During the use, when cutting, the carrier plate 93 is in the state of stretching out, this moment carrier plate 93 carries out the bearing to the insulating piece, promote holding power for the insulating paper, when conveniently cutting, guarantee the neat of tangent plane, after cutting, when pressing down the insulating piece after cutting, unblock inserted bar 91 moves down this moment, round hole through on mounting box 92 inserts, the arcwall face and the arc head 99 contact of unblock inserted bar 91 bottom, along with the insertion of unblock inserted bar 91, drive arc head 99 and linkage plate 98 to move towards the direction of keeping away from fly leaf 55, until carrier plate 93 shrink to mounting box 92, synchronous drive pull rod 97 and the slider 95 on it moves towards the direction of keeping away from fly leaf 55, synchronous compression No. two spring 96, at this moment loosen the bearing of carrier plate 93 to the insulating piece, at this moment along with the pushing down of fly leaf 55, the insulating piece after cutting is pressed into spacing groove 18 inside, when fly leaf 55 rises, synchronous drive unblock inserted bar 91 rises, loosen the extrusion of unblock inserted bar 91 to arc head 99, under the effect of the restoring force of No. spring 96 again to stretch out to the insulating piece's of carrier plate 93.
Meanwhile, the reciprocating lifting piece 59 can realize intermittent rotation of the motor rotor, so that the motor rotor can be conveniently and circumferentially rotated to sequentially insert, the specific principle is that the clamping block 20 is in unidirectional rotation under the action of the torsion spring 22, when the lifting assembly 3 lifts the motor rotor upwards, the arc surface of the clamping block 20 is attached to the outer wall of the motor rotor, when the motor rotor rises to be attached to the bottom of the upper cover 19, the clamping block 20 is just clamped into a winding groove of the motor rotor, the accurate positioning of the motor rotor is realized, and a top notch of the motor rotor is just positioned at the left side of the limiting groove 18,
At this time, along with the downward movement of the movable plate 55, the fixed head 57 and one end of the rocker 591 are synchronously driven to move downwards, the bump 592 is synchronously driven to move downwards, then the top block 595 and the guide rod 597 thereon are driven to move downwards, and meanwhile, the lifting plate 598 and the fixed pin 21 and the clamping block 20 thereon are driven to move downwards, and when the clamping block 20 moves downwards, the movable plate 55 indirectly drives the clamping block 20 to move upwards under the restoring force of the spring 596, so that the up-and-down reciprocating movement of the clamping block 20 is realized through the reciprocating lifting piece 59;
The clamping block 20 is of a gradually enlarged structure near the fixing pin 21, the clamping block 20 is of a detachable design, when different clamping blocks 20 are replaced according to different motor rotors, the top of the clamping block 20 is a straight surface and pushes the motor rotors to rotate by a certain angle, at the moment, the slots into which the insulating sheets are inserted are rotated out of the working positions, the next slots into which the insulating sheets are not inserted are rotated into the working positions, at the moment, the root parts of the gradually enlarged clamping block 20 are contacted with the edges of the lifting seat 31, the clamping block 20 is driven to overcome the elasticity of the torsion spring 22 by extrusion and deflect towards the direction far away from the motor rotors, at the moment, the clamping block 20 is clamped into the winding grooves of the motor rotors again under the action of the elasticity of the torsion spring 22 when the clamping block 20 moves downwards, and the steps are repeated, so that the motor rotors are circumferentially rotated, the insulating sheets are conveniently and the motor rotors are not required to be driven to rotate by the motor.
Referring to fig. 12, a method for inserting a rotor of a motor includes the following steps:
S1, rotor feeding, namely firstly, conveying a motor rotor from front to back by using a conveyor 2, conveying the motor rotor to the middle of the conveyor 2, and stopping, lifting the motor rotor by using a lifting assembly 3 until the top of the motor rotor is attached to the bottom of an upper cover 19, and then, precisely clamping a clamping block 20 into a winding groove of the motor rotor to accurately position the motor rotor, wherein a notch at the top of the motor rotor is precisely positioned at the left side of a limiting groove 18, so that feeding of the motor rotor is completed;
S2, after the feeding of the motor rotor is completed, the automatic feeding machine conveys the insulating tape along the guide groove 14 to feed, after the feeding is completed, under the drive of the transmission assembly 6, when the flywheel 64 positioned at the front side rotates, the first limiting pin 43 and the first connecting rod 42 on the first limiting pin are driven to reciprocate up and down through the cam groove on the flywheel 64, the first fixing arm 44 and the slitting knife 45 on the first fixing arm are synchronously driven to reciprocate up and down, when the slitting knife 45 moves downwards, the slitting of the insulating tape is realized, when the slitting knife 45 ascends, the slitting knife 45 is reset, and the insulating tape is cut into fixed lengths by the slitting assembly 4;
S3, in the cutting process of the step, when the first fixed arm 44 and the slitting knife 45 move downwards, the pressing arm 81 and the second pressing plate 82 thereon are synchronously driven to move downwards, the air bag 83 is compressed, air in the air bag 83 is conveyed to the air nozzle 87 through the air pipe 84 and is blown out through the air nozzle 87, the blown air blows to the slot of the motor rotor for cleaning, so that scraps and impurities in the slot of the motor rotor are effectively removed, the influence of the impurities and scraps on the insertion of the insulating sheet is avoided, and the smooth insertion of the insulating sheet is ensured;
S4, aligning the inserting sheet, namely after blowing cleaning is completed, under the drive of a transmission assembly 6, when the insulating sheet is cut, under the drive of a flywheel 64 positioned at the rear side, a second connecting rod 52 and a second fixing arm 54 on the second connecting rod reciprocate up and down, synchronously drive a movable plate 55 and a mounting arm 58 on the movable plate 55 to reciprocate up and down, then drive a first pressing plate 56 to reciprocate up and down, when the first pressing plate 56 moves down, the insulating sheet after cutting is pressed down into a limit groove 18, the accurate alignment between the insulating sheet and a motor rotor slot is facilitated by utilizing the limit of the limit groove 18, and then the insulating sheet is inserted into the motor rotor slot under the push of a plugboard 16, so that the inserting sheet is mounted;
S5, blanking and conveying, namely after the installation is completed, the lifting assembly 3 lowers the installed motor rotor into the conveyor 2, and the motor rotor is conveyed to the next working procedure by the conveyor 2.
