Description
Technical field
The present invention relates to the automatic resistance trimming work station of automobile sensor technical field more particularly to a kind of automobile sensor with
And resistance trimming principle.
Background technique
Current divider is one kind of automobile sensor, and current divider is for measuring DC voltage, when passing through resistance according to direct current
It is made in the principle that resistance both ends generate voltage.In fact, current divider is exactly the resistance of a resistance value very little.It is needing to survey
When measuring biggish DC current, one can be will appear at the both ends of current divider when the DC current of big ampere flows through automobile sensor
At this moment the voltage of millivolt level measures this voltage with millivolt voltmeter, then this voltage is converted using Ohm's law I=U/R
At electric current, the measurement of high current is completed with this.
Current divider is mainly made of the copperhead of copper sheet and copper sheet two sides, and the two groups of contacts in interior outside are arranged on copperhead.It is shunting
In the Conventional process of device mass, it is desirable that the resistance of all products is that the numerical value when side of standard is qualified.In debugging product
When resistance, the contact in outside is connected to power supply, and the contact of inside is connect with test instrumentation, the then product when the resistance measured is bigger than normal
It is unqualified；When the resistance measured is less than normal, current divider can be removed, the copper sheet of current divider is manually cut with handsaw or
Artificial pickling increases its resistance value until resistance value is standard figures to reduce cross-sectional area, using this.
During resistance trimming above, needs manually to carry out the electric connection of two groups of contacts, then tested, for not
Same test result, then release electric connection and product is sorted out.When the resistance measured is less than normal, a kind of processing method is people
Work cuts copper sheet, is then electrically connected and is tested again, sort out further according to different test results and debug again.It operates numerous
It is trivial, low efficiency, it is easy to when debugging again that original resistance resistance less than normal that becomes is bigger than normal and scrap, the stability of production
Low, relatively high to the proficiency and skill requirement of operator, it is big that resistance value adjusts risk of exceeding criterion.Another processing of artificial pickling
Since the concentration of acid cleaning process acid and the time of pickling are difficult to quantified controlling, resistance value adjusts exceeded risk and equally also compares method
It is higher.
For the defect of above-mentioned traditional handicraft, there are many improved plans, now retrieve one application No. is
CN201410647391.6, the patent of invention of entitled " a kind of correcting device of current divider resistance ".The principle of the patent of invention
Are as follows: the T-type terminals at the both ends of current divider are placed on to the second electrode on piece of support rim, the fixation hole fixation of current divider is matched
Conjunction contacts on positioning pin, and with the third electrode slice in fixed plate, if having gap between third electrode slice and current divider, adds
The conductive spacer for entering appropriate thickness after current divider places, by the jettron of lower cylinder, makes piston rod be connected with first electrode
Piece one end moves downward the T-type terminals up to being pressed into contact with current divider, recloses test switch button at this time, checks galvanometer
Pointer whether nulling if galvanometric pointer is directed toward zero illustrates product qualification, disconnect test switch button and pneumatic at this time
Switch, withdraws the piston rod of cylinder, takes out product and is placed on qualified products set-down location；If galvanometric pointer is directed toward negative
Value, illustrates that product is unqualified, disconnects test switch button and jettron at this time, withdraws the piston rod of cylinder, takes out product
It is placed on substandard product set-down location；If galvanometric pointer is directed toward positive value, illustrate that resistance value is higher, disconnects test at this time and open
Button is closed, corresponding resistor disc is amputated on resistor disc with handsaw, is again started up test switch button, check galvanometric pointer
It is directed toward, until galvanometric pointer is directed toward zero, keeps product modification qualified, press jettron, withdraw the piston rod of cylinder, take
Qualified products out.
The invention effectively simplifies resistance trimming operation, is all once electrically connected, is had to current divider without each resistance trimming
Effect, which is reduced, to be occurred careless omission and leads to underproof product.But there is also defects for the invention, and such as: between contact and current divider
It needs to increase gasket to be adjusted, inconvenient for operation, low efficiency；Internal closed-frame structure, the working space of handsaw are limited；
The tower structure intensity difference, occupied space are big；Cylinder is upper, and when piston is taken exercises downwards, operator is easy to operate by mistake, by hand
Depressed position is put in, there are security risks.The invention still needs manually to carry out handsaw, and mechanization degree is not high, waste of manpower
Resource still compares the experience degree and proficiency for relying on artificial handsaw cutting.
Application No. is CN200810029012.1, the hairs of entitled " a kind of automatic resistance regulating machine of resistor type strain foil " for an another piece
Bright patent, the invention include base and be installed on base be used for fixed resistance formula foil gauge workbench, which is characterized in that
Further include: the grinding head above workbench for resistance strain plate of polishing, grinding head are installed on a motor output shaft；
Fixing motor and the polishing head feeding mechanism of drive motor vertical table movement；For installing polishing head feeding mechanism and driving
It polishes transverse moving mechanism of the head feeding mechanism with respect to workbench transverse shifting, transverse moving mechanism is across on workbench；With
In installation transverse moving mechanism and drive transverse moving mechanism with respect to the longitudinal moving mechanism of workbench longitudinal movement；For with electricity
The probe that solder joint contacts on resistive foil gauge, probe are coupled by conducting wire with resistance detecting circuit；Governor circuit, with each mechanism with
And resistance detecting circuit connection, for controlling each unit coordinates work.
The invention reduces the working strength of worker, and production efficiency is greatly improved, and the operation is stable, makes to produce
The precision of product is also greatly improved.But the invention is mainly used in resistance strain plate semi-finished product, with automobile-used sensing
The copper sheet resistance trimming field of device is not consistent, and be control grinding head to same a line or same row be put in the foil gauge half of plane at
Product movement is polished, and needs to be pre-positioned operating path for different model foil gauge semi-finished product, processing efficiency is not very high.
Probe is needed to be permanently connected to foil gauge semi-finished product until polishing terminates in bruting process, the vibration of grinding head is likely to result in measuring
Deviation, probe are chronically in vibration conduction and are also easily damaged, and increase operating cost.Again in view of subsequent foil gauge semi-finished product
Processing installation, the resistance value of foil gauge finished product still have deviation, and the resistance value that still carry out subsequent product adjusts again.
