The < first embodiment > of phone housing buckling deformation automatic checkout system
In the first embodiment of the utility model phone housing buckling deformation automatic checkout system, Fig. 1 a and Fig. 1 b show detection faces 2, phone housing 3, bar shaped detection light source 4, detection track 5, photoresistance 6, sliding shoe 7 and the bar-shaped trough 8 of detection platform 1, level.
The shape of detection platform 1 can be rectangular parallelepiped, and it has the detection faces 2 of level.Detection faces 2 answers no concave-convex to rise and fall, to guarantee can, because of the concavo-convex formation gap of detection faces 2, not guarantee the degree of accuracy detecting between phone housing 3 and detection faces 2.
As shown in Figure 1 b, 4 bar shaped detection light source 4 in detection faces 2, have been fixed.
As shown in Figure 1a, after phone housing 3 is placed in detection faces 2, open bar shaped detection light source 4, bar shaped detection light source 4 sends to the edge of detection faces 2 light beam that is parallel to detection faces 2, and light beam is towards phone housing 3, and is parallel to the light beam of detection faces 2.
Surrounding in detection platform 1 is also fixed with 4 detection tracks 5.Each detects on track 5 and is provided with bar-shaped trough 8, and photoresistance 6 is fixed on sliding shoe 7, and sliding shoe 7 is arranged on bar-shaped trough 8 movably.By sliding shoe 7, photoresistance 6 can freely be adjusted position along the length direction of bar-shaped trough 8 on detection track 5.The quantity of the photoresistance 6 on each detection track 5 is adjustable, should be according to actual conditions setting.Can understand, also can remove and detect track 5, directly sliding shoe 7 is fixed on base plate 23.
During detection, first phone housing 3 is positioned in detection faces 2, and completely 4 bar shaped detection light source 4 is shrouded in phone housing 3, then open bar shaped detection light source 4.When there is buckling deformation in phone housing 3, can generation gap between phone housing 3 and detection faces 2, buckling deformation is larger, and gap is larger, and the suffered light leak amount of photoresistance 6 is more.It is corresponding with it that each photoresistance 6 has detecting unit.When the light leak amount being subject to arrives when a certain amount of, detecting unit is judged as substandard product, gives the alarm.
Detecting unit as shown in Figure 2, comprises light quantity measurement module 6a, base modules 6b, comparison module 6c and alarm modules 6d.Wherein, light quantity measurement module 6a comprises photoresistance 6 and the divider resistance R2 thereof being connected in series, and for measuring light leak amount, and the measuring voltage value corresponding with measuring light leak amount is sent to comparison module; Base modules 6b comprises adjustable reference resistance R3 and the divider resistance R4 thereof of size being connected in series, and for setting reference voltage value, and reference voltage value is sent to comparison module; Comparison module 6c is comparer U1, and for comparing and measuring magnitude of voltage and reference voltage value, when measuring voltage value is less than reference voltage value, comparison module output high level, detects phone housing and be out of shape; Alarm modules 6d comprises the first divider resistance R5, the second divider resistance R6 and the 3rd divider resistance R7, and relay K 1, diode and triode Q1, for receiving the signal being sent by comparison module, and gives the alarm.
When detecting unit detects, take photoresistance 6 as sensor, utilize the resistance of photoresistance 6 and principle that the quantity of illumination is inversely proportional to carry out the light leak amount of detection of handset shell 3, then differentiate the gap length between phone housing 3 and detection faces 2 by comparer U1.When the buckling deformation of phone housing 3 becomes large, light leak amount increases, and the light quantity being subject to along with photoresistance 6 increases, and its resistance value reduces, and the A point voltage in the bleeder circuit that photoresistance 6 and divider resistance R2 thereof form reduces.Comparer U1 compares A point voltage and reference voltage, and the voltage that between reference resistance R3 and divider resistance R4 thereof, B is ordered compare, when A point voltage value is reduced to B point voltage value when following, comparer U1 exports high level, by triode Q1 amplifying circuit, drive relay K 1 action, with the defective signal of output products, light emitting diode is lighted simultaneously.When the buckling deformation amount of phone housing 3 reduces, light leak amount weakens, and the resistance value of photoresistance 6 raises, and A point voltage raises.When A point voltage is during higher than B point voltage, comparer U1 output low level, triode Q1 cut-off, relay K 1 power-off simultaneously light emitting diode turn off the light.
In actual design, can adopt the adjustable reference resistance R3 of resistance, by adjusting the resistance of reference resistance R3, adjust the reference voltage that B is ordered.
When initial, the voltage that A is ordered can be greater than the voltage that B is ordered, and also can equal the voltage that B is ordered.
Alarm modules 6d in detecting unit also can remove, and only needs comparison module 6c to obtain can learning that whether phone housing 3 is qualified after comparative result.
The testing result of a detecting unit has embodied phone housing 3 certain local deformation.In actual applications, can a plurality of photoresistance 6 be installed on a detection track 5, a plurality of detecting units are set, for detection of a plurality of positions of phone housing 3, improve the degree of accuracy detecting.When adopting a plurality of above-mentioned photoresistance 6, the relay node of a plurality of photoresistance 6 corresponding detecting units is carried out to parallel connection output, control hummer, as shown in Figure 3, when having, any one check point is abnormal, and hummer will pipe.
When phone housing 3 is not placed in detection faces 2, the light that bar shaped detection light source 4 is sent will shine directly in photoresistance 6, thereby export and give the alarm.Therefore, need to control the switch of bar shaped detection light source 4, only to guarantee that, when phone housing 3 is placed in detection faces 2, bar shaped detection light source 4 is just opened.In application, can increase photoelectric sensor and whether be placed in detection faces 2 with detection of handset shell 3, if be placed in detection faces 2, output signal, control bar shaped detection light source 4 and open, if photoelectric sensor does not detect phone housing 3, control bar shaped detection light source 4 and close.
