Such a liquid crystal display panel assembly is stored and protected in a chassis, and the chassis is usually made of aluminum alloy, stainless steel (SUS), SECC, SGLCC, or other metal material.

On the other hand, the chassis is subjected to several press forming processes, for example, blanking for outer shape machining → piercing for hole machining → lancing/forming for hook machining → box for outer bending machining. It is manufactured through the process of box-bending → opening for bezel processing → chamfer for deburring of the bezel part. It is packaged and shipped as a product after going through the process of attaching it.

However, in the prior art, since the worker manually attaches the insulation to the chassis, there is a disadvantage that not only the workability or productivity is lowered but also the labor cost is increased. There is a problem in that the accuracy of the work, for example, the accuracy of the attachment state or attachment position, etc. is greatly reduced, and the reliability of the quality of the product is lowered, such as a lot of defects such as the introduction of air bubbles during the attachment process.

The base plate 10 is mounted and supported on the LM guide 11 installed in this way, so that it is possible to linearly move in the X-axis direction.

That is, the horizontal plate body 10a of the base plate 10 is mounted and fixed on the two sliders in the LM guide 11 in the first row and one slider in the LM guide 11 in the other row. When the drive unit 17 is driven, the base plate 10 can be moved along the X-axis direction while being guided by the LM guide 11 .

Here, both ends of the timing belt 17a of the drive unit 17 are respectively connected to the horizontal plate body 10a of the base plate 10, so that the base plate 10 at this time moves in the direction in which the timing belt 17a moves. Correspondingly, it is possible to move in the forward direction or in the reverse direction along the X-axis direction.

In addition, the insulation attach device includes an unwinder 12 as a means for supplying an insulation tape (hereinafter, referred to as a tape).

The unwinder 12 is a type of winder on which a tape is wound, and is installed in a freely rotatable structure while being penetrated and supported by the vertical plate body 10b of the base plate 10 using the unwinder shaft 22 on the rear side. do.

The unwinder 12 installed in this way can unwind the tape while freely rotating by the pulling force in the process of attaching the tape.

That is, when the tape is attached, the unwinder 12 can also be rotated naturally as the tape is pulled and released.

And, the unwinder 12 is provided with a clutch assembly 12b as a means for regulating the rotation of the unwinder shaft 22, and the clutch assembly 12b at this time is installed on the rear surface of the vertical plate body 10b. It is supported on the clutch bracket 12c, which is connected to the unwinder shaft 22, and controls the rotation speed of the unwinder shaft 22 and prevents reverse rotation.

Accordingly, the unwinder 12 is rotated at an appropriate speed under rotation regulation by the clutch assembly 12c so that the tape can be smoothly unwound.

Here, as the clutch assembly, a known clutch assembly applied to an unwinder or a rewinder may be applied, and a detailed description thereof will be omitted.

In addition, the insulation attach device includes a plurality of guide rollers 13 as a means for guiding the moving trajectory of the tape.

The guide roller 13 serves to provide an appropriate tension while guiding the tape progress trajectory until the tape released from the unwinder 12 reaches the tape setting unit 15 to be described later.

To this end, the plurality of guide rollers 13 are arranged while maintaining the vertical height difference along the lower end of the vertical plate body 10b in the base plate 10, and each guide roller 13 arranged in this way has a bearing (not shown). City) is installed in a freely rotatable structure on the vertical plate body (10b) through the medium.

In the present invention, an example is shown in which four guide rollers 13 having different heights are applied in an up and down zigzag form.

In particular, at least one guide roller 13 among the plurality of guide rollers 13 is elastically supported by a spring 18 and is installed in a structure capable of vertical movement along the long hole 20 while providing tension to the tape. will do

For example, a spring bracket 19 is installed on the vertical plate body 10b of the base plate 10, and a vertical spring 18 is installed between the spring bracket 19 side and the guide roller 13 side. ) is connected and installed.

Accordingly, the guide roller 13 receives the elasticity of the spring 18 and always receives a force to ascend upward, and eventually, the tape spanning over the rolling surface of the guide roller 13 can also be pulled upward.

That is, the tape is draped over the rolling surface of the guide roller 13 receiving the elastic support of the spring 18, and the rolling of each guide roller 13 disposed before and after at a lower position than the guide roller 13 As the surface is stretched downward, the tape is also pulled upward by the upward force of the guide roller 13 receiving the elastic support of the spring 18, and consequently, an appropriate tension can be maintained on the tape.

Here, the elasticity of the spring 18 can be set to an appropriate level in consideration of the tension acting on the tape.

Accordingly, the tape unwinding from the unwinder 12 passes through the respective guide rollers 13 up and down and can proceed toward the tape setting unit 15 with tension.

In addition, the insulation attach device includes a tape setting unit 15 as a means for positioning the end of the tape up to the attachment point of the chassis bottom and continuously pressing the end of the tape to attach it.

The tape setting unit 15 uses the ascending and descending operations in the inclined direction of the slope cylinder 14 installed on the vertical plate body 10b of the base plate 10 before attaching the tape to the chassis in earnest. It serves to attach the end part to the chassis.

To this end, a slope cylinder 14 of an inclined posture with the rod upward is installed on the front surface of the vertical plate body 10b of the base plate 10, and the rod of the slope cylinder 14 installed in this way has a vertical member and horizontal A rod bracket 21a in the shape of a "L" made of a member is installed, and a moving plate 15c in the form of a vertical plate is installed on the front side of the vertical member of the rod bracket 21a at this time in an inclined posture.

In addition, at the upper end of the moving plate 15c, a bar-shaped guide plate 15a is installed side by side in an inclined posture, and the rear end of the guide plate 15a at this time is the upper surface of the horizontal member of the rod bracket 21a. is also fixed on

Here, the guide plate 15a serves to guide the tape while supporting the tape.

And, on the front surface of the moving plate 15c, a plurality of idlers 15b, for example, three idlers 15b forming an inverted triangle arrangement structure are installed in a freely rotatable structure.

At this time, the front and rear two idlers 15b disposed upward among the three idlers 15b may have their rolling surfaces partially protrude through a cutout (not shown) formed along the middle of the width of the guide plate 15a. there will be

Accordingly, the tape, which has entered the tape setting unit 15 side after passing through the plurality of guide rollers 13, proceeds along the upper surface of the guide plate 15a, and continues down while passing through the three idlers 15b. It can be sent to the clamping bar (15d) side to be described later after proceeding by bending the direction once to the top and once to the top.

Accordingly, during the forward operation of the slope cylinder 14, the entire moving plate 15a including the guide plate 15a and the idler 15b can be raised upward along the inclined direction.

The tape setting unit 15 includes a clamping bar 15d and a clamping cylinder 15e, which serve to lift the moving plate 15a together with the tape.

To this end, the clamping cylinder 15e is installed in an inclined posture with the rod facing up on the front surface of the moving plate 15a, and the incision portion of the guide plate 15a is perpendicular to the rod of the clamping cylinder 15e installed in this way. A rod bracket 21b composed of two vertical walls that penetrates and is disposed in the width direction of the guide plate 15a and maintains a relatively wide interval compared to the width of the tape is installed, and at this time, a wedge is provided at the upper end of the rod bracket 21b. A clamping bar 15d having a mold pressing portion is installed in a horizontal posture.

Accordingly, when the moving plate 15a rises to attach the end of the tape at the beginning of the tape attachment process, the clamping bar 15d comes down by the lowering operation of the clamping cylinder 15e and presses the upper surface of the tape to press the guide plate ( It is possible to hold the tape on 14a), and while the tape attaching process is being performed, the clamping bar 15d is raised by the lifting operation of the clamping cylinder 15e and does not interfere with the progress of the tape.

In addition, the tape setting unit 15 includes an attach roller 15f and an attach cylinder 15g serving to attach the tape end portion to the chassis bottom.

The attach cylinder (15g) is installed in a vertical posture on the front surface of the moving plate (15c), and a rod bracket (21c) is installed on the rod of the attach cylinder (15g) installed in this way, at this time the rod bracket (21c) On the attachment roller (15f) is installed in a freely rotatable structure.

Accordingly, when the attach cylinder 15g is lifted from the rising position of the moving plate 15c, the tape end is attached to the chassis bottom by the attach roller 15f.

That is, the end of the tape is placed on the upper surface of the rolling surface of the attach roller 15f in a state where the tape is drooping down, and in this state, the attach holer 15f rises and presses the tape on the bottom of the chassis. The end can be attached to the chassis underside.

In addition, the insulation attach device includes a tape attach unit 16 as a means for attaching the tape along the bottom of the chassis.

That is, the tape attach unit 16 is installed on the vertical plate body 10b of the base plate 10 and moves together when the base plate moves while moving along the upper and lower surfaces of the chassis. It serves to attach the tape over the entire length of the chassis (actually the entire length excluding some lengths of the front end and rear end of the chassis in the longitudinal direction).

To this end, as shown in Figs. 1 to 7, the vertical plate body 10b of the base plate 10 has a vertical posture that serves to raise and lower the upper and lower rollers 16a and 16b to be described later. An up-down cylinder 16c is installed.

Here, the up-down cylinder 16c can be installed on the front side of the vertical plate body 10b directly through the cylinder body or through a separate bracket.

A guide block 16e composed of a combination of a horizontal plate and a vertical plate is installed on the rod of the up-down cylinder 16c, and at this time, the guide block 16e has one side on the vertical plate and is horizontally cut long. A slot 16d of the form is formed.

At this time, the guide block 16e can enter the side end of the chassis through the slot 16d.

And, on the front surface of the guide block 16e, an upper roller 16a and a lower roller 16b in a horizontal posture are installed in parallel up and down, and the upper roller 16a and the lower roller 16b installed in this way are It rides on the upper and lower surfaces of the chassis and serves as a guide and attaching tapes during the process.

That is, the upper roller 16a comes into contact with the upper surface of the chassis and rolls to guide the tape attachment process, and the lower roller 16b comes into contact with the bottom surface of the chassis with the tape interposed therebetween and rolls the tape while rolling. It serves to attach to the bottom of the chassis.

Here, in the case of the upper roller 16a, the upper roller 16a is installed in a vertically movable structure and is always supported elastically downward by the roller spring 16i. Accordingly, the upper roller 16a can be in contact with the chassis upper surface while pressing On the other hand, the slot 16d formed in the guide block 16e can maintain a height parallel to the contact surface between the upper roller 16a and the lower roller 16b.

Accordingly, when the chassis passes the position of the tape attach unit 16 and is loaded into the tape attachment region, the entire guide block 16e including the upper and lower rollers 16a and 16b is moved by the upward operation of the up-down cylinder 16c. The height of the contact surface and the slot 16d between the upper and lower rollers 16a and 16b at this time along with the elevated position is the same as the height of the chassis, and the chassis is moved forward together by the forward movement of the base plate 10 in a certain section. While entering the side, the upper and lower rollers 16a and 16b come into contact with the upper and lower surfaces of the chassis.

Subsequently, after attaching the end of the tape by the operation of the tape setting unit 15, the entire guide block 16e including the upper and lower rollers 16a and 16b is also moved forward together by the forward movement of the base plate 10. The tape attachment operation can be made by pressing the lower roller 16d.

In particular, the tape attach unit 16 includes a cutting scissors 16g that serves to cut the tape end after the tape attachment is completed.

The cutting scissors 16g serve to cut the end of the tape after the tape is attached while performing a forward and backward position movement and cutting operation.

To this end, on the front surface of the cylinder body of the up-down cylinder 16c, a plate for supporting scissors 16j in an approximately "L" shape is installed in a horizontal position, and the Y-axis Scissors driving cylinders 16f arranged side by side along the direction are installed, and on the side of the slider 16l of the scissors driving cylinder 16f, the body portion of the cutting scissors 16g, that is, the cutting scissors 16g. An actuator bracket (16m) is installed to support the actuator body part that operates the .

That is, the entire actuator including the cutting scissors (16g) is installed in a structure supported on the actuator bracket (16m).

Accordingly, after the tape attachment is completed, when the scissors driving cylinder 16f is operated forward, the cutting scissors 16g is placed at the end of the tape, that is, at the imaginary end adjacent to the portion attached to the chassis side with the two blades spread apart. At the same time, the tape is cut while both blades of the cutting scissors 16g are operated by the actuator operation, and the cutting scissors 16g are moved to the initial position by the backward operation of the scissors driving cylinder 16f. By returning, the tape cutting operation can be completed.

Here, the actuator for operating the cutting scissors (16g) is a known air tool type actuator, and a detailed operation description thereof will be omitted.

In addition, a heater 16h is provided in the tape attach unit 16, and the heater 16h at this time serves to apply heat or hot air to the area where the tape is attached.

To this end, the actuator bracket 16m is provided with an actuator auxiliary bracket 16n in the form of a bar in a horizontal posture, and a heater 16h is installed at the front end of the actuator auxiliary bracket 16n installed in this way.

Here, as the heater 16h, a known heater such as an electric heater may be applied.

Accordingly, when the tape is attached by the upper and lower rollers 16a and 16b of the tape attach unit 16, the heater is positioned ahead of this in the moving direction of the upper and lower rollers 16a and 16b and is located close to the tape attachment site. After preheating the tape to be attached (16h), the tape is attached by compression of the upper and lower rollers 16a and 16b, so that the tape can be attached more closely.

In addition, the insulation attach device uses the power of the motor 17b for driving the timing belt 17a connected to the horizontal plate body 10a of the base plate 10 to move the entire base plate 10 in a straight line. It includes a drive unit (17).

This drive unit 17 uses the driving force of the servo-type motor 17b and the electric action of the timing belt 17a to the base plate 10 to which the tape setting unit 15 and the tape attach unit 16 belong. It plays a role of moving in the X-axis direction, and in the process of moving in this way, the tape attachment operation can be made.

To this end, a motor 17b is installed in the base frame 100, and a pulley shaft 17e is connected to the shaft of the motor 17b via a coupling. At the same time, the pulley shaft 17e is connected to the base frame ( 100), and the driven pulley 17c is installed on the pulley shaft 17e installed in this way, and the driven pulley is on the base frame 100 opposite to the driving pulley 17c. (17d) is installed.

In this case, the motor 17b is a servo motor capable of forward and reverse rotation, and can be controlled by output control by a controller (not shown) to control continuous operation, intermittent operation, forward and reverse rotation operation, and the like.

In addition, a timing belt 17a capable of maintaining a closed curve shape while being arranged in parallel along the X-axis direction is connected between the driving pulley 17c and the driven pulley 17d.

Here, the timing belt 17a is in a form in which one side is broken, and at this time, the broken one side is fixed to one side of the horizontal plate body 10a of the base plate 10 , and the other broken side is the horizontal plate body 10a of the base plate 10 . ) As it is fixed to the other side, the base plate 10 is also movable by the movement of the timing belt 17a.

Accordingly, when the motor 17b is driven, the timing belt 17a spanned between the drive pulleys 17c and the driven pulley 17d on both sides operates in the forward or reverse direction, and eventually the timing belt 17a The base plate 10 connected to ) can also be moved forward or returned backward.

On the other hand, the insulation attach device including the tape setting unit 15, the tape attach unit 16, the drive unit 17, etc. is an automated process line for performing each press forming process for the chassis, for example, It can be arranged in one region on a line continuously continuous in the X-axis direction to which the attach process region belongs.

Accordingly, when the chassis (not shown) that has completed the predetermined press forming process in the previous process is positioned in the attach process area through shuttle transfer or conveyor transfer, the tape setting unit 15, the tape attach unit ( 16), the tape attach process to the chassis is performed by the operation of the drive unit 17, etc., and the chassis after the tape attach process is continuously discharged from the attach process area by shuttle transfer or conveyor transfer. , it can be transferred to a later process.

In this way, the insulation attach device is disposed in one continuous area among the entire area on the automated process line for performing the chassis press forming process, so that the press forming process and the tape attach process can be performed in a linkage, so that the tape attach It is possible to improve the efficiency of the process when building an automation system for the entire chassis press forming process including the process.

Next, when the motor 17b of the drive unit 17 operates in the forward direction, the entire base plate 10 moves forward for a certain section in the X-axis direction, and between the upper and lower rollers 16a and 16b and the guide block. The chassis relatively enters into the slot 16d of (16e), and the motor 17b stops, and at this time, the upper and lower rollers 16a and 16b are respectively provided on the upper and lower surfaces of the chassis 120. clings to

Next, when the slope cylinder 14 of the tape setting unit 15 is operated upward, the entire moving plate 15c including the attach roller 15f and the attach cylinder 15g rises obliquely to the chassis ( It is positioned close enough to almost touch the bottom surface of the 120), and the insulation tape 130 is also pulled together and rises, and the insulation tape 130 as much as the tape pulled out from the unwinder 12 is released.

Here, when the insulation tape 130 is pulled together by the rising of the moving plate 15c and ascends, the portion immediately behind the end of the insulation tape 130 is a clamping bar ( It is in a fixed state by being pressed by the lowering action of 15d).

Subsequently, the clamping bar 15d is spaced apart from the insulation tape 130 by the lifting operation of the clamping cylinder 15e, and the attach roller 15f is raised by the lifting operation of the attach cylinder 16g. The end of the insulation tape 130 placed on it is pressed to the bottom of the chassis 120 to be attached thereto.

Next, when the end of the insulation tape 130 is attached to the lower surface of the chassis 120, the attach cylinder 15g is lowered and returned while the slope cylinder 14 is also lowered and the entire tape setting unit 15 is lowered. is returned to the initial position before ascent.

At the same time, when the motor 17b of the drive unit 17 operates in the forward direction again, the entire base plate 10 moves forward along the X-axis direction, and the edge portion of the chassis 130 during this movement. The insulation tape 130 is attached to the bottom surface of the chassis 120 by the upper roller 16a and the lower roller 16b traveling along the upper surface and the lower surface, and substantially by the lower roller 16b.

Here, between the time when the entire tape setting unit 15 is returned to its initial position before rising and the time when the upper and lower rollers 16a and 16b start to attach the insulation tape 130 by the forward movement of the base plate 10 . Since there is a slight time difference, the insulation tape 130 may be slightly stretched, but immediately the upper and lower rollers 16a and 16b move forward and attach the insulation tape 130, so that the insulation tape 130 is taut again. It can be attached to the chassis side while being pulled to the chassis.

Of course, when the insulation tape 130 is attached at this time, the attachment portion of the insulation tape 130 is heated by the operation of the heater 16h, so that the insulation tape 130 can be attached more effectively, and the unwinder From (12), the insulation tape 130 can be continuously released.

Next, when the attaching operation of the insulation tape 130 to the entire length section (set length section) of the chassis 120 is completed, the motor 17b stops, and the scissor driving cylinder 16f continues to advance. In addition to the operation, by the operation of the actuator, the cutting scissors (16g) cut the insulation tape 130 in between, and the end of the cut insulation tape 130 at this time is drooping down. It is placed on the upper surface of the attach roller (15f).

Subsequently, when the motor 17b of the drive unit 17 operates again in the forward direction, the entire base plate 10 moves more forward along the X-axis direction, and the motor 17b is moved away from the tip of the chassis 120 . When the up-down cylinder 16c of the tape attach unit 16 is lowered at the same time as the operation of 17b is stopped, the upper and lower rollers 16a and 16b and the guide block 16e are lowered while the chassis 130 is moved. located at the bottom

In this state, when the motor 17b of the drive unit 17 operates in the reverse direction, the entire base plate 10 moves backward in the X-axis direction and returns to its initial position, so that one chassis 120 The process of attaching the insulation tape 130 to the air conditioner is completed.
