[0031] The technical solutions shown in this application will be described in detail below through specific embodiments. It should be noted that the description order of the following embodiments does not limit the priority order of the embodiments.

[0032] Please refer to Figure 1 、 Figure 2 and Figure 3The WPC wireless charging device of this embodiment includes a WPC circuit layer 1, a WPC carrier tape 2 and a WPC carrier 4.

[0033] During the specific implementation process, the WPC carrier tape 2 has a transfer working surface 2a, which is used to temporarily carry and protect the WPC circuit layer 1, that is, the transfer working surface 2a serves as a fixed protection area for the WPC circuit layer 1, and several WPC circuit layers 1 are arranged at intervals along a first direction and attached to the transfer working surface 2a, wherein the first direction is the extension direction of the two ends of the WPC carrier tape 2, so that the WPC carrier tape 2 can carry several WPC circuit layers 1.

[0034] Furthermore, the WPC carrier 4 is used to receive the WPC circuit layer 1 on the WPC carrier tape 2. The side of the WPC carrier 4 facing the WPC carrier tape 2 is provided with a bonding working surface 4a, which is used for transferring the WPC circuit layer 1 onto the bonding working surface 4a after the WPC carrier tape 2 is bonded to the WPC carrier 4, thereby ensuring a stable connection between the WPC carrier 4 and the WPC circuit layer 1.

[0035] That is, the main function of the WPC carrier 4 is to receive and fix the WPC circuit layer 1. The bonding working surface 4a of the WPC carrier 4 can ensure that the WPC carrier tape 2 is tightly bonded to it, so that the WPC circuit layer 1 can be accurately transferred from the WPC carrier tape 2 to the bonding working surface 4a, ensuring the position accuracy and stable physical connection of the WPC circuit layer 1 during the transfer process, thereby improving the reliability of the WPC wireless charging device.

[0036] Among them, a transfer identification part 3 is provided on the transfer working surface 2a, and the transfer identification part 3 includes a transfer identification wire frame 31. The transfer identification wire frame 31 is arranged at intervals along the first direction on the transfer working surface 2a, and the WPC circuit layer 1 is located in the transfer identification wire frame 31 in sequence. Based on the design of the transfer identification wire frame 31, a limit reference can be provided for the connection between the WPC circuit layer 1 and the WPC carrier tape 2. In an application scenario, the WPC circuit layer 1 can be automatically assembled to the transfer working surface 2a of the WPC carrier tape 2 by automated equipment on an automated production line, so that under the identification of the transfer identification wire frame 31, the assembly efficiency of the WPC circuit layer 1 and the WPC carrier tape 2 is guaranteed, and several WPC circuit layers 1 are facilitated to be efficiently transported and transferred under the protection of the WPC carrier tape 2, thereby improving the production efficiency of the WPC wireless charging device.

[0037] Furthermore, in the process of laminating the WPC carrier tape 2 to the WPC carrier 4 and transferring the WPC circuit layer 1 to the laminating working surface 4a, the transfer identification wireframe 31 can also facilitate the automatic laminating assembly between the WPC carrier tape 2 and the WPC carrier 4, that is, the WPC carrier tape 2 can be accurately output and laminarized on the WPC carrier 4 through the automated equipment on the automated production line, thereby realizing efficient and high-precision transfer of the WPC circuit layer 1 to the WPC carrier 4, thereby improving production efficiency.

[0038] It is understood that the transfer mark wire frame 31 can be formed on the transfer working surface 2a by laser etching, inkjet printing or screen printing.

[0039] In one embodiment, the WPC carrier tape 2 is designed in a roll-type structure, and the WPC carrier tape 2 includes a PET film or a PI film. Specifically, the WPC carrier tape 2 with a roll structure is convenient for continuous and stable feeding on the production line, and can realize continuous unwinding and transfer operations of the WPC carrier tape 2 for the WPC circuit layer 1, so that the WPC circuit layer 1 can be transferred to the WPC carrier 4 according to the set interval and position, thereby improving production efficiency. The roll-type design reduces the folding and bending of the WPC carrier tape 2 during transportation and storage, reduces the material loss rate, and improves production economy.

[0040] In addition, the PET film or PI film selected for the WPC carrier tape 2 has excellent mechanical strength, flexibility, heat resistance and chemical corrosion resistance, and can maintain stable physical properties under various environments. The light and thin characteristics of the PET film or PI film make the WPC carrier tape 2 more convenient for storage and transportation, and at the same time reduce the thickness accumulation of the material during the transfer process, which increases the overall volume of the WPC carrier tape 2 carrying the WPC circuit layer 1.

[0041] In one embodiment, the end of the WPC carrier tape 2 is integrally connected with a peeling operation part 21, which is used to peel the WPC carrier tape 2 from the WPC carrier 4 through the peeling operation part 21 after the WPC carrier tape 2 is attached to the WPC carrier 4, wherein the outer surface of the peeling operation part 21 is provided with anti-slip grooves, thereby simplifying the operation process and improving the convenience of production.

[0042] It is understandable that the peeling force between the WPC circuit layer 1 and the WPC carrier tape 2 cannot be too large to ensure that the WPC circuit layer 1 is not damaged during peeling. Therefore, the peeling force can be controlled by the peeling operation unit 21 to improve device reliability.

[0043] It can be understood that the WPC circuit layer 1 includes a WPC coil, which is responsible for receiving and transmitting energy during the electromagnetic induction process of wireless charging. That is, the WPC coil receives energy from the wireless charging base through electromagnetic induction technology and converts it into electrical energy that can be used by the mobile terminal device.

[0044] In the specific implementation process, refer to Figure 4 The WPC wireless charging device also includes a functional mainboard 5. The functional mainboard 5 is applied to a mobile terminal device. After the WPC carrier tape 2 is transferred, the WPC carrier 4 carries the WPC circuit layer 1 and is connected to the functional mainboard 5. A preset spatial distance is maintained with the functional mainboard 5, so that this preset spatial distance serves as a spatial buffer and ensures electrical isolation between the two.

[0045] Furthermore, the WPC circuit layer 2 has multiple feeding point areas 11, each feeding point area 11 is correspondingly provided with a mainboard connector 12, and the mainboard connector 12 is electrically connected to the functional mainboard 5 to optimize the energy transmission path, evenly distribute the transmission load, and improve the overall signal transmission efficiency. That is, the WPC circuit layer 2 is electrically connected to the functional mainboard 5 through the mainboard connector 12, thereby realizing the design function of wireless charging through the control of the functional mainboard 5.

[0046] The motherboard connector 12 includes a metal spring to ensure a stable, low-impedance electrical connection between the WPC circuit layer 2 and the functional motherboard 5 .

[0047] Continue to combine Figure 5 The transfer identification part 3 includes a color difference identification line 32, which is perpendicular to the first direction and is located between adjacent WPC circuit layers 1 on the transfer working surface 2a. Therefore, the color difference identification line 32 can be used as a connection limit reference between the WPC circuit layer 1 and the WPC carrier tape 2, and a fitting identification reference between the WPC carrier tape 2 and the WPC carrier 4. Therefore, under the identification of the color difference identification line 32, the assembly efficiency of the WPC circuit layer 1 and the WPC carrier tape 2, as well as the automatic fitting efficiency of the WPC carrier tape 2 and the WPC carrier 4 are guaranteed.

[0048] The color difference identification line 32 has a plurality of colors different from those of the WPC carrier tape 2 .

[0049] In one embodiment, the transfer identification member 3 may also include a two-dimensional identification code or a barcode, which is arranged at the top corner of the transfer working surface 2a. The two-dimensional identification code or barcode can store the product information of the WPC carrier tape 2 so that it can be scanned and read by automated equipment for traceability management.

[0050] In one embodiment, the transfer identification member 3 further includes an alignment identification hole 33 or an alignment identification recess 34, which is arranged at intervals along the first direction on the transfer working surface 2a and is located between adjacent WPC circuit layers 1. Thus, the alignment identification hole 33 or the alignment identification recess 34 can be used as a connection limit reference between the WPC circuit layer 1 and the WPC carrier tape 2, and a fitting identification reference between the WPC carrier tape 2 and the WPC carrier 4. Thus, under the identification of the alignment identification hole 33 or the alignment identification recess 34, the assembly efficiency of the WPC circuit layer 1 and the WPC carrier tape 2 and the automatic fitting efficiency of the WPC carrier tape 2 and the WPC carrier 4 are guaranteed.

[0051] Of course, in the specific implementation process, the color difference identification line 32 can also be used in conjunction with the alignment identification hole 33 or the alignment identification concave point 34. The alignment identification hole 33 or the alignment identification concave point 34 is located on one side of the color difference identification line 32 on the transfer working surface 2a or is configured on the color difference identification line 32 to achieve dual limiting and identification functions.

[0052] This embodiment also discloses a mobile terminal device, which includes the WPC wireless charging device described in any of the above embodiments. For other working principles and processes of the mobile terminal device of this embodiment, please refer to the description of the WPC wireless charging device in the above embodiment, which will not be repeated here.

This article uses specific examples to illustrate the principles and implementation methods of this application. It should be noted that in this application, the descriptions of each embodiment have different focuses. For parts that are not detailed or recorded in a certain embodiment, please refer to the relevant descriptions of other embodiments.

[0054] The above are only preferred embodiments of the present application and do not limit the patent scope of the present application.
