Description
Technical field
The utility model relates to waterproof mobile phone back cover air tightness test tool.
Background technology
There is now many moneys mobile phone to have several functions as making a phone call on the market, surfs the Net, send short messages game, but a fatal weakness is arranged, and is exactly can not waterproof, will damage in case be soaked in water, particularly in military affairs, the key areas such as flood control, waterproof mobile phone just seems and is even more important.There is following defective in prior art in daily productive life:
1, existing mobile phone is on rainy day, or accidentally falls in the water and all can cause short circuit, can not use.
2, waterproof mobile phone wants waterproof must accomplish that all parts combination afterwards can waterproof.
3, existing technology all can not be carried out the science test to mobile phone component.
4, must develop special-purpose tool the process of mobile phone component production is advanced (IPQC), guarantee cell-phone cover facility have water proofing property like this.
The utility model content
The utility model provides a kind of measurement jig that can effectively measure mobile phone battery cover waterproof effect and air-tightness in order to overcome the defective that exists in the background technology.
The technical scheme that its technical matters that solves the utility model adopts is:
Waterproof mobile phone back cover air tightness test tool comprises the precision plastic rubber mould, and described precision plastic rubber mould comprises cope match-plate pattern and lower bolster, and described cope match-plate pattern is connected guide pillar and is connected with lower bolster; Be provided with mold base on the described cope match-plate pattern, the cope match-plate pattern the inside arranges the cylinder starter gear; Be provided with die, locating piece and bottom on the described lower bolster and be provided with vacuum machine and vacuum table.
Described locating piece comprises positioning balance spring, limited block.
Be provided with sealing silica gel zone around the die of described lower bolster.
Cylinder drive cope match-plate pattern by worktable during work moves up, the staff closed cleaning door after the staff put into product to be measured, cope match-plate pattern moves down, after appraising and deciding, begin to vacuumize closing switch, the drop of concern vacuum meter instrument within the unit interval, drop is to meet the requirements in certain scope, otherwise just undesirable.
This practical patent has solved the waterproof test problem of mobile phone manufacturing process, also has without any manufacturer at home before this technology, and we are these technology of first hand Application and Development, makes waterproof mobile phone and just has been readily solved.
Description of drawings
Fig. 1 is one of working state schematic representation of the present utility model;
Fig. 2 is workflow diagram of the present utility model.
Embodiment
As shown in Figure 1, waterproof mobile phone back cover air tightness test tool comprises the precision plastic rubber mould, and described precision plastic rubber mould comprises cope match-plate pattern and lower bolster, and described cope match-plate pattern is connected guide pillar and is connected with lower bolster; Be provided with mold base on the described cope match-plate pattern, the cope match-plate pattern the inside arranges the cylinder starter gear; Be provided with die, locating piece and bottom on the described lower bolster and be provided with vacuum machine and vacuum table.
Described locating piece comprises positioning balance spring, limited block.
Be provided with sealing silica gel zone around the die of described lower bolster.
Cylinder drive cope match-plate pattern by worktable during work moves up, the staff closed cleaning door after the staff put into product to be measured, cope match-plate pattern moves down, after appraising and deciding, begin to vacuumize closing switch, the drop of concern vacuum meter instrument within the unit interval, drop is to meet the requirements in certain scope, otherwise just undesirable.
As shown in Figure 2, the detailed step of testing process is as follows:
The first step, cope match-plate pattern move upward under the drive of oil cylinder and open template;
Second step is put into product to be measured;
In the 3rd step, cope match-plate pattern matched moulds under the drive of oil cylinder compresses product;
In the 4th step, evacuator is started working, and the vacuum of pumping mode tool is turned off vacuum machine, checks that the changing value of vacuum table data within the unit interval determines whether product possesses water proofing property.
Take above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, the relevant staff can in the scope that does not depart from this utility model technological thought, carry out various change and modification fully.The technical scope of this utility model is not limited to the content on the instructions, must determine its technical scope according to the claim scope.
