[Technical field of design]

The present invention relates to an ejection device of a liquid crystal display (or LCD) module, and in particular, a process in which an assembled LCD module is separated from a pallet transported on a conveyor and unloaded is performed by a worker's manual operation. The present invention relates to an ejection device for an LCD module, which can be performed by an automated device without using the present invention.

[Prior art]

In general, a liquid crystal display uses a dielectric anisotropy of a liquid crystal in which the arrangement direction of the liquid crystal is changed by a voltage applied from the outside and the light reflection property is changed. It is a flat panel display that displays any icon.

In such a liquid crystal display, ITO (Induim Tin Oxide) transparent electrodes are formed on inner surfaces of two transparent glass substrates arranged in parallel to each other, and an alignment film defining dielectric anisotropy of the liquid crystal is stacked thereon. The liquid crystal is injected and sealed between the glass substrates thus formed.

In the TFT-LCD of which the ITO transparent electrode is an active matrix driving method, the TFT and the pixel electrode are arranged on the lower glass substrate, and the color filter and the common electrode are formed on the upper glass substrate.

In addition, a polarizing plate for linearly polarizing the light of the backlight is attached to the outer surfaces of the two glass substrates in order to obtain the effect of the display.

In the case of a TFT-LCD, such a liquid crystal display is formed by repeatedly performing deposition, photolighography, and etching on a lower glass substrate to form a TFT and a pixel electrode, and an upper glass on which a black mattress is formed. Forming a color filter layer and a common electrode on the substrate, sealing the upper and lower glass substrates formed as described above, injecting and encapsulating liquid crystal therebetween to form an LCD cell, and processing the signal of the LCD cell. In order to manufacture a module by mounting a circuit unit and attaching a backlight and a device.

The liquid crystal display is continuously and sequentially transferred to each process by the conveyor while the glass substrate, the LCD cell and the LCD module are seated on the pallet during the manufacturing process.

[Technical Challenges to be Done]

In the above-described manufacturing process of the liquid crystal display, the assembled LCD module is transported while seated on the pallet, and after visual inspection (process of checking the defects by the eyes by the operator directly with the LCD cell turned on) is performed. It is separated from the pallet by an operator and shipped to the product after the final visual inspection is performed.

However, in the ejection process of the LCD module as described above, since all the processes are performed by the manual labor of the operator in the related art, there is a problem of causing unnecessary operator input, resulting in increased labor and manufacturing costs.

In order to solve the problems of the prior art, the present invention is to reduce the labor cost and manufacturing cost by allowing the ejection process of the assembled LCD module to be performed by an automated device, not by the manual operation of the operator. I want to realize it.

[Configuration and Action of Design]

In order to achieve the above object, this invention proposes an ejecting device of a liquid crystal display module realized by the following means.

That is, the ejection device of the liquid crystal display module of the present invention is a conveyor which transfers the pallet with the LCD module set to the ejecting process or returns the empty pallet after the LCD module is ejected, and is selectively selected in front of the pallet transported by this conveyor. And a stopper for protruding the pallet to stop at the eject position, and lifting the LCD module seated on the pallet while being vertically lifted in the conveying direction of the pallet, and moving in parallel to the conveying direction of the pallet. Characterized in that the pickup means for placing the LCD module on the conveyor to be moved.

The pickup means is composed of a suction pad that sucks the LCD module under vacuum pressure. Further, the pickup means is constituted by a pickup hand that lifts the LCD module while being opened or improved by the driving unit.

According to this configuration, the ejection process of the assembled LCD module is automatically performed without the manual labor of the operator. Therefore, this design can prevent the unnecessary member from being put in and reduce the labor cost and manufacturing cost.

EXAMPLE

EMBODIMENT OF THE INVENTION Hereinafter, one preferred embodiment which implements this invention is demonstrated in detail based on an accompanying drawing.

1 is an overall perspective view showing an ejecting device of the liquid crystal display module according to this embodiment.

In this embodiment, a device is manufactured by assembling a circuit part and a backlight in an LCD cell, manufacturing an module, performing an aging and visual inspection, and then separating the LCD module transferred to the eject process from the pallet.

In the drawings, reference numeral 1 denotes a device in which the pallet 2 on which the LCD module is set is a conveyor 3 for moving the pallet 1, which performs visual inspection of the LCD module. The LCD module 4 set on the upper side of the pallet 3 is conveyed by the conveyor 2 to the ejection process via the visual inspection apparatus 3.

The ejection apparatus according to this embodiment includes a stopper 5 which is installed in front of the pallet 1 conveyed by the conveyor 3 and selectively protrudes to stop the pallet 1 at the eject position. In addition, the pickup means for moving only the LCD module 4 to the upper side of the conveyor 6, which is moved up and down in parallel to the traveling direction of the pallet 1 in the vertical direction or moved in parallel to the next process, for example, the final visual inspection process. It includes.

Here, the pickup means is a suction pad (7) for sucking the LCD module (4) seated on the pallet (1) with a vacuum pressure, and the LCD module (4) is operated by the drive unit in the state in which the LCD module (4) is the LCD module (4) It consists of a lifting plate 9 provided with a pick-up hand 8 which lifts up and down both sides of the bottom end.

The suction pad 70 is connected to an air compressor (not shown) by a check tube 10, and a vacuum sensor 11 is installed in the middle of the driving unit, wherein the driving unit opens or narrows the width of the pickup hand 8. It consists of the cylinder 12.

In addition, the pick-up means includes a Y-axis transfer 14 having an air cylinder 13 as a drive unit for allowing the above-mentioned lifting plate 9 to move up and down, and the Y-axis transfer 14 is in a horizontal direction. It consists of an X-axis transfer (15) having a drive to move to. The Y-axis transfer 14 guides the movement of the elevating plate 9, and the X-axis transfer 15 guides the movement of the Y-axis transfer 14, respectively.

In this case, a more detailed structure of the drive unit for moving the Y-axis transfer 14 is shown in FIG. 2, which is a motor 16 as a power source and a timing belt driven by the motor 16. As shown in FIG. 17). That is, the Y-axis transfer 14 attached to the timing belt 17 and one body by the driving of the motor 16 is guided to the X-axis transfer 15 and moved in the horizontal direction.

The operation state of the eject apparatus of this embodiment having such a configuration will be described later.

After the visual inspection, the pallet 1 moved by the conveyor 2 is stopped by the stopper 5 at the eject position of the LCD module 4. Subsequently, the air cylinder 13 of the Y-axis transfer 14 is sucked by the vacuum pressure of the suction pad 7 provided in the lifting plate 9. The LCD module 4 thus adsorbed is further supported by the pick-up hand 8 which is operated by the signal of the vacuum sensor 11 and is lifted by the raising operation of the air cylinder 13.

The LCD module 4 supported in this way is transferred in the horizontal direction as the Y-axis transfer 14 is moved by the motor 16 and the timing belt 17 and guided by the X-axis transfer 15. This operation is stopped at the upper side of the conveyor 6, and the LCD module 4 is placed on the upper surface of the conveyor 6 in the reverse order of the pick-up operation. The conveyor 6 transfers the LCD module 4 to the final visual inspection process.

On the other hand, the conveyor 2 in which the pallet 1 is installed returns an empty pallet again.
