TECHNICAL FIELD OF THE INVENTION
The present invention relates to a thin panel erecting device for erecting a thin panel such as a liquid crystal glass substrate in an inclined state at a predetermined angle while being placed on a plane.
[0002]
[Prior art]
Liquid crystal glass substrates applied to display devices of personal computers and the like tend to become larger year by year. Things are getting bigger.
Such a liquid crystal glass substrate is transported horizontally on a conveyor surface or the like one by one or in a horizontally transported state in which a plurality of the substrates are stacked.
When transporting a relatively small liquid crystal glass substrate, about 20 liquid crystal glass substrates were inserted into a cassette, and the cassette was transported by an automatic transport device. In the processing step, the cassette was equipped at the tip of a rod arm. They are taken out with a vacuum suction pad, and after processing, they are delivered to the cassette again.
However, when the liquid crystal glass substrate is handled with a vacuum suction pad, the center of the thin liquid crystal glass substrate bends (approximately 80 mm in a medium-term liquid crystal glass substrate), and is broken or deformed. It is an obstacle to production.
Since the size of the liquid crystal glass substrate is increasing, it is almost impossible to move the liquid crystal glass substrate by sucking it with a vacuum suction pad of a rod hand.
Furthermore, in the production of medium-sized and small-sized liquid crystal glass substrates, there is a demand for performing a cleaning process and a baking process on the liquid crystal glass substrate while the substrate is tilted.
[0003]
In connection with such a method of transporting a thin panel and a handling device, for example, the following technology is known.
(1) In Patent Document 1, a porous body having a flat portion is attached to an upper part of a main body into which a pressure liquid is sent, so that the pressure liquid is ejected through the porous body, and a plate-like member to be conveyed. A conveying device for a plate-like member is described in which rollers for driving both sides are provided to wash the plate-like member while conveying the plate-like member.
(2) Patent Document 2 discloses that a pressure fluid is ejected through a porous body having a plane portion, and that the plane portion of the porous body is inclined or vertical so that the pressure ejected from the porous body is increased. A plate-like member transfer device provided with a transfer unit that supports and transfers a lower end portion of a plate-like member supported by a fluid is described.

[Problems to be solved by the invention]
However, the conventional technology has the following problems.
(1) In the apparatus using the plate-like member conveying device described in Patent Document 1, there is no effective means for erecting the horizontally conveyed plate-like member at a predetermined inclination angle at the end thereof. Therefore, there has been a problem that it is not possible to efficiently process a large amount of liquid crystal glass substrates.
(2) In the transfer device described in Patent Literature 2, since the plate member is arranged with a fixed inclination angle, the plate member placed horizontally on a panel surface or the like is mechanically moved by a vacuum suction pad or the like of a robot arm. Therefore, there is a problem that the reliability of quality is lacking because the contact portion with the plate-shaped member is easily damaged or deformed.
(3) When the plate-like member is horizontally conveyed by the roller conveyor, if the plate-like member is thin, warpage occurs, so that when the plate-like member moves from one roller to the next roller, this end portion collides with the roller and is broken. It becomes a factor. Therefore, there is a limit to the speed at which the sheet can be conveyed without damaging the plate-shaped member, and it is difficult to improve the productivity to a certain level or more.
(4) The definition of a liquid crystal display device is increasing year by year, and the liquid crystal glass substrate must be thinned in order to increase the definition. However, there has been a problem that as the liquid crystal glass substrate is made thinner, it becomes weaker against impact and productivity cannot be improved.
(5) In order to clean the front and back surfaces of the plate-like member placed on the panel surface or the like, the plate-like member needs to be inverted. However, recent liquid crystal glass substrates for liquid crystal display devices have a large thickness. Of 0.7 mm, 800 mm in height, and 1100 mm in width are often used. Thus, when the thin and wide liquid crystal glass substrate is gripped and lifted at both ends, the bending at the center becomes about 80 mm. Therefore, the operation of inverting a thin liquid crystal glass substrate is not easy, and there is a problem that a complicated apparatus is required for the inversion.
[0007]
The present invention has been made in order to solve the above-described problems, and can efficiently process a large amount of thin panels, reduce the load applied to the normal direction of the thin panel surface, and convey the thin panels. In addition to improving the quality and yield of the thin panels, handling operations such as taking out and inverting the thin panels transported by a conveyor device without mechanical contact using a robot arm etc. are easy and quick. It is an object of the present invention to provide a thin panel erecting device which can be performed in a short time.
[0008]

Since the inclined conveying roller is provided to contact the lower end of the thin panel when the panel mounting part is inclined, the thin panel on the panel mounting surface is arranged adjacent to the thin panel erecting device. The panel can be efficiently supplied to an inclined conveying device or a processing device that conveys the panel in an inclined state.
The thin panel can be floated on the panel mounting surface and held by the airflow or liquid flow ejected from the porous body, so that the thin panel does not contact the panel mounting surface and is generated by contact with the transport roller. Roller marks and scratches are reduced, and the quality of the transported thin panel is excellent.

The rotating shaft of the provided panel rotating unit is provided, and the panel mounting unit of the standing device is rotated by the power of the torque motor. In this way, the operation of raising the liquid crystal glass substrate floated on the panel mounting surface from the horizontal position to an inclination angle of about 75 to 85 degrees is smoothed, and the shock at the time of starting and stopping the panel rotating unit is reduced. Thus, the thin panel can be supplied to the next step without damaging the thin panel.
[0010]
(3) The erecting device for a thin panel according to the present invention, wherein an end of a horizontal transfer device that mounts and transfers the thin panels in a stacked manner is connected to the panel mounting portion, and is located on an end side perpendicular to the end.

With this configuration, when a thin panel conveyed in a processing step such as a liquid crystal glass substrate is transferred from the horizontal transfer device to the inclined transfer device, or when the thin transfer panel is transferred from the inclined transfer device to the horizontal transfer device, the line to the different line is changed. The moving operation can be performed efficiently and quickly via the standing device while maintaining the quality reliability.

It is also possible to reduce the cost and the cost of the apparatus by properly arranging the porous body.
[0015]
The panel rotating unit 13 includes a torque motor 17, a rotating shaft 14 driven by the torque motor 17, a support member connected to the rotating shaft 14, and the like. 11 can be rotated from a horizontal position to a predetermined inclination angle.
[0016]
The inclined conveyance roller 19 is driven to rotate by a motor 19a disposed on the panel mounting portion 11 via a chain, a drive belt 18b, or the like, and thereby is mounted on the panel mounting portion 11 and stands upright. In this state, the liquid crystal glass substrate A is supplied to, for example, the inclined conveyance device 30 of the next process which is arranged adjacently.
[0017]
The thin panel erecting device 10 is provided with a position sensor for detecting the mounting position of the liquid crystal glass substrate A and a control device for detecting the signals of the position sensor and controlling the operations of the torque motor 17 and the motor 19a. . The position sensor and the control device detect that the liquid crystal glass substrate A has contacted the inclined transfer roller 19 on the panel mounting surface 11a from the horizontal transfer device 21 or the like arranged adjacent to the panel mount unit.

Can be.
[0018]
The balance weight 16 attached to the front side of the extension member 15 is made of a heavy metal such as lead. This cancels out the rotational moment added by the weight of the panel mounting portion 11 whose one end is fixed to the rotating shaft 14, and the rotating operation by the panel rotating portion 13 can be performed with a small force. . Further, even when a sudden load is applied from the outside, the movement due to the rotation moment is increased by increasing the rotational moment due to the total mass of the balance weight 16 and the panel mounting portion 11, so that the conveyed liquid crystal glass substrate A starts rotating. At the time of the return and the operation at the time of return, so as not to be damaged.
[0019]
The operation of the upright apparatus 10 for thin panel according to the present embodiment configured as described above will be described.
First, the liquid crystal glass substrate A, which has been horizontally conveyed and held in a horizontal direction from the previous process, is placed on the horizontal transport roller 20 of the horizontal transport device 21, and the horizontal transport roller 20 is rotated by the driving force of the motor 18a. By doing so, it is transported and supplied to the panel mounting portion 11 of the upright device 10.
When the front end of the liquid crystal glass substrate A is inserted into the panel mounting surface 11a, the horizontal transfer rollers 18 which are in contact with the surfaces on both sides of the liquid crystal glass substrate A and are arranged on the line along the traveling direction are driven by the motor 18a. , The leading end of the liquid crystal glass substrate A comes into contact with the inclined conveying roller 19 and is stopped at that position (final position).
In this way, the tip of the conveyed liquid crystal glass substrate A comes into contact with the inclined conveyance roller 19, receives a signal reaching a specified position (final position) from a sensor (not shown), and outputs a torque provided to the erecting device 10. The motor 17 is started.
[0020]
During this time, the central portion of the liquid crystal glass substrate A is floated while being kept in a non-contact state with the panel mounting surface 11a by a floating unit having a plurality of porous bodies 12 mounted on the thin panel erecting device 10.
That is, a pressure fluid such as air is jetted from the air-permeable pores of the porous body 12 in advance through a levitation unit provided with the fluid supply unit 12b, and a gas film is generated on the surface of the porous body 12 made of ceramics. . This gas film creates a state in which the liquid crystal glass substrate A floats on the porous body 12. This is the same even when the liquid crystal glass substrate A is in a horizontal state. The levitation unit includes a porous body 12, a compressed air introduction pipe (fluid supply pipe) 12a, and a fluid supply section 12b such as a case or a pressure vessel surrounding the four circumferences and the bottom of the porous body 12. Thus, the liquid crystal glass substrate A is maintained in a state of floating from the back side.
[0021]
The horizontal transport rollers 18 and 20 are both driven by a motor 18a via a drive belt 18b. However, an independent drive unit is provided for each so that the transport operation of the liquid crystal glass substrate can be performed individually. It may be. Further, instead of making the horizontal transport device 21 independent of the configuration of the upright device 10, the upright device can be configured by incorporating such a horizontal transport mechanism.
[0022]
Next, with the liquid crystal glass substrate A floating and held on the panel mounting surface 11a, the torque motor 17 rotates the rotation shaft 14 of the panel mounting portion 11 to support the liquid crystal glass substrate A in a non-contact floating state. While the panel mounting portion 11 is standing upright, the rotation is stopped when the tilt angle reaches a predetermined angle (about 80 degrees).
At this time, the panel mounting portion 11 has a balance weight 16 for balancing the weight of the panel mounting portion 11 on the opposite side of the rotating shaft 14 and has a predetermined rotational moment, so that an impact at the time of starting is prevented, In addition, the rotation operation can be performed smoothly, and damage to the liquid crystal glass substrate A can be effectively prevented.
Thus, the liquid crystal glass substrate A held in a floating state inclined to the panel mounting portion 11 is operated with the inclined transport roller 19 abutting on the lower end thereof.
As a result, as shown in the operation explanatory view of FIG. 4, the liquid crystal glass substrate A is transferred to the inclined transfer device 30 arranged adjacent to the erecting device 10 in the inclined state.
The inclined conveying device 30 includes an inclined panel mounting portion 31 held at a predetermined inclination angle, and a fluid such as air is ejected in a planar manner onto a front side of the inclined panel mounting surface 32 of the inclined panel mounting portion 31. A porous body 12 similar to the erecting device 10 formed in the shape of a rectangular flat plate is arranged.
In addition, a roller 33 is provided below the inclined panel mounting portion 31 to contact and support the lower end of the tilted liquid crystal glass substrate A, and the roller 33 is rotated by a motor 34 so that the liquid crystal glass substrate A is rotated. Is transported to the next step in an inclined state so that the liquid crystal glass substrate A can be subjected to a double-sided cleaning process, a processing process, and the like.
[0023]
In a transfer device that transfers a window glass for construction from a horizontal state to a vertical type, the window glass is mounted on a conveyor roller, the conveyor rollers are erected together, and sent to the next process using a horizontal transfer conveyor roller. I have. In this case, the rotation direction of the conveyor roller is different from the rotation direction of the horizontal transport conveyor roller. For this reason, even if the rotation of the conveyor roller is stopped and the horizontal conveyor roller is used, the conveyor roller supporting the window glass becomes a resisting force. Also, leaving a roller mark on the surface of a substrate requiring cleanliness, such as a liquid crystal glass substrate, is an obstacle to production.
However, if the apparatus for raising a thin panel according to the present invention is applied, the liquid crystal glass substrate A can be floated and held, and the contact portion with the transport roller can be reduced, so that the influence of the conveyor roller can be minimized, and failure (damage) can be prevented. , Contamination) can be suppressed and the liquid crystal glass substrate can be inserted into and removed from the vertical processing apparatus.
[0024]
When the size of the liquid crystal glass substrate A increases, the periphery of the liquid crystal glass substrate A is sucked by a vacuum suction pad, and the liquid crystal glass substrate A transported horizontally by a multi-axis mechanism such as a rod arm is inverted by the liquid crystal. This is almost impossible because the bending of the glass substrate A causes damage. However, when a thin panel erecting device (seesaw type inverted base) equipped with a floating unit is used, the liquid crystal glass substrate A can perform an erecting motion in a floating state, so that the liquid crystal glass substrate A is less flexed and may be damaged. There is no.
In this way, the thin panel erecting device 10 can be used without any inconvenience when applied not only to the large-sized liquid crystal glass substrate A but also to the medium-sized or small-sized liquid crystal glass substrate A. Rather, there is an advantage that the liquid crystal glass substrate A is prevented from being damaged or stained, and an expensive robot device is not required.
Since a seesaw-type device having a balance weight is used as the thin panel erecting device, the weight before and after the rotation axis of the panel rotation portion is averaged. Therefore, it is possible to drive the upright device of the thin panel with a small rotating force.
This erecting device can also be used as a device for horizontally tilting the liquid crystal glass substrate A transported from a vertical device (a vertical device for performing washing, baking, etc.).
[0025]
