Description

[0001] The present invention relates to a dust adsorber,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a low-dust-type robot that performs linear motion, and more particularly, to a low-dust-type robot capable of dividing and adsorbing a dust cover, .

Generally, it is applied to a machine tool, a robot, a conveyor, and the like. In the apparatus to which the linear reciprocating motion is applied, a linear motion guide is used as a linear motion guide There is a dusty robot.

These low-dust robots can be driven lightly and smoothly when connected parts are linearly driven, can make driving force and positioning more accurate, can maintain high precision for a long time, The demand is increasing accordingly.

The above-described low-dust robot includes a moving part driven in accordance with a direction and a distance driven by a rectilinear motion, and a moving block driven by the operation of the moving part while being connected and fixed with a part to be linearly moved.

Here, the moving driving unit is installed in a device such as a robot, to which linear motion is applied so as to linearly move the moving block. Dust generated in the applied device, various foreign substances generated in the work, There was a problem.

Accordingly, in order to prevent contaminants from flowing into the inside of the low dust robot through the upper side of the moving driving unit exposed to install the moving block, a dust cover covering the exposed upper side of the moving driving unit is installed.

On the other hand, a conventional dust cover is installed in a corrugated form and is wrinkled according to a driving distance, and covers the exposed portion of the moving driving part while folding it, thereby blocking foreign matter from entering the inside of the moving driving part from the outside.

However, in the case of the wrinkle-shaped dust cover, when the wrinkle is folded or spread in the moving process of the moving block, a gap with the moving driving portion is generated, and foreign matter is introduced into the gap.

Recently, a dust cover in the form of an iron plate having elasticity is applied to cover the exposed portion of the moving part in a state where the dust cover is fitted in the moving block, thereby minimizing the gap between the moving block and the moving part, A dust-less robot has been proposed which prevents foreign matter from entering.

This steel plate type dust cover is fitted in a moving block with an elastic material and is deflected at a driving position of the moving block in a closed state while covering an exposed portion of the moving driving portion and is returned to the original position by elasticity after driving. Thereby maintaining the sealed state.

As a result, the gap between the moving block and the moving driving portion is generated according to the driving of the moving block, thereby minimizing the inflow of foreign substances to the outside as compared with the pleated dust cover in which the contaminants are introduced. However, When the block is driven, there is a problem that it is difficult to prevent foreign substances from flowing into the moving driving part due to the gap generated on the connection part between the moving block and the dust cover.

In addition, when the moving block is repeatedly driven by the operation of the moving driving unit, the gap between the dust cover and the moving driving unit is gradually increased as well as the deformation of the dust cover due to the moving of the moving block, The accumulated foreign matter causes a failure of the moving driving unit, shortens the service life of the floating driving unit, and after a certain time, it is necessary to perform an operation to remove foreign matter from the moving driving unit while the moving driving unit is stopped. .

First, the base portion 110,

And a vacuum suction block 200, which will be described later, is installed at the upper end of each of the opposed sides.

Mounting portions 113 are provided on the opposite upper and side surfaces of the base body 111. [

The width and the depth of the base space 112 formed in the base body 111 do not have to be determined to be one of them and the width and the depth are determined in consideration of the installation of related parts and the like in the base space 112 And the length of the base space 112 can be determined in consideration of a predetermined reciprocating distance of the moving part 120 to be described later.

The mounting portion 113 of the base body 111 is constructed so that the vacuum suction block 200 to be described later can be seated and fixed horizontally along the longitudinal direction at the upper ends of both side surfaces of the base body 111.

Each of the vacuum connection holes 230 is connected through a connection hose It is preferable to be connected to each vacuum device.

In the case where the vacuum adsorption block 200 is divided into a plurality of vacuum adsorption blocks 200 as in the embodiment of the present invention, one vacuum connection hole 230 may be connected to each side of the vacuum adsorption block 200, It is preferable that a plurality of vacuum connection holes 230 are formed at equal intervals in each of the vacuum adsorption blocks 200 so that the vacuum adsorption units 221 and 221 have a uniform adsorption force.
