[0002] With the continuous development and progress of science and technology, wireless charger products have gradually entered the society, especially the mobile phone end application is relatively wide. Wireless chargers can eliminate the direct wiring connection between the charger and smart products such as mobile phones. It only needs to bring the wireless charger into close contact with the mobile phone to achieve fast charging, which is more convenient to use and has higher charging efficiency.

[0003] Wireless magnetizing components are widely used in magnetic wireless charging devices. Mobile phone wireless charging mostly uses adsorption to fix the phone on the wireless charging device. In order to be able to adsorb it, it is usually necessary to glue the wireless magnetizing components on the mobile phone. At present, the structure of some wireless magnetizing components is a circle of magnets glued on a metal part. The magnet is first placed in the fixture, and then glue is applied to the top surface of the magnet. After gluing, the metal part is placed and the surface of the metal part is pressurized. For the overall bipolar charging magnetic component, the normal assembly process is to assemble first and then magnetize the whole component (if a single magnet is magnetized first, it will cause the non-magnetic area of ​​the assembled component to be offset). Since the magnet is non-magnetic during assembly, the whole circle of metal parts is large and thin, and it is easy to deform. The magnet itself has tolerance or there is residual glue in the fixture groove, which causes the magnet to be low and uneven. There will be a gap between the magnet and the metal part, resulting in the assembled wireless magnetizing component to have undesirable phenomena such as debonding, size deviation, and deformation.

[0004] Therefore, the applicant intends to propose a pressure maintaining device for a wireless magnetizing component to solve the above-mentioned problem. Utility Model Content

[0023] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] The utility model provides a pressure-maintaining device for a wireless magnetizing component. The wireless magnetizing component 6 includes a plurality of magnets 61 and a metal piece 62. Figure 1 As shown, the pressure-holding device includes a pressure-holding platform 1 and a pressure-holding tool 2. The pressure-holding platform 1 is used to place the wireless magnetizing component 6 to be pressurized. The pressure-holding tool 2 uniformly applies pressure to the wireless magnetizing component 6 placed on the pressure-holding platform 1, so that the magnet 61 and the metal part 62 fit together without a gap, thereby avoiding the wireless magnetizing component 6 from having unqualified phenomena such as debonding, dimensional deviation, deformation, etc.

[0025] The pressure-maintaining platform 1 is recessed with a limiting groove 11 for placing the metal part 62, and the magnet 61 is placed on the top surface of the metal part 62 after the glue is applied 63. The limiting groove 11 constrains the positions of the metal part 62 and the magnet 61 to avoid displacement of the metal part 62 and the magnet 61 during subsequent pressure maintenance, resulting in unqualified phenomena such as dimensional out-of-tolerance and deformation. At the same time, the magnet 61 is placed on the top surface of the metal part 62 after the glue is applied 63 to avoid deformation of the wireless magnetization component 6. Because the metal part 62 is mostly a large thin sheet and the magnet 61 has a tolerance, if the metal part 62 is placed on the top of the magnet 61, the pressure-maintaining tooling 2 applies pressure to the wireless magnetization component 6. Due to the unevenness of the magnet 61, the metal part 62 cannot be evenly stressed and thus deformed.

[0026] The top of the pressure-maintaining platform 1 is provided with a pressure-maintaining tool 2, with particular reference to Figure 4The pressure-maintaining fixture 2 includes a driving member 21, a base 22, a spring 23 and a pressing head 24. The driving member 21 is fixedly connected to the base 22, and the base 22 is connected to the pressing head 24 through the spring 23. The driving member 21 drives the pressing head 24 to move in a direction perpendicular to the pressure-maintaining platform 1, so that the pressing head 24 maintains pressure on the magnet 61 of the pressure-maintaining platform 1. The spring 23 between the base 22 and the pressing head 24 is used to buffer the pressure applied by the driving member 21 to prevent the pressing head 24 from instantly crushing the wireless magnetizing component 6 when the pressing head 24 maintains pressure on the magnet 61. The pressure-maintaining device includes a plurality of pressing heads 24 corresponding to the plurality of magnets 61, each of the pressing heads 24 maintains pressure on each corresponding magnet 61, and the magnets 61 have tolerances. When the pressure-maintaining fixture 2 applies pressure to the wireless magnetizing component 6, each pressing head 24 squeezes the corresponding magnet 61, and the spring 23 between the pressing head 24 and the base 22 is used for buffering, so that the magnet 61 with tolerance can be fully fitted with the metal part 62 without damaging the metal part 62.

[0027] Key References Figure 1 , also includes a swinging material platform 3, the swinging material platform 3 and the pressure holding platform 1 are arranged on the same plane, the swinging material platform 3 is provided with a groove 31, the groove 31 is used to place the magnet 61, the magnet 61 that meets the size requirements is first soaked in an accelerator so that the glue 63 can be quickly solidified during bonding, and then the magnet 61 is placed in the groove 31 of the swinging material platform 3 using a vibration plate or manually; also includes a transfer device 4, the transfer device 4 is arranged on the top of the swinging material platform 3 and the pressure holding platform 1, the transfer device 4 is movably connected to the pressure holding tooling 2, and the transfer device 4 drives the pressure holding tooling 2 to absorb the swinging material platform 3. The magnet 61 on the material platform 3 is moved to the pressure holding platform 1 and placed on the metal part 62 after the glue 63 is dispensed (glue anaerobic glue). The magnet 61 and the metal part 62 are both placed in the limiting groove 11 of the pressure holding platform 1. Then the driving part 21 of the pressure holding tooling 2 drives the pressure head 24 to move in a direction perpendicular to the pressure holding platform 1, and then the pressure head 24 keeps the magnet 61 on the pressure holding platform 1 for a period of time. The glue 63 is cured, and the magnet 61 is completely fitted with the metal part 62. A lifting device 5 is provided at the bottom of the pressure holding platform 1. Finally, the lifting device 5 lifts the assembled wireless magnetizing component 6 to demould.

[0028] The magnet 61 is in the shape of a fan ring, and the metal member 62 is in the shape of a circular ring. Figure 5 As shown, the wireless magnetizing component 6 on the magnetic wireless charging device is usually arranged in a circle. The circular design helps to realize the wireless charging function and is beautiful, so the metal part 62 is preferably in a circular ring shape, and the plurality of magnets 61 are preferably in a fan ring shape to cooperate with the metal part 62.
