[0048] The present invention adopts the inner positioning technology, and takes the inner circle of the punching sheet 3, the lower wire groove, and the through screw hole as the positioning reference for the stacking; the stacking platform plate is controlled to rotate around its axis by the rotating device 4. When stacking, the operator can sit in a fixed position, and the rotating device 4 controls the stacking platform plate to rotate around its axis, and cooperates with the positioning device 2 to realize the stacking of the punching sheet 3, which greatly reduces the labor intensity of the operator and improves the production efficiency;

[0049] In some possible implementations, in order to effectively realize the positioning of the punching sheets 3, the stacking of the punching sheets 3 meets the requirements;

[0050] like Figure 1 , Figure 2 As shown, the positioning device 2 includes a positioning plate 21 coaxially arranged and installed on the stacking platform plate 1 , and a plurality of positioning components uniformly arranged along the circumference of the stacking platform plate 1 and installed outside the positioning plate 21 .

[0052] In some possible implementations, in order to effectively realize the verticality of the stacking of the punching sheets 3 and the effective positioning of the inner circle of the punching sheets 3;

[0053] like Figure 3 As shown, the positioning assembly includes a groove sample rod 22 installed on the positioning plate 21 and with the other end located on the stacking platform plate 1, and an inner diameter positioning block 23 installed on the outside of the positioning plate 21 and located on both sides of the groove sample rod 22.

[0054] The groove sample rod 22 is installed on the positioning plate 21 and the lamination platform plate 1. It protrudes from the lamination platform plate 1 and cooperates with the lower wire groove of the punching sheet 3 to realize the positioning of the lower wire groove.

[0055] The inner diameter positioning block 23 is installed outside the positioning plate 21 to realize the positioning of the inner circle of the punching sheet 3.

[0056] In some possible implementations, in order to effectively realize the connection between the positioning plate 21 and the stacking platform plate 1, the positioning plate 21 can rotate along with the rotation of the stacking platform plate 1 under the driving of the rotating device 4;

[0057] like Figure 1 , Figure 2 As shown, the positioning plate 21 is provided with a groove 211 for installing the groove template, and the stacking platform plate 1 is provided with a groove 2 11 corresponding to the groove 211, and the groove 1 211 and the groove 2 11 cooperate with each other to form a groove for installing the groove sample rod 22.

[0059] Preferably, each group of grooves 11 arranged on the lamination platform 1 can be composed of grooves of multiple structural forms; the purpose of such arrangement is to effectively improve the versatility of the lamination platform 1. According to the different sizes of the punching sheets 3, the groove templates are installed in different grooves to position the punching sheets 3 of different sizes.

[0060] In some possible implementations, in order to effectively implement the installation of the inner diameter positioning block 23;

[0061] like Figure 2 As shown, a U-shaped groove 212 is provided on the outer side of the positioning plate 21 , and the inner diameter positioning block 23 is installed in the U-shaped groove 212 .

[0068] The inner diameter positioning block 23 is set to an unequal cross-section structure, and the area of ​​the side close to the inner circle of the punching sheet 3 is smaller, so that the inner circle of the punching sheet 3 can be abutted and positioned while effectively reducing the friction between the inner diameter positioning block 23 and the inner circle of the punching sheet 3.

[0069] In the present invention, different groove sample rods 22 and inner diameter positioning blocks 23 can be replaced according to the needs of lamination to meet the lamination requirements of punching sheets 3 of different sizes.

[0074] In some possible implementations, in order to accommodate the use of operators of different heights;

[0075] An adjustable support frame 5 is installed at the bottom of the stacking platform plate 1 .
