[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. 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.

[0035] Example 1

[0036] like Figure 1-10 As shown, a stator unloading device includes an unloading conveying mechanism 1, an unloading tray 1 2, and an unloading tray 2 3. The unloading conveying mechanism 1 is provided with at least one mobile turning table 4, and the mobile turning table 4 is used to pick up materials and convey the processed stator to the unloading tray 1 2 or the unloading tray 2 3 through the unloading conveying mechanism 1. The unloading tray 1 2 is connected to a finished product conveyor line (not shown in the figure), and the unloading tray 2 3 is connected to an NG trolley 5; the mobile turning table 4 includes a moving bottom plate 41, a turning side plate 42, and a vertical rotating shaft 43. Two symmetrically arranged turning side plates 42 are provided on the moving bottom plate 41, and a vertical rotating shaft 43 rotatably connected thereto is provided between the two turning side plates 42, and an adapter sleeve 44 is provided in the middle of the vertical rotating shaft 43, and a loading fixture 45 is provided at the end of the adapter sleeve 44.

[0037] In this embodiment, Figure 1-2 As shown, there are two mobile turning tables 4, and the turning directions of the two mobile turning tables 4 are different. One is connected to the unloading tray 1 2 through the unloading conveying mechanism 1, and the other is connected to the unloading tray 2 3 through the unloading conveying mechanism 1. It should be noted that the turning directions of the two mobile turning tables 4 can also be the same. In this case, one mobile turning table 4 can be set, and the number and turning direction of the mobile turning tables 4 can be adjusted according to the layout direction and working rhythm of the finished product conveyor line machine and the NG trolley.

[0038] In the above structure, if Figure 3 As shown, the loading fixture 45 includes a positioning cylinder 451 and a positioning bar 422. The positioning cylinder 451 is a cylindrical sleeve structure, and one end thereof close to the adapter sleeve 44 is provided with a step abutting against the end face of the stator, and the other end is inserted in the stator and cooperates with the inner wall of the stator. The positioning bar 422 is provided with multiple axially arranged along the positioning cylinder 451, inlaid on the outer side of the positioning cylinder 451, and the positioning bar 422 is provided with a boss for limiting the circumferential displacement of the stator.

[0039] Among them, Figure 1-2 As shown, the unloading conveying mechanism 1 is a ground rail conveying structure, including a bottom frame 11, a rack 12 and a slide rail 13 arranged along the length direction of the bottom frame 11, and a gear driving assembly 14 matched with the rack 12 and a slide block slidably connected with the slide rail 13 are provided at the bottom of the mobile turning platform 4. Through the cooperation of the gear driving assembly 14 and the rack 12, multiple mobile turning platforms 4 can be driven to move in different directions at the same time, with good flexibility.

[0040] During unloading, according to the processing inspection result of the stator, the corresponding mobile turning table 4 moves to the winding and embedding equipment to pick up the material. If the processing is qualified, the mobile turning table 3 connected to the unloading tray 2 moves to the winding and embedding equipment to pick up the material through the unloading conveying mechanism 1. The winding and embedding equipment picks up the stator and puts it on the mobile turning table 4. At this time, the stator is in a vertical state. After picking up the material, the mobile turning table 4 moves to the unloading tray 2 through the unloading conveying mechanism 1. The mobile turning table 4 turns over and turns the stator over and places it on the unloading tray 2. Then the unloading tray 2 transports it to the finished product conveyor line. During the unloading movement process, the stator is firmly positioned. The stator transplantation is stable, so that it can be quickly moved through the unloading conveying mechanism 1, and can adapt to the automatic unloading of heavy-loaded stators or large stators that are not suitable for grasping; if the processing is unqualified, the mobile turning table 4 connected to the unloading tray 2 3 is moved to the winding and embedding equipment through the unloading conveying mechanism 1, and the winding and embedding equipment takes the stator to the mobile turning table 4. After taking the material, the mobile turning table 4 is moved to the unloading tray 2 3 through the unloading conveying mechanism 1, and the mobile turning table 4 is turned over, and the stator is turned over and placed on the unloading tray 2 3, and then the unloading tray 2 3 transfers it to the NG trolley 5 to realize the unloading of the stator. In summary, the utility model has a simple structure, and can separate the stators according to their processing status during unloading, reducing subsequent processes; it realizes the automatic unloading of the stator, which is suitable for the unloading of heavy-loaded stators that are not suitable for grasping, and the unloading is fast, stable, and safe, which improves production efficiency.

[0041] Example 2

[0042] Based on the structure of Example 1, Figure 4 , 5As shown, the unloading tray 1 2 has the same structure as the unloading tray 2 3, including a tray 21 and a positioning assembly 22 arranged on the tray 21, the positioning assembly 22 including a supporting roller 221, a limiting base 222, and a positioning slider 223, the tray 21 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 slider 223 elastically connected to the tray 21 is provided in the middle of the open end, a plurality of symmetrically arranged supporting rollers 221 are provided on both sides of the positioning slider 223, the supporting rollers 221 are used to support the stator, a boss is provided on the top of the positioning slider 223 which cooperates with the stator slot outside the stator, and the lower end of the positioning slider 223 is inserted in the limiting base 222 and is slidably connected to the limiting base 222, and a limiting plate 228 is also provided on the inner side of the two side plates of the tray 21, and the two limiting plates 228 cooperate to limit the axial displacement of the stator.

[0043] In the above structure, if Figure 4 , 5 As shown, the positioning assembly 22 also includes a spring 224, a fixing seat 225, and an operating rod 226. The spring 224 is arranged inside the limiting base 222, one end of which is connected to the bottom of the positioning slider 223, and the other end is connected to the limiting base 222. The limiting base 222 and the fixing seat 225 are both fixed on the bottom plate of the tray 21. One end of the operating rod 226 is hinged to the fixing seat 225, and the other end extends into the limiting base 222 and is inserted into the driving hole at the lower end of the positioning slider 223. The size of the driving hole is larger than the outer diameter of the operating rod 226. One end of the operating rod 226 extends into the limiting base 222 and extends to the outside of the limiting base 222 and is connected to a hook plate 227 fixed on the tray 21. The hook plate 227 is provided with two stop positions that cooperate with the operating rod 226 in the vertical direction, and the two stop positions are respectively an upper stop position and a lower stop position.

[0044] When the mobile turning table 4 is docked with the unloading tray 1 2 or the unloading tray 2 3, the operating rod 225 is in the upper stop position, the stator flips from the vertical state to the horizontal state, the stator falls on multiple support rollers 221, and the two ends of the stator are stuck between the two limit plates 228. At the same time, the boss on the positioning slider 223 is inserted into the stator slot to limit the rotation of the stator. The weight of the stator presses down the positioning slider 223, the spring 224 is compressed, and the positioning slider 223 moves down. Since the driving hole at the lower end of the positioning slider 223 is larger than the outer diameter of the operating rod 226, the operating rod 226 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 223 moves upward under the action of the spring 224, and the upper stop position stops the upward movement of the positioning slider 223. 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 226 is moved to one side and hit into the lower stop position, the operating rod 226 is blocked by the lower stop position, the positioning slider 223 is driven downward by the operating rod 226 and cannot move upward, the boss on the positioning slider 223 is disengaged from the stator, and the stator can be operated to rotate on the support roller 221.

[0045] like Figure 6 , 7 As shown, the unloading tray 2 is arranged on the rotating platform 6 and is connected to the finished product conveyor line through the rotating platform 6. The rotating platform 6 includes a base frame 3 61, a turntable 62, and a conveying roller assembly 63. The turntable 62 is arranged on the top of the base frame 3 61 and is rotatably connected to the base frame 3 61. The conveying roller assembly 63 is arranged on the turntable 62, and is used to convey the unloading tray 2 to the finished product conveyor line. The turntable 62 is also provided with at least one lifting and positioning assembly 64. The tray 21 is provided with a positioning hole 211 that cooperates with the lifting and positioning assembly 64. Through the cooperation of the lifting and positioning assembly 64 and the positioning hole 211, the position of the tray 21 on the turntable can be positioned to ensure that the unloading tray 2 and the mobile turning table 4 are accurately docked. Specifically, the lifting and positioning assembly 64 includes a positioning seat 641, a positioning cylinder 642, a guide sleeve 643, and a positioning pin 644. The positioning seat 641 is fixed on the turntable 92, the positioning cylinder 642 is fixed on the positioning seat 641, and a positioning pin 644 is provided at its output end. The guide sleeve 643 is fixed on the top of the positioning seat 641, and is sleeved on the outside of the positioning pin 644 and is slidably connected to the positioning pin 644 to guide the movement of the positioning pin 644.

[0046] When it is necessary to position the unloading tray 5, the positioning cylinder 642 is started to drive the positioning pin 644 to rise and insert into the positioning hole 211, so as to realize the positioning of the unloading tray 2 and the turntable 62; conversely, the positioning cylinder 642 is started to drive the positioning pin 644 to move down and disengage from the positioning hole, and the unloading tray 2 is in an active state and can be transported to the corresponding position by the conveying roller assembly 63. When unloading qualified products, initially, the lifting and positioning assembly 64 fixes the unloading tray 2 and the turntable 62, and the mobile turning table 4 moves to the rotating platform 6 after taking the material, and the stator is turned over and placed on the unloading tray 2, and then the lifting and positioning assembly 64 is retracted, so that the unloading tray 2 and the turntable 62 are in an active state, and then the conveying roller assembly 63 is started to transport the unloading tray 2 to the finished product conveying line for subsequent processing, so as to realize the unloading of qualified products.

A pressure plate 76 is provided on the outer side of the roller plate 75. The pressure plate 76 is an inverted L-shaped plate, and its upper end horizontal plate is pressed on the top surface of the bottom plate of the tray 21, and at least one lifting and positioning assembly 77 is provided on the upper end horizontal plate of the pressure plate 76. The lifting and positioning assembly 77 cooperates with the positioning hole 211 on the tray 21 to position the tray 21 on the pushing seat 74, so as to avoid the movement of the unloading tray 23 when the pushing assembly is pushed. The structure of the lifting and positioning assembly 77 of the utility model is similar to the structure and function of the lifting and positioning assembly 61, and will not be described in detail here.

[0048] When unqualified products are unloaded, the mobile turning table 4 takes the material and moves to the transfer platform 7, the stator is turned over and placed on the unloading tray 23, the lifting and positioning component 77 is started to fix the tray 21 and the pushing seat 74, the pushing component pushes the unloading tray 23, and pushes it to the entrance end of the NG trolley 5, the lifting and positioning component 77 retracts, so that the unloading tray 23 and the pushing seat 74 are in an active state, and then the unloading tray 23 is manually pushed, and with the assistance of the roller plate 75, it is pushed to the NG trolley 5 to realize the unloading of unqualified products.

[0049] like Figure 8-10As shown, the NG trolley 5 is movably connected to the transfer platform 7, a placement groove 51 is provided on the top, and a plurality of balls arranged in an array are provided on the bottom surface of the placement groove 51, and the balls are universal balls; the placement groove 51 is an open groove opening toward the transfer platform 7, and a movable baffle 52 is provided at the open end thereof, and the movable baffle 52 is movably connected to the NG trolley 5 through a driving assembly, and the driving assembly includes a guide block 53, a guide connecting rod 54, a movable pressure plate 55, and an inclined plate 56. The guide block 53 is fixed at the end of the NG trolley 5 close to the transfer platform 7, and the movable pressure plate 55 is provided below the guide block 53, and its top There are two guide links 54 fixedly connected on both sides of the part, the upper ends of the guide links 54 are inserted into the guide blocks 53 and are slidably connected to the guide blocks 53, and the tops thereof extend out of the guide blocks 53 and are connected to the movable baffle 52 located above the guide blocks 53. The guide blocks 53 and the movable pressure plates 55 are also connected at both ends by tension springs 57. The inclined plate 56 is arranged at one end of the transfer platform 7 close to the NG trolley 5, and a slope is provided at its lower end.

[0050] When the NG trolley 5 approaches the transfer platform 7, a groove is provided in the middle of the movable pressing plate 55, and the inclined plate 56 is inserted into the groove. As the NG trolley 5 gradually approaches the transfer platform 7, the inclined surface drives the movable pressing plate 55 to move downward, thereby driving the movable baffle 52 to move downward, so as to facilitate the tray 21 on the transfer platform 7 to be pushed into the placement groove 51. During the pushing process, the roller plate 75 and the ball in the placement groove 51 assist in pushing, reducing the pushing force and making the pushing more convenient.

In addition, the cooperation between the movable pressing plate 55 and the inclined plate 56 can not only ensure the docking of the NG trolley, but also drive the movable baffle 52 at the same time, so as to facilitate the unloading of the unloading tray 23.
