Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearer, below in conjunction with accompanying drawing and reality
Execute example the test fixture of the present invention is further elaborated.Should be appreciated that described herein specifically
Embodiment only in order to explain the present invention, is not intended to limit the present invention.
As it is shown in figure 1, a kind of test fixture, it is used for the bending strength to surface mount elements and/or the stripping of liquid crystal board
Testing from intensity, liquid crystal board includes slide and LCD panel, and slide includes bonding zone and non-adhering district, liquid
Wafer bonding is at bonding zone, and this test fixture includes pressure head 1, pressure head pin 2, bracing frame 3 and base plate 4；
Pressure head 1 and pressure head pin 2 are all connected with external computer strain gauge, and under the driving of external computer strain gauge
Move along a straight line；Bracing frame 3 includes the first work surface 5 and the second work surface 6；Arrange on first work surface 5
Supporting part 7, for the end of support sticker piece element, makes in the middle part of surface mount elements unsettled, and pressure head draws in external computer
Move to surface mount elements under the driving of power meter, and push suspension area in the middle part of surface mount elements；Base plate 4 includes the 3rd
Work surface 8；Bracing frame 3 and base plate 4 removably connect, and respectively by the second work surface 6 and the 3rd work
Liquid crystal board is gripped by face 8, and makes liquid crystal board part expose at the second work surface 6 and the 3rd work surface 8
Clip position outside, pressure head pin 2 moves to liquid crystal board under the driving of external computer strain gauge and pushes
The non-adhering district of liquid crystal board exposed parts.So can make this fixture can either be to the bending strength of surface mount elements
Test, the peel strength of liquid crystal board can be tested again, it is achieved that function two-in-one, entering
During the test of row both, it is not necessary to change fixture, i.e. save the time, improve work efficiency, simultaneously energy
Enough ensure the accuracy of test result.
As a kind of embodiment, the first work surface 5 and the second work surface 6 are oppositely arranged.So can
Reduce the volume of bracing frame 3, save space.
As a kind of embodiment, the 3rd work surface 8 arranging receiving portion 9, receiving portion 9 is shape and liquid
The brilliant suitable degree of depth of plate is less than the depression of liquid crystal board thickness.By the receiving portion 9 restriction to liquid crystal board position,
Bracing frame 3 and base plate 4 can be made to be clamped more by liquid crystal board by the second work surface 6 and the 3rd work surface 8
Firmly.When carrying out peeling off test, liquid crystal board will not occur from the active force of pressure head pin 2 because bearing
Change in location, it is ensured that the accuracy of test result.
As a kind of embodiment, bracing frame 3 arranging pin hole 10, pressure head pin 2 is through pin hole
10, and move along a straight line in pin hole 10.Pin hole 10 can be arranged on bracing frame 3 and liquid crystal board
The position that the non-adhering district of exposed parts is corresponding, by the pin hole 10 restriction to pressure head pin 2, makes pressure
Head pin 2 can be applied to active force the non-adhering district of liquid crystal board exposed parts in test process exactly
On, the accuracy of test, also ensure that the linearity that pressure head pin 2 moves, it is ensured that test job simultaneously
It is smoothed out.
As a kind of embodiment, bracing frame 3 includes that jut 11, pin hole 10 are arranged on jut
On 11.Jut 11 need not excessive, as long as disclosure satisfy that and arranging pin hole 10, so can subtract
The making materials of few bracing frame 3, and reduce the weight of bracing frame 3, not only save cost of manufacture, simultaneously
It is easy to personnel's operation to test fixture.
As a kind of embodiment, bracing frame 3 arranges through hole 12, base plate 4 arranges screw 13, logical
Hole 12 and screw 13 are corresponding；Screw through through hole 12 and is connected with screw 13, thus by bracing frame 3
Connection fixing with base plate 4.By screw, bracing frame 3 and base plate 4 are linked together, it is possible to ensure to support
It is firm that liquid crystal board is clamped by frame 3 and base plate 4, and be easily installed and dismantle, and operates very convenient.
As a kind of embodiment, the quantity of through hole 12 is at least two, screw 13 and the number of through hole 12
Measure identical, and with through hole one_to_one corresponding.So can make bracing frame 3 and base plate 4 that liquid crystal board is clamped more
Solid and reliable, it is ensured that being smoothed out of test.
As a kind of embodiment, supporting part 7 is and the first fixing cuboid being connected of work surface 5, and
And quantity is two or more.The two ends of surface mount elements are individually positioned on two supporting parts 7, middle
Formed unsettled, it is possible to ensure the stability of surface mount elements preventing and treating, operate the simplest.
As a kind of embodiment, the first work surface 5 arranges limiting section (not shown), is used for limiting patch
The position of piece element.When surface mount elements is placed on supporting part 7, the edge of surface mount elements abuts in spacing
In portion, the accuracy of surface mount elements placement location can either be ensured, be avoided that again surface mount elements is from support simultaneously
Landing in portion 7.
The test fixture of the embodiment of the present invention, has reasonable in design, simple in construction, with low cost, operation letter
Single, the advantage that counter-bending test can carry out peel strength test again can be carried out.
Embodiment described above only have expressed the several embodiments of the present invention, and it describes more concrete and detailed,
But therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that, for this area
Those of ordinary skill for, without departing from the inventive concept of the premise, it is also possible to make some deformation and
Improving, these broadly fall into protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be with appended
Claim is as the criterion.
