Triboelectricity device according to this utility model embodiment, by friction generator being placed in the annular seal space after upper diaphragm seal and lower seal film phonograph seal, and the edge of upper diaphragm seal and lower seal film corresponding lead outgoing position is fused with the wire of friction generator, thus wire can be in the fused layers of encapsulating film and wire core material entirely without gap, improve the sealing of device, realize the thorough encapsulation of the conductor part of electromotor, preferably meet the environmental condition of friction generator work, improve the service behaviour of friction generator.
Fig. 2 is the flow chart of the preparation method of the triboelectricity device according to this utility model embodiment.As in figure 2 it is shown, be directed to above-mentioned triboelectricity device, this preparation method comprises the following steps:
In step s 201, at least one friction generator is arranged in the chamber of upper diaphragm seal and the alignment placement of lower seal film.
Such as, friction generator clamping, friction generator is placed in the chamber that two panels encapsulating film is formed, and makes the first fusion border area of two panels encapsulating film, the second fusion border area alignment.
In step S202, by the edge weld beyond the corresponding lead outgoing position of upper diaphragm seal and lower seal film, to form edge fusion district.
Specifically, first carry out welding for the first time, the friction generator being coated with is placed in particular manufacturing craft, use sealed in unit to be welded together the first fusion area of two panels encapsulating film, form edge fusion district.
In step S203, chamber is inflated or exits, so that the air pressure in chamber reaches preset pressure value.Wherein, preset pressure value can be configured according to practical situation.
Wherein, chamber is inflated and the mode exitted can have a variety of, be the most directly inflated by the region of incomplete fusion and exit, or a gas channel is set is inflated and exits.
Further, secondly to carrying out tolerance control in chamber, by the breach of the second fusion position, border area of two panels encapsulating film, chamber is charged and discharged gas, to reach required air pressure.
As it has been described above, the medium being positioned in annular seal space can include gas, specifically, this medium can be preferably air, but, the mixture of other gas or the gas/do not have with air be also it is contemplated that.It is furthermore advantageous to can there is certain overvoltage in annular seal space, thus sealing member can adapt to different requirements.
In step S204, by the edge weld of the corresponding lead outgoing position of wire, upper diaphragm seal and lower seal film, to form wire fusion area.
It addition, finally carry out second time welding, use sealed in unit to be welded together the second fusion area of two panels encapsulating film, form wire fusion area.
Alternatively, in an embodiment of the present utility model, the preparation method of this utility model embodiment also includes: when to the welding of wire fusion area, the edge fusion district adjacent with wire fusion area is carried out welding again, to improve the sealing of device.
That is, the thickness of wire fusion area is not less than the thickness in edge fusion district, when the second fusion area welding of two panels encapsulating film, in order to ensure sealing effectiveness, secondary welding can be carried out for the edge fusion district that wire fusion area is adjacent, be further ensured that the sealing of triboelectricity device simultaneously.
Further, in embodiment of the present utility model, the weld time of wire fusion area is less than 5s less than the weld time in edge fusion district, the weld time of wire fusion area.Such as, the energising weld time of wire fusion area can be 0.1-0.5 times of the energising weld time in edge fusion district, and 5s can not be more than, thus the wire sheath of wire fusion area with friction generator is fused, improve the sealing of device, preferably meet the environmental condition of friction generator work, improve the service behaviour of friction generator.

Such as, selecting high frequency packaging machine to be packaged, encapsulation electric current can be 2-3A, and the energising weld time in edge fusion district can be 2.5s, is incubated compacting time 2s；The energising weld time of wire fusion area can be 0.3s, and the insulation compacting time can be 2s.
In addition, the wall thickness of upper diaphragm seal and the wall thickness of lower seal film can be different, therefore, the compressibility of sealing member or the deformation of sealing member can be in the mounted state according to being used for adaptation, because the region with relatively thick can not deform the most consumingly compared to the region with less wall thickness.
Such as, selecting PVC material encapsulating film, the material thickness in edge fusion district can be 0.3mm, and the material thickness of wire fusion area can be with 0.5mm, and the diameter of wire core can be with 0.8mm, and line skin is PVC material, and its thickness can be with 0.8mm.
Preparation method according to the triboelectricity device that this utility model embodiment proposes, by friction generator being placed in the annular seal space after upper diaphragm seal and lower seal film phonograph seal, and the edge of upper diaphragm seal and lower seal film corresponding lead outgoing position is fused with the wire of friction generator, thus wire can be in the fused layers of encapsulating film and wire core material entirely without gap, improve the sealing of device, realize the thorough encapsulation of the conductor part of electromotor, preferably meet the environmental condition of friction generator work, improve the service behaviour of friction generator.
Further, Fig. 3 is the flow chart of preparation method of the triboelectricity device according to another embodiment of this utility model.As it is shown on figure 3, be directed to above-mentioned triboelectricity device, this preparation method is further comprising the steps of:
In step S301, at least one friction generator is arranged in the chamber of upper diaphragm seal and the alignment placement of lower seal film.
In step s 302, carry out the edge at the edge beyond the corresponding lead outgoing position of upper diaphragm seal and lower seal film and corresponding lead outgoing position synchronizing welding, to form edge fusion district and wire fusion area respectively, wherein, in edge fusion district or wire fusion area, reserve gas channel.
In step S303, by gas channel chamber it is inflated or exits, so that the air pressure in chamber reaches preset pressure value.
In step s 304, gas channel is carried out welding.
Wherein, the preparation method of this utility model embodiment is with the difference of above-mentioned preparation method: wire welding area can synchronize fuse with edge weld district, but the correspondence position in edge weld district or wire welding area is reserved a gas and stayed passage.Specifically, alloying process is, first fusion wire welding area and edge weld district are synchronized, afterwards by the internal gas volume sealed up for safekeeping of gas channel adjustment to most suitable, so that reaching required air pressure in chamber, last welding gas channel, complete to close, and can again fuse gas channel at outside one determining deviation of gas channel, thus form two fusion points, seal gas in cavity between two fusion points up for safekeeping, thus increase the air-tightness of sealing member.
It should be noted that the aforementioned explanation to the preparation method embodiment of triboelectricity device is also applied for the preparation method of the triboelectricity device of this embodiment, for reducing redundancy, here is omitted.
Preparation method according to the triboelectricity device that this utility model embodiment proposes, by friction generator being placed in the annular seal space after upper diaphragm seal and lower seal film phonograph seal, and the edge of upper diaphragm seal and lower seal film corresponding lead outgoing position is fused with the wire of friction generator, thus wire can be in the fused layers of encapsulating film and wire core material entirely without gap, improve the sealing of device, realize the thorough encapsulation of the conductor part of electromotor, preferably meet the environmental condition of friction generator work, improve the service behaviour of friction generator.
