Detailed description of the invention
In order to be more clearly understood that the technology contents of the present invention, describing in detail especially exemplified by following example, it limits the scope of the invention only for purpose of being best understood from present disclosure.
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, a kind of flexible PCB extremely rolls over measurement jig, including the fixing plate 5 of 1, two side plate 2, pressing cover plate 3, product gripper shoes 4 of a base plate and a precompressed, two described side sheet rooms are fixedly arranged on described base plate every setpoint distance, and described product gripper shoe is fixedly arranged between two described side plates；Two described side plates are equipped with a vertical chute 21 near its front end, described pressing cover plate both sides are equipped with a pivot 31, two described pivots slide up and down to be located in two described chutes, and described pivot can rotate in described chute, when described pressing cover plate slides into the rotation of described chute upper end, can be pressed in described product gripper shoe；The fixing plate of described precompressed can be inserted between two described side plates and be pressed in described product gripper shoe, and can extract out between two described side plates.So, by product gripper shoe being fixed between two side plates, define the platform of an accommodating flexible PCB, flexible PCB can be carried out spacing by the part that two side plates exceed product gripper shoe, by coordinating of the chute of the pivot of pressing cover plate and side plate, location pressing can be realized affix one's seal, and can drive flexible PCB repeatedly around folding 180 °, complete extremely to roll over test.Its operation principle is as follows: first, by FPC and RFPC bending region while being defined as standing part, bending region another side is defined as movable part, when extremely rolling over, the standing part of FPC and RFPC is bonded at above product gripper shoe, makes just front end to product gripper shoe, the bending region of FPC and RFPC, then, fixing for precompressed plate is inserted between two side plates, and pushes down the standing part of FPC and RFPC with the fixing plate of precompressed, tentatively fix；Then, operator are with after portable pressing cover plate to the top of chute, driving pressure closing lid plate rotates clockwise 90 °, now the movable part of FPC and RFPC under the drive of pressing cover plate to standing part bending, when pressing cover plate plate fixing close to precompressed, fixing for precompressed plate is extracted out, and make pressing cover plate be pressed in above the movable part of FPC and RFPC, at this moment, the movable part of FPC and RFPC bends 180 °, R angle approximates 0 °, and this is bent to first time.Then, pressing cover plate is turned round 90 ° round about, the movable part of FPC and RFPC is set level gently, pressing pressing plate reverts to initial position, repeatable first time bending step, such as, bending action repeats to do 3 times, then product is repeated in turn bending 3 times, microscopic examination outward appearance after bending 3 times, turns white without color, and open lines etc. is bad, namely meet and extremely roll over test request, can open a way whether OK with circuit tester test if desired.
Preferably, at a distance of setpoint distance between top and the described base plate of described product gripper shoe and two described side plates, and the front end of described product gripper shoe inside contracts setpoint distance relative to the front end of two described side plates.
Preferably, described side plate is provided with the operative tip of chute and upwardly extends two projections 22 of formation, and described chute top extends in this projection and do not break through the top of this projection.As such, it is possible to make pressing cover plate exceed product gripper shoe, meet the needs driving product to carry out 180 degree of bendings.
Preferably, described pressing cover plate is provided with handle 6, and described handle is arranged near the top middle portion of described pressing cover plate.So, rotation pressing cover plate is lifted by the personnel of being convenient to operation that shake hands.
Preferably, described pivot is arranged near the bottom of described pressing cover plate.So, the lift of pressing cover plate can drive product to carry out 180 degree of bendings around pivoting after getting up.
Preferably, the front end of two described side plates is provided with the front apron rotated for preventing described pressing cover plate from leaning forward.So, can prevent pressing cover plate from turning forward by baffle plate.
Preferably, described product gripper shoe both sides are removably fixed on two described side plates each through at least two bolt.So, the Fast Installation between side plate and product gripper shoe can be realized by bolt.
Preferably, the fixing plate of described precompressed is provided with some backstop 51 for limiting its insertion distance near its rear end.So, can limit, by backstop, the distance that the fixing plate of precompressed inserts, it is prevented that the fixing plate of precompressed inserted deep rear secondary adjustment.
Above example is with reference to accompanying drawing, to a preferred embodiment of the present invention will be described in detail.Those skilled in the art by carrying out amendment on various forms or change to above-described embodiment, but when without departing substantially from the essence of the present invention, all drops within protection scope of the present invention.
