Description
Technical field
The utility model relates to a kind of automatic assembling apparatus, particularly a kind of key durance test device for feeding back with button.
Background technology
No matter be any product, if it has button, all need to carry out button durable test to detect the demand whether button meets client in the production phase.In existing test equipment for push button durability, most of proving installation all just carries out record to the number of times sent by signal, and records the number of times as pushing button using this, detects the situation of tested button after completing repeatedly test again.Whether the impact of cylinder and the button of product are not pressed in this process and do an effective feedback action, have potential impact to durable test.
Summary of the invention
The purpose of this utility model is the defect in order to overcome above-mentioned background technology, provides a kind of key durance test device.
A kind of key durance test device, comprise power module, solenoid valve, feedback switch, cylinder and controller, described power module is connected with described controller and product to be measured, described solenoid valve air intake opening is connected external inflation equipment and cylinder respectively with gas outlet, and its Valve controlling end is connected with described controller; Described feedback switch is connected with controller, is installed on the leading inside of described cylinder, and described feedback switch is a magnetic sensor.
Further, described controller comprises multiple control signal output terminal and multiple feedback signal collection terminal, each described control signal output terminal connected electromagnetic valve, and each described solenoid valve is all connected with a described cylinder corresponding with it.
Further, described feedback signal collection terminal comprises the cylinder feedback collection end and the product feedback collection terminal being connected product that connect feedback switch.
Key durance test device of the present utility model, by arranging feedback mechanism, can calculate number of taps during button durable test exactly, and then guarantee the validity of key testing.
Accompanying drawing explanation
Fig. 1 is the schematic diagram in the utility model one embodiment.
Embodiment
Below in conjunction with accompanying drawing, a kind of key durance test device of the present utility model is further described.
A kind of key durance test device, for the durable test to press key equipment, as shown in Figure 1, it mainly comprises
Power module 1, powers for the consuming parts for proving installation.
Solenoid valve 2, be provided with air intake opening, gas outlet and the Valve controlling end for by-pass valve control switch, this solenoid valve 2 is for the switch of control cylinder.
Cylinder 3, inside establishes the piston rod for knocking test product, and this cylinder 3 is stretched out and retraction by the switch control rule piston rod of solenoid valve 2.
Feedback switch 4, for judging whether cylinder 3 completes a keystroke.
And controller 5, comprise the signal control signal output terminal for exporting Controlling solenoid valve 2 switch and receive the feedback signal input terminal 53 of feedback switch institute feedback signal, by can realize the restriction of button number of taps to arranging of controller 5 and judge whether test is normal according to feedback information.
Concrete, power module 1 is connected with controller 5 and product to be measured, solenoid valve 2 air intake opening and gas outlet are connected external inflation equipment and cylinder 3 respectively, its Valve controlling end is connected with the control signal output terminal of described controller 5, in the present embodiment, open when the Valve controlling termination of solenoid valve 2 receives high level signal, close when receiving low level signal.
In order to improve testing efficiency further, controller 5 adopts the industrial computer 51 being connected with polylith communication card 52, and the model of communication card 52 is PCI-7256.Wherein every block communication card 52 can connect two stations, and namely connect two test products, each station controls 8 cylinders by the control signal output terminal that 8 are arranged on communication card 52, can test 8 buttons.Maximum support 10 stations are tested simultaneously.When industrial computer 51 to the communication card 52 that will control send control knock instruction time, the signal output part on communication card then sends high level, makes solenoid valve 2 valve open, and cylinder 3 pairs of buttons knock.
Whether complete to monitor to knock, the inwall of the front end of cylinder 3 be provided with a feedback switch 4,
This feedback switch 4 is magnetic sensor in the present embodiment, magnetic part is installed additional in the rear end of piston rod, when the piston rod of cylinder 3 is released, the rear end of piston rod and the distance of cylinder front end reduce, when releasing completely, distance reduces to minimum, now magnetic part and magnetic sensor are apart from also minimum, magnetic sensor output low level signal; When piston rod is retracted, magnetic sensor exports high level signal.
Meanwhile, controller 5 is provided with feedback signal collection terminal 53, specifically comprises the product feedback signals collecting end 531 be arranged on industrial computer 51 and the cylinder feedback signal collection terminal 532 be arranged on communication card 52.These two feedback signal collection terminals can carry out feedback signal collection for dissimilar test product, if test product self is with feedback states, then the feedback end of test product is connected with product feedback signals collecting end 531, calculates by the feedback of product self number of times that button is pressed.If fruit product self is without feedback states, then feedback switch is connected with cylinder feedback signal collection terminal 532, calculates by the feedback of feedback switch the number of times that button is pressed.
Owing to adding the feedback of number of taps, because the leakage that various problem causes is struck or the problem of striking can not remedied by coding in test process, add the reliability of test.
By reference to the accompanying drawings embodiment of the present utility model is explained in detail above, but the utility model is not limited to above-mentioned embodiment, in the ken that those of ordinary skill in the art possess, various change can also be made under the prerequisite not departing from the utility model aim.
