[0002] The current characteristics of micro motors are typically tested manually using handheld measuring instruments on each motor. When testing a large number of micro motors, this method is not only cumbersome and prone to operator fatigue, but also significantly reduces testing efficiency and may result in missed or false detections. For micro motors with excessive current, the conventional repair method is to manually tap the motor to ensure all components are properly aligned, especially the clearances between the motor shaft, stator, and rotor, before retesting the current characteristics. This entire process is time-consuming and labor-intensive.

The forward and backward moving plate 244 is fixed on the telescopic shaft of the third cylinder 241. The third cylinder 241 is mounted on the third fixed plate 22.

The intermediate plate 265 is fixed on the telescopic shaft of the fourth cylinder 261. The fourth cylinder 261 is mounted on the fourth fixed plate 25. The fourth cylinder 261 pushes the intermediate plate 265 to move left and right, thereby driving the left and right moving plate 264 to move linearly to the left or right. To ensure the directional linear motion of the front-to-back moving plate 244 and the left-to-right moving plate 264, the front-to-back moving plate 244 is fixed on the third slider 243, which is slidably mounted on the third linear guide rail 242, which is fixed on the second upright plate 23; the left-to-right moving plate 264 is fixed on the fourth slider 263, which is slidably mounted on the fourth linear guide rail 262, and both the fourth linear guide rail 262 and the fourth fixed plate 25 are fixed on the front-to-back moving plate 244.

[0040] Example 3

[0041] Reference Figure 1-9 As shown, based on the technical solution of the above embodiments, a motor characteristic detection and repair device, regarding the specific structural design of the characteristic detection mechanism 6, is as follows: Figure 4-6It is understood that the power supply detection component 64 is inserted into the rubber sleeve 63. The rubber sleeve 63 can play the role of limiting and flexible installation. The rubber sleeve 63 is clamped in the clamping plate 62. The clamping plate 62 is driven by the seventh cylinder 60 to move up and down, thereby causing the power supply detection component 64 to move up and down accordingly.

Specifically, the power supply detection component 64 includes a first power supply head 641, a leakage current detection head 642, and a second power supply head 643. The first power supply head 641 and the second power supply head 643 are used to contact the two terminals of the finished motor 4, and the leakage current detection head 642 is used to contact the housing of the finished motor 4. The seventh cylinder 60 is fixed on the seventh fixing plate 61.

The finished motor 4 is located between the limiting passage 650 and the limiting plate 68 and cooperates with the power supply detection component 64.

[0042] Example 4

[0043] Reference Figure 1-9 As shown, based on the technical solution of the above embodiments, a motor characteristic detection and repair device, regarding the specific structural design of the knocking current mechanism 7, is as follows: Figure 7-9It is understood that the movable side component 73 is connected to the lifting cylinder 70 through the connecting column 71, so that the movable side component 73 can adjust its own height. The movable side component 73 includes a cylinder installed in the horizontal direction and a clamping plate. The clamping plate is located between two adjacent detection plates 65 in the horizontal direction, and can transfer the finished motor 4 to the clamping plate that is flush with the detection plate 65 through the conveying and moving mechanism 2. Specifically, the movable side assembly 73 includes an eighth fixing plate 730 connected to the connecting column 71. The eighth fixing plate 730 is slidably mounted on the fifth upright plate 72. An eighth cylinder 731 and a ninth cylinder 732 are arranged side by side on the eighth upright plate. The clamping plate consists of two identical first clamping plates 735 and second clamping plates 736. The eighth cylinder 731 is connected to the first clamping plate 735, and the ninth cylinder 732 is connected to the second clamping plate 736. The fixed side assembly 75 includes a first bakelite board 751 and a second bakelite board 752. The first bakelite board 751 is mounted on the first limiting member 753, and the second bakelite board 752 is mounted on the second limiting member 754. The first limiting member 753 and the second limiting member 754 are matched with the dimensions of the clamping plate and fixed on the sixth upright plate 74. When the first clamping plate 735 is at the same height as the first bakelite board 751, the second clamping plate 736 is at the same height as the detection plate 65. In addition, the eighth fixing plate 730 is fixed on the eighth slider 733, the eighth slider 733 is vertically slidably mounted on the eighth linear guide 734, the eighth linear guide 734 is vertically fixed on the fifth upright plate 72, the first limiting member 753 and the second limiting member 754 have the same structure, the first bakelite board 751 and the second bakelite board 752 have the same structure and material, and are used to block the unqualified motor product 4 from being hit by the mounting plate.

[0044] Working principle: For the conveying and moving mechanism 2, the forward and backward moving component 24 first moves forward to its position, causing the conveying fixture 28 to hold the finished motor 4. Then, the left and right moving component 26 moves to the left to move the finished motor 4 to the characteristic testing station to work with the characteristic testing mechanism 6 (the testing equipment has multiple testing stations with different functions). After being moved to its position, the finished motor 4 is located on the limiting passage 650 of the testing plate 65. After the characteristic testing operation is completed, the forward and backward moving component 24 and the left and right moving component 26 are reset, and the entire action process is completed. The next operation process is repeated. Regarding the operation of the characteristic testing mechanism 6, the seventh cylinder 60 starts, driving the power supply testing component 64 to rise. After rising to the position, the first power supply head 641 or the second power supply head 643 contacts the terminals of the finished motor 4 to supply power (the first power supply head 641 or the second power supply head 643 is electrically connected to the power supply on the characteristic testing instrument). The characteristic testing instrument determines whether the finished motor 4 is qualified based on the feedback data of the power supply to the finished motor 4. At the same time, the leakage detection head 642 also contacts the bottom iron shell of the finished motor 4. If there is leakage in the internal winding wire group of the finished motor 4, the leakage detection head 642 will feed back the leakage failure signal to the controller of the whole machine for processing. The controller controls the conveying and moving mechanism 2 to move the finished motor 4 that fails the characteristic test to the mounting plate for subsequent hammering operations. For the current-tapping mechanism 7, the movable side component 73 and the fixed side component 75 are designed with two sets, one upper and one lower. When the second mounting plate 736 is parallel to the detection plate 65, the conveying and moving mechanism 2 transports the finished motor 4 with poor current detected by the characteristic detection station to this current-tapping station. When the start command is received, the current-tapping operation starts. First, the lifting cylinder 70 descends. After descending to the position, the first mounting plate 735 is parallel to the detection plate 65 (so that the overall working efficiency will not be affected when the tapping action is performed at this station). Then, the ninth cylinder 732 is activated, pushing the finished motor 4 to be tapped and colliding it with the first bakelite board 751 to perform the current-tapping operation. After the action is completed, the ninth cylinder 732 returns to the original position, and the current-tapping process ends.
