[0020] The power unit comprises the electric guide rails 10, the electric sliding blocks 11 and the connecting rods 12; the T-shaped frame 9 is provided with two electric guide rails 10 distributed in front and back; each electric guide rail 10 is slidably connected with an electric sliding block 11; the two electric sliding blocks 11 are fixedly connected with the connecting rod 12; the connecting rod 12 is fixedly connected with two corresponding top rods 13.

[0021] The top rod 13 is provided with a rubber pad on the side facing the material frame 14, so as to avoid damaging the E-shaped silicon steel sheet body 002 when the top rod 13 pushes the E-shaped silicon steel sheet body 002.

[0022] The working steps of the above embodiment are as follows: First, the E-shaped silicon steel sheet body 002 is stacked and then conveyed to the vicinity of the device through the external conveying belt; all the electric actuators II 15 are controlled to extend, synchronously driving the movable plates 1402 to move away from the T-shaped frame 9, so that the volume of the material frame 14 is expanded, facilitating the placement of the E-shaped silicon steel sheet body 002; then the external mechanical hand clamps the stacked E-shaped silicon steel sheet body 002 and then transfers it to the material frame 14; the same operation is performed on the other material frame 14; the E-shaped openings of the E-shaped silicon steel sheet bodies 002 in the two material frames 14 face each other; then all the electric actuators II 15 are controlled to contract, synchronously driving the two movable plates 1402 to move away from each other; each movable plate 1402 contacts and pushes the E-shaped silicon steel sheet body 002 in the corresponding material frame 14, so as to realize the pushing and alignment of the E-shaped silicon steel sheet body 002; then the external mechanical hand is controlled to transfer a coil winding 001 above the limiting groove 7001, so that the middle through holes of the coil winding 001 correspond to the material frames 14; then the external mechanical hand is controlled to slowly lower the coil winding 001; after the lower part of the coil winding 001 enters the limiting groove 7001, the infrared sensor in the limiting groove 7001 detects the coil winding 001; then all the electric actuators I 8 are controlled to extend, so that the extension parts of all the electric actuators I 8 press on the coil winding 001, clamping the coil winding 001, thereby fixing the coil winding 001, thus completing the preparation work for the core lamination processing.

[0023] Then, due to the difference in the height position of the two material frames 14, at this time, the position of the left material frame 14 is lower than the position of the right material frame 14 by the thickness of the E-type silicon steel sheet body 002, so when the E-type silicon steel sheet body 002 is inserted into the coil winding 001, the left E-type silicon steel sheet body 002 is inserted first, so the left two electric sliding blocks 11 are controlled to move on the corresponding electric guide rails 10 respectively, so that the electric sliding block 11 moves in the direction of the material frame 14, synchronously driving the connecting rod 12 and the corresponding parts on it to move, so that the corresponding top rod 13 moves in the direction of the coil winding 001, the two top rods 13 on the left side contact the lowest E-type silicon steel sheet body 002 in the material frame 14 together, with the movement of the electric sliding block 11, the lowest E-type silicon steel sheet body 002 is moved synchronously, the lowest E-type silicon steel sheet body 002 moves from the gap between the bottom of the movable plate 1402 and the material frame 14 to the direction close to the coil winding 001 under the cooperation of the roller 1401, until the middle convex part of the E-type silicon steel sheet body 002 is inserted into the center hole of the coil winding 001, then the left electric sliding block 11 is controlled to reset, when the left top rod 13 exits the material frame 14, the E-type silicon steel sheet body 002 stacked in the left material frame 14 is displaced downward by the thickness of an E-type silicon steel sheet body 002 under the action of gravity, until the lowest E-type silicon steel sheet body 002 contacts the roller 1401, and the right top rod 13 pushes the corresponding E-type silicon steel sheet body 002 out and inserts the right E-type silicon steel sheet body 002 into the coil winding 001, so that the right E-type silicon steel sheet body 002 is pressed at the gap of the left E-type silicon steel sheet body 002, at this time, a simple stacking operation is completed.

[0024] On the basis of the above simple stacking operation, control starts all the motors 5, the output shaft of the motor 5 drives the corresponding threaded rod 2 to rotate, and then cooperates with all the guide rods 3 to synchronously drive the connecting frame 6 and the corresponding parts thereon to move downward along the threaded rod 2 and the guide rod 3, so that the mounting frame 7 drives the electric actuator I 8 and the clamped coil winding 001 to move downward, and after the coil winding 001 moves downward by a distance of the thickness of the E-shaped silicon steel sheet body 002, the control closes all the motors 5, and then repeats the above simple stacking operation, thereby alternately performing the stacking operation and the operation of lowering the coil winding 001, that is, the operation of quickly stacking the coil winding 001, until the through hole of the coil winding 001 is filled with the E-shaped silicon steel sheet body 002 in the middle part, at which time the lamination operation of the silicon steel sheet is completed, and then when the connecting frame 6 moves to the lower end of the threaded rod 2, all the electric actuators I 8 are controlled to retract, thereby releasing the fixation of the coil winding 001, and then the external mechanical hand can clamp and transfer the coil winding 001, place the completed stacked coil winding 001 on the external conveying belt, and convey it to the next process for processing, and control all the motors 5 to reverse, thereby synchronously resetting the connecting frame 6 and the corresponding parts thereon.

[0025] On the basis of the above operation, after the E-shaped silicon steel sheet body 002 is pushed into the coil winding 001, the ejector rod 13 and the corresponding parts thereon are reset, and then during the process of lowering the coil winding 001, the E-shaped silicon steel sheet body 002 is in an unfixed state, and during the lowering process, the E-shaped silicon steel sheet body 002 will displace, causing the E-shaped silicon steel sheet body 002 to exit from the center hole of the coil winding 001. Therefore, after completing the complete stacking operation of the coil winding 001, the connecting frame 6 and the corresponding parts thereon are controlled to reset upward, synchronously driving the completed stacked coil winding 001 upward, and then all the electric actuators II 15 are controlled to extend, synchronously driving the corresponding movable plates 1402 to move, and the two movable plates 1402 move toward each other, approach and push the E-shaped silicon steel sheet body 002 on the coil winding 001, thereby realizing the regulation of the E-shaped silicon steel sheet body 002, pushing the displaced E-shaped silicon steel sheet body 002 back to be flat, effectively improving the stacking precision, constructing an efficient and uniform magnetic circuit, ensuring that the transformer has good magnetic permeability and low loss characteristics, avoiding the situation that the displacement of the E-shaped silicon steel sheet body 002 causes the increase of eddy current loss and the increase of local heat generation, and causing the transformer to be damaged.

[0026] Second embodiment On the basis of the first embodiment, according to Figure 1 , Figure 2 , Figure 6 and Figure 7As shown, several balls are evenly arranged on the upper and lower parts of the push rod 13 to reduce the frictional heat generated between the push rod 13 and the material frame 14 and other E-type silicon steel sheet bodies 002.

[0027] It also includes a circular plate 101 and a conduit 102; the upper part of all guide rods 3 and all protective shells 4 are fixedly connected to the circular plate 101; the bottom of the circular plate 101 contacts the mounting frame 7; a square groove 10101 is opened in the middle of the circular plate 101; the square groove 10101 is larger than the limiting groove 7001; an air chamber 10102 is opened inside the circular plate 101; several air holes 10103 are opened on the air chamber 10102; all air holes 10103 are connected to the square groove 10101; the air chamber 10102 is connected to the conduit 102.

[0028] Each vent 10103 is equipped with a dustproof screen to intercept dust and impurities in the air.

[0029] The working steps of the above embodiments are as follows: Based on the first embodiment, considering that the push rod 13 needs to reciprocate at high speed to push each E-type silicon steel sheet body 002, and also needs to control the connecting frame 6 to move downward on the threaded rod 2 and guide rod 3, the moving parts rapidly heat up under the action of mechanical friction as the lamination process proceeds at high speed. In particular, the moving parts of this device are concentrated in the central region, where the temperature rise is significant and heat dissipation is insufficient, which in turn affects the operating accuracy. During the lamination process, the operating accuracy directly affects the lamination accuracy. For example, when the motor 5 and the threaded rod 2 are working continuously, the friction between the connecting frame 6 and the threaded rod 2 and guide rod 3 causes the temperature of the connecting frame 6 and its corresponding components to rise, and the surface roughness of the threaded rod 2 to increase, affecting the smoothness and responsiveness of the operation. The speed of movement can lead to inaccurate movement accuracy of the connecting frame 6. This accuracy directly affects the descent accuracy of the coil winding 001. Consequently, the descent height of the coil winding 001 may be insufficient to cover the thickness of two E-type silicon steel sheet bodies 002. This causes subsequent stacking of the E-type silicon steel sheet bodies 002 to obstruct the movement of the already inserted coil winding 001, jamming the device and severely impacting processing progress. Conversely, if the descent height of the coil winding 001 exceeds the thickness of two E-type silicon steel sheet bodies 002, subsequent E-type silicon steel sheet bodies 002 may fall downwards when pushed into the center hole of the coil winding 001, resulting in... The uncertain stacking spacing severely affects the stacking accuracy of the E-type silicon steel sheet body 002, thereby increasing the hysteresis loss and eddy current loss of the transformer core. To address this, several ball bearings are installed above and below the push rod 13. After one E-type silicon steel sheet body 002 is pushed out of the material frame 14, the remaining E-type silicon steel sheet bodies 002 in the material frame 14 press against the push rod 13. At this point, the push rod 13 needs to be pulled out of the material frame 14 and reset. The ball bearings on the push rod 13 contact the E-type silicon steel sheet body 002 and the roller 1401, effectively reducing the temperature rise caused by friction of the push rod 13. Furthermore, a circular plate 101 is added between the mounting frame 7 and the material frame 14, and the conduit 102 is connected to an external air pump. The external air pump pumps air from the air chamber 10102 through the conduit 102. When the air chamber 10102 is under negative pressure, outside air enters through the air vent 10103. Since the air vent 10103 is located on the side wall of the square slot 10101, the outside air will gather towards the center of the device during its flow, exchanging heat with the device and thus cooling it. The heat generated by the device, along with the outside air, enters the air chamber 10102 through the air vent 10103. Then, an external air pump draws the air out of the air chamber 10102 through the conduit 102. This active suction cooling process prevents heat buildup that could reduce the precision of moving parts and consequently, the stacking accuracy.This leads to an increase in the hysteresis loss and eddy current loss of the transformer core.
