[0036] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model. It should be noted that, without conflict, the embodiments and the feature vectors in the embodiments in the present disclosure can be combined with each other arbitrarily.

[0037] In the related art, adhesive films are usually used as the bonding structure between steel plates and other material layers for laminates. However, during the hot pressing forming process, the air inside the laminate will thermally expand and cannot be discharged in time, resulting in an uneven surface of the laminate and affecting normal use.

[0038] To solve the problems existing in the related art, the embodiments of the present disclosure provide a laminar board punching device and a forming system. The laminar board punching device includes two rollers with a preset distance therebetween. The outer circumferential surface of each roller is provided with a convex structure and / or a receiving hole. When the convex structures and the receiving holes provided on the two rollers rotate to between the two rollers, the convex structures face the concave regions, and the dimension of the convex structures in the radial direction of the rollers is greater than or equal to the preset distance, so as to push a part of the structure of the laminar board into the receiving holes. In the present utility model, the outer circumferential surfaces of the two rollers are provided with convex structures and receiving holes, there is a preset distance between the two rollers, and the dimension of the convex structures extending in the radial direction of the rollers is greater than or equal to the preset distance. When the laminar board passes through the preset distance, the convex structures can extrude the laminar board so that a part of the structure of the laminar board is pushed into the receiving holes, thereby forming closely arranged holes in the laminar board. By providing the holes, the air in the laminar board can more easily overflow during the hot pressing process, improving the flatness and interface connection performance of the laminar board.

[0039] According to an exemplary embodiment of the present disclosure, as Figures 1 to 3 shown, this embodiment provides a laminar board punching device 100. It should be noted that Figure 4 a laminar board 500 is shown. The laminar board 500 includes a skin layer 504, a honeycomb core 503, a film 501, a steel plate 502, a film 501, and a skin layer 504 stacked in sequence from bottom to top. The laminar board punching device 100 provided by the embodiments of the present disclosure is, for example, arranged upstream of the production line of the laminar board forming system, that is, the film 501 can be punched (i.e., pre-treated) before the film 501 adhesively connects the steel plate 502, the skin layer 504, and the honeycomb core 503.

[0040] As Figure 1 and Figure 3 shown, the laminar board punching device 100 includes two rollers 10 with a preset distance therebetween. The space between the two rollers 10 is for the laminar board 500 to pass through. In one example, the dimension of the preset distance is slightly smaller than the thickness of the film 501 of the laminar board 500, so as to drive the rotation of the rollers 10 through the rolling friction force between the laminar board and the rollers 10, so that the multiple convex structures 10a on the surface of the rollers 10 can punch the laminar board successively, improving the punching uniformity.

[0041] Wherein, the outer circumferential surface of each roller 10 provided by the embodiments of the present disclosure is provided with multiple convex structures 10a and / or multiple receiving holes 10b. The linear velocities of the two rollers 10 in rotation are the same. When the convex structures 10a and the receiving holes 10b provided on the two rollers 10 rotate to between the two rollers 10, the convex structures 10a face the receiving holes 10b. As Figure 1 and Figure 3As shown, the convex structure 10a and the roller 10 are an integral structure or can be a detachable structure. Refer to Figure 1 , the dimension of the convex structure 10a in the radial direction of the roller 10 is greater than or equal to a preset spacing to ensure that it can penetrate the adhesive film 501 of the laminate 500, thereby forming a through hole in the adhesive film 501.

[0042] As Figure 1 shown, the receiving hole 10b is formed by indenting inward from the radial direction of the roller 10. The receiving holes 10b can be evenly distributed along the circumferential direction of the roller 10 to form a group of receiving holes 10b, and multiple groups of receiving holes 10b are arranged along the axial direction of the roller 10 (i.e., the width direction of the laminate).

[0043] In one example, refer to Figure 1 , only multiple convex structures 10a are provided on the outer peripheral surface of one of the two rollers 10, and only multiple receiving holes 10b are provided on the outer peripheral surface of the other.

[0044] In another example, refer to Figure 2 , multiple convex structures 10a and multiple receiving holes 10b are provided on each roller 10. When the convex structures 10a and the receiving holes 10b on the two rollers 10 rotate to between the two rollers 10, the convex structures 10a are aligned with the concave structures, and the convex structures 10a squeeze the laminate to push a part of the structure of the laminate into the receiving holes 10b, thereby opening a through hole in the laminate.

[0045] In the embodiments of the present disclosure, the outer peripheral surfaces of the two rollers are provided with convex structures and receiving holes, there is a preset spacing between the two rollers, and the dimension of the convex structure extending in the radial direction of the roller is greater than or equal to the preset spacing. When the laminate passes through the preset spacing, the convex structure can squeeze the laminate so that a part of the structure of the laminate is pushed into the receiving hole, thereby forming closely arranged holes in the laminate. By setting the holes, the air in the laminate is more likely to overflow during the hot pressing process, improving the flatness and interface connection performance of the laminate.

[0046] In an exemplary embodiment, as Figure 1 shown, the embodiments of the present disclosure provide a laminate punching device 100. The laminate punching device 100 includes two rollers 10. There is a preset spacing between the two rollers 10. The outer peripheral surface of each roller 10 is provided with a convex structure 10a and / or a receiving hole 10b. When the convex structures 10a and the receiving holes 10b provided on the two rollers 10 rotate to between the two rollers 10, the convex structures 10a are aligned with the concave regions, and the dimension of the convex structures 10a in the radial direction of the roller 10 is greater than or equal to the preset spacing to push a part of the structure of the laminate into the receiving holes 10b.

[0047] AsFigure 1 As shown, two rollers are drivingly connected through gears (not shown in the attached drawings), and the two rollers rotate in opposite directions and have equal linear speeds.

[0048] In one example, referring to Figure 1 , the two rollers have the same radius, and the radii and number of teeth of the dimensions connected to the two rollers are also the same, so that the two rollers 10 rotate in opposite directions and have the same linear speed of rotation, ensuring that the multiple protruding structures 10a and the multiple accommodating holes 10b provided on the two rollers 10 are always aligned.

[0049] In some embodiments, as shown in Figure 1 and Figure 3 , the two rollers 10 include a first roller 11 and a second roller 12. The outer peripheral surface of the first roller 11 is provided with a plurality of protruding structures 10a extending radially outward, and the outer peripheral surface of the second roller 12 is provided with a plurality of accommodating holes 10b formed by recessing radially inward. That is, the protruding structures 10a are only provided on one of the rollers 10, and the accommodating holes 10b are only provided on the other roller 10, so that it is convenient to maintain the roller 10. For example, when a through hole is not formed at a certain position of the adhesive film, it can be directly detected on the first roller 11 to quickly find out the protruding structure 10a with problems.

[0050] Among them, the shape of the protruding structure 10a includes a conical shape, a cylindrical shape, a prismatic shape, a pyramidal shape, etc., which can be adaptively set according to requirements and are not overly limited.

[0051] Among them, as shown in Figure 1 , the first roller 11 includes a cylindrical first main body portion 111. The protruding structure 10a is provided on the outer peripheral surface of the first main body and is evenly distributed along the circumferential direction of the first main body portion 111. In this embodiment, by evenly distributing the multiple protruding mechanisms along the direction of the first main body portion 111, a plurality of through holes arranged at equal intervals can be formed by the protruding structure 10a in the extending direction of the laminated board. Referring to Figure 1 , the first main body portion 111 and the protruding structure 10a are detachably connected. The detachable connection methods include, for example, snap connection, fastener connection, etc. It can be understood that the protruding structure 10a is used to form through holes on the laminated board, and long-term operation is likely to cause wear and performance degradation. By setting the protruding structure 10a to be detachably connected, it is convenient to perform maintenance and replace the protruding structure 10a later.

[0052] Among them, as shown in Figure 1 , the second roller 12 includes a second main body portion 121 and a plurality of connecting portions 122. The second is in a cylindrical structure, and the plurality of connecting portions 122 are arranged inside the cylindrical structure and are connected to the inner wall of the cylindrical structure. The connecting portions 122 are used to connect to the rotating shaft of the second roller 12.

[0053] Among them, as Figure 1 shown, along the radial direction of the second main body portion 121, the accommodation hole 10b penetrates through the second main body portion 121 to communicate the outer wall surface and the inner wall surface of the cylindrical structure. It can be understood that when the laminate punching device 100 punches the laminate, the convex structure 10a pushes part of the laminate into the accommodation groove, and then enters the second main body portion 121 of the second pressing roller, facilitating the unified recovery of the waste generated by punching.

[0054] In some alternative embodiments, the connecting portion 122 may be a spoke, that is, a number of rods or bars extending outward from a center in the same plane. In another example, the connecting portion 122 may also be provided as a sector with a notch. It can be understood that when the laminate punching device 100 punches the laminate, waste generated by punching will be collected in the second main body portion 121. By setting the connecting portion 122 as a spoke or a sector with a notch, it is possible to take out the waste in the second main body portion 121 while ensuring the rotation of the second pressing roller.

[0055] Among them, as Figure 1 shown, the first rolling roller 11 is arranged above the second rolling roller 12. Since the convex structure 10a is provided on the first rolling roller 11 and the accommodation hole 10b is provided on the second rolling roller 12, after the laminate is pushed into the accommodation hole 10b by the convex structure 10a, it can fall into the second main body portion 121 of the second rolling roller 12 under the action of gravity, realizing the automatic collection of waste generated by punching the laminate.

[0056] In an exemplary embodiment, as Figures 1 to 3 shown, the present disclosure embodiment provides a laminate punching device 100. The laminate punching device 100 includes two rolling rollers 10. There is a preset distance between the two rolling rollers 10. The outer peripheral surface of each rolling roller 10 is provided with a convex structure 10a and / or an accommodation hole 10b. When the convex structure 10a and the accommodation hole 10b provided on the two rolling rollers 10 rotate to between the two rolling rollers 10, the convex structure 10a faces the concave region, and the dimension of the convex structure 10a in the radial direction of the rolling roller 10 is greater than or equal to the preset distance, so as to push part of the structure of the laminate into the accommodation hole 10b.

[0057] As Figure 2 shown, the outer peripheral surfaces of the two rolling rollers 10 are both provided with a convex structure 10a and an accommodation hole 10b. The convex structure 10a and the accommodation hole 10b located on the same side are arranged alternately along the axial direction of the rolling roller 10. In one example, the two rolling rollers 10 may be exactly the same. By staggering the two rolling rollers 10 in the axial direction of the rolling roller 10 by a preset distance, the convex structure 10a on one rolling roller 10 can be made to face the accommodation hole 10b on the other rolling roller 10.

[0058] As can be seen from the above, in the laminate punching device 100 provided in this embodiment, two exactly the same rollers 10 can be used for punching. The two rollers 10 can be manufactured by the same process. The two rollers 10 can punch from the bottom surface of the laminate 500 upwards and from the top surface downwards respectively. This punching method enables both sides of the laminate 500 to be stressed, avoiding abnormal deformation caused by only one-sided stress of the laminate 500.

[0059] According to an exemplary embodiment of the present disclosure, as Figure 3 shown, the present disclosure embodiment also provides a laminate forming system. The laminate forming system includes a laying device 200, a heating device 300, a cutting device 400, and the laminate punching device 100 provided in any of the foregoing embodiments of the present disclosure. The laminate punching device 100, the laying device 200, the heating device 300, and the cutting device 400 are arranged in sequence along the conveying direction of the laminate 500 ( Figure 3 the orientation is to the right as described).

[0060] The working principle of the laminate forming system provided in the present disclosure embodiment can be: First, the adhesive film 501 of the laminate 500 can be pretreated at the laminate punching device 100 to form an adhesive film 501 with closely arranged holes. Then, the adhesive film 501 is conveyed to the laying device 200 and laminated with materials (such as a steel plate 502, a honeycomb core 503, a skin layer 504, etc.). Then, the heating device 300 (such as a hot pressing device) hot presses the laminated multi-layer materials to tightly bond the multi-layer materials. Then, the cutting device 400 can cut and sever the laminate according to requirements. In this embodiment, by setting the laminate punching device 100 upstream of the production line, the adhesive film 501 can be pre-punched. The pores on the adhesive film 501 increase the transition time for the air in the laminate to be discharged during the hot pressing process, enabling the steel plate 502 to be tightly bonded to other materials, and improving the flatness and interface bonding property of the laminate.

[0061] Moreover, the waste generated by punching the adhesive film 501 can be recycled (stored in the second roller during the punching process) and reused, reducing the usage cost of the adhesive film 501.

[0062] In the description of the present disclosure, it should be understood that the orientation or positional relationship indicated by terms such as "upper", "lower", "parallel", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present disclosure and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present disclosure.

[0063] In addition, the terms "first", "second", and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first", "second", and "third" may explicitly or implicitly include at least one such feature.
