Description
Technical field
The present invention relates to a kind of a kind of pointer installation method of automobile instrument field, in particular to a kind of step motor type electronic automobile meter pointer installation method.
Background technology
Along with the development of auto industry, automobile instrument technology is also in development at full speed.Pointer instruction is because having the advantages such as the intuitive of display always in occupation of leading position, and the control of pointer is at present substantially all adopt stepper motor to drive.Step motor type electronic instrument has the many merits such as reproducible, the linearity is high, fast response time, registration, reliability are high, has been widely recognized and applies.Although stepper motor exists plurality of advantages, because of its fine structure, motor needle shaft is stressed is improperly easy to the potential failure causing stepper motor, can impact the performance of instrument.Therefore carrying out the design of scientific and reasonable pointer installation process and control to be promotes instrument quality, reduce and one of key factor of domestic and international gap of the same trade, on improving the market competitiveness, also there is very important impact.
The various running state information of vehicle in the automobilism of the step motor type electronic instrument course of work, as the signal such as the speed of a motor vehicle, engine speed, output of pulse signal is gone out in automobile instrument by the sensor sensing be arranged on vehicle, after the signals such as the speed of a motor vehicle collected, rotating speed are processed by the single-chip microcomputer of gauge internal by automobile instrument, again by output of pulse signal to corresponding stepper motor, the needle shaft carrying out Driving Stepping Motor rotates certain angle according to the direction of setting.When non-overload, the rotating speed of motor, the position of stopping only depending on frequency and the umber of pulse of pulse signal, and not by the impact of load change, namely add a pulse signal to motor, motor then turns over a step angle.Pointer due to instrument is arranged on the needle shaft of stepper motor, therefore can observe directly the running state information such as the speed of a motor vehicle, rotating speed of vehicle from the indicating positions of pointer.As a same reason, the relevant information such as fuel oil, water temperature of automobile exports corresponding resistance signal to automobile instrument by sensor, automobile instrument is by internal calculation process, the final needle shaft running exporting corresponding pulse signal Driving Stepping Motor, indicate the information such as the fuel oil of automobile, water temperature, ensure traffic safety.
In the production process of step motor instrument, the Process Design that pointer is installed and control are the keys ensureing instrument quality.At the beginning of stepper motor technology is applied to automobile instrument, lack experience owing to installing control to the pointer of stepper motor, the production model of the artificial press mounting of pointer of most employing, often cause stepper motor in pointer installation process, occur various potential inefficacy, cause instrument in use to occur the quality problem such as pointer clamping stagnation, shake.After pointer is installed on stepper motor needle shaft, visual test cannot be carried out to its fiting effect, for ensureing that needle locating is accurate, instrument is reliable, must carry out effective Detection & Controling to the process of pressing.
Summary of the invention
The object of the invention is to the above problem overcoming prior art existence, a kind of step motor type electronic automobile meter pointer installation method is provided.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention is achieved through the following technical solutions:
A kind of step motor type electronic automobile meter pointer installation method, comprises the following steps:
Step 1) scanning product bar code also judges, meet preset value and enter step 2, otherwise appointed area is put in taking-up;
Step 2) product loaded frock and start and press-fit process;
Step 3) equipment powers on to instrument, instrumentation relevant information, qualifiedly enters step 4, otherwise takes out and put into appointed area;
The power-off of step 4) instrument, motor needle shaft returns back to mechanical zero;
Step 5) operating personnel are according to prompting put pointer, and pointer is positioned at mechanical zero;
Pointer pressing puts in place by step 6) equipment automatically, detects and record pressure force, if pressure force is qualified, enters step 7, otherwise instrument power-off, take out and put into appointed area;
Step 7) instrument re-powers, if pointer to operate supreme electrical zero from mechanical zero, enters step 8, otherwise instrument power-off, take out and put into appointed area;
Step 8) write station code also judges whether qualified, qualifiedly enters step 9, otherwise instrument power-off, take out and put into appointed area;
The power-off of step 9) instrument, if motor needle shaft goes to mechanical zero, terminates program, takes out instrument and to circulate subsequent processing, otherwise takes out and put into appointed area.
The invention has the beneficial effects as follows:
Automatic pressing equipment is furnished with the rotary cylinder of specialty, when instrument is placed into after in fixture, cylinder under program control, instrument is fixed by automatic rotation, simultaneous retractable cylinder moves the clamp portion of fixture automatically, pointer standing groove is blocked, can prevent staff from putting into the maloperation of pointer in advance, the handling safety of equipment can be ensured again.
Above-mentioned explanation is only the general introduction of technical solution of the present invention, in order to better understand technological means of the present invention, and can be implemented according to the content of description, coordinates accompanying drawing to be described in detail as follows below with preferred embodiment of the present invention.The specific embodiment of the present invention is provided in detail by following examples and accompanying drawing thereof.
Accompanying drawing explanation
Accompanying drawing described herein is used to provide a further understanding of the present invention, and form a application's part, schematic description and description of the present invention, for explaining the present invention, does not form inappropriate limitation of the present invention.In the accompanying drawings:
Fig. 1 workflow diagram of the present invention.
Detailed description of the invention
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the present invention in detail.
With reference to shown in Fig. 1, a kind of step motor type electronic automobile meter pointer installation method, comprises the following steps:
Step 1) scanning product bar code also judges, meet preset value and enter step 2, otherwise appointed area is put in taking-up;
Step 2) product loaded frock and start and press-fit process;
Step 3) equipment powers on to instrument, instrumentation relevant information, qualifiedly enters step 4, otherwise takes out and put into appointed area;
The power-off of step 4) instrument, motor needle shaft returns back to mechanical zero;
