Description

Transfer device

The present invention relates to a conveying apparatus, and more particularly, to a conveying apparatus for driving the roller shaft by directly connecting the roller shaft of the conveying unit and the motor shaft of the driving unit.

In general, a liquid crystal display (LCD) glass manufacturing process uses a conveying device for conveying glass. The conveyed material conveyed by such a conveying device includes the aforementioned LCD glass, a flat panel display (FPD), a solar cell, and the like. An optical panel and other flat conveyances may be included, but for the sake of convenience, hereinafter, "LCD glass" will be described as an example of the object to be transported.

As is well known, an LCD injects a liquid crystal, which is an intermediate of a solid and a liquid, between two thin upper and lower glass substrates, and changes the arrangement of liquid crystal molecules by an electrode voltage difference between the upper and lower glass substrates (hereinafter referred to as "LCD glass"). It is a device using a kind of optical switch phenomenon that generates a contrast and displays a number or an image. Currently, these LCD technologies are widely used in electronic clocks, electronic devices such as electronic calculators, TVs, notebook PCs, speed displays and driving systems of automobiles and aircrafts.

In particular, LCD TVs and monitors using the LCD technology have been mainstream in sizes of 20 to 30 inches and 17 inches, respectively, but recently, preference for large LCD TVs of 40 inches or more and large monitors of 20 inches or more is increasing. Therefore, manufacturers of LCDs have come to produce wider LCD glass.

On the other hand, such LCD glass has brittleness which is very vulnerable to the impact applied from the outside. Therefore, if the LCD glass can be efficiently stored and transported from the pre-process step to the post-process step of manufacturing the LCD glass without being damaged, it will not only improve productivity but also maintain the flat display quality. Definitely

In particular, as described above, as the size of the LCD glass, which is enlarged as in the recent trend, becomes larger in size and thinner, special care is required in storing and transporting the LCD glass.

In order to transfer the LCD glass, a conveying apparatus using a roller capable of conveying the LCD glass more safely and quickly is used.

However, such a conventional conveying device, a gear for power transmission or a magnet is configured at one end of the roller shaft passing through the roller so as to rotate like a roller, this gear system is due to friction during rotation of the gear means Fine dust such as dust may be generated, and the magnet method has a disadvantage in that it is not suitable for the transfer of LCD glass to be enlarged due to the weight limit for the object to be transferred.

Accordingly, the present invention has been made to solve the problems of the prior art as described above, by directly connecting the motor shaft of the motor to one end of the roller shaft, to quickly transfer the large LCD glass while minimizing the generation of fine dust Its purpose is to provide a conveying device that can be used.

The motor shaft and the coupling groove are preferably coupled by any one of a key coupling, a spline coupling, or a serration coupling.

In addition, the roller shaft is installed at both ends of the frame through the bearing, the frame is provided with a cover surrounding the motor, the motor is preferably composed of a brushless DC (BLDC) motor.

According to the conveying apparatus of the present invention, the motor is directly connected to the roller shaft to rotate the roller shaft to obtain a rapid response force of the roller shaft as well as a large force rotational force, which can quickly and safely transport the large LCD glass In addition, since there is no power transmission gear or magnet, there is an effect that can suppress or minimize the occurrence of fine dust.

In addition, according to the present invention, since the motor and the roller shaft are key coupling, spline coupling, or serration coupling, the driving force of the motor can be transmitted to the roller shaft side stably while being stable.

In addition, according to the present invention, the roller shaft can be smoothly rotated on the frame by the bearing, and in addition to preventing dust and the like from penetrating into the motor by the cover in advance, there is an advantage that can also block the noise of the motor. .

In addition, in the present invention, by using a brushless motor, the heat generation is less and the efficiency of the motor is improved, and since there is no physical brush contact, it is possible not only to secure a constant rotational force but also need to replace the brush, so the durability is good. It can be used semi-permanently.
