In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.
[0053] Please also read Figures 1 to 10 The transformer silicon steel sheet lamination device provided by the present application is now described. The transformer silicon steel sheet lamination device comprises a base 1, two loading boxes 2 and two pushing members 3.
[0054] The base 1 can be fixed on any horizontal plane by means of a clamp, a threaded connection structure, etc., so that its upper side is in a horizontal state. The upper side of the base 1 has a limit assembly 4 for connecting with the winding 7; when the limit assembly 4 is connected with the winding 7, the winding 7 cannot move relative to the base 1 to prevent the winding 7 from shifting and affecting the product quality; and the socket of the winding 7 is oriented in the horizontal direction. In this embodiment, for the convenience of description, the socket of the winding 7 is defined as oriented in the left and right direction.
[0055] The two loading boxes 2 are respectively arranged on the left and right sides of the limiting assembly 4, and each loading box 2 adopts a structure that is through in the up-down direction, and the operator can fill the silicon steel sheet 8 through the upper opening of the loading box 2. The lower side of each loading box 2 has two material guide tables 21 arranged side by side on the upper side of the base 1 in the front-to-back direction; in each loading box 2, the silicon steel sheet 8 at the bottom can be connected to the upper surface of the material guide table 21, so that the material guide table 21 supports the silicon steel sheet in the loading box 2. Each material guide table 21 is connected to the lower side of the loading box 2 through a pad 22. By adopting the above structure, a gap suitable for a silicon steel sheet 8 at the bottom of the loading box 2 to pass can be formed between the loading box 2 and the material guide table 21; and each material guide table 21 extends to the outside of the loading box 2 toward the limiting assembly 4, and its protruding part is used to support the silicon steel sheet 8 discharged from the inside of the loading box 2.
[0056] The two pushers 3 are respectively arranged on the lower sides of the two loading boxes 2, and the two pushers 3 are slidably connected to the upper side of the base 1 along the left and right directions; the upper side of each pusher 3 is coplanar with the lower side of the loading box 2, and there is a driving component between the two pushers 3 for driving them to move.
[0057] Among them, when the pusher 3 moves toward the limiting assembly 4, the pusher 3 can push the silicon steel sheet 8 at the bottom in the loading box 2 to the guide platform 21 outside the loading box 2; and when the pusher 3 moves toward the limiting assembly 4 and there is already a silicon steel sheet 8 on the guide platform 21 outside the loading box 2, the silicon steel sheet 8 connected to the pusher 3 can push the silicon steel sheet 8 originally outside the loading box 2 to be inserted into the winding 7. In addition, by presetting the length of the pusher 3, the following technical effects can be achieved: when the pusher 3 pushes the silicon steel sheet 8, the upper side surface of the pusher 3 can support the silicon steel sheet 8 in the loading box 2 to prevent the silicon steel sheet 8 from falling and affecting the movement of the pusher 3 back to the winding 7.
[0058] The transformer silicon steel sheet stacking device provided in the present application is configured to fix the base 1 on a horizontal plane, and place two groups of silicon steel sheets 8 into two loading boxes 2 on the base 1, respectively, wherein the opening directions of the two groups of silicon steel sheets 8 are placed in opposite directions; when performing the stacking operation, the winding 7 to be assembled with the silicon steel sheets 8 is placed on the limiting assembly 4 between the two loading boxes 2, and then the silicon steel sheets 8 inside the two loading boxes 2 are driven by two pushing members 3 respectively slidably arranged on the upper side of the base 1 and connected to the driving assembly, pass through the gap formed between the loading box 2 and the guide table 21, and be inserted into the winding 7.
[0059] Compared with the prior art, the transformer silicon steel sheet stacking device proposed in the present application optimizes the cross-stacking process of the silicon steel sheets 8, liberates manpower, improves the stacking efficiency of the silicon steel sheets 8, avoids the influence of human factors, and ensures the stability of product quality.

[0061] Among them, the lower side surface of the pressure plate 23 adopts an inclined surface, and the inclined surface is inclined downward along the direction of the loading box 2 toward the limit assembly 4; when the silicon steel sheet 8 moves to the outside of the loading box 2, the lower side surface of the pressure plate 23 can connect with the silicon steel sheet 8 and cause the elastic member 24 to undergo elastic deformation.
[0062] A guide channel for the silicon steel sheet 8 to pass through is formed between the pressure plate 23 and the guide platform 21; by adopting the above technical solution, when the pusher 3 pushes the silicon steel sheet 8 and the silicon steel sheet 8 originally on the outside of the loading box 2 is inserted into the winding 7, the silicon steel sheet 8 is restricted by the guide channel and can move stably without skewing, thereby ensuring the accuracy of the silicon steel sheet 8 during the stacking process.
[0063] In some embodiments, please refer to Figures 1 to 7 As a specific implementation of the transformer silicon steel sheet lamination device provided in the present application, the elastic member 24 includes a bolt 241 and a spring 242 .
[0064] The bolt 241 is set on the material guide platform 21, the axial direction of the bolt 241 is parallel to the up and down direction, and the bolt 241 is threadedly connected to the upper side of the material guide platform 21; the bolt 241 adopts a model with a long screw rod. After the bolt 241 is completely screwed into the material guide platform 21, a part of the screw rod is located above the material guide platform 21.
[0065] The spring 242 is sleeved on the outer circumference of the bolt 241 , and the upper and lower ends of the spring 242 are respectively connected to the head of the bolt 241 and the upper side of the pressure plate 23 .
[0066] By adopting the above technical solution, the operator can adjust the distance between the head of the bolt 241 and the pressure plate 23 by rotating the bolt 241, thereby adjusting the deformation of the spring 242, and correspondingly adjusting the pressure overcome by the silicon steel sheet 8 when passing between the pressure plate 23 and the material guide table 21; therefore, the operator can adjust the required pressure according to the thickness of the silicon steel sheet 8.
[0067] It is necessary to add that, if Figure 1 and Figure 2 As shown, the pressing plate 23 has a reserved hole extending in the up-down direction, and the bolt 241 is arranged through the reserved hole and connected to the pressing plate 23 through the spring 242 .

The sliding part 31 can be slidably connected to the base 1 through a linear bearing or a linear guide rail; the upper side of the sliding part 31 is coplanar with the lower side of the loading box 2, and it is transmission-connected to the driving assembly.
[0070] A plurality of push rods 32 are arranged at intervals along the front-to-back direction on one side of the sliding portion 31 facing the limiting assembly 4 , with their axial directions all being parallel to the left-to-right direction, and all being fixedly connected to the sliding portion 31 .
[0071] Among them, the upper side surface of each push rod 32 is coplanar with the upper side surface of the sliding part 31, or is located between the upper side surface of the sliding part 31 and the upper side surface of the material guide platform 21; when the sliding part 31 moves toward the limit assembly 4, multiple push rods 32 can abut against the silicon steel sheet 8 at the bottom of the loading box 2, and push the silicon steel sheet 8 at the bottom to the outside of the loading box 2; when the push rod 32 pushes the silicon steel sheet 8 to the outside of the loading box 2, the remaining silicon steel sheets 8 inside the loading box 2 fall to the bottom of the loading box 2 under the influence of their own gravity, and at this time the sliding part 31 supports the silicon steel sheet 8 in the loading box 2.
[0072] By adopting the above technical solution, the sliding part 31 performs linear reciprocating motion under the drive of the driving component. Every time the sliding part 31 completes a reciprocating motion, the push rod 32 can complete the pushing of the silicon steel sheet 8, thereby realizing the automation of the pushing of the silicon steel sheet 8, and the reciprocating speed of the propulsion member can be adjusted by adjusting the power of the driving component.

[0075] The bracket 42 is arranged on the upper side of the positioning box 41, which is fixedly connected to the upper side of the base 1 and has a pressure rod 43; the pressure rod 43 is located on the upper side of the bracket 42 and is also provided with a handle extending radially outward, and the handle is used for the operator to hold and rotate.
[0076] The axial direction of the pressure rod 43 is parallel to the up-down direction, and the pressure rod 43 is threadedly connected to the bracket 42 along the up-down direction to abut against the upper end of the winding 7 .
[0077] By adopting the above technical solution, the adaptability of the device is improved, and the operator can replace the size of the positioning box 41 according to product requirements; after the winding 7 is embedded in the positioning box 41, the operator can rotate the pressure rod 43 to move the bottom of the pressure rod 43 downward until it abuts against the upper end surface of the winding 7, thereby completing the fixation of the winding 7 in all directions, improving the stability during the lamination operation, and ensuring product quality.

[0079] By adopting the above technical solution, since the rubber pad 44 is made of a relatively soft material, the rubber pad 44 can prevent the lower end of the pressure rod 43 from scratching the winding 7 and affecting the quality of the transformer product.

[0085] When one of the silicon steel sheets 8 is inserted into the winding 7 , the driving assembly drives the push member 6 to move away from the silicon steel sheet 8 , so that the inclined silicon steel sheet 8 is transformed into a flat state and connected with the inserted silicon steel sheet 8 .
