Description

  The present invention relates to a device for splitting (splitting) a liquid crystal panel.

  Various methods are already known as conventional methods for obtaining a product-sized panel by sequentially breaking a large liquid crystal panel. (For example, see Patent Documents 1, 2, and 3).

Japanese Patent No. 3759450 Japanese Patent No. 3969992 Japanese Patent No. 5256554

By the way, the split for the division | segmentation of patent document 1 is a hitting splitting system using a bar material or a roll.
The split in Patent Document 2 is a hitting method using a roll as a split member.
The split in Patent Document 3 is a hitting method using a folding bar.

When the above-described splitting method is adopted for panel splitting in recent times, various problems occur.
In other words, recent liquid crystal panels have a very fine structure (by reducing the thickness of each laminated substrate and electrode film as much as possible to reduce weight and cost). Cracks may occur in parts other than the split, causing defective products, and because the internal wiring is fine, disconnection occurs due to impact of hitting, etc., resulting in defective products. Accordingly, it is necessary to remove the adhered cullet.

  In particular, the terminal material is removed to remove the edge material along with the split and expose the electrode to the edge of the panel. At this time, the edge material of the unnecessary material (waste material) is removed from the exposed panel surface. When the sliding movement is performed while in contact with the terminal, the terminal surface is damaged (disconnected), resulting in a defective product.

  Also, when the edge of the liquid crystal panel (because of the ear drop) is split (divided), if the above-described splitting method is used, cracks will occur in the part other than the split due to the splitting, resulting in a defective product. In addition, problems such as disconnection occur due to the impact of hitting.

  Accordingly, the present invention is to provide a liquid crystal panel splitting device that solves the above-described problems.

  In order to solve the above-mentioned problems, the present invention is directed to a belt conveyor provided to convey a liquid crystal panel and a break provided to be raised and lowered by an elevating means at a front upper folding position of a carrier side head of the belt conveyor. A bar, a nozzle provided on the outside of the break bar for sucking the generated cullet, and a moving table that is arranged below and below the break bar on the lower side of the carrier belt of the belt conveyor and slides toward and away by the moving means. A break plate provided to rotatably support the opposite ends of the two moving bases, and each of which lifts the opposite tip by lifting means, and the liquid crystal panel on the front side of the head of the belt conveyor. The liquid crystal panel is lifted by a lifting / lowering means on a traveling body provided to travel by a reciprocating traveling means in the bottom surface width direction. A cutter provided to scribe a cutting line on a lower surface of the liquid crystal, a backup bar provided to be lowered by an elevating means immediately above the scribe line by the cutter and press down the upper surface of the liquid crystal panel, and the above in front of the cutter A swing table provided so that the liquid crystal panel is transferred and received, lifting means provided so as to swing the swing table in the vertical direction, and a swing table formed by front and rear lifting means on the backup bar side below the swing table. A configuration is adopted which comprises guide means having a rising guide provided so that the swing table slides forward in accordance with the downward swing.

  Further, a configuration is adopted in which the guide means is formed by a combination with a lowering guide extending downward from the ascending guide so that the swing table slides forward in accordance with the swinging direction of the swing table by the elevating means.

  A first load receiving means and a second load receiving means provided at the front and rear so as to receive the supply liquid crystal panel; and a support member provided so as to stand on both sides between the first load receiving means and the second load receiving means; An oscillating body that is pivotally supported on the opposite inner side surfaces of the both supporting members via a support shaft in the middle of both ends, and a slider that is engaged with the rail on the upper end side of the both oscillating bodies; A base that is slid in the front-rear direction, advancing / retracting means that allows the position to be changed by sliding the base in the front-rear direction, and a vertical rail provided on the lower end side of the oscillator and the base A gripping claw that is slidably engaged with sliders on both sides, and a lifting / lowering means provided to raise and lower both the holding claws, and a swing provided to swing the rocking body in the front-rear direction. A configuration comprising operating means To use.

  A first load receiving means and a second load receiving means provided at the front and rear to receive the supply liquid crystal panel; and a support member provided to stand on both sides between the first load receiving means and the second load receiving means; The upper base and the lower base, in which the sliders are slidably engaged with the lateral rails of the upper and lower opposing surfaces of the support members, respectively, and the positions of the upper base and the lower base are changed in the front-rear direction. An advancing / retreating change means provided to the upper base and the lower base, and a split claw that is vertically arranged by slidably engaging sliders on both sides with the vertical rail provided on the upper base and the lower base; The structure which consists of raising / lowering means provided so that a nail | claw may be raised / lowered is employ | adopted.

  As described above, according to the panel splitting device of the present invention, the liquid crystal panel is supplied and conveyed on the belt conveyor so that the A side (CF surface) is on the upper side.

  When the pre-processed cutting line on the A surface stops immediately above the opposing ends of the front and rear break plates, the opposing ends of both break plates are raised by the action of the lifting means, so that the cutting line on the A surface is broken.

  Next, when the liquid crystal panel conveyed forward is stopped, the backup bar is first lowered by the elevating means, and then the traveling body is caused to travel by the reciprocating traveling means, and the cutter is lowered by the elevating means as the traveling body moves forward, Scribing a cutting line on the B surface with the cutter.

Thereafter, the swing table is raised by the action of the traveling means.
At this time, the A-side of the liquid crystal panel is continuously pushed by the descending backup bar, so that the swing table is broken (divided) while ascending with the tip of the backup bar as a fulcrum, while it rises. The swing table that swings in the direction is pushed downstream by the lowering guide of the guide means.

  For this reason, while avoiding the contact of the liquid crystal panel split end at the panel folded portion (the portion divided between the downstream side and the upstream side of the backup bar), the exposed terminal portion (surface) ) Can be broken (the CF surface is divided by a no-touch method).

  Further, the liquid crystal panel is supplied and conveyed on the belt conveyor so that the B surface (TFT surface) is on the upper side.

  On the other hand, the front and rear break plates are slid in the direction away from each other by the action of the moving means, and a gap is provided between the opposing ends of both break plates.

  In this situation, when the preprocessed cutting line on the lower A surface stops between the opposing ends of the break plate, the break bar descends by the lifting means, breaks the cutting line on the A surface, and removes the cullet accompanying the break. Collect while suctioning with a suction nozzle.

  Thus, after the backup bar is lowered by the elevating means, the swing table is lowered by the elevating means.

  At this time, since the back-up bar that has been lowered continues to push the B side of the liquid crystal panel, the tip of the backup bar becomes the fulcrum, and the swing table is broken (divided) while descending, while the descent The swing table that swings in the direction is pushed forward by the ascending guide of the guide means.

  For this reason, while avoiding the contact of the liquid crystal panel split end at the split portion of the panel (the portion divided between the downstream side and the upstream side of the backup bar), the exposed terminal portion ( Folding (splitting) that eliminates interference on the surface) is possible.

  That is, there is a unique effect of eliminating the generation of defective products that do not damage the terminal surface, together with extremely smooth folding.

  In addition, since the splitting by the swing table is divided by twisting, there is a specific effect that can eliminate various problems such as the known striking with a large impact.

Furthermore, after the edge of the liquid crystal panel is clamped by the upper and lower gripping claws, the edge is split while the gripping claws under the clamping are tilted while the rocking body is swung by the swinging action means. ) Becomes a twist method.
For this reason, there exists a peculiar effect which eliminates various inconveniences, such as hitting.

  In addition, the squeeze breaks while continuing to push the edge of the liquid crystal panel with the upper and lower split claws, so that it has a unique effect of eliminating various inconveniences such as hitting, and the upper and lower sides having the split claws. Since the position of the base can be changed in the front-rear direction, the folding position can be changed freely.

  In addition to the above, the leading edge and trailing edge folding of the liquid crystal panel can also be performed in one direction of flow.

In this case, as shown in FIGS. 3 and 4, cutting lines 4 and 5 in the XY directions are scribed on the upper surface (front surface) of the TFT substrate 2 and the lower surface (front surface) of the CF substrate 1 in the previous step.

The folding of the large liquid crystal panel A will be described with reference to FIGS.
The liquid crystal panel A is conveyed by the belt conveyor 11.

  Further, on the upper side of the belt conveyor 11 in front of the carrier-side head, there is a break bar 13 guided by a guide 50 that is moved up and down by an elevating means 12, and a break bar 13 that is positioned before and after the break bar 13. There is provided a nozzle 14 for sucking the cullet generated accordingly.

  As shown in FIGS. 6 and 7, the break bar 13 is supported on a horizontal portion of the portal frame 15 straddling the belt conveyor 11 via a cylinder as the lifting means 12, and is lifted and lowered by the action of the cylinder.

  Further, as shown in FIGS. 6 and 7, the nozzle 14 is a hose (not shown) in which a hollow box is arranged before and after the break bar 13 (upstream and downstream of the belt conveyor 11) and communicated with the box. (Not shown).

  As shown in FIG. 7, the sliders 17 at both lower ends of the portal frame 15 are slidably engaged with rails 16 laid in the running direction of the belt conveyor 11, and female screws at both lower ends of the portal frame 15 are slidably engaged. The breaker 13 is moved together with the gate-shaped frame 15 in the downstream and upstream directions by reversibly driving the stationary motor 49 with the male screw 19 screwed in 18, and the pressure by the breakbar 13 is moved to the position of the cutting line 5. Adjustment to match the folding position (this adjustment is made by reading a mark of the liquid crystal panel A of a known method by a camera (not shown) and moving the gate-shaped frame 15 in accordance with this reading).

  Further, as shown in FIGS. 6, 8, and 9, on the carrier-side back surface of the belt conveyor 11, just below the break bar 13, as shown in FIGS. Is provided.

  In the illustrated case, the moving means B includes a rail 23 in the front-rear direction provided on the base 22 and a slider 24 provided on the lower surfaces of the two moving bases 20 and 21 so as to be slidably engaged with the rail 23. In addition to supporting the base 22 via the arm 25 and the cylinders 26 connected to the respective moving bases 20 and 21, both the moving bases 20 and 21 are moved by the action of the cylinder 26. The object can also be achieved by the configuration (of the moving means B).

  Furthermore, on both the moving bases 20 and 21, a break plate 28 that turns up and down via a pin 27 as a swing fulcrum with one upstream end and the other downstream end facing each other with the leading edge opposed. 29. The two break plates 28, 29 are configured to swing the two break plates 28, 29 up and down by the action of a cylinder 30 as a moving means installed on the moving tables 20, 21.

  The front and rear suction nozzles 14 and 14 are supported by the arms 31 that rise from the movable bases 20 and 21.

The male screw 36 driven by the reversible operation is screwed into the female screw 37 of the slide base 33.

  Then, it is possible to adjust the break position by the break bar 13 and the cutting lines 3 and 4 by operating the motor 35 as the mark is read by the camera.

  As shown in FIGS. 5, 10, and 11, a guide rail 40 that crosses the belt conveyor 11 is provided on the lower surface of the liquid crystal panel A on the front side of the head of the belt conveyor 11. A scribe cutter 43 that is lifted and lowered by a cylinder 42 as a lifting means on the combined slider 41 is provided, and a male screw 45 for reversible operation of the stationary motor 44 is screwed into a female screw 46 of the slider 41, thereby While the cutter 43 reciprocates, the cutter 43 is lifted by, for example, a cylinder 42 as an elevating means in accordance with the travel of the slider 41 in one direction, whereby the liquid crystal panel A has a liquid crystal on the lower surface of the TFT substrate 2 on the B surface. A cutting line 8 for dividing the panel A into the large panel a can be scribed.

  Further, a backup bar 48 that is lifted and lowered by a cylinder 47 as a lifting means is provided immediately above the cutter 43 and above the liquid crystal panel A.

  The mark of the scribe position by the cutter 43 is read by the camera, and the cutter 43 (as well as the backup bar 48) coincides with the scribe position accompanying this reading (for example, the position adjustment of the break bar 13 has the same configuration, etc.) May be adjusted).

  The backup bar 48 guides the ascending and descending by causing the slider 53 provided below the upper edge of the plate surface of the backup bar 48 to slidably engage with the vertical rail 52 provided on the portal frame 51.

  Further, in front of the cutter 43, there is provided a swing table C on which the liquid crystal panel A is slid on the front auxiliary table 54 from the belt conveyor 11 and receives the cargo.

  If the auxiliary table 54 is provided so as to be able to turn around the head pulley of the belt conveyor 11 (the turning function is not shown), it can be retracted in the descending direction.

  Below the swing table C is provided a moving table 55 in the front-rear direction in which the sliders 17 at both ends are slidably engaged with the rails 16. The moving table 55 has the same configuration as that of the portal frame 15. It is possible to adjust the movement in the front-rear direction by a male screw 57 that is driven by reversible operation of the motor 56 and a female screw 58 provided on both sides of the moving base 55 so that the male screw 57 is screwed.

  The cause of this movement adjustment is that a break position (to be described later) is read by a camera, and the position adjustment (break position) can be adjusted along with this reading.

  The swing table C is swung in the vertical direction by the action of, for example, a cylinder 59 as a lifting means installed on the movable table 55.

  Further, on both sides close to the lower backup bar of the swing table C, there are guide means having a lifting guide 61 that causes the swing table C to slide forward in accordance with the swing in the descending direction of the swing table C due to the action of the cylinder 59. D is provided.

  As shown in FIGS. 5, 6, and 11, the guide means D projects a rail material 62 downward from the lower surfaces of both head-side corners of the belt conveyor 11 of the swing table C, Are formed with an arc-shaped long hole 63 provided so as to face obliquely backward, and a rotor 64 that is supported by the moving base 55 and fitted into the long hole 63, and the upper half of the long hole 63 serves as a rising guide T, The lower half of the long hole 63 is a lowering guide S.

  Note that the frictional resistance is reduced by bringing the trochanter 65 supported at the end of the cylinder 59 in the protruding direction into contact with the lower surface of the swing table C.

  Further, the folded panel on the swing table C is paid out by the belt conveyor 66.

  As shown in FIG. 5, a plurality of parallel grooves 71 along the traveling direction of the belt conveyor 11 are provided on the upper surfaces of the break plates 28 and 29, and the inside of the grooves 71 (with suction hoses connected) is sucked. At the same time, by providing a number of through holes 72 in the belt of the belt conveyor 11, the liquid crystal panel A is sucked and held on the belt to prevent the liquid crystal panel A from slipping on the belt. Can be split.

Next, splitting using the splitting device having the above configuration will be described.
The liquid crystal panel A is supplied onto the belt conveyor 11 with the A side (CF substrate 1) facing upward (see FIG. 1).

  When the preceding cutting line 3 of the liquid crystal panel A reaches and stops immediately above the leading edges of the break plates 28 and 29 in the closed posture (shown in FIG. 8) at the opposite ends, both the break plates 28 are stretched by the cylinder 30. 29 rises as shown in FIG.

Then, as shown in FIG. 9 and FIG.
This splitting sequentially cuts the cutting line 3.

  When the broken liquid crystal panel A of the cutting line 3 is conveyed forward and stopped, the backup bar 48 is first lowered by the extending action of the cylinder 47, and the A surface (front surface) of the liquid crystal panel A is moved from the tip of the backup par 48. Hold down.

  Under this condition, the slider 41 is reciprocated by the reversible operation of the motor 44, and the cutter 43 is lifted by the extension action of the cylinder 42 in the forward direction, so that the cutting line 8 is formed on the lower surface of the B-side TFT substrate 2 (FIG. 13). (See (c) of).

  Of course, the cutter 43 is lifted and restored by the contraction action of the cylinder 42 when the slider 41 returns.

  Further, the backup bar 48 is raised and returned (as shown in FIG. 17) by the contraction action of the cylinder 47 when the liquid crystal panel A is transported.

  The backup bar 48 is lowered (as shown in FIG. 17) when it is split by a swing plate C described later.

  When the liquid crystal panel A fed forward stops (see FIG. 11), the swing table C having a horizontal posture as shown in FIG. The liquid crystal panel A also rises, and along this rise, the cutting line 8 is broken as shown in FIG.

  At this time, as the rotor 64 in the long hole 63 of the guide means D moves to the lowering guide S, the swing table C moves forward.

  Then, as shown in FIG. 13 (d), the contact of the electrodes is avoided by the floating of the surface facing the split edge, and as shown in FIG. 13 (e), the large liquid crystal panel A by the belt conveyor 66 is obtained. -1 (shown in FIG. 2) can eliminate the damage to the electrode due to contact avoidance.

  As shown in FIGS. 15, 16 and 17, if a break auxiliary bar 82 is provided on the outer side of the swing table C and the tip is directed obliquely rearward and upward due to the action of the cylinder 81 installed on the movable table 55, Sometimes, the lower end of the B surface of the liquid crystal panel A is supported by the protruding end surface of the break auxiliary bar 82, so that smooth splitting can be performed.

  The split large liquid crystal panel A is sent to the conveyor 66 from the swing table C returned to the fixed position, and is removed by a standby transfer machine (not shown) after the feeding.

Next, the folding with the B surface (TFT substrate 2) of the liquid crystal panel A on the upper side will be described with reference to FIG.
At this time, the cutting line 5 is pretreated on the lower A surface (lower surface of the CF substrate 1), and the cutting line 4 is pretreated on the upper B surface (TFT substrate 2).

  The liquid crystal panel A is supplied and conveyed on the belt conveyor 11, and the cutting line 5 accompanying this conveyance stops just below the break bar 13.

  At this time, due to the contraction action of the cylinder 26, the movable bases 20 and 21 are slid away from each other, and a gap is provided between the opposing ends of the break plates 28 and 29 as shown in FIG.

  Under this condition, the break bar 13 is lowered by the extending action of the cylinder 12, so that a downward pressing force acts on the B surface of the liquid crystal panel A, and the cutting line 5 is folded as shown in FIG. Divided.

  Then, the liquid crystal panel A is fed onto the swing table C, and then the tip of the backup bar 48 lowered by the extending action of the cylinder 47 is placed on the upper surface of the liquid crystal panel A (on the surface of the TFT substrate 2 on the B surface) as shown in FIG. ) Abut.

  Accordingly, by lowering the swing table C as shown in FIGS. 20 to 21 by operating the cylinder 59 as the lifting means, the cutting line 4 is broken (divided) as shown in FIG. Is done.

At this time, since the rotor 64 moves to the ascending guide 61 of the guide means D, the swinging table C that descends and tilts tends to move forward (as shown in FIG. 22). As shown in FIG. 23 (d), the large-size panel A-1 which is not contacted with the exposed electrodes due to the split edges separated by the splitting and is not contacted is paid out by the belt conveyor 66.
Therefore, the electrode exposed at the split edge is not damaged.

In addition, the large-sized liquid crystal panel A-1 which has been split is divided into small pieces (divided into single pieces) using the splitting device of the present invention.
At this time, naturally, the terminal can be broken intact.

  The splitting of the A side and the B side using the swing of the above-mentioned swing table C is all divided due to twisting, so that even a thin plate like a recent liquid crystal panel is very smooth and defective. Occurrence can be eliminated.

  In the splitting step, the lower surface is split (divided) by the break bar 13 with respect to the scribed substrate (1 and 2) on both the A and B sides.

  The present invention relates to a device for splitting (splitting) a liquid crystal panel.

  Various methods are already known as conventional methods for obtaining a product-sized panel by sequentially breaking a large liquid crystal panel. (For example, see Patent Documents 1, 2, and 3).

Japanese Patent No. 3759450 Japanese Patent No. 3969992 Japanese Patent No. 5256554

By the way, the split for the division | segmentation of patent document 1 is a hitting splitting system using a bar material or a roll.
The split in Patent Document 2 is a hitting method using a roll as a split member.
The split in Patent Document 3 is a hitting method using a folding bar.

When the above-described splitting method is adopted for panel splitting in recent times, various problems occur.
In other words, recent liquid crystal panels have a very fine structure (by reducing the thickness of each laminated substrate and electrode film as much as possible to reduce weight and cost). Cracks may occur in parts other than the split, causing defective products, and because the internal wiring is fine, disconnection occurs due to impact of hitting, etc., resulting in defective products. Accordingly, it is necessary to remove the adhered cullet.

  In particular, the terminal material is removed to remove the edge material along with the split and expose the electrode to the edge of the panel. At this time, the edge material of the unnecessary material (waste material) is removed from the exposed panel surface. When the sliding movement is performed while in contact with the terminal, the terminal surface is damaged (disconnected), resulting in a defective product.

  Also, when the edge of the liquid crystal panel (because of the ear drop) is split (divided), if the above-described splitting method is used, cracks will occur in the part other than the split due to the splitting, resulting in a defective product. In addition, problems such as disconnection occur due to the impact of hitting.

  Accordingly, the present invention is to provide a liquid crystal panel splitting device that solves the above-described problems.

  In order to solve the above-mentioned problems, the present invention is directed to a belt conveyor provided to convey a liquid crystal panel and a break provided to be raised and lowered by an elevating means at a front upper folding position of a carrier side head of the belt conveyor. A bar, a nozzle provided on the outside of the break bar for sucking the generated cullet, and a moving table that is arranged below and below the break bar on the lower side of the carrier belt of the belt conveyor and slides toward and away by the moving means. A break plate provided to rotatably support the opposite ends of the two moving bases, and each of which lifts the opposite tip by lifting means, and the liquid crystal panel on the front side of the head of the belt conveyor. The liquid crystal panel is lifted by a lifting / lowering means on a traveling body provided to travel by a reciprocating traveling means in the bottom surface width direction. A cutter provided to scribe a cutting line on a lower surface of the liquid crystal, a backup bar provided to be lowered by an elevating means immediately above the scribe line by the cutter and press down the upper surface of the liquid crystal panel, and the above in front of the cutter A swing table provided so that the liquid crystal panel is transferred and received, lifting means provided so as to swing the swing table in the vertical direction, and a swing table formed by front and rear lifting means on the backup bar side below the swing table. A configuration is adopted which comprises guide means having a rising guide provided so that the swing table slides forward in accordance with the downward swing.

  Further, a configuration is adopted in which the guide means is formed by a combination with a lowering guide extending downward from the ascending guide so that the swing table slides forward in accordance with the swinging direction of the swing table by the elevating means.

  As described above, according to the panel splitting device of the present invention, the liquid crystal panel is supplied and conveyed on the belt conveyor so that the A side (CF surface) is on the upper side.

  When the pre-processed cutting line on the A surface stops immediately above the opposing ends of the front and rear break plates, the opposing ends of both break plates are raised by the action of the lifting means, so that the cutting line on the A surface is broken.

  Next, when the liquid crystal panel conveyed forward is stopped, the backup bar is first lowered by the elevating means, and then the traveling body is caused to travel by the reciprocating traveling means, and the cutter is lowered by the elevating means as the traveling body moves forward, Scribing a cutting line on the B surface with the cutter.

Thereafter, the swing table is raised by the action of the traveling means.
At this time, the A-side of the liquid crystal panel is continuously pushed by the descending backup bar, so that the swing table is broken (divided) while ascending with the tip of the backup bar as a fulcrum, while it rises. The swing table that swings in the direction is pushed downstream by the lowering guide of the guide means.

  For this reason, while avoiding the contact of the liquid crystal panel split end at the panel folded portion (the portion divided between the downstream side and the upstream side of the backup bar), the exposed terminal portion (surface) ) Can be broken (the CF surface is divided by a no-touch method).

  Further, the liquid crystal panel is supplied and conveyed on the belt conveyor so that the B surface (TFT surface) is on the upper side.

  On the other hand, the front and rear break plates are slid in the direction away from each other by the action of the moving means, and a gap is provided between the opposing ends of both break plates.

  In this situation, when the preprocessed cutting line on the lower A surface stops between the opposing ends of the break plate, the break bar descends by the lifting means, breaks the cutting line on the A surface, and removes the cullet accompanying the break. Collect while suctioning with a suction nozzle.

  Thus, after the backup bar is lowered by the elevating means, the swing table is lowered by the elevating means.

  At this time, since the back-up bar that has been lowered continues to push the B side of the liquid crystal panel, the tip of the backup bar becomes the fulcrum, and the swing table is broken (divided) while descending, while the descent The swing table that swings in the direction is pushed forward by the ascending guide of the guide means.

  For this reason, while avoiding the contact of the liquid crystal panel split end at the split portion of the panel (the portion divided between the downstream side and the upstream side of the backup bar), the exposed terminal portion ( Folding (splitting) that eliminates interference on the surface) is possible.

  That is, there is a unique effect of eliminating the generation of defective products that do not damage the terminal surface, together with extremely smooth folding.

  In addition, since the splitting by the swing table is divided by twisting, there is a specific effect that can eliminate various problems such as the known striking with a large impact.

  When the liquid crystal panel A is folded, the CF substrate 1 on the A side is placed on the upper side (because of the no-touch method), the TFT substrate 2 on the B side is turned on the upper side, and the CF substrate 1 on the A side is placed. In the case of the upper side, as shown in FIG. 1 and FIG. 2, the cutting line 3 in the XY direction is scribed on the upper surface (front surface) of the CF substrate 1 in the previous step, and the B-side TFT substrate 2 is on the upper side. In this case, as shown in FIGS. 3 and 4, cutting lines 4 and 5 in the XY directions are scribed on the upper surface (front surface) of the TFT substrate 2 and the lower surface (front surface) of the CF substrate 1 in the previous step.

The folding of the large liquid crystal panel A will be described with reference to FIGS.
The liquid crystal panel A is conveyed by the belt conveyor 11.

  Further, on the upper side of the belt conveyor 11 in front of the carrier-side head, there is a break bar 13 guided by a guide 50 that is moved up and down by an elevating means 12, and a break bar 13 that is positioned before and after the break bar 13. There is provided a nozzle 14 for sucking the cullet generated accordingly.

  As shown in FIGS. 6 and 7, the break bar 13 is supported on a horizontal portion of the portal frame 15 straddling the belt conveyor 11 via a cylinder as the lifting means 12, and is lifted and lowered by the action of the cylinder.

  Further, as shown in FIGS. 6 and 7, the nozzle 14 is a hose (not shown) in which a hollow box is arranged before and after the break bar 13 (upstream and downstream of the belt conveyor 11) and communicated with the box. (Not shown).

  As shown in FIG. 7, the sliders 17 at both lower ends of the portal frame 15 are slidably engaged with rails 16 laid in the running direction of the belt conveyor 11, and female screws at both lower ends of the portal frame 15 are slidably engaged. The breaker 13 is moved together with the gate-shaped frame 15 in the downstream and upstream directions by reversibly driving the stationary motor 49 with the male screw 19 screwed in 18, and the pressure by the breakbar 13 is moved to the position of the cutting line 5. Adjustment to match the folding position (this adjustment is made by reading a mark of the liquid crystal panel A of a known method by a camera (not shown) and moving the gate-shaped frame 15 in accordance with this reading).

  Further, as shown in FIGS. 6, 8, and 9, on the carrier-side back surface of the belt conveyor 11, just below the break bar 13, as shown in FIGS. Is provided.

  In the illustrated case, the moving means B includes a rail 23 in the front-rear direction provided on the base 22 and a slider 24 provided on the lower surfaces of the two moving bases 20 and 21 so as to be slidably engaged with the rail 23. In addition to supporting the base 22 via the arm 25 and the cylinders 26 connected to the respective moving bases 20 and 21, both the moving bases 20 and 21 are moved by the action of the cylinder 26. The object can also be achieved by the configuration (of the moving means B).

  Furthermore, on both the moving bases 20 and 21, a break plate 28 that turns up and down via a pin 27 as a swing fulcrum with one upstream end and the other downstream end facing each other with the leading edge opposed. 29. The two break plates 28, 29 are configured to swing the two break plates 28, 29 up and down by the action of a cylinder 30 as a moving means installed on the moving tables 20, 21.

  The front and rear suction nozzles 14 and 14 are supported by the arms 31 that rise from the movable bases 20 and 21.

  5 and 6, the slider 34 provided on the lower surface of the slide base 33 is slidably engaged with the rail 32 in the front-rear direction, and the rail 23 is provided on the slide base 33, and the stationary motor 35 is provided. The male screw 36 driven by the reversible operation is screwed into the female screw 37 of the slide base 33.

  Then, it is possible to adjust the break position by the break bar 13 and the cutting lines 3 and 4 by operating the motor 35 as the mark is read by the camera.

  As shown in FIGS. 5, 10, and 11, a guide rail 40 that crosses the belt conveyor 11 is provided on the lower surface of the liquid crystal panel A on the front side of the head of the belt conveyor 11. A scribe cutter 43 that is lifted and lowered by a cylinder 42 as a lifting means on the combined slider 41 is provided, and a male screw 45 for reversible operation of the stationary motor 44 is screwed into a female screw 46 of the slider 41, thereby While the cutter 43 reciprocates, the cutter 43 is lifted by, for example, a cylinder 42 as an elevating means in accordance with the travel of the slider 41 in one direction, whereby the liquid crystal panel A has a liquid crystal on the lower surface of the TFT substrate 2 on the B surface. A cutting line 8 for dividing the panel A into the large panel a can be scribed.

  Further, a backup bar 48 that is lifted and lowered by a cylinder 47 as a lifting means is provided immediately above the cutter 43 and above the liquid crystal panel A.

  The mark of the scribe position by the cutter 43 is read by the camera, and the cutter 43 (as well as the backup bar 48) coincides with the scribe position accompanying this reading (for example, the position adjustment of the break bar 13 has the same configuration, etc.) May be adjusted).

  The backup bar 48 guides the ascending and descending by causing the slider 53 provided below the upper edge of the plate surface of the backup bar 48 to slidably engage with the vertical rail 52 provided on the portal frame 51.

  Further, in front of the cutter 43, there is provided a swing table C on which the liquid crystal panel A is slid on the front auxiliary table 54 from the belt conveyor 11 and receives the cargo.

  If the auxiliary table 54 is provided so as to be able to turn around the head pulley of the belt conveyor 11 (the turning function is not shown), it can be retracted in the descending direction.

  Below the swing table C is provided a moving table 55 in the front-rear direction in which the sliders 17 at both ends are slidably engaged with the rails 16. The moving table 55 has the same configuration as that of the portal frame 15. It is possible to adjust the movement in the front-rear direction by a male screw 57 that is driven by reversible operation of the motor 56 and a female screw 58 provided on both sides of the moving base 55 so that the male screw 57 is screwed.

  The cause of this movement adjustment is that a break position (to be described later) is read by a camera, and the position adjustment (break position) can be adjusted along with this reading.

  The swing table C is swung in the vertical direction by the action of, for example, a cylinder 59 as a lifting means installed on the movable table 55.

  Further, on both sides close to the lower backup bar of the swing table C, there are guide means having a lifting guide 61 that causes the swing table C to slide forward in accordance with the swing in the descending direction of the swing table C due to the action of the cylinder 59. D is provided.

  As shown in FIGS. 5, 6, and 11, the guide means D projects a rail material 62 downward from the lower surfaces of both head-side corners of the belt conveyor 11 of the swing table C, Are formed with an arc-shaped long hole 63 provided so as to face obliquely backward, and a rotor 64 that is supported by the moving base 55 and fitted into the long hole 63, and the upper half of the long hole 63 serves as a rising guide T, The lower half of the long hole 63 is a lowering guide S.

  Note that the frictional resistance is reduced by bringing the trochanter 65 supported at the end of the cylinder 59 in the protruding direction into contact with the lower surface of the swing table C.

  Further, the folded panel on the swing table C is paid out by the belt conveyor 66.

  As shown in FIG. 5, a plurality of parallel grooves 71 along the traveling direction of the belt conveyor 11 are provided on the upper surfaces of the break plates 28 and 29, and the inside of the grooves 71 (with suction hoses connected) is sucked. At the same time, by providing a number of through holes 72 in the belt of the belt conveyor 11, the liquid crystal panel A is sucked and held on the belt to prevent the liquid crystal panel A from slipping on the belt. Can be split.

Next, splitting using the splitting device having the above configuration will be described.
The liquid crystal panel A is supplied onto the belt conveyor 11 with the A side (CF substrate 1) facing upward (see FIG. 1).

  When the preceding cutting line 3 of the liquid crystal panel A reaches and stops immediately above the leading edges of the break plates 28 and 29 in the closed posture (shown in FIG. 8) at the opposite ends, both the break plates 28 are stretched by the cylinder 30. 29 rises as shown in FIG.

Then, as shown in FIG. 9 and FIG.
This splitting sequentially cuts the cutting line 3.

  When the broken liquid crystal panel A of the cutting line 3 is conveyed forward and stopped, the backup bar 48 is first lowered by the extending action of the cylinder 47, and the A surface (front surface) of the liquid crystal panel A is moved from the tip of the backup par 48. Hold down.

  Under this condition, the slider 41 is reciprocated by the reversible operation of the motor 44, and the cutter 43 is lifted by the extension action of the cylinder 42 in the forward direction, so that the cutting line 8 is formed on the lower surface of the B-side TFT substrate 2 (FIG. 13). (See (c) of).

  Of course, the cutter 43 is lifted and restored by the contraction action of the cylinder 42 when the slider 41 returns.

  Further, the backup bar 48 is raised and returned (as shown in FIG. 17) by the contraction action of the cylinder 47 when the liquid crystal panel A is transported.

  The backup bar 48 is lowered (as shown in FIG. 17) when it is split by a swing plate C described later.

  When the liquid crystal panel A fed forward stops (see FIG. 11), the swing table C having a horizontal posture as shown in FIG. The liquid crystal panel A also rises, and along this rise, the cutting line 8 is broken as shown in FIG.

  At this time, as the rotor 64 in the long hole 63 of the guide means D moves to the lowering guide S, the swing table C moves forward.

  Then, as shown in FIG. 13 (d), the contact of the electrodes is avoided by the floating of the surface facing the split edge, and as shown in FIG. 13 (e), the large liquid crystal panel A by the belt conveyor 66 is obtained. -1 (shown in FIG. 2) can eliminate the damage to the electrode due to contact avoidance.

  As shown in FIGS. 15, 16 and 17, if a break auxiliary bar 82 is provided on the outer side of the swing table C and the tip is directed obliquely rearward and upward due to the action of the cylinder 81 installed on the movable table 55, Sometimes, the lower end of the B surface of the liquid crystal panel A is supported by the protruding end surface of the break auxiliary bar 82, so that smooth splitting can be performed.

  The split large liquid crystal panel A is sent to the conveyor 66 from the swing table C returned to the fixed position, and is removed by a standby transfer machine (not shown) after the feeding.

Next, the folding with the B surface (TFT substrate 2) of the liquid crystal panel A on the upper side will be described with reference to FIG.
At this time, the cutting line 5 is pretreated on the lower A surface (lower surface of the CF substrate 1), and the cutting line 4 is pretreated on the upper B surface (TFT substrate 2).

  The liquid crystal panel A is supplied and conveyed on the belt conveyor 11, and the cutting line 5 accompanying this conveyance stops just below the break bar 13.

  At this time, due to the contraction action of the cylinder 26, the movable bases 20 and 21 are slid away from each other, and a gap is provided between the opposing ends of the break plates 28 and 29 as shown in FIG.

  Under this condition, the break bar 13 is lowered by the extending action of the cylinder 12, so that a downward pressing force acts on the B surface of the liquid crystal panel A, and the cutting line 5 is folded as shown in FIG. Divided.

  Then, the liquid crystal panel A is fed onto the swing table C, and then the tip of the backup bar 48 lowered by the extending action of the cylinder 47 is placed on the upper surface of the liquid crystal panel A (on the surface of the TFT substrate 2 on the B surface) as shown in FIG. ) Abut.

  Accordingly, by lowering the swing table C as shown in FIGS. 20 to 21 by operating the cylinder 59 as the lifting means, the cutting line 4 is broken (divided) as shown in FIG. Is done.

At this time, since the rotor 64 moves to the ascending guide 61 of the guide means D, the swinging table C that descends and tilts tends to move forward (as shown in FIG. 22). As shown in FIG. 23 (d), the large-size panel A-1 which is not contacted with the exposed electrodes due to the split edges separated by the splitting and is not contacted is paid out by the belt conveyor 66.
Therefore, the electrode exposed at the split edge is not damaged.

In addition, the large-sized liquid crystal panel A-1 which has been split is divided into small pieces (divided into single pieces) using the splitting device of the present invention.
At this time, naturally, the terminal can be broken intact.

  The splitting of the A side and the B side using the swing of the above-mentioned swing table C is all divided due to twisting, so that even a thin plate like a recent liquid crystal panel is very smooth and defective. Occurrence can be eliminated.

  In the splitting step, the lower surface is split (divided) by the break bar 13 with respect to the scribed substrate (1 and 2) on both the A and B sides.
