Description

Technical Field

[0001] The present application relates to the field of laser cutting of curved screens, and in particular to a device and method for laser cutting of glass substrates for display screen processing. Background Art

[0002] At present, the curved screen is a display screen made of flexible plastic, which is mainly realized by OLED panel. Compared with the flat screen, the curved screen has better elasticity and is not easy to break. In the production process of the curved screen, there is a process to cut the curved glass substrate, which is usually cut by laser cutting equipment. However, the existing laser cutting equipment for curved screens can usually only cut glass substrates with fixed curvature. When the curvature of the produced curved screen changes, the curvature of the corresponding glass substrate changes, and the cutting device for cutting the corresponding curvature needs to be replaced, which is very inconvenient and greatly increases the production cost.

[0003] In the related art, a Chinese patent with a patent publication number of CN114669889A proposes a glass substrate slitting device for display screen processing, including a substrate, a first telescopic sleeve, a connecting rod, a roller, an adjustment mechanism, a circular cutting mechanism, a material pushing mechanism and a supporting mechanism. A plurality of the first telescopic sleeves are equidistantly fixed in the middle of the upper surface of the substrate, and a plurality of the first telescopic sleeves are arranged in five rows at equal angles, and the protruding ends of the first telescopic sleeves in the same row on the substrate are fixed with a connecting rod, the roller is rotatably connected to the protruding ends of the first telescopic sleeves through an axle pin, and the adjustment mechanism is fixed in the middle of the substrate for adjusting the protruding length of the first telescopic sleeve; the above technical scheme can cut glass substrates of various curvatures, and the adjustment process is fast and convenient, and can adapt to the production of curved screens of various curvatures, which greatly reduces the production cost of the enterprise, and the adjustment process is relatively fast and can greatly improve the overall production efficiency.

[0004] With respect to the above-mentioned related technologies, the inventors believe that there are the following defects: after the curved screen is cut, it cannot be guaranteed that the curved screen is completely cut. For example, insufficient cutting distance or laser cutting failure may result in failure to cut the curved screen. Therefore, it is necessary to inspect the curved screen after cutting.

Then the perforations on the connecting piece are controlled to move under the two vacuum suction cups, and then the vacuum suction cups are controlled to move downward and adsorbed on the two parts of the corresponding glass substrate respectively. Since the premise that the glass substrate can move with the conveying plate is that the friction between the glass substrate and the conveying plate can make it move, but it is also possible that the friction between the glass substrate and the conveying plate is not enough to make the glass substrate move with the conveying plate, so the glass substrate moving with the conveying plate is the premise of the test work, so the trigger component needs to identify the movement of the glass substrate and the conveying plate together; 2.

The first buzzer and the tension sensor are connected through the control of the PLC controller. The first buzzer sounds an alarm, which means that the two glass substrates have been cut. If the tension sensor detects that the value has not changed, the value of the tension sensor will not change. 3. Before the glass substrate is cut, if the conveying plate does not move with the corresponding glass substrate, when the fastening plate moves toward one side of the glass substrate, the buffer ring contacts the glass substrate first, and as the gear continues to rotate, the buffer ring is continuously squeezed and deformed. When the first electromagnet moves to abut against the glass substrate, the identification rod abuts against the proximity switch. The proximity switch and the first electromagnet are connected through the control of the PLC controller. The proximity switch controls the first electromagnet to be energized, and the two first electromagnets are attracted to each other, thereby completing the effect of fastening the conveying plate and the corresponding glass substrate.

DETAILED DESCRIPTION

[0019] The following is combined with Figure 1-5 This application is described in further detail.

[0020] Embodiment 1

[0021] The present application discloses a glass substrate laser cutting device for display screen processing. Figure 1-Figure 5A glass substrate laser cutting device for display screen processing includes a frame 1, a conveying mechanism for conveying a glass substrate, a supporting mechanism 4 for supporting the glass substrate, and a detection mechanism for detecting whether the glass substrate is cut. The conveying mechanism includes a conveying plate 2 and a power unit 3 for controlling the movement of the conveying plate 2. The power unit 3 in this embodiment can be an electric push rod or a gear 39 and a rack 40. It only needs to ensure that the conveying plate 2 moves on the frame 1. The supporting mechanism 4 can be adjusted according to the different curvatures of the glass substrate. For example, in the prior art, multiple groups of supporting balls with variable lengths are used, which can be adjusted according to the different curvatures of the glass substrate. Adaptation can be achieved, thereby realizing the conveying and cutting of glass substrates with different curvatures. During the conveying process, the supporting mechanism 4 always supports the glass substrate; and the present embodiment also includes a cutting mechanism for cutting the glass substrate, the cutting mechanism includes a bracket 5 rotatably arranged on the frame 1 and a laser cutting device 6 arranged on the bracket 5; the rotation of the bracket 5 is realized by a motor, and the laser cutting device 6 starts to rotate following the bracket 5. Due to the curvature of the glass substrate, the distance from the cutting position of the glass substrate will change during the rotation of the laser cutting device 6, but it will not affect the normal cutting work of the laser cutting device 6. When the laser cutting device 6 completes the rotation, the cutting is completed.

[0022] The detection mechanism includes a detection frame 7 which is lifted and arranged on the bracket 5, two adsorption components, an identification component for connecting the two adsorption components, a judgment component for judging whether the cut substrate moves, and a fastening component for adsorbing the moving substrate. The two parts of the cut glass substrate are adsorbed respectively by the two adsorption components, and the identification component is used to identify whether the two parts of the glass substrate are in relative position. If they are in relative position, they are identified by the identification component. Since one part of the glass substrate is located on the conveying plate 2 and the other part is located on the frame 1 during the cutting process, the part of the glass substrate located on the conveying plate 2 is judged by the judgment component to determine whether the conveying plate 2 can drive the part thereon to move together. If not, the fastening component is required to fasten the glass substrate to ensure that the glass substrate moves with the conveying plate 2.

[0023] The adsorption assembly includes two vacuum suction cups 8 and a cleaning part for cleaning the position where the vacuum suction cups 8 adsorb the glass substrate. The two vacuum suction cups 8 are respectively located on both sides of the cutting position of the glass substrate. The vacuum suction cups 8 are used to adsorb the glass substrate. The vacuum suction cups 8 are arranged on the detection frame 7. The vacuum suction cups 8 and the detection frame 7 are detachably connected through the second electromagnet 49. The second electromagnet 49 is fixed on the detection frame 7. The second electromagnet 49 adsorbs and fixes the vacuum suction cups 8. When the vacuum suction cups 8 and the glass substrate are adsorbed, the second electromagnet 49 starts to be powered off, and the vacuum suction cups 8 are separated from the detection frame 7. The vacuum suction cups 8 are adsorbed on the glass substrate by vacuuming. The cleaning part is used to adsorb the position where the vacuum suction cup 8 is adsorbed so as not to affect the adsorption effect. Since the position of the glass substrate to be cut is fixed, the position of the vacuum suction cup 8 can also be fixed, that is, it can be located on both sides of the laser cutting equipment 6. The cleaning part includes a cleaning frame 9 that is lifted and arranged on the detection frame 7, a connecting piece 11 that is movably arranged on the cleaning frame 9, a plurality of tapes, and a traction group for traction of the connecting piece 11. The plurality of connecting pieces 11 and the plurality of tapes are arranged at intervals. The connecting piece 11 is provided with a through hole 12 for the vacuum suction cup 8 to pass through. When the vacuum suction cup 8 moves downward, the through hole 12 on the connecting piece 11 is located directly below the vacuum suction cup 8. In this embodiment, the control needs to first lower the connecting piece 11 to below the vacuum suction cup 8 before the tape can be controlled to move to below the vacuum suction cup 8. Similarly, the connecting piece 11 can only be moved upward after the through hole 12 on the connecting piece 11 is moved to below the vacuum suction cup 8.

[0024] The lifting of the detection frame 7 and the lifting of the cleaning frame 9 on the detection frame 7 can be achieved by a cylinder or an electric push rod. The connecting piece 11 is made of plastic material. The tape and the connecting piece 11 are arranged at intervals, and the perforation 12 is used for the two vacuum suction cups 8 to pass through together to avoid affecting the normal operation of the vacuum suction cups 8. The traction group includes two traction rollers 10 and two traction motors. The traction rollers 10 are rotatably arranged on the cleaning frame 9. The traction motor is installed on the cleaning frame 9 and is used to control the rotation of the traction rollers 10. The connecting pieces 11 at both ends are fixedly connected to the outer peripheral walls of the two traction rollers 10 respectively. The traction motor controls the rotation of the traction rollers 10, and the connection is pulled by the mutual cooperation of the two traction rollers 10. The perforations 12 on the sheet 11 are moved to the position directly below the two vacuum suction cups 8, and when the inspection begins, the adhesive tape needs to be moved to the position below the vacuum suction cups 8. In this embodiment, corresponding guide rollers can be provided to ensure that the adhesive tape can be smoothly moved to the position in contact with the glass substrate. During the downward movement of the adhesive tape, the dust on the glass substrate is adhered to the adhesive tape. Then the cleaning rack 9 is pulled upward, and the adhesive tape moves upward with the cleaning rack 9. After the adhesive tape is separated from the glass substrate, the cleaning effect of the glass substrate is completed. Then the perforations 12 on the connecting sheet 11 are controlled to move to the position below the two vacuum suction cups 8, and then the vacuum suction cups 8 are controlled to move downward and adsorbed to the two parts of the corresponding glass substrate respectively.

[0025] The identification component includes an identification rope 13, a tension sensor 14, and an adjustment part for adjusting the identification rope 13 and the tension sensor 14. The two ends of the identification rope 13 are fixedly connected to the two vacuum suction cups 8 respectively. The identification rope 13 is divided into two sections and connected through the tension sensor 14. The tension sensor 14 is electrically connected to a first buzzer 17. The two vacuum suction cups 8 and the identification rope 13 are all passed through the through hole 12. The identification rope 13 is in a straight state in the initial state, and an initial tension value can be set for the tension sensor 14. In this embodiment, it is preferably set to 0. If the tension value detected by the tension sensor 14 during the detection process is greater than the set value, it proves that the two parts of the glass substrate are in relative position and there is a force pulling each other between the two parts of the glass substrate. The first buzzer 17 and the tension sensor 14 are controlled and connected through a PLC controller. The first buzzer 17 sends an alarm, which means that the two glass substrates have been cut. If the tension sensor 14 detects that the value has not changed, the value of the tension sensor 14 will not change. The marking rope 13 is also provided with an avoidance hole 48 for the operation of the laser cutting device 6 .

[0026] The adjusting part includes an adjusting roller 15 rotatably arranged on any vacuum suction cup 8 and an adjusting motor 16 for controlling the rotation of the adjusting roller 15. The adjusting roller 15 is provided with an adjusting hole 18 along its radial direction. The identification rope 13 passes through the adjusting hole 18. Since there may be misoperation during the installation process, resulting in the identification rope 13 not being straightened or the set value of the tension sensor 14 having a problem, it is necessary to adjust whether the identification rope 13 is straightened. Since the identification rope 13 passes through the adjusting hole 18, the adjusting roller 15 winds the identification rope 13 during the rotation process. At this time, the identification rope 13 begins to gradually straighten and controls the value of the tension sensor 14 to reach the set value, or after the value of the tension sensor 14 may be greater than the set value, it is necessary to release the identification rope 13 to make the value of the tension sensor 14 reach the set value.

[0027] The judgment component includes a judgment rope 19, a fixed cylinder 20 fixed on the detection frame 7, a slide cylinder 21 slidably arranged in the fixed cylinder 20, and a trigger component for marking that the fixed cylinder 20 and the slide cylinder 21 start to slide. One end of the judgment rope 19 is fixedly connected to the end of the slide cylinder 21, and the other end of the judgment rope 19 is connected to the vacuum suction cup 8 corresponding to the actively moving glass substrate. In this embodiment, the part of the glass substrate located on the conveying plate 2 is called the actively moving glass substrate. Since the premise that the glass substrate can move with the conveying plate 2 is that the friction between the glass substrate and the conveying plate 2 can make it move, but it is also possible that the friction between the glass substrate and the conveying plate 2 is not enough to make the glass substrate move with the conveying plate 2, so the glass substrate moving with the conveying plate 2 is a prerequisite for the detection work, so the trigger component is required to identify the movement of the glass substrate and the conveying plate 2.

[0028] The trigger assembly includes a plurality of non-woven bags 22, a push plate 23 for pushing the plurality of non-woven bags to move, a push electric push rod 24 for controlling the movement of the push plate 23, a reciprocating electric push rod 25 for realizing the return of the slide cylinder 21 to the initial position, and a slide rod 26 fixedly connected to the slide cylinder 21. The fixed cylinder 20 is provided with a push cavity 27 at the upper end of the slide cylinder 21, the slide cylinder 21 is provided with a storage cavity 28, the push cavity 27 is provided with a push hole 29 connected to the storage cavity 28, the fixed cylinder 20 is provided with a sliding cavity 30 below the slide cylinder 21, and the slide rod 26 is in the sliding cavity 30. Sliding, the reciprocating electric push rod 25 pushes the sliding rod 26 and the sliding cylinder 21 to the initial position, the non-woven bag 22 is filled with reduced iron powder, and a temperature sensor 31 is arranged in the existence cavity, and the temperature sensor 31 is electrically connected to the second buzzer 32. The reduced iron powder will oxidize and generate heat as long as it encounters air. Therefore, in the initial state, the existence cavity is located in the fixed cylinder 20 and no air enters; in the initial state, the reciprocating electric push rod 25 pushes the sliding rod 26 to the end of the sliding cavity 30, at which time the sliding cylinder 21 is also located at one end of the fixed cylinder 20, and the reciprocating electric push rod 2 The output end of 5 is also separated from the slide bar 26, and multiple non-woven fabrics are stored in the push chamber 27. Multiple non-woven bags 22 are arranged in sequence in the push chamber 27. When the non-woven bag 22 needs to be pushed into the storage chamber 28, the push plate 23 is pushed by pushing the electric push rod 24. The push plate 23 pushes the non-woven bag 22 to the position of the push hole 29. The non-woven bag 22 falls from the push hole 29 into the storage chamber 28, and the vacuum suction cup 8 is separated from the detection frame 7. At this time, the conveying plate 2 can be controlled to move in a direction away from the laser cutting equipment 6. If the glass The glass substrate moves with the conveying plate 2. Of course, multiple guide rollers can also be set in this embodiment to ensure that the part where the judgment rope 19 is connected to the slide cylinder 21 is horizontal. The slide cylinder 21 is pulled out of the fixed cylinder 20. At this time, the non-woven bag 22 slides out of the fixed cylinder 20. The reduced iron powder in the non-woven bag 22 encounters air and generates heat. The temperature sensor 31 and the second buzzer 32 are controlled and connected through the PLC controller. At this time, the second buzzer 32 is triggered by the temperature sensor 31 to sound an alarm, which proves that the conveying plate 2 can drive the corresponding glass substrate to move together.

[0029] The sliding cylinder is provided with a phase change chamber 33, and the phase change chamber 33 is vertically arranged. The sliding cylinder 21 is lifted and lowered with a phase change tube 34 in the phase change chamber 33. The phase change tube 34 is filled with a phase change material. The phase change tube 34 moves until it abuts against the tape. The phase change chamber 33 is vertically penetrated. The phase change material in the phase change tube 34 begins to absorb heat to reduce the heat released after the oxidation reaction of the iron powder. The lifting and lowering of the phase change tube 34 is also achieved by an electric push rod or a cylinder, and when the sliding cylinder 21 is in the initial state, the phase change tube 34 is also located outside the fixed cylinder 20. In this embodiment, the movement route of the phase change tube 34 is close to the side where the tape is adhered to the glass substrate. Therefore, after the phase change tube 34 completes the heat storage, and after the tape is adhered to the glass substrate, the tape contacts the phase change tube 34, and the phase change material in the phase change tube 34 begins to release heat. At this time, the side of the tape becomes soft and its viscosity is reduced, but it does not affect the dust that has been adhered. At this time, it is convenient to separate the tape from the glass substrate.

[0030] Reference Figure 1-Figure 5The fastening assembly includes two fastening plates 35, two first electromagnets 36, two buffer rings 37, and a driving unit for moving the two fastening plates 35 toward the glass substrate. The electromagnet is fixed on the fastening plate 35, and the buffer ring 37 is fixed on the fastening plate 35 and is located on the outside of the first electromagnet 36. The two first electromagnets 36 are respectively located on both sides of the glass substrate and adsorbed to each other. The driving unit includes a driving motor 38, a gear 39, and two racks 40. The gear 39 rotates on the conveying plate 2, and the two racks 40 are respectively Located on both sides of the gear 39, the driving motor 38 is fixed on the conveying plate 2 and controls the gear 39 to rotate. The two racks 40 are meshed and connected with the gear 39. The two racks 40 are fixedly connected with the two fastening plates 35 respectively. The buffer ring 37 is made of rubber material, and the thickness of the buffer ring 37 is greater than the thickness of the electromagnet. Therefore, when the fastening plate 35 moves toward one side of the glass substrate, the buffer ring 37 first contacts the glass substrate. As the gear 39 continues to rotate, the buffer ring 37 is continuously squeezed and deformed until The first electromagnet 36 moves to a position where it abuts against the glass substrate, and the first electromagnet 36 starts to be energized. The first electromagnet 36 is attracted to each other, and the conveying plate 2 and the corresponding glass substrate can be fastened. Of course, an identification rod 42 can also be provided to identify the position where the first electromagnet 36 abuts against the glass substrate. The first electromagnet 36 is set in a ring shape. The fastening plate 35 is provided with an identification hole 41 at the center of the first electromagnet 36. A proximity switch 46 is fixedly connected between the inner walls of the ends of the identification hole 41. A limiting block 44 is fixedly connected to the side wall of the identification rod 42. A limiting groove 45 for limiting the movement of the limiting block 44 is provided on the side wall of the identification hole 41. A spring 43 is fixedly connected between the corresponding ends of the limiting block 44 and the limiting groove 45. When the first electromagnet 36 moves to abut against the glass substrate, the identification rod 42 abuts against the proximity switch 46. The proximity switch 46 and the first electromagnet 36 are controlled and connected through a PLC controller. The proximity switch 46 controls the first electromagnet 36 to be energized, thereby achieving the fixing effect of the conveying plate 2 and the corresponding glass substrate.

[0031] The implementation principle of a glass substrate laser cutting device for display processing in an embodiment of the present application is as follows: at the beginning of the detection, the adhesive tape needs to be moved to the bottom of the vacuum suction cup 8 to ensure that the adhesive tape can be smoothly moved to the position where it fits with the glass substrate. During the downward movement of the adhesive tape, the dust on the glass substrate is adhered to the adhesive tape. Then the cleaning rack 9 is pulled upward, and the adhesive tape moves upward with the cleaning rack 9. After the adhesive tape is separated from the glass substrate, the cleaning effect of the glass substrate is completed. Then the perforations 12 on the connecting piece 11 are controlled to move to the bottom of the two vacuum suction cups 8, and then the vacuum suction cups 8 are controlled to move downward and adsorbed on the two parts of the corresponding glass substrate respectively. Since the premise that the glass substrate can move with the conveying plate 2 is that the friction between the glass substrate and the conveying plate 2 can make it move, but it is also possible that the friction between the glass substrate and the conveying plate 2 is not enough to make the glass substrate move with the conveying plate 2. Therefore, the movement of the glass substrate with the conveying plate 2 is a prerequisite for the detection work, and therefore a trigger component is required to identify the movement of the glass substrate and the conveying plate 2 together.

[0032] The two vacuum suction cups 8 and the identification rope 13 are all passed through the through hole 12. The identification rope 13 is in a stretched state in the initial state. In addition, an initial tension value can be set for the tension sensor 14. In this embodiment, it is preferably set to 0. If the tension value detected by the tension sensor 14 during the detection process is greater than the set value, it proves that the two parts of the glass substrate are in relative position and there is a force pulling each other between the two parts of the glass substrate. The first buzzer 17 and the tension sensor 14 are controlled and connected through the PLC controller. The first buzzer 17 sends out an alarm, which means that the two glass substrates have been cut. If the tension sensor 14 detects that the value has not changed, the value of the tension sensor 14 will not change.

[0033] Before the glass substrate is cut, if the conveying plate 2 does not move with the corresponding glass substrate, when the fastening plate 35 moves toward one side of the glass substrate, the buffer ring 37 contacts the glass substrate first, and as the gear 39 continues to rotate, the buffer ring 37 is continuously squeezed and deformed. When the first electromagnet 36 moves to abut against the glass substrate, the identification rod 42 abuts against the proximity switch 46. The proximity switch 46 and the first electromagnet 36 are connected through the control of the PLC controller. The proximity switch 46 controls the first electromagnet 36 to be energized, and the two first electromagnets 36 are attracted to each other, thereby completing the effect of fastening the conveying plate 2 and the corresponding glass substrate.

[0035] The present application discloses a method for laser cutting a glass substrate for display screen processing. Figure 1 A method for laser cutting a glass substrate for display screen processing includes the following method: S1, conveying the glass substrate, conveying the glass substrate to the bottom of the laser cutting device 6 through the conveying plate 2; S2, laser cutting, cutting the glass substrate by rotating the laser cutting device 6; S3, detection, whether the cutting of the glass substrate is completed is detected, and the detection mechanism is used to determine whether the two parts of the glass substrate are separated after the cutting is completed. If they are successfully separated, it proves that the glass substrate has been cut; the two parts of the glass substrate after cutting are adsorbed by two adsorption components respectively, and the identification component is used to identify whether the two parts of the glass substrate are in relative position. If they are in relative position, they are identified by the identification component. Since one part of the glass substrate is located on the conveying plate 2 and the other part is located on the frame 1 during the cutting process, the part of the glass substrate located on the conveying plate 2 is determined by the judgment component to determine whether the conveying plate 2 can drive the part on it to move together. If not, the fastening component is required to fasten the glass substrate to ensure that the glass substrate moves with the conveying plate 2.
