Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing pairThe utility model embodiment is described in further detail.
As depicted in figs. 1 and 2, the utility model provides the bending aging survey in batches of a kind of flexible display screenExamination equipment, comprises and is positioned at first transmitting device 1 on upper strata, the second transmitting device 2 that is positioned at lower floor and positionBeing formed by multiple parallel axis of rolling 31 between the first transmitting device 1 and the second transmitting device 2Lateral bending roller group 3, the first transmitting devices 1 and the second transmitting device 2 include upside transport tape and downside passesDefeated band, the upside transport tape of the downside transport tape of the first transmitting device 1 and the second transmitting device 2 is parallelBe wound in the periphery of multiple axis of rolling 31; The flexible display screen of surveying 4 entered by one end of lateral bending roller group 3Enter to be between parallel two transport tapes, after multiple axis of rolling 31, exported by the other end of lateral bending roller group 3.
The first transmitting device 1 wherein comprises the first drive motors (not indicating in figure), is positioned at lateral bendingMounting bracket 12 and first endless conveyor belts 13 of roller group 3 tops, two ends, difference on mounting bracket 12Setting at least two groups are upper and lower spaced pair roller group 11, the first endless conveyor belts 13 and run through successively eachPair roller group 11 and multiple axis of rolling 31. And the second transmitting device 2 comprises that the second drive motors is not (in figureIndicate), be positioned at live-roller 21 and the second endless conveyor belts 22, the second ring at lateral bending roller group 3 two endsShape transport tape 22 is wound in successively and is positioned at the live-roller 21 at two ends and the periphery of each axis of rolling 31.Two transmitting devices have respectively independently drive motors to drive, and in the time carrying, keep two transmitting devices in phaseWith transmission speed, the drive motors in the present invention all adopts variable speed driver, the transmission speed of transport tape,Elasticity is all adjustable. For the impact of stress and frictional force in minimizing transmission, two transmitting devices in the present inventionAdopt upper and lower two-layer transmission form, flexible display screen is in upper and lower transport tape intermediate transport, and endless conveyor belts passesChances of losing games material is consistent; And multiple axis of rolling can, according to the radius requirement of test flexible display screen, rollThe size Selection of moving axis and replacing; Wherein the made position of each axis of rolling is adjustable, its upper and lower and position, left and rightPut all and can change, the axis of rolling 31 is wherein selected low-frictional force, oilless bearing, avoids frictional force and oilThe dirty impact on flexible display screen.
In Fig. 2, the axis of multiple axis of rolling 31 is in the same plane, and it is by 2～50 axis of rolling 31Composition lateral bending roller group 3, can certainly, by changing the position of certain several axis of rolling, be located at differencePlane on.
For avoiding the impact of outer gas stream and environment, as shown in Figure 3, the first transmitting device 1, the second biographyConveying device 2 and lateral bending roller group 3 are positioned at the casing 6 with metal housing 5, in casing 6, be provided with forKeep the constent temperature heater 7 of casing 6 interior constant temperature. Constent temperature heater 7 can use heater strip or heating plate shapeFormula heating, also can adopt other form to heat. Install in the both sides, inside of metal housing 5 or up and downHeater, ensures inner constant temperature and temperature capable of regulating, to meet process requirements.
In the time of concrete test, open respectively the first drive motors and the second drive motors, it is driven respectivelyThe first endless conveyor belts 13 and the second endless conveyor belts 22 move; By flexible display screen 4 from lateral bending roller groupThe axis of rolling 31 of 3 one sides enters, and exports from the axis of rolling 31 of opposite side, can well realize in batchesThe bending burn-in test of flexible display screen 4. Flexible display screen 4 is along the periphery laminating of the axis of rolling 31Time, its radius of curvature is identical with the radius of multiple bending axis of rolling 31, curved in existing in test processSong, has again out-of-plane bending, can not produce cumulative effect in BENDING PROCESS, has eliminated stress in BENDING PROCESSImpact, meet the demand of volume production for flexible display screen 4 bending burn-in tests.
Obviously, above-described embodiment is only for example is clearly described, and not to embodimentRestriction. For those of ordinary skill in the field, can also do on the basis of the above descriptionGo out other multi-form variation or variation. Here without also giving thoroughly all embodimentsLift. And the apparent variation of being extended out thus or variation are still in protection domain of the present utility modelAmong.
