1. Field of the Invention
The present invention relates to a cleaning structure, and more particularly to a cleaning structure for an induction reader.
2. Description of the Prior Art
In order to maintain accuracy during movement, the existing machines are usually provided with a ruler 10 and an induction reader 20 (as shown in
The cleaning structure 30 contacts the obstacles in a surface-to-surface manner, when impacting the obstacles with front surface and bearing the whole weight of the obstacles, the cleaning structure 30 is likely to deform and must be replaced frequently, which not only wastes the material but also increases cost.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.
The primary objective of the present invention is to provide a cleaning structure for an induction reader, wherein the cleaning structure utilizes a guiding portion with a predetermined angle to clean off the obstacles.
To achieve the above objective, a cleaning structure for an induction reader is mounted on an induction reader and moves with respect to a ruler. The cleaning structure comprises: a removing portion with a predetermined angle or curve, the removing portion is provided with an assembling portion at one side thereof facing the induction reader, and on the other side of the removing portion is formed an abutting portion. By such arrangements, the angle or curved type clean structure can use the slope of the removing portion to contact and push the obstacles towards both sides of the ruler. The cleaning structure not only has a light structure weight but also the resistance against pushing the obstacles is reduced.
The present invention will be clearer from the following description when viewed together with the accompanying drawings, which show, for purpose of illustrations only, the preferred embodiment in accordance with the present invention.
Referring to
What follows are the descriptions of two embodiments of the cleaning structure 30:
First, angle type: the removing portions 40 of the two cleaning structures 30 are (as shown in
Second, curved type: the removing portions 40 of the two cleaning structures 30 are (as shown in
For a better understanding of the present invention, reference should be made to
When in use, the cleaning structure 30 is mounted to the surface of the induction reader 20 through the assembling portion 50, and when the induction reader 20 moves relative to the ruler 10, the abutting portion 60 of the cleaning structure 30 contacts the ruler 10, and the removing portion 40 of the cleaning structure 30 moves along with the induction reader 20 to clean off the obstacles on the ruler 10. By such arrangements, the angle or curved type clean structure 30 can use the slope of the removing portion 40 to contact and push the obstacles towards both sides of the ruler 10.
To summarize, a cleaning structure for an induction reader is mounted on an induction reader and moves with respect to the ruler. The cleaning structure comprising a removing portion which is formed with a predetermined angle or curvature. The cleaning structure moves along with the induction reader to clean the obstacles off the scale. The cleaning structure not only has a light structure weight but also the resistance against pushing the obstacles is reduced.
While we have shown and described various embodiments in accordance with the present invention, it is clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
