Description

[0001] CUTTING APPARATUS OF PANEL [0002]
This invention relates to a device for cutting (dividing) a liquid crystal panel (liquid crystal panel).
As a conventional method for obtaining a panel of a product size while sequentially cutting out a large-sized liquid crystal panel, various methods are already known (see, for example, Patent Documents 1, 2 and 3).
: Japanese Patent No. 3759450 : Japanese Patent No. 3969992 : Japanese Patent No. 5256554
However, in Patent Document 1, the cutting for dividing is a collision method using a bar material or a roll.
The cutting in Patent Document 2 is a collision type by a roll as a cutting member.
The cutting of Patent Document 3 is a collision type by a folding bar.
When the above-described cutting method is employed in recent panel cutting, various problems arise.
That is, the recent liquid crystal panel has a very fine structure (in the case of making each substrate and the electrode film (electrode film) laminated so thin that their weight is lightened and the cost is reduced) Cracks penetrate into portions other than the cut, which causes defective products. In addition, because the internal wiring is fine, a broken wire is generated due to an impact of impact or the like, resulting in a defective product. It is necessary to remove the attached cullet as the cullet is scattered.
Particularly, the terminal material is removed in accordance with cutting to expose the terminal (the inner surface of the terminal portion is exposed) exposing the electrode (electrode) to the edge of the panel. However, There has been a problem that when the end member which is a material (waste material) is slide-moved while being in contact with the exposed terminal surface, the terminal surface is damaged (broken) and becomes defective.
In addition, in the case of cutting (dividing) the side edge (to remove the rim) of the liquid crystal panel, if the above-mentioned collision system is employed, cracks penetrate into portions other than the cut due to collision, Further, a problem such as disconnection occurs due to the impact of the collision.
Therefore, this invention is to provide a liquid crystal panel cutting apparatus which solves the above problem.
In order to solve the above-mentioned problems, the invention is directed to a belt conveyor for conveying a liquid crystal panel, a brake bar provided on the belt conveyor so as to be raised and lowered by the elevating means at a cutting position on the front upper side of the carrier- And a moving belt arranged on the lower side of the carrier belt of the belt conveyor below the brake bar and moving toward and away from the moving belt by the moving means, A brake plate provided on the belt conveyor so as to support opposite ends thereof to rotate in opposite directions and to raise and lower a front end of each of the opposite ends thereof by the lifting means; To Sudan A cutter provided so as to scribe a cut line on the lower surface of the liquid crystal panel by a lifting means as a traveling body installed to run by the cutter, A swing table provided so as to store the liquid crystal panel in front of the cutter, a lifting and lowering means provided to swing the swing table in the vertical direction, And guiding means having a rising guide provided so that the swing table slides forward in accordance with the swinging direction of the swing table by the back-and-forth lifting means.
And the guide means is formed by combining with a descending guide continuously extending downwardly from the ascending guide so that the swing table slides forward in accordance with the swing of the swing table in the ascending direction by the ascending / descending means.
A first accommodating means and a second accommodating means provided on the front and rear sides for accommodating the supplied liquid crystal panel; a supporting member provided to stand on both sides between the first accommodating means and the second accommodating means; A slider coupled to the rail and a slider coupled to the rail to slide the slider in the forward and backward directions on the upper side of both rotors so as to pivotally support the middle of both ends of the slider A pair of sliders slidably coupled to a lower rail of the rotating body and a rail extending in the longitudinal direction of the rotating body, And the two grip pawls Lifting means provided to and be employed a configuration consisting of a rotating action of the rotating means is provided to rotate in the forward and backward directions.
A first accommodating means and second accommodating means provided on the front and rear sides for accommodating the supplied liquid crystal panel; a supporting member provided so as to stand on both sides between the first accommodating means and the second accommodating means; Forward and backward shifting means provided for shifting the upper and lower bases of the upper and lower bases, respectively, in the forward and backward directions; And a raising and lowering means provided so as to raise and lower both of the pressure dividing pawls.
As described above, according to the panel cutting apparatus of this invention, the liquid crystal panel is supplied and transported on the belt conveyor such that the A side (CF side) is on the upper side.
When the cutting line where the pretreatment of the A surface is stopped immediately above the end portions of the front and rear brake plates is stopped, the opposite end portions of the both brake plates are raised by the action of the lifting means, The cutting line is broken.
When the liquid crystal panel conveyed forward is subsequently stopped, the traveling body is caused to travel by the reciprocating traveling means after the backup bar is lowered by the elevating means first, and the cutter is lowered by the elevating means in accordance with the advancing travel of the traveling body And a cut line is scribed on the B side by the cutter.
Thereafter, the swing table is raised by the action of the traveling means.
The swing table swings up in the ascending direction while the front end of the backup bar is positioned as a point and the swing table rises as the A side of the liquid crystal panel is continuously pressed by the falling backup bar at this time And is extruded in the downstream direction by the descent guide of the guide means.
Therefore, it is possible to avoid the contact of the cutting edge of the liquid crystal panel in the cut portion of the panel (the portion that is divided between the downstream side and the upstream side of the backup bar) and to prevent the interference of the terminal portions One cutting (CF surface can be divided by no touch method).
And the liquid crystal panel is supplied onto the belt conveyor so that the B side (TFT side) is on the upper side, and the liquid crystal panel is transported.
On the other hand, the brake plates on the front and rear sides slide the both moving belts in the opposite directions by the action of the moving means so that a gap is formed between the opposite end portions of the both brake plates.
In this situation, when the cutting line after the pretreatment of the lower side A is stopped between the opposite end portions of the brake plate, the brake bar is lowered by the elevating means to break the cutting line on the A side, And sucked by the suction nozzle to be recovered.
After the backup bar is lowered by the lifting means, the swing table is lowered by the lifting means.
In this case, since the B-side of the liquid crystal panel is continuously pressurized by the backup bar which is being lowered at this time, the swing table is cut (divided) while the front end of the backup bar becomes a point and the swing table swinging in the downward direction And is extruded forward by the guide means of the guide means.
Therefore, it is possible to avoid the contact of the cut end of the liquid crystal panel at the cut portion of the panel (the portion divided between the downstream side and the upstream side of the backup bar), and the interference of the terminal portions It is possible to perform cutting (division) so as not to exist.
In other words, there is a peculiar effect of preventing generation of defective products without damaging the terminal surface with very smooth cutting.
In addition, since the cutting by the swing table is performed by twisting, there is a peculiar effect that various problems such as a collision with a large impact which is already known can be eliminated.
Further, after the edges of the liquid crystal panel are held by the upper and lower grip pawls, the edges of the edges of the liquid crystal panel are cut while the gripping pawls are moved while being inclined while rotating the rotating body by the rotating action means. Method.
Therefore, there is a peculiar effect of eliminating various disadvantages such as collision.
In addition, there is a peculiar effect of eliminating various disadvantages such as collision because the edge of the liquid crystal panel is continuously pressed by the upper and lower pressure dividing pawls and ironing cutting is performed. In addition, The lower base can be moved back and forth so that the cutting position can be freely changed.
In addition to the above, the front edge and the rear edge of the liquid crystal panel can also be cut in one direction (one direction).

Next, cutting using the above-described cutting apparatus will be described.
The liquid crystal panel A is supplied with the A side (CF substrate 1) facing upward on the belt conveyor 11 (see Fig. 1).
When the preceding cutting line 3 of the liquid crystal panel A reaches and stops just above the leading edge of the break plates 28 and 29 whose opposite ends are closed (shown in Fig. 8) The two brake plates 28 and 29 are lifted up as shown in Fig.
In this manner, cutting (division) is performed as shown in Figs. 9 and 13 (B).
This cutting successively divides the cutting line (3).
When the liquid crystal panel A in which the cutting of the cutting line 3 is completed is transported forward and stopped, the backup bar 48 is lowered by the extension action of the cylinder 47, Press the A side (surface) of the panel A.
Under this circumstance, when the slider 41 reciprocates by the reversible operation of the motor 44 and the first running (running from the left to the right in Fig. 10) is performed, by the extension action of the cylinder 42, The scribing line 8 is scribed on the lower surface of the TFT substrate 2 which is the B side (see FIG. 13 (C)).
Of course, the cutter 43 is lowered and returned by the contracting action (contracting action) of the cylinder 42 when the slider 41 performs the second travel (running from the right side to the left side in Fig. 10).
Further, when the liquid crystal panel A is transported, the backup bar 48 is raised and returned by the contracting action of the cylinder 47.
In addition, the backup bar 48 is lowered (as shown in Fig. 17) in cutting by the swing table C described later.
When the forward liquid-crystal panel A is stopped (see Fig. 11), the swing table C in the horizontal posture as shown in Fig. 14 is swung upward by the extension action of the cylinder 59, The liquid crystal panel A on the table C also rises, and the cutting line 8 is cut as shown in Fig.

13 (D), the contact of the electrode (electrode) is avoided by floating of the opposing face of the cut edge, and as shown in Fig. 13 (E), the belt conveyor 66, It is possible to prevent the electrode from being damaged due to contact avoidance at the time of discharging the first liquid crystal panel A-1 (shown in Fig. 2).
As shown in Figs. 15, 16, and 17, a brake auxiliary bar (for example, refer to Fig. 15) is provided outside the swing table C, the lower side of the liquid crystal panel A on the side of the projecting end of the brake assist bar 82 can be pivoted when the brake is applied.
The cut primary liquid crystal panel A-1 is sent to the conveyor 66 from above the swing table C returned to the predetermined position. After the feeding, the standby liquid feeder Omitted).
Next, a description will be given of a cutting operation in which the B side (TFT substrate 2) of the liquid crystal panel A is turned upside, with reference to Fig.
At this time, the cutting line 5 is pretreated on the lower side A (lower surface of the CF substrate 1) and the cutting line 4 is pretreated on the upper side B side (TFT substrate 2).
The liquid crystal panel A is fed onto the belt conveyor 11 and is conveyed. The cutting line 5 following the conveyance is stopped just below the break bar 13.
At this time, the movable bands 20 and 21 are slid by the contraction action of the cylinder 26 so that gaps are formed between the opposite end portions of the both brake plates 28 and 29 as shown in Fig.
Under this circumstance, the brake bar 13 is lowered by the expansion action of the cylinder as the elevating means 12, so that a downward pressing force acts on the B face of the liquid crystal panel A, as shown in FIG. 23B The cutting line 5 is cut.
20, the liquid crystal panel A is transported onto the swing table C and then the tip of the backup bar 48 descended by the extension action of the cylinder 47 is moved to the upper surface of the liquid crystal panel A (The surface of the TFT substrate 2 on the B side).
The cutting line 4 is cut (divided) as shown in Fig. 23 (C) by operating the cylinder 59 as the elevating means and lowering the swing table C as shown in Fig. 20 to Fig.
At this time, because the swing table C is inclined forward (as shown in Fig. 22) to be lowered because the rotor 64 is moved by the raising guide T of the guide means D, As shown in Fig. 23 (D), the first liquid crystal panel A-1 cut in this noncontact state does not come into contact with the exposed electrodes due to the cutting edges separated by the cutting as shown in Fig. 23 (C) And is drawn out to the belt conveyor 66.
Therefore, the electrodes exposed at the cutting and breaking edges are not damaged.
Further, the cut primary liquid crystal panel (A-1) is cut into a secondary part (divided into individual items) which is the product size by using the cutting device of this invention.
At this time, it is of course possible to carry out cutting without damaging the terminal.
Since cutting of the A-plane and the B-plane using swing of the swing table C is a division accompanied by twisting, even if it is thinned like a recent liquid crystal panel, .
(1) and (2), which are scribed together with the A-side and B-side in the cutting step, are cut (divided) by the break bar 13.
