Specific embodiment
To make those skilled in the art more fully understand technical solution of the present invention, the present invention is mentioned with reference to the accompanying drawing
The attachment device being used in lighting test and lighting test equipment supplied is described in detail.
Fig. 1 is a kind of structural schematic diagram for the attachment device in lighting test that the embodiment of the present invention one provides, Fig. 2
To carry out schematic diagram when lighting test using attachment device shown in Fig. 1, as depicted in figs. 1 and 2, which is used in point
Lighting machine 9 is electrically connected with the PCB in panel 7 to be tested during lamp test, wherein the first of lighting machine 9 and lighting wire rod 8
End connection, which includes: main body 1, lighting wire rod socket 2, signal transmssion line material 3 and adapter 4, lighting wire rod socket
2 are set to the first surface in main body 1, the first end of lighting wire rod socket 2 be used for during lighting test with lighting wire rod 8
Second end connection；The first end of signal transmssion line material 3 is electrically connected with the second end of lighting wire rod socket 2；The first of adapter 4
End is removably connect with the second end of signal transmssion line material 3, the second end of adapter 4 for during lighting test with
Lighting test interface (not shown) connection on PCB.
It should be noted that the signal transmssion line material 3 in the present invention is the wire rod with conducting function, such as flexible circuit
Plate.
Before lighting test starts, the second end of lighting wire rod can be inserted into lighting wire rod socket 2, by adapter 4
Second end be inserted into the lighting test interface of the PCB in panel 7 to be tested；During lighting test, lighting machine 9 is generated
Point modulating signal, pass sequentially through lighting wire rod 8, lighting wire rod socket 2, signal transmssion line material 3, adapter 4, lighting test and connect
Mouthful, it is finally transmitted in PCB, so that display panel 7 to be tested is lighted, to carry out lighting test；After lighting test, only
Lighting test interface of the adapter 4 from PCB need to be extracted.Before in progress, lighting test starts next time, then will switching
First 4 are inserted into the lighting test interface of corresponding PCB.
By above content as it can be seen that continuing pair during carrying out lighting test using attachment device provided by the invention
Adapter 4 carries out plug operation, and lighting wire rod 8 can maintain always the state connecting with lighting wire rod socket 2, i.e., without to point
Lamp line material 8 carries out repeating to plug operation, to can effectively avoid the damage of lighting wire rod 8, effectively increases making for lighting wire rod 8
With the service life, and then the replacement frequency of lighting wire rod 8 is reduced, reduces testing cost.In addition, with the increase of testing time, switching
First 4 will appear damage.In the present invention, since adapter 4 and signal transmssion line material 3 use detachable connection method, thus it is straight
It connects and the adapter 4 of damage is removed and replaced.In the present invention, due to the replacement relatively convenient of adapter 4 and just
Preferably, thus the working efficiency of lighting test can be effectively improved and reduce cost.
In practical applications, when adapter 4 being carried out plug operation, it inevitably will drive signal transmssion line material 3, with
The increase of testing time, the phenomenon that signal transmssion line material 3 also will appear abrasion, aging, needed at this time to signal transmssion line material 3
It is replaced.For convenience of the replacement of signal transmssion line material 3, in the present embodiment preferably, the first end and point of signal transmssion line material 3
The second end of lamp line material socket 2 removably connects.When detecting that signal transmssion line material 3 damages, directly by damage
Signal transmssion line material 3 is disassembled from lighting wire rod socket 2 and adapter 4, and new signal transmssion line material 3 is replaced
?.
During practical lighting test, since 7 size of display panel is larger, needs testing staff's both hands to take screen, examine at this time
Survey personnel do not have extra hand to carry out support connection device, and attachment device is in tenesmus state, are easy to appear 3 quilt of signal transmssion line material
Pull apart, socket loose or dislocation the phenomenon that, be easy to appear letter in short, test process so as to cause 3 service life of signal transmssion line material
The problems such as number bad.
In order to solve the above technical problems, the third surface in the present invention in main body 1 is provided with a fixed structure 5, this is solid
Determine structure 5 to be used to that main body 1 and panel 7 to be tested to be fixed and (can be fixed with the backlight of panel 7 to be tested), testing staff
When both hands take screen, attachment device is lifted with panel 7 to be tested, drawing force is not present on signal transmssion line material 3, so as to effective
Avoid the problem that signal transmssion line material 3 be torn, socket loose or dislocation, ensure that being normally carried out for lighting test.
Further, fixed structure 5 includes: several suckers (attached drawing is merely exemplary to depict a sucker).Wherein, it inhales
The fixed part of disk can be fixed on the third surface of main body 1, and the adsorption section of sucker is backwards to third surface, to adsorb panel 7 to be tested
Backlight.
It should be noted that in the present embodiment the technological means of fixed structure 5 including sucker only play the role of it is exemplary,
Limitation will not be generated to technical solution of the present invention, there can also be fixed (for example, double faced adhesive tape) using other in the present invention
By main body 1 and panel 7 to be tested, no longer illustrate one by one herein.
In addition, in attached drawing 1 based on first surface and third surface on apparent surface the case where only play exemplary work
With, will not to technical solution of the present invention generate limitation.In the present invention, since third surface will be carried out with panel 7 to be tested
It is fixed, thus be unsuitable for set-point lamp line material socket 2, so only needing to guarantee first surface in the present embodiment and third surface is not
Same surface.
During lighting test, although being fixed between panel to be tested 7 and main body 1 by fixed structure 5,
It is to be placed in due to PCB outside panel 7 to be tested, PCB also can be easy to appear at this time flip chip in the state of tenesmus
The phenomenon that being broken (COF Crack), i.e., product has occurred bad during the test.
In order to solve the above technical problems, the attachment device further include: printed circuit board clamp 6, printed circuit board clamp 6 with
Main body 1 is fixed, for clamping PCB during lighting test.In the present embodiment, pass through fixed structure 5, main body 1, printed circuit
Board clamp 6 can maintain the fixation of attachment device, display panel 7 and PCB three, cover to can effectively avoid in test process
Brilliant film breaks.
Fig. 3 is the structural schematic diagram of printed circuit board clamp in Fig. 1, as shown in figure 3, the printed circuit board clamp 6 includes:
First support bar 61, second support bar 62 and clamp structure 63, wherein the first end and main body 1 of first support bar 61 are fixed, the
The first end of the second end and second support bar 62 of one support rod 61 is fixed, and rotation is provided in the first end of second support bar 62
The extending direction of axis 64, the rotary shaft 64 is vertical with third surface (surface where fixed structure), and rotary shaft 64 can be with respect to second
