[0002] Wireless charging technology originates from wireless power transmission technology. It refers to a technology in which a battery-powered device does not need the aid of electrical wires but uses the principle of electromagnetic wave induction or other related AC induction technologies to send and receive induced AC signals with corresponding equipment at the sending and receiving ends for charging.

[0003] The existing bonding device of the magnetic isolation sheet for wireless charging can refer to the Chinese utility model patent with the authorization announcement number CN213321794U, which discloses a bonding device of the magnetic isolation sheet for wireless charging. The bonding device of the magnetic isolation sheet for wireless charging includes: a first steering roller, a plurality of first steering rollers, and a plurality of first steering rollers are arranged at intervals in the vertical direction, and each first steering roller is used for winding and steering a piece of magnetic isolation sheet strip; a solution tank, which is arranged downstream of the first steering roller and is used to contain the glue solution, and a sinking roller is arranged in the solution tank, and the magnetic isolation sheet strips on the plurality of first steering rollers are stacked on the sinking roller for dipping in glue, so that the plurality of magnetic isolation sheet strips become one; an embossing roller group, which is arranged downstream of the solution tank, includes an embossing roller and a flat roller which are arranged oppositely, and the embossing roller and the flat roller cooperate to make the embossing roller press cracks on the magnetic isolation sheet strip; an oven, which is arranged downstream of the embossing roller group and is used to dry the magnetic isolation sheet strip after dipping in glue. The laminating device of the utility model can reduce the thickness of the magnetic isolation sheet and can make the insulation effect between the fragment units of the magnetic isolation sheet better after being split.

[0004] When the above equipment is in use, the embossing roller and the flat roller are arranged, and the embossing roller and the flat roller cooperate to make the embossing roller press cracks on the magnetic isolation sheet strip; the drying oven is arranged downstream of the embossing roller group, and is used to dry the magnetic isolation sheet strip after being dipped in glue.

[0020] At the same time, an internal protective bushing 7 is glued to the inner wall of the fixing clamp body shell 1, and the internal protective bushing 7 is symmetrically distributed on the inner wall of the fixing clamp body shell 1. At the same time, since the internal protective bushing 7 is mainly made of EPE pearl cotton material, when the decorative material is in contact with the internal protective bushing 7 for fixing and gluing, the internal protective bushing 7 can effectively avoid wear between the outer wall of the material and the fixing clamp body shell 1, causing external damage to the material, thereby affecting the overall aesthetics of the material, and sliding guide blocks 6 are welded to the outer walls of both sides of the fixing clamp body shell 1.
