Description

Technical Field

[0001] This invention relates to the field of cutting technology, and in particular to a composite glass cutting machine and its method of use. Background Technology

[0002] In the display panel manufacturing industry, cutting large-sized glass motherboards (such as G8.5 generation and above) into the required size usually requires multiple processes such as slitting and table cutting. Among them, the slitting process is used to use a slitting machine to initially divide the glass motherboard into two or four halves along the X and Y directions.

[0003] There are two main types of existing glass cutting machines: one is a platform-moving cutting machine, where the blade is fixed in position and the platform moves the glass substrate to achieve unidirectional cutting. Then, an external rotating mechanism rotates the cut glass substrate 90° to complete the vertical cutting. The other is a blade-moving cutting machine, where the platform is fixed in position and the blade moves to achieve unidirectional cutting. Then, an external rotating mechanism rotates the cut glass substrate 90° to complete the vertical cutting. However, both types of cutting machines require multiple transfers of the glass substrate, resulting in large accumulated processing errors, a high risk of glass breakage, and significant impact on production efficiency, failing to meet actual production cycle requirements.

[0004] Therefore, there is an urgent need to develop a cutting machine that does not require the transfer of the glass mother plate during the cutting process, in order to overcome the aforementioned defects. Summary of the Invention

[0005] To overcome the technical defects of existing composite glass cutting machines, such as large cumulative processing errors, high risk of glass breakage, and low production efficiency caused by the need for multiple transfers of the glass mother plate, this invention proposes a composite glass cutting machine and its usage method.

[0006] The composite glass cutting machine provided by this invention includes: frame; A crossbeam assembly, which is fixed on the frame and includes an upper crossbeam and a lower crossbeam, both of which extend along the X direction and are arranged at intervals to form a working window. The cutting assembly includes at least one set, each set comprising two blade groups arranged opposite each other in the Z direction. The two blade groups are respectively mounted on the upper and lower crossbeams and are driven to slide in the X direction. Each blade group includes a blade holder, a Z-direction drive member, a blade base, and a blade head. The blade holder is connected to the corresponding upper or lower crossbeam. The fixing part of the Z-direction drive member is fixedly connected to the blade holder, and the output part of the Z-direction drive member is fixedly connected to the blade base. The blade head is mounted on the blade base. The blade head of at least one set of the cutting assembly is a rotating head, which is driven to rotate relative to the blade base to form a cutting edge arranged in the X or Y direction. The platform component includes two coplanar conveying platforms located on either side of the working window, each conveying platform being driven to convey products along the Y direction.

[0007] Optionally, the crossbeam assembly further includes a base and support blocks. The base is fixed to the frame, and two support blocks are provided and respectively fixed between the two ends of the upper and lower crossbeams.

[0008] Optionally, the Z-axis drive includes a servo motor, a cam, a sliding seat, and a return spring. The housing of the servo motor is fixed on the tool holder and its output shaft is arranged along the Z-axis. The cam is fixed on the output shaft of the servo motor. The sliding seat is mounted on the tool holder and can slide along the Z-axis. The return spring is connected between the sliding seat and the tool holder and is used to drive the top end of the sliding seat to abut against the cam. The tool holder is fixed on the sliding seat.

[0009] Optionally, the rotating head is mounted on the tool holder via a rotary motor, the housing of the rotary motor is fixed to the tool holder and the output shaft is arranged along the Z direction, and the rotating head is fixed on the output shaft of the rotary motor.

[0010] Optionally, a limiting structure is further provided between the sliding seat and the tool holder, the limiting structure being used to limit the lower limit position of the sliding seat.

[0011] Optionally, in each cutting assembly, the upper blade assembly also includes a vision camera for detecting the position of the product.

[0012] Optionally, the cutting assembly is provided in two sets. One set of the cutting assembly has a rotating head as the cutting head, and the other set of the cutting assembly has a fixed head as the cutting head. The fixed head is fixed on the cutting head, and the cutting edge of the fixed head is arranged along the Y direction.

[0013] The method of using the composite glass cutting machine provided by the present invention includes the following steps: S1. Select a set of cutting components and arrange the blades of the cutting components along the Y direction; S2. Move the set of cutting components along the X direction to the Y direction cutting position of the glass mother plate; S3. The glass mother plate is conveyed forward along the Y direction by the platform component, and the Y-direction cutting of the glass mother plate is completed by the set of cutting components; S4. Select the cutting head as the rotary head cutting assembly and adjust the cutting edge of the rotary head to the X direction; S5. The glass mother plate is conveyed backward along the Y direction by the platform component until the X-direction cutting position of the glass mother plate is aligned with the blade of the cutting component; S6. The glass mother plate is cut in the X direction by moving the cutting assembly along the X direction.

[0014] Optionally, if the glass motherboard has multiple Y-axis cutting positions, repeat steps S1 to S3 until all Y-axis cuttings are completed; if the glass motherboard has multiple X-axis cutting positions, repeat steps S4 to S6 until all X-axis cuttings are completed.

[0015] Optionally, if the glass mother plate has multiple Y-direction cutting positions and at least two sets of cutting components are provided, then in step S2, each cutting component is moved to a different Y-direction cutting position on the glass mother plate so that cutting at least two Y-direction cutting positions can be completed simultaneously in step S3.

[0016] The technical solution provided by this invention has the following advantages compared with the prior art.

[0017] The composite glass cutting machine provided by this invention has a cutting component that can move along the X-axis, a platform component that can transport products along the Y-axis, and at least one set of cutting components has a rotating head that is driven to rotate relative to the cutter holder to form blades arranged along the X or Y-axis. The composite structure thus formed can complete the Y-axis cutting of the product by the Y-axis transport of the platform component and the X-axis cutting of the product by the X-axis movement of the cutting component. Moreover, the rotating head can adapt the blades to different cutting directions by rotating, without the need for an external rotating mechanism to rotate the product. This overcomes the technical defects of the prior art, such as large cumulative processing errors, high risk of glass breakage, and low production efficiency caused by product rotation.

[0018] The composite glass cutting machine provided by this invention does not require rotating the glass mother plate. It can complete X and Y bidirectional cutting simply by bidirectional conveying of the platform component and switching of the direction of the cutter head, achieving the same beneficial effects as the aforementioned equipment.

[0023] To better understand the above-mentioned objectives, features, and advantages of the present invention, the solutions of the present invention will be further described below. It should be noted that, unless otherwise specified, the embodiments of the present invention and the features thereof can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the invention, but the invention may also be practiced in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of the invention, and not all embodiments.

[0025] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0026] Reference Figure 1 This embodiment provides a composite glass cutting machine, including a frame 1, a crossbeam assembly 2, a cutting assembly 3, and a platform assembly 4.

[0027] Among them, rack 1 is used to provide hardware support for other components.

[0028] Specifically, the structure of frame 1 is not limited; for example, it can be a plate structure, a frame structure, or a platform structure.

[0029] Among them, reference Figure 2 The crossbeam assembly 2 is fixed on the frame 1 and includes an upper crossbeam 21 and a lower crossbeam 22. Both the upper crossbeam 21 and the lower crossbeam 22 extend along the X direction, and the upper crossbeam 21 and the lower crossbeam 22 are arranged at intervals to form a working window 23.

[0030] Specifically, such as Figure 2 As shown, in this embodiment, the crossbeam assembly 2, in addition to the upper crossbeam 21 and the lower crossbeam 22, also includes a base 24 and support blocks 25. The base 24 is fixed to the frame 1, and two support blocks 25 are provided and respectively fixed between the two ends of the upper crossbeam 21 and the lower crossbeam 22. The base 24 is used to fix the lower crossbeam 22 on the frame 1, and the support blocks 25 are used to achieve the relative spacing between the upper crossbeam 21 and the lower crossbeam 22. This crossbeam assembly 2 adopts a modular structure, which is convenient to assemble and more conducive to production and processing. In other embodiments, the crossbeam assembly 2 can also adopt an integrated structure.

[0031] More specifically, the structure of the base 24 and the support block 25 is not limited, for example Figure 2 As shown, in this embodiment, the base 24 is a block structure and the support block 25 is an I-beam.

[0032] It is easy to understand that the working window 23 is used for the product to move through, thereby completing the cutting of the product in a cutting manner.

[0033] Among them, reference Figures 2 to 5 At least one set of cutting components 3 is provided. Each set of cutting components 3 includes two blade groups arranged opposite each other in the Z direction. The two blade groups are respectively installed on the upper crossbeam 21 and the lower crossbeam 22 and are driven to slide in the X direction. The blade group includes a blade holder 31, a Z-direction drive member 32, a blade seat 33 and a blade head 34. The blade holder 31 is connected to the corresponding upper crossbeam 21 or lower crossbeam 22. The fixing part of the Z-direction drive member 32 is fixedly connected to the blade holder 31. The output part of the Z-direction drive member 32 is fixedly connected to the blade seat 33. The blade head 34 is installed on the blade seat 33. The blade head 34 of at least one set of cutting components 3 is set as a rotating head 341. The rotating head 341 is driven to rotate relative to the blade seat 33 to form a blade arranged in the X or Y direction.

[0034] Specifically, there is no limit to the number of cut components 3, for example Figure 2 As shown in the figure, this embodiment is provided with two sets of cutting components 3.

[0035] Specifically, the mounting of the cutter assembly on the corresponding crossbeam and the drive structure are not limited, for example... Figure 2 As shown, in this embodiment, the tool assembly is mounted on the corresponding crossbeam via a slide rail pair 26 and is connected to a lead screw pair 27. The slide rail pair 26 ensures the sliding accuracy of the tool assembly, and the lead screw pair 27 drives the tool assembly to move along the slide rail pair.

[0036] It should be noted that each tool set requires a lead screw pair 27, but the slide rail pair 26 can be configured separately or shared, for example... Figure 2As shown, in this embodiment, two sets of slide rail pairs 26 are provided on the upper crossbeam 21 and the lower crossbeam 22, which are distributed vertically. The two sets of slide rail pairs 26 are respectively connected to the upper and lower ends of the blade assembly to improve the motion accuracy. Two sets of lead screw pairs 27 are provided and located between the two sets of slide rail pairs 26. The two sets of lead screw pairs 27 are respectively connected to the middle of the two blade assemblies located on the upper or lower side of the two sets of cutting components 3.

[0037] Specifically, the structure of the tool holder 31 is not limited, for example... Figure 4 As shown, the tool holder 31 in this embodiment is designed as a plate structure.

[0038] Specifically, such as Figure 4 As shown, the Z-axis drive unit 32 in this embodiment includes a servo motor 321, a cam 322, a sliding seat 323, and a return spring. The housing of the servo motor 321 is fixed on the tool holder 31 and the output shaft is arranged along the Z-axis. The cam 322 is fixed on the output shaft of the servo motor 321. The sliding seat 323 is mounted on the tool holder 31 and can slide along the Z-axis. The return spring is connected between the sliding seat 323 and the tool holder 31 and is used to drive the top end of the sliding seat 323 to abut against the cam 322. The tool holder 33 is fixed on the sliding seat 323. When the output shaft of the servo motor 321 rotates, driving the cam 322 to rotate in the forward direction, the local height of the bottom profile of the cam 322 corresponding to the sliding seat 323 gradually decreases, forcing the sliding seat 323 to descend and completing the cutting action of the cutter head 34. When the output shaft of the servo motor 321 rotates, driving the cam 322 to rotate in the reverse direction, the local height of the bottom profile of the cam 322 corresponding to the sliding seat 323 gradually increases, and the sliding seat 323 rises under the action of the return spring and maintains contact with the cam 322, completing the reset. This Z-axis drive 32 has high motion accuracy, and the height range of the bottom profile of the cam 322 determines the stroke of the cutter head 34, resulting in strong stroke controllability. In other embodiments, the Z-axis drive 32 can also be a linear motor or other commonly used linear power components.

[0039] More specifically, the mounting method of the slide block 323 on the tool holder 31 is not limited, for example... Figure 4 As shown, in this embodiment, a mounting plate 311 is fixedly provided on the tool holder 31, and a guide rail pair 312 is provided on the mounting plate 311. The sliding seat 323 is fixedly connected to the slider of the guide rail pair 312.

[0040] As an improved structure of the slide block 323, such as Figure 4 As shown, in this embodiment, a limiting structure 35 is also provided between the sliding seat 323 and the tool holder 31. The limiting structure 35 is used to limit the lower limit position of the sliding seat 323.

[0041] Specifically, in this embodiment, one set of cutting components 3 has a rotating head 341 for the blade 34, while the other set has a fixed head 342 for the blade 34. The fixed head 342 is fixed on the blade holder 33, and the blade of the fixed head 342 is arranged along the Y direction. The fixed head 342 is used for Y-axis cutting of the product; the rotating head 341 can be used for both Y-axis and X-axis cutting of the product by rotation.

[0042] It is easy to understand that if there is only one set of cutting components 3, the cutter head 34 of that set of cutting components 3 must be designed as a rotating head 341; if there are two or more sets of cutting components 3, at least one set of cutting components 3 must be designed as a rotating head 341. In actual design, even if there are two or more sets of cutting components 3, only one set of cutting components 3 is designed as a rotating head 341. This is because all cutting components 3 are mounted on the corresponding crossbeams, meaning that the trajectories of all cutting components 3 in the X direction overlap. If the cutter heads 34 of two or more sets of cutting components 3 are designed as rotating heads 341, it will not only fail to improve efficiency, but will also cause problems such as stroke avoidance between rotating heads 341, making the design more complex.

[0043] It should be noted that, as Figure 5 and Figure 6 As shown, the auxiliary structures such as the tool holder 31 and the Z-axis drive component 32 attached to the rotating head 341 and the fixed head 342 are exactly the same. The core difference lies in the structure of the tool head 34. The tool holder 33 can be designed the same or adapted to different tool head 34 structures.

[0044] It should be noted that the cutter head 34 is not limited to the cutting wheel: for double-layer glass, both cutter heads 34 of the same cutting assembly 3 should be cutting wheels; for single-layer glass, one of the cutting wheels can be replaced with a support wheel, but whether it is a cutting wheel or a support wheel, its blade direction is defined as a horizontal line direction perpendicular to its axis of rotation.

[0045] Specifically, such as Figure 5 As shown, in this embodiment, the rotating head 341 is mounted on the tool holder 33 via a rotary motor 343. The housing of the rotary motor 343 is fixed to the tool holder 33, and its output shaft is arranged along the Z-axis. The rotating head 341 is fixed on the output shaft of the rotary motor 343. The rotation of the output shaft of the rotary motor 343 drives the rotating head 341 to rotate, thereby causing the cutting edge of the rotating head 341 to switch between the X and Y axes. In other embodiments, the rotating head 341 can also be mounted on the tool holder 33 via a servo motor, a rotary cylinder, or other commonly used rotary power structures.

[0046] More specifically, the mounting structure of the rotating head 341 is not limited, for example... Figure 5As shown, in this embodiment, the rotating head 341 is mounted in the tool holder 33 by bearings, and the top end of the rotating head 341 is fixedly connected to the output shaft of the rotary motor 343 by coupling 344.

[0047] As an improved structure of the cutting component 3, such as Figure 3 As shown, in each cutting assembly 3 of this embodiment, the upper blade assembly also includes a vision camera 36, ​​which is used to detect the position of the product. The vision camera 36 can adopt a structure commonly used in the art, such as a CCD.

[0048] The platform component 4 includes two coplanar conveying platforms 41 located on both sides of the working window 23, and each conveying platform 41 is driven to convey products along the Y direction.

[0049] Specifically, the conveyor platform 41 can adopt a structure commonly used in this field, such as a synchronous belt.

[0050] The method of using the composite glass cutting machine provided in this embodiment includes the following steps: S1. Select a set of cutting components 3 and arrange the blades of the set of cutting components 3 along the Y direction; S2. Move the set of cutting components 3 along the X direction to the Y-direction cutting position of the glass mother plate; S3. Transport the glass mother plate forward along the Y direction through the platform component 4, and complete the Y-direction cutting of the glass mother plate through the set of cutting components 3; S4. Select the cutting head 34 as the cutting component 3 with the rotating head 341, and adjust the blade of the rotating head 341 to the X direction; S5. Transport the glass mother plate backward along the Y direction through the platform component 4 until the X-direction cutting position of the glass mother plate is aligned with the blade of the cutting component 3; S6. Complete the X-direction cutting of the glass mother plate by moving the cutting component 3 along the X direction.

[0051] It is easy to understand that in step S1, if the blade 34 of the cutting assembly 3 is selected as the fixed head 342, it can be used directly; if the blade 34 of the cutting assembly 3 is selected as the rotating head 341, the blade of the rotating head 341 needs to be adjusted to be arranged along the Y direction. The former solution is preferred because the blade direction of the fixed head 342 does not need to be adjusted, there is no adjustment error, and the cutting accuracy in the Y direction is higher.

[0052] Specifically, if the glass motherboard has multiple Y-axis cutting positions, repeat steps S1 to S3 until all Y-axis cuts are completed; if the glass motherboard has multiple X-axis cutting positions, repeat steps S4 to S6 until all X-axis cuts are completed. When both the X-axis and Y-axis cutting positions are set to one, a "four-way" cut of the glass template can be achieved; when both the X-axis and Y-axis cutting positions are set to two, a "nine-way" cut of the glass template can be achieved; when both the X-axis and Y-axis cutting positions are set to three, a "twelve-way" cut of the glass template can be achieved; and so on.

[0053] Specifically, if the glass mother plate has multiple Y-axis cutting positions and at least two sets of cutting components 3 are provided, then in step S2, each cutting component 3 is moved to a different Y-axis cutting position on the glass mother plate so that cutting at least two Y-axis cutting positions can be completed simultaneously in step S3. For example, in the composite glass cutting machine of this embodiment, one set of cutting components is designed as a fixed head 342 and the other is designed as a rotating head 341. After the blade direction of the rotating head 341 is adjusted to the Y-axis, the two sets of cutting components are moved to two different Y-axis cutting positions on the glass mother plate so that cutting at two Y-axis cutting positions can be completed simultaneously.

[0054] It should be noted that the composite glass cutting machine and its usage method in this embodiment are not only applicable to the display panel field, but also, with appropriate cutter wheel selection and parameter adjustment, applicable to the precision grid cutting of other brittle materials such as photovoltaic glass, cover glass, and decorative glass.

[0055] The above description is merely a specific embodiment of the present invention, enabling those skilled in the art to understand or implement the present invention. Although detailed descriptions have been provided with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments, and they should all be covered within the protection scope of the claims.
