[0115] The testing mechanism 4 uses a floating type connecting shaft to match the electric terminal and the fixed assembly 42 to fix, power and stall the motor, which provides favorable conditions for the current test of the motor, improves the test efficiency and detection quality of the motor and improves the product qualification rate.

[0116] Optionally, the material collecting station 36 comprises a first material collecting sub-station and a second material collecting sub-station. The second material collecting sub-station is arranged in coincidence with or adjacent to the material feeding station 34.

The material conveying driving member is capable of driving the material collecting bin to move to the material collecting station 36 or away from the material collecting station 36.

[0126] In other embodiments, only one material collecting station 36 can be used, and a qualified product collecting bin is arranged corresponding to the first material collecting bin 51 and the second material collecting bin 52, which is used for collecting the tested motor with qualified product.

[0127] Optionally, the motor locked-rotor testing device further comprises a control mechanism 6 installed on the rack 1. Optionally, the motor locked-rotor testing device comprises a power supply, and the power supply is electrically connected with the control mechanism 6, or the control mechanism 6 is electrically connected with an external socket. The material conveying mechanism, the material taking mechanism 3 and the material collecting mechanism 5 are electrically connected with the control mechanism 6. Specifically, each material sensor and each driving member are electrically connected with the control mechanism 6 to receive the control of the control mechanism 6.

[0128] Optionally, the motor locked-rotor testing device further comprises a display mechanism 7 installed on the rack 1 and electrically connected with the control mechanism 6, which is used for displaying the testing data.

[0129] In the embodiment, the material feeding mechanism 2 is located below one end of the longitudinal frame body 313, and the material collecting mechanism 5 is located below the other end of the longitudinal frame body 313. The testing mechanism 4 is located between the two longitudinal frame bodies 313 and between the material conveying track 56 and the material conveying track 21, and is located directly below the moving range of the transverse frame body 314.

[0130] Please refer to Figures 1-5 , the working principle of the motor locked-rotor testing device is that the material taking mechanism 3 is used for transferring the motor from the material feeding mechanism 2 to the testing mechanism 4. The testing mechanism 4 is used for fixing the main body and the output shaft of the motor and applying power to the motor, so as to realize the locked-rotor of the motor.

[0131] Specifically, the feeding plate 22 is located at the feeding station 34, and the motor is carried on the feeding plate 22. Under the action of the control mechanism 6, the longitudinal driving member 311 and the transverse moving assembly work to drive the clamping jaw 33 to move to the position directly above the feeding station 34, and the driving assembly 32 works to grab the motor on the feeding station 34. The longitudinal driving member 311 and the transverse moving assembly work to move the motor to the position directly above the testing station 35, and the driving assembly 32 works to place the motor on the support 41.

[0132] At this time, when the motor is the first motor 100, the main body of the first motor 100 is placed between the pressing rod 422 and the fixing rod 423, then the fixing driving member works, the pressing rod 422 is pressed down to fix the main body of the first motor 100, the power connection driving member 432 works, the first power connection terminal 431 is electrically connected with the power connection part of the first motor 100, and the first motor 100 works. If the top end of the first connecting shaft 433 is not completely aligned with the connecting hole of the first motor 100 when the first motor 100 is fixed, that is, the shape of the top end of the first connecting shaft 433 does not completely coincide with the shape of the connecting hole, the first connecting shaft 433 moves downward under the extrusion of the first motor 100, the elastic member 441 deforms, the first connecting rod 112 abuts against the position of the connecting hole of the first motor 100, and after the first motor 100 is powered, the connecting hole rotates, and the first connecting rod 112 can extend into the connecting hole. The first connecting shaft 433 rotates, the first limiting protrusion 4332 abuts against the limiting member 434, so that the first motor 100 is blocked, and the test result is obtained. The power connection driving member 432 drives the power connection terminal to contact the power connection part of the motor. After the first motor 100 is blocked, the torque received is large, and the test mechanism 4 needs to power the first motor 100 again to make the motor reverse to the initial position, so as to achieve the effect of protecting the motor. The pressing cylinder works, and the pressing rod 422 moves away from the fixing rod 423 to release the motor.

[0133] When the motor is the second motor 200, the motor is placed between the two fixed blocks 425, the fixed cylinder works, the two fixed blocks 425 clamp the motor, the second power terminal 440 is in contact with the power terminal of the second motor 200, and the second motor 200 rotates. If the top end of the second connecting shaft 438 is not completely aligned with the connecting hole of the second motor 200 when the second motor 200 is fixed, that is, the shape of the top end of the second connecting shaft 438 does not completely coincide with the shape of the connecting hole, the second connecting shaft 438 moves downward under the extrusion of the second motor 200, the elastic member 441 deforms, the second connecting rod 112 abuts against the connecting hole of the second motor 200, and after the second motor 200 is powered, the connecting hole rotates, and the second connecting rod 112 can extend into the connecting hole. The second connecting shaft 438 is fixed, so that the second motor 200 is blocked. If the second connecting shaft 438 can extend into the connecting hole when the second motor 200 is fixed, the second motor 200 can be directly blocked, and a test result is obtained. The fixed cylinder works, and the two fixed blocks 425 loosen the motor. The push cylinder works, and the connecting shaft moves downward to disengage from the connecting hole of the motor.

[0134] The taking mechanism 3 works, and the motor whose test is completed is transferred to the receiving bin or the conveying plate 22 of the feeding mechanism 2 according to the test result of the test mechanism 4. The first material sensor 23 and the fourth material sensor 55 can detect the motor, and when the number of the motor reaches a preset number, corresponding control of the material driving member and the conveying driving member is performed to convey the motor out.

[0135] Please refer to Figure 6 The motor blocking test method is also provided, and the method can be based on the motor blocking test device. For the convenience of understanding, please refer to Figures 1-5 The motor blocking test method is also provided, and the method can be based on the motor blocking test device. For the convenience of understanding, please refer to

[0136] The motor blocking test method comprises the following steps:

[0137] S10, the taking mechanism 3 transfers the motor from the feeding mechanism 2 to the test mechanism 4, the test mechanism 4 fixes the main body and the output shaft of the motor, and the motor is powered to test the motor, and a test result is obtained.

[0140] obtaining a time when the motor starts to be powered as a first time, determining whether the motor is powered off by itself, and obtaining a time when the motor is powered off by itself as a second time when the motor is powered off by itself;

[0141] calculating a difference between the first time and the second time as a first difference, determining whether the first difference is greater than a first threshold, obtaining a time when the motor is powered again as a third time when the first difference is greater than the first threshold, calculating a difference between the third time and the second time as a second difference, and determining whether the second difference is less than a second threshold, and obtaining a qualified test result when the second difference is less than the second threshold;

[0142] obtaining an unqualified test result when the second difference is greater than or equal to the second threshold;

[0143] obtaining an unqualified test result when the difference is less than or equal to the threshold.

[0144] It can be understood that the motor has a protection device, and when the motor is stalled, the protection device automatically disconnects the current of the motor to protect the motor. The first threshold is a pre-set value, for example, 2 seconds, 3 seconds, etc. It is worth mentioning that when the motor is the first motor 100, the first threshold can be 8 seconds to 10 seconds, preferably 9 seconds; when the motor is the second motor 200, the first threshold can be 6 seconds to 8 seconds, preferably 7 seconds. The second threshold can be 2 seconds to 3 seconds.

[0145] S20, the test mechanism 4 releases the main body and the output shaft of the motor, and powers off the motor, and according to the test result, the material taking mechanism 3 transfers the motor from the test mechanism 4 to the material collecting mechanism 5 or the material feeding mechanism 2.

[0146] In this embodiment, obtaining the test result indicates that the test is completed, at which time the test mechanism 4 can release the main body and the output shaft of the motor, and power off the motor.

[0147] Further, according to the test result, the material taking mechanism 3 transfers the motor from the test mechanism 4 to the material collecting mechanism 5 or the material feeding mechanism 2, which includes:

[0148] When the test result is qualified, the material taking mechanism 3 transfers the motor corresponding to the qualified test result to the material feeding mechanism 2;

[0149] When the test result is unqualified, the material taking mechanism 3 transfers the motor corresponding to the unqualified test result to the material collecting mechanism 5.

[0150] It can be understood that the material collecting mechanism 5 is used to collect unqualified motors, and the material feeding mechanism 2 is used to collect qualified motors.

[0151] Optionally, after the test result is obtained, the method further comprises: the testing mechanism 4 re-energizes the motor to make the motor reverse to the initial position.

[0152] It can be understood that when the motor is the first motor 100, the torque received by the motor after the motor is blocked is larger, and the testing mechanism 4 needs to re-energize the motor to make the motor reverse to the initial position, so as to achieve the effect of protecting the motor. Specifically, the power connection driving part 432 drives the power connection terminal to contact the power connection part of the motor.
