Embodiment
To combine the accompanying drawing among the utility model embodiment below, the technical scheme among the utility model embodiment will be carried out clear, intactly description.
The utility model provides a kind of bending fatigue testing machine, and this testing machine can carry out the bending fatigue test simultaneously to the multi-disc FPC.
As depicted in figs. 1 and 2, said bending fatigue testing machine comprises cabinet 1, is positioned at the drive unit 2 and the clamp device 3 of cabinet 1; The returning face plate 33 that clamp device 3 comprises the fixed head 32 that is fixed in the cabinet 1, be arranged side by side with fixed head 32 and be positioned at fixed head 32 and returning face plate 33 on how secondary bending anchor clamps 31; Returning face plate 33 is connected with drive unit 2.
With reference to figure 3 and Fig. 4, bending anchor clamps 31 comprise upper module 311, lower module 312, upper module cover plate 313 and lower module cover plate 314; Upper module 311 is positioned on the returning face plate 33 through 3 location PIN and 2 screws in module pilot hole 316 positions, and lower module 312 is positioned on the fixed head 32 through 3 location PIN and magnet; The intersection of upper module 311 and lower module 312 is the intersection of returning face plate 33 and fixed head 32; Because upper module 311 needs upset constantly in the cripping test process, therefore need to increase by 2 screws and strengthen fixing.Upper module cover plate 313 is pushed down soft board 7 backs and is positioned on the said upper module 311 through magnet, and lower module cover plate 314 is pushed down soft board 7 backs and is positioned on the lower module 312 through 2 location PIN and magnet.The quantity of location PIN, screw and magnet can change as required, to reach the ability stuck-module, improves the purpose of testing precision.
Need to prove that the profile of slip takes place in the time of need milling out soft board 7 bendings on the surface of upper module 311, the distortion with obstruction free soft board 7 influences test effect; The front end semicircle place of lower module cover plate 314 is half bending axle; Bending axle and turning axle 26 are concentric; Therefore lower module cover plate 314 needs very high precision; Need through 2 location PIN and magnet location, upper module cover plate 313 just plays the effect of pushing down the adagio crooked place, therefore only needs through the magnet location just passable.
In the present embodiment, bending anchor clamps 31 have 10 pairs, can test multi-disc soft board 7 simultaneously, have improved testing efficiency significantly.The quantity of bending anchor clamps 31 can be provided with as required, but also cannot be too many, otherwise can increase the resistance that turning axle 26 rotates, influence test effect.
As shown in Figure 2, drive unit 2 comprise servomotor 21, the worm-gear speed reducer 22 that is connected with servomotor 21, active synchronization wheel 23, synchronously with 24, driven synchronizing wheel 25 and the turning axle 26 that is connected with driven synchronizing wheel 25; Active synchronization wheel 23 is connected with worm-gear speed reducer 22, and driven synchronizing wheel 25 is through be with 24 to take turns 23 with active synchronization and be connected synchronously.
Wherein, returning face plate 33 is positioned on the turning axle 26.
Cabinet 1 surface is provided with touch-screen 4, is connected with drive unit 2, and bending angle can be set, bending speed and bending number of times.
Also be provided with light curtain 5 in the cabinet 1, this is a kind of photoelectric protector, when light curtain 5 is blocked; Device can send shielding signals, and machine is quit work, and protection personnel escape injury; Light curtain 5 can certainly be set, and present embodiment is that the angle from safety has increased light curtain safeguard measure.
When making an experiment; Open machine box door 6, soft board 7 is positioned on upper module 311 and the lower module 312 with location PIN through profile pilot hole 315, the position and placed of needs bending is placed the position, boundary of upper module 311 and lower module 312; Then upper module cover plate 313 is pushed down soft board 7; Be positioned on the upper module 311 through magnet, lower module cover plate 314 is pushed down soft board 7, be positioned on the lower module 312 through 2 location PIN and magnet; The intersection of upper module cover plate 313 and lower module cover plate 314 overlaps with the intersection of upper module 311 and lower module 312.Parameters such as bending angle, bending speed and bending number of times, beginning cripping test are set through touch-screen 4 then.
The bending process realizes that through drive unit 2 at first servomotor 21 rotates, and drives worm-gear speed reducer 22 and rotates; Afterwards, active synchronization wheel 23, be with 24 synchronously, driven synchronizing wheel 25, turning axle 26 also rotate successively, returning face plate 33 is along with turning axle 26 is turned to needed angle; The bending part of soft board 7 is close to half bending axle of lower module cover plate 314 and is followed upper module 311 and returning face plate 33 to be turned to the angle of needs, and servomotor 21 counter-rotatings afterwards make returning face plate 33 and upper module 311 get back to original position; Soft board 7 is owing to pushed down by upper module cover plate 313; Also get back to original position, repeat an action then, behind the bending number of times that reaches setting, stop; Off-test is taken out soft board 7 from bending anchor clamps 31.
The bending fatigue testing machine that the utility model provides is made up of cabinet, the drive unit that is positioned at said cabinet and clamp device; Whole device all is in the airtight space; Avoided extraneous interference, helped guaranteeing the accuracy that bends, and make whole device succinctly attractive in appearance.In addition, this bending fatigue testing machine has many secondary bending anchor clamps, can carry out cripping test to the multi-disc soft board simultaneously, has improved testing efficiency significantly; Through touch-screen bending angle, bending speed and bending number of times can be set, can guarantee the precision of testing effectively.
In addition, increase the light curtain in the testing machine, can avoid the generation of security incident effectively, guaranteed operating personnel and other staff's safety; Through location PIN, magnet and screw fixing bending anchor clamps and soft board, can avoid in the test process bending anchor clamps or soft board to be subjected to displacement, cause test inaccurate.
To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the utility model.Multiple modification to these embodiment will be conspicuous concerning those skilled in the art, and defined General Principle can realize under the situation of spirit that does not break away from the utility model or scope in other embodiments among this paper.Therefore, the utility model will can not be restricted to these embodiment shown in this paper, but will meet and principle disclosed herein and features of novelty the wideest corresponding to scope.
