Description
Technical field
The present invention relates to FPC pressure head, belongs to OLED detection device technical fields, more particularly to a kind of for aligning crimping
FPC pressure head.
Background technology
In display technology field, Organic Light Emitting Diode (Organic Light-Emitting Diode, OLED) is aobvious
The technology of showing have the advantages that self-luminous, wide viewing angle, almost infinite high contrast, compared with low power consumption, high reaction speed, generally should
For in the display devices such as TV, mobile phone, tablet personal computer.With continuous improvement of the people to electronic equipment demand for control, have
The display device of touch controllable function receives more and more attention.Currently, in the display device of OLED technology has been used, control letter
Display device number is typically passed to by external circuits such as flexible PCBs (Flexible Printed Circuit, FPC), this is just
Need flexible PCB and OLED display binding (bonding), namely it is (i.e. golden by the PIN needle on flexible PCB
Finger) it is corresponding with display device pad (PAD points) binding so that signal is passed to display device from flexible PCB.When
When oled panel is crimped using PAD points with FPC PIN needle, there are 2 technical problems in it, first, oled panel area be
Fixed, because PAD point areas occupied are larger, then corresponding oled panel screen display area area will reduce, so as to reduce
The utilization rate of oled panel；Secondth, it is larger using the oled panel volume of PAD points itself and must be completed in the lighting of CELL sections
Module set section technique productions could be carried out again by carrying out cutting again afterwards, reduce production efficiency.With the continuous renewal of technology, OLED faces
Plate is in order to reduce size while improve the display area utilization rate of panel, typically by by original oled panel substrate material
Be changed to flexible base board, while cancel PAD points, use PIN needle instead, its structure as shown in Figure 1, because PIN needle is compared to PAD point energy
Enough panel areas for greatly reducing its occupancy, therefore should the flexible OLED panel effective display area domain accounting with multigroup PIN needle
Increase, it can largely save the manufacturing cost for saving oled panel；Efficiently solve the above-mentioned oled panel institute using PAD points
The problem of existing.
But the flexible OLED panel of multigroup PIN needle is carried for this kind, the spacing between two adjacent groups PIN needle is about
The width of each PIN needle in every group of PIN needle of 60~80um or so is about 60~130um, flexible OLED panel connection
The premise that lighting test can be carried out after FPC is that the PIN needle of flexible OLED panel and FPC PIN needle are mutually butted, therefore flexible
The connection of the exactitude position of the PIN needle of oled panel and FPC PIN needle is crucial, if both contraposition failures, occur flexibility
The PIN needle of oled panel and the contraposition connection failure of FPC PIN needle, loose contact during so as to cause flexible OLED panel to be tested.And
In the contraposition process of the PIN needle of flexible OLED panel and FPC PIN needle, typically calibrated on the basis of FPC PIN needle soft
The PIN needle position of property oled panel, so FPC PIN needle must be controlled to be located in the range of CCD camera lenses can find a view, protect simultaneously
The position for demonstrate,proving FPC PIN needle is unlikely to the compensation range for exceeding the machine of the position of the PIN needle of regulation flexible OLED panel；And
Common pressure head of the prior art is only used for fixing FPC PIN needle, can not ensure its installation site, simultaneously as pressure head
The end face that pushes typically be level, it is possible to cause the situation of FPC PIN needle short circuit flexible OLED panel.
The content of the invention
In view of the above-mentioned drawbacks of the prior art, in the prior art for installing FPC PIN needle pressure head without legal
Position FPC technical problem, the present invention propose a kind of pressure head for being used to align the FPC of crimping, and it is not only simple in structure, and can
FPC location and installation is rapidly realized, while avoids the situation of FPC PIN needle short circuit flexible OLED panel.
In order to solve the above technical problems, present invention employs such a pressure head for being used to align the FPC of crimping, it includes
Pressure head body and pressing plate, the pressing plate are connected to the pressure head body lower end；The pressure head body be used to installing FPC end with
FPC end shape matches；The alignment pin for positioning FPC is provided with the pressure head body and for protecting delaying for FPC
Punching pad.
In a kind of preferred embodiment of the present invention, the alignment pin has two, and described two alignment pins are parallel affixed
It is used for the lower end for installing FPC end in the pressure head body；Positioning hole in the installation site and FPC of described two alignment pins
Match.
In a kind of preferred embodiment of the present invention, described cushion pad one end is glued with the pressure head body, the other end
Match with the PIN needle end shape of the FPC.
In a kind of preferred embodiment of the present invention, the pressure head body includes connection floor and connection pressure head；It is described
Connection pressure head is removably attachable to the connection floor lower end.
In a kind of preferred embodiment of the present invention, the connection floor includes being used for the folder for connecting the connection pressure head
Hold portion and the connecting portion for connecting power source；It is provided with the lower surface of the clamping part for connecting the recessed of connection pressure head
Groove.
In a kind of preferred embodiment of the present invention, the side wall of the groove is wedge surface.
In a kind of preferred embodiment of the present invention, the lower surface of the connection pressure head is horizontal by an inclination angle.
In a kind of preferred embodiment of the present invention, the lower surface shape and FPC shape phase of the connection pressure head
Match somebody with somebody, alignment pin and cushion pad are connected with the lower surface of the connection pressure head.
The beneficial effects of the invention are as follows：The present invention is simple in construction, easy to install, and it on pressure head body by setting
Alignment pin realizes the pre-determined bit to FPC, and flexible OLED faces are adjusted so as to ensure that the position of FPC PIN needle is unlikely to exceed
The compensation range of the machine of the position of the PIN needle of plate；The present invention on pressure head body by increasing cushion pad simultaneously so that FPC
Good protection can be obtained during crimping, prevents impulsive force during crimping from causing its damage；The present invention is by by pressure head sheet
Body is designed as split-type structural, and connects pressure head alternatively while connect pressure head bottom and designed for non-horizontal surface, avoids FPC and exists
During crimping its PIN needle be in contact with remaining circuit outside flexible OLED panel PIN needle cause short circuit phenomenon (its operation principle is,
When flexible OLED panel PIN needle is located at face plate edge inner side and PIN needle directly also has other circuits with edge, according to level
When connection pressure head directly crimps, the remaining circuit connection of FPC PIN needle and flexible OLED panel will necessarily be caused short so as to cause
Road phenomenon)；The present invention ensure that connection pressure head with being connected floor by the way that the groove for connecting the clamping part of pressure head is designed as into wedge surface
Installation accuracy, make play will not occur during its connection.
