Movable holddown in metal guide rail.This process is the supply line's arrangement for completing flexible LED lamp filament test device.
As preferred technical scheme, described fixation briquetting is made up of tabletting, rotating bar, spring and dielectric support block,
Tabletting is that insulating materials making, rotating bar, spring are conductive material.Rotating bar is through tabletting inside and is fixed on insulating supporting
On block.Spring is arranged on one side of tabletting, when one side to tabletting applies pressure, is going to the supporting role lower sheeting of bar
In addition while can be lifted, when application pressure is removed, tabletting can be promptly restored to the state compressed.Described activity pressure
Block is arranged in metal guide rail to be made up of bearing, insulation tabletting, rotating bar, spring and metal support block, the tabletting of movable holddown,
Rotating bar, the construction of spring metal support block are as fixed briquetting, and difference is that movable slider is provided with bearing, and passes through axle
Holding can be in metal guide rail slidably.The purpose of fixed briquetting and movable holddown is for the metal of compression flexible LED filament
Terminal, powers to flexible LED filament, while under the movement of movable holddown, distorting flexible LED filament.
As preferred technical scheme, described test device pedestal, supporting plate, test body panel, metal guide rail are fixed
Block is made using insulating materials.
As preferred technical scheme, described test body panel middle part is hollow out, void region and supporting plate, is surveyed
The space in examination body panel besieged city provides space for the distortion test of flexible LED filament.
The beneficial effect of the embodiment of the present invention is：
1st, power circuit respectively leads to fix briquetting end and movable holddown end by test device base, supporting plate.Work as flexible LED
Two metal electrode terminals of filament be pressed in fixed briquetting and movable holddown it is upper when, it can be flexible LED to switch on power
Filament, which is powered, lights flexible LED lamp silk.
2nd, due to being provided with bearing in movable holddown, and it is arranged in metal guide rail, movable holddown can very easily again
Slided in metal guide rail.The beneficial effect of this point is to maintain the illuminating state of flexible LED filament, flexible LED filament is followed work
Dynamic pressure block is slided and distorted together, with test inside filament whether with the presence of failure welding chip.
3rd, because movable holddown can slidably reciprocate, flexible LED filament both can be lighted test with straight, can distort again
Light test.
4th, the present invention is simple in construction, easy to operate, and because tabletting has certain width, therefore the test device of the present invention can
Simultaneously clamped on a plurality of flexible LED filament and light test, overcome at present can only wall scroll the drawbacks of light test, improve test
The efficiency of technique, reduces unnecessary human cost expenditure.
