The checkout gear of a kind of mobile phone locking key and side switch
Technical field
The utility model relates to a kind of checkout gear of mobile phone component, particularly the checkout gear of a kind of mobile phone locking key and side switch.
Background technology
In the parts of mobile phone products, usually need to install locking key and two parts of side switch of mobile phone, there is depressible bimetallic strip locking key and side switch inside, when hand is pressed mobile phone locking key and side switch, bimetallic strip is contacted, locking key and the effect of side switch competence exertion, when if locking key and side switch phenomenon of rupture occurs or other fouling product are arranged, locking key is connected bimetallic strip and then can not be normally connected with side switch, show as locking key and side switch failure state, for bad locking key and side switch are in time chosen, originally adopt and manually test with universal instrument, but when testing with universal instrument, namely need to press locking key and side switch with hand, need again to test with the manual manipulation universal instrument, so testing efficiency is low, test result is also made mistakes easily.
Summary of the invention
Be the low problem of efficient that solves hand picking, the checkout gear of a kind of mobile phone locking key and side switch now is provided, concrete technical scheme is, the checkout gear of a kind of mobile phone locking key and side switch, comprise casing, display screen, voltage regulating meter, buzzer, Air-regulating valves, base clamp, near inductor, the PLC controller, electromagnetically operated valve, cylinder, grating, oil water separator, pressure head, the locking key cylinder, side switch cylinder and scram button, it is characterized in that: be divided in the casing, lower two-layer, the PLC controller is installed on the upper strata, electromagnetically operated valve and cylinder, the lower floor top is installed pressure head and is linked together with cylinder piston, lower floor's bottom mounting seat anchor clamps, near inductor, locking key cylinder and side switch cylinder, and make base clamp and pressure head on same central vertical axis, the front outer surface of casing is equipped with display screen, voltage regulating meter, Air-regulating valves and scram button, casing one side external surface is equipped with buzzer and oil water separator, two side external surfaces are equipped with grating near the front surface opening part; Its electricity, gas circuit are linked as the PLC controller respectively with display screen, Air-regulating valves, link together near inductor, electromagnetically operated valve input and grating, the electromagnetically operated valve output links together with cylinder, locking key cylinder, side switch cylinder respectively, and oil water separator and cylinder gas circuit link together.
Beneficial effect is that checkout gear adopts pneumatic operation to improve stable testing degree and testing efficiency, uses grating and tests the fail safe that control has improved test operation, and locking key and side switch are tested simultaneously, have saved manpower, have improved testing efficiency.

Embodiment
Such as Fig. 1,2, shown in 3, be divided in the casing 1, lower two-layer, PLC controller 8 is installed on the upper strata, electromagnetically operated valve 9 and cylinder 10, the lower floor top is installed pressure head 13 and is linked together with cylinder 10 pistons, lower floor's bottom mounting seat anchor clamps 6, near inductor 7, locking key cylinder 14 and side switch cylinder 15, and make base clamp 6 and pressure head 13 on same central vertical axis, the front outer surface of casing 1 is equipped with display screen 2, voltage regulating meter 3, Air-regulating valves 5 and scram button 16, casing 1 one side external surfaces are equipped with buzzer 4 and oil water separator 12, two side external surfaces are equipped with grating 11 near the front surface opening part; Its electricity, gas circuit are linked as PLC controller 8 respectively with display screen 2, Air-regulating valves 5, link together near inductor 7, electromagnetically operated valve 9 inputs and grating 11, electromagnetically operated valve 9 outputs link together with cylinder 10, locking key cylinder 14, side switch cylinder 15 respectively, and oil water separator 12 links together with cylinder 10 gas circuits.
Before test products, utilize first Air-regulating valves 5 to debug the force value of test machine action identical with the required force value of side switch with locking key with voltage regulating meter 3, staff is placed on test product on the base clamp 6, have near the base clamp 6 near inductor 7, when having sensed product near inductor 7 and put into, can send 8 one signals of PLC controller of box house near inductor 7, grating 11 also can be given respectively 8 one signals of PLC controller after staff is put into and left simultaneously, when PLC controller 8 detects the signal that leaves near inductor 7 and grating 11 staff, PLC controller 8 is controlled by 9 pairs of cylinders 10 of electromagnetically operated valve, make it will utilize the gas of from oil water separator 12, coming in that pressure head 13 is depressed and fasten product, simultaneously, PLC controller 8 is tested by side switch and the locking key of die pressing product by electromagnetically operated valve 9 control locking key cylinders 14 and side switch cylinder 15 simulation staff, test result can show at display screen 2, when measuring product when bad, buzzer 4 can be sounded a buzzer and be pointed out, and can press scram button 16 when abnormal conditions occurring in the test process machine is stopped.
