[0039] 3) Apply a layer of hot melt adhesive to the surface of coil 314 to fix coil 314.

[0040] 4) Place the coil 314 into the placement box 309 and melt the hot melt adhesive at the parts of the coil 314 that need to be connected.

[0041] 5) After cooling it in the cooling box 401, bond the multiple coils 314 together.

[0042] In this embodiment, the pressure between the stamping cylinder 303 and the placement box 309 will not cause damage to the heating tube 308.

[0043] The loop segment 206 is bonded to the rotating column 204, and the loop segment 206 forms multiple coils 314.

[0044] The temperature in cooling box 401 is between zero and five degrees Celsius.

[0045] The magnetic disk assembly mechanism 5 includes a magnetic disk, and the magnetic disk assembly mechanism 5 assembles multiple or two coils 314 with the disk.

[0046] In this embodiment, the temperature of the stamping cylinder 303 and the heating tube 308 inside the placement box 309 is between 90 and 110 degrees Celsius, which facilitates the melting of the hot melt adhesive.

[0047] In this embodiment, water is filled between the bottom inner wall of the cooling box 401 and the second heat-conducting plate 409. A water inlet pipe and a water outlet pipe are fixedly installed on the outer wall of the cooling box 401. The water is cooled by the cooling pipe 402, and the temperature is conducted to the coil 314 by the second heat-conducting plate 409 so that the hot melt adhesive on it can solidify quickly.

[0049] In this embodiment, the heating time of the coil 314 by the stamping cylinder 303 and the placement box 309 is no more than twenty seconds.

[0050] The working principle of the above embodiments is as follows:

[0051] The wire segment on the loop segment 206 is attached to the inside of the coil groove of the rotating column 204. At this time, the loop segment 206 is quickly wound into multiple coils 314 by the action of the rotating motor 203. Then, the double-sided tape on the coil 314 is removed and hot melt adhesive is applied to the outer surface of the coil 314. After the hot melt adhesive cools and solidifies, the coil 314 is snapped onto the positioning column 310. At this time, the cover plate 313 covers the parts of the coil 314 that do not need to be hot-pressed. The base plate 306 is then pressed by the stamping cylinder 303. The lower box 309 moves inside. When the first heat-conducting plate 307 inside the base plate 306 comes into contact with the coil 314, the heating tube 308 heats up quickly to process the hot melt adhesive that needs to be fused on the coil 314. Then, multiple coils 314 are stacked inside the cooling box 401 to cool the multiple coils 314 quickly and solidify the hot melt adhesive. At this time, the coils 314 are fixed together to form a multi-coil. Then, the magnetic sheet on the magnetic sheet assembly mechanism 5 is used to install the multi-coil, thus completing the assembly step of the multi-coil.
