Description
Technical field
The invention belongs to carbon film potentiometer processing technique fields, more particularly to a kind of current potential based on double brush sampling method
The meter linearity, which synchronizes, continuously repairs etching system and repair and carving method.
Background technique
With accurate carbon film potentiometer in servo mechanism as the extensive use of feedback element, linearity just by
Step improves.It in its preparation process, is limited by spraying process, linearity room for promotion is limited.Therefore it needs at present auxiliary by repairing quarter
It helps and improves its linearity.Current repairs there are two types of quarter modes, i.e., discrete to repair quarter and single brush is asynchronous continuously repairs quarter, wherein to lead
The quarter mode of repairing of stream repairs quarter to be discrete, the advantage is that device structure is simple, and principle is to simulate equidistant the repairing point by point of worker's craft
It carves.However, this mode cannot traverse entire resistance diaphragm, so that two resistive linearity degree repaired between punctum are difficult to ensure,
And inefficiency；And at present it is existing continuously repair quarter mode, basic assumption is that carbon film thickness is only inclined in its length direction
Difference is consistent in width direction, and it is repaired and carves step to first pass through single brush measurement fixed carbon resister curve, then passes through comparison
Surveyed curve and ideal curve each section difference calculate each point and repair quarter depth and depict response curve as, carry out repairing quarter later,
Its disadvantage protruded is to have ignored the carbon film unevenly influence caused by resistance in width direction, and because its opened loop control side
Formula lacks effective Feedback, causes the superposition of error, causes the second half section fixed carbon resister linearity for repairing quarter second-rate, precision is difficult to
Control and in there is waste product.
Summary of the invention
It is existing discrete to repair quarter the invention aims to solve during the linear type carbon film potentiometer linearity repairs quarter
Mode not can guarantee its inefficiency of potentiometer overall linearity, and asynchronous discrete repair is carved the problems such as cumulative errors are excessive, proposed
A kind of potentiometer linearity based on double brush sampling method, which synchronizes, continuously repairs etching system and repair and carving method.
The present invention is achieved by the following technical solutions, and the present invention proposes a kind of potentiometer based on double brush sampling method
The linearity, which synchronizes, continuously repairs etching system, and the system comprises two brush A, B and Xiu Ke milling cutters being placed in parallel, described two electricity
The position for brushing and repairing quarter milling cutter is remained unchanged in the process relative position for repairing quarter；Described two brushes keep sampling area position
Vertical with X-direction, the gap between the sampling area position of described two brushes is referred to as sampling gap, it is described repair carve milling cutter with
Brush A is consistent in the Y direction；When repairing quarter process and carrying out, two brushes and repairs quarter milling cutter and be consistent in X-direction position, carbon
Film along X-axis negative direction uniform motion, while repair carve milling cutter in the Y direction according to two brushes sampling situation do feed motion completion cut
It cuts.
The present invention also proposes that a kind of potentiometer linearity based on double brush sampling method synchronizes continuous repair and carving method, including with
Lower step:
Step 1: prepare before repairing quarter；The quarter preceding preparation process of repairing includes potentiometric clamping and two brushes A, B and repairs

Journey relative position remains unchanged；Described two brushes keep sampling area position vertical with X-direction, and described two brushes are adopted
Gap between sample regional location is referred to as sampling gap, and the quarter milling cutter of repairing is consistent in the Y direction with brush A；
Step 2: measurement sampling gap length；Brush is adjusted to potentiometer carbon film any region, record brush A is read, and
Current raster ruler position is recorded, manually adjusting guide rail later moves brush A along X-axis negative direction, reads brush B in the process and reads
Number is until it is identical as mobile preceding brush A, and record grating scale current location, the difference of two positions is sampling gap length；
Step 3: zero process is sought；When repairing quarter beginning, two brushes are placed on starting end conductive silver band, starting servo electricity
Machine makes guide rail travel forward, and observation brush A reading seeks zero end, brush A is located at carbon film at this time when numerical value starts to become larger
Zero point；
Step 4: quarter process is repaired；After seeking zero, X-axis servo motor is at the uniform velocity moved along negative direction, while being calculated and being repaired quarter deeply
Degree, adjustment Y-axis servo motor position carries out repairing quarter, until moving to carbon film end and repairing terminates at quarter.
Further, quarter depth is repaired in the calculating specifically:
Carbon film both ends conductive silver band applies constant current with high stable constant current source, while acquiring brush A, B and starting end is led
Voltage U between electric silver bandA、UB；The resistance R between brush A and zero point is calculated according to Ohm's lawABetween brush A, B
Resistance RAB；For any time, the quarter depth of repairing of carbon film is indicated with following formula:
Δ l in formula --- repair quarter depth；
L --- carbon film width；
RAB--- the practical fixed carbon resister between sampled point A, B；
R0--- the expectation fixed carbon resister between sampled point A, B；
Deviation between Δ R --- sampled point B actual resistance and sampled point B location expectation resistance；
D --- sampling gap length；
It is actual repair quarter during, repair and carve depth as reference, while using RARegion expectation resistance R is carved with having repairedA0's
Difference repairs quarter depth as feedback modifiers are practical, to complete to repair quarter to whole.
The invention has the benefit that
1. improving since discrete repair carves the inconsistent problem of bring local linear degree as caused by different measurement intervals.Even
Continuous correction algorithm, which to repair, to be carved track and becomes a smooth continuous curve rather than discrete sampled point, so that potentiometer
The linearity be detached from measurement interval and be consistent the whole linearity, this has very for improving potentiometric feedback accuracy
Big practical significance.
2. shortening the overall processing time.Serial update to measure and repairs that quarter process is almost synchronous to be carried out, and traditional-handwork
Repair carve and it is preliminary realize automation it is discrete repair quarter be all by measurement process and Xiu Ke process alternately, compare these modes,
Its correction time further shortens, monolithic repair carve the time foreshorten to 30s-60s, improve potentiometric production efficiency.
Quarter error is repaired 3. effectively reducing.Double brush, which synchronizes, continuously to be repaired the mode at quarter and can accurately determine and repair quarter depth, and is led to
It crosses comparison to feed back it with the deviation for repairing quarter region and theoretical resistance, effective control to error may be implemented, and accidentally
Difference will not generate accumulative, raising overall precision, and rejection rate is effectively reduced.
