Specific implementation mode
For technology contents, structure feature, realization principle and the objects and the effects of the utility model are described in detail, with
Lower combination embodiment simultaneously coordinates attached drawing to be explained in detail.
The utility model discloses a kind of disconnected post detection devices of computer keycap support frame, for detecting computer keycap support frame
Whether the pillar 20 on 2 fractures, as shown in Figures 1 to 5, including operation console 10 and detection circuit.Operation console 10 is arranged for
Computer keycap support frame 2 to be detected is placed, several open type key switches 4 are provided in detection circuit, key switch 4 includes bottom
Seat 40 and guide post 41, pedestal 40 are connected with guide post 41 by elastic component, and guide post 41 is convexly equipped in the supporting surface of operation console 10, works as computer
When keycap support frame 2 is positioned on operation console 10, several guide posts 41 and several pillars 20 1 on detection computer keycap support frame 2
One corresponds to, and when the computer keycap support frame 2 is pressurized, several pillars 20 push corresponding guide post 41 to move down respectively, make
Corresponding key switch 4 is connected.
Computer keycap support frame with above structure breaks post detection device when being worked, and powers on, by computer
Keycap support frame 2 is positioned on operation console 10, at this point, each pillar 20 on computer keycap support frame 2 be respectively supported at it is each
On the guide post 41 of key switch 4, downward pressure then is imposed to computer keycap support frame 2, under the thrust of pillar 20
Guide post 41 moves down so that and the working condition of key switch 4 changes, if some pillar 20 fractures, corresponding to
Guide post 41 is motionless, which is in nonconducting state, to pass through the break-make for detecting detection circuit
Whether it can be learnt that there is pillar 20 to fracture, detection speed is fast, as a result accurately, and does not allow to be easy to miss inspection.After being fractureed due to pillar 20
It cannot replace, so need to only detect whether there is the pillar 20 to fracture on computer keycap support frame 2, without knowing specifically
Which root, so, in the present embodiment, all key switches 4 are connected in series in detection circuit, referring to Fig. 3, when to computer
When the force of keycap support frame 2 pushes, if detection circuit is connected, which is non-defective unit, if detection
Circuit is not turned on, then turning out the computer keycap support frame 2 has the pillar 20 to fracture.All key switches 4 are all strings
What connection linked together, so only all guide posts 41 can move down so that all conductings of key switch 4 could make inspection
Slowdown monitoring circuit is connected, meanwhile, as long as fractureing there are one pillar 20, key switch corresponding with the pillar 20 4 cannot be connected, this
When, detection circuit is in nonconducting state, then just can determine that the computer keycap support frame 2 is defective products.
Further, testing result is checked for convenience, the disconnected post detection device of the utility model computer keycap support frame
Detection circuit is additionally provided with the signal lamp 5 for prompting testing result, which is arranged on operation console 10, when being detected
Computer keycap support frame 2 when being defective products, detection circuit conducting, signal lamp 5 just accordingly provides signal, such as non-defective unit brilliant green
Lamp, defective products send out a warning.
In another embodiment of the disconnected post detection device of the utility model computer keycap support frame, it is additionally provided with to being placed on behaviour
Make the automation laminating mechanism that the computer keycap support frame 2 on platform 10 imposes downward pressure, please refers to Fig.1.Preferably, the pressing
Mechanism includes supporting rack, driver and pressing plate 32.Supporting rack is fixed on operation console 10, and driver is mounted on supporting rack
On, pressing plate 32 is arranged in the surface of operation console 10, is connect with driver, can be under the driving of driver to computer key to be detected
Cap support frame 2 imposes downward pressure.After placing computer keycap support frame 2, start driver work, drive belts dynamic pressure plate
32 move down, while setting the stroke of pressing plate 32 so that are not continued to down when the supporting surface of pressing plate 32 and operation console 10 contacts
It presses, at this point, under the promotion of the pillar 20 on computer keycap support frame 2, the guide post 41 on key switch 4 will be to 40 side of pedestal
To movement, triggering key switch 4 is connected, and is connected if all pillars 20 are all intact, all key switches 4,
Detection circuit is connected, and is judged as non-defective unit, if some pillar 20 fractures, corresponding key switch 4 cannot be connected, to
Corresponding detection circuit or detection branch cannot be connected, and send out the detection signal of defective products.After the completion of detection, driver drives
Pressing plate 32 returns to original position, since the guide post 41 of key switch 4 is connected with pedestal 40 by elastic component, after pressing plate 32 playbacks, leads
Pressure on column 41 disappears, and guide post 41 bounces back into origin-location again, and key switch 4 is again automatic to be restored to off-state.Further
, supporting rack include be mounted at 10 4 angles of operation console four cylinder support elements 30 being upwardly extended along operation console 10 and with
The support plate 31 of four support elements 30 connection, driver are mounted in support plate 31.Preferably, driver includes cylinder 33 and peace
Piston rod 34 on cylinder 33, pressing plate 32 are connect with piston rod 34.In addition, for the ease of designing the stroke of pressing plate 32, this
In embodiment, automation laminating mechanism further includes the limiting plate 35 being arranged on support element 30, and limiting plate 35 is arranged in support element
Between 30 and operation console 10, through-hole is provided on limiting plate 35, piston rod 34 is connect across through-hole with pressing plate 32, in this way, opening
Before detecting work, pressing plate 32 is tightly attached to the bottom surface of limiting plate 35, and after cylinder 34 starts, piston rod 34 is with 32 downlink of dynamic pressure plate, inspection
It surveys after the completion of work, pressing plate 32 is out of service when being moved at limiting plate 35
In order to increase stability of the computer keycap support frame 2 on operation console 10, in the present embodiment, on operation console 10 also
It is provided with locating template 11, locating template 11 is for fixing computer keycap support frame 2 to be detected.
Above disclosed is only the preferred embodiments of the utility model, cannot limit the utility model with this certainly
Interest field, therefore equivalent variations made according to the patent scope of the utility model still fall within the utility model and are covered
Range.
