In the supporting surface and close to one end of the loading end, so that the tool of fixed capacity screen is with being used for testing capacitor screen
The integrated structure of test circuit plate shape, carried out without individually test circuit plate is arranged on tool again during in order to test
Test job.Can be that test circuit is positioned at by institute by additional equipment alternatively, it is also possible to be interpreted as the test circuit plate
State supporting surface and carry out test job close to one end of the loading end, separate itself and jig body after test job terminates
Place.
Referring to Fig. 2, for example, in order to further press flexible PCB on the test circuit plate with strengthen survey
Effect is tried, the display screen measurement jig also includes press part 700, and the press part 700 is actively connected to the test electricity
On road plate 400.For example, the press part can have pressure head or briquetting of insulating properties etc., because the press part is exhausted
Edge material, therefore the circuit problems such as electrostatic or short circuit can be avoided to cause damage flexible PCB 500, avoid short circuit from tying test
Fruit impacts.So when the press part compresses test circuit plate, the test job to capacitance plate is not affected.Pass through
The press part is individually forced on flexible PCB so that flexible PCB is more efficiently pressed in the test circuit
On plate, abundant engaged test is carried out with leaving no gaps to realize, to increase test effect.
For example, in order to relatively easily cause flexible PCB to be connected on the test circuit plate, the test circuit
Plate 400 is arranged at the supporting surface 120 close to one end of the loading end 210.It is understood that due to soft on capacitance plate
Property circuit board length it is smaller, after pull-up bending, may be set due to the test circuit plate distant and can not make
Golden finger on flexible PCB directly can not be contacted fully with the golden finger of the test circuit plate, therefore by the survey
When examination circuit board is disposed in proximity to carry one end of the loading end of capacitance plate so that flexible PCB is apart from the test electricity
Road plate is closer to the distance, in order to relatively easily realize that flexible PCB docks with the effective of test circuit plate, in favor of
Carry out effective test job.
For example, in order to effectively limit capacitance plate, it is set to be arranged in the angle kept out between face and the loading end
Interior, the angle kept out between face and the loading end is less than 90 degree, more preferably, wherein described keep out face and the loading end
Between angle be more than 25 degree less than 80 degree.For example, the angle kept out between face and the loading end is 45 degree or 30 degree
When, the thickness of most of display screens on the market is so can adapt to, because the display screen of different-thickness is along the loading end
During slide downward, accordingly the different angles kept out among face and the loading end can make it that display screen is downward
Slide by fixed depth difference, for example, when the angle is less than 30 degree, because angle is smaller, if placing larger thickness
Display screen then display screen can put in the depth of the angle can be relatively shallower, due to be provided with one end of flexible PCB away from
From the loading end farther out, so it is difficult to be bent abutting to the loading end in pull-up flexible PCB, and can not incites somebody to action
The golden finger of the test circuit plate is effectively connected together with the golden finger on the flexible PCB and influences to test work
The effective progress made.If on the contrary, the angle kept out between face and the loading end is more than 90 degree, such that supporting surface
Gear is on the flexible PCB so that test circuit plate that flexible PCB cannot connect on the supporting surface and can not
Realize effective test job.Therefore when capacitance plate is positioned on the loading end, under the design of such angle, electric capacity
Screen can be stably fixed in the angle kept out between face and the loading end, and the now flexibility on capacitance plate
Circuit board can be abutted effectively to the test circuit plate when pull-up is bent, to realize the test job of relative efficiency.Separately
Outside, in order to effectively fix capacitance plate and be easy to so that flexible PCB and capacitance plate are separated, the supporting surface perpendicular to
Described to keep out face, the supporting surface is parallel to horizontal plane.It is understood that stop when capacitance plate is connected to described keep out on face
Only continue to slide so as to be stable at it is described keep out between face and the loading end, now pass through pull-up flexible PCB and direction
During the direction bending of the supporting surface, flexible PCB can be achieved and be in the test circuit plate in same level, not only
Be advantageous to the test circuit plate stably to place, also allow for test job and more efficiently carry out.
In order to form the structure that can limit capacitance plate, referring to Fig. 3, in another embodiment, the testboard 100
It is arranged at intervals with the supporting body 200, the face of keeping out is arranged at intervals with the loading end.It is understood that the carrying
Body has a certain distance with the testboard, i.e., wherein carries the loading end of capacitance plate with inclining for limiting capacitance plate edge
What the oblique loading end slided keeps out the distance with certain size between face.It can be appreciated that the display screen test is controlled
Tool is co-operatively completed to limiting for capacitance plate position and entering for false pressure test job by two separate structures
OK.Referring to Fig. 4, in another embodiment, the testboard is connected with the supporting body, it is described keep out face 110 with it is described
Loading end 210 connects.I.e. described testboard is close together to form an integral structure as to capacitance plate with the supporting body
The tool of vacation pressure test, specifically, the testboard and the supporting body are integral type mechanism, wherein the testboard with it is described
Supporting body is two parts of integral type tool, or it is also understood that the supporting body and the testboard are connected with each other,
Between there is connecting line, for example, together with the supporting body is mutually attached at the testboard, or the supporting body and the survey
Test stand is close proximity to together with mutually leaving no gaps, wherein the supporting body and the testboard are two single structures.
For example, for the ease of placing capacitance plate 300, and so as to along the loading end slide downward and nothing naturally
External force need to be applied to be defined its position, the supporting body has triangular-section.For example, the supporting body has isosceles three
Angle section, for example, in the present embodiment, the loading end favour it is described keep out face, for example, on the section of supporting body 200,
The loading end 210 is a side of triangle supporting body, and the base of supporting body is used to be connected to horizontal plane, so, when holding
When the base of carrier is placed in the horizontal plane so that carrying body position can firmly be placed, and the loading end favours
Horizontal plane so that the capacitance plate being positioned on the loading end slide downward and can be finally positioned naturally along gravity direction
Kept out in described between face and the loading end, so just eliminate the implementation individually fixed to the position of capacitance plate or pass through
Fixed by external force.So that detection work becomes simpler easily operated, i.e., pull-up flexible electrical is only needed in test process
Road plate simultaneously bends the golden finger for making it be connected on the test circuit plate to the test circuit plate, more convenient so as to realize
Test job.
