[0002] In the field of automated motor testing, the coordination between the test base and the power supply structure is the core element for achieving continuous testing. Currently, motor testing power supplies often use fixed wiring or single-plug-in methods. Therefore, when the motor is moved between different testing stations, repeated wiring / power disconnection is required, leading to interruptions in the testing process and low efficiency. Utility Model Content

Multiple power supply rails are arranged along the width of the machine and set along the length of the machine. The lower surface of the test base is provided with conductive wheels that match the power supply rails. When the test base moves with the sprocket circulation mechanism, the conductive wheels contact the power supply rails to conduct electricity. The power supply rail is divided into multiple sections along the length of the machine, with each section connected end to end. Each section is connected to a different test power supply module to meet the power supply requirements of the motor at different testing stations.

[0005] According to one embodiment of the present invention, the number of conductive wheels is the same as the number of power supply rails, and they are arranged along the width of the machine platform, with each power supply rail corresponding to a set of conductive wheels in contact.

[0014] The following drawings will disclose several embodiments of this utility model. For clarity, many practical details will be described in the following description. However, it should be understood that these practical details should not be used to limit this utility model. That is, in some embodiments of this utility model, these practical details are not essential.

They are merely used to distinguish components or operations described with the same technical terms and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of various embodiments can be combined with each other, but only if they are feasible for those skilled in the art.

[0016] See Figure 1 , Figure 1 This is one of the structural diagrams of the continuous power supply structure for motor testing. Figure 2 This is the second schematic diagram of the cyclic power supply structure for continuous testing of motors during implementation. Figure 3 This is a schematic diagram of the test base structure in the embodiment. Figure 4This is a schematic diagram of the power supply rail structure in the embodiment. The continuous testing and cyclic power supply structure for a motor in this example includes a machine base 1 and a cyclic testing system 2. The cyclic testing system 2 is mounted on the machine base 1 and includes a sprocket circulation mechanism 21, multiple test bases 22, and multiple sets of power supply rails 23. The sprocket circulation mechanism 21 is arranged around the upper and lower surfaces of the machine base 1 to form a closed-loop transmission path. The multiple test bases 22 are sequentially connected along the circulation direction of the sprocket circulation mechanism 21 and move with it. The multiple sets of power supply rails 23 are arranged along the width direction of the machine base 1 and along its length direction. The lower surface of the test base 22 is provided with conductive wheels 221 that match the power supply rails 23. When the test base 22 moves with the sprocket circulation mechanism 21, the conductive wheels 221 contact and conduct with the power supply rails 23 to obtain power. The power supply rails 23 are divided into multiple sections of rail body 231 connected end-to-end along the length direction of the machine base 1. Each section of rail body 231 is connected to a different test power supply module to adapt to the power supply requirements of the motor at different testing positions. During operation, the motor is placed on the test base 22 and powered by the conductive wheel 221. It can be understood that when the test base 22 is located on different rails 231, the test base 22 is connected to test power supply modules with different functions to complete different test functions. In this way, not only can the continuity of power supply for each station be achieved, but also the power supply for each station can be set independently and without affecting each other. Therefore, multiple test stations with different functions can be set up for continuous testing, which greatly improves the testing efficiency of the motor.

[0017] Furthermore, the test base 22 includes a support plate 222, a fixed base 223, and a wire clamp 224. Multiple conductive wheels 221 are disposed on the lower surface of the support plate 222, the fixed base 223 is disposed on the upper surface of the support plate 222 for fixing the motor under test, and the wire clamp 224 is disposed at one end of the fixed base 223 near the outside of the machine base 1 and is electrically connected to the conductive wheels 221 for clamping the motor wires to achieve the connection between the motor and the power supply rail 23.

[0018] The support plate 222 is also equipped with a starting capacitor and a push switch 2221. The starting capacitor is located at the bottom of the support plate 222, and the push switch 2221 is located at one end of the fixed base 223 facing away from the wiring clamp 224. When the motor under test is installed on the fixed base, the starting capacitor, the push switch, and the motor under test are electrically connected to each other. The starting capacitor is used for the normal operation of the motor.

[0019] In this example, the machine platform is equipped with a noise detection mechanism 3, a withstand voltage detection mechanism 4, and a turn spacing detection mechanism in sequence along the movement direction of the test base. The noise detection mechanism 3 is located above the first section of the rail and is responsible for power supply and testing for noise testing. The withstand voltage detection mechanism 4 is located above the fourth section of the rail and is responsible for power supply and testing for withstand voltage testing. The turn spacing detection mechanism is equipped with a turn spacing tester, which is located inside the machine platform 1 and connected to the fifth section of the rail and is responsible for power supply and testing for turn spacing testing. At the same time, the machine platform 1 is also equipped with an aging test instrument and a power supply system after aging test, which are connected to the second and third sections of the rail respectively for power supply for motor aging test and operation after test.

[0020] Since the aging test requires the starting capacitor to ensure the normal operation of the motor, while the withstand voltage test requires the starting capacitor to be disconnected, a pressing component 41 is provided above the fourth section of the rail. The pressing component 41 includes a linear drive 411 and a pressing block 412. The pressing block can press down the pressing switch to disconnect the connection between the starting capacitor and the motor, so as to switch between different test functions.

[0021] Preferably, the fixed base 223 includes a base 2231 and a pushing component 2232. The base 2231 includes a support 22311 and a stop 22312. The stop 22312 is located at one end of the support 22311 near the outer side of the machine base 1, and the pushing component 2232 is located at the other end of the support 22311 and faces the support 22311. The pushing component 2232 includes a pushing drive 22321 and a push block 22322. The pushing drive 22321 is a linear electric cylinder, which is also electrically connected to the conductive wheel 213. When the motor is placed on the base 2231, the pushing drive 22321 pushes the motor so that the motor abuts against the stop block 22312, thereby limiting the position of the motor and ensuring the consistency of the motor position. In a specific implementation, the stop block 22312 and the support base 22311 are made of bakelite.

[0022] Furthermore, the number of conductive wheels 221 is the same as the number of sets of power supply rails 23, and they are arranged along the width direction of the machine base 1. Each set of power supply rails 23 is in contact with a set of conductive wheels 221. It can also be understood that by setting different numbers of sets of power supply rails 23 and corresponding numbers of conductive wheels 221, these conductive wheels 221 are respectively connected to the terminal clamps 224 and the drive components 22321, further distinguishing the independent power consumption of different power functions.

[0023] The sprocket circulation mechanism 21 includes a chain 211, a sprocket 212, and a sprocket drive 213. The chain 212 is driven by the sprocket 212, and the sprocket 212 is driven by the sprocket drive 213. The test base 22 is fixed on the chain 211. The sprocket drive 213 adopts a servo drive system.

[0024] In summary, in this example, the test base with its cyclical motion, combined with the segmented power supply rail, not only ensures the continuity of power supply for each testing station, but also guarantees that the power supply for each testing station is set independently and does not affect each other. Therefore, multiple testing stations with different functions can be set up for continuous testing, greatly improving the testing efficiency of the motor.

[0025] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
