[0002] Motor iron core: As the core component inside the motor, the iron core is a non-professional term in the electrical industry, and the iron core is also the magnetic core. The iron core (magnetic core) plays a crucial role in the entire motor. It is used to increase the magnetic flux of the inductor coil to achieve the maximum conversion of electromagnetic power. The motor iron core is usually composed of a stator and a rotor. The existing technologies have the following problems when rubber coating the motor iron core:

[0003] Currently, before rubber coating the motor iron core, multiple end plates need to be placed one by one in multiple cavities of the iron core blank. However, most of the existing technologies rely on manual labor to load multiple end plates into multiple cavities. Since the number of end plates to be loaded is relatively large, the loading of the end plates is relatively inconvenient. At the same time, a large amount of manual loading operation time is wasted, and the efficiency of rubber coating the motor iron core is affected.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1. By horizontally laying multiple end plates in the material box and making the conveyor belt convey the iron core blank, by driving the two limiting plates to move towards each other, the two limiting plates limit the iron core blank through two first protective pads, thus conveniently realizing the limitation of the iron core blank, and further effectively improving the convenience of subsequent loading of end plates;

[0019] 2. By driving the lead screw to rotate, the lead screw causes the second guiding block to horizontally slide along the inner wall of the second guiding groove. The second guiding block makes the pushing plate move horizontally. The pushing plate pushes multiple end plates in the material box through the second protective pad, making the multiple end plates horizontally move along the inner wall of the material box. The frontmost end plate enters the guiding box through the blanking groove and falls into a cavity of the iron core blank through the guiding box, thus conveniently realizing the loading of one end plate, and further effectively improving the convenience of loading end plates;

[0020] 3. By driving the circular toothed plate to rotate, the circular toothed plate causes the rotating disk to rotate, and the rotating disk causes the iron core blank between the two limiting plates to rotate synchronously. When another cavity of the iron core blank is vertically aligned with the guiding box, the sector gear disengages from the third gear and meshes with the second gear again, and the rotating disk stops rotating. The pushing plate operates again, and multiple end plates are successively pushed by the pushing plate into multiple cavities of the iron core blank, thus conveniently realizing the intermittent rotation of the iron core blank and the continuous loading of end plates, and further effectively improving the convenience of loading end plates.

[0050] A process of a motor iron core encapsulation tooling includes the following steps:

[0051] S1. Limiting of the iron core blank:

[0052] By horizontally laying a plurality of end plates in the material box 13 and making the conveyor belt 12 convey the iron core blank, by driving the two limiting plates 22 to move towards each other, the two limiting plates 22 limit the iron core blank through the two first protective pads 23;

[0053] S2. Loading a single end plate:

[0054] By driving the lead screw 75 to rotate, the lead screw 75 causes the second guide block 74 to slide horizontally along the inner wall of the second guide groove 73. The second guide block 74 causes the pusher plate 71 to move horizontally. The pusher plate 71 pushes multiple end plates in the cartridge 13 through the second protective pad 72, causing the multiple end plates to move horizontally along the inner wall of the cartridge 13. The foremost end plate enters the guiding box 16 through the blanking groove 15 and falls into a cavity of the iron core blank through the guiding box 16;

[0055] S3. Continuously load the end plates:

[0056] By driving the circular tooth plate 46 to rotate, the circular tooth plate 46 causes the rotating disk 41 to rotate. The rotating disk 41 causes the iron core blank between the two limiting plates 22 to rotate synchronously. When another cavity of the iron core blank is vertically aligned with the guiding box 16, the sector gear 541 disengages from the third gear 59 and meshes with the second gear 56 again. The rotating disk 41 stops rotating, and the pusher plate 71 operates again. Multiple end plates are successively pushed by the pusher plate 71 into multiple cavities of the iron core blank.

[0057] Working principle: When the device is in use, first, multiple end plates are horizontally laid in the cartridge 13, and the last end plate contacts one side of the second protective pad 72. The foremost end plate is aligned with the eaves of the blanking groove 15. Then, start the conveyor belt 12 to convey, and place multiple iron core blanks to be rubber-coated on the upper surface of the conveyor belt 12 one by one. At this time, the conveyor belt 12 starts to convey the iron core blanks until an iron core blank is vertically aligned with the axis of the rotating disk 41, and then stop the operation of the conveyor belt 12;

[0058] Subsequently, by turning on the first motor 29, the drive shaft of the first motor 29 causes the first rotating rod 31 to rotate. The first rotating rod 31 causes a double-headed screw 28 to rotate through two first synchronous pulleys 32 and a first synchronous belt 33. The first rotating rod 31 causes another double-headed screw 28 to rotate through two second synchronous pulleys 34 and a second synchronous belt 35. At this time, the two double-headed screws 28 rotate synchronously and in the same direction. The two double-headed screws 28 cause the adjacent two first guide blocks 25 to slide towards each other along the inner walls of the corresponding first guide grooves 24. The four first guide blocks 25 cause the two limiting plates 22 to move towards each other through four first connecting rods 26. When the first protective pads 23 in the two limiting plates 22 are in close contact with the outer wall of the iron core blank, the two limiting plates 22 limit the iron core blank through the two first protective pads 23, thus conveniently realizing the limitation of the iron core blank and effectively improving the convenience of subsequent loading of the end plates;

[0059] Subsequently, by starting the second motor 51, the drive shaft of the second motor 51 rotates the second rotating rod 54, the second rotating rod 54 rotates the sector gear 541, the sector gear 541 drives the second gear 56 to rotate, the second gear 56 rotates the second transmission rod 55, the second transmission rod 55 rotates the two first bevel gears 57, the two first bevel gears 57 drive the two second bevel gears 76 to rotate synchronously and in the same direction, the two second bevel gears 76 rotate the two lead screws 75, the two lead screws 75 cause the two second guide blocks 74 to slide horizontally along the inner walls of the corresponding second guide grooves 73, the two second guide blocks 74 move the pushing plate 71 horizontally, and the pushing plate 71 pushes the multiple end plates in the material box 13 through the second protective pad 72, causing the multiple end plates to move horizontally along the inner wall of the material box 13. The frontmost end plate enters the guiding box 16 through the blanking groove 15 and falls into a cavity of the iron core blank through the guiding box 16, thus conveniently realizing the loading of one end plate, and further effectively improving the convenience of loading the end plates;

[0060] Meanwhile, when the sector gear 541 disengages from the second gear 56 and meshes with the third gear 59, the pushing plate 71 stops working. At the same time, the sector gear 541 drives the third gear 59 to rotate, the third gear 59 rotates the third transmission rod 58, the third transmission rod 58 rotates the first transmission rod 48 through the two transmission wheels 6 and the transmission belt 61, the first transmission rod 48 rotates the first gear 49, the first gear 49 drives the circular tooth plate 46 to rotate, the circular tooth plate 46 rotates the rotating disk 41, and the rotating disk 41 causes the two arc-shaped blocks 44 to slide along the surface of the circular guide rail 42 through the two second connecting rods 45, and at the same time rotates the iron core blank between the two limiting plates 22 synchronously. When another cavity of the iron core blank is vertically aligned with the guiding box 16, the sector gear 541 disengages from the third gear 59 and meshes with the second gear 56 again, the rotating disk 41 stops rotating, and the pushing plate 71 works again. The multiple end plates are pushed by the pushing plate 71 one by one into the multiple cavities of the iron core blank, thus conveniently realizing the intermittent rotation of the iron core blank and the continuous loading of the end plates, and further effectively improving the convenience of loading the end plates. At the same time, the working time of manually loading the end plates is effectively reduced, and at the same time, the efficiency of subsequent rubber coating of the motor iron core is effectively improved.
