Description
Technical field
The present invention relates to mobile phone connector bonding technology fields, the more particularly to bonding of liquid-state silicon gel and stainless steel adapting piece
Technique.
Background technology
Mobile phone connector is that on the outside then gluing passes through liquid-state silicon gel sulfidization molding, liquid-state silicon gel and stainless to stainless steel part
The bonding of steel part can play the role of sealing, dustproof and waterproof, so requiring the cementation of junction very high.If connection
The cementation insufficient strength at place, just will appear fall off, leak a series of problems, such as, these problems are ten for the use of mobile phone
Divide serious.Existing processing technology can not ensure the adhesion strength of stainless steel adapting piece and liquid-state silicon gel so that subsequently make
Occur silica gel repeatedly in fall off lower phenomenon, has seriously affected the experience of user.
Invention content
In order to overcome the deficiencies of existing technologies, the present invention provides a kind of bonding work of liquid-state silicon gel and stainless steel adapting piece
Skill can avoid the appearance of existing issue by the technique.
To achieve the goals above, the present invention provides following technical scheme：
The bonding process of liquid-state silicon gel and stainless steel adapting piece, includes the following steps：
1）Cleaning：Stainless steel adapting piece is put into alcohol and is cleaned, quantity 1000pcs, the time keeps 2 ~ 5min；Stainless steel is connected
The appearance of fitting is dirty to be washed, and generally use directly impregnates and stirs the greasy dirt for making stainless steel adapting piece appearance several times.
2）Baking：By cleaned stainless steel adapting piece be put into temperature be carried out in 105 ± 5 DEG C of oven baking 15 ~
30min；Alcohol is vapored away by high temperature, subsequent glue-line is made to will not fall off；
3）Gluing：In the stainless steel adapting piece surrounding gluing roasted；The glue is directly to buy, using manually-operated mode
Gluing, the glue-line are not generate obscission in order to which stainless steel adapting piece and liquid-state silicon gel to be bonded together；
4）Secondary baking：By the stainless steel adapting piece of coated glue be put into temperature be carried out in 105 ± 5 DEG C of oven baking 30 ±
5min；Glue-line baking is dried；
5）Vulcanization：The stainless steel adapting piece that baking finishes is put into mold, injecting liquid-state silicon gel by the runner of mold will produce
Product are sulfided into cavity shape；Make to be enclosed with liquid-state silicon gel on the outside of stainless steel adapting piece by mold and forms fixed shape；
6）Post-cure：The product vulcanizated is put into oven and carries out post-cure, oven temperature is 135 ± 5 DEG C；Revulcanization
The intensity for increasing liquid-state silicon gel, makes its vulcanization more thoroughly be unlikely to deform；
7）Deburring：The good product of post-cure is subjected to appearance detection, and is cleared up extra flash by deburring jig；
The flash of product is removed by deburring jig；
8）Full inspection：Product after deburring is detected the product machined using microscope detection appearance and size.
Further, the step 5）In curing temperature be 120 ~ 130 DEG C, vulcanization time be 30 seconds.
Further, the step 7）The time of middle post-cure is 30 ± 5min.
Further, the step 1）In alcohol be room temperature.
Advantageous effect caused by the present invention is：Suitable glue is selected, stainless steel adapting piece and liquid-state silicon gel are bonded
Get up, by sulfidation twice, adhesion strength can be increased to maximum, increase the waterproof seal of connector, also greatly
Ground reduces product obscission, and the expulsion rate of silica gel is made to drop to 1% by 15%.
