Embodiment 1
As shown in Figure 1, a kind of car trim processing technology comprising following steps:
S1, injection-moulding step: plastic particles are passed through into mold extrusion forming at high temperature under high pressure；
S2, it goes to destatic step: the electrostatic that removal decoration surface generates in injection molding process；
Preventing from hindering in coating leads to due to electrostatic resistance plating material is quick-fried to have splashed plating area in plating materials process, make
Material is plated with the presence of resistance in plating area after the completion of must being electroplated, and then leads to the failure of entire decoration processing；Prevented also from decoration
Absorption of the electrostatic to dust on part, causes decoration surface to be covered with dust.
S3, coating resistance plating material step: resistance plating material in region coating is plated into the resistance for removing the decoration after destaticing；
In order to prevent decoration surface be all electroplated all areas in electroplating process, so needing to being not required to
The region being electroplated, i.e., when being mounted on decoration on automobile, the position connected with automobile (is not exposed outside
Region)；Upper plated material would not be electroplated during plating after hindering plating material to these region coatings.
S4, plating step: the plating area for being coated with the decoration of resistance plating material is electroplated.
The decoration of injection molding is mainly passed through ion field and then neutralizes decoration surface by the step of going to destatic
Electrostatic ionic, realize decoration surface on electrostatic ionic removal.
During decoration passes through ion field, the ion in ion field can be scattered in decoration surface, by with dress
The removal to electrostatic ionic on decoration surface is realized in the neutralization of the positively charged or negatively charged electrostatic on gadget surface.
The step of going to destatic specifically includes the following contents:
S21, the decoration of injection molding is placed on conveyer belt by mechanical gripper；
S22, the decoration complete the removal of the decoration surface electrostatic as conveyer belt is by the ion field.
Ion field for neutralizing the decoration surface electrostatic ion is generated across an electrostatic removal device, and described is quiet
Electric removal device includes an electrostatic rod with holes that can generate ion, and ion is sprayed from the ion hole in the electrostatic rod with holes
It penetrates to form ion field.
It also needs the electrostatic removal device being mounted on the conveyer belt before going to destatic step described in the progress
At middle part or latter half of position.
Wherein, there are two brackets for the both ends connection of the electrostatic rod with holes, are installed in the biography by two brackets
It send at the medium position or latter half of position of band.
The electrostatic removal device further includes air pump and tracheae；The air pump by the tracheae with it is described with holes quiet
Torch connection；The ion that the electrostatic rod with holes generates is sprayed from ion hole by the size that the air pump controls air-flow
Ion field is formed out.
One is offered in the electrostatic rod with holes and is discharged from sub-aperture, and the ion field is by from the electrostatic rod with holes
On ion hole in vertically to the ion field perpendicular to the conveyer belt of the spouting formation of conveyer belt.
Wherein, the size in each ion hole can be set by oneself, and the diameter in general ion hole is less than 5mm, it is preferable that from
The diameter of sub-aperture is 3mm.
The distance between each ion hole opened up in the electrostatic rod with holes is equal, and the length for being discharged from sub-aperture is greater than
And be equal to the conveyer belt width, i.e., outermost two ion holes be located at the conveyor belt two sides edge surface or
Outside right above the conveyor belt two sides edge；So that the width of the ion field formed is greater than and is equal to the biography
Send the width of band.
The ion field that the electrostatic rod with holes generates is the ion field with same charge, including positively charged ion
Field or negatively charged ion field.
Because electrostatic includes positively charged electrostatic and negatively charged electrostatic, so if to neutralize electrostatic on decoration
The charge of the ion institute band of ion field and the opposite charge of electrostatic institute band are needed, when on decoration being positively charged electrostatic,
The electrically charged ion institute of ion field is negative electrical charge；When on decoration being negatively charged electrostatic, the ion of ion field is charged
Lotus is positive charge；And the electrostatic that decoration generates in injection molding process be positive charge or negative electrical charge be it is fixed, will not
Change because the type difference of processing decoration part is different with the time.
The resistance plating region of decoration in the coating resistance plating material step is that the decoration surface is contacted with automobile
The position of connection.
In order to prevent decoration surface be all electroplated all areas in electroplating process, so needing to being not required to
The region being electroplated, i.e., when being mounted on decoration on automobile, the position connected with automobile (is not exposed outside
Region)；Upper plated material would not be electroplated during plating after hindering plating material to these region coatings；In general
Resistance plating region is to connect the positions such as bayonet and the buckle of installation on decoration with automobile.
Wherein, the plating area in the plating step is all areas in addition to resistance plating region, in general
For decoration after installing all regions being exposed outside.
Embodiment 2
As shown in figs 2-4, to be mounted on generating on automobile when being mainly used for and reducing the engine operation of motor vehicle
The condition of production of the noise automotive muffler 5 months 8 to December, wherein 8 to November be using conventional machining process not into
The removal of row electrostatic, due to the fraction defective (i.e. disqualification rate) that electrostatic causes " flying oil " and generates, substantially all 1% or more, highest
When even solve 2%；And December is using the condition of production in two weeks after the processing technology after improving, fraction defective is significantly
It reduces, only 0.4%~0.5%, relative to the fraction defective 1%~2% of conventional machining process, using its production of technique of the invention
The production qualification rate of product is greatly improved.
The foregoing is merely the present invention/invention embodiments, are not intended to limit the present invention/invention the scope of the patents, all
It is directly or indirectly to be transported using equivalent structure or equivalent flow shift made by the present invention/description of the invention and accompanying drawing content
It similarly include in the present invention/invention scope of patent protection used in other related technical areas.
