All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0025] First embodiment

[0026] As shown in the attached Figure 1 to the attached Figure 5 : The automatic feeding mechanism for the motor rotor includes a body 1, including: a conveying component 2, arranged inside the body 1; an adjusting component 3, arranged inside the body 1, including a support plate 301 installed on the inner wall of the body 1, the upper surface of the support plate 301 is fixedly connected with a servo motor 302, and an adjusting structure is arranged above the support plate 301; a tensioning component 4, arranged inside the body 1.

[0027] As Figure 1 and Figure 2As shown in the figure, through grooves 101 are provided on both the front and back of the body 1. Two sets of support feet 102 are fixedly connected to the bottom surface of the body 1. By providing the through grooves 101 and the support feet 102, the device can be conveniently connected to the internal mechanism while supporting the body 1 to keep it stable and prevent the body 1 from shaking during use.

[0028] As Figure 1 , Figure 2 and Figure 3 shown, the adjustment structure of the adjustment component 3 includes a controller 303 installed on the upper surface of the support plate 301. The bottom surface of the support plate 301 is rotatably connected to a threaded rod 304 through a bearing. The top end of the threaded rod 304 is fixedly connected to the output end of the servo motor 302. A threaded tube 305 is threadedly connected to the outer surface of the threaded rod 304. The bottom end of the threaded tube 305 is fixedly installed with a pressure sensor 306. The pressure sensor 306 is located between the two through grooves 101. By cooperating with the servo motor 302, the threaded rod 304 and the threaded tube 305, a thrust can be applied to the pressure sensor 306, enabling the pressure sensor 306 to push the tensioning component 4 and sensing the pressure when the tensioning component 4 and the conveyor belt 203 are tensioned. Thus, in cooperation with the controller 303, the servo motor 302 is started after the sensed pressure drops, enabling the pressure sensor 306 to press the tensioning component 4 again to ensure that the conveyor belt 203 remains in a tensioned state.

[0029] As Figure 1 and Figure 2 shown, two brackets 103 are fixedly connected to the upper surface of the body 1. The bottom surface of each bracket 103 is rotatably connected to a set of connecting shafts 104 through a set of bearings. A rubber sleeve 105 is fixedly connected to the outer surface of each connecting shaft 104. Through the cooperation of the brackets 103, the connecting shafts 104 and the rubber sleeves 105, the motor rotor can be guided to keep it neat.

[0030] As Figure 3 shown, two connecting seats 309 are fixedly connected to the upper surface of the support plate 301. The opposite side surfaces of the two connecting seats 309 are fixedly connected to the inner wall of the body 1. The support plate 301 can be reinforced through the connecting seats 309 to prevent the support plate 301 from falling off.

[0031] Second Embodiment

[0032] As Figure 1 , Figure 2 and Figure 3As shown, the conveying assembly 2 includes a driving motor 201 installed on the back of the body 1, and the inner wall of the body 1 is rotatably connected to a group of transmission rods 202 through two groups of bearings, wherein the rear end of one transmission rod 202 is fixedly connected to the output end of the driving motor 201, and a group of transmission rods 202 are connected through a conveyor belt 203. The driving motor 201 can provide power to the transmission rods 202 to ensure that the transmission rods 202 can drive the conveyor belt 203 to rotate and transport the motor rotor.

[0033] Third embodiment

[0034] like Figure 2 and Figure 4 As shown, the tensioning assembly 4 includes two connecting blocks 401 slidably arranged on the inner walls of the two through grooves 101, and the side surfaces of the two connecting blocks 401 close to each other are commonly fixedly connected with a push plate 402, and the upper surface of the push plate 402 is fixedly installed with the bottom surface of the pressure sensor 306, and the side surfaces of the two connecting blocks 401 close to each other are commonly rotatably connected with a roller 403 through two bearings. Through the cooperation of the push plate 402 and the pressure sensor 306, the pressure sensor 306 can apply a thrust to the push plate 402, thereby ensuring that the roller 403 can tension the conveyor belt 203.

[0035] like Figure 3 As shown, two sliding holes 307 are provided on the upper surface of the support plate 301, and the inner wall of each sliding hole 307 is slidably connected to a limiting rod 308. The bottom surfaces of the two limiting rods 308 are fixedly connected to the upper surface of the push plate 402. Through the cooperation of the sliding hole 307 and the limiting rod 308, the tensioning assembly 4 can be limited, making the tensioning assembly 4 more stable during the up and down movement.

[0036] Working principle: When in use, start the drive motor 201, so that the drive motor 201 drives the transmission rod 202 to rotate, and the transmission rod 202 drives the conveyor belt 203 to rotate to transport the motor rotor. After the conveyor belt 203 becomes loose after long-term use, the pressure on the pressure sensor 306 is reduced, and then the pressure sensor 306 sends a signal to the controller 303. The controller 303 starts the servo motor 302 to work, and the servo motor 302 drives the threaded rod 304 to rotate. The threaded rod 304 cooperates with the threaded tube 305 to push the pressure sensor 306 to move downward, so that the pressure sensor 306 can push the tensioning component 4 to tension the conveyor belt 203, and when the pressure sensed by the pressure sensor 306 reaches the set value, it can cooperate with the controller 303 to stop the servo motor 302.
