Description

Technical Field

[0001] This invention relates to the field of display panel substrate cutting and processing technology, and in particular to a display panel substrate cutting waste processing mechanism and laser cutting equipment. Background Technology

[0002] In the manufacturing process of mobile phone display substrates, irregular features such as rounded corners on the glass substrate generally need to be laser-cut. Currently, the mainstream processing method is precision laser cutting. After cutting, waste material is generated and needs to be disposed of to prevent it from affecting subsequent processes.

[0003] Because the glass substrate of mobile phone display is thin and light, the waste from cutting rounded corners is even lighter. After cutting, the waste is not easy to fall off and will stick together, so it needs to be separated. At present, the waste generated from cutting glass substrate mainly relies on airflow blowing and suction system. That is, a high-pressure air nozzle is set next to the laser cutting head. After cutting, high-pressure compressed air is sprayed vertically downwards to blow the waste away from the substrate. At the same time, the hollowed-out jig below works with the negative pressure pipe to suck away the waste.

[0004] However, when processing ultra-thin glass or some flexible substrates, relying solely on high-pressure airflow blown vertically downwards can cause tensile stress on the edges of the waste material that is still attached to the glass substrate, leading to edge chipping or microcracks. Furthermore, when there is slag adhering between the waste material and the substrate, the impact force of a simple vertical airflow is insufficient to reliably remove the waste material. Therefore, achieving low-damage and high-reliability separation of the waste material from the substrate is a pressing issue that needs to be addressed. Summary of the Invention

[0005] The purpose of this invention is to provide a waste processing mechanism and laser cutting equipment for display screen substrate cutting, so as to solve the technical problem in the prior art that the waste material of the display screen glass substrate is not easy to reliably separate from the substrate body after cutting.

[0006] The technical problem to be solved by this invention can be achieved through the following technical solution: A display substrate cutting waste processing mechanism includes an air blowing de-materializing mechanism and a receiving base box. The receiving base box is disposed at the bottom of the mold table. The air blowing de-materializing mechanism includes a lifting drive mechanism, an air pump, and an air vibration mechanism. The air vibration mechanism includes a pneumatic lateral vibration mechanism and an airflow impact mechanism. The lifting drive mechanism is used to drive the pneumatic lateral vibration mechanism to descend and contact the waste material at the edge cutting position of the glass substrate. The air pump is used to deliver airflow to the pneumatic lateral vibration mechanism. The pneumatic lateral vibration mechanism generates lateral vibration by relying on the airflow delivered by the air pump and acts on the contacting waste material. After the pneumatic lateral vibration mechanism generates vibration on the waste material for a set duration, the airflow impact mechanism is used to blow the airflow generated by the air pump directly vertically downward toward the glass substrate cutting position.

[0007] Preferably, the air-blowing material removal mechanism further includes a lifting and positioning frame, which is connected to the drive end of the lifting drive mechanism. A pressure-sensing switch electrically connected to the air pump is provided at the bottom of the lifting and positioning frame. Multiple sets of pneumatic lateral vibration mechanisms and airflow impact mechanisms are provided and distributed on the edge of the lifting and positioning frame. Each set of pneumatic lateral vibration mechanisms includes a mounting box, a vibrating plate, and a pneumatic mechanism. The mounting box is connected to the lifting and positioning frame. The vibrating plate is attached to the bottom of the mounting box. An air inlet pipe is connected to one side of the mounting box, and an air outlet pipe is connected to the other side. The mounting box is connected to the air outlet of the air pump through the air inlet pipe. The pneumatic mechanism is located inside the mounting box, and the pneumatic mechanism drives the vibrating plate to reciprocate laterally under the action of the airflow generated by the air pump.

[0008] Preferably, the pneumatic mechanism includes a central shaft, fan blades, a cam, and a linkage stop. The central shaft is rotatably connected inside the mounting box. Multiple fan blades are provided and are circumferentially and equidistantly fixed to the central shaft. The fan blades are positioned in the airflow path between the inlet pipe and the outlet pipe. The cam is coaxially and fixedly connected to the central shaft. The linkage stop is connected to the vibrating plate. A first guide rod is laterally fixed inside the mounting box and passes laterally through the linkage stop. A first spring connects the linkage stop and the first guide rod. Preferably, each set of pneumatic lateral vibration mechanisms and lifting positioning frames are laterally slidably connected, and each set of pneumatic lateral vibration mechanisms and lifting positioning frames is also connected to a sliding drive mechanism. One side of the airflow impact mechanism is fixedly connected to the air inlet pipe, and the other side is connected to the air outlet of the air pump through a metal hose.

[0009] Preferably, the sliding drive mechanism includes a second guide rod, a linkage sleeve, and a linkage rod. The second guide rod is vertically fixedly connected to the lifting positioning frame. The linkage sleeve is slidably sleeved on the second guide rod, and a second spring is connected between the linkage sleeve and the second guide rod. One end of the linkage rod is movably connected to the mounting box via a hinge, and the other end is movably connected to the linkage sleeve via a hinge. The lifting drive mechanism includes a pressure sleeve for pressing down the linkage sleeve. Preferably, the lifting drive mechanism further includes an electric telescopic rod, a sliding crossbeam, and an elastic connector. The electric telescopic rod is vertically fixedly connected to the bottom of the sliding crossbeam, and the telescopic end of the electric telescopic rod is connected to the lifting positioning frame through the elastic connector. The pressure sleeve is fixedly connected to the telescopic end of the electric telescopic rod.

[0010] Preferably, the elastic connector includes a third guide rod and a connecting sleeve. The third guide rod is vertically fixedly connected to the lifting positioning frame, and the connecting sleeve is slidably sleeved on the third guide rod. A third spring is also connected between the connecting sleeve and the third guide rod. The connecting sleeve is fixedly connected to the telescopic end of the electric telescopic rod.

[0011] Preferably, the air-blowing material removal mechanism further includes a lifting and limiting mechanism, which includes a limiting frame and a stop block. The limiting frame is fixedly disposed relative to the sliding crossbeam, and the stop block is fixedly connected to the top of the third guide rod. The limiting frame is aligned below the stop block. When the lifting and positioning frame descends and adheres to the glass substrate, the stop block adheres to the limiting frame.

[0012] Preferably, the airflow impact mechanism includes a transition box, a reversing valve plate, and a bottom tube. One side of the transition box is fixedly connected to the air inlet pipe, and the other side is connected to the air outlet of the air pump. The bottom tube is located at the bottom of the transition box. The reversing valve plate is rotatably located inside the transition box. A gear coaxially connected to the reversing valve plate is provided on the outside of the transition box. A rack that meshes with the gear is horizontally fixedly connected to the lifting positioning frame.

[0013] The beneficial effects of this invention are: 1. This invention uses a pneumatic lateral vibration mechanism to contact the waste material at the rounded corner cutting position of the glass substrate under the action of air source provided by the air pump. The waste material is loosened by lateral vibration, so that the connection point between the waste material and the glass substrate is subjected to pure shear, avoiding edge cracking. After the vibration is applied for a set time, the waste material is impacted by the airflow impact mechanism, which effectively ensures the reliable removal and separation of waste material.

[0014] 2. This invention relies on a lifting positioning frame to drive distributed pneumatic lateral vibration mechanisms to descend and contact the various edge cutting positions on the glass substrate. The vibrating plates of each set of pneumatic lateral vibration mechanisms are in contact with the waste material that has not been detached. The strong airflow provided by the air pump enters the mounting box of each pneumatic lateral vibration mechanism through the air inlet pipe and acts on the fan blades. The fan blade drives the cam to rotate, and the cam continuously acts on the set linkage block. Under the action of the spring rebound force, the vibrating plate can move laterally back and forth, so that the waste material in contact is subjected to lateral back and forth force.

[0015] 3. In this invention, the electric telescopic rod drives the lifting and positioning frame to lower the distributed pneumatic lateral drive mechanism to the position where it contacts the glass substrate cutting waste. After the electric telescopic rod continues to extend, it drives the set pressure sleeve to descend and squeeze the linkage sleeve. The linkage sleeve then slides down and pushes the pneumatic lateral vibration mechanism to move laterally above the waste through the linkage rod. At the same time, the set airflow impact mechanism moves synchronously and switches to above the waste. During this process, the airflow impact mechanism uses the cooperation of gears and racks to make the internal reversing valve plate rotate, blocking the air path to the pneumatic lateral vibration mechanism and opening the downward-facing bottom pipe. This allows the airflow generated by the air pump to be concentrated and sprayed vertically downward from the bottom pipe, ensuring that the waste loosened by vibration falls into the collection box.

[0016] 4. When the lifting and positioning frame of this invention is driven by an electric telescopic rod to descend and fit against the glass substrate on the mold table, the stop block fixedly set relative to the lifting and positioning frame fits precisely against the set limit stop frame. The limit stop frame is fixed in position relative to the sliding crossbeam, effectively limiting the downward squeezing force of the lifting and positioning frame. This avoids the elastic connector from compressing and generating a rebound force during the continuous extension of the electric telescopic rod, which would increase the downward force of the lifting and positioning frame, causing the contacted glass substrate to be crushed and the vibrating plate to be excessively pressed on the waste material that has not been detached, causing the connection point between the waste material and the main body of the glass substrate to be subjected to hard pressure, resulting in edge chipping.

[0019] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0020] like Figures 1 to 13As shown, a waste processing mechanism for display substrate cutting is used to process waste generated from the rounded corner cutting of mobile phone display glass substrates. This waste processing mechanism is installed inside a laser cutting equipment and specifically includes an air-blowing material removal mechanism 3 and a receiving base box 5. The receiving base box 5 is set at the bottom of a mold table 2, which is fixedly installed within the frame 1 of the laser cutting equipment. The mold table 2 is used to hold the glass substrate 6, and it has densely distributed micro-holes connected to a negative pressure device to generate negative pressure, firmly adsorbing the glass substrate 6 onto the surface of the mold table 2. The laser cutting equipment can be equipped with a robotic arm with suction cups. The robotic arm drives the suction cups to pick up the glass substrate 6, then transfers it and precisely places it on the surface of the mold table 2. The size of the mold table 2 matches the size and shape of the glass substrate 6 to be cut, and corresponding positions have hollow structures to facilitate the falling of cut waste into the receiving base box 5. For example, when rounding the corners of the glass substrate 6, the corners of the mold table 2 are hollowed out. See reference for details. Figure 3 The structure of the mold platform 2 shown.

[0021] To effectively separate the waste material generated from the rounded corner cutting of the glass substrate 6 without causing excessive vertical impact force on the edge of the glass substrate 6 and resulting in breakage, the air-blowing material removal mechanism 3 includes a lifting drive mechanism, an air pump 35, and an air vibration mechanism 38. The air vibration mechanism 38 includes a pneumatic lateral vibration mechanism 381 and an airflow impact mechanism 386. The lifting drive mechanism drives the pneumatic lateral vibration mechanism 381 to descend and contact the waste material at the edge cutting position of the glass substrate 6. The air pump 35 supplies airflow to the pneumatic lateral vibration mechanism 381. The pneumatic lateral vibration mechanism 381 generates lateral vibration based on the airflow supplied by the air pump 35 and acts on the contacted waste material, facilitating the separation of the waste material from the glass substrate 6 through lateral vibration. During lateral vibration, the connection point bears pure shear. When cut, the fracture surface is flat and will not induce edge cracking. However, during longitudinal vibration, the waste material moves up and down, and the connection point is subjected to bending or axial tension similar to a cantilever beam. The stress is concentrated at the junction of the connection point and the glass substrate 6 body, which is very easy to generate tensile stress on the glass substrate 6 body. Glass is extremely sensitive to tensile stress and is prone to edge cracking and cracking under longitudinal vibration. Therefore, transverse vibration is more effective. Multiple sets of pneumatic transverse vibration mechanism 381 can be set to contact waste material at different positions. After the pneumatic transverse vibration mechanism 381 vibrates the waste material for a set time, the airflow impact mechanism 386 is used to blow the airflow generated by the air pump 35 directly vertically downward to the cutting position of the glass substrate 6 to ensure that the waste material is effectively separated and falls into the receiving box 5.

[0022] In some specific implementation schemes, refer to Figure 5 and Figure 6As shown, the air-blowing material removal mechanism 3 also includes a lifting and positioning frame 33, which is connected to the drive end of the lifting drive mechanism. The lifting and positioning frame 33 is used to move above the mold table 2 and align it. A pressure sensing switch electrically connected to the air pump 35 is provided at the bottom of the lifting and positioning frame 33. That is, when the lifting and positioning frame 33 presses against the glass substrate 6 on the mold table 2, the pressure sensing switch will generate a sense, causing the air pump 35 to run. Multiple sets of pneumatic transverse vibration mechanism 381 and airflow impact mechanism 386 are provided and distributed at corresponding positions on the edge of the lifting and positioning frame 33. Each set of pneumatic transverse vibration mechanism 381 includes a mounting box 3811, a vibrating plate 3812 and a pneumatic mechanism. The mounting box 3811 is connected to the lifting and positioning frame 33, and the bottom of the mounting box 3811 is... The mounting box 3811 has an open section, and the vibrating plate 3812 is fitted to the bottom of the mounting box 3811. The vibrating plate 3812 needs to move laterally back and forth relative to the bottom of the mounting box 3811. Therefore, the upper layer of the vibrating plate 3812 is a smooth metal sheet for direct contact with the bottom of the mounting box 3811, and the lower layer is an elastic rubber sheet for contact with glass waste. One side of the mounting box 3811 is connected to an air inlet pipe 3813, and the other side is connected to an air outlet pipe 3814. The air inlet pipe 3813 and the air outlet pipe 3814 are laterally aligned and have the same diameter. The mounting box 3811 is connected to the air outlet of the air pump 35 through the air inlet pipe 3813. The pneumatic mechanism is located inside the mounting box 3811, and the pneumatic mechanism drives the vibrating plate 3812 to vibrate laterally back and forth under the action of the airflow generated by the air pump 35. It should be noted that, since the glass substrate 6 of the mobile phone display screen is thin and light, the waste material from the rounded corner cutting is even lighter and is not easy to fall off after cutting. This solution is to assist the safe removal of the waste material that has not fallen off.

[0023] Among them, reference Figure 8As shown, the pneumatic mechanism includes a central shaft 3816, fan blades 3815, a cam 3819, and a linkage stop block 3817. The central shaft 3816 is rotatably connected within the mounting box 3811 and is positioned in a front-to-back orientation. Multiple fan blades 3815 are provided and are circumferentially and equidistantly fixed to the central shaft 3816. The fan blades 3815 are positioned in the airflow path between the inlet pipe 3813 and the outlet pipe 3814. Specifically, the fan blades 3815 positioned slightly above the central shaft 3816 are positioned in the airflow path, facilitating the action of high-pressure airflow, which causes the central shaft 3816 to rotate. Wheel 3819 is coaxially fixedly connected to central shaft 3816. Linkage block 3817 is connected to vibrating plate 3812, and linkage block 3817 is positioned on the rotation trajectory of cam 3819. A first guide rod 3818 is horizontally fixedly connected inside mounting box 3811, and the first guide rod 3818 horizontally passes through linkage block 3817. Linkage block 3817 can slide relative to the first guide rod 3818. A first spring is connected between linkage block 3817 and first guide rod 3818. It should be noted that linkage block 3817 can be staggered with the distributed fan blades 3815 to prevent motion interference between the two. When the airflow generated by the air pump 35 enters through the inlet pipe 3813 and exits through the outlet pipe 3814, the high-pressure airflow acts on the distributed fan blades 3815, causing the fan blades 3815 to drive the central shaft 3816 to rotate. The central shaft 3816 then causes the cam 3819 to rotate. When the cam 3819 rotates past the linkage stop 3817, it pushes the linkage stop 3817, causing it to slide laterally a certain distance along the first guide rod 3818. During this process, the first spring deforms and generates a rebound force. When the cam 3819 rotates to a certain position, it separates from the linkage stop 3817, and the linkage stop 3817 resets due to the rebound force of the first spring. Since the linkage stop 3817 is connected to the vibrating plate 3812, it can drive the vibrating plate 3812 to vibrate laterally and reciprocate, which facilitates the generation of a lateral force on the contacted waste material, making it loose and easy to fall off.

[0024] In some specific implementations, to prevent small fragments from splashing into surrounding equipment or onto the glass substrate 6 during the vibration of the vibrating plate 3812 in contact with waste material, refer to... Figure 7 As shown, an annular tube 382 is provided on the outside of the mounting box 3811. The coverage area of ​​the annular tube 382 is larger than the area of ​​the cutting waste at the corresponding edge position of the glass substrate 6. The vent pipe 3814 is connected to the annular tube 382. Multiple exhaust holes 3821 are evenly distributed at the bottom of the annular tube 382. The airflow discharged from the vent pipe 3814 enters the annular tube 382 and then is discharged downward through the exhaust holes 3821, forming a ring of air curtain, which effectively blocks the boundary of the waste subjected to vibration.

[0025] In some specific implementations, to facilitate effective switching between the positions of the airflow impact mechanism 386 and the pneumatic lateral vibration mechanism 381, refer to Figure 5 and Figure 6 As shown, each set of pneumatic lateral vibration mechanisms 381 is laterally slidably connected to the lifting and positioning frame 33. Specifically, a guide rail can be horizontally fixedly installed on the lifting and positioning frame 33, so that the mounting box 3811 is slidably connected to the guide rail. Alternatively, a square rod can be fixedly connected to one side of the annular tube 382, ​​and the square rod slides through the side wall of the lifting and positioning frame 33. A sliding drive mechanism is also connected between each set of pneumatic lateral vibration mechanisms 381 and the lifting and positioning frame 33. One side of the airflow impact mechanism 386 is fixedly connected to the air inlet pipe 3813, and the other side is connected to the air outlet of the air pump 35 through a metal hose or corrugated telescopic pipe.

[0026] The sliding drive mechanism includes a second guide rod 385, a linkage sleeve 384, and a linkage rod 383. The second guide rod 385 is vertically fixedly connected to the lifting positioning frame 33. The linkage sleeve 384 is slidably sleeved on the second guide rod 385, and a compressible second spring is connected between the linkage sleeve 384 and the second guide rod 385. One end of the linkage rod 383 is movably connected to the mounting box 3811 via a hinge, and the other end is movably connected to the linkage sleeve 384 via a hinge. The lifting drive mechanism includes a pressure sleeve 387 for pressing down the linkage sleeve 384, and the pressure sleeve 387 is aligned above the linkage sleeve 384. The lifting drive mechanism also includes an electric telescopic rod 32, a sliding beam 31, and an elastic connector. The sliding beam 31 is laterally slidably installed inside the laser cutting equipment. Specifically, a transverse drive rail can be installed on the laser cutting equipment. The sliding beam 31 is slidably connected to the transverse drive rail. The electric telescopic rod 32 is vertically fixedly connected to the bottom of the sliding beam 31, with the telescopic end of the electric telescopic rod 32 facing downwards. The telescopic end of the electric telescopic rod 32 is connected to the lifting positioning frame 33 through the elastic connector. The pressure sleeve 387 is fixedly connected to the telescopic end of the electric telescopic rod 32 through a bracket, and there is a certain gap between the pressure sleeve 387 and the linkage sleeve 384 at the initial position.

[0027] When it is necessary to effectively remove the waste material from the rounded corners of the glass substrate 6 cut on the mold table 2, the equipment control program operates to move the sliding beam 31 to the top of the mold table 2, and the distributed pneumatic lateral vibration mechanism 381 is positioned directly above the corresponding cutting position. After reaching the position, the sliding beam 31 is precisely positioned and stopped by the limit switch and photoelectric switch on the laser cutting equipment. Then, the electric telescopic rod 32 is triggered to extend downward. The electric telescopic rod 32 then drives the distributed pneumatic lateral vibration mechanism 381 to descend through the lifting and positioning frame 33. During this process, due to the presence of the elastic connector, the relative position between the pressure sleeve 387 and the linkage sleeve 384 remains unchanged. When the lifting and positioning frame 33 descends and contacts the glass substrate 6 on the mold table 2, the pressure sensor switch is activated, causing the air pump 35 to run and generate a strong airflow to the position of each pneumatic lateral vibration mechanism 381. At the same time, the vibration plate 3812 of each group of pneumatic lateral vibration mechanisms 381 contacts the waste material at the corresponding position, and then generates a lateral vibration effect. As the electric telescopic rod 32 continues to extend, the elastic connector is compressed, and the pressure sleeve 387 descends and gradually approaches the linkage sleeve 384. When the pressure sleeve 387 descends to the position of the linkage sleeve 384, the pressure sleeve 387 pushes the linkage sleeve 384, and the linkage sleeve 384 descends along the second guide rod 385 to compress the second spring. The linkage sleeve 384 also pushes the mounting box 3811 of the pneumatic transverse vibration mechanism 381 laterally through the linkage rod 383. The mounting box 3811 then slides laterally away from the lifting positioning frame 33. During this process, the airflow impact mechanism 386 moves laterally and moves above the waste position. Then, the airflow impact mechanism 386 directly concentrates the airflow generated by the air pump 35 downward to ensure that the waste effectively falls to the bottom.

[0028] It should be noted that, in order to facilitate the simultaneous distribution of the airflow generated by the air pump 35 to each pneumatic lateral vibration mechanism 381, a main pipe 39 is fixedly connected in the middle of the lifting and positioning frame 33. The airflow impact mechanism 386 corresponding to each group of pneumatic lateral vibration mechanisms 381 is connected to the main pipe 39 through a metal hose or a corrugated expansion tube. The main pipe 39 is also connected to the air outlet of the air pump 35 through a metal hose or a corrugated expansion tube.

[0029] The elastic connector includes a third guide rod 34 and a connecting sleeve 36. The third guide rod 34 is vertically fixedly connected to the lifting positioning frame 33. Specifically, two rods can be symmetrically arranged on the left and right. The connecting sleeve 36 is slidably sleeved on the third guide rod 34. A compressible third spring is also connected between the connecting sleeve 36 and the third guide rod 34. The connecting sleeve 36 is fixedly connected to the telescopic end of the electric telescopic rod 32 through a bracket.

[0030] In some specific implementations, the elastic connector generates a rebound force when compressed, increasing the downward force of the lifting positioning frame 33. This is to prevent damage to the contacting glass substrate 6, and also to prevent the vibrating plate 3812 from excessively pressing on the unremoved waste material, causing hard pressure on the connection point between the waste material and the main body of the glass substrate 6, resulting in edge chipping. The air blowing material removal mechanism 3 also includes a lifting limit mechanism 37, which includes a limit stop frame 371 and a stop block 375. The limit stop frame 371 is fixedly set relative to the sliding crossbeam 31, and the stop block 375 is fixedly connected to the top of the third guide rod 34, with the limit stop frame 371 aligned with the top of the sliding crossbeam 31. Below the stop block 375, when the lifting positioning frame 33 descends and adheres to the glass substrate 6, the pressure generated by the contact is just enough to trigger the air pump 35. The stop block 375 adheres to the limiting frame 371. Thus, even if the connecting sleeve 36 descends along the third guide rod 34 and compresses the third spring, the rebound force generated by the third spring acts on the lifting positioning frame 33. Since the limiting frame 371 blocks the stop block 375, and the relative positions of the stop block 375, the third guide rod 34, and the lifting positioning frame 33 are fixed, the lifting positioning frame 33 can be prevented from excessively squeezing the glass substrate 6, and the vibrating plate 3812 can also be prevented from excessively squeezing the undislodged waste material position.

[0031] In addition, to facilitate control of the contact degree between the lifting positioning frame 33 and the glass substrate 6, as well as the contact degree between the vibrating plate 3812 and the unshed waste material, the lifting limit mechanism 37 also includes a vertical rod 374 and an adjusting screw 372. The vertical rod 374 is vertically fixedly connected to the bottom of the sliding beam 31, and a fixing block 373 is fixedly connected to the vertical rod 374. The adjusting screw 372 is threadedly connected to the fixing block 373, and the bottom end of the adjusting screw 372 is rotatably connected to the limit stop frame 371. The vertical rod 374 also passes through one side of the limit stop frame 371, and the limit stop frame 371 can slide relative to the vertical rod 374. The initial distance between the limit stop frame 371 and the stop block 375 can be adjusted by adjusting the adjusting screw 372, thus limiting the distance that the stop block 375 and the relatively fixed lifting positioning frame 33 can descend.

[0032] In some specific implementations, to facilitate the switching of the airflow impact mechanism 386 on the waste material, the airflow can be concentrated on the waste material below, as per reference. Figure 8 and Figure 10As shown, the airflow impact mechanism 386 includes a transition box 3861, a reversing valve plate 3863, and a bottom tube 3862. One side of the transition box 3861 is fixedly connected to the air inlet pipe 3813, and the other side is connected to the air outlet of the air pump 35. The bottom tube 3862 is located at the bottom of the transition box 3861. The reversing valve plate 3863 is rotatably located inside the transition box 3861 via a rotating shaft. When the pneumatic transverse vibration mechanism 381 is above the cutting waste, the reversing valve plate 3863 blocks the bottom tube 3862. A gear 3864 coaxially connected to the reversing valve plate 3863 is provided on the outside of the transition box 3861. The horizontal lifting positioning frame 33 is horizontally positioned above the gear 3861. A rack 3865 is fixedly connected to the gear 3864. When the airflow impact mechanism 386 and the corresponding pneumatic lateral vibration mechanism 381 move laterally in sync, and the airflow impact mechanism 386 moves above the position of the cutting waste, the gear 3864 rolls along the rack 3865. The gear 3864 then drives the reversing valve plate 3863 to rotate synchronously. The reversing valve plate 3863 then blocks the connection between the transition box 3861 and the air inlet pipe 3813 and opens the position of the bottom pipe 3862. In this way, the airflow delivered by the air pump 35 is sprayed downward through the bottom pipe 3862 and concentrated on the position of the cutting waste below.

[0033] A laser cutting device may include any of the above embodiments, and also includes a laser cutting component 4. The laser cutting component 4 is disposed in the frame 1. The laser cutting component 4 includes a laser emitting head and a three-dimensional guide rail assembly for driving the laser emitting head to move. The three-dimensional guide rail assembly may include a guide rail for driving in the front-back direction, a guide rail for driving in the left-right direction, and a guide rail for driving up and down. It is used to control the laser cutting component 4 to adjust its position for cutting, and to facilitate the repositioning after cutting, so that the air blowing material removal mechanism 3 can move to the top of the mold table 2 for waste disposal.

[0034] To facilitate understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution will now be briefly explained in conjunction with specific application scenarios: First, a robotic arm with suction cups picks up the glass substrate 6 that needs to be rounded at the edges and places it on the mold table 2. The mold table 2 has micro-holes densely distributed on it. The micro-holes are connected to a negative pressure device to generate negative pressure and firmly adsorb the glass substrate 6 onto the surface of the mold table 2. Then, the laser cutting component 4 moves closer to the glass substrate 6 according to the program settings and performs rounded corner cutting on its edges using a laser.

[0035] After laser cutting, the sliding beam 31 moves the lifting positioning frame 33 to the top of the mold table 2 through the equipment control program. At this time, the distributed pneumatic transverse vibration mechanism 381 is positioned directly above the corresponding cutting position. When the sliding beam 31 stops at the precise position, the electric telescopic rod 32 is activated to extend downward. The electric telescopic rod 32 then drives the distributed pneumatic transverse vibration mechanism 381 to descend through the lifting positioning frame 33. During this process, due to the presence of the elastic connecting piece, the relative position between the pressure sleeve 387 and the linkage sleeve 384 remains unchanged. When the lifting positioning frame 33 descends and contacts the glass substrate 6 on the mold table 2, the pressure sensing switch is activated, causing the air pump 35 to run and generate a strong airflow to the location of each group of pneumatic transverse vibration mechanism 381. The vibration plate 3812 corresponding to each group of pneumatic transverse vibration mechanism 381 contacts the corresponding cutting waste position. In addition, since the stop block 375 is attached to the limit frame 371, it prevents the lifting positioning frame 33 from excessively squeezing the glass substrate 6, and also avoids the vibration plate 3812 from excessively squeezing the waste position that has not been detached. When the high-pressure airflow delivered to the location of each pneumatic lateral vibration mechanism 381 enters the corresponding mounting box 3811, the airflow enters from the inlet pipe 3813 and exits from the outlet pipe 3814. The high-pressure airflow acts on the distributed fan blades 3815, causing the fan blades 3815 to drive the central shaft 3816 to rotate. The central shaft 3816 then causes the cam 3819 to rotate. When the cam 3819 rotates past the linkage stop 3817, it pushes the linkage stop 3817, causing it to slide laterally a certain distance along the first guide rod 3818. During this process, the first spring deforms. The cam 3819 generates a rebound force, and when it rotates to a certain position, it separates from the linkage stop 3817. The linkage stop 3817 then resets due to the rebound force of the first spring. Since the linkage stop 3817 is connected to the vibrating plate 3812, it can drive the vibrating plate 3812 to vibrate laterally and reciprocate, which facilitates the generation of lateral force on the contacting waste material, making it loose and easy to fall off. Furthermore, the airflow discharged from the exhaust pipe 3814 enters the annular pipe 382 and then exits downward through the exhaust port 3821, forming a ring of air curtain, which effectively blocks the boundary of the waste material subjected to vibration. During the process of the vibrating plate 3812 contacting the undisturbed waste material for lateral vibration-assisted detachment, the electric telescopic rod 32 continuously extends, the elastic connector compresses, and the pressure sleeve 387 descends and gradually approaches the linkage sleeve 384. When the pressure sleeve 387 descends to the position of the linkage sleeve 384, it pushes against the linkage sleeve 384. The linkage sleeve 384 then descends along the second guide rod 385, compressing the second spring. Furthermore, the linkage sleeve 384 laterally pushes against the mounting box 3811 of the pneumatic lateral vibration mechanism 381 via the linkage rod 383. The mounting box 3811 then slides laterally away from the lifting and positioning frame 33. Position frame 33, during this process, airflow impact mechanism 386 moves horizontally and moves above the waste material position; when airflow impact mechanism 386 moves above the waste material cutting position, gear 3864 rolls along rack 3865, gear 3864 drives reversing valve plate 3863 to rotate synchronously, reversing valve plate 3863 blocks the connection between transition box 3861 and air inlet pipe 3813 and opens the position of bottom pipe 3862, so that the airflow delivered by air pump 35 is sprayed downward through bottom pipe 3862, concentrating on the position of cutting waste material below, effectively ensuring that waste material falls into the receiving bottom box 5.

[0036] The above-disclosed embodiments are merely a few specific examples of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
