[0053] Specifically,

[0054] First, the brush holder is loaded onto the processing surface from the outside. At this time, the brush holder is clamped and moved to the other end by the clamping and conveying module 201 and placed on the carrier of the brush holder linear module 202. The brush holder moves on the carrier of the linear module to the bottom of the loading and unloading module 203. The loading and unloading module 203 grabs the brush holder in the carrier and moves it to the first station 304 of the turntable 301. The brush holder is placed on the material carrier 303 of the first station 304, ready for subsequent processing.

[0055] In this embodiment, the oil-impregnated bearing feeding assembly 4 includes an oil-impregnated bearing vibratory feeder 401 and a misaligned feeder 402;

[0056] The oil-impregnated bearing vibratory feeder 401 and the misaligned feeder 402 are both located on the processing surface and on one side of the brush holder oil-impregnated bearing press-fitting machine 312. The oil-impregnated bearing vibratory feeder 401 discharges the oil-impregnated bearing and the misaligned feeder 402 divides and pushes it to the lower position of the brush holder oil-impregnated bearing press-fitting machine 312. The brush holder is located at the upper position of the brush holder oil-impregnated bearing press-fitting machine 312. The brush holder and the oil-impregnated bearing are press-fitted by the brush holder oil-impregnated bearing press-fitting machine 312.

[0057] Specifically,

[0058] After the brush holder is loaded onto the material carrier 303 at the first station 304 of the turntable 301, the turntable 301 will rotate with the self-rotating motor 302, processing sequentially. The material carrier 303 at the first station 304 rotates with the turntable 301 to the second station 305, which is empty. At this time, the turntable waits for the rotation rhythm to rotate the second station 305 to the third station 306. The processing equipment at the third station 306 is the brush holder oil-impregnated bearing press-fitting machine 312. 12 will grab the brush holder to the upper position. During the process of the turntable 301 rotating to the third position and being placed on the upper position of the brush holder oil bearing press machine 312, the oil bearing will be fed synchronously by the oil bearing vibrating plate feeder 401 and transferred individually to the lower position of the brush holder oil bearing press machine 312 by the staggered feeder 402. When the brush holder and the oil bearing are both on the brush holder oil bearing press machine 312, they will be pressed by the brush holder oil bearing press machine 312 to press the brush holder and the oil bearing into the first semi-finished product.

[0059] After being pressed into the first semi-finished product at the third station 306, the turntable 301 rotates to the fourth station 307. The fourth station 307 is a pressing depth testing machine 313, which checks whether the first semi-finished product meets the pressing standard. If it does not meet the standard, it is rejected and sent to the defective belt. If it meets the standard, it enters the next station, the fifth station 308.

[0060] In this embodiment, the Hall plate loading assembly 5 includes a Hall plate linear module 501, a Hall plate CCD detection component 502, and a Hall plate handling assembly 503;

[0061] The Hall plate linear module 501, the Hall plate CCD detection component 502, and the Hall plate transport assembly 503 are all located on the processing surface. The Hall plate transport assembly 503 picks up the Hall plate on the Hall plate linear module 501 and aligns it with the Hall plate CCD detection component 502 for detection. The Hall plate is then transported by the Hall plate transport assembly 503 to the Hall plate brush holder pre-assembly machine 314 for pre-assembly with the brush holder and oil-impregnated bearing assembly at the third station 306.

[0062] Specifically,

[0063] During the process of the first semi-finished product entering the fifth station 308, the Hall plate is loaded in the Hall plate linear module 501 and picked up and transported by the Hall plate handling component 503 to the Hall plate CCD detection component 502 to check whether the weld points of the loaded Hall plate are qualified. The qualified Hall plate is then transported by the Hall plate handling component 503 to the Hall plate brush holder pre-assembly machine 314 on the fifth station 308 for pre-assembly.

[0064] After the pre-assembly at the fifth station is completed, the Hall plate brush holder is pressed into the sixth station 309 by the rotation of the turntable 301 and then pressed into the second semi-finished product of the brush holder, oil-impregnated bearing and Hall plate.

[0065] In this embodiment, the pin feeding assembly 6 includes a pin vibratory feeder 601, a pin rotating machine 603, and a pin conveying assembly 602;

[0066] The pin vibratory feeder 601, the pin rotating machine 603, and the pin transport assembly 602 are all located on the processing surface. The pin transport assembly 602 picks up the pins from the pin vibratory feeder 601, places them on the pin rotating machine 603 to make the pins stand upright, and then transports the upright pins to the pin pre-assembly machine 316 and the sixth station 309 to pre-assemble the oil-impregnated bearing, brush holder, and Hall plate components.

[0067] Specifically,

[0068] First, the second semi-finished product at station 309, rotating with turntable 301, enters the pin pre-assembly machine 316 at station 310. During this process, the pin vibrating feeder 601 feeds the external pins, which are then transported by the pin transport assembly 602 to the pin rotating machine 603. The horizontally lying pins are rotated into an upright position, and then the upright pins are transported again by the pin transport assembly 602 to the pin pre-assembly machine 316. At this point, the upright pins need to be transported twice to be pre-assembled into the second semi-finished product. When the seventh station… After the two upright pins are pre-assembled with the second semi-finished product, the third semi-finished product is formed. As the turntable 301 rotates, it enters the pin and brush holder secondary pressing machine 317 in the eighth station 311, where the two pre-assembled pins are fully pressed with the second semi-finished product. Finally, the finished product is formed in the eighth station 311. Then, the finished product in the eighth station 311 returns to the starting point, the first station 304, as the turntable 301 rotates. After the finished product is in the first station 304, it will be picked up and transported by the loading and unloading module 203 to the unloading component 7. The unloading component 7 then transports it to the next machine for processing.
