Description

The test unit that twists of planar body
Technical field
The present invention relates to the test unit that twists of the thinner planar body of width and the length (length) with regulation.As such planar body, there are liquid crystal display, organic EL and solar panel etc., also have its width more than the structure of 1m.These planar bodies manufacturing, transport, keeping, construction time bent (twisting), but when being subject to such twisting, be roughly both be not subject to the no-station pole canopy that tensile force is not compressed power yet.Therefore, need to carry out twisting test to check permanance under no-station pole canopy.
Background technology
The applicant proposed as following patent documentation 1 in the past and thread like body test simultaneously under no-station pole canopy such to cable, wirning harness, flexible cord can be twisted and the test unit of distortion (torsion).But, because planar body has quite wide width as described above, so the test twisting and reverse can not be carried out by the way identical with it, more can not carry out simultaneously.
Patent documentation 1: Patent 2011-8649 publication.
Summary of the invention
The invention provides a kind of test unit that twists that the planar body with suitable width and length can be twisted under no-station pole canopy.
Therefore, the invention provides the test unit that twists of the planar body described in a kind of technical scheme 1, it is characterized in that, make from the axis of swing of the equidirectional swing of two side direction of column as with one heart and inwardly projecting, arm is fixed on upward on axis of swing, the front end of arm is installed the stationary clamp fixing by the top of test body will be made up of planar body, and axle supporting the bracket of two rollers of rotation can be made the mid point in the axle center of roller and the axle center of driving shaft concentric and is fixed on the inner side of arm, make by test body by between two rollers to downward-extension, lower end is attached to and is exerted a force downwards by spring or deadweight and on the movable clamp that declines, the inner side of this external bracket, will be maintained by test body by the outside of test body tension-free tension force absorb rope by roller between be attached on stationary clamp and movable clamp.
In addition, the present invention twists in test unit at above, and providing the tension force described in technical scheme 2 to absorb rope, to absorb rope at the means being provided with two by the both sides of test body and the tension force described in technical scheme 3 be rope that rigidity is higher, its fineness degree means roughly the same with the thickness of planar body.
If clamp by the stationary clamp of test body with the top be connected with arm, make arm swing and roll up with two roll bendings, then planar body is wound up on roller, and correspondingly girth is elongated compared with time straight.Now, because the interval of the mid point (axis of swing) of stationary clamp and roller is certain, so the length of roller and movable clamp shortens slightly, if correspondingly movable clamp does not rise, then no-station pole canopy can not be remained by by test body.What can realize this effect is that tension force absorbs rope, is risen by movable clamp tractive and will be remained no-station pole canopy by test body.On the other hand, if arm to directly over return and become by test body straight, then contrary to the above, if movable clamp is not declined downwards, test body is occurred lax.
So, now movable clamp is by spring (also can be deadweight) tractive downwards, but movable clamp absorbs rope by tension force only drops to the position (will be remained tension-free position by test body) of regulation, no matter so how the angle that swung by test body of result and speed are all retained as no-station pole canopy.According to the means of technical scheme 2, even there is the test body of width, also can remain no-station pole canopy over the entire width, according to the means of technical scheme 3, when making to be twisted by test body with roller, in girth, there is no difference, more strictly can remain no-station pole canopy.

Embodiment
Hereinafter, with reference to the accompanying drawings of embodiments of the present invention.Fig. 1 is the front view of the test unit that twists representing an example of the present invention, Fig. 2 is the A-A cut-open view of Fig. 1, Fig. 3 represents the cross-sectional view by the relation of test body and roller, this testing machine by the column 1 as framework, two arms 2 extended upward in the inner side of column, to be located on the front end of arm 2, using as planar body the stationary clamp 4 fixed by the upper end of test body 3 and can be located at up and down column 1 both sides, the movable clamp 5 etc. clamped by the lower end of test body 3 is formed.
Wherein, arm 2 is fixed on bracket 6 by welding or bolted etc., and an arm 2 can be swung by the axis of swing 8 driven from drive unit 7.Another arm 2 is also synchronized with an arm 2 and swings, and therefore, in column 1, passes to another arm 2 by the drive structure 10 of miter gear 9 grade.On bracket 6, on the position separated before and after axis of swing 8, from being rotatably provided with pair of rolls 11, can insert by test body 3 with surplus to a certain degree between this roller 11 at predetermined intervals.
Stationary clamp 4, movable clamp 5 are all the parts will clamped by test body 3, such as, above fixed by screw fastening or folder.Movable clamp 5 wherein can relative to column about 1.Further, on stationary clamp 4 and movable clamp 5, by the both sides of test body 3 by roller 11 between to be provided with two tension force and to absorb rope (hereinafter referred to as rope) 12.When making arm 2 swing, making between stationary clamp 4 and movable clamp 5 constant, will be maintained no-station pole canopy by test body 3, in this, the length setting of rope 12 is remain length corresponding to tension-free length with by by test body 3.
On the other hand, foregoing describe movable clamp 5 can move up and down, but in the present invention, rope 12 is attached on movable clamp 5, and is always used by the bracket 18 of supporting movable clamp 5 spring (diagram is omitted) exert a force and can slide up and down relative to column 1 (also can be due to deadweight) downwards.In addition, move up and down (particularly the moving downward) of movable clamp 4 must move rapidly, so this spring is spring stronger in a way when to twist at a high speed.In addition, rope 12 ropes that preferably rigidity is higher, need two all identical.
Fig. 4 is used to the key diagram of the drive unit 7 that axis of swing 8 is swung, but making axis of swing 8 swing is that what kind of structure can, if such as above axis of swing 8 (or below) arrange be forced to rotate plectane 13, cam follower 14 is installed on plectane 13, cam follower 14 and axis of swing 8 connector 15 is linked, then by the certain orientation rotation of plectane 13, axis of swing 8 is swung.Now, the rotation of plectane 13 must be corresponded to and change the position of cam follower 14 relative to connector 15, as long as but to form the elongated hole 16 of the position of adjustment cam driven member 14 on connector 15 just passable.In addition, if the groove inserted by cam follower 14 makes elongated hole 17 diametrically, then pendulum angle can be changed.
Fig. 5 be represent by stationary clamp 4 and movable clamp 5 carry out by the cut-open view of an example of the state of the clamping of test body 3, consider casing 4a, the 5a of the U-shaped body forming center side opening respectively, insert by test body 3 among this casing 4a, 5a, tighten from clamping elements 19 such as the one side bolts of casing 4a, 5a and the structure that clamps.In the case, in order to not injure by test body 3, preferably on two sides, the bolster such as soft resin or rubber 20 is sticked.In addition, also can consider to press from both sides upper such structure by by whole of test body 3 as the clothes washing clamp of brute force.
Then, to being described by the test that twists of test body 3 as planar body, what stationary clamp 4 and movable clamp 5 clamp by test body 3 is upper and lower, plectane 13 is rotated, makes axis of swing 8 swing rotary.So arm 2 and bracket 6 swing, and stationary clamp 4 also swings, and are sought its long duration test by test body 3 by repeatedly twisting to the left and right thereupon, during this period, by restrict 12 existence, no-station pole canopy will be remained by test body 3.That is, if twisted, then movable clamp 5 by rope 12 upward tractive rise, if become straight, then movable clamp 5 is declined downwards by spring tractive, but does not drop to more than the length of rope 12.In this, rope 12 also plays the effect that the decline of restriction movable clamp 5 needs above retainer.Certainly, the number of times repeatedly swung is counted.
In addition, roller 11 can rotation, but also can form the less arm axle 11a of diameter at its two ends, be used the rotatable ground axle suspension of bracket 6, also arm axle 11a can be fixed on bracket 6, by among arm axle 11a break-through to roller 11, by roller 11 bearing etc. and support thereon.In addition, when wanting to change the position twisted, making it possible to the position of stationary clamp 4 to change relative to arm 2, can realize by changing this position.In addition, also can replace the spring of the movable crank 5 of tractive and make weight.
