Description
Technical field
The present invention relates to the test of optical device, it particularly relates to the test of LED light source plate.
Background technology
It is well known that the popularization and permanent use with LED illumination lamp prove that Switching Power Supply quality has become certainly
Determine the key factor of LED life.And the manufacturing cost of Switching Power Supply limits the price of LED illumination lamp.Industry starts to abandon out
Powered-down source has become common recognition.Power LED is gone mainly there are two kinds：1. it is extraneous that LED side is driven with linear constant current IC chip
Formula;2. LED modes are driven with CRD.Both of which greatly simplifies the structure of LED lamp, and production procedure is simple, installs letter
Just.But a problem is also brought simultaneously:The problem of how substandard products being measured when light source board is produced in batches.Due to being 220 friendships
LED is lighted in stream civil power direct drive, and current industry not yet has special Hi-pot test instrument.And PCB light source plate can only lean on free-hand
The measures such as coordinated insulation gloves are tested, and bring great personal safety to threaten to tester.
Current industry is tested using card pin type, such as patent《A kind of LED/light source board test device》（Chinese patent
No. 2016209071505）, but card pin type testing jig has the disadvantage that:(1) card pin position immobilizes, regulation inconvenience.And be adapted to
Tested in the contact node of proper alignment, be not suitable for single light source board test.Particularly in the case of substandard products to be repaired, card pin is surveyed
Examination frame is not used completely;(2) card pin testing jig is heavy, is unfavorable for movement;(3) the line of connecting test pin is after permanent flexible test,
It is easily damaged, makes testing jig conductive, bring potential safety hazard.
To solve the problem of existing LED/light source board test is present, people work out《A kind of test machine of LED light source plate》
（Chinese patent application part 201510114626X）, the purpose is to realize LED light source plate brightness detection automation；Also push away afterwards
Go out《A kind of LED/light source board test device》（Chinese patent 2016209071505）, it includes testboard and positioning group
Multiple testing needles are provided with part, testboard, testing needle is connected on controller, testboard by wire and is provided with multiple tests
Pin fixed structure, testing needle is set on testing needle fixed structure at an arbitrary position ....Though above technology can be to LED light source plate
Tested, but these technical schemes have baroque shortcoming, and the power-on switch of device is operated by artificial progress, failed
Realize the Intelligent Adaptive Control of test device.For test point can not flexibly, unrestricted choice, not only cost is high, and makes
With inconvenience.Have no and be born for the special Hi-pot test instrument of LED light source plate so far.
The content of the invention
The present invention is intended to provide one kind removes power supply LED/light source board test pen, to overcome existing LED/light source board test device
Shortcoming so that simplify testing process, improve testing efficiency, especially be ensure tester life safety.
Inventor devises MCU Intelligent control electrics PCB as the Master Control Center of test pen to reach goal of the invention,
Assign its following functions：1. key switch instruction is received, the role of this branch pen is determined --- the output of-selection live wire or zero line are defeated
Go out；2. live wire or zero line input are selected as the output of connection nib according to the Role Dilemma relay system of this branch pen；3. root
According to the capacitance variation of human body sensing shell, human contact's pen is determined whether；When there is human body contact pen, relay system is connected
Zero line or live wire；When human body and penholder depart from, relay system disconnects, a no power.
On this basis, what inventor provided removes power supply LED/light source board test pen, by each one-pen bar in left and right and wire
Composition；Penholder upper bottom has an elliposoidal portion, elliposoidal portion exterior key switch, built-in intelligent control circuit module, intelligence
Control circuit module is connected with wire and key switch respectively；It is human body sensing shell in the middle part of penholder, the shell internal layer is ITO
Glass, outer layer are resistant polyester films, and shell also has wire to connect intelligent control circuit module；Penholder bottom is ambroin bag
The test nib wrapped up in, the testing needle that test nib is made of metal, testing needle one end is in penholder in-core and intelligent control circuit mould
Block is connected, and the other end, which exposes, makees probe.
The circuit of above-mentioned intelligent control circuit module is MCU Intelligent control electric PCBs.
Above-mentioned wire wrapped with insulation, outer layer wraps up a screen layer again, prevents the electric capacity of Hz noise penholder shell
Change.
The internal layer of above-mentioned human body sensing shell is ito glass, and outer layer is resistant polyester film, and internal layer is led with outer layer with ITO
Electrocoat is bonded into one；The ito glass is tin indium oxide (Indium-Tin Oxide) transparent conducting film glass.
The partial-length that above-mentioned test nib exposes is 1mm；Plastic wraps test nib plays a part of fixed nib.
Going the application method and principle of power supply LED/light source board test pen is：The pen of left and right two is used simultaneously, and wire is inserted
Head insertion 220V mains power sockets, grasp penholder and are contacted with contact point, respective key switch is opened, by nib pair
Quasi- contact needs the test point for the LED light source plate tested, and now due to human body electric field, human body is formed with shell inner conductor coating
Inductively electric capacity；Upper and lower ends electric current can flow to contact surface position, and this curent change can have MCU control centres sensor
Detect, MCU judges whether that human body has contact, determines whether nib is powered to judging whether LED light source plate is working properly.
The present invention possesses advantages below：1. small volume, portability is strong, facilitates simple and direct；2. it is safe：Due to being taken off when human body
From pen in a flash, automatically power off, test pen can be put everywhere.In the absence of electric leakage risk；3. power supply high pressure can be greatly improved
LED light source plate production efficiency, improves test speed.Suitable for the test to LED light source plate, also extend to needing 220V to hand over
Flow the energization test of the product of power supply.
