The coreless motor has outstanding energy-saving characteristics, sensitive and convenient control characteristics, and stable operating characteristics. Its technological advancement is very obvious. During the production process of the coreless motor, torque needs to be detected, so a torque detection device is required. During the detection process of the detection device, due to the small volume of the coreless motor, when personnel pick up the motor, affected by the volume, it is difficult to achieve batch measurement of the product. At the same time, when multiple coreless motors are connected to the torque detection device, it is difficult to improve the connection speed between the coreless motor and the torque detection device.

[0024] A detection method for a torque detection device of a hollow cup motor includes the following steps; First, when the device is performing detection, place the hollow cup motor to be detected on the other half of the feeding plate 41; when the device detection is completed, then start the clamping assembly 6 to reduce the clamping limit on the hollow cup motor, and then start the third motor 57. The third motor 57 rotates the plate 514 through the moving block 513 on the bidirectional screw 512 to retract the push plate 515 with the extension column 516 to the third motor 57. At the same time, the bidirectional screw 512 drives the winding disc 510 to rotate and wind the winding belt 56, so that the winding belt 56 squeezes the elastic plate 59 through the mounting plate 55 to take out the triangular limit plate 54 from the limit frame 52. At the same time, start the electric telescopic rod 45 to push the hollow cup motor with the alarm 3 on the detector 2 corresponding to the detection slot to emit light and alarm into the waste recycling port 419. Then open the protective cover 51, and then start the first motor 410 and the second motor 418, so that the first motor 410 drives the connecting rod 44 in the swing plate 46 to swing in the second waist-shaped through hole 48, so that the connecting rod 44 drives the feeding plate 41 to slide in the chute through the slider 43. At the same time, the cam 415 squeezes the moving plate 414, so that the moving plate 414 drives the push rod 416 to push the qualified hollow cup motor on the feeding plate 41 efficiently, and at the same time, the feeding plate 41 transports the other half of the hollow cup motor to be detected into the detection table 1 for detection.

[0025] Working principle of the present invention: When using the device, first place the hollow cup motor to be detected on the feeding plate 41, and then rotate the protective cover 51 so that the protective cover 51 drives the limiting frame 52 to be inserted into the installation through hole 53, causing the limiting frame 52 to slide on the triangular limiting plate 54, and at the same time causing the triangular limiting plate 54 to slide and be inserted into the limiting frame 52. Then start the third motor 57, so that the output end of the third motor 57 drives the bidirectional lead screw 512 to rotate through the winding disc 510, and at the same time causes the bidirectional lead screw 512 to drive the two moving blocks 513 to move relatively. At the same time, the moving block 513 drives the push plate 515 through the rotating plate 514, so that the push plate 515 drives the extension column 516 to push the hollow cup motor to move in the detection groove towards the detector 2. Then start the fourth motor 66, so that the output end of the fourth motor 66 drives the multi-threaded bidirectional screw 62 to rotate, and at the same time causes the multi-threaded bidirectional screw 62 to drive the two electric telescopic plates 63 to move relatively. Then start the electric telescopic plates 63, so that the electric telescopic plates 63 drive the swing plate 46 and the rubber pad 65 to squeeze against the hollow cup motor. Then start the detector 2 to perform torque detection on the hollow cup motor;After the detection, when a hollow cup motor with unqualified torque is detected, the corresponding alarm 3 on the detector 2 will emit light for alarm. Then, the third motor 57 is operated in reverse, causing the third motor 57 to drive the bidirectional lead screw 512 to rotate, causing the bidirectional lead screw 512 to drive the moving block 513 to move to the support plate 511. The moving block 513 contracts and pushes the push plate 515 and the extension column 516 through the rotating plate 514. At the same time, the bidirectional lead screw 512 drives the winding disc 510 to wind the winding belt 56, causing the winding belt 56 to drive the mounting plate 55 to slide on the guide rod 58 and squeeze the elastic plate 59, so that the elastic plate 59 is in a compressed state. At the same time, the mounting plate 55 drives the triangular limit plate 54 to be taken out of the limit frame 52. Then, the above operation of the clamping assembly 6 is reversed. Then, the electric telescopic rod 45 is started, causing the electric telescopic rod 45 to push the hollow cup motor with the alarm 3 emitting light into the waste recycling port 419. Then, the protective cover 51 is opened. Then, the first motor 410 is started, causing the output end of the first motor 410 to drive the swing plate 46 to swing intermittently in the detection table 1. At the same time, the swing plate 46 drives the connecting rod 44 to slide in the second kidney-shaped through hole 48. At the same time, the connecting rod 44 slides in the first kidney-shaped through hole 47. At the same time, the connecting rod 44 drives the slider 43 to slide in the rectangular through hole 42. At the same time, the feeding plate 41 slides intermittently in the chute. At the same time, the second motor 418 is started, causing the second motor 418 to drive the cam 415 to rotate, causing the cam 415 to slide and squeeze the moving plate 414, causing the moving plate 414 to squeeze the slide rod 412, the push rod 416 and the spring 413, so that the spring 413 is in a compressed state, causing the slide rod 412 and the push rod 416 to slide on the fixed plate 411. At the same time, the push rod 416 reciprocally pushes on the feeding plate 41 to push the hollow cup motor on the feeding plate 41 to be discharged. Then, the above operation is repeated to transport the other half of the feeding plate 41 filled with hollow cup motors to the lower part of the protective cover 51 for the above detection operation.;
