[0030] Please see Figure 1 - Figure 6 A rotor insertion and tilting groove positioning mechanism includes a support frame 1, a switching mechanism 2, and a detection mechanism 3. The support frame 1 has a rotor conveying groove 11 and a detection section 12. A conveying section 13 is located upstream of the detection section 12. The conveying section 13 and the detection section 12 are connected by a switching section 14. The conveying section 13, the switching section 14, and the detection section 12 all have conveying grooves 11, and the conveying grooves 11 are interconnected.
[0031] The switching mechanism 2 includes multiple switching plates 21 for separating the rotor, and a detection plate 22 is provided downstream of the switching plates 21. Both the detection plate 22 and the switching plates 21 are semi-arc-shaped. The leftmost switching plate 21 is aligned with the rotor at the end of the conveying section 13. The switching mechanism 2 also includes a separating cylinder 23. The output end of the separating cylinder 23 is connected to a plate 24. A rodless cylinder 25 is fixed on the plate 24. A switching plate 26 is connected to the rodless cylinder 25. The detection plate 22 and the multiple switching plates 21 are all fixed to the switching plate 26. The lower side of the switching plate 26 is slidably connected to the plate 24. The conveying direction of the rodless cylinder 25 is opposite to that of the separating rotor. The conveying direction is vertical. A limit plate 27 is fixed on the switching plate 21. Two limit plates 27 are provided on each switching plate 21. The distance between the two limit plates 27 is greater than the diameter of the lower end of the positioning rod 322. The limit plates 27 are located on the upper side of the rotor core and do not contact the rotor. The limit plates 27 prevent the rotor from tipping over during movement. When the rotor of the conveying section 13 moves to its moving end, the separation cylinder 23 extends, causing the switching plate 21 to move via the plate 24. The switching plate 21 moves the rotor at the end of the conveying section 13 along the switching section 14, eventually moving it to the connection end between the switching section 14 and the detection section 12, completing the separation of a single rotor. A base plate supports the support frame 1.
[0032] The detection mechanism 3 includes a positioning component 32 for positioning the rotor and a tooth 31 for inserting into the inclined slot. The tooth 31 is connected to the detection card plate 22 and is inserted into the inclined slot for detection.
[0033] The positioning component 32 includes a support plate 321, which is fixed on the support frame 1. A longitudinally movable positioning rod 322 is provided on the support plate 321. The lower end of the positioning rod 322 is circular, and an elastic insertion rod 323 is connected to the lower end of the positioning rod 322. A gear 324 is rotatably connected to the support plate 321. The positioning rod 322 is slidably connected to the gear 324. A gear 325 meshes with the gear 324. A positioning motor 326 is connected to the gear 325. The positioning motor 326 is fixed to the support plate 321, and the gear 325 is fixed to the output shaft of the positioning motor 326.
[0034] The positioning rod 322 has a synchronization surface 3221, and the gear 324 has a synchronization groove adapted to the positioning rod 322. The support plate 321 is fixed with a positioning cylinder 327. The output end of the positioning cylinder 327 is connected to a connecting plate 3271. The connecting plate 3271 is rotatably connected to the positioning rod 322. The gear 324 does not move longitudinally. The positioning rod 322 moves up and down through the positioning cylinder 327. When there is a rotor under the positioning rod 322, the positioning cylinder 327 causes the positioning rod 322 to descend, and the gear 324 rotates to insert the insertion rod 323 into the rotor groove.
[0035] The lower end of the insertion rod 323 is tapered, which facilitates insertion into the rotor slot. A mounting slot is provided on the positioning rod 322, and the upper end of the insertion rod 323 is located within this slot. A sealing plate is fixed to the lower end of the positioning rod 322 to prevent the insertion rod 323 from falling out. A spring 328 is installed within the mounting slot, with both ends of the spring 328 connected to the mounting slot and the insertion rod 323, respectively. A positioning block 4 is connected to the positioning motor 326, and the positioning block 4 is connected to the shaft of the positioning motor 326. A proximity switch 5 is fixed on the support plate 321. The use of the proximity switch 5 is existing technology and will not be described in detail. When the positioning block 4 moves directly below the proximity switch 5, the positioning motor 326 stops rotating. The proximity switch 5 ensures that the positioning motor 326 can still accurately rotate one revolution after prolonged operation. A sensor (not shown in the diagram) is located on the rear side of the detection plate 22 to sense whether the insertion tooth 31 is inserted into the inclined slot. This sensor is existing technology and will not be described in detail.
[0036] Downstream of the detection section 12, a separation component 6 is provided. The separation component 6 includes a pulling cylinder 61, which is fixed to the base plate. The output end of the pulling cylinder 61 is connected to a separation block 62, which is slidably connected to the base plate. A channel is provided on the separation block 62, which is the same width as the conveying trough 11. A pusher plate 63 is provided on one side of the pulling cylinder 61, which is slidably connected to the base plate. A guide groove 631 is provided on the pusher plate 63, which has a straight section and an inclined section. A guide rod 64 is fixed on the separation block 62 and inserted into the guide groove 631. An inclined plate 65 is provided on the other side of the pulling cylinder 61, and a collection trough is provided at the lower end (not shown in the diagram). Downstream of the separation block 62, a receiving component 7 is provided, which also has a conveying trough 11. The receiving component 7 is used to convey qualified rotors.
[0037] In use, the separating cylinder 23 extends, and the plate 24 moves along with the rodless cylinder 25 and the switching plate 26. The switching plate 26 moves along with the switching clamp 21 and the detection clamp 22. The leftmost switching clamp 21 causes the rotor at the end of the conveying section 13 to move along the switching section 14, eventually reaching the connection end between the switching section 14 and the detection section 12, completing the separation of a single rotor on the conveying section 13. Then, the rodless cylinder 25 causes the switching plate 26 to move to the right, allowing the rotor to move within the detection section 12. The extended rod of the separating cylinder 23 retracts, causing the plate 24 to return. The plate 24, along with the... As the switching plate 26 moves, it carries the switching plate 21 and the detection plate 22. Finally, the rodless cylinder 25 moves the switching plate 26 to the left, eventually returning it to its original position. Then, it pushes the rotor at the end of the conveying section 13 again, causing the rotor to switch between each switching plate 21 until all switching plates 21 contain rotors. At this point, the rotor is moved again within the detection section 12, moving it directly below the positioning rod 322. The switching plate 21 still holds the rotor. Then, the positioning cylinder 327, through the connecting plate 3271, moves the positioning rod 32... 2. The positioning rod 322 descends, carrying the insertion rod 323. Finally, the insertion rod 323 inserts into the rotor slot and contacts it. Then, the positioning motor 326 causes gear two 325 to rotate, which in turn causes gear one 324 to rotate. Gear one 324 then causes the positioning rod 322 to rotate, which in turn causes the insertion rod 323 to rotate. The insertion rod 323 then causes the rotor to rotate. At this time, the switching plate 21 keeps the rotor stable during rotation. When the positioning block 4 rotates one revolution, it stops. Then, the separation cylinder 23 returns, causing the plate 24 to return, carrying the switching plate. 26 moves, the switching plate 26 moves with the switching card plate 21 and the detection card plate 22, and finally, the rodless cylinder 25 causes the switching plate 26 to move to the left and eventually return to its original position. After returning, the inclined groove corresponds to the insertion tooth 31. The separation cylinder 23 passes through the plate body 24, the switching plate 26 causes the switching card plate 21 to move, and the detection card plate 22 moves towards the rotor together, so that the insertion tooth 31 is inserted into the inclined groove. After the detection is completed, the rodless cylinder 25 causes the switching plate 26 to move to the right, and the detection card plate 22 causes the rotor after detection to move to the right, and finally enters the receiving part 7 through the separation block 62. If the inserter 31 cannot be inserted, the sensor cannot detect it, and the sensor light illuminates. At this time, the rodless cylinder 25 still moves to the right, and the defective rotor moves to the separation block 62. The detection plate 22 leaves, and then the pull cylinder 61 pulls the separation block 62 to move. At the same time, the guide rod 64 moves in the straight section. When the rotor moves to the range of the inclined plate 65, the guide rod 64 enters the inclined section. The guide rod 64 causes the pusher plate 63 to move towards the defective rotor, pushing the defective rotor away from the separation block 62. Finally, the rotor falls onto the inclined plate 65 and then slides down into the collection tank.

The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments.
