[0024] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.
[0025] Example 1 Figure 1 This is a top view schematic diagram of the glass substrate cutting straightness device disclosed in this embodiment, as shown below. Figure 1 As shown, this embodiment of the present disclosure provides a glass substrate cutting straightness device, including: a blade holder 2, a blade wheel 4, a distance sensor 3, a standard straightness standard part 7, a servo motor 8, and a control circuit 10.
[0026] The cutter wheel 4 is connected to the cutter holder 2, and the cutter holder 2 drives the cutter wheel 4 to move in a straight line to cut the target glass plate.
[0027] Specifically, the cutter holder is the direct carrier of the cutter wheel, and it ensures that the cutter wheel maintains a relatively stable posture during the cutting process to cut the glass substrate evenly.
[0028] In some embodiments, the cutter holder is provided with a lifting mechanism, which drives the cutter wheel to move vertically to meet the cutting needs of glass of different thicknesses. The cutting wheel is typically made of superhard materials such as diamond. When the cutting wheel moves in a straight line, its sharp edge presses a continuous, uniformly deep, tiny scratch on the glass surface. The scratch disrupts the stress balance on the glass surface, creating stress concentration points. When external forces, such as mechanical breaking or thermal stress, are applied to the scratch, cracks will steadily propagate along the scratch direction, ultimately achieving the separation of the glass.
[0029] It should be noted that, in the specific implementation of this application, the cutter wheel is connected to the cutter holder and the cutter wheel can move laterally along the x-direction. Specifically, firstly, the cutter holder supports the cutter wheel; secondly, when the cutter holder moves vertically along the y-direction, it drives the connected cutter wheel to move vertically along the y-direction to cut the glass; simultaneously, the cutter wheel can move laterally along the x-direction to achieve local fine-tuning, so as to maintain the straightness of the cutter wheel cutting the glass vertically along the y-direction.
[0030] In some embodiments, the design of the cutter wheel being connected to the tool holder and being able to move left and right can be achieved through a sliding fit connection. The tool holder has a sliding groove inside, and the cutter wheel is connected to the tool holder through a sliding block. The sliding block can slide within the sliding groove, thereby realizing the left and right movement of the cutter wheel.
[0031] Distance sensor 3 is mounted on cutter wheel 4. Distance sensor 3 is used to measure the real-time distance between standard straightness standard part 7 and cutter wheel 4.
[0032] Among them, the standard straightness standard part is a reference element that has undergone precision machining and rigorous testing. During measurement, it serves as the physical embodiment of an ideal straight line, providing a comparison benchmark for the measured part. The distance sensor can calculate the distance by measuring the time interval from signal transmission to reflection and reception. In the specific implementation process, an ultrasonic distance sensor or an infrared distance sensor can be used to determine the real-time distance between the standard straightness standard part and the cutting wheel.
[0033] It should also be noted that the distance sensor 3 is fixedly connected to the cutter wheel 4, and the distance sensor moves left and right with the cutter wheel.
[0034] In some embodiments, a snap-fit mechanism can be used to achieve a fixed connection between the distance sensor and the cutter wheel. Specifically, the snap-fit mechanism includes a hook and a slot, with the hook located on the distance sensor and the slot located on the cutter wheel. The hook engages with the slot on the cutter wheel through elastic deformation to lock the distance sensor, and the slot accommodates the hook and allows it to deform and engage in a locking mechanism.
[0035] The control circuit 10 is used to control the servo motor 8 mounted on the tool holder to drive the tool wheel 4 to move so as to adjust the real-time distance to the standard distance when the real-time distance deviates from the standard distance.
[0036] The servo motor is connected to the cutter wheel. The servo motor provides the power and control core, while the cutter wheel acts as the actuator to convert the motion of the servo motor into the corresponding displacement.
[0037] It is understandable that in glass substrate cutting operations, the cutter head moves in a straight line on the guide rail to cut the glass. Due to long-term processing, the guide rail is prone to wear, resulting in poor straightness of the glass cutting on all four sides, and some areas may be overcut or undercut. To address this defect, the embodiments of this application first set the standard distance between the distance sensor and the standard straightness standard as D. During glass substrate cutting, the control circuit communicates with the distance sensor to read the real-time distance d between the cutter wheel and the standard straightness standard detected by the distance sensor. By comparing the standard distance D and the real-time distance d, the servo motor is controlled to drive the cutter wheel to move left and right to adjust the cutting straightness.
[0038] In some embodiments, the control circuit 10 is a PLC control circuit. The PLC control circuit supports instructions such as logic operations, arithmetic operations, data processing, and communication to meet complex control requirements. Through digital or analog input / output modules, it connects to devices such as sensors and actuators to achieve real-time control. In the specific implementation process, the control circuit communicates with the distance sensor to read the real-time distance between the cutter wheel and the standard straightness standard part detected by the distance sensor, and communicates with the servo motor to control the servo motor to drive the cutter wheel to move left and right to adjust the cutting straightness.
[0039] In some embodiments, the control circuit 10 controls the servo motor 8 mounted on the tool holder to drive the tool wheel 4 to move in order to adjust the real-time distance d to the standard distance D, including: When Dd > 0, it indicates that a short cut has occurred, and the control circuit 10 controls the servo motor 8 to move to the right by Dd; and when Dd < 0, it indicates that an over-cut has occurred, and the control circuit 10 controls the servo motor 8 to move to the left by |Dd|.
[0040] It is understandable that during the entire cutting process corresponding to the target glass substrate, the servo motor 8 drives the cutter wheel 4 to move left and right in real time to adjust, which can avoid over-cutting or under-cutting in some local positions due to changes in the straightness of the guide rail, thereby improving the straightness of glass cutting.
[0041] In some embodiments, the glass substrate cutting straightness device further includes an input device 11, which is used to set different cutting positions d. n The corresponding corrected distance x n ; Specifically, the input device is a touch screen or touchpad, and the correction distance can be determined in the following way: multiple glass substrate samples are pre-selected for glass cutting tests, and the straightness of the four cut edges of the multiple glass substrate samples is analyzed and compared to determine the correction distance corresponding to different positions of any cut edge.
[0042] Different cutting positions can be set via input device 11. n The corresponding corrected distance x n Afterwards, the control circuit moves the tool holder 2 to the position shown in the image. Figure 2 The cutting position d shown n When the corrected distance x n When <0, control servo motor 8 to drive cutter wheel 4 to move to the left |x n |; and when the corrected distance x n When the value is greater than 0, control the servo motor 8 to drive the cutter wheel 4 to move x to the right. n .
[0043] Figure 2 This is a partial structural schematic diagram of the glass substrate cutting straightness device disclosed in this embodiment, with reference to... Figure 2 The specific application process of the correction distance will be further explained.
[0044] like Figure 2As shown, the positions of the glass substrate samples after experimental cutting corresponding to the standard straightness standard 7 are denoted as P1, P2, P3...P n The touchscreen is set to position P1 as d1, position P2 as d2, position P3 as d3…P n Position d n The left and right movement data d is controlled by a PLC control circuit. n Send to servo motor 8, when d n When d > 0, servo motor 8 controls the cutter wheel 4 to move to the right; when d n When d < 0, servo motor 8 controls the cutter wheel 4 to move to the left. n When the value is 0, the servo motor 8 controls the cutter wheel 4 to not move and does not perform any correction.
[0045] Similarly, the other three edges of the glass substrate are cut and corrected using the same principle to complete the straightness adjustment of the cutting and grinding operation.
[0046] In some embodiments, the standard straightness standard 7 is arranged perpendicularly to the tool holder 2.
[0047] In some embodiments, the glass substrate cutting straightness device further includes a worktable 9 located below the tool holder 2 for supporting the target glass plate, and a standard straightness standard 7 located on the side of the worktable 9.
[0048] In some embodiments, the glass substrate cutting straightness device further includes: a first belt 13, a connecting plate 12, and a guide rail 1; the connecting plate 12 is disposed on the first belt 13 and is used to connect the tool holder 2 and the first belt 13; the first belt 13 drives the tool holder 2 to move along the guide rail 1 through the connecting plate 12.
[0049] It is understandable that the cutter holder moves linearly along the guide rail, which can complete the horizontal or vertical cutting of the glass substrate.
[0050] In some embodiments, the connecting plate 12 is a clamping component that is clamped onto the first belt 13 and moves with the belt.
[0051] In some embodiments, the glass substrate straightness cutting device further includes: Tool holder drive motor 6, second belt 5, pulley 14 and drive shaft 15; The tool post drive motor 6 is used to provide driving power to the connected pulleys 14, wherein the two pulleys 14 are connected by a second belt 5 to transmit driving power; The pulley 14 transmits driving power to the connected drive shaft 15, and the drive shaft 15 transmits driving power to the connected first belt 13.
[0052] It is understandable that pulleys, in conjunction with belts and drive shafts, can achieve power transmission, motion conversion, and speed regulation.
[0053] This application embodiment also provides a glass production line, which includes a glass plate production device and the above-mentioned glass substrate cutting straightness device; The glass substrate cutting straightness device is located at the rear end of the glass plate production device and is used to cut the glass produced by the glass plate production device.
[0054] Example 2 Example 2 is based on Example 1. Figure 3 This is a top view schematic diagram of the glass substrate cutting straightness device disclosed in this embodiment, as shown below. Figure 3 As shown, the glass substrate cutting straightness device includes a blade holder 2, two standard straightness standard parts 7, a first correction unit 101, a second correction unit 102, a control circuit 10, and a worktable 9.
[0055] The first correction unit 101 is located on the left side of the tool holder and includes: a tool wheel 4, a distance sensor 3, and a servo motor 8; the second correction unit 102 is located on the right side of the tool holder and includes: a tool wheel 4, a distance sensor 3, and a servo motor 8. The worktable 9 is located below the tool holder 2 and is used to support the target glass plate. Two standard straightness standard parts 7 are located on the left and right sides of the worktable 9, respectively; one standard straightness standard part is located on the left side of the first correction unit 101, and the other standard straightness standard part is located on the right side of the second correction unit 102.
[0056] For the first correction unit 101: the cutter wheel 4 is connected to the cutter holder 2, and the cutter holder 2 drives the cutter wheel 4 to move along a straight line to cut one edge of the target glass plate; the distance sensor 3 is set on the cutter wheel 4, and the distance sensor 3 is used to measure the real-time distance between the standard straightness standard 7 set on the left side of the first correction unit 101 and the cutter wheel 4; the control circuit 10 is used to control the servo motor 8 set on the cutter holder to drive the cutter wheel 4 to move so as to adjust the real-time distance to the standard distance when the real-time distance deviates from the standard distance. Specifically, when Dd > 0, it indicates that there is a short cut at this position, and the control circuit 10 controls the servo motor 8 in the first correction unit 101 to move to the right by Dd; and when Dd < 0, it indicates that there is an over-cut at this position, and the control circuit 10 controls the servo motor 8 in the first correction unit 101 to move to the left by |Dd|.
[0057] For the second correction unit 102: the cutter wheel 4 is connected to the cutter holder 2, and the cutter holder 2 drives the cutter wheel 4 to move along a straight line to cut one edge of the target glass plate; the distance sensor 3 is set on the cutter wheel 4, and the distance sensor 3 is used to measure the real-time distance between the standard straightness standard 7 set on the right side of the second correction unit 102 and the cutter wheel 4; the control circuit 10 is used to control the servo motor 8 set on the cutter holder to drive the cutter wheel 4 to move to adjust the real-time distance to the standard distance when the real-time distance deviates from the standard distance, including: when Dd>0, it indicates that there is a short cut at this position, and the control circuit 10 controls the servo motor 8 in the second correction unit 102 to move to the left by Dd; and when Dd<0, it indicates that there is an over-cut at this position, and the control circuit 10 controls the servo motor 8 in the second correction unit 102 to move to the right by |Dd|.
[0058] It is understood that the first correction unit 101 and the second correction unit 102 operate simultaneously. The first correction unit 101 cuts one edge of the glass substrate, and the second correction unit 102 cuts one edge of the glass substrate. Both edges of the glass substrate can be cut and scribing at the same time, thereby reducing the processing time and improving the processing efficiency.
[0059] The glass substrate cutting straightness device provided in this application embodiment, when cutting and scribing the glass substrate, the control circuit communicates with the distance sensor to read the real-time distance between the cutting wheel and the standard straightness standard piece detected by the distance sensor in real time, and controls the servo motor to drive the cutting wheel to move left and right to adjust the cutting straightness. On the one hand, it effectively improves the straightness of the four sides of the glass after cutting, thereby reducing the occurrence of such edge defects, and on the other hand, it can reduce processing loss and save processing costs.
