The invention discloses a
magnet fixing method used on a magnetic therapy module. A special die is designed according to a required shape of the magnetic therapy module, a groove for storing a
magnet is formed in a corresponding position of a lower die of the die, an annular boss protruding outwards is arranged at the inside of the groove, and a positioning
magnet is arranged at the bottom of the groove of the special die; a layer of cloth capable of being subjected to butt fusion under the action of ultrasonic
waves is arranged on the lower die of the die, a magnetic block is placed on the membrane of the cloth, a layer of same cloth capable of being subjected to butt fusion under the action of ultrasonic
waves is arranged again on the magnetic block, an upper die of the die is placed on the cloth at the upper layer, the annular boss of the lower die and the plane of the upper die are compressed, an ultrasonic wave device of the die is started, and PVC or PU membranes of the two
layers of cloth are subjected to butt fusion at normal temperature by the ultrasonic
waves. The special die is adopted to place the magnet in the required position, the membrane
layers of the cloth are subjected butt fusion by vibrating through the ultrasonic waves, and since the membrane
layers of the upper and lower layers of cloth are subjected to butt fusion by the vibration of the ultrahigh-speed ultrasonic waves, the magnetic block is fixed between the upper and lower layers of cloth, an ideal fixing effect is achieved, time is saved and work efficiency is improved.
