Detailed Description
Next, a first embodiment of the present invention will be described with reference to fig. 1 to 4.
In the present embodiment, the direction of arrow a in the drawings of fig. 1 and 2 is defined as the moving direction of the cutting device 1 (holding unit 4 described later) for the glass substrate G. In addition, the X direction and the Y direction in the drawings of fig. 3 and 4 are defined as the directions in which the scribing line L is formed on the upper surface of the glass substrate G. The X direction and the Y direction are orthogonal to each other.
first, the cutting apparatus 1 for the glass substrate G will be described with reference to fig. 1 and 2.
The cutting apparatus 1 for a glass substrate G is an apparatus for forming a scribing line L on the upper surface of the glass substrate G. The cutting device 1 for glass substrates G is provided with a platform 2, a moving part 3, a holding part 4, a scribing blade 5, a blow nozzle 6 for preventing rolling-in and a dust collecting part 7.
The stage 2 is a member on which the glass substrate G disposed on the protective sheet S can be placed. Preferably, the stage 2 is a conveyor capable of carrying the glass substrate G into and out of the cutting apparatus 1. The protective sheet S is a member for preventing damage to the glass substrate G. The protective sheet S is laid on the lower surface of the glass substrate G in a state of protruding from the peripheral edge portion of the glass substrate G.
The moving unit 3 is a member that moves the holding unit 4 in a predetermined direction. The moving unit 3 can move the holding unit 4 in the directions of arrow a and arrow B.
The holding section 4 is a member for holding the scribing blade 5, the entanglement preventing nozzle 6, and the dust collecting section 7. The holding portion 4 is provided in the moving portion 3. The dust collecting part 7 includes a dust collecting mouthpiece 8 and a suction nozzle 9. The dust collecting nozzle 8, the scribing blade 5, the suction nozzle 9, and the entanglement preventing nozzle 6 are arranged in this order from the rear side in the moving direction of the holding part 4. The order and the positions of the dust collecting nozzle 8, the scribing blade 5, the suction nozzle 9, and the entanglement preventing nozzle 6 are not particularly limited.
The holding portion 4 includes a pressure cylinder 10, a link mechanism 11, and a blade holder 12. The pressing cylinder 10 and the blade holder 12 are connected by a link mechanism 11. The blade holder 12 holds a scoring blade 5 at its lower end. The holding unit 4 is configured such that the pressing force of the pressing cylinder 10 is transmitted to the scribing blade 5 via the link mechanism 11 and the blade holder 12. The link mechanism 11 operates the scribing blade 5 in the up-down direction according to the reaction force received by the scribing blade 5 from the glass substrate G.
The scribing blade 5 is a member for forming a scribing line L on the upper surface of the glass substrate G. As the holding portion 4 moves, the scribing blade 5 moves in the X direction and the Y direction (see fig. 3 and 4) while pressing the glass substrate G, thereby forming the scribing line L in the X direction and the Y direction on the upper surface of the glass substrate G.
the entanglement preventing nozzle 6 is a member that blows air (compressed air) toward the outside of the peripheral edge portion of the protruding portion C protruding from the peripheral edge portion of the glass substrate G in the protective sheet S. The entanglement preventing mouthpiece 6 is disposed on the front side of the holding portion 4 in the moving direction of the holding portion 4 in the holding portion 4. The entrainment prevention nozzle 6 includes a rotation mechanism that rotates about a vertical portion thereof, and is capable of changing the direction of blowing air. The entanglement preventing nozzle 6 may blow air only when the scribing line L is formed on the upper surface of the glass substrate G, or may blow air all the time.
The dust collecting section 7 is a member that collects glass dust generated when the scribe line L is formed.
The dust collection nozzle 8 is a member that blows air (compressed air) toward the formed scribing line L. For example, the dust collecting mouthpiece 8 is formed of a SUS pipe. The dust collection blowing nozzle 8 blows compressed air toward the formed scribing line L, thereby scattering glass dust generated at the time of forming the scribing line L.
the suction nozzle 9 is a member that sucks the glass dust scattered by the air blown by the dust collection nozzle 8. For example, a venturi system is used as a suction system of the suction nozzle 9.
Next, a description will be given of a case where the scribe line L is formed on the upper surface of the glass substrate G, with reference to fig. 3 and 4.
The moving section 3 (see fig. 1 and 2) moves the scribing blade 5 in the Y direction to form a pair of scribing lines L parallel to each other. Next, the moving section 3 moves the scribing blade 5 in the X direction to form a pair of scribing lines L parallel to each other. While the scribing blade 5 forms the scribing line L, the suction nozzle 9 sucks the glass dust scattered by the air blown by the dust collecting nozzle 8. The entanglement preventing nozzle 6 is disposed on the front side in the moving direction of the holding portion 4, and therefore moves ahead of the scribing blade 5. The entanglement preventing nozzle 6 blows air to the protruding portion C protruding from the peripheral edge portion of the glass substrate G of the protective sheet S toward the outside of the peripheral edge portion while moving ahead of the scribing blade 5.
according to the cutting apparatus 1 for glass substrates G having such a configuration, the projecting portion C of the protective sheet S projecting from the peripheral edge portion of the glass substrate G is blown with air toward the outside of the peripheral edge portion, thereby preventing the protective sheet S from being bent toward the glass substrate G. Therefore, the scribing line L can be prevented from being incorrectly formed due to the rolling-in of the protective sheet S.
Further, according to the cutting apparatus 1 for glass substrates G, the protective sheet S is prevented from being bent toward the glass substrate G before the scribing line L is formed on the upper surface of the glass substrate G. Therefore, the scribing line L can be prevented from being incorrectly formed due to the rolling-in of the protective sheet S.
Further, according to the cutting apparatus 1 for glass substrates G, adhesion of glass dust generated at the time of forming the scribing line L to the glass substrate G is prevented. Therefore, the formation of scratches on the surface of the glass substrate G due to the glass dust can be prevented, and the quality of the glass substrate G finally produced as a product can be improved.
Next, a cutting apparatus 1 for a glass substrate G according to a second embodiment will be described with reference to fig. 5 and 6. Hereinafter, the same members are referred to by the names and reference numerals used in the description of the cutting apparatus 1 for glass substrates G of the first embodiment. Here, a description will be given mainly of a portion of the cutting apparatus 1 different from the glass substrate G of the first embodiment. In the present embodiment, the direction of arrow B in the drawings of fig. 1 and 2 is defined as the moving direction of the holding portion 4, and the description will be given.
The moving section 3 (see fig. 1 and 2) moves the scribing blade 5 in the Y direction to form a pair of scribing lines L parallel to each other. Next, the moving section 3 moves the scribing blade 5 in the X direction to form a pair of scribing lines L parallel to each other. Since the entanglement preventing nozzle 6 is disposed on the rear side in the moving direction of the holding part 4, the entanglement preventing nozzle 6 blows air toward the outside of the peripheral edge part of the glass substrate G after the glass dust is collected by the dust collecting nozzle 8 and the suction nozzle 9. Therefore, after the scribing line L in the Y direction is formed, the protective sheet S is prevented from being bent toward the glass substrate G. Therefore, when the scribing line L in the X direction is formed by the scribing blade 5, the formation of the scribing line L can be started in a state where the protective sheet S is not bent toward the glass substrate G.
According to the cutting apparatus 1 for glass substrates G having such a configuration, the protective sheet S is prevented from being bent toward the glass substrate G after the scribing line L is formed on the upper surface of the glass substrate G. Therefore, when one scribing line L is formed on the upper surface of the glass substrate G and then another scribing line L is formed, the formation of the scribing line L can be started in a state where the protective sheet S is not bent toward the glass substrate G. In particular, there is a tendency that: when the stage 2 is a conveyor and the glass substrate G is conveyed in the X direction, the protruding portion C at the front end and the protruding portion C at the rear end in the X direction are bent toward the glass substrate G when the glass substrate G is stationary on the stage 2. In this case, first, the scribing line L is formed in the Y direction, and thus the entrainment-preventing blowing nozzle 6 blows air toward the outside of the peripheral edge portion of the glass substrate G, and the bending of the overhang portion C at the front end portion and the overhang portion C at the rear end portion to the glass substrate can be corrected. Thus, the scribing blade 5 can start the formation of the scribing line L in the X direction without the bending toward the glass substrate C side in the protruding portion C of the front end portion and the protruding portion C of the rear end portion. Therefore, the improper formation of the scribing line L due to the entanglement of the protective sheet S can be suppressed.
In the cutting apparatus 1 for the glass substrate G, the entrainment prevention nozzle 6 may be disposed in the holding portion 4 on both the front side and the rear side in the moving direction of the holding portion 4. With this configuration, the protective sheet S is more reliably prevented from being bent toward the glass substrate G. Therefore, the scribing line L can be more reliably prevented from being incorrectly formed due to the entanglement of the protective sheet S.
In the above-described embodiment, the cutting device 1 has the dust collecting section 7, but the dust collecting section 7 is not essential.
The above-described embodiments are merely representative embodiments, and various modifications can be made without departing from the gist of one embodiment. It is needless to say that the present invention can be implemented in various forms, and the scope of the present invention is shown by the description of the scope of the claims, and includes all modifications equivalent in meaning and scope to the description of the scope of the claims.
