Description

Technical Field

[0001] The present invention relates to the field of laser beam processing, and in particular to an ultrasonic-assisted ultrafast laser glass hole-making device and method. Background Art

[0002] Traditional glass drilling methods have obvious shortcomings. For example, mechanically drilled glass is brittle and hard. When drilling with a glass drill bit, if the operation is improper, such as the feed speed is too fast or the pressure is too high, the glass is easily broken due to local stress concentration. The glass is high in hardness, and the glass drill bit needs to frequently rub against the glass surface during the drilling process. The drill bit wears quickly and needs to be replaced frequently. In order to prevent the glass from breaking, the drilling speed is usually slow, resulting in low overall drilling efficiency. For a large number of drilling tasks, it will consume more time and manpower; water jet processing for cutting glass has problems such as complex process, low precision and surface quality, and the need for a large amount of water and high abrasive costs. Summary of the Invention

[0003] In order to solve the problems that conventional glass hole opening devices currently rely on manpower to increase costs, and at the same time have slow cutting speeds and insufficient processing precision, which lead to reduced cutting quality, the present invention provides an ultrasonic-assisted ultrafast laser glass hole opening device and method.

[0006] A discharge table for placing material sheets is provided in the middle of the material transportation line, a material arrival sensor for sensing the placement status of the material sheets is provided at the front end of the discharge table, an ultrasonic component for performing a sheet removal process on the thinned material sheets is provided on one side of the discharge table in the operating cavity, a lifting component for driving the ultrasonic component to move longitudinally is provided on the side of the ultrasonic component away from the discharge table, a width adjustment component for driving the lifting component to move horizontally and fixed to the main box is provided on the side of the lifting component away from the ultrasonic component, and an auxiliary adjustment wheel for manually adjusting the width adjustment component is provided on one side of the bottom of the width adjustment component.

[0007] By adopting the above technical solution, the material transportation line transports the material sheet to be processed into the operating chamber, and the laser generating device emits laser to cut the material sheet, and the cutting point is still in a tightly connected state. Then the material transportation line transports the preliminarily processed material sheet to the surface of the material discharge table, and then the jacking component drives the fixing component to move to a position flush with the material sheet. The fixing component moves to clamp and fix the material sheet, and then the lifting component and the width adjustment component coordinate to move the ultrasonic component to a position aligned with the cutting point of the material sheet, and the material sheet is delaminated by ultrasonic stamping.

[0008] Preferably, the ultrasonic component includes a mounting shell fixed on one side of the lifting component, a fixed inner shell fixed in the mounting shell, an ultrasonic generator for generating ultrasonic waves fixed in the fixed inner shell, an ultrasonic tool head for transmitting vibration force is telescopically arranged in the fixed inner shell, and a plurality of auxiliary tool heads are arranged around the bottom of the fixed inner shell at the position of the ultrasonic tool head.

[0009] By adopting the above technical solution, the outside of the installation shell is connected to the lifting assembly and the inside is connected to the ultrasonic generator, so that the ultrasonic transmitter can be lifted and moved as a whole. At the same time, the ultrasonic tool head transmits the high-frequency vibration force generated by the ultrasonic generator and contacts the material sheet, thereby processing and separating the laser holes on the surface of the material sheet.

[0010] Preferably, the ultrasonic tool head includes a pressure block telescopically arranged at the bottom of the fixed inner shell, a conduction rod fixed to the ultrasonic generator is inserted through the middle of the pressure block, and a contact surface abutting against the material sheet is fixed at the bottom of the conduction rod, and a plurality of transverse grooves are provided on the surface of the abutment surface around the conduction rod, and expansion plates are movably arranged in the plurality of transverse grooves.

[0011] By adopting the above technical solution, the opening of the transverse groove provides a limiting space for the transverse movement of the expansion board, and at the same time the pressure block is movably connected to the conduction rod, so that the pressure block moves along the conduction rod and drives the expansion board to move.

[0012] Preferably, longitudinal grooves are provided on the surface of the conduction rod at the positions of the multiple transverse grooves, and inclined support rods are movably arranged in the multiple longitudinal grooves. The multiple inclined support rods are rotatably connected to the multiple expansion plates one by one to achieve lateral extension by vibration thrust.

[0013] By adopting the above technical solution, the longitudinal groove provides a slide for the movement of the inclined support rod and limits the movement of the inclined support rod, so that the longitudinal thrust received by the inclined support rod is converted into a lateral thrust, causing the extended plate to move laterally.

[0014] Preferably, an annular groove is formed at the bottom of the pressure block around the through hole of the conduction rod, and an extension torsion spring is fixed in the annular groove. The bottoms of the extension torsion spring are fixedly connected to the tops of the plurality of inclined support rods.

[0015] By adopting the above technical solution, the opening of the annular groove provides a fixed point for the installation of the extension torsion spring. At the same time, the pressure block presses down to push the extension torsion spring downward, so that the extension torsion spring elastically pushes multiple inclined support rods, forming a state in which the top of the inclined support rod moves downward and the bottom of the inclined support rod moves horizontally, thereby driving the expansion plate to move horizontally.

[0016] Preferably, a drop hole is provided on the surface of the discharge table at a position aligned with the ultrasonic component, and a plurality of attenuation holes for improving the efficiency of sound energy transmission are provided on the surface of the discharge table around the drop hole.

[0017] By adopting the above technical solution, the opening of the drop hole provides a discharge outlet for waste materials after the material plate is cut, and at the same time, multiple attenuation holes are arranged around the drop hole, so that the ultrasonic waves received by the discharge table are transmitted and diffused along the multiple drop holes, thereby improving the efficiency of sound energy transmission.

[0018] Preferably, a waste chamber is provided at the bottom of the operating chamber inside the main box body, and a waste transport line for discharging waste residue is provided in the waste chamber.

[0019] By adopting the above technical solution, the waste cavity is connected to the operating cavity, so that the waste dropped from the drop hole falls onto the surface of the waste transport line, and the waste is discharged from the waste cavity to the outside.

[0020] Preferably, both the front and rear ends of the main box are provided with inlet and outlet ports connected to the operating cavity, and the material transportation line extends from the two inlet and outlet ports to the outside.

[0021] By adopting the above technical solution, the inlet and outlet are connected to the operating chamber, thereby reserving an opening for the movement of the material plate in and out. At the same time, the inlet and outlet are connected to the outside to form a semi-sealed state inside the operating chamber, preventing external dust and debris from entering the main shell.

[0022] Preferably, a feeding motor group is provided on one side of the inlet and outlet in the operating chamber, and the output end of the feeding motor group is fixedly connected to the rotating gear in the material transportation line.

[0023] By adopting the above technical solution, the output end of the feeding motor group rotates to drive the material transport line to operate, so that the material transport line drives the material plate to move horizontally, providing power for the moving processing of the material plate.

[0024] An ultrasonic-assisted ultrafast laser glass hole opening method, used in the above-mentioned ultrasonic-assisted ultrafast laser glass hole opening device, comprises the following steps:

[0025] S01, the material transport line drives the material sheet to move from the outside to the operating chamber 2. When the material sheet moves to the bottom of the ultrasonic generator, the ultrasonic generator emits a laser to perform a preliminary cutting on the material sheet, and the thinning work is completed at the cutting point of the material sheet;

[0026] S02. When the sheet moves to the surface of the unloading table, the lifting assembly drives the fixing assembly to move upward until it is aligned with the sheet. The clamping plates in the fixing assembly move toward each other to clamp and fix the sheet. The sheet is fixed to the fixing assembly and abuts against the unloading table.

[0027] S03, the width adjustment assembly drives the lifting assembly 7 to move to a position aligned with the center of the cutting point of the sheet, and the lifting assembly 7 drives the mounting housing to descend, and the mounting housing simultaneously drives the abutment surface to abut against the surface of the sheet, and the ultrasonic generator transmits high-frequency mechanical vibration to the abutment surface through the conduction rod, and the sheet receives the vibration to complete the sheet removal process at the cutting point;

[0028] S04. The downward pressure of the pressure block drives the tops of the multiple inclined support rods to be pressed down synchronously, and the bottoms of the multiple inclined support rods all apply downward pressure to the expansion plate. The multiple expansion plates are laterally limited in the transverse groove. The multiple expansion plates receive the downward pressure of the inclined support rods and convert it into transverse thrust. The multiple expansion plates extend along the transverse groove. After the abutment surface is expanded, it is driven by the installation shell to abut against the material plate, thereby fixing the material plate and improving the stripping effect.

[0029] In summary, the present invention includes at least one of the following beneficial technical effects:

[0030] 1. The material transport line is used to transport the sheet into the operating chamber, where it is initially cut and thinned by the laser generator. Then, as the sheet moves, it is clamped and fixed by the fixing assembly, so that the sheet is stably in contact with the unloading table. The ultrasonic tool head then contacts the cutting point of the sheet, transmitting high-frequency mechanical vibrations to cause the sheet to fall off, thus forming a highly efficient automated operation and improving production efficiency.

[0031] 2. With the help of ultra-fast laser cutting with high speed and no daily consumables, and the ultrasonic device is used to transmit vibration to the cutting point, secondary processing is produced, thereby removing the slices on the glass surface. The process is smooth and the cutting speed is fast. The abutment surface is expanded through the expansion plate, and the coverage range is adjusted as the aperture of the opening increases, so that the ultrasonic stamping coverage range is comprehensive, the processing accuracy is improved, and thus product quality is guaranteed.

[0045] The following is combined with Figures 1-8 The present invention is described in further detail.

[0046] The embodiments of the present invention disclose an ultrasonic-assisted ultrafast laser glass hole-making device and method.

[0047] The "up, down, left, right" viewing angles of this device are Figure 1 The directions in the attached drawings are for reference only.

[0048] Reference Figures 1 to 3, an ultrasonic-assisted ultrafast laser glass hole opening device, comprising a main box body 1, an operating chamber 2 is opened inside the main box body 1, and the outer surface of the main box body 1 is provided with inlet and outlet ports 4 at the front and rear ends of the operating chamber 2, the two inlet and outlet ports 4 are connected with the operating chamber 2, and a material transport line 10 is installed at a position horizontally aligned with the two inlet and outlet ports 4 and the operating chamber 2, the material transport line 10 is used to transport the glass material plate 13 that needs to be processed outside to the inside of the device, and at the same time, a waste chamber 3 is opened at the bottom side of the operating chamber 2 inside the main box body 1, the waste chamber 3 is connected with the operating chamber 2, and the waste chamber 3 and the cavity channel of the operating chamber 2 are in a plane vertically staggered state, a waste transport line 5 is installed in the waste chamber 3, one end of the waste transport line 5 extends to the outside, and a storage device for receiving waste material plates 13 is provided at the end of the extension.

[0049] A width adjustment component 8 is fixedly provided on one side of the top of the material transport line 10 in the operating chamber 2. The width adjustment component 8 is composed of a sliding rod, a slider and a circuit structure driven by air. At the same time, an auxiliary adjustment wheel 9 is provided on one side of the middle part of the base of the width adjustment component 8. The personnel adjusts the sliding distance of the slider of the width adjustment component 8 by rotating the auxiliary adjustment wheel 9. A lifting component 7 is fixedly provided on one side of the slider surface of the width adjustment component 8. The shell of the lifting component 7 is fixedly connected to the slider of the width adjustment component 8 by screws. The telescopic end of the lifting component 7 extends downward, and an ultrasonic component 6 is fixed at the extended end.

[0050] Reference Figures 3 to 5 A discharge table 12 is fixedly provided in the operating chamber 2 at a position between the conveyor belts of the material transport line 10. A drop hole 18 is penetrated through the surface of the discharge table 12 at the position of the ultrasonic component 6. The drop hole 18 is aligned and connected with the waste chamber 3, so that the waste of the cut material plate 13 falls into the waste transport line 5 through the drop hole 18 for recycling. A plurality of attenuation holes 17 are penetrated around the drop hole 18 on the surface of the discharge table 12 to form a porous cavity structure inside the discharge table 12. The porous cavity structure causes the discharge table 12 to reflect, scatter and rub against the pore wall multiple times when receiving high-frequency mechanical vibration, resulting in the conversion of sound energy into heat energy, thereby improving the absorption efficiency.

[0051] At the same time, jacking assemblies 11 are installed on the top of both sides of the material transportation line 10. The telescopic end of the jacking assembly 11 extends upward, and a fixing assembly 15 is provided at the extended end. The fixing assembly 15 consists of a clamping plate abutting the telescopic end of the jacking assembly 11 and a transverse driving mechanism fixedly connected to the clamping plate. Under normal circumstances, the clamping plate of the jacking assembly 11 is horizontally staggered with the material plate 13.

[0052] It should be noted that a feeding motor group 14 is fixedly provided at the end of one side of the material conveying line 10 in the operating chamber 2. The output end of the feeding motor group 14 is fixedly connected to the inside of the material conveying line 10 through a gear. A material arrival sensor 16 is fixedly provided at the front end of the discharge table 12 in the operating chamber 2. The model of the material arrival sensor 16 is the YBLX-ME series limit switch of Chint Electric, and the sensing end of the material arrival sensor 16 is facing the discharge table 12. When a material plate 13 is placed on the surface of the discharge table 12, the material plate 13 contacts the sensing end of the material arrival sensor 16, so that the material sensor 16 transmits an electrical signal. At the same time, a laser generating device 19 is fixedly provided at the end of the operating chamber 2 away from the material arrival sensor 16. The laser emitting end of the laser generating device 19 is facing downwardly towards the material conveying line 10, thereby performing preliminary laser cutting on the material plate 13. The laser generating device 19 uses a wavelength of 1030nm, a single pulse width ≤10ps, and an average power of 0.5-5W.

[0053] Reference Figures 6 to 8 The ultrasonic component 6 includes a mounting shell 61 fixed to the end of the telescopic end of the lifting component 7. The mounting shell 61 is hollow inside and is fixed with a fixed inner shell 62. A groove is opened downward at the top of the fixed inner shell 62, and an ultrasonic generator 65 is fixed in the groove (the ultrasonic generator 65 is set to an output frequency of 20kHz±1kHz, a power of 100-500W, and an adjustable amplitude of 0.1-5μm). The ultrasonic generator 65 is connected to the external power supply equipment through a circuit. A bottom groove is opened on the opposite side of the groove in the fixed inner shell 62, and an ultrasonic tool head 63 is fixed in the bottom groove. The ultrasonic tool head 63 is movable through the bottom groove and connected to the ultrasonic generator 65 in the groove to receive the high-frequency mechanical vibration generated by the ultrasonic generator 65. A plurality of movable and extendable auxiliary tool heads 64 are fixed around the lower end surface of the fixed inner shell 62 around the ultrasonic tool head 63, which are used to abut against the material plate 13 to transmit vibration force and provide auxiliary fixation;

[0054] The ultrasonic tool head 63 includes a pressure block 631 that is movably arranged in the bottom groove of the fixed inner shell 62. One end of the top of the pressure block 631 is movable through the interior of the fixed inner shell 62, and an electric push rod is fixed at the end of the penetration, so that the electric push rod pushes the pressure block 631 to move up and down. At the same time, a through hole is opened in the middle of the pressure block 631, and a conductive rod 632 is movably inserted in the through hole. The conductive rod 632 is movably inserted through the pressure block 631 and is connected to the ultrasonic generator 65. The bottom surface of the conductive rod 632 is fixed with an abutment surface 635. 635 is longitudinally aligned with the center of the opening position of the material plate 13. The surface of the abutment surface 635 is provided with a plurality of transverse grooves 637 surrounding the conductive rod 632. The plurality of transverse grooves 637 are movably inserted into the expansion plates 636. The surface of the conductive rod 632 is provided with longitudinal grooves 638 at the positions of the plurality of transverse grooves 637. The plurality of longitudinal grooves 638 are movably inserted into the plurality of inclined support rods 634. Both ends of the inclined support rods 634 are rotatably connected to the longitudinal grooves 638. The bottoms of the plurality of inclined support rods 634 are rotatably connected to the tops of the plurality of expansion plates 636.

[0055] An annular groove 639 is provided on the lower end surface of the pressure block 631 at the position of the multiple inclined support rods 634, and an extension torsion spring 633 is fixed in the annular groove 639. The extension torsion spring 633 is normally in an extended state, and the calculation formula of the torsion spring elastic force is F=kx, wherein F represents the torsion spring elastic force, represents the torsion spring constant (the magnitude of the elastic force generated by the torsion spring under force per unit length), and x represents the torsion spring compression (referring to the displacement distance of the torsion spring from the original state to the compressed state). The elastic force of the extension torsion spring 633 can be calculated by this formula, and the bottom of the extension torsion spring 633 is fixedly connected to the tops of the multiple inclined support rods 634. When the pressure block 631 is subjected to downward pressure, it is transmitted to the multiple inclined support rods 634 through the extension torsion spring 633, so that the tops of the multiple inclined support rods 634 are simultaneously subjected to downward pressure and then descend.

[0056] It should be noted that multiple expansion plates 636 are engaged and connected with the grooves of the transverse grooves 638, and the connection gap is less than 0.1 mm, and when multiple expansion plates 636 are fully inserted into the transverse grooves 638, the abutment surface 635 is circular as a whole and adapts to the opening of the material plate 13, and the maximum distance that the pressure block 631 is pressed downward is less than the groove length of the transverse groove 638, so that after the pressure block 631 is fully pressed into the stretching torsion spring 633, part of the expansion plate 636 is still located in the transverse groove 638 to prevent excessive movement. The pressure block 631 is combined with the inclined support rod 634 through the pre-tightening spring 633, so that the vibration force is converted into a transverse thrust along the inclined surface, driving the expansion plate 636 to stretch at a uniform speed along the transverse groove 637, thereby maintaining stable clamping during the process of increasing the aperture.

[0057] Among them, the timing of the laser generating device 19 and the ultrasonic generator 65 are controlled by the same PLC. The control logic of this device is: when the signal of the material arrival sensor 16 is confirmed, the PLC issues a sequential control instruction to pause the material transportation line 10, start the jacking component 11-width adjustment component 8-lifting component 7-ultrasonic generator 65, ensuring that each actuator operates in a closed loop according to the timing and speed, and automatically resets after the vibration lasts for 0.5s-2s. The entire process cycle is ≤5s.

[0058] Example 2

[0059] Reference Figures 1 to 8 A method for ultrasonically assisted ultrafast laser glass drilling, used in the above-mentioned ultrasonically assisted ultrafast laser glass drilling device, comprises the following steps:

[0060] S01, the first process is to place the material sheet 13 to be processed on the conveyor surface of the material transport line 10, and then the material transport line 10 is operated to transport the material sheet 13 from one of the inlet and outlet ports 4 to the operating chamber 2. When the material sheet 13 moves to the laser port of the laser generating device 19, the material transport line 10 is paused, and the laser generating device 19 emits a laser to perform a hole cutting on the surface of the material sheet 13. After cutting, the glass is still in a tightly connected state, and the thinning work is completed at the cutting point;

[0061] S02. Then the material transport line 10 continues to transport the preliminarily processed material sheet 13. When the material sheet 13 moves to the surface of the material discharge table 12, the material sheet 13 contacts the sensing end of the material arrival sensor 16, so that the material arrival sensor 16 transmits a signal, causing the material transport line 10 to pause again. At the same time, the jacking component 11 and the fixing component 15 are controlled to operate, and the telescopic end of the jacking component 11 is lifted up, thereby driving the two clamping plates of the fixing component 15 to rise to the turntable aligned with the material sheet 13, and then the two horizontal push rods of the fixing component 15 push toward each other, thereby driving the two clamping plates to move toward each other to clamp and fix the surfaces on both sides of the material sheet 13. At this time, the material sheet 13 is fixed on both sides, and the bottom is in contact with the material discharge table 12.

[0062] S03, and then by moving the slider on the surface of the sliding rod of the rear width adjustment component 8, the shell of the lifting component 7 is driven to move, and the movement of the lifting component 7 synchronously drives the installation shell 61 to move, thereby moving the two ultrasonic tool heads 63 to a position aligned with the center of the cutting point of the material plate 13, and then by moving the telescopic end of the lifting component 7 to extend, the installation shell 61 is driven to move vertically downward. When the bottom of the ultrasonic tool head 63 abuts the surface of the material plate 13, the lifting component 7 stops running. At this time, the ultrasonic tool head 63 is aligned with and abuts the center of the cutting point of the material plate 13, and the ultrasonic generator 65 generates high-frequency mechanical vibration and transmits it to the ultrasonic tool head 63. The ultrasonic tool head 63 abuts the material plate 13 to transmit high-frequency mechanical vibration. The cutting point of the material plate 13 is vibrated, thereby separating the cut part of the material sheet from the main body of the material plate 13, forming a shedding process;

[0063] S04. When the ultrasonic tool head 63 abuts against the surface of the material sheet 13, the personnel controls the pressure block 631 to press down to a corresponding degree according to the different cutting diameters of the material sheet 13. The pressure block 631 applies synchronous pressure to the multiple inclined support rods 634, so that the tops of the multiple inclined support rods 634 move downward along the longitudinal groove 638, and the bottoms of the inclined support rods 634 are connected to the expansion plate 636. The inclined support rods 634 transfer the downward thrust they receive to the expansion plate 636, so that the expansion plate 636 moves laterally along the transverse groove 637 and expands outward, thereby expanding the coverage of the abutment surface 635 as a whole. As the abutment surface 635 abuts against the material sheet 13, the fixing effect on the material sheet 13 is increased, and at the same time, the output range of the high-frequency mechanical vibration is expanded, thereby improving the sheet removal effect.

[0064] The above are merely optional embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.

The material sheet is fixed to the fixing assembly and abuts against the material discharge table. S02, the width adjustment assembly drives the lifting assembly to move to a position aligned with the center of the cutting point of the sheet, the lifting assembly drives the mounting housing to descend, and the mounting housing simultaneously drives the abutment surface to abut against the surface of the sheet, the ultrasonic generator transmits high-frequency mechanical vibration to the abutment surface through the conduction rod, and the sheet receives the vibration to complete the sheet removal process at the cutting point; S03. The downward pressure of the pressure block drives the tops of the multiple inclined support rods to be pressed down synchronously, and the bottoms of the multiple inclined support rods all apply downward pressure to the expansion plate. The multiple expansion plates are laterally limited in the transverse grooves. The multiple expansion plates receive the downward pressure of the inclined support rods and convert it into transverse thrust. The multiple expansion plates extend along the transverse grooves. After the abutment surface is expanded, it is driven by the mounting shell to abut against the material plate, thereby fixing the material plate and improving the stripping effect.
