[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. By setting up an alternating leveler, the trapezoidal leveling rods of the alternating leveler move from the top center of the silicon steel sheet to the end to level it, which can effectively eliminate unevenness problems such as warping and wrinkles of the silicon steel sheet, and make the silicon steel sheets fit tightly together. Through the alternating work of multiple sets of trapezoidal leveling rods, the silicon steel sheets during the stacking process can be continuously flattened to ensure that each layer of silicon steel sheets can be stacked flat, thereby improving the overall flatness and tightness of the iron core. When one set of trapezoidal leveling rods is about to approach another set, another set of electric push rods is activated to move the trapezoidal leveling rods that were originally pressing on both ends of the silicon steel sheet upwards, while driving another set of trapezoidal leveling rods to perform corresponding actions. This alternating working method ensures the continuity of the leveling operation of stacked silicon steel sheets, avoids the time wasted due to waiting for equipment adjustment, and thus improves the overall practicality of the device.

[0016] 2. By setting up an obstacle avoidance component, when the rectangular sliding rod driven by the electric push rod at the output end moves the trapezoidal leveling rod upward to separate from the silicon steel sheet at the bottom, the rectangular sliding rod will drive the second ball rod to move upward synchronously. When the second ball rod contacts the inner inclined surface of the bending block, it pushes the first spur rack towards the second spur gear under the drive of the inner inclined surface of the bending block. This drives the second spur gear to drive the trapezoidal leveling rod to rotate away from the silicon steel sheet through the connecting rod. When the electric push rod stops moving, the trapezoidal leveling rod is stored in one side of the second fixed seat, so that the two sets of trapezoidal leveling rods can automatically avoid each other during relative movement. This ensures the stable operation of the device. The automatic obstacle avoidance function makes the movement of the trapezoidal leveling rod smoother, without the need for additional time to adjust or avoid collisions, thus improving the leveling efficiency of the silicon steel sheet. The time for each leveling operation is shortened, and more leveling actions can be completed per unit time, thereby improving the overall production efficiency of the transformer core.

[0017] 3. By setting up the cooperation of parts such as the first spur gear, when the second slider drives the trapezoidal smoothing rod to move towards the edge of the silicon steel sheet, when the first spur gear contacts the second spur rack, it can drive the second spur rack to drive the worm gear to rotate, thereby driving the worm wheel to drive the electric push rod to rotate through the rectangular sliding rod. When the first spur gear separates from the second spur rack, the angle of rotation of the trapezoidal smoothing rod matches the angle at the edge of the silicon steel sheet. This allows for adaptive pressing of the corners of the silicon steel sheet without affecting the smoothing operation of the silicon steel sheet in other positions. It ensures that the corners of the silicon steel sheet fit tightly with other parts, effectively eliminating gaps or unevenness at the corners, thereby improving the overall practicality of the device.

[0018] 4. By setting up a calibration auxiliary component, when the trapezoidal leveling rod moves downward to press the silicon steel sheet, the first spherical rod contacts the inner inclined surface of the inclined block. Under the action of the inner inclined surface of the inclined block, the first spherical rod is pushed to move the calibration block towards the end of the silicon steel sheet. This can achieve the calibration of the position of the silicon steel sheet, so that the silicon steel sheet can be closely attached to the silicon steel sheet located in the center position, which greatly improves the stacking accuracy of the iron core and reduces the iron core quality problems caused by the positional deviation of the silicon steel sheet.

[0034] First, four alternating levelers can be arranged around the support base 2, so that the silicon steel sheets 3 at different positions can be leveled respectively;

[0035] For details on how the silicon steel sheets 3 are stacked, please refer to the published patent document "CN218602248U". Since this solution does not improve in this respect, it is not elaborated in detail here.

[0036] The inner leveling structure of the two upper and lower fixed seats 6 can be divided into an upper leveling structure and a lower leveling structure. Since the upper and lower leveling structures are staggered vertically, the two second sliders 12 will not be obstructed during lateral movement. When the silicon steel sheets 3 need to be leveled during stacking, a set of trapezoidal leveling rods 5 in the lower leveling structure presses down on both ends of the bottom silicon steel sheet 3. When the second silicon steel sheet 3 is stacked, as it reaches the top of the already leveled silicon steel sheet 3, the two trapezoidal leveling rods 5 in the lower leveling structure initially adhere to the top of one end of the silicon steel sheet 3. Then, the two electric push rods 15 in the upper leveling structure are activated. The output end of the electric push rod 15... The second connecting seat 16 drives the trapezoidal smoothing rods 5 downwards, causing a set of trapezoidal smoothing rods 5 in the upper smoothing structure to press against the top center of the silicon steel sheet 3, making the two silicon steel sheets 3 stick together. Then, a second drive motor 14 in the upper smoothing structure is activated. The output end of the second drive motor 14 drives the bidirectional threaded screw 11 to rotate, thereby driving the two trapezoidal smoothing rods 5 located at the center of the silicon steel sheet 3 to move towards the ends of the silicon steel sheet 3, thus realizing the smoothing operation of the silicon steel sheet 3. When a set of trapezoidal smoothing rods 5 in the upper smoothing structure is about to approach a set of trapezoidal smoothing rods 5 in the lower smoothing structure, a set of electric push rods 15 in the lower smoothing structure is activated, thereby driving the trapezoidal smoothing rods that were originally pressing against both ends of the silicon steel sheet 3. The flat rod 5 moves upward until it separates from the silicon steel sheet 3 attached to the top. Then, a second drive motor 14 in the lower leveling structure is activated, which drives another bidirectional threaded screw 11 to rotate, thereby driving another set of second sliders 12 to move towards the center of the silicon steel sheet 3. At this time, a first drive motor 8 drives a unidirectional threaded screw 7 to rotate, thereby driving a set of trapezoidal leveling rods 5 in the lower leveling structure to move upward a certain distance, so as to level the next stack of silicon steel sheets 3. Repeat the above operation to level the stacked silicon steel sheets 3. The trapezoidal leveling rods 5 of the alternating leveler move from the top center of the silicon steel sheet 3 to the end to level it, which can effectively eliminate unevenness such as warping and wrinkles of the silicon steel sheet 3. The problem is that the silicon steel sheets 3 are tightly bonded together. Through the alternating work of multiple sets of trapezoidal smoothing rods 5, the silicon steel sheets 3 during the stacking process can be continuously flattened, ensuring that each layer of silicon steel sheets 3 can be stacked flat, improving the overall flatness and tightness of the iron core. When a set of trapezoidal smoothing rods 5 in the upper smoothing structure is about to approach a set of trapezoidal smoothing rods 5 in the lower smoothing structure, a set of electric push rods 15 in the lower smoothing structure is activated, causing the trapezoidal smoothing rods 5 that were originally pressing on both ends of the silicon steel sheets 3 to move upward, while driving a set of trapezoidal smoothing rods 5 in the lower smoothing structure to perform corresponding actions. This alternating working method ensures the continuity of the smoothing operation of the stacked silicon steel sheets 3, avoiding the time wasted due to waiting for equipment adjustment, thereby improving the overall practicality of the device.

[0037] When the rectangular sliding rod 17, driven by the output end of the electric push rod 15, moves the trapezoidal smoothing rod 5 upward and separates it from the silicon steel sheet 3 at the bottom, the rectangular sliding rod 17 will drive the second ball rod 35 to move upward synchronously. When the second ball rod 35 contacts the inner inclined surface of the bending block 32, it will push the first spur rack 34 to move towards the second spur gear 31 under the drive of the inner inclined surface of the bending block 32. This will drive the second spur gear 31 to rotate the trapezoidal smoothing rod 5 away from the silicon steel sheet 3 through the connecting rod 18. When the electric push rod 15 stops moving, the trapezoidal smoothing rod 5 is stored in one side of the second fixed seat 6, so that the two sets of trapezoidal smoothing rods 5 can automatically avoid each other during relative movement. This can ensure that the device can operate stably. The automatic avoidance function makes the movement of the trapezoidal smoothing rod 5 smoother, without the need for additional time to adjust or avoid collisions, thus improving the smoothing efficiency of the silicon steel sheet 3. The time for each smoothing operation is shortened, and more smoothing actions can be completed per unit time, thereby improving the overall production efficiency of transformer cores.

[0038] When the second slider 12 moves the trapezoidal smoothing rod 5 towards the edge of the silicon steel sheet 3, when the first spur gear 29 contacts the second spur rack 39, it can drive the second spur rack 39 to drive the worm gear 26 to rotate, thereby driving the worm wheel 27 to drive the electric push rod 15 to rotate through the rectangular sliding rod 17. When the first spur gear 29 separates from the second spur rack 39, the angle of rotation of the trapezoidal smoothing rod 5 matches the angle at the edge of the silicon steel sheet 3. This allows for adaptive pressing of the corners of the silicon steel sheet 3 without affecting the smoothing operation of other parts of the silicon steel sheet 3, ensuring that the corners of the silicon steel sheet 3 fit tightly like other parts, effectively eliminating gaps or unevenness at the corners, and thus improving the overall practicality of the device.

[0039] Please see Figures 1 to 11 The calibration auxiliary component is located at the bottom of the trapezoidal smoothing rod 5 and is used to move the silicon steel sheet 3 for lateral calibration. The calibration auxiliary component includes a first suspension seat 22 fixedly connected to the bottom of the trapezoidal smoothing rod 5. A first spherical rod 21 is slidably connected to the inner side of the first suspension seat 22. One end of the first spherical rod 21 passes through the outer wall of the first suspension seat 22 and is fixedly connected to a calibration block 20. A connecting spring 23 is installed between the calibration block 20 and the first suspension seat 22. The calibration auxiliary component also includes a connecting rod 24 fixedly connected to the outer wall of the rotating shaft 41. An inclined block 25 is fixedly connected to the inner side of the connecting rod 24. One end of the first spherical rod 21 is set to be spherical.

[0040] As the trapezoidal leveling rod 5 moves downward to press the silicon steel sheet 3, the first spherical rod 21 contacts the inner inclined surface of the inclined block 25. Under the action of the inner inclined surface of the inclined block 25, the first spherical rod 21 is pushed to drive the calibration block 20 to move towards the end of the silicon steel sheet 3. This can achieve the calibration of the position of the silicon steel sheet 3, so that the silicon steel sheet 3 can be closely attached to the silicon steel sheet 3 located in the center position, which greatly improves the stacking accuracy of the iron core and reduces the iron core quality problems caused by the positional deviation of the silicon steel sheet 3.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
