Description

Technical Field

[0001] This invention belongs to the field of glass and high-precision processing technology, and in particular relates to a multi-angle automated glass drilling and laser cutting machine. Background Technology

[0002] Laser glass cutting technology is mainly divided into melting cutting, crack control cutting, and stealth cutting based on its principle. Among them, multi-angle automated laser cutting machines usually integrate a high-precision motion control system, a laser generator, a beam transmission and focusing system, a vision positioning system, and a cooling and dust removal system.

[0003] When a laser drills or cuts in glass, it generates extremely high local instantaneous temperatures. Although glass itself has poor thermal conductivity, the accumulation of heat can still lead to uneven distribution of thermal stress, causing uncontrollable propagation of microcracks, resulting in chipping, gaps, or overall cracking of the glass. To address this, existing equipment typically uses a side-blowing air curtain to blow away dust generated during processing, preventing dust from contaminating the lens and adhering to the processing surface, thus affecting laser energy transmission. It also provides some cooling to the processing area.

[0004] However, this type of laser cutting machine has significant drawbacks during use: 1. The airflow field is unstable, making it difficult to form a uniformly covered cooling layer on non-planar multi-angle processing surfaces. For inclined drilling, the cooling effect on the leeward side is poor, resulting in inconsistent cooling rates on both sides of the glass and generating asymmetrical thermal stress. This can easily cause additional cracks in brittle glass, seriously affecting processing quality and yield.

[0005] 2. The direction of gravity is completely consistent with the cutting direction and the debris discharge path. The material melted and vaporized by the laser, as well as the generated tiny particles, can fall naturally downwards with the help of gravity and leave the cut. However, when performing angled cutting, the debris needs to overcome this positive pressure and the huge static friction force generated thereafter to be discharged. This greatly increases the difficulty of discharge. These retained melts will re-solidify and adhere to the cut wall, forming slag and severely deteriorating the cutting quality. Summary of the Invention

[0006] The purpose of this invention is to overcome the problems of unstable flow field, uneven cooling layer coverage, easy generation of thermal stress leading to glass cracks during multi-angle processing in the prior art, and difficulty in removing debris during tilt cutting, resulting in molten material solidifying and forming slag, which affects the cutting quality.

The nozzle direction forms a 45° angle with the atomizing spray direction of the atomizer. An angle-adjustable component is disposed on the side of the rotating ring and is connected to the cooling component for driving the cooling component to rotate to different angles.

[0009] Furthermore, the nozzle has a plate-like structure, and each group of nozzles is arranged vertically at an inclination along the centripetal direction of the fixing ring.

[0010] Furthermore, the chip removal assembly includes: Multiple collars are provided, and the diameter of each group of collars gradually increases radially. The gap between each group of collars forms a debris channel. The top of each group of collars is installed in the hollow of the fixed ring, and the bottom of each group of collars passes through the rotating ring. The fixed ring has symmetrically arranged debris grooves inside, which are connected to the air extraction port. The debris channel corresponds to the debris groove. The connecting block is plate-shaped and is arranged and fixedly installed between each set of collars along the circumferential direction; An air extraction port is installed on one side of the laser port and connected to an external air pump; Inner ring, which is fitted onto the bottom wall of the rotating ring; Two baffles are provided, and the two baffles are symmetrically installed at the left and right ends of the inner ring to block the gaps between multiple sets of collars, so as to improve the negative pressure capacity of the collars. The baffles are located inside the rotating ring.

[0011] Furthermore, a hollow outer ring component is fixedly installed at the bottom of the rotating ring, and the baffle plate is fixedly connected to the top of the inner ring of the outer ring component. The inner side of the outer ring component is arranged in a conical structure.

[0012] Furthermore, the outer ring component is arranged outside the collar, and the tapered portion of the outer ring component is fixedly equipped with guide plates arranged in a ring array.

[0013] Furthermore, the shield has a fan-shaped structure, and the shield has conical grooves arranged in an arc.

[0014] Furthermore, the baffle plate is equipped with scraper strips at both ends of the inner ring on the centripetal side. The scraper strips are arranged at an angle, and a water collection block is fixedly installed at the bottom of the scraper strip. A water collection groove is opened on the inner side of the water collection block.

[0015] Furthermore, the centrifugal end of the scraper, away from the inner ring, extends into the outermost collar gap, and the water collection trough is inclined along the direction of the outermost collar gap.

[0016] Furthermore, the bottom of the rotating ring is provided with a linkage groove for storing the jetting cylinder, and an angle sensor is installed on the laser cutting body.

[0017] Compared with existing technologies, the multi-angle automated glass drilling laser cutting machine of the present invention has the following advantages: 1. This invention addresses the problem of insufficient cooling on the leeward side and asymmetrical thermal stress leading to cracks during tilted processing in traditional equipment due to unstable flow fields. First, this invention constructs a cooling enclosure coaxial with the laser beam around the processing point by having the cooling and chip removal components rotate synchronously with the rotating ring, isolating unstable external airflow and ensuring a stable cooling environment in space. Second, through gas-liquid synergy technology, the fine droplets generated by the atomizer are impacted and sheared by a high-speed airflow at a 45° angle, improving evaporation heat absorption efficiency and overcoming the effects of gravity and diffusion, achieving precise point delivery. Moreover, the angle-adjustable component captures the laser tilt angle in real time through an angle sensor, driving the spray cylinder to converge synchronously, ensuring that all nozzle axes always converge at the processing point. Combined with the spiral cooling area formed by the rotation of the annular array of spray nozzles, the cooling difference between the leeward and windward sides is completely eliminated, making the cooling rate consistent on both sides of the glass. This eliminates asymmetrical thermal stress at its source, significantly reducing the risk of cracking in brittle glass and improving processing quality and yield.

[0018] 2. This invention addresses the problem of chip retention and solidification / slag buildup caused by gravity failure during angled cutting. The invention utilizes a chip removal assembly to completely replace gravity and forcefully remove chips. This assembly forms a coaxial chip channel through multiple sets of rings. An external negative pressure pump establishes a continuous base negative pressure, while a rotating baffle periodically sweeps across the channel outlet, generating high-frequency pulsed strong negative pressure to provide powerful impetus for the chips. The conical structure of the outer ring, in conjunction with the rotating guide plate, gathers scattered chips and imparts upward kinetic energy, significantly shortening their residence time within the cut and allowing the molten material to be discharged before solidification. Simultaneously, the arc-shaped conical groove of the baffle prevents chip rebound caused by channel blockage. The inclined scraper and centrifugal water accumulation block achieve self-cleaning of the chip removal channel, preventing dirt accumulation and obstruction of the flow field. Regardless of the cutting angle, the coaxial negative pressure suction always acts precisely on the processing point, effectively overcoming static friction and flow resistance in long cuts, physically eliminating slag buildup and ensuring a clean and smooth cut.

[0021] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0022] See Figures 1-3 As shown, this invention provides a multi-angle automated glass drilling laser cutting machine, including a laser cutting body 1. The bottom of the laser cutting body 1 is provided with a laser port 12 and a rotary connector 13. The rotary connector 13 has a hollow structure and is located at the bottom of the laser port 12. The laser inside the laser cutting body 1 can pass through the middle of the rotary connector 13. Its hollow structure provides a stable transmission path for the laser beam unaffected by rotational motion, ensuring that the laser can be emitted vertically and without obstruction. The rotary connector 13 includes a fixed ring 131 threadedly installed below the laser port 12 and a rotating ring 132 rotatably connected below the fixed ring 131. The rotary connector 13 is used to ensure a dynamic seal between the fixed ring 131 and the corresponding rotating ring 132, while simultaneously achieving stable transmission of gas and liquid media. The rotary connector 13 forms a reliable dynamic seal between the fixed ring 131 and the rotating ring 132, ensuring that the rotating ring 132 can perform 3... When rotating 60 degrees, cooling gas or liquid media can be stably and continuously delivered to the following cooling component 2, while preventing media leakage; a first motor 14 is mounted on the side wall of the fixed ring 131 via a motor mount, and the output end of the first motor 14 extends to the bottom of the motor mount and is equipped with a first gear 15. A first external gear ring 16 that meshes with the first gear 15 is fixedly mounted on the outer side of the rotating ring 132; the cooling component 2 is located on the lower inner side of the rotating ring 132 and is used to cool the glass cutting process; the angle adjustable component 211 is located on the side of the rotating ring 132 and is connected to the cooling component 2 for driving the cooling component 2 to rotate to different angles to achieve precise cooling; the chip removal component 3 is located on the upper inner side of the rotating ring 132 and is used to quickly remove the chips generated during laser cutting of glass.

[0023] It should be noted that the control system starts motor 14, which drives gear 15 to rotate. Gear 15 drives external gear ring 16 fixed on rotating ring 132, causing the entire rotating ring 132 to start rotating. Since cooling component 2 and chip removal component 3 are respectively located below and above the inner side of rotating ring 132, they rotate synchronously with rotating ring 132 and are aligned with the inclined machining surface. After the entire rotation is in place, angle adjustable component 211 finely adjusts the nozzle of cooling component 2 to ensure that the nozzle axis coincides with the local direction of the current cutting point. Cooling medium is stably delivered to cooling component 2 through the sealed channel of rotating connector 13 and vertically covers the laser spot with a uniform flow field. Since cooling component 2 is located below the inner side of rotating ring 132, it approaches the machining point before chip removal component 3 during rotation. Cooling medium first acts on the cutting area for efficient cooling. Subsequently, chip removal component 3, using its position above the inner side of rotating ring 132, quickly generates negative pressure after cooling to remove the chips and residual medium generated during cutting, forming an orderly medium flow path.

[0024] The synchronous rotation of the cooling component 2 and the chip removal component 3, driven by the rotating ring 132, forms a wall coaxial with the laser beam and with controllable direction around the laser processing point, isolating the processing area from the unstable external air environment. The cooling medium is vertically and evenly covered on the inclined surface from the nozzle, eliminating the difference between the leeward and windward sides, making the cooling rate on both sides of the glass consistent, effectively eliminating asymmetric thermal stress, and preventing the generation of additional cracks. At the same time, the cooling component 2 first cools the processing point, and the chip removal component 3 then removes the chips and medium, forming a closed loop of airflow path inside the cutting area, ensuring the stability of the cutting process and the processing quality.

[0025] It is worth noting that when the laser beam cuts perpendicularly to the glass surface, the system is in its baseline state. At this time, the nozzle of the cooling component 2 is already preset to a tilted state at a certain angle to the vertical direction, so that the sprayed cooling medium can effectively cover the vertical sidewall being processed. When the laser beam begins to tilt and cut into the glass at an angle, the angle adjustable component 211 immediately comes into play. The control system sends the tilt angle parameter of the laser head to the angle adjustable component 211 simultaneously. The angle adjustable component 211 precisely drives the cooling component 2 according to the received angle signal, so that its nozzle is further deflected and adjusted based on the original tilted state, so that the cooling medium of the cooling component 2 is concentrated. Whenever the tilt angle of the laser beam changes, the angle adjustable component 211 will drive the cooling component 2 accordingly, so that its spray axis is always focused on the key point where the laser beam contacts the glass. This allows the cooling medium to be precisely injected into the narrow molten pool area formed by the laser spot in the most direct and concentrated path. Through this dynamic adjustment, the cooling medium is no longer scattered over a large area, but forms a precise focused energy directed towards the processing point, which greatly improves the cooling efficiency.

[0026] See Figure 2-7 As shown in the figure, the cooling assembly 2 includes a spray cylinder 21, a liquid inlet pipe 22, a liquid inlet 23, a spray nozzle 24, an atomizer 25, an air inlet pipe 26, an air inlet 27, and a jet nozzle 28. Multiple spray cylinders 21 are arranged in a ring array at the bottom of the rotating ring 132. The liquid inlet pipe 22 is installed at the inlet end of the spray cylinder 21. The liquid inlet 23 is installed on the side wall of the fixed ring 131 and connected to an external water pump. The end of the liquid inlet pipe 22 away from the spray cylinder 21 passes through the rotating ring 132 and extends into the fixed ring 131, sealingly communicating with the liquid inlet 23. The spray nozzle 24 is installed at the end of the spray cylinder 21 away from the liquid inlet pipe 22. Each set of spray nozzles 24 rotates... The bottom of ring 132 is inclined towards the inner ring; atomizer 25 is fixedly installed at the end of nozzle 24 away from spray cylinder 21, and one end of air inlet pipe 26 is connected to the inner cavity of nozzle 24; air inlet 27 is installed at the end of fixed ring 131 away from liquid inlet 23, and the other end of air inlet pipe 26 passes through the inside of rotating ring 132 and extends into fixed ring 131, and is sealed and connected to air inlet 27; air jet 28 is opened at the end of nozzle 24 away from spray cylinder 21, and the inlet end of air jet 28 is connected to air inlet pipe 26, and the nozzle direction of air jet 28 forms a 45° angle with the atomizing spray direction of atomizer 25.

[0027] It should be noted that after the control system is started, it drives motor 14, which in turn drives the rotating ring 132 and the cooling assembly 2 mounted on it to rotate as a whole through gear transmission. When cooling is required, the cooling assembly 2 is activated, and an external water pump pumps coolant into the inlet 23. The coolant is then delivered to the nozzle 24 via the inlet pipe 22 and the spray tube 21. Finally, the coolant is converted into a fine and uniform atomized medium by the atomizer 25. At the same time, compressed gas supplied by an external air source is ejected at high speed from the jet nozzle 28, which forms a 45° angle with the atomized flow, through the air inlet 27 and the air inlet pipe 26. The core of this design lies in gas-liquid synergy, referencing... Figure 7 The gas-liquid indicator shows that the high-speed airflow ejected from the nozzle 28 at a 45° angle acts on the atomized medium coming out of the atomizer 25, producing two key effects. First, the airflow impacts and shears the droplets, making them finer and increasing the evaporation heat absorption efficiency, which can absorb heat from the glass to reduce thermal stress. Second, the high-speed airflow can precisely blow the atomized medium to the processing point where the laser spot is located, overcoming the diffusion of the atomized flow itself and the influence of gravity, and achieving long-distance, high-precision point cooling.

[0028] See Figure 2 and Figure 8 As shown, the nozzle 24 is a plate-shaped structure, and each group of nozzles 24 is arranged vertically at an angle along the centripetal direction of the fixing ring 131.

[0029] Because the multiple nozzles 24 are arranged in a ring array and have a plate-like structure, when they are all tilted towards the center, they collectively construct a three-dimensional, conical cooling wall from all directions. Since each set of nozzles 24 is pre-set to be tilted towards the center, its jet stream forms an inclined straight line pointing towards the central processing point. This inclined straight line wall completely surrounds the laser beam and its processing point, achieving 360° surround cooling without dead angles. Moreover, multiple such trajectory lines rotate at high speed at equal intervals, forming a continuous and dense spiral cooling area around the laser processing point (see...). Figure 8 The spiral-shaped cooling medium provides uninterrupted continuous cooling, and it also generates strong shearing and stirring effects on the air and steam environment around the processing point, forming efficient turbulence and further improving the cooling effect and uniformity.

[0030] See Figure 9 and Figure 12As shown, the chip removal assembly 3 includes a collar 31, a connecting block 32, an air extraction port 33, an inner ring 34, and a baffle plate 35. Multiple collars 31 are provided, and the diameter of each set of collars 31 gradually increases radially. The gap between each set of collars 31 forms a chip channel. The top of each set of collars 31 is installed inside the hollow fixed ring 131, and the bottom of each set of collars 31 passes through the rotating ring 132. The fixed ring 131 has symmetrically arranged chip grooves 130 inside, and the chip grooves 130 are connected to the air extraction port 33. The debris channel and debris groove 130 correspond to each other; the connecting block 32 has a plate-like structure and is arranged along the circumferential direction and fixedly installed between each set of collars 31; the air extraction port 33 is installed on one side of the laser port 12 and is connected to an external air pump; the inner ring 34 is sleeved on the bottom wall of the rotating ring 132; there are two inner rings, and two baffles 35 are symmetrically installed at the left and right ends of the inner ring 34 to block the gaps between multiple sets of collars 31, so as to improve the negative pressure capacity of the collars 31, and the baffles 35 are set inside the rotating ring 132.

[0031] It should be noted that when laser cutting begins, the external negative pressure air pump starts, continuously evacuating the debris channel 130 inside the fixed ring 131 through the air extraction port 33. Since the debris channel precisely corresponds to and connects with the upper debris channel 130, a stable, top-down basic negative pressure airflow is formed inside the entire static collar 31. Guided by this basic negative pressure, the glass debris generated during cutting is drawn into the debris channel between the collars 31, passes through the debris channel 130, and is ultimately quickly discharged. It is worth noting that when the rotating ring 132 drives its two symmetrical... When the baffle 35 starts to rotate, the rotating baffle 35 will periodically sweep across the gap outlet between the stationary collars 31. When the outlet of a certain debris channel is approached and covered by the baffle 35, the cross-sectional area of ​​the airflow in that local channel suddenly decreases. According to the principle of fluid dynamics, under the condition that the air flow rate is relatively constant, the airflow velocity at this point will suddenly increase, thereby generating a stronger local negative pressure in that specific channel. As the baffle 35 continues to rotate, this strong suction pulse will appear cyclically in different debris channels at extremely high frequency. This invention uses multiple sets of rings 31 with increasing diameters, precisely positioned outside the central axis of the laser beam, surrounding the laser processing point. The purpose is to physically isolate the high-energy laser processing area from the external environment, forming a dynamic purification barrier. This barrier enables regional management of the entire process of chip generation, capture, and transport. Chips are drawn into a preset flow field the instant they are generated, ensuring the processing area remains highly clean and significantly improving chip removal efficiency and kerf quality. In traditional angled cutting, the molten material has ample time to contact the relatively low-temperature kerf wall and re-solidify, forming difficult-to-remove slag. The dynamic purification barrier of this invention greatly shortens the contact time between the molten material and the kerf wall, allowing it to be discharged while still fluid, thus physically preventing slag formation and ensuring a clean and smooth kerf. Moreover, regardless of the change in cutting angle, the axial suction of the chip removal component 3 of this invention always exists and remains in the same direction, always coaxial with the laser beam, ensuring that the point of strongest suction is always aligned with the current processing position. It completely replaces the role of gravity in vertical cutting, ensuring that the chips can be forcibly pulled out of the cut and transported away, fundamentally solving the problem of chip retention caused by gravity failure.

[0032] See Figure 2 and Figure 9 As shown, a hollow outer ring 36 is fixedly installed at the bottom of the rotating ring 132, and a baffle plate 35 is fixedly connected to the top of the inner ring of the outer ring 36. The inner side of the outer ring 36 is arranged in a conical structure.

[0033] It should be noted that the conical structure forms a funnel-shaped channel that tapers inward from bottom to top. This funnel-shaped channel can effectively guide and converge the scattered debris splashed from the cutting area to the chip channel inlet of the collar 31 of the chip removal assembly 3 above. It prevents the debris from randomly impacting and rebounding under negative pressure, but instead organizes it into an optimal path leading to the chip removal channel, which significantly improves the efficiency of debris capture and reduces secondary deposition near the processing area.

[0034] It is worth noting that the baffle plate 35 and the outer ring 36 are fixedly connected. When the rotating ring 132 rotates, it drives the baffle plate 35 and the outer ring 36 to rotate synchronously, thereby enabling the baffle plate 35 to rotate on the collar 31, which is used to intermittently generate a stronger local negative pressure.

[0035] See Figure 2 and Figure 9 As shown, the outer ring 36 is arranged outside the collar 31, and the tapered part of the outer ring 36 is fixedly installed with guide plates 37 arranged in a ring array.

[0036] When the guide plates 37 rotate at high speed with the system, they actively pump the debris below upwards and throw it toward the debris channel inlet of the stationary collar 31 above. Before entering the static negative pressure suction zone, the debris has been given additional kinetic energy and an upward initial velocity by the guide plates 37, which greatly reduces the suction load of the chip removal assembly 3, enabling it to remove heavier and larger debris with less energy. Moreover, the powerful axial airflow generated by the rotation can effectively sweep the machining surface, prevent light debris from settling and accumulating around the cutting area, and ensure that all products are drawn into the chip removal flow.

[0037] At the same time, the rotation of the guide plate 37 creates a high-speed rotating, centripetal air curtain barrier in the spray area of ​​the cooling component 2. This rotating air curtain can effectively constrain the atomized medium sprayed by the cooling component 2, prevent it from spreading ineffectively to the outside, and force it to be sprayed more concentratedly towards the laser processing center area, significantly improving the utilization rate of the cooling medium and its concentration at the processing point.

[0038] See Figure 12 As shown, the shielding plate 35 has a fan-shaped structure, and the shielding plate 35 has a conical groove 351 arranged in an arc.

[0039] It is important to note that when the rotating baffle 35 is about to completely cover a debris channel, without the conical groove 351, the channel would be instantly and completely closed, creating a brief blind spot. The presence of the arc-shaped conical groove 351 is equivalent to creating a gradually narrowing guide slot in advance on this "door" that is about to close. It allows airflow and debris to be guided in an orderly manner through this specific conical groove 351 in the last moment before being completely blocked, as well as in the early stage of being blocked. This avoids the risk of large pieces of debris bouncing back at the entrance of the channel due to instantaneous blockage, ensuring the continuity and smoothness of the debris removal process.

[0040] See Figure 12 and Figure 13 As shown, the baffle plate 35 is equipped with scraper strips 341 at both ends of the centripetal side of the inner ring 34. The scraper strips 341 are arranged at an angle. A water collection block 342 is fixedly installed at the bottom of the scraper strips 341. A water collection groove is opened on the inner side of the water collection block 342.

[0041] It should be noted that as the baffle plate 35 rotates, the bottom edge of the inclined scraper 341 slides closely against the bottom surface of the lower collar 31. This rotating scraping action actively and in real time removes the mixed dirt, coolant, and glass dust adhering to the surface, preventing it from accumulating and hardening into hard-to-remove clumps. This maintains the original geometry and smoothness of the chip removal channel inlet area, ensuring smooth airflow. The wet debris scraped off by the scraper 341 is guided along its inclined installation angle and collected in the water collection tank of the dedicated water collection block 342. The mixed dirt collected in the water collection tank is not permanently collected, but is directly exposed to the powerful negative pressure suction flow field inside the collar 31. The chip removal suction will continuously draw away the liquid and debris mixture accumulated in the water collection tank.

[0042] See Figure 2 and Figure 9 As shown, the centrifugal end of the scraper 341, away from the inner ring 34, extends into the gap of the outermost collar 31, and the water collection trough is inclined along the gap of the outermost collar 31.

[0043] It should be noted that when the rotating ring 132 drives the scraper 341 to rotate, it generates a strong centrifugal force. Since the centrifugal end of the scraper 341 extends into the gap of the outermost collar 31, and the water collection tank is inclined along the direction of the outermost gap, it effectively overcomes the resistance of the mixture flowing in the tank, actively and quickly throws the dirt into the negative pressure debris channel inlet, improves the efficiency and thoroughness of self-cleaning, and avoids secondary deposition of dirt inside the cleaning system.

[0044] See Figures 4-6As shown, the bottom of the rotating ring 132 has a linkage groove 133 for storing the spray cylinder 21. An angle sensor 11 is installed on the laser cutting body 1. The angle adjustable component 211 includes a rotating shaft 212, a drive plate 213, a radial block 214, a limiting block 215, a second external gear ring 216, a rotating ring 217, a second motor 218, a second gear 219, and a compression spring 2191. The rotating shaft 212 is installed in the linkage groove 133 and is fixedly connected to the spray cylinder 21. One end of the drive plate 213 is rotatably connected to the spray cylinder 21 via a hinge. The radial block 214 is slidably connected to the bottom of the rotating ring 132 via a slide rail, and the other end of the drive plate 213 is connected via a hinge. The chain and radial block 214 are rotatably connected; the limiting block 215 is installed below the radial block 214; the second external gear ring 216 is rotatably connected to the outside of the rotating ring 132; the rotating ring 217 is installed inside the second external gear ring 216, and a limiting groove is opened in the second external gear ring 216 on the side corresponding to the limiting block 215, and the limiting block 215 is slidably connected inside the limiting groove; the second motor 218 is installed on one side of the rotating ring 132 through the motor base; the second gear 219 is fixedly connected to the output end of the second motor 218 through the motor base and meshes with the second external gear ring 216; the compression spring 2191 is installed in the linkage groove 133, and one end of it is fixedly connected to the bottom of the spray cylinder 21.

[0045] It should be noted that when performing tilt cutting, the angle sensor 11 detects the change in tilt angle of the laser cutting body 1 in real time and sends this signal to the control system. The control system calculates the angle required for the nozzles to converge to maintain the cooling focus according to the preset algorithm, and then sends a drive command to the second motor 218. The second motor 218 starts and drives the second gear 219 to rotate in the opposite direction. The second gear 219 drives the second external gear ring 216 that meshes with it to rotate. The second external gear ring 216 drives the inner rotating ring 217 to rotate synchronously. The limiting groove on the rotating ring 217 rotates accordingly. Since the limiting block 215 slides in the limiting groove, the limiting groove will force all the limiting blocks 215 to slide along the slide rail towards the centrifugal end of the laser cutting body 1. The movement of each limiting block 215 is transmitted to the rotating shaft 212 through the radial block 214 and the drive plate 213 above, thereby driving all the spray tubes 21 and the atomizer 25 at the top to rotate inward to achieve synchronous convergence.

[0046] This invention achieves this by increasing the tilt angle of the laser head, which in turn causes the control system to instruct the second motor 218 to rotate at a greater angle. This results in a higher degree of convergence of all atomizers 25. Regardless of the laser head's tilt angle, the invention ensures that the jet axes of all atomizers 25 always converge at the processing point where the laser spot is located, forming precise focused cooling. This ensures that the cooling medium always acts on the center of the heat source with maximum efficiency, avoiding the drawbacks of the cooling medium evaporating or only acting on one side of the cut during tilted cutting. Furthermore, it ensures that the cooling rate is consistent on both sides of the tilted cut, further preventing glass cracks caused by uneven heating. It is worth noting that when the laser beam is perpendicular to the glass surface, the cutting depth is equal to the glass thickness, the kerf is short and straight, and the debris is most easily discharged. However, when the laser beam is tilted, the situation changes fundamentally. After the laser beam is tilted, the effective path length for it to penetrate inside the glass, i.e., the kerf length, is no longer the glass thickness. This longer tilted kerf means that debris, especially in the molten state, needs to travel a greater distance to be discharged. The continuous strong negative pressure and intermittent pulse suction established by the chip removal component 3 at the processing point entrance of this invention, through the axial suction provided by the chip removal component 3, completely replaces the role of gravity in vertical cutting, and is more powerful and proactive. It provides a strong power source with a constant direction for the movement of debris in the long tilted kerf. No matter how long the kerf is or how large the angle is, this suction always acts on the kerf exit, continuously drawing debris out from the depth of the kerf, overcoming huge static friction and flow resistance.

[0047] Working principle: When using a multi-angle automated glass drilling and laser cutting machine, follow these steps: The laser generated by the laser cutting body 1 passes through the hollow structure of the rotating connector 13 via the laser port 12 and is focused on the glass processing point without interference. The control system starts the first motor 14, which drives the rotating ring 132 to rotate through the meshing of the first gear 15 with the first external gear ring 16. The dynamic seal formed by the rotating connector 13 ensures that the cooling medium is stably transmitted to the following cooling component 2. At the same time, the cooling component 2 and the chip removal component 3 rotate synchronously with the rotating ring 132 to achieve a surrounding coverage of the processing area. The angle sensor 11 of the laser head detects the tilt angle in real time and transmits the signal to the control system. The system commands the second motor 218 to drive the second gear 219 to rotate. Through the transmission structure such as the second external gear ring 216, the rotating ring 217, and the limit block 215, the radial block 214 is pushed to slide, which in turn drives the spray cylinder 21 to rotate through the drive plate 213, so that the atomizer 25 is synchronously focused with the laser tilt angle to ensure that the spray axis intersects at the processing point. An external water pump and an air source respectively deliver coolant and compressed gas to the nozzle 24 through the liquid inlet 23 and the air inlet 27. After the coolant is atomized by the atomizer 25, it works in conjunction with the high-speed airflow ejected at an angle of 28° from the nozzle to form fine droplets that precisely act on the processing point. An external negative pressure air pump forms a basic negative pressure in the gap of the collar 31 through the air extraction port 33. The rotating baffle 35 periodically sweeps across the gap to generate pulsed strong negative pressure. The conical structure of the outer ring 36 and the rotating airflow of the guide plate 37 converge the debris. The arc-shaped conical groove 351 of the baffle 35 ensures the continuity of chip removal. The scraper 341 and the water accumulation block 342 achieve self-cleaning.
