Abstract

The utility model provides a device for testing the LED polarity with ICT in a batch manner. A test needle bed is fixed to the upper part of a base of the structure thereof; the upper part of the test needle bed is provided with two sets of test probes which are arranged symmetrically and PCB support pillars; the four corner ends of each set of test needles are provided with the PCB support pillars; the lower part of the test needles are connected with a controller arranged in the test needle bed by wires; columns are fixed at both ends of the base respectively; rails are fixed on the top ends of the columns and connected with a lifting pressure board arranged on the lower part thereof by a telescopic connecting rod. The device for testing the LED polarity with ICT in a batch manner is characterized by reasonable design, simple structure, convenient use and the like; for a large quantity of LCDs arranged on a common PCB, only two test points needed to be arranged and a row of or a line of LEDs can be detected by the arranged test points; the test speed is faster and only 0.01 second is needed to detect one LED; therefore, the device for testing the LED polarity with ICT in a batch manner has good use value.

Description

A kind of with ICT batch testing LED polarity device

1, technical field

The utility model relates to a kind of LED proving installation, and is specifically a kind of with ICT batch testing LED polarity device.

2, background technology

Continuous progress along with society, the use of LED is more and more universal, because the phenomenon that exists LED polarity to put back in the production run, after being assembled into finished product, the fault that LED does not work can appear, but be fit to now the device that LED detects, the mode of manual detection can only be selected by many enterprises, and to have the efficient of great injury but also its detection for the eyes that detect the workman very low and this mode detects not only.

Its glow color of LED luminotron can be divided into multiple colors such as redness, orange, green, blue light, different chips need be installed when detecting make LED send different colors to carry out complete detection, and use non-professional LED proving installation just to detect inconvenience very.

3, summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of with ICT batch testing LED polarity device, can realize fast and accurately testing goal automatically.

The technical solution of the utility model realizes in the following manner, its structure is made of base, test needle-bar, controller, testing needle, pcb board support column, column, cross bar, lifting pressing plate, shrinking connecting-rod and lead, the top of base is fixed with the test needle-bar, the top of test needle-bar is provided with two groups of symmetrically arranged testing needles and pcb board support column, four jiaos of ends of every group of testing needle are provided with the pcb board support column, the lower end of testing needle by lead be arranged on the controller of test in the needle-bar and be connected; The two ends of base are fixed with column, and the top of column is fixed with cross bar, and cross bar is connected by shrinking connecting-rod with the lifting pressing plate that its underpart is provided with.

The sidewall of above-mentioned base is provided with control handle and pilot lamp.

Four jiaos of ends of above-mentioned lifting pressing plate are provided with support column.

The utility model has the advantages that:

Of the present utility model a kind of with ICT batch testing LED polarity device, have characteristics such as reasonable in design, simple in structure, easy to use, for a large amount of LED that are provided with on the common pcb board, 2 test points only need be set detect a delegation or a row LED, its detection speed is very fast, detect a LED and only need 0.01 second time, thereby have good use value.

Mark in the accompanying drawing is represented respectively; 1, base; 2, test needle-bar; 3, controller; 4, testing needle; 5, pcb board support column; 6, pcb board; 7, control handle; 8, pilot lamp; 9, column; 10, cross bar; 11, lifting pressing plate; 12, support column; 13, shrinking connecting-rod; 14, lead.

5, embodiment

Below in conjunction with accompanying drawing 1-2 a kind of ICT of using batch testing LED polarity device of the present utility model is done following detailed description the in detail.

Shown in accompanying drawing 1-2, of the present utility modelly a kind ofly constitute by base 1, test needle-bar 2, controller 3, testing needle 4, pcb board support column 5, column 9, cross bar 10, lifting pressing plate 11, shrinking connecting-rod 13 and lead 14 with its structure of ICT batch testing LED polarity device, the top of base 1 is fixed with test needle-bar 2, the top of test needle-bar 2 is provided with two groups of symmetrically arranged testing needles 4 and pcb board support column 5, four jiaos of ends of every group of testing needle 4 are provided with pcb board support column 5, and the lower end of testing needle 4 is connected with controller 3 in being arranged on test needle-bar 2 by lead 14; The two ends of base 1 are fixed with column 9, and the top of column 9 is fixed with cross bar 10, and cross bar 10 is connected by shrinking connecting-rod 13 with the lifting pressing plate 11 that its underpart is provided with.

The sidewall of base 1 is provided with control handle 7 and pilot lamp 8.

Four jiaos of ends of lifting pressing plate 11 are provided with support column 12.

Controller 3 can be regulated control LED and show multiple color.

During use, at first open control handle 7, then pcb board 6 is placed on the pcb board support column 5 on the test needle-bar 2, lifting pressing plate 11 is pressed in pcb board 6 on the testing needle 4, though LED is more on the pcb board 6, it is provided with all is that matrix form is arranged, and therefore only needs 2 test points on the test pcb board 6 can detect a delegation or a row LED, test speed is very fast, and detecting a LED only needs 0.01 second time.

Decision method be resistance when low LED polarity correct, LED incorrect polarity when resistance is high.

Of the present utility model a kind of very simple and convenient with its processing and fabricating of ICT batch testing LED polarity device, can process shown in the accompanying drawing to specifications.

Except that the described technical characterictic of instructions, be the known technology of those skilled in the art.
