DETAILED DESCRIPTION
[0027] The present application is further described in detail below in conjunction with the accompanying drawings.
[0028] In this embodiment, refer to Figure 1-8 , a production process of mobile phone wireless charging adhesive paper auxiliary materials, including unwinding release film 8 and heat dissipation film 5, laminating release film 8 and heat dissipation film 5, die-cutting and removing waste retained in heat dissipation film 5, laminating double-sided adhesive tape 4, peeling release film 8 and attaching heat dissipation film 5 to first single-sided adhesive Mylar 6, laminating first single-sided adhesive Mylar 6 and protective film 7, die-cutting and removing waste from holes in protective film 7, trimming double-sided adhesive tape 4, shaping heat dissipation film 5 and first single-sided adhesive Mylar 6, and finally trimming to obtain finished products. Among them, the process includes laminating and die-cutting by laminating equipment and mold equipment, achieving an efficient automated production process, reducing the demand for labor and equipment coordination, and improving production efficiency and auxiliary material quality.
[0029] Reference Figure 2 , the steps of semi-finished product production are as follows: S1: unwinding the release film 8 and the heat dissipation film 5, cutting and segmenting the heat dissipation film 5 by an asynchronous knife, and attaching the cut and segmented heat dissipation film 5 to the release film 8; Specifically, first install the release film 8 and the heat dissipation film 5 on the unwinding device respectively to ensure a smooth unwinding process. Then, use an asynchronous knife to cut and segment the heat dissipation film 5. The function of the asynchronous knife is to cut the heat dissipation film 5 into a specific length and shape as needed. After the cutting is completed, the heat dissipation film 5 after cutting and segmenting is accurately attached to the release film 8. This process needs to ensure the accuracy and firmness of the attachment to avoid bubbles or offsets. Appropriate pressure and bonding equipment can be used to complete this operation to ensure that the heat dissipation film 5 is tightly bonded to the release film 8.
[0030] When performing step S1, i.e. unwinding the release film 8 and the heat dissipation film 5, and cutting and segmenting the heat dissipation film 5 by the asynchronous knife, it is judged whether the white heat dissipation film 5 can be normally asynchronous. If it is judged that the white heat dissipation film 5 cannot be normally asynchronous, then when the heat dissipation film 5 after cutting and segmenting is attached to the release film 8, 5U transparent double-sided tape is added. When the white heat dissipation film 5 cannot be normally asynchronous, it may cause the heat dissipation film 5 and the release film 8 to be loosely attached, affecting the subsequent production process and product quality. Adding 5U transparent double-sided tape can enhance the adhesion between the heat dissipation film 5 and the release film 8, ensuring that they can be tightly combined, thereby ensuring the smooth production and the quality stability of the product. The specific operation of adding 5U transparent double-sided tape is to accurately stick the transparent double-sided tape to the contact part of the heat dissipation film 5 and the release film 8 to ensure that the double-sided tape can fully bond the two.
[0031] Whether the white heat dissipation film 5 is normally asynchronous can be determined in the following ways: observe the cutting and segmenting process of the heat dissipation film 5 by the asynchronous knife to see whether the heat dissipation film 5 can be cut according to the preset rhythm and position, whether the segments after cutting are neat, and whether the length meets the requirements. Check whether the heat dissipation film 5 can be smoothly attached to the release film 8, and whether there is any jamming, offset or loose attachment. Sensors or detection equipment can be used to monitor the asynchronous state of the heat dissipation film 5. For example, the position and moving speed of the heat dissipation film 5 can be detected by a photoelectric sensor, and compared with the preset parameters to determine whether it is normally asynchronous. Sampling inspection is carried out on the products after bonding to check the bonding of the heat dissipation film 5 and the release film 8, and whether there are problems such as stratification and bubbles, so as to indirectly determine whether the asynchrony is normal. Through the comprehensive judgment of the above multiple methods, it can be more accurately determined whether the white heat dissipation film 5 can be normally asynchronous.
[0032] S2: performing a pressing process on the release film 8 and the heat dissipation film 5; Specifically, the laminated release film 8 and the heat dissipation film 5 are fed into a laminating device. The laminating device usually applies a certain pressure and temperature to make the release film 8 and the heat dissipation film 5 more tightly combined. During the laminating process, it is necessary to ensure that the pressure is evenly distributed to avoid the situation where local lamination is not firm. At the same time, temperature control is also very important. Too high or too low temperature may affect the laminating effect. The laminating time also needs to be adjusted according to the specific situation to ensure that the release film 8 and the heat dissipation film 5 are fully bonded. After the laminating process, the release film 8 and the heat dissipation film 5 will form a relatively stable whole, providing a good foundation for subsequent processing steps.
[0033] S3: die-cutting the heat dissipation film 5 on the release film 8 to obtain a formed heat dissipation film 5, and removing the waste remaining on the heat dissipation film 5; Specifically, a die-cutting device is used to die-cut the heat dissipation film 5 on the release film 8. The die-cutting device will accurately cut the heat dissipation film 5 according to the preset shape and size. During the die-cutting process, it is necessary to ensure the accuracy and stability of the mold to ensure that the molded heat dissipation film 5 meets the requirements. After the die-cutting is completed, the molded heat dissipation film 5 is obtained, and residual waste will be generated. At this time, it is necessary to use corresponding removal devices to clean up these wastes in time to avoid interference with subsequent production processes. The way to remove the waste can be to suck away the waste through an air suction device, or to grab the waste through a robotic arm and place it in a designated collection area. In the process of removing waste, the accuracy and efficiency of the operation must be ensured to improve production efficiency.
[0034] S4: unwinding the double-sided adhesive tape 4, and attaching the double-sided adhesive tape 4 to the formed heat dissipation film 5; Specifically, first install the double-sided adhesive tape 4 on the unwinding device to ensure that the unwinding process is smooth. Then, place the molded heat dissipation film 5 in a suitable position so that its surface is ready to receive the double-sided adhesive tape 4. Next, slowly unwind the double-sided adhesive tape 4 so that it gradually fits on the molded heat dissipation film 5. During the laminating process, attention should be paid to the alignment position to ensure that the double-sided adhesive tape 4 can evenly cover the surface of the heat dissipation film 5 and no bubbles or wrinkles are generated. A pressure roller or other compacting tool can be used to gently compact the double-sided adhesive tape 4 after it is laminated to enhance the adhesion between the tape and the heat dissipation film 5. At the same time, attention should be paid to controlling the laminating speed and pressure to ensure the stability and consistency of the laminating quality. After the laminating is completed, check the laminating condition of the double-sided adhesive tape 4 and the heat dissipation film 5 to ensure that the laminating is firm and defect-free.
[0035] S5: unwinding the first single-sided adhesive Mylar 6, peeling off the release film 8, and attaching the molded heat dissipation film 5 to the first single-sided adhesive Mylar 6; Specifically, the first single-sided adhesive Mylar 6 is installed on the unwinding device to ensure that the unwinding process is smooth and the Mylar is unfolded flat. Carefully peel off the release film 8. Appropriate tools or equipment can be used to gently peel off the release film 8 from the heat dissipation film 5, taking care to avoid damaging the heat dissipation film 5. Accurately attach the peeled molded heat dissipation film 5 to the first single-sided adhesive Mylar 6. During the attachment process, ensure the alignment accuracy of the heat dissipation film 5 and the Mylar to avoid offset or skew. Tools such as a pressing device or a roller can be used to gently press the attached heat dissipation film 5 and the Mylar to enhance the adhesion between them and ensure a firm attachment. Throughout the process, attention should be paid to the gentleness of the operation to avoid stretching, deformation or damage to the material. After the attachment is completed, check the attachment quality to ensure that the heat dissipation film 5 is tightly attached to the first single-sided adhesive Mylar 6 without bubbles, wrinkles or falling off.
[0036] S6: unwinding the protective film 7 at the same time, attaching the first single-sided adhesive Mylar 6 on the protective film 7, and laminating the first single-sided adhesive Mylar 6 and the protective film 7; Specifically, start the unwinding device at the same time to unwind the protective film 7, ensuring that the unwinding process of the protective film 7 is smooth and without wrinkles or distortion. Carefully attach the first single-sided adhesive Mylar 6 to the protective film 7, pay attention to the alignment position, and ensure that the Mylar and the protective film 7 are completely in contact. Use a laminating device to laminarize the first single-sided adhesive Mylar 6 and the protective film 7. The laminating equipment usually applies a certain pressure and temperature to enhance the adhesion between the Mylar and the protective film 7. During the laminating process, ensure that the pressure is evenly distributed to avoid local loose lamination. At the same time, control the temperature to prevent excessive temperature from damaging the material. The laminating time should be reasonably set according to the characteristics and requirements of the material to ensure that the laminating effect is optimal. After the lamination is completed, carefully check the fit of the Mylar and the protective film 7 to ensure that there are no bubbles, delamination or falling off. If problems are found, the equipment parameters should be adjusted in time or appropriate measures should be taken to repair them to ensure product quality.
[0037] S7: Die-cut the protective film 7 and remove the cut hole waste; Specifically, the protective film 7 attached with the first single-sided adhesive Mylar 6 is fed into the die-cutting equipment. The die-cutting equipment accurately die-cuts the protective film 7 according to the preset shape and size. During the die-cutting process, the accuracy and stability of the mold are ensured to ensure that the die-cut shape meets the requirements. After the die-cutting is completed, the cut hole waste will adhere to the protective film 7. Use a suction device or other waste removal equipment to remove the cut hole waste in time. The suction device sucks away the waste by generating suction and collects it into a designated container. In the process of removing waste, it is necessary to ensure the accuracy and efficiency of the operation to avoid waste residue affecting product quality. After the waste removal is completed, the die-cut protective film 7 is inspected to ensure that the hole shape is regular, the edges are smooth, and there is no residual waste.
[0038] S8: trimming the double-sided adhesive tape 4, the molded heat dissipation film 5 and the first single-sided adhesive Mylar 6 to obtain a semi-finished product; Specifically, the composite material bonded with the double-sided adhesive tape 4, the molded heat dissipation film 5 and the first single-sided adhesive Mylar 6 is placed on the trimming equipment. Start the trimming equipment and use a cutter or other trimming tools to trim the edges of the composite material. When trimming, ensure the sharpness and stability of the cutter to ensure the accuracy and quality of the trimming. Carefully trim the edges of the composite material, remove the excess parts, and make the edges neat and smooth. At the same time, pay attention to controlling the depth and width of the trimming to avoid damage to the internal structure of the material. During the trimming process, constantly check the trimming effect to ensure that it meets the requirements. After the trimming is completed, a semi-finished product is obtained and inspected to ensure that the edges are neat, burr-free, and defect-free.
[0039] Reference Figure 4 , the steps of producing the support member 13 are as follows: S8.1: unwinding the second single-sided adhesive Mylar tape 2, and attaching the adhesive side of the second single-sided adhesive Mylar tape 2 to the second adhesive region 10 on the double-sided adhesive tape 4; Specifically, install the second single-sided adhesive Mylar 2 on the unwinding equipment to ensure that the unwinding process is smooth and the Mylar is unfolded flat and wrinkle-free. Slowly unwind the second single-sided adhesive Mylar 2 so that it gradually approaches the double-sided adhesive tape 4. Align the adhesive side of the second single-sided adhesive Mylar 2 with the second pasting area 10 on the double-sided adhesive tape 4. Gently press the second single-sided adhesive Mylar 2 so that the adhesive side is firmly attached to the second pasting area 10 on the double-sided adhesive tape 4, ensuring that the pasting is tight without bubbles or gaps. During the pasting process, pay attention to controlling the pasting speed and pressure to ensure the pasting quality. After the pasting is completed, check the pasting effect to ensure that the pasting position of the second single-sided adhesive Mylar 2 and the double-sided adhesive tape 4 is accurate and firmly adhered.
[0040] S8.2: After the second single-sided adhesive Mylar 2 is pasted, the second single-sided adhesive Mylar 2 is punched and formed, and the second single-sided adhesive Mylar 2 and the double-sided adhesive tape 4, the heat dissipation film 5 and the first single-sided adhesive Mylar 6 are pasted together to form a support member 13.
[0041] Specifically, after the second single-sided adhesive Mylar 2 is pasted, the combined materials (including the second single-sided adhesive Mylar 2, the double-sided adhesive tape 4, the heat dissipation film 5 and the first single-sided adhesive Mylar 6) are moved to the working area of the punching equipment. The punching equipment punches and forms the second single-sided adhesive Mylar 2 according to the preset shape and size. During the punching process, the accuracy and stability of the punching die are ensured to ensure that the punched shape meets the requirements. During punching, the punching die is quickly pressed down to cut the second single-sided adhesive Mylar 2 into the required shape. After the punching is completed, the second single-sided adhesive Mylar 2 and the double-sided adhesive tape 4, the heat dissipation film 5 and the first single-sided adhesive Mylar 6 are pasted together to form the support 13. Check the punching effect of the support 13 to ensure that the edges are neat and burr-free, and the shape meets the design requirements. Perform quality inspection on the support 13 to check the adhesion firmness and matching accuracy of each component.

The position and size of the first pasting area 9 are determined according to the shape and size of the cable assembly to ensure that the cable assembly can be accurately pasted on the area. In actual operation, when the cable assembly needs to be pasted, align the back of the cable assembly with the first pasting area 9, and then press gently to firmly paste the cable assembly on the double-sided adhesive tape 4. During the pasting process, care should be taken to avoid skewness or misalignment of the cable assembly to ensure that subsequent assembly work can proceed smoothly. In addition, in order to ensure the firmness of the pasting, appropriate pressure or heating can be used to enhance the viscosity of the double-sided adhesive. At the same time, after the pasting is completed, the pasting of the cable assembly needs to be checked to ensure that it is firmly pasted and there are no bubbles or looseness.

[0053] Reference Figure 5-8In this embodiment, a mobile phone wireless charging adhesive paper auxiliary material is made by using the above-mentioned mobile phone wireless charging adhesive paper auxiliary material production process, and has the following characteristics: The mobile phone wireless charging adhesive paper auxiliary material is mainly composed of a variety of materials. Among them, the thickness of the black Mylar 1 is 0.205mm±0.02mm, which can provide certain shading and protection. The thickness of the second single-sided adhesive Mylar 2 is 0.12mm±0.012mm, which plays a role of connection and fixation. The thickness of the single-sided adhesive foam 3 is 0.1mm±0.001mm, which has the functions of buffering and protection. The thickness of the heat dissipation film 5 is 0.085mm±0.008mm, which helps to dissipate the heat generated during the wireless charging process of the mobile phone. The thickness of the first single-sided adhesive Mylar 6 is 0.015mm±0.0015mm, which also plays a role in structural connection. In addition, there is a protective film 7 made of blue silicone material to provide protection for the entire auxiliary material. In the design of the mobile phone wireless charging adhesive paper auxiliary material, a third adhesive area 11 and a fourth adhesive area 12 are provided on the single-sided adhesive foam 3. The third pasting area 11 is used to paste the cable assembly, and the cable assembly can also be pasted on the first pasting area 9 to ensure the stable connection of the cable assembly. The fourth area is used to stick the electromagnetic patch, and the electromagnetic patch can be electrically connected to the cable assembly to achieve specific functional requirements.
[0054] Specifically, the release film 8 includes polyester material and polyethylene material. The polyester material has good heat resistance and tensile strength, and the polyethylene material has low cost and high softness. For example, the polyester material can be a 100-micron thick polyester release film 8 or the polyethylene material can be a 80-micron thick polyethylene release film 8.
[0055] Black Mylar 1 includes PET material and PE material. PET material has high blackness and strong temperature resistance, while PE material has a lighter blackness but low cost. For example, PET material with a thickness of 205 microns ± 2 microns or PE material with a thickness of 180 microns ± 2 microns is selected. Use trimming tools to trim the edges to ensure smooth and neat edges.
[0056] The second single-sided adhesive Mylar 2 mainly includes acrylic material and silicone rubber material. For example, the thickness of the second single-sided adhesive Mylar 2 made of acrylic material can be 0.12mm±0.012mm; the second single-sided adhesive Mylar 2 made of silicone rubber can also use this thickness specification. During the bonding process, it is necessary to ensure that the adhesive side of the second single-sided adhesive Mylar 2 is firmly attached to the second bonding area 10 of the double-sided adhesive tape 4. After the bonding is completed, it is punched and formed so that the second single-sided adhesive Mylar 2 cooperates with the double-sided adhesive tape 4, the heat dissipation film 5 and the first single-sided adhesive Mylar 6 to form a stable support member 13, providing reliable structural support for the product.
[0057] The single-sided adhesive foam 3 is composed of polyurethane foam and polyethylene foam material. Polyurethane foam has excellent impact resistance. For example, a polyurethane foam material with a thickness of 0.1mm±0.001mm can be selected. Polyethylene foam material has the advantage of lower cost. For example, a polyethylene foam material with the same thickness of 0.1mm±0.001mm can be selected. In practical applications, a suitable foam material can be selected according to specific performance requirements and cost considerations. During the bonding process, it is necessary to strictly ensure that the adhesive surface of the single-sided adhesive foam 3 is set in a direction away from the protective film 7. The single-sided adhesive foam 3 is stably attached to the protective film 7 so that it is arranged side by side with the formed heat dissipation film 5 to ensure that the positional relationship between the two is accurate, laying a good foundation for subsequent processing steps.
[0058] The heat dissipation film 5 is white and has specific materials and specifications. The thickness of the heat dissipation film 5 is 0.085mm±0.008mm. The heat dissipation film 5 is usually composed of heat dissipation fillers and polymer matrix materials. Common heat dissipation fillers include aluminum oxide, boron nitride, graphite, etc. These fillers have high thermal conductivity and can effectively conduct heat away from the heat source. The particle size of the filler is usually between a few microns and tens of microns. Different particle sizes will affect the thermal conductivity and processing performance of the heat dissipation film 5. Polymer matrix materials such as polyimide (PI), polyester (PET), etc. have good flexibility, insulation and mechanical strength. Polyimide has high heat resistance and chemical corrosion resistance and can be used for a long time in high temperature environment. Polyester materials also have good performance. The width and length of the heat dissipation film 5 depend on the specific application requirements and can generally be customized.
[0059] The first single-sided adhesive Mylar 6 includes acrylic material and silicone rubber material. The acrylic material has good adhesion and temperature resistance, and the silicone rubber material has a wide temperature resistance range and high softness. For example, the acrylic material is selected to have a thickness of 0.015 mm ± 0.0015 mm. Carefully peel off the release film 8 to ensure that the formed heat dissipation film 5 is accurately attached to the first single-sided adhesive Mylar 6.
[0060] The double-sided adhesive tape 4 includes PE tape and PET tape. The PE tape has good viscosity and strong temperature resistance, and the PET tape has good durability. For example, the PE tape can be 100 micron thick, and the PET tape can be 80 micron thick. The positions need to be aligned when laminating.
[0061] The protective film 7 is usually made of blue silicone material, for example, a 120 micron thick blue silicone material protective film 7 is selected. The laminating device performs laminating processing on the first single-sided adhesive Mylar 6 and the protective film 7 to ensure a firm laminating effect.
[0062] In this embodiment, the laminating device performs lamination processing on the black Mylar 1, the second single-sided adhesive Mylar 2 and the single-sided adhesive foam 3, and applies appropriate pressure and temperature, for example, the laminating pressure is 150 kg ± 10 kg, and the temperature is 120°C ± 5°C. The trimming device performs trimming processing on the single-sided adhesive foam 3 to ensure that the size and shape of the finished product meet the requirements. For example, the accuracy of the trimming cut is controlled within the range of ± 0.1 mm, and it is ensured that the waste is completely excluded. The die-cutting device performs die-cutting processing on the finished product, excludes local waste, and ensures that the size of the finished product is accurate. For example, the die-cutting accuracy is ± 0.05 mm. When the finished product is attached to the shipping material belt, the flatness and stable attachment are ensured to facilitate subsequent transportation and storage.
[0063] The implementation principle of this embodiment is as follows: through an integrated production process, the problem of needing to process separately and then assemble in the traditional process is effectively avoided, manual intervention and equipment coordination requirements are reduced, and production efficiency is improved. Through precise trimming and pressing processes, a firm fit between the layers of materials is ensured, and the reliability and consistency of the auxiliary materials are improved. The use of different types of materials makes the performance of the auxiliary materials more stable in different environments, improving the quality and reliability of the overall product. By optimizing material selection and process parameter settings, production efficiency and auxiliary material quality are further improved, while costs are reduced, ensuring the performance stability and reliability of the auxiliary materials in different environments.
