The present invention relates to a separate type LCD frame crunching automation facility using a high-speed shuttle shuttle loader (Gantry Shuttle Loader) that is automated to manufacture a dedicated equipment.

Recently, with the development of information processing apparatuses, the demand for display apparatuses serving as an interface between a user and the information processing apparatus is increasing rapidly.

In particular, the development of high definition television (High Definition Television) is complete, and the importance of the display device in the process of improvement is being studied more.

Types of display devices are known as color cathode ray tube (CRT), liquid crystal display (LCD), fluorescent display (VFD), plasma display (PDP), organic EL (OLED) and the like.

However, as a display element satisfactory in relation to the development of high-definition television, which has not been technically completed yet, such display devices have been developed while maintaining mutually complementary relations at different positions.

Among the display devices described above, the liquid crystal display device and the plasma display device, which have recently been improved in performance, will be described.

First of all, the liquid crystal display device displays information by using the electrical and optical properties of the liquid crystal material injected into the liquid crystal display panel. Recently, as a monitor and image display device of a television and a computer, a portable video camera, a digital camera, a vehicle Applications such as navigation devices, various informatization devices and communication devices are gradually expanding.

The liquid crystal display device as described above requires a liquid crystal display panel assembly that receives an image signal from an information processing device and converts the signal into a liquid crystal control signal and then controls the amount of light transmitted through the liquid crystal to visually recognize the electrical image signal. Shall be.

The liquid crystal display panel assembly is again connected to a liquid crystal display panel for displaying an image using liquid crystal, a printed circuit board for applying an electrical signal to the liquid crystal display panel, and the liquid crystal display panel and the printed circuit board, It includes a flexible circuit board to reduce the planar area.

In addition, since the liquid crystal display uses liquid crystal, which is a light-receiving element that does not emit light by itself, the liquid crystal display device requires a backlight assembly installed on the lower surface of the liquid crystal display panel assembly in addition to the liquid crystal display panel assembly to provide light to the liquid crystal display panel assembly. do.

The above components are housed in a case for protection and fixation from external impact, and the bottom of the case sequentially receives the components of the backlight assembly, and above the liquid crystal display panel assembly.

Next, the plasma display apparatus displays an image on a plasma display panel (PDP) using a plasma generated by gas discharge. After the gas is sealed between two electrodes installed in an enclosed space, A discharge voltage is applied and the phosphor layer formed in a predetermined pattern is excited using ultraviolet rays generated due to the discharge voltage to obtain a desired number, letter or image.

Such a plasma display apparatus basically includes a PDP, a chassis base disposed substantially parallel to the PDP, a heat conducting medium interposed between the PDP and the chassis base and closely contacted to the PDP and the chassis base, and a panel of the chassis base. And a driving circuit mounted on the opposite side of the attachment surface and connected to the PDP to drive the PDP. A front case is coupled to the PDP side, and a back case is coupled to the driving circuit side.

The plasma display device has the most promising resolution and illuminance ratio in this field, and is not only fast in response, but also suitable for displaying a large area image, and is widely used in televisions, monitors, indoor and outdoor display panels, and the like. have.

The chassis is installed to support the outside of the display panel assembly. The chassis is divided into a top chassis and a bottom chassis according to the front and rear positions of the display panel assembly. The top chassis is mainly made of aluminum alloy or stainless steel (SUS). Or it is made of metal materials such as EGI steel sheet, galvalume steel sheet, and in the case of the bottom chassis is made of metal materials such as electro-galvanized steel sheet (EGI).

For example, the top chassis protects and reinforces the LCD liquid crystal and the backlight unit, and serves to prevent the separation of various panels that are components of the backlight unit.

In particular, LCD frames such as LCD top chassis or LCD case tops are made of separate material and then manufactured in the form of one completed LCD frame through a predetermined assembly process.

Currently, the production of the LCD frame is dependent on the manual work using a press, etc., the work efficiency is not greatly reduced, such as the amount of work does not come out, there is a limit in improving workability and productivity.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 to 3 show the overall structure of the automated equipment for manufacturing an LCD frame according to the present invention.

As shown in Figures 1 to 3, the lower part of the frame structure 100 forming the overall skeleton of the automation equipment is provided with a component supply unit 10 for supplying the parts in the front, the upper clinching work to the rear The primary clinching unit 20 for performing the second, the second clinching unit 30 for performing the side clinching operation, the product discharge unit 50 for discharging the finished product is arranged in sequence.

In addition, the upper part of the frame structure 100 is disposed with a component transfer part 40 for moving the parts between the processes, the component transfer part 40 at this time is operated along the trajectory parallel to the X-axis direction, that is, the direction in which the component proceeds It also serves to transfer components between neighboring processes.

Therefore, the part put into the component supply part 10 by the operator passes through the first clinching part 20 and the second clinching part 30 in turn, and the two clinching operations, that is, the upper clinching operation and the side clinching operation After receiving the clinching work, the product is finally discharged through the product discharge part 50, thereby completing one cycle related to the production of one LCD frame.

At this time, the component supply unit having the reciprocating movement in the X-axis direction and the reciprocating movement in the vertical direction as the operation mechanism is the transfer of the components between the component supply unit 10, the clinching unit 20, 30, the product discharge unit 50 Made by 40.

Of course, parts supply, two clinching operations, product discharge, etc. are performed at the same time in each process step, one cycle for one LCD frame production can be carried out in a continuous process.

The clinching operation performed by the primary clinching unit 20 and the secondary clinching unit 30 is a pressing operation of a flexible plastic material including a metal plate. The die side has a button shape and the punch side is pushed. It is a joining method to form a groove, and is a joining method commonly used when joining two or more metal plates.

The overall process including supply of parts, transfer of parts, clinching operation, and product discharge in such an automated facility is performed for the operation of each actuator means such as a cylinder using signals of various sensors (not shown) as input signals. It is linked and automatically performed by a controller (not shown) that outputs a control signal, and a cooperative control method between these processes, for example, a method of operating a component conveying part when supplying parts or completing a clinching operation, and a clinching operation The method of operating the clinching means in setting the part in the region and the like can be adopted without particular limitation as long as it is a method commonly known in the art.

4 to 6 shows the structure of the component supply unit in the automated device for manufacturing an LCD frame according to the present invention.

4 to 6, on the upper surface of the base plate 13, a component loading jig 15 made of four combinations is arranged in a rectangular frame structure.

At this time, the component loading jig 15 is a place where each of the four separate components constituting the rectangular LCD frame is placed one by one, and has a substantially rectangular cross section that can overturn a component having a "b" shaped cross section. It consists of a long rod structure.

Therefore, when a worker puts a single part on each component loading jig 15 arranged in a rectangular frame structure, each part takes a single rectangular frame shape as a whole.

In addition, three of the four component loading jigs 15 arranged in a rectangular frame structure except the one fixedly installed are provided with respective clamping devices 14 that are movable in the X-axis and Y-axis directions. When moving for parts supply, the product can be supported without shaking.

For example, among the two component loading jigs 15 arranged in the X-axis direction and the two component loading jigs 15 arranged in the Y-axis direction, the clamping block / plate 17 is disposed on the rod. Each of the air cylinders (16) having a) is assigned to one by one so as to be able to press and hold the components on the component loading jig (15) through the clamping block / plate (17) during operation of the air cylinder (16).

At this time, the component loading jig 15 and the air cylinder 16 are installed on the base plate 13, and the clamping block / plate 17 is installed on the base plate 13 in two rows of LM guides ( 12b) is slidably supported and simultaneously connected to the rod of the air cylinder 16, the clamping block / plate 17 moves in the respective X and Y axis directions when the air cylinder 16 is operated. I can catch you.

In particular, the base plate 13 is capable of moving between the position where the operator can place the component and the position where the component transfer part 40 can pick up the component.

That is, the entire base plate 13 and the component loading jig 15 installed thereon can be reciprocated for a certain period in the X-axis direction, and thus the operator can conveniently place the component on the component loading jig 15. Can be obtained.

To this end, two rows of LM guides 12a and rodless cylinders 11 therebetween, which are supported on the frame structure 100 and arranged long in the X-axis direction, are installed at the bottom of the base plate 13. Since the movable block (not shown) of the rodless cylinder 11 is connected to the bottom of the base plate 13, the base plate 13 guides the LM guide 12a together with the operation of the rodless cylinder 11. It can move a certain section in the X-axis direction.

Therefore, the worker loads each part on the part loading jig 15 while the part loading jig 15 is positioned outside (front) of the frame structure 100 by the movement of the base plate 13. When loading, at the same time, the respective components are fixed by the operation of the clamping device 14, and then the entire base plate 13 on which the components are loaded by the operation of the rodless cylinder 11 is frame structure 100. When moved inward, the clamping device 14 is unclamped, and at the same time, each component on the component loading jig 15 is picked up and taken in a rectangular frame shape by the component transfer part 40 waiting at the upper portion thereof. One step for the supply of parts is completed.

After the parts supply, the base plate 13 is returned to the initial position for component loading by the operation of the rodless cylinder 11 again.

7 to 9 show the structure of the first clinching unit in the automated equipment for manufacturing an LCD frame according to the present invention.

As shown in FIGS. 7 to 9, the primary clinching unit 20 performs an upper clinching operation on a component provided from the component supply unit 10, that is, joining two components overlapping each other from above and below. In this case, a total of four upper clinching operations are performed on one LCD frame.

To this end, two pairs of primary clinching devices 24 are arranged in a square symmetrical structure with the jig plate 21 positioned at the center while being supported on the frame structure 100.

That is, four primary clinching devices 24 are arranged in proximity to each corner region of the jig plate 21.

At this time, the jig plate 21 is disposed in a rectangular frame structure similar to the jig 15 for the component loading above.

The primary clinching device 24 is installed in a vertical posture on a vertical plate 28a capable of vertical movement while being supported by a guide means such as a guide rail on the post structure 28c. 28a is connected to the rod of the up / down cylinder 23 installed on the upper part of the post structure 28c, and when the vertical plate 28a moves upward or downward by the operation of the up / down cylinder 23, The primary clinching device 24 assembled on the vertical plate 28a also moves up and down together.

The up and down movement of the primary clinching device 24 is to avoid interference when entering and positioning the component side for the clinching operation.

In addition, a stopper means is provided on the vertical movement trajectory line of the vertical plate 28a to control the movement distance.

In addition, the whole post structure 28c including the primary clinching device 24 is supported on the upper base plate 29a so that the whole can move for a predetermined section in the Y-axis direction.

That is, when the component is loaded on the jig plate 21, the component is spaced apart from the jig plate 21 side to exclude the interference, and then moved back inward after completing the component loading to perform the clinching operation.

To this end, a forward / reverse cylinder 22 is installed at a side portion of the upper base plate 29a, and the cylinder rod at this time supports a horizontal plate supporting the post structure 28c including the primary clinching device 24. It is connected with (28b) side.

Accordingly, with the operation of the forward / reverse cylinder 22, the entire primary clinching device 24 and the post structure 28c may move away from the jig plate 21 side while moving in the Y-axis direction, and again the jig plate ( 21) can come close to the side to come to the position for clinching work.

At this time, the horizontal plate 28b may be installed in a slidable structure on the upper base plate 29a through a guide means such as a guide rail.

In addition, two pairs of primary clinching devices 24 constituting the primary clinching portion 20, that is, four primary clinching devices 24 are paired with each other and move in the X-axis direction to be separated from each other. It can be built or narrowed.

To this end, at the bottom of the upper base plate 29a on which each clinching device 24 is mounted, a screw device 25a, for example, a ball screw transmission device, is arranged to extend in a lengthwise manner between two plates. It is provided in a structure that is supported at both ends by a bearing or the like provided on the upper surface of the base plate 29b, and the slider portion of the screw device 25a installed in this way is coupled to the upper base plate 29a side, and the screw device by handle operation By operating 25a, the two upper base plates 29a, that is, the primary clinching devices 24 mounted thereon, can be opened or narrowed while simultaneously moving with each other through ball screw transmission.

In addition, the LM guide 26a which is provided on the lower base plate 29b on both sides with the screw device 25a interposed therebetween moves the clinching device 24 and substantially the clinching device ( It is possible to guide the movement of the entire upper base plate (29a) including 24.

At this time, the slider portion coupled to each upper base plate 29a side is coupled with the screw portion of the screw device 25a to be opposite to each other, so that the two upper base plates 29a face each other. The gap can be widened in the direction of narrowing or moving away.

Thus, the position of two pairs of clinching devices can be adjusted in the X-axis direction, and thus there is an advantage in that it can actively cope with changing LCD frame specifications, specifications, or the thickness of the frame material.

In addition, the primary clinching unit 20 includes a means for adjusting the position in the Y-axis direction as well as the X-axis position adjustment above.

In this case, one pair of the two pairs of primary clinching devices 24 may adopt a method of fixing the position and moving the remaining one pair of positions.

To this end, a screw device 25b and an LM guide 26b, which are supported on the frame structure 100 and extended in the Y-axis direction, are disposed at the bottom of the lower base plate 29b, and the screw device 25b at this time is disposed. The slide portion of is coupled to a bar-shaped member connected across two lower base plates 29b, and thus, the pair of primary clinching devices 24 are similarly operated in the Y-axis direction by operating the handle. It is possible to adjust the distance from the other pair of primary clinching device 24 is fixed by moving the position.

In addition, the primary clinching unit 20 is provided with a clamping device 27 that can hold at least four parts of the component during the clinching operation, wherein the clamping device 27 is a part loading using a rotating structure It can grasp the parts effectively during clinching operation while avoiding the interference of time.

Here, the primary clinching device 24 may apply a common clinching device and a general clinching method composed of a punch means, a die means, and an actuator capable of providing a pressing force to the punch means.

Therefore, when the parts are conveyed from the component supply part 10 by the component conveyance part 40 in the state which four primary clinching apparatuses 24 are separated from the jig plate 21, and are loaded on the jig plate 21, By the operation of the forward / reverse cylinder 22, each primary clinching device 24 approaches the jig plate 21 side and is positioned in the clinching work area, and then continues to operate the lift / lower cylinder 23. As a result, the primary clinching device 24 is close to the clinching work part of the part, and at the same time, the upper clinching work on the part is performed through the operation of the primary clinching device 24.

On the other hand, after completion of the primary clinching operation for joining the upper parts of the parts, each primary clinching device 24 is returned to the initial position by the reverse order of the operation of each cylinder.

10 to 12 shows the structure of the second clinching unit in the automated equipment for manufacturing an LCD frame according to the present invention.

As shown in FIGS. 10 to 12, the secondary clinching unit 30 performs side clinching operations for the parts that have completed the upper clinching operation, that is, joining two overlapping parts from the left and right sides. Here, a total of four side clinching operations are performed on one LCD frame.

For this purpose, two pairs of four secondary clinching devices 33 in total are arranged in a square symmetrical structure with respect to the jig plate 31 positioned at the center while being supported on the frame structure 100.

That is, four secondary clinching devices 33 are disposed in proximity to each corner region of the jig plate 31.

The secondary clinching device 33 is installed on the upper base plate (37a) while being supported by a guide means such as a guide rail and installed in a horizontal attitude to the vertical plate 38 that can be moved back and forth in the X-axis direction. In this case, the vertical plate 38 is connected directly to the rod of the forward / reverse cylinder 32 installed on the upper base plate 37a directly below the secondary clinching device 33, so that the forward / reverse cylinder 32 When the vertical plate 38 is moved forward or backward by the operation of), the secondary clinching device 33, which is integrally assembled on the vertical plate 38, moves back and forth together with the jig plate 31. It can be approached or separated from the component side being loaded.

That is, when parts are loaded on the jig plate 31, the parts are separated outward from the jig plate 31 side in order to exclude interference, and then the inside of the jig plate 31 is moved again to perform the clinching operation.

Accordingly, with the operation of the forward / reverse cylinder 32, the entire second clinching apparatus 33 and the vertical plate 38 may be moved away from the jig plate 31 side while moving a certain section in the X-axis direction, and again. The jig plate 31 can be brought into proximity to the position for clinching operation.

In addition, a stopper means is provided on the vertical movement trajectory line of the vertical plate 38 to control the movement distance.

In addition, the two pairs of secondary clinching devices 33 constituting the secondary clinching portion 30, that is, the four secondary clinching devices 33 each have a structure capable of moving in the X-axis direction.

To this end, at the bottom of the upper base plate 37a on which each clinching device 33 is mounted, a screw device 34a, such as a conventional ball screw transmission device, is disposed in a long form, and at the same time, the screw device ( 34a is installed in a structure that is supported at both ends by a bearing or the like installed on the upper surface of the lower base plate 37b, and the slider of the screw device 34a thus installed is coupled to the bottom surface of the upper base plate 37a. By operating the screw device 34a by the handle operation, the upper base plate 37a, that is, the secondary clinching device 33 mounted thereon, can be moved in the X-axis direction through ball screw transmission, and eventually face each other. The gap between the pair of secondary clinching devices 33 can be adjusted as necessary.

In addition, the LM guide 35a, which is installed on the lower base plate 37b with the screw device 34a interposed therebetween, moves the secondary clinching device 33, and is substantially secondary. It is possible to guide the movement of the entire upper base plate 37a including the clinching device 33 and the vertical plate 38.

As the two clinching devices of one pair can be adjusted in the X-axis direction, there is an advantage in that the LCD frame can be proactively coped with when the LCD frame specifications, specifications, or the thickness of the frame material change.

In addition, the secondary clinching unit 30 includes a means for adjusting the position in the Y-axis direction as well as the X-axis position adjustment above.

In this case, one pair of the two pairs of secondary clinching devices 33 may adopt a method of fixing the position and moving the remaining one pair of positions.

At this time, unlike the primary clinching unit 20 which simultaneously moves a pair of primary clinching devices 24, in the case of the secondary clinching device 33, each clinching device 33 constituting a pair is individually Adopt a way of moving.

To this end, a screw device 34b extending on the Y-axis direction while being supported on the frame structure 100 and a LM guide 35b on both sides thereof are disposed at the bottom of the lower base plate 37b, and the screw device at this time is disposed. Since the slide portion of 34b is coupled to the lower base plate 37b side, the other one that is fixed by moving the pair of secondary clinching apparatuses 33 in the Y-axis direction similarly to the above by operating the handle. The interval with the secondary clinching device 33 of the pair can be adjusted.

In addition, the secondary clinching unit 30 is provided with a clamping device 36 that can hold at least four parts during the clinching operation, wherein the clamping device 36 is a part loading using a rotating structure It can grasp the parts effectively during clinching operation while avoiding the interference of time.

Here, even in the case of the secondary clinching device 33, a general clinching device and a general clinching method composed of a punch means, a die means, and an actuator capable of providing a pressing force to the punch means can be applied. .

Therefore, the parts which finished the upper clinching operation by the component transfer part 40 in the state which four secondary clinching apparatuses 33 are separated from the jig plate 31 are conveyed from the primary clinching part 20, and the jig plate is carried out. When loaded onto the (31), by the operation of the forward / reverse cylinder 32, each secondary clinching device 33 approaches the jig plate 31 side and is positioned in the clinching work area while continuing to perform secondary clean The side clinching work is performed on the parts through the operation of the clutching device 33.

On the other hand, after completion of the secondary clinching operation for joining the side portions of the parts, the respective secondary clinching devices 33 are returned to their initial positions by the reverse order of the operation of each cylinder.

13 to 15 show the structure of the component transfer unit in the automated frame for manufacturing an LCD frame according to the present invention.

As shown in FIGS. 13 to 15, a plurality of holders 41, for example, three holders 41, for transferring components between processes may be provided on the upper portion of the frame structure 100. , The first clinching portion 20, the second clinching portion 30 and the product discharge portion 50 are arranged side by side in a row, each holder 41 is reciprocated along the X-axis direction for each process The task is to move the parts that are present to the next process.

The holder 41 has a rectangular frame structure, and a suction pad 47 is mounted on the bottom of each corner of the rectangular frame, so that the component can be picked up and lifted by the suction force exerted therefrom.
