Description
Technical field
The present invention relates to a kind of LED lamp bar ageing tester, particularly relate to a kind of LED hard lamp bar ageing tester,
Belong to LED lamp bar technical field of measurement and test.
Background technology
LED hard lamp bar is to do assembling wiring board with PCB hardboard, and the useful paster LED of LED carries out assembling, the most useful straight cutting
LED carries out assembling, optionally different and use different elements.
Along with the development of society, LED hard lamp bar is due to its environmental protection, and energy consumption is low, and luminous intensity is big, and shock resistance is good
Being widely used in various field etc. advantage, by high temperature ageing 1000 hours in 80 DEG C of high-temperature cabinets, the test of not dead lamp is tested
Card, reliability of service life requirement when being that LED lamp bar is applied to LCD TV design or before batch production, therefore LED lamp bar
Burn-in test essential.And existing LED lamp bar ageing tester to there is heating uneven, LED lamp bar is heated inequality
Even problem, also has, and LED lamp bar explosion phenomenon the most easily occurs in LED lamp bar ageing tester, and existing
LED lamp bar ageing tester is without explosion prevention function, poor stability.
Summary of the invention
The technical problem to be solved is to provide a kind of rotatable, and LED lamp bar is heated evenly, and has
Have from decompression function, have explosion-proof effect, the LED lamp bar ageing tester that safety coefficient is high.
For solving above-mentioned technical problem, the technical solution used in the present invention is:
A kind of LED lamp bar ageing tester, including casing, is provided with pallet, under described pallet in described casing
End is connected with rotating shaft, and described rotating shaft is connected with electric rotating machine after passing described tank floor, described pallet is provided with some
For fixing the fixture of LED lamp bar, described fixture includes the airtight empty van being arranged on described pallet, described airtight empty van
Upper surface be provided with the upper through hole contacted with described LED lamp bar, the lower surface of described airtight empty van is provided with and flexible pipe phase
Lower through-hole even, whole described flexible pipes are all connected with total flexible pipe, and described total flexible pipe is connected with vacuum pump；The inwall of described casing
In be provided with and add heat pipe；Described casing top is provided with relief valve.
The described heat pipe that adds is connected with attemperating unit.
Described upper through hole is all connected with described airtight empty van with lower through-hole.
Described airtight empty van is square, and the length of side of described airtight empty van is less than the width of described LED lamp bar.
It is cased with bearing outside described rotating shaft, between described bearing and described tank floor, is provided with sealing ring.
Described sealing ring includes metal o-ring.
Beneficial effects of the present invention: the present invention provide a kind of LED lamp bar ageing tester, pallet, rotating shaft and
The setting of electric rotating machine, enables LED lamp bar to be tested to rotate, therefore LED lamp bar to be tested is heated evenly, and test result is accurate；
Airtight empty van, flexible pipe, total flexible pipe and the setting of vacuum pump, for the fixture of LED lamp bar to be tested, the most to be tested for vac sorb
LED lamp bar, prevents LED lamp bar to be tested to be subjected to displacement under the effect rotated, therefore the present invention can carry out the same of multiple LED lamp bar
Time test, and vac sorb mode action temperature and, LED lamp bar to be tested will not be damaged；Airtight empty van is square, confined air
The length of side of case, less than the setting of the width of LED lamp bar, makes the heating surface (area) (HS of LED lamp bar to be tested realize maximizing, makes test tie
Accurately, LED lamp bar to be tested is put in airtight empty van upper surface to fruit, and LED lamp bar to be tested is little with the contact surface of airtight empty van,
Making LED lamp bar to be tested lie substantially in vacant state, LED lamp bar heating surface area to be tested is big.
