Description

Optical film storage box and carrying cart of the storage box

The present invention relates to a storage box for stacking and storing a plurality of optical films, and a transport cart for transporting a plurality of storage boxes, which supports an optical film using a holder that is easy to operate and easily removable in the storage box. To stably transport the plurality of holders.

In general, LCD film types can be classified into polarizing film, diffuser film, reflecting film, and prism film. Optical films used in liquid crystal display devices are expected to increase due to increased shipments of LCD-TV. Keeping up.

Optical films are made of products through manufacturing processes such as tensile, extrusion, surface coating, lamination, and cutting to impart functionality to the resin film. Such an optical film is usually manufactured through several processes of overlapping a special film, and when the work is completed in one unit process, the optical film is placed in a storage box for the inter-process movement to be followed by a subsequent process.

Conventionally, the optical film is transported using a coverless box, but a lot of work and manpower is required due to the additional process of packaging to exclude the influence of foreign matter or moisture, and the film during the packaging process. There were difficulties in handling such as scratches or breakage on the surface.

In view of this problem, a packaging case for covering an optical film with a cover has been developed.

As such prior art, Korean Patent No. 10-0867966 entitled "Polarizing Film Packaging Case" includes a lid for installing a holder on which a polarizing film is mounted in a housing and sealing the housing. The holder has a plurality of sliders assembled to be movable left and right, and fixed according to the size of the polarizing film, forming a pressing member on the upper surface of the polarizing film, covering the lid thereon and assembling with the locking projections of the enclosure using a locking portion formed on the outer peripheral surface. Done. At this time, the sealing ring formed on the lower outer circumferential surface of the lid applies a coupling structure that blocks the air and the outside air inside the enclosure by pressing the uppermost part of the enclosure.

However, the prior art adopts a structure in which a slider is coupled to a cradle, and a work process of forming a plurality of grooves in a cross-shaped single cradle body for installing a plurality of sliders for aligning the film sides is required. In addition, since the cradle is not integrally formed in the enclosure and fits into the groove formed in the bottom of the enclosure, the cradle is suitable for preventing the shake of the cradle in the horizontal direction, but it is difficult to suppress the flow in the vertical direction. In other words, if the weight of the film loaded on the upper surface of the cradle is enough, it can be pressed, but it is vulnerable to being lifted in the vertical direction when an external force is applied due to a collision or the like during the transfer process. Accordingly, in the prior art, a pressing member for fixing the mounted polarizing film in the vertical direction should be additionally provided, and if the laminated film height is changed, the pressing member having a thickness corresponding thereto should be selectively applied. Of course, the pressure member may be made of an elastic material to fill the empty space in the upper part in a certain range, but when the loaded film is low and the empty space is large, the pressing force does not reach the upper part of the film, making it vulnerable to shaking. In addition, there is a disadvantage in that the fixed position of the slider in contact with the film side cannot be changed because the slider is fixedly installed at a predetermined position.

As described above, a large number of packaging cases are required in order to manufacture a large amount of optical film and smoothly proceed to a subsequent process, and the prior art generally includes a packaging case including a lid coupled to the enclosure to block external air. Due to the complexity and many of the components, the manufacturing cost of the packaging case increases. In addition, a locking component must be provided in the lid and the enclosure, respectively, to tightly couple the lid and the enclosure.
