The present invention relates to an apparatus and a method for taking out and holding a rectangular flat glass plate on a conveyor to be conveyed with the support of only the edge portion, and moving and mounting it on a support that can be supported only by the edge portion.

In addition, the present invention relates to a method and apparatus for inserting a rectangular flat glass plate in a vertical posture by isolating each one of the left and right grooves in a box-shaped container by contacting the glass plate surface without contact with only the edge portion.

The present invention also relates to a position adjustment device for a glass plate storage container, and more particularly, to a precise position adjustment device for a box-type container for storing a rectangular flat glass plate one by one and storing it in a vertical position.

Conventionally, when moving and mounting a flat glass plate from a certain position to a separate position, the method and apparatus for carrying and carrying out the adsorption holding and holding of the substantially center part of a glass plate surface with an adsorption pad by a multi-joint robot or an automatic machine are well carried out. Known.

However, when moving and mounting glass substrates used for display panels, such as a plasma display panel, a liquid crystal monitor panel, etc. by handling, a state which does not adsorb | suck a trace or contamination etc. to a glass plate surface, ie, avoids contact with a glass surface as much as possible. It is better to mount on the go.

For example, Japanese Laid-Open Patent Publication No. 2003-158168 discloses a substrate movement mounting apparatus for adsorbing a substrate such as a semiconductor wafer in a cassette by a vacuum suction pad and moving the substrate in a transport container.

For example, Japanese Unexamined Patent Publication No. 2003-292153 discloses a glass substrate sheet having a stacking portion of a glass substrate for exchanging a glass substrate between at least one of the forklifts of the mobile mounting apparatus on at least one end of the sheet conveyance table for conveying the glass substrate. The conveying apparatus WHEREIN: A glass substrate is made to float by forming many small diameter air ejection openings on the surface of a sheet | seat conveyance board, and the roller which is rotationally driven by a drive mechanism is provided in the both sides of a sheet | seat conveyance board, and glass is between these rollers. The sheet | seat conveyance apparatus of the glass substrate characterized by conveying a glass substrate by clamping a board | substrate is disclosed.

Furthermore, for example, Japanese Patent Laid-Open No. 2003-104545 uses air pressure or ultrasonic waves to hold only the edge portion of a flat panel such as a liquid crystal glass substrate to maintain the non-contact state of bending of the panel middle portion. And a device for supporting the panel so that the panel can be oriented vertically and horizontally. Or the flat panel horizontal movement mounting robot which has the hand which grips only the edge part of flat panels, such as a liquid crystal glass substrate, and supports the curvature of the panel middle part in a non-contact state using air pressure or an ultrasonic wave is disclosed. That is, Japanese Laid-Open Patent Publication No. 2003-104545 has a redirection mechanism for converting the posture of the panel into a vertical posture and a horizontal posture, and the bottom side of the flat panel in the vertical posture with a hook, A flat panel longitudinal movement-mounted robot having a hand that adsorbs a side with a suction pad and floats the middle portion of the panel with air pressure to support it in a non-contact state is described.

Since Japanese Patent Laid-Open No. 2003-158168 discloses that the substrate is adsorbed by the adsorption pad and moved to mount, the trace of the adsorption pad remains on the substrate.

Moreover, since what was described in Unexamined-Japanese-Patent No. 2003-292153 is carried out by lifting up the glass substrate of a horizontal attitude | position by the hook-shaped member of a mobile mounting apparatus, it is good when it carries out mounting from horizontal position to a horizontal position, In the mobile mounting of the posture glass plate, in order to lift the glass plate to the fork hook member, it is necessary to insert the fork hook member from the lower end of the glass plate, and set the glass plate to a position higher than the length of the hook of the fork. And, the handling method of such a glass plate is not a realistic method as the size of the glass plate becomes a large size.

In addition, Japanese Patent Laid-Open Publication No. 2003-104545 has a substrate for holding only the panel, but the holding of the panel only changes the posture of the panel into a vertical posture and a horizontal (horizontal) posture (posture conversion). This is the case of the redirection mechanism. In addition, the clamp or grip only on the edge portion of the panel is a case where the robot is horizontally mounted on the panel. The clamp or grip is not the end portion of the panel but clamps or grips the peripheral portion of the panel. It is considered as a problem.

In addition, the flat panel vertical movement mounted robot described in Japanese Patent Laid-Open No. 2003-104545 supports the bottom side of the flat panel in the vertical position with a hook and adsorbs the upper end side with the adsorption pad. There is a problem that adsorption traces or adsorption contamination occurs.

Moreover, in the storage and transportation of the thin flat glass of the rectangular shape conventionally, the several sheets of glass plate were made to be in a vertical position, the paper lamination and the buffer material for glass plates were sandwiched, and they were loaded on the pallet and the wooden box.

However, some glass substrates used for display panels and the like cannot be packaged without their adsorption traces, traces of conveying rolls, contamination, dust, fingerprints, and the like. Both the left and right longitudinal sides of the glass substrate and the both ends of the lower side were inserted into the grooves provided on the left and right sidewalls and the lower edges of the packing container so as not to fall, and the glass plates were not brought into contact with each other. .

Although the loading work of the glass plate to the groove part of such a box-shaped container was performed by the manual operation by another hand, it is difficult for the other hand to handle large glass size, It is necessary to carry out by automatic machines etc.

In order to automatically insert a glass plate into a box-shaped container with grooves, the glass surface is moved by using an adsorption pad having almost no adsorption traces, or holding the periphery of the glass plate or sandwiching the edge portion of the opposite side of the glass plate to support the glass plate with only the edge portion. There has been a need for a method of mounting.

When only one surface of the glass surface is required to be clean and the surface can be adsorbed on the other surface, the surface can be handled by adsorbing the adsorptive surface with an adsorption pad.

As an apparatus for automatically moving and mounting a glass substrate on an edge, for example, Japanese Patent Application Laid-Open No. 07-153816 discloses that a circular substrate such as a semiconductor or a photo mask of a liquid crystal panel is moved from a first cassette to a second cassette. The present invention relates to a method and an apparatus for interposing a substrate, and that the substrate is automatically moved in a longitudinal direction by sandwiching an end surface of the substrate.

For example, Japanese Unexamined Patent Application Publication No. 09-040111 discloses a glass substrate for a liquid crystal display device in which a pair of joining portions (cutout portions) opposed to each other are formed in a peripheral portion outside a region for forming a liquid crystal display on a glass substrate. It is a mobile mounting method which moves and mounts the said glass substrate to a empty cassette from the silk cassette which accommodated the said, After pushing up the said glass substrate from a silk cassette between the said silica cassette and the loading part of a empty cassette, the said pushed glass A moving mounting method of the glass substrate for a liquid crystal display device which grasps the coupling part of a board | substrate and then accommodates a glass substrate in a blank cassette is disclosed.

Furthermore, for example, Japanese Patent Application Laid-Open No. 2000-351448 discloses a plurality of glass substrates for the plasma display panel housed in the storage case 30 which are adsorbed by the handling robot and inclinedly stacked in a state of being stored in the storage case. A method and apparatus for loading with paper on a bed are disclosed.

JP-A-H07-153816 discloses suspending by clamping the upper ends of opposing longitudinal edges of a glass substrate, since beads for partitioning the glass plate in the cassette are provided up and down. The clamp position is limited to the upper end portion, and when the size of the glass plate is a large size, the risk of falling or the like is large and cannot be coped with, and is limited to the mobile mounting of the small sized glass substrate.

In addition, the Japanese Unexamined Patent Application Publication No. 09-040111 discloses that a cutout portion is provided as an engaging portion S3 on an opposite side of the glass substrate, and the cutout portion is clamped with a hook of a gripping means to suspend the glass substrate. In the case where the size of the glass plate is a large size, there is a high risk that the glass plate may fall from the cutout and fall, and the glass plate is limited to the mobile mounting of the small sized glass substrate.

Moreover, what was described in the said Unexamined-Japanese-Patent No. 2000-351448 is a thing which adsorb | sucks and mounts a glass substrate with an adsorption pad, and there exists a problem in the specification of the customer which concerns about a trace of an adsorption pad on a glass substrate.

Moreover, in order to insert a glass plate automatically into the box-shaped container which has the said groove part, it is necessary to precisely position and load the box-shaped container in a predetermined position.

As a positioning structure and a positioning method of a storage container such as a glass plate, for example, Japanese Patent Laid-Open No. 11-168136 discloses a plurality of positioning pins of an automatic machine and a plurality of positioning means of a precision substrate storage container body. If it is not shifted, the recesses of the positioning means are positioned by positioning the positioning pins, and when the plurality of positioning pins and the plurality of positioning means are displaced, the respective positioning pins are positioned. The positioning method of the precision board | substrate storage container characterized by sliding in contact with the guide surface of the said guide member, and making it position by fitting the recessed part of the said positioning means to each said positioning pin.

For example, Japanese Unexamined Patent Application Publication No. 2005-064279 discloses four corner portions of the bottom of the middle box 4 in a horizontally laid down position with leg portions 4c, and arranges L-shaped projections at four positions of the stage. In addition, it is described that the middle box can be accurately positioned on the stage by engaging the outer edge portion of the leg portion 4c of the middle box with the inner edge portion of the positioning portion of the stage.

For example, Japanese Unexamined Patent Application Publication No. 07-315550 discloses that a pallet transported on a conveyer conveyor stops in contact with the front end of the pallet stopper 9 and moves up and down to support the pallet stopper 9. It is disclosed that the stopper cylinder 14 is fixed, and the pallets are fixed by inserting the positioning pins 16 and 17 into the backup positioning holes provided in the backup plate 15.

Since the positioning structure described in Japanese Patent Laid-Open No. 11-168136 cannot correct the position or angle of the box-shaped container positioned on the stage more precisely, the recess for positioning the bottom of the box-shaped container And the manufacturing precision of the groove part which inserts and supports the board | substrate provided in a container inner wall is calculated | required, and even if there is a manufacturing error of such a container, it cannot cope.

In addition, Japanese Patent Laid-Open No. 11-168136 discloses a compact object for positioning a small container on an automatic stage for storing a substrate made of a semiconductor wafer, mask glass or the like having a diameter of about 300 mm on a large diameter. Therefore, although positioning by fitting between the positioning pin 14 which protruded upwards from the stage 13 and the recessed part of a container lower surface is possible, the length of one side is 2 m or more from 1 m or more. In the case of a large container in which dozens of substrates are loaded, the strength that can withstand the weight at the time of loading the substrate is required, so that the weight of the container itself is also a large amount, which may cause deformation of the positioning pin.

In addition, in the positioning structures described in Japanese Patent Application Laid-Open Nos. 2005-064279 and Japanese Patent Laid-Open No. 07-315550, the legs of the medium-sized box 4 are formed at the inner edges of the positioning portions provided in the four corners of the stage. By joining the outer edges of 4c), the medium box is accurately positioned on the stage, but similarly to Japanese Patent Laid-Open No. 11-168136, even if there is a manufacturing error in the medium box positioned at the same position on the stage, You cannot make corrections.
