Description

Technical Field

[0002] With the advancement of technology, soft metal sheets have found wide applications in numerous fields such as electronic component manufacturing, aerospace, automotive manufacturing, and energy and chemical industries. Taking the new energy battery industry as an example, sodium / potassium / calcium / magnesium ion batteries require sodium / potassium / calcium / magnesium sheets in laboratory production. Currently, highly active metal sheets in laboratories are obtained through manual rolling of soft metal blocks in a vacuum, anhydrous, and oxygen-free environment, followed by complex stamping processes. This method is inefficient and hinders battery development progress. While specialized stamping machines or metal rolling mills exist, which can produce soft metal sheets of the target thickness, they are expensive, complex to operate, and involve cumbersome processes, resulting in high production costs.

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0022] It should be noted that any components or structures not described in detail below employ conventional techniques in this field. Those skilled in the art can combine and use them without any inventive effort.

[0023] like Figure 1 As shown: This utility model discloses a soft metal pressing and thinning system, including a first film unwinding mechanism 1, a soft metal unwinding mechanism 2, a second film unwinding mechanism 3, a first film tension correction mechanism I 4, a soft metal tension correction mechanism I 5, a second film tension correction mechanism I 6, a first film oiling mechanism 7, a second film oiling mechanism 8, a first oil film thickness detection mechanism 9, a second oil film thickness detection mechanism 10, a first pressure applying mechanism 11, a second pressure applying mechanism 12, a first pressing assembly, a second pressing assembly, a first film tension correction mechanism III 19, a second film tension correction mechanism III 21, a first film winding mechanism 22, a second film winding mechanism 23, a pressing gap adjustment mechanism 24, and a control device 20;

[0024] A pressing gap adjustment mechanism 24 is disposed between the first pressing assembly and the second pressing assembly to adjust the gap between the first pressing assembly and the second pressing assembly to obtain a soft metal sheet of a set thickness. The first oil film thickness detection mechanism 9 and the second oil film thickness detection mechanism 10 are respectively disposed at the workstations after the first film coating mechanism 7 and the second film coating mechanism 8. They are respectively used to detect the oil film thickness on the first film layer and the oil film thickness on the second film layer after coating. The first oil film thickness detection mechanism 9 and the second oil film thickness detection mechanism 10 are both connected to the control device 20 to transmit the oil film thickness detection results to the control device 20. The control device 20 is also provided with a first oil control mechanism 25 and a second oil control mechanism 26. The first oil control mechanism 25 is connected to the first film coating mechanism 7, and the second oil control mechanism 26 is connected to the second film coating mechanism 8. The control device 20 will adjust the coating amount of the corresponding coating mechanism through the oil control mechanism after considering the actual needs based on the oil film thickness fed back by the control device 20.

[0025] The first film unwinding mechanism 1 unwinds the first film layer and conveys it to the first film layer oiling mechanism 7 via the first film layer tension correction mechanism I4 for oiling. After oiling, it continues to be conveyed between the first pressing assembly and the second pressing assembly. The second film unwinding mechanism 3 unwinds the second film layer and conveys it to the second film layer oiling mechanism 8 via the second film layer tension correction mechanism I6 for oiling. After oiling, it continues to be conveyed between the first pressing assembly and the second pressing assembly. The soft metal layer is unwound and conveyed between the first pressing assembly and the second pressing assembly via the soft metal layer tension correction mechanism I5, with the soft metal layer located between the first film layer and the second film layer. The first pressure applying mechanism 11 and the second pressure applying mechanism 12 are respectively connected to the first pressing assembly and the first pressing assembly. The second pressing assembly is connected, the first pressing mechanism 11 applies pressure to the first pressing assembly, and the second pressing mechanism 12 applies pressure to the second pressing assembly, so that the first pressing assembly and the second pressing assembly respectively squeeze the soft metal layer from the two surfaces of the soft metal layer to achieve the pressing and thinning of the soft metal layer; after pressing, the first film layer and the second film layer are respectively conveyed to the first film layer winding mechanism 22 and the second film layer winding mechanism 23 via the first film layer tension correction mechanism III 19 and the second film layer tension correction mechanism III 21, respectively. The soft metal layer is attached to the first film layer or the second film layer, and it can be wound together with the first film layer to the first film layer winding mechanism 22, or it can be wound together with the second film layer to the second film layer winding mechanism 23.

[0026] Working principle: The oiling mechanism contains any one of mineral oil, dimethyl silicone oil, heat transfer oil, white oil, or blended oil. By applying oil to the first and second film layers and controlling the amount of oil applied through the oil control mechanism, on the one hand, the first and second film layers can have good lubrication, reducing the frictional resistance during soft metal pressing, making the pressing process smoother and improving pressing efficiency. On the other hand, the amount of oil applied will affect the adhesion between the film layer and the soft metal layer. By controlling the amount of oil applied, the adhesion between the first and second film layers and the soft metal layer is made different, so that one film layer can be removed after pressing, and the soft metal sheet can be relatively tightly attached to the other film layer for winding and use.

[0027] To make the entire system more compact, and to facilitate installation and use while reducing space occupancy, as a preferred technical solution, another embodiment of this utility model further includes a pressing frame, on which the first oil film thickness detection mechanism 9, the second oil film thickness detection mechanism 10, the first pressure mechanism 11, the second pressure mechanism 12, the first large pressure roller 13, the second large pressure roller 14, the first small pressure roller 15, and the second small pressure roller 16 are all mounted.

[0028] Specifically, both the first oil film thickness detection mechanism 9 and the second oil film thickness detection mechanism 10 are laser measuring instruments. The two laser measuring instruments emit infrared rays towards the first and second oiled film layers, respectively, and the corresponding oil film thickness is obtained by analyzing the reflected infrared rays. Using the first oil film thickness detection mechanism 9 and the second oil film thickness detection mechanism 10, the thickness of the oil film can be measured quickly without affecting production.

[0029] As a preferred technical solution, in another embodiment of this utility model, the first pressing mechanism 11 and the second pressing mechanism 12 are each composed of two hydraulic cylinders. That is, the two hydraulic cylinders act simultaneously to apply pressure to the first pressing component, and the other two hydraulic cylinders act simultaneously to apply pressure to the second pressing component, so that the two pressing components apply pressure to the soft metal layer from the two surfaces of the soft metal layer to achieve pressing and thinning.

[0030] In this embodiment, the hydraulic cylinder can precisely adjust the pressure applied to the first and second pressing components to meet the pressing process requirements. Simultaneously, to prevent impact and damage to the pressing components during pressure application, corresponding buffer and deceleration structures are also required.

[0031] Furthermore, the first pressing assembly includes a first large pressing roller 13 and a first small pressing roller 15, and the second pressing assembly includes a second large pressing roller 14 and a second small pressing roller 16. The first large pressing roller 13 and the second large pressing roller 14 rotate and respectively drive the first small pressing roller 15 and the second small pressing roller 16 to rotate relative to each other.

[0032] Larger pressure rollers, with their greater size and weight, also possess better rigidity and strength, allowing for better stability during the pressing process. Smaller pressure rollers, on the other hand, more easily achieve the desired reduction and deformation, thus enabling precise pressing and thinning of soft metals. The combination of large and small pressure rollers not only improves rolling efficiency and product quality but also reduces equipment load and energy consumption, making it widely applicable.

[0033] As a preferred technical solution, in another embodiment of the present invention, the first large pressure roller 13 and the second large pressure roller 14 are respectively connected to a servo motor through a reducer, and are controlled by the rotation of the servo motor to drive the first small pressure roller 15 and the second small pressure roller 16 to rotate relative to each other.

[0034] As a preferred technical solution, another embodiment of the present invention further includes a first film layer tension correction mechanism II17 and a second film layer tension correction mechanism II18 for tensioning and correcting the oiled first film layer and the oiled second film layer, respectively.

[0035] As a preferred technical solution, another embodiment of this utility model also includes a soft metal layer tension correction mechanism II 20 and a soft metal layer winding mechanism 23. After the soft metal sheet is pressed, it is transported to the soft metal layer winding mechanism 23 via the soft metal layer tension correction mechanism II 20 for winding, so that it can be collected and processed in other ways.

[0036] In all the above embodiments, the first and second film layers can be PET films with different release forces, or metal foils with different coefficients of friction with the soft metal layer. The use of PET film layers or metal foils serves two purposes: firstly, it protects the soft metal layer from damage throughout the lamination process; secondly, the difference in release force and coefficient of friction further promotes effective separation between the soft metal layer and the first or second film layer after lamination, improving lamination efficiency while ensuring the lamination effect, resulting in a smoother and more even surface of the soft metal layer.

[0037] In summary, this utility model achieves the purpose of soft metal lamination and thinning at a low cost through the scientific combination and ingenious arrangement of conventional structures. It can obtain soft metal sheets with a thickness of 4-100μm according to the needs, and is suitable for industrialization and large-scale promotion and application.

[0038] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make modifications, alterations, substitutions, and variations to the above embodiments within the scope of the present invention. Furthermore, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of the different embodiments or examples.
