According to an aspect of the present invention, there is provided an apparatus for transferring a panel, which rotates and transfers a panel having a predetermined size, the apparatus for transferring a panel comprising: a panel support part which supports the panel and rotates the panel; and a panel conveying unit including a plurality of conveying units, wherein the panel is moved in a predetermined direction by the conveying units, and is lowered or raised below the panel supporting unit so that the panel supporting unit can rotate the panel.

Description

Apparatus for transferring panel

Technical Field

The present invention relates to a panel conveying apparatus capable of conveying a panel after rotating the panel while conveying the panel.

Background

The statements in this section merely provide background information related to the present disclosure and may not constitute prior art.

Fig. 1 is a diagram illustrating a conventional apparatus for rotating and transferring a panel.

in manufacturing and mass-producing panels (panels), the size of the panels is made much larger than that of panels inserted into a general display device. As an example, the panels produced initially have a size of approximately 4m x 4.2 m. The panel having a relatively large size is manufactured to be inserted into a general display device through a number of processes.

since the panels are manufactured through a number of processes, the panels are transported over a considerable distance and a considerable amount of equipment. In this case, as illustrated in fig. 1, if the panel 110 having a longer horizontal axis (x-axis direction) flows into the manufacturing process in parallel with the horizontal axis (x-axis) and passes through all the manufacturing processes, a considerably long transfer distance is passed. Therefore, various inconveniences are caused such that the area of the place where the panel is manufactured must be increased and the manufacturing time of the panel is also lengthened. In order to eliminate such inconvenience, the panel 110 is rotated by 90 degrees in the panel manufacturing process so that the horizontal axis (x-axis) of the panel is perpendicular to the direction in which the panel flows (x-axis).

As a technique of rotating the panel, a panel conveying unit 120 such as a roller is rotated by itself, or the panel is sucked by a pipe or the like and then the sucked panel is rotated at an upper end of the panel conveying unit.

The device for rotating the panel conveying part has the problem that the conveying direction of the panel is unstable. For example, as illustrated in fig. 1, when the panel is to be continuously conveyed in the x-axis direction, if the panel conveying unit 120 rotates 90 degrees to rotate the panel 90 degrees, there is a problem that the panel cannot be continuously conveyed in the x-axis direction. Therefore, there is a problem that a panel transport unit having another direction is additionally provided or another changed panel transport unit different from the changed panel transport unit 120 is additionally provided.

In the method of rotating the sucked panel after sucking the panel by using a pipe or the like, since it is necessary to have a pipe or the like for sucking the panel, a space is considerably limited when the panel is rotated by using the pipe. Since the pipes must be rotated together, an additional space corresponding to the rotation space must be secured, and there is a risk of the pipes being tangled with each other while being rotated, and thus there is an inconvenience that an additional work for removing the tangled pipes must be performed every time the direction is changed.

Fig. 2 is a structural view of an apparatus for rotating and transferring a panel according to an embodiment of the present invention, fig. 3 is a plan view of the apparatus for rotating and transferring a panel according to an embodiment of the present invention, and fig. 4 is a sectional view of the apparatus for rotating and transferring a panel according to an embodiment of the present invention.

Referring to fig. 2 to 4, an apparatus 200 for rotating and transferring a panel according to an embodiment of the present invention includes a panel supporting part 210, a panel conveying part 220, a first power supply 230, a second power supply 240, and a control part (not shown).

The panel support portion 210 supports the panel 310 and rotates the panel by 90 degrees. The panel support part 210 is located at the lower end of the conveying unit of the panel conveying part 220 before or after the panel is rotated, so that the panel 310 can move to another process after flowing or rotating through the panel conveying part 220. Thereafter, the panel to be rotated flows in through the second panel conveying unit 325, or the panel is placed on the panel conveying unit 220 by another mechanism (for example, a robot arm or the like, not shown), and the panel conveying unit 220 is lowered for rotation of the panel. The panel supporting portion 210 receives the power provided by the second power providing device 240 to support the panel 310 and rotate the panel 310 by 90 degrees. After the panel supporting part 210 rotates, the panel transfer part 220 ascends again, so that the panel is seated on the panel transfer part 220.

The panel support portion 210 includes a sensor that detects the amount of rotation of the panel support portion 210. The panel support portion 210 detects how much the panel 310 is rotated by the aforementioned sensor and transmits the detection result to a control portion (not shown) so that the control portion (not shown) can detect how much the panel 310 is rotated. The panel support portion 210 provides information on the amount of rotation of the panel to a control portion (not shown), so that the control portion (not shown) can determine whether the operation of the panel support portion 210 is normal. The panel supporting part 210 will be described in detail with reference to fig. 5.

The panel conveying unit 220 includes a plurality of conveying units to convey the panel in a predetermined direction. The panel conveying unit 220 includes a plurality of conveying units to convey the panel 310. Here, the conveying means may be a roller, but is not necessarily limited thereto, and any means may be substituted as long as it can convey the panel without causing any scratch. Each of the conveying units has a certain diameter and is disposed at the panel conveying portion 220 at a certain pitch. As illustrated in fig. 3, each conveying unit may be arranged in a zigzag (Zig-Zag) shape, and may be arranged in a row.

The panel conveying part 220 descends and ascends so that the panel supporting part 210 can rotate the panel 310. As described above, the panel supporting part 210 is located at the lower end of the conveying unit of the panel conveying part 220 before or after rotating the panel. In order for the panel supporting part 210 to avoid interference with the conveying unit in the process of rotating the panel 310, in the case where the panel 310 is located at a normal position for rotation after being flowed or settled, the panel conveying part 220 is lowered. Thereby, the panel support portion 210 can rotate the panel 310 satisfactorily. The panel conveying portion 220 is sufficiently lowered to the extent that the conveying unit does not contact the panel supporting portion 210. After the rotation is completed, the panel conveying unit 220 is raised again, and the panel 310 can be conveyed in a predetermined direction.

The panel conveying unit 220 moves the panel 310 that has flowed in through the second panel conveying unit 320 or a panel that is placed by another mechanism (not shown) in a predetermined direction (for example, the x-axis positive direction in the example disclosed in fig. 3). The panel conveying unit 220 includes an adjusting unit that adjusts the position of the panel before the panel is rotated by the inflow or the panel to be conveyed in a predetermined direction after the rotation is completed, so that the position of the panel can be adjusted to be completely rotated or conveyed.

The panel conveying unit 220 includes sensors at each corner, and detects whether or not the panel 310 passes over the sensors when rotating. When the panel 310 is rotated normally, the panel 310 must pass through all the sensors disposed at the corners of the panel conveying unit 220. If the panel 310 does not pass through one or more sensors of the sensors disposed at the corners of the panel conveying unit 220, it is described that the panel is biased in a specific direction by centrifugal force or the like and rotated. In order to detect such an abnormal situation, the panel conveying unit 220 includes sensors at each corner, and transmits a detection value detected by the sensors to a control unit (not shown). The control unit (not shown) can determine whether or not the panel 310 is rotating normally, by receiving the detection value. With respect to the panel conveying portion 220, a detailed description will be given with reference to fig. 6 and 7.

The first power supply device 230 supplies power for enabling the panel support portion 210 to rotate to the panel support portion 210. The first power supply means 230 can be implemented by any means such as a motor that can supply a rotational force to the panel supporting part 210.

the second power supply device 240 supplies power for the ascending or descending of the panel conveyance part 220 to the panel conveyance part 220. The second power supply device 240 may also include a cylinder (not shown) connected to the panel transfer unit 220, as in the first power supply device 230, and supply hydraulic pressure to the cylinder so that the panel transfer unit 220 can be raised or lowered. Alternatively, the second power supply device 240 may be implemented by any device that can supply power to the panel conveying unit 220, such as a motor.

The control unit (not shown) controls the operation of each component in the apparatus 200 for rotating and transferring the panel. The control unit (not shown) controls the first power supply device 230 to enable the panel support portion 210 to operate, and receives detection values from the sensors (the rotation detection sensor 540 and the position sensor 650) to control whether the panel support portion 210 operates or not. When the panel is rotated by the panel support portion 210, if the panel conveying portion 220 is raised when the panel 310 is not normally rotated or when the panel support portion 210 is not completely rotated, there is a risk that the panel 310, the panel support portion 210, or the panel conveying portion 220 may be seriously damaged. In order to prevent such a problem, a control unit (not shown) receives a detection value from the sensor and determines a rotation state of the panel 310 or the panel support portion 210. The control unit (not shown) controls the operation of the panel support unit 210 according to the determination result. When the rotation state of the panel 310 or the panel support portion 210 is normal, the control portion (not shown) controls the panel support portion 210 to continuously operate. On the contrary, when the rotation state of the panel 310 or the panel support portion 210 is not normal, the control portion (not shown) stops the panel support portion 210 to prevent further operation in the current state. Since the panel support portion 210 is stopped, the control portion (not shown) can prevent the panel 310, the panel support portion 210, or the panel conveying portion 220 from being damaged.

Fig. 5 is a plan view and a sectional view of a panel supporting part and a power supplying part according to an embodiment of the present invention.

Referring to fig. 5, the panel supporting part 210 according to one embodiment of the present invention includes a main supporting frame (frame)510, an auxiliary supporting frame (frame)520, an auxiliary fixing part 525, a mat 530, a rotation detecting sensor 540, and a guide roller 550.

The main support frame 510 keeps the panel 310 stable and allows the panel 310 to rotate satisfactorily. The main support frame 510 smoothly supports the panel 310 including the center of gravity of the panel 310. The main support frame 510 smoothly supports the panel 310 so that the panel 310 is not biased or deflected even if the panel 310 is rotated. In addition, the main support frame 510 is embodied in a form having the same shape even if rotated 90 degrees. For example, the main support frame 510 is specifically realized in a cross shape, a swastika shape, or the like so as to maintain the same shape as that before the rotation even if rotated by 90 degrees. The main support frame 510 is located at the lower portion of the conveying unit of the panel conveying part 220 before rotating the panel or after rotating the panel, and thus the shape must be the same before and after rotating 90 degrees.

The main support frame 510 is connected to the first power supply unit 230 to receive power for rotating the panel 310. The main support frame 510 is disposed in the empty space of the panel conveying part 220 because it is connected to the first power supply device 230. The first power supply means 230 is embodied as a motor to be able to supply power for the rotation of the main support frame 510.

The auxiliary support frame 520 is disposed at a peripheral portion of the main support frame 510 to assist the movement of the panel. The auxiliary support frame 520 is located at a lower portion of the conveying unit of the panel conveying part 220 and thus located at a lower portion of the conveying unit of the panel conveying part 220 before being ascended without interfering with the conveying of the panel by the panel conveying part 220. Thereafter, the auxiliary support frame 520 is rotated together with the main support frame 510 to assist the rotation of the panel 310.

The auxiliary support frame 520 is located at the lower portion of the conveying unit of the panel conveying unit 220, but is located at the upper portion of the panel conveying unit 220. The conveying units of the panel conveying part 220 are disposed with a certain interval therebetween, and the auxiliary support frame 520 is positioned at a gap between the conveying units. Therefore, the auxiliary support frame 520 does not need to have an empty space inside the panel conveyance part 220 like the main support frame 510. However, since the panel conveying unit 220 ascends after the panel is lowered and then rotates, the auxiliary support frame 520 after the rotation must be disposed again in the gap between the conveying units. Therefore, the auxiliary support frame 520 is also implemented in the same manner as the main support frame 510, particularly in the same manner as the shape before and after the rotation by 90 degrees. For example, the auxiliary support frame 520 may be embodied in a form in which a square lattice is repeated, or may be embodied in a form in which the shape is the same before and after the rotation by 90 degrees, even if the form is not a lattice. When the auxiliary support frame 520 is specifically realized in a form in which lattices are repeated, even if the lattices have other forms of shapes that are not necessarily square, the auxiliary support frame 520 can be specifically realized as long as the shapes before and after being rotated by 90 degrees are the same as illustrated in fig. 5 (specifically, a rectangular lattice is realized together with a square lattice as an example in fig. 5).

Each support frame 510, 520 supports the relatively large and heavy panel 310 and is raised, rotated and lowered, and thus can be implemented using a light and hard material such as CFRP (Carbon Fiber Reinforced Plastic).

The auxiliary support frame 520, which is disposed at the outermost portion of the auxiliary support frame 520 and is close to the rotation axis, further includes an auxiliary fixing portion 525 at the outer periphery. The auxiliary stationary part 520 is illustrated in more detail in fig. 12.

the auxiliary fixing portion 525 is specifically opened at one side "The letter-shape is implemented to place and fix the auxiliary support frame 520 inside. As described above, the auxiliary support frame 520 can be implemented by using a plastic material such as RP (reinforced plastic), which is a light and hard material, to support and move the large and heavy panel 310. The outermost portion near the rotation axis or having a large amount of rotation generates a large amount of heat compared to other portions, and thus the auxiliary support frame 520 of this portion is in danger of being deformed by heat. Thus, when the auxiliary support frame 520 is deformed, the panel 310 may be moved unstably. The auxiliary fixing part 525 receives and fixes the part of the auxiliary support frame 520 inside thereof, so that it is possible to minimize deformation of the auxiliary support frame 520 due to heat. The auxiliary fixing portion 525 fixes the auxiliary support frame 520 placed inside by means of a member (not shown) such as a screw, so that the auxiliary support frame 520 is prevented from moving within the auxiliary fixing portion 525.

Referring again to fig. 5, the cushion 530 is disposed on the main support frame 510 or the auxiliary support frame 520 to minimize the impact of the panel 310 with the main support frame 510 or with the auxiliary support frame 520. In addition, the mat 530 has a friction force above a certain friction force, so that it is possible to minimize the movement of the panel 310 during the movement, particularly, the rotation.

The mat 530 can be embodied in PEEK (Poly Ether Ketone) material, and thus can have a high surface resistance. The mat 530 can minimize the risk of damage or injury to the panel 310 or the panel support 210 due to static electricity generated by minute friction.

The rotation detection sensor 540 is disposed in the panel support portion 210 to detect the amount of rotation of the panel support portion 210. The panel supporting portion 210 must be rotated only 90 degrees accurately, and if the panel supporting portion is lowered in a state of being rotated more than 90 degrees or rotated less than 90 degrees, the supporting frames 510 and 520 or the panel conveying portion 220 in the panel supporting portion 210 may be seriously damaged. In order to prevent such a problem, the rotation detection sensor 540 detects the amount of rotation of the panel support portion 210 and transmits the amount of rotation to a control portion (not shown) so that the control portion (not shown) can appropriately control the amount of rotation of the panel support portion 210. In particular, the rotation detection sensor 540 can be disposed at a position closest to the center of gravity of the panel in the panel support portion 210.

At each end of the panel support part 210, one or more guide rollers 550 are disposed, and the guide rollers 550 prevent the panel 310 from being separated from the outer periphery by centrifugal force while rotating. The guide roller 550 is illustrated in more detail in fig. 11.

The panel 310 may be separated from the periphery by centrifugal force while rotating, and the guide rollers 550 are positioned at each end of the panel support part 210 to contact the panel 310 separated from the periphery, thereby minimizing the movement of the panel 310.

The guide roller 550 is implemented as a rotatable member, and thus can assist in adjusting the position of the panel 310 when the position of the panel 310 is adjusted on the panel conveying unit 220. In addition, when the panel 310 is separated from the outer periphery by centrifugal force while rotating and comes into contact with the guide roller 550, the guide roller 550 is embodied as a rotatable member, and thus the panel 310 can be prevented from being damaged.

Referring again to fig. 5, the first power supply device 230 according to an embodiment of the present invention includes a rotating member 560.

The rotating member 560 is coupled to the panel supporting part 210 to rotate the panel supporting part 210. The rotating member 560 may be implemented by a motor, and rotates the panel supporting portion 210 when the panel conveying portion 220 is lowered to the lowermost position.

Fig. 6 is a plan view of a panel feeding portion according to an embodiment of the present invention, and fig. 7 is a sectional view of the panel feeding portion according to an embodiment of the present invention.

Referring to fig. 6 and 7, the panel conveyance part 220 according to one embodiment of the present invention includes an empty space 615, a conveyance unit 620, a first adjustment part 630, a second adjustment part 640, and a position sensor 650.

as described above, the panel transferring part 220 has to have a vacant space 615 for arranging the main support frame 510 and connecting the main support frame 510 with the first power supply device 230. The empty space 615 is not provided with the conveying unit 620, and is not provided with a shaft (draft) which connects the conveying units 620 and supplies power to the connected conveying units 620. The empty space 615 has the same shape as that of the main support frame 510. In the case where the main support frame 510 has a cross shape as in the example illustrated in fig. 6, the empty space 615 also has a cross shape similar to the cross shape. The panel conveying unit 220 is divided into regions in which the conveying units 620 and the shafts are arranged according to the shape of the space 615. As in the above-described example, when the empty space 615 has a cross shape, the panel conveying unit 220 is divided into a plurality of regions (part), i.e., 610a to 610 d. The number and position of the regions of the panel transfer part 220 may be changed according to the shape of the empty space 615.

the conveying unit 620 has a certain radius, and conveys the panel 310 disposed on the panel conveying unit 220 in a predetermined direction. The conveying unit 620 has a certain radius and protrudes upward (in the positive z-axis direction) from the frame 660 of the panel conveying unit. Therefore, the conveying unit 620 can convey the panel 310 through the conveying unit 620 without contacting the frame 660 of the panel conveying portion. The conveying unit 620 may be implemented by a roller, but is not necessarily limited thereto, and any means may be used instead as long as it can convey the panel 310 without any scratch.

The conveying unit 620 has a certain pitch and is disposed at the panel conveying portion 220. Each of the conveying units 620 is disposed with a certain interval to be able to dispose the auxiliary support frame 520. Each of the conveying units 620 may be arranged in various forms such as a zigzag (Zig-Zag) form and a row form.

The first adjustment part 630 is disposed at a position relatively distant from the center of the panel 310 compared to the second adjustment part 640 to adjust the position of the panel 310. If the center of gravity of the panel 310 is not located at the center of the panel support part 210 before the panel 310 is rotated, the panel 310 is deviated to the outer circumference when rotated. On the other hand, if the center of gravity of the panel 310 is not located at the center of the panel support portion 210 after the panel 310 is rotated, the panel 310 is conveyed while being deviated in one direction when being conveyed by the second panel conveying portion 325. In order to prevent such a problem, the first adjustment part 630 is disposed at a position relatively distant from the center of the panel 310 compared to the second adjustment part 640 to adjust the position of the panel 310. When the panel 310 is assumed to be rectangular, the first adjustment part 630 adjusts the position of the panel 310 before rotation when the longitudinal direction of the panel 310, which is flowed or placed for rotation, is directed to the y-axis. In contrast, in the case where the length direction of the panel 310 placed after the rotation is directed to the y-axis, the first adjusting part 630 adjusts the position of the panel 310 after the rotation. The first regulating portion 630 includes another member, and pushes the panel 310 simultaneously from both sides (from the y-axis positive direction and the y-axis negative direction with the center of the panel as a reference) with the member so that the positions of the panel 310 are arranged in order.

The second adjustment part 640 is disposed at a position relatively closer to the center of the panel 310 than the first adjustment part 630, and adjusts the position of the panel 310. The reason why two adjustment portions (a first adjustment portion and a second adjustment portion) are used is the shape of the panel 310. Since the panel 310 has a rectangular shape, the case where the panel 310 is apart from the first regulation part 630 before or after the rotation must occur once. Therefore, if only one adjustment portion is provided, there is a problem that it is impossible or difficult to satisfactorily adjust the position of the panel 310 before or after the rotation. Therefore, the second adjustment portion 640 is disposed at a position closer to the first adjustment portion 630 to adjust the position of the panel 310. The second regulating part 640 regulates the position of the panel 310 complementarily to the first regulating part 630. When the first adjusting part 630 adjusts the position of the panel 310 before rotation, the second adjusting part 640 adjusts the position of the panel 310 after rotation, and when the opposite is true, the second adjusting part 640 adjusts the position of the panel 310 before rotation. When the length direction of the panel 310 flowed or placed for rotation is directed to the y-axis, the second adjusting part 640 adjusts the position of the panel 310 after being rotated. In contrast, when the length direction of the panel 310 placed after being rotated is directed to the y-axis, the second adjusting part 640 adjusts the position of the panel 310 before being rotated. The second regulating part 640 also pushes the panel 310 from both sides of the panel 310 to regulate the position of the panel 310, like the first regulating part 630.

on the other hand, since the second adjustment part 640 is disposed at a position relatively close to the first adjustment part 630, the following problem occurs. When the long axis of the panel 310 is disposed at a position relatively close to the first adjustment part 630, the position of part or all of the second adjustment part 640 may collide with the position of the panel 310. In order to prevent such a problem, the second adjustment unit 640 is arranged at a lower portion of the panel 310 (negative z-axis direction) when the panel 310 is positioned in a direction that conflicts with the position of the second adjustment unit 640, and then is raised (positive z-axis direction) to adjust the position of the panel 310 when the panel 310 is arranged in a direction that does not conflict with the position of the second adjustment unit 640, according to the control of the control unit (not shown).

The position sensor 650 is disposed at each corner of the panel conveying unit 220 to detect whether or not the panel 310 is positioned on the position sensor 650. Since the position sensor 650 is disposed at each corner of the panel conveying unit 220, it is positioned above the position sensor 650 only when the panel is rotated (temporarily). When the panel 310 is rotated, if the panel is located above all the position sensors 650, it is considered that the panel 310 is rotated satisfactorily without being deviated from the normal position (the center of the panel support portion). However, if the panel 310 is not located on one or more position sensors at the time of rotation, the panel 310 may be deviated to one side from the normal position. In this case, if the panel support portion 210 is further rotated, the panel 310 may be damaged. The position sensor 650 is disposed at each corner of the panel conveying unit 220 to detect whether the panel 310 is positioned thereon, and then provides a detection result to a control unit (not shown) so that the control unit (not shown) can detect whether the panel 310 is normally rotated.

Fig. 8 is a perspective view of a panel feeding portion according to an embodiment of the present invention, as viewed from below, and fig. 9 is a plan view and a sectional view of a second power supply device according to an embodiment of the present invention.

The second power supply device 240 is connected to a lower end of the panel conveying part 220 (opposite to the direction of the panel supporting part) and supplies power to raise or lower the panel conveying part 220.

The second power supply device 240 includes a power unit 910, a lifting unit 920, and a frame (frame) 930.

The power member 910 provides power for raising or lowering the panel feeding portion 220. The power member 910 is directly connected to the panel conveying unit 220 and can raise or lower the panel conveying unit 220. However, when the power member 910 is directly connected to the panel feeding unit 220, it is only partially connected to the panel feeding unit 220, and therefore, there is a problem in that it is difficult to uniformly raise or lower the panel feeding unit 220 without being biased in one direction. Therefore, the power member 910 is connected to the frame 930 to raise and lower the frame 930, thereby raising and lowering the panel conveying unit 220.

As shown in fig. 9, the power unit 910 may be implemented as a unit that raises or lowers the elevation unit 920. The power member 910 may be implemented as a member that converts a rotational motion into a Linear motion, like a Linear Motor (LM), or may be implemented as a member that directly raises or lowers the elevation member 920 using a hydraulic cylinder.

The frame 930 is provided with the panel conveying unit 220 at the upper end, and ascends or descends by the power of the power unit 910. The frame 930 contacts the panel transfer unit 220 over a wide area, so that the panel transfer unit 220 is uniformly raised or lowered without deviating in one direction in the process of raising or lowering the panel.

Fig. 10 is a cross-sectional view of a second panel transport according to one embodiment of the invention.

The second panel transfer parts 320 and 325 make the panel 310 to be rotated flow into the apparatus 200 that rotates and transfers the panel or transfer the rotated panel 310 to other apparatuses. At this time, assuming that the direction in which the panel 310 flows into the apparatus 200 that rotates and transfers the panel is the positive x-axis direction, the second panel conveying section 320 configured to flow the panel into the apparatus 200 that rotates and transfers the panel and the second panel conveying section 325 configured to convey the panel from the apparatus 200 that rotates and transfers the panel to another apparatus have different widths. Since the rotation of the panel occurs in the apparatus 200 for rotating and transferring the panel, one side has to have a width of a degree that a long axis of the panel 310 can be arranged, but the other side has to have a width of a degree that a short axis of the panel 310 can be arranged. Accordingly, the second panel transfer parts 320 and 325 may have different widths from each other.

Fig. 13 is a diagram illustrating a process of arranging panels at a panel conveying part according to an embodiment of the present invention. In the following description of fig. 13, an example in which the long axis of the panel 310 flows in the y-axis direction and then rotates in the x-axis direction is described, but the apparatus 200 for rotating and transferring a panel is not limited to this example and operates.

The panel 310 to be rotated flows in through the second panel conveying portion 325, or the panel 310 is mounted on the panel conveying portion 220 by another mechanism (for example, a robot arm, not shown).

The first adjusting part 630 disposed in the panel conveying part 220 pushes the panel 310 from both sides of the panel 310 to adjust the position of the panel 310. At this time, the second adjustment part 640 is located at the lower end (z-axis negative direction) of the panel 310 because its position collides with the panel 310. The first adjusting part 630 adjusts the position of the panel to enable the panel 310 to be normally rotated at the normal position.

The panel conveying unit 220 receives power from the second power supply device 240 and moves down (in the negative z-axis direction). The panel conveying portion 220 is sufficiently lowered to the extent that the conveying unit does not contact the panel supporting portion 210.

Fig. 16 is a diagram illustrating a process in which a panel supporting part rotates a panel according to an embodiment of the present invention.

After the panel conveying portion 220 descends, the panel supporting portion 210 rotates the panel 310 by 90 degrees. Since the panel support portion 210 does not use a separate tube or the like, it may be rotated in any direction (clockwise or counterclockwise).

Fig. 17 is a diagram illustrating a process in which a panel conveying part ascends according to an embodiment of the present invention.

After the panel 310 rotates, the panel conveying portion 220 ascends again. Since the panel supporting part 210 has the same shape before and after rotating by 90 degrees, any problem does not occur even if the panel feeding part 220 ascends after the panel supporting part 210 rotates.

In the case where the panel supporting part 210 is lowered and the panel 310 is seated on the panel transferring part 220, the second adjusting part 640 is raised to adjust the position of the panel 310 so that the panel 310 can be transferred to the second panel transferring part 325 at a normal position. The second regulating portion 640 also regulates the position of the panel 310 by pushing the panel 310 from both sides of the panel 310, like the first regulating portion 630.

The above description is merely exemplary in nature and is intended to illustrate the technical idea of the present invention, and many modifications and variations can be made by those skilled in the art without departing from the essential characteristics of the present invention. Therefore, the above-described embodiments are intended to illustrate the technical idea of the present invention and not to limit the technical idea of the present invention, and the scope of the technical idea of the present invention is not limited by the embodiments.
