Embodiment
Fig. 1 is the modular structure figure of the safety testing apparatus of an embodiment.This safety testing apparatus 10 is used for test board is tested automatically, comprises automatic transmission system 100 and test macro 200.Automatic transmission system 100 automatically transmits described test board one by one, navigates to test position and docks with test macro 200, and 200 pairs of test boards that arrive described test position of test macro are tested.
Test board automatically transmits, locates by automatic transmission system 100 and docks with test macro 200, is then tested by test macro 200, thereby can automatically finish the test of test board, reduces manually participating in, thereby improves testing efficiency and security.
In a specific embodiment, please refer to Fig. 2, this safety testing apparatus 10 also comprises the support body 900 of the above-mentioned automatic transmission system 100 of carrying and test macro 200.Fig. 2 is the structural representation of safety testing apparatus 10, and it roughly reflects relative position relation and configuration relation between the parts, and is not understood to the diagram of practical structures.
Connecting gear 110 is positioned at the upper surface of support body 900, is used for the horizontal transmission test board.Connecting gear 110 comprises transmission drawstring 111 and drawstring motor 112.Drawstring motor 112 drives and transmits drawstring 111 operations, to transport described test board to test position.Drawstring motor 112 is electrically connected with transfer control 140, and started by transfer control 140 control or close.The form that is appreciated that connecting gear 110 is not limited to transmission drawstring 111 and the drawstring motor 112 that the present embodiment provides, and also can be other forms.
Whether detecting device 121 also docks to put in place for detection of actuating cylinder 131 is put in place with separating, and put in place or separate in actuating cylinder 131 docking and send stop signal when putting in place, transfer control 140 according to the stop signal shut electromagnetic valve so that actuating cylinder 131 stops action.Docking is put in place and separates the detection that puts in place and can guarantee to test needle-bar 210 and stop in place.
Further, automatic transmission system 100 also comprises on the transfer path that is arranged at connecting gear 110, is used for preventing the dorsad anti-mechanism 150 that puts back of test macro placement of one side that test board docks with test macro 200.
Further, automatic transmission system 100 also comprises the anti-stacking mechanism 160 that prevents the overlapping placement of a plurality of test boards.Anti-stacking mechanism 160 comprise stack detector switch (figure indicates), be subjected to the described anti-control circuit 162(that stacks of detector switch control that stacks with reference to figure 3) and by the anti-retention device 163 that stacks control circuit 162 controls.Whether stack detector switch and be arranged at the test position place, detecting has test board to enter.Retention device 163 is arranged on the transfer path of test board, when having test board to test, next test board is blocked in outside the test position.Stack detector switch and can select light-operated switch, retention device 163 is preferably the adjustable end stop of cylinder control.
As shown in Figure 3, be the anti-circuit theory diagrams that stack control circuit in the safety testing apparatus shown in Figure 2.The anti-control circuit 162 that stacks comprises optoelectronic switch U1, NPN type triode Q1, positive-negative-positive triode Q2 and a plurality of resistance that are used for the dividing potential drop current limliting, also comprises the relay K 1 that is subjected to NPN type triode Q1 control.Whether optoelectronic switch U1 detects test board and arrives, when test board arrives, the output terminal conducting of optoelectronic switch U1, the base stage of positive-negative-positive triode Q2 is high level, positive-negative-positive triode Q2 conducting, NPN type triode Q1 base stage is low level then, and conducting that the coil of relay K 1 is got is electric, the normally opened contact adhesive, the normally closed contact and the power supply that are connected with the solenoid valve of control cylinder action disconnect.The uncontrollable adjustable end stop of cylinder rises, and blocks the passage that transports of test board.On the contrary, if there is not test board to arrive, optoelectronic switch U1 then can control adjustable end stop and rise, and opens and transports passage.
As shown in Figure 4, be the circuit part schematic diagram of tester in the safety testing apparatus of an embodiment.The circuit part of tester 220 comprises main control chip LM324, the abnormality processing module 221 that is connected with main control chip LM324 the second output pin and the normal process module 223 that is connected with main control chip LM324 the 3rd output pin.Abnormality processing module 221 resets tester 220 and the unusual test board of mark according to the received test abnormal signals of tester 220, and normal process module 223 is according to the received test normal signal output switching signal of tester 220.
When tester 220 output FAIL level, 7 pin of LM324 (i.e. the second output pin) output high level, thereby trigger the relay adhesive of two parallel connections, the output switching signal of time-delay resets to tester 220, utilize this time of time-delay, another relay adhesive triggers bad sign cylinder action and stamps error identification at test board.When tester 220 output PASS level, 8 pin of LM324 (i.e. the 3rd output pin) output high level, triggering Q1 with the relay adhesive, output switching signal.
The above embodiment has only expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
