A cutting device for the object and a cutter device for the cutting device of the rectangular plate. [Embodiment] Hereinafter, a glass cutter according to an embodiment of the present invention will be described with reference to the drawings. [Outline of Glass Cutting Machine ίο] Fig. 8 is an explanatory view of a general manufacturing procedure of a glass plate. As shown in Fig. 8, a glass plate for a flat panel display (for example, a glass plate for a liquid crystal display (LCD), a glass plate for a PDP (plasma display panel), and an organic EL (Electro Luminescence electroluminescent) display or glass plate for organic el planar light source) is generally manufactured by the following steps, etc. · Cutting step P1, and manufacturing 162778.doc 201245065 into a special thickness of the glass plate to a specific size; In the chamfering step p2, chamfering the end surface of the cut glass plate with grinding stone or grinding stone; cleaning 'drying step P3, cleaning the chamfered glass plate' to dry; and measuring step P4 The shape of the glass plate after the washing and drying is measured. The glass cutter 10 is provided in the cutting step ρι in the above step. The figure is used to illustrate the moving direction of the cutter device 12. As shown in FIG. ,, the glass plate 20 of the object to be cut is a rectangular glass plate (for example, the number of lengths m×the number of widths m×the thickness is about several mm), and is conveyed by a known conveying mechanism (not shown) and clamped. It is placed on the platform 22 of the glass cutter 10 (see Fig. 2(a)). Further, the preferred size of the tangential glass plate 2 is processed by the glass cutter 10 to have a thickness of 0.1 to 3.0 mm. FIGS. 2(a) to 2(d) are used to illustrate the cutter support arm 12f. The map of the action. As shown in Figs. 2(a) to 2(d), the glass cutter 10 is configured such that the cutter 12h positioned at a predetermined cutting depth h is parallel to the surface of the glass sheet 20 by using a well-known lifting mechanism or the like. That is, it moves in the direction of the arrow (see FIG. 2(a)), and abuts against one end surface 20a of the glass plate 20 (see FIG. 2(b)). Further, the cutter 12h is moved in the state of being pressed against the glass sheet 20 and further moved toward the other end surface 20b on the opposite side of the glass sheet 2 (see FIGS. 2(c) and 2(d)), and is placed on the glass. The surface of the plate 20 is cut into a flaw (tangent line) which is the starting point of the cut. [Configuration of Glass Cutting Machine 10] Fig. 3 is a system configuration diagram of the glass cutting machine 10. As shown in FIGS. 1 and 3, the glass cutter 10 includes four cutter devices 12χ丨 to 12γ2 and four cutter drive mechanisms 14X丨 to 14丫2 disposed corresponding to four sides of the glass plate 20, and further Package 162778.doc •10- 201245065 includes control device 16, memory device 18, etc. for controlling such. [Configuration of Cutter Device 12Χ丨~12丫2] A configuration diagram of the circular 4-system cutter device 12. As shown in Fig. 4, each of the cutter devices 12X1 to 12γ2 includes a head main body 12a, and the head main body 12a is formed with a vertical hole 12a2 as a cylinder extending from the lower surface 12al in the vertical direction (i.e., vertically above). The air passage 12a3 of the vertical hole 12a2. A piston 12c is disposed in the vertical hole 12a2 via a sliding sleeve. The working gas source 12e is connected to the air passage 12a3 via the solenoid valve 12d. When the control device 16 controls the opening of the electromagnetic valve I2d, the air of the predetermined pressure is supplied from the air source 12e through the air passage 12a3 to the vertical hole 12a2, and the air is vertically lowered downward by the action of the air. The piston 12c is pressed, and the tip end (the supported roller 12ci) abuts against the cutter support arm 12f', and the cutter support arm 12f is biased to swing downward (see Fig. 2(b)). Thereby, the cutter 12h is pressed against the surface of the glass plate 20. The cutter support arm 12f is disposed vertically below the piston 12c so as to be in contact with the piston 12c (the roller i2cl supported at the tip end thereof) which is pressed downward by the action of the air supplied to the vertical hole 12a2. The shaft 12fl on the proximal end side of the cutter support arm 12f is supported by a bearing 12a4 fixed to the head body 12a. In other words, the cutter supporting arm 12f is swingably supported by the head main body 12a in the slanting direction about the shaft 12f 1 on the proximal end side. The shaft 12gl of the cutter holder 12g is supported by a bearing 12f2 fixed to the cutter support arm 12f. That is, the cutter holder 12g is rotatably supported by the cutter support arm I62778.doc 201245065 1 2f centering on the shaft 12gl in a direction parallel to the surface of the glass sheet 20. The effect shown below can be obtained by rotatably supporting the cutter holder 1 2g. When the shaft 12gl of the cutter holder 12g is attached to the bearing 12f2, even if the traveling direction of the cutter 12h does not coincide with the traveling direction of the cutter device 12, the cutter 12h is brought into contact with the surface of the glass sheet 20 to cut. When the knife device 12 travels, the traveling direction of the cutter I2h can be corrected to the same direction as the traveling direction of the cutter device 12. The cutter 12h is, for example, a disc-shaped cutter wheel (or a cutting blade), and is supported by the cutter holder 12g in a state in which at least a part thereof protrudes downward from the lower end of the cutter holder 12g. The protruding portion is pressed against the surface of the glass sheet 20 (refer to Fig. 2(b)). The cutter support arm 12f swings downward from the shaft 12 fl due to its own weight, and abuts against the joint i2i fixed to the head main body 12a (see Fig. 2(a)). By this, the contact 12i is electrically connected to the cutter support arm 12f, and the swing of the cutter support arm 12f to the downward direction is restricted. The head main body 12a, the cutter support arm 12f, and the contact 12i are each made of a conductive material such as metal. Further, the head main body 12a is electrically connected to the cutter supporting arm I2f. However, since the contact 12i is surrounded by the insulating material 12il such as synthetic resin, it is electrically insulated from the head main body 12a. [Configuration of the cutter drive mechanism 14χ1, 12χ2] The devices 12Χ1 and 12Χ2 are slidably and movably attached to, for example, two guide structures (not shown) extending in the X direction (see FIG. 1) and arranged at a fixed interval. The cutter device 12 γ i, 12 γ 2 is, for example, two guide members (not shown) that are slidably and movably disposed in the Y direction (see FIG. 1 ) and disposed at a fixed interval. 162778.doc 12 201245065

During this period, the cutter support arm i2f of each of the cutter devices 12A to 12YS abuts on the contact 12i due to its own weight (see Fig. 2(a)). When the cutters l2h of the respective cutter devices 12χ, 12χ2 moving in the X direction abut against one of the end faces 20a and 20b of the glass plate 20, the cutter support arms 12f of the respective cutter devices 12X1 and 12xz are thereby The glass plate 2 is pushed up relative to each other and swings vertically upward around the shaft 12fl. Thereby, the cutters 12h of the cutter units 12X1 and 12X2 reach the surface of the glass sheet 20 from the one end faces 20a and 20b of the glass sheet 20 without receiving the load of the piston 12c (refer to Fig. 2(b)). At the same time, the cutter support arm i2f is released from the contact point i2i. Similarly, when the cutters 12h of the respective cutter devices 丨2γι and 丨2γ2 moving in the γ direction abut against one of the end faces 20c and 20d of the glass plate 2, the cutter supports of the respective cutter devices 12Y1 and 12Y2 The arm I2f is relatively pushed up by the abutting glass plate 2〇, and is swung vertically upward around the shaft 12fl. Thereby, the cutters 12h of the respective cutter devices 12Y1, 12Y2 reach the surface of the glass plate 2 from the one end faces 20a, 20b of the glass plate 20 without receiving the load of the piston i2c (refer to Fig. 2 (b)) » At the same time, the abutment of the cutter support arm i2f and the contact i2i is released. When the cutter support arm l2f of each cutter device ΐ2χΐ to 12γ2 is abutted against the contact H, the control device 16 detects that the power supply state between the cutter arm 12 • and the contact 12i is "non- Power on" (steps S12, S14: Yes). 162778.doc -15- 201245065 When the control device 16 detects that the energization state between the cutter support arm i2f and the contact I2i is "non-energized" (step S14: YES), the air source 12e passes through the air passage. The 12a3 controls the electromagnetic valve 12d so as to supply the air of a predetermined pressure to the vertical hole 12a2 (step S16). When air is supplied to the vertical hole 12a2, the piston i2c is pressed downward by the action of the air, and the tip end (the supported roller 12cl) abuts against the cutter support arm 12f. The blade support arm 2f applies a force to swing downward (see FIG. 2(b)). » Thereby, the cutter i2h is pressed against the surface of the glass plate 20. That is, the cutting blade 12h is given a cutting pressure. Each of the cutter devices 12Χ1 and 12χζ slides in the X direction while being cut by the slit extending in the X direction while the cutter 12h is pressed against the surface of the glass plate 20 (see FIGS. 2(b) and 2(c)). . In the same manner, in the state in which the cutters i2h are pressed against the surface of the glass plate 20, the respective cutter devices 12γ1 and 12γ2 slide in the Y direction while being cut into the flaw extending in the γ direction (see FIGS. 2(b) and 2( c)). Next, the control device 16 determines whether or not the cutting operation is completed (step S18). For example, the control device 16 determines whether each of the cutter devices 12 χ丨 12 12 γ 2 has moved to the position of the 曰 7 (or determines whether each of the cutter devices 12 〜 12 12 γ 2 has moved by a predetermined distance) 'to determine the movement to the command position (or When it is determined that the movement has a predetermined distance, it is determined that the cutting operation is completed. Alternatively, it is also possible to determine the end of the cutting operation in the case where the cutter supporting arms 12f are vertically lowered when the respective cutter devices 12x1 to 12γ2 (the cutter 12h) reach the other end faces of the glass sheets 20. The square swings and abuts on the contact 12 (refer to FIG. 2(d)), so that the energization state between the seven-knife support 2f and the contact (2) of 162778.doc.16-201245065 is detected as "energization". When it is determined that the cutting operation is completed (step s8: YES), the control device 16 performs control so that the electromagnetic valve 12d is closed (step S2). The processing is ended by the above steps. As described above, according to the present embodiment (operation example 1), the cutter 12h that moves in the direction parallel to the surface of the glass sheet 20 (X direction, γ direction) abuts against one end face 2 of the glass sheet 20 In the case of a and 20c, the cutter support arm 12f is relatively pushed up by the action of the abutting glass plate 2, and is swung vertically upward around the shaft 12' on the base end side. Thereby, the cutter 12h does not receive the load of the piston 12C, and reaches the surface of the glass plate 2 from the side faces 2〇a, 20c of the glass plate 2〇. Thereby, the impact when the cutter i2h abuts against one of the end faces 20a, 20c of the glass sheet 20 is moderated. Further, when it is detected that the cutter 12h reaches the surface of the glass sheet 20 (that is, when the energization state between the cutter support arm 12f and the contact 12i is detected as "non-energized"), the first use is utilized. The action of the air is pressed by the action of the piston l2c which is pressed downward to the lower side, and the cutter 12h is pressed against the surface of the glass plate 20 (that is, the cutting pressure is given). As described above, according to the present embodiment (operation example 1), when the force directed upward is applied, since the cutter 12h is supported so as to move, compared with the case where the cutter does not move, The impact of the cutter 12h abutting against one end face of the glass plate 20 can be alleviated. Thereby, it is possible to prevent (or reduce) the glass cutter 1 that can cause cracks or defects of the glass sheet 20 due to the cutter 12h abutting against one end surface of the glass sheet 20. [Operation Example 2 of Glass Cutter 10] 162778.doc 201245065 The operation example 2 of the glass cutter 10 having the above configuration will be described with reference to Fig. 6 . Fig. 6 is a flow chart for explaining the operation example 2 of the glass cutter. The following processing is mainly realized by the control device 16 executing a specific program read into the memory device 18. In the following processing, the glass plate 20 of the cut object is pre-positioned on the platform 22. First, the control device 16 uses a well-known lifting mechanism to cut the knife! 2h is positioned at a predetermined cutting depth. Referring to FIG. 2(a))e, at the same time, each servo motor is controlled such that each cutter device 12x1 to 12Y2 (the cutter 12h) moves from the origin position to the command position ( Step S3)). Each servo motor rotates the ball screw in accordance with the control rotation from the control unit 16. Thereby, each of the cutter devices 12X1 and 12X2 slides in the X direction (the direction opposite to each other, see Fig. 1) from the origin position along the guide member extending in the X direction. Similarly, each of the cutter devices 12γ and 12γ2 slides in the γ direction (the direction opposite to each other. See Fig. 1) from the origin position along the guide member extending in the x direction. During this period, the cutter supporting arm 12f of each of the cutter devices 12χ1 to 12γ2 abuts against the contact I2i due to its own weight (see Fig. 2(a)). When the cutters m of the respective cutter devices 12χ丨, 12χ2 moving in the X direction abut against one of the end faces 20a and 20b of the glass plate 20, the cutter support arms 12f of the respective cutter devices 12χ, 12xz are The abutting glass plate 2 is relatively pushed up and swings upward from the axis 12fl. Thereby, the cutters 12h of the cutter units 12X1, 12X2 reach the surface of the glass sheet 2 from the one end faces 20a and 20b of the glass sheet 20 without receiving the load of the piston i2c (refer to Fig. 2(b)). At the same time, the tool holder arm i2f and the contact point I2i are released. I62778.doc • 18 · 201245065. Similarly, when the cutters 12h of the respective cutter devices 12γ丨 and 12γ2 moving in the γ direction abut against one end faces 2〇c and 20d of the glass plate 20, the cutter supports of the respective cutter devices 12Y1 and 12Y2 The arm 12f is relatively pushed up by the abutting glass plate 2, and is swung vertically upward around the shaft 12A. Thereby, the cutters i2h of the respective cutter devices 12Y1 and 12Y2 reach the surface of the glass sheet 20 from the side faces 2〇a and 20b of the glass sheet 20 without receiving the load of the piston 12c (see Fig. 2(b)). At the same time, the abutment of the cutter support arm 12f and the contact 12i is released. When the cutter support arm i2f of each of the cutter devices 12X1 to 12Y2 is released from contact with the contact point i2i, the control device 16 detects that the power supply state between the cutter support arm 12 and the contact 12 is "non- Power on" (steps S32, S34: YES). At the same time, the control device 16 detects the position of the cutter I2h of each of the cutter devices 12χ12 to 12γ2 at this time point (this position is obtained, for example, from the control device 16) as the position of one of the end faces 20a to 20d of the glass plate 20 (step S36). And the control device 16 separates the positions of one of the end faces 20a to 20d of the glass plate 20 to be determined with a predetermined setting range (for example, an end face of a normal glass plate which is previously stored in the memory device 18 without cracks) The position of the soil is in the range of millimeters, and the comparison is made to determine the crack of the glass plate 2 (step S38). For example, if the position of one end surface 20a to 20d of the glass plate 20 to be inspected is outside the predetermined setting range, it is determined that there is a crack in the end surface 2〇a to 2〇d of the glass plate 20 to be detected ( Step S38: No), the situation is notified by displaying an alarm or the like (step S40). 162778.doc • 19- 201245065 On the other hand, if the position of one of the end faces 20a to 20d of the detected glass plate 2 is within a predetermined setting range, the control device 16 determines one end face of the detected glass plate 20. There is no crack in 20a to 2 0d (step S38: YES). When it is determined that there is no crack in one of the end faces 20a to 20d of the glass sheet 20 (YES in step S38), the control device 16 controls the air supplied from the air source 122 to the vertical hole 12a2 via the air passage 12a3 to the predetermined pressure. The solenoid valve 12d (step S42). When air is supplied to the vertical hole 12a2, the piston 12c is pressed downward by the action of the air, and the tip end (the roller 12c1 supported at the tip end) abuts against the cutter support arm 12f. The cutter support arm 12f applies a force to swing downward (see FIG. 2(b)). Thereby, the cutter 12h is pressed against the surface of the glass plate 20. That is, the cutting blade 12h is given a cutting pressure. Each of the cutter devices 12x and 12XS slides in the X direction while being cut into the surface of the glass plate 20 while the cutter i2h is pressed against the surface of the glass plate 20 (see FIGS. 2(b) and 2(c). ). In the same manner, each of the cutter devices 12yi and 12Y2 slides in the Y direction while being cut into the flaw extending in the γ direction while the cutter 12h is pressed against the surface of the glass plate 20 (see FIGS. 2(b) and 2( c)) The person's control device 16 determines whether or not the cutting operation is completed (step S44). / If the control device 16 determines whether each of the cutters is 12x wide 12Y2 is moved to the position (or determines whether each of the cutter devices 12X1 to 12Y2 is moved by a predetermined distance) 'in the case of determining to move to the command position (or When it is determined that the movement has a predetermined distance, the determination cut operation ends. Control device 1 < i, !>· When it is determined that the cutting operation is completed (step S44: YES) 162778.doc • 20-201245065 When the electromagnetic valve 12d is closed, control is performed (step S46). The processing is ended by the above steps. As described above, according to the present embodiment (operation example 2), the cutter 12h that moves in the direction parallel to the surface of the glass sheet 20 (X direction, γ direction) abuts against one end face 2 of the glass sheet 20 In the case of a and 20c, the cutter supporting arm 12f is relatively pushed up by the action of the abutting glass plate 2, and is swung upward from the ship 12 Π centered on the base end side axis 12Π. By this, the cutter 12h does not receive the load of the piston i2c and reaches the surface of the glass sheet 2 from the side faces 20a, 20c of the glass sheet 2〇. Thereby, the impact of the cutter i2h abutting against one of the end faces 2〇a, 20c of the glass plate 20 is further suppressed, and the case where the cutter 12h reaches the surface of the glass plate 20 is detected (ie, the cutter support is detected) When the energization state between the arm 12f and the contact 12i is "non-energized", first, the cutter i2h is pressed against the glass by the action of the piston 12c which is pressed downward by the action of the air. The surface of the plate 2 (ie, the cutting pressure). As described above, according to the present embodiment (operation example 2), it is possible to alleviate the contact end of the cutter 12h against the glass plate 20 as compared with the case where the cutter does not move vertically (or hardly moves) upward. The impact at 20a, 20c, thereby correspondingly preventing (or reducing) the glass cutter 10 which is cracked or missing due to the cutter 12h abutting against one of the end faces 20a, 20c of the glass sheet 20. Further, it is possible to realize a glass cutter 10» capable of detecting whether or not one end surface 2〇a, 20c of the glass sheet 2 is cracked. [Modification of the operation example 2] Next, a modification of the operation example 2 will be described. 162778.doc -21 - 201245065 The processing shown in Fig. 7 (S48 to S56) can also be performed instead of S44 to S46 in Fig. 6. When each of the cutter devices 12Χ1 to 12Y2 (the cutter 12h) reaches the other side of the glass plate 2', the cutter support arm 12f swings downward and falls against the contact 12i (refer to Fig. 2(d)) » In this case, the control device 16 detects that the energization state between the cutter support arm 2f and the contact 12i is "energized" (step S4g: at the same time) the control device 16 detects each of the cutter devices at this point in time. The position of the cutter 12h of 12χι 1212γ2 (this position is obtained, for example, from the control device 16) is the position of the other end faces 20a-20d of the glass plate 2 (step S50). Moreover, the control device 16 detects the The positions of the other end faces 20a to 20d of the glass plate 2 are respectively performed in a predetermined setting range (for example, a range of a few millimeters in the position of the end face of the normal glass plate which is not cracked in the sigma device 18). For comparison, the crack determination of the glass plate 2 is performed (step S38). For example, the control device 16 determines that the position of the other end faces 20a to 20d of the detected glass plate 2 is outside a predetermined setting range. The other end face of the glass plate 20 is detected 2〇a 2〇(1 There is a crack (step S52: NO), and the situation is notified by displaying an alarm or the like (step S54). On the other hand, the control device 16 is the other end faces 20a to 20d of the glass plate 20 to be inspected. When the position is within a predetermined setting range, it is determined that the other end faces 2〇a to 2〇d of the detected glass sheet 20 are free from cracks (step S52: YES) and control is performed by closing the electromagnetic valve 12d (step S56) The processing is terminated by the above-described steps. 162778.doc • 22· 201245065 As described above, according to the present modification (the modification of the operation example 2), it is possible to prevent (or reduce) the contact with the cutter 12h. a crack or a defect of the glass plate 2 caused by one end surface 20a 20c of the glass plate 20, and a glass cutter capable of inspecting whether the other end faces 2〇b, 20d of the glass plate 20 are cracked 10° Next, In the above-described embodiment, the piston 12c that is pressed downward by the action of the air is used as a cutting pressure applying mechanism that applies a force to the cutter support arm 12f to swing downward. Example is explained However, the present invention is not limited to this. For example, a solenoid valve and other mechanisms may be used as the cutting pressure applying mechanism. Thus, there is no need to configure the piston 12c to be lowered downward (the solenoid valve 12d, the air source). In the above embodiment, an example in which the electromagnetic valve 12d and the air source are used has been described. However, the present invention is not limited thereto. For example, instead of the electromagnetic valve 12d and the air source 12e, electric power may be used. In the above embodiment, an example in which the sliding sleeve 12b and the roller 12ci are used has been described. However, the present invention is not limited thereto. The sliding sleeve 12b and the roller 12A can be omitted as appropriate.
