Embodiment
See also Fig. 1 and Fig. 2, a kind of button testing apparatus in serviceable life comprises: frame, attacking head and button feedback circuit is characterized in that: be connected with a rotating shaft between the said frame, the main shaft of drive motor links to each other with rotating shaft through keyway and drives the rotating shaft rotation.This rotating shaft is provided with four cams, along the axial equidistant arrangement of rotating shaft.Conflict in the top guide bar upper end that the below of each cam is provided with in said attacking head and this cam outer rim and this attacking head.When cam rotated along with rotating shaft, the guide rod that cam driven is equipped with spring pumped with key tap, thereby carried out durability test.Below attacking head, be provided with the button feedback circuit, the button feedback circuit is embedded in PCB and the organic glass compoboard on the framework soleplate, is designed with the location hole and the corresponding conducting cut-off circuit of orientable button on the pcb board.
Have one in the said rotating shaft and detect the move up and down counting assembly of number of times of attacking head, it passes its corresponding circuit of sensor and forms by being installed in photoelectricity on the electric machine main shaft.Revolve when rotating shaft and to turn around, the counting assembly counting adds up once.
One side of said frame is provided with a cabinet, and cabinet links to each other with frame, forms whole experimental machine.In cabinet, be provided with the circuit of demonstration and opertaing device work.Control circuit is installed on the cabinet sidewall, controls the operation of whole equipment.Through being installed in the touching-type monitor in the cabinet outside, the operational factor and the data of whole equipment are controlled, and can be read experimental result.Control circuit has connected button feedback circuit and drive motor through pin, and the conducting number of times of button measured in control test speed and record.Feedback circuit is that control circuit comprises the DSP65 series monolithic, power supply unit, tachogenerator, reed test feedback circuit, button CC, relay, components and parts such as touch display panel.
Please with reference to Fig. 3, the head of said attacking head is the range-adjustable formula, and it comprises and hit female head and be sheathed on the sub-head of strike that hits in female head that this strikes head can hit female head relatively and be shifted up and down.The female head of strike adopts with the sub-head of strike and is threaded, and the sidewall that hits sub is marked with scale mark.The screw knob is housed on the guide pillar of attacking head, and scalable is hit the relative distance (cooperating different test requests) of female head and son head, thus the stroke of control button test, the simulation truth.
