The split split for separate use of Patent Document 1 is a knocking method using a bar or a roll. The bending division of Patent Document 2 is a cutting method using a roll as a bending division member. The bending division of Patent Document 3 is a breaking method using a broken bar.

When the above-described bending division method is applied to the bending division of the recent panel, various problems occur. In other words, the recent liquid crystal panel is very precise (because the laminated substrate or the electrode film is made as thin as possible to achieve weight reduction or cost reduction), and therefore, the crack propagates to the bending division with the breakage. The other part is the cause of the occurrence of the secondary product. In addition, since the internal wiring is relatively fine, the wire is broken in addition to the impact due to the knocking, and the secondary product is accompanied by the separation. The debris is scattered and the removal of the attached debris is required.

In particular, the terminal for exposing the electrode from the edge of the panel is exposed by the bending division, but at this time, if the split panel or the terminal is exposed, the end of the unnecessary material (waste material) is exposed. When the material slides down in contact with the exposed terminal surface, the terminal surface is damaged (broken) and the secondary product is formed.

In addition, when the edge (cutting edge) of the liquid crystal panel is bent and divided (separated), if the above-described breaking method is employed, the crack is spread to a portion other than the bending division with the breaking. The cause of the secondary product is generated, and the problem of disconnection is caused by the impact of the knocking.

Therefore, the present invention provides a bending and dividing device for a liquid crystal panel that solves the above problems.

In order to solve the above problems, the present invention adopts a configuration including a belt conveyor that is disposed to convey a liquid crystal panel, and a bending split rod that is disposed in a manner of being lifted by a lifting mechanism. The upper side of the carrying side of the belt conveyor is bent at a position of the upper side; the suction nozzle is disposed outside the bending split rod to attract the generated debris; the splitting of the pallet is performed, and the opposite end can be The two mobile stations are rotatably supported and the opposite ends are respectively raised and lowered by the lifting mechanism, and the two moving stages are disposed below the bending split rod, and are disposed on the belt conveyor. The lower side of the belt is moved forward and backward by the moving mechanism; the cutter is arranged to be raised by the lifting mechanism as the moving body and the cutting line is cut on the lower surface of the liquid crystal panel, and the moving body is disposed in the belt The front side of the head of the conveyor moves in the width direction of the lower surface of the liquid crystal panel by a reciprocating mechanism; the backup lever is disposed such that the lifting line is directly above the scribe line drawn by the cutter The backup lever is lowered to press the upper surface of the liquid crystal panel; the swinging table is disposed in front of the cutter, so that the liquid crystal panel is transferred to the swinging table and received by the swinging table a lifting mechanism configured to swing the swinging table in an up-and-down direction; and a guiding mechanism provided on the side of the spare lever on a lower side of the swinging table, having an ascending guiding portion configured to be accompanied by The swinging of the swinging table caused by the front and rear lifting mechanisms in the downward direction causes the swinging table to slide forward.

Further, a configuration is adopted in which the guiding mechanism is formed by a combination of a rising guiding portion and a descending guiding portion, and the descending guiding portion is connected to the rising guiding portion and extends downward so as to be accompanied by the swinging by the lifting mechanism The table swings in the ascending direction to slide the swing table forward.

Further, a configuration is adopted in which the first receiving mechanism and the second receiving mechanism are provided before and after receiving and supplying the liquid crystal panel, and the supporting member is provided between the first receiving mechanism and the second receiving mechanism. a side of the swinging body that is rotatably supported by the opposite ends of the two supporting members via the support shaft in a freely rotatable manner; the base is disposed on the upper end side of the two swinging bodies, using the guide rail and The slider that is engaged with the guide rail slides in the front-rear direction; the advancing and retracting mechanism allows the base to slide in the front-rear direction to change the position; the claw is grasped so that the sliders on both sides can be freely Slidingly engaging with the longitudinal rails, the longitudinal rails are disposed on the lower end side of the swinging body and the base; the lifting mechanism is arranged to lift the two gripping claws; and the swinging mechanism is arranged The swinging body is caused to swing in the front-rear direction.

Further, a configuration is adopted in which the first receiving mechanism and the second receiving mechanism are provided before and after receiving and supplying the liquid crystal panel, and the supporting member is provided between the first receiving mechanism and the second receiving mechanism. The upper side base and the lower side base respectively engage the slider in a sliding manner on the opposite upper and lower lateral guide rails of the two support members; the advance and retreat changing mechanism is disposed such that the upper side base The seat and the lower base are respectively changed in the front-rear direction; the claws are pressed so that the sliders on both sides are slidably engaged with the longitudinal rails, and the longitudinal rails are disposed on the upper base And the lower base; and the lifting mechanism is arranged to raise and lower the two pressure claws.

As described above, according to the folding and dividing device for a panel of the present invention, the liquid crystal panel is supplied and conveyed to the belt conveyor with the A surface (CF surface) being the upper side.

Then, when the pre-processed cutting line of the A surface stops directly above and opposite the opposite ends of the folding and dividing plates, the opposite ends of the two folding dividing plates rise under the action of the lifting mechanism, The cutting line of the A side is divided by bending.

Next, when the liquid crystal panel conveyed forward is stopped, first, after the elevating mechanism lowers the backup lever, the moving body is moved by the reciprocating mechanism, and the tool is lowered by the elevating mechanism as the moving body moves forward. The cutting plane is cut by the cutter on the B side.

Thereafter, the swinging table is raised by the action of the moving mechanism. At this time, since the A-side of the liquid crystal panel is continuously pressed by the lowered backup lever, the tip end of the backup lever serves as a fulcrum, and the swinging table is bent while being divided (separated), and swings in the rising direction. The table is pressed in the downstream direction by the descending guide of the guiding mechanism.

Therefore, it is possible to avoid the contact of the liquid crystal panel at the split end portion at the bent divided portion of the panel (the portion which is separated between the downstream side and the upstream side of the backup lever), and with this avoidance, the exposure can be eliminated. The terminal portion (face) is subjected to interference splitting (separating the CF surface in a non-contact manner).

Further, the liquid crystal panel is supplied and transported to the belt conveyor with the B surface (TFT surface) being the upper side.

Further, regarding the front and rear bending and dividing the pallets, by moving the two moving stages in the away direction by the moving mechanism, a gap is provided between the opposite ends of the two folding dividing plates.

In this case, when the cutting line of the pre-processed side of the lower side A is stopped between the opposite ends of the folding and dividing plate, the folding and splitting lever is lowered by the lifting mechanism, and the cutting line of the A side is bent. The folding is divided, and the debris generated by the folding and splitting is sucked and recovered by the suction nozzle.

Next, after the elevating mechanism lowers the spare lever, the swinging table is lowered by the elevating mechanism.

At this time, the B-side of the liquid crystal panel is continuously pressed by the lowered backup lever. Therefore, the tip end of the backup lever serves as a fulcrum, the swinging table is lowered, and the bending is divided (separated), and the swinging operation in the downward direction is performed. The table is guided forward by the rising guide of the guiding mechanism.

Therefore, it is possible to avoid the contact of the liquid crystal panel at the split end portion at the bent divided portion of the panel (the portion which is separated between the downstream side and the upstream side of the backup lever), and with the avoidance of this contact, it is possible to eliminate The exposed terminal portion (face) is subjected to interference and division (separation).

That is, it has the following unique effects: it is possible to perform an extremely smooth folding and split without damaging the terminal faces without causing secondary products.

Further, since the bending by the oscillating table is divided into the separation by the torsion, there is a special effect that various problems caused by the known knocking with a large impact can be eliminated.

Further, after the edge of the liquid crystal panel is sandwiched by the upper and lower gripping claws, the swinging body is swung by the swinging action mechanism, and the gripping claws are tilted while the edges are bent and divided, so that the splitting is performed (Separate) is the twisting method. Therefore, it has the unique effect of eliminating various problems caused by the knocking.

In addition, since the edge of the liquid crystal panel is continuously pressed by the upper and lower pressing claws, the bending and the dividing are performed, so that the special effect of eliminating various problems due to the knocking can be eliminated, and the upper side and the lower side having the breaking claw can be provided. Since the side base is changed in position in the front-rear direction, the bending division position can be freely changed.

Further, in addition to the above effects, it is also possible to perform the folding and dividing of the front edge and the rear edge of the liquid crystal panel in the flow in one direction.

Next, a first embodiment of the present invention will be described based on the drawings.

The liquid crystal panel A which is bent and divided in the embodiment of the present invention is, for example, a liquid crystal panel having a laminated structure of a CF unit substrate, a liquid crystal as an electrode, and a TFT unit substrate, and the liquid crystal panel of the large sheet is sequentially bent. A single LCD panel that is divided into large LCD panels and product sizes.

Further, when the liquid crystal panel A is divided and divided, the CF substrate 1 on the A side is placed on the upper side (because it is a non-contact method) or the TFT substrate 2 on the B side is on the upper side. When the CF substrate 1 on the A side is the upper side, as shown in FIG. 1 and FIG. 2, on the upper surface (surface) of the CF substrate 1, the cutting line 3 in the XY direction is cut in the front process. Further, when the TFT substrate 2 on the B surface is the upper side, as shown in FIGS. 3 and 4, the upper surface (surface) of the TFT substrate 2 and the lower surface (surface) of the CF substrate 1 are drawn in the front process. The cutting lines 4 and 5 in the XY direction are cut out.

The bending division of the above-mentioned large-sized liquid crystal panel A will be described based on FIGS. 5 to 10. The liquid crystal panel A is transported by the belt conveyor 11.

Further, on the upper side of the carrying-side head of the belt conveyor 11, a bending split lever 13 which is guided by a guide which is lifted and lowered by the lifting mechanism 12 is provided, and a suction nozzle 14 which is located at the folding split lever 13 is provided. The front and rear sides are attracted to the debris generated by the bending and splitting performed by the bending split rod 13.

As shown in FIGS. 6 and 7, the bending split lever 13 is supported by a cylinder serving as the elevating mechanism 12 in a horizontal portion of the portal frame 15 that straddles the belt conveyor 11, and is lifted and lowered by the action of the cylinder.

Further, as shown in Figs. 6 and 7, the suction nozzle 14 is provided with a hollow casing before and after the folding of the split rod 13 (upstream and downstream of the belt conveyor 11), and is connected to the casing via communication with the casing. The body hose (not shown) is attracted.

Next, as shown in FIG. 7, on the guide rail 16 which is laid in the moving direction of the belt conveyor 11, the slider 17 at the lower end of both sides of the gate-shaped frame 15 is slidably engaged, and the pair is passed. The fixed motor 49 is reversibly driven to drive the screw of the nut 18 screwed into the lower ends of the portal frame 15 In this way, the bending split lever 13 can be moved in the downstream and upstream directions together with the door frame 15, and the adjustment of the position of the press bending division of the bending split lever 13 and the position of the cutting line 5 can be performed. (This adjustment is to read the mark of the liquid crystal panel A of a known type by a video camera (not shown), and move the door frame 15 with this reading).

Further, just below the bending split lever 13, on the back side of the carrying side of the belt conveyor 11, as shown in Figs. 6 and 8 and 9, a moving table 20, 21 disposed before and after is provided, and the moving table 20, 21 The moving mechanism B is used to approach and away from sliding.

In the illustrated case, the moving mechanism B is provided on the lower surfaces of the two moving stages 20 and 21 so as to be slidably engaged with the guide rails 23 by the guide rails 23 provided in the front-rear direction of the base 22 The slider 24 and the cylinder 26 that is supported by the base 22 via the arm 25 and coupled to each of the moving stages 20 and 21 are configured to move the two moving stages 20 and 21 by the action of the air cylinder 26, but may pass ( Other components of the mobile mechanism B are used to achieve the goal.

Further, the folding and dividing plates 28 and 29 are provided on the two moving tables 20 and 21 so that the front end edges of the bending dividing plates 28 and 29 face each other, and one upstream end is provided by the pin 27 as a swinging fulcrum. Rotating with the downstream end of the other side, the two split dividing plates 28, 29 are caused by the cylinders 30 as moving means mounted on the moving tables 20, 21, so that the two folding dividing plates 28, 29 are undulating swing.

Further, the front and rear suction nozzles 14, 14 are supported by the arms 31 rising from the moving tables 20, 21.

Next, as shown in FIGS. 5 and 6, the slider 34 provided on the lower surface of the slide table 33 is slidably engaged with the guide rail 32 in the front-rear direction, and the guide rail 23 is provided on the slide table 33 to pass The screw 36 that is driven by the reversible operation of the stationary motor 35 is screwed into the nut 37 of the slide table 33.

In this way, the motor 35 can be operated by the mark reading by the camera, and the bending division position of the bending split lever 13 and the alignment of the cutting lines 3 and 4 can be adjusted.

Further, as shown in FIGS. 5, 10, and 11, on the front side of the head of the belt conveyor 11, a guide rail 40 that traverses the belt conveyor 11 is provided below the liquid crystal panel A, and a scribing line is provided. The cutter 43 is lifted and lowered by the cylinder 42 as an elevating mechanism that is slidably engaged with the slider 41 of the guide rail 40, and is driven by reversible operation of the stationary motor 44. The screw 45 is screwed into the nut 46 of the slider 41, so that the cutter 43 can be reciprocated together with the slider 41, and the cutter 43 can be raised by, for example, the cylinder 42 as an elevating mechanism with the unidirectional movement of the slider 41. The cutter 43 cuts the cutting line 8 for separating the liquid crystal panel A into the large panel a on the lower surface of the TFT substrate 2 on the B surface of the liquid crystal panel A.

Further, a backup lever 48 that is lifted and lowered by a cylinder 47 as an elevating mechanism is provided above the cutter 43 on the upper side of the liquid crystal panel A.

In addition, the mark of the scribe line position of the tool 43 is sometimes read by the camera, and is adjusted along with the reading so that the tool 43 (the spare lever 48 is also the same) is aligned with the scribe line position (for example, by splitting with the bend) The position of the rod 13 is adjusted to the same configuration, etc.).

The backup lever 48 allows the slider 53 provided below from the upper surface of the backup lever 48 to be slidably engaged with the longitudinal rail 52 provided on the gate frame 51 to guide the lift.

Further, in front of the cutter 43, an oscillating table C is provided, and the liquid crystal panel A is transported from the belt conveyor 11 to the front auxiliary table 54 and slid, and then transferred to the upper surface of the oscillating table C for reception.

Further, when the auxiliary table 54 is provided around the head pulley of the belt conveyor 11 and can be rotated along the pulley (the rotation function is omitted), it can be avoided in the descending direction.

On the lower side of the swinging table C, a moving table 55 in the front-rear direction is provided. The moving table 55 in the front-rear direction causes the sliders 17 at both ends to be slidably engaged with the guide rail 16, and the moving table 55 utilizes the AND gate. The frame 15 is a reversible operation by the motor 56 having the same configuration, and can be adjusted in the front-rear direction by the screw 57 and the nuts 58 provided on the movable table 55 by screwing the screw 57.

The reason for this movement adjustment is that the bending division position described later can be read by the camera, and the position adjustment (bending division position) is performed along with this reading.

The oscillating table C is oscillated in the vertical direction by a cylinder 59, which is an elevating mechanism attached to the moving table 55, for example.

Further, a guide mechanism D having an ascending guide portion T is provided on both sides of the swinging table C near the lower side backup lever, and the ascending guide portion T is oscillated in the descending direction with the action of the air cylinder 59. Swing, and the oscillating table C slides forward.

As shown in FIGS. 5, 6, and 11, the above-described guide mechanism D is constituted by an arc-shaped elongated hole 63 and a rotary member 64 which is provided to cause the rail member 62 to be slid from the belt conveyor 11 of the table C. The lower surface of the head side corners protrudes downward, and the upper and lower sides of the rail member 62 face obliquely rearward; the rotating member 64 is supported by the moving table 55 and embedded in the elongated hole 63; the upper half of the long hole 63 is The rising guide portion T and the lower half of the long hole 63 are the lowering guide portions S.

Further, the rotating member 65 supported by the bearing at the projecting end of the cylinder 59 is brought into contact with the lower surface of the swinging table C to reduce the frictional resistance.

Further, the bent split panel on the swing table C is sent out by the belt conveyor 66.

Further, as shown in Fig. 5, a plurality of juxtaposed grooves 71 along the moving direction of the belt conveyor 11 are provided on the upper surfaces of the two bent dividing plates 28, 29, and the inside of the grooves 71 (connection suction hose) By suction, the liquid crystal panel A is sucked and held on the conveyor belt by providing a plurality of through holes 72 in the conveyor belt of the belt conveyor 11, thereby preventing the liquid crystal panel A on the conveyor belt from slipping. As a result, it is possible to perform the suction. Accurate bending and segmentation.

Next, the bending division using the bending and dividing device having the above configuration will be described.

The liquid crystal panel A is supplied to the belt conveyor 11 with the A surface (CF substrate 1) as the upper side (see FIG. 1).

When the preceding cutting line 3 of the liquid crystal panel A reaches the position in which the front end is closed (as shown in FIG. 8) and the front end edges of the folding and dividing plates 28 and 29 are stopped directly above, the two folding and folding plates are stopped. 28 and 29 rise as shown in Fig. 9 under the action of the elongation of the cylinder 30.

Thus, as shown in FIG. 9 and FIG. 13(b), it is divided and divided (separated). This bending division is to sequentially separate the cutting lines 3.

When the bending of the cutting line 3 is completed and the liquid crystal panel A is transported to the front and stopped, first, under the action of the extension of the air cylinder 47, the backup lever 48 is lowered and the tip end of the backup lever 48 is pressed. A side (surface) of the liquid crystal panel A.

In this case, the slider 41 is reciprocated by the reversible operation of the motor 44, and at the time of the outward movement, the cutter 43 is raised by the elongation of the cylinder 42, and the lower surface of the TFT substrate 2 on the B surface is cut. The cutting line 8 is taken out (see (c) of Fig. 13).

Of course, the cutter 43 is lowered and restored under the contraction of the cylinder 42 at the return stroke of the slider 41.

Further, when the liquid crystal panel A is conveyed, the backup lever 48 is lifted and restored by the contraction of the air cylinder 47.

Further, the backup lever 48 is lowered when bending is performed by the swing table C to be described later (as shown in FIG. 17).

Then, when the liquid crystal panel A (see FIG. 11) sent to the front is stopped, the swinging table C in the horizontal posture shown in FIG. 14 is swung upward by the extension of the air cylinder 59, and therefore, the swing table C is oscillated. The liquid crystal panel A also rises, and along with this rise, the cutting line 8 is bent and divided as shown in FIG.

At this time, the swinging piece 64 in the long hole 63 of the guiding mechanism D moves along the lowering guide portion S, and the swinging table C moves forward.

Thus, as shown in (d) of FIG. 13, the bent end edge floats on the opposite side, so that the contact of the electrodes is prevented, and as shown in (e) of FIG. 13, the large liquid crystal panel is sent out at the belt conveyor 66. A-1 (shown in Figure 2) can eliminate electrode damage with avoidance of contact.

Further, as shown in Figs. 15, 16 and 17, when the bending division auxiliary lever 82 is provided on the outer side of the swing table C, the bending division auxiliary lever 82 is acted upon by the cylinder 81 attached to the moving table 55. When the upper side is inclined rearward, the lower surface of the B surface of the liquid crystal panel A can be supported by the projecting end surface of the bending and dividing auxiliary lever 82, and the smooth folding can be performed.

Further, the bulk liquid crystal panel A-1 which has been bent and divided is sent to the conveyor 66 from the swinging table C which has been restored to the predetermined position, and after being sent out, is discharged by the standby transfer machine (not shown). under.

Next, the bending division of the B surface (TFT substrate 2) of the liquid crystal panel A as the upper side will be described based on FIG.

At this time, on the lower side A surface (the lower surface of the CF substrate 1), the cutting line 5 is formed by the pretreatment, and the cutting line 4 is formed on the upper side B surface (the TFT substrate 2) by the pretreatment.

The liquid crystal panel A is supplied to the belt conveyor 11 and conveyed, and the cutting line 5 is stopped immediately below the bending split rod 13 in accordance with this conveyance.

At this time, under the contraction of the air cylinder 26, the moving stages 20, 21 are moved away from each other, and a gap is provided between the opposite ends of the two divided dividing plates 28, 29 as shown in Fig. 18.

In this case, the bending split lever 13 is lowered by the extension of the cylinder as the elevating mechanism 12, and the downward pressure acts on the B surface of the liquid crystal panel A, as shown in (b) of FIG. Line 5 is divided by bending.

Then, the liquid crystal panel A is sent to the swing table C, and then the tip end of the backup lever 48 which is lowered by the extension of the air cylinder 47 is as shown in Fig. 20 and the upper surface of the liquid crystal panel A (the TFT on the B side) The substrate 2 faces) abuts.

Then, the oscillating table C is lowered by the action of the air cylinder 59 as the elevating mechanism, as shown in FIG. 20 to FIG. 21, and as shown in FIG. 23(c), the cutting line 4 is bent and divided (separated).

At this time, since the rotary member 64 moves along the ascending guide portion T of the guide mechanism D, the tilting inclined table C is to be moved forward (as shown in FIG. 22), so that it does not correspond to (c) of FIG. As shown in the figure, the exposed electrode contact at the separated edge which is separated by the bending division is brought into contact, and the large liquid crystal panel A-1 which is bent and divided in the non-contact state is as shown in FIG. 23(d) The conveyor 66 is delivered. Therefore, the electrode exposed by the split and separated edges is not damaged.

Further, the bent and divided large liquid crystal panel A-1 is bent into small pieces (single separation) of the product size by using the bending division device of the present invention. At this time, of course, it is possible to perform the bending division of the terminal without loss.

Since the bending of the A surface and the B surface of the swinging table C is divided by the twisting, even a thinned panel such as the recent liquid crystal panel can be smoothly broken. No secondary products will be produced.
