Title:
LASER CUTTING MANUFACTURING PROCESS FOR WIRELESS CHARGING COIL
Document Type and Number:
WIPO Patent Application WO/2019/169707
Kind Code:
A1
Abstract:
A laser cutting manufacturing process for a wireless charging coil, comprising the following steps: perform preliminary laser cutting on a copper foil, the preliminary laser cutting only being used for cutting partial areas of the copper foil, and arc-shaped copper wires being cut on the copper foil (S1); perform subsequent laser cutting on the copper foil, the subsequent laser cutting being used for cutting another partial areas of the copper foil, and the arc-shaped copper wires being cut on the copper foil (S2); the arc-shaped copper wires cut by means of the preliminary laser cutting and the arc-shaped copper wires cut by means of the subsequent laser cutting form a continuous spiral coil (S3). According to the manufacturing process, the arc-shaped copper wires cut by means of the primary laser cutting are basically kept on one plane with the copper foil, namely, no severe vertical falling phenomenon occurs, and therefore, operations such as rotating, conveying, or laminating can be carried out conveniently; then, the subsequent laser cutting is performed, the subsequent laser cutting is used for cutting another partial areas of the copper foil, and the arc-shaped copper wires cut by means of the preliminary laser cutting and the arc-shaped copper wires cut by means of the subsequent laser cutting form the continuous spiral coil, so as to realize manufacturing of the wireless charging coil.
