Description

Technical Field

[0001] The present invention relates to the technical field of manufacturing wireless charging coils, and in particular to a wireless charging coil manufacturing device. Background Art

[0002] Wireless charging technology is mainly based on the principle of electromagnetic induction, that is, using an alternating magnetic field to transmit energy between a transmitting coil and a receiving coil. When an alternating current passes through the transmitting coil, it generates an alternating magnetic field. This magnetic field passes through the receiving coil and induces an alternating electromotive force in the receiving coil, thereby charging the device at the receiving end. Therefore, the coil is an important component in wireless charging devices. It is itself an inductor element, which uses the characteristics of inductance to store and transmit magnetic energy; the manufacturing process of the coil includes winding, tightening the coil, and pasting magnetic isolation sheets. The magnetic isolation sheet has the function of blocking or guiding the magnetic field through high magnetic permeability materials.

[0003] In the manufacturing process of traditional wireless charging coils, after the coil is wound, it needs to be tied with tape to improve the winding firmness and then a magnetic isolation sheet is attached. However, after some coils are wound, the elasticity of the wire itself will cause deformation after winding, and the coil is loose and not firm. The coil needs to be further tightened and shaped. When the coil is tightened, if the coil lacks a fixed shape, the wire is likely to scatter or separate during the tightening process, causing damage to the coil. Summary of the Invention

There are eight sliding lock plates movably connected above the coil fastening platform, and a lock plate slider is fixedly connected to the bottom of the sliding lock plate, and the lock plate slider is slidably connected to the plane guide groove. One end of the sliding lock plate facing the center of the coil fastening platform is fixedly connected to the limit pressure plate, and the limit pressure plate is parallel to the upper surface of the coil fastening platform. A lock plate push shaft is vertically welded below the lock plate slider, and the eight lock plate push shafts are respectively rotatably connected to the outer ends of the eight rotary disk connecting rods. The lower end of the coil center boss is fixedly connected to a boss pull plate, and the boss pull plate is located inside the coil fastening platform, and a boss tension spring is fixedly connected between the upper surface of the boss pull plate and the upper wall inside the coil fastening platform.

[0006] Furthermore, a capping glue dispensing machine is hinged on the upper left side of the coil fastening platform, and eight glue nozzles are fixedly connected to the lower surface of the capping glue dispensing machine. The eight glue nozzles are evenly distributed radially with the center of the capping glue dispensing machine as the center.

[0007] Furthermore, the upper surface of the capping type glue dispensing machine is fixedly connected with a diversion cavity, and the side surface of the diversion cavity is fixedly connected with eight glue diversion pipes.

[0008] Furthermore, the top of the diversion cavity is connected to the output end of the glue pump through a pipeline, and the glue outlet nozzle is connected to the diversion cavity through a glue diversion pipe.

[0009] Furthermore, when the capping glue dispensing machine covers the top of the coil fastening platform, the eight glue outlet nozzles and the eight sliding locking plates are staggered.

[0010] Furthermore, a pressure plate connecting rod is fixedly connected to the lower end of the magnetic isolation plate pressure frame, and the lower end of the pressure plate connecting rod is fixedly connected to the magnetic isolation plate pressure plate, and the pressure plate connecting rod is perpendicular to the magnetic isolation plate pressure plate.

[0011] Furthermore, the pressure plate connecting rod is coaxial with the magnetic isolation plate pressure plate, and eight strip-shaped pressure plate openings are longitudinally opened on the magnetic isolation plate pressure plate.

[0012] Furthermore, when the magnetic isolation plate pressure frame covers the top of the coil fastening platform, the eight pressure plate openings and the eight sliding lock plates are staggered, and a pre-stressed tension spring is fixedly connected to the top of the magnetic isolation plate pressure plate.

[0013] Furthermore, the prestressing plate is slidably connected to the pressure plate connecting rod, the prestressing plate is coaxial with the pressure plate connecting rod, and the prestressing plate is fixedly connected with eight prestressing push rods, which are radially distributed on the lower surface of the prestressing plate with the axis of the prestressing plate as the center, and the eight prestressing push rods are respectively slidably connected to the eight pressure plate through-holes.

[0014] Furthermore, the lower surface of the prestressing plate is fixedly connected to the upper end of the prestressing spring. Under normal circumstances, the prestressing plate is pulled close to the magnetic isolation plate by the prestressing spring, and the lower end of the prestressing push rod is located below the magnetic isolation plate.

[0015] The present invention provides a wireless charging coil manufacturing device, which has the following beneficial effects: The wireless charging coil manufacturing device in the present invention is used to repeatedly tension coils that are loose, loosely wound, and have elastically deformed wires. The device tightens and limits the coil so that the coil fits tightly against the surface of the coil tightening table, and the top of the coil is covered and fixed by a limiting pressure plate. In this state, when the wires at both ends of the coil are tightened at the same time, the coil will be further tightened, and due to the multi-directional limiting effect, the coil can be prevented from scattering and separating during the tightening process. The operation is convenient, and the eight limiting pressure plates can synchronously cover the top of the coil and separate from the top of the coil at the same time, so that the tightening and limiting of the coil are quick and stable. In addition, the gluing function of the coil is realized by the cooperation of the capping glue dispensing machine and the glue pump. When the coil is tensioned, in order to keep the coil structure stable, the capping glue dispensing machine can be used to apply liquid glue to the upper surface of the coil. The liquid glue is used to further fix the coil to prevent it from loosening or separating. The glue is applied to the gap between adjacent sliding lock plates on the upper surface of the coil through the glue nozzle to further stabilize the coil. At the same time, the coil is pressed and fixed by the limiting pressure plate to avoid the coil from loosening during the gluing process and to avoid covering the gluing position.

[0016] In addition, a pressing function of the magnetic isolation sheet is provided. After the gluing is completed, the magnetic isolation sheet is pasted and covered on top of the coil. The magnetic isolation sheet pressure frame is rotated to cover the magnetic isolation sheet, so that the pre-stressing push rod is fitted with the upper surface of the magnetic isolation sheet. The local area of the magnetic isolation sheet is pressed downward by the pre-stressing push rod, and the lower surface of the magnetic isolation sheet is fitted with the glued area above the coil. At this time, the sliding lock plate is controlled to move outward by the locking drive component, so that the limit pressure plate is withdrawn from above the coil, so that the magnetic isolation sheet is completely fitted with the coil. When the magnetic isolation sheet pressure frame is continuously pressed, the magnetic isolation sheet pressure plate will gradually move down and fit with the magnetic isolation sheet. At the same time, the center boss of the coil contracts downward under the downward pressure of the magnetic isolation sheet pressure frame, so that the magnetic isolation sheet and the coil are fully pressed, which can effectively improve the bonding firmness of the magnetic isolation sheet and the assembly precision of the coil.
