A clearance groove 7 is opened on the bottom surface of the placement plate 1. An mounting plate 9 is placed inside the placement groove 19. A plurality of circuit boards 10 are fixedly embedded on the top surface of the mounting plate 9. A test component for testing the circuit boards 10 is provided on the placement plate 1.

[0026] The detection assembly includes a drive board 2, which is placed on top of a placement plate 1. Two first electric push rods 3 are fixedly installed on the top surface of the drive board 2. The output ends of the two first electric push rods 3 pass through the drive board 2 and extend to its bottom. A movable plate 16 is fixedly connected between the output ends of the two first electric push rods 3. Multiple fixed plates 17 are fixedly connected to the bottom surface of the movable plate 16. Four ejector pins 18 are fixedly connected to the bottom surface of each of the multiple fixed plates 17. Light fixtures 20 are fixedly installed on the right side of each of the multiple fixed plates 17. Rotor motors 8 are fixedly installed on the bottom surface of each of the multiple circuit boards 10.

[0027] The mounting plate 9 and the placement groove 19 are attached to each other, the placement groove 19 and the clearance groove 7 are connected, and the top surface of the drive plate 2 has two first through holes. The output ends of the two first electric push rods 3 pass through the two first through holes and are fitted with them with a gap.

[0028] Specifically, the rotor motor 8 is soldered onto the circuit board 10, and then the mounting plate 9 is placed inside the placement slot 19 to restrict the mounting plate 9. Through the action of the clearance slot 7, the rotor motor 8 is housed. The first electric push rod 3 is activated, and the output end of the first electric push rod 3 drives the moving plate 16 to move, causing the ejector pin 18 to move downward and make the ejector pin 18 fit with the circuit board 10. The rotor motor 8 is then tested. If it fails, the lamp 20 emits light to mark the unqualified rotor motor 8.

[0029] It should be noted that the rotor motor 8 and the lamp 20 are both conventional devices known in the prior art, and their specific structures and working principles will not be described in detail here. This application can ensure that the output ends of the two first electric push rods 3 extend and retract simultaneously by using a synchronization controller or other synchronization device, thereby achieving synchronous operation. These synchronization devices are common and mature in the field of electric control, so they will not be described in detail in the specific embodiments. The four pins 18 are respectively distributed with the positive, negative, FG and PWM on the circuit board 10.

[0030] Please see Figures 1 to 3 In this embodiment, the drive board 2 is provided with a cutting assembly for cutting the circuit board 10. The cutting assembly includes a plurality of second electric push rods 4. The plurality of second electric push rods 4 are fixedly installed on the top surface of the drive board 2. The output ends of the plurality of second electric push rods 4 pass through the drive board 2 and extend to its bottom. The output ends of the plurality of second electric push rods 4 are fixedly connected to a linkage plate 14. The bottom surface of the plurality of linkage plates 14 is fixedly connected to a cutting ring 13.

[0031] The top surface of the drive plate 2 has a number of second through holes, and the output ends of the multiple second electric push rods 4 pass through the multiple second through holes and are fitted with them with a clearance.

[0032] Specifically, the cutting ring 13 corresponds to the circuit board 10. When the second electric push rod 4 is activated, the output end of the second electric push rod 4 drives the cutting ring 13 to move downward through the linkage plate 14, thereby cutting the defective rotor motor 8.

[0033] It should be noted that the first electric push rod 3 and the second electric push rod 4 are conventional devices known to the public in the prior art. Their specific structure and working principle will not be described in detail in this article. The multiple second electric push rods 4 are electrically connected to the multiple lamps 20 one by one.

The rotating assembly includes a support plate 5, which is fixedly connected to the top surface of the placement plate 1. The right side of the placement plate 1 is provided with a mounting groove 11, and a drive motor 12 is fixedly installed inside the mounting groove 11. The output shaft of the drive motor 12 is fixedly connected to a drive rod 15, one end of which passes through the mounting groove 11 and extends to the top of the placement plate 1. The drive rod 15 and the drive plate 2 are fixedly connected.

[0035] The top surface of the support plate 5 and the bottom surface of the drive plate 2 are attached to each other. The support plate 5 is located on the left side of the moving plate 16. The drive rod 15 is rotatably connected to the mounting groove 11 and the placement plate 1 through two bearings respectively.

[0036] Specifically, the drive plate 2 is supported by the fit between the support plate 5 and the drive plate 2, thereby improving the stability of the drive plate 2. The drive motor 12 is started, and the output shaft of the drive motor 12 drives the drive rod 15 to rotate, so that the cutting ring 13 and the circuit board 10 correspond.

[0037] The working principle of the above embodiments is as follows:

[0038] The rotor motor 8 is soldered onto the circuit board 10, and then the mounting plate 9 is placed inside the placement slot 19 to restrict the mounting plate 9. The rotor motor 8 is housed by the action of the clearance slot 7. The drive plate 2 is supported by the contact between the support plate 5 and the drive plate 2, improving the stability of the drive plate 2. Then the first electric push rod 3 is activated. The output end of the first electric push rod 3 drives the moving plate 16 to move, causing the ejector pin 18 to move downward and contact the ejector pin 18 with the circuit board 10 to test the rotor motor 8. If it fails, the lamp 20 emits light to mark the unqualified rotor motor 8. Then the drive motor 12 is activated. The output shaft of the drive motor 12 drives the drive rod 15 to rotate, so that the cutting ring 13 corresponds with the circuit board 10. The second electric push rod 4 is activated. The output end of the second electric push rod 4 drives the cutting ring 13 to move downward through the linkage plate 14 to cut the unqualified rotor motor 8.
