Description
Technical field
The utility model relates to pick-up unit, is specifically related to a kind of automatic detection device of capacitance type touch key.
Background technology
Comparatively high-end household appliances all control based on capacitance type touch key now.Mechanical key before comparing, it is easy that capacitance type touch control keys has manipulation, the advantages such as long service life.In order to ensure producing qualified product, household electrical appliances producer needs to detect the various functions of product before product rolls off the production line, and which includes the detection of capacitance type touch key.Now general detection method is by artificial mode, is pointed and presses capacitance type touch key one by one, then judge that whether each button is normal by operator.
Although the detection method of manual mode can judge that whether each button is normal to a certain extent, there is some following shortcoming in it: is first reduction of production efficiency.If button is many, operator detects a button to be needed to take a long time.In production plant, often detecting operation is produce the efficiency bottle neck of line, constrains the lifting of producing line efficiency, is unfavorable for large-scale production; Next is that fault recall rate is lower.When operator occurs that work carelessness or operation were not at that time, some buttons can be missed.The risk that faulty item flows to market can be increased so undoubtedly.
Summary of the invention
For the defect existing for above-mentioned existing manual detection capacitance type touch key mode, the utility model object is the automatic detection device providing a kind of capacitance type touch key, to replace the manual detection of producing line.This automatic detection device can be enhanced productivity greatly, and promotes the fault recall rate of button.
In order to achieve the above object, the utility model adopts following technical scheme:
The automatic detection device of capacitance type touch key, comprise pick-up unit, tool circuit plate, display device, described pick-up unit is connected with tool circuit plate by communication interface, and described tool circuit plate and display device are electrically connected, and described pick-up unit comprises base plate and upper cover, described upper cover is positioned on described base plate, is provided with the conducting block corresponding with circuit-under-test plate button in described upper cover.
When needs detect capacitance type touch key, circuit board is positioned on the base plate of pick-up unit, the touch key-press of circuit-under-test can contact good with the conducting block coupling in upper cover, according to the principle of capacitance type touch key, after conducting block contact button, there is the effect that staff touch key-press is same; Pick-up unit powers on, circuit-under-test plate obtains power supply simultaneously, and the microcontroller electrification reset on circuit-under-test plate, then reads the state of each touch key-press respectively, if all buttons all contact with conducting block, then send a specific coding A in tool circuit plate; If detected that button is not pressed, then send another specific coding B; Can judge coding after tool circuit plate receives coding, if receive coding A, then show test on the display apparatus and pass through, if receive coding B, then failure code be shown; Thus operator according to the content of display device reality, can take different action, if display is passed through, then then test next block circuit board, if display failure code, then circuit-under-test plate is delivered to helpdesk's maintenance.
One as the automatic detection device of the utility model capacitance type touch key is improved, described stating in tool circuit plate is provided with microcontroller, this microcontroller sends coding for the microcontroller received in circuit-under-test plate, and this coding is judged, and export corresponding result to display device.
Another kind as the automatic detection device of the utility model capacitance type touch key improves, and described conducting block is separate, does not have electric connecting relation each other, to ensure the accuracy that each capacitance type touch key detects.
As another improvement of the automatic detection device of the utility model capacitance type touch key, described display device is digital tube display device.
From the above, the utility model compared with prior art, has following beneficial effect:
The automatic detection device of capacitance type touch key of the present utility model, can replace the manual detection of producing line, great production efficiency, improves the fault recall rate of button simultaneously, ensure that the quality of product.

Embodiment
Accompanying drawing, only for exemplary illustration, can not be interpreted as the restriction to this patent.
To those skilled in the art, in accompanying drawing, some known features and explanation thereof may be omitted is understandable.
Below in conjunction with the Figure of description in the utility model, be clearly and completely described the technical scheme in utility model, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, for the fundamental diagram of the automatic detection device of the utility model capacitance type touch key, comprise pick-up unit 1, tool circuit plate 2, digital tube display device 3, described pick-up unit 1 is connected with tool circuit plate 2 by communication interface 4, and described tool circuit plate 2 is electrically connected with digital tube display device 3.As shown in Figure 2, described pick-up unit 1 comprises base plate 10 and upper cover 11, and described upper cover 11 is positioned on described base plate 10, is provided with the conducting block 110 corresponding with circuit-under-test plate 5 button 50 in described upper cover 11, wherein this conducting block 110 is separate, does not have electric connecting relation each other.Wherein, microcontroller U2 is provided with in this tool circuit plate 2.
In the present embodiment, circuit-under-test plate has 8 touch key-press K1-K8, and a microcontroller U1.Eight conducting block E1-E8 are had in upper cover, and one block of tool circuit plate containing microcontroller U2, the display device containing 28 segment numeral pipes.
Concrete performing step is:
The first step: circuit-under-test plate is put into pick-up unit by operator, is fixed on base, and the touch key-press K1-K8 of circuit-under-test plate contacts well with the conducting block E1-E8 detecting frock.
Second step: pick-up unit powers on, circuit-under-test plate obtains power supply simultaneously.Microcontroller U1 electrification reset on circuit-under-test plate, then reads the state of each touch key-press of K1-K8 respectively.Present definition byte has 8, bit0-bit7, and each button correspondence is one: K1 corresponding bit0 wherein, by that analogy, and the corresponding bit7 of K8.When U1 detect there is no button time, corresponding position is 1, otherwise is 0.If all buttons all contact with conducting block, then send a specific coding 0xFF to the microcontroller U2 of tool circuit plate.If detected that button is not pressed, then send another specific coding.
3rd step: the microcontroller U2 of tool circuit plate receives coding, then judges.If receive coding 0xFF, then show " FF " on the display apparatus, represent that test is passed through.If receive other codings of coding, such as 0x11, then show failure code " 11 " on the charactron of display device.
4th step: operator, according to the content of display device reality, takes different action.If display is passed through, then then test next block circuit-under-test plate, if display failure code, then circuit-under-test plate is delivered to helpdesk's maintenance.
In sum, be the utility model embodiment content, and obvious embodiment of the present utility model is not limited in this, it according to different application environment, can utilize functional realiey corresponding demand of the present utility model.
