Description
Technical field
The utility model relates to a kind of test unit, relates in particular to flexible flat cable and (is called for short: dielectric voltage withstand test unit FFC).
Background technology
Flexible flat cable Flexible Flat Cable (FFC) is a kind of with PET insulating material and zinc-plated flat copper wire as thin as a wafer; Through the new types of data cable that the pressing of high-tech automation equipment production line forms, have softness, arbitrarily bending fold, thin thickness, volume is little, connections is simple, convenient disassembly, easy solution electromagnetic screen advantages such as (EMI).Must carry out the dielectric test of dielectric voltage withstand aborning, whether the test surfaces membraneous material insulate well, if defective insulation then be substandard product.Existing FFC dielectric detects test method and mainly adopts withstand voltage test; Promptly with compression tester FFC alclad paper tinsel is tested, this method of testing needs special test station, can not be installed in and do synchronism detection on the production line; And once can only test a product; Elapsed time is many, and cost is high, efficient is low, and dangerous.
The utility model content
To above-mentioned defective, the purpose of the utility model is to provide a kind of FFC dielectric voltage withstand test unit, and whether the dielectric voltage withstand that tests out the FFC winding displacement that can be accurate, quick, safe is qualified.
In order to solve the problems of the technologies described above, the utility model is realized through following technical scheme:
A kind of FFC dielectric voltage withstand test unit; Form by console controller and measurement jig two large divisions, it is characterized in that described console controller is made up of power module (1), high-frequency transformer (2), fault wave detector (3), Hi pilot (4), warning system (5) and voltage table (6); Described measurement jig is made up of test electrode (7) and metal detector (8).
Technical scheme further is:
1. described power module (1) links to each other with high-frequency transformer (2), and producing frequency is 2-3.5K Hz alternating current., send the high-frequency transformer primary coil to, make the high-frequency transformer secondary coil produce the 3KV high pressure.
2. described fault wave detector (3) links to each other with high-frequency transformer (2), receives high-frequency transformer primary coil loops Current Control.When the spark of finding the high-voltage output electrode part began to increase, the electric current that flows through oscillatory circuit increased in rain, added a signal will for the fault wave detector.
3. described Hi pilot (4) links to each other with test electrode (7) with high-frequency transformer (2) respectively, receives metal detector (8) control.When metal detector is identified as the metal window notch portion, promptly can controls Hi pilot and break off high pressure, thereby can not accidentally injure the metal window.
4. described warning system (5) links to each other with fault wave detector (3), and controlled by the fault wave detector, produces sound and light alarm.
5. described voltage table (6) links to each other with the secondary coil of high-frequency transformer, indicates high pressure output effective value in real time.
The principle of work of the utility model is such:
FFC surface of insulating layer to be tested is added high pressure through the electrode in the measurement jig; FFC metallic conductor core ground connection; In the time of when metal detector detects the metal window of FFC, will passing through the Hi-pot test electrode, can give signal of Hi pilot, break off high pressure according to the time of setting; When the metal window has passed through to recover high pressure behind the Hi-pot test electrode, thereby avoid the metal window to be broken down by high-voltage.When FFC winding displacement surface insulation layer had defective insulation, high pressure can form the loop through metallic conductor core and ground end, cause one big to vagabond current (leakage current).Circuit can produce one and continue 20 person of outstanding talent's second Weak pulse signals, this signal meeting flip-flop number and actuating of relay, and the fault wave detector triggers failure warning system after detecting this leakage current, sends sound and light alarm, and sends control signal.Thereby the user can detect FFC winding displacement defective insulation point exactly, and whether judge product fine or not.
The beneficial effect of the utility model is and can this test unit be installed on the FFC production line; When defective insulation that breakage, exposed metal/bare metal, impurity, bubble or other reason cause appearred in the FFC insulated part, this test unit can burn vestige by automatic ignition flower generation black, and sends alarm signal; Can find out the part of FFC winding displacement defective insulation fast and accurately; Whether thereby it is qualified to judge the FFC winding displacement, has improved production efficiency greatly, and safety again.

Embodiment
The realization of the utility model has multiple mode, and following preference is for for the public better understands the described technology contents of the utility model, rather than to the restriction of said technology contents.In fact, the increase and decrease to any element, replacement and the improvement in not violating the said invention spirit of the utility model, done are all within the utility model technical scheme required for protection.
The described FFC dielectric voltage withstand of the utility model test unit is realized through following function:
One, as shown in Figure 3, the guidance panel function of the utility model is following:
A. power switch Switching Power Supply.
B. time controller is controlled the time of breaking off high pressure.
C. high-voltage value is tested in the voltage table indication.
D. the high voltage startup button is pressed the high-tension circuit connection, can adjust needed magnitude of voltage.
E. reset key stops to report to the police and recovering outside through transport signal.
F. whether self check button inspection this machine control system and warning performance be normal.
G. reset mode switch optional " manually " and " automatically "." manually ", test product punctures, and goes out continuous sound, light warning, and outside interlock begins action, waits to press " resetting " button and could eliminate.Like choosing " automatically ", test product punctures, and sends sound, light warning, and outside interlock attonity is according to the time of fire alarming of regulating, and sound and light alarm stops automatically.
H. green indicating lamp refers to that safety head builds, and connects by the ground protection.Pilot lamp does not work, and can't start high pressure.
I. the bright expression high pressure of HT pilot pilot lamp starts.
J. puncture pilot lamp and show the bad puncture of test product.
K. voltage regulator contrast voltage table is regulated required trial voltage value.
Count when L. bad counter is tested defective products, a defective products counting once.
