Description

Glass substrate conveying structure

The present disclosure relates to a cassette, an adaptor, and a structure for transporting a glass substrate, and a method of using the same to transport a glass substrate.

Glass substrates are used in a variety of applications, such as display devices, construction, vehicles, photovoltaic cells, and the like. The glass substrate can be manufactured by melting a glass raw material and processing the molten material into a shape of a substrate. When it is necessary to transport the manufactured glass substrate from the manufacturer to the purchaser according to the purchase order, in order to reduce the transportation cost, the stacked glass substrates are packaged and transported together in a single glass substrate conveying structure.

Fig. 13 is a perspective view schematically showing a glass substrate transport structure 400 of the prior art (U.S. Patent No. 8,915,367).

As shown in Fig. 13, the stacked glass substrates are packaged in the transport structure 400 in an inclined position for transport.

In order to protect the glass substrate, paper sheets are inserted between the glass substrates.

However, in view of the following points, it is necessary to improve the glass substrate transport structure 400 of the prior art.

First, since the stacked glass substrates are packaged in an inclined position, the weight of the glass substrate is applied to the paper sheets. The applied weight causes friction between the glass substrate and the paper sheet, causing the particles to fall off the paper sheet.

Therefore, in order to remove the particles, an acid cleaning operation is required. The cleaning operation itself is an operation that leads to time and cost. Further, since the cleaning operation must be performed after the completion of the conveyance, in most cases, the cleaning operation is performed by the party purchasing the glass substrate. The cleaning operation is required by the customer to complain about the glass substrate manufacturer.

In addition, the friction between the paper sheet and the glass substrate reduces the surface quality (scratches, stains, etc.) of the glass substrate.

In addition, the weight of the front side glass substrate in the stacked glass substrates stacked on each other is cumulatively applied to the rear side glass substrate. Since the weight concentration of the glass substrate is uneven, the quality of the front substrate is different from the quality of the rear substrate.

Further, the glass substrate transport structure 400 of the prior art occupies a relatively large area. For example, when such a glass substrate transport structure 400 is shipped on or in a loading area of a transport vehicle, the number of single transportable glass substrates is limited. It creates the disadvantage of higher logistics costs.

This disadvantage becomes more pronounced as the transport distance increases.

The information disclosed in this Background section is only a preferred understanding of the background and is not to be construed as an admission

Patent Document 1: US Patent No. 8,915,367

The various aspects of the present disclosure are directed to reducing the amount of particles.

It is also intended to remove the need for cleaning operations that utilize acid to remove particles.

It is also intended to avoid lowering the surface quality of the glass substrate during transport.

It is also intended to avoid differences in surface quality between a plurality of glass substrates.

It is also designed to reduce logistics costs.

According to one aspect, a cassette for encapsulating a plurality of glass substrates includes: a bottom cover covering a bottom surface of the stacked glass substrate; and a back cover covering the back surface of the stacked glass substrate. The inner surface of the bottom cover facing the stacked glass substrate and the inner surface of the back cover are perpendicular to each other.

According to another aspect, a receptacle includes: a bottom frame having a bottom surface of a cassette in which a stacked glass substrate is packaged; and a back frame coupled to the bottom frame to support a back surface of the cassette. The front surface of the back frame facing the cassette forms a vertical surface, and the top surface of the bottom frame facing the cassette forms a horizontal plane.

According to still another aspect, a glass substrate transport structure includes: a cassette in which a stacked glass substrate is packaged; and a receptacle in which a cassette on which a stacked glass substrate is packaged is mounted. The cassette is a separate body that is separable from the adapter.

According to another aspect, a glass substrate transport method includes: a first operation of mounting a cassette in which a stacked glass substrate is packaged in an inclined position on a first tilt receiver; and clamping the first tilt adapter A second operation of separating and transporting the cassette on at least one of the ground transport vehicle, the marine vehicle, and the air transport vehicle, wherein the cassette is transported in a vertically mounted position.

The second operation may include separating the cassette from the first tilting receptacle, mounting the cassette to the vertical receptacle, and transporting the vertical receptacle on which the cassette is mounted on the vehicle.

The second operation may include separating the cassette from the first tilting receptacle, carrying the cassette on the vehicle, and securing the cassette to the vehicle by the guiding tool to place the cassette in a vertical position and transport the cassette . Additionally, the second operation can further include unloading the cassette from the vehicle and mounting the cassette to the frame in a vertical position and mounting the cassette in a vertical position on the frame for storage.

The glass substrate transport method may further include a third operation of unloading the cassette from the vehicle and attaching the cassette to the second tilt receiver in an inclined position.

According to the present disclosure, it is desirable that the weight of the glass substrate is not applied to the sheet inserted between the glass substrates, thereby significantly reducing the friction between the glass substrate and the sheet. Therefore, the amount of particles falling off the sheet can be significantly reduced.

In addition, the need for a cleaning operation using acid to remove particles can be removed.

Furthermore, the surface quality of the glass substrate can also be improved by reducing the friction between the glass substrate and the paper sheet.

Further, ideally, the weight of one of the plurality of glass substrates is not applied to the other glass substrate of the plurality of glass substrates, so that uneven concentration of the weight of the glass substrate can be prevented. Therefore, the surface quality of a plurality of glass substrates can be maintained to be uniform.

Furthermore, more cassettes can be carried in the carrying area of the same container or the same vehicle, which can significantly increase the amount of single shipment. Therefore, the logistics cost can be significantly reduced.

Other features and advantages of the present invention will be apparent from the accompanying drawings, and in the <RTIgt; It will be apparent from the following detailed description of the <RTIgt;

The illustrative embodiments of the present disclosure, which are illustrated in the accompanying drawings, and which are described below, are to be understood by those of ordinary skill in the art.

In this document, reference should be made to the drawings, wherein the same reference numerals and In the following description, the detailed description of the application of the present disclosure will be omitted in the case of the detailed description of the known functions and components incorporated herein.

1 is a perspective exploded view schematically illustrating a package structure in which a stacked glass substrate G is packaged in a cassette 200, according to an exemplary embodiment.

The stacked glass substrate G is packaged in the cassette 200. The cassette 200 includes at least a bottom cover 211 and a back cover 213. In the embodiment shown in FIG. 1, the cassette includes a side cover 212, a front cover 217 and a top cover 216 in addition to the bottom cover 211 and the back cover 213.

The bottom surface, the back surface, the side surface, the front surface, and the top surface of the stacked glass substrate G are covered with a bottom cover, a back cover, a side cover, a front cover, and a top cover. The bottom surface, the side surface, and the top surface of the stacked glass substrate G are surfaces formed by the bottom surface, the side surface, and the top surface of a plurality of glass substrates connected to the standing position.

The bottom cover 211, the back cover 213, and the side cover 212 may be integrally provided, thereby forming the housing cover 214. The front cover 217 and the top cover 216 as separate parts may be coupled to the housing cover 214.

The inner surface of the bottom cover 211 facing the stacked glass substrate G and the inner surface of the back cover 213 may be perpendicular to each other. Further, even if the weight of the stacked glass substrate G is applied, and the back cover 213 is in the vertical position and the back cover 213 is in the inclined position, the cover back 213 and the bottom cover 211 are perpendicular to each other. Therefore, the back cover 213 and the bottom cover 211 are required to have a stiffness that can withstand the weight of the stacked glass substrate G.

The bottom pad 231 can be inserted between the bottom cover 211 and the stacked glass substrate G. The back pad 233 can be inserted between the back cover 213 and the stacked glass substrate G. The back pad 233 may include a Paulownia piece 233a and a polyvinyl chloride (PVC) piece 233b which are sequentially disposed from the front. The front pad 237 is disposed between the front cover 217 and the stacked glass substrate G.

The front cover 217 may include a lattice member 217a. The lattice member 217a can be in close contact with the stacked glass substrate G (via the front pad 237) so that the stacked glass substrate G can be more stably fixed. It can thus limit the movement of the stacked glass substrate G, thereby further reducing the amount of particles that fall off from the sheet.

FIG. 2 is a perspective view schematically depicting a slanted receptacle 310 in accordance with an exemplary embodiment.

The tilt adapter 310 shown in FIG. 2 depicts the bottom frame 311 and the back frame 313. The bottom surface of the cassette 200 in which the stacked glass substrates G are packaged is positioned on the bottom frame 311. The back frame 313 is coupled to the bottom frame 311 to support the back surface of the cassette 200. The tilt adapter 310 of FIG. 2 can further include a base frame 315. The base frame 315 serves as a base for fixing the back frame 313 and the bottom frame 311.

The front surface of the back frame 313 facing the cassette 200 forms an inclined surface with respect to the vertical surface. (In the present disclosure, the term "surface" is not limited to a geographically perfect surface, but includes an imaginary surface formed by the surface of the frame connecting the second figure. The top surface of the back frame 313 facing the cassette 200 forms an inclined surface with respect to the horizontal surface. Therefore, the cassette 200 in which the stacked glass substrates G are packaged is mounted on the tilt receiver 310 in an inclined position.

FIG. 3 is a side view schematically depicting a vertical receptacle 320 in accordance with an exemplary embodiment.

The vertical adapter 320 shown in FIG. 3 includes a bottom frame 321 and a back frame 323. The bottom surface of the cassette 200 in which the stacked glass substrates G are packaged is positioned on the bottom frame 321. The back frame 323 is coupled to the bottom frame to support the back surface of the cassette 200.

The vertical adapter 320 of FIG. 3 may further include a front front frame 327 that supports the cassette 200. The vertical adapter 320 may further include a fixing portion 329 that fixes the front frame 327 to the back frame 323. The front frame 327 prevents the cassette 200 from slipping forward.

A front surface of the back frame 323 facing the cassette 200 forms a vertical surface. The top surface of the bottom frame 321 facing (ie, supporting) the cassette 200 forms a horizontal plane. Therefore, the cassette 200 in which the stacked glass substrates G are packaged is vertically mounted on the vertical receptacle 320. Preferably, the rear surface of the front frame 327 facing the cassette 200 forms a vertical surface.

The vertical receptacle 320 (back frame 323) includes a body and a strap 323a. The main body supports the cassette 200, and the strap 323a fixes the cassette 200 by coupling the cassette 200 to the main body (refer to Fig. 5).

The adapter may be one selected from the oblique adapter 310 of Fig. 2 and the vertical receptacle 320 of Fig. 3. The adapter can be replaced with a vertical adapter 320 from the tilt adapter 310 as needed, or vice versa.

The tilt adapter 310 allows the glass substrate to be easily carried and unloaded. That is, the glass substrate can be easily supported on the bottom frame and the back frame without the need to worry about carrying and unloading at a position where the front slides down. The cassette 200 can be coupled to the tilt adapter 310 by a bolt tool. In contrast, the vertical adapter 320 facilitates the transport of the glass substrate. The vertical receptacle 320 allows the glass substrate to be transported in a vertical position. Therefore, it can achieve the objects of the present disclosure, such as reducing particles, removing the need for a cleaning operation, preventing degradation of the surface quality of the glass substrate, and preventing a difference in quality between the glass substrates. In this manner, the present disclosure features two advantages of using two types of adapters.

Alternatively, a universal adapter can be used instead of the vertical adapter 320 to replace the tilt adapter 310, and vice versa. The universal adapter has an inclined position in which the cassette 200 is installed in an inclined position and a vertical position in which the cassette 200 is mounted in a vertical position.

In this regard, for example, the axis of rotation may be provided at a position where the bottom frame abuts the back frame such that the bottom frame and the back frame are rotatable from a vertical position to an inclined position about the axis of rotation and vice versa (however, it should be understood that The disclosure is not limited to this). In order to change the position of the back frame and the bottom frame, the adapter may further comprise a drive tool such as a motor. Alternatively, the drive tool can apply a force to push or pull the separate device of the back frame. In addition, the adapter may require a securing means for securing the position of the back frame and the bottom frame.

The structure of Fig. 4 can look similar to the structure of Fig. 13. However, the structures of Figs. 4 and 5 are different from those of Fig. 13. Specifically, the structures of FIGS. 4 and 5 are configured such that the cassette 200 and the adapter are provided by separate bodies that are separable from each other, and the structure of FIG. 13 is configured to correspond to the portion of the cassette 200 and corresponding to the receiving. The parts of the unit are provided as a single unit.

In accordance with the disclosed structure, the cassette 200 can be separated from the receptacle without changing the package structure in which the plurality of glass substrates are packaged. The package structure indicates a structure in which the bottom surface and the back surface of the stacked glass substrate are perpendicular to each other.
