Description

Auto insert apparatus for wire

The present invention relates to an automatic wire inserting machine, and more particularly, to a device for automatically inserting a wire used in assembly between a chassis side and a cover side in a display device such as a large TV.

With the recent development of technology, the proportion of display devices has shifted from the CRT method to flat panel display devices such as LCD, PDP, and OLED, and the thickness of the display device is becoming considerably thinner, and even in the case of a large-screen TV, it is thicker than conventional TVs. is being manufactured in a thin and ultra-thin form.

For example, a display device used for a flat-panel TV has an increasingly larger screen, and the thickness of the TV is getting thinner due to the spread of wall-mounted TVs.

Current display devices used in flat panel TVs include plasma display devices (PDP), liquid crystal displays (LCDs), light emitting diodes (LEDs), and organic light emitting diodes (OLEDs). There are display devices using 'OLED'.

Here, the LCD is a device that displays information by using the electrical and optical properties of the liquid crystal material injected into the liquid crystal display panel, and in recent years, various information devices such as TVs, computer monitors, portable video cameras, digital cameras, etc. It is most widely used in communication devices.

Such a display device receives an image signal from an information processing device, converts it into a signal for liquid crystal control, and adjusts the amount of light transmitted through the liquid crystal so that the image signal in an electrical form can be visually recognized.

That is, the display device transmits light shining from the back through the liquid crystal composed of a liquid element, and has an advantage that the screen is clear and clear, but has a disadvantage that the eyes are easily tired and the sharpness changes greatly depending on the position.

In addition, since the display device is a so-called light-receiving display that cannot emit light by itself, it includes a separate light source, that is, a backlight unit.

The components of the display device are housed inside the chassis for protection from external impact, and this chassis is composed of a bottom chassis accommodating a backlight unit and a top chassis accommodating a liquid crystal display panel. do.

Here, the top chassis is mainly made of a metal material such as aluminum alloy or stainless steel to protect the liquid crystal panel and prevent the backlight unit components from being separated, and the bottom chassis is mainly made of EG (Electronic Galvanizing) material. It is manufactured and serves to protect the entire rear surface of the liquid crystal panel and backlight unit.

In addition, a cover is provided on the rear surface of the bottom chassis to protect and fix internal components from external impacts and prevent them from being separated to the outside. In this case, the cover is the edge of the bottom chassis using a hook on the inside surface. It is assembled into a structure in which it is caught and fixed by a wire inserted along it, a structure in which it is coupled through a double-sided tape, and a structure in which it is fastened through a screw.

On the other hand, in the case of the wire used for assembling the cover, it is mounted in a structure that is inserted into a hole or groove on the chassis side. Conventionally, after the chassis is formed, the chassis is taken out from the process line, and then the operator uses a separate tool or jig. Since it is a method of manually press-fitting and mounting the wire on the chassis by using it, there are disadvantages in productivity such as deterioration of workability, difficulty in securing work quality, and lengthy process cycle time.

To this end, the wire insert unit 16 includes a wire winder 12 as a means for unwinding the wound wire.

The wire winder 12 serves to supply the wire provided to the chassis, and is formed in the form of winding the wire on a drum.

The wire winder 12 is positioned in a line on the back of the wire alignment 13 to be described later and is freely rotatable on the winder plate 54 of the slider (not shown) side bracket assembly 52 of the XYZ robot. is installed with

Accordingly, when a pulling force is generated on the wire by the operation of the wire feeder 14 to be described later, the wire wound around the wire winder 12 can be unwound by itself.

In addition, the wire insert unit 16 is arranged side by side in front of the wire winder 12 and is a means for performing an alignment operation such as straightening the wire released from the wire winder 12. The wire alignment 13 ) is included.

To this end, a vertical alignment plate 17 is installed on the slider-side bracket assembly 52 of the XYZ robot, and on the front surface of the alignment plate 17 installed in this way, the wires are arranged in a line along the trajectory on the horizontal line. A plurality of upper idlers 18 and a plurality of lower idlers 19 for contacting and supporting the lower side of the wire are installed.

Here, the upper idler 18 and the lower idler 19 are in the form of rolls having an axis, and can be installed in a structure supported by a shaft in a horizontal posture through a bearing on the alignment plate 14 side. The upper and lower idlers 18 and 19 can be freely rotated around the axis together with the axis.

And, a wire groove 47a is formed along the middle of the width on the outer peripheral surface of the lower idler 19, that is, the circumferential surface where the wire is in contact, so that the wire is inserted into the wire groove 47a of the lower idler 19 when the wire proceeds. It is possible to proceed in a partially accommodated state, and accordingly, the wire is guided along the wire groove 47a of the lower idler 19, so that the wire can proceed in a straight line without departing from the path to the left and right.

In addition, the upper idler 18 is installed to be movable in the vertical direction, so that it can be installed in a structure that can widen the gap with the lower idler 19 when the wire is abnormal as well as when the wire is installed.

For example, a vertical long hole 49a is formed in the alignment plate 17, and an idler bracket 50a having a shorter length than the long hole while taking the same shape as the long hole is mounted inside the long hole 49a. , the shaft of the upper idler 18 to the idler bracket 50a mounted in this way can be installed via a bearing.

Here, in the case of the idler bracket (50a), it is possible to move up and down using the play in the long hole (49a), and is pushed down by the set screw (51a) fastened to the alignment plate (17) in a normal use state. It is possible to maintain the position while idling, and eventually, the upper idler 18 at this time can support the wire while contacting and pressing the wire together with the lower idler 19 with the wire interposed therebetween.

Accordingly, after loosening the set screw 51a that fixes the position of the idler bracket 50a, the idler bracket 50a and the upper idler 18 are raised upward through the play in the long hole 49a, Since the gap with the lower idler 19 can be secured, it is possible to mount the wire in this state or to remove the wire when the wire is abnormal.

A plurality of left idlers 21 and a plurality of right idlers 22 for contacting and supporting the right side of the wire are installed.

Here, the left idler 21 and the right idler 22 are in the form of rolls having an axis, and can be installed on the feeder plate 20 side with a bearing as a medium to be installed in a structure supported by an axis of a vertical posture. The left and right idlers 21 and 22 can be freely rotated around the axis together with the axis.

In addition, a wire groove 47b is formed along the middle of the width on the outer peripheral surface of the right idler 22, that is, on the circumferential surface where the wire is in contact, so that the wire is in the wire groove 47b of the right idler 22 when the wire proceeds. It is possible to proceed in a partially accommodated state, and accordingly, the wire is guided along the wire groove 47b of the right idler 22, so that the wire can proceed in a straight line without deviation from the path up and down.

In addition, the left idler 21 is installed to be movable in the left and right directions, so that it can be installed in a structure that can widen the gap with the right idler 22 when the wire is abnormal as well as when the wire is installed.

For example, a horizontal long hole 49b is formed in the feeder plate 20, and an idler bracket 50b having a shorter length than the long hole while taking the same shape as the long hole is mounted inside the long hole 49b. , the shaft of the left idler 21 to the idler bracket 50b mounted in this way can be installed via a bearing.

Here, in the case of the idler bracket (50b), it is possible to move left and right using the play in the long hole (49b), and in a normal use state, it is pushed to the right by the set screw (51b) fastened to the feeder plate (20). It is possible to maintain the position while idling, and eventually the left idler 21 at this time can support the wire while contacting and pressing the wire together with the right idler 22 with the wire interposed therebetween.

Accordingly, after loosening the set screw 51b that fixes the position of the idler bracket 50b, the idler bracket 50b and the left idler 21 are pushed to the left through the play in the long hole 49b. Since the gap with the right idler 22 can be secured, the wire can be mounted in this state or the wire can be removed when the wire is abnormal.

Of course, after the wire is mounted, the idler bracket 50 and the upper idler 18 are lowered, and then the set screw 51a is fastened again to fix the upper idler 18 so that the upper idler 18 can be positioned normally.

In particular, the plurality of left idlers 21 and right idlers 22 may be arranged such that their axes are positioned on the same horizontal line while pairing to match one by one left and right, and at least one of the left idlers 21 is front and rear It can be arranged so that its axis is positioned on a horizontal line passing between the two right idlers 22 arranged in the direction (based on the wire traveling direction).

In addition to being installed, the shaft of the driving motor 23 at this time is connected to the shaft of any one of the right idlers 22 via a coupler.

For example, the axis of the driving motor 23 is the axis of the right idler 22 located at the front of the plurality of right idlers 22 arranged in a line along the wire traveling direction based on the wire traveling direction. Connected.

Accordingly, when the driving motor 23 is operated, the right idler 22 and the left idler 21 rotate together to pull the wire sandwiched therebetween, so that the wire can be transferred to the front.

In addition, the wire insert unit 16 is disposed at the front end of the wire feeder 14 and includes a wire cutter 15 as a means for cutting the wire after the wire insertion is completed on the chassis side.

To this end, the slider side bracket assembly 52 of the XYZ robot is provided with a cutter plate 24 that extends forward and takes a vertical posture, and on one side of the cutter plate 24 installed in this way, a pin 30 is attached. The cutter block 27 that is fixed by the angle adjustment is possible.

In addition, the wire insert unit 16 includes a guide block 35 as a means for guiding the progress of the wire sent from the wire feeder 14 to the wire cutter 15 .

The guide block 35 is installed at the front end of the feeder plate 20 of the wire feeder 14, and a guide hole 33 through which the wire can pass is formed at the rear end of the guide block 35 installed in this way. At the same time, a straight guide groove 34 placed on the same line as the guide hole 33 is formed on the upper surface of the guide block 35 .

Accordingly, the wire passing through the wire feeder 14 is guided along the guide hole 33 and the guide groove 34 of the guide block 35 on the wire cutter 15 side, that is, of the tongs-type cutter 28 . It is possible to enter between the fixed blade 25 and the movable blade 26 .

On the other hand, the lower jig unit 11 includes a wire bender 32 as a means for bending the wire by pressing the end of the wire immediately after cutting the wire by the tongs-type cutter 28 .

The up-down plate 38 is arranged in parallel with one side of the bending cylinder 37 installed in this way, and the lower end of the up-down plate 38 arranged in this way is connected to the rod side of the bending cylinder 37 .

Accordingly, the up-down plate 37 can also be raised and lowered during the forward/backward operation of the bending cylinder 37 .

Here, at the upper end of the up-down plate 37, a bending machine accommodating groove 46 in the form of a substantially "V" shape is formed downward from the center of the width. At this time, the bending machine accommodating groove 46 has a bending machine 53 to be described later. ) can be positioned, and at the same time both inclined walls of the bending machine receiving groove 46 come into contact with the handle of the banding machine 53 and close the handle, and eventually the up-down plate 37 rises and During the lowering operation, the banding machine 53 can be operated while the handle portion in the bending machine receiving groove 46 is interlocked.

It is composed of a pair of handles 57 which are disposed in opposite directions to each other while passing through the central axis 58 .

At this time, a spring is interposed between the pair of handles, and as long as an external force does not act, the pair of handles 57 can always maintain an open state by the spring force.

In particular, the female bending blade 55 is formed in the form of a concave asymmetric semi-circular groove, while the male bending blade 56 is formed in the form of a convex, asymmetric semi-circular protrusion. As the protrusions of the male bending blade 56 are shaped, the wire therebetween can be bent into a “Z” shape or an “S” shape.

Therefore, when the end of the wire is cut by the operation of the tongs-type cutter 28, the bending cylinder 37 is continuously operated upward (reversed rod), and the up-down plate connected to the rod of the bending cylinder 37 ( 38) will rise.

Next, when the up-down plate 38 rises, the handle 57 of the banding machine 53 that is spread out in the bending machine receiving groove 46 of the up-down plate 38 becomes narrower as it goes down. 46), and at the same time, the female bending blade 55 and the male bending blade 56 of the bending machine 53 are also retracted to bend the wire therebetween.

On the other hand, the upper and lower jig units 10 and 11 and the wire insert unit 16 are disposed in one area on the automated process line L for performing each press forming process for the chassis, and are connected to the chassis press forming process. The insertion process can be made.

Accordingly, the chassis (not shown) that has completed the predetermined press forming process in the previous process is transferred along the X-axis direction through shuttle transfer, etc., placed on the turntable (not shown), and then the turntable is moved in the Y-axis direction ( When the chassis is loaded into the correct position through the forward) and Z-axis movement (raise), the upper jig unit 10 and the lower jig unit 11 are lowered and raised to clamp the chassis, along with the wire insert unit ( 16) Also, after moving in the XYZ axis direction to fix the position, wire inserting work is performed on the chassis, and the chassis, which has completed the wire inserting process continuously, moves the turntable in the Z axis direction (downward) and the Y axis direction movement ( In addition to being positioned on the X-axis line line through backward), it can be transferred to a later process by shuttle transfer or the like at this position.

In this way, the upper and lower jig units 10 and 11 and the wire insert unit 16 are arranged in one continuous area among the entire area on the automated process line L for performing the panel press forming process, and the press forming process and the wire insert By allowing the process to be performed in a linkage, it is possible to improve the efficiency of the process when building an automated system for the overall panel press forming process including the wire insert process.

8A to 8C are schematic front views illustrating an operating state of an automatic wire inserter according to an embodiment of the present invention.

As shown in FIGS. 8A to 8C , the turntable, which has been handed over the chassis 100 that has completed the predetermined press forming process in the previous process, moves in the Y-axis direction (forward) and moves in the Z-axis direction (rises). The chassis 100 is loaded in place.

Next, by the lowering operation of the upper jig unit 10 and the raising operation of the lower jig unit 11 , the chassis 100 is a unit of the upper jig block 40 and the unit of the lower jig block 41a and the lower jig block 36 . It is clamped by a jig block 41b.

At the same time, the wire insert unit 16 is moved in the X-Y-Z axis direction to take the correct position.

That is, the wire insert unit 16 is positioned on a line parallel to the groove (not shown) of the chassis 100 .

Next, the wire 110 released from the wire winder 14 by the operation of the wire feeder 14 passes through the wire alignment 13, the wire feeder 14, and the wire cutter 15 in sequence while the chassis 100. inserted into the groove of

Of course, in the case of the wire 110, the insertion process can be made in a state in which the wire is extended from the wire winder 14 to the wire cutter 15 side by the operator in advance before the first operation.

Next, after the wire 110 of a certain length is inserted, the tong-type cutter 28 of the wire cutter 15 operates to cut the wire 110, and continues by the cutting operation of the wire bender 32 The end of the wire 110, that is, the cut end of the wire 110 protruding out of the groove of the chassis 100 is pressed and bent into a “Z” shape or an “S” shape and is in close contact with the chassis 100 side.

Such a wire insertion process can be performed simultaneously in four wire insert units 16 .

When the insertion process of the wire 110 for one chassis 100 is completed in this way, each unit, that is, the upper and lower jig units 10 and 11 and the wire insert unit 16 is returned to its initial position, and continues After the wire insert process, the chassis 100 is positioned on the X-axis line through the Z-axis movement (downward) and Y-axis movement (reverse) of the turntable, and at this position, it is transferred to the post-process by shuttle transfer, etc. can be transported.

As described above, in the present invention, during the process of inserting and mounting the wire in the chassis of the display device, the entire process such as the wire supply process, the wire feeding process, the wire cutting process, and the wire insert process is performed as an automated process, and the press forming process and wire insertion process By establishing a new system linked to the process, it is possible to improve workability and secure product quality, reduce process cycle time and improve overall productivity related to the chassis forming process.
