[0045] In the snap ring feeding, sorting, and pitch-changing steering mechanism 3, the vibrating material tray 31 feeds the horizontally placed snap rings into the snap ring receiving and sorting assembly 32. At this time, the bolt cylinder 32-1.16 located next to the bearing seat 32-1.4 is in the extended state, which is to press the pressure rod a32-1.6 and pressure rod b32-1.7 together. The bolt cylinder 31-1.1 on the vibrating material tray 31, which controls the snap ring discharge, is also in the extended state, driving the clamping shaft 31-1.3 to rise, which is to discharge the snap ring and facilitate the delivery of the snap ring. Inside the snap ring receiving and sorting assembly 32, when the proximity sensor 32-1.12 inside the snap ring receiving and sorting assembly 32 senses the snap ring, the bolt cylinder 32-1.16 located next to the bearing seat 32-1.4 retracts. The pressure rods a32-1.6 and b32-1.7, under their own weight and the elastic force of the spring 32-1.9, tilt up to press the snap ring, thus controlling the snap ring discharge on the vibrating material tray 31. When the cylinder retracts, it lowers the clamping shaft 31-1.3, blocking the retaining spring inside the vibrating material tray 31 and preventing material discharge. The slide cylinder 32-1.13 extends, moving away from the discharge port of the vibrating material tray 31, along with the proximity sensor 32-1.12 (which detects the presence of the retaining spring), the bearing housing 32-1.4, the adjacent bolt cylinder 32-1.16, the receiving rotating shaft 32-1.5, gear 32-1.2, rack 32-1.3, and the square cylinder 32-1.1 (which controls 90° rotation), all moving away from the vibrating material tray 31. After the slide cylinder 32-1.13 extends to the outlet, 32-1.1 controls the 90° directional square cylinder to retract, moving the rack 32-1.3 along with it. At this time, the receiving rotating shaft 32-1.5 rotates 90°, and the pressure rods a32-1.6 and b32-1.7, the pin 32-1.8, and the spring 32-1.9 rotate 90° accordingly, changing the snap ring from a horizontal to a vertical state, so that the snap ring gripper 42-1.2 can clamp the snap ring. The above operation steps can realize the automatic feeding and sorting of snap rings.

[0046] When the retaining ring changes from a horizontal to a vertical position, the vertical transfer cylinder cylinder 41-1.5, along with two expanding retaining ring parallel gripper cylinders 42-1.11, two parallel retaining ring gripper cylinders 42-1.3, and two pressing cylinders 42-1.9, descends. The two parallel retaining ring gripper cylinders 42-1.3 near the feeding side clamp the retaining ring. Then, the vertical transfer cylinder cylinder 41-1.5, along with the two expanding retaining ring parallel gripper cylinders 42-1.11, two parallel retaining ring gripper cylinders 42-1.3, and two pressing cylinders 42-1.9, rises. After reaching the upper position, the rodless cylinder 41-1.3, along with the two parallel retaining ring gripper cylinders 42-1.3 holding the retaining ring, moves to above the retaining ring pitch-changing steering assembly 33 tooling. The vertical transfer cylinder cylinder 41-1.5, along with the two parallel retaining ring gripper cylinders holding the retaining ring... Cylinder 42-1.3 descends, placing the circlip onto the circlip pitch-shifting assembly 33. Then, the vertically moving cylindrical cylinder 41-1.5, along with two expanding circlip parallel gripper cylinders 42-1.11, two parallel circlip gripper cylinders 42-1.3, and two pressing cylinders 42-1.9, rises. Image sensor 43-1.4 takes a picture to determine if the circlip is misplaced. If misplaced, the steering square cylinder 33-1.3 below the circlip pitch-shifting assembly 33 moves linearly with rack 2 33-1.5. Rack 2 33-1.5 rotates gear 2 33-1.4, which in turn rotates the circlip steering shaft 33-1.6. This, in turn, rotates the cover plate 33-1.11, spring 2 33-1.12, and clamping block 33-1.13 that hold the circlip, rotating the circlip to the correct position. Then, the two parallel snap ring gripper cylinders 42-1.3 near the snap ring outlet are moved to the receiving and sorting position by the rodless cylinder 41-1.3. The vertical transfer cylinder cylinder 41-1.5, along with the two expanding snap ring parallel gripper cylinders 42-1.11, the two parallel snap ring gripper cylinders 42-1.3, and the two pressing cylinders 42-1.9, descend. The two parallel snap ring gripper cylinders 42-1.3 near the outlet close and clamp the two springs. At the same time, the two expanding snap ring parallel grippers above the pitch steering assembly 33 tooling... Claw cylinder 42-1.11 closes to clamp the snap ring that was just adjusted in position. Then, the vertical transfer cylinder cylinder 41-1.5, along with two expanding snap ring parallel gripper cylinders 42-1.11, two parallel snap ring gripper cylinders 42-1.3, and two pressing cylinders 42-1.9, rises. Then, rodless cylinder 41-1.3 moves the two parallel snap ring gripper cylinders 42-1.3 and the two pressing cylinders 42-1.9, which are close to the discharge port of the vibrating plate, to above the snap ring pitch-changing steering assembly 33 tooling and the iron core rotation mechanism 5.

[0047] Before the snap ring can be placed on the iron core rotation mechanism 5, the servo motor 51 drives the iron core placement fixture 57 to rotate via the reducer 52, thereby rotating the iron core and ensuring it is in the correct position so that the snap ring can be placed on it. Since the snap ring and the iron core are tightly fitted, when placing the snap ring on the iron core placement fixture 57, the two expanding snap ring grippers 42-1.12 need to be pre-controlled to be arranged in a boss shape to open the snap ring during clamping. During placement, the two expanding snap ring grippers 42-1.12 slowly loosen, and the spacing between the snap rings gradually decreases, preventing any change in the snap ring's position. Thus, the snap ring can be placed on the iron core. (Simultaneously, the two parallel snap ring gripper cylinders 42-1.3 near the discharge point also...) Release the grippers and place the snap ring above the snap ring pitch-changing steering assembly 33. Then, the two pressing cylinders 42-1.9 extend, driving the snap ring pressing rod 42-1.10 to press the snap ring down, so that the snap ring is installed into the iron core. Then, the pressing cylinder 42-1.9 retracts, and the vertical transfer cylinder 41-1.5, along with the two expanding snap ring parallel gripper cylinders 42-1.11, two parallel snap ring gripper cylinders 42-1.3, and two pressing cylinders 42-1.9, rises. The rodless lever 41-1.3 transfers the two snap ring pressing cylinders 42-1.9 and the two parallel snap ring gripper cylinders 42-1.3 near the vibrating plate outlet to directly above the snap ring pitch-changing steering assembly 33 and the receiving and sorting assembly 32, respectively. The above steps are repeated.

[0048] After repeating three times, inserting a snap ring into the iron core is complete. When the rodless air lever 41-1.3 moves the two snap ring pressing cylinders 42-1.9 and the two parallel snap ring gripper cylinders 42-1.3 near the vibratory feeder outlet to directly above the snap ring pitch-changing steering assembly 33 and the receiving and sorting assembly 32, the iron core transport mechanism 6 moves the iron core transport gripper 66 to above the iron core placement fixture 57. Then, the iron core transport cylindrical cylinder 63 extends and lowers the iron core transport gripper 66 to the appropriate position. At this time, the iron core is clamped by the iron core transport parallel gripper cylinder 65, and the cylindrical cylinder 63 retracts, causing the iron core to rise. The iron core with the snap ring installed is moved to the other end by the iron core transport rodless cylinder 62. Then, the iron core is placed on the magnet insertion fixture 15, ready for the magnet insertion process. Thus, the automatic snap ring assembly is completed.

[0049] This automatic snap ring assembly equipment features a novel structural design. It can replace workers in inserting snap rings into the motor rotor core, improving the efficiency of snap ring insertion into the motor rotor core, while also increasing the assembly accuracy of snap ring insertion, reducing the assembly cost of the motor rotor, and improving the product qualification rate.

Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model.
