Description

A kind of many veneers pick-up unit

Technical field

The present invention relates to a kind of many veneers pick-up unit, belong to electric detection technique field.

Background technology

At present at the master control circuit plate of such as laser equipment etc. by being all by electronic circuit board, relay board and control panel three pieces of wiring board compositions, its effect forms the space encoding modulation having controlled laser intelligence field, due to these three pieces of circuit board functions, signal mode is different, therefore in production, use and corresponding separately detection must be done to it respectively in debugging, and current checkout equipment closely can detect for single signal, thus it is complicated to cause each circuit board performance detecting process, detection efficiency is low, accuracy of detection is also relatively low, at least three kinds of pick-up units must be used to an equipment simultaneously, cause structure of the detecting device also relative complex, use inconvenience, thus seriously reduce the quality stability of laser equipment and increase manufacturing cost and testing cost, follow that to need to develop a kind of structure simple, use flexible aspect just and the novel checkout equipment that three pieces of circuit boards detect simultaneously can be met simultaneously.

Summary of the invention

The object of the invention is just to overcome above-mentioned deficiency, provides a kind of many veneers pick-up unit.

For achieving the above object, the present invention is achieved through the following technical solutions:

A kind of many veneers pick-up unit, by housing, control circuit, operating assembly and connectivity port are formed, wherein control circuit is positioned at enclosure interior, operating assembly and connectivity port are embedded in housing outer surface respectively and are electrically connected with control circuit, operating assembly is by rotary switch, toggle switch, pilot lamp and nixie display are formed, control circuit is connected and composed by governor circuit and code identification circuit electrical, governor circuit is wherein made up of microprocessor and crystal oscillator, and crystal oscillator and microprocessor are electrically connected, code identification circuit is made up of three pieces of CMOS standard logic circuits chips, wherein one piece of CMOS standard logic circuits chip one end and governor circuit are electrically connected, the other end is electrically connected with other two pieces of CMOS standard logic circuits chips simultaneously.

Microprocessor is ATmega2561 is main control chip.

Three pieces of CMOS standard logic circuits chips are made up of one piece of 74AC138 (DIP16) and two pieces of 74AC240 (DIP16), and wherein 74AC138 (DIP16) and governor circuit are electrically connected.

The pick-up unit that the present invention is more traditional, has the advantages that structure is simple, detection efficiency is high and detection precision is high, can be widely used in the testing of multiple circuit, thus substantially increases work efficiency and the work precision of electric circuit inspection.

Fig. 2 is governor circuit schematic diagram;

Fig. 3 is housing operating assembly structural representation.

Embodiment

As shown in Figure 1, a kind of many veneers pick-up unit, by housing 5, control circuit, operating assembly and connectivity port 6 are formed, wherein control circuit is positioned at housing 5 inside, operating assembly and connectivity port 6 are embedded in housing 5 outside surface respectively and are electrically connected with control circuit, operating assembly is by rotary switch 1, toggle switch 2, pilot lamp 3 and nixie display 4 are formed, control circuit is connected and composed by governor circuit and code identification circuit electrical, wherein governor circuit is that main control chip microprocessor and crystal oscillator are formed by ATmega2561, and crystal oscillator and ATmega2561 are main control chip microprocessor is electrically connected, code identification circuit is made up of one piece of 74AC138 (DIP16) and two pieces of 74AC240 (DIP16), wherein 74AC138 (DIP16) one end and governor circuit are electrically connected, the other end is electrically connected with two pieces of 74AC240 (DIP16) simultaneously.

During test, by electron plate to be measured or relay board or control panel connection corresponding to connectivity port of the present invention respectively, then switch on power, power light is lighted, then, after adjustment rotary switch selects to want measurement circuit plate, the corresponding interface pilot lamp is bright, and standby indicating lamp is bright.

Press " startup " button, " standby " pilot lamp goes out, and " detection " pilot lamp is bright, and tester is by the automatic output of the microprocessor measurement and control signal to electron plate or relay board or control panel, detector, according to each circuit board output signal and logical sequence thereof, detects the correctness of each signal successively.

After detection terminates, " detection " pilot lamp goes out, and detector indicator provides testing result, " normally " or " fault " simultaneously.To be out of order position code by numeral method time " fault ", according to failure code, can to repair by fast finding trouble location.

By reference to the accompanying drawings the preferred embodiment for the present invention is described in detail above; but the present invention is not limited to above-mentioned embodiment; in the ken that those of ordinary skill in the art possess, can also make a variety of changes under the prerequisite not departing from present inventive concept and all fall into this programme protection domain.
