Linear encoder and method of adjusting a gap between a sensor unit and a scale of the linear encoder
First Claim
Patent Images
1. A linear encoder, comprising:
- a housing;
a scale disposed within the housing;
a sensor unit disposed within the housing facing the scale with a gap between the sensor unit and the scale, the sensor unit being configured to scan the scale and obtain position information;
at least one adjustment hole for a gap adjustment disposed in at least one of the housing and an end cover of the housing at a position corresponding to a position of the gap; and
a removable cover on the at least one adjustment hole,wherein the at least one adjustment hole is configured such that a gap gauge is insertable into the gap between the scale and the sensor unit through the at least one adjustment hole when the cover is removed.

Abstract
A linear encoder includes a housing, a scale disposed within the housing and a sensor unit disposed within the housing facing the scale with a gap between the sensor unit and the scale. The sensor unit is configured to scan the scale and obtain position information. At least one adjustment hole for a gap adjustment is disposed in at least one of the housing and an end cover of the housing at a position corresponding to a position of the gap.

7. A method of adjusting a linear encoder comprising a housing, a scale disposed within the housing, a sensor unit disposed within the housing facing the scale with a gap between the sensor unit and the scale, the sensor unit being configured to scan the scale and obtain position information, and at least one adjustment hole for a gap adjustment disposed in at least one of the housing and an end cover of the housing at a position corresponding to a position of the gap, the method comprising:
-
removing a cover installed on the at least one adjustment hole so as to expose the at least one adjustment hole; inserting a gap gauge between the scale and the sensor unit through the at least one adjustment hole; adjusting a position of the sensor unit so as to adjust the gap between the sensor unit and the scale; and removing the gap gauge and re-installing the cover.
