Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Example 1

[0027] like Figure 1-6 As shown, a stator feeding device includes a feeding conveying mechanism 1, a flipping mechanism 2, and a mobile pallet 3. The flipping mechanism 2 is arranged on one side of the feeding conveying mechanism 1, and is used to feed the stator and flip the stator to dock with the mobile pallet 3. The mobile pallet 3 is arranged on the feeding conveying mechanism 1, and is used to load the stator, and the mobile pallet 3 moves between the flipping mechanism 2 and the winding and embedding equipment (not shown in the figure) through the feeding conveying mechanism 1; the flipping mechanism 2 includes a flipping seat 21, a vertical rotating shaft 22, and a loading fixture 24. The flipping seat 21 is provided with a vertical rotating shaft 22 rotatably connected thereto, and the vertical rotating shaft 22 is connected to a servo motor. A transfer shaft 23 is provided in the middle of the vertical rotating shaft 22, and a transfer fixture 24 is connected to the end of the transfer shaft 23.

[0028] like Figure 1-2As shown, the flip mechanism 2 also includes a lifting component 25, and the flip seat 21 is connected to the feeding conveying mechanism 1 through the lifting component 25; the lifting component 25 includes a feeding seat 251, a rack 252, a slide rail 253, and a gear 254. The feeding seat 251 is fixed on one side of the feeding conveying mechanism 1, and a rack 252 is fixed on one side thereof. The rack 252 is provided with slide rails 253 fixed on the feeding seat 251 on both sides, and the gear 254 is meshed with the rack 252, and the gear 254 is provided on the inner side of the flip seat 21 and connected to the output end of the servo motor fixed on the outer side of the flip seat 21. The inner side of the flip seat 21 is also provided with a slider slidably connected to the slide rail 253. The servo motor of the lifting component 25 adopts a right-angle reducer to reduce the occupied space. Through the setting of the lifting component 25, the feeding height of the loading fixture 24 can reach the optimal human operating height, reduce the fatigue of the operator, and improve the experience.

[0029] During loading, the loading jig 24 is set vertically, and the stator is hoisted to the top of the loading jig 24 by the workshop crane. The stator is manually assisted in positioning and inserted above the loading jig, and then the lifting component 25 starts to drive the flip seat 21 to rise, so that it reaches the docking height with the mobile pallet 3; then, the flip mechanism 2 flips, flips the stator from a vertical state to a horizontal state, and falls onto the mobile pallet 3, and then the loading and conveying mechanism 1 conveys the mobile pallet 3 and the stator thereon to the winding and embedding equipment to complete the loading of the stator. During the loading and moving process, the stator is firmly positioned, so that the stator transplantation is stable, so that the stator is quickly transported to the winding and embedding equipment through the loading and conveying mechanism 1, which is suitable for the automatic loading of heavy-loaded stators or large stators that are not suitable for grasping. In summary, the utility model has a simple structure, and when loading, it realizes the automatic loading of the stator by combining with the existing plant equipment, and can adapt to the loading of heavy-loaded stators and other stators that are not suitable for grasping, and the loading is fast, stable, and safe, which improves production efficiency.

[0030] Example 2

[0031] Based on the structure of Example 1, Figure 1 As shown, the feeding conveying mechanism 1 includes a base frame 11 and a screw transmission assembly 12 arranged on the base frame 11, a slide rail 3 13 is provided on one side of the screw transmission assembly 12, a conveying seat 14 is provided at the movable end of the screw transmission assembly 13, and the conveying seat 14 is also slidably connected to the slide rail 3 13 through a slider on the slide rail 3 13.

[0032] like Figure 4-5As shown, the mobile tray 3 includes a tray 31 and a translation assembly 1 32. The tray 31 is used to load the stator. The translation assembly 32 is arranged on the conveying seat 14 of the feeding conveying mechanism 1, and can drive the tray 31 to translate in a direction perpendicular to the conveying direction of the feeding conveying mechanism 1. The translation assembly 1 32 includes a rack 2 321, a gear 2 322, and a slide rail 2 323. The rack 2 321 is arranged at the bottom of the tray 31. The gear 2 322 is meshed with the rack 2 321 and connected to the output end of the servo motor fixed on the conveying seat 14. There are two slide rails 2 323 fixed on both sides of the conveying seat 14. The tray 31 is slidably connected with the slide rails 2 323. After the stator is transferred to the mobile tray 3, the mobile tray 3 is transported to the docking position with the winding and embedding device through the feeding conveying mechanism 1, and the translation assembly 1 32 is started to drive the tray 31 close to the winding and embedding device.

[0033] In addition, if Figure 4-6 As shown, the mobile tray 3 also includes a positioning assembly 33 arranged on the tray 31, and the positioning assembly 33 includes a support rod 331, a positioning block 332, a spring top block 333, and a lifting cylinder 334. A positioning block 332 elastically connected to the tray 31 is provided in the middle of the open end of the tray 31, and a plurality of symmetrically arranged support rods 331 are provided on both sides of the positioning block 332. The support rods 331 are used to support the stator. A boss is provided on the top of the positioning block 332 to match the stator slot outside the stator. Springs are fixed on both sides of the bottom of the positioning block 332. A spring top block 333 is inserted into a spring seat 335 and is slidably connected to the spring seat 335 via a spring 336 provided in the spring seat 335. The spring seat 335 is fixed on a cylinder connecting plate 337. The cylinder connecting plate 337 is connected to the output end of the lifting cylinder 334. A detection bracket 338 is also provided below the cylinder connecting plate 337. A detection sensor is provided on the detection bracket 338 and is matched with the lower end of one of the spring top blocks 333. The detection sensor is used to monitor whether the stator is on the tray 31. When the flipping mechanism 2 flips the stator from a vertical state to a horizontal state, the stator falls on a plurality of support rods 331, and the boss on the positioning block 332 is inserted into the stator slot to limit the rotation of the stator. At the same time, the weight of the stator presses down the positioning block 332, the spring 336 is compressed, the spring top block 333 moves down, and its lower end extends out of the spring seat 335 and enters the detection range of the detection sensor. At this time, the detection sensor sends a signal to indicate that the stator has been transferred to the tray. The control system can send a signal to control the translation component 32 to start moving toward the winding setting to separate the stator from the loading fixture 24; conversely, the stator is detached from the tray, the spring top block 333 moves up under the action of the spring 336, and the spring top block 333 leaves the detection range of the detection sensor.

[0034] like Figure 4-5As shown, the tray 31 is also provided with a translation component 2 34 having the same translation direction as the translation component 1 32, and the translation component 2 34 includes a translation cylinder 341, a translation seat 342, and a guide rod 343. There are two translation cylinders 341, which are respectively located on both sides of the positioning component 33. The output ends of the two translation cylinders 341 are provided with translation seats 342, and the translation seats 342 are also slidably connected to the guide rods 343 fixed on the tray 31. The positioning component 33 is arranged on the translation seat 342; in addition, the guide rod 343 is also provided with two push plates 344 slidably connected thereto, and the two push plates 344 are connected into one body by a connecting rod 345 and connected to the translation seat 342. The top of the push plate 344 is provided with a positioning groove 3441 that matches the loading fixture 24, which can ensure that the docking position of the loading fixture 24 and the tray 31 is accurate. After the translation assembly 1 32 translates the tray 31 close to the winding and embedding equipment, the translation assembly 2 34 starts to insert the stator into the positioning device of the winding and embedding equipment, and then the translation assembly 1 32 and the translation assembly 2 34 retreat to complete the loading of the stator.

[0035] like Figure 3 As shown, the loading fixture 24 is used to position the loading stator. Specifically, the loading fixture 24 includes a positioning seat 241, a positioning sleeve 242, a limiting block 1 243, a limiting block 244, and a limiting block 3 245. The positioning seat 241 includes a positioning base plate and arc plates arranged on both sides of the positioning base plate. The inner side of the arc plate is adapted to the outer side of the stator. The positioning sleeve 242 is arranged in the middle of the positioning base plate of the positioning seat 241 and cooperates with the central groove of the stator. The limiting block 1 243 is provided with a plurality of them, which are arranged on the side of the positioning base plate where the arc plate is not arranged, and are used to limit the stator to abut against the outer side of one end of the positioning base plate. The limiting block 244 is arranged on the positioning seat 241. On the side close to the mobile tray 3, which is also located on the opposite side of the limit block 1 243, a limit block 3 245 vertically arranged with the positioning base plate is provided thereon. The limit block 244 cooperates with the positioning groove 3441 to preliminarily locate the circumferential displacement of the stator on the mobile tray 3. The limit block 3 245 is provided with a boss that cooperates with the stator slot on the outer side of the stator on the side close to the positioning sleeve 242. The boss on the limit block 3 245 coincides with the boss on the positioning block 332. Through the cooperation between the limit block 244 and the positioning groove 3441 and the boss on the limit block 3 245 and the stator slot, the stator is accurately positioned when it is transferred from the flipping mechanism 2 to the mobile tray 3, which is convenient for subsequent positioning processing.
