[0019] The utility model will be explained further in combination with the drawings.

[0020] As shown in a kind of iron core silicon steel sheet transverse limit alignment stacking device, including; Figure 1

[0021] Stacking table 1, its table surface is stacking operation surface, for placing silicon steel sheet 40 to carry out the stacking operation of silicon steel core 4;

[0022] Stacking and pressing part 2, vertically arranged above stacking operation surface, lower end is pressing end, and the pressing end is rolling end, for contact pressure layering stacked silicon steel sheet 40;

[0023] Transverse pushing alignment part 3, setting at the periphery of stacking operation surface, form package and push and align mechanism, specifically including:

[0024] ​Two transverse pushing and aligning parts 3 located on the two length sides of the stacking operation surface move towards each other to push the length side of the silicon steel core 4; two transverse pushing and aligning parts 3 located on the two width sides of the stacking operation surface move towards each other to push the width side of the silicon steel core 4; through the opposing pushing action of the transverse pushing and aligning parts 3, each layer of silicon steel sheets 40 is aligned towards the center during the stacking process. This invention, by setting transverse pushing and aligning parts 3 on both the length and width sides, can simultaneously align the silicon steel sheets 40 in both the length and width directions, ensuring that each layer of silicon steel sheets 40 remains aligned during the stacking process, avoiding overall deviation caused by inaccurate local alignment. This multi-dimensional alignment method significantly improves the accuracy and quality of silicon steel sheet stacking, reducing the increase in magnetic resistance and core loss caused by inaccurate alignment. Furthermore, the stacking pressing part 2 adopts a rolling end design, which can reduce damage to the surface of the silicon steel sheets 40 while pressing and aligning them, not only improving stacking efficiency but also ensuring the integrity of the silicon steel sheets.

[0025] like Figure 1 As shown, more specifically, the stacking and pressing part 2 is provided with a matching hanger 5, which is installed on the crossbeam 7 by a hanger rod 6, realizing the flexible arrangement and positioning of the stacking and pressing part 2. Several stacking and pressing parts 2 are set vertically to the corners and splices of the silicon steel sheets 40. Corners are prone to warping, and splices are prone to unevenness. By setting stacking and pressing parts 2 at both corners and splices for pressing, the stacking quality can be guaranteed.

[0026] like Figure 2 As shown, the stacked pressing part 2 includes a pressing drive unit 21, an elastic element 22 and a pressure plate 23 connected sequentially from top to bottom. The pressure plate 23 elastically presses the silicon steel sheet 40 through the elastic force provided by the elastic element 22 and the driving force provided by the pressing drive unit 21, thereby realizing the flexible pressing function. The elastic force provided by the elastic element 22 can buffer the pressing force, avoid damage to the silicon steel sheet 40, and ensure the pressing effect.

[0027] The bottom surface of the pressure plate 23 is evenly distributed with balls 24. The pressure plate 23 presses the silicon steel sheet 40 by rolling the balls 24. The arrangement of the balls 24 can greatly reduce the friction generated when pushing the silicon steel sheet 40, and avoid damage to the silicon steel sheet 40.

[0028] More specifically, the elastic element 22 is a spring telescopic rod, and its built-in spring is a pressure sensor spring 25 interlocked with the pressing drive unit 21. The pressing drive unit 21 is preferably a pressing cylinder, and the control system has a pressure holding value. When the silicon steel sheet 40 is pressed, the pressure sensor spring 25 detects that the pressure holding value has been reached, and feeds back the result to the control system. The control system then judges and controls the pressing drive unit 21 to maintain the current action and perform pressure holding on the silicon steel sheet.

[0029] like Figure 3 As shown, the lateral alignment part 3 includes a lateral drive unit 31 and a pusher plate 32 disposed on the lateral drive unit 31. The surface of the pusher plate 32 facing the silicon steel core 4 is the pushing surface. The lateral drive unit 31 drives the pusher plate 32 to feed displacement and push the silicon steel core 4, so that each layer of silicon steel sheets 40 constituting the silicon steel core 4 is aligned with the center, ensuring that each layer of silicon steel sheets always maintains an aligned state during the stacking process, reducing manual intervention, and improving stacking efficiency and consistency. The lateral drive unit 31 is preferably a linear servo slide module with high control precision.

[0030] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
