Simultaneously, an error caused by a minute angle formed by the contact pin and the detected surface is avoided and precision is increased. Cost of the measuring instrument is low. The precision is high and an operation is simple.
Description
Technical field
The utility model belongs to the high-precision detection device field, particularly relates to a kind of pick-up unit of one dimension pattern.
Background technology
Contact pin type pattern detection method is one of method of step dimension detection.Its principle is to contact on measured surface with a very little contact pilotage, then move with the driver drives contact pilotage, contact pilotage is done moving up and down reciprocatingly along the profile of measured surface, then the displacement signal that this is small by sensor be converted to can calculation process electric signal, surface appearance feature or surface profile can record thus.
In recent years, the development of contact pin type pattern detector has obtained surprising progress, has had that function is many, cost is low, efficient is high, the multiplying power high.The contact pin type instrument of generally using at present adopts the detecting instrument of single contact pilotage type more, the longitudinal pressure of this kind detecting instrument is larger, just might be damaged to measured surface when contacting with measured surface, if when the hardness of measured surface is larger simultaneously, contact pilotage is worn, makes measuring accuracy be difficult to be effectively guaranteed.
Need badly in the middle of prior art in sum and want a kind of easy and simple to handle, detecting instrument efficient work to solve its existing weak point.
Summary of the invention
Technical problem to be solved in the utility model is: in order to overcome above-mentioned the deficiencies in the prior art, the utility model provides a kind of High Precision One Dimensional pattern detector that utilizes two contact pilotages, two guide rail structures.
