Description
Technical field
The present invention relates to machining process, relate more specifically to a kind of method for sealing shielding can.
Background technology
Along with the continuous quickening of social informatization process, various information household appliances such as STB, mobile phone or the like are constantly put on market.The radome that is used for various information household appliances is connected with at least one connector usually, and connector generally is fixed on the radome in the mode of riveting, so the slit has appearred in the junction of connector and radome inevitably.For the sealing that realizes radome to ensure its screening ability preferably, need after connector is fixed in radome, connect place, slit and carry out encapsulation process it.The following dual mode of the general employing of existing encapsulation process:
A kind of sealing means is pure handwork, manually uses electric iron that scolder (being generally the tin silk) is welded in the junction of connector and radome to realize its sealing.This manual welding mode causes face of weld out-of-flatness or not exclusively sealing easily owing to there is individual difference, and qualification rate is low and production efficiency is also low.
Another kind of sealing means is the operation of Reflow Soldering flowing water type, prior to place, the slit between radome and connector spot printing tin cream, then whole radome is put into similar streamline body of heater headed by this welding process, makes the tin cream fusing, reaches the scolding tin effect.Because scolder is to adopt tin cream, it is inhomogeneous and make face of weld out-of-flatness or not exclusively sealing to occur spot printing easily though the sealing mode can be enhanced productivity relatively, and qualification rate is low.In addition, this processing mode places whole radome in the streamline body of heater and transmits, and whole radome is in heated condition in the long period, be easy to generate magnetization phenomenon, and place the tin material of commissure past dirty, further cause tin material skewness, reduce qualification rate because of the effect of gravity.
Therefore, be necessary to provide the higher method for sealing shielding can of a kind of good sealing effect, qualification rate and production efficiency to overcome above-mentioned defective.
Summary of the invention
The purpose of this invention is to provide the higher method for sealing shielding can of a kind of good sealing effect, qualification rate and production efficiency.
To achieve these goals, the present invention proposes a kind of method for sealing shielding can, and it comprises: the radome that provides riveted joint that connector is arranged forms the assembling slit between described connector and the described radome; Provide and the corresponding Xi Quan of the shape in described slit; With described tin snare on the described connector and cover slit between described radome and the described connector; The high frequency that is connected with induction coil heater is provided, described induction coil is made and the corresponding shape of described tin circle, described connector is placed in the described induction coil, make described Xi Quan be positioned at the below of described induction coil, and described relatively induction coil inclination certain angle, thereby the magnetic field that described induction coil is produced is roughly the same in the intensity of described Xi Quan region; To produce magnetic field, described Xi Quan is heated fusing and fills described slit described high frequency heater in described magnetic field to described induction coil energising.
Preferably, the angle ranging from 2 ° to 35 ° the scope.Form an appropriate tilt angle between plane, induction coil place and the plane, described Xi Quan place so that the heat that is distributed on the Xi Quan is basic identical, Xi Quan can reach fusing substantially simultaneously, further improves welding effect.
Preferably, described tin snare was also being comprised before described connector: scaling powder is added in the junction at described connector and described radome.The interpolation of scaling powder can further improve welding efficiency and welding performance.
Preferably, method for sealing shielding can also comprises: described radome is cooled off with fan normal temperature in Xi Quan fusing back.
Compared with prior art, method for sealing shielding can of the present invention adopts the Xi Quan corresponding with the connector profile as scolder, and the tin snare is in covering slit on the radome on the connector exactly to guarantee the smooth of face of weld and the complete sealing of welding.In addition, adopt the high frequency heater that is provided with induction coil that Xi Quan is partly evenly heated, reduce heated perimeter and avoid radome to produce magnetization phenomenon, further improve qualification rate and productivity ratio.
