[0002] In the field of electromagnetic shielding material manufacturing, with the increasing miniaturization, integration and high frequency of electronic equipment, the performance requirements for shielding materials are becoming higher and higher. Foam materials have been widely used in the field of electromagnetic shielding due to their light weight, softness and easy processing. However, in the process of preparing foam electromagnetic shielding materials, how to ensure the flatness, conductivity and stability of the material and the stability of the final product has always been a problem to be solved in the industry.

[0003] The traditional production process of semi-finished foam electromagnetic shielding materials usually includes the steps of core forming, conductive layer coating and adhesive treatment. However, in the existing preparation process, due to improper control of material transmission speed, the following technical problems often occur:

[0004] In the process of stacking multiple layers of materials, if the transmission speeds of each layer of material are not matched or unstable, the material will be stretched or compressed during transmission, resulting in bending deformation; this bending deformation not only affects the appearance quality of the product, but may also reduce its electromagnetic shielding effectiveness.

[0005] The instability of material transmission speed will also affect the fitting accuracy between the layers of materials; if defects such as position offset, bubbles or wrinkles occur during the bonding process, it will directly affect the conductive properties and electromagnetic shielding effectiveness of the shielding material.

[0006] In order to avoid the problems of bending and deformation of each layer of material and reduced fitting accuracy of each layer of material, production personnel often need to spend more time and energy on manual adjustments or rework, thereby reducing overall production efficiency.

[0026] 2) Automatically control the transmission speed of each layer of the semi-finished foam electromagnetic shielding material to match the speed of the controller, which is used to receive the speed signals sent by the first photoelectric sensor, the second photoelectric sensor and the third photoelectric sensor and control the rotation speed of the liner core conveying assembly, the semi-finished product conveying assembly and the shielding material semi-finished product conveying assembly to achieve a transmission speed of the liner core conveying assembly to convey the liner core to the second molding machine and / or a transmission speed of the shielding material semi-finished product conveying assembly to convey the shielding material semi-finished product to the output end of the third molding machine that is greater than the transmission speed of the semi-finished product conveying assembly to convey the semi-finished product to the third molding machine. On the one hand, the problem of stretching and bending of the material during the transmission process is avoided. On the other hand, the stability and safety of the material during the transmission process are ensured by reducing waiting time and accumulation, maintaining stable material tension, improving the smoothness of the production process and reducing human intervention, effectively avoiding bending and deformation of each layer of material, ensuring the conductive performance and electromagnetic shielding effectiveness of the shielding material, reducing production costs and improving production efficiency.

[0027] At the same time, by precisely controlling the transmission speed of each layer of material, it can be ensured that they can be accurately aligned when they reach the next molding machine or cutter assembly, thereby ensuring the subsequent fitting accuracy and effectively avoiding the occurrence of problems such as the decrease in the fitting accuracy of each layer of material. The conductive properties and electromagnetic shielding effectiveness of the shielding material are ensured, reducing production costs and improving production efficiency.

[0028] 3) It solves the technical problem that a product that requires multiple wrapping steps cannot be formed in one go on a continuous machine. This not only realizes the one-time forming of the wrapped product on a continuous machine, but also solves the complex problem of debugging required for each wrapping process, thereby improving production efficiency and stability.

[0029] 4) Molding components perform hot pressing and cold pressing on each layer of material in sequence. Hot pressing is usually used to soften the material and achieve the desired shape, while subsequent cold pressing helps consolidate the shape and increase the stability and durability of the material. This dual processing process helps ensure that each layer of material has good structural strength and shape retention.

[0031] 6) After receiving the speed signal from the fourth photoelectric sensor, the controller will immediately compare it with the liner core conveying speed. Through the built-in algorithm and logical judgment, the controller can automatically adjust the speed of the conductive foam conveying motor to keep the conveying speed of the conductive foam highly consistent with the conveying speed of the liner core. On the basis of speed matching, it ensures that the conductive foam can be tightly and evenly coated on the outside of the liner core to achieve a high-quality coating effect;

[0032] 7) After receiving the position signal from the fifth photoelectric sensor, the controller will perform fast and accurate signal processing and analysis; according to the preset algorithm and logic, the controller can determine whether the semi-finished product is in the correct pasting position and whether the working state of the adhesive conveying motor needs to be adjusted. Through the coordinated work of the fifth photoelectric sensor and the controller, it is ensured that the adhesive can be accurately pasted at the specified position, which helps to improve the pasting quality and consistency of the product. Accurate pasting control also helps to reduce the waste of adhesive materials and unnecessary cost expenditures;

[0033] 8) The sensor for the number of rotations of the conveying motor can detect the rotation of the conveying motor in real time and transmit the signal of the number of rotations to the controller. Since the length of the semi-finished shielding material driven by each rotation has been calculated and set in advance, the controller can accurately calculate the total length of the semi-finished shielding material according to the number of rotations; when the length of the semi-finished shielding material conveyed reaches the preset value, the controller will send an instruction to the cutter drive assembly to drive the cutter to perform cutting action, thereby ensuring that the length of the cut semi-finished shielding material accurately reaches the required length of the semi-finished shielding material, which not only improves production efficiency and product quality, but also reduces production costs.
