Description

[0001] The present invention relates to a glass transfer guide apparatus using magnetic,

More particularly, the present invention relates to a substrate transfer guide apparatus using magnetic, and more particularly, to a substrate transfer guide apparatus using magnetic, in which a guide roller is supported by a magnet having the same polarity to be transferred, and the guide roller is rotatably fixed, And guide the substrate to be conveyed at a predetermined position by rotation of the guide roller, thereby preventing damage to the substrate and the guide roller.

In general, a flat panel display is manufactured through a process in which a substrate is transported through various processes. As described above, the substrate transfer guide apparatus is provided with a rotating roller which is arranged at regular intervals and is rotated by a driving source, and a rotary shaft is provided on the outer circumference of the rotating roller for transferring the substrate by frictional force with the substrate.

At this time, a guide roller for smooth conveyance of the substrate is disposed at a portion contacting both edges of the substrate. Accordingly, the substrate is guided by the guide rollers and is transported by the rotating rollers, and is subjected to various manufacturing processes.

Although there is no problem in that such a substrate conveying guide apparatus can manufacture a product while a substrate of a predetermined standard is conveyed by a conveying guide apparatus, in case of producing a multi-product of a flat panel display, It is necessary to provide a transferring device capable of transferring the image. In particular, when a conveying guide device capable of transporting one standard substrate is installed, another conveying line or a conveying guide device is required to manufacture a flat panel display of a different size, so that the entire conveying line needs to be replaced. As shown in Fig.

Accordingly, conventionally, a substrate conveying guide device capable of reducing the facility cost of a flat panel display and being able to improve productivity by being suitable for various kinds of production by allowing a substrate having various widths to be transferred in a conveying guide device for conveying a substrate .

The conventional technique includes a conveying means for conveying a substrate from a base, a width varying guide means for guiding the substrate conveyed in contact with both side edges of the substrate by the conveying means and adjusting the distance according to the width of the substrate The substrate transfer guide device includes:

When a substrate having a relatively small width is to be guided, the conventional substrate transfer guide apparatus having such a structure is configured such that when the height adjusting actuator is operated to move the first guide roller upward, one side of the substrate to be transferred is guided to the first guide roller So that the guide is brought into close contact. In the case of guiding a substrate having a relatively large width, one side of the substrate to be conveyed is brought into close contact with the second guide roller to guide the second guide roller when the height adjusting actuator is operated and the second guide roller is moved downward. In particular, in the case where the width variable guide means are arranged in pairs, it is possible to guide the transfer even if the substrate width is wider. Further, by rotating the rotary actuator, it is possible to guide the transfer of the substrate having the size ranging from the smallest to the largest width of the substrate width.

However, the above-described conventional technique does not transfer the substrate in a linear direction, but it sometimes occurs that the substrate is transported in a disordered state rather than being maintained in a linear direction while bouncing due to a phenomenon such as vibration during transportation. In this case, according to the prior art, as the edges or both end surfaces of the substrate are pressed against the guide rollers, a force is applied to the surface of the guide rollers, thereby causing damage such as scratches, which shortens the service life of the guide rollers.

Also, conventionally, as one or more substrates are continuously transferred, when a position of one of the substrates being transferred is deformed at a predetermined position, collision with a subsequent substrate or a front substrate occurs, and damage to the substrate can be prevented .

That is, the rotating roller 110 is rotated by driving the second motor 145 (see FIG. 7) to move the substrate 200 placed on the upper surface. At this time, the rotation holes 111 are fixed at one or more mutually spaced apart positions on the outer surface of the rotation roller 110 so that the rotation holes come into contact with the lower surface of the substrate 200 during the rotation of the rotation roller 110, Deliver power. Here, the rotation tool 111 moves the substrate 200 by a frictional force generated when the rotation tool 111 contacts one surface of the substrate 200.

Fig.

3 to 5, the guide member 130 includes one or more guide rollers 131, one or more guide rods 131a for supporting the guide rollers 131 to be rotatable, A coupling rod 135 which is erected at the lower end of the guide plate 132 to be coupled to the support member 120 and which is installed on the coupling rod 135; A bearing 136 for supporting the guide plate 132 and the guide rod 131a to be rotatable in the left and right direction, a support plate 133 fixed to a side surface of the support member 120, And a magnetic plate 134 having the same polarity at the side end faces mutually opposed at the guide plate 132.

The guide roller 131 is rotatably fixed at the front end of the guide rod 131a and rotatably supported on the rotary roller 110 by one or more of the guide rollers 131 ', 131' ', 131' '' Thereby supporting the side surface of the substrate 200 to be transported.

The guide rod 131a is fixed to the upper surface of the guide plate 132 so as to stand upright, and supports a guide roller 131 fixed to the end of the guide rod 131 to be rotatable.

Here, the guide rollers 131 and the guide rods 131a are shown to be installed between the rotating rollers 110 in a group of three from the upper surface of the guide plate 132. However, according to the intention of the operator or the designer And one guide roller 131 may be installed between the rotating rollers 110. This can be modified by various applications of the designer.

The guide plate 132 supports the guide rod 131a on an upper surface thereof and has a magnetic plate 134 having one polarity selected from positive and negative polarities at one side thereof facing the support member 120 ) Is installed.

The coupling rod 135 extends vertically from the lower surface of the guide plate 132 and is coupled to a screw hole formed at an end of the coupling member 135 so as to be coupled to a screw hole formed on an upper surface of the horizontal frame 122 of the support member 120. (135a) is formed. That is, the coupling rod 135 is coupled to the horizontal frame 122 of the support member 120 to fix the guide rods 131a to 132.

The bearing 136 is installed at an end of the coupling rod 135 to support the guide plate 132 so as to be rotatable in the left-right direction. The rotation of the guide plate 132 by the bearing 136 will be described later with reference to FIG.

The support plate 133 is attached to one side of the support member 120 (for example, a side surface of the vertical frame 121 opposed to the magnetic plate 134 of the guide plate 132) A magnetic plate 134 having the same polarity as that of the magnetic plate 134 provided in the magnetic disk 132 is provided. The support plate 133 is fixed to one side of the vertical frame 121.

The magnetic plate 134 includes first and second magnetic plates 134a and 134a 'and first and second magnetic plates 134b and 134b' which have the same polarity on opposite sides of the guide plate 132 and the support plate 133, Respectively.

Here, the first and second magnetic plates 134a and 134a 'and the second magnetic plates 134b and 134b' have the same polarity as a pair of mutually spaced apart. That is, the first magnetic plates 134a and 134a 'are a pair fixed to opposite ends of the side surface of the guide plate 132, respectively, and the second magnetic plates 134b and 134b' Which are fixed to one side and the other side, respectively, The first and second magnetic plates 134a and 134a 'and the second magnetic plates 134b and 134b' are fixed to the guide plate 132 and the support plate 133 at positions facing each other.

For example, when the guide roller 131 is rotated in one direction by the bearing 136, magnetic poles 134a, 134a, 134b, and 134b 'of the same polarity placed at the corresponding positions As they come into close contact with each other, a pushing force is applied. That is, when the guide plate 132 is rotated by the rotation of the bearing 136, a force pushing the magnetic plate of the same polarity is applied to rotate the guide plate 132 in the magnetic plate 134 .

Here, the guide roller 131 and the rotary roller 110 may be driven by respective motors 144 and 145 as shown in FIG. For example, the guide roller 131 is rotated by a rotational force transmitted by the first motor 144 (see FIG. 7) driven by the control of the controller 142, and the rotation roller 110 is rotated by the controller 142 The second motor 145 driven by the control of the second motor 145 to be transferred to the upper surface of the substrate 200 in one direction.

7), the first motor 144 and the second motor 145 (see FIG. 7) may be connected to the input unit 141, And rotates the rotation roller 110 and the guide roller 131. [

3 to 5, when the guide roller 131 is rotated by a frictional force with the substrate 200, the guide roller 131 is rotated at the tip of the guide rod 131a And the guide rod 131a is fixed to the guide plate 132 in an upright shape.

Alternatively, the guide roller 131 may be integrally formed with the guide rod 131a and rotated by the rotation of the guide rod 131a. The integrated structure of the guide roller 131 and the guide rod 131a may be provided to rotate the guide roller 131 by the first motor 144. That is, the guide roller 131 rotates as the guide rod 131a connected to the rotation shaft of the first motor 144 rotates to guide and convey the side surface of the substrate 200. The construction of the connection between the motor and the guide roller 131 is the same as that of the related art.

The substrate conveying and guiding apparatus 100 using the magnet according to the present invention may display the driving state of the rotating roller 110 and / or the guide roller 131 in a luminous state so that the operator can recognize the driving state of the rotating roller 110 and / It is preferable that the display device further comprises a display unit 143 composed of any one of a display for indicating that the display is being driven as a character or a symbol.

When the operator applies a drive command through the input unit 141, the first motor 144 and the second motor 145 are driven to drive the rotating roller 110 and the guide roller 131. Therefore, when the substrate 200 is transferred from the input side of the rotation roller 110, the substrate 200 is transferred in one direction by a frictional force between the rotation roller 110 and one or more rotation holes 111 spaced from each other.

At this time, the guide rollers 131 are closely attached to both sides of the substrate 200 to support the substrate 200 in a forward direction without disturbance. The guide roller 131 may be rotated by the first motor 144 to guide the substrate 200 or may not be driven by the first motor 144, So that the substrate 200 can be guided.

At this time, the substrate 200 may be disturbed in one direction rather than in a proper position due to a phenomenon of being vibrated due to vibration or other causes while being conveyed in one direction by the rotation roller 110 and the rotation tool 111. This will be described with reference to Figs. 6A and 6B.

FIG. 6A is a plan view showing an example in which the guide member 130 is rotated in one direction in the substrate transfer guide apparatus 100 using magnetic according to the present invention, FIG. 6B is a plan view showing a guide member 130 rotated in one direction, And is restored to its original position by a repulsive force by the elastic member 134. As shown in FIG.

6A and 6B, it is assumed that the substrate 200 is twisted to one side instead of being oriented in the forward direction. In this case, a first guide (not shown) installed at one end of the guide roller 131, A force is applied to the side surface of the roller 131 'as the substrate 200 is twisted.

Accordingly, the guide plate 132 is rotated by the bearing 136 when a lateral force is applied to the first guide roller 131 '. Therefore, the first guide roller 131 'is rotated backward from its original position, and the third guide roller 131' '' is moved forward. The first magnetic plate 134a fixed at the corresponding one of the first magnetic plates 134a and 134a 'provided at one end surface of the guide plate 132 and the second magnetic plate 134b of the support plate 133, The repulsive force is generated due to the same polarity.

That is, the guide plate 132 is rotated in one direction by a force applied laterally by the substrate 200, and the first magnetic plate 134a and the second magnetic plate 134b are in close contact with each other, And is rotated in the home position by the repulsive force.

Therefore, the position of the substrate 200 is corrected so as to be oriented in the forward direction by the force applied while the guide plate 132 is rotated in the reverse direction.

Therefore, even if the substrate conveyed by the magnetic guide according to the present invention is stuck on the guide roller due to the occurrence of a disordered state in which the continuously transferred substrate is generated during the conveying process, the force due to the collision of the substrate is absorbed And at the same time, the substrate can be pressed and restored by the repulsive force of the same polarity of the magnetic plate. Therefore, it is possible to prevent the guide roller and the substrate from being damaged during transfer of the substrate, and to prolong the service life of the guide roller.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
