Description
Technical field
The present invention relates to a kind of strain ga(u)ge resistance and adjust equipment, particularly a kind of strain ga(u)ge automatization resistance trimming dress
Put and resistance trimming method, automatically adjust strain gauge resistance and make up to nominal resistance.
Background technology
Strain ga(u)ge (hereinafter referred to as strain gauge) is the sensing element utilizing " resistance-strain " principle, generally uses base
The processes such as the end prepares, exposes, corrosion form strain gauge graphic structure unit.Due to foil roll compacting and strain gauge manufacture by mistake
Difference, causes sensitive grid thickness, width etc. can there is micron to nano grade dispersion, and after strain gauge corrosion molding, resistance value cannot be whole
Reach nominal resistance, be constantly present certain deviation, it is impossible to be directly used in test and measure.In order to ensure that strain gauge resistance meets
Application requirement, needs to be adjusted reaching nominal value to its resistance.
At present, the method that strain gauge resistance adjusts has: manual machinery Ginding process, semi-automatic mechanical milling method, craft
Chemical attack method of adjustment.
It is to make sensitive grid sectional area reduce by mechanical lapping to promote resistance, generally use that manual machinery grinds resistance trimming method
DC micromotor with grinding head operates, and grinding head is typically with sand rubber or the rayon balls that is moistened with abrasive material.Adjust
During whole resistance, manual mobile motor makes abrasive contact strain gauge sensitive grid region, rotarily drives grinding head rotation by motor right
Sensitive grid is polished, thus realizes the target that resistance adjusts.
Semi-automatic mechanical grinding device operation logic is similar to preceding method, and different piece is to be become by artificial mobile motor
Automatically driving for three-axis moving, back and forth or left and right upper and lower by grinding head is moved and is realized resistance trimming, simultaneously detection strain gauge resistance
Value, controls all parts work.Although tentatively realizing equipment resistance trimming, but need artificial replacing abrasive material ball or band sand rubber.
Said method, in actual mechanical process, the change of strain gauge resistance is by being applied to the pressure on sensitive grid surface, mill
The factors such as the hardness of material and particle diameter, belong to cold working, easily there is polishing uneven, and polishing rear surface stress is concentrated, people
For problems such as factor impact are big, efficiency is slow simultaneously, and labor intensity is big.Although semi-automatic mechanical grinding device can replace one
Divide operative, but still cannot improve the problems referred to above.
Manual chemical resistance trimming method is to use chemistry resistance trimming liquid to sensitive grid surface or side etch, reduces sectional area and adjusts
Resistance.It is generally divided into 4 steps: rough adjustment, careful adjustment, neutralize, clean.Resistance trimming carrier is absorbent cotton or non-woven fabrics etc..Manual
The shortcoming of chemistry resistance trimming method is to neutralize cleaning to waste time and energy, and easily residual corrosive liquid causes resistance overproof or other defect；Product
Quality is affected by human factors bigger；Resistance trimming efficiency is low.
In a word, said method or equipment resistance trimming efficiency is low, labor intensity is big, in the course of processing anthropic factor quick to strain gauge
Sense quality impact is bigger, it is impossible to meet the demand that the efficient bulk industrial of high-quality strain gauge produces.
