The present invention relates to an apparatus for manufacturing a superfine fiber roll wiper for a cleanroom, and more particularly, to an apparatus for manufacturing a superfine fiber roll wiper for a cleanroom, in which a thermal cutting unit including thermal cutting blocks and thermal cutters is applied to a thermal cutting part, such that a process of manufacturing a roll wiper and a process of thermally bonding both ends of the manufactured roll wiper may be performed by the single apparatus, as a result of which, with the use of the single apparatus, it is possible to considerably improve workability, implement the mass-production, and reduce manufacturing costs, and in which the thermal cutting unit further including interval adjustment blocks in addition to the thermal cutting blocks and the thermal cutters is applied, such that a width of a roll wiper to be manufactured may be selectively and conveniently adjusted when a change in width of the roll wiper is required, as a result of which it is possible to manufacture roll wipers having various widths by using the single apparatus.
In general, a cleanroom or clean room (hereinafter, referred to as the “cleanroom”) refers to a room in which a clean and sterile state is maintained. The cleanroom is provided as a place in which processes of manufacturing, inspecting, storing, and cleaning semiconductor wafers, devices, components, precise devices such as semiconductors, TFTs, LCDs, and cutting-edge electronic devices, and precise products. The cleanroom is required to have a very clean environment in which there is no dust in a space.
For example, during the processes performed in the controlled cleanroom, a wiper dedicated for a cleanroom is used to remove debris produced during the manufacturing process, wipe surfaces of various devices and components in the cleanroom or wipe a wall surface of the cleanroom and other surfaces in the cleanroom.
The wiper for a cleanroom is made of fibers or non-woven fabrics which are excellent in adsorbing dust particles or moisture and may inhibit the generation of dust during the use of the wiper. The wiper is manufactured and used in the form of a roll wiper made by circularly winding a wiper having a predetermined width or in the form of a rectangular wiping wiper.
In this case, the roll wiper in the related art is used to make the rectangular wiping wiper by cutting the roll wiper by using a portable roll wiper cutting device or make multiple wiping wipers by using a separate transverse cutting device.
An apparatus for manufacturing the roll wiper unwinds and conveys a large width raw fabric from a winding roll, performs thermal bonding, by using an ultrasonic device, on the large width raw fabric for each width in a width direction orthogonal to a longitudinal direction, cuts the thermally bonded portion by using a separate heating cutter, winds again the cut raw fabrics around multiple winding rolls so that the cut raw fabrics are wound in the form of rolls having predetermined widths at a predetermined interval in the longitudinal direction of the roll, and then cuts the multiple winding rolls between the multiple roll wipers wound in the form of a roll, thereby manufacturing the multiple roll wipers.
The roll wiper is finally and completely manufactured after the roll wiper manufactured through the above-mentioned processes is further manually subjected to thermal bonding at both ends in a width direction by using an ultrasonic device.
However, according to the apparatus for manufacturing a roll wiper in the related art, the ultrasonic device and the heating cutter need to additionally perform the thermal bonding process on both ends in the width direction of the raw fabric manufactured as the roll wiper to be used as the roll wiper, and the cutting process between the thermally-bonded portions. Because the separate devices are used to manufacture the roll wiper, there is a problem in that working time is increased, and workability significantly deteriorates. For this reason, there is a problem in that it is difficult to implement the mass-production, a number of people are required to operate the separate devices, and manufacturing costs are increased as the separate devices are used.
Further, the apparatus for manufacturing a roll wiper in the related art cuts the large width raw fabric to a fixed single width in the width direction, and as a result, there is a problem in that it is difficult to selectively manufacture roll wipers having various widths and efficiency in manufacturing the roll wiper deteriorates.
There is a need for research and development on an apparatus for manufacturing a roll wiper, in which a process of manufacturing a roll wiper and a process of thermally bonding both ends of the manufactured roll wiper may be performed by the single apparatus, as a result of which, with the use of the single apparatus, it is possible to considerably improve workability, implement the mass-production, and reduce manufacturing costs, and in which a width of a roll wiper to be manufactured may be selectively and conveniently adjusted when a change in width of the roll wiper is required, as a result of which it is possible to manufacture roll wipers having various widths by using the single apparatus.

To this end, the large width raw fabric alignment adjustment part 700 broadly includes horizontal movement wheels 710, a lower end connection frame 720, a lower protrusion frame 730, a guide rod 740, a lower connection frame 750, a central installation frame 760, horizontal movement guide bars 770, and a horizontal movement cylinder 780.
In more detail, the horizontal movement wheels 710 are installed at front and rear sides of the lower ends of the pair of installation boxes 300a having the space therebetween in which the thermal cutting part 400, the first small width raw fabric winding part 500, and the second small width raw fabric winding part 600 are installed.
In addition, both ends of the lower end connection frame 720 are connected and fixed to the inner surfaces of the lower ends of the pair of installation boxes 300a.
Further, the lower protrusion frame 730 protrudes while having a “U” shape angled outward from a center of the lower end connection frame 720.
In addition, both ends of the guide rod 740 are fixedly installed in the form of a rod between brackets installed at both sides of the lower end connection frame 720 and spaced apart from each other at a predetermined distance.
Further, the lower connection frame 750 connects front lower ends of the pair of installation frames 300a having the horizontal movement wheels 710 at the lower end constituting the large width raw fabric supply part 100.
In addition, the central installation frame 760 extends rearward at a rear side spaced at a predetermined distance from a center to both sides of the lower connection frame 750.
Further, rear ends of the horizontal movement guide bars 770 are fixed at both front sides of the lower connection frame 750, and the ends of the horizontal movement guide bars 770, which extend forward by a predetermined distance, are restrictively connected to the guide rod 740 so as to be movable horizontally.
In addition, the horizontal movement cylinder 780 includes a cylinder 781 seated and installed on an upper portion of a protruding end of the lower protrusion frame 730 protruding from a center of the lower end connection frame 720, and rods 782 connected to surfaces of the central installation frame 760, which extend from the lower connection frame 750 and disposed opposite to each other, and protruding from both sides of the cylinder 781.
That is, the horizontal movement cylinder 780 may be a bidirectional horizontal moving type cylinder to which the pair of rods 782 is applied.
In addition, although not specifically illustrated, the apparatus for manufacturing a superfine fiber roll wiper for a cleanroom according to the present invention configured as described above may further include a control unit (not illustrated) embedded in the form of a control panel in a upper front surface of any one of the pair of installation boxes 300a having the space therebetween in which the thermal cutting part 400, the first small width raw fabric winding part 500, and the second small width raw fabric winding part 600 are installed. In other words, the control unit (not illustrated) may control the large width raw fabric supply part 100, the tension adjustment part 200, the large width raw fabric alignment detection part 300, the thermal cutting part 400, the first small width raw fabric winding part 500, the second small width raw fabric winding part 600, and the large width raw fabric alignment adjustment part 700.
According to the apparatus for manufacturing a superfine fiber roll wiper for a cleanroom according to the present invention configured as described above, the thermal cutting unit including the thermal cutting blocks and the thermal cutters is applied to the thermal cutting part, such that the process of manufacturing a roll wiper and the process of thermally bonding both ends of the manufactured roll wiper may be performed by the single apparatus, as a result of which, with the use of the single apparatus, it is possible to considerably improve workability, implement the mass-production, and reduce manufacturing costs.
Further, the thermal cutting unit further including the interval adjustment blocks in addition to the thermal cutting blocks and the thermal cutters is applied, such that a width of a roll wiper to be manufactured may be selectively and conveniently adjusted when a change in width of the roll wiper is required, as a result of which it is possible to manufacture roll wipers having various widths by using the single apparatus.
While the specific exemplary embodiment of the present invention has been described in detail above, the present invention is not limited to the specific exemplary embodiment, and the present invention can be variously modified by those skilled in the art, and the modifications belong to the scope of the present invention.
