[0050] In the above structure, if Figure 1-2 As shown in Figures 9 and 10, the unloading conveying mechanism 4 is a ground rail conveying structure, including a bottom frame 41, a rack 3 42 and a slide rail 43 arranged along the length direction of the bottom frame 41, and a gear driving assembly 44 matched with the rack 3 42 and a slide rail 4 43 are arranged at the bottom of the mobile turning platform 7. Through the cooperation of the gear driving assembly 44 and the rack 3, multiple mobile turning platforms 7 can be driven to move in different directions at the same time, with good flexibility.

[0051] like Figure 3-4 As shown, the flipping mechanism 2 includes a flipping seat 21, a vertical rotating shaft 22, and a loading jig 24. The flipping seat 21 is provided with a vertical rotating shaft 22 rotatably connected thereto, 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 jig 24 is connected to the end of the transfer shaft 23.

[0052] In the above structure, if Figure 3-4 As 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.

[0053] For a heavy-loaded stator, during loading, the loading jig 24 is vertically arranged, and the stator is hoisted to the top of the loading jig by a crane, and the stator is manually assisted in positioning and inserted to the top of the loading jig, and then the lifting assembly is started 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, completing 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 can be 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. During unloading, according to the processing inspection result of the stator, the corresponding mobile turning table 7 moves to the winding and embedding equipment to pick up the material.

After picking up the material, the mobile turning table 7 moves to the unloading tray 5 through the unloading conveying mechanism 4. The mobile turning table 7 turns over, and the stator is turned over and placed on the unloading tray 5. Then the unloading tray 1 transports it to the finished product Conveyor line, during the material unloading and moving process, the stator is firmly positioned, so that the stator transplantation is stable; if the processing is unqualified, the mobile turning table 7 connected to the unloading tray 2 6 is moved to the winding and embedding equipment through the unloading conveying mechanism 4 to pick up the material, and the winding and embedding equipment picks up the stator to the mobile turning table 7. After picking up the material, the mobile turning table 7 is moved to the unloading tray 2 6 through the unloading conveying mechanism 4, and the mobile turning table 7 is turned over, and the stator is turned over and placed on the unloading tray 2 6, and then the unloading tray 2 6 transfers it to the NG trolley to realize the unloading of the stator. In summary, the utility model has a simple structure, and the material is loaded by combining with the existing factory equipment during loading. When unloading, the stator can be unloaded separately according to the processing status of the stator, reducing subsequent processes; it realizes automatic loading and unloading of the stator, and the loading and unloading is fast, stable and safe, which improves production efficiency.

[0054] Example 2

[0055] Based on the structure of embodiment 1, wherein, Figure 6-7As shown, the mobile tray 3 includes a tray 1 31 and a translation assembly 1 32. The tray 1 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 1 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 1 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, which are fixed on both sides of the conveying seat 14. The tray 1 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 conveyed to the docking position with the winding and embedding device by the feeding conveying mechanism 1, and the translation assembly 1 32 is started to drive the tray 1 31 close to the winding and embedding device.

[0056] like Figure 6-8 As shown, the tray 131 is a U-shaped frame structure with an open upper end, including a bottom plate and side plates arranged on both sides of the bottom plate. A positioning component 133 is provided on the tray 131, and the positioning component 133 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 131 is provided in the middle of the open end of the tray 131, 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. The top of the positioning block 332 is provided with a boss that matches the stator slot outside the stator. Spring top blocks 333 are fixed on both sides of the bottom of the positioning block 332. The spring top block 333 is inserted in the spring seat 335 and is slidably connected to the spring seat 335 through a spring 336 arranged in the spring seat 335. The spring seat 335 is fixed on a cylinder connecting plate 337, and 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 to cooperate 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 1. The control system can send a signal to control the translation component 1 32 to start moving toward the winding setting to separate the stator from the loading fixture 1 24; conversely, if the stator is detached from the tray 1, the spring top block 333 moves up under the action of the spring 1 336, and the spring top block 333 leaves the detection range of the detection sensor.

[0057] like Figure 5 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 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 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 is located on the side of the movable tray 3 and is also located on the opposite side of the limit block 1 243. A limit block 3 245 is provided thereon, which is vertically arranged with the positioning base plate. The limit block 244 cooperates with the positioning groove 3441 to preliminarily locate the circumferential displacement of the stator on the movable 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 can be accurately positioned when it is transferred from the flipping mechanism 2 to the movable tray 3, which is convenient for subsequent positioning processing.

[0060] Based on the structure of Example 2, Fig. 9As shown, the movable flip table 7 includes a movable bottom plate 71, a flip side plate 72, and a second vertical rotating shaft 73. The movable bottom plate 71 is provided with two symmetrically arranged flip side plates 72. A second vertical rotating shaft 73 rotatably connected thereto is provided between the two flip side plates 72. An adapter sleeve 74 is provided in the middle of the second vertical rotating shaft 73, and a second loading fixture 75 is provided at the end of the adapter sleeve 74. The second loading fixture 75 is used to position the stator when unloading, and includes a positioning cylinder 751 and a positioning bar 752. The positioning cylinder 751 is a cylindrical sleeve structure, and one end thereof close to the adapter sleeve 74 is provided with a step abutting against the end face of the stator, and the other end is inserted into the stator and matched with the inner side wall of the stator. The positioning bar 752 is provided with a plurality of axially arranged positioning cylinders 751, and is inlaid on the outer side of the positioning cylinder 751, and a boss for limiting the circumferential displacement of the stator is provided on the positioning bar 752.

[0061] like Figure 10-12As shown, the unloading tray 1 5 has the same structure as the unloading tray 2 6, including a tray 2 51 and a positioning assembly 2 52 arranged on the tray 2 51, the positioning assembly 2 52 includes a supporting roller 521, a limiting base 522, a positioning slider 523, a spring 2 524, a fixing seat 525, and an operating rod 526. The tray 2 51 is a U-shaped frame structure with an open upper end, and a positioning slider 523 elastically connected to the tray 2 51 is provided in the middle of the open end. A plurality of symmetrically arranged supporting rollers 521 are provided on both sides of the positioning slider 523, and the supporting rollers 521 are used to support the stator. A boss is provided on the top of the positioning slider 523 that cooperates with the stator slot outside the stator, and the lower end of the positioning slider 523 is inserted into the limiting base 522 and is slidably connected to the limiting base 522. The second spring 524 is arranged inside the limiting base 522, one end of which is connected to the bottom of the positioning slider 523, and the other end is connected to the limiting base 522. The limiting base 522 and the fixing base 525 are both fixed on the bottom plate of the second tray 51. One end of the operating rod 526 is hinged to the fixing base 525, and the other end extends into the limiting base 522 and is inserted into the driving hole at the lower end of the positioning slider 523. The size of the driving hole is larger than the outer diameter of the operating rod 526. One end of the operating rod 525 extending into the limiting base 522 extends to the outside of the limiting base 522 and is connected to the hook plate 527 fixed on the second tray 51. Two stopper positions cooperating with the operating rod 526 are arranged on the hook plate 524 in the vertical direction, and the two stopper positions are respectively an upper stopper position and a lower stopper position. In addition, the inner sides of the two side plates of the second tray 51 are also provided with a limiting plate 528, and the two limiting plates 528 can cooperate to limit the axial displacement of the stator. When the mobile turning table 7 is docked with the unloading tray 1 5 or the unloading tray 2 6, the operating rod 525 is in the upper stop position, the stator flips from the vertical state to the horizontal state, the stator falls on multiple support rollers 521, and the two ends of the stator are stuck between the two limit plates 528. At the same time, the boss on the positioning slider 523 is inserted into the stator slot to limit the rotation of the stator. The weight of the stator presses down the positioning slider 523, the spring 2 524 is compressed, and the positioning slider 523 moves downward. Since the driving hole at the lower end of the positioning slider 523 is larger than the outer diameter of the operating rod 526, the operating rod 526 moves less at this time and is located between the lower stop position and the upper stop position, thereby realizing the circumferential positioning of the stator; conversely, when the stator is detached from the tray 2 51, the positioning slider 523 moves upward under the action of the spring 2 524, and the upper stop position stops the upward movement of the positioning slider 523. If the stator is an NG product or in other situations, the stator on tray 2 51 needs to be rotated for observation and inspection, then the operating rod 526 is moved to one side and hit into the lower stop position, the operating rod 526 is blocked by the lower stop position, the positioning slider 523 is driven downward by the operating rod 526 and cannot move upward, the boss on the positioning slider 523 is disengaged from the stator, and the stator can be operated to rotate on the support roller 521.

The lifting and positioning component 2 107 cooperates with the positioning hole 511 on the tray 2 51 to position the tray 2 51 on the pushing seat 104, so as to avoid the movement of the unloading tray 2 6 when the pushing component is pushed. The structure of the lifting and positioning component 2 107 of the utility model is similar to the structure and function of the lifting and positioning component 1 91, and will not be described in detail here. When unqualified products are unloaded, the mobile turning table 7 takes the material and moves to the transfer platform 10, and the stator is turned over and placed on the unloading tray 6. The lifting and positioning component 107 is started to fix the tray 51 and the pushing seat 104. The pushing component pushes the unloading tray 6 and pushes it to the entrance end of the NG trolley 8. The lifting and positioning component 107 retracts to make the unloading tray 6 and the pushing seat 104 active. Then the unloading tray 6 is manually pushed, and with the assistance of the roller plate 105, it is pushed to the NG trolley 8 to realize the unloading of unqualified products.

A groove is provided in the middle of the movable pressing plate 85. When the NG trolley 8 approaches the transfer platform 10, the inclined plate 86 is inserted into the groove. As the NG trolley 8 gradually approaches the transfer platform 10, the inclined surface drives the movable pressing plate 85 to move downward, thereby driving the movable baffle 82 to move downward, so as to facilitate the pushing of the tray 2 51 on the transfer platform 10 into the placement groove 81. During the pushing process, the roller plate 105 and the ball in the placement groove 81 assist in pushing, reducing the pushing force and making the pushing more convenient.
