Description
Technical field
The invention belongs to automobile instrument manufacturing technology field, more particularly to a kind of automobile meter pointer press-fit equipment and its side
Method.
Background technology
In automotive electronics manufactures industry, as shown in figure 8, the assembling of automobile instrument is related generally to circuit board 2, liquid
Pointer 5, is then pressed on the stepper motor 8 of instrument board 6 by the assembling of crystalline substance screen 3 and lamp box 4, finally carries out bonnet 7 and face
The assembling of cover.
Wherein, pointer 5 be pressed into stepper motor 8 be specific to automobile instrument assembling Particular craft, press-in technique it is required
The critical field strictly to be provided in accordance with stepper motor supplier can be only achieved the yield of volume production.Its is electrical for the model of different motors
Can parameter have nothing in common with each other, but be pressed into the standard of technique except the scope of pressing-in force is different, other are all identicals, such as producer
The requirement of the 1.5mm metal single shaft stepper motors generally used is (see Fig. 9)：
1st, pressing direction must be vertical；
2nd, standard pressing-in force：Between 25 Ns to 120 Ns；
3rd, standard press-in speed：800 mm/mins；
4th, standard press-in height (height of the bottom surface of pointer 5 from the upper surface of instrument board 6)：1 millimeter, it is allowed to which error is ± 0.4
Millimeter；
5th, support must be arranged at motor bottom.
These parameters it is exceeded can cause product respectively quality problems be：Pressing-in force is easily rotating less than 25 Niu Zhizhen 5
During drop, pressing-in force is easily destroyed step-by-step motor structure more than 120 Ns, and the excessively slow pointer 5 of press-in speed is difficult to be pressed into, press-in
Excessive velocities stepper motor 8 easily bears excess impact, and press-in excessive height easily scrapes transparent protective shield in rotation process, is pressed into
The highly too low upper surface that instrument board 6 is scraped easily in rotation process.
As shown in Figure 10, solution commonly used in the trade at present is as follows：
Ensure the press-in vertical with motor drive shaft of pointer 5 using vertically moving pressure heads mechanism 9, use pressure sensor
The pressure value after press-in is perceived, to judge technique quality, the press-in speed of pointer 5 is controlled using stepping or servo linear motor, and
And pointer 5 is depressed into the height set, caused active force is pushed to offset using motor bottom support column 10, finally by
Whether detection device confirms the height of pointer 5 in the range of.Such scheme can be effectively ensured perpendicularity, pressure value, press-in speed,
But press-in height and motor support are often because the accumulative of product individual difference causes highly exceeded, final height detection apparatus report
Mistake produces part rejection.
Press-in height controls the reason for exceeded to have following several possibility：
After the completion of press-in, the height of pointer 5 is that stepping or servo linear motor are set, therefore is a definite value,
But because the thickness of the error of pointer 5 itself, the thickness error of instrument board 6, the error of the working of plastics of lamp box 4, circuit board 2 misses
Difference, and the gap of support column 10 and motor bottom can all have an impact to press-in height, wherein, support column 10 and motor bottom
Gap can be deformed circuit board 2 when pointer 5 is pressed into, and after press-in terminates circuit board bounce-back so as to causing pointer to be surveyed
Measure higher, similarly, if support column 10 is too high, also can produce back-flexing in product fixation procedure, cause pressing to terminate to solve
Except after locking circuit board 2 reply it is straight, cause pointer measurement it is relatively low.
Stepping or servo linear motor and measurement error can accomplish to be less than 0.01 millimeter by type selecting, substantially can be with
Ignore, therefore these above-mentioned cumulative errors are all based on product error in itself and produced, it will usually the standard more than ± 0.4 millimeter
Press-in height, if press motor supplier standard management and control, can make elevation carrection report an error and repair rate raising, if pressing product batches
Size difference is pressed into height to adjust motor, and device efficiency and reliability can substantially reduce, if relaxing requirement, can increase visitor
Rate is told, yield is bigger, and product control is just more difficult to.
