Description

Roller type cleaner used in cleanrooms {Roller type cleaner used in cleanrooms}

The present invention relates to a roller-type cleaner used in a clean room, and more particularly, to a roller-type compact cleaner used for cleaning electronic devices such as display devices in a clean room.

In real life such as home and workplace, cleaning tools are used to remove various foreign substances such as dust, hair, and lint.

Various types of cleaning tools can be used depending on the cleaning target. In general, a cleaning cloth (or tape) is wound around a pair of rollers. Contaminated cloth forms a winding structure. To this end, the pair of rollers can be divided into a supply roller and a take-up roller that interlock with each other, and a separate operation module is provided inside so that the operation of the operation module unwinds the cloth from the supply roller and simultaneously winds it on the take-up roller. Such a roller-type cleaning tool is made in such a way that a cartridge is replaced with a roller, so there is convenience in not having to wash contaminated cloth.

However, such a conventional roller-type cleaning tool is provided with an operation module for operation therein and has a complicated structure, and thus has a disadvantage in that miniaturization is impossible. In addition, in the conventional roller-type cleaning tool, the contaminated surface is exposed to the outside as it is, and dust or contaminants adsorbed to the cloth are separated and there is a risk of contaminating the surroundings again.

In particular, various electronic devices such as display devices are inspected and cleaned in a clean room where a high level of cleanliness is maintained. In this way, when the display device is to be cleaned, the cleaning tool must be miniaturized, contaminants must not be generated from the cleaning tool, and the cleaning tool must not damage the display device. However, conventional cleaning tools exhibit very unfavorable limitations in miniaturization, re-contamination and safety problems for use inside a clean room.

Referring to these drawings, the cleaner of this embodiment includes a pair of main frames 100 spaced apart from each other, a pair of handle plates 200 coupled to the main frame while facing each other in the central region of the main frame, and a main frame It includes a pair of driving rollers 300 coupled to the main frame at both ends thereof, and a cleaning member 400 having both ends wound around the driving rollers while passing through the inside of the pair of handle plates.

The main frame 100 is a component that forms the skeleton of the cleaner, and an end portion of the frame having a predetermined length may be bent to one side to form a 'c' shape. The main frame 100 may be divided into a plate coupling area for coupling the handle plate 200 and a roller coupling station for coupling the driving roller 300 by bending both ends of the plate coupling region in a vertical direction on one side. . The main frame 100 is composed of a pair of first and second main frames 100-1 and 100-2 facing each other, and both ends are disposed in a direction facing each other to form a 'ㅁ'-shaped frame frame. .

In addition, the main frame 100 may have a cross section of various shapes such as a circular shape and a polygonal shape, and preferably has a circular shape so that the handle plate 200 and the driving roller 300 described later can be easily coupled and rotated. In addition, the plate coupling area and the roller coupling area of the main frame 100 each have a predetermined length, and may have an appropriate length in consideration of the width of the handle plate 200 and the length of the driving roller 300 .

The handle plate 200 shields the cleaning member 400 wound along the pair of driving rollers 300 from the outside, guides the movement of the cleaning member 400, and at the same time provides a handle function so that the user can easily use the cleaning member 400. do. The handle plate 200 is composed of a plate having a predetermined width and length, and one side edge of the plate is formed with a first coupling part 210 for coupling to the first main frame 100-1, and the other side A second coupling part 220 for coupling to the second main frame 100-2 is formed at the edge. The handle plate 200 is composed of a pair of first and second handle plates 200-1 and 200-2 facing each other.

In addition, the first coupling part 210 formed on the handle plate 200 may form a hinge structure. Therefore, while the hinges of the first handle plate 200-1 and the hinges of the second handle plate 200-2 form a shape that matches each other, the first and second handle plates 200-1 and 200-2 are connected to the first main frame. Hinge to (100-1). Accordingly, the first and second handle plates 200-1 and 200-2 may be folded or unfolded side by side while facing each other with the first main frame 100-1 as an axis.

In addition, the second coupling part 220 formed on the handle plate 200 is coupled to the second main frame 100-2 in a folded state so that the first and second handle plates 200-1 and 200-2 face each other, and , A locking means (not shown) may be formed in the second coupling part 220 of the first and second handle plates 200-1 and 200-2 to fix their coupling. For example, the locking means may be composed of a locking hook and a locking groove having a structure that conforms to each other.

The first coupling part 210 and the second coupling part 220 are coupled while surrounding the first main frame 100-1 and the second main frame 100-2, respectively. Therefore, the handle plate 200 can flow along the longitudinal direction using the first and second main frames 100-1 and 10-2 as guide rails. The handle plate 200 can change its position to a predetermined length, and presses the cleaning member 400 wound around the driving roller 300 in close proximity to the driving roller 300 on either side, thereby driving the driving roller 300 during use. ) can be prevented from rotating regardless of the user's will.

In addition, the handle plate 200 is provided with a guide protrusion 230 for guiding the movement of the cleaning member 400 when the cleaning member 400 is wound from the driving roller 300 on one side to the driving roller 300 on the other side. do. The guide protrusion 230 is formed long in the longitudinal direction of the handle plate 200, that is, in the moving direction of the cleaning member 400. The guide protrusion 230 guides the cleaning member 400 to move in the longitudinal direction and prevents the cleaning member 400 from moving in the width direction at the same time, so that the cleaning member 400 can be wound at an accurate position on the driving roller 300 on the other side.

In addition, as shown in FIG. 2, the guide protrusion 230 formed on at least one side of the first and second handle plates 200-1 and 200-2 is divided into a plurality of discontinuous parts along the longitudinal direction, and the end It forms a wedge shape pointing in the direction of travel. The wedge-shaped guide protrusion 230 guides the cleaning member 400 to move only in one direction and prevents it from being wound in the reverse direction.

The driving roller 300 supplies the cleaning member 400 from one side to the other, and is composed of a pair of first and second driving rollers 300-1 and 300-2. The cleaning member 400 is wound by moving from the first driving roller 300-1 on one side to the second driving roller 300-2 on the other side. Therefore, the first driving roller 300-1 functions as a supplying roller for supplying clean unused cleaning members 400, and the second driving roller 300-2 serves as a take-up roller for winding the used cleaning member 400. function as

The driving rollers 300 are spaced apart from each other by a predetermined interval with the knob plate 200 interposed between both ends of the first and second main frames 100-1 and 100-2, that is, in the roller coupling area. Accordingly, the cleaning member 400 wound around the first driving roller 300-1 is wound around the second driving roller 300-2 while passing between the first and second handle plates 200-1 and 200-2.

In addition, the driving roller 300 has a cylindrical shape while both end portions 310 have a predetermined curvature and are gently curved. When cleaning an electronic device with a display panel or the like using a cleaner, the driving roller 300 may impact the display panel. When the end of the driving roller 300 has a gentle curvature, damage to the display panel due to such an impact can be minimized or prevented.

At this time, the cleaning member 400 is configured to be reversely wound around the first driving roller 300-1 and the second driving roller 300-2. That is, as shown in FIG. 2 , the cleaning member 400 is wound so that the outer surface of the first driving roller 300-1 forms the inner surface of the second driving roller 300-2.

Contaminants adsorbed on the cleaning member 400 may be separated again due to a user's touch for operating the driving roller 300 . However, since the surface of the cleaning member 400 adsorbing contaminants is wound inward on the second driving roller 300-2 by the structure in which the cleaning member 400 is wound in a reverse direction as in the present embodiment, the surface of the cleaning member 400 is wound toward the outside. not exposed Therefore, since the user touches the opposite surface (clean surface) of the cleaning member 400 to operate the second driving roller 300-2, it is possible to fundamentally prevent the adsorbed contaminants from being separated again, and the electronic device No recontamination of

In addition, according to the present invention, the cleaning member 400 absorbs contaminants from the first driving roller 300-1 and then moves to the second driving roller 300-2 along the inside of the pair of handle plates 200. It consists of Therefore, contaminants may be separated from the cleaning member 400 by an impact or the like during movement of the cleaning member 400, but since the separated contaminants are trapped inside the handle plate 200, re-contamination of the electronic device occurs due to the separation of the contaminants It doesn't work.

In addition, the roller type cleaner of this embodiment is configured to easily replace the roller cartridge (combination of the driving roller and the cleaning member) after use. To this end, a locking protrusion 110 is formed on the first main frame 100-1.

Referring to FIG. 4 , a locking protrusion 110 protruding in a vertical direction is formed on the inside of the first main frame 100-1, and the locking protrusion 110 is configured to be caught by the first coupling part 210. This allows the first main frame 100-1 to stand upright in the vertical direction while the pair of handle plates 200 are unfolded. To this end, a plurality of locking protrusions 110 are formed along the longitudinal direction of the first main frame 100-1, and each locking protrusion 110 is attached to the first coupling part 210 on both sides arranged in a zigzag structure. It is supported and maintains the first main frame 100-1 in a vertical direction. Therefore, since the first main frame 100-1 does not interfere with the handle plate 200 while the handle plate 200 is unfolded, the user can easily separate or assemble the roller cartridge from the first main frame 100-1. there is.

5 is a plan view showing a state in which the cleaning member, which is a main part of the cleaner according to the present embodiment, is unfolded, and FIG. 6 is a conceptual view showing a state in which the cleaning member of FIG. 5 is wound around a roller.

Referring to FIG. 5 , the cleaning member 400 of this embodiment has a trapezoidal shape with a narrow width w1 on one side and a relatively wide width w2 on the other side with respect to the entire longitudinal direction (w1 < w2). The narrow end of the cleaning member 400 is wound around the first driving roller 100-1 where cleaning is performed.

Accordingly, as shown in FIG. 6 , the cleaning member 400 starts to be wound around the first drive roller 100-1 from the end having a narrow width and is wound toward the outside with a relatively wide width. Accordingly, the cleaning member 400 ) covers the cut surfaces 410 on both sides of the inner cleaning member. In this way, the outer cleaning member 400 is configured to be wound while covering the cut surfaces 410 on both sides of the inner cleaning member 400, thereby minimizing contamination of the electronic device by foreign substances that may occur on the cut surface 410. , Prevent damage to electronic devices due to interference between the cutting surface 410 and electronic devices.

In addition, the cleaning member 400 is wound while being repeatedly overlapped with the first driving roller, and the cut surfaces 410 on both sides of the outer cleaning member 400 face the inner center. Therefore, when cleaning while the cleaning member 400 contacts the electronic device, both cutting surfaces 410 can be separated from the electronic device, preventing damage to the electronic device due to collision between the cutting surface 410 and the electronic device.
