, and there is also the risk of not being able to lock tightly, causing test failure. If a motor noise and torque testing device with a simple structure, automatic guidance, precise limit, and multi-station noise and torque compatibility testing can be designed, the above problems can be solved.

[0020] like Figures 1 to 3As shown, in this embodiment, the fixture connection assembly 2 includes a fixture support plate 21 and a plurality of fixture modules 22, the fixture module 22 includes a fixture body 221 and a PCBA board 222, the upper end surface of the PCBA board 222 is connected to the lower end surface of the fixture body 221 through a needle block 23, a flip cover 24 is movably connected to one side of the upper end surface of the fixture body 221, a buckle 25 is provided at the locking end of the flip cover 24, and a buckle base 26 is also provided on one side of the upper end surface of the fixture body 221, and the buckle 25 and the buckle base 26 cooperate. It can be seen that the flip cover 24 and the buckle 25 cooperate to clamp and lock the motor 7, ensuring that the motor does not deviate during the detection process, and transmit the signal to other mechanisms through the PCBA board 222.

[0021] like Figure 3 As shown, in this embodiment, the flip cover 24 and the clamp body 221 are respectively provided with a first fixing groove 27 and a second fixing groove 28, and the motor 7 is limitedly matched with the first fixing groove 27 and the second fixing groove 28. It can be seen that the first fixing groove 27 and the second fixing groove 28 are adapted to the appearance of the motor 7, and the motor 7 will not be over-pressed during the clamping process, so that the detection result is more accurate.

[0022] like Figure 3 As shown, in this embodiment, the second fixing groove 28 cooperates with the needle block 23, the motor 7 connection end is connected to the needle block 23 through the second fixing groove 28, and the first fixing groove 27 and the second fixing groove 28 are both provided with a buffer rubber layer.

[0023] like Figure 1 and Figure 4 As shown, in this embodiment, the carrier connection assembly 3 includes a connection base plate 31 and a plurality of magnetic connectors 32. The lower end surface of the connection base plate 31 is connected to the movable end of the cylinder unit 4 and the movable ends of the plurality of slide rail modules 5. The fixture support plate 21 is provided with a plurality of fixture openings 29. The lower end surface connection ends of the plurality of PCBA boards 222 are connected to the plurality of magnetic connectors 32 through the plurality of fixture openings 29. It can be seen that the magnetic connector 32 is in a floating state. During the test, it can automatically mate with the female magnetic connector on the lower end surface of the PCBA board 222 by magnetic force to conduct the signal. After the test, when the fixture is unplugged, the magnetic connector 32 will not be taken away.

[0024] like Figure 1 and Figure 4 As shown, in this embodiment, the upper end surface of the connecting bottom plate 31 is provided with a plurality of positioning pins 9, and the plurality of positioning pins 9 are limitedly matched with the lower end surface of the clamp support plate 21.

[0026] like Figure 1 and Figure 2 As shown, in this embodiment, the movable end of the hysteresis brake 6 is connected to the movable end of the motor 7 through a coupling 11. It can be seen that the coupling 11 can make the motor 7 and the hysteresis brake 6 more stably connected.

[0027] like Figure 1 and Figure 2 As shown, in this embodiment, both ends of the upper end surface of the connecting bottom plate 31 are provided with handrails 12. It can be seen that the handrails 12 can be used with an external assembly line for loading and unloading, making the handling process more convenient and more efficient.

It can be seen that the MIC module 8 is used to collect the noise of the motor 7 when it is running.

After the fixing is completed, the clamp connection assembly 2 with the motor 7 installed is slowly lowered with the magnet facing downward. At this time, relying on the magnetic force of the magnet 10 and the positioning pins 9, the clamp connection assembly 2 is very smoothly connected to the carrier connection assembly 3. Due to the magnetic attraction, the clamp module 22 is in it. The parts are fixed very stably. When the equipment is started, the cylinder 4 will move forward to drive the entire test module to the detection position. The rotating end of the motor 7 is connected to the coupling 11 and then to the hysteresis brake 6. At this time, the motors 7 are powered on, and the motor 7 rotates to drive the hysteresis brake 6 to operate. At this time, the hysteresis brake 6 can both input a certain torque to the motor 7 and feedback the torque of the motor 7 to achieve the test purpose. During the operation of the motors 7, the MIC modules 8 collect noise and transmit the signal to the external detection mechanism. After the detection is completed, the cylinder 4 drives the fixture connection assembly 2 to return to the initial position, and the fixture connection assembly 2 is taken out. The above steps are repeated to complete the noise and torque test of the motor.

[0030] 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.
