Description

Glass cassette {GLASS CASSETTE}

The present invention relates to a glass cassette, and more particularly, to a glass cassette usable in both a cleaning process and an ion-enhanced process.

In general, glass remains in a molten potassium nitrate (KNO ₃ ) solution at a certain temperature or higher for a certain period of time, and ion substitution occurs at the surface, thereby increasing the surface strength. At this time, potassium nitrate is contained in a constant shape bath in a molten state, and the temperature of potassium nitrate is about 390 ° C or more.

On the other hand, the ion strengthening process largely consists of preheating, strengthening, and slow cooling processes. In consideration of productivity, several pieces of glass are fixed on a cassette having a specific shape, and the preheating bath, the reinforcing bath, and the slow cooling bath are circulated. At this time, a cleaning process is essentially added before and after the ion strengthening process for such glass. The purpose of the cleaning process is to remove foreign substances on the glass surface before reinforcement and to remove potassium nitrate remaining on the glass surface after reinforcement.

However, since the cleaning process is performed by ultrasonic cleaning, the cassette used in the cleaning process is formed of, for example, soft teflon, which is vulnerable to high temperatures. Therefore, in order to perform the ion-strengthening process after the cleaning process, the operator has to transfer several hundreds to several hundreds of cleaned glass from the cleaning-dedicated cassette to the ion-enhanced dedicated cassette.

In the case of a small product, since several tens to several hundred glass pieces are installed per batch, a separate operator is required for this, a time loss due to installation time is significant, and glass breakage is frequently caused by manual operation.

That is, conventionally, the cleaning-dedicated cassette and the ion-enhanced-dedicated cassette are separated, resulting in a lot of human, material, and time loss.

Hereinafter, a glass cassette according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

In the following description of the present invention, detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

1 to 3, a glass cassette 100 according to an embodiment of the present invention is configured to fix tens to hundreds of glass substrates 10 during an ion exchange treatment process, which is a chemical strengthening method for manufacturing tempered glass Is a jig. At this time, the glass substrate 10 may be a glass to be used as a cover glass for various mobile electronic devices after the tempering process, for example, a three-dimensional glass including a predetermined round shape.

The glass cassette 100 includes a first frame 110, a first support 120, a second support 130, a second frame 140, a third support 150, and a fourth support 160 .

The first frame 110 is a device for supporting a first support 120 and a second support 120 for fixing the glass substrate 10. The first frame 110 is formed to be attachable and detachable to the second frame 140. To this end, the first frame 110 may include a pair of first walls 111 and a first connecting rod 112. Each of the first walls 111 has a first support 120 for fixing the lower end of the glass substrate 10 and a second support 120 for fixing the lower end of the glass substrate 10 And is connected to both longitudinal ends of a second support 130 for fixing both ends. The first connecting rod 112 is formed between a pair of first walls 111 arranged opposite to each other to connect the first walls 111 with each other. Accordingly, the first frame 110 is formed in a substantially hexahedral shape. In order to facilitate the chemical strengthening process for the glass substrate 10 mounted on the inner side, that is, to facilitate the flow of the solution, It is preferable to have a structure that is open all but the minimum area for maintaining the skeleton and the connection relationship. At this time, the first connecting rod 112 may be omitted in some cases.

On the other hand, each of the pair of first walls 111 is formed with a slit 113 to which both end portions in the longitudinal direction of the second support base 130 are fastened. As shown in the figure, the second supports 130 support both side ends of the glass substrate 10, so that the slits 113 can be formed in the first wall 111 at the corresponding positions. At this time, the slit 113 is formed to be inclined toward the center of the first wall 111. The second support base 130 is positioned in the region of the slit 113 close to the central side of the first wall 111 by gravity and the region of the slit 113 is positioned on the glass substrate (10). When the first frame 110 is attached to or detached from the second frame 140, the slit 113 may be formed in the second frame 130, depending on the pressure applied to the second frame 130, And is in contact with the side end of the substrate 10 to support it or to separate it from the side of the glass substrate 10. The operation will be described in more detail below.

When the first frame 110 is attached to the second frame 140, a pressure is applied to each of the pair of first walls 111 so that the fourth support frame 160 installed on the second frame 140 moves. The action of the fourth support 160 through the protrusion 114 will be described in more detail below.

The first support 120 is installed inside the first frame 110. As shown in the figure, the first support rods 120 are provided in a pair, are arranged parallel to each other, and are fixed to the first wall body 111 having both longitudinal ends thereof facing each other. At this time, the first support 120 may be bolted or welded to the first wall 111. The first support 120 supports the lower end of the glass substrate 10, and a plurality of mounting grooves 121 are formed along the longitudinal direction to stably support the glass substrate 10. The mounting groove 121 may be formed along the circumference of the first support 120.

Accordingly, the first support 120 can support the number of the glass substrates 10 corresponding to the number of the mounting grooves 121. At this time, one first support 120 supports one side lower end of the glass substrate 10, and the other first support 120 supports the other lower end of the glass substrate 10, The mounting grooves 121 formed in the support base 120 should be formed in parallel with each other, that is, at positions corresponding to each other.

The first support 120 supports the glass substrate 10 in an ion-strengthening process at a temperature of about 390 ° C or higher, and therefore, it is preferable that the first support 120 is made of a stable material at a high temperature. For example, the first support 120 may be made of, for example, 304, 316 stainless steel.

The second support frame 130 is installed inside the first frame 110. As shown in the figure, the second support rods 130 are connected to the first wall 111, which is disposed in parallel with the first support wall 130 and is arranged parallel to the first support wall 130, Is inserted into the slit 113 formed in the slit 111. Accordingly, the second support 130 is located at the lowest area of the slit 113 formed in an inclined shape by the gravity when the slit 113 is inserted into the slit 113. When the glass substrate 10 is mounted on the slit 113, So that it comes into contact with its side. However, when the first frame 110 is mounted on the second frame 140, the second support frame 130 is moved away from the center of the first wall 111 by the pressure transmitted in the direction opposite to the gravity The contact with the glass substrate 10 is released. That is, the second support 130 is installed inside the first frame 110 so as to be detachable from both ends of the glass substrate 10.

Meanwhile, the pair of second supports 130 support both ends of the glass substrate 10, and a plurality of mounting grooves 131 are formed along the longitudinal direction to stably support the glass substrate 10 . The mounting groove 131 may be formed along the circumference of the second support 130.

Accordingly, the second support 130 can support the number of the glass substrates 10 corresponding to the number of the fixing grooves 131 formed. At this time, since the pair of second supports 130 support both ends of one glass substrate 10, the mounting grooves 131 formed on the respective second supports 130 are positioned at positions corresponding to each other Lt; / RTI > Since the bottom and both ends of one glass substrate 10 are supported by the fixing groove 121 of the first supporting base 120 and the fixing groove 131 of the second supporting base 130, The mounting groove 121 of the first supporting base 120 and the mounting groove 131 of the second supporting base 130 are also formed at positions corresponding to each other.

Like the first support 120, the second support 130 supports the glass substrate 10 in the ion-strengthening process at a temperature of about 390 ° C or higher. Therefore, it is preferable that the second support 130 is made of a stable material at a high temperature. For example, the second support 130 may be made of stainless steel, which is the same material as the first support 120.

The second frame 140 is a device for supporting the third support 150 and the fourth support 160 for fixing the glass substrate 10. The second frame 140 is formed such that the first frame 110 is mountable and detachable. To this end, the second frame 140 may include a pair of second walls 141 and a second connecting rod 142. Each of the second walls 141 has a third support 150 for fixing the lower end of the glass substrate 10 and a second support 150 for fixing the lower end of the glass substrate 10, And is connected to both longitudinal ends of a fourth support member 160 that fixes both ends. The second connecting rod 142 is formed between a pair of second walls 141 arranged to face each other to connect the second walls 141. At this time, in order to achieve a stable structure, a plurality of second connecting rods 142 may be formed. Accordingly, the second frame 140 has a substantially hexahedron shape. Like the first frame 110, the second frame 140 preferably has an open structure in which at most six faces are opened. Since the first frame 110 is mounted in the second frame 140, the second connecting rod 142 is relatively longer than the first connecting rod 112, and the size of the second wall 141 is also made longer 1 < / RTI >

On the other hand, a latch 143 and an elastic member 144 are formed on each of the pair of second walls 141. Here, since the pair of second walls 141 have the same structure, the description will be made with reference to one second wall 141 in the following description.

The latch 143 is formed on both sides of the second wall 141. In this case, when the first frame 110 is mounted on the second frame 140, when the projection 114 formed on the first wall 111 is lowered and caught in the second frame 140, As shown in FIG. In addition, the latch 143 is fastened to the longitudinal end of the fourth support base 160. Accordingly, when the latch 143 is rotated by the projection 114, the fourth support 160 connected to the latch 143 is moved toward the glass substrate 10, . At this time, when the first frame 110 is separated from the second frame 140, the fourth support member 160 must be separated from the side of the glass substrate 10. To this end, the elastic member 144 is connected to the latch 143. The elastic member 144 is elastically deformed when the latch 143 is rotated by the protrusion 114 and when the pressing force applied to the latch 143 by the protrusion 114 is removed, In the opposite direction, i.e., returns the latch 143 to its original position. The fourth support member 160 connected to the latch 143 also returns to its original position and moves away from the glass substrate 10 to be separated from the side edge of the glass substrate 10. The latch 143 and the elastic member 144 may be provided on both sides of the second wall 141 because two of the fourth supports 160 are provided on both sides.

Further, a guide hole 145 may be formed in the second wall 141. The guide member 145 guides the moving direction of the second support 130 protruding outside the first wall 111 when the first frame 110 is mounted on the second frame 140 . The guide member 145 may include a pair of protrusions spaced from each other by a distance corresponding to the diameter of the second support member 130, as shown in FIG. As the guide hole 145 is formed in this way, the first frame 110 can be mounted with respect to the guide hole 145, and when the first frame 110 is mounted on the second frame 140, Convenience can be improved. These guide holes 145 are formed on both sides of the second wall 141.

On the lower side of the guide hole 145, a right triangular-shaped sliding hole 146 having an inclined surface opposite to the slit 113 can be protruded. Accordingly, when the first frame 110 is mounted on the second frame 140, the second support frame 130 passes through the guide hole 145, The second support base 130 descends on the inclined surface of the sliding hole 146 and the slope of the slit 113 is lowered by the mounting pressure of the first frame 110, Is gradually moved away from the area in contact with the side edge of the glass substrate 10. [ When the first frame 110 is attached to the second frame 140, the second support base 130 is automatically separated from the side of the glass substrate 10 by the slit 113 and the sliding hole 146, do.

In addition, a pedestal 147 may be formed on both lower ends of the second wall 141. The pedestal 147 serves to prevent the first frame 110 from being separated from the second frame 140 when the first frame 110 is attached to the second frame 140, Thereby supporting the first wall 111. The coupling stability between the first frame 110 and the second frame 140 can be secured through the pedestal 146.

The third support 150 is installed inside the second frame 140. As shown in the figure, the third support rods 150 are provided in a pair, are arranged parallel to each other, and are fixed to the second wall 141 whose both ends in the longitudinal direction are disposed so as to face each other. At this time, the third support 150 may be bolted to the second wall 141. The third support 150 supports the lower end of the glass substrate 10 instead of the first support 120 when the first frame 110 is mounted on the second frame 140. The third support 150 is installed on the second wall 141 such that the third support 150 is relatively higher than the first support 120 when the first frame 110 is mounted on the second frame 140. In addition, the pair of third supports 150 are formed to be narrower than the width between the first supports 120 so as to be positioned between the pair of first supports 120. A pair of first supports 120 supporting the lower end of the glass substrate 10 when the first frame 110 is mounted to the second frame 140 in the downward direction are supported by a pair of third supports 150 The lower end of the glass substrate 10 is supported naturally by the third support 150 and the first support 120 is moved from the lower end of the glass substrate 10 Separated.

In order to stably support the lower end of the glass substrate 10, a plurality of mounting grooves 151 are formed in the third support base 150 along the longitudinal direction. The mounting groove 151 may be formed along the circumference of the third support 150.

The third support 150 can support a plurality of glass substrates 10 through the plurality of mounting grooves 151. Like the first support 120 and the second support 130, The first frame 110 may be mounted on the second frame 140 at a position corresponding to each of the first and second support rods 151, Since the glass substrate 10 is received from the first support base 120, it must be formed at a position corresponding to the mounting groove 121 of the first support base 120. The correspondence relationship between the positions of the support grooves 121, 131 and 151 formed on the support rods 120, 130 and 150 is the same as that of the support rods 161 formed on the fourth support rods 160 do.

The reason for moving the glass substrate 10 supported by the first support 120 to the third support 150 in the embodiment of the present invention is that the glass substrate 10 is attached to the first support 120 made of stainless steel, The generated vibration is transferred to the glass substrate 10 and the glass substrate 10 is also vibrated with a certain amplitude. Due to this shaking, When the substrate 10 is struck on the first support 120 made of stainless steel having a high hardness, the glass substrate 10 is repeatedly subjected to a minute impact repeatedly by the first support 120, This is because the substrate 10 may be damaged.

Accordingly, it is preferable that the third support 150 is made of a soft material having a low hardness that does not damage the glass substrate 10 even if the glass substrate 10 is supported during the cleaning process. In an embodiment of the present invention, the third support 150 may be made of a fluorine-based resin. For example, the third support 150 may be formed of any one of fluorine resins such as polytetrafluoroethylene (PTFE), perfluorinated acids (PFA), ethylene tetrafluoroethylene (ETFE), polyvinylidene fluoride (PVDF), polyvinyl fluoride (PVF), and polyetheretherketone It can be done in one.

The fourth support frame 160 is installed inside the second frame 140. As shown in the figure, the fourth support rods 160 are connected to the second wall 141, which are arranged in parallel with each other, and whose opposite ends are longitudinally opposite to each other. The fourth support frame 160 is operatively installed according to the pressure applied by the first frame 110 when the first frame 110 is mounted on the second frame 140. That is, the fourth support base 160 is connected to the rotating clasp 143 by the pressure applied from the protrusion 114 of the first wall body 111 so that the descending protrusion 114 is engaged with the clasp 143 The first and second frames 110 and 120 are moved in the direction in which they contact both ends of the glass substrate 10 as the latch 143 rotates so as to be separated from both sides of the glass substrate 10 when the first frame 110 is mounted, Side ends of the glass substrate 10 instead of the glass substrate 130. That is, before mounting the first frame 110, the pair of fourth supports 160 are located farther than the width of the glass substrate 10, and when the first frame 110 is mounted, The distance between the glass substrates 160 closer to the glass substrate 10 becomes closer to each other.

A plurality of mounting grooves 161 are formed along the longitudinal direction of the fourth support frame 160. The position, number and shape of the mounting grooves 161 are different from those of the other mounting grooves 121, 131, Respectively.

The reason why the fourth support platform 160 supports both sides of the glass substrate 10 instead of the second support platform 130 is that the third support platform 150 is mounted on the glass substrate 10 Quot;). That is, the fourth support member 160 may be made of any one of a fluororesin such as PTFE, PFA, ETFE, PVDF, PVF, and PEEK for the stability in the cleaning process, have.

Hereinafter, the operation of the glass cassette according to one embodiment of the present invention will be described with reference to FIG. 4 to FIG. Reference will now be made to the drawings in which like reference numerals refer to like elements throughout.

In order to perform a cleaning process on the glass substrate 10, a plurality of glass substrates 10 are mounted on a first support 120 and a second support 130 provided on the first frame 110. At this time, the lower end of the glass substrate 10 is supported by being fitted into the mounting groove 121 of the first supporting base 120, and both side ends of the glass substrate 10 are fixed to the mounting groove 131 of the both side second supporting base 130 Respectively.

When the first frame 110 is mounted on the second frame 120 in such a manner that the first frame 110 on which the plurality of glass substrates 10 are mounted is pressed downward, The glass substrate 10 having the lower end supported by the first support 120 is transferred to the third frame 150 and the lower end thereof is supported by the position difference. At the same time, when the projection 114 of the first wall 111 is caught by the catch 143 of the second wall 141 in the process of moving the first frame 110 in the downward direction, And the fourth support 160 connected to the latch 143 is moved to the side of the glass substrate 10 and is brought into contact with the side edge of the glass substrate 10. In this case, the second support base 130 supporting the side edge of the glass substrate 10 is separated from the side edge of the glass substrate 10 due to a structural factor between the slit 113 and the sliding aperture 146, 4 support frame 160 supports the side end of the glass substrate 10 instead of the second support platform 130.

That is, in one embodiment of the present invention, a plurality of, that is, several tens to several hundreds of glass substrates 10 are automatically and separately provided through a single process of simply mounting the first frame 110 to the second frame 140 It can be transferred to process-specific support.

When the first frame 110 is attached to the second frame 140, the glass substrate 10 is supported by the third support 150 and the fourth support 160 made of a material suitable for the cleaning process , A stable cleaning process can be performed.

Next, a first support 120 and a second support 130 suitable for a high-temperature process, instead of the third support 150 and the fourth support 160, which are susceptible to high temperatures, support the glass substrate 10 The first frame 110 is separated from the second frame 140. In this case, as the height of the first support 120 is higher than that of the third support 150 in the process of lifting the first frame 110, the glass substrate 10 supported by the third support 150, Is again transferred to and supported by the first support base (120). In addition, when the first frame 110 is lifted, the protrusion 114, which has pressed the latch 143, is separated from the latch 143 and is removed by the pressure applied to the latch 143. The latch 143 is rotated in the reverse direction by the elastic restoring force of the elastic member 144 and returns to the original position so that the fourth support 160 connected to the latch 143 is also returned to the glass substrate 10, And are separated from both ends of the glass substrate 10. When the first frame 110 is lifted, the second support 130 moves to the lowest region of the slit 113 by gravity and contacts and supports both ends of the glass substrate 10.

In this way, through a single process of separating the first frame 110 from the second frame 140, tens or hundreds of glass substrates 10 can be transferred to the first support 120 and second After transferring to the support base 130, only the first frame 110 is put into the ion-strengthening process, so that a stable ion-strengthening process can be performed.

In this case, similarly, after one step of mounting the first frame 110 to the second frame 140, the cleaning process may be repeated several tens of times Hundreds of glass substrates 10 can be transferred to the third support 150 and the fourth support 160 suitable for ultrasonic cleaning in a stationary state.

Hereinafter, a glass cassette according to another embodiment of the present invention will be described with reference to FIGS. 8 to 14. FIG.

8 to 14, a glass cassette 200 according to another embodiment of the present invention includes a first frame 210, a first support 220, a second support 230, a second frame 230, 240, a third support 250, and a fourth support 260.

The first frame 210 may include a pair of first walls 211 and a first connecting rod 212. The first wall 210 may include a first wall 111 1 connecting rod 112, and has the same function. Also, the slits 213 formed in the first wall 211 are formed and have the same structure as the slits (113 in FIG. 2) according to the embodiment of the present invention.

In this case, the first frame 210 according to another embodiment of the present invention includes a detachable groove 215. The attaching / detaching groove 215 is formed below the slit 213 in parallel with the direction in which it is tilted. The detachable groove 215 serves to detachably mount the fourth support table 260. Here, the fourth support member 260 having the mounting groove 261 along the longitudinal direction is made of the same material as the fourth support member 160 (see FIG. 1) according to an embodiment of the present invention, and plays the same role .

That is, according to another embodiment of the present invention, as the fourth support frame 260 is mounted on the first frame 210, in order to operate the fourth support frame 160 of FIG. 1 in one embodiment of the present invention, 1) and the elastic member (144 in Fig. 1 are omitted, so that the projection (the projection 114 in Fig. 1) formed in the first frame (110 in Fig. 1) ) Are also omitted.

However, the second frame 240 according to another embodiment of the present invention includes a pair of second walls 241 opposed to each other like the second frame 140 of FIG. 1 according to an embodiment of the present invention And is connected by the second connecting rod 242. The second frame 240 may include a second support 230 when the first frame 210 is mounted on the second frame 240 in the same manner as the second frame 140 of FIG. A guide hole 245 and a sliding hole 246 are formed for separating the glass substrate 10 from both ends of the glass substrate 10 and a pedestal 247 for supporting the first frame 210 to be mounted is formed.

The first support 220, the second support 230 and the third support 250, along which the support grooves 221, 231, and 251 are formed, 1), the second support (130 in FIG. 1), and the third support (150 in FIG. 1), and is formed of the same material and has the same role.

Hereinafter, the operation of the glass cassette according to another embodiment of the present invention will be described.

A plurality of glass substrates 10 are first mounted on a first support platform 220 and a second support platform 230 provided on the first frame 210 in order to perform a cleaning process on the glass substrate 10. The lower end of the glass substrate 10 is supported by the first support 220 and the lower end of the glass substrate 10 is supported by the first support frame 220. [ The upper side is supported by the second support table 230 and the lower side is supported by the fourth support table 260. [ At this time, since the attaching / detaching groove 215 has the same inclination as that of the slit 213 on which the second supporting bar 230 is mounted, when the fourth supporting barrel 260 is mounted on the attaching / detaching groove 215, 4 support frame 260 is located at the lowest area of the attaching / detaching groove 215, and this area is an area in contact with the side end of the glass substrate 10. [ That is, when the fourth support table 260 is attached to the detachable groove 215, the glass substrate 10 is continuously contacted with and supported by the glass substrate 10.

When the first frame 210 is mounted on the second frame 240 in such a manner that the first frame 210 on which the plurality of glass substrates 10 are mounted, for example, The glass substrate 10 supported by the first support frame 220 is transferred to the third frame 250 and the lower end of the glass frame is supported by the third frame 250, It accomplishes. At the same time, the second support table 230 supporting the side edge of the glass substrate 10 is separated from the side edge of the glass substrate 10 due to a structural factor between the slit 213 and the sliding port 246, Only the fourth support member 160, which is not subjected to any pressure when the first frame 210 is mounted on the second frame 240, continuously supports the side edge of the glass substrate 10.

As described above, another embodiment of the present invention is also applicable to a case where a plurality of glass substrates 10 (e.g., a plurality of glass substrates) 10 are formed through a single process of simply mounting the first frame 210 on the second frame 240 ) Can be automatically transferred to another support.

The first frame 210 is lifted from the second frame 240 so that the height of the first frame 220 is lower than the height of the third frame 210 250, the glass substrate 10 supported by the third support 250 is transferred to and supported by the first support 220 again. At this time, when the first frame 210 is lifted, the second support table 230 moves to the lowest area of the slit 213 formed in an inclined shape by the gravity, Contact and support thereof.

When the first frame 210 is completely separated from the second frame 240 and then the fourth support 260 mounted on the detachable groove 215 is removed, tens or hundreds of glass substrates 10 are ion- And is supported by a first support 220 and a second support 230 suitable for the process.

While the invention has been shown and described with reference to certain preferred embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. This is possible.

Therefore, the scope of the present invention should not be limited by the described embodiments, but should be determined by the scope of the appended claims as well as the appended claims.
