Abstract
The invention relates to a rapid and reliable flat cable assembly detection device which is used for detecting positive and negative design of light emitting diodes through adjacent flat cables and solving the problem of short circuit detection. A complementary design is adopted in short circuit detection circuits at two ends of a flat cable, i.e., the anode of the light emitting diode at one end is connected with a dual-row socket, and the cathode of the light emitting diode at the other end is connected with a dual-row socket. By means of the structures of the short circuit detection circuits, the open circuit detection of a light emitting diode stack is realized, the detection is rapid and convenient as well as accurate and reliable to ensure that the degree of automation in operation of the detection device is greatly improved; and a flat cable assembly checked by using the detection device has greatly improved quality and reliability and working efficiency increased by tens to hundreds of times.

Embodiment
A kind of rapid and reliable flat-cable assembly pick-up unit; It comprises the double Plug pin patch bay of the double Plug pin patch bay of power supply 1, first diode 2, second diode 3, first 9, first flat-cable assembly 10, second flat-cable assembly 17, second 18, light emitting diode, cable; First diode 2 is connected with power supply 1, and second diode 3 of two series connection is connected with first diode 2, being connected with the first double Plug pin patch bay 9 of first flat-cable assembly 10; Light emitting diode is connected with the first double Plug pin patch bay 9; The anode of first light emitting diode of said light emitting diode connects power supply 1, and negative electrode is connected with the first double Plug pin patch bay 9, and the anode of adjacent with it light emitting diode is connected with the first double Plug pin patch bay 9; Plus earth, other light emitting diode is with this series arrangement; Second flat-cable assembly 17 is connected with the second double Plug pin patch bay 18; Light emitting diode is connected with the second double Plug pin patch bay 18; The anode of first light emitting diode of said light emitting diode is connected with the second double Plug pin patch bay 18, plus earth, and the negative electrode of adjacent with it light emitting diode is connected with the second double Plug pin patch bay 18; Anode connects power supply, and other light emitting diode is with this series arrangement; First flat-cable assembly 10 is connected through cable with second flat-cable assembly 17.Described flat-cable assembly is 16 cores.
As shown in Figure 1; Flat cable pick-up unit 5V power input 1; At first carry out overvoltage protection, be unlikely to burn out the light emitting diode in the testing circuit, again through two series connection second diodes 3 through transient state suppressing first diode 2; Carry out level conversion and anti-reverse processing, obtain 3.6V voltage VCC.
The head end short-circuit detecting: the first flat-cable assembly head end 10 at first is inserted on the first double Plug pin patch bay 9, on principle design, the anode of first light emitting diode 8 is connect power supply; Negative electrode docks with double Plug pin patch bay 9, and the anode of adjacent with it light emitting diode 7 docks plus earth with double Plug pin patch bay 9; Other light emitting diode is with this series arrangement, if adjacent cable 11,12, short circuit between 13 just makes adjacent light emitting diode 6,8 or optical diode 7,8 formation loops through short dot; Light the diode connection; The pressure drop that single light emitting diode bears is 1.8V, and brightness is moderate, if there is not short circuit between the adjacent cable; Can not form the loop between the diode 7 and 6 or 8, therefore all do not work.
The tail end short-circuit detecting: the second flat-cable assembly tail end 17 is inserted on the second double Plug pin patch bay 18, and the arrangement of light emitting diode and head end are just in time opposite on principle design, and the anode of first light emitting diode 14 docks with double Plug pin patch bay 18; Plus earth, the negative electrode of adjacent with it light emitting diode 15 docks with double Plug pin patch bay 18, and anode connects power supply; If there is short circuit in adjacent cable 11,12,13; Just make adjacent light emitting diode 14,15 or 15,16 formation loops, connect diode and light, if there is not short circuit between the adjacent cable through short dot; Diode 14,15 or 15,16 can not form the loop, does not therefore all work.
