Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flat plate-shaped member holding device used when moving a flat plate-shaped member such as a glass plate used in a liquid crystal panel between processes.

[0002]

2. Description of the Related Art As is well known, liquid crystal panels are incorporated in various devices as display panels. With respect to the size of the panel (plate glass), a wide variety of sizes are used, excluding general-purpose products, and it is necessary for manufacturers to produce various small quantities.
In the case of small-quantity production, it is difficult to automate the process like a general-purpose product in terms of cost. Therefore, when moving a flat-plate member for small-volume production between the steps of cleaning, resist coating, etching, etc., an operator manually moves the plate-shaped member by using an appropriate gripping tool such as a clip. .

[0003]

Therefore, there is a problem that the workability is poor and the productivity is lowered, and when the flat plate-like member is fragile like glass, this problem becomes more remarkable. It was Therefore, an object of the present invention is to provide an apparatus capable of holding and moving a plurality of flat plate-like members such as glass plates at one time.

[0004]

In order to achieve the above-mentioned object, a flat plate holding device according to the present invention is constructed as follows. A plurality of holder parts for holding flat plate-shaped members such as glass plates are provided in the frame, an insertion part for inserting the flat plate-shaped member is provided in the holder part, and a groove part is provided in the insertion part. In the groove, a sphere made of a magnetic material for holding the flat plate-shaped member on the shallow side of the groove is provided so as to be movable in the groove. The deepest part of the groove is deep enough to release the holding of the flat member when the sphere is located at the deepest part, and the deep side of the groove fixes the sphere to fix the sphere. A member is provided.
The sphere fixing member is provided with a magnet that magnetically attracts and holds the sphere when the flat member is inserted into the insertion portion to make the sphere movable, and the sphere fixing member is made of an elastic member. The frame is biased upward, and the frame is provided with lock releasing means for pushing down the spherical body fixing member against the biasing force of the elastic member.

[0005]

When the flat plate member is inserted into the insertion portion of the holder, the sphere inside the groove moves upward due to the movement of the flat plate member. Then, when the holder is lifted, the flat plate member is lowered by its own weight, and at the same time, the sphere is also lowered. Since the bottom of the groove portion becomes shallower as it goes downward, the flat plate-like member is sandwiched and fixed between the sphere and the wall of the insertion portion. When the fixation of the flat plate-shaped member is released, the flat plate-shaped member is temporarily raised upward, and under this state, the lock releasing means is pushed and the spherical body fixing member is pushed down. As a result, the sphere is adsorbed and held against the magnet provided on the sphere fixing member against its own weight. For this reason, when the holder is lifted up, there is nothing for fixing the flat plate member, so that the flat plate member can be easily removed from the holder.

[0006]

The details of the present invention will be described below with reference to preferred embodiments. As shown in FIGS. 1 and 2, a plurality of holders 2 are provided on both sides of a rectangular frame 1.
The holder 2 is provided symmetrically in the drawing. Engaging portions 5 used when the frame 1 is mounted on the frame holder 4 (see FIG. 5) are provided on the outer peripheral sides of both sides of the frame 1. Lock release means 3 is provided above the holder 2.

As shown in FIG. 3, the holder 2 has a joint portion 2

An insertion portion 7 into which the glass plate 6 is inserted is provided below the main body 2b, and the insertion portion 7 is composed of the main body 2b and the back cover 8. The groove portion 7a of the insertion portion 7 is provided with the side surface inclined so that the groove portion 7a becomes shallower as it goes downward. Groove 7
A spherical body 9 made of a magnetic material is provided in a so as to be movable in the groove portion 7a. A sphere fixing member (sphere fixing shaft) 10 is provided above the groove portion 7a and is urged upward by a spring 11.

A magnet 12 for attracting and holding the sphere 9 is provided below the sphere fixing member 10. The spherical body fixing member 10 is provided so as to be movable up and down by the guide groove 2c and the pressing plate 13. A spring 11 is attached to the ball fixing member 10.
A C ring 14 is provided as a retaining member. The magnetic force of the magnet 12 is set to a magnetic force capable of attracting the sphere 9 only when the sphere 9 is considerably approached. Therefore, when the sphere fixing member 10 is located above due to the urging force of the spring 11, the sphere 9 is not attracted to the magnet 12, the sphere fixing member 10 is pushed downward, and the glass plate 6 is inserted into the insertion portion 7. The sphere fixing member 1 with the sphere 9 entering to the back is located above
When the distance between 0 and the sphere 9 approaches, the sphere 9
Are adsorbed.

As shown in FIG. 3 (b), the unlocking means 3 has a rod-shaped member 15 which comes into contact with the upper end of the spherical fixing member 10 protruding upward from each holder 2, and this rod-shaped member is a frame. It is formed in the same length as the side edge of 1. Two lock release shafts 16 are rotatably fitted to the rod-shaped member 15 (see FIG. 1). The unlocking shaft 16 is fixed in position by a bridge plate 17, and penetrates a sleeve 18 provided on the bridge plate 17. A pin 19 for fixing the lock releasing shaft 16 to the lock position is provided in the middle of the lock releasing shaft 16. The lock release shaft 16 is biased upward by a spring 22.

The sleeve 18 has a guide groove 20 as shown in FIG.
A hole 21 with a hole is provided. The lock release shaft 16 is inserted into the hole 21, and the pin 19 is inserted into the guide groove 20.
Has been inserted inside. When the unlocking shaft 16 is pushed in, the pin 19 projects downward from the guide groove 20. When the lock release shaft 16 is rotated and released in this state, the pin 1
9 contacts the lower surface of the sleeve 18, and the lock release shaft 16 is fixed in a state in which the lock release shaft 16 is pushed in against the biasing force of the spring 22.

FIG. 5 shows a frame holder 4 for placing the frame 1 while holding the glass plate 6,
Four struts 23 are provided on the base 41, and a hole 42 is provided in the central portion of the base 41. By fitting the engaging portion 5 provided on the frame 1 to the column 23, the frame 1 can be left in a state where the glass plate 6 is held by the holder 2.

The glass stand 24 shown in FIG. 6 is used as a glass holding member when the glass plate 6 is removed from the frame 1, and has a hole 24 at the center of the base 24b.
c is provided, and holding portions 24a for holding and holding the glass plate 6 are provided on both sides. Adjacent holder 2
The intervals between the grooves 4a are equal to the intervals between the holders 2, and the width of each groove is slightly larger than the thickness of the glass plate 6.

Next, the operation will be described. First, the glass plate 6 to be treated is inserted into the holding portion 24a provided on the glass stand 24 and leaned against it. When moving the glass plate 6 for cleaning, for example, the glass stand 2
4. Bring the frame 1 on the glass plate 6 leaning against 4, and lower the frame 1 while adjusting so that the glass plate 6 can be inserted into the insertion portion 7 of the holder 2. The glass plate 6 entering the insertion part 7 enters the insertion part 7 while pushing the sphere 9 upward. So when I lift the frame 1,
The glass plate 6 and the sphere 9 are pulled by gravity and move downward.
Since the groove portion 7a provided in the holder 2 is provided with the inclined side surface and becomes narrower as it goes downward, the glass plate 6 and the sphere 9 are sandwiched between the groove portion 7a and the wall of the insertion portion 7,
As a result, the glass plate 6 is clamped by the holder 2. If you move the frame 1 in this state, the glass stand 2
All the glass plates 6 leaning against 4 can be moved at once. In this state, the glass plate 6 is passed through each process while being held by the frame 1. For example, when the glass plate 6 is washed and dried, the support portion 23 of the frame holder 4 is fitted with the engaging portion 5 of the frame 1, and the glass plate 6 is attached to the frame 1.
In this state, the product is washed, dried, etc.

When removing the glass plate 6 from the holder 2, the frame 1 is brought onto the glass stand 24, and the glass plate 6 is inserted into the groove between the holding portions 24a provided in the glass stand 24. At this time, the position of the frame 1 is lowered with respect to the glass plate 6 due to the weight of the frame 1 so that the glass plate 6 can be inserted into the insertion portion 7.
Therefore, the sphere 9 moves upward in accordance with the movement of the glass plate 6.

Then, the lock releasing shaft 16 provided on the frame 1 side is pushed so that the pin 19 is projected below the sleeve 18. When the pin 19 comes out of the sleeve 18, the unlock shaft 16 is rotated so that the guide groove 20 provided in the sleeve 18 and the pin 19 are not parallel to each other. In this way, the pin 19 is attached to the sleeve 18
The lock release shaft 16 is fixed against the urging force of the spring 22 by being locked to the lower surface of the spring. Therefore, the rod-shaped member 1
Since 5 keeps the sphere fixing member 10 provided in the holder 2 pressed down, the magnet 12 provided in the sphere fixing member 10 comes close to the sphere 9 of the groove portion 7a and attracts the sphere 9 with magnetic force. Fix it. Therefore, the spherical body 9 cannot sandwich the glass plate 6 and the glass plate 6
Is released from the holder 2. Here, when the frame 1 is lifted up, the glass plate 6 is left on the glass stand 24, and only the frame 1 comes off.

[0016]

By using the holding device having this structure, the flat plate members can be clamped together by simply setting the frame from above a plurality of flat plate members, and when the clamps are released, a simple push is performed. Since it can be performed only by operation, work efficiency can be improved, and since the flat plate-shaped member is fixed via the spherical body, even a fragile object such as a glass plate can be easily held.
