- the two brush rollers 3A and 3B are disposed and are configured to rotate in opposite directions to each other, but the rotation direction of the cleaning roller 2 may be only one direction (that is, In the case where the conveyance direction of the cleaning target S is only one direction), the brush rollers 3A and 3B may be configured to rotate in the same direction.
- the brush roller may be constituted by one.
- the cleaning device 1A as shown in FIG. 5 The roller 3 rotates in the opposite direction to the cleaning roller 2 so that the brush roller 3 can efficiently scrape dust from the surface of the cleaning roller 2.
- the configuration of the cleaning device 1A as shown in FIG. 5 the cost of the device can be further reduced by simplifying the configuration of the device.
- a configuration in which three or more brush rollers are used may be employed.
- the case where the brush rollers 3A and 3B having substantially the same length as the cleaning roller 2 are used has been described.
- a plurality of brush rollers having a shorter length (for example, about half) than the cleaning roller 2 may be employed and disposed at positions shifted in the axial direction of the cleaning roller 2. According to this form, the cost of parts can be reduced by using a short brush roller, and the structure can be made compact.
- the cleaning device 1 is disposed below the cleaning target S, and the lower surface of the cleaning target S is cleaned.
- the cleaning device 1 is disposed below the cleaning target S, and the lower surface of the cleaning target S is cleaned.
- the cleaning device 1A is disposed on the lower side of the object to be cleaned S
- the cleaning device 1B is disposed on the upper side
- the upper and lower surfaces of the object to be cleaned S are simultaneously cleaned. May be configured.
- the cleaning rollers 2 are disposed on the upper and lower surfaces of the upper surface of the object to be cleaned S and the lower surface of the object to be cleaned S, so that dust present on both the upper and lower surfaces of the object to be cleaned S can be simultaneously removed with a single operation. Therefore, it is possible to provide the cleaning device 1C with extremely high work efficiency.
- the cleaning roller 2 When the cleaning device is disposed on the upper side of the object to be cleaned S like the cleaning device 1B, the cleaning roller 2 is provided so that the upper surface can be appropriately pressed according to the shape of the surface of the object to be cleaned S. It is preferable to have a configuration that can swing up and down.
- the frame unit 10 as a whole can swing up and down, or a rotation support mechanism (not shown) that allows the cleaning roller 2 to swing along an arc is separately provided in the frame unit 10.
- a configuration in which the cleaning roller 2 is rotated (swinged) in the vertical direction around the rotation shaft of the support mechanism may be employed.
- the mounting position of the blade 5 is not limited to the position shown in FIG. 4, and is arranged at a position suitable for scraping dust from the metal roller 4 in consideration of the structure of the frame unit 10 and the like. It is desirable to do.
- a cleaning device that removes dust from a substrate that is often used for mounting a semiconductor device such as a glass substrate, a printed circuit board, a film, a sheet, or a plastic plate, and can be widely used in the field of semiconductor devices.

Description
ここで、前記ブラシ体が複数個装備されている形態とは、前記クリーニングローラと略同じ長さの前記ブラシ体が複数個装備されている形態だけでなく、前記クリーニングローラよりも短い(例えば、半分程度の)長さの複数の前記ブラシ体が、前記クリーニングローラの軸方向にずらされた位置に配設された形態なども含まれる。
例えば、複数のブラシ体が互いに同一方向に回転するように構成した場合、各ブラシ体の連れ回り方向に前記クリーニングローラを容易に回転させることが可能となる。一方、各ブラシ体が互いに逆方向に回転するように構成した場合、例えば、2本のブラシ体、各々の回転速度を同じ速度に設定すれば、前記クリーニングローラの回転を停止させる制御が可能となり、各ブラシ体の回転速度を異なる速度に設定することで、前記クリーニングローラを所望の方向へ回転させる制御も可能となる。
逆に、一方のブラシ体の回転速度が高速、他方のブラシ体の回転速度が低速に設定されると、前記クリーニングローラが一方のブラシ体の連れ回り方向に回転するように制御される。このように、被クリーニング体の搬送方向を、適宜切り換えることが可能となり、双方向の搬送が必要な搬送システムに対応させることができ、利便性の高い装置とすることができる。
また、ブラシローラ3Aとブラシローラ3Bとの回転速度を同じ速度に設定して、クリーニングローラ2の回転を停止させる制御も可能となっている。
例えば、2の倍数のローラ(4本、6本など)をクリーニングローラ2に対して左右対称に配設し、右側の複数のブラシローラ群と、左側の複数のブラシローラ群とで、これらブラシローラ群を互いに逆方向に回転するように構成することで、上記と同様な制御を行うことができる。この場合は、左右のブラシローラ群に対応する金属ローラを適宜配設(増設)することが好ましい。
また、逆にブラシローラを3本以上使用した構成とすることもできる。
